Referring to fig. 1 to 11, a schematic configuration of the printing consumable loading mechanism 1 and a positional relationship between the respective configurations will be described. The printing consumable loading mechanism 1 comprises a printing consumable 10 arranged in a paper feeding channel of the printing consumable loading mechanism 1, a power part 3 consisting of a spring 31 and a pulley assembly 30, a linkage part 6 consisting of a sliding rail 42, a sliding block 43 (44) and a gear 66, a rack 60 (61), an automatic release device 2 consisting of a transverse assembly 11 in a first direction and a vertical assembly 12 in a second direction and capable of automatically releasing the printing consumable 10, and a left loading support plate 53 (54) and a right loading support plate 53 (54) which connect the printing consumable loading mechanism 1 and the printing consumable 10. The two loading plates 53 (54) directly act on the printing consumables 10 and are fixed on the left and right pads 51 (52) moving along with the movement of the sliders 43 (44).
The transverse combination 11 comprises a first block 22 fixed on any one of the left pad 51 or the right pad 52 through two side arch grooves, a first elastic block 28 capable of contacting with the vertical combination to press the first block, a groove part 27 capable of accommodating the first elastic block, and a clamping shell piece 29 clamped on any one of the left side or the right side of the first elastic block 28 and two sides of the first block 22 to prevent the first block 22 and the first elastic block 28 from sliding freely. And sequentially traverses a transverse axis 23 in a first direction. The lateral shaft 23 is fixed to the backing plate 51 (52).
The vertical combination 12 comprises a second block 21 perpendicular to the first block, a second elastic block 25 in contact with the first elastic block 28 for movement, a hexagon screw 26 and a spring 24. The second block 21 is fixed to one end of the base plate 41 of the interlocking section 3 through two circular holes 201 (202) therebelow. The first direction is a direction parallel to the horizontal direction of the spring 31 and the pulley combination 30, and the second direction is a direction perpendicularly intersecting the spring 31 and the pulley combination 30.
The horizontal combined body 11 and the vertical combined body 12 are in contact with each other through two irregular blocks (25, 28) respectively located in the first direction and the second direction.
The horizontal combination body 11 and the vertical combination body 12 are interlocked by the contact of the first elastic block 28 and the second elastic block 25. The second elastic block 28 is connected with the hexagon screw 26 through the thread on the hexagon screw 26, and the height of the second elastic block can be automatically adjusted according to the situation.
On the left or right side in the first direction of the second block 21, there are two first groove portions 211 and second groove portions 212 which are open to the right in the first direction and are open to the upper and lower sides in the second direction, respectively. The first groove portion 211 and the second groove portion 211 communicate with each other through a hole. A hexagonal screw 26 is connected to the second spring block 25 through the communication hole from below in the second direction.
The spring 24 is located in the space above the communication hole and below the second spring block 25 in the first groove 211 to provide a supporting force for the up-and-down movement of the second spring block 25.
When the printing consumables 10 are applied with force to one of the left and right loading plates 53 and 54, the interlocking portion 6 moves, and the automatic release device 2 moves in an interlocking manner. When the stroke is near the end, the automatic release preventing device 2 can be blocked, so that the printing consumable loading mechanism 1 basically reaches the maximum stroke, namely the distance between the loading support plates 53 and 54 is maximum, and the printing consumable 10 is convenient to disassemble and assemble.
After the printing consumables 10 are loaded into the printing consumables loading mechanism 1, pressing down the loading support plate 53 (54) from the first direction causes the two loading support plates 53 (54) of the printing consumables loading mechanism 1 to be clamped towards the middle continuously again, so that the printing consumables 10 are released or clamped.
The interlocking part 6 drives the power part 3 and the automatic releasing device 2 to move due to the movement of the loading support plate 53 (54) caused by the installation or the removal of the printing consumables 10. The interlocking part 6 composed of the sliding rail 42, the gear 66, the rack 60 and the rack 61 comprises a concave base plate 41 and a convex sliding rail 42, two sliding blocks 43 and 44 which are parallel and are mutually matched with the convex of the sliding rail 42 in the third direction, two racks 60 and 61 which are parallel and are mutually matched with the convex of the sliding rail 42 in the first direction, a gear 66 which moves synchronously with the racks 60 and 61 in the first direction, and a third block 64 which is fixed at the central position of the base plate 41.
The gear 66 and the third block 64 are fixed together by a solid pin 65. The slide rail 42 is fixed to the base plate 41 by screws, and one ends of the two racks 60 and 61 are fixed to the upper surface of one of the left pad 51 and the right pad 52. The printing consumables loading mechanism 1 and the printing consumables 10 are connected by two left and right loading brackets 53 (54) directly acting on the printing consumables 10. Two support plates 53 (54) fixed to the left pad plate 51 and the right pad plate 52, respectively. And the left pad 51 and the right pad 52 are fixed on the left and right sliders 43 (44), respectively.
The movement of the loading support plate 53 (54) caused by the installation or the removal of the printing consumables 10 can drive the pad 51 (52) fixed to the loading support plate 53 (54) to move, so as to drive the slider 43 (44) fixed to the pad 51 (52) to move, and the linkage action can cause the power part 3, the automatic release device 2 and the linkage part 6 to simultaneously move at the same time, so that the effects of automatically releasing the printing consumables 10 and automatically clamping the printing consumables 10 are achieved.
The pulley assembly 30 constituting the power unit 3 includes a movable pulley body 33, a fixed pulley body 32, and a pulley rope 34. Which is fixed to the right shutter in the first direction in the printer housing through the right end in the first direction of the fixed pulley body 32. Which is connected to the left end portion of the spring 31 in the first direction through the left end of the movable pulley body 33 in the first direction. Which connects the fixed pulley body 32 and the movable pulley body 33 by a pulley cord 34. One end of the pulley rope 34 is fixed to the right end of the movable pulley body 33 in the pulley assembly 30 in the first direction, and the other end thereof is fixed to one of the left pad 51 and the right pad 52.
The spring 31 provides power to continuously clamp the loading support plate 53 (54) towards the middle, the left end of one of the two ends of the spring 31 in the first direction is fixed on the left baffle plate in the printer casing in the first direction, and the right end of the other end is fixed on the left end of the movable pulley body 33 in the pulley combination in the first direction. The pulley combination 30 can reduce the working length of the spring 31 in the power part 3 and the force difference between the initial force and the final force under a large stroke.
The printing consumables loading mechanism 1 and the printing consumables 10 are connected by two left and right loading brackets 53 (54) directly acting on the printing consumables 10. Two loading brackets 53 and 54 are fixed to the left pad 51 and the right pad 52, respectively. And the left pad 51 and the right pad 52 are fixed on the left and right sliders 43 (44), respectively. The movement of the loading plate 53 (54) caused by the installation or the removal of the printing consumables 10 drives the pad 51 (52) fixed to the loading plate 53 (54) to move, so as to drive the pulley assembly 30 to move, and the spring 31 generates the stretching movement and generates the momentum.
Referring to fig. 3 to 4, the state of the printing consumable loading mechanism 1 when a wide printing consumable and a narrow printing consumable are loaded will be briefly described.
Fig. 3 shows a state of the printing consumable loading mechanism 1 when a wide printing consumable is loaded, where a state is selected when the stroke distance between the two loading plates 53 (54) is maximum. Fig. 4 shows a state of the printing consumable loading mechanism 1 when a narrow printing consumable is loaded, in which a state in which the stroke distance between the two loading plates 53 (54) is minimized is selected.
When a wide printing consumable is loaded, the printing consumable loading mechanism 1 is in an initial state where a wide consumable 10 is loaded, as shown in fig. 3. At this time, the distance of travel between the two loading support plates 53 and 54 reaches the maximum, so that the printing consumables 10 can be conveniently put in or taken out.
After the consumable 10 is put in, one of the lower left loading support plate 53 or the right loading support plate 54 is pressed, the linkage action of the support plates enables the spring 31, the pulley blocks 30 and the automatic release device 2 to simultaneously and instantaneously move, and the second elastic block 25 in the automatic release device 2 is separated from the state of being clamped at the middle position of the groove part 27 and the first elastic block 28, so that the printing consumable 10 put in under the initial clamping state is achieved.
After the consumable 10 is taken out, any one of the left loading support plate 53 and the right loading support plate 54 is pressed, the linkage action of the support plates enables the spring 31, the pulley blocks and 30 and the automatic release device 2 to simultaneously and instantaneously move, and the second elastic block 25 in the automatic release device 2 is separated from the state of being clamped at the middle position of the groove part 27 and the first elastic block 28, so that the printing consumable 10 put in under the initial state is released.
When a narrow printing consumable is loaded, as shown in fig. 4, the printing consumable loading mechanism 1 is in an initial state of loading the narrow consumable 10, and the stroke distance between the two loading support plates 53 and 54 is maximized, so that the printing consumable 10 can be conveniently put in or taken out.
After the consumable 10 is put in, one of the lower left loading support plate 53 or the right loading support plate 54 is pressed, the linkage action of the support plates enables the spring 31, the pulley blocks 30 and the automatic release device 2 to simultaneously and instantaneously move, and the second elastic block 25 in the automatic release device 2 is separated from the state of being clamped at the middle position of the groove part 27 and the first elastic block 28, so that the printing consumable 10 put in under the initial clamping state is achieved.
After the consumable 10 is taken out, any one of the left loading support plate 53 and the right loading support plate 54 is pressed, the linkage action of the support plates enables the spring 31, the pulley blocks and 30 and the automatic release device 2 to simultaneously and instantaneously move, and the second elastic block 25 in the automatic release device 2 is separated from the state of being clamped at the middle position of the groove part 27 and the first elastic block 28, so that the printing consumable 10 put in under the initial state is released.
Note that: the status of the printing consumables loading mechanism 1 in fig. 3 can be an initial status of loading the wider consumables 10, but the status of the printing consumables loading mechanism 2 in fig. 4 can be an initial status of loading the narrower consumables 10 or a release status after releasing the consumables 10 completely.
Referring to fig. 11, the movement process and principle of the automatic release device 2 will be explained.
When the printing and loading mechanism 1 is in the second state shown in fig. 4, i.e. the state after the consumable 10 is completely released, and the printing and loading consumable is loaded on the loading mechanism, force can be applied to the left and right loading support plates, i.e. one of the left loading support plate 53 or the right loading support plate 54 is pressed to move outward, so that the transverse group and the body 11 in the automatic releasing device 2 move outward at the same time, the groove 27 in the transverse combination body 11 first contacts with the inclined surface of the second block 25 in the second block 21, and as the loading support plates 53 (54) continue to move outward, after the groove 27 contacts with the top of the second block 25 (fig. 11-a), the second block 25 is clamped between the groove 27 and the first block 28, and at this time, the notch of the groove 27 contacts with the right side of the second block in the first direction, that is fig. 11- (b), the state of the printing supplies loading mechanism 1 at this time is shown in fig. 3, and the stroke distance between the two loading plates 53 and 54 is maximized, so that different types of printing supplies can be loaded.
After the printing supplies are loaded, force is applied to the left and right loading support plates again, that is, any one of the lower left loading support plate 53 or the right loading support plate 54 is pressed again to move outwards, and along with the movement, the second elastic block 25 contacts with the top of the first elastic block 28 (figure 11-c), after the second elastic block 25 passes over the top of the first elastic block 28 (figure 11-d), the printing supplies loading mechanism 1 starts moving back inwards, and the first elastic block 28 moves into the bowl-shaped groove part 27 along with the above-mentioned moving back, when the second elastic block 21 is moved back to the opposite side of the notch of the groove 27, the printing supplies loading mechanism 1 is instantaneously moved to the initial state of loading the printing supplies, i.e., the second state of fig. 4, thereby achieving the effect of automatic clamping and automatic release without motor drive and without circuit control.
In the above process, the automatic releasing device 2 is preferably based on the following structural principle: the interlocking of the interlocking part 6 and the power part 3 is mainly caused by the mutual contact and actuation of the first elastic block and the second elastic block, so that the printing consumables are automatically fastened and automatically released (as shown in figures 7, 8, 9, 10 and 11).
The operation of the printing supplies loading mechanism 1 in the present invention is improved in that no motor drive is required without circuit control.
In the printer in the prior art, when the printing consumables 10 are assembled and disassembled, a power supply needs to be inserted first, and a series of linkage actions can be generated under the driving action of a circuit control motor. However, in the printing consumables loading mechanism 1 of the present invention, due to the existence of the automatic releasing device 2, when there is no function of the circuit control motor drive, the automatic clamping and automatic releasing of the printing consumables 10 can still be realized.
The operation of the printing supplies loading mechanism 1 in the present invention is improved in that it is not necessary to measure the specifications such as the width of the printing supplies 10.
In the printer in the prior art, the phenomenon that the printing consumables 10 are stuck by the fixed loading support plate can occur. The printing consumable loading mechanism has the advantages that due to the existence of the spring 31 and the pulley blocks and 30, the printing consumable loading mechanism 1 has scalability, and the phenomenon is effectively avoided.
The printer in the prior art mostly adopts the lead screw transmission to link the loading support plate of the printing consumables so as to achieve the effect of loading and unloading the printing consumables 10, and simultaneously is connected with the driving motor through gear engagement, belt connection, synchronous belt connection, chain connection or electromagnetic attraction mode so as to enable the lead screw to move.
