In addition, when the door panel 31 is located at the outer limit position, the door panel 31 just completely avoids the material leaking hole 11, see fig. 8, that is, the side edge of the innermost side of the door panel 31 is just tangent to the hole wall of the material leaking hole 11 close to the outer side or is very close to the hole wall of the material leaking hole 11. Preferably, when the door panel 31 moves from the outer limit position to the inner limit position, the bottom of the material leakage hole 11 is completely closed by the door panel 31 when the door panel 31 moves to 1/8 of the total stroke.
The purpose of the above design is: when the door panel 31 is located at the outer limit position, the powder falling from the material leaking hole 11 needs to directly fall into the collecting and dispersing cylinder 42 below, so when the material leaks, the collecting and dispersing cylinder 42 is located right below the material leaking hole 11, and then once the material leaking is stopped, the door panel 31 starts to move inwards from the outer limit position, and meanwhile, the rotating disc 41 also starts to rotate, so the collecting and dispersing cylinder 42 also rotates along with the material leaking hole, so as to avoid the situation that the material leaking hole 11 is not closed in the process, and the collecting and dispersing cylinder 42 already leaves the material dropping point, so that the material leaking hole 11 needs to be ensured to be closed as soon as possible, therefore, the door panel 31 located at the outer limit position is specially and just located near the material leaking hole 11, and moves inwards for a certain distance (1/8 of the total stroke), so that the material leaking hole 11 can be closed; thus, when the rotating shaft 51 rotates clockwise along the top view and the door panel 31 starts to move inwards from the outer limit position, the rotating disc 41 rotates a certain angle (90/8 degrees) slightly, the door panel 31 can close the bottom of the leaking hole 11, so that the door panel 31 closes the leaking hole 11 before the collecting and distributing cylinder 42 leaves the dropping point of the leaking hole 11, thereby ensuring that no powder falls into the collecting and distributing cylinder 42 when the powder falls down.
The automatic batching device of the invention has the functions of: the four different powders are allowed to fall into the collecting and dispersing cylinder 42 below in turn according to a predetermined weight ratio, and then all the powders fall into the magazine a below at one time by the collecting and dispersing cylinder 42 containing the four powders at a specific position, and then are conveyed from the magazine a to the next process.
The specific working principle is as follows:
when the device is not in operation, the device is in an initial state; at this time, the four door panels 31 are all located at the inner limit positions (see fig. 2, 6 and 7), and the bottoms of the four material leaking holes 11 are all closed; meanwhile, the four collecting and distributing cylinders 42 are respectively positioned right below the four material leaking holes 11, that is, the central axis of each collecting and distributing cylinder 42 is collinear with the central axis of one of the material leaking holes 11, referring to fig. 1 and 2, the bottoms of the four collecting and distributing cylinders 42 are attached to the annular cushion layer 62 and are sealed by the annular cushion layer 62; meanwhile, a plurality of material boxes a (only two material boxes are shown in fig. 1) are also placed on the belt 71 of the conveying mechanism 7, the intervals between the material boxes a are equal, the foremost material box a is positioned under the notch I621 and the notch II 611, the area of the top opening of the material box a is larger than the area of the notch I621/the notch II 611, namely, the projections of the notch I621 and the notch II 611 in the vertical direction can all fall into the cavity of the material box a, and the depth of the inner cavity of the material box a can ensure that powder falling from the bottom of the collecting and distributing cylinder 42 can not overflow after entering the material box a; the conveying direction of the belt 71 is conveying from the right side to the left side of fig. 1;
preparation before work: for convenience of understanding, in fig. 1 and 10, the four collecting and distributing cylinders 42 are respectively marked as four serial numbers i, ii, iii, and iv according to the rotation direction of the rotating disk 41, and in fig. 1, the four hoppers 2 are respectively marked as four serial numbers (i), (ii), (iii), and (iv) in a one-to-one correspondence manner with the four collecting and distributing cylinders 42; before starting, four kinds of powder materials to be proportioned are poured into the four hoppers 2 respectively, then the powder materials contained in the hopper with a preset amount are poured into the collecting and distributing cylinder 42 with the label II, the powder materials contained in the hopper with a preset amount and the hopper II are poured into the collecting and distributing cylinder 42 with the label III, the powder materials contained in the hopper with a preset amount, the hopper II and the hopper III are poured into the collecting and distributing cylinder 42 with the label IV, and no powder material is required to be poured into the collecting and distributing cylinder 42 with the label I;
when in work: firstly, the motor 52 rotates forward, the motor 52 drives the rotating shaft 51 to rotate a certain number of turns along the counterclockwise direction of the top view angle, in the process, the first gear transmission assembly 53 drives the four door panels 31 to move radially outwards, and the second gear transmission assembly 54 does not drive the rotating disc 41 to rotate; when the door panel 31 moves to the outer limit position (see fig. 8), the motor 52 is temporarily stopped, in the process, the bottoms of the four leakage holes 11 are opened, and the powder in the four hoppers 2 simultaneously falls, wherein the powder contained in the first hopper can fall into the collecting and distributing cylinder 42 with the reference number I, the powder contained in the second hopper can fall into the collecting and distributing cylinder 42 with the reference number II, the powder contained in the third hopper can fall into the collecting and distributing cylinder 42 with the reference number III, and the powder contained in the fourth hopper can fall into the collecting and distributing cylinder 42 with the reference number IV;
then, when the material leakage time reaches the preset time, the motor 52 rotates reversely, the motor 52 drives the rotating shaft 51 to rotate a certain number of times clockwise along the overlooking angle, in the process, on one hand, the first gear transmission component 53 drives the four door panels 31 to move radially inwards, and on the other hand, the second gear transmission component 54 drives the rotating disk 41 to rotate; when the door panel 31 moves to the inner limit position, the motor 52 is temporarily stopped, in this process, the bottoms of the four material leaking holes 11 are closed, the rotating disc 41 rotates 90 degrees counterclockwise in the overlooking angle together with the four collecting and distributing cylinders 42, and moves to the next grid, that is, the collecting and distributing cylinder 42 with the label I moves to the position where the collecting and distributing cylinder 42 with the original label II is located, the collecting and distributing cylinder 42 with the label II moves to the position where the collecting and distributing cylinder 42 with the original label III is located, the collecting and distributing cylinder 42 with the label III moves to the position where the collecting and distributing cylinder 42 with the original label IV is located, and the collecting and distributing cylinder 42 with the label IV moves to the position where the collecting and distributing cylinder 42 with the original label I is located; wherein, in the moving process of the collecting and distributing cylinder 42 with the number IV, the bottom of the collecting and distributing cylinder 42 with the number IV crosses the notch I621, so when the collecting and distributing cylinder 42 with the number IV moves to the upper part of the notch I621, all the powder in the collecting and distributing cylinder 42 falls down and then falls into the material box a which is stopped at the lower part in advance; after the powder in the collecting and distributing cylinder 42 with the reference number IV falls into the powder stored in the hopper IV, four kinds of powder are loaded in the collecting and distributing cylinder 42, so that the collecting and distributing cylinder belongs to the collecting and distributing cylinder 42 for completing the batching, and the powder loaded in the material box a is also the powder for completing the batching after the powder in the collecting and distributing cylinder 42 falls into the material box a;
then, the motor 52 rotates forward again to drive the rotating shaft 51 to rotate for a certain number of turns along the counterclockwise direction of the overlooking angle, and meanwhile, the conveying mechanism 7 is started to enable the belt 71 to drive the magazine a above to move forward for one grid, so that the next magazine a moves below the notch i 621 and the notch ii 611, after moving, a new magazine a is added on the belt 71, and the added magazine a needs to be placed at the starting end of the belt 71 (namely the rightmost side of the belt 71 in the figure); then, the automatic batching device continuously and circularly repeats the previous actions;
in the subsequent continuous cycle and repeat process, one collecting and distributing cylinder 42 can be used for completing the ingredient when the motor 52 completes the positive rotation once, and then when the motor 52 rotates reversely, the collecting and distributing cylinder 42 completing the ingredient can cross the notch I621, so that all the powder in the collecting and distributing cylinder 42 falls into the material box a below, and then the belt 71 drives the material box a to move forwards until the powder box a is conveyed to the subsequent process.
Therefore, in the process of completing powder proportioning, the invention not only can ensure that various powder materials are proportioned according to a preset proportion without weighing the powder materials one by one, but also saves the step of taking and placing a container in the patent with the application number of 202210052114.5. Therefore, the method has the advantages of higher automation degree and higher efficiency.
In the process, because the material leaking time is the same, the proportion of different powder materials is determined by the aperture size of each material leaking hole 11, for example, if the area of the material leaking hole 11 below the hopper (II) is twice of the area of the material leaking hole 11 below the hopper (I), when the motor 52 stops after rotating forwards, the volume of the powder materials falling from the hopper (II) is twice of that of the hopper (I), and therefore, according to the required material mixing proportion, the aperture size of each material leaking hole 11 is designed in advance to obtain the required material mixing proportion. In addition, since the blanking weight is determined by the material leakage time, the shutdown time interval after the forward rotation of the motor 52 can be preset according to the required final weight, so that the material with the required weight can be obtained. Wherein, the aperture of each material leaking hole 11 shown in the drawings of the description of the embodiment is consistent, so that the four powders are according to 1: 1: 1: 1, are dosed.
This embodiment is suitable for the formulation of four different powders, which can be dispensed into one magazine a in a specific ratio and in a specific total weight. If the amount of the powder type to be proportioned is changed, the corresponding amount of the parts or structures of the hopper 2, the material leaking hole 11, the door panel assembly 3, the second gear 533, the opening 91 and the distribution box 42 can be increased or decreased, for example, the powder to be proportioned contains six different powders, the amount of the hopper 2, the material leaking hole 11, the door panel assembly 3, the second gear 533, the opening 91 and the distribution box 42 can be designed to be six, and the sizes of other parts or structures can be adjusted adaptively, such as the size of the notch i 621 and the size of the distribution box 42.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
