Fig. 2 is the structural representation of described wiping head;
Fig. 3 is the structural representation of described hollow tube.
[specific embodiment]
Below in conjunction with the description of drawings and the specific embodiment the utility model one is gone on foot explanation.
As shown in figures 1 and 3, a kind of dust-collecting type blackboard eraser device, this device is installed on the plate face, and it comprises support 8 and is installed in wiping that the drive motors 1 on the described support 8, the transmission mechanism 2 that is connected in described motor 1 output, described transmission mechanism 2 link to each other 3, this wiping 3 linear moving; Described wiping 3 comprises wiping cylinder 31 and the wiping depression bar 32 that is set up in parallel with it.
The end of described wiping depression bar 32 is set on the axle of described wiping cylinder 31, and the rotation of described wiping cylinder 31 drives described wiping depression bar 32 deflections.
Comprise two described wiping depression bars 32, these described wiping cylinder 31 both sides, two described wiping depression bars, 32 offices also are symmetrical arranged.
Described transmission mechanism 2 comprises gear drive and tooth bar transmission, and this horizontally disposed described tooth bar 21 drives described wiping head and moves in the horizontal direction.Described transmission mechanism 2 rotates wiping cylinder 31 through the two-stage gear drive, the rotating speed of wiping cylinder 31 is provided and turns to the wiping action first time of realization wiping arrangement; This transmission mechanism 2 makes wiping cylinder 31 move relative to the plate face through the engagement of wheel and rack 21 in addition.Should move one side and make the scroll zones of wiping cylinder 31 cover whole plate face, and on the other hand, drive wiping depression bar 32 and realize secondary wiping action, so that the plate face is cleaner.
In the end of described tooth bar 21 limit switch 4 is set.
Described wiping cylinder 31 comprises a hollow tube 41 and the flannelette that circumferentially centers on thereof, and offers a plurality of sieve apertures 42 on this hollow tube 41.Described wiping depression bar 32 comprises a bar and the flannelette that circumferentially centers on thereof.Flannelette on wiping cylinder 31 and the wiping depression bar 32 is to bond on hollow tube and the bar with convenient.When the long-time use of flannelette warp is dirty or damaged, cleaning that flannelette is taken off or replacing very easily.
In the bottom of described hollow tube 41 induced-draught fan 6 is installed, its rear portion is provided with collects box 7.Dust on the flannelette enters hollow tube by sieve aperture 42, enters via the suction dust of induced-draught fan 6 and collects box 7.
Two ends in described wiping 3 are provided with the adjustment screw 5 that is used to regulate pressure, increase or reduce pressure between wiping cylinder and the plate face by regulating adjustment screw 5, have avoided the dust pollution air to help the dust absorption.
At the lower end of described wiping 3 and described tooth bar 21 guide rail that be arranged in parallel, the wiping head is along upper rack and lower guideway steady shift like this.
The operation principle of the utility model dust-collecting type blackboard eraser device is:
By motor-driven, the wiping cylinder reverse rolling, be that wiping cylinder is identical with the direction of advance of wiping cylinder with the peripheral speed direction of plate face contact position, the speed that relative sliding velocity between wiping cylinder circumference and plate face moves along the plate face greater than wiping cylinder realizes the first level wiping by the friction between flannelette on the wiping cylinder and plate face.Simultaneously, wiping depression bar and wiping cylinder move with respect to the plate face together, realize the wiping of second level by the friction between flannelette on the wiping depression bar and plate face.By this compound wiping process, the writing on the plate face is able to remove more up hill and dale.
Wiping for the first time: wiping cylinder carries out wiping to the plate face:
The wiping cylinder reverse rolling, the speed that the relative sliding velocity between its circumference and plate face moves along the plate face greater than wiping cylinder realizes wiping for the first time by the friction between flannelette on the wiping cylinder and plate face.
Wiping for the second time: the flannelette depression bar carries out wiping to blackboard simultaneously:
Wiping depression bar of the present utility model moves with respect to the plate face under the drive of wiping cylinder, drive the wiping depression bar by the frictional force between wiping depression bar and its rotating shaft simultaneously and make small angle deflection, thereby the left side of wiping depression bar or right side are contacted with the plate face, when wiping cylinder moves right, wiping depression bar in a left side contacts with the plate face, when wiping cylinder was moved to the left, right wiping depression bar contacted with the plate face.Realize secondary wiping by the friction between flannelette on the wiping depression bar and plate face.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
