detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

As shown in Figure 1, a kind of novel chalk wiper dust remover comprises a cabin 10, is provided with input port 20 in the described cabin 10, and described input port is provided with chalk wipe input device, and chalk wipe input device includes stretching into cabin The guide rail 310 in the room, the upper part of the guide rail 310 is provided with a slide seat 320 that cooperates with the guide rail to place the chalk eraser 100, the middle part of the guide rail 310 is provided with a screw rod, and the lower end of the slide seat 320 has a screw sleeve that matches the screw rod , the screw is driven by the conveying motor to drive the sliding seat 320 to move axially along the screw.

The sliding seat 320 in this embodiment uses a screw nut pair to realize the movement of the sliding seat 320 , of course, in actual use, the air cylinder can also be used to drive the sliding seat 320 to move so as to drive the transportation of the chalk eraser 100 .

A motor 40 is arranged on the side of the chalk eraser input device in the cabin, a disc 410 is fixed on the output end of the motor 40, and a flexible rope 420 is fixed on the disc 410, and a plurality of them are evenly distributed in the circle along the circumferential direction. On the disc 410, the material of the flexible rope 420 in the present invention can be made of plastics, fiber and metal, as long as the flexible rope 420 whips the chalk eraser 100 when the motor 40 is turned on.

The middle part of the sliding seat 320 has a groove 321, and the side of the groove 321 has a butterfly bolt 322 for locking the chalk eraser. By fixing the side of the chalk eraser, the chalk eraser 100 of different sizes can be locked to ensure that the chalk eraser 100 does not shift or fall during the process of being transported and slapped by the flexible rope 420 .

The inner wall of the cabin 10 is provided with an exhaust fan 50 , the outer end of the exhaust fan 50 is connected with a ventilation pipe 510 , and the outlet end of the ventilation pipe 510 is placed in a dust collection basin 520 . Liquid may be provided in the dust collection basin 520 to facilitate dust collection. After the flexible rope 420 whips the chalk eraser 100 when the motor 40 is turned on, the chalk dust stained on the chalk eraser 100 will be ejected, and then sucked by the exhaust fan 50 into the dust collection basin 520 through the ventilation pipe 510.

In order to prevent dust from escaping from the input port 20, the input port 20 is provided with a dust blocking brush 210, the dust blocking brush includes a fixed piece fixed in the cabin, and a brush is arranged on the lower end of the fixed piece.

For compact layout, the exhaust fan 50 and the motor 40 are arranged on both sides of the chalk eraser input device. In addition, in order to improve the efficiency of air extraction, ventilation holes are provided on the other side of the cabin corresponding to the exhaust fan, and the diameter of the ventilation holes is 3-5 cm.
