[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] An embodiment of the present invention discloses a device for removing burrs from a plastic cover plate of a washing machine.

[0024] The present invention provides a Figures 1-3 As shown in the figure, a device for removing burrs from a plastic cover plate of a washing machine includes a base 1. A plurality of support rods 2 are fixedly connected to the upper surface of the base 1. The upper ends of each support rod 2 are fixedly connected together to form a collection box 3. An installation hole is provided on the upper surface of the collection box 3. A mesh conveyor belt 4 is arranged inside the installation hole. A U-shaped plate 5 is fixedly connected to the upper surface of the collection box 3. A sandblasting machine 6 is fixedly connected below the U-shaped plate 5. A discharge port is provided below the collection box 3. A discharge pipe 7 is fixedly connected inside the discharge port. Strip-shaped holes are provided on both sides of the discharge pipe 7. A filter screen 8 is slidably arranged inside the two strip-shaped holes. Screening mechanisms are provided at both ends of the filter screen 8. The filter screen 8 moves through the screening mechanisms.

[0025] Place the plastic cover plate of the washing machine on the upper surface of the mesh conveyor belt 4. Then, use the sandblasting machine 6 to spray quartz sand to remove burrs on its surface. Then, the quartz sand and burrs fall into the interior of the collection box 3 together. Finally, the quartz sand can be filtered out through the filter screen 8 to facilitate its addition to the sandblasting machine again, thereby preventing waste of quartz sand and reducing costs.

[0026] In order to improve the filtering effect, as Figures 1-2As shown in the figure, the sieve moving mechanism includes a mounting plate 9, a motor 10, an eccentric wheel 11, two connecting rods 12, a push plate 13, two springs 14 and two fixing blocks 15. The mounting plate 9 is fixedly connected to the side wall of the collection box 3. The motor 10 is fixedly connected to the lower surface of the mounting plate 9. The eccentric wheel 11 is fixedly sleeved on the output end of the motor 10. One side of the discharge pipe 7 is fixedly connected to both of the two connecting rods 12. The push plate 13 is slidably sleeved on the outer surfaces of the two connecting rods 12. The two fixing blocks 15 are respectively fixedly connected to one end of the corresponding connecting rod 12. The two springs 14 are respectively slidably sleeved on the rod walls of the corresponding connecting rods 12. Both ends of the filter screen 8 are in contact with the push plate 13 and the eccentric wheel 11 respectively.

[0027] Start the motor 10 to rotate the eccentric wheel 11. Subsequently, the eccentric wheel 11 squeezes the filter screen 8 to move. During this process, the resilience of the two springs 14 can be used to reset the filter screen 8. By repeating this process, the filter screen 8 can move left and right, preventing the quartz sand from accumulating, thereby improving the filtering effect.

[0028] And in order to facilitate the sliding of the quartz sand, as Figures 1-2 shown, the lower end of the collection box 3 is in an inverted cone shape.

[0029] The inverted cone-shaped collection box 3 can make it more convenient for the quartz sand to slide down.

[0030] And in order to facilitate the removal of burrs, as Figure 1 shown, a waste opening is provided at one end of the discharge pipe 7, and a cover plate 16 is hinged inside the waste opening.

[0031] Open the cover plate 16, and then it is convenient to remove the burrs.

[0032] Finally, in order to prevent the quartz sand from spraying out, as Figure 2 shown, sand blocking curtains 17 are fixedly connected to both ends of the U-shaped plate 5.

[0033] The two sand blocking curtains 17 can prevent too much quartz sand from being discharged from both ends of the U-shaped plate 5.

[0034] Only some exemplary embodiments of the present invention are described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above-mentioned drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
