It should be understood that the description is only exemplary and is not intended to limit the scope of the present application. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present application.

[0019] As shown in Figure 1 With Figure 2 The present application provides a polarizing plate edge material removal device, which comprises two frames 1 and a belt polishing piece 2 installed between the two frames 1. The belt polishing piece 2 comprises a sand belt 21, a belt roller 22 and a servo motor 23. The two belt rollers 22 are rotatably installed between the two frames 1 from top to bottom. The sand belt 21 is sleeved on the two belt rollers 22. The servo motor 23 is installed on the side surface of the frame 1, and the output end of the servo motor 23 is connected with the shaft of the belt roller 22 located at the upper position.

[0020] In this embodiment, the bottom of the two frames 1 is provided with a collection box 3. The collection box 3 is provided with a collection chamber 4. An opening is formed in the top of the collection box 3 and is in communication with the collection chamber 4. The bottom of the sand belt 21 extends into the opening. The side surface of the collection box 3 is connected with a dust exhaust pipe 5 in communication with the collection chamber 4.

[0021] In this embodiment, a brush dust exhaust assembly 6 is rotatably installed in the collection chamber 4. The belt roller 22 located at the lower position is drivingly connected with the brush dust exhaust assembly 6 through a linkage 7. When the belt roller 22 rotates, the brush dust exhaust assembly 6 is driven to rotate by the linkage 7 to clean the bottom of the sand belt 21. The dust cleaned is exhausted through the dust exhaust pipe 5.

[0022] The brush dust removal assembly 6 comprises a brush 61 and an axial fan blade 62. The brush 61 is horizontally rotatably arranged in the collecting chamber 4. The axial fan blade 62 is arranged at the end of the brush 61 and located in the dust removal pipe 5. The brush 61 comprises a brush rod 611, a brush cylinder 612 and brush hairs 613. The brush rod 611 is horizontally arranged in the collecting chamber 4. One end of the brush rod 611 is rotatably connected to the inner wall of the side of the collecting box 3 away from the dust removal pipe 5. The brush cylinder 612 is fixedly sleeved on the brush rod 611 and located in the collecting chamber 4. The brush hairs 613 are connected to the outer periphery of the brush cylinder 612 and abut against the abrasive belt 21. The axial fan blade 62 is arranged at the other end of the brush rod 611.

[0023] In the embodiment, the linkage 7 comprises two rotating rods 71, two pulleys 72 and a belt 73. One rotating rod 71 is horizontally rotatably connected to the side of the frame 1.

[0024] When the abrasive belt 21 is driven to rotate by the belt roller 22 driven by the servo motor 23, the belt roller 22 located at the lower position is rotated to drive the rotating rod 71 connected thereto to rotate. The rotating rod 71 is connected to the rotating rod 611 through the pulley 72 and the belt 73, so that kinetic energy is transmitted to the rotating rod 611. The brush rod 611 and the brush cylinder 612 are driven to rotate. Since the bottom of the abrasive belt 21 extends into the opening at the top of the collecting box 3, the brush cylinder 612 is rotated to clean the bottom of the abrasive belt 21 by the brush hairs 613 on the brush cylinder 612. The dust cleaned is dropped into the collecting chamber 4. Since the axial fan blade 62 is arranged at the end of the brush cylinder 612 and located in the dust removal pipe 5, the brush rod 611 is rotated to drive the axial fan blade 62 to rotate and generate outward air flow in the dust removal pipe 5, so that the dust in the collecting chamber 4 is discharged along the dust removal pipe 5. The structure utilizes the kinetic energy generated when the abrasive belt 21 rotates and transmits the kinetic energy to the brush dust removal assembly 6 through the linkage 7. The dust on the abrasive belt 21 is directly cleaned by the brush dust removal assembly 6, so that the dust is prevented from adhering to the abrasive belt 21, and the quality of the processed polaroid is ensured.
