[0060] The operation steps of the aluminum-plastic board burr grinding device of the present utility model are as follows:

[0061] S1. According to the size of the aluminum-plastic board 2 to be ground, start the two electric push rods 31, and drive the two bearing flanges 41 of the extension arm assembly 4 to approach or move away from each other through the electric push rods 31, so as to complete the adjustment of the lengths of the two extension arm assemblies 4, making the length of one extension arm assembly 4 match the length of the aluminum-plastic board 2 (the length of one extension arm assembly 4 is slightly less than the length of the aluminum-plastic board 2), and the length of the other extension arm assembly 4 match the width of the aluminum-plastic board 2 (the length of the other extension arm assembly 4 is slightly less than the width of the aluminum-plastic board 2). Place the aluminum-plastic board 2 on the workbench 3 and straighten the aluminum-plastic board 2, so that the bearing flanges 41 of the two extension arm assemblies 4 respectively support the outer edges of the aluminum-plastic board 2 to be ground (the outer contour line of the aluminum-plastic board 2 extends to the outside of the bearing flanges 41, so as to facilitate the subsequent grinding of the aluminum-plastic board 2).

[0062] S2. The output end of the lifting cylinder 6 extends, and the pressing plate 5 is driven by the lifting cylinder 6 to press against the aluminum-plastic board 2, so as to lock the aluminum-plastic board 2 on the workbench 3.

[0063] S3. Start the distance adjustment cylinder 82, and the distance adjustment cylinder 82 drives the translation seat 7 to move towards the aluminum-plastic board 2. When the translation seat 7 reaches the predetermined position (the grinding disc 9 approaches the aluminum-plastic board 2), turn off the distance adjustment cylinder 82, and by rotating the fine adjustment screw rod 83, make the two grinding discs 9 respectively accurately abut against the burrs on both sides of the aluminum-plastic board 2.

[0064] S4. Start the rotating motor 91, and the rotating motor 91 drives the grinding disc 9 and the brushes 73 to rotate. Start the driving motor, and the driving motor drives the screw rod 72 to rotate. The rotation of the screw rod 72 causes the sliding table 71 to reciprocate in the chute of the translation seat 7. During this process, the two grinding discs 9 respectively grind the burrs on both sides of the aluminum-plastic board 2, and the brushes 73 clean both sides of the aluminum-plastic board 2.

[0065] S5. After the two sides of the aluminum-plastic board 2 are ground, by starting the adjustment motor 13, the adjustment motor 14 drives the workbench 3 and the rotating seat 121 to rotate, so as to adjust the burrs on the other two sides of the aluminum-plastic board 2 to face the direction of the two grinding discs 9.

[0066] S6. Through the two-stage position control of the distance-adjusting cylinder 82 and the fine-adjusting lead screw 83, the two grinding discs 9 are accurately abutted against the other two sides' rough edges of the aluminum-plastic board 2, and continue the above operations to grind the other two sides' rough edges of the aluminum-plastic board.

[0067] As a preferred embodiment, elastic rubber layers 10 are respectively laid on the tabletop of the workbench 3, the top of the bearing flange 41, and the bottom of the extrusion plate 5.

[0068] The aluminum-plastic board rough-edge grinding device of the present utility model is supported on the outer edge of the aluminum-plastic board to be ground through the extension arm assembly. When the aluminum-plastic board rough-edge grinding device grinds aluminum-plastic boards of different sizes, it can avoid the outer edge of the aluminum-plastic board (especially the thinner aluminum-plastic board) from bending and sagging, improve the grinding accuracy, and make the workbench adapt to aluminum-plastic boards of different sizes.

[0069] The aluminum-plastic board rough-edge grinding device of the present utility model performs two-stage position control on the translation seat through the distance-adjusting cylinder and the fine-adjusting lead screw. When adjusting the position of the translation seat, first drive the translation seat to the predetermined position through the distance-adjusting cylinder, and then further fine-tune the position of the translation seat through the fine-adjusting lead screw, so that the two grinding discs are accurately abutted against the opposite sides of the aluminum-plastic board, improve the grinding accuracy, and avoid damaging the aluminum-plastic board caused by the two grinding discs squeezing the aluminum-plastic board. By simultaneously grinding the two sides' rough edges of the aluminum-plastic board with the two grinding discs, the grinding efficiency is improved. When grinding the other two sides' rough edges of the aluminum-plastic board, adjust the motor to drive the workbench to rotate. The workbench drives the aluminum-plastic board, the extrusion plate, and the rotating seat to rotate, so that the other two sides' rough edges of the aluminum-plastic board are aligned with the two grinding discs, thereby quickly and conveniently adjusting the aluminum-plastic board in place and grinding the other two sides' rough edges of the aluminum-plastic board, and further improving the grinding efficiency of the aluminum-plastic board rough-edge grinding device of the present utility model.

[0070] For the aluminum-plastic board rough-edge grinding device of the present utility model, brushes are respectively arranged on both sides of the grinding disc. While the grinding disc grinds the aluminum-plastic board, the rotating brushes clean both sides of the aluminum-plastic board, so that the ground aluminum-plastic board is cleaner and tidier.

[0071] The above description is only the preferred embodiments of the present application and the explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
