[0002] Plastic pallets, also known as plastic pallets, are made of thermoplastic plastics such as PE and PP, plus some additives to improve performance, through injection molding, blow molding and other processes.

[0013] Furthermore, a method for using a plastic pallet leveling device comprises the following steps:

[0014] S1: When in use, the injection-molded plastic pallet is placed on the base through the robotic arm. When the plastic pallet falls on the base, the base moves downward due to its own weight, and finally drives the clamping plate to fix the pallet;

[0015] S2: Start the motor. When the motor is working, it will drive the bidirectional threaded rod to rotate, and drive the sliding column to move through the rectangular block. The sliding column drives the rotating plate to push the cleaning block to clean the tray;

[0016] S3: When the bidirectional threaded rod drives the rectangular block to move, it also drives the U-shaped fixed plate to move, thereby pulling the pull plate to generate suction and collect the burrs during the cleaning process;

[0017] S4: When the cleaning is completed, the bidirectional threaded rod drives the rectangular block back to its original position, thereby pushing the pull plate to discharge the burrs inside the collection box through the discharge pipe.

[0018] The present invention has the following beneficial effects:

[0019] (1) In the present invention, the motor is started. When the motor is working, it drives the bidirectional threaded rod to rotate. When the bidirectional threaded rod rotates, it drives the rectangular block to move horizontally and drives the sliding column to move together. When the sliding column moves, it pushes the rotating plate to make the circular shaft of the side wall of the moving block move along the slide groove. Since the slide groove is arranged in an arc shape, the sliding column will drive the rotating plate to rotate a short distance after starting, thereby driving the circular shaft to move along the slide groove. When the sliding column approaches the base, the rotating plate drives the circular shaft to move horizontally, and the cleaning block between the rotating plates will contact the outer surface of the plastic pallet. Along with the movement of the sliding column, the cleaning block is pushed to clean the surface of the plastic pallet. When the pallet is shaped by the mold processing, burrs may be generated. By setting a cleaning mechanism, the burrs on the pallet can be quickly and effectively removed, thereby improving the appearance quality of the product, reducing impurities and residues on the surface of the pallet, reducing the wear of the pallet, and thus extending the service life of the pallet.

[0020] (2) In the present invention, the bidirectional threaded rod drives the rectangular block to move together with the U-shaped fixed plate, and then drives the pull plate to move outward. When the pull plate moves outward, suction is generated, and the suction enters the cavity of the cleaning block along the extraction tube, and collects the burrs that fall after cleaning through the extraction port, and finally enters the interior of the collection box along the extraction tube. After cleaning, the rectangular block moves inward and drives the U-shaped fixed plate to move together, thereby pushing the pull plate to move inward, squeezing the burrs inside the collection box and discharging them through the discharge pipe. By collecting the burrs, the smoothness of the pallet surface can be ensured, quality problems caused by burrs can be reduced, and the burrs that fall after cleaning can be prevented from adhering to the pallet again in the subsequent production process.

[0021] (3) According to the present invention, when the plastic tray falls on the base, the base will move downward due to its own weight. When the base moves downward, it will drive the circular ring to move downward and drive the sliding rod to move downward together. When the sliding rod moves downward, it will drive the arc block to move downward. Since the arc block is in contact with the conical fixed column, the arc block will move along the surface of the conical fixed column and move outward along with the downward movement of the circular ring. When the arc block moves, it will push the sliding rod to move outward and drive the fixed plate to move together. When the fixed plate moves outward, it will push the rotating rod to rotate, thereby pushing the sliding block to move upward along the slide groove and pushing the push plate to rotate. The trapezoidal block pushes the clamping plate to move inward together to fix the plastic tray, thereby preventing the plastic tray from being affected by the impact force generated by the cleaning block when cleaning the plastic tray during the leveling and cleaning process, thereby causing the plastic tray to be displaced or tilted, thereby affecting the cleaning and leveling of the plastic tray.

[0022] (4) In the present invention, when the clamping plate clamps the plastic pallet, the hollow block will contact the plastic pallet. When the hollow block and the plastic pallet are in contact, along with the movement of the clamping plate, the movable plate will be pushed by the top block to move inward inside the airbag. When the top block pushes the movable plate to move, it will squeeze the gas inside the hollow block. The squeezed gas will enter the airbag along the connecting pipe to expand the airbag and contact the plastic pallet. When the cleaning mechanism cleans the plastic pallet, the cleaning block will generate an impact force during the cleaning process, thereby causing the plastic pallet to shake during the cleaning process. When the plastic pallet shakes, it will squeeze the airbag and the hollow block, and cause the hollow block to move slightly outward. When the hollow block moves, it will push the connecting rod to move to both sides, thereby pushing the movable block, and buffering through the spring to reduce the impact of the shaking of the plastic pallet. By reducing the shaking, the buffer mechanism can reduce the impact and wear of the pallet during the cleaning process, thereby extending the service life of the pallet.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] A method for using a plastic pallet leveling device comprises the following steps:

[0046] S1: When in use, the injection-molded plastic pallet is placed on the base 401 by the robotic arm. When the plastic pallet falls on the base 401, the base 401 moves downward due to its own weight, and finally drives the clamping plate to fix the pallet;

[0047] S2: Start the motor 201. When working, the motor 201 drives the bidirectional threaded rod 202 to rotate, and drives the sliding column 204 to move through the rectangular block 205. The sliding column 204 drives the rotating plate 206 to push the cleaning block 207 to clean the tray;

[0048] S3: When the bidirectional threaded rod 202 drives the rectangular block 205 to move, it also drives the U-shaped fixing plate 303 to move, thereby pulling the pulling plate 302 to generate suction, and the burrs are collected during the cleaning process;

[0049] S4: When the cleaning is completed, the bidirectional threaded rod 202 drives the rectangular block 205 back to its original position, thereby pushing the pull plate 302 to discharge the burrs inside the collection box 301 through the discharge pipe 305.

[0050] When in use, the molded plastic tray is placed on the base 401 through the robotic arm. When the plastic tray falls on the base 401, the base 401 moves downward due to its own weight. When the base 401 moves downward, it will drive the ring 402 to move downward, and drive the sliding rod 404 to move downward together. When the sliding rod 404 moves downward, it will drive the arc block 405 to move downward. Since the arc block 405 is in contact with the conical fixing column 403, the arc block 405 moves along the surface of the conical fixing column 403 and moves outward along with the downward movement of the ring 402. When the arc block 405 moves, it will push the sliding rod 404 to move outward and drive the fixing plate 40 6 moves together, when the fixed plate 406 moves outward, it will push the rotating rod 407 to rotate, thereby pushing the sliding block 408 to move upward along the slide groove, and push the push plate 409 to rotate, so as to push the clamping plate 410 to move inward through the trapezoidal block to fix the plastic tray, start the motor 201, when the motor 201 is working, it will drive the two-way threaded rod 202 to rotate, when the two-way threaded rod 202 rotates, it will drive the rectangular block 205 to move horizontally, and drive the sliding column 204 to move together, and when the sliding column 204 moves, it will push the rotating plate 206 to make the circular axis of the side wall of the rotating plate 206 move along the slide groove. The sliding column 204 is arranged in a certain position, so the sliding column 204 will drive the rotating plate 206 to rotate after a short distance of starting, thereby driving the round shaft to move along the slide groove. When the sliding column 204 is close to the base 401, the rotating plate 206 drives the round shaft to move horizontally, and the cleaning block 207 between the rotating plates 206 will contact the outer surface of the plastic tray. With the movement of the sliding column 204, the cleaning block 207 is pushed to clean the surface of the plastic tray. The bidirectional threaded rod 202 drives the rectangular block 205 to move, and the U-shaped fixed plate 303 is driven to move together, and the pull plate 302 is driven to move outward together. When the pull plate 302 moves outward, suction is generated, and the suction is drawn along the extraction The tube 304 enters the cavity of the cleaning block 207, and collects the burrs that fall after cleaning through the extraction port, and finally enters the interior of the collection box 301 along the extraction tube 304. When cleaning is completed, the rectangular block 205 will move inward and drive the U-shaped fixed plate 303 to move together, thereby pushing the pull plate 302 to move inward, squeezing the burrs inside the collection box 301, and discharging them through the discharge tube 305. When the clamping plate 410 clamps the plastic pallet, the hollow block 506 will contact the plastic pallet. When the hollow block 506 contacts the plastic pallet, along with the movement of the clamping plate 410, the movable plate 502 will be pushed through the top block 501 to move inward inside the airbag 507.When the top block 501 pushes the movable plate 502 to move, it squeezes the gas inside the hollow block 506. The squeezed gas will enter the airbag 507 along the connecting pipe to expand the airbag 507 and contact the plastic tray. When the cleaning mechanism 2 cleans the plastic tray, the cleaning block 207 will generate impact force in the process of cleaning the plastic tray, causing the plastic tray to shake during the cleaning process. When the plastic tray shakes, it squeezes the airbag 507 and the hollow block 506, and causes the hollow block 506 to move slightly outward. When the hollow block 506 moves, it pushes the connecting rod 505 to move to both sides, thereby pushing the moving block 503 and buffering it through the spring.
