Description

Technical Field

[0001] This invention belongs to the field of plastic pallet cutting and processing technology, specifically a plastic pallet cutting and processing equipment. Background Technology

[0002] Plastic pallets are flat load-bearing components made from plastic as raw material through molding processes such as injection molding, blow molding, and vacuum forming. Their core function is to provide standardized load-bearing, stacking, and handling benchmarks for goods. They widely replace traditional wooden and metal pallets and are core supporting equipment in modern logistics, warehousing, and production.

[0003] Plastic pallet cutting and processing is the core post-processing step in pallet production. Through precise cutting and defect correction, semi-finished products are transformed into qualified finished products. The core focuses on three main goals: correcting process defects, achieving dimensional standardization, and adapting to scenario requirements. It is compatible with three mainstream types of plastic pallets: injection molded, blow molded, and vacuum formed. It is a key link to ensure the versatility, safety, and service life of pallets.

[0004] Under current technological conditions, since most plastic pallets are made of thermoplastic materials, heat is inevitably generated at the cut point where the cutting blade contacts the plastic pallet during the cutting process. This heat may cause the plastic to soften or even melt, causing the molten plastic to adhere to the cut edge before it has completely cooled, thus forming molten burrs. These burrs not only require additional processing in subsequent operations but also inevitably waste some production and processing time.

[0017] The beneficial effects of this invention are as follows: 1. The plastic pallet cutting and processing equipment of the present invention, when cutting plastic pallets with cutting blades, the dust collection component and the grinding component work together to simultaneously cut the plastic pallet and grind off the cut edges to remove burrs. This saves the need for additional processing steps in subsequent operations, saves production and processing time, improves the efficiency of plastic pallet production, and is more conducive to the cutting operation of plastic pallets. Furthermore, the setting of two sets of cutting blades allows for simultaneous operation on both sides of the plastic pallet during cutting and grinding, which can speed up the cutting process.

[0018] 2. The plastic pallet cutting and processing equipment of the present invention, through the continuous downward movement of the cutting blade, the outer wall of the grinding shaft will be moved by the limitation of the plastic pallet, and the grinding shaft will push the push plate to squeeze the return spring in the grinding box, and the grinding shaft will retract into the grinding box. With the push of the return spring, the outer wall of the grinding shaft will grind and cut the cut of the plastic pallet by rotation. By pushing the grinding shaft to grind the cut of the plastic pallet by the return spring, the grinding shaft can grind the upper and lower sides of the cut, avoiding the presence of burrs that are not flush with the cut, and allowing the grinding shaft to perform better grinding of the burrs at the cut.

[0019] 3. The plastic pallet cutting and processing equipment of the present invention uses a suction device to extract air from the suction channel. The suction device then performs slag extraction on the upper and lower sides of the grinding shaft through two suction channels, thereby extracting the burrs ground by the rotation of the grinding shaft. Finally, the burrs are blocked by the filter plate and placed in the grinding box, preventing the ground burrs from being placed in the working environment, which would not only pollute the working environment but also have a certain impact on the cutting operation of plastic pallets.

[0020] 4. The plastic pallet cutting and processing equipment of the present invention, when the scraping plate operation ends, the top of the baffle will be unrestricted by the scraping plate reset, and the return plate spring will push the baffle to reset and rotate through elasticity. The baffle will block the slag storage box and the suction channel, which can prevent the suction device from sucking up the slag in the slag storage box together when it is sucking up the slag, thus affecting the overall suction effect of the suction device.

[0021] 5. The plastic pallet cutting and processing equipment of the present invention, when the cutting blade moves down to cut the plastic pallet, the connecting plate on the grinding box will move down together with the pressure block through the elastic support of the pressure spring as the cutting blade continues to move down. When the bottom of the pressure block contacts the top of the plastic pallet, the pressure block and the support block will clamp the plastic pallet together, thereby making the cutting blade more stable when cutting the plastic pallet and preventing the plastic pallet from moving during the cutting process.

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] like Figures 1 to 9 As shown in the figure, a plastic pallet cutting and processing equipment according to an embodiment of the present invention includes a base plate 1. A suction device 301 is provided at the top center of the base plate 1. A frame plate 2 is fixedly installed on the top of the base plate 1 and is placed outside the suction device 301. The suction device 301 is used to place and fix the plastic pallet. Two grinding boxes 5 are symmetrically arranged at the bottom of the frame plate 2. The two grinding boxes 5 are respectively arranged on one side of the suction device 301. A cutting blade 7 is fixedly installed at the bottom of each of the two grinding boxes 5. A grinding assembly is provided inside each of the two grinding boxes 5. The grinding assembly includes a grinding shaft 9. The grinding assembly is used to drive the grinding shaft 9 to grind the burrs at the cut of the plastic pallet. A dust collection assembly is provided on the inner wall of the grinding box 5. The dust collection assembly is used to pull and collect the burrs ground by the grinding assembly. Because heat is inevitably generated at the cut where the cutting blade contacts the plastic tray, this heat may cause the plastic to soften or even melt. This causes the molten plastic to adhere to the cut edge before it has completely cooled down, thus forming molten burrs. These burrs not only require additional processing in subsequent operations, but also inevitably waste some production and processing time. Before use, a mechanical feeding arm is installed on the outside of this device. When it is necessary to cut the plastic pallet, the mechanical feeding arm is driven to place the plastic pallet in the center on top of the suction device 301. The suction device 301 will then adsorb and fix the plastic pallet. After the plastic pallet is placed, the grinding box 5 can be pushed to the side of the plastic pallet where it needs to be cut. When the grinding box 5 is above the cutting position of the plastic pallet, by pushing the grinding box 5 downward, the grinding box 5 will drive the bottom cutting blade 7 to move downward. The cutting blade 7 will then move to cut the side of the plastic pallet, thereby realizing the cutting operation of the side of the plastic pallet. When the cutting blade 7 is cutting the side of the plastic pallet, the grinding component inside the grinding box 5 is driven to work. The grinding component will drive the grinding shaft 9 to grind the cut edge of the plastic pallet, grinding away the burrs generated during cutting. At the same time, the dust collection component inside the grinding box 5 will also work, collecting dust. The burrs produced by the grinding components are collected and extracted to prevent them from remaining in the device and affecting the cutting operation of the plastic pallet. This also protects the working environment during operation. The two work together to allow the device to grind and remove burrs from the cut edges of the plastic pallet while cutting it, saving the need for additional processing steps in subsequent operations, saving production time, improving the efficiency of plastic pallet production, and facilitating the cutting operation. With the setting of two grinding boxes 5, the device can simultaneously cut and grind both sides of the plastic pallet when cutting and grinding, which can speed up the cutting process. It should be noted that the plastic pallets cut by this device are rectangular pallets. The suction device 301 can be a vacuum adsorption device, composed of an electric pump and suction cups, etc. It is mainly used to adsorb and fix the plastic pallet. This is an existing technical solution, so it is only described in this solution and the specific structure is not shown.

[0027] like Figures 4 to 8 As shown, the grinding assembly also includes a shaft 906, a grinding shaft 9 fixedly installed on the outside of the shaft 906, and rotary cylinders 901 fixedly installed at both ends of the shaft 906. The outer wall of the shaft 906 is movably connected to the inner wall of the grinding box 5. Grooves are symmetrically fixedly installed on the outer wall of the grinding box 5. A displacement block 902 is provided inside each of the two grooves. The outer walls of the two rotary cylinders 901 are fixedly connected to one side of the two displacement blocks 902 respectively. When it is necessary to grind the cut edges of the plastic pallet, the operation is carried out by the rotary cylinder 901 on the drive displacement block 902. The displacement block 902 will drive the shaft 906 to rotate. When the shaft 906 rotates, it will drive the grinding shaft 9 to rotate. The cutting tool 7 moves down to cut the plastic pallet. The grinding shaft 9 will then rotate and grind the cut edge of the cutting tool 7, thereby grinding and eliminating the burrs generated at the cut edge. It should be noted that the grinding shaft 9 should be made of nylon or cotton cloth.

[0028] like Figures 7 to 8 As shown, a push plate 904 is slidably connected to the inner wall of the grinding box 5. A pull rod 903 is symmetrically fixedly installed on the outer wall of the push plate 904. The inner walls of the two pull rods 903 are rotatably connected to the outer wall of the shaft 906. A return spring 905 is symmetrically arranged between one side of the push plate 904 and the inner wall of the grinding box 5. The outer walls of the two shift blocks 902 are slidably connected to the inner walls of the two slot blocks respectively. The grinding shaft 9 can be placed above the side of the cutting tool 7. The outer wall of the grinding shaft 9 can be in close contact with the outer wall of the plastic tray. When the cutting blade 7 moves downward to cut the plastic tray, the grinding shaft 9 is positioned above and to the side of the cutting blade 7 by the elastic push of the return spring 905. As the cutting blade 7 moves downward to cut, the grinding shaft 9 rotates and moves downward along the top of the plastic tray, grinding the plastic tray to the side and upward. Subsequently, as the cutting blade 7 continues to move downward, the outer wall of the grinding shaft 9 is limited by the plastic tray and moves. The grinding shaft 9 then pushes the push plate 904 within the grinding box 5 via the pull rod 903, and the push plate 904 compresses the return spring 905 within the grinding box 5. When the grinding shaft 9 moves inside, it retracts into the grinding box 5. One side of the outer wall of the grinding shaft 9 becomes flush with the position of the cutting tool 7. With the push of the return spring 905, the outer wall of the grinding shaft 9 rotates to grind and cut the cut of the plastic tray. The return spring 905 pushes the grinding shaft 9 to grind the cut of the plastic tray, which allows the grinding shaft 9 to grind the upper and lower sides of the cut, avoiding burrs that are not flush with the cut. This allows the grinding shaft 9 to perform better grinding of burrs at the cut, thus achieving the function of grinding the upper and lower sides of the cut.

[0029] like Figures 7 to 9As shown, the dust collection assembly includes a suction device 11, which is fixedly installed on one side of the outer wall of the grinding box 5. The inner wall of the grinding box 5 is symmetrically provided with suction channels 14. The grinding shaft 9 is placed between the two suction channels 14. Filter plates 1102 are symmetrically fixedly installed on the inner wall of the grinding box 5. Air extraction pipes 1101 are fixedly installed between the two filter plates 1102 and the suction device 11. The positions of the two filter plates 1102 correspond to the positions of the extraction ports of the two suction channels 14. When the grinding shaft 9 rotates to grind the cut edge of the plastic pallet, the suction device 11 is driven to operate. The suction device 11 will draw air into the suction channel 14 through the air extraction chamber 1101. The suction device 11 will then perform slag extraction on the grinding shaft 9 from both the upper and lower sides through the two suction channels 14, thereby extracting the burrs ground by the rotation of the grinding shaft 9. Finally, the burrs are blocked by the filter plate 1102 and placed in the grinding box 5 to prevent the ground burrs from being placed in the working environment, which would pollute the working environment and affect the cutting operation of the plastic pallet. It plays the role of absorbing and collecting burrs. It should be noted that the suction device 11 may be composed of a suction pump and an air storage tank, etc. It is mainly used to extract the ground burrs. It is existing technology, so it is only described in this solution. The specific structure is not shown. Moreover, the extraction intensity of the suction device 11 needs to be set according to the actual working scenario.

[0030] like Figures 7 to 9 As shown, telescopic cylinders 13 are symmetrically fixedly installed on the top of the grinding box 5, and scraper plates 1301 are fixedly installed on the output ends of the two telescopic cylinders 13. A slag storage box 12 is fixedly installed on the bottom of the grinding box 5. Two suction channels 14 are connected to the slag storage box 12. The scraping end of the scraper plate 1301 can slide and connect with the outer wall of the two filter plates 1102. When the grinding shaft 9 finishes grinding the cut of the plastic tray, the telescopic cylinder 13 will drive the scraper plate 1301 to extend and move downward. The scraper of the scraper plate 1301 will scrape the outer wall of the filter plate 1102 by moving downward. The scraper plate 1301 will scrape and press the burrs adsorbed on the two filter plates 1102 downward, thereby scraping and pressing the burrs into the slag storage box 12. This prevents the burr residue on the filter plate 1102 from affecting the subsequent suction operation of the suction device 11 to suck up the ground burrs, and plays the role of cleaning the filter plate 1102.

[0031] like Figures 7 to 9 As shown, a baffle 1202 is rotatably connected to the inner wall of the slag storage box 12. The baffle 1202 is placed between the suction channel 14 and the slag storage box 12. A return plate spring 1201 is provided between the bottom of the baffle 1202 and the inner wall of the slag storage box 12. The bottom of the scraping plate 1301 can be slidably connected to the outer wall of the baffle 1202. When the scraper plate 1301 scrapes the burr residue on the filter plate 1102 and moves it downward, the scraper plate 1301 will push the baffle 1202. The baffle 1202 will then be pushed and squeezed to open the return spring 1201 inside the slag storage box 12, so that the slag storage box 12 and the suction channel 14 are in a connected state. The scraper plate 1301 will then press the burr residue into the slag storage box 12 for storage. When the scraper plate 1301 finishes its operation, the top of the baffle 1202 will be unrestricted by the scraper plate 1301 returning to its original position. The return spring 1201 will then push the baffle 1202 to return to its original position and rotate. The baffle 1202 will then block the slag storage box 12 and the suction channel 14. The purpose of this setting is to prevent the suction device 11 from sucking up the burr residue in the slag storage box 12 along with the burr residue when it is sucking up the burr residue, thus affecting the overall suction effect of the suction device 11.

[0032] like Figures 2 to 5 As shown, guide rails 201 are symmetrically fixedly installed on the bottom inner wall of the frame plate 2. Electric sliders 202 are symmetrically slidably connected inside the two guide rails 201. Shift plates 8 are fixedly installed between each pair of the bottom of the four guide rails 201. Limiting rods 801 are symmetrically fixedly installed on the bottom of each of the two shift plates 8. The bottom ends of the four limiting rods 801 are slidably connected to the top of the base plate 1. Sliding blocks 501 are symmetrically fixedly installed on the outer walls of the two grinding boxes 5. The inner walls of the four sliding blocks 501 are slidably connected to the outer walls of the four limiting rods 801 respectively. Hydraulic rods 10 are fixedly installed between the top of the two grinding boxes 5 and the bottom of the two shift plates 8. When the side of a plastic pallet needs to be cut, the electric slider 202 is driven to move inside the frame plate 2. The electric slider 202 then moves the grinding box 5 laterally via the shift plate 8, causing the grinding box 5 to move above the cutting side of the plastic pallet. When the grinding box 5 reaches the cutting position of the plastic pallet, the electric slider 202 is stopped from moving further. Then, the hydraulic rod 10 is driven to work. The hydraulic rod 10 moves downward via the grinding box 5, and the sliding block 501 slides on the shift plate 8, causing the cutting blade 7 to move downward to cut the side of the plastic pallet. This provides power and position adjustment for the cutting blade 7. By using the electric slider 202 to drive the grinding box 5 to make lateral adjustments on the side of the plastic pallet, this device can cut plastic pallets of different sizes and specifications, increasing the applicability of this device during cutting.

[0033] like Figures 3 to 4As shown, waste bins 4 are fixedly installed on the outer walls of the four limiting rods 801 in pairs. Support blocks 401 are fixedly installed on the top of each of the two waste bins 4. The top of each of the two support blocks 401 can fit and contact the bottom of the plastic tray. The waste bins 4 are placed below the cutting blade 7, and the support blocks 401 are placed on the side and below the cutting blade 7. When the grinding box 5 moves toward the side cut of the plastic pallet, the shifting plate 8 will move the waste bin 4 together. When the grinding box 5 moves to the side cut of the plastic pallet, the shifting plate 8 will stop moving the waste bin 4. The waste bin 4 will then move the support block 401 to the bottom of the plastic pallet to support the side of the plastic pallet. This prevents the plastic pallet from tipping over on top of the suction device 301 due to excessive cutting pressure when the cutting blade 7 is cutting the plastic pallet. At the same time, when the cutting blade 7 cuts the plastic pallet, the cut waste will fall downwards by gravity and eventually be placed in the waste bin 4 for waste collection and storage, thus serving as a waste storage device.

[0034] like Figures 4 to 5 As shown, connecting plates 601 are fixedly installed on the outer walls of both grinding boxes 5, and pressure blocks 6 are slidably connected to the inner walls of both connecting plates 601. Pressure springs 602 are provided between the top of the two pressure blocks 6 and the bottom of the two connecting plates 601. The bottom of the two pressure blocks 6 can fit in contact with the top of the plastic tray. The two pressure blocks 6 are respectively placed directly above the two support blocks 401. When the cutting blade 7 moves down to cut the plastic pallet, the connecting plate 601 on the grinding box 5 will move down together with the pressure block 6 through the elastic support of the pressure spring 602. When the bottom of the pressure block 6 contacts the top of the plastic pallet, the pressure block 6 and the support block 401 will clamp the plastic pallet together, so that the cutting blade 7 is more stable when cutting the plastic pallet, preventing the plastic pallet from moving during the cutting process, and playing the role of limiting the position of the plastic pallet.

[0035] like Figures 1 to 2 As shown, a material transfer motor 3 and a support frame 302 are fixedly installed at the top center of the base plate 1. The support frame 302 is mounted on the outside of the material transfer motor 3. The output end of the material transfer motor 3 passes through the inner wall of the support frame 302 and is fixedly connected to the bottom of the suction device 301. The bottom of the suction device 301 is slidably connected to the top of the support frame 302. When the cutting blade 7 finishes cutting the side of the plastic pallet, the rotating motor 3 is driven to operate. The rotating motor 3 will drive the suction device 301 to rotate 90 degrees on the top of the support frame 302. This will cause the suction device 301 to rotate the plastic pallet on the top of the support frame 302. The suction device 301 will then cause the plastic pallet to change side position, so that the two cutting blades 7 can cut the other two sides of the plastic pallet, thus alternating the cutting position of the plastic pallet's side.

[0036] Working Principle: Before use, a mechanical feeding arm is installed on the outside of this device. When it is necessary to cut the plastic pallet, the mechanical feeding arm is driven to place the plastic pallet in the center on top of the suction device 301. The suction device 301 will then adsorb and fix the plastic pallet. After the plastic pallet is placed, the grinding box 5 can be pushed to the side of the plastic pallet where it needs to be cut. When the grinding box 5 is above the cutting position of the plastic pallet, pushing the grinding box 5 downward will drive the cutting blade 7 at the bottom to move downward. The cutting blade 7 will then move to cut the side of the plastic pallet, thereby realizing the cutting operation of the side of the plastic pallet. When the cutting blade 7 is cutting the side of the plastic pallet, the grinding component inside the grinding box 5 is driven to work. The grinding component will drive the grinding shaft 9 to cut the plastic pallet. The cutting edge is ground to remove burrs generated during cutting. At the same time, the dust collection component in the grinding box 5 also works, collecting and absorbing the burrs ground down by the grinding component to prevent them from remaining in the device and affecting the cutting operation of the plastic pallet. This also protects the working environment during operation. The two work together to allow the device to grind and remove burrs from the cutting edge of the plastic pallet while cutting it, saving the need for additional processing steps in subsequent operations, saving production and processing time, improving the efficiency of plastic pallet production, and making it more convenient for cutting plastic pallets. With the setting of two sets of grinding boxes 5, when cutting and grinding plastic pallets, the device can cut and grind both sides of the plastic pallet at the same time, which can speed up the cutting process. When it is necessary to grind the cut edge of the plastic pallet, the operation is carried out by the rotary cylinder 901 on the drive displacement block 902. The displacement block 902 will drive the shaft 906 to rotate. When the shaft 906 rotates, it will drive the grinding shaft 9 to rotate. The cutting tool 7 moves down to cut the plastic pallet. The grinding shaft 9 will rotate and grind the cut edge cut by the cutting tool 7, thereby grinding and eliminating the burrs generated at the cut edge, thus achieving the function of grinding the cut edge burrs. When the cutting blade 7 moves downward to cut the plastic tray, the grinding shaft 9 is positioned above and to the side of the cutting blade 7 by the elastic push of the return spring 905. As the cutting blade 7 moves downward to cut, the grinding shaft 9 rotates and moves downward along the top of the plastic tray, grinding the plastic tray to the side and upward. Subsequently, as the cutting blade 7 continues to move downward, the outer wall of the grinding shaft 9 is limited by the plastic tray and moves. The grinding shaft 9 then pushes the push plate 904 within the grinding box 5 via the pull rod 903, and the push plate 904 compresses the return spring 905 within the grinding box 5. When the grinding shaft 9 moves inside, it will retract into the grinding box 5. One side of the outer wall of the grinding shaft 9 will be flush with the position of the cutting tool 7. With the push of the return spring 905, the outer wall of the grinding shaft 9 will rotate to grind and cut the cut of the plastic tray. The return spring 905 pushes the grinding shaft 9 to grind the cut of the plastic tray, which can grind the upper and lower sides of the cut, avoiding the presence of burrs that are not flush with the cut. This allows the grinding shaft 9 to perform better grinding of the burrs at the cut, thus achieving the function of grinding the upper and lower sides of the cut. When the grinding shaft 9 rotates to grind the cut edge of the plastic pallet, the suction device 11 is driven to operate. The suction device 11 will draw air into the suction channel 14 through the air extraction chamber pipe 1101. The suction device 11 will then perform slag extraction operation on the upper and lower sides of the grinding shaft 9 through the two suction channels 14, thereby extracting the burrs ground by the rotation of the grinding shaft 9. Finally, the slag is blocked by the filter plate 1102 and placed in the grinding box 5 to prevent the ground burrs from being placed in the working environment, which would pollute the working environment and have a certain impact on the cutting operation of the plastic pallet. This plays the role of absorbing and collecting burrs. When the grinding shaft 9 finishes grinding the cut of the plastic tray, the telescopic cylinder 13 will drive the scraper plate 1301 to extend and move downward. The scraper of the scraper plate 1301 will scrape the outer wall of the filter plate 1102 by moving downward. The scraper plate 1301 will scrape and press the burrs adsorbed on the two filter plates 1102 downward, thereby scraping and pressing the burrs into the slag storage box 12. This prevents the burr residue on the filter plate 1102 from affecting the subsequent suction operation of the suction device 11 to suction the ground burrs, and plays the role of cleaning the filter plate 1102. When the scraper plate 1301 scrapes the burr residue on the filter plate 1102 and moves it downward, the scraper plate 1301 will push the baffle 1202. The baffle 1202 will be pushed and squeezed to open the return spring 1201 inside the slag storage box 12, so that the slag storage box 12 and the suction channel 14 are in a connected state. The scraper plate 1301 will then push the burr residue into the slag storage box 12 for storage. When the scraper plate 1301 finishes its operation, the top of the baffle 1202 will be unrestricted by the scraper plate 1301 returning to its original position. The return spring 1201 will then push the baffle 1202 to return to its original position and rotate. The baffle 1202 will then block the slag storage box 12 and the suction channel 14. The purpose of this setting is to prevent the suction device 11 from sucking up the burr residue in the slag storage box 12 along with it when it is sucking up the burr residue, thus affecting the overall suction effect of the suction device 11. When the side of a plastic pallet needs to be cut, the electric slider 202 is driven to move inside the frame plate 2. The electric slider 202 then moves the grinding box 5 laterally through the shift plate 8, causing the grinding box 5 to move above the cutting side of the plastic pallet. When the grinding box 5 moves to the cutting position of the plastic pallet, the electric slider 202 is stopped from moving further. Then the hydraulic rod 10 can be driven to work. The hydraulic rod 10 moves downward through the grinding box 5, and the sliding block 501 slides on the shift plate 8, causing the cutting blade 7 to move downward to cut the side of the plastic pallet. This provides power and position adjustment for the cutting blade 7. By using the electric slider 202 to drive the grinding box 5 to make lateral adjustments on the side of the plastic pallet, this device can cut plastic pallets of different sizes and specifications, increasing the applicability of this device during cutting. When the grinding box 5 moves toward the side cut of the plastic pallet, the shifting plate 8 will move the waste bin 4 together. When the grinding box 5 moves to the side cut of the plastic pallet, the shifting plate 8 will stop moving the waste bin 4. The waste bin 4 will then move the support block 401 to the bottom of the plastic pallet to support the side of the plastic pallet. This prevents the plastic pallet from tipping over on top of the suction device 301 due to excessive cutting pressure when the cutting blade 7 is cutting the plastic pallet. At the same time, when the cutting blade 7 is cutting the plastic pallet, the cut waste will fall downwards by gravity and eventually be placed in the waste bin 4 for waste collection and storage, thus serving as a waste storage device. When the cutting blade 7 moves down to cut the plastic pallet, the connecting plate 601 on the grinding box 5 will move down together with the pressure block 6 through the elastic support of the pressure spring 602. When the bottom of the pressure block 6 contacts the top of the plastic pallet, the pressure block 6 and the support block 401 will clamp the plastic pallet together, so that the cutting blade 7 is more stable when cutting the plastic pallet, preventing the plastic pallet from moving during the cutting process, and playing the role of limiting the position of the plastic pallet. When the cutting blade 7 finishes cutting the side of the plastic pallet, the rotating motor 3 is driven to operate. The rotating motor 3 will drive the suction device 301 to rotate 90 degrees on the top of the support frame 302. This will cause the suction device 301 to rotate the plastic pallet on the top of the support frame 302. The suction device 301 will then cause the plastic pallet to change side position, so that the two cutting blades 7 can cut the other two sides of the plastic pallet, thus alternating the cutting position of the plastic pallet's side.
