Rectangular plastic pipes, as one type of plastic products, need to be cut during processing to ensure that the length of the rectangular plastic pipes meets the use requirements; when the existing plastic product processing device is used, when the rectangular plastic pipes need to be cut, splashing debris will be generated, and these debris may adhere to the surface of the rectangular plastic pipes, affecting the surface quality of the rectangular plastic pipes. In addition, if the debris contains sharp edges or particles, they may also scratch the surface of the rectangular plastic pipes, further reducing the surface quality; Therefore, when the present embodiment is in use, the pipe to be cut is passed through the center of the gear rings 12 on both sides, and the two ends of the rectangular plastic pipe are fixed. After the cutting position is determined, the motors 24 on both sides are started to drive the gears 22 to rotate, and the gears 22 drive the gear rings 12 to rotate, so that the multiple connecting rods 1 26 and 27 can be rotated at the same time, so that the sliding rods 3 21 slide on the fixing ring 11, and the multiple blocking plates 2 20 are simultaneously close to the axis of the gear ring 12 until they fit with the four corners of the rectangular plastic pipe, and the blocking plates 1 19 and the blocking plates 2 20 also slide relative to each other until the rectangular area formed by the blocking plates 1 19 and the blocking plates 2 20 fits with the rectangular plastic pipe. The cross-sectional area of ​​the rectangular plastic pipe is the same. At this time, a fence can be formed on both sides of the rectangular plastic pipe to be cut, and then the electric push rod 3 28 is started to drive the lifting plate 30 to descend, and the blade 33 is rotated under the action of the motor 32 to cut the rectangular plastic pipe. The debris generated during the cutting process will be intercepted by the blocking plate 19 and the blocking plate 20, and the blocking plate 19 and the blocking plate 20 have sufficient thickness to prevent the debris from splashing to the part of the rectangular plastic pipe other than the cutting position, thereby ensuring the surface quality of the rectangular plastic pipe and avoiding the situation where the surface of the rectangular plastic pipe is scratched due to sharp edges or particles contained in the debris; After the rectangular plastic pipe is cut into two parts, the blade 33 is reset. At this time, there are still some debris near the cutting part of the rectangular plastic pipe. The motors 14 on both sides can be started at the same time to rotate the threaded rod 3, so that the frames 12 on both sides slide and move away from each other at the same time. Under the clamping action of the two clamping blocks 10, the two parts of the rectangular plastic pipe can be moved away from each other. When the rectangular plastic pipe moves, its surface will scrape against the edges of the blocking plate 20 and the blocking plate 19, so that the debris attached to the cutting part is scraped off and falls into the collection box 6, so that the debris remaining near the cutting part of the rectangular plastic pipe can be removed, further ensuring the surface quality of the rectangular plastic pipe. After the debris on the surface of the rectangular plastic pipe is scraped off by the blocking plate 20 and the blocking plate 19, the debris may still adhere to the surface of the blocking plate 19 and the blocking plate 20. When the subsequent rectangular plastic pipe is cut, the debris may fall onto the surface of the rectangular plastic pipe. Therefore, after the cut rectangular plastic pipe is taken away from the middle of the gear ring 12, the blocking plate 20 is driven to move again, so that the distance between the end faces of the blocking plates 20 on the front and rear sides is equal to the length of the scraper 2 34, and then the electric push rod 14 is started to drive the scraper 2 34 to descend, and the slide bar 15 slides on the mounting plate 13. When the scraper 2 34 descends, the raised part in the middle will contact the upper and lower sides. The surface of the blocking plate 19 is scraped, and the front and rear sides of the scraper 2 34 will scrape the surface of the blocking plate 20, so that the debris attached to the surfaces of the blocking plate 20 and the upper and lower blocking plates 19 can be scraped off, and then the scraper 2 34 is reset, and the electric push rod 2 16 is used again to drive the scraper 25 to move to scrape off the debris attached to the surfaces of the front and rear blocking plates 19, so that the debris can fall into the collection box 6, thereby realizing the self-cleaning of the debris remaining on the surfaces of the blocking plates 19 and the blocking plates 20, avoiding the situation that the debris falls on the surface of the rectangular plastic pipe again during subsequent use, avoiding the repeated contamination of the debris, and further ensuring the surface quality of the rectangular plastic pipe; Thus, by utilizing the self-scraping polymer anti-splash mechanism, a barrier is formed on both sides of the rectangular plastic pipe where it is to be cut by using the blocking plate 19 and the blocking plate 20 to fit the surface of the rectangular plastic pipe. The debris generated during the cutting process will be intercepted by the blocking plate 19 and the blocking plate 20, and the blocking plate 19 and the blocking plate 20 are of sufficient thickness so that the debris will not splash to the part of the rectangular plastic pipe other than the cutting position, thereby ensuring the surface quality of the rectangular plastic pipe and avoiding the situation where the surface of the rectangular plastic pipe is scratched due to sharp edges or particles in the debris; and, after the rectangular plastic pipe is cut into two pieces, the two pieces of rectangular plastic pipe can be clamped by the two clamping blocks 10 to keep them away from each other. When the rectangular plastic pipe moves, its surface will scrape against the edges of the blocking plate 20 and the blocking plate 19, so that the debris attached to the cutting position is scraped off and falls into the collecting box 6, so as to remove the debris remaining near the cutting position of the rectangular plastic pipe, thereby further ensuring the surface quality of the rectangular plastic pipe; and, by driving the scraper 2 34 and the scraper 1 25 to move respectively, the two can scrape against the surfaces of the blocking plates 19 and the blocking plates 20, thereby realizing self-cleaning of the debris remaining on the surfaces of the blocking plates 19 and the blocking plates 20, thereby avoiding the situation where the debris falls onto the surface of the rectangular plastic pipe again during subsequent use, thereby avoiding repeated contamination of the debris, thereby further ensuring the surface quality of the rectangular plastic pipe.

[0026] Working principle: Make the pipe to be cut pass through the center of the gear rings 12 on both sides, place both ends of the rectangular plastic pipe to be cut between the two clamping blocks 10, and then manually rotate the bidirectional threaded rod 8 to make the clamping blocks 10 on the upper and lower sides slide simultaneously and approach each other, fit with the surface of the rectangular plastic pipe, and fix the rectangular plastic pipe, thereby ensuring the stability of the rectangular plastic pipe during the cutting process and preventing it from shifting. In addition, by simultaneously starting the motors 4 on both sides, the frames 2 on both sides can move in the same direction at the same time, so that the rectangular plastic pipe moves horizontally, and the blade 33 can be aligned with different positions of the rectangular plastic pipe, and then The flexibility of cutting is improved. After the cutting position is determined, the motors 24 on both sides are started to drive the gears 22 to rotate, and the gears 22 drive the gear ring 12 to rotate, so that the multiple connecting rods 1 26 and 27 can be rotated at the same time, so that the slide bar 3 21 slides on the fixed ring 11, and the multiple blocking plates 2 20 are simultaneously close to the axis of the gear ring 12 until they fit with the four corners of the rectangular plastic pipe, and the blocking plate 1 19 and the blocking plate 2 20 also slide relative to each other until the rectangular area formed by the blocking plate 1 19 and the blocking plate 2 20 is the same as the cross-sectional area of ​​the rectangular plastic pipe. At this time, the two sides of the rectangular plastic pipe to be cut can be The fence is formed, and then the electric push rod 3 28 is started to drive the lifting plate 30 to descend, and the blade 33 is rotated under the action of the motor 32 to cut the rectangular plastic pipe. The debris generated during the cutting process will be intercepted by the blocking plate 1 19 and the blocking plate 20, and the blocking plate 1 19 and the blocking plate 20 have sufficient thickness to prevent the debris from splashing to the part of the rectangular plastic pipe other than the cutting position, thereby ensuring the surface quality of the rectangular plastic pipe and avoiding the situation where the surface of the rectangular plastic pipe is scratched due to sharp edges or particles in the debris; when the rectangular plastic pipe is cut into two pieces, the blade 33 Reset. At this time, there are still some debris near the cutting part of the rectangular plastic pipe. The motors 14 on both sides can be started at the same time to rotate the threaded rod 3, so that the frames 12 on both sides slide and move away from each other at the same time. Under the clamping action of the two clamping blocks 10, the two sections of the rectangular plastic pipe can be moved away from each other. When the rectangular plastic pipe moves, its surface will scrape against the edges of the blocking plate 20 and the blocking plate 19, so that the debris attached to the cutting part is scraped off and falls into the collection box 6, so that the debris remaining near the cutting part of the rectangular plastic pipe can be removed, further ensuring the surface quality of the rectangular plastic pipe.After the debris on the surface of the rectangular plastic pipe is scraped off by the blocking plate 20 and the blocking plate 19, the debris may still adhere to the surface of the blocking plate 19 and the blocking plate 20. When the subsequent rectangular plastic pipe is cut, the debris may fall onto the surface of the rectangular plastic pipe. Therefore, after the cut rectangular plastic pipe is taken away from the middle of the gear ring 12, the blocking plate 20 is driven to move again, so that the distance between the end faces of the blocking plates 20 on the front and rear sides that are away from each other is equal to the length of the scraper 2 34, and then the electric push rod 14 is started to drive the scraper 2 34 to descend, and the slide bar 15 slides on the mounting plate 13. When the scraper 2 34 descends, the raised part in the middle thereof will contact the surface of the blocking plates 19 on the upper and lower sides. The scraper 25 is moved by the electric push rod 16 to scrape off the debris attached to the surfaces of the front and rear blocking plates 19, and the debris can fall into the collection box 6, thereby realizing the self-cleaning of the debris remaining on the surfaces of the blocking plates 19 and 20, avoiding the situation that the debris falls on the surface of the rectangular plastic pipe again during subsequent use, avoiding the repeated contamination of the debris, and further ensuring the surface quality of the rectangular plastic pipe; thereby utilizing the self-scraping polymer splash-proof machine The structure is that the blocking plate 19 and the blocking plate 20 are fitted with the surface of the rectangular plastic pipe to form a fence on both sides of the rectangular plastic pipe to be cut, and the debris generated during the cutting process will be intercepted by the blocking plate 19 and the blocking plate 20, and the blocking plate 19 and the blocking plate 20 have sufficient thickness to prevent the debris from splashing to the part of the rectangular plastic pipe other than the cutting position, thereby ensuring the surface quality of the rectangular plastic pipe and avoiding the situation where the surface of the rectangular plastic pipe is scratched due to sharp edges or particles contained in the debris; and when the rectangular plastic pipe is cut into two pieces, the two pieces of rectangular plastic pipe can be kept away from each other under the clamping action of the two clamping blocks 10, and when the rectangular plastic pipe is cut into two pieces, the two pieces of rectangular plastic pipe can be clamped by the two clamping blocks 10. When the pipe moves, its surface will scrape against the edges of the blocking plate 20 and the blocking plate 19, so that the debris attached to the cutting position is scraped off and falls into the collection box 6, so as to remove the debris remaining near the cutting position of the rectangular plastic pipe, further ensuring the surface quality of the rectangular plastic pipe; and, by driving the scraper 2 34 and the scraper 1 25 to move respectively, so that the two scrape against the surfaces of the blocking plate 19 and the blocking plate 20, the self-cleaning of the debris remaining on the surface of the blocking plate 19 and the blocking plate 20 is achieved, and the situation that the debris falls on the surface of the rectangular plastic pipe again during subsequent use is avoided, and the repeated contamination of the debris is avoided, and the surface quality of the rectangular plastic pipe is further ensured. ;
