[0003] A patent application with publication number CN215094953U discloses a PVC film calender edge material crushing and recovery device, including a device main body, a vibration plate is arranged at the lower end of the inner cavity of the device main body, both sides of the vibration plate are fixedly connected with limiting slide blocks, both sides of the lower end of the inner cavity of the device main body are provided with limiting slide grooves, the limiting slide blocks are located inside the limiting slide grooves, and a material drop groove is opened in the middle of the vibration plate. By arranging a vibration plate at the lower end of the inner cavity of the device main body, setting a filter plate on the vibration plate, and then arranging vibration motors at both ends of the bottom of the device main body, the vibration motor drives the vibration plate to vibrate, which can avoid clogging of the filter plate and improve the working efficiency of the device.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] like Figure 1-6As shown, a PVC film calender edge material crushing and recycling device described in an embodiment of the present invention includes a crushing box 1, a feed port 12 is fixedly installed on the top of the crushing box 1, a support leg 11 is fixedly installed on the bottom of the crushing box 1, a filter plate 13 is fixedly installed on the lower end of the inner part of the crushing box 1, an isolation plate 15 is fixedly installed on the inner wall of the crushing box 1 above the filter plate 13, a plurality of crushing motors 41 are fixedly installed inside the isolation plate 15, a crushing roller 42 is fixedly installed on the bottom end of the crushing motor 41, a plurality of crushing rods 43 are fixedly installed on the outer wall of the crushing roller 42, a feed separation device 2 for feeding is provided on the inner wall of the upper end of the crushing box 1, and the feed separation device 2 includes: a plurality of first annular fixed plates 26 fixedly installed on the inner wall of the crushing box 1, a first telescopic rod 25 is fixedly installed on the side wall of the first annular fixed plate 26, and the A trigger plate 251 is fixedly installed on the side wall of the first telescopic rod 25, and a first spring 252 is fixedly installed on the end of the trigger plate 251; a first slide column 24 is slidably installed on the outer wall of the first telescopic rod 25; a first motor 23 is slidably installed inside the first annular fixed plate 26; the first slide column 24 is fixedly connected to the first motor 23; a feeding roller 21 is fixedly installed on the output shaft of the first motor 23; the feeding roller 21 is coaxial with the first slide column 24; a plurality of feeding pull rods 211 are fixedly installed on the outer wall of the feeding roller 21; a second annular fixed plate 27 is fixedly installed on the inner wall of the crushing box 1 and is located below the first annular fixed plate 26; a limiting slide groove 274 is fixedly installed on the inner wall of the second annular fixed plate 27; a moving block 294 is slidably installed on the inner wall of the limiting slide groove 274; a cutting knife 28 is fixedly installed on the side wall of the moving block 294.

[0036] Specifically, after the calender calenders the PVC film, irregular strips of waste will be generated. These wastes are processed and crushed into granules, which can be used again. In order to process them into granules of appropriate size, the granular materials are easily melted by heat and filtered through a filter to screen out particles of appropriate size. When the waste is crushed, it is affected by the irregular shape of the waste. Therefore, in the process of crushing the waste, it is necessary to control the feeding speed to prevent the problem that the oversized waste is unevenly crushed and cannot pass through the filter. In order to solve this problem, the following improvements have been made:

[0037] Before the waste is crushed, the first motor 23 and the crushing motor 41 are turned on, and then the waste is fed in from the position of the feed port 12. The rotation of the first motor 23 drives the feeding roller 21 to rotate, and the rotation of the feeding roller 21 drives the feeding rod 211 on the outer wall to rotate. The rotating feeding rod 211 can pull the waste into the inside of the crushing box 1, and the waste continues to fall into the inside of the crushing box 1 through the pulling of the feeding roller 21. Due to the uneven size of the waste, the waste at the rear end is pulled onto the feeding roller 21 during the feeding and pulling process. At this time, the waste will squeeze the feeding rollers 21 at both ends to move toward the length edge of the crushing box 1, and one side of the feeding roller 21 The first motor 23 is fixedly installed, and the first slide column 24 is fixedly installed at one end of the output shaft of the first motor 23, thereby driving the first slide column 24 to move horizontally along the width direction of the crushing box 1. When the first slide column 24 touches the trigger plate 251, the trigger plate 251 is a trigger switch that can cut off and merge the power supply. Therefore, the first motor 23 is powered off, and the side wall of the second annular fixed plate 27 is fixedly installed with a cylinder 271, and the end of the cylinder 271 is fixedly installed on the outer wall of the moving block 294. When the first motor 23 is powered off, the cylinder 271 is started, and the output end of the cylinder 271 drives the side wall of the moving block 294 to be fixedly installed. The cutting knives 28 are extended, and the sides of the two cutting knives 28 that are close to each other are both sharpened. When the cutting knives 28 are extended, the cutting edges of the two cutting knives 28 are close to each other until the two cutting knives 28 contact each other. The cylinder 271 is extended to the maximum state, and the waste can be cut. The cut waste will fall downward, pass through the isolation plate 15, and contact with multiple crushing rollers 42. The crushing rollers 42 are fast-rotating crushing knives, which crush the waste into particles through high-speed rotation. The granular waste can be reused after being filtered by the filter plate 13. After the cut waste is crushed, the cylinder 271 retracts, thereby driving the cutting When the cutting knife 28 is retracted, the trigger plate 251 will energize the first motor 23 again, so that the feeding roller 21 will start to run again until it touches the trigger plate 251 again, and then the first motor 23 will be turned off. After the cutting knife 28 of this device cuts the waste, the strips and blocks of waste are crushed by the crushing rod 43, which reduces the problem of insufficient crushing of the waste due to the pulling of the strips of waste by the crushing rod 43, resulting in clogging of the filter plate 13. The trigger plate 251 is triggered by the squeezing of the feeding roller 21 by the waste to cut off the power of the first motor 23 and stop feeding, thereby reducing the problem of excessive pulling of the waste when feeding and insufficient crushing.

[0038] like Figure 3-5As shown, the feed separation device 2 also includes: a cutting saw blade 29 slidably mounted on the inner wall of the cutting knife 28, and the cutting saw blade 29 is serrated; a saw blade protrusion 291 fixedly mounted at the end of the cutting saw blade 29; a second threaded rod 292 threadedly connected to the inner wall of the saw blade protrusion 291, and a threaded support slide rod 293 is fixedly mounted at the end of the second threaded rod 292, and the end of the threaded support slide rod 293 is rollingly mounted on the inner wall of the moving block 294.

[0039] Specifically, when the cylinder 271 drives the cutting blade 28 to cut the strip-shaped and block-shaped waste, the waste may still be incompletely cut, resulting in the problem that the crushed waste is involved with the waste cut at the upper end. Therefore, after the cutting blade 28 cuts, the motor can be used to drive the threaded support slide bar 293 inside the moving block 294 to rotate, and the rotation of the threaded support slide bar 293 drives the second threaded rod 292 of the side wall to rotate. The rotation of the second threaded rod 292 causes the saw blade protrusion 291 to move inside the cutting blade 28. The second threaded rod 292 is connected to the cutting saw blade 29, thereby driving the cutting saw blade 29 to slide inside the cutting knife 28, and the outer wall of the second threaded rod 292 is a reciprocating thread. When the second threaded rod 292 rotates, it can drive the saw blade protrusion 291 to reciprocate. When the cutting knife 28 cuts, the cutting saw blade 29 slides on the inner wall of the cutting knife 28. The cutting saw blade 29 can separate the waste that is not completely cut by the cutting knife 28, thereby improving the cutting ability of the cutting knife 28 and making the waste cut completely.

[0040] like Figure 4-5 As shown, the feed separation device 2 also includes: a long tooth 272 fixedly mounted on the inner wall of the bottom end of the cylinder 271; a driven gear 273 fixedly mounted on the end of the threaded support slide rod 293, and the outer wall of the driven gear 273 is meshed with the long tooth 272.

[0041] Specifically, considering that when the cutting knife 28 is cutting, the cutting state of the cutting saw blade 29 can be cut synchronously according to the movement of the cutting knife 28, a long tooth 272 is provided on the inner wall of the bottom end of the second annular fixed plate 27. When the cylinder 271 extends to drive the moving block 294 to slide, the moving block 294 drives the cutting knife 28 to move, thereby driving the driven gear 273 to rotate, and the rotating driven gear 273 drives the threaded support slide rod 293 fixedly installed on the side wall to rotate, thereby driving the cutting saw blade 29 to reciprocate when the cutting knife 28 is cutting, thereby realizing the function of synchronous cutting.

[0042] like Figure 4-5 As shown, a feeding shell 22 is rollingly mounted on the outer wall of the end of the feeding roller 21 and the outer wall of the output shaft of the first motor 23. The feeding shell 22 is in the shape of a hollow semi-cylindrical shape, and the inner diameter of the feeding shell 22 is larger than the protruding length of the feeding rod 211 on the outer wall of the feeding roller 21.

[0043] Specifically, considering that the loading roller 21 may cause the waste to be scattered inside the crushing box 1 due to the entanglement of the waste when transporting the waste, a loading shell 22 is arranged inside the crushing box 1 to prevent the waste from being scattered when entering, and the inner diameter of the loading shell 22 is larger than the extended length of the loading rod 211 on the outer wall of the loading roller 21, so that the loading roller 21 and the loading rod 211 can operate normally, and the shape of the loading shell 22 can be adapted to the outer shape of the loading roller 21.

[0044] like Figure 2-3 and Figure 7-8 As shown, the outer wall of the lower end of the feeding shell 22 is provided with a cleaning device 3 for cleaning the outer wall of the feeding roller 21, and the cleaning device 3 includes: two first threaded rods 34 and a limiting slide 35 fixedly installed on the outer wall of the feeding shell 22; a second fixed block 31 threadedly connected to the outer wall of the first threaded rod 34, and the limiting slide 35 slides on the inner wall of the second fixed block 31; a scraping rod 32 fixedly installed on the side wall of the second fixed block 31, and the outer wall of the feeding shell 22 is provided with a hole adapted to the sliding of the scraping rod 32; and a second motor 33 fixedly installed at the end of the first threaded rod 34.

[0045] Specifically, considering that the waste may be entangled on the outer wall of the loading roller 21 when the loading rod 211 on the outer wall of the loading roller 21 pulls the waste, reducing the ability of the loading roller 21 to pull the waste and increasing the burden of the first motor 23 during operation, a cleaning device 3 is provided on the outer wall of the loading shell 22. When waste is entangled on the outer wall of the loading roller 21, the second motor 33 is started, and the second motor 33 rotates to drive the first threaded rod 34 to rotate, and the rotation of the first threaded rod 34 drives the second fixed block 31 to move toward the center of the loading shell 22, and the side wall of the second fixed block 31 is provided with a scraping rod 32, which can drive the scraping rod 32 to be inserted into the outer wall of the loading roller 21 for scraping, thereby cleaning the strip waste entangled on the outer wall of the loading roller 21 and reducing the problem of waste entanglement on the outer wall of the loading roller 21.

[0046] like Figure 3 and Figure 7-8 As shown, the scraping rod 32 is installed in a cross-staggered manner with the feeding pull rod 211 on the outer wall of the feeding roller 21.

[0047] Specifically, the scraper rod 32 is installed crosswise and staggered with the loading rod 211 on the outer wall of the loading roller 21 to prevent the loading rod 211 from colliding with the scraper rod 32 when the scraper rod 32 extends to the inner wall of the loading shell 22, causing the loading roller 21 to be unable to rotate.

[0048] like Figure 4-5As shown, the length of the cutting saw blade 29 is smaller than the length of the cutting knife 28 , and the protruding length of the cutting saw blade 29 does not exceed the edge of the cutting knife 28 .

[0049] Specifically, the length of the cutting saw blade 29 is smaller than the length of the cutting knife 28, so that the cutting saw blade 29 will not fall off when it reciprocates inside the cutting knife 28, and the extended length of the cutting saw blade 29 does not exceed the edge of the cutting knife 28 to prevent the cutting saw blades 29 from colliding after the two cutting knives 28 are merged.

[0050] like Figure 6 As shown, a landslide funnel 14 is fixedly installed at the bottom end of the crushing box 1, and a discharge port 141 is arranged at the bottom end of the landslide funnel 14, and the landslide funnel 14 is funnel-shaped.

[0051] Specifically, the landslide funnel 14 is in the shape of a funnel. When the granular waste material falls into the landslide funnel 14 , the waste material can leak out from the discharge port 141 .

[0052] like Figure 1 As shown, the bottom inlet of the feed port 12 is smaller than the length of the loading shell 22 .

[0053] Specifically, the bottom inlet of the feed port 12 is smaller than the length of the feed shell 22 , so that when the waste enters the inside of the crushing box 1 , it will not leak out from the edge of the feed shell 22 .

[0054] like Figure 2-3 As shown, the maximum running extent of the first threaded rod 34 is smaller than the distance between the feeding roller 21 and the feeding housing 22 .

[0055] Specifically, the maximum running range of the first threaded rod 34 is smaller than the distance between the loading roller 21 and the loading shell 22, so as to prevent the scraping rod 32 from extending too long when extending into the loading shell 22 and squeezing the loading roller 21.

[0056] Working principle: before the waste is crushed, the first motor 23 and the crushing motor 41 are turned on, and then the waste is fed in from the position of the feed port 12. The rotation of the first motor 23 drives the feeding roller 21 to rotate, and the rotation of the feeding roller 21 drives the feeding rod 211 on the outer wall to rotate. The rotating feeding rod 211 can pull the waste into the crushing box 1, and the waste continues to fall into the crushing box 1 through the pulling of the feeding roller 21. Due to the uneven size of the waste, there will be a problem of too much waste when it is added to the crushing box 1. At this time, the waste will squeeze the feeding rollers 21 at both ends to move outward, thereby driving the first sliding column 24 to move toward the inner wall of the crushing box 1. When the first slide column 24 touches the trigger plate 251, the trigger plate 251 is a trigger switch that can cut off and merge the power supply, so the first motor 23 is disconnected, and the side wall of the second annular fixed plate 27 is fixedly installed with a cylinder 271, and the end of the cylinder 271 is fixedly installed on the outer wall of the moving block 294. After the first motor 23 is disconnected, the cylinder 271 is opened, and the cylinder 271 extends to drive the cutting knife 28 fixedly installed on the side wall of the moving block 294 to extend, so that the waste can be cut. When the cylinder 271 extends to drive the moving block 294 to slide, the moving block 294 drives the cutting knife 28 to move, thereby driving the driven gear 273 to rotate, and the rotating driven gear The wheel 273 drives the threaded support slide bar 293 fixedly installed on the side wall to rotate, and the rotation of the threaded support slide bar 293 drives the second threaded rod 292 of the side wall to rotate. The rotation of the second threaded rod 292 causes the saw blade protrusion 291 to slide inside the cutting knife 28, and the saw blade protrusion 291 is connected to the cutting saw blade 29, thereby driving the cutting saw blade 29 to slide inside the cutting knife 28, and the outer wall of the second threaded rod 292 is a reciprocating thread. When the second threaded rod 292 rotates, it can drive the saw blade protrusion 291 to reciprocate. When the cutting knife 28 cuts, the cutting saw blade 29 slides on the inner wall of the cutting knife 28, and the cutting saw blade 29 can cut the cutting knife 28 Incomplete waste is separated. When the cut waste is crushed, the cylinder 271 retracts, thereby driving the cutting knife 28 to retract, and the trigger plate 251 will turn on the first motor 23 again, so that the feeding roller 21 runs again, until it touches the trigger plate 251 again, and then the first motor 23 will be turned off. After the cutting knife 28 of this device cuts the waste, the strips and blocks of waste are crushed by the crushing rod 43, which reduces the problem of the crushing rod 43 being pulled by the strips of waste when crushing. The trigger plate 251 is triggered by the squeezing of the waste on the feeding roller 21 to pause the first motor 23 and stop feeding, thereby reducing the problem of insufficient crushing caused by the feeding of a large amount of waste.

[0057] When cleaning the outer wall of the loading roller 21, start the second motor 33, and the rotation of the second motor 33 drives the first threaded rod 34 to rotate, and the rotation of the first threaded rod 34 drives the second fixed block 31 to move toward the center of the upper material shell 22, and the side wall of the second fixed block 31 is provided with a scraping rod 32, which can drive the scraping rod 32 to be inserted into the outer wall of the loading roller 21 for scraping, thereby cleaning the strip waste wrapped around the outer wall of the loading roller 21 and reducing the problem of waste wrapped around the outer wall of the loading roller 21.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
