Description

Technical Field

[0001] This invention relates to the field of belt processing equipment technology, specifically to a device for cutting and recycling scrap plastic belts. Background Technology

[0002] Currently in the plastic belt industry, the waste materials cut off are either piled up on-site or coiled into rolls. While this method of using waste material rolls can reduce the space occupied by the waste material, it requires operators to pull the waste material onto the rolls at the beginning and monitor it for a period of time. The main drawback is that this method can collect very little waste material, causing operators to frequently empty the rolls, increasing their workload, and leading to a decrease in equipment uptime. A solution is needed to address the above-mentioned technical problems.

[0003] As shown in the patent document with publication number CN111055311A, this device can be linked with the whole machine for control, and there is no need to stop the machine when processing waste materials; it saves manpower and reduces the workload of operators. There is no need for a dedicated operator to keep an eye on the equipment to process waste materials for a long time. Only periodic inspections are required. If the storage container is large enough, the replacement cycle of the container will be very long, which greatly reduces the frequency of operation; it also reduces operational risks and improves the safety factor of the equipment.

[0004] However, when the above-mentioned cutting and recycling device is in use, the cutting blade has difficulty completely cutting the plastic belt scrap due to its large width, making it inconvenient to carry out subsequent shredding operations and affecting the recycling efficiency of the plastic belt scrap. At the same time, when shredding the plastic belt scrap, the lack of a fixed structure for positioning it makes the plastic belt scrap prone to displacement, affecting the shredding efficiency. Summary of the Invention

[0005] The technical problem solved by this solution is:

[0006] (1) How to solve the problem that the cutting blade cannot completely cut the plastic belt scrap due to its large width, which affects the recycling efficiency of the plastic belt scrap;

[0007] (2) How to solve the problem that the plastic belt scrap is prone to displacement due to the lack of a fixed structure to position the plastic belt scrap, which affects the shredding efficiency.

[0008] The objective of this invention can be achieved through the following technical solution: a plastic belt scrap cutting and recycling device, comprising a housing and an installation plate fixed inside therein, a cutting mechanism for cutting plastic belt scrap is provided on one side of the installation plate, a discharge mechanism for controlling the discharge of plastic belt scrap is provided below the cutting mechanism, and a horizontally arranged cylinder is fixedly installed on the side of the housing, the extended end of the cylinder movably penetrating the housing.

[0009] The cutting mechanism includes a first push plate fixedly connected to the extended end of the cylinder, a first cutting blade arranged horizontally fixedly mounted on the first push plate, a pusher frame fixedly connected to the first push plate below the first cutting blade, a first push wheel rotatably mounted on the pusher frame, and a slitting unit for cutting plastic belt scraps is provided below the first push plate.

[0010] A further technical improvement of the present invention is that: a strip-shaped hole corresponding to the position of the first cutting blade is provided on the side of the mounting plate, a rotating hole is provided on the mounting plate below the strip-shaped hole, a flip plate is rotatably provided on the inner wall of the rotating hole, an electric heating plate is fixedly installed at one end of the flip plate, a heat-conducting strip is fixedly installed on the electric heating plate, and the position of the heat-conducting strip corresponds to the position of the strip-shaped hole.

[0011] A further technical improvement of the present invention is that: a positioning block for preventing excessive rotation of the flipping plate is fixedly installed on the inner wall of the rotating hole; several cutting grooves are opened on the side of the bottom of the rotating hole near the cutting unit; by controlling the extension end of the cylinder to extend from the initial length to the maximum length, during this process, the plastic belt scrap is cut by the first cutting blade in conjunction with the strip hole; at the same time, the electric heating plate is turned on, and the first push wheel provides thrust to the flipping plate, so that the heat-conducting strip on the electric heating plate extends into the strip hole, and in conjunction with the first cutting blade, heats and melts the uncut plastic belt scrap, which facilitates the complete cutting of the plastic belt scrap and avoids the situation where the plastic belt scrap is not completely cut due to its large width, which facilitates subsequent shredding operations and ensures the recycling efficiency of the plastic belt scrap.

[0012] A further technical improvement of the present invention is that: the slitting unit includes a slitting seat fixedly connected to the mounting plate, the top of the slitting seat is provided with a sliding groove, the side wall of the sliding groove near the mounting plate is provided with a cutting groove for receiving the excess plastic belt material, a moving block is slidably arranged in the sliding groove, and a plurality of second cutting blades are arranged horizontally at equal intervals on the moving block, the positions of the plurality of second cutting blades correspond to the positions of the plurality of slitting grooves.

[0013] A further technical improvement of the present invention is that: a push rod is also horizontally fixedly installed on the movable block, one end of the push rod movably passes through the cutting seat and is fixedly connected to a lever, a rotating frame is rotatably arranged on the inner wall of the outer shell above the push rod, the bottom end of the rotating frame is movably connected to the lever, a counterweight is fixedly installed on the top end of the rotating frame, and the top of the rotating frame is rotatably connected to the first push wheel, a connecting plate is fixedly arranged on the inner wall of the outer shell on one side of the push rod, and the connecting plate is elastically connected to the push rod by a tension spring.

[0014] A further technical improvement of the present invention is that: the discharge mechanism includes a flipping frame rotatably disposed at the bottom of the cutting seat, a blocking strip is fixedly installed at one end of the flipping frame, the position of the blocking strip corresponds to the position of the cutting groove, two guide frames are fixedly disposed on the inner wall of the outer shell, and a moving rod is movably inserted on the two guide frames, the moving rod is arranged horizontally, and a second push wheel is rotatably disposed at one end of the moving rod, the second push wheel being rotatably connected to the flipping frame.

[0015] A further technical improvement of the present invention is as follows: a first baffle is fixedly installed in the middle of the moving rod, and a second baffle is fixedly installed at the end of the moving rod away from the second push wheel. A second push plate is provided between the first baffle and the second baffle, and the top end of the second push plate is fixedly connected to the extended end of the cylinder. After the plastic belt residue is completely cut off, it will fall into the cutting groove. As the extended end of the cylinder extends from its initial length to its maximum length, the second push plate pushes the first baffle, causing the second push wheel to provide thrust and support to the tilting frame, extending the blocking strip into the cutting groove to support the plastic belt residue and prevent it from falling. Then, the extended end of the cylinder is controlled to return to its initial length. At this time, the second push plate and the second baffle... There is still a certain distance between them. By retracting the extended end of the cylinder to its shortest length, the first push wheel pushes the rotating frame, which, together with the push rod, drives several second cutting blades to move towards the plastic belt scrap, performing a shredding operation. When all the second cutting blades have entered the corresponding cutting grooves, the second push plate provides a pushing force to the second baffle, causing the second push wheel and the blocking strip to reset, thus causing the shredded plastic belt scrap to fall down. When the several second cutting blades are shredding the plastic belt scrap, the blocking strip provides support, and at the same time, the several second cutting blades, together with the cutting grooves, limit the movement of the plastic belt scrap, thus preventing the plastic belt scrap from easily shifting during the shredding process and ensuring the efficiency of shredding.

[0016] A further technical improvement of the present invention is that: two symmetrically arranged guide plates are fixedly installed on the top of the outer shell, and two transmission rollers for conveying excess plastic belt material are rotatably arranged on the inner wall of the outer shell below the two guide plates.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] In use, this invention controls the extension end of the cylinder to extend from its initial length to its maximum length. During this process, the first cutting blade, in conjunction with the strip-shaped hole, cuts the excess plastic belt material. Simultaneously, the electric heating plate is activated, and the first push wheel provides thrust to the tilting plate, causing the heat-conducting strip on the electric heating plate to extend into the strip-shaped hole. This, in conjunction with the first cutting blade, heats and melts any uncut excess plastic belt material, facilitating complete cutting of the excess plastic belt material. This avoids situations where the excess plastic belt material, due to its large width, cannot be completely cut, thus facilitating subsequent shredding operations and ensuring efficient recycling of the excess plastic belt material.

[0019] In use, the extended end of the control cylinder is reset to its initial length. At this time, there is still a certain distance between the second push plate and the second baffle. By retracting the extended end of the cylinder to its shortest length, the first push wheel pushes the rotating frame, which, together with the push rod, drives several second cutting blades to move toward the plastic belt scrap, performing a shredding operation. When all the second cutting blades have entered the corresponding cutting grooves, the second push plate provides a pushing force to the second baffle, causing the second push wheel and the blocking strip to reset, thereby causing the shredded plastic belt scrap to fall down. When the several second cutting blades shred the plastic belt scrap, the blocking strip provides support, and the several second cutting blades, together with the cutting grooves, limit its movement, thus preventing the plastic belt scrap from easily shifting during the shredding process and ensuring the efficiency of shredding.

[0029] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-7 As shown, a plastic belt scrap cutting and recycling device includes a housing 8 and a mounting plate 7 fixed inside it. A cutting mechanism 1 for cutting plastic belt scrap is provided on one side of the mounting plate 7. A discharge mechanism 4 for controlling the discharge of plastic belt scrap is provided below the cutting mechanism 1. A horizontally arranged cylinder 2 is fixedly installed on the side of the housing 8. The extended end of the cylinder 2 moves through the housing 8.

[0031] Please see Figures 2-4 As shown, the cutting mechanism 1 includes a first push plate 102 fixedly connected to the extended end of the cylinder 2. A first cutting blade 101 arranged horizontally is fixedly installed on the first push plate 102. A pusher frame 103 is fixedly connected to the first push plate 102 below the first cutting blade 101. A first push wheel is rotatably arranged on the pusher frame 103. A slitting unit 104 for cutting plastic belt scraps is arranged below the first push plate 102.

[0032] Please see Figures 2-4 As shown, the mounting plate 7 has a strip hole 105 on its side corresponding to the position of the first cutting blade 101. A rotating hole 109 is provided on the mounting plate 7 below the strip hole 105. A flip plate 107 is rotatably mounted on the inner wall of the rotating hole 109. An electric heating plate 110 is fixedly mounted on one end of the flip plate 107. A heat-conducting strip is fixedly mounted on the electric heating plate 110. The position of the heat-conducting strip corresponds to the position of the strip hole 105.

[0033] Please see Figure 2 and Figure 4 As shown, a positioning block 106 is fixedly installed on the inner wall of the aforementioned rotating hole 109 to prevent the flipping plate 107 from rotating excessively. Several cutting grooves 108 are provided on the bottom side of the rotating hole 109 near the cutting unit 104. By controlling the extension end of the cylinder 2 to extend from its initial length to its maximum length, during this process, the first cutting blade 101, in conjunction with the strip-shaped hole 105, cuts off the remaining plastic belt material. Simultaneously, the electric heating plate 110 is activated, and the first push wheel provides thrust to the flipping plate 107, causing the heat-conducting strip on the electric heating plate 110 to extend into the strip-shaped hole 105, working with the first cutting blade 101 to cut off any uncut material. The plastic belt scrap is heated and melted to ensure complete cutting, preventing incomplete cutting due to its width. This facilitates subsequent shredding and ensures efficient recycling. The heat-conducting strip, in conjunction with the first cutting blade 101, completely cuts the scrap, allowing it to fall off and enabling subsequent shredding. Because the cut scrap is relatively narrow, it is easily severed; any incomplete cutting does not affect collection.

[0034] Please see Figure 2 , Figure 5 and Figure 6 As shown, the above-mentioned slitting unit 104 includes a slitting seat 1046 fixedly connected to the mounting plate 7. A sliding groove 1047 is provided on the top of the slitting seat 1046. A cutting groove 1048 for receiving plastic belt scrap is provided on the side wall of the sliding groove 1047 near the mounting plate 7. A moving block 1042 is slidably arranged in the sliding groove 1047. A plurality of second cutting blades 1049 are arranged horizontally at equal intervals on the moving block 1042. The positions of the plurality of second cutting blades 1049 correspond to the positions of the plurality of slitting grooves 108.

[0035] Please see Figure 5 and Figure 6 As shown, a push rod 1045 is also horizontally fixedly installed on the aforementioned movable block 1042. One end of the push rod 1045 movably passes through the cutting seat 1046 and is fixedly connected to a lever 1043. A rotating frame is rotatably installed on the inner wall of the outer shell 8 above the push rod 1045. The bottom end of the rotating frame is movably connected to the lever 1043. A counterweight block 1041 is fixedly installed on the top end of the rotating frame, and the top of the rotating frame is tumblingly connected to the first push wheel. A connecting plate 1044 is fixedly installed on the inner wall of the outer shell 8 on one side of the push rod 1045. The connecting plate 1044 and the push rod 1045 are elastically connected by a tension spring.

[0036] Please see Figure 7As shown, the above-mentioned discharge mechanism 4 includes a flipping frame 407 rotatably disposed at the bottom of the cutting seat 1046. A blocking strip 408 is fixedly installed at one end of the flipping frame 407. The position of the blocking strip 408 corresponds to the position of the cutting groove 1048. Two guide frames 401 are fixedly disposed on the inner wall of the outer shell 8. A moving rod 405 is movably inserted on the two guide frames 401. The moving rod 405 is arranged horizontally, and a second push wheel 406 is rotatably disposed at one end of the moving rod 405. The second push wheel 406 is rolledly connected to the flipping frame 407.

[0037] Please see Figure 1 and Figure 7 As shown, a first baffle 404 is fixedly installed in the middle of the aforementioned moving rod 405, and a second baffle 403 is fixedly installed at the end of the moving rod 405 away from the second push wheel 406. A second push plate 402 is provided between the first baffle 404 and the second baffle 403, and the top end of the second push plate 402 is fixedly connected to the extended end of the cylinder 2. When the extended end of the cylinder 2 is controlled to return to its initial length, there is still a certain distance between the second push plate 402 and the second baffle 403. By retracting the extended end of the cylinder 2 to its shortest length, the first push wheel pushes the rotating frame, which, together with the push rod 1045, drives several second cutting blades 1049 toward the plastic belt. The remaining material moves and is shredded. When several second cutting blades 1049 enter the corresponding slitting grooves 108, the second push plate 402 provides a pushing force to the second baffle 403, causing the second push wheel 406 and the blocking strip 408 to reset, thereby causing the shredded plastic belt material to fall down. When several second cutting blades 1049 shred the plastic belt material, the blocking strip 408 provides support for it. At the same time, several second cutting blades 1049 cooperate with the cutting grooves 1048 to limit it, thereby preventing the plastic belt material from easily shifting during the shredding process and ensuring the efficiency of shredding.

[0038] Please see Figure 1 As shown, a mounting base 3 for supporting the cylinder 2 is fixedly connected to the side of the outer casing 8.

[0039] Please see Figure 1 As shown, a discharge port 6 is provided at the bottom of the outer shell 8 on one side of the mounting plate 7. A discharge trough 5 for guiding the excess material of the plastic belt is fixedly installed at the bottom of the outer shell 8 through a connecting bracket. The discharge trough 5 is located below the discharge port 6.

[0040] Please see Figure 1 As shown, two symmetrically arranged guide plates 10 are fixedly installed on the top of the outer shell 8, and two drive rollers 9 for conveying excess plastic belt material are rotatably arranged on the inner wall of the outer shell 8 below the two guide plates 10.

[0041] Working Principle: In use, the excess plastic belt material is first extended into the housing 8 through two guide plates 10, and then moved to the cutting station by two drive rollers 9. At this time, the bottom of the excess plastic belt material is located between the strip hole 105 and the first cutting blade 101. By controlling the extension end of the cylinder 2 to extend from its initial length to its maximum length, the excess plastic belt material is cut by the first cutting blade 101 in conjunction with the strip hole 105. Simultaneously, the electric heating plate 110 is turned on, and the first push wheel provides thrust to the flipping plate 107, causing the electric heating plate 110 to... The heat-conducting strip on the cylinder 2 extends into the strip-shaped hole 105, working with the first cutting blade 101 to heat and melt the uncut plastic belt scrap, facilitating complete cutting of the scrap and preventing incomplete cutting due to its width. This facilitates subsequent shredding operations and ensures efficient recycling of the plastic belt scrap. After complete cutting, the scrap falls into the cutting groove 1048. As the cylinder 2 extends from its initial length to its maximum length, the second push plate 402 pushes the first baffle 404, causing... The second push wheel 406 provides thrust and support to the tilting frame 407, extending the blocking strip 408 into the cutting groove 1048 to support the plastic belt residue and prevent it from falling. Then, the extended end of the cylinder 2 is controlled to return to its initial length. At this point, there is still a certain distance between the second push plate 402 and the second baffle 403. The cylinder 2's extended end retracts to its shortest length, causing the first push wheel to push the rotating frame. This, in conjunction with the push rod 1045, drives several second cutting blades 1049 towards the plastic belt residue, performing a shredding operation. When several second cutting blades 1049... When all 49 blades enter the corresponding cutting groove 108, the second push plate 402 provides a pushing force to the second baffle 403, causing the second push wheel 406 and the blocking strip 408 to reset, thereby causing the shredded plastic belt residue to fall down. When the several second cutting blades 1049 shred the plastic belt residue, the blocking strip 408 provides support for it. At the same time, the several second cutting blades 1049 cooperate with the cutting groove 1048 to limit it, thereby preventing the plastic belt residue from easily shifting during the shredding process and ensuring the efficiency of shredding.
