Description

Technical Field

[0001] This invention belongs to the technical field of film recycling equipment, specifically a plastic film recycling and crushing device. Background Technology

[0002] Plastic film is widely used in industries such as industry, agriculture, logistics and warehousing, and daily necessities. As the consumption of film products continues to increase, the amount of waste film is also increasing. If the application and post-processing of waste film are not handled properly, it will inevitably damage the environment and endanger people's health. Therefore, it is necessary to recycle and reuse waste film to turn waste into treasure.

[0003] A patent application with publication number CN119141733B discloses a plastic film recycling and crushing device. By adding a guiding mechanism to one side of the crusher, the guiding mechanism pulls the plastic film forward via push hooks on a conveyor belt. A downward-pressing cylinder controls the lowering of the pressure table, causing the plastic film to adhere to the guiding table so that the push hooks can catch it. Drive rollers are also provided on both sides of the guiding table, cooperating with the first and second pressure rollers respectively to increase the conveying force on the plastic film, allowing it to be guided into the crusher through the guide box, thus achieving orderly feeding of the plastic film into the crusher.

[0004] In the aforementioned prior art, crushing rollers are generally used to crush plastic films. Since plastic films are relatively thin and light, waste plastic films are usually collected in clumps. When clumps of plastic films enter the crushing rollers for crushing, the clumps can easily lead to uneven feeding, fluctuations in equipment load, and even blockages or jams, increasing the risk of machine motor overload.

[0005] Therefore, the present invention provides a plastic film recycling and crushing device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

The separation component includes a first cylindrical rod slidably arranged on the upper end of the workbench, two sets of pointed rods are rotatably arranged on the upper end of the outer side of the first cylindrical rod, the two sets of several pointed rods are inclined to both sides respectively, and several pointed rods are rotatably arranged on the outer side of the first cylindrical rod, with adjacent two pointed rods placed crosswise.

[0008] Preferably, arc-shaped blocks are fixed to both sides of the first cylindrical rod by brackets, and the lower end of the arc-shaped blocks is fixed to the upper end of the worktable by a first telescopic rod.

[0009] Preferably, a first rectangular strip is fixed to the upper end of several of the pointed rods in the same group, and a circular slider is fixed to each end of the first rectangular strip. An arc groove is opened on the opposite side of each arc block, and the circular slider is slidably disposed in the arc groove.

[0010] Preferably, a second rectangular bar is slidably provided on the upper end of the pointed rod. The second rectangular bar is located in the middle of the upper ends of the two sets of pointed rods. A first cylindrical bar is fixedly connected to the upper end of the second rectangular bar. A third rectangular bar is fixedly connected to the upper end of the first cylindrical bar. The lower end of the third rectangular bar is fixedly connected to the upper end of the worktable through a second telescopic rod.

[0011] Preferably, side plates are installed on both sides of the conveyor belt, L-shaped rods are fixed to both sides of the arc-shaped block, and rectangular blocks are fixed to one side of the conveyor belt at the positions corresponding to the L-shaped rods, with the height of the rectangular blocks being flush with the conveyor belt.

[0012] Preferably, an extrusion plate is slidably disposed on the upper end of the workbench away from the crushing box, and the extrusion plate is located on one side of several pointed rods.

[0013] Preferably, a rectangular plate is fixed to the upper end of the extrusion plate by a second cylindrical strip, and the two sides of the rectangular plate are fixed to the upper end of the worktable by a third telescopic rod.

[0014] Preferably, a cutting blade is provided on each side of the rectangular plate, an L-shaped block is fixedly connected to each side of the rectangular plate, a rectangular tube is fixedly connected to the lower end of the L-shaped block, the cutting blade is slidably disposed inside the rectangular tube, and the cutting blade is fixedly connected to the inside of the rectangular tube by a spring.

[0015] Preferably, the extrusion plate has a feeding port on the side away from the pointed rod, the feeding port is fixed to the upper end of the base plate by a third support rod, and an inclined plate is fixed to the upper end of the worktable near the crushing box, the inclined plate is located on the side of the conveyor belt.

[0016] Preferably, a rectangular box is fixedly connected to the upper end of the base plate, the crushing box is located on one side of the upper end of the rectangular box, and a plurality of second cylindrical rods are rotatably arranged on the upper end of the rectangular box, and a plurality of levers are fixedly connected to the side of the second cylindrical rods.

[0017] The beneficial effects of this invention are as follows: 1. The plastic film recycling and crushing device of the present invention drives the first cylindrical rod to move downward, causing the pointed rod to approach the clump of plastic film, so that the pointed rod inserts into the clump of plastic film. Then, it drives two sets of pointed rods to rotate in opposite directions, thereby causing the clump of plastic film to separate. Before the clump of plastic film enters the crushing box, it separates the clump of plastic film, reducing the phenomenon of clumps of plastic film entanglement. This greatly reduces the risk of uneven feeding caused by clumps of plastic film, which can easily lead to equipment load fluctuations, or even blockage and jamming, and increase the risk of machine motor overload.

[0018] 2. The plastic film recycling and crushing device of the present invention retracts by driving a third telescopic rod. The third telescopic rod drives a pressing plate to move downward through a rectangular plate and a second cylindrical strip, squeezing the clump of plastic film at the upper end of the conveyor belt. This keeps the upper end of the clump of plastic film flat and prevents the clump of plastic film from getting caught on the side of the pointed rod when it slides towards it, thus preventing it from moving completely to the lower end of the pointed rod. When the rectangular plate moves downward, it simultaneously drives an L-shaped block to move downward. The L-shaped block drives a cutting blade downward through a rectangular cylinder. The cutting blades on both sides of the rectangular plate cut the plastic film at the upper end of the conveyor belt. During cutting, the cutting blade slides into the rectangular cylinder and compresses the spring to prevent damage to the lower end of the conveyor belt. This preliminary cutting of the clump of plastic film prevents the plastic film from being too long and getting tangled on the outside of the crushing roller when it enters the crushing box for crushing.

Detailed Implementation

[0021] 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.

[0022] Example 1: As Figure 1 - Figure 6 As shown in the embodiment of the present invention, a plastic film recycling and crushing device includes a workbench 1, a base plate 7 at the lower end of the workbench 1, the workbench 1 being fixed to the upper end of the base plate 7 by a second support rod 71, a crushing box 5 on one side of the workbench 1, the crushing box 5 being fixed to the upper end of the base plate 7 by a first support rod 53, two crushing rollers 51 being rotatably arranged inside the crushing box 5, a conveyor belt 2 being installed on the upper end of the workbench 1, and a separation component being slidably arranged on the upper end of the workbench 1. The separation component includes a first cylindrical rod 12 slidably arranged on the upper end of the workbench 1, two sets of pointed rods 11 being rotatably arranged on the upper end of the outer side of the first cylindrical rod 12, the two sets of several pointed rods 11 being inclined to both sides respectively, and several pointed rods 11 being rotatably arranged on the outer side of the first cylindrical rod 12, with adjacent two pointed rods 11 being placed crosswise.

[0023] Specifically, when crushing plastic film, a crushing roller 51 is generally used. Because plastic film is relatively thin and light, and waste plastic film is usually collected in clumps, these clumps can easily cause uneven feeding when entering the crushing roller 51, leading to fluctuations in equipment load and even blockages or jamming, increasing the risk of motor overload. When using this recycling and crushing device, the conveyor belt 2 is started to transport the clumps of plastic film to the lower end of the pointed rod 11. Then, the first cylindrical rod 12 is driven to slide downwards, causing several pointed rods 11 to slide downwards as well. As the pointed rods 11 move downwards, they insert into the clumps of plastic film at the lower end. The two sets of pointed rods 11 rotate in opposite directions, thereby separating the clumps of plastic film. Then, the pointed rods... 11 moves upward and then continues to drive the conveyor belt 2, moving the separated plastic film closer to the crushing box 5, causing the plastic film to fall into the crushing box 5. Then, the crushing roller 51 is started to rotate, crushing the separated plastic film. By driving the first cylindrical rod 12 downward, the pointed rod 11 moves closer to the clump of plastic film, causing the pointed rod 11 to insert into the clump of plastic film. Then, the two sets of pointed rods 11 are driven to rotate in opposite directions, thereby separating the clump of plastic film. Before the clump of plastic film enters the crushing box 5, the clump of plastic film is separated, reducing the phenomenon of clumps of plastic film entanglement. This greatly reduces the risk of uneven feeding caused by clumps of plastic film, which can easily lead to equipment load fluctuations, or even blockage and jamming, and increase the risk of machine motor overload.

[0024] like Figure 3 As shown, arc-shaped blocks 14 are fixed to both sides of the first cylindrical rod 12 via brackets 13, and the lower end of the arc-shaped blocks 14 is fixed to the upper end of the workbench 1 via the first telescopic rod 142.

[0025] like Figure 3 As shown, a first rectangular bar 111 is fixedly connected to the upper end of several pointed rods 11 in the same group. Circular sliders 112 are fixedly connected to both ends of the first rectangular bar 111. Arc grooves 141 are respectively opened on opposite sides of the arc blocks 14, and the circular sliders 112 are slidably disposed in the arc grooves 141.

[0026] like Figure 3 As shown, a second rectangular bar 15 is slidably disposed on the upper end of the pointed rod 11. The second rectangular bar 15 is located in the middle of the upper end of the two sets of pointed rods 11. A first cylindrical bar 151 is fixedly connected to the upper end of the second rectangular bar 15. A third rectangular bar 152 is fixedly connected to the upper end of the first cylindrical bar 151. The lower end of the third rectangular bar 152 is fixedly connected to the upper end of the workbench 1 through a second telescopic rod 153.

[0027] like Figure 4As shown, side plates 21 are installed on both sides of the conveyor belt 2, and L-shaped rods 143 are fixed to both sides of the arc-shaped block 14. Rectangular blocks 22 are fixed to one side of the conveyor belt 2 at the position corresponding to the L-shaped rods 143. The height of the rectangular blocks 22 is flush with that of the conveyor belt 2.

[0028] Specifically, a clump of plastic film is placed on the upper end of conveyor belt 2 and conveyed to the lower end of the pointed rod 11. Then, the first telescopic rod 142 is driven to retract, causing the arc-shaped block 14 to move downwards. The arc-shaped block 14, through the circular slider 112 and the first rectangular strip 111, drives the pointed rod 11 downwards, allowing the first rectangular strip 111 to insert into the clump of plastic film. Simultaneously, the second telescopic rod 153 is driven to retract synchronously with the first telescopic rod 142. The second telescopic rod 153 drives the third rectangular strip 152 to slide downwards. The third rectangular strip 152, through the first cylindrical strip 151, drives the second rectangular strip 15 downwards, causing the second rectangular strip 15 to slide downwards synchronously with the pointed rod 11. At the same time, the arc-shaped block 14 causes the L-shaped rod 143 to abut against the upper end of the rectangular block 22. The length of the L-shaped rod 143 is longer than the length of the pointed rod 11 to prevent the pointed rod 11 from damaging the conveyor belt 2. When the pointed rod 11 is inserted into the clump of plastic film, the first telescopic rod 142 remains stationary. Then, the second telescopic rod 153 is driven to retract. The third rectangular bar 152 and the first cylindrical bar 151 drive the second rectangular bar 15 to slide downward between the two sets of pointed rods 11, thereby causing the lower ends of the two sets of pointed rods 11 to move to opposite ends, separating the clump of plastic film. Then, the first telescopic rod 142 and the second telescopic rod 153 are driven to extend, causing the pointed rods 11 to move upward. The second telescopic rod 153 drives the second rectangular bar 15 to move to the upper end of the two sets of pointed rods 11. Since the pointed rods 11 are rotated outside the first cylindrical bar 12 by a torsion spring, when the second rectangular bar 15 moves upward, the pointed rods 11 rotate outside the first cylindrical bar 12, which can reduce the included angle between the upper ends of the two sets of pointed rods 11, making it easier to separate the clump of plastic film next time.

[0029] like Figure 5 As shown, an extrusion plate 3 is slidably disposed on the upper end of the workbench 1 away from the crushing box 5, and the extrusion plate 3 is located on one side of several pointed rods 11.

[0030] like Figure 5 As shown, a rectangular plate 32 is fixed to the upper end of the extrusion plate 3 via a second cylindrical strip 31, and the two sides of the rectangular plate 32 are fixed to the upper end of the workbench 1 via a third telescopic rod 33.

[0031] like Figure 5As shown, a cutting blade 34 is provided on both sides of the rectangular plate 32, and an L-shaped block 343 is fixedly connected to both sides of the rectangular plate 32. A rectangular tube 341 is fixedly connected to the lower end of the L-shaped block 343. The cutting blade 34 is slidably disposed inside the rectangular tube 341 and is fixedly connected to the rectangular tube 341 by a spring 342.

[0032] like Figure 2 As shown, the extrusion plate 3 is provided with a feeding port 4 on the side away from the pointed rod 11. The feeding port 4 is fixed to the upper end of the base plate 7 by the third support rod 41. An inclined plate 23 is fixed to the upper end of the workbench 1 near the crushing box 5. The inclined plate 23 is located on the side of the conveyor belt 2.

[0033] Specifically, the clump of plastic film is fed into the feed inlet 4 and then falls onto the upper end of the conveyor belt 2. The conveyor belt 2 is started, moving the clump of plastic film to the lower end of the extrusion plate 3. Then, the third telescopic rod 33 is driven to retract. The third telescopic rod 33, through the rectangular plate 32 and the second cylindrical strip 31, moves the extrusion plate 3 downward, extruding the clump of plastic film on the upper end of the conveyor belt 2. This keeps the upper end of the clump of plastic film flat and prevents the clump of plastic film from getting caught on the pointed rod 11 when it slides towards the pointed rod 11, thus preventing it from moving completely. When the rectangular plate 32 moves downward to the lower end of the pointed rod 11, it simultaneously drives the L-shaped block 343 to move downward. The L-shaped block 343 drives the cutting blade 34 to move downward through the rectangular cylinder 341. The cutting blades 34 on both sides of the rectangular plate 32 cut the plastic film at the upper end of the conveyor belt 2. During the cutting, the cutting blade 34 slides into the rectangular cylinder 341 and squeezes the spring 342 to prevent damage to the lower end of the conveyor belt 2. The clump of plastic film is initially cut to prevent the plastic film from being too long and getting tangled on the outside of the crushing roller 51 when it enters the crushing box 5 for crushing.

[0034] Example 2: Figure 7 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a rectangular box 6 is fixedly connected to the upper end of the base plate 7, the crushing box 5 is located on one side of the upper end of the rectangular box 6, and a plurality of second cylindrical rods 61 are rotatably arranged on the upper end of the rectangular box 6, and a plurality of levers 62 are fixedly connected to the side of the second cylindrical rods 61.

[0035] Specifically, the crushed plastic film forms plastic fragments containing dust and impurities, which need to be cleaned before further processing. After being crushed in the crushing box 5, the plastic film falls into the rectangular box 6, which is filled with clean water. Then, the second cylindrical rod 61 is driven to rotate, which in turn drives several levers 62 to rotate in the water. The levers 62 move the plastic fragments in the water, making full contact between the plastic fragments and the water to clean them. After being cleaned, the plastic fragments are dried and can be processed further.

[0036] Working principle: A clump of plastic film is fed into the feed inlet 4 and falls onto the upper end of the conveyor belt 2. The conveyor belt 2 is started, moving the clump of plastic film to the lower end of the extrusion plate 3. Then, the third telescopic rod 33 is driven to retract. The third telescopic rod 33, through the rectangular plate 32 and the second cylindrical strip 31, moves the extrusion plate 3 downward, extruding the clump of plastic film on the upper end of the conveyor belt 2. This keeps the upper end of the clump of plastic film flat and prevents the clump of plastic film from getting caught on the pointed rod 11 when it slides towards the pointed rod 11, thus preventing it from moving completely. When the rectangular plate 32 moves downward to the lower end of the pointed rod 11, it also drives the L-shaped block 343 to move downward. The L-shaped block 343 drives the cutting blade 34 to move downward through the rectangular tube 341. The cutting blades 34 on both sides of the rectangular plate 32 cut the plastic film at the upper end of the conveyor belt 2. During the cutting, the cutting blade 34 slides into the rectangular tube 341 and squeezes the spring 342 to prevent damage to the lower end of the conveyor belt 2. The clump of plastic film is initially cut to prevent the plastic film from being too long and getting wrapped around the outside of the crushing roller 51 when it enters the crushing box 5 for crushing. Then, the conveyor belt 2 is driven again to transport the clump of plastic film to the lower end of the pointed rod 11. The first telescopic rod 142 is then driven to retract, causing the arc-shaped block 14 to move downwards. The arc-shaped block 14, through the circular slider 112 and the first rectangular strip 111, drives the pointed rod 11 downwards, allowing the first rectangular strip 111 to insert into the clump of plastic film. Simultaneously, the second telescopic rod 153 is driven to retract synchronously with the first telescopic rod 142. The second telescopic rod 153 drives the third rectangular strip 152 to slide downwards. The third rectangular strip 152, through the first cylindrical strip 151, drives the second rectangular strip 15 downwards, causing the second rectangular strip 15 to slide downwards synchronously with the pointed rod 11. At the same time, the arc-shaped block 14 causes the L-shaped rod 143 to abut against the upper end of the rectangular block 22. The length of the L-shaped rod 143 is longer than the length of the pointed rod 11 to prevent the pointed rod 11 from damaging the conveyor belt 2. When the pointed rod 1... After being inserted into the clump of plastic film, the first telescopic rod 142 is kept stationary. Then, the second telescopic rod 153 is driven to retract. The second rectangular rod 15 is driven to slide downward between the two sets of pointed rods 11 through the third rectangular rod 152 and the first cylindrical rod 151. This causes the lower ends of the two sets of pointed rods 11 to move to opposite ends, separating the clump of plastic film. Then, the first telescopic rod 142 and the second telescopic rod 153 are driven to extend, causing the pointed rods 11 to move upward. The second telescopic rod 153 drives the second rectangular rod 15 to move to the upper end of the two sets of pointed rods 11. Since the pointed rods 11 are rotated outside the first cylindrical rod 12 by a torsion spring, when the second rectangular rod 15 moves upward, the pointed rods 11 rotate outside the first cylindrical rod 12, which can reduce the included angle between the upper ends of the two sets of pointed rods 11, making it easier to separate the clump of plastic film next time. The crushed plastic film forms plastic fragments containing dust and impurities, which need to be cleaned before further processing. After being crushed in the crushing box 5, the plastic film falls into the rectangular box 6, which is filled with clean water. Then, the second cylindrical rod 61 is driven to rotate, which in turn drives several levers 62 to rotate in the water. The levers 62 move the plastic fragments in the water, making full contact between the plastic fragments and the water to clean them. After being cleaned and dried, the plastic fragments can be processed further.
