Description

Technical Field

[0001] The invention relates to the technical field of waste plastic recycling, in particular to a waste EVA plastic film recycling mechanism. Background Art

[0002] The waste EVA plastic film recycling mechanism is a device for recycling waste EVA plastic film. It recycles waste plastics to meet the needs of subsequent processing. It usually breaks the waste plastics into small flakes or particles, and then removes impurities, dirt and adhesives on the surface of the film.

[0003] In the prior art, when recycling discarded EVA plastic films, the crushing effect of large pieces of EVA plastic films is affected by the shape of the crushing roller, which easily leads to poor crushing effect.

[0004] In order to overcome the above-mentioned shortcomings, a Chinese patent of the prior art (publication number CN115716311A) discloses a waste plastic film recycling and shredding device and a shredding method thereof. The waste plastic film recycling and shredding device includes a base plate, the upper end surface of the base plate is fixedly connected to a shredding box through a fixed frame, the inside of the shredding box is connected to a mounting cylinder which is symmetrically rotated left and right through a rotating shaft, and a plurality of shredding tooth plates are evenly fixedly connected to the outer wall of the mounting cylinder in a circumferential direction. A dust removal mechanism is installed at the lower part of the shredding box, and an arc-shaped pressure block for cooperating with the pressure plate is fixedly connected to the upper part of the rear end surface of the circular cover. The plastic film wrapped around the outside of the mounting cylinder and the shredding tooth plate can be cut off in time through the slitting mechanism and the cutting mechanism, thereby avoiding the damage of the equipment caused by winding and ensuring the normal progress of the shredding work. The dust removal mechanism can also peel off and separate the dust mixed in the plastic film fragments, thereby improving the shredding quality.

[0005] In order to overcome the above-mentioned shortcomings, the Chinese patent of the prior art (publication number CN106994756A) discloses a plastic film waste recycling and processing device, which includes a crushing device, a cooling device, a drying device, a particle forming device and a collection box. The cooling device is located between the crushing device and the drying device, the drying device is located between the cooling device and the particle forming device, and the particle forming device is located between the drying device and the collection box. This device can recycle discarded plastic film, and then reprocess it to form reusable granular plastic. The granules can be used to produce film again, thereby achieving the purpose of reusing waste film, which not only saves resources but also saves costs and brings many conveniences to users.

[0006] Although the existing technology can overcome the above-mentioned shortcomings, there are still other problems in its operation process. For example, when recycling the waste EVA plastic film, after the waste EVA plastic film is broken into fine particles, it is easy to adhere to the inner wall of the device. Since it adheres to the inside of the device, it is inconvenient for the staff to take it out. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1: Figures 1-6The technical solution shown is a waste EVA plastic film recycling mechanism. In order to solve the problem that fine particles are easily retained inside the device when the waste EVA plastic film is recycled, the following is disclosed: a body 1 and a feed port 2 installed at the upper end of the body 1, two crushing rollers 3 are rotatably arranged inside the body 1, and the left side of the front crushing roller 3 is driven by a motor, and the right ends of the front and rear crushing rollers 3 are meshed by gears, a storage plate 4 is fixedly installed on the inner wall of the body 1, a sealing door 5 is installed at the front end of the body 1, a mounting bin 14 is installed on the right side of the body 1, and an anti-sticking cleaning mechanism is provided at the upper end of the storage plate 4, a discharge port 6 is provided at the right end of the storage plate 4, and a sealing plate 8 is nested and installed inside the discharge port 6, and the shape of the sealing plate 8 is "L" shaped, and the right end of the sealing plate 8 is installed with the output end of the electric telescopic rod 7, and the left side of the electric telescopic rod 7 is fixedly installed on the right side of the body 1, an inclined plate is installed on the upper end of the storage plate 4, and the left side of the inclined plate is in contact with the inner wall of the body 1, and The right side of the inclined plate corresponds to the discharge port 6, the anti-sticking cleaning mechanism is provided with a water spray port 17, and the right side of the water spray port 17 is installed on the right side of the body 1 through the connecting plate 18, and the output end of the water spray port 17 is aligned with the top of the storage plate 4, the right side of the water spray port 17 is connected to the inside of the installation bin 14 through the connecting conduit 16, and the middle end of the connecting conduit 16 is provided with a water pump, the inner wall of the body 1 is fixedly installed with a first filter plate 9, and the front end of the first filter plate 9 is correspondingly provided with a sealing door 5, the right bottom of the body 1 A second filter plate 15 is installed on the body 1, and the second filter plate 15 is located at the left opening position of the installation bin 14. A driving rod 10 is rotatably installed on the left side of the body 1, and the driving rod 10 forms a synchronous rotation structure with the driving motor through a belt and a pulley, and an auxiliary cleaning rod 12 is installed on the right end of the driving rod 10 through a bevel gear set 11. The bottom of the auxiliary cleaning rod 12 is located above the first filter plate 9, and an isolation box is provided on the outside of the bevel gear set 11. The bottom of the body 1 is connected to an electronic drain valve 13.

[0035] When recycling waste EVA plastic film, the waste EVA plastic film is put into the feed port 2 of the machine body 1, and the waste EVA plastic film after being put into the machine body falls on the surface of the crushing roller 3. At this time, the crushing roller 3 is started by the motor, and the front and rear crushing rollers 3 are meshed with each other through gears and can rotate synchronously, so that the waste EVA plastic film can be crushed. The crushed particles fall on the upper end of the sealing door 5. After the crushing is completed, the crushed waste EVA plastic film can be taken out by opening the sealing door 5 for recycling. Figure 4As shown, if it is necessary to clean the residual waste EVA plastic film, or to clean the crushed waste EVA plastic film, an appropriate amount of water source is added to the inside of the machine body 1. The water source is stored inside the machine body 1. When it is needed, the water pump connected to the upper end of the installation bin 14 is started, and the water source is delivered to the water nozzle 17 through the water pump box connecting conduit 16. The water nozzle 17 sprays water at the upper end of the storage plate 4. At this time, the electric telescopic rod 7 is started. The start of the electric telescopic rod 7 can drive the sealing plate 8 to move. The sealing plate 8 is pulled to the right and the sealing of the discharge port 6 is stopped. At this time, the crushed waste EVA plastic film is carried by the water flow along the inclined plate on the storage plate 4 and falls onto the surface of the first filter plate 9. At this time, as the crushing roller 3 continues to work, the driving motor that drives the crushing roller 3 drives the driving rod through the belt and pulley. 10 rotates, and when the driving rod 10 rotates, it drives the auxiliary cleaning rod 12 to rotate through the bevel gear set 11 inside the isolation box, and at this time drives the water flow to stir, and the water flow carries the crushed waste EVA plastic film particles to rotate and clean, so that the impurities on the surface of the waste EVA plastic film particles pass through the first filter plate 9 and fall into the bottom of the body 1. At the same time, the grid density of the second filter plate 15 is greater than that of the first filter plate 9, so that the impurities are precipitated at the bottom of the body 1 due to gravity. The continuous water spraying from the water nozzle 17 can prevent the crushed waste EVA plastic film from remaining inside the body 1, and the crushed waste EVA plastic film can be cleaned as needed. The sewage impurities after cleaning can be filtered and reused. When it is not needed, the sewage can be discharged from the body 1 along the electronic drain valve 13.

[0036] Example 2: Figures 1-9 The technical solution shown is based on Example 1 and, in order to solve the problem of narrow angle when cleaning residual waste EVA plastic film particles, it is disclosed that: a protective box 19 is installed at the upper right end of the body 1, and an angle adjustment mechanism is provided at the lower end of the protective box 19, the angle adjustment mechanism is provided with a cam 20, and the cam 20 is fixedly installed at the right end of the front crushing roller 3, the lower end of the protective box 19 is nested with a lifting plate 21, and the upper end of the lifting plate 21 corresponds to the cam 20, and the upper end of the lifting plate 21 is inclined, the lower end of the lifting plate 21 is rotatably installed with a telescopic plate 23, and the lower end of the telescopic plate 23 is slidably connected to the inside of the connecting plate 18, and the front and rear ends of the connecting plate 18 are rotatably connected to the body 1, the middle end of the lifting plate 21 is installed with a return spring 22 through a partition, and the upper end of the return spring 22 is fixedly installed at the lower end of the protective box 19.

[0037] As water is sprayed from the water nozzle 17, the front crushing roller 3 rotates, and the right end of the front crushing roller 3 rotates to drive the cam 20 on the surface. The cam 20 rotates inside the protective box 19 to rotate and squeeze the lifting plate 21. When the lifting plate 21 is squeezed, it can drop to push the return spring 22, and the descent of the lifting plate 21 pushes the telescopic plate 23. The telescopic plate 23 slides inside the connecting plate 18 and drives the connecting plate 18 rotatably mounted with the body 1. The rotation of the connecting plate 18 drives the angle of the water nozzle 17 to change, so that the water nozzle 17 can swing back and forth for angle adjustment, further improving the range of water spraying, and when the upward inclination of the water nozzle 17 reaches the highest, the crushing roller 3 can also be cleaned by water spraying to avoid the crushed waste EVA plastic film remaining on the surface of the crushing roller 3.

[0038] Example 3: Figures 1-11 The technical solution shown is based on the second embodiment. In order to solve the problem of incomplete cleaning of the surface of the crushing roller 3, the following is disclosed: a positioning member 25 is installed at the right end of the protective box 19, and an auxiliary airflow mechanism is provided inside the positioning member 25. The auxiliary airflow mechanism is provided with an airflow chamber 24, and the airflow chamber 24 is opened inside the crushing roller 3, and holes are evenly spaced on the surface of the crushing roller 3, and the holes are connected to the airflow chamber 24 inside the crushing roller 3. The right side of the crushing roller 3 is docked with the left end of the positioning member 25 through a bearing, and an electric fan 26 is installed inside the positioning member 25, and the electric fan 26 is an air suction fan. A dustproof net 27 is installed at the right end of the positioning member 25, and a connecting rod is installed through the middle end of the dustproof net 27, and the left side of the connecting rod is fixedly installed on the central axis of the electric fan 26, and a rotating rod 28 is fixedly installed on the right end of the connecting rod. A cleaning brush 29 is fixedly installed inside the rotating rod 28 through a pressure spring 30, and the left side of the cleaning brush 29 is in contact with the surface of the dustproof net 27.

[0039] A positioning member 25 is provided inside the protection box 19. The positioning member 25 is funnel-shaped. The left end of the positioning member 25 is connected to the inside of the rotating crushing roller 3 through a bearing. Figure 10 As shown, by starting the electric fan 26, the electric fan 26 sucks air when it rotates, and the sucked air passes through the dustproof net 27 to filter the dust, so that the air flows along the inside of the positioning member 25 into the air flow cavity 24 inside the crushing roller 3. The air entering the air flow cavity 24 is discharged from the holes opened on the surface of the crushing roller 3, thereby cleaning the waste EVA plastic film particles remaining on the surface of the crushing roller 3, which can further improve the effect of cleaning the surface of the crushing roller 3. Figure 11As shown, as the electric fan 26 rotates, the electric fan 26 drives the rotating rod 28 to rotate through the connecting rod. The rotation of the rotating rod 28 can drive the cleaning brush 29 on the inside. Under the setting of the pressure spring 30, the cleaning brush 29 can fit the surface of the dustproof net 27, so as to clean the dustproof net 27, avoid the dustproof net 27 from being blocked and affecting the air intake efficiency, and ensure the stability of the device.
