Description

Technical Field

[0001] This invention relates to the field of plastic film waste recycling technology, specifically to a plastic film waste recycling system. Background Technology

[0002] Plastic film waste recycling refers to the entire process of recycling discarded plastic film used in agricultural production, including field collection, impurity removal, crushing and washing, and melting and granulation. The aim is to transform waste plastic film mixed with mud and crop residues into renewable plastic pellets or other resource-based products, thereby reducing white pollution in farmland, reducing the consumption of petroleum-based virgin plastics, and promoting the closed-loop utilization of agricultural non-point source waste into a circular economy.

[0003] The existing patent (publication number: CN119189121A) discloses "a multi-stage separation and recycling method and system for mulch film, including: first screening of a portion of the material as waste and first discharge of the portion of waste separated in the first screening process; first crushing and dispersing of the material after the first discharge; separation of the material and a portion of waste using blowing aid and second discharge of the portion of waste separated in the blowing aid process; and second crushing and friction washing of the material after the second discharge, and second screening of a portion of waste in the material after friction washing to obtain mulch film separated from waste; this application effectively achieves the separation of material and waste through multi-step separation, washing, crushing, dispersing, and friction washing, which is beneficial to resource recycling or reuse."

[0004] In the process of developing this application, the inventors discovered the following problems with the existing technology: the recycling of existing plastic film waste is a long process. The recycled plastic film is usually packaged in rolls, which may contain soil clods and crop residues. The recycled plastic film waste needs to be initially crushed, then the impurities inside are screened, and then the surface is cleaned to complete the recycling. In the existing equipment system, screening and cleaning are carried out using different equipment. The screening equipment usually uses a shaftless drum for screening. The rotation of this drum usually requires an external drive wheel and motor to drive it. These drive structures are usually located in the same equipment shell as the screening drum. During the screening process, there is a lot of dust. Being in this environment for a long time has a great impact on the service life of the drive equipment. The stirring screening equipment with a central shaft has the problem of entanglement, which affects the screening efficiency. Summary of the Invention

[0011] Preferably, the air supply mechanism includes a fan, and an air supply pipe is fixedly installed at the output end of the fan.

[0012] Preferably, the dust collection mechanism includes a bag filter, the dust collection end of which is fixedly connected to a dust collection pipe, and one end of the dust collection pipe is fixedly connected to a dust collection head.

[0013] Preferably, the transmission mechanism includes a second support frame, a conveyor belt is disposed above the second support frame, and a recycling box is connected to one side of the conveyor belt.

[0014] Preferably, the cleaning mechanism includes a water tank, a water pump is installed inside the water tank, a water delivery pipe is fixedly installed at the output end of the water pump, and a water inlet is provided on one side of the upper end of the water tank.

[0015] Preferably, the draining mechanism includes a plate chain conveyor, a third support frame is provided below the plate chain conveyor, a water collection tank is fixedly provided on the surface of the third support frame, and a drain pipe is fixedly provided on one side of the water collection tank.

[0016] Working Principle: During operation, the user places the entire crushing mechanism onto the feed inlet of the recycling mechanism using the first support frame, and connects the bottom of the crushing box to the feed inlet. Then, the user opens the two hinged covers at the top center of the crushing box and feeds the rolled-up mulch film between the two crushing rollers. The motor in the transmission box drives the two crushing rollers to rotate in opposite directions via two meshing gears mounted on the shafts of the two rollers, crushing the mulch film into loose sheets of 15-25cm. During the crushing process, a brush located on the surface above the crushing rollers removes impurities that have become entangled on the roller surface. The brush is placed on a support plate at the top inside the crushing box via a handle, and is controlled from the top of the crushing box. The clamps, secured by bolts, engage with the buckles on both sides of the handle's upper surface to secure the crushed mulch film. The film then flows into the inlet of the recycling mechanism via the connection port. After entering the screening box supported by support legs, a drive motor fixed to the side plate rotates the stirring rod via its output end. This causes multiple evenly spaced stirring blades on the stirring rod to rotate inside the screen, breaking up the mulch film. A protective casing and ventilation holes on the outside of the drive motor ensure proper heat dissipation. Simultaneously, a blower from the air supply mechanism delivers air into the screening box through a duct that passes through holes in the protective cover to assist in screening. The baghouse dust collector from the dust collection mechanism uses a flexible plastic hose... The dust collection pipe and suction head collect and recover the dust generated during the screening process. The screen is fixed at an angle to one side of the sealing plate. The ground film moves along the inner wall of the screen towards the discharge port under the combined action of gravity, stirring blades, and wind. The screen is made of polyurethane-coated metal wire, and its surface has multiple equally spaced screen holes in a conical structure that is wider on the outside and narrower on the inside to prevent the ground film from tangling. The screen holes are divided into three sections with progressively larger apertures, which can screen impurities of different particle sizes step by step. The protective protrusions fixed at equal intervals inside the screen change the contact between the ground film and the screen from surface contact to multi-point contact to reduce the vacuum adsorption effect. At the same time, micro-vibration is generated to prevent the accumulation of adhering material on the wall. The sealing plate, side plate, protective cover, and screening are all integrated into the screen. The boxes are fixed together with bolts and sealing rings are installed at the joints to form a sealed whole recycling mechanism. After screening, the plastic film sheets are transported by the conveyor belt of the transmission mechanism to another recycling mechanism. The recycling box connected to one side of the conveyor belt collects the plastic film sheets that slide off the surface of the conveyor belt. The transmission mechanism is installed in a suitable position by the second support frame. After the plastic film sheets enter the other recycling mechanism, the user adds water to the water tank through the water inlet. The water pump inside the water tank of the cleaning mechanism pressurizes the water and extends it into the screening box through the water pipe through the opening on the upper surface of the protective cover. The water is then sprayed into the screening box through the atomizing nozzle at the end. The stirring blade drives the plastic film sheets to rotate, thus cleaning the impurities on the surface of the plastic film sheets.After being cleaned, the plastic film sheets are discharged from the outlet and fall onto the surface of the dewatering mechanism's chain conveyor for transport. Openings in the chain conveyor allow the moisture contained within the plastic film sheets to flow into a collection tank below. A drain pipe on one side of the collection tank connects the moisture to the municipal water supply network for timely drainage. The chain conveyor is positioned appropriately using a third support frame and requires waterproofing and rustproofing treatment. This process completes the crushing, screening, transporting, cleaning, and dewatering of the plastic film, preparing it for subsequent processing.

[0017] This invention provides a waste plastic film recycling system. It has the following beneficial effects: 1. This invention provides a plastic film waste recycling system. By integrating a crushing mechanism, two recycling mechanisms, a conveying mechanism, an air supply mechanism, a dust collection mechanism, a cleaning mechanism, and a draining mechanism, it achieves integrated operation of crushing, screening, conveying, cleaning, and draining of plastic film waste, effectively shortening the recycling process and reducing the types of equipment required. At the same time, the air supply mechanism assists in screening during the screening process and works with the dust collection mechanism to collect floating dust in the device, reducing the dust concentration in the screening environment and thus reducing the adverse effects of dust on the service life of the drive equipment. Furthermore, by setting protective protrusions inside the screen, the plastic film sheet and the screen are changed from surface contact to multi-point contact to reduce the vacuum adsorption effect and generate micro-vibration to prevent the accumulation of residue on the wall. The use of stirring blades reduces the adhesion of the plastic film sheet and the use of connecting plates to further prevent entanglement, which significantly improves the screening efficiency and solves the problem of easy entanglement in existing stirring screening equipment.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1-2 As shown, this embodiment of the invention provides a plastic film waste recycling system, including two recycling mechanisms 1, a transmission mechanism 5 between the two recycling mechanisms 1, a crushing mechanism 2 on one side of the two recycling mechanisms 1, a draining mechanism 7 on the other side of the two recycling mechanisms 1, an air supply mechanism 3 and a dust suction mechanism 4 on the upper end of one of the two recycling mechanisms 1, and a cleaning mechanism 6 on the upper end of the other of the two recycling mechanisms 1.

[0022] Specifically, during use, the plastic film is initially crushed by the crushing mechanism 2, then initially screened by the first recycling mechanism 1 in conjunction with the air supply mechanism 3 and the dust collection mechanism 4, and then transported by the transmission mechanism 5 to the second recycling mechanism 1, where it is cleaned by the cleaning mechanism 6. After cleaning, it is drained by the draining mechanism 7 for subsequent processing.

[0023] like Figure 3-4 As shown, the crushing mechanism 2 includes a first support frame 203. A crushing box 201 is fixedly installed on the upper end of the first support frame 203. A connection port 202 is fixedly installed on the bottom end of the crushing box 201. Two crushing rollers 206 are rotatably installed inside the crushing box 201. A transmission box 205 is fixedly installed on one side of the crushing box 201. The transmission box 205 and the crushing rollers 206 are fixedly connected. Two cover plates 204 are hinged at the middle position of the upper end of the crushing box 201. A support plate 211 is fixedly installed on the upper end of the inside of the crushing box 201. A handle 210 is connected to the surface of the support plate 211. A brush 209 is fixedly installed below the handle 210. Buckles 208 are fixedly installed on both sides of the upper surface of the handle 210. Multiple clamping plates 207 are bolted to the upper end of the crushing box 201.

[0024] Specifically, most of the plastic film currently being recycled is in roll form. During recycling, it usually needs to be initially crushed into loose sheets of 15-25cm to screen out impurities. In this application, the crushing mechanism 2 mainly functions to crush the roll of plastic film into relatively small sheets. When in use, the user can place the crushing mechanism 2 as a whole at one end of the feed inlet 102 of the recycling mechanism 1 through the first support frame 203, connect the lower connection port 202 to the feed inlet 102, open the cover plate 204, and feed the roll of plastic film between the two crushing rollers 206. One end of the two crushing rollers 206 is connected to a transmission box 205, which contains a motor and two gears. The two gears are respectively sleeved on the shafts of the two crushing rollers 206 and mesh with each other. The motor output is connected to one of the two crushing rollers 206. The two crushing rollers 206 rotate in opposite directions through gear meshing to achieve the function of crushing the plastic film. The crushing box 201 is equipped with a clamping plate 207 sleeved on the bolts. The handle 210 is equipped with a buckle 208 at the corresponding position. The handle 210 is placed on the support plate 211. The brush 209 is located on the upper surface of the crushing roller 206. During the crushing process, the clamping plate 207 is tightened and fixed by the bolts, which forms a snap-fit ​​with the buckle 208 and fixes the brush 209. The brush 209 can remove impurities wrapped around the surface of the crushing roller 206 to ensure stable operation of the equipment. After use, the bolts need to be loosened, the clamping plate 207 needs to be rotated to release the fixation, and the brush 209 can be removed and disposed of or replaced through the handle 210 to ensure that it can perform its function normally.

[0025] like Figure 5-6As shown, the recycling mechanism 1 includes a screening box 103. A protective cover 101 is fixedly installed on the upper end of the screening box 103 by bolts. A sealing plate 105 is fixedly installed on one end of the screening box 103 and the protective cover 101 by bolts. A screen 109 is fixedly installed on one side of the sealing plate 105 by bolts. A feed inlet 102 is fixedly installed on one side of the side plate 107. A discharge outlet 106 is fixedly installed on one side of the sealing plate 105. A support leg 104 is fixedly installed on the outside of the screening box 103.

[0026] Specifically, the screening box 103 has three recovery ports at its bottom. Combined with the three-section design of the screen 109, impurities can be removed step by step according to particle size. The protective cover 101 has multiple openings on its surface, allowing different equipment to be installed for different functions of the recovery mechanism 1. In this application, the first recovery mechanism 1 is equipped with an air supply mechanism 3 and a dust collection mechanism 4, which combine airflow to screen the mulch film. The second recovery mechanism 1 is equipped with a cleaning mechanism 6 to clean impurities from the surface of the mulch film. This design allows the structures of the screening and cleaning parts to be interchangeable, and some parts of the equipment with different functions to be interchangeable, facilitating subsequent maintenance and saving costs. (The sealing plate 105 is also mentioned.) The side plate 107 is fixed together with the protective cover 101 and the screening box 103 by bolts. Sealing rings are provided at the connection points to make the entire recycling mechanism 1 a sealed whole. In use, the mulch film only needs to be put into the feed port 102 to get the processed mulch film from the discharge port 106. The screen 109 is fixed to the sealing plate 105, and the drive motor 113 is fixed to the side plate 107. If the two structures are damaged after long-term use, the corresponding sealing plate 105 or side plate 107 can be removed to take out the screen 109 or stirring rod 114 for easy maintenance and replacement. The support leg 104 can provide support for the entire recycling mechanism 1 so that it can be placed in a suitable position for use.

[0027] like Figure 10 As shown, the screen 109 has multiple protective protrusions 110 fixedly arranged at equal intervals inside, and multiple screen holes 111 are opened at equal intervals on the surface of the screen 109. The multiple screen holes 111 are conical with a wider outer side and a narrower inner side.

[0028] Specifically, in this application, the screen 109 is set at a certain angle on one side of the sealing plate 105 to ensure that during the screening process, the ground film can move along the inner wall of the screen 109 towards the discharge port 106 by gravity and the driving force of the stirring blade 108. The screen 109 is made of polyurethane-coated metal wire, which has good elasticity and can ensure sufficient screening. The polyurethane can also reduce adhesion and prevent the ground film from sticking to the surface of the screen 109 and being difficult to remove. The screen holes 111 on the surface of the screen 109 are divided into three sections, with the hole diameter gradually increasing. The screen size is increased, and combined with the three openings at the bottom of the screening box 103, impurities of different particle sizes can be screened step by step. The screen holes 111 have a cone-shaped structure with a larger outer diameter and a smaller inner diameter, which can prevent the mulch film from getting tangled at the screen holes 111. At the same time, by adding protective protrusions 110 inside the screen mesh 109, the mulch film and the screen mesh 109 are changed from surface contact to multi-point contact, reducing the vacuum adsorption effect. At the same time, the protective protrusions 110 can generate micro-vibration on the mulch film, preventing the accumulation of residue on the wall, and further ensuring that the mulch film can be completely discharged outside the recycling mechanism 1.

[0029] like Figure 11 As shown, a side plate 107 is fixedly installed at one end of the screening box 103, a drive motor 113 is fixedly installed on one side surface of the side plate 107, a stirring rod 114 is fixedly installed at the output end of the drive motor 113, a plurality of stirring blades 108 are fixedly installed at equal intervals on the surface of the stirring rod 114, and a protective box 112 is installed on the outside of the drive motor 113, and heat dissipation holes are opened on the surface of the protective box 112.

[0030] Specifically, during use, the drive motor 113 drives the stirring blades 108 on its surface to rotate within the screen 109 via the stirring rod 114. The drive motor 113 and stirring rod 114, together with the screen 109, are inclined to a certain extent to break up and separate the mulch film inside the screen 109. The stirring blades 108 are made of rubber. Unlike traditional rubber breaking teeth, the breaking part of the stirring blades 108 in this application is arc-shaped along the flow direction of the mulch film, which can reduce the adhesion of the mulch film. At the same time, a connecting plate is provided between the breaking part of the stirring blades 108 and the stirring rod 114 to further prevent entanglement. The protective box 112 mainly serves to protect the drive motor 113. Combined with the heat dissipation holes on its surface, it can ensure the normal heat dissipation of the drive motor 113 and ensure the normal operation of the device.

[0031] like Figure 5 As shown, the air supply mechanism 3 includes a fan 301, and an air supply pipe 302 is fixedly installed at the output end of the fan 301.

[0032] Specifically, the air supply duct 302 is connected to the interior of the recycling mechanism 1 through holes opened on the surface of the protective cover 101. The fan 301 delivers air to the recycling mechanism 1. While the recycling mechanism 1 is being stirred and screened, the air supply mechanism 3 assists in further screening by supplying air, thereby improving the screening effect of the first recycling mechanism 1. At the same time, it can also work with the dust collection mechanism 4 to quickly collect and process the dust floating inside the device, reducing its impact on the surrounding environment.

[0033] like Figure 6 As shown, the dust collection mechanism 4 includes a bag dust collector 401, a dust collection pipe 402 is fixedly connected to the dust collection end of the bag dust collector 401, and a dust collection head 403 is fixedly connected to one end of the dust collection pipe 402.

[0034] Specifically, the main internal structure of the bag filter 401 consists of a fan for dust collection and a matching dust collection bag. During use, the suction head 403 at the bottom is connected to the bag filter 401 through a dust collection pipe 402. The dust collection pipe 402 is in the form of a plastic flexible hose, and its length and position can be adjusted to a certain extent. It can also be replaced after prolonged use when it becomes clogged. The suction head 403 is in the form of a conventional vacuum cleaner head. When used with the suction fan, it can suck up dust from a certain width. In this application, its width is slightly larger than the width of the discharge port 106, and it can suck up the dust generated by screening in the first recycling mechanism 1.

[0035] like Figure 7 As shown, the transmission mechanism 5 includes a second support frame 502, a conveyor belt 501 is arranged above the second support frame 502, and a recycling box 503 is connected to one side of the conveyor belt 501.

[0036] Specifically, the second support frame provides support for the entire transmission mechanism 5 to be installed in a suitable position. The transmission mechanism 5 transports the mulch film sheets that have been screened in the first recycling mechanism 1 to the second recycling mechanism 1 for cleaning via the conveyor belt 501. The recycling box 503 connected to one side is used to collect the mulch film sheets that slide off the surface of the conveyor belt 501 to prevent them from falling out of the system. The length, position and shape of the entire transmission mechanism 5 can be adjusted according to the actual use. The example shown in this application is only a conventional use example.

[0037] like Figure 8 As shown, the cleaning mechanism 6 includes a water tank 602, a water pump is installed inside the water tank 602, a water delivery pipe 603 is fixedly installed at the output end of the water pump, and a water inlet 601 is provided on one side of the upper end of the water tank 602.

[0038] Specifically, the cleaning mechanism 6 mainly includes a water tank 602 and a water pump located inside the water tank 602. The output end of the water pump is connected to a water supply pipe 603. The water supply pipe 603 passes through the opening on the upper surface of the protective cover 101 and extends into the recycling mechanism 1. One end of the water supply pipe 603 extending into the recycling mechanism 1 is connected to a nozzle. When in use, the user can add water to the water tank 602 through the water inlet 601. After the water pump pressurizes the water in the water tank 602, it is sprayed into the recycling mechanism 1 through the water supply pipe 603 and the atomizing nozzle. The recycling mechanism 1 drives the ground film to rotate, and the water mist cleans the ground film.

[0039] like Figure 9 As shown, the draining mechanism 7 includes a plate chain conveyor 701, a third support frame 704 is provided below the plate chain conveyor 701, a water collection tank 702 is fixedly provided on the surface of the third support frame 704, and a drain pipe 703 is fixedly provided on one side of the water collection tank 702.

[0040] Specifically, during use, the cleaned plastic film sheets are discharged from the outlet 106 of the second recycling mechanism 1 onto the surface of the draining mechanism 7. The draining mechanism 7 uses a plate chain conveyor 701 as the main transport mechanism. The plate chain openings on the surface of the plate chain conveyor 701 ensure that the water contained in the plastic film sheets flows into the water collection tank 702 below while the plastic film sheets are being transported. The water in the water collection tank 702 can be discharged in a timely manner by connecting the drain pipe 703 to the municipal pipe network. When connecting the equipment, the plate chain conveyor 701 needs to be waterproofed and rustproofed. The entire draining mechanism 7 is placed in a suitable position by the third support frame 704. During use, the user can also clamp drying equipment on the draining mechanism 7 to further improve the draining effect. The relevant technology is a mature technology in this field, and its specific principle is not an innovation of this application, so it will not be described in detail here.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
