Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, and more specifically, to a waste treatment device for the preparation of antibacterial PE preservation film. Background Technology

[0002] As consumers demand higher food safety and preservation performance, antibacterial polyethylene (PE) preservation film, which contains antibacterial ingredients such as nano silver and quaternary ammonium salts to inhibit microbial growth, has become an important product in the food packaging field. However, during the production process, especially when using multi-layer co-extrusion, operations such as die cutting and equipment start-up and shutdown will generate scrap and defective products. These wastes contain metallic antibacterial agents and cannot be directly degraded or landfilled, requiring special recycling treatment.

[0003] Currently, the main recycling method for antibacterial PE cling film waste is the mechanical-physical method, which mainly includes two steps: First, the waste is crushed by crushing equipment and dried to remove surface moisture; then, the pre-treated material is fed into a single-screw extruder for melt extrusion to form recycled granules. In order to improve recycling efficiency and safety, a negative pressure conveying system is usually equipped to collect scraps, and a screening device is used to remove metal impurities to improve the purity of recycled materials.

[0004] Although this method partially realizes the resource utilization of waste, it still faces technical challenges in practical applications. For example, when different types of antibacterial systems are mixed, insoluble precipitates may be generated due to chemical reactions between components. These precipitates are prone to accumulate in the extrusion system, causing filter clogging, affecting the stability of equipment operation, and increasing maintenance requirements. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a waste treatment device for the preparation of antibacterial PE preservation film, which aims to solve the above-mentioned technical problems.

[0011] As a further aspect of the present invention: a sealing assembly is provided at the bottom of the storage cylinder, the sealing assembly including a fourth servo motor fixedly connected to the front side of the outer surface of the processing box, the output end of the fourth servo motor being fixedly connected to a second rotating rod through the processing box, a support rod being fixedly connected to the outer circular surface of the second rotating rod, and an arc-shaped cover being fixedly connected to the top of the support rod; the blower assembly includes an air guide tube fixedly connected to the middle of the bottom of the processing box, a vent hood being fixedly connected to the air guide tube through the inside of the processing box, a motor being fixedly connected to the middle of the inside of the air guide tube, and a fan being fixedly connected to the output end of the motor.

[0012] As a further aspect of the present invention: both sides of the bottom of the processing box are provided with recycling mechanisms for collecting different types of antibacterial waste. The recycling mechanism includes an L-shaped plate fixedly connected to both sides of the bottom of the processing box. A first hydraulic rod is fixedly connected to the upper surface of the inner side of the L-shaped plate. A support plate is fixedly connected to the top of the first hydraulic rod. A receiving pipe is fixedly connected to one side of the support plate. Both sides of the bottom of the processing box are provided with discharge ports that are adapted to the outer diameter of the receiving pipe. An extension pipe is fixedly connected to the bottom of the outer circular surface of the receiving pipe. A blocking plate is provided at the top of the receiving pipe. A second hydraulic rod fixedly connected to the receiving pipe is provided at the middle of the bottom of the blocking plate.

[0013] As a further aspect of the present invention: the crushing mechanism includes side plates fixedly connected to both sides of the outer surface of the funnel cylinder; a first drive rod and a second drive rod are rotatably connected inside the funnel cylinder; the first drive rod and the second drive rod both penetrate the side plates and are respectively fixedly connected to a first gear and a second gear; one end of the first drive rod is provided with a third servo motor fixedly connected to the side plate; shearing components are provided on the outer circular surfaces of the first drive rod and the second drive rod; the shearing components include a threaded sleeve fixedly connected to the outer circular surface of the second drive rod; a crushing roller fixedly connected to the second drive rod is provided on the outer circular surface of the threaded sleeve; and a cooling pipe threadedly connected to the threaded sleeve is provided on the inner side of the crushing roller.

[0014] As a further aspect of the present invention: the conveying mechanism includes a flow pipe disposed at the bottom of the take-up roller, and square slots are provided on both sides of the upper surface of the flow pipe; a double-headed conveying pump fixedly connected to the frame is provided on one side of the flow pipe, one end of the double-headed conveying pump is provided with a connecting pipe communicating with the flow pipe, and the other end of the double-headed conveying pump is provided with a conveying pipe communicating with the funnel cylinder.

[0015] As a further aspect of the present invention: the conveying mechanism further includes a control module, the control module being configured with:

[0016] The waste conveying control unit is used to receive real-time monitoring signals of the waste accumulation status at the inlet of the flow pipe. When it is determined that the waste accumulation status has reached the preset control conditions, it sends a rate adjustment command to the dual-head conveying pump to match the flow rate rhythm of the waste entering the flow pipe.

[0017] The temperature and humidity co-control unit is used to receive temperature and humidity detection signals inside the processing chamber. When the temperature is detected to be outside the crushing processing range, it sends a cooling start signal to the cold air delivery pump to maintain the low temperature environment of the processing chamber. When the humidity is detected to be below the interlayer separation range, it sends an intermittent warm water supply signal to the media supply module to drive the phased delivery of warm water into the storage cylinder.

[0018] The adsorption intensity dynamic adjustment unit is used to receive the wind speed detection signal of the blower assembly, generate adsorption intensity adjustment parameters based on the wind speed change characteristics, and send the parameters to the first adsorption assembly and the second adsorption assembly respectively, so as to realize the adaptive control of electrostatic adsorption intensity and wind speed change.

[0019] As a further aspect of the present invention: the processing box is equipped with a temperature and humidity detection component, the temperature and humidity detection component comprising:

[0020] The signal acquisition module is used to acquire real-time temperature data of the upper processing area through the temperature sensor integrated in the processing box, and at the same time acquire humidity data around the storage cylinder through the humidity sensor, generating a multi-source monitoring signal that integrates the crushing environment temperature and interlayer separation humidity conditions.

[0021] The intelligent analysis module is used to receive the multi-source monitoring signals, and through logical analysis of the deviation value between the temperature data and the crushing processing adaptation range, and the difference between the humidity data and the interlayer separation adaptation range, output a status judgment result including the temperature exceeding the limit and the humidity insufficient level.

[0022] The execution control module is used to perform response operations based on the status determination result.

[0023] As a further aspect of the present invention: the execution control module is used to perform a response operation based on the state determination result, specifically including:

[0024] When a temperature over-limit indicator is received, a cooling start signal is sent to the cold air delivery pump to control the cold air delivery pump to deliver cold air into the processing box until the temperature data fed back by the temperature sensor falls back to the crushing processing range.

[0025] When a humidity level of insufficient is received, an intermittent warm water supply signal is sent to the media supply module. By adjusting the valve opening and closing frequency and duration of the media supply module, warm water is delivered to the storage cylinder in stages until the humidity data fed back by the humidity sensor reaches the interlayer separation adaptation range.

[0026] When the temperature and humidity are both within their respective suitable ranges, a standby signal is sent to the cold air delivery pump and the media supply module.

[0027] The closed-loop verification module continuously receives real-time data from the temperature and humidity detection components, dynamically adjusts the cooling capacity parameters of the cold air delivery pump and the warm water supply parameters of the media supply module based on data changes, and sends the adjusted parameters back to the execution control module to maintain the stability of the environment inside the processing chamber.

[0028] As a further aspect of the present invention: a guiding mechanism for guiding waste material is provided directly above the take-up roller. The guiding mechanism includes a second servo motor fixedly connected to one side of the outer surface of the frame. The output shaft of the second servo motor is fixedly connected to a turntable. A connecting plate is fixedly connected to the top of the turntable. A limiting cylinder is fixedly connected to the bottom of the connecting plate. A first servo motor is fixedly connected to one side of the outer surface of the limiting cylinder. A first rotating rod is fixedly connected to the output end of the first servo motor. An adsorption cylinder is fixedly connected to the first rotating rod through the limiting cylinder. A plurality of adsorption holes are opened at the bottom of the adsorption cylinder. A connecting box is fixedly connected to the top of the adsorption cylinder. A first air pump for providing suction to the adsorption cylinder is provided on one side of the outer surface of the limiting cylinder.

[0029] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0030] This solution incorporates a storage mechanism, a blower assembly, a separation mechanism, and a media supply module. In the upper processing zone of the processing chamber, the film is crushed into fragments by a crushing mechanism. The media supply module then supplies processing media for pretreatment to reduce chemical reactivity. The pretreated fragments enter the lower separation zone, where they are dispersed and lifted by the blower assembly. The first and second adsorption components of the separation mechanism then classify and separate the fragments based on their physical properties. This process effectively recycles and classifies antibacterial PE preservation film waste, avoiding the problems of sedimentation, equipment blockage, and increased maintenance costs associated with mixing different antibacterial systems. It also improves recycling efficiency and equipment operational stability.

[0031] By incorporating a storage mechanism, a cold air delivery pump, a sealing assembly, and a blower assembly, waste materials are conveyed into the processing area of ​​the processing tank via a conveyor mechanism. After being guided by the conical hood of the storage mechanism and collected in a funnel, the waste is crushed by the crushing mechanism. A sealing plate controls whether the crushed membrane is temporarily stored or falls into the storage cylinder. The cold air delivery pump maintains a low-temperature environment and, in conjunction with the media supply module, performs cold brittleness and warm water soaking pretreatment on the crushed membrane. The arc-shaped cover of the sealing assembly controls the entry of the crushed membrane into the lower separation zone. The blower assembly disperses the crushed membrane to facilitate the separation process by the separation mechanism. This achieves a smooth transition from waste crushing to separation, avoiding the precipitation caused by mixing different antibacterial systems and laying a solid foundation for the subsequent efficient recycling of waste materials from different antibacterial systems.

[0032] By setting up a crushing mechanism, the first drive rod is driven to rotate by a third servo motor. The meshing transmission between the first and second gears drives the second drive rod to rotate in the opposite direction, so that the two sets of crushing rollers form a shearing relationship to cut the waste into fine fragments. At the same time, the cooling pipes inside the crushing rollers are circulated with cooling medium to absorb heat. Combined with the low-temperature environment inside the treatment chamber, the waste is crushed into fragments that meet the requirements of subsequent processing. This avoids the enhanced activity of antibacterial components in the fragments due to high temperature, and ensures the chemical stability of the crushed waste. Attached Figure Description

[0054] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0055] The waste treatment device for the preparation of antibacterial PE preservation film provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0056] like Figures 1 to 9 As shown, this embodiment of the invention provides a waste treatment device for the preparation of antibacterial PE preservation film, including a frame 1, a winding roller 2 is provided on one side of the inside of the frame 1, and a treatment box 5 is provided on the outside of the frame 1. A conveying mechanism 4 is provided at the bottom of the winding roller 2 for conveying waste to the treatment box 5. A partition plate 6 is fixedly connected inside the treatment box 5, dividing the treatment box 5 into an upper treatment area and a lower separation area. The upper treatment area is provided with a storage mechanism 7, which includes a storage cylinder 72. A medium supply module 10 is provided on one side of the outer surface of the treatment box 5 for supplying treatment medium to the storage cylinder 72. A crushing mechanism 8 is provided at the top inside the storage cylinder 72. The lower separation area is provided with a blower assembly 12 and a separation mechanism 13 for dispersing and separating the crushed waste.

[0057] The separation mechanism 13 includes a first adsorption assembly 131 and a second adsorption assembly 132 located on both sides of the bottom of the processing box 5. The second adsorption assembly 132 includes a second air pump 1325 fixed to the outer surface of the processing box 5. One end of the second air pump 1325 is fixedly connected to a duct 1326, and the other end passes through the processing box 5 and is fixedly connected to a coiled tube 1321. The surface of the coiled tube 1321 is provided with ventilation holes 1322. A top cover 1324 fixedly connected to the processing box 5 is provided directly above the coiled tube 1321, and a partition cover 1323 fixedly connected to the top cover 1324 is fitted on the outer surface of the coiled tube 1321.

[0058] The media supply module 10 pre-treats the crushed waste containing different antibacterial systems to reduce the chemical reactivity between components. Then, the blower assembly 12 disperses the pre-treated waste and utilizes the differences in physical properties of different types of antibacterial system waste to cooperate with the corresponding action structures of the first adsorption assembly 131 and the second adsorption assembly 132 to complete the classification and separation of different types of antibacterial membranes.

[0059] To address the problem that mixing different antibacterial systems in the recycling of existing antibacterial PE cling film waste can easily lead to chemical reactions that generate precipitates, causing equipment blockage and increased maintenance costs, the above-mentioned technical solution is adopted. This technical solution mainly consists of a conveying mechanism 4, a processing box 5, a storage mechanism 7, a crushing mechanism 8, a blower assembly 12, a separation mechanism 13, and a media supply module 10. Its working principle is as follows: First, the corner waste generated by the winding roller 2 inside the frame 1 during the production process will fall into the conveying mechanism 4 at its bottom. The conveying mechanism 4 will transport the waste to the processing box 5 outside the frame 1. The processing box 5 is divided into an upper processing area and a lower separation area by the internal partition plate 6, so that the waste can be processed in stages according to the process. After the waste enters the upper processing area of ​​the processing box 5, it first enters the corresponding area of ​​the storage mechanism 7. The crushing mechanism 8 at the top of the storage cylinder 72 crushes the waste into fragments that are easy to process later. The crushed fragments are temporarily stored in the storage cylinder 72. At this time, the media supply module 10 on the outer surface of the processing box 5 supplies processing media (such as warm water) into the storage cylinder 72 to pre-treat the fragments. The impact of warm water on the fragments can induce the propagation of microcracks between different layers of the membrane, while reducing the chemical reactivity between different antibacterial system components, thus reducing the formation of insoluble precipitates from the source. After pretreatment, the membrane fragments enter the lower separation zone of the treatment chamber 5. The blower assembly 12 in the lower separation zone starts working, generating airflow to blow and lift the membrane fragments, allowing them to be fully dispersed in the space, creating conditions for subsequent classification and separation. Subsequently, the separation mechanism 13 in the lower separation zone is activated. Its first adsorption assembly 131 and second adsorption assembly 132 will classify and separate different types of antibacterial system waste by utilizing the differences in physical properties, such as electrical properties. Taking the second adsorption assembly 132 as an example, the second air pump 1325, fixed on the outer surface of the treatment chamber 5, delivers gas to the spiral tube 1321 that penetrates the treatment chamber 5 through the air duct 1326. The gas is discharged from the vent holes 1322 on the surface of the spiral tube 1321. At the same time, the spiral tube 1321 carries a specific charge. With the cooperation of the separator cover 1323 on the outer surface of the spiral tube 1321, the membrane fragments with corresponding electrical properties will be adsorbed onto the outer surface of the separator cover 1323. The first adsorption component 131 adsorbs the corresponding type of broken film using a similar principle, thereby achieving precise classification and separation of different types of antibacterial film waste. Through this series of continuous processing steps, the device effectively avoids the problems caused by mixing different antibacterial systems, realizes the effective recycling and classification of antibacterial PE preservation film waste, and improves recycling efficiency and equipment operational stability.

[0060] like Figures 1 to 9As shown, the storage mechanism 7 also includes a conical cover 71 fixedly connected to the outer surface of the storage cylinder 72. A funnel cylinder 73 is fixedly connected to the top of the storage cylinder 72, and a top plate 74 is fixedly connected to the top of the funnel cylinder 73. A symmetrical slot is provided at the connection between the storage cylinder 72 and the funnel cylinder 73. A sealing plate 75 is slidably connected inside the symmetrical slot. An electric telescopic rod 76 fixedly connected to the processing box 5 is provided on the outer side of the sealing plate 75. A cold air delivery pump 9 for supplying cold air is also provided on one side of the outer surface of the processing box 5.

[0061] like Figures 1 to 9 As shown, a sealing assembly 11 is provided at the bottom of the storage cylinder 72. The sealing assembly 11 includes a fourth servo motor 111 fixedly connected to the front of the outer surface of the processing box 5. The output end of the fourth servo motor 111 passes through the processing box 5 and is fixedly connected to a second rotating rod 112. A support rod 113 is fixedly connected to the outer circular surface of the second rotating rod 112. An arc-shaped cover 114 is fixedly connected to the top of the support rod 113. The blower assembly 12 includes an air guide duct 122 fixedly connected to the middle of the bottom of the processing box 5. A vent 121 is fixedly connected to the inside of the processing box 5 through the air guide duct 122. A motor 123 is fixedly connected to the middle of the inside of the air guide duct 122. A fan 124 is fixedly connected to the output end of the motor 123.

[0062] After the conveying mechanism 4 delivers the waste material into the upper processing area of ​​the processing box 5, the conical cover 71 on the outer surface of the storage cylinder 72 expands outward in a funnel shape, which can guide the fragments that may splash onto the inner wall of the processing box 5 during the crushing process back into the storage cylinder 72, avoiding waste residue and waste. The funnel cylinder 73 at the top of the storage cylinder 72 acts as a converging channel, concentrating the waste material delivered by the conveying mechanism 4 and guiding it to the working area of ​​the crushing mechanism 8, ensuring that the waste material can be accurately crushed; the top plate 74 at the top of the funnel cylinder 73 forms a barrier to prevent waste particles from splashing upward out of the processing area during crushing, maintaining an orderly environment in the upper processing area. Furthermore, during the crushing process of the crushing mechanism 8, the symmetrical slot at the connection between the storage cylinder 72 and the funnel cylinder 73 is in a closed state: the electric telescopic rod 76 pushes the sealing plate 75 to tightly embed into the slot, forming a temporary seal, ensuring that the crushed fragments remain temporarily in the funnel cylinder 73 until the crushing achieves the preset effect. Once the fragmented film size meets the pretreatment requirements, the electric telescopic rod 76 retracts, causing the sealing plate 75 to slide out of the slot. The slot opens, and the fragmented film falls smoothly into the storage cylinder 72 for temporary storage and pretreatment. At the same time, the cold air delivery pump 9 on the outer surface of the processing box 5 continuously monitors the temperature of the upper processing zone. Since the mechanical movement of the crushing mechanism 8 may generate heat, and high temperature can easily cause the antibacterial components (such as nano silver, quaternary ammonium salts, etc.) in the fragmented film to undergo chemical reactions, the cold air delivery pump 9 will deliver cold air to the upper processing zone in a timely manner to maintain the temperature within a suitable range, reduce the activity of antibacterial components from an environmental perspective, and create stable conditions for subsequent pretreatment. After the pretreatment of the fragmented membrane in the storage cylinder 72 is completed, the fourth servo motor 111 starts and drives the second rotating rod 112 to rotate slowly. The support rod 113 on the second rotating rod 112 then drives the arc-shaped cover 114 to rotate synchronously, so that the arc-shaped cover 114 fits tightly against the bottom of the storage cylinder 72. Then the sealing plate 75 is opened, so that the fragmented membrane is stored in the storage cylinder 72. The media supply module 10 on the outer surface of the processing box 5 supplies the processing media (such as warm water) into the storage cylinder 72 to briefly soak the fragmented membrane in warm water. Since the fragmented membrane is subjected to cold embrittlement treatment by liquid ammonia gas input by the cold air delivery pump 9 before being soaked in warm water, the impact of warm water on the fragmented membrane can induce the propagation of microcracks between different layers of the membrane, while reducing the chemical reactivity between different antibacterial system components, thereby reducing the formation of insoluble precipitates from the source. After the membrane fragments have been briefly soaked, the fourth servo motor 111 is restarted, causing the arc-shaped cover 114 to rotate 90 degrees, exposing the bottom opening of the storage cylinder 72. This allows the pre-treated membrane fragments to fall into the lower separation zone of the processing chamber 5 by gravity. If the pre-treatment is not yet complete, the arc-shaped cover 114 remains closed, forming a seal by tightly fitting the bottom of the storage cylinder 72. This prevents the membrane fragments from entering the lower separation zone prematurely and affecting the pre-treatment effect, and also prevents airflow from the lower separation zone from flowing back into the upper processing zone and interfering with the pre-treatment environment.

[0063] Once the membrane fragments enter the lower separation zone, the blower assembly 12 immediately starts to prepare for subsequent classification and separation. The air duct 122, fixed in the middle of the bottom of the processing box 5, acts as an airflow generator. The motor 123 inside drives the fan 124 to rotate at high speed, and the generated airflow flows upward. When it passes through the vent 121 at the top of the air duct 122, the porous structure of the vent 121 disperses the airflow into a uniform airflow field, covering the entire lower separation zone. This airflow can completely blow away the membrane fragments falling from the storage cylinder 72, so that the membrane fragments that might have been piled up are lifted up and suspended in the space. Each membrane fragment particle can be fully exposed and work in conjunction with the first adsorption assembly 131 and the second adsorption assembly 132 in the separation mechanism 13. They are used synchronously. The coiled tubes 1321 inside the first adsorption assembly 131 and the second adsorption assembly 132 carry specific charges to effectively distinguish and separate different types of antibacterial waste.

[0064] During the above operation, the storage mechanism 7 guides and temporarily stores the waste in an orderly manner, the cold air delivery pump 9 stabilizes the environment, the sealing component 11 precisely switches the processing stages, and the blower component 12 fully disperses the broken membrane. The entire device achieves a smooth transition from waste crushing to classification and separation, laying a solid foundation for the subsequent efficient recycling of waste from different antibacterial systems.

[0065] like Figures 1 to 9 As shown, recycling mechanisms 14 for collecting different types of antibacterial waste are provided on both sides of the bottom of the processing box 5. The recycling mechanism 14 includes an L-shaped plate 141 fixedly connected to both sides of the bottom of the processing box 5. A first hydraulic rod 142 is fixedly connected to the upper surface of the inner side of the L-shaped plate 141. A support plate 143 is fixedly connected to the top of the first hydraulic rod 142. A receiving pipe 144 is fixedly connected to one side of the support plate 143. A discharge port adapted to the outer diameter of the receiving pipe 144 is opened on both sides of the bottom of the processing box 5. An extension pipe 145 is fixedly connected to the bottom of the outer circular surface of the receiving pipe 144. A blocking plate 147 is provided at the top of the receiving pipe 144. A second hydraulic rod 146 fixedly connected to the receiving pipe 144 is provided at the middle of the bottom of the blocking plate 147.

[0066] After the first adsorption component 131 and the second adsorption component 132 of the separation mechanism 13 adsorb different types of antibacterial film fragments onto the outer surface of the corresponding separator 1323, the recycling mechanism 14 starts. The L-shaped plates 141 on both sides provide stable support for the entire recycling mechanism 14. The first hydraulic rod 142, fixed to the inner upper surface of the L-shaped plate 141, is activated first, pushing the top support plate 143 to move upward. The support plate 143 drives the receiving pipe 144 on one side to rise synchronously until the receiving pipe 144 covers the outer surface of the partition cover 1323 and forms a closure with the top cover 1324. Then, by starting the second air pump 1325, the swirling pipe 1321 outputs gas from the vent 1322, thereby using the airflow to blow off the film fragments adsorbed on the outer surface of the partition cover 1323. At this time, the second hydraulic rod 146 is used to contract it, so that the blocking plate 147 descends synchronously, thereby opening the discharge ports on both sides of the bottom of the processing box 5. Then, the film fragments adsorbed on the outer surface of the partition cover 1323 enter the receiving pipe 144 through the discharge port under the action of gravity or a slight airflow, and are then discharged through the extension pipe 145 at the bottom of the receiving pipe 144, and finally collected in the corresponding external container. After collection is complete, the second hydraulic rod 146 extends, pushing the blocking plate 147 to reset and seal the receiving pipe 144. The first hydraulic rod 142 retracts, causing the receiving pipe 144 to separate from the discharge port, awaiting the next recycling operation. Through the coordinated action of the first hydraulic rod 142 and the second hydraulic rod 146, the recycling mechanism 14 achieves precise and orderly collection of different types of antibacterial waste, ensuring that the sorted waste will not be mixed again, providing pure raw materials for subsequent recycling.

[0067] like Figures 1 to 9 As shown, the crushing mechanism 8 includes side plates 81 fixedly connected to both sides of the outer surface of the funnel cylinder 73. A first drive rod 82 and a second drive rod 83 are rotatably connected inside the funnel cylinder 73. The first drive rod 82 and the second drive rod 83 both pass through the side plates 81 and are respectively fixedly connected to a first gear 86 and a second gear 87. One end of the first drive rod 82 is provided with a third servo motor 85 fixedly connected to the side plate 81. Shearing components 84 are provided on the outer circular surfaces of the first drive rod 82 and the second drive rod 83. The shearing components 84 include a threaded sleeve 841 fixedly connected to the outer circular surface of the second drive rod 83. A crushing roller 843 fixedly connected to the second drive rod 83 is provided on the outer circular surface of the threaded sleeve 841. A cooling pipe 842 threadedly connected to the threaded sleeve 841 is provided on the inner side of the crushing roller 843.

[0068] The side plates 81 on both sides of the outer surface of the funnel cylinder 73 provide stable support for the entire crushing mechanism 8, and precisely position the first drive rod 82 and the second drive rod 83 inside the funnel cylinder 73. When the waste material enters the funnel cylinder 73 through the conveying mechanism 4, the third servo motor 85 starts, and its output end drives the first drive rod 82 to rotate. The first gear 86 at the end of the first drive rod 82 rotates accordingly. Through the meshing transmission with the second gear 87 on the second drive rod 83, the second drive rod 83 is driven to rotate synchronously. The rotation directions of the two drive rods are opposite. This reverse rotation drives the shearing components 84 on the outer circular surface of the two drive rods to cooperate with each other: the threaded sleeve 841 on the outer circular surface of the second drive rod 83 fixes the crushing roller 843 in the corresponding position. The shearing components 84 on the first drive rod 82 move synchronously with the same structure, so that the two sets of crushing rollers 843 form a relative rotational shearing relationship. When the waste material passes between the two sets of crushing rollers 843, it is quickly sheared into fine fragments to meet the size requirements of subsequent pretreatment and separation. At the same time, the cooling pipes 842 inside the crushing rollers 843 are fixed by threaded connection with the threaded sleeves 841, and cooling media (such as cold water or cold air) can be introduced to absorb the heat generated by mechanical friction during the crushing process. This prevents the antibacterial components from becoming more active due to high temperature in the fragments. Combined with the low temperature environment inside the treatment box 5, this further ensures the chemical stability of the crushed waste material.

[0069] like Figures 1 to 9 As shown, the conveying mechanism 4 includes a flow pipe 44 located at the bottom of the take-up roller 2, and square slots are provided on both sides of the upper surface of the flow pipe 44; a double-headed conveying pump 41 fixedly connected to the frame 1 is provided on one side of the flow pipe 44, one end of the double-headed conveying pump 41 is provided with a connecting pipe 42 communicating with the flow pipe 44, and the other end of the double-headed conveying pump 41 is provided with a conveying pipe 43 communicating with the funnel cylinder 73.

[0070] like Figures 1 to 9 As shown, the conveying mechanism 4 also includes a control module, which is configured with:

[0071] The waste conveying control unit is used to receive real-time monitoring signals of the waste accumulation status at the inlet of the flow pipe 44. When it is determined that the waste accumulation status has reached the preset control conditions, it sends a rate adjustment command to the dual-head conveying pump 41 to match the flow rhythm of the waste entering the flow pipe 44.

[0072] The temperature and humidity control unit is used to receive temperature and humidity detection signals in the processing box 5. When the temperature is detected to be outside the crushing processing range, it sends a cooling start signal to the cold air delivery pump 9 to maintain the low temperature environment of the processing box 5. When the humidity is detected to be below the interlayer separation range, it sends an intermittent warm water supply signal to the media supply module 10 to drive the phased delivery of warm water into the storage cylinder 72.

[0073] The adsorption intensity dynamic adjustment unit is used to receive the wind speed detection signal from the blower assembly 12, generate adsorption intensity adjustment parameters based on the wind speed change characteristics, and send the parameters to the first adsorption assembly 131 and the second adsorption assembly 132 respectively, so as to realize the adaptive control of electrostatic adsorption intensity and wind speed change.

[0074] like Figures 1 to 9 As shown, the processing box 5 is equipped with a temperature and humidity detection component, which includes:

[0075] The signal acquisition module is used to acquire real-time temperature data of the upper processing area through the temperature sensor integrated in the processing box 5, and at the same time acquire humidity data around the storage cylinder 72 through the humidity sensor, generating a multi-source monitoring signal that integrates the crushing environment temperature and the interlayer separation humidity conditions.

[0076] The intelligent analysis module is used to receive multi-source monitoring signals, and through logical analysis, it analyzes the deviation between temperature data and the crushing processing adaptation range, and the difference between humidity data and the interlayer separation adaptation range, and outputs a status judgment result including temperature over-limit indicator and humidity under-limit level.

[0077] The execution control module is used to perform response operations based on the status determination result.

[0078] like Figures 1 to 9 As shown, the execution control module is used to perform response operations based on the status judgment result, specifically including: when a temperature over-limit indicator is received, a cooling start signal is sent to the cold air delivery pump 9 to control the cold air delivery pump 9 to deliver cold air into the processing box 5 until the temperature data fed back by the temperature sensor falls back to the crushing processing adaptation range.

[0079] When a humidity level of insufficient is received, an intermittent warm water supply signal is sent to the media supply module 10. By adjusting the valve opening and closing frequency and duration of the media supply module 10, warm water is delivered to the storage cylinder 72 in stages until the humidity data fed back by the humidity sensor reaches the interlayer separation adaptation range.

[0080] When the temperature and humidity are both within their respective suitable ranges, a standby signal is sent to the cold air delivery pump 9 and the medium supply module 10.

[0081] The closed-loop verification module is used to continuously receive real-time data from the temperature and humidity detection component, dynamically adjust the cooling capacity parameters of the cold air delivery pump 9 and the warm water supply parameters of the medium supply module 10 according to the data changes, and send the adjusted parameters back to the execution control module to maintain the stability of the environment inside the processing box 5.

[0082] At the physical conveying level, the flow pipe 44 serves as the initial receiving structure for waste materials, with its bottom directly facing the take-up roller 2, ensuring that the corner waste generated during production can fall naturally under gravity. The square slots on both sides above it expand the receiving range, allowing waste materials to smoothly enter the pipe even if there are slight deviations in their landing position, preventing accumulation on the surface of the frame 1 and avoiding waste or cleaning burdens. The interior of the flow pipe 44 remains unobstructed, and its diameter is designed according to common waste material sizes, preventing blockages while forming a relatively concentrated conveying channel. The dual-head conveying pump 41, serving as the power source, is connected to the middle section of the flow pipe 44 via the connecting pipe 42. After starting, it creates a stable negative pressure inside the pipe, continuously drawing in waste materials. After pressurization, the waste is pushed through the conveying pipe 43 to the funnel cylinder 73 of the processing box 5, providing raw materials for subsequent crushing processing.

[0083] To ensure stable conveying, the control module achieves precise regulation through multi-unit collaboration. Detection components (such as infrared sensors or contact triggers) at the inlet of the flow pipe 44 sense the waste accumulation status in real time: when the waste accumulation thickness at the inlet exceeds a preset value, it is determined to be "oversupply," and the waste conveying control unit sends a speed-reducing command to the dual-head conveying pump 41 to reduce the conveying volume per unit time to avoid congestion; if there is no waste accumulation at the inlet for a long time, it is determined to be "undersupply," and a speed-increasing command is sent to ensure that the crushing mechanism 8 continuously obtains raw materials, avoiding idling and wasting energy.

[0084] Once the waste material enters the processing tank 5, the temperature and humidity control unit intervenes to regulate the environment. Since the mechanical shearing of the crushing mechanism 8 generates heat, if the temperature exceeds the suitable range set based on the stability of the antibacterial components (e.g., to prevent high-temperature oxidation of nano-silver), the temperature and humidity control unit immediately activates the cold air delivery pump 9, which delivers cold air to the upper processing area through pipes. The cold air is sprayed from multiple dispersed outlets, mixing with the air and cooling evenly to avoid localized sudden cooling that could alter the physical properties of the fragmented membrane. Regarding humidity control around the storage tank 72, appropriate humidity is required during the pretreatment stage to promote interlayer separation of the fragmented membrane. If the humidity sensor detects that the air is too dry (below the interlayer separation critical value), the unit sends a signal to the media supply module 10 to control the valve to periodically open and close. Each time the valve is opened, a measured amount of warm water is injected into the storage tank 72. The warm water contacts the fragmented membrane in the form of a mist or a fine stream, preventing the loss of antibacterial components due to excessive water and maintaining a stable humidity environment through intermittent supply, thus enhancing the microcrack propagation effect.

[0085] The adsorption intensity dynamic adjustment unit ensures the accuracy of the separation stage. Specifically, the wind speed of the blower assembly 12 changes due to factors such as the amount of broken film and the speed fluctuation of the fan 124: when the wind speed increases, the suspension height and movement speed of the broken film increase, and the unit increases the electrostatic adsorption intensity of the first adsorption assembly 131 and the second adsorption assembly 132 to enhance the capture force; when the wind speed decreases, the suspension height of the broken film decreases, and the unit reduces the adsorption intensity to avoid over-adsorption or mismatch. The separation accuracy is ensured through the dynamic balance of "wind speed - adsorption force".

[0086] The temperature and humidity detection component, acting as the "sensing center" of the control module, achieves accurate acquisition and processing of environmental data through the collaboration of three modules. The signal acquisition module employs a distributed sensing design. Temperature sensors are not only located near the crushing mechanism 8, but also have multiple measuring points at different locations in the upper processing area, using the average value as real-time temperature data to avoid single-point errors. Humidity sensors are evenly distributed around the outer wall of the storage cylinder 72, focusing on monitoring the core pre-processing area to ensure the data accurately reflects the humidity level of the membrane crushing environment. This data is integrated into a multi-source monitoring signal containing temperature, humidity values, and rates of change. The intelligent analysis module performs logical judgments based on preset adaptation range thresholds: when the temperature exceeds the upper limit, a "temperature exceeded" flag is generated; when the humidity is below the lower limit, it is classified into "humidity deficiency levels" (mild, moderate, severe) based on the difference. The higher the level, the greater the frequency and amount of subsequent warm water supply. Simultaneously, combined with data trend prediction, early warning signals are generated in advance. The execution control module operates with clear objectives and termination conditions: For excessive temperature, it sends a signal containing cooling intensity parameters to the cold air delivery pump 9, gradually reducing the speed when the temperature drops to the midpoint of the suitable range; for insufficient humidity, it sends a signal containing valve opening / closing intervals and durations to the media supply module 10 until the humidity reaches the ideal value; when the temperature and humidity are suitable, it sends a standby signal to keep the relevant equipment in a low-power state. The closed-loop verification module continuously tracks temperature and humidity changes. If the temperature drops too slowly after cold air delivery, it increases the cooling intensity; if the humidity rises too quickly after warm water supply, it reduces the single water supply volume, ensuring that the temperature and humidity remain stable within the optimal range through dynamic calibration. Through physical structure optimization and precise intelligent control, the conveying mechanism 4 not only achieves waste material transport without stagnation but also creates suitable conditions for subsequent crushing, pretreatment, and separation stages through dynamic environmental parameter balancing, ensuring the entire waste treatment process is efficient, stable, and controllable.

[0087] like Figures 1 to 9As shown, a guide mechanism 3 for guiding waste is provided directly above the take-up roller 2. The guide mechanism 3 includes a second servo motor 37 fixedly connected to one side of the outer surface of the frame 1. The output shaft of the second servo motor 37 is fixedly connected to a turntable 38. A connecting plate 39 is fixedly connected to the top of the turntable 38. A limiting cylinder frame 31 is fixedly connected to the bottom of the connecting plate 39. A first servo motor 32 is fixedly connected to one side of the outer surface of the limiting cylinder frame 31. A first rotating rod 33 is fixedly connected to the output end of the first servo motor 32. The first rotating rod 33 passes through the limiting cylinder frame 31 and is fixedly connected to an adsorption cylinder 34. Several adsorption holes are opened at the bottom of the adsorption cylinder 34. A connecting box 35 is fixedly connected to the top of the adsorption cylinder 34. A first air pump 36 for providing suction to the adsorption cylinder 34 is provided on one side of the outer surface of the limiting cylinder frame 31.

[0088] During the waste cutting process of cling film, the first servo motor 32 on the outer surface of the limiting cylinder 31 drives the adsorption cylinder 34 to adjust its angle in the vertical direction. The first rotating rod 33 connected to its output end passes through the limiting cylinder 31 and is fixed to the adsorption cylinder 34. When the first servo motor 32 is started, the first rotating rod 33 drives the adsorption cylinder 34 to rotate around the axis of the rotating rod, thereby changing the tilt angle of the bottom of the adsorption cylinder 34 so that it better fits the trajectory of the falling waste and improves the adsorption efficiency. When the bottom of the adsorption cylinder 34 fits the waste film, the first air pump 36 is started. It is connected to the adsorption cylinder 34 through the connecting box 35. After starting, Waste material is adsorbed onto the outer surface of the adsorption cylinder 34. Then, by starting the second servo motor 37, its output shaft drives the turntable 38 to rotate. This, in turn, drives the bottom limiting cylinder 31 to rotate synchronously through the top connecting plate 39, thereby adjusting the horizontal position of the adsorption cylinder 34. This guides the adsorbed waste film to the bottom of the take-up roller 2. At this point, the second servo motor 37 and the first air pump 36 are stopped. The waste film, having lost its suction, falls into the square slot of the flow pipe 44 due to gravity, so that the waste material can be accurately and efficiently guided to the subsequent conveying mechanism 4, providing front-end support for the smooth operation of the entire waste treatment process.

[0089] In use, the present invention first activates the guiding mechanism 3, which is responsible for precisely guiding the waste material generated by the take-up roller 2 to the conveying mechanism 4. Specifically, the first servo motor 32 on the outer surface of the limiting cylinder 31 drives the first rotating rod 33 to rotate, adjusting the tilt angle of the adsorption cylinder 34 so that it better conforms to the trajectory of the waste material falling. Then, the first air pump 36 is activated, providing negative pressure to the adsorption cylinder 34 through the connecting box 35, and adsorbing the waste material through the adsorption holes at the bottom. Next, the second servo motor 37 drives the turntable 38 and the connecting plate 39 to rotate, causing the adsorption cylinder 34 to move horizontally to the bottom of the take-up roller 2. At this time, the first air pump 36 is turned off, and the waste material, having lost its suction, falls into the square slot of the flow pipe 44 due to gravity. Afterwards, the conveying mechanism 4 starts operating, stably conveying the waste to the processing box 5. The flow pipe 44 expands its receiving range through the square slot on its upper surface, ensuring that the waste enters the pipe smoothly. The dual-head conveying pump 41 sucks the waste in the flow pipe 44 through the connecting pipe 42, and then pushes it to the funnel cylinder 73 of the processing box 5 through the conveying pipe 43. During this process, the waste conveying control unit of the control module plays a role, dynamically adjusting the speed of the dual-head conveying pump 41 by detecting the waste accumulation status at the inlet of the flow pipe 44: when excessive waste accumulation is detected at the inlet, a deceleration command is sent to prevent blockage; when the raw material is insufficient, a speed-up command is sent to ensure the continuous supply of material to the subsequent crushing mechanism 8, ensuring that the conveying rhythm matches the crushing demand. After the waste enters the processing box 5, it is first processed by the crushing mechanism 8 in the funnel cylinder 73. The side plates 81 fixed on both sides of the outer surface of the funnel cylinder 73 provide stable support for the entire crushing mechanism 8. After the third servo motor 85 is started, it drives the first drive rod 82 to rotate. Through the meshing transmission of the first gear 86 and the second gear 87, it drives the second drive rod 83 to rotate in the opposite direction, so that the crushing rollers 843 on the outer circular surface of the two drive rods form a relative rotational shearing relationship. When the waste passes between the two sets of crushing rollers 843, it is quickly sheared into fine film to meet the needs of subsequent processing. At the same time, the cooling pipe 842 on the inner side of the crushing roller 843 is circulated with cooling medium. Together with the cold air delivered by the cold air delivery pump 9 on the outer surface of the processing box 5, they maintain the low temperature environment of the upper processing area and prevent the antibacterial components in the film from becoming more active due to high temperature. The crushed film is temporarily stored in the storage cylinder 72 of the storage mechanism 7, and the top plate 74 of the funnel cylinder 73 forms a barrier to prevent the film from splashing upwards during the crushing process. The conical cover 71 on the outer surface of the storage cylinder 72 expands outwards in a funnel shape, which can guide the film that splashes onto the inner wall of the processing box 5 back into the storage cylinder 72 to avoid waste residue. The symmetrical slot at the connection between the storage cylinder 72 and the funnel cylinder 73 is controlled by a sealing plate 75 driven by an electric telescopic rod 76. During the crushing process, the sealing plate 75 is tightly embedded in the slot to form a seal, ensuring that the film stays temporarily in the funnel cylinder 73 until the crushing reaches the standard. When the size of the film meets the requirements, the electric telescopic rod 76 retracts, causing the sealing plate 75 to slide out of the slot, and the film falls smoothly into the storage cylinder 72 for temporary storage and pre-treatment.Furthermore, during the pretreatment stage, warm water is intermittently supplied to the storage cylinder 72 via the media supply module 10 on the outer surface of the treatment chamber 5. The warm water impacts the broken membrane in the form of mist or fine stream, inducing the propagation of microcracks between different membrane layers and reducing the chemical reactivity between different antibacterial system components. During this process, the temperature and humidity co-control unit regulates the environment in real time through the temperature and humidity detection component inside the treatment chamber 5: if the temperature of the upper treatment zone exceeds the suitable range for the breaking process, a cooling start signal is immediately sent to the cold air delivery pump 9 to deliver cold air to maintain the low temperature; if the humidity around the storage cylinder 72 is lower than the suitable range for interlayer separation, a signal is sent to the media supply module 10 to increase the frequency and amount of warm water supply per cycle. The closed-loop verification module continuously tracks temperature and humidity changes and dynamically adjusts the cooling capacity and warm water supply parameters to ensure that the environment remains stable within a suitable range. After pretreatment, the sealing assembly 11 is activated, and the fourth servo motor 111 drives the second rotating rod 112 to rotate, causing the support rod 113 and the arc-shaped cover 114 to rotate synchronously, so that the arc-shaped cover 114 is removed from the bottom of the storage cylinder 72. The broken film falls into the lower separation zone of the processing box 5 by gravity. At this time, the blower assembly 12 starts to work, and the motor 123 inside the air guide duct 122 drives the fan 124 to rotate at high speed. The generated airflow is dispersed into a uniform airflow field by the top vent 121, which blows away and lifts the broken film that has fallen into the lower separation zone, so that the broken film is fully dispersed in space. Then, through the separation mechanism 13 in the lower separation zone, the different physical characteristics (such as electrical properties) of the waste materials of different antibacterial systems are used for classification and separation. Taking the second adsorption assembly 132 as an example, the second air pump 1325 fixed on the outer surface of the processing box 5 is connected to the second adsorption assembly 132. Gas is delivered into the swirl tube 1321 through the air duct 1326. The gas is discharged from the vent holes 1322 on the surface of the swirl tube 1321. At the same time, the swirl tube 1321 carries a specific charge. With the cooperation of the separator 1323 on its outer surface, it adsorbs the scattered film fragments with corresponding charged characteristics, causing them to adhere to the outer surface of the separator 1323. The first adsorption component 131 adsorbs another type of film fragments with charged characteristics in a similar way. The adsorption intensity dynamic adjustment unit receives the wind speed detection signal from the blower component 12 and generates adsorption intensity adjustment parameters according to the wind speed change characteristics: when the wind speed increases, the electrostatic adsorption intensity of the two adsorption components is increased to enhance the capture force; when the wind speed decreases, the adsorption intensity is reduced to avoid over-adsorption or mismatch. The separation accuracy is ensured through the dynamic balance of "wind speed - adsorption force".Finally, the recycling mechanism 14 collects the sorted film fragments. This involves activating the first hydraulic rod 142 to push the support plate 143 upwards, simultaneously raising the receiving pipe 144 until it is fitted onto the outer surface of the separator 1323. Then, the second hydraulic rod 146 retracts, causing the blocking plate 147 to descend and open the channel of the receiving pipe 144. At this time, the second air pump 1325 continues to deliver gas through the coiled pipe 1321, using the airflow to blow off the film fragments adsorbed on the outer surface of the separator 1323. Under the influence of gravity and airflow, the film fragments enter the receiving pipe 144 through the discharge port, and are then discharged through the extension pipe 145 at the bottom of the receiving pipe 144, collected in the corresponding external container. After collection, the second hydraulic rod 146 extends, pushing the blocking plate 147 to reset and seal the receiving pipe 144. The first hydraulic rod 142 retracts, separating the receiving pipe 144 from the discharge port, ready for the next recycling operation.

The intelligent analysis module is used to receive multi-source monitoring signals, and through logical analysis, it analyzes the deviation between temperature data and the crushing processing adaptation range, and the difference between humidity data and the interlayer separation adaptation range, and outputs a status judgment result including temperature over-limit indicator and humidity under-limit level. The execution control module is used to perform response operations based on the status determination result.

9. The waste treatment device for the preparation of antibacterial PE preservation film according to claim 8, characterized in that, The execution control module is used to perform response operations based on the status determination result, specifically including: When a temperature over-limit indicator is received, a cooling start signal is sent to the cold air delivery pump to control the cold air delivery pump to deliver cold air into the processing box until the temperature data fed back by the temperature sensor falls back to the crushing processing range. When a humidity level of insufficient is received, an intermittent warm water supply signal is sent to the media supply module. By adjusting the valve opening and closing frequency and duration of the media supply module, warm water is delivered to the storage cylinder in stages until the humidity data fed back by the humidity sensor reaches the interlayer separation adaptation range. When the temperature and humidity are both within their respective suitable ranges, a standby signal is sent to the cold air delivery pump and the media supply module. The closed-loop verification module continuously receives real-time data from the temperature and humidity detection components, dynamically adjusts the cooling capacity parameters of the cold air delivery pump and the warm water supply parameters of the media supply module based on data changes, and sends the adjusted parameters back to the execution control module to maintain the stability of the environment inside the processing chamber.
