Description

Technical Field

[0001] The invention relates to the technical field of environmental protection equipment, in particular to a dust removal device for biodegradable films. Background Art

[0002] The raw materials of biodegradable films can be roughly divided into petroleum-based biodegradable plastics and plant-based biodegradable plastics. The typical petroleum-based product is polyvinyl alcohol (PVA), while the typical plant-based product is polylactic acid (PLA). In addition, there are other biodegradable polymer materials such as polycaprolactone (PCL) and polyhydroxybutyrate (PHB). Biodegradable films are themselves a type of film made of biodegradable materials. They can be decomposed by microorganisms in the environment and eventually converted into water, carbon dioxide and other substances. This type of film is environmentally friendly and can significantly reduce environmental pollution and waste of resources. As an environmentally friendly material, it is widely used in agriculture, packaging, civil engineering and other fields due to its naturally degradable properties.

[0003] In the prior art, such as Chinese patent number: CN106391583B, a biodegradable film dust removal device is provided, including a dust collector and a dust cleaner, a control panel is installed in front of the dust collector, a cleaning liquid storage bottle is installed on one side of the interior of the dust collector, a heating pipe is installed below the dust collector, a sewage pipe is installed at the bottom of the sewage storage tank, a fixing card is installed at the bottom of the dust outlet, the input end of the control panel is electrically connected to the output end of the motor, the heating pipe, the sprayer and the fan, and a reel is installed on the present invention, and a biodegradable film is installed on the reel. Driven by the motor, the reel rotates at a uniform speed, thereby driving the biodegradable film to rotate at a uniform speed. When the biodegradable film passes through the dust collector, the dust on the biodegradable film is cleaned by the dust removal function of the dust collector. This design avoids the problems of incomplete cleaning and inaccurate cleaning.

[0004] Although the above-mentioned equipment can use a vacuum cleaner to absorb and process the dust, the processing method is relatively simple and it is difficult to keep the dust completely processed, taking the use process as an example; During the production process, biodegradable films are often prone to adsorb dust and various impurities. This phenomenon not only significantly damages the appearance of the biodegradable film, but is also likely to have an adverse effect on its biodegradability and mechanical strength. The adhesion of dust and impurities may hinder the activity of microorganisms during the biodegradation process, thereby reducing its degradation efficiency. At the same time, these attachments also become stress concentration points, weakening the mechanical strength of the biodegradable film, thereby affecting its durability and reliability in practical applications. Therefore, taking effective measures to reduce dust and impurity adsorption during the production and winding process of biodegradable films is crucial to ensure their performance and quality. Summary of the invention

[0005] The purpose of the present invention is to provide a dust removal device for biodegradable film to solve the problem that the biodegradable film is often prone to adsorb dust and various impurities in its production process, which not only significantly damages the appearance of the biodegradable film, but also may have an adverse effect on its biodegradability and mechanical strength. The adhesion of dust and impurities may hinder the activity of microorganisms in the biodegradation process, thereby reducing its degradation efficiency.

[0006] To achieve the above object, the present invention provides the following technical solution: a dust removal device for biodegradable film, comprising: a retractable mechanism, a dust removal mechanism is fixedly installed on the top of the retractable mechanism, and a decomposition mechanism is fixedly installed on the top of the dust removal mechanism; The dust removal mechanism comprises a dust removal frame body, the bottom of which is fixedly provided with a group of second bottom anti-slip pads, the outer wall of the dust removal frame body is fixedly provided with two rectangular plates, one side of the outer wall of the two rectangular plates is fixedly provided with two groups of fixed limit plates, one side of the outer wall of the two rectangular plates is provided with a group of adjustment slots, one side of the outer wall of the two rectangular plates is fixedly provided with a group of fixed seats, the interiors of the two groups of fixed seats are threadedly connected with adjustment disks, one side of the outer wall of the two rectangular plates is fixedly provided with side plates, the interiors of the two side plates are rotatably connected with a first gear, the interiors of the two rectangular plates are fixedly provided with a first bearing seat, the interiors of the two first bearing seats are fixedly provided with a first driving rod, the outer wall of the first driving rod is fixedly provided with a first extrusion roller, one side of the outer wall of the first driving rod is fixedly provided with a second gear, the outer walls of the two groups of fixed limit plates are slidably embedded with a second bearing seat, the inner surface walls of the two groups of the second bearing seats are fixedly provided with a second driving rod, and the outer walls of the two second driving rods are fixedly provided with a second extrusion roller; Two insulating layers are fixedly connected inside the two second squeezing rollers; One side of the outer wall of two of the two groups of the second bearing seats is fixedly connected to an external conductive group, one side of the outer wall of the two second extrusion rollers is fixedly connected to a conductive ring, and the outer walls of the two groups of conductive rings are rotated inside the external conductive group; Two insulating pads are arranged inside the two groups of conductive rings. When the biodegradable film passes through the gap between the second squeezing roller and the first squeezing roller, it contacts the starting section of the positive terminal. At this time, the conductive ring equipped on the outer side of the positive terminal just rotates to the inside of the external conductive group, ensuring the transmission of electricity to the positive plate. Once the positive plate is charged, it will generate a strong electrostatic attraction with the attached charged dust particles (negative dust), and the dust particles on the surface of the biodegradable film will be tightly adsorbed on the electrode plate. As the biodegradable film continues to move backward, it is wrapped around the surface of the first squeezing roller. The first squeezing roller mainly plays a guiding role and does not have a dust adsorption function. At the same time, the circumference of the second squeezing roller is twice that of the first squeezing roller. When the biodegradable film is transferred from the first squeezing roller to the top second squeezing roller, , it just contacts with the negative end of the second squeezing roller. At this time, the conductive ring on the outside of the negative end also rotates to the inside of the external conductive group, and transmits electricity to the negative end of the second squeezing roller, thereby attracting and adsorbing the positive dust impurities carried on the other side of the biodegradable film to the negative end surface of the second squeezing roller. When the positive electrodes of the two second squeezing rollers contact the external conductive group, their negative electrodes enter a power-off state, causing the negative electrode of the electrode plate to lose charge, and the electrostatic attraction between the dust particles disappears. At this time, the negative electrode in the power-off state forms a rolling connection with the externally arranged rubber roller, and the viscosity of the rubber roller is used to effectively transfer the dust adsorbed by the negative electrode on the electrode plate to its surface. Similarly, when the positive electrode is in a power-off state, it is also treated in the same way to ensure that the dust on the outer wall of the two second squeezing rollers is effectively removed.

[0007] Preferably, a third gear is fixedly connected to one side of the outer wall of each of the two second driving rods, a chain is meshed and connected between the outer walls of the first gear, the second gear and the third gear, a fixed frame is fixedly connected to one side of the outer wall of the dust removal frame body, a movable groove is provided on the top of the fixed frame, a movable plate is embedded in the inner wall of the movable groove through a sliding block, firstly, an adjusting motor is installed on the top of the movable plate, and the bottom of the movable plate is cleverly slidably connected to the movable groove through the sliding block, so that the movable plate and the adjusting motor on the top of it can flexibly change their lateral position, thereby effectively adjusting the tightness of the chain.

[0008] Preferably, an adjusting motor is fixedly installed on the top of the movable plate, and the rotating end of the adjusting motor is meshed with the inside of the chain for transmission, a micro cylinder is fixedly installed on the top of the fixed frame, and the telescopic end of the micro cylinder is fixedly connected to one side of the outer wall of the movable plate, firstly, the adjusting motor is installed on the top of the movable plate, and the bottom of the movable plate is slidably embedded in the movable groove through a slider, thereby changing a lateral position relationship between the movable plate and the top adjusting motor, thereby adjusting the tightness of the chain.

[0009] Preferably, one side of the outer wall of the two rectangular plates is fixedly connected to an external frame plate, one side of the outer wall of the two external frame plates is fixedly connected to two groups of tooth grooves, one side of the outer wall of the dust removal frame body is slidably sleeved with two groups of sliding seats, one side of the outer wall of the two groups of sliding seats is fixedly connected to a driving motor, the rotating ends of the two groups of driving motors are fixedly connected to a transmission gear, and a rubber roller is rotatably connected between the opposite sides of the two groups of sliding seats. When the positive or negative electrodes included in the two second extrusion rollers are in an unpowered state, the unpowered end can be kept in contact with the outer wall of the rubber roller and generate a rolling friction state, and the impurities adsorbed when the power is off will be adhered to the rubber roller, thereby realizing the transfer of the impurities and improving the subsequent cleanliness of the outer wall of the second extrusion roller.

[0010] Preferably, the retractable mechanism comprises two biofilm support frames, a group of first bottom anti-skid pads are fixedly inserted at the bottom of the two biofilm support frames, a group of limit rods are fixedly connected to the top of the two biofilm support frames, a group of self-locking cylinders are fixedly inserted inside the two biofilm support frames, and a linkage U-shaped frame is fixedly installed between the telescopic ends of the two groups of self-locking cylinders. First, when the two retractable mechanisms complete the retractable treatment of the biodegradable film, the two groups of first bottom anti-skid pads at the bottom can contact the ground, thereby increasing the friction between the ground and the stability of the equipment, and when the two groups of self-locking cylinders use their own elasticity to push the two linkage U-shaped frames up and down to adjust their own height, when the self-locking cylinder moves to a certain set position, its internal hydraulic valve (or air pressure control valve) will control the inlet and outlet valves to close, at this time, the air pressure in the cylinder cavity is locked to form a relatively closed air pressure environment, due to the strong interaction between the molecules inside the gas, the gas in the cylinder is similar to the state of a solid in a closed state, thereby achieving self-locking and keeping the linkage U-shaped frame at an optimal height.

[0011] Preferably, a group of limit grooves are provided on the tops of the two linked U-shaped frames, and the outer walls of the two groups of limit rods are respectively slidably embedded in the limit grooves, and a group of semi-arc bearing grooves are provided inside the two linked U-shaped frames, and retractable rollers are engaged between the inner walls of the two groups of semi-arc bearing grooves. The two retractable rollers can be supported inside the semi-arc bearing grooves, and can effectively realize the self-rotation of the two retractable rollers to meet subsequent usage requirements.

[0012] Preferably, a first pulley is fixedly installed on one side of the outer wall of the two retracting rollers, and a transmission belt is transmission-connected inside the first pulley, an external motor is fixedly connected to the top of the linkage U-shaped frame, a second pulley is fixedly connected to the rotating end of the external motor, and the outer wall of the transmission belt is transmission-connected to the inside of the second pulley, and the outer wall of the two retracting rollers is wrapped with a biofilm body, and when the two external motors rotate at the same frequency, the biodegradable film is retracted and released on the inner walls of the two retracting rollers, so that the biodegradable film can pass through the decomposition mechanism and the dust removal mechanism one by one, so as to realize the dust treatment on the surface wall of the biodegradable film.

[0013] Preferably, the decomposition mechanism includes two L-shaped fixing plates, a plasma decomposer is fixedly installed between the tops of the two L-shaped fixing plates, and the tops of the two plasma decomposers are fixedly connected to positive and negative electrode detectors. When the biodegradable film passes through the internal space of the plasma decomposer, the equipment starts to operate and induces gas ionization based on the high-voltage electric field, thereby generating a large number of electrons and ions. Driven by the electric field force, the charged particles move toward the two poles and collide with the dust particles on the surface of the biodegradable film, so that the dust particles are also given an electric charge. At the same time, the two positive and negative electrode detectors monitor the entire decomposition process. The detector uses the suction force of the built-in fan to suck the air sample to be detected into it. Internally, the detector will convert the captured positive and negative ion signals into electrical signals. After this conversion process, the electrical signals will be amplified and filtered to further improve the clarity and stability of the signal. Then, the processed electrical signals will be converted into an intuitive representation of the positive and negative poles and stored in the internal memory of the detector for subsequent analysis. The detector also provides a data interface that allows the stored data to be transferred to an external computer for more in-depth data storage and analysis. When the detector detects that the concentration of positive and negative ions deviates from the preset threshold, it can respond quickly and automatically start and stop related devices to ensure that the positive and negative ion content inside the plasma decomposer can be stably maintained within the rated range.

[0014] Preferably, the bottoms of the two L-shaped fixed plates are fixedly connected to the top of the dust removal processing frame body, and the bottom of the dust removal processing frame body is fixedly connected to the tops of the two biofilm support frames. Firstly, with the mutual connection of the above-mentioned components, the connection between the retractable mechanism, the dust removal mechanism and the decomposition mechanism can be effectively realized, thereby improving the processing flow of the equipment.

[0015] Preferably, the circumference of the first squeezing roller is set to k, and the circumference of the two second squeezing rollers is 2k. The two second squeezing rollers are respectively composed of two semi-arc columns, and the two semi-arc columns are respectively the positive electrode plate and the negative electrode plate, and the positive electrode plate and the negative electrode plate can be electrically connected to the conductive ring. First, the circumference of the first squeezing roller is k. Based on this setting, the circumference of the two second squeezing rollers is designed to be 2k. The circumference of the positive electrode plate and the negative electrode plate inside the two second squeezing rollers is also precisely set to k. When the second squeezing roller at the bottom (equipped with the positive electrode plate) rotates one circle, the biodegradable film on its surface also moves. In this process, the biodegradable film will undergo a series of treatments, such as dust removal. , electrostatic adsorption, etc. When the second squeezing roller at the bottom completes one circle of rotation and transfers the biodegradable film to the first squeezing roller, the first squeezing roller will continue to guide the biodegradable film to move forward. After being transferred by the first squeezing roller, the biodegradable film can just reach the starting section of the second squeezing roller on the top, and at this time the section is just the negative electrode, ensuring that the biodegradable film can be treated with the positive electrode and the negative electrode respectively when passing through the two second squeezing rollers, thereby achieving effective removal of dust particles on the surface of the biodegradable film and electrostatic adsorption, ensuring the stability and continuity of the biodegradable film during the treatment process, and by optimizing the circumference and matching methods of each component, the equipment can achieve efficient and accurate biodegradable film treatment.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, firstly, when the equipment is in use, when the biodegradable film contacts the negative electrode of the second extrusion roller at the top, the negative end conductive ring also rotates in the external conductive group to realize power circulation, and transmits power to the negative end of the second extrusion roller, thereby adsorbing the positive electrode dust impurities carried on one side of the biodegradable film. When the positive electrodes of the two second extrusion rollers contact the external conductive group, the negative electrode is powered off, the electrode plate loses its charge, and the electrostatic attraction between the dust particles disappears. At this time, the negative electrode in the power-off state is in rolling contact with the externally arranged rubber roller, and the dust on the electrode plate is adsorbed between the outer walls of the rubber roller by utilizing the viscosity of the rubber roller, which not only ensures the cleanliness of the equipment, but also extends its service life. Through the advantages of high efficiency and stable operating performance, it provides an efficient and reliable dust removal method for the treatment of biodegradable films.

[0017] 2. In the present invention, the equipment can be precisely adjusted according to the thickness of the biodegradable film. By rotating the adjustment disk, the distance between the two second extrusion rollers and the first extrusion roller can be conveniently adjusted to meet the use requirements of biodegradable films of different thicknesses. The transmission system realizes effective power transmission through the cooperation of the first gear, the second gear and the two second gears. At the same time, the micro cylinder as a driving force can push the moving plate and the top adjustment motor to move to one side, thereby adjusting the length of the chain to adapt to the change in the position between the gears. This flexible transmission system not only improves the operating efficiency of the equipment, but also enhances its ability to adapt to different working environments.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the implementation rules described 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 creative work are within the scope of protection of the present invention. Embodiment 1, refer to Figure 1 - Fig.12 As shown: The present invention provides a dust removal device for biodegradable film, comprising: a retractable mechanism 1, a dust removal mechanism 2 is fixedly installed on the top of the retractable mechanism 1, and a decomposition mechanism 3 is fixedly installed on the top of the dust removal mechanism 2; The dust removal mechanism 2 includes a dust removal processing frame body 21, a group of second bottom anti-slip pads 211 are fixedly inserted at the bottom of the dust removal processing frame body 21, two rectangular plates 22 are fixedly installed on the outer wall of the dust removal processing frame body 21, two groups of fixed limit plates 221 are fixedly installed on one side of the outer wall of the two rectangular plates 22, a group of adjustment grooves 222 are opened on one side of the outer wall of the two rectangular plates 22, a group of fixed seats 223 are fixedly installed on one side of the outer wall of the two rectangular plates 22, and the interiors of the two groups of fixed seats 223 are threadedly connected with adjustment disks 224, and side plates 225 are fixedly installed on one side of the outer wall of the two rectangular plates 22. 5 are rotatably connected with the first gear 226, the first bearing seats 23 are fixedly installed inside the two rectangular plates 22, the first driving rods 231 are fixedly inserted inside the two first bearing seats 23, the outer wall of the first driving rods 231 is fixedly sleeved with a first squeezing roller 232, and the outer wall of the first driving rods 231 is fixedly connected with a second gear 233, the outer walls of the two groups of fixed limiting plates 221 are slidably embedded with a second bearing seat 24, the inner walls of the two groups of second bearing seats 24 are fixedly inserted with a second driving rod 241, and the outer walls of the two second driving rods 241 are fixedly sleeved with a second squeezing roller 242; Two insulating layers 2421 are fixedly connected inside the two second squeezing rollers 242; One side of the outer wall of two of the two sets of second bearing seats 24 is fixedly connected to an external conductive group 243, one side of the outer wall of the two second squeezing rollers 242 is fixedly connected to a conductive ring 244, and the outer walls of the two sets of conductive rings 244 are rotated inside the external conductive group 243; Two insulating pads 2441 are disposed inside the two sets of conductive rings 244; A third gear 245 is fixedly connected to one side of the outer wall of the two second driving rods 241, and a chain 251 is meshed and connected between the outer walls of the first gear 226, the second gear 233 and the third gear 245. A fixed frame 26 is fixedly connected to one side of the outer wall of the dust removal frame body 21, and a moving groove 261 is opened on the top of the fixed frame 26. A moving plate 262 is slidably embedded in the inner wall of the moving groove 261 through a slider, and an adjusting motor 25 is fixedly installed on the top of the moving plate 262, and the rotating end of the adjusting motor 25 is meshed and driven with the inside of the chain 251. The top of the fixed frame 26 is fixedly installed A micro cylinder 263 is installed, and the telescopic end of the micro cylinder 263 is fixedly connected to one side of the outer wall of the moving plate 262, one side of the outer wall of the two rectangular plates 22 is fixedly connected to the external frame plate 27, one side of the outer wall of the two external frame plates 27 is fixedly connected to two groups of tooth grooves 271, one side of the outer wall of the dust removal frame body 21 is slidably sleeved with two groups of sliding seats 28, one side of the outer wall of the two groups of sliding seats 28 is fixedly connected to a driving motor 281, the rotating ends of the two groups of driving motors 281 are fixedly connected to a transmission gear 282, and a rubber roller 283 is rotatably connected between the opposite sides of the two groups of sliding seats 28; The circumference of the first squeezing roller 232 is set to k, and the circumference of the two second squeezing rollers 242 is 2k. The two second squeezing rollers 242 are respectively composed of two semi-arc-shaped columns, and the two semi-arc-shaped columns are respectively the positive electrode plate and the negative electrode plate, and the positive electrode plate and the negative electrode plate can be electrically connected to the conductive ring 244 respectively; The decomposition mechanism 3 includes two L-shaped fixing plates 31, a plasma decomposer 32 is fixedly installed between the tops of the two L-shaped fixing plates 31, the tops of the two plasma decomposers 32 are fixedly connected to positive and negative pole detectors 33, and the bottoms of the two L-shaped fixing plates 31 are fixedly connected to the top of the dust removal processing frame body 21.

[0021] In this embodiment, when the biodegradable film first passes through the interior of the plasma decomposer 32, the plasma decomposer 32 itself starts to operate, ionizing the gas based on the high voltage electric field to generate a large number of electrons and ions. These electrons and ions move toward the two poles under the action of the electric field force, and collide with the dust particles on the surface of the biodegradable film during the movement, causing them to be charged; And in the process of decomposition, the two positive and negative electrode detectors 33 set externally can effectively monitor this decomposition, and the air to be tested is sucked into the instrument through the built-in fan of the instrument, and then the collected air sample is subjected to necessary pretreatment (such as filtration, dehumidification, etc.), and the detected positive and negative ion signals are converted into electrical signals, and amplified and filtered, and the processed electrical signals are converted into the form of positive and negative electrode representation, and the processed data are recorded in the internal memory of the instrument, or transmitted to an external computer through a data interface for storage and analysis. When the positive and negative ion concentrations are monitored to exceed or fall below the preset threshold, the instrument should be able to automatically start and stop the device, so as to keep the internal positive and negative ion content at the rated value; When the biodegradable film first passes between the bottom second squeezing roller 242 and the first squeezing roller 232, after the biodegradable film contacts the starting section of the positive terminal, the conductive ring 244 arranged on one side of the outer wall of the positive terminal just rotates inside the external conductive group 243, thereby realizing the flow of electricity and transferring electricity to the positive plate. When the positive plate is charged, it will generate electrostatic attraction between it and the charged dust particles. This attraction can firmly adsorb the dust particles (negative electrode dust) on the surface of the biodegradable film on the electrode plate, and then continue to rotate backward. When the biodegradable film is wrapped around the surface wall of the first squeezing roller 232, due to the guiding effect of the first squeezing roller 232 itself, it does not have the dust adsorption effect, and the circumference of the second squeezing roller 242 is twice that of the first squeezing roller 232. When it is wrapped around the outer wall of the first squeezing roller 232 and contacts the top of the two second squeezing rollers 242, it just contacts the negative electrode of the top second squeezing roller 242. Similarly, during the rotation process, the conductive ring 244 arranged on the outer wall side of the negative end also happens to rotate inside the external conductive group 243, thereby transmitting electricity to the negative end of the top second squeezing roller 242, so that the impurities carrying positive electrode dust on one side of the biodegradable film can be adsorbed on the negative end surface wall of the second squeezing roller 242, and when the positive electrodes of the two second squeezing rollers 242 are in contact with the external conductive group 243, the negative electrodes of the two second squeezing rollers 242 are in a power-off state, and the negative electrode of the electrode plate loses its charge, so the electrostatic attraction between it and the dust particles will disappear, and at this time, the negative electrode in the power-off state can be in rolling connection with the externally arranged rubber roller 283, so that the dust adsorbed by the negative electrode on the electrode plate can be effectively adsorbed between the outer walls of the rubber roller 283. Similarly, when the positive electrode is in a power-off state, it can also be processed in the same way. By utilizing the viscosity of the rubber roller 283, the dust on the outer walls of the two second squeezing rollers 242 can be processed.

[0023] In this embodiment, firstly, the two groups of adjusting disks 224 are rotated respectively.

[0024] Embodiment 3, according to Figure 1-Figure 11 As shown, the retracting and releasing mechanism 1 includes two biofilm support frames 11, a group of first bottom anti-slip pads 111 are fixedly inserted at the bottom of the two biofilm support frames 11, a group of limiting rods 112 are fixedly connected to the tops of the two biofilm support frames 11, a group of self-locking cylinders 12 are fixedly inserted inside the two biofilm support frames 11, a linkage U-shaped frame 13 is fixedly installed between the telescopic ends of the two groups of self-locking cylinders 12, a group of limiting grooves 131 are opened on the tops of the two linkage U-shaped frames 13, and the outer walls of the two groups of limiting rods 112 are respectively slidably embedded in the limiting grooves 131, and the two linkages A group of semi-arc bearing grooves 132 are arranged inside the movable U-shaped frame 13, and a retracting roller 14 is clamped between the inner surface walls of the two groups of semi-arc bearing grooves 132. A first pulley 141 is fixedly installed on one side of the outer wall of the two retracting rollers 14, and a transmission belt 142 is connected to the inside of the first pulley 141. The top of the linkage U-shaped frame 13 is fixedly connected to an external motor 15, and the rotating end of the external motor 15 is fixedly connected to the second pulley 143, and the outer surface wall of the transmission belt 142 is connected to the inside of the second pulley 143, and the outer surface wall of the two retracting rollers 14 is wrapped with a biofilm body 16; The decomposition mechanism 3 includes two L-shaped fixing plates 31 , a plasma decomposer 32 is fixedly installed between the tops of the two L-shaped fixing plates 31 , and the tops of the two plasma decomposers 32 are both fixedly connected with positive and negative electrode detectors 33 .

[0025] In this embodiment, when the dust removal mechanism 2 meets the use requirements of different biodegradable film thicknesses, the retractable mechanism 1 also needs to be adjusted according to the adjustment of the dust removal mechanism 2. First, two groups of identical retractable mechanisms 1, each group of self-locking cylinders 12, when powered on, start to rotate at their output ends, which can push the two linked U-shaped frames 13 to move up and down respectively. In this process, the two linked U-shaped frames 13 are slidably limited in the two groups of limit rods 112 respectively to maintain stability during the sliding process. In this way, the two retractable rollers 14 can be adjusted to be at different heights. In the process of the two external motors 15 rotating at the same frequency, the biodegradable film is retracted and released on the inner walls of the two retractable rollers 14, which can ensure that the biodegradable film can pass through the decomposition mechanism 3 and the dust removal mechanism 2 one after another, so as to achieve dust treatment on the surface wall of the biodegradable film.

[0026] The working principle of the entire mechanism is as follows: when the equipment is in use, it needs to be adjusted accordingly according to the thickness of the biodegradable film. First, by rotating the two sets of adjusting disks 224, threaded rotation is generated inside the fixed seat 223. This rotating connection also allows the bottom of the adjusting disk 224 to rotate in the second bearing seat 24. With the sliding embedding of the second bearing seat 24 in the fixed limiting plate 221, the distance between the two second extrusion rollers 242 and the first extrusion roller 232 can be adjusted. This spacing adjustment can meet the use requirements of biodegradable films of different thicknesses. In this process, the adjustment of the two second bearing seats 24 will cause the distance between the first gear 226, the second gear 233 and the two third gears 245 to change. At this time, the micro cylinder 263 acts as a driving force to slide and embed the slider in the movable groove 261. Under the cooperation, the movable plate 262 and the top adjustment motor 25 are pushed to move to one side, so as to adjust the length of the chain 251 to adapt to the position change between the first gear 226, the second gear 233 and the two third gears 245. When the dust removal mechanism 2 meets the use requirements of biodegradable films of different thicknesses, the retracting mechanism 1 also needs to be adjusted accordingly. In the two sets of identical retracting mechanisms 1, the two sets of self-locking cylinders 12 are elastic when powered on, pushing the linkage U-shaped frame 13 to move up and down. At the same time, the linkage U-shaped frame 13 slides on the limit rod 112 to maintain stability, and the different height positions of the two retracting rollers 14 can be adjusted. When the two external motors 15 rotate at the same frequency, the biodegradable film is processed in the two retracting rollers 14 in a retracting and releasing manner, ensuring that the biodegradable film can continuously pass through the decomposition mechanism 3 and the dust removal mechanism 2 for the next step of processing; When the biodegradable film first passes through the plasma decomposer 32, the operation of the plasma decomposer 32 generates a large number of electrons and ions. These charged particles collide with the dust particles on the surface of the biodegradable film under the action of the electric field force and charge them. At the same time, the two positive and negative electrode detectors 33 set outside effectively monitor the decomposition process, record and analyze data through preprocessing, signal conversion, amplification, filtering and other steps. When the positive and negative ion concentrations are monitored to exceed or fall below the preset threshold, the instrument uses an automatic start-stop device to keep the internal positive and negative ion content stable. Subsequently, when the biodegradable film passes between the second squeezing roller 242 and the first squeezing roller 232 at the bottom, after contacting the positive electrode starting section, the conductive ring 244 rotates in the external conductive group 243 to realize power flow and transfer power to the positive plate. After the positive plate is charged, it generates electrostatic attraction with the charged dust particles, firmly adsorbing the dust particles on the electrode plate. As the biodegradable film continues to rotate backward and entangle When winding around the surface wall of the first squeezing roller 232, due to the guiding effect of the first squeezing roller 232 and the lack of dust adsorption effect, the biodegradable film then contacts the negative electrode of the top second squeezing roller 242. Similarly, the negative end conductive ring 244 also rotates in the external conductive group 243 to realize power flow, and transmits power to the negative end of the second squeezing roller 242, thereby adsorbing the positive electrode dust impurities carried on one side of the biodegradable film. When the positive electrodes of the two second squeezing rollers 242 contact the external conductive group 243, the negative electrode is powered off, the electrode plate loses its charge, and the electrostatic attraction between the dust particles disappears. At this time, the negative electrode in the power-off state is in rolling connection with the externally arranged rubber roller 283, and the dust on the electrode plate is adsorbed between the outer walls of the rubber roller 283 by utilizing the viscosity of the rubber roller 283. Similarly, when the positive electrode is powered off, the dust can also be handled in the same way. By utilizing the viscosity of the rubber roller 283, the dust on the outer walls of the two second squeezing rollers 242 can be cleaned. In this treatment method, only one side of the biodegradable film is treated. After one side of the biodegradable film is treated, the biodegradable film is moved to the starting section, changed its position, and then the other side is treated in the same manner as above.
