Description

Technical Field

[0001] The present invention relates to the technical field of on-vehicle film recycling devices, and more specifically, to a waste recycling device for on-vehicle film production. Background Art

[0002] During the production of on-vehicle films, the finished films need to be wound into film rolls by a winding device, and then the film rolls are packaged and sold. However, after the winding is completed, due to certain errors in the operation of the winding device, the edges of the film rolls will appear uneven and ragged. These ragged edges will affect the sale of the film rolls. Therefore, the edges of the film rolls need to be trimmed. These trimmed ragged edges are film waste, and these wastes need to be recycled to save production costs. In the prior art, the patent document with the publication number CN220219300U discloses a gas separation membrane waste recycling device. The above device pre-cuts the waste through the cooperation of a circular knife and a cutting bottom roller, and roughly cuts the waste. Subsequently, the waste is completely pulverized through the cooperation of a first crushing roller and a second crushing roller, improving the crushing effect of the waste, facilitating the subsequent recycling of the waste, and improving the usability. However, the above device has the following technical problems when in use: The existing device lacks an efficient vibration dispersion mechanism, and the waste is prone to accumulate in the tank. The traditional device drives the cutter in a single direction, making it difficult to cope with the toughness and ductility of on-vehicle films, resulting in incomplete crushing. In the continuous shearing mode of the existing device, lightweight film waste is prone to entangle the cutter. The fixed cutter of the existing device can only provide a single-direction shearing force for ductile films, easily causing the waste to stretch and entangle, and the wear of the cutter edge is concentrated in a local area, with a short service life; Based on this, the present invention provides a waste recycling device for on-vehicle film production to solve the technical problems raised in the above background art.

[0012] As a preferred technical solution of the present invention, the heat supply component includes a wind cylinder installed on the tank body. The bottom end of the wind cylinder is communicated with the inner cavity of the tank body. A filter element and an electric heating fan are sequentially installed on the inner wall of the wind cylinder from top to bottom. A temperature probe for monitoring the temperature of the inner cavity of the tank body is installed on the tank body. A central control host is installed on the end face of the tank body.

[0013] As a preferred technical solution of the present invention, the number of the bevel gear surfaces and the toothless surfaces is the same, and the central angles corresponding to the bevel gear surfaces and the toothless surfaces are the same. The multiple bevel gear surfaces and the multiple toothless surfaces are arranged at intervals of two on the fixed tooth ring.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The prior art uses a single-direction drive for the cutter, which is difficult to effectively break the tough material of the vehicle-mounted film, resulting in incomplete breaking. The present invention drives the first incomplete gear and the second incomplete gear to alternately mesh with the differential gear through the eccentric shaft, uses the difference in gear radius and height difference to form a speed difference, forces the large circular shaft to store energy and reset through the second torsion spring, realizes the periodic forward and reverse rotation of the variable-direction shaft, the variable-direction shaft drives the positive cutter barrel and the reverse cutter barrel in the feeding cylinder to rotate coaxially and in opposite directions, the moving cutting edge on the cutter shaft reciprocates under the action of the bevel gear surface of the fixed tooth ring, forming an "impact shear" composite breaking effect. At the same time, the fixed cutting edge at the bottom of the reverse cutter barrel performs secondary breaking on the falling material. This two-way and variable-direction shearing mode can damage the fiber structure of the vehicle-mounted film from multiple angles, especially suitable for the delamination breaking of multi-layer composite films. Compared with the traditional single-direction shearing, the breaking efficiency is significantly improved, and the problem of film stretching and winding caused by single-direction cutting can be effectively avoided.

[0015] In the existing continuous shearing mode, lightweight film waste is prone to winding around the cutting tool, and the unidirectional shearing force of the fixed blade will cause the waste to stretch and wind, and the local wear of the cutting edge is serious. In the multi-tooth intermittent transmission system of the present invention, a power interruption area is set, so that the reversing shaft periodically enters a stage without power transmission during the driving process, providing relaxation time for the lightweight film wound around the tool assembly, avoiding fiber accumulation or tool jamming caused by continuous shearing. At the same time, the reciprocating displacement stroke of the longitudinal vibration frame is periodically adjustable. Through the linkage of the reciprocating lead screw and the reversing shaft, the reciprocating vibration stroke of the longitudinal vibration frame is alternately and cyclically changed. When vibrating with a large stroke, a stronger tearing force can be applied to the hard waste, and when vibrating with a small stroke, the film fiber can be quickly cut off by high-frequency and small-amplitude vibration. Moreover, the change of the vibration stroke makes the sieve holes of the spiral sieve blades form a dynamic opening and closing effect, shaking off the attached fine particles, significantly reducing the sieve hole blockage rate. Compared with the continuous transmission and fixed vibration mode of the traditional device, the present invention starts from two aspects of power transmission and vibration parameter adjustment, effectively solves the industry pain points of "knife winding" and "sieve blockage", reduces the equipment maintenance cost, and improves the recovery efficiency.

[0016] The prior art does not consider the material characteristics of vehicle-mounted film waste, which has a large crushing resistance and low processing efficiency. The present invention conveys hot air at 60°C - 120°C to the inner cavity through the heat supply component at the top of the tank body, and realizes precise temperature control by using the temperature probe and the central control host. The hot air penetrating the waste layer can reduce the intermolecular force of the polymer chain, making the film more brittle and easier to break. The resistance of the softened waste is significantly reduced when sheared by the tool assembly, and the broken particle size is more uniform. At the same time, the vertical vibration of the longitudinal vibration frame, the lifting and screening of the feeding cylinder, and the rotary crushing of the cutter group form multi-action coordination. For example, when processing waste containing adhesives, vibration can destroy the adhesive connection, and the synchronously rotating cutter group and sieve blades quickly complete crushing and screening, with the processing efficiency increased by more than 50% compared with the traditional step-by-step processing.

[0017] The present invention drives the eccentric shaft and the eccentric wheel through the servo motor in the multi-tooth intermittent transmission system, and cooperates with the rollers and the reset elastic element on the horizontal vibration table to realize the horizontal reciprocating vibration of the horizontal vibration table along the guide rail frame. This high-frequency vibration screening principle can quickly disperse and evenly heat the waste in the tank body. Compared with the waste accumulation problem caused by the lack of vibration dispersion in the prior art, the present invention can significantly improve the waste processing efficiency, avoid situations such as insufficient crushing and uneven heat softening caused by accumulation. At the same time, the elastic limit mechanism of the reset elastic element reduces the impact of vibration on the equipment and prolongs the service life of the device. Description of the Drawings

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1 to 11As shown, the present invention provides a waste material recovery device for vehicle-mounted film production, comprising a tank body 1, a multi-tooth intermittent transmission system installed on the top of the tank body 1, and a transverse vibration table 2 that can be moved back and forth in the horizontal direction and a direction-changing shaft 3 that can reciprocate forward and reverse within a set period are connected to the multi-tooth intermittent transmission system; A longitudinal vibration frame 4 is mounted on the transverse vibration table 2 and is driven by a direction-changing shaft 3 and can be moved back and forth in the vertical direction. The reciprocating movement stroke of the longitudinal vibration frame 4 is periodically adjustable. The multi-tooth intermittent transmission system includes a servo motor 17 mounted on the tank body 1, an eccentric shaft 18 rotatably connected to the tank body 1, and a bracket 19 fixedly mounted in the tank body 1. The output shaft end of the servo motor 17 is connected to the eccentric shaft 18 through a first synchronous belt. An eccentric wheel 20 is mounted on the bottom of the eccentric shaft 18. A roller 21 is rotatably mounted on the transverse vibration table 2. The outer contour of the eccentric wheel 20 is in rolling contact with the outer contour of the roller 21. A reset elastic element 22 limited by the tank body 1 is mounted on the side of the transverse vibration table 2. A guide rail frame slidably connected to the transverse vibration table 2 is fixedly mounted on the inner wall of the tank body 1. The servo motor 17 drives the eccentric shaft 18 and the eccentric wheel 20, which cooperate with the roller 21 and the reset elastic element 22 on the transverse vibration table 2 to achieve horizontal reciprocating vibration of the transverse vibration table 2 along the guide rail frame. This design effectively simulates the principle of high-frequency vibration screening, allowing the waste to be quickly dispersed and evenly heated in the tank body 1, avoiding the decrease in processing efficiency caused by waste accumulation. The elastic limit mechanism of the reset elastic element 22 reduces the impact of vibration on the structure of the tank body 1, extending the life of the equipment. At the same time, the sliding connection of the guide rail frame ensures the accuracy and stability of the movement of the transverse vibration table 2. By the reciprocating movement of the horizontal vibration table 2 in the horizontal direction, the movable blade 16 and the fixed blade 13 can be horizontally reciprocated at a set speed during the revolution. By the reciprocating movement of the blade during rotation, the synchronous rotary cutting and frictional cross-cutting of the vehicle-borne film waste can be achieved, thereby improving the efficiency and effect of the crushing of the vehicle-borne film waste. At the same time, by the horizontal reciprocating movement of the movable blade 16 and the fixed blade 13, the vehicle-borne film waste adhering to the blade or the vehicle-borne film waste wrapped around the blade can be vibrated and shaken off or horizontally cut off, thereby reducing the winding rate of the vehicle-borne film waste on the movable blade 16 and the fixed blade 13. The multi-tooth intermittent transmission system further includes a first incomplete gear 23 and a second incomplete gear 24 mounted on the eccentric shaft 18, and two symmetrically arranged power interruption areas are provided between the first incomplete gear 23 and the second incomplete gear 24; A large circular shaft 25, a small circular shaft 26, and a flower shaft 27 are rotatably mounted on the bracket 19. A second torsion spring 28 is fixedly mounted at the rotational connection between the large circular shaft 25 and the bracket 19. Two differential gears 29 are mounted on the large circular shaft 25. The two differential gears 29 are respectively adapted to be connected to the first incomplete gear 23 and the second incomplete gear 24. The first incomplete gear 23 and the second incomplete gear 24 are symmetrically arranged on the eccentric shaft 18. The first incomplete gear 23 and the second incomplete gear 24 have different heights in the vertical direction. The central angles corresponding to the first incomplete gear 23 and the second incomplete gear 24 are both 120°, and the central angles corresponding to the two power interruption areas are both 60°. The radii of the first incomplete gear 23 and the second incomplete gear 24 are different, and the radii of the two differential gears 29 are different.

[0022] The eccentric shaft 18 drives the first incomplete gear 23 and the second incomplete gear 24 to alternately mesh with the differential gear 29, and utilizes the gear radius difference and height difference to form a speed difference, forcing the large circular shaft 25 to reset through the second torsion spring 28 to store energy, thereby realizing the periodic forward and reverse rotation of the change shaft 3. This process provides a directional power for the recycling treatment of vehicle-borne film waste through the "intermittent meshing differential speed change" mechanism of gear transmission, breaking through the limitation of the unidirectional drive of the traditional device. When the vehicle-borne film waste needs to be crushed at multiple angles due to the toughness of the material, the forward and reverse rotation of the change shaft 3 can drive the spiral screen blades in the lifting barrel 5 to alternately change the rotation direction, so that the vehicle-borne film waste is subjected to bidirectional rubbing and screening during the lifting process, significantly improving the screening accuracy, and is particularly suitable for the layered crushing and screening needs of multi-layer composite film vehicle-borne film waste. At the same time, by periodically adjusting the rotation speed and rotation direction of the direction-changing shaft 3, on the one hand, the crushing efficiency and crushing strength of the movable blade 16 and the fixed blade 13 on the vehicle-borne film waste can be cyclically changed, and on the other hand, the crushing and cutting direction of the movable blade 16 and the fixed blade 13 on the vehicle-borne film waste can be cyclically changed, and finally an alternating direction-changing shearing and crushing effect of the vehicle-borne film waste can be achieved; The power interruption zone is formed by setting a symmetrical 60° central angle interruption zone between the first incomplete gear 23 and the second incomplete gear 24, so that the direction-changing shaft 3 periodically enters a no-power transmission stage during the driving process; This intermittent transmission mechanism provides relaxation time for the lightweight film wrapped around the tool assembly during waste crushing through the brief pause in the power interruption zone, thereby avoiding fiber accumulation or tool jamming caused by continuous shearing. It is particularly suitable for the characteristics of vehicle-mounted film waste that is easy to wrap. Combined with the radius difference of the differential gear 29, the power interruption zone causes the rotation direction of the change-direction shaft 3 to switch periodically, driving the positive knife cylinder 6 and the reverse knife cylinder 7 to rotate alternately in opposite directions, forming a dynamic change in shear force. This process can tear the waste into more uniform particles, reduce large pieces of residue, and at the same time disperse the equipment load and reduce gear wear. The brief vibration pause in the interruption stage is coordinated with the vertical stroke adjustment of the longitudinal vibration frame 4, so that the waste in the spiral screen blade 34 is fully dispersed in the screen hole 35, avoiding the blockage of the screen hole due to continuous vibration, and significantly improving the screening efficiency of fine particles.

[0023] Compared to traditional continuous transmission devices, this design solves the industry pain points of "blade entanglement" and "screen clogging" in vehicle-mounted film waste crushing through precise intermittent power distribution. While ensuring high recovery rates, it also reduces energy consumption and extends the life of key components, reflecting the deep integration of structural innovation and process adaptation. A second synchronous belt is connected between the large circular shaft 25 and the small circular shaft 26. A first bevel gear is installed on the small circular shaft 26 and the flower shaft 27. The two first bevel gears are engaged with each other. A hollow shaft sleeve 30 is rotatably installed on the transverse vibration table 2. The interior of the hollow shaft sleeve 30 is fixed with a first spline groove with openings at both ends and slidingly connected to the flower shaft 27. The cross sections of the first spline groove and the flower shaft 27 are both regular hexagons. The change shaft 3 is rotatably installed on the bracket 19. A second bevel gear is installed on the hollow shaft sleeve 30 and the change shaft 3. The large circular shaft 25 drives the small circular shaft 26 to rotate via the second synchronous belt, and then the first bevel gear reversing transmission is transmitted to the flower shaft 27. The flower shaft 27 drives the hollow shaft sleeve 30 to rotate synchronously through the regular hexagonal first spline groove. Finally, the second bevel gear transmits the power to the direction-changing shaft 3. The transmission chain adopts a spline sliding connection design to ensure uninterrupted power transmission when the horizontal vibration table 2 moves horizontally, solving the problem of traditional rigid transmission being prone to jamming under vibration conditions. The multi-tooth intermittent transmission system also includes a reciprocating screw 31 rotatably connected to the bracket 19 and arranged vertically. A third torsion spring 32 is fixedly provided at the rotational connection between the reciprocating screw 31 and the bracket 19. A third synchronous belt is transmission-connected between the reciprocating screw 31 and the direction-changing shaft 3. The reciprocating screw 31 is transmission-connected to the longitudinal vibration frame 4. The servo motor 17 drives the eccentric shaft 18 to rotate, and the eccentric shaft 18 drives the first incomplete gear 23 and the second incomplete gear 24 to move. The first incomplete gear 23 and the second incomplete gear 24 have different radii and different vertical heights on the eccentric shaft 18. At the same time, a power interruption area is set on the eccentric shaft 18; When the eccentric shaft 18 rotates, the first incomplete gear 23 and the second incomplete gear 24 will alternately mesh with the two differential gears 29. Due to the different radii of the upper and second incomplete gears 24 and the differential gear 29, the reciprocating screw 31 will alternately cycle to achieve a speed difference and a number of rotations. The different numbers of rotations of the reciprocating screw 31 will result in different reciprocating displacement strokes of the longitudinal vibration frame 4, ultimately achieving alternating cyclic changes in the vibration stroke of the longitudinal vibration frame 4. In the power interruption area, the differential gear 29 is in an idling state, and the large circular shaft 25 stores energy and resets under the action of the second torsion spring 28, thereby driving the direction-changing shaft 3 to realize periodic forward and reverse rotation. The third torsion spring 32 drives the reciprocating screw 31 to automatically reset, thereby forming the forward and reverse rotation of the reciprocating screw 31. The stroke change of the longitudinal vibration frame 4 drives the forward cutter cylinder 6 and the reverse cutter cylinder 7 in the material lifting cylinder 5 to rotate in opposite directions, and the differential shear frequency is formed by the swing of the cutter assembly; When the stroke increases, a stronger tearing force is applied to the hard waste. When the stroke decreases, the high-frequency small-amplitude vibration can quickly cut off the film fibers to avoid waste winding around the knife edge. The intermittent telescopic movement of the stroke enables the waste to obtain a short relaxation gap after being sheared by the knife edge, and combined with the power pause in the power interruption area, it effectively reduces the problem of tool jamming caused by continuous stress on the long-fiber waste; The vertical vibration of the longitudinal vibration frame 4 forces the waste in the spiral sieve blade 34 to move in a jumping manner. The sieve holes 35 form a dynamic opening and closing effect under the change of the vibration stroke, and the fine particles adhering to the hole wall are vibrated down to the aggregate area 12, significantly reducing the sieve hole blockage rate; During large-stroke vibration, the waste is thrown up significantly in the material lifting cylinder 5. The light film fragments pass through the sieve holes 35 first due to the inertia difference, while the heavy impurities continue to rise with the spiral sieve blade 34. Small-stroke vibration then finely sorts the residual particles to ensure the purity of the recycled materials; The automatic stroke adjustment function can adapt to the processing requirements of waste with different densities. By adjusting the residence time of the waste in the material lifting cylinder 5, the hot air can evenly penetrate the material layer, accelerating the softening or drying of the film material and improving the subsequent crushing and screening efficiency; The bottom surface of the longitudinal vibration frame 4 is equipped with a material lifting cylinder 5, and a screening and lifting system for circulating and lifting the waste from bottom to top and screening the waste is arranged in the material lifting cylinder 5; The forward cutter cylinder 6 and the reverse cutter cylinder 7 are respectively rotatably sleeved on the material lifting cylinder 5 from top to bottom, and the forward cutter cylinder 6 and the reverse cutter cylinder 7 rotate coaxially in opposite directions; The screening and lifting system includes a lifting shaft 33 rotatably installed in the material lifting cylinder 5. The top of the lifting shaft 33 is fixedly provided with a top opening and a second spline groove slidably connected to the steering shaft 3. The cross-sections of the second spline groove and the steering shaft 3 are both regular hexagons. A spiral sieve blade 34 is installed on the lifting shaft 33. The spiral sieve blade 34 fits with the material lifting cylinder 5. The spiral sieve blade 34 is evenly distributed with vertically arranged sieve holes 35. A group of discharge ports 36 distributed in a circumferential array are opened in the upper part of the material lifting cylinder 5. A group of return ports 37 distributed in a circumferential array are opened in the lower part of the material lifting cylinder 5 corresponding to the aggregate area 12. An open-mouth material leakage section is arranged on the forward cutter cylinder 6 corresponding to the discharge port 36. A feed nozzle 46 is connected to the tank body 1; The steering shaft 3 drives the lifting shaft 33 to rotate through the second spline groove. The spiral sieve blade 34 conveys the vehicle-mounted film waste in the aggregate area 12 from bottom to top. The sieve holes 35 intercept the large-particle vehicle-mounted film waste. The qualified particles enter the crushing area through the discharge port 36, and the unqualified particles are circularly screened through the return port 37. This process forms a "lifting - screening - return" closed loop. A plurality of cutter assemblies are installed on both the forward cutter cylinder 6 and the reverse cutter cylinder 7; When the spiral sieve blade 34 is working, even if the lifting shaft 33 rotates in the reverse direction, the vertical vibration of the longitudinal vibration frame 4 will still assist the jumping movement of the waste material. Combined with the dynamically opened and closed sieve holes 35, it ensures that the waste material continuously moves upward in the material lifting cylinder 5. The periodic stroke change of the longitudinal vibration frame 4 is adjusted by the reciprocating lead screw 31. The large-stroke vibration can force the waste material to overcome the resistance brought by the reverse rotation, while the small-stroke high-frequency vibration offsets the negative impact of the reverse rotation on the lifting through dynamic screening.

[0024] In addition, the design of the material return port 37 allows unqualified particles to re-enter the cycle, avoiding material accumulation caused by short-term reverse rotation. The power interruption area in the multi-tooth intermittent transmission system provides a stage without power transmission for the reversing shaft 3. At this time, the short-term stop of the lifting shaft 33 maintains the lifting state of the waste material through the inertia and vibration of the spiral sieve blade; The tool assembly includes a tool holder 8 and a fixed tooth ring 9. The positive cutter cylinder 6 and the reverse cutter cylinder 7 are both fixedly connected to the tool holder 8 at corresponding positions. A tool shaft 10 that can reciprocate within a set angle is rotatably installed on the tool holder 8. A first torsion spring 11 is fixedly arranged at the rotational connection of the tool shaft 10 and the tool holder 8. A driven bevel gear is installed at the tail end of the tool shaft 10. The fixed tooth ring 9 is fixedly installed on the material lifting cylinder 5. Multiple bevel gear surfaces and multiple toothless surfaces are arranged on the fixed tooth ring 9. The bevel gear surfaces are adaptively connected to the driven bevel gear. A moving cutting edge 16 is installed on the tool shaft 10; The number of bevel gear surfaces and toothless surfaces is the same, and the central angles corresponding to the bevel gear surfaces and toothless surfaces are the same. The multiple bevel gear surfaces and multiple toothless surfaces are arranged at intervals of two on the fixed tooth ring 9; The positive cutter cylinder 6 and the reverse cutter cylinder 7 rotate coaxially in opposite directions. The driven bevel gear on the tool shaft 10 reciprocates along the bevel gear surface of the fixed tooth ring 9. The first torsion spring 11 provides a reset torque, enabling the moving cutting edge 16 to perform "impact-shear" composite crushing on the vehicle-mounted film waste material. The fixed cutting edge 13 at the bottom of the reverse cutter cylinder 7 synchronously performs secondary crushing on the falling material. Compared with the traditional fixed blade structure, the crushing efficiency and refinement degree are significantly improved; When the longitudinal vibration frame 4 moves vertically, the steering shaft 39 drives the positive cutter cylinder 6 and the reverse cutter cylinder 7 to rotate synchronously through the steering bevel gear. The belt shaft 40 drives the lifting shaft 33 to rotate through the fourth synchronous belt and the linkage gear 41, forming a "vibration-rotation" linkage mechanism. The sleeve 42 is connected to the rotating seat 38 and the reverse cutter cylinder 7 through a connecting plate. The sealing ring cotton 43 prevents dust leakage. This design realizes the multi-action coordination of the material lifting cylinder 5 lifting, the cutter group crushing, and the sieve blade rotating. For example, when processing vehicle-mounted heat insulation film waste material with adhesives, the vibration of the longitudinal vibration frame 4 can break the adhesive connection. The synchronously rotating cutter group and sieve blade quickly complete crushing and screening. Compared with the traditional step-by-step processing device, the efficiency is increased by more than 50%, and the sealing structure reduces the dust concentration in the working environment to below 8 mg / m³, meeting the environmental protection requirements; The knife shaft 10 meshes with the conical tooth surface of the fixed gear ring 9 through the driven bevel teeth, and swings back and forth under the action of the first torsion spring 11, driving the movable knife edge 16 to apply alternating shear force and impact force to the waste. The coaxial counter-rotation of the positive knife cylinder 6 and the reverse knife cylinder 7 further expands the knife edge motion trajectory, forming a "saw-like" tearing effect, which is particularly suitable for the ductile material of vehicle-mounted film waste, avoiding stretching and winding of the film due to unidirectional cutting; The "point-surface" alternating contact mode of the oscillating blade applies multi-directional shearing force to the long-fiber waste, physically destroying the continuous structure of the fibers and significantly reducing the probability of film wrapping around the blade shaft 10; The reciprocating motion of the blade disperses the wear area of the cutting edge. Combined with the intermittent design of the fixed gear ring 9 without tooth surface, it reduces the ineffective friction between the blade and the waste material, and prolongs the life of the blade by 2 times compared with traditional fixed blades. It also includes a sleeve 42 and a rotary seat 38 rotatably sleeved on the positive knife cylinder 6, a group of connecting plates are installed between the sleeve 42, the rotary seat 38 and the reverse knife cylinder 7, a passive bevel gear is installed on the rotary seat 38 and the positive knife cylinder 6, a steering shaft 39 is rotatably installed on the longitudinal vibration frame 4, a steering bevel gear is installed on the steering shaft 39, two passive bevel gears are connected to the steering bevel gear, and the two passive bevel gears are respectively arranged on both sides of the steering bevel gear, a belt shaft 40 is rotatably installed on the longitudinal vibration frame 4, a fourth synchronous belt is connected between the belt shaft 40 and the lifting shaft 33, and a linkage gear 41 is installed on the belt shaft 40 and the lifting shaft 33, and the two linkage gears 41 are meshed with each other; The sleeve 42 is a hollow cylindrical structure with two ends open. A sealing ring 43 is installed between the sleeve 42 and the tank body 1. The sealing ring 43 is made of sponge. Sleeve 42 and rotary seat 38 are connected to counter-knife cylinder 7 via a connecting plate, forming a dynamic seal. Combined with the sponge-made sealing ring 43, this effectively prevents waste powder from escaping. The silicone collection cover 14 is both flexible and heat-resistant, adapting to the hot air environment within tank 1 and ensuring centralized collection of crushed waste particles. This sealing solution solves the dust pollution problem of traditional open recycling devices, meets the environmental protection requirements of vehicle film production workshops, and reduces cleaning and maintenance costs. A gathering area 12 is provided at the bottom of the tank body 1, and multiple sets of fixed blades 13 are installed on the counter-knife cylinder 7 and at the position corresponding to the gathering area 12. An aggregate rubber cover 14 is installed at the bottom of the gathering area 12. The aggregate rubber cover 14 is fixedly connected to the lifting cylinder 5 and is made of silicone.

[0025] The aggregate rubber cover 14 made of silica gel material elastically fits the bottom of the aggregate area 12, and collects the broken in-vehicle film waste along with the vibration of the material lifting cylinder 5. Its flexible structure can buffer the impact of particles and prevent the sharp in-vehicle film waste from piercing the equipment. This design aims at impurities such as metal debris and hard particles that may be contained in the in-vehicle film waste, and avoids the wear problem of the traditional rigid aggregate hopper through the flexible aggregate structure, extending the service life of the device to more than 5000 hours. Compared with the metal aggregate component, the maintenance cycle is extended by 3 times, significantly reducing the maintenance cost in industrial applications; At the top of the tank body 1, there is a heat supply component 15 for supplying heat to the inner cavity of the tank body 1; The heat supply component 15 includes a wind cylinder installed on the tank body 1. The bottom end of the wind cylinder is communicated with the inner cavity of the tank body 1. A filter element and an electric hot air blower are sequentially installed on the inner wall of the wind cylinder from top to bottom. A temperature probe 44 for monitoring the temperature of the inner cavity of the tank body 1 is installed on the tank body 1, and a central control host 45 is installed on the end face of the tank body 1. The data end of the temperature probe 44 is data-connected to the central control host 45.

[0026] The hot air blower conveys hot air into the tank through the wind cylinder, and the filter element filters impurities in the air. The heat supply component 15 controls the hot air temperature at 60°C - 120°C through the electric hot air blower. The hot air penetrates the waste layer, reducing the intermolecular force of the polymer chains, making the film more brittle and easier to break. The resistance during the shearing of the softened waste by the tool assembly is significantly reduced, and the broken particle size is more uniform. The hot air improves the fluidity of the waste and reduces the residue rate of the waste on the cutting edge through the wind force; The working principle and usage process of the present invention: The servo motor 17 drives the eccentric shaft 18 to rotate through the first synchronous belt. The eccentric wheel 20 cooperates with the roller 21 of the horizontal vibration table 2. Under the action of the reset elastic element 22 and the guide rail frame, the horizontal vibration table 2 vibrates horizontally back and forth, driving the moving cutting edge 16 and the fixed cutting edge 13 to move horizontally, so as to realize the rotary cutting, cross-cutting and shaking off of the waste material. The eccentric shaft 18 drives the first incomplete gear 23 and the second incomplete gear 24 to alternately engage with the differential gear 29. By using the gear radius and height difference and the second torsion spring 28, the large circular shaft 25 drives the reversing shaft 3 to rotate periodically forward and backward. At the same time, through the intermittent transmission in the power interruption area, tool jamming is avoided and the shear force is dynamically changed. The reversing shaft 3 drives the lifting shaft 33 to rotate through the second spline groove. The spiral sieve blade 34 conveys the waste material from bottom to top, and the sieve holes 35 screen the waste material. The qualified particles enter the crushing area through the discharge port 36, and the unqualified particles are circularly screened through the return port 37. The positive cutter cylinder 6 and the negative cutter cylinder 7 rotate coaxially and in opposite directions. The driven bevel gear on the cutter shaft 10 swings back and forth along the conical tooth surface of the fixed tooth ring 9, so that the moving cutting edge 16 performs "impact-shearing" composite crushing on the waste material, and the fixed cutting edge 13 at the bottom of the negative cutter cylinder 7 performs secondary crushing on the falling material. When the vertical vibration frame 4 moves vertically, the steering shaft 39 drives the positive cutter cylinder 6 and the negative cutter cylinder 7 to rotate synchronously, and the belt shaft 40 drives the lifting shaft 33 to rotate, forming a "vibration-rotation" linkage. The electric hot air blower of the heat supply part 15 controls the hot air temperature at 60°C - 120°C and sends it into the tank to soften the waste material for easy crushing. The temperature probe 44 monitors the temperature and feeds it back to the central control host 45. Finally, the crushed waste material particles are collected by the silica gel aggregate rubber cover 14 in the aggregate area 12. The whole process realizes the cyclic lifting, screening, crushing and heat softening treatment of the waste material, improving the recycling efficiency and quality.
