Description

Technical Field

[0001] This invention relates to the field of thin film equipment, and more particularly to a thin film recycling and processing apparatus and its processing method. Background Technology

[0002] After the film is used up, it needs to be recycled and reused. The waste film needs to be crushed, melted and granulated, and the waste particles and new particles are mixed in a certain proportion and processed into film by extrusion casting.

[0003] To ensure film quality, it is necessary to ensure uniform mixing between waste and virgin materials. Therefore, the waste is granulated and mixed with the granulated virgin materials. The waste needs to be crushed and then melted and granulated, and the virgin materials also need to be melted and granulated, which results in low efficiency of film recycling and processing, and high cost of producing materials in granular form.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide a film recycling processing device and processing method to solve the problem that the efficiency of film recycling processing is low in the prior art because waste materials need to be crushed and then melted and granulated, and new materials also need to be melted and granulated.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: Thin film recycling and processing equipment; It includes: a mesh-making device, a cutting device for rolling and cutting recycled material, a first rolling mechanism for hot rolling of the mesh, a heating device for heating the mesh, a second rolling mechanism for rolling the mesh, and a recycling mechanism for recycled film; wherein, the mesh-making device weaves new material lines and recycled lines into a mesh; the second rolling mechanism is rotatably mounted on the heating device; the first rolling mechanism and the recycling mechanism are located on both sides of the heating device.

[0007] A further technical solution is that the cutting device includes: a conveying device, a first roller arranged in parallel and rotating manner, a second roller for conveying recycled material, a cutting disc for cutting recycled material, and a spool for storing the recycled material; wherein, the first roller rolls the recycled material into a flat shape; the cutting disc is arranged in parallel and rotating manner between the second rollers; the second roller rotates to convey the recycled material to the conveying device, and the conveying device conveys the recycled material to the spool.

[0008] A further technical solution is that the net-making device includes: parallel weaving rods, a spraying cylinder connected to an air source, and a clamping mechanism disposed on both sides of the weaving rods; wherein, new material thread passes through the weaving rods; adjacent weaving rods move back and forth alternately, causing adjacent new material threads to be stretched alternately; the spraying cylinder sprays a recycled line that passes between adjacent new material threads; the clamping mechanism clamps the recycled line and moves it between adjacent new material threads.

[0009] A further technical solution is that the first rolling mechanism includes: a first rolling support, a first rolling shaft rotatably disposed on the first rolling support, and a first heating tube disposed inside the first rolling shaft; wherein, the first heating tube heats the first rolling shaft, and the first rolling shaft hot rolls the overlapping position of the new material line and the recycling line.

[0010] A further technical solution is that a swing plate is oscillating on the first rolling support; cutting teeth are formed on the swing plate, and a first elastic device is sleeved at the swing position of the swing plate; when the material net moves, the first elastic device pushes the swing plate to contact the material net, and the cutting teeth cut the material net.

[0011] A further technical solution is that the heating device includes: a heating channel, a second heating tube, a heating plate, and a fan; wherein, the second rolling mechanism is rotatably arranged between adjacent second heating tubes; the second heating tube and the heating plate are arranged side by side in the heating channel; the fan generates gas that passes through the second heating tube to form hot gas, part of which flows through the heating plate and acts on the material mesh; the other part of the hot gas flows through the second rolling mechanism.

[0012] A further technical solution is that the second rolling mechanism includes a protruding strip and a second rolling shaft rotatably disposed within the heating channel; wherein the protruding strip is disposed on the second rolling shaft in the material mesh moving direction; the thickness of the protruding strip gradually decreases along the material mesh moving direction; and the shape of the protruding strip transitions from an angle to a curve along the material mesh moving direction.

[0013] A further technical solution is that the recycling mechanism includes: a recycling bracket, recycling rollers rotatably mounted on the recycling bracket, a cooler mounted on the recycling bracket, and a recycling film cylinder; wherein the film is sequentially wound around each of the recycling rollers, the suction end of the cooler faces the film, and the film is wound on the cylinder.

[0014] The processing method of the thin film recycling processing device includes the following steps: Cutting steps: The recycled material is fed into the first roller and rolled into a flat shape. The cutting disc cuts the recycled material into several recycling lines, which are then conveyed to the spool by a conveying device. Weaving steps: Adjacent weaving rods move back and forth alternately, causing adjacent new material threads to be stretched up and down alternately. The spraying tube sprays the recycled thread through the space between adjacent new material threads. The clamping mechanism clamps the recycled thread and moves it between adjacent new material threads. The recycled thread and new material threads are woven into a mesh. Shaping and cutting steps: The first heating tube heats the first rolling shaft to the set temperature, and the first rolling shaft hot rolls the overlapping position of the new material line and the recycling line; the first elastic device pushes the swing plate to contact the material mesh, and the cutting teeth cut the material mesh; Processing steps: The mesh passes through the heating channel, and the gas is heated by the second heating tube. Part of the hot gas flows through the heating plate and acts on the mesh; the other part of the hot gas flows through the second rolling mechanism. When the mesh is moved in, the second rolling shaft rolls the mesh, and the convex strips fold and press the mesh. When the mesh is moved out, the second rolling shaft rolls the mesh into a thin film. Recycling steps: The film is wound around each recycling roller and moves, the cooler absorbs the heat of the film, and the film is wound onto the roller for recycling.

[0015] Compared with the prior art, the beneficial technical effects of the present invention are as follows: (1) The material mesh is hot-rolled by the first rolling mechanism, and the overlapping position of the new material line and the recycled line is hot-pressed, and the overlapping position of the new material line and the recycled line is fused. The compressive strength of the material mesh is improved by hot-pressing and fixing the node position of the material mesh. The recycling line is made into a film, which reduces the granulation process. Similarly, the new material does not need to be granulated. The new material can be made into a line. The new material line and the recycled line are woven by the mesh making device. The thickness of the film is controlled according to the weaving density. The ratio of new material and recycled amount is controlled according to the amount of new material and recycled line. Since the new material line and the recycled line are woven into a mesh, the mesh can be filled to form a complete film by heating by the heating device and rolling by the second rolling mechanism. The film making can be completed without the extrusion casting process.

[0016] (2) When the tension on the new material line is too large, the new material line pulls on the weaving rod and the rod frame, causing the weaving rod and the rod frame to rotate in opposite directions. The tension on the new material line is less, and the tension on the new material line is less. The second elastic device reapplies the rotational elastic force to the weaving rod and the rod frame, and the rod frame re-tensions the new material line, thereby preventing the new material line from breaking due to excessive tension. The sleeve rotates along the spray cylinder, causing the first cylinder opening and the second cylinder opening to be misaligned. The outer periphery of the spray cylinder is in a sealed state, which facilitates the spraying of the medium and the recovery line, and avoids leakage. The recovery line can be smoothly fed into the new material line by clamping the clamping frame and the mating frame, and the length of the recovery line is controlled by cutting off both ends of the recovery line by cutting the blocks. An area for the recovery line to pass through is formed between the two sets of extension plates. The end of the extension plate away from the thin plate extends closer to each other, preventing the recovery line from leaving the two sets of extension plates.

[0017] (3) The first rolling shaft is driven to rotate by a motor. The first rolling shaft hot rolls the overlapping position of the new material line and the recycling line, so that the overlapping position of the new material line and the recycling line merges and the mesh becomes a whole. After the mesh is stretched, the whole is distributed to distribute the force, which improves the tensile performance of the mesh. When the mesh moves, the first elastic device pushes the swing plate to contact the mesh, and the cutting teeth cut the mesh. The cutting teeth cut a cut on the mesh. The mesh continues to move, which makes the cutting teeth expand the cut. The cutting direction of the cut forms a material edge cut from the mesh. The material edge is still connected to the mesh and is not broken. The material edge covers the mesh hole. When the heating device and the second rolling mechanism in the subsequent process heat and roll the mesh, the material edge can quickly melt and cover the mesh hole, avoiding the appearance of voids in the film.

[0018] (4) The gas generated by the blower passes through the second heating tube to form hot gas. Part of the hot gas flows through the heating plate and acts on the material mesh from both the top and bottom directions. The material mesh is heated and melts quickly on both the top and bottom sides at the same time. Another part of the hot gas flows through the second rolling mechanism. The second rolling mechanism is heated and maintains a certain temperature to avoid the temperature difference being too large when the second rolling mechanism contacts the material mesh, which would affect the film formation. After the other part of the hot gas flows through the second rolling mechanism, it enters the adjacent second heating tube to heat up again. The other part of the hot gas continues to flow through the heating plate and acts on the material mesh from both the top and bottom directions. The combination of one part of the hot gas and the other part of the hot gas acting on the material mesh from both the top and bottom directions ensures that a certain amount of hot gas acts on the material mesh, so that the material mesh can be heated and melted quickly.

[0019] (5) When the second rolling shaft rolls the mesh, the convex strip acts on the mesh, and the convex strip bends the mesh back and forth to stretch it. The new material line and the recycling line can quickly cover the mesh to form a film. As the film gradually takes shape, the thickness of the convex strip gradually decreases along the direction of mesh movement, and the shape of the convex strip transitions from sharp corners to curves along the direction of mesh movement, reducing the stretching of the film by the convex strip. The degree of bending of the film gradually decreases, and the film gradually forms a plane. Attached Figure Description

[0030] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0031] Figure 1 A top view of the thin film recycling and processing apparatus according to a first embodiment of the present invention is shown. (Combined with...) Figure 1As shown, the present invention discloses a film recycling processing apparatus comprising: a screen making device 2, a cutting device 1 for rolling and cutting recycled material, a first rolling mechanism 3 for hot rolling of the screen, a heating device 4 for heating the screen, a second rolling mechanism 5 for rolling the screen, and a recycling mechanism 6 for recycled film.

[0032] In this process, recycled material is fed into the cutting device 1 and cut into recycled wires. Then, the new material wires and recycled wires are woven into a mesh by the mesh-making device 2. The second rolling mechanism 5 pulls on the mesh, causing deformation. The first rolling mechanism 3 then heat-rolls the mesh, pressing the overlapping positions of the new material wires and recycled wires to fuse them together. By fixing the mesh nodes with heat, the compressive strength of the mesh is improved.

[0033] The first rolling mechanism 3 and the recycling mechanism 6 are located on both sides of the heating device 4. The heated mesh passes through the heating device 4, which simultaneously heats both the upper and lower surfaces of the mesh. The second rolling mechanism 5 is rotatably mounted on the heating device 4, and is spaced apart on both the upper and lower sides of the heating device 4. The second rolling mechanism 5 simultaneously rolls both the upper and lower surfaces of the mesh. After the mesh melts, the new material line and the recycling line fill the mesh openings to form a thin film. The film is wound around the recycling mechanism 6 for stretching and cooling before being recycled.

[0034] The recycling of film does not involve turning the film into granules, nor does it involve mixing virgin and recycled granules and then casting them into film. Instead, the film is made into a recycling line, reducing the granulation process. Similarly, virgin material does not need to be granulated; it can be made into a thread. The virgin and recycled material threads are woven together by the mesh-making device 2. The film thickness is controlled by the weaving density, and the ratio of virgin to recycled material is controlled by the amount of virgin and recycled material used. Since the virgin and recycled material threads are woven into a mesh, only heating by the heating device 4 and rolling by the second rolling mechanism 5 are needed to fill the mesh and form a complete film, eliminating the need for extrusion casting.

[0035] Figure 2 This diagram shows a right-side view of the cutting device 1 according to a first embodiment of the present invention. (In conjunction with...) Figure 1 and Figure 2 As shown, the cutting device 1 includes: a conveying device 11, a first roller 12 arranged in parallel and rotating, a second roller 14 for conveying recycled material, a cutting disc 15 for cutting recycled material, and a spool 17 for storing recycled material.

[0036] The first rollers 12 are arranged in a vertical group, and multiple groups of first rollers 12 are distributed in the direction of material movement. The spacing between the first rollers 12 in a group gradually decreases, so that after the recycled material passes through multiple groups of first rollers 12, the thickness of the recycled material reaches the set thickness. After the first rollers 12 flatten the recycled material, the recycled material continues to move closer to the second rollers 14.

[0037] Combination Figure 2 As shown, the cutting device 1 further includes a cutter 18. The cutter 18 is located between the first rollers 12, and is inclinedly mounted on the cutting frame 181. The end of the cutter 18 is close to the first roller 12, so that after the recycled material is cut, the subsequent recycled material is located close to the first roller 12, and the subsequent recycled material continues to be rolled by the first roller 12. The cutting frame 181 is driven by an electric cylinder to reciprocate, so that the cutter 18 reciprocates to complete the length cutting of the recycled material.

[0038] Cutting discs 15 are arranged in parallel and rotate between the second rollers 14. The cutting discs 15 are also arranged in parallel on a shaft 151, which is driven by a motor. The second rollers 14 convey the recycled material, which is then cut into several strips of recycled material after passing through the cutting discs 15. The width of the recycled material can be adjusted by changing the position of the cutting discs 15 on the shaft 151 and adjusting the spacing between them.

[0039] The conveying device 11 includes a belt conveyor 111, a conveying support 112 movably mounted on the belt conveyor 111, and a bracket 113 oscillatingly mounted on the conveying support 112. The bracket 113 is rotatably connected to the conveying support 112 at both ends, and the bracket 113 is driven to oscillate by a motor.

[0040] A linear motion module is installed on the conveyor support 112, which drives the bracket 113 to move along the conveyor support 112. The second roller 14 rotates to convey the recycling line to the conveyor device 11, and the conveyor device 11 conveys the recycling line to the spool 17.

[0041] The conveyor bracket 112 moves closer to the second roller 14, the bracket 113 swings upward, the second roller 14 rotates to convey one end of the recycling line onto the bracket 113, the second roller 14 continues to rotate and convey, the bracket 113 moves away from the second roller 14 along the belt conveyor 111, the other end of the recycling line is placed on the belt conveyor 111, the bracket 113 swings downward to place the recycling line completely on the belt conveyor 111, the belt conveyor 111 conveys the recycling line to the spool 17.

[0042] Figure 3 A front view structural schematic diagram of the bobbin according to the first embodiment of the present invention is shown. (In conjunction with...) Figures 1-3As shown, the spool 17 includes a spool body 171, an arc plate 172 disposed along the outer surface of the spool body 171, and troughs 173 arranged side-by-side around the spool body 171. The arc plate 172 contacts the spool body 171, the upper end of the spool body 171 is close to the belt conveyor 111, and the lower end of the spool body 171 is close to the wire mesh making device 2. The recycling lines are placed in the respective troughs 173, separating and conveying the recycling lines. The arc plate 172 prevents the recycling lines from detaching from the troughs 173 during transport.

[0043] Figure 4 A front view structural schematic diagram of the position of the injection cylinder according to the first embodiment of the present invention is shown. Figure 5 A front view structural schematic diagram of the webbing rod position according to the first embodiment of the present invention is shown. Figure 6 A front view schematic diagram of the clamping mechanism according to a first embodiment of the present invention is shown. (In conjunction with...) Figures 4-6 As shown, the web-making device 2 includes: parallel weaving rods 21, a jetting cylinder 22 connected to an air source, and clamping mechanisms 23 disposed on both sides of the weaving rods 21. The weaving rods 21 are arranged parallel to each other within a rod frame 211. For example, there are two sets of rod frames 211. New material thread passes through the weaving rods 21, and the two sets of rod frames 211 move up and down alternately, enabling adjacent weaving rods 21 to move back and forth alternately, thus driving adjacent new material threads to stretch alternately. A rod plate 212 is formed on the weaving rod 21, and a window 213 is formed on the rod plate 212. The edges of the window 213 are rounded to prevent the edges of the window 213 from scratching the new material thread. The weaving rods 21 are rotatably connected to the rod frames 211, and a second elastic device 314 is sleeved on the weaving rods 21. The second elastic device 314 applies a rotational elastic force to the weaving rods 21 and the rod frames 211, and the rod frames 211 exert a pulling force on the new material thread to tighten it. When the tension on the new thread is too great, the new thread pulls on the weaving rod 21 and the frame 211, causing the weaving rod 21 and the frame 211 to rotate in opposite directions. The tension on the new thread is reduced by the frame 211, and the second elastic device 314 applies a rotational elastic force to the weaving rod 21 and the frame 211 again. The frame 211 then re-tensions the new thread, thereby preventing the new thread from breaking due to excessive tension.

[0044] Combination Figure 5 As shown, the net-making device 2 also includes a rotatably mounted power shaft 24, on which multiple sets of shaft blocks 241 are eccentrically connected. Each shaft block 241 is hinged with a rod 242, which in turn is hinged to a frame 211. Different shaft blocks 241 are connected to different frames 211 via the rods 242.

[0045] The eccentric angle of the shaft block 241 is deviated, so that when one set of shaft blocks 241 pulls the rod frame 211 down through the block rod 242, the other set of shaft blocks 241 pushes the rod frame 211 up through the block rod 242. The power shaft 24 is driven to rotate by the motor, thereby driving the rod frame 211 to move up and down reciprocally.

[0046] The spray cylinder 22 sprays the recycling line through the space between adjacent new material lines. A notch is formed near the reel 17 in the spray cylinder 22 to allow the recycling line to be inserted. The spray cylinder 22 can supply the recycling line to a single reel 17, or it can alternately supply the recycling line to two reel 17, thus improving the efficiency of the spray cylinder 22 in supplying the recycling line.

[0047] Combination Figure 6 As shown, the clamping mechanism 23 is oscillatingly mounted on the screen-making device 2. The clamping mechanism 23 clamps the recycling line and moves it between adjacent new material lines. The clamping mechanism 23 includes a rotatably mounted clamping shaft 231, clamping frames 232 fixed at both ends of the clamping shaft 231, a oscillatingly mounted mating frame 233 on the screen-making device 2, and a limiting block 234 mounted above the clamping shaft 231. An eccentric block 235 is rotatably mounted on the screen-making device 2. The eccentric block 235 is driven to rotate by a motor and is eccentrically connected to the drive end of the motor. A third elastic device 236 is provided on the screen-making device 2, which pushes the clamping frame 232 and the mating frame 233 to reset. Both the clamping frame 232 and the mating frame 233 are equipped with cutting blocks 237. There is a positional mismatch between the cutting blocks 237 on the clamping frame 232 and the cutting blocks 237 on the mating frame 233 in the front-back direction, so that there is a gap between them in the front-back direction. The length of the gap is less than the thickness of the recycling line, so that the cutting blocks 237 on the clamping frame 232 and the cutting blocks 237 on the mating frame 233 can clamp the recycling line, and the movement of the two does not cause interference.

[0048] Combination Figure 2 As shown, the nozzle of the spray tube 22 is connected to the medium source via pipe 221, and an acute angle is formed between pipe 221 and spray tube 22. Since the recovery line is strip-shaped, the shape of the nozzle of the spray tube 22 corresponds to the cross-sectional shape of the recovery line, thus preventing the recovery line from overturning during the spraying process.

[0049] Combination Figure 4 As shown, a first nozzle 222 is formed on the spray cylinder 22, and a sleeve 223 is rotatably mounted on the spray cylinder 22. A second nozzle 224 is formed on the sleeve 223. A toothed segment 225 is provided along the outer surface of the spray cylinder 22, and a gear 226 is rotatably mounted on the sleeve 223. The first nozzle 222 corresponds to the spool 17. The sleeve 223 is designed to avoid obstructing the pipe 221.

[0050] The gear 226 is driven by a motor and rolls along the tooth segment 225. The sleeve 223 rotates along the spray cylinder 22, causing the first cylinder opening 222 and the second cylinder opening 224 to overlap. The recycled line in the spool 17 is placed in the spray cylinder 22 through the first cylinder opening 222 and the second cylinder opening 224. The sleeve 223 rotates along the spray cylinder 22, causing the first cylinder opening 222 and the second cylinder opening 224 to be misaligned. The outer periphery of the spray cylinder 22 is in a sealed state, which facilitates the spraying of the medium and the recycled line by the spray cylinder 22 and avoids leakage.

[0051] The spray nozzle 22 sprays the recycling line. After the recycling line passes between the new material lines, both ends of the recycling line are placed between the clamping frame 232 and the mating frame 233. The motor drives the eccentric block 235 to rotate, and the eccentric block 235 pushes the clamping frame 232 closer to the mating frame 233. The cutting blocks 237 on the clamping frame 232 and the mating frame 233 clamp the recycling line. The eccentric block 235 pushes the clamping frame 232 and the mating frame 233 to continue swinging. The clamping frame 232 and the mating frame 233 send the recycling line into the new material lines. At this time, the mating frame 233 contacts the limiting block 234. The mating frame 233 stops swinging, and the clamping frame 232 continues to swing, cutting off both ends of the recycling line. The eccentric block 235 continues to rotate and disengages from the clamping frame 232. The third elastic device 236 pushes the clamping frame 232 and the mating frame 233 to reset. The recycling line can be smoothly fed into the new material line by clamping the recycling line with the clamping frame 232 and the mating frame 233, and the length of the recycling line can be controlled by cutting off both ends of the recycling line with the cutting block 237.

[0052] Combination Figure 6 As shown, to ensure the recycling line can move along the virgin material line, the spraying movement area of ​​the recycling line needs to be restricted. Thin sheets 238 are arranged side-by-side between the clamping frames 232, with the virgin material line passing between adjacent sheets 238 to prevent the movement of the sheets 238 from interfering with the virgin material line. Two sets of extension pieces 239 are formed on the sides of the sheets 238, creating an area between the two sets of extension pieces 239 for the recycling line to pass through. The ends of the extension pieces 239 furthest from the sheets 238 extend closer to each other to prevent the recycling line from detaching from the space between the two sets of extension pieces 239.

[0053] Figure 7 A front view schematic diagram of the first rolling mechanism according to a first embodiment of the present invention is shown. (Combined with...) Figure 7 As shown, the first rolling mechanism 3 includes: a first rolling support 31, a first rolling shaft 32 rotatably mounted on the first rolling support 31, and a first heating tube 33 disposed within the first rolling shaft 32. The first rolling shaft 32 has a hollow internal structure, and two sets of first rolling shafts 32 are distributed vertically. The first heating tube 33 extends into the lower end of the upper first rolling shaft 32 and the upper end of the lower first rolling shaft 32, heating the lower end of the upper first rolling shaft 32 and the upper end of the lower first rolling shaft 32.

[0054] The first rolling shaft 32 is driven to rotate by a motor. The first rolling shaft 32 hot rolls the overlapping position of the new material line and the recycling line, so that the overlapping position of the new material line and the recycling line merges and makes the mesh a whole. When the mesh is stretched, the force is distributed as a whole, which improves the tensile strength of the mesh.

[0055] A swing plate 34 is oscillatingly mounted on the first rolling support 31. Cutting teeth 35 are formed on the swing plate 34, and a first elastic device 36 is fitted onto the swing position of the swing plate 34. For example, the first elastic device 36 is a spring. The cutting teeth 35 are inclined in the direction of material mesh insertion. The cutting teeth 35 can be straight teeth in the front-to-back direction, or they can be oblique teeth inclined to the left or right.

[0056] As the mesh moves, the first elastic device 36 pushes the swing plate 34 to contact the mesh, and the cutting teeth 35 cut the mesh. The cutting teeth 35 make a cut on the mesh, and as the mesh continues to move, the cutting teeth 35 enlarge the cut. An edge is formed from the mesh in the cutting direction of the cut. The edge remains connected to the mesh and does not break off. The edge covers the mesh openings. When the heating device 4 and the second rolling mechanism 5 heat and roll the mesh in subsequent processes, the edge can quickly melt and cover the mesh openings, preventing voids from forming in the film.

[0057] When the cutting tooth 35 is a straight tooth, it pushes the material edge to the left to cover the mesh. When the cutting tooth 35 is a slanted tooth, it pushes the material edge to the left front or left rear to cover the mesh. The cutting teeth 35 on the swing plate 34 alternate between straight and slanted teeth, so that the material edge can evenly cover the surrounding mesh.

[0058] Figure 8 A front view schematic diagram of the heating device and the second rolling mechanism according to the first embodiment of the present invention is shown. (Combined with...) Figure 8 As shown, the heating device 4 includes a heating channel 41, a second heating tube 42, a heating plate 43, and a fan 44. The heating channel 41 extends through the material mesh in a left-right direction, and the second rolling mechanism 5 is rotatably disposed between adjacent second heating tubes 42, with the heating channel 41 covering the second rolling mechanism 5.

[0059] The second heating tube 42 and the heating plate 43 are arranged side by side in the heating channel 41, distributed vertically. The heating plate 43 is located between the second heating tube 42 and the material mesh, and through holes are formed on the heating plate 43 to allow hot gas to pass through. The fan 44 is located on the side of the heating channel 41. The fan 44 generates gas that passes through the second heating tube 42 to form hot gas. Part of the hot gas flows through the heating plate 43 and acts on the material mesh from both above and below, causing the material mesh to melt rapidly on both sides simultaneously. The other part of the hot gas flows through the second rolling mechanism 5. The second rolling mechanism 5 is maintained at a certain temperature after being heated to avoid excessive temperature difference when it contacts the material mesh, which would affect film formation.

[0060] Another part of the hot gas flows through the second rolling mechanism 5 and then enters the adjacent second heating tube 42 to heat up again. Another part of the hot gas continues to flow through the heating plate 43 and acts on the material mesh from both the top and bottom. One part of the hot gas and another part of the hot gas act on the material mesh from both the top and bottom, ensuring that a certain amount of hot gas acts on the material mesh, so that the material mesh can be heated and melted quickly.

[0061] Combination Figure 8 As shown, the second rolling mechanism 5 includes a protruding strip 52 and a second rolling shaft 51 rotatably disposed within the heating channel 41. The protruding strip 52 is disposed on the second rolling shaft 51 in the direction of mesh feeding. The cross-section of the protruding strip 52 is square. When the second rolling shaft 51 rolls the mesh, the protruding strip 52 acts on the mesh, repeatedly bending and stretching it. New and recycled wires can quickly cover the mesh openings to form a film. As the film gradually takes shape, the thickness of the protruding strip 52 gradually decreases along the mesh's moving direction, and the shape of the protruding strip 52 transitions from sharp angles to curves along the mesh's moving direction, reducing the stretching effect of the protruding strip 52 on the film. The degree of film bending gradually decreases, and the film gradually forms a flat surface.

[0062] Figure 9 A front view schematic diagram of the recycling mechanism according to a first embodiment of the present invention is shown. (In conjunction with...) Figure 9 As shown, the recycling mechanism 6 includes: a recycling support 61, recycling rollers 62 rotatably mounted on the recycling support 61, a cooler 63 mounted on the recycling support 61, and a film collection frame 64. The film is sequentially wound around each recycling roller 62. Changing the direction of movement of the film causes it to flip over during movement. The suction end of the cooler 63 faces the film, and the cooler 63 can act on both sides of the film sequentially to completely cool it. An exhaust port 611 is formed on the recycling support 61, located at the discharge end of the cooler 63, for dissipating heat from the film. The film moves along one side of the recycling support 61 and is discharged through the exhaust port 611 to the other side of the recycling support 61, preventing the discharged heat from affecting the film.

[0063] The tube frame 64 includes a receiving body 641 rotatably mounted on a recycling support 61 and receiving racks 642 rotatably mounted at both ends of the receiving body 641. The film is wound onto the tube frame 64; specifically, a recycling tube is fitted onto the receiving rack 642, and the film is wound onto the recycling tube of the receiving rack 642. The receiving rack 642 is driven to rotate by a motor to complete the film recycling. The receiving body 641 is driven to rotate by a motor to switch the position of the receiving rack 642, allowing the film to be wound onto a new recycling tube.

[0064] Second embodiment: Cutting steps: The recycled material is fed between the first rollers 12. After passing through multiple sets of first rollers 12, the recycled material is rolled into a flat shape of a set thickness. The second roller 14 conveys the recycled material, which is then cut into several strips by the cutting disc 15. One end of the recycled strip is placed on the bracket 113. The bracket 113 moves so that the other end of the recycled strip is placed on the belt conveyor 111. The bracket 113 swings downward to completely place the recycled strip on the belt conveyor 111. The belt conveyor 111 conveys the recycled strip into the trough 173. The rotation of the cylinder 171 drives the recycled strip into the spray cylinder 22.

[0065] Weaving steps: The motor drives the power shaft 24 to rotate, which drives two sets of shaft blocks 241 to rotate eccentrically alternately. The shaft blocks 241 drive the rod frame 211 to move up and down through the block rod 242, so that the adjacent weaving rods 21 move back and forth alternately, which drives the adjacent new material thread to be stretched up and down alternately.

[0066] The spray nozzle 22 sprays the recycled material line through the adjacent new material line. The clamping mechanism 23 clamps the recycled material line. The motor drives the eccentric block 235 to rotate, and the eccentric block 235 pushes the clamping frame 232 closer to the mating frame 233. The clamping frame 232 pushes the mating frame 233 to swing. The limiting block 234 restricts the swing of the mating frame 233. The cutting block 237 cuts both ends of the new material line. The eccentric block 235 no longer pushes the clamping frame 232. The third elastic device 236 pushes the clamping frame 232 and the mating frame 233 to reset. The above steps are repeated continuously, and the recycled material line and the new material line are woven into a material net.

[0067] By controlling the frequency of the up-and-down reciprocating movement of the rod frame 211 driven by the control rod 242, the frequency of alternating up-and-down stretching of adjacent new material lines is controlled. By controlling the swing amplitude of the clamping mechanism 23, the distance between the recycling line and the new material line is controlled, so that the recycling line and the new material line are woven at a certain density, ensuring that the recycling line and the new material line are evenly distributed in a certain proportion in the material net.

[0068] Shaping and cutting steps: The first heating tube 33 heats the first rolling shaft 32 to a set temperature. The material mesh passes between the first rolling shafts 32, and the first rolling shafts 32 hot roll the overlapping position of the new material line and the recycling line. The first elastic device 36 pushes the swing plate 34 to contact the material mesh, and the cutting teeth 35 cut the material mesh to form a material edge, which covers the position of the mesh opening.

[0069] Processing steps: The mesh passes through the heating channel 41, and the gas is heated by the second heating tube 42. Part of the hot gas flows through the heating plate 43 and acts on the mesh. Another part of the hot gas flows through the second rolling mechanism 5 to keep it warm. After passing through the second rolling mechanism 5, another part of the hot gas enters the adjacent second heating tube 42 to be heated again. The remaining part of the hot gas continues to flow through the heating plate 43 and acts on the mesh.

[0070] When the mesh is moved in, the second rolling shaft 51 rolls the mesh, and the convex strip 52 folds and presses the mesh. During the movement of the mesh, the bending amplitude of the mesh gradually decreases, and the bending shape of the mesh transitions from sharp angles to curves. When the mesh is moved out, the second rolling shaft 51 rolls the mesh into a thin film.

[0071] Recycling steps: The film is wound around each recycling roller 62 and moves, and the cooler 63 absorbs the heat from the film and discharges it from the exhaust port 611. The motor drives the receiving rack 642 to rotate, and the film is wound onto the recycling cylinder on the receiving rack 642. The motor drives the receiving body 641 to rotate, and the film is wound onto the recycling cylinder on the new receiving rack 642.
