Description

Technical Field

[0001] This utility model relates to the field of recycled rubber strapping technology, specifically to a recycled rubber strapping cutting and strapping device. Background Technology

[0002] Waste tires contain a variety of recyclable materials, such as rubber, steel wire, and fibers. Recycling and reprocessing these waste tires not only reduces environmental pollution but also achieves resource recycling, effectively lowering the demand for new resources. One of the core steps in realizing tire resource utilization is processing waste tires into recycled rubber belts through a series of complex processes including crushing, desulfurization, and refining.

[0003] After the recycled rubber belt is prepared, because the finished product is a continuous long strip, it needs to be cut into segments of a predetermined length and then packaged in plastic to meet the needs of subsequent transportation, storage and use by downstream customers. Therefore, cutting and plastic packaging are key processes before the recycled rubber belt leaves the factory.

[0004] However, in the current recycled rubber tape production industry, the overall automation level of the process of cutting and sealing recycled rubber tape is low. There is a lack of seamless automation between the cutting and sealing processes. The core operation still relies on semi-automatic equipment and manual labor. The cut recycled rubber tape is stacked manually and then sent to the packaging equipment for sealing. This production process requires a lot of manpower, which increases the production cost of enterprises. Moreover, manual operation is inefficient, labor-intensive, and even a slight oversight may lead to uneven stacking, affecting the subsequent packaging quality and making it difficult to meet the demand for high-efficiency production. Utility Model Content

[0005] In view of this, it is necessary to provide a device for cutting and packaging recycled rubber strips to solve the technical problems of low efficiency and high labor costs associated with manual operation in the prior art.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A reclaimed rubber strip cutting and packaging device includes a cutting mechanism, a conveying mechanism, a stacking mechanism, and a sealing mechanism. The cutting mechanism is located at the input end of the conveying mechanism, the stacking mechanism is located directly above the conveying mechanism, and the sealing mechanism is located at the output end of the conveying mechanism. The cutting mechanism can cut the reclaimed rubber strip into sheet rubber of a predetermined length and arrange the sheet rubber sequentially into the conveying mechanism. The stacking mechanism can stack the sheet rubber sequentially on the conveying mechanism. The conveying mechanism can transport the stacked sheet rubber to the sealing mechanism for sealing.

[0008] Preferably, the cutting mechanism includes a frame, a main conveyor roller, an auxiliary roller, a first drive motor, and a cutter. Symmetrical uprights are arranged on opposite sides of the upper surface of the frame. Near the end of the frame facing the conveyor mechanism, symmetrical grooves are formed on the opposite sidewalls of the two uprights. These grooves are vertically formed, and a bearing seat is provided in each groove. The two ends of the auxiliary roller are rotatably connected to the two bearing seats, which can slide freely up and down along the grooves. The main conveyor roller is rotatably positioned laterally below the auxiliary roller, parallel to it, with its surface protruding from or flush with the upper surface of the frame. The first drive motor is located on the outside of the frame and connected to the shaft of the main conveyor roller. Rotatable lead screws are also vertically arranged in each of the two grooves, and the bearing seats in the two grooves are respectively connected to the two... Two lead screws are connected by a threaded connection. Rotating the two lead screws adjusts the distance between the auxiliary roller and the main conveyor roller. Two first telescopic cylinders are also installed on the two uprights. The two first telescopic cylinders are located on the side of the auxiliary roller facing the conveying mechanism. The two first telescopic cylinders are at the same height, and their telescopic arms are vertically set downwards. The two ends of the cutter are fixed to the ends of the telescopic arms of the two first telescopic cylinders, and the blade is vertically facing the upper end of the frame downwards. The main conveyor roller and the auxiliary roller can clamp the recycled rubber strip to be cut. The first drive motor drives the main conveyor roller to rotate, which can transport the recycled rubber strip to be cut towards the cutter. The two first telescopic cylinders move synchronously to drive the cutter to move up and down reciprocally, cutting the recycled rubber strip to be cut into sheet rubber of predetermined length.

[0009] Preferably, the frame is symmetrically provided with roller frames on both sides facing the end of the conveying mechanism. The roller frames extend toward the conveying mechanism and are inclined downwards. Several freely rotatable idlers are horizontally supported between the two roller frames. The idlers are spaced apart along the inclined extension direction of the roller frames to form a slope. The input end of the conveying mechanism is set close to the roller frames, and the height of the idler at the highest point is lower than the upper end face of the frame, while the height of the idler at the lowest point is higher than the input end of the conveying mechanism, so that the sheet rubber cut by the cutter can be discharged into the conveying mechanism along the idlers.

[0010] Preferably, the conveying mechanism includes a first belt conveyor, a second belt conveyor, and a third belt conveyor arranged in parallel end to end. The input end of the first belt conveyor is set close to the roller frame to receive the cut sheet rubber and convey the received sheet rubber to the second belt conveyor. The palletizing mechanism is located directly above the second belt conveyor, and the sealing mechanism is located at the output end of the third belt conveyor. The palletizing mechanism includes a guide rail, a moving frame, a tying frame, a discharge baffle, a second drive motor, a second telescopic cylinder, and a third telescopic cylinder. The guide rail is erected parallel to the second belt conveyor and the third belt conveyor. Above the conveyor, a matching movable frame is mounted on a guide rail. A lead screw, threaded to the movable frame, is installed inside the guide rail, extending along the length of the guide rail. A second drive motor is mounted at one end of the guide rail and is shaft-connected to the lead screw. The telescopic arm of the second telescopic cylinder is vertically mounted downwards on the movable frame. A binding frame is parallel to the telescopic arm of the second telescopic cylinder. Several vertical binding heads for binding sheet rubber are spaced apart at the lower end of the binding frame. The second telescopic cylinder drives the binding frame to move up and down, binding the sheet rubber conveyed on the second belt conveyor through the binding heads. The second drive motor drives the moving frame to reciprocate along the guide rail via a lead screw, thereby moving the binding frame and the bound sheet rubber towards the conveying surface of the third belt conveyor. The unloading baffle is arranged parallel to the binding frame directly below it, and has several first through holes that match the binding head. At least two third telescopic cylinders are vertically arranged on the upper end of the binding frame, located on either side of the second telescopic cylinders. The telescopic arms of the third telescopic cylinders pass through the binding frame and are fixedly connected to the unloading baffle. The third telescopic cylinders drive the unloading baffle to move up and down. When the binding head is binding the sheet rubber, the third telescopic cylinders drive the unloading. The baffle rises, allowing the binding head to pass through the first through hole. When the bound sheet rubber is moved to the conveying surface of the third belt conveyor, the third telescopic cylinder drives the unloading baffle to descend. The unloading baffle squeezes the bound sheet rubber, causing it to detach from the binding head and fall onto the conveying surface of the third belt conveyor. By repeating the above binding, moving, and detaching actions, the sheet rubber conveyed on the second belt conveyor can be stacked on the third belt conveyor. The third belt conveyor can transport the stacked sheet rubber to the sealing mechanism for sealing.

[0011] Preferably, the upper end face of the frame is also provided with a wheel-type distance measuring instrument for measuring the conveying length of the recycled rubber belt, and the wheel-type distance measuring instrument is located on the side of the auxiliary roller away from the conveying mechanism.

[0012] Preferably, the second belt conveyor includes a support frame, two drive rollers, several auxiliary conveyor belts, and a third drive motor. The two drive rollers are rotatably and laterally arranged at both ends of the support frame and are parallel to each other. The several auxiliary conveyor belts are annularly sleeved on the two drive rollers and spaced apart along the axial direction of the drive rollers. The third drive motor is located on the outside of the support frame and connected to the shaft of one of the drive rollers to drive the auxiliary conveyor belts to operate synchronously. A support plate is also arranged parallel to the support frame. The support plate is located between the two drive rollers and below the upward conveying surface of the auxiliary conveyor belts, facing the tie-up frame. The support plate has several vertically opened second through holes corresponding to the tie heads. The second through holes are located between two adjacent auxiliary conveyor belts and facing the tie heads, so that the tie heads can pass through.

[0013] Preferably, a positioning baffle is provided on the side of the pallet facing the output direction of the second belt conveyor. There are at least two positioning baffles, which are respectively arranged between two adjacent secondary conveyor belts and extend upwards from the upper conveying surface of the secondary conveyor belt. The extension height corresponds to the thickness of the sheet rubber, so as to stop and position the sheet rubber conveyed on the secondary conveyor belt.

[0014] Preferably, the second belt conveyor has symmetrically arranged lateral positioning mechanisms on both sides of its support. Each lateral positioning mechanism includes a fixed frame, a telescopic drive, and a side baffle. The fixed frames are respectively installed on both sides of the support, and sliding sleeves are fixedly installed at both ends of the fixed frames. The sliding sleeves on the two fixed frames face each other. The two side baffles are respectively installed inside the two fixed frames, with both ends of the two side baffles facing the two drive rollers and perpendicular to the axial direction of the drive rollers, and higher than the upward conveying surface of the secondary conveyor belt. Sliding rods matching the sliding sleeves are arranged laterally on the back of the two side baffles. The sliding rods on the two side baffles are respectively inserted into the sliding sleeves of the two fixed frames and can slide freely along the sliding sleeves. The two telescopic drives are respectively installed outside the two fixed frames and located between the two sliding sleeves. The telescopic arms of the two telescopic drives pass through the two fixed frames and are respectively connected to the two side baffles. The two telescopic drives can synchronously drive the two side baffles to move in opposite directions to center and position the sheet rubber conveyed on the secondary conveyor belt.

[0015] Preferably, the sealing mechanism includes a laminating machine and a thermoforming machine. The input end of the laminating machine is directly opposite the output end of the third belt conveyor, and the input end of the thermoforming machine is directly opposite the output end of the laminating machine. The third belt conveyor transports the stacked sheet rubber to the laminating machine. The laminating machine laminates the stacked sheet rubber and transports the laminated sheet rubber to the thermoforming machine for thermoforming sealing.

[0016] Preferably, a weighing instrument is provided at the lower end of the first belt conveyor to weigh the sheet rubber entering the first belt conveyor.

[0017] As can be seen from the above technical solution, the recycled rubber strip cutting and packaging device provided in this application includes a cutting mechanism, a conveying mechanism, a stacking mechanism, and a sealing mechanism. The cutting mechanism is located at the input end of the conveying mechanism, the stacking mechanism is located directly above the conveying mechanism, and the sealing mechanism is located at the output end of the conveying mechanism. The cutting mechanism can cut the recycled rubber strip into sheet rubber of a predetermined length and arrange the sheet rubber into the conveying mechanism in sequence. The stacking mechanism can stack the sheet rubber into layers on the conveying mechanism in sequence. The conveying mechanism can transport the stacked sheet rubber to the sealing mechanism for sealing. The beneficial effect is that by setting the stacking mechanism and the conveying mechanism to cooperate, the stacking mechanism can stack the cut sheet rubber into layers on the conveying mechanism in sequence, so that the cutting and sealing packaging processes are effectively connected, avoiding the trouble of manual stacking, saving time and labor, improving production efficiency, and reducing the production cost of enterprises.

[0031] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0032] Please refer to Figure 1 This utility model provides a device for dividing and packaging recycled rubber strips, including a dividing and cutting mechanism 10, a conveying mechanism 20, a stacking mechanism 30, and a sealing mechanism 40. The dividing and cutting mechanism 10 is located at the input end of the conveying mechanism 20, the stacking mechanism 30 is located directly above the conveying mechanism 20, and the sealing mechanism 40 is located at the output end of the conveying mechanism 20. The dividing and cutting mechanism 10 can cut the recycled rubber strip into sheet rubber of a predetermined length and arrange the sheet rubber in sequence into the conveying mechanism 20. The stacking mechanism 30 can stack the sheet rubber that has entered the conveying mechanism 20 in layers on the conveying mechanism 20. The conveying mechanism 20 can transport the stacked sheet rubber to the sealing mechanism 40 for sealing.

[0033] Please refer to Figures 1 to 3Specifically, the cutting and slitting mechanism 10 includes a frame 11, a main conveying roller 12, a secondary roller 13, a first drive motor 14, and a cutter 15. The upper surface of the frame 11 is a conveying surface. symmetrical uprights 16 are arranged on opposite sides of the upper surface of the frame 11. The uprights 16 are located near the end of the frame 11 facing the conveying mechanism 20, forming a conveying channel between the two uprights 16. Slide grooves 161 are symmetrically opened on the opposite sidewalls of the two uprights 16. The slide grooves 161 are vertically opened, and bearing seats 162 are respectively arranged in the two slide grooves 161. The two ends of the secondary roller 13 are rotatably connected to the two bearing seats 162 respectively. The bearing seats 162 can slide freely up and down along the slide grooves 161. The main conveyor roller 12 is rotatably and laterally mounted on the conveying surface of the frame 11. The main conveyor roller 12 is horizontally positioned and located directly below the auxiliary roller 13. The main conveyor roller 12 and the auxiliary roller 13 are parallel, and the roller surface of the main conveyor roller 12 protrudes from or is flush with the upper end face of the frame 11. The first drive motor 14 is located on the outside of the frame 11 and connected to the shaft of the main conveyor roller 12. Rotatable lead screws 163 are vertically mounted in two slide grooves 161, and the shaft seats 162 in the two slide grooves 161 are threadedly connected to the two lead screws 163. A rotatable handle 164 is mounted on the top of the upright frame 16, and the handle 164 is coaxially connected to the lead screws 163. Handle 164 can rotate two lead screws 163 respectively, which drive two shaft seats 162 to move up and down along the slide groove 161, thereby adjusting the distance between the auxiliary roller 13 and the main conveyor roller 12. Two first telescopic cylinders 18 are also installed on the two uprights 16, respectively. The two first telescopic cylinders 18 are located on the side of the auxiliary roller 13 facing the conveyor mechanism 20, and are at the same height, with their telescopic arms pointing downwards vertically. The cutter 15 is horizontally arranged between the two uprights 16, with both ends of the cutter 15 fixed to the ends of the telescopic arms of the two first telescopic cylinders 18, and the blade pointing downwards vertically towards the upper surface of the frame 11. A cutting groove matching the cutter 15 is opened laterally on the end face. The cutting groove is directly opposite the cutter 15. The main conveying roller 12 and the auxiliary roller 13 can clamp the recycled rubber strip to be cut. The first drive motor 14 drives the main conveying roller 12 to rotate, which can transport the recycled rubber strip to be cut along the upper end face of the frame 11 towards the cutter 15. The two first telescopic cylinders 18 are powered by an externally installed air compressor and controlled by a control switch, and can perform synchronous telescopic movement to drive the cutter 15 to move up and down reciprocally. When the cutter 15 moves downward, it can cut into the cutting groove and cut the recycled rubber strip to be cut on the upper end face of the frame 11 into sheet rubber of a predetermined length.

[0034] Please continue reading. Figure 2 and Figure 3On both sides of the frame 11 facing the end of the conveying mechanism 20, roller frames 17 are symmetrically arranged. The roller frames 17 extend towards the conveying mechanism 20 and are inclined downwards. Several freely rotatable idlers 171 are horizontally mounted between the two roller frames 17. The idlers 171 are spaced apart along the inclined extension direction of the roller frames 17 to form a slope. The input end of the conveying mechanism 20 is set close to the roller frames 17. The height of the idler 171 at the highest point is lower than the upper end face of the frame 11, and the height of the idler 171 at the lowest point is higher than the input end of the conveying mechanism 20. The cut sheet rubber falls onto the idler 171 under the action of gravity and can be discharged into the conveying mechanism 20 by itself along the idler 171.

[0035] Please refer to Figure 1 and Figure 4 The conveying mechanism 20 includes a first belt conveyor 21, a second belt conveyor 22, and a third belt conveyor 23 arranged in parallel and connected end to end. The input end of the first belt conveyor 21 is set close to the lowest idler roller 171 of the roller frame 17, which is used to receive the cut sheet rubber and convey the received sheet rubber to the second belt conveyor 22. The palletizing mechanism 30 is set directly above the second belt conveyor 22, and the sealing mechanism 40 is set at the output end of the third belt conveyor 23. The palletizing mechanism 30 can move up and down to grab the sheet rubber that has entered the second belt conveyor 22, and can move back and forth towards the third belt conveyor 23 to stack the grabbed sheet rubber on the third belt conveyor 23. The third belt conveyor 23 can transport the stacked sheet rubber to the sealing mechanism 40, so that the sealing mechanism 40 can seal the stacked sheet rubber.

[0036] For details, please refer to Figures 4 to 8The palletizing mechanism 30 includes a guide rail 31, a movable frame 32, a stacking frame 33, a second drive motor 35, a second telescopic cylinder 36, a third telescopic cylinder 37, and a discharge baffle 34 for extruding sheet rubber. The guide rail 31 is mounted parallel to the second belt conveyor 22 and the third belt conveyor 23 via a mounting frame. A matching movable frame 32 is mounted on the guide rail 31. A lead screw threaded to the movable frame 32 is installed inside the guide rail 31, extending along the length of the guide rail 31. The second drive motor 35 is mounted on the guide rail 31. One end of the first telescopic cylinder 36 is connected to the lead screw via a shaft, which drives the lead screw to rotate in the forward or reverse direction. This drives the moving frame 32 to reciprocate along the guide rail 31. The telescopic arm of the second telescopic cylinder 36 is vertically fixed downward on the moving frame 32. The binding frame 33 is a rectangular frame, which is parallel to the telescopic arm of the second telescopic cylinder 36 and faces the conveying surface of the second belt conveyor 22 or the third belt conveyor 23. The second telescopic cylinder 36 is used to drive the binding frame 33 to move up and down. The moving frame 32 can be driven by the second telescopic cylinder 36. The movable grabbing frame 33 reciprocates between the second belt conveyor 22 and the third belt conveyor 23. Several grabbing heads 38 are vertically spaced at the lower end of the grabbing frame 33. Each grabbing head 38 has a rod-like structure with a pointed lower end, used to grab sheet rubber conveyed on the second belt conveyor 22. The unloading baffle 34 is arranged parallel to the grabbing frame 33 directly below it. Several first through holes 39, matching the grabbing heads 38, are opened on the unloading baffle 34, with the grabbing heads 38 correspondingly passing through each first through hole 39. At least two third telescopic cylinders 37 are used. The third telescopic cylinder 37 is vertically mounted on the upper end of the binding frame 33 and located on both sides of the second telescopic cylinder 36. The telescopic arm of the third telescopic cylinder 37 passes through the binding frame 33 and is fixedly connected to the unloading baffle 34. The third telescopic cylinder 37 drives the unloading baffle 34 to move up and down. When the unloading baffle 34 is in the raised state, the tip of the binding head 38 can pass through the first through hole 39. When the unloading baffle 34 is in the lowered state, the tip of the binding head 38 can retract into the first through hole 39. When the unloading baffle 34 descends, it squeezes the sheet rubber attached to the binding head 38, causing it to detach from the binding head 38. In this embodiment, both the second telescopic cylinder 36 and the third telescopic cylinder 37 are powered by an externally installed air compressor and controlled by a control switch.

[0037] Please refer to Figure 4 and Figure 9The second belt conveyor 22 includes a support 221, two drive rollers 222, several secondary conveyor belts 223, and a third drive motor 224. The two drive rollers 222 are rotatably and laterally arranged at both ends of the support 221 and are parallel to each other. The secondary conveyor belts 223 are annularly sleeved on the two drive rollers 222 and spaced apart along the axial direction of the drive rollers 222. The third drive motor 224 is located outside the support 221 and is connected to the shaft of one of the drive rollers 222 to drive the secondary conveyor belts 223 to operate synchronously. The secondary conveyor belts 223 are used to convey sheet rubber. The binding frame 33 is located directly above each secondary conveyor belt 223, and the binding head 38 is directly opposite two adjacent secondary conveyor belts 223. In the gap between the two transmission rollers 222, a support plate 225 is also arranged parallel to the bracket 221. The support plate 225 is arranged between the two transmission rollers 222 and below the upward conveying surface of the secondary conveyor belt 223, and directly opposite the binding frame 33. The support plate 225 has several second through holes 226 vertically opened on it, corresponding to the binding head 38. The second through holes 226 are located between the gaps of two adjacent secondary conveyor belts 223 and are directly opposite the binding head 38. When the binding head 38 binds the sheet rubber conveyed on the secondary conveyor belt 223, the support plate 225 can provide support for each secondary conveyor belt 223, and the second through holes 226 on the support plate 225 can be used for the binding head 38 to pass through, so that the binding head 38 can be smoothly bound into the sheet rubber.

[0038] When the device is running, the initial position of the binding frame 33 is directly above the second belt conveyor 22, and the unloading baffle 34 is in the raised state. When the second belt conveyor 22 transports the sheet rubber to directly below the binding frame 33, it pauses. At this time, the second telescopic cylinder 36 drives the binding frame 33 to descend, so that the binding head 38 is inserted into the sheet rubber being transported on the second belt conveyor 22. The second telescopic cylinder 36 then drives the binding frame 33 to rise. Since the binding head 38 forms a tight bond with the sheet rubber after being inserted, the binding frame 33 can lift the bound sheet rubber upwards synchronously when it rises. After the binding frame 33 rises, the second drive motor... 35 drives the moving frame 32 to move towards the third belt conveyor 23. When the binding frame 33 is moved by the moving frame 32 to directly above the conveying surface of the third belt conveyor 23, the second telescopic cylinder 36 drives the binding frame 33 to descend. After the binding frame 33 descends to a predetermined height, the third telescopic cylinder 37 drives the unloading baffle 34 to descend. The unloading baffle 34 squeezes the sheet rubber bound on the binding head 38, causing it to detach from the binding head 38 and fall onto the conveying surface of the third belt conveyor 23. By repeating the above binding, moving and detaching actions, the sheet rubber conveyed on the second belt conveyor 22 can be stacked layer by layer on the third belt conveyor 23.

[0039] Please refer to Figure 6 and Figure 9Furthermore, since the sheet rubber may shift during cutting and conveying, the edges of the sheet rubber layers may not be effectively aligned after being stacked on the third belt conveyor 23. To reduce the alignment deviation, a positioning baffle 227 is provided on the side of the pallet 225 facing the output direction of the second belt conveyor 22. There are at least two positioning baffles 227, which are respectively set between two adjacent secondary conveyor belts 223 and extend upward from the gap between the two adjacent secondary conveyor belts 223 onto the upper conveying surface of the secondary conveyor belt 223. The extension height corresponds to the thickness of the sheet rubber. The positioning baffles 227 are arranged laterally on the upper conveying surface of the secondary conveyor belt 223, and their arrangement direction is perpendicular to the conveying direction of the secondary conveyor belt 223. When the second belt conveyor 22 conveys the sheet rubber to the positioning baffle 227, the positioning baffle 227 can stop and position the end of the sheet rubber to keep the end of the sheet rubber upright.

[0040] Please continue reading. Figure 9 and Figure 10Lateral positioning mechanisms 50 are symmetrically arranged on both sides of the support 221 of the second belt conveyor 22. Each lateral positioning mechanism 50 includes a fixed frame 51, a telescopic drive 52, and a side baffle 53. The fixed frames 51 are respectively installed on both sides of the support 221, and sliding sleeves 54 are fixedly installed at both ends of the fixed frames 51. The sliding sleeves 54 on the two fixed frames 51 face each other. The two side baffles 53 are respectively arranged on the opposite inner sides of the two fixed frames 51 and are parallel to each other. The two ends of the two side baffles 53 face each other. The transmission roller 222 is oriented in the direction of the transmission roller 222 and perpendicular to the axial direction of the transmission roller 222, and higher than the upward conveying surface of the auxiliary conveyor belt 223. On the back of each of the two side baffles 53, a sliding rod 55 matching the sliding sleeve 54 is arranged laterally. The sliding rods 55 on the two side baffles 53 are respectively inserted into the sliding sleeves 54 of the two fixed frames 51 and can slide freely along the sliding sleeves 54. Two telescopic drives 52 are electromagnetic telescopic devices or electric push rods, respectively located on the outside of the two fixed frames 51 and between the two sliding sleeves 54. The telescopic arms of the telescopic drive 52 pass through two fixed frames 51 and are respectively connected to two side baffles 53. The two telescopic drives 52 can synchronously drive the two side baffles 53 to move in opposite directions. Before the second belt conveyor 22 conveys the sheet rubber, the two side baffles 53 are in a state of being far apart from each other. When the sheet rubber conveyed on the second belt conveyor 22 contacts the positioning baffle 227, the second belt conveyor 22 is in a paused state. At this time, the two telescopic drives 52 synchronously drive the two side baffles 53 to move in opposite directions, utilizing... The sheet rubber conveyed on the second belt conveyor 22 is pushed in opposite directions by two side baffles 53, so that the sheet rubber is centered on the second belt conveyor 22. In this way, it can be ensured that each sheet rubber is centered and upright on the second belt conveyor 22 before being tied by the tie head 38. After the sheet rubber is stacked on the third belt conveyor 23, the edge alignment deviation of each layer of sheet rubber can be reduced, ensuring the regularity of the stacked sheet rubber, so as to facilitate the sealing mechanism 40 to seal it.

[0041] In this embodiment, position sensors are respectively installed on the two positioning baffles 227. When the position sensors on both positioning baffles 227 come into contact with the sheet rubber, the second belt conveyor 22 stops. In addition, after the two side baffles 53 approach each other, the distance between them is the same as the width of the conveyed sheet rubber to ensure that the sheet rubber is not squeezed and deformed.

[0042] Please refer to Figure 1 , Figure 11 and Figure 12The sealing mechanism 40 includes a laminating machine 41 and a thermoforming machine 42. The laminating machine 41 includes two conveyor belts 411 connected end to end, a thermoforming film release frame 412, a hot melt knife 413, and a pressing mechanism 414. Both conveyor belts 411 are belt conveyors, arranged parallel to each other on the thermoforming film release frame 412. The hot melt knife 413 is laterally positioned between the two conveyor belts 411 and is lower than the conveying surfaces of the two conveyor belts 411. The pressing mechanism 414 is laterally positioned directly above the hot melt knife 413. An upward thermoforming film release roller 415 and a downward thermoforming film release roller 416 are laterally arranged on the thermoforming film release frame 412. The upward thermoforming film release roller 415 is located above the pressing mechanism 414, and the downward thermoforming film release roller 416 is located below the hot melt knife 413. The ascending thermoplastic film release roller 415 and the descending thermoplastic film release roller 416 are parallel to each other and aligned at their ends. The input end of the first conveyor belt 411 faces the output end of the third belt conveyor 23, and the output end of the tail conveyor belt 411 faces the input end of the thermoplastic machine 42. A first guide roller 417 is laterally arranged on the side of the pressing mechanism 414 facing the third belt conveyor 23, and the first guide roller 417 is located directly above the conveyor belt 411. A second guide roller 418 is laterally arranged on the side of the hot melt knife 413 facing the third belt conveyor 23, and the second guide roller 418 is located below the conveyor belt 411. The thermoplastic film released by the ascending thermoplastic film release roller 415 is guided into the conveying mechanism 20 by the first guide roller 417, and the thermoplastic film released by the descending thermoplastic film release roller 416... The film is guided into the conveying mechanism 20 by the second guide roller 418. The third belt conveyor 23 conveys the stacked sheet rubber into the first end conveyor belt 411. The first end conveyor belt 411 conveys the stacked sheet rubber towards the tail end conveyor belt 411. When the stacked sheet rubber is conveyed past the first guide roller 417 and the second guide roller 418, the thermoplastic film released by the downward thermoplastic film release roller 416 will be laid on the bottom of the stacked sheet rubber, and the thermoplastic film released by the upward thermoplastic film release roller 415 will be laid on the top surface of the stacked sheet rubber. The pressing mechanism 414 includes a pressing arm 4141 and a fourth telescopic cylinder 4142. The fourth telescopic cylinder 4142 is longitudinally mounted on the thermoplastic film release frame 412, and the pressing arm 4141 is transversely arranged with the fourth telescopic cylinder 4142. The lower end of the telescopic cylinder 4142 is driven by the fourth telescopic cylinder 4142 to move up and down. When the stacked sheet rubber and thermoplastic film are conveyed through the hot melt knife 413, the fourth telescopic cylinder 4142 drives the pressure arm 4141 to descend, pressing the thermoplastic film released by the upward thermoplastic film release roller 415 and the downward thermoplastic film release roller 416 together onto the hot melt knife 413. The hot melt knife 413 melts and binds them together, so that the thermoplastic film can wrap the stacked sheet rubber. Then, it is conveyed to the thermoplastic machine 42 by the tail conveyor belt 411. The thermoplastic machine 42 is a heat shrink film packaging machine. After the wrapped sheet rubber is sent into the thermoplastic machine 42, the thermoplastic film wrapped on its surface can be heat-shrink sealed and formed by the thermoplastic machine 42.
