[0002] TPU film is a film made from TPU granules through special processes such as calendering, casting, film blowing, and coating. TPU film is a thermoplastic TPU elastomer. Due to its good elasticity, good physical properties, and good mechanical strength, it is widely used in processing methods such as injection, extrusion, calendering, and dissolving into solution-type resins. It is a plastic material frequently used by plastic processing industries. Its products cover the range of industrial applications and civilian necessities. In the process of TPU film production and processing, the prepared finished product needs to be pressurized and rolled up to facilitate the storage and transportation of the finished product.

[0029] Description of the working method of the present invention: The TPU three-in-one winder adopting this structure first realizes stable support by connecting the side plates 11 at the left and right ends of the base 12 respectively. The left and right ends of the main roller 21 and the tensioning roller group 22 are rotatably connected to the two groups of side plates 11 and remain parallel to each other. The tensioning roller group 22 includes a plurality of rollers. The fed film material 3 is wound back and forth between the plurality of rollers to maintain the tension of the film material 3. Since the winding of the film material 3 between the plurality of rollers belongs to the prior art, it is not necessary to elaborate on how to achieve it here. The film material 3 derived from the tensioning roller group 22 will be inserted between the main roller 21 and the winding roller 23 and then wound around the winding roller 23. In order to achieve winding and maintain the winding quality, on the one hand, the winding method should be changed by changing the distance between the winding roller 23 and the main roller 21, and on the other hand, the winding is achieved by driving the rotation of the winding roller 23 and the main roller 21.

[0030] In order to make the winding roller 23 abut against the main roller 21 along the y-axis direction, a displacement component 43 is provided. By starting the first cylinder 433, the first slide 432 is pulled to move along the y-axis direction on the first guide rail 431, and the winding roller 23 connected to the first slide 432 will be driven and abut against the main roller 21. However, since the winding roller 23 will gradually thicken in the process of continuously winding the film material 3, relying on the first cylinder 433 to keep the winding roller 23 abutting against the main roller 21 will result in failure to rewind, and the cylinder cannot achieve precise fine-tuning during pulling and pushing. Therefore, it is unrealistic to push the first slide 432 by the first cylinder 433 to allow the winding roller 23 thereon to be slowly pushed away during its gradual thickening. Therefore, a stepping component 44, a transmission shaft 45 and a servo motor 46 are added. The servo motor 46 A transmission shaft 45 is installed on the base 12 and drives the transmission shaft 45 which is rotatably connected to the two sets of side plates 11. The end of the transmission shaft 45 passes through the side plate 11 and is connected to the gear 451. When the gear 451 engages the first rack 444 and drives it to move along the y-axis, it drives the first slide 432 to perform precise fine-tuning, so as to achieve synchronous displacement as the film material 3 on the winding roller 23 gradually thickens and maintain contact with the main roller 21. Since there is air pressure in the first cylinder 433 itself, the first cylinder 433 and the first rack 444 are connected to the first slide 432 at the same time, which will cause the first rack 444 to drive the first slide 432 to be pulled in the opposite direction by the first cylinder 433 and unable to move. Therefore, when the servo motor 46 is working, the first cylinder 433 can be automatically depressurized as needed to make the first cylinder 433 fail and not work.

[0031] Since the winding roller 23 needs to be able to change rollers in order to improve production efficiency, the winding roller 23 itself cannot be fixed, but needs to be flexibly disassembled and driven to rotate. Therefore, the second slide 435 is driven by the second cylinder 436 on the first slide 432 to move along the x-axis direction on the second guide rail 434, and the rotating motor 42 on the second slide 435 is moved toward the winding roller 23, so that the gear shaft 421 is embedded in the tooth groove 231, and at the same time, the top seat 437 of the second slide 435 on the displacement member 43 on the side plate 11 on the other side is also driven to move toward the winding roller 23, and the top cone 438 is embedded in the top groove 232, so that the winding roller 23 is clamped from both ends, and the winding roller 23 can be driven to rotate around the x-axis when the rotating motor 42 is started.

[0032] Therefore, when winding the film material 3 on the winding roller 23, there are three winding forms: when used as a center winding, the driving motor 41 is not started, and the main roller 21 is kept in a driven state. The winding roller 23 first contacts the main roller 21 by pulling the first cylinder 433 in a clamped state, and then the first cylinder 433 is depressurized, and the rotating motor 42 is started to drive the winding roller 23 to rotate for active winding, and then the servo motor 46 is started to drive the first slide 432 to perform fine displacement adjustment to maintain the speed of thickening of the film material 3 on the winding roller 23, thereby maintaining winding; when used as a surface winding, the rotating motor 42 is not started, and the winding roller 23 is kept in a clamped driven state, and The first cylinder 433 is pulled to make the winding roller 23 abut against the main roller 21, and then the first cylinder 433 is depressurized, and the drive motor 41 is started to drive the main roller 21 to rotate and drive the winding roller 23 to perform driven winding, and then the servo motor 46 is started to drive the first slide 432 to perform fine displacement adjustment to maintain the speed of thickening of the film material 3 on the winding roller 23, thereby maintaining the winding; when used as an intermittent winding, the drive motor 41 is not started, and the winding roller 23 is in a clamped state, and the first slide 432 is driven by the first cylinder 433 or the servo motor 46 to displace and maintain a distance from the main roller 21, and the rotating motor 42 is started to drive the winding roller 23 to rotate for active winding, thereby maintaining the winding.

[0033] After winding is completed, the winding roller 23 needs to be replaced to improve production efficiency. Therefore, a guiding component 6 is set to guide the winding roller 23 to discharge the material, a roller changing component 5 is set to replace the empty winding roller 23, and a cutting component 7 is set to cut the film material 3.

[0034] First, in order to facilitate the unloading of the winding roller 23 after winding, a guide rail 61 is set, and a guide seat 62 is provided on the left and right ends of the winding roller 23, and the guide groove 621 on the guide seat 62 is embedded in the guide rail 61, so that the winding roller 23 can only move forward and backward along the y-axis direction along the guide rail 61 whether it is clamped or not. At the same time, a limiter 63 is set in the middle of the guide rail 61. The limiter 63 consists of a limit seat 631, a limit head 632 and a spring. A limit groove is provided above the limit seat 631, and one end of the limit head 632 can be rotatably connected to the limit groove, and the lower end of the other end is connected to the limit groove through a spring. Connected in the limit groove, in the absence of external force, the other end of the limit head 632 will remain in an upward state due to the force of the spring. Therefore, when the winding roller 23 moves from the winding material end 64 to the discharge direction end on the guide rail 61 and passes through the limiter 63, the other end of the limit head 632 can be pressed downward. After passing through the limiter 63, the upward-tilted other end of the limit head 632 will maintain a limiting abutment effect on the winding roller 23, ensuring that the winding roller 23 cannot re-enter the winding material end 64 from the discharge end 65, thereby preventing the winding roller 23 that has already discharged from the material from rolling back and affecting the normal winding of the empty winding roller 23.

[0035] In order to complete the roller changing operation, the roller changing assembly 5 is required to be able to clamp the winding roller 23 from the material discharging end 65 on the guide rail 61, and then move up, move horizontally, and then lower it to the work station at the winding material end 64 to clamp and perform the winding operation. Therefore, the fourth slide 52 is driven by the fourth cylinder 53 to move along the y-axis direction on the fourth guide rail 51, and the clamping member 55 is driven by the fifth cylinder 54 to move along the z-axis direction. In order to transfer the winding roller 23, a clamping groove 622 is set on the guide seat 62, and the clamping member 55 on the fourth slide 52 is driven by the fifth cylinder 54 to move the winding roller 23 to the z-axis direction. The U-shaped clamp 551 moves downward and is embedded in the clamping groove 622, and then the clamping head 552 is horizontally clamped at the lower end of the clamping groove 622 by the drive of the sixth cylinder 553. The enclosed closed frame 555 clamps the guide seat 62, so that the winding roller 23 can be clamped during the up and down and forward and backward movements of the y-axis and the z-axis. More preferably, two groups of sixth cylinders 553 and clamping heads 552 can be set on the lower end of the U-shaped clamp 551. The two groups of clamping heads 552 are abutted against each other under the drive of the sixth cylinder 553, and are enclosed together with the notch 554 to form a circular hoop that cooperates with the clamping groove 622, which can have a better clamping effect.

[0036] Before the winding roller 23 that has completed winding moves into the discharge end 65, the clamping member 55 grabs the empty winding roller 23 and moves it above the winding roller 23 that has completed winding. After the winding roller 23 that has completed winding is pushed into the discharge end 65 by the first cylinder 433 or the first rack 444, the film material 3 will also extend toward the discharge end 65 along with the winding roller 23 that has completed winding. At this time, the seventh cylinder 71 is started first to drive the rotating plate 73 to rotate on the rotating shaft. The lifting roller 74 at the end is raised and inserted between the winding roller 23 and the main roller 21, and abuts against the bottom of the film material 3. The fifth cylinder 54 is then driven to press the empty winding roller 23 on the clamping member 55 down onto the guide rail 61. At the same time, the film material 3 is pressed between the lifting roller 74 and the main roller 21. The film material 3 will fit on the empty winding roller 23. By starting the main roller 21, the film material 3 on the winding roller 23 is pressed. After the film 3 is cut off, the seventh cylinder 71 is started again to rotate the rotating plate 73 back to its original position. Therefore, the winding roller 23 that has completed winding can be discharged after the film 3 is cut off. Therefore, the second cylinder 436 is started to disengage the gear shaft 421 and the top cone 438 from the winding roller 23 that has completed winding, and move to the position of the empty winding roller 23 under the drive of the first cylinder 433. The second cylinder 436 is started again to embed the gear shaft 421 and the top cone 438 to complete the clamping of the empty winding roller 23, realize the winding of the empty winding roller 23, maintain the continuous operation of production, and have sufficient time for the workers to unload the winding roller 23 that has completed winding before the winding is completed, and place the empty winding roller 23 at the discharge end 65 for subsequent cyclic winding. Example 2

[0037] like Figure 8 , 14As shown, it also includes a compacting assembly 8, the compacting assembly 8 includes a compacting member 81 and a compacting roller 82; the compacting member 81 includes a fifth guide rail 811, a fifth slide 812, an eighth cylinder 813, a sixth guide rail 814, a sixth slide 815 and a ninth cylinder 816, the fifth guide rail 811 and the eighth cylinder 813 are both arranged on a group of side plates 11, the bottom of the fifth slide 812 is slidably connected to the fifth guide rail 811, the output end of the eighth cylinder 813 is connected to the fifth slide 812, and the fifth slide 812 is displaced along the z-axis direction on the fifth guide rail 811 under the drive of the eighth cylinder 813; the sixth guide rail 814, the sixth slide 815 and the ninth cylinder 816 The rail 814 and the ninth cylinder 816 are both arranged on the fifth slide 812, the bottom of the sixth slide 815 is slidably connected to the sixth guide rail 814, the output end of the ninth cylinder 816 is connected to the sixth slide 815, and the sixth slide 815 is displaced along the y-axis direction on the sixth guide rail 814 under the drive of the ninth cylinder 816; the compacting component 81 includes two groups and is symmetrically arranged on two groups of side plates 11 with the base 12 as the center of symmetry. The left and right ends of the compacting roller 82 are rotatably connected to the two groups of sixth slides 815, and the outer wall of the compacting roller 82 can be abutted against the film material 3 on the outer wall of the winding roller 23.

[0038] Since the film material 3 may inevitably contain air when it is rolled up on the winding roller 23, if the film material 3 is allowed to contain air, on the one hand, the volume of the final roll will be too large, and on the other hand, the film material 3 will be affected by excessive contact with air, so a compacting component 8 is added, which is arranged at the other end of the winding roller 23 opposite to the main roller 21, and the fifth slide 812 is driven by the eighth cylinder 813 to move along the z-axis direction on the fifth guide rail 811, and the ninth cylinder 816 drives the sixth slide 815 on the sixth guide rail 816. 14 is displaced along the y-axis direction, thereby making the compacting roller 82 abut against the film material 3 on the winding roller 23. During the winding process of the film material 3, it will definitely be squeezed by the compacting roller 82, thereby discharging the air along the winding direction to avoid the air being wrapped inside. When the winding roller 23 completes winding and is about to discharge the material, the eighth cylinder 813 and the ninth cylinder 816 are started to move the compacting roller 82 downward to avoid obstructing the discharge of the winding roller 23, and after replacing the empty winding roller 23, the compacting roller 82 is again abutted against the empty winding roller 23. Example 3

[0039] like Figure 5 , 6, 10, and 13, it also includes a buffer component 9, which includes a buffer member 91, a buffer motor 92, and a buffer roller 93; the buffer member 91 includes a seventh guide rail 911, a seventh slide 912, a gear 451 shaft and a second rack 914, the seventh guide rail 911 and the second rack 914 are both arranged on a group of side plates 11, the bottom of the seventh slide 912 is slidably connected to the seventh guide rail 911, the gear 451 shaft can be rotatably connected to the seventh slide 912 and meshed with the second rack 914; the buffer member 91 includes two groups and is symmetrically arranged on the two groups of side plates 11 with the base 12 as the symmetry center, the left and right ends of the buffer roller 93 are rotatably connected to the two groups of gear 451 shafts; the buffer motor 92 is arranged on one of the groups of the seventh slide 912 and drives the gear 451 shaft, and the buffer roller 93 is displaced along the z-axis direction under the drive of the buffer motor 92, extends into the tensioning roller group 22 and abuts on the film material 3.

[0040] When the winding roller 23 is replaced, the film material 3 cannot be wound during the period before the empty winding roller 23 is replaced, but the film material 3 fed from one end of the tensioning roller group 22 will maintain the feeding speed due to the effect of inertia. If no operation is performed to interfere at this time, the film material 3 before entering the tensioning roller group 22 will sag due to the inertia force, which may cause contamination due to contact with other places, or may be reversely wound due to the inertial throwing force. This section of film material 3 will affect its quality in the subsequent winding. Therefore, in order to avoid this situation, a buffer component 9 is provided. By A buffer roller 93 is added to press the film material 3 from top to bottom. When the winding roller 23 changes rollers and cannot be wound, the buffer roller 93 starts the buffer motor 92 to drive the gear 451 shaft to move downward along the direction of the second rack 914, so that the buffer roller 93 maintains the original winding speed for pressing down, so that the subsequent film material 3 fed enters the buffer space under the buffer roller 93, maintaining a certain tension on the fed film material 3 to avoid contamination of the film material 3 due to inertial sagging or reverse winding. When the winding roller 23 completes the roller change, the winding is accelerated, and at the same time, the buffer roller 93 is lifted to gradually release the accumulated film material 3 until normal production is resumed.

[0041] The beneficial effect of the present invention is that the film material 3 is wound around several tension rollers on the tension roller group 22, and finally passes between the main roller 21 and the winding roller 23 and is wound around the winding roller 23. The winding roller 23 / main roller 21 is started in different winding forms, so that the film material 3 is wound on the winding roller 23. At the same time, the servo motor 46 drives the winding roller 23 to move in the y-axis direction during the continuous winding and thickening process until the winding is completed and the material is discharged. The empty winding roller 23 is pressed downwards between the winding roller 23 and the main roller 21 that have completed the material collection under the drive of the roller changing assembly 5, and the empty winding roller 23 is The film material 3 is wound on the winding roller 23 and the film material 3 is cut with the cutter 76 at the same time, so that the worker can unload the wound TPU film without delaying the normal winding work, thereby improving work efficiency. In order to prevent the film material 3 from being encapsulated by air during the winding process, the excess air is discharged through the compacting component 8. In order to prevent the feeding film material 3 from sagging or reverse winding due to inertia during the roller changing process, the film material 3 is pre-stored through the buffer component 9, and the winding is accelerated after the roller changing is completed. At the same time, the upper buffer component 9 gradually releases the accumulated film material 3 until normal production is resumed.
