Description

Technical Field

[0001] This invention relates to the field of take-up roller technology, and more particularly to a take-up roller for a water-washable heat transfer film. Background Technology

[0002] In the printing and packaging industry, heat transfer film is increasingly widely used as an important graphic transfer medium. With the market's ever-increasing demands for heat transfer film quality, especially regarding washability, washable heat transfer film winding rollers have emerged. The history of heat transfer film can be traced back to the last century. At that time, with the rise of the plastics industry, the demand for graphic decoration on the surface of plastic products grew rapidly. Traditional methods such as screen printing and pad printing could hardly meet the increasingly diverse and high-quality decorative needs. Heat transfer technology gradually emerged due to its advantages of simplicity, speed, no pollution, and good adhesion. Heat transfer film, as a key consumable in heat transfer technology, began to come into focus.

[0003] Traditional water-resistant heat transfer film take-up rollers present several problems that urgently need to be addressed. Firstly, the traditional method of securing the film relies on manual operation, requiring workers to manually press one end of the film, roll it one full turn, and then release it. This is cumbersome and inefficient; improper operation not only necessitates repeated operations but also risks hand injuries. Secondly, the fixed diameter of traditional take-up rollers makes it difficult to adapt to changes in film roll diameter at different stages of winding, leading to uneven film tension, wrinkles, and loosening during winding, severely impacting winding quality and film flatness. Furthermore, after winding, the lack of effective separation measures results in the wound film roll adhering tightly to the roller, making quick separation difficult and time-consuming. This significantly limits production efficiency and cost control, failing to meet the demands of modern industrial production for efficient and precise winding, and necessitates improvement. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems mentioned in the background section.

[0005] The present invention adopts the following technical solution: a take-up roller for a water-washable heat transfer film, comprising a machine body, an adjusting roller disposed inside the machine body, an operation panel disposed on the top surface of the machine body, operation buttons disposed on the surface of the operation panel, a motor disposed on the side surface of the machine body, a rotating column fixedly mounted on the output end of the motor, a hydraulic cylinder disposed inside one end of the rotating column, a positioning block fixedly mounted on the output end of the hydraulic cylinder, a take-up roller sleeved on the outside of the positioning block, and a water-washable heat transfer film sleeved on the outer surfaces of the adjusting roller and the take-up roller.

[0006] Preferably, the take-up roller includes: a rotating rod, the rotating rod having an internal placement groove and an external sliding groove, one end of the sliding groove being connected to one end of the placement groove; a hydraulic cylinder being installed inside the placement groove; a movable column being fixedly mounted on the output end of the hydraulic cylinder being fitted inside the placement groove and in contact with the surface of the placement groove; a movable frame being installed on the surface of the movable column and the surface of the rotating rod; a connecting rod being fitted inside the movable frame; a movable cylinder being fitted outside the rotating rod; a sliding groove being formed on the internal surface of the movable cylinder; a movable frame being installed on the internal surface of the movable cylinder and inside the sliding groove; the other end of the connecting rod being fitted inside the movable frame; and a spring being fitted inside the rotating rod. A fixed cylinder is fixedly installed on the surface. A second spring is fitted inside the fixed cylinder. A moving rod is fitted inside the fixed cylinder, with its other end connected and fixed to the inner surface of the moving cylinder. Sealant is applied to both sides of the moving cylinder. A controller is placed inside one end of a rotating rod. A button is provided on the surface of the controller and located outside the rotating rod. A groove is formed on the surface of the moving cylinder, and a rotating arc block is fitted inside the groove. Rotating rods are installed on both sides of the rotating arc block. A torsion spring is fitted on the outer surface of the rotating rod. A gear is installed on one end of the rotating rod. A sliding block is fitted inside the groove and located outside the rotating rod. A rack is fixedly installed at the bottom of the sliding block. A conical pressure block is installed at the bottom of the rotating arc block. Here, pushing the sliding block drives the rack and gear transmission, causing the rotating arc block to rotate and reset via the torsion spring. The conical pressure block automatically presses down to fix one end of the film material, completely changing the traditional manual fixing method, avoiding operational errors and hand injuries, and improving winding efficiency and safety.

[0007] Preferably, a sprocket is fixedly mounted on the surface of the rotating column one, a rotating column two is sleeved inside the machine body, a sprocket two is mounted on one end of the rotating column two, a chain is driven to the outer surfaces of the sprocket one and the sprocket two, a half gear two is mounted on the other end of the rotating column two, a fixing ring is mounted on the inner surface of the machine body, a half gear three is sleeved at the front end of the fixing ring, a fixing plate is mounted at the rear end of the half gear three, a limit rod is mounted on the surface of the fixing plate, a spring three is sleeved on the outer surface of the limit rod, a limit frame is mounted on the inner surface of the machine body and the other end of the limit rod is sleeved inside the limit frame, a support frame is mounted on the surface of the half gear three, a spring four is sleeved inside the support frame, a moving strip is sleeved inside the support frame, a spring five is sleeved inside the moving strip, a limit post is sleeved inside the moving strip, a smoothing block is fixedly mounted on the top end of the limit post and the other end of the limit post is connected and fixed to the rear end of the smoothing block. Here, rotating column one drives rotating column two through sprockets and chains, and half gear two and half gear three mesh to form intermittent transmission, which drives the smoothing block on the support frame to move.

[0008] Preferably, the water-resistant heat transfer film is made of a green packaging material, the rotating columns are in two sets and symmetrically distributed inside the machine body, the hydraulic cylinder is initially in an activated state, and the positioning blocks are inserted into the two ends of the take-up roller for fixation. Here, the use of a water-resistant heat transfer film made of a green packaging material meets environmental protection requirements and reduces environmental pollution.

[0009] Preferably, the two sets of center points of the first connecting rod are limited by limiting pins. The two sets of the first connecting rod are in an "X" shape. Multiple sets of the first movable frame, the first connecting rod, and the second movable frame are arranged in an array inside the take-up roller. The rear end of the second movable frame is in a "T" shape and slidably connected to the second slide groove. The first connecting rod is a flattened ellipse. Here, the multiple arrayed connecting rod mechanisms allow the take-up roller to automatically expand or contract according to the film roll diameter, adapting to diameter changes at different take-up stages, maintaining uniform film winding tension, and avoiding loose winding due to diameter changes.

[0010] Preferably, one end of the first spring is connected and fixed to the inner surface of the placement groove, and the other end of the first spring is connected and fixed to the other end surface of the moving column. There are two sets of hydraulic cylinders and moving columns, symmetrically distributed inside the placement groove. Multiple sets of moving frames are distributed circumferentially on the surfaces of the rotating rod and the moving cylinder, and inside the sliding grooves. Here, the multiple circumferentially distributed moving frames and linkage mechanisms ensure that power is evenly transmitted to the moving cylinder, making the winding roller move synchronously during diameter adjustment, improving the stability and durability of the winding roller structure, and extending the service life of the equipment.

[0011] Preferably, the surface of gear one meshes with the surface of the rack. Gear one and the rack are located at both ends of the movable cylinder. One end of the torsion spring is connected and fixed to the inner surface of the groove, and the other end of the torsion spring is connected and fixed to the surface of the rotating rod two. There are six sets of movable cylinders, which are circumferentially distributed outside the rotating rod one, and the six sets of movable cylinders form a circular cylinder. Here, gear one meshes with the rack to drive the rotating arc block to rotate, and the torsion spring resets to ensure that the fixed pressure block accurately presses down on the film material.

[0012] Preferably, the surface of the smoothing block is in close contact with the surface of the water-washable heat transfer film. Multiple sets of springs and limiting posts are arranged in an array inside the moving strip and on the rear surface of the smoothing block. One end of each spring is connected and fixed to the interior of the moving strip, and the other end is connected and fixed to the bottom surface of the limiting post. The initial state of each spring is a contracted state. Here, the array distribution of multiple sets of springs and limiting posts ensures that the smoothing block adheres tightly to the film surface under spring tension, adapting to the winding requirements of film materials of different thicknesses.

[0013] Preferably, one end of the spring four is connected and fixed to the bottom end of the moving strip, and the other end of the spring four is connected and fixed to the interior of the support frame. The initial state of the spring four is semi-retracted. Here, the semi-retracted state of the spring four provides elastic support for the moving strip, so that the smoothing block has a buffering capacity when it contacts the membrane surface, avoiding excessive compression of the membrane material.

[0014] Preferably, one end of the third spring is fixedly connected to the surface of the fixed plate, and the other end of the third spring is fixedly connected to the surface of the support frame. The initial state of the third spring is stationary. The limiting rod is semi-circular in shape. The surface of the second half-gear meshes with the surface of the third half-gear. The surfaces of the first and second sprockets mesh with the surface of the chain. Here, the initial stationary state of the third spring provides support for the limiting rod, the meshing of the second and third half-gears achieves precise intermittent transmission, and the sprocket and chain transmission ensures stable power transmission.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0016] 1. In this invention, by setting up a machine body, adjusting roller, and operation panel structure, a rotating arc block structure with gear rack and torsion spring linkage is adopted in the film material fixing stage. The operator can automatically fix one end of the film material by pushing the sliding block, which is simple and safe and avoids the risks and inefficiencies of manual operation. During the winding process, the diameter of the winding roller is adaptively adjusted by the hydraulic cylinder two driving the linkage mechanism, which effectively avoids wrinkles and loosening and improves the winding quality and film flatness. After winding is completed, the expansion and contraction of the moving cylinder is controlled by restarting the hydraulic cylinder two, which can quickly widen the gap between the film roll and the roller body, easily achieve the film roll detachment, significantly reduce the difficulty of disassembly, save time and costs, greatly improve production efficiency, and meet the needs of modern industrial production for efficient and precise winding.

[0017] 2. In this invention, a structure consisting of a sprocket, a rotating column, a chain, a half-gear, a fixed ring, a half-gear, a fixed plate, a limiting rod, a spring, and a limiting frame is constructed. The sprocket and chain drive rotate the rotating column, and the meshing of the half-gears creates intermittent motion, causing the support frame to move the smoothing block back and forth at a set frequency. Springs four and five, in conjunction with the limiting rod, ensure that the smoothing block remains firmly against the surface of the washable heat transfer film under elastic buffering, continuously smoothing wrinkles during winding. This design avoids the wrinkling problem caused by uneven tension in traditional winding processes, ensuring a smooth and flat film surface, improving product quality, reducing film waste due to wrinkles, increasing winding efficiency, and extending equipment lifespan.

[0033] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0034] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification. Example 1

[0035] Please see Figures 1-11 , Figure 13 The present invention provides a technical solution: a take-up roller for a water-washable heat transfer film, comprising a body 1, an adjusting roller 2 disposed inside the body 1, an operation panel 3 disposed on the top surface of the body 1, an operation button 4 disposed on the surface of the operation panel 3, a motor 5 disposed on the side surface of the body 1, a rotating column 6 fixedly mounted on the output end of the motor 5, a hydraulic cylinder 7 disposed inside one end of the rotating column 6, a positioning block 8 fixedly mounted on the output end of the hydraulic cylinder 7, a take-up roller 9 sleeved on the outside of the positioning block 8, and a water-washable heat transfer film sleeved on the outer surface of the adjusting roller 2 and the take-up roller 9.

[0036] The take-up roller 9 includes: a rotating rod 10, with a placement groove 11 inside the rotating rod 10 and a sliding groove 12 on the outer surface of the rotating rod 10. One end of the sliding groove 12 is connected to one end of the placement groove 11. A hydraulic cylinder 13 is installed inside the placement groove 11. A movable column 14 is fixedly installed at the output end of the hydraulic cylinder 13 and is fitted inside the placement groove 11. The movable column 14 is in contact with the surface of the placement groove 11. A movable frame 15 is installed on the surface of the movable column 14 and the surface of the rotating rod 10. A connecting rod 16 is fitted inside the movable frame 15.

[0037] A movable cylinder 17 is sleeved on the outside of the rotating rod 10. A sliding groove 18 is opened on the inner surface of the movable cylinder 17. A movable frame 19 is set inside the inner surface of the movable cylinder 17 and inside the sliding groove 18. The other end of the connecting rod 16 is sleeved inside the movable frame 19. A spring 20 is sleeved inside the rotating rod 10. A fixed cylinder 21 is fixedly installed on the surface of the rotating rod 10. A spring 22 is sleeved inside the fixed cylinder 21. A movable rod 23 is sleeved inside the fixed cylinder 21. The other end of the movable rod 23 is connected and fixed to the inner surface of the movable cylinder 17. Sealant 24 is provided on both sides of the movable cylinder 17.

[0038] A controller is placed inside one end of the rotating rod 10. The controller has a button on its surface and is located outside the rotating rod 10. The surface of the moving cylinder 17 has a groove 25. A rotating arc block 26 is fitted inside the groove 25. A rotating rod 27 is installed on both sides of the rotating arc block 26. A torsion spring 28 is fitted on the outer surface of the rotating rod 27. A gear 29 is installed on one end of the rotating rod 27. A sliding block 30 is fitted inside the groove 25 and is located outside the rotating rod 10. A rack 31 is fixedly installed at the bottom end of the sliding block 30. A fixed pressure block 32 is installed at the bottom end of the rotating arc block 26. The fixed pressure block 32 is conical in shape. The rotating rod 10 is a component of the take-up roller 9 and is installed at the central axis of the take-up roller 9.

[0039] When using the equipment, firstly, the operator starts the equipment using the operation button 4 on the operation panel 3. The motor 5 starts working, driving the rotating column 6 to rotate. Next, the take-up roller 9 is installed on the rotating column 6, and the hydraulic cylinder 7 is activated, causing the positioning block 8 at its output end to insert into the end of the take-up roller 9, completing the fixed installation of the take-up roller 9. Subsequently, the water-washable heat transfer film is wrapped around the adjusting roller 2 and placed on the surface of the take-up roller 9, ready for the winding operation.

[0040] At the start of winding, the operator pushes the sliding block 30. The movement of the sliding block 30 moves the rack 31, which in turn rotates the gear 29. The rotation of the gear 29 rotates the rotating rod 27, causing the torsion spring 28 to contract. Simultaneously, the rotating rod 27 rotates the rotating arc block 26. At this point, one end of the washable heat transfer film is positioned inside the groove 25. Then, the operator removes their hand from the sliding block 30, and the torsion spring 28 resets, causing the rotating arc block 26 to rotate back. The fixing block 32 presses down and fixes one end of the washable heat transfer film. After the film is fixed, the motor 5 drives the winding roller 9 to rotate, starting the winding of the washable heat transfer film.

[0041] During the winding process, if the diameter of the winding roller 9 needs to be adjusted to adapt to different winding requirements, hydraulic cylinder 2 13 is activated. The output end of hydraulic cylinder 2 13 pushes the moving column 14 to move within the placement groove 11. The movement of the moving column 14 drives the moving frame 15 to move, which, through the connecting rod 16, causes the moving frame 19 to slide within the slide groove 18, thereby causing the moving cylinder 17 to expand or contract outward, achieving adaptive adjustment of the diameter of the winding roller 9. Springs 1 20 and 2 22 play a buffering and auxiliary reset role in this process. After winding is completed, hydraulic cylinder 2 13 is activated again to expand the moving cylinder 17 outward, widening the gap between the winding roller 9 and the film roll. Then, the moving cylinder 17 contracts, reducing the contact pressure between the winding roller 9 and the film roll, so as to quickly remove the wound washable heat transfer film from the surface of the winding roller 9. Throughout the winding process, the adjusting roller 2 continuously adjusts the tension of the washable heat transfer film to ensure winding quality.

[0042] Please see Figures 1-13 The material of the water-resistant heat transfer film is green packaging material. There are two sets of rotating columns 6, which are symmetrically distributed inside the machine body 1. The initial state of the hydraulic cylinder 7 is the start state. The positioning blocks 8 are inserted into the two ends of the take-up roller 9 for fixation. The two sets of center points of the connecting rod 16 are limited by the limiting pins. The two sets of connecting rod 16 are in the shape of an "X". There are multiple sets of moving frame 15, connecting rod 16 and moving frame 2 19, which are arranged in an array inside the take-up roller 9. The rear end of the moving frame 2 19 is in the shape of a "T" and is slidably connected to the slide groove 2 18. The shape of the connecting rod 16 is a flat ellipse. One end of the spring 20 is connected and fixed to the inner surface of the placement groove 11. The other end of the spring 20 is connected and fixed to the other end surface of the moving column 14.

[0043] Two sets of hydraulic cylinders 13 and moving columns 14 are symmetrically distributed inside the placement groove 11. Multiple sets of moving frames 15 and 19 are circumferentially distributed on the surfaces of rotating rod 10 and moving cylinder 17, and inside sliding grooves 12 and 18. The surface of gear 29 meshes with the surface of rack 31. Gear 29 and rack 31 are located at both ends of moving cylinder 17. One end of torsion spring 28 is connected and fixed to the inner surface of groove 25, and the other end of torsion spring 28 is connected to rotating rod 10. The surfaces of 7 are connected and fixed. There are six sets of movable cylinders 17, which are distributed in a circle outside the rotating rod 10. The six sets of movable cylinders 17 form a circular column. The surface of the smoothing block 49 is in close contact with the surface of the water-resistant heat transfer film. There are multiple sets of springs 5 ​​47 and limiting posts 48, which are arranged in an array inside the movable bar 46 and on the rear end surface of the smoothing block 49. One end of spring 5 47 is connected and fixed to the inside of the movable bar 46, and the other end of spring 5 47 is connected and fixed to the bottom surface of the limiting post 48.

[0044] The initial state of spring 5 47 is the retracted state. One end of spring 45 is connected and fixed to the bottom end of the moving bar 46, and the other end of spring 45 is connected and fixed to the inside of the support frame 44. The initial state of spring 45 is the semi-retracted state. One end of spring 3 42 is connected and fixed to the surface of the fixed plate 40, and the other end of spring 3 42 is connected and fixed to the surface of the support frame 44. The initial state of spring 3 42 is the stationary state. The shape of the limiting rod 41 is semi-circular. The surface of half gear 2 37 meshes with the surface of half gear 3 39. The surfaces of sprocket 1 33 and sprocket 2 35 mesh with the surface of the chain 36. When the diameter of the diaphragm roll changes, spring 45 dynamically adjusts the pressure of the smoothing block 49 to ensure a stable smoothing effect, while reducing mechanical wear and improving the reliability and service life of the smoothing mechanism. Example 2

[0045] Please see Figure 2 , Figure 8 , Figures 11-12 A sprocket 33 is fixedly installed on the surface of the rotating column 6. A rotating column 34 is fitted inside the machine body 1. A sprocket 35 is installed at one end of the rotating column 34. A chain 36 is connected to the outer surfaces of the sprocket 33 and the sprocket 35. A half gear 37 is installed at the other end of the rotating column 34. A fixing ring 38 is installed on the inner surface of the machine body 1. A half gear 39 is fitted at the front end of the fixing ring 38. A fixing plate 40 is installed at the rear end of the half gear 39. A limit rod 41 is installed on the surface of the fixing plate 40. A spring 42 is fitted on the outer surface of the limit rod 41. A limit frame 43 is installed on the inner surface of the machine body 1, and the other end of the limit rod 41 is fitted inside the limit frame 43.

[0046] A support frame 44 is mounted on the surface of half gear 39. A spring 45 is fitted inside the support frame 44. A moving strip 46 is fitted inside the support frame 44. A spring 47 is fitted inside the moving strip 46. A limiting post 48 is fitted inside the moving strip 46. A smoothing block 49 is fixedly mounted on the top of the limiting post 48, and the other end of the limiting post 48 is connected and fixed to the rear end of the smoothing block 49. When the motor 5 operates, it drives the rotating column 6 to rotate. The sprocket 33 on the surface of the rotating column 6 is driven by the chain 36, causing the sprocket 35 to drive the rotating column 34 to rotate synchronously. The half gear 37 at the other end of the rotating column 34 rotates accordingly. Since the center of half gear 39 is the same as the center of the take-up roller 9, when half gear 37 meshes with half gear 39, it drives half gear 39 to perform a circular motion around the fixed ring 38. The limiting rod 41 on the fixed plate 40 at the rear end of half gear 39 slides within the limiting frame 43, and spring 42 provides buffering and restoring force.

[0047] When half-gear 39 rotates, its surface support frame 44 drives the smoothing block 49 to move in a circular motion around the center of the take-up roller 9. The arc-shaped contact surface of the smoothing block 49 always adheres to the surface of the water-washable heat transfer film. Inside the support frame 44, spring 45 causes the moving strip 46 to elastically extend and retract. In conjunction with spring 5 47 and limit post 48 inside the moving strip 46, this ensures that the smoothing block 49 contacts the film surface with appropriate pressure, adapting to changes in the film roll diameter. When half-gear 2 37 and half-gear 39 disengage, spring 3 42 drives half-gear 39 to reset. When they re-engage, the above actions are repeated, allowing the smoothing block 49 to continuously smooth the film surface, eliminating wrinkles generated during the winding process and ensuring the film material is wound smoothly.

[0048] Working principle: When using the equipment, firstly, the operator starts the equipment via the operation button 4 on the operation panel 3. The motor 5 starts working, driving the rotating column 6 to rotate. Next, the take-up roller 9 is installed on the rotating column 6, and the hydraulic cylinder 7 is activated, causing the positioning block 8 at its output end to insert into the end of the take-up roller 9, completing the fixed installation of the take-up roller 9. Subsequently, the water-washable heat transfer film is wrapped around the adjusting roller 2 and placed on the surface of the take-up roller 9, ready for the winding operation.

[0049] At the start of winding, the operator pushes the sliding block 30. The movement of the sliding block 30 moves the rack 31, which in turn rotates the gear 29. The rotation of the gear 29 rotates the rotating rod 27, causing the torsion spring 28 to contract. Simultaneously, the rotating rod 27 rotates the rotating arc block 26. At this point, one end of the washable heat transfer film is positioned inside the groove 25. Then, the operator removes their hand from the sliding block 30, and the torsion spring 28 resets, causing the rotating arc block 26 to rotate back. The fixing block 32 presses down and fixes one end of the washable heat transfer film. After the film is fixed, the motor 5 drives the winding roller 9 to rotate, starting the winding of the washable heat transfer film.

[0050] During the winding process, if it is necessary to adjust the diameter of the winding roller 9 to adapt to different winding requirements, the hydraulic cylinder 13 is activated. The output end of the hydraulic cylinder 13 pushes the moving column 14 to move in the placement groove 11. The movement of the moving column 14 drives the moving frame 15 to move. Through the connecting rod 16, the moving frame 19 slides in the slide groove 18, thereby driving the moving cylinder 17 to expand or contract outward, realizing the adaptive adjustment of the diameter of the winding roller 9. The spring 20 and the spring 22 play the role of buffering and auxiliary reset in this process.

[0051] After winding is complete, hydraulic cylinder 13 is activated again to expand the moving drum 17 outward, widening the gap between the winding roller 9 and the film roll. Then, the moving drum 17 retracts, reducing the contact pressure between the winding roller 9 and the film roll, allowing the washed-resistant heat transfer film to be quickly removed from the surface of the winding roller 9. Throughout the winding process, the adjusting roller 2 continuously adjusts the tension of the washed-resistant heat transfer film to ensure winding quality. Simultaneously, when motor 5 is running, it drives rotating column 6 to rotate. The sprocket 33 on the surface of rotating column 6 is driven by chain 36, causing sprocket 35 to drive rotating column 34 to rotate synchronously. The half-gear 37 at the other end of rotating column 34 rotates accordingly. Since the center of the third half gear 39 is the same as the center of the take-up roller 9, when the second half gear 37 meshes with the third half gear 39, it drives the third half gear 39 to make a circular motion around the fixed ring 38. The limiting rod 41 on the fixed plate 40 at the rear end of the third half gear 39 slides in the limiting frame 43, and the third spring 42 provides buffering and restoring force.

[0052] When half-gear 39 rotates, its surface support frame 44 drives the smoothing block 49 to move in a circular motion around the center of the take-up roller 9. The arc-shaped contact surface of the smoothing block 49 always adheres to the surface of the water-washable heat transfer film. Inside the support frame 44, spring 45 causes the moving strip 46 to elastically extend and retract. In conjunction with spring 5 47 and limit post 48 inside the moving strip 46, this ensures that the smoothing block 49 contacts the film surface with appropriate pressure, adapting to changes in the film roll diameter. When half-gear 2 37 and half-gear 39 disengage, spring 3 42 drives half-gear 39 to reset. When they re-engage, the above actions are repeated, allowing the smoothing block 49 to continuously smooth the film surface, eliminating wrinkles generated during the winding process and ensuring the film material is wound smoothly.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
