Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 This utility model provides a technical solution: an automatic winding mechanism for water transfer printing film paper, including a mounting plate 1, a disassembly structure 2 on the top left side of the mounting plate 1, a cleaning structure 3 on the top of the mounting plate 1, winding adjustment structures 4 on both the left and right sides inside the disassembly structure 2 and the cleaning structure 3, and a transmission roller mechanism 5 on the top right side of the mounting plate 1.

[0027] Please see Figure 2The winding adjustment structure 4 includes a winding drum 41. A fixing sleeve 42 is fixedly connected to the front side of the inner wall of the winding drum 41. A rotating shaft 43 is movably connected to the inner wall of the fixing sleeve 42. A stepper motor 44 is fixedly connected to the front end of the rotating shaft 43. The bottom of the stepper motor 44 is fixedly connected to the inner wall of the winding drum 41. A bidirectional threaded rod 45 is fixedly connected to the rear end of the rotating shaft 43. A fixing sleeve 46 is movably connected to the middle position of the outer wall of the bidirectional threaded rod 45.

This causes one end of the water transfer film paper to wrap around the outer wall of the winding adjustment structure 4 inside the disassembly structure 2. Multiple stepper motors 44 are activated according to the size of the water transfer film paper, causing the stepper motors 44 to drive the rotating shaft 43 to rotate inside the fixed sleeve 42, which in turn drives the bidirectional threaded rod 45 to rotate. The rotation of the bidirectional threaded rod 45 causes the two sliding discs 47 to move closer or further apart. During the movement of the two sliding discs 47, the guide block 49 slides inside the rectangular through hole 48. At the same time, the guide block 49 guides and limits the movement of the sliding discs 47. The movement of the sliding discs 47 drives the limiting plate 40 to move, thereby limiting and guiding the water transfer film paper according to its size, improving the stability during winding.

[0028] Please see Figure 3The disassembly structure 2 includes two support plates 21. The bottom of the support plate 21 is fixedly connected to the top of the mounting plate 1. A connecting shaft 22 is movably connected to the inner wall of the support plate 21. A connecting shaft 23 is fixedly connected to the front end of the connecting shaft 22.

The ends of the two conveyor belts 24 that are close to each other are fixedly connected to the front and rear ends of the take-up drum 41. A drive is fixedly connected to the rear end of the rear connecting shaft 22. Motor 205, with a support frame 206 fixedly connected to its bottom. The front side of the support frame 206 is fixedly connected to the rear side of the rear support plate 21. Starting the drive motor 205 causes the rear connecting shaft 22 to rotate, which in turn rotates the rear fixed plate 25, clamping block 202, rectangular block 203, fixed disc 204, and the winding adjustment structure 4 inside the disassembly structure 2, thereby winding up the water transfer printing film. The rotation of the winding adjustment structure 4 inside the disassembly structure 2 causes the front fixed disc 204, rectangular block 203, clamping block 202, and fixed plate 25 to rotate the connecting shaft 23, which in turn drives the cleaning structure 3 via the conveyor belt 24. The process involves cleaning the outer wall of the water transfer printing film. After winding, the motor housing 27 is positioned upwards, and two stepper motors 29 are started. The stepper motors 29 drive the rotating shaft 28 to rotate, which in turn drives the lead screw 20 to rotate. The rotation of the lead screw 20 causes the slider 201 to move on the outer wall of the lead screw 20, which in turn causes the clamping block 202 on the outer wall of the slider 201 to move upwards, thereby releasing the clamping of the rectangular block 203 and releasing the limit on the winding adjustment structure 4 inside the disassembly structure 2. This facilitates the disassembly of the winding adjustment structure 4 with the water transfer printing film, which can then be replaced for the next winding operation.

[0029] Please see Figure 4The cleaning structure 3 includes two fixed plates 31. Support plates 32 are fixedly connected to both sides of the fixed plates 31. The bottom of the support plates 32 is fixedly connected to the top of the mounting plate 1. A connecting shaft 33 is movably connected to the inner wall of the support plates 32. The ends of the two connecting shafts 33, which are close to each other, are fixedly connected to the front and rear ends of the winding drum 41.

A connecting post 37 is fixedly connected to the front end of the lower front connecting shaft 35. A connecting shaft 38 is fixedly connected to the front end of the connecting post 37. The outer wall of the connecting shaft 38 is fitted onto the other end of the inner wall of the conveyor belt 24. A fixed roller 39 is fixedly connected to the ends of the front and rear connecting shafts 35, which are close to each other. A cleaning cotton 30 is fixedly connected to the outer wall of the fixed roller 39. One end of the water transfer film paper is then... The two connecting shafts 33 on the right are close to each other at one end of the outer wall of the winding adjustment structure 4, the two cleaning cotton 30 inside, and the two connecting shafts 33 on the left are close to each other at one end of the outer wall of the winding adjustment structure 4, and are wound around the outer wall of the winding adjustment structure 4 in the disassembly structure 2. When the disassembly structure 2 starts to wind up, the water transfer printing film paper is driven by the conveyor belt 24 to drive the connecting shaft 38 to rotate the connecting column 37, which in turn drives the front lower connecting shaft 35 to rotate. The rotation of the front lower connecting shaft 35 drives the lower fixed roller 39 to rotate, which in turn drives the rear lower connecting shaft 35 to rotate. The two meshing gears 36 drive the rear upper connecting shaft 35 to rotate, which in turn drives the upper fixed roller 39 to rotate. The rotation of the fixed roller 39 drives the cleaning cotton 30 to rotate, thereby cleaning the dust and impurities on the outer wall of the water transfer printing film paper, avoiding affecting the quality of the water transfer printing film paper and improving the practicality of the device.

[0030] Working principle:

[0031] One end of the water transfer printing film is passed through the inside of the transmission roller mechanism 5 and the outer wall of the right-side winding adjustment structure 4 inside the cleaning structure 3, the inside of the cleaning structure 3, and the outer wall of the left-side winding adjustment structure 4 inside the cleaning structure 3, so that one end of the water transfer printing film is wrapped around the outer wall of the winding adjustment structure 4 inside the disassembly structure 2. According to the size of the water transfer printing film, multiple stepper motors 44 are activated, so that the stepper motors 44 drive the rotating shaft 43 to rotate inside the fixed sleeve 42, which in turn drives the bidirectional threaded rod 45 to rotate. The rotation of the bidirectional threaded rod 45 drives the two sliding discs 47 to move closer or further apart. During the movement of the two sliding discs 47, the guide block 49 slides inside the rectangular through hole 48. At the same time, the guide block 49 guides and limits the movement of the sliding discs 47. The movement of the sliding discs 47 drives the limiting plate 40 to move, thus limiting and guiding the water transfer printing film according to its size, improving the stability during winding.

[0032] By starting the drive motor 205, the rear connecting shaft 22 rotates, which in turn drives the rear fixing plate 25, clamping block 202, rectangular block 203, fixing plate 204, and the winding adjustment structure 4 inside the disassembly structure 2 to rotate, thereby winding up the water transfer printing film paper. The rotation of the winding adjustment structure 4 inside the disassembly structure 2 then drives the front fixing plate 204, rectangular block 203, clamping block 202, and fixing plate 25 to rotate the connecting shaft 23, which in turn drives the cleaning structure 3 via the conveyor belt 24 to clean the outer wall of the water transfer printing film paper. After winding is complete, the motor housing is... 27. Stop at the upward position, then start the two stepper motors 29. The stepper motors 29 drive the rotating shaft 28 to rotate, which in turn drives the lead screw 20 to rotate. The rotation of the lead screw 20 drives the slider 201 to move on the outer wall of the lead screw 20, which in turn drives the clamping block 202 on the outer wall of the slider 201 to move upward, thereby releasing the clamping of the rectangular block 203 and releasing the limit on the winding adjustment structure 4 inside the disassembly structure 2. This makes it easy to disassemble the winding adjustment structure 4 with water transfer film paper. At this time, the winding adjustment structure 4 can be replaced for the next winding operation.

[0033] By bringing one end of the water transfer printing film paper close to the outer wall of the winding adjustment structure 4 at one end via two connecting shafts 33 on the right, the inside of the two cleaning cotton 30, and the two connecting shafts 33 on the left close to the outer wall of the winding adjustment structure 4 at one end, and winding it around the outer wall of the winding adjustment structure 4 in the disassembly structure 2, when the disassembly structure 2 starts to wind the water transfer printing film paper, the connecting shaft 38 is driven by the conveyor belt 24 to rotate the connecting column 37, which in turn drives the lower front connecting shaft 35 to rotate. The rotation of the lower front connecting shaft 35 drives the lower fixed roller 39 to rotate, which in turn drives the lower rear connecting shaft 35 to rotate. The two meshing gears 36 drive the upper rear connecting shaft 35 to rotate, which in turn drives the upper fixed roller 39 to rotate. The rotation of the fixed roller 39 drives the cleaning cotton 30 to rotate, thereby cleaning the dust and impurities on the outer wall of the water transfer printing film paper, avoiding any impact on the quality of the water transfer printing film paper and improving the practicality of the device.
