DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present utility model are given for the purpose of illustration and description, and are not exhaustive or limited to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0017] Embodiment: Please refer to Figure 1 - Figure 4 , the present utility model provides a technical solution: a plastic film winding machine facilitating the switching of winding rollers, comprising: a base 1; a threaded rod 2, the outer wall of the threaded rod 2 being rotatably connected to the inner wall of the base 1; a switching device 3, the outer wall of the switching device 3 being rotatably connected to the inner wall of the base 1; a guiding device 4, the outer wall of the bottom of the guiding device 4 being rotatably connected to the inner wall of the top of the base 1; a clamping device 5, the bottom of the clamping device 5 being slidably connected to the top of the base 1; a counterweight 6, the outer wall of the counterweight 6 being fixedly connected to the outer wall of the guiding device 4.

[0018] The switching device 3 includes a rotating disk 31, the inner wall of the rotating disk 31 being rotatably connected to a rotating shaft 32, the outer wall of the rotating shaft 32 being fixedly connected to a rotating roller 33, one end of the rotating roller 33 away from the rotating disk 31 being fixedly connected to a connecting head 34, and one end of the rotating disk 31 away from the rotating shaft 32 being rotatably connected to the inner wall of the base 1. The setting of the switching device 3 facilitates the switching of the position of the rotating roller 33 and cooperates with the clamping device 5 to complete the clamping use of the rotating roller 33.

[0019] The guiding device 4 includes a rotating plate 41. An arc-shaped plate 42 is fixedly connected to the top of the rotating plate 41. An anti-fall block 43 is fixedly connected to the side wall of the rotating plate 41. A blocking block 44 is arranged outside the anti-fall block 43. The outer wall of the bottom of the rotating plate 41 is rotatably connected to the inner wall of the top of the base 1. The bottom of the blocking block 44 is fixedly connected to the top of the base 1. One side of the rotating plate 41 away from the anti-fall block 43 is fixedly connected to the outer wall of the counterweight 6. When the moving block 51 moves away from the switching device 3, at this time, the limiting plate 53 on the moving block 51 moves away from the anti-fall block 43 on the rotating plate 41. At this time, under the action of the gravity of the counterweight 6, the two rotating plates 41 rotate towards both sides of the switching device 3 respectively until further rotation is blocked by the inclined surface of the blocking block 44. At this time, the winding roller is exposed within the operator's line of sight, facilitating the operator to replace the corresponding winding roller for winding operation. After the winding position is fixed, the rotating plate 41 is placed vertically, and the clamping device 5 is used to clamp the winding roller through the threaded rod 2. After clamping, the unused winding rollers are limited by the guiding ring 57. Through the supporting force of the guiding ring 57 on the winding roller, the force on the rotating shaft 32 is reduced, delaying the damage time of the rotating shaft 32. At the same time, the limiting plate 53 moves above the anti-fall block 43 on the rotating plate 41 and cooperates with the triangular protrusion on the top of the anti-fall block 43, thereby completing the position fixation of the rotating plate 41.

[0020] The clamping device 5 includes a moving block 51. The inner wall of the moving block 51 is threadedly connected to the outer wall of the threaded rod 2 through a threaded hole 52, and the threaded hole 52 is opened in the wall of the moving block 51. Limiting plates 53 are fixedly connected to both sides of the moving block 51. A servo motor 54 is fixedly connected to the top of the moving block 51. The output end of the servo motor 54 is fixedly connected to a connecting sleeve 55. A connecting rod 56 is fixedly connected to the inner side wall of the connecting sleeve 55. A guiding ring 57 is fixedly connected to the outer wall of the moving block 51. The bottom of the moving block 51 is slidably connected to the top of the base 1. The outer wall of the connecting sleeve 55 is rotatably connected to the inner wall of the top of the moving block 51. When it is necessary to replace the winding roller, rotate the threaded rod 2 on the base 1. The threaded rod 2 is positioned by the base 1 and pushes the moving block 51 to move through the threaded hole 52 during rotation. At this time, the moving block 51 is driven to move away from the switching device 3, and the connecting rod 56 on the connecting sleeve 55 slides out from the connecting head 34. At this time, the rotating roller 33 corresponding to the production needs is moved to a position coaxial with the axis of the connecting sleeve 55. Then rotate the threaded rod 2 in the reverse direction, and the moving block 51 approaches the switching device 3 accordingly. Since the connecting heads 34 on the winding rollers connected to each rotating shaft 32 on the rotating disc 31 are of the same specification, the connecting rod 56 can smoothly slide into the groove on the connecting head 34 until the connecting sleeve 55 contacts the circular protrusion of the connecting head 34 and then stops. At this time, drive the servo motor 54, and the servo motor 54 drives the connecting sleeve 55 to rotate, thereby driving the winding roller to rotate.

[0021] Working principle:

[0022] During use, the switching device 3 is provided to facilitate the position switching of the rotating roller 33, and cooperate with the clamping device 5 to complete the clamping of the rotating roller 33. When it is necessary to replace the winding roller, rotate the threaded rod 2 on the base 1. The threaded rod 2 is positioned by the base 1 and pushes the moving block 51 to move through the threaded hole 52 during rotation. At this time, the moving block 51 is driven away from the switching device 3, and the connecting rod 56 on the connecting sleeve 55 slides out of the connecting head 34. At this time, the rotating roller 33 corresponding to the production needs is moved to a position coaxial with the axis of the connecting sleeve 55. Then, rotate the threaded rod 2 in the reverse direction, and the moving block 51 approaches the switching device 3 accordingly. Since the connecting heads 34 on the winding rollers connected to each rotating shaft 32 on the rotating disc 31 are of the same specification, the connecting rod 56 can smoothly slide into the groove on the connecting head 34 until the connecting sleeve 55 contacts the circular protrusion of the connecting head 34 and then stops. At this time, drive the servo motor 54. The servo motor 54 drives the connecting sleeve 55 to rotate, and then drives the winding roller to rotate, simplifying the steps of replacing the winding roller and saving the time for switching the winding roller.

[0023] The guiding device 4 is provided to protect the rotating roller 33 and guide the plastic film through the arc-shaped plate 42 to assist in winding the plastic film. When the moving block 51 moves away from the switching device 3, the limiting plate 53 on the moving block 51 moves away from the anti-falling block 43 on the rotating plate 41. At this time, under the gravity of the counterweight block 6, the two rotating plates 41 rotate towards the two sides of the switching device 3 respectively until they are blocked by the inclined surface of the blocking block 44 and further rotation is blocked. At this time, the winding roller is exposed within the sight of the operator, facilitating the operator to replace the corresponding winding roller for winding operation. After the winding position is fixed, place the rotating plate 41 vertically and control the clamping device 5 to clamp the winding roller through the threaded rod 2. After clamping, the remaining unused winding rollers are limited by the guiding ring 57. Through the supporting force of the guiding ring 57 on the winding roller, the force on the rotating shaft 32 is reduced, delaying the damage time of the rotating shaft 32. At the same time, the limiting plate 53 moves above the anti-falling block 43 on the rotating plate 41 and cooperates with the triangular protrusion at the top of the anti-falling block 43, thereby completing the position fixing of the rotating plate 41, and further protecting multiple winding rollers including the rotating roller 33 on the rotating disc 31.
