[0001] The utility model relates to the technical field of protective film coating, in particular to a protective film coating roller shaft. Background Art

[0002] The protective film can be divided into digital product protective film, automobile protective film, household protective film, food preservation protective film, etc. according to its use; during the processing and production of the protective film, coating operation is required, and the coating operation is generally carried out by a coating machine, and a roller shaft for supporting the protective film is arranged on the coating machine; therefore, a protective film coating roller shaft is used to support the coating of the protective film.

[0003] The prior art such as the utility model with the publication number of CN220126687U discloses a protective film coating roller shaft. The patent adopts a hollow roller shaft. A through groove is formed on the surface of the roller shaft along its length direction. A rotating shaft is rotatably arranged inside the roller shaft. An anti-adhesive film roll is sleeved on the rotating shaft. A sliding cavity is formed on the side wall of the through groove. A pressing plate is slidably arranged in the sliding cavity so that the pressing plate can cover the through groove. A limiting groove communicated with the sliding cavity is formed on the side surface of the roller shaft. A sliding block is arranged on the pressing plate, and at least part of the sliding block extends out of the roller shaft from the limiting groove; the equipment of the utility model solves the problem that when replacing the anti-adhesive film of the existing coating roller, it is very cumbersome to disassemble the coating roller for replacement.

[0004] In daily work, during the process of the equipment supporting and moving the material, when the protective film is coated and moves on the surface of the roller, deviation is likely to occur, resulting in the protective film being coated and moving torsionally on the surface of the roller, causing damage to the coating of the protective film. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the defect that deviation of materials occurs in the prior art, resulting in damage to the edges of the materials, and to propose a protective film coating roller shaft.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a protective film coating roller shaft, including a placement plate, a connecting frame, a roller and a limiting device. The upper surface of the placement plate is fixedly connected with the connecting frame. The roller is rotatably connected inside the connecting frame. The limiting device is arranged inside the connecting frame. The limiting device includes a limiting ring and a positioning rod. The limiting ring is slidably connected with the surface of the roller. The positioning rod is fixedly connected with the inside of the connecting frame. The limiting ring is slidably connected with the surface of the positioning rod. A positive and negative threaded rod is rotatably connected inside the connecting frame. A nut is fixedly connected with the surface of the limiting ring. The positive and negative threaded rod is rotatably connected with the inner wall of the limiting ring.

[0007] Further, the positive and negative threaded rod is internally threadedly connected to the nut, and one end of the positive and negative threaded rod is fixedly connected with a connection cap. By setting the positive and negative threaded rod, the nut can be moved, reducing the situation that it is difficult for the limit ring to move during the use of the device, resulting in the difficulty of the limit ring to limit the material.

[0008] Further, one end of the positive and negative threaded rod is fixedly connected with a connection head, and the surface of the connection head is fixedly connected with a motor. Setting the motor facilitates the rotation of the positive and negative threaded rod.

[0009] Further, the surface of the motor is fixedly connected with a base, and the base is fixedly connected with the surface of the connection frame. Setting the base facilitates the limitation of the motor.

[0010] Further, a cleaning device is arranged on the side of the connection frame. The cleaning device includes a cleaning plate and a connection block. The connection block is fixedly connected with the side of the connection frame. The cleaning plate is arranged on the side of the roller. The surface of the connection block is fixedly connected with a positioning block. The cleaning plate is arranged on the surface of the positioning block. A sliding hole is formed in the surface of the positioning block, and a clamping plate is slidably connected to the inner wall of the sliding hole. By setting the cleaning plate, the surface of the roller can be cleaned, reducing the situation that foreign matters are easily adsorbed on the surface of the roller during the use of the device, resulting in the pollution of the material.

[0011] Further, one end of the clamping plate is fixedly connected with a spring, and the end of the spring away from the clamping plate is fixedly connected with the inner wall of the sliding hole. Setting the spring facilitates applying a reset elastic force to the clamping plate.

[0012] Further, the surface of the clamping plate is fixedly connected with a slider, and the slider is slidably connected to the inside of the sliding hole. Setting the slider facilitates the movement of the sliding plate.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] 1. In the present utility model, when the device is in use, the user places and moves the protective film coating on the surface of the roller to support the protective film coating. When the device is in use, the user starts the motor, and then the motor drives the positive and negative threaded rod to rotate when it rotates. Then, when the positive and negative threaded rod rotates, it drives the nut to move. Then, the movement of the nut drives the limit ring to move on the surface of the positioning rod. By setting the limiting device, the protective film coating is effectively limited, playing a role in limiting the movement of the protective film coating with different widths. Reducing the situation that when the protective film coating moves on the surface of the roller during the use of the device, it is easy to deviate, resulting in the twisted movement of the protective film coating on the surface of the roller and damaging the protective film coating, improving the practicability of the device.

[0015] 2. In the present utility model, by providing a cleaning device, when the device is in use, the user slides the slider, and then when the slider moves, it drives the clamping plate to move. When the clamping plate moves, it drives the spring to displace and deform to generate elastic force. Then the clamping plate moves away from the surface of the cleaning plate, and then the cleaning plate loses restraint, and the cleaning plate is pulled away from the surface of the positioning block. By providing the cleaning device, the surface of the roller is effectively cleaned, which plays a role in cleaning the surface of the roller, reduces the situation that dust or debris is easily adsorbed on the surface of the roller when the device is in use. When the roller jacks up and levels the protective film coating, dust is likely to contaminate the protective film coating, resulting in defective products of the protective film coating, and improves the practicability of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a protective film coating roller shaft, including a placing plate 1, a connecting frame 2, a roller 3 and a limiting device 4. The upper surface of the placing plate 1 is fixedly connected with the connecting frame 2, and the roller 3 is rotatably connected inside the connecting frame 2.

[0023] Next, the specific settings and functions of its limiting device 4 and cleaning device 5 will be specifically described.

[0024] In this implementation: The limiting device 4 is arranged inside the connecting frame 2. The limiting device 4 includes a limiting ring 41 and a positioning rod 42. The limiting ring 41 is slidably connected to the surface of the roller 3. The positioning rod 42 is fixedly connected to the inside of the connecting frame 2. The limiting ring 41 is slidably connected to the surface of the positioning rod 42. A left - right threaded rod 44 is rotatably connected to the inside of the connecting frame 2. A nut 43 is fixedly connected to the surface of the limiting ring 41. The left - right threaded rod 44 is rotatably connected to the inner wall of the limiting ring 41.

[0025] Specifically, the left - right threaded rod 44 is in threaded connection with the inside of the nut 43. One end of the left - right threaded rod 44 is fixedly connected to a connection cap 45.

[0026] In this embodiment: By setting the left - right threaded rod 44, the nut 43 can be moved, reducing the situation that when the device is in use, it is difficult for the limiting ring 41 to move, resulting in the difficulty of the limiting ring 41 to limit the material.

[0027] Specifically, one end of the left - right threaded rod 44 is fixedly connected to a connection head 48. A motor 46 is fixedly connected to the surface of the connection head 48. By setting the motor 46, it is convenient to rotate the left - right threaded rod 44.

[0028] Specifically, a base 47 is fixedly connected to the surface of the motor 46. The base 47 is fixedly connected to the surface of the connecting frame 2. By setting the base 47, it is convenient to limit the motor 46.

[0029] In this implementation: A cleaning device 5 is arranged on the side of the connecting frame 2. The cleaning device 5 includes a cleaning plate 52 and a connecting block 51. The connecting block 51 is fixedly connected to the side of the connecting frame 2. The cleaning plate 52 is arranged on the side of the roller 3. A positioning block 53 is fixedly connected to the surface of the connecting block 51. The cleaning plate 52 is arranged on the surface of the positioning block 53. A sliding hole 54 is formed in the surface of the positioning block 53. A clamping plate 55 is slidably connected to the inner wall of the sliding hole 54.

[0030] In this embodiment: By setting the cleaning plate 52, the surface of the roller 3 can be cleaned, reducing the situation that when the device is in use, foreign objects are easily adsorbed on the surface of the roller 3, resulting in material contamination.

[0031] Specifically, one end of the clamping plate 55 is fixedly connected to a spring 56. The end of the spring 56 away from the clamping plate 55 is fixedly connected to the inner wall of the sliding hole 54. By setting the spring 56, it is convenient to apply a reset elastic force to the clamping plate 55.

[0032] Specifically, a slider 57 is fixedly connected to the surface of the clamping plate 55. The slider 57 is slidably connected to the inside of the sliding hole 54. By setting the slider 57, it is convenient to move the cleaning plate.

[0033] Working principle: When the device is in use, the user places and moves the protective film coating on the surface of the roller 3 to support the protective film coating. When the device is in use, the user starts the motor 46. Then, when the motor 46 rotates, it drives the left - right threaded rod 44 to rotate. Then, when the left - right threaded rod 44 rotates, it drives the nut 43 to move. Then, the movement of the nut 43 drives the limit ring 41 to move on the surface of the positioning rod 42. By setting the limiting device 4, the protective film coating is effectively limited, playing a role in limiting the movement of the protective film coating with different widths. When the device is in use, when the protective film coating moves on the surface of the roller 3, it is prone to deviation, causing the protective film coating to twist and move on the surface of the roller 3, resulting in damage to the protective film coating. This improves the practicality of the device.

[0034] When the device is in use, the user slides the slider 57. Then, when the slider 57 moves, it drives the clamping plate 55 to move. When the clamping plate 55 moves, it drives the spring 56 to displace and deform to generate elastic force. Then, the clamping plate 55 moves away from the surface of the cleaning plate 52. Then, the cleaning plate 52 loses its restraint and is pulled away from the surface of the positioning block 53. By setting the cleaning device 5, the surface of the roller 3 is effectively cleaned, playing a role in cleaning the surface of the roller 3. When the device is in use, the surface of the roller 3 is prone to adsorbing dust or debris. When the roller 3 jacks up and levels the protective film coating, the dust is likely to contaminate the protective film coating, resulting in defective products of the protective film coating. This improves the practicality of the device.
