[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 4 As shown, the utility model provides a rewinding device for the production of plastic protective film, including an operating frame 1, a winding roller 2 and a guide block 3. The front side of the top of the inner wall of the operating frame 1 is movably connected to the two sides of the winding roller 2 through an axle pin, and the rear side of the top of the inner wall of the operating frame 1 is fixedly connected to the outer side of the guide block 3. Both sides of the top of the operating frame 1 are fixedly connected to a support frame 4, and the top of the inner wall of the support frame 4 is inlaid with a cylinder 5. The output end of the cylinder 5 is fixedly connected to a connecting block 6, and both sides of the connecting block 6 are movably connected to a connecting rod 7. The bottom of the inner side of the connecting rod 7 is movably connected to a pressure roller 8 through an axle pin. A moving component 9 is provided on the inner side of the connecting rod 7, and a limiting component 10 is provided on the inner side of the top of the connecting rod 7.

[0024] refer to Figure 3 The moving component 9 includes a moving groove 91, which is opened on the inner side of the connecting rod 7. The inner wall of the moving groove 91 is slidably connected to a moving block 92, and the inner side of the moving block 92 is fixedly connected to both sides of the connecting block 6.

[0025] As a technical optimization solution of the present invention, by setting a moving component 9, when the user needs to connect the connecting rod 7 with the connecting block 6, first align the connecting blocks 6 on both sides of the connecting block 6 with the moving groove 91 on the inner side of the top of the connecting rod 7, and then move the connecting rod 7 upward to move the moving block 92 to the inside of the moving groove 91. When the pressure roller 8 contacts the winding roller 2, the pressure roller 8 will move upward as the diameter of the winding roller 2 increases. Since the upward movement of the pressure roller 8 will drive the connecting rod 7 to move, it is convenient to move the moving block 92 upward inside the moving groove 91. The moving groove 91 can be used to limit the moving direction of the moving block 92, so that the up and down movement of the connecting rod 7 is more stable, thereby achieving the effect of assisting the pressure roller 8 to move up and down.

[0026] refer to Figure 4 The limiting assembly 10 includes a limiting groove 101, which is opened on the inner side of the top of the connecting rod 7. The inner wall of the limiting groove 101 is slidably connected to the limiting plate 102, and the limiting groove 101 is connected to the movable groove 91.

[0027] As a technical optimization solution of the present invention, by setting a limit assembly 10, when the user moves the moving block 92 completely to the inside of the moving groove 91, the limit plate 102 is moved toward the connecting block 6 until the inner side of the limit plate 102 contacts the inner wall of the moving groove 91. At this time, the limit plate 102 will cover the top of the moving groove 91, so that the moving block 92 cannot move out of the moving groove 91, thereby avoiding the situation where the moving block 92 automatically moves out of the moving groove 91 due to the weight of the pressure roller 8, thereby achieving the effect of limiting the moving block 92 from sliding out of the moving groove 91.

[0028] refer to Figure 4 The outer sides of the inner wall of the limiting groove 101 are provided with a card slot 11, the inner side of the card slot (1) is slidably connected with a card block 12, and the inner side of the card block 12 is fixedly connected to the two sides of the limiting plate 102.

[0029] As a technical optimization solution of the present invention, by setting the card slot 11 and the card block 12, when the limit plate 102 moves toward the connecting block 6, the limit plate 102 will drive the card block 12 to slide inside the card slot 11. The card slot 11 can be used to limit the moving direction of the card block 12, so that the limit plate 102 cannot move out of the limit slot 101, avoiding the situation that the limit slot 101 automatically detaches from the limit slot 101 due to the lack of a device to limit the movement of the limit plate 102, thereby achieving the effect of auxiliary use of the limit plate 102.

[0030] refer to Figure 3A rebound groove 13 is provided on the outer side of the inner wall of the movable groove 91, and a spring 14 is fixedly connected to the bottom of the inner wall of the rebound groove 13. A pressure plate 15 is slidably connected to the top of the inner wall of the rebound groove 13. The inner side of the surface of the pressure plate 15 is slidably connected to the inner wall of the movable groove 91, and the bottom of the pressure plate 15 is fixedly connected to one end of the spring 14 close to the limit plate 102.

[0031] As a technical optimization solution of the present invention, by setting a rebound groove 13, a spring 14 and a pressure plate 15, when the connecting block 6 moves to the inside of the movable groove 91, the bottom of the movable block 92 will contact the inner side of the top of the pressure plate 15, and as the movable block 92 moves downward, the movable block 92 will drive the pressure plate 15 to move downward. The movement of the pressure plate 15 can cause the spring 14 to be squeezed and contracted. As the diameter of the winding roller 2 increases, the spring 14 slowly contracts, so that the pressure roller 8 always has a relatively balanced pressure to squeeze the winding roller 2, so that the leveling effect of the pressure roller 8 is better, thereby achieving the effect of assisting the leveling of the pressure roller 8.

[0032] refer to Figure 3 The bottom of the inner wall of the rebound groove 13 is fixedly connected with an auxiliary rod 16 , the spring 14 is movably sleeved on the surface of the auxiliary rod 16 , and the inner wall of the pressure plate 15 is slidably connected to the surface of the auxiliary rod 16 .

[0033] As a technical optimization solution of the present invention, by setting an auxiliary rod 16, when the pressure plate 15 moves downward, the auxiliary rod 16 can limit the moving direction of the pressure plate 15, making the movement of the pressure plate 15 more stable. At the same time, the auxiliary rod 16 can limit the contraction direction of the spring 14 to avoid the twisting of the spring 14, making the movement of the connecting rod 7 more stable, thereby achieving the effect of assisting the contraction of the spring 14.

[0034] refer to Figure 2 and Figure 4 The top of the limiting plate 102 and the bottom of the inner wall of the limiting groove 101 are both provided with reinforcement grooves 17, and the inner wall of the reinforcement groove 17 is slidably connected with a reinforcement rod 18. The top of the connecting rod 7 is provided with a placement groove 19, and there are several placement grooves 19 at equal distances. The inner wall of the placement groove 19 is slidably connected to the bottom surface of the reinforcement rod 18.

[0035] As a technical optimization solution of the present invention, by setting a reinforcement groove 17, a reinforcement rod 18 and a placement groove 19, when the user brings the inner side of the limit plate 102 into contact with the inner wall of the movable groove 91, the reinforcement groove 17 at the top of the limit plate 102 is connected to the reinforcement groove 17 at the bottom of the inner wall of the limit groove 101, and then the reinforcement rod 18 is taken out from the placement groove 19, and the bottom of the reinforcement rod 18 is aligned with the reinforcement groove 17, and then the reinforcement rod 18 is moved downward. The reinforcement rod 18 can be used to connect the limit plate 102 and the connecting rod 7 together, so that the limit plate 102 cannot move left and right, and then the placement groove 19 can be used to facilitate the user to place the reinforcement rod 18, thereby achieving the effect of limiting the movement of the limit plate 102.

[0036] The working principle and usage process of the present invention are as follows: when in use, the support frame 4 can be used to facilitate the user to install the pressure roller 8 on the top of the winding roller 2, and then the cylinder 5 can be used to drive the pressure roller 8 to move up and down, thereby further leveling the protective film. When the user needs to connect the connecting rod 7 with the connecting block 6, first align the connecting blocks 6 on both sides of the connecting block 6 with the movable groove 91 on the inner side of the top of the connecting rod 7, and then move the connecting rod 7 upward to make the movable block 92 move to the inside of the movable groove 91. When the pressure roller 8 contacts the winding roller 2, the pressure roller 8 will move upward as the diameter of the winding roller 2 increases. Since the pressure roller 8 moves upward, it will drive the connecting rod 7 to move, which makes it convenient for the movable block 92 to move upward inside the movable groove 91. The movable groove 91 can be used to limit the moving direction of the movable block 92, making the up and down movement of the connecting rod 7 more stable. When the user moves the movable block 92 completely to When the cam 102 is in contact with the inner wall of the cam 102, the cam 102 will move upwards to prevent the cam 102 from moving out of the cam 102 and the cam 102 from moving out of the cam 102.

[0037] To sum up: the rewinding device for the production of plastic protective film is provided with a support frame 4, a cylinder 5 and a pressure roller 8. The support frame 4 can be used to facilitate the user to install the pressure roller 8 on the top of the winding roller 2, and then the cylinder 5 can be used to drive the pressure roller 8 to move up and down, thereby further flattening the protective film, solving the problem that the protective film rewinding device is not provided with a device to assist in flattening the protective film. When the protective film is rolled up, the protective film is prone to uneven rolling, which affects the appearance of the protective film after it is rolled up, thereby reducing the problem of the yield rate.
