Description

Technical Field

[0001] The utility model mainly relates to the technical field of production and processing of protective films, in particular to a protective film winding pressure adjustment device. Background Art

[0002] The protective film winding pressure adjustment device is a key part of the protective film winding equipment. Its main function is to adjust the pressure on the protective film during the winding process to avoid damage to the protective film due to excessive pressure or loose winding due to insufficient pressure. By adjusting the pressure, it can ensure that the protective film remains flat and tight during the winding process, thereby improving the winding quality.

[0003] According to the application number CN202320973236.8, a film tension adjustment structure is provided, including a shell and a limit rod, with adjustment rods hinged on both sides of the shell, and a rotatable tension roller is connected between the two adjustment rods. The adjustment rod includes avoidance holes with open upper and lower ends, and the limit rod is located on both sides of the shell. The limit rod passes through the corresponding avoidance holes, and the outer side of the limit rod is threadedly connected with a first buffer block and a second buffer block. The adjustment rod is located between the first buffer block and the second buffer block. The adjustment rod can swing between the first buffer block and the second buffer block with the hinge point with the shell as the center of the circle. By twisting the first buffer block and the second buffer block, the position height of the tension roller can be adjusted.

[0004] The adjustment implementation of the above-mentioned structural device is relatively complicated. The tension adjustment range is limited during the actual processing process, which may cause deviations. Especially in long-term processing, it is necessary to stop and adjust the film winding from time to time, which is troublesome to operate and daily maintenance. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] Example

[0026] like Figures 1 to 4 As shown, it includes a workbench 10 and a support plate 20 provided on one side of the workbench 10. A first adjusting roller 11 is provided at one end of the top of the workbench 10. A fixed support roller 12 is provided at one end of the first adjusting roller 11 and located at the top of the workbench 10. A second adjusting roller 13 is provided at one end of the fixed support roller 12 and located at the top of the workbench 10.

[0027] Sliding grooves 21 are symmetrically provided at both ends of the top of the support plate 20, and a moving slider 22 is slidably connected to the inner wall of the sliding groove 21. A double-threaded rod 23 is provided on one side of the top of the support plate 20 located on one side of the workbench 10, and a motor drive part 24 is provided on the other side of the top of the support plate 20.

[0028] A limiting block 221 is provided at one end of the bottom of the movable slider 22 , and a limiting hole 222 is provided at the bottom of one side of the movable slider 22 .

[0029] The outer wall of the double-threaded rod 23 is sleeved with a gear 1 231 .

[0030] A second gear 241 is provided at one end of the motor drive member 24, and a motor 242 is provided at the other end of the motor drive member 24;

[0031] Gear 2 241 meshes with gear 1 231 .

[0032] Both ends of the first adjusting roller shaft 11 are sleeved on the top inner wall of the movable slider 22 .

[0033] The two ends of the outer wall of the double-threaded rod 23 are threadedly connected to the limiting hole 222.

[0034] The limiting block 221 is embedded in one end of the inner wall of the sliding groove 21 .

[0035] It needs to be explained that in the embodiment, the protective film is input from the input end of the workbench 10, passes through the outer wall bottom of the first adjusting roller shaft 11, and then passes through the three fixed support roller shafts 12 in turn from the top bottom, and then passes through the outer wall bottom of the second adjusting roller shaft 13 from the output end of the workbench 10. During the winding process, the pressure monitoring sensor is arranged to monitor the winding of the protective film in real time. When the pressure is larger than the threshold value, the motor 242 at one end of the motor drive 24 works, drives the gear two 241 at the other end of the motor drive 24 to rotate forward, the gear one 231 meshed with the gear two 241 is reversely rotated and drives the double threaded rod 23 to reversely rotate, and the moving block 22 threadedly connected at both ends of the double threaded rod 23 is away from the moving block 22, and the first adjusting roller shaft 11 and the second adjusting roller shaft 13 sleeved on the moving block 22 are also away from the moving block 22, so as to reduce the pressure in the winding process of the protective film. On the contrary, when the pressure is smaller than the threshold value, the motor 242 drives the gear two 241 to reversely rotate, the double threaded rod 23 is driven to rotate forward and drives the moving block 22 to approach, and then the first adjusting roller shaft 11 and the second adjusting roller shaft 13 approach, so as to increase the pressure in the winding process of the protective film. In addition, in the process, the sliding groove 21 at both ends of the top of the supporting plate 20 limits the moving position of the moving block 22, the limiting block 221 at one end of the bottom of the moving block 22 is embedded in the inner wall of the sliding groove 21, and the moving block 22 can be limited to prevent the moving block 22 from falling off during the sliding process.

[0036] The working principle of the utility model is:

[0037] When the pressure monitoring sensor monitors that the pressure threshold value is too large, the motor 242 gear two 241 rotates forward, the gear one 231 meshed with the gear two 241 reversely rotates and drives the double threaded rod 23 to reversely rotate, and the moving block 22 threadedly connected at both ends of the double threaded rod 23 is away from the moving block 22, and the first adjusting roller shaft 11 and the second adjusting roller shaft 13 sleeved on the moving block 22 are also away from the moving block 22, so as to reduce the pressure in the winding process of the protective film. On the contrary, when the pressure is smaller than the threshold value, the motor 242 drives the gear two 241 to reversely rotate, the double threaded rod 23 is driven to rotate forward and drives the moving block 22 to approach, and then the first adjusting roller shaft 11 and the second adjusting roller shaft 13 approach, so as to increase the pressure in the winding process of the protective film.

[0038] The above embodiment is only for illustrating the technical idea of the utility model, and cannot limit the protection scope of the utility model. Any modification made on the basis of the technical scheme according to the technical idea of the utility model falls within the protection scope of the utility model.
