Description

Technical Field

[0001] The utility model relates to the technical field of industrial wrapping film winding, and more specifically to a stress regulating device for industrial wrapping film winding. Background Art

[0002] Industrial stretch film winding is an important step in the production process. It refers to the process of winding the continuously produced film on the core shaft according to certain specifications and requirements after the process of manufacturing stretch film (also called stretch film, heat shrink film) is completed.

[0003] When the industrial wrap film is in use, the paper roll is usually installed on the winding rod, and the wrap film is then passed through the rotating roller and other guide devices in an orderly manner so that the end of the wrap film is fixed on the paper roll. Then the controller is operated to start the winding rod to rotate, thereby driving the paper roll to roll the wrap film.

[0004] In actual use of the prior art, since the tension of the stretch film during the winding process is too small, it is easy to cause the stretch film to sag during the winding process, so that the stretch film is not wound tightly and appears loose and has holes, affecting the quality of the stretch film roll. Therefore, a stress adjustment device for winding industrial stretch film is proposed. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] Example 1

[0032] Reference Figure 1 , Figure 2 and Figure 3 , which is the first embodiment of the utility model, and this embodiment provides a stress adjustment device for winding industrial wrapping film, including a winder body 1 and a connecting frame 101, the upper surface of the winder body 1 is fixedly connected with the connecting frame 101, and the upper surface of the winder body 1 is provided with a stress adjustment component 2.

[0033] Specifically, the stress adjustment component 2 includes a groove 201 opened inside the connecting frame 101, the interior of the groove 201 is fixedly connected to a motor 202, the output shaft end of the motor 202 is fixedly connected to a threaded rod 203, the outer surface of the threaded rod 203 is threadedly connected to a sleeve 204, the side of the sleeve 204 is fixedly connected to a first rotating roller 205, a slide rail 207 is opened inside the connecting frame 101, the interior of the slide rail 207 is slidably connected to a slider 208, and the side of the slider 208 is connected to the first rotating roller 205.

[0034] Furthermore, the motor 202 is started to drive the threaded rod 203 to rotate. When the threaded rod 203 rotates, it drives the sleeve 204 to move up and down along the threaded rod 203. When the sleeve 204 moves, it drives the first rotating roller 205 to move up and down. At the same time, when the first rotating roller 205 moves, it drives the slider 208 to slide in the slide rail 207, so as to support and limit the sleeve 204, and further make the first rotating roller 205 and the second rotating roller 206 reach a suitable tension for the winding film, so as to avoid the problem of looseness and voids caused by too small tension during the winding process of the winding film. Therefore, the distance between the first rotating roller 205 and the fixed second rotating roller 206 can be accurately adjusted to adapt to winding films of different thicknesses, so as to ensure that the film can always be wound evenly and tightly under suitable tension during the winding process.

[0035] Example 2

[0036] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment. A winding rod 102 is provided on the outer surface of the connecting frame 101 , and a fixing component 2 is provided inside the winding rod 102 .

[0037] Specifically, the fixing component 3 includes a fixing groove 301 opened inside the winding rod 102, a plurality of telescopic rods 302 are fixedly connected inside the fixing groove 301, a connecting block 303 is fixedly connected to the output end of the telescopic rod 302, a moving groove 304 is opened inside the winding rod 102, the outer surface of the connecting block 303 is slidably connected to the inside of the moving groove 304, an arc-shaped fixing plate 305 is fixedly connected to the side of the connecting block 303, a spring 306 is sleeved and connected to the outer surface of the telescopic rod 302, one end of the spring 306 is connected to the inside of the fixing groove 301, and the other end is connected to the connecting block 303.

[0038] Furthermore, when the arc-shaped fixing plate 305 moves, the telescopic rod 302 and the spring 306 are compressed, so that the paper roll is installed on the surface of the winding rod 102. At the same time, the elasticity of the spring 306 drives the arc-shaped fixing plate 305 to move outward so as to fix the inner wall of the paper roll, thereby being able to adapt to the fixation of paper rolls of different sizes, ensuring that the paper roll will not shake or shift during the winding process, so as to provide a stable base for the subsequent winding of the wrapping film, ensuring that the wrapping film can be evenly, tightly and flatly wound on the paper roll, thereby effectively improving the winding quality and production efficiency of the wrapping film.

[0039] Working principle: When in use, the support rod 103 on the lower surface of the winder body 1 is used to place it in the designated position. The support rod 103 can support the winder body 1, thereby improving the overall stability of the device. At this time, the staff passes the paper roll through the winding rod 102 and presses the two sets of arc-shaped fixing plates 305 on the surface of the winding rod 102 toward each other. When the arc-shaped fixing plates 305 move, the telescopic rod 302 and the spring 306 are compressed, so that the paper roll is installed on the surface of the winding rod 102. At the same time, the elasticity of the spring 306 drives the arc-shaped fixing plates 305 to move. The plate 305 moves outward to fix the inner wall of the paper roll, so that it can adapt to fix paper rolls of different sizes, ensuring that the paper roll will not shake or shift during the winding process, so as to provide a stable base for the subsequent winding of the wrapping film, ensuring that the wrapping film can be evenly, tightly and flatly wound on the paper roll, thereby effectively improving the winding quality and production efficiency of the wrapping film, and the auxiliary rod 307 near the winding rod 102 can further reinforce the paper roll from the side, especially for large diameter or heavy load paper rolls, which can prevent the paper roll from deviating from the center or fixing failure due to lateral force during the winding process.

[0040] When in use, the staff will pass the wrapping film through the first rotating roller 205, the second rotating roller 206 and the third rotating roller 105 in order to fix the end of the wrapping film on the paper roll, and then operate the controller 104 to start the motor 202 to drive the threaded rod 203 to rotate. When the threaded rod 203 rotates, it will drive the sleeve 204 to move up and down along the threaded rod 203. When the sleeve 204 moves, it will drive the first rotating roller 205 to move up and down. At the same time, when the first rotating roller 205 moves, it will drive the slider 208 to slide in the slide rail 207. In order to play a supporting and limiting role for the sleeve 204, the first rotating roller 205 and the second rotating roller 206 can further reach a suitable tension for the wrapping film, avoiding the problem of looseness and voids caused by too low tension during the winding process of the wrapping film. The distance between the first rotating roller 205 and the fixed second rotating roller 206 can be accurately adjusted to adapt to wrapping films of different thicknesses, ensuring that during the winding process, the film can always be evenly and tightly wound under suitable tension, thereby ensuring the quality of the wrapping film winding and the convenience of subsequent use.

[0041] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
