Description

Technical Field

[0001] The utility model relates to the technical field of protective films, in particular to a protective film rewinding tension control device. Background Art

[0002] PE protective film is the simplest macromolecular organic compound and the most widely used macromolecular material in the world today. PE protective film uses special polyethylene (PE) plastic film as the base material and is divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to different densities. The protective film is a layer of plastic film that protects the product. It is often compounded with coiled materials to make the surface of the coiled materials not easily scratched.

[0003] After the production of the protective film is completed, it is generally necessary to roll it up for subsequent use. However, when the protective film is rolled up, it is inevitable that it will become loose, which can easily lead to uneven rolling. Moreover, when the rolling device is in operation, since there is no static electricity removal device, the static electricity carried by the protective film will interfere with the rolling process, which can easily lead to the deviation of the protective film and the unsatisfactory fit of the protective film after rolling, affecting the yield rate of the protective film rolling.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 As shown, a protective film rewinding tension control device includes a base plate 1, and also includes: connecting plates 2 arranged on both sides of the top of the base plate 1, guide rollers 3 are arranged between the opposite sides of the two connecting plates 2, and the front and rear sides of the right side of the top of the base plate 1 are fixedly connected to support plates 4; a first motor 5 is arranged on the front side of the support plate 4, and the output end of the first motor 5 passes through the rear side of the support plate 4 and is fixedly connected to a winding roller 6; a fixed shell 7 is arranged on the rear side of the top of the base plate 1, and the top of the fixed shell 7 is fixedly connected to a drive component 8, and the rear side of the fixed shell 7 is fixedly connected to a controller 9.

[0021] refer to Figure 2 , Figure 3 and Figure 4 As shown, reinforcement blocks 10 are fixedly connected to both sides of the fixed shell 7, the bottom of the reinforcement block 10 is fixedly connected to the base plate 1, an outer shell 11 is provided on the top of the base plate 1, and the inner cavities on the opposite sides of the two outer shells 11 are fixedly connected to ion fans 12, and the outer shell 11 is fixed between the two fixed plates 804.

[0022] It should be noted that the fixed connection between the reinforcement block 10 and the base plate 1 serves to reinforce the fixed shell 7. The coordinated use of the outer shell 11 and the ion blower 12 can remove static electricity on the protective film to ensure the fit of the protective film during subsequent winding action.

[0023] refer to Figure 1 , Figure 2 and Figure 3 As shown, the driving assembly 8 includes a second motor 801, the output end of the second motor 801 passes through the inner cavity of the fixed shell 7 and is fixedly connected to a screw rod 802, the surface of the screw rod 802 is sleeved with a threaded sleeve 803, and a fixed plate 804 is arranged on the front side of the threaded sleeve 803, and a limiting roller 805 is arranged between the opposite sides of the two fixed plates 804, the rear side of one of the fixed plates 804 is fixedly connected to the threaded sleeve 803, and sliders 806 are fixedly connected on both sides of the threaded sleeve 803, and slide grooves 807 used to cooperate with the sliders 806 are provided on both sides of the inner cavity of the fixed shell 7, a reinforcement ring 808 is fixedly connected to the bottom of the second motor 801, and the bottom of the reinforcement ring 808 is fixedly connected to the fixed shell 7, and a sliding block 809 is fixedly connected to the front side of the fixed plate 804, and a sliding rod 810 is arranged in the inner cavity of the sliding block 809, and the bottom of the sliding rod 810 is fixedly connected to the bottom plate 1.

[0024] It should be noted that: the screw rod 802 is rotated by driving the second motor 801. When the screw rod 802 rotates, the threaded sleeve 803 drives the slider 806 to move in the inner cavity of the slide groove 807, and at the same time drives the fixed plate 804 to move. At this time, one of the fixed plates 804 drives the sliding block 809 to assist in rising on the surface of the slide rod 810. As the fixed plate 804 moves, the limiting roller 805 is lifted up, thereby tightening the protective film. The second motor 801 is reinforced through the fixed connection between the reinforcement ring 808 and the fixed shell 7.

[0025] Working principle: First, the protective film is rolled up on the surface of the winding roller 6 through the guide roller 3 and the limiting roller 805, and the protective film is rolled up as the first motor 5 is driven. During the rolling process, the upper and lower surfaces of the protective film can be synchronously sprayed and cleaned by driving the ion fan 12, and the free static electricity on the surface of the protective film can be cleaned, thereby ensuring the fit of the protective film during subsequent rolling actions. When the protective film is loose, the screw rod 802 can be rotated by driving the second motor 801. When the screw rod 802 rotates, the threaded sleeve 803 drives the slider 806 to move in the inner cavity of the slide groove 807, and drives the fixed plate 804 to move at the same time. At this time, one of the fixed plates 804 drives the sliding block 809 to assist in rising on the surface of the slide rod 810, and as the fixed plate 804 moves, the limiting roller 805 is driven to rise, thereby tensioning the protective film.
