Description

Technical Field

[0001] The utility model relates to the technical field of PET substrate coating release films, in particular to a PET release film coating machine. Background Art

[0002] PET release film coating machine is used to coat PET (polyethylene terephthalate) release film. It is used in plastics, review materials, electronic components and other industries. Its main function is to coat a layer of release film on the PET substrate to improve the surface properties of the PET substrate. Usually, the coating method for PET substrates requires manual intervention and operation, and cannot meet the different requirements of different models of PET substrates. The distance and fixation between multiple winding rollers, shaping rollers and extrusion rollers are fixed.

[0003] The positions of the winding roller, the shaping roller and the squeezing roller of the existing PET release film coating machine are fixed. For example, a PET release film coating machine disclosed in application number CN220277422U includes a telescopic rod seat, a base frame, a shell and a coating roller. The base frame is fixed to the lower end of the shell, the telescopic rod seat is arranged at the upper end inside the shell, the lower end of the telescopic rod seat is internally slidably connected with a movable rod, and a spring is arranged on the movable rod, the lower end of the spring is fixed with a stretching seat, and the lower end of the stretching seat is equipped with a wheel, the coating roller is arranged at the side end of the movable rod, and the coating roller is fixed at the side end of the movable rod. A heating layer is provided inside the coating roller at the lower part of the telescopic rod seat, and the heating layer is fixedly connected to a heating rod, and an insulating layer is provided on the inner wall of the heating layer. This scheme presses and flattens the material and the mold, and the coating is uniform. When coating, the film is heated, and the coating effect is good. However, it cannot adapt to the coating of materials of different lengths. The coating of a shorter distance may be rolled up before being heated, and the material of a longer distance may be rolled up before being heated evenly. The distance between the winding roller and the shaping roller cannot be flexibly moved and adjusted, and the demand for flexible adjustment of the path for materials of different lengths cannot be met.

[0004] Therefore, it is necessary to invent a PET release film coating machine to solve the above problems. Utility Model Content

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model provides Figure 1-3 A PET release film coating machine shown in the figure includes a coating machine body 1, a first winding roller 4, a mounting plate 5 and a second winding roller 6. A motor 2 is installed on the coating machine body 1, and a synchronous belt mechanism 201 is connected to the motor 2. The synchronous belt mechanism 201 drives the PET substrate starting end 3, the first winding roller 4 and the release film box 8 respectively. The release film box 8 can install multiple release film rollers. The coating machine body 1 is fixedly connected to the mounting plate 5, and a through hole is provided on the mounting plate 5. A fixing part 7 and a movable roller 10 can be inserted into the through hole. The fixing part 7 is used to fix the two winding rollers 6 after winding is completed, and the movable roller 10 is used to flexibly adjust the path of the PET substrate.

[0024] After the PET substrate passes through the surfaces of multiple active rollers 10 in sequence, it passes through the coating film in the release film box 8 and is finally collected on the first winding roller 4 or the second winding roller 6. The entire coating path is diversified and can simultaneously meet the coating needs of two sets of PET substrates.

[0025] The mounting plate 5 is fixedly connected to a slide groove 13, and a plurality of positioning holes are provided on the slide groove 13, into which a slider 12 can be inserted, and the slider 12 is fixedly connected to a movable roller 11, and a plurality of movable rollers 10 are provided, and the plurality of movable rollers 10 can be inserted into the through holes in the mounting plate 5, and fixed on the back side of the mounting plate 5 by bolts.

[0026] A plurality of movable rollers 10 can be flexibly installed on the mounting plate 5 by plugging and unplugging, which can realize the travel paths of various films, better meet the coating needs of large and small film rollers, and the whole process has a high degree of automation.

[0027] A PET substrate roller is installed in the starting end 3 of the PET substrate. The PET substrate passes through multiple active rollers 10 in sequence and passes between the release films in the release film box 8. The end is rolled up and fixed on the second winding roller 6. The release film roller in the release film box 8 is clamped between the two rollers. The rotation of the release film roller is driven by the motor 2. The movable roller 11 can move up and down through three gears. The diameter of the movable roller 11 and the active roller 10 is the same.

[0028] The movable roller 11 can be positioned in three gears to achieve coating of a small amount of PET substrate, so that the path of the PET substrate passing through the roller is the shortest, and the PET substrate is directly rolled up after being directly coated.

[0029] Working principle of this utility model:

[0030] Refer to the instruction manual Figure 1-3 When using the utility model, first fix the starting end of the PET substrate to the starting end 3 of the PET substrate, or install the PET substrate roll into the starting end 3 of the PET substrate, take out the end, and pass through the following in sequence: Figure 1 The method shown is fixed to the second winding roller 6 after passing through the release film box 8, and the surface is coated with the release film and then rolled onto the second winding roller 6. When the second winding roller 6 needs to be removed, the fixing member 7 needs to be pulled out;

[0031] Refer to the instruction manual Figure 3-5 When using the utility model, by Figure 3 Another method shown is that the PET substrate passes through in sequence, passing through the surface of the moving roller 11, and is directly transported to the release film box 8 to be collected by the second winding roller 6. The path is the shortest and the coating process with a small amount of PET substrate is relatively small.

[0032] The movable roller 11 can move up and down in three gears to better meet the coating processing of a small amount of PET substrates, and multiple movable rollers 10 can be movably plugged in and out and moved on the mounting plate 5 to simultaneously meet the coating of two sets of PET substrates (the end is fixed on the first winding roller 4 and the end is fixed on the second winding roller 6).
