Description

Technical Field

[0001] The utility model relates to the technical field of thin films, in particular to a thin film layering tool. Background Art

[0002] During the film blowing process, the film needs to be corona treated, that is, high frequency and high voltage are used to discharge corona on the surface of the polymer material to generate low-temperature plasma, and free radicals are generated on the plastic surface to cause the polymer to undergo cross-linking reaction, making the surface rough and increasing its wettability to polar solvents. These plasmas enter the surface of the film by electric shock and penetration, destroying the polymer structure, oxidizing and polarizing the treated surface molecules, and ion electric shock eroding the surface, thereby increasing the adhesion ability of the film surface. However, there are also certain side effects, that is, the corona surface is prone to adhesion in a high temperature and high humidity environment, that is, the roughened film surface is prone to vacuum adsorption under pressure, and it is difficult to separate after the subsequent winding is completed. Utility Model Content

[0003] The utility model aims to solve the above technical problems and provide a film layering tool which can separate the film during winding so as to reduce the adhesion of the film.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Embodiment 1

[0022] like Figure 1-5 As shown, a film layering tool comprises a long strip insert 1, one end of which is connected to a fixing device 16 capable of fixing the insert 1 on a winder railing 17, a hollow cavity 2 is provided inside the insert 1, that is, the insert 1 is hollow inside, and a plurality of air outlets 3 connected to the hollow cavity are provided on both sides of the insert 1 along the width direction, and the directions of the left and right sides are based on Figure 1 Based on the difference in the placement of the insert 1, the insert 1 is provided with an air inlet 4 at the same end where the fixing device 16 is provided, and is specifically provided on the right side of the fixing device 16. The right side here is the same as above. Figure 1 On the basis of this, in addition, preferably, the air inlet 4 is arranged on the side close to the film 19 after it is separated, because the air outlet is large on the side close to the air inlet, so that the newly separated film 19 can be replenished with air, so that a certain amount of air can be retained between the separated films 19, so that the customer can better separate the film 19 during subsequent use. The air inlet 4 is connected to the air pipe 5, and the air pipe 5 is connected to the inflation device (not shown in the figure). The inflation device here can be any device, which is not limited in the utility model.

[0023] like Figure 3 As shown, in order to prevent damage to the surface of the film, a further preferred technical solution is that the cross section of the insert 1 along the width direction is a capsule shape, and the two sides of the capsule shape have arcs. Compared with the rectangular cross section, the arcs will not scratch the surface of the film, thereby ensuring the quality of the finished film. In order to prevent scratches on the surface of the film, a further preferred technical solution is that a smooth arc-shaped insert head 6 is provided at one end of the insert 1 away from the fixing device 16. This is to prevent the insert from being too sharp when the insert is inserted. The insert head is therefore also selected to be smooth and arc-shaped.

[0024] In order to be able to fix the tooling on the railing of the winder, a further preferred technical solution is that a mounting plate 7 is provided at one end of the insert 1, and two first mounting holes 8 are provided on the mounting plate 7, and the fixing device 16 includes two mutually compatible fixing half rings 9, and the fixing half rings 9 are fixedly connected with a first mounting plate 10 at the top and bottom, and the first mounting plate 10 has two second mounting holes 11, and one side of the first mounting plate 10 of one fixing half ring 9 is fixedly connected with a second mounting plate 12, and the fixing half ring 9 selected here is close to the insert 1 during installation, and the second mounting plate 12 is provided with a third mounting hole 13 compatible with the first mounting hole 8, and a ring is formed by the cooperation of the two fixing half rings, and the tooling is sleeved on the railing, and the mounting holes here are spirally connected by screws, and when the sizes of the railings are different, the screws can be removed to adjust the spacing between the two fixing half rings, which has strong applicability.

[0025] Example 2

[0026] like Figure 6 As shown, the difference between this embodiment and embodiment 1 is that, in order to improve the utilization efficiency of the gas, a further preferred technical solution is that an air intake main pipe 14 is provided inside the insert 1, and a plurality of air intake branch pipes 15 are provided on both sides of the air intake main pipe 14, and the air intake branch pipes 15 are connected to the air intake hole 4, so that the air filled into the inflation device is directly discharged from the air intake hole 4 and will not be retained in the hollow cavity 2.

[0027] Example 3

[0028] like Figure 1 As shown, the difference between this embodiment and embodiment 1 is that, since the fixing device is fixed by threaded connection, in order to adjust the angle of the insert without removing the fixing device, a further preferred technical solution is that the insert 1 is connected to the fixing device 16 by an adjustment structure. A connecting column 20 is provided at one end of the insert 1, and the adjustment structure includes a joint bearing 21 and a bearing seat 22 for mounting the joint bearing 21. The connecting column 20 is connected to the joint bearing 21, and the other end of the bearing seat 22 is provided with a mounting plate 7 for mounting the fixing device 16. The fixing device on the mounting plate is the same as that in embodiment 1. By utilizing the characteristics of the joint bearing, the angle of the insert is adjusted without removing the fixing device. In addition, the joint device can also adjust the pitch angle of the insert based on the z-axis, thereby improving the applicability of the device.

[0029] The working principle of the utility model is as follows: Figure 5 As shown, insert pieces 1 are installed on both sides of the railing 17 through fixing devices 16, and the insert pieces 1 are inserted into the film 19. The inflation device is turned on to eject air from the air outlet 3. The film 19 is separated into two layers as the winding and transporting roller 18 moves. The air left between the layers can facilitate the customer to separate the film after folding.

[0030] The utility model provides a long strip of inserting piece, which is inserted into the unbonded film after corona and before rolling to perform layering, and at the same time, gas is sprayed onto the film so that air exists on the surface of the film and the previously bonded film can be blown away to prevent the film from being excessively bonded after rolling. In this way, when the finished film is rolled together, a certain amount of air can be retained between the film layers, thereby reducing the effective contact area between the films, achieving the effect of preventing the films from sticking together, and making it convenient for users to separate the films.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
