Description

Technical Field

[0001] The utility model relates to the field of diaphragms, in particular to a film composite film. Background Art

[0002] During the production process, the diaphragm is generally produced through steps such as high-pressure cutting. It is usually necessary to ensure the cleanliness of the diaphragm surface before and after production. The solution of the prior art is generally to use transfer equipment (such as various storage devices for temporary storage), that is, all the diaphragms are temporarily placed in the equipment, and then transferred, and the unloading, sorting and loading operations are performed at the construction location. However, this operation mainly relies on manual labor. After the transfer, the stacked diaphragms need to be sorted and loaded manually, which greatly increases the labor consumption and cannot meet the needs of automated production. In addition, manual handling can easily cause the diaphragm to be contaminated when it is taken out of the storage device, and it is easy to cause the diaphragm to be damaged before processing. Utility Model Content

A sealing strip is arranged in the recess, and the sealing strip is attached to the end gap of the film body.

[0008] As an improvement of the above technical solution, the sealing strip is made of a water-soluble material.

[0009] As an improvement of the above technical solution, the coating film 1 and / or coating film 2 is a release film.

[0010] Beneficial effects of the utility model:

[0011] The outer protective film is formed by the coating 1 and the coating 2. The protective film is used to protect the surface of the film, and the adhesive strip is used between the coating 1 and the coating 2 for bonding and protection. The protective film is torn off through the side cavity, which can be synchronized with the mechanical structure, and the protective film is also provided on the outer side for protection in case of manual operation, which effectively avoids the problem of the operator directly contacting the film body, and can not only provide protection effect for the film body, but also meet the use requirements of automated production.

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] The method for solving the problem of diaphragm transfer in the prior art is generally to use transfer equipment (such as various storage devices for temporary storage), that is, all diaphragms are temporarily placed in the equipment, and then transferred, and unloading, sorting and loading operations are performed at the construction location. However, this operation mainly relies on manual labor. After the transfer, the stacked diaphragms need to be sorted and loaded manually, which greatly increases the labor consumption and cannot meet the needs of automated production. In addition, manual handling can easily cause the diaphragms to be contaminated when they are taken out of the storage device, and can easily cause the diaphragms to be damaged before processing.

[0019] In one embodiment, see Figures 1 to 4 , a film composite film, including: a film body 10.

[0020] Specifically, the diaphragm body 10 includes a coating 11, a coating 2 12 and a film body 13. At least two groups of rubber strips 111 are arranged on one side end face of the coating 11. The film body 13 is arranged between the two groups of rubber strips 111. The coating 2 12 and the coating 1 11 are detachably bonded by the rubber strips 111. A side cavity 14 is provided at the connection between the rubber strips 111 and the coating 2 12.

[0021] The adhesive strip 111 is used to adhere the coating 11 and the coating 2 12, thus forming a state of covering all around, and then the side cavity 14 is set to cooperate with the inserting device to tear the adhesion relationship between the coating 11 and the coating 2 12. In this way, when separating, at least two limit members are inserted from the side cavity 14, one of which is used to limit the position of the coating 11, and the other limit member is moved upward by pulling, so that the upper covering coating 2 12 will be torn off the coating 11, thereby exposing the internal film body 13. This structure is not only convenient for transportation and provides protection during transportation, but also can cooperate with the mechanical structure to meet the needs of automated production.

[0022] In order to reduce the contact between the film body 13 and the adhesive strip 111, please refer to Figure 3 and Figure 4 The two sides of the second film 12 have at least two groups of protrusions 121, and a bottom cavity 122 is opened on the side of the protrusion 121 close to the first film 11. The rubber strip 111 is arranged inside the bottom cavity 122, and the two sides of the film body 13 are attached to the protrusions 121.

[0023] A U-shaped recessed structure is formed by the protrusion 121. Under this structure, the film body 13 will contact the inner wall of the protrusion 121. It is only necessary to set the adhesive strip 111 for bonding inside the bottom cavity 122 of the protrusion 121 to avoid contact between the film body 13 and the adhesive strip 111, thereby ensuring that the film body 13 is protected from contamination by the adhesive strip 111.

[0024] In addition, in order to ensure the adhesion of the adhesive strip 111 and reduce the difficulty of tearing, please refer to Figure 2 , Figure 3 and Figure 4 There are at least four rubber strips 111, and every two rubber strips 111 form a group. The side cavity 14 is formed by separating the two rubber strips 111, the protrusion 121 and the coating 1 11. A notch 113 is formed between the two protrusions 121, the coating 12 and the coating 1 11. A sealing strip 112 is arranged in the notch 113, and the sealing strip 112 is attached to the end gap of the film body 13.

[0025] At least two groups of side cavities 14 are formed by forming two rubber strips 111 into a group. Thus, when pulling, the center position of the rubber strip 111 can be pulled stably without the problem of force deviation, thereby ensuring accuracy during the pulling process.

[0026] In one embodiment, see Figure 2 and Figure 3 The sealing strip 112 is made of water-soluble material.

[0027] When the film body 13 is processed, in order to avoid the influence of the sealing strip 112, the sealing strip 112 is dissolved in a water bath, so that the sealing strip 112 can ensure the protection function of the film body 13 before processing and avoid the influence on the processing process.

[0028] In addition, in order to prevent the torn film from having excessive adhesion, specifically, the first covering film 11 and / or the second covering film 12 is a release film.

[0029] It is only necessary to ensure that there is at least one release film between the first film 11 and the second film 12 to ensure that there is no strong adhesion after the film is torn off, thereby facilitating subsequent cleaning work.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
