Device for preventing adhesive from being attached to compound machine for windowing composite film

Abstract

The utility model discloses a device for preventing an adhesive from being attached to a compound machine for a windowing composite film, and relates to a device for preventing the adhesive from being attached. The utility model aims to solve the problems that the performance of the windowing composite membrane is influenced and the service life of the component of the compound machine is shortened due to the fact that an adhesive is easy to adhere to the component of the solvent-free compound machine in the production process of the windowing composite membrane. The glue blocking film winding device is simple in structure, the glue blocking film is unwound through the unwinding roller, and the glue blocking film is wound through the winding roller. When the adhesive is coated, the adhesive at the windowing part is directly coated on the adhesive blocking film, and due to the shielding of the adhesive blocking film, the adhesive cannot be attached to a coating rubber roller and other guide rollers of the compound machine and cannot be transferred to the non-coated surface of the first windowing composite film, so that the product attractiveness, durability and safety of the windowing composite film are improved; and the service life of the solvent-free compound machine is also prolonged. The utility model belongs to the technical field of composite membrane manufacturing.

Description

Technical Field

[0001] The utility model relates to a device for preventing adhesive from adhering, in particular to a device for preventing adhesive from adhering to a composite machine for a window composite film, and belongs to the technical field of composite film manufacturing. Background Art

[0002] Conventional solvent-free laminating machines have the following problems in the process of producing window composite films:

[0003] When applying adhesive, the adhesive directly passes through the window opening of the composite film and then adheres to the coating roller. The adhesive continues to accumulate on the coating roller and further transfers to the non-coated surface of the composite film. At the same time, the adhesive transferred to the non-coated surface of the composite film will then be transferred to other guide rollers of the solvent-free laminating machine.

[0004] On the one hand, this situation will affect the aesthetics, durability and safety of the window composite film products. For example, the adhesive on the surface of the window paper-plastic rice packaging bag will undergo an oxidation-reduction reaction if exposed to air and sunlight for a long time, causing the outer surface of the bag to discolor and reduce its strength, thereby affecting the shelf life of the product and the safety of consumers. On the other hand, if the adhesive adheres to the guide roller of the solvent-free laminating machine and is not cleaned for a long time, it will corrode the guide roller and shorten its service life.

[0005] In summary, how to propose a device to prevent adhesive from adhering to the laminating machine in view of the above technical problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0034] The anti-adhesion unwinding unit 200 includes a first supporting top plate 250 and two first supporting side plates 210 .

[0035] One side of the first support top plate 250 is fixedly connected to the top beam, and the other side of the first support top plate 250 is installed with a first slide rail 260, which is arranged at 90° to the top beam.

[0036] A reel 240 is installed on one side of each first supporting side plate 210, and the reel 240 is used to unwind the adhesive blocking film 241. The adhesive coating unit 120 is used to coat the adhesive on one side of the first window composite film 111, and the adhesive blocking film 241 is arranged on the other side of the first window composite film 111. In this arrangement, when coating the adhesive, the adhesive at the window opening is directly coated on the adhesive blocking film 241, so as to prevent the adhesive from adhering to the components of the composite machine.

The first support shaft 230 is rotatably connected to the first support side plate 210 via a first bearing seat 220 , and the unwinding roller 240 is mounted on the first support shaft 230 .

[0041] Furthermore, the unwinding drum 240 is circumferentially fixed on the first support shaft 230 by means of set screws.

[0050] How it works

[0051] Combination Figures 1 to 6The working principle of the present invention is described by taking the production of a certain type of window structure composite film as an example:

[0052] The window structure composite film is a 4-layer film structure, and the window is opened on the first window composite film 111. During production, the first unwinding unit 110 unwinds the first window composite film 111, and the unwinding roller 240 on the anti-adhesion unwinding unit 200 unwinds the adhesive film 241.

[0053] like Figure 4 and Figure 5 As shown, the first window-opening composite film 111 and the adhesive blocking film 241 are conveyed to the adhesive coating unit 120 together. The adhesive coating unit 120 coats adhesive on one side of the first window-opening composite film 111. The adhesive blocking film 241 is arranged on the other side of the first window-opening composite film 111. When coating the adhesive, the adhesive at the window opening is directly coated on the adhesive blocking film 241 to prevent the adhesive from adhering to the coating roller.

[0054] After the first window composite film 111 and the adhesive blocking film 241 pass through the adhesive coating unit 120, when passing through the anti-adhesion winding unit 300, the winding roller 340 winds up the adhesive blocking film 241. In the above process, due to the shielding of the adhesive blocking film 241, the adhesive will not adhere to the coating rubber roller and other guide rollers of the laminating machine, and will not be transferred to the non-adhesive coating surface of the first window composite film 111.

[0055] At the same time, the first window composite film 111 continues to be transported forward. Figure 6 As shown, when passing through the compounding unit 160, the compounding unit 160 compounds the first window composite film 111 and the second composite film 171 coated with adhesive, and the composite film winding unit 180 is used to wind the composited first window composite film 111 and the second composite film 171, thereby completing the production of the window structure composite film.

[0056] The present invention has been disclosed as above in the form of a preferred embodiment, but it is not intended to limit the present invention. Any simple modification, equivalent changes and modifications made to the above implementation cases by any professional and technical personnel who do not deviate from the content of the technical solution of the present invention and based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
