Problems solved by technology

However, in the film manufacturing process, sometimes the film is disconnected, so that the film cannot meet the customer's requirements for the length of the film. The general method is to use adhesive tape to connect two sections of film together. The problems of this method are: The cohesive force of the tape makes wrinkles appear on the connected film, and because the materials of the tape and the film are different, the film connected by the tape is not continuous, which affects the use effect of the film

Embodiment

[0022] A method of joining thin films using a device such as figure 1 , figure 2 As shown, the method includes the following steps:

[0023] (1) The ends of the two sections of film 1 to be connected are cut neatly;

[0024] (2) Connect the box body 3 with the fine air port 31 on the flat surface to the vacuum device 4;

[0025] (3) Put the ends of the two neatly cut films 1 to be connected on the surface of the casing 3 provided with fine air ports 31;

[0026] (4) Open the vacuum device 4, so that the two sections of films 1 to be connected are flatly attached to the surface of the box body 3, and the ends of the films 1 to be connected are adjusted to be aligned;

[0027] (5) Coat the junction of the two sections of films 1 to be connected with UV-curable glue, and then place a neatly cut connection film 2 on the UV-curable glue;

[0028] (6) The connecting film 2 is irradiated with the ultraviolet light source 5 , and the ultraviolet light curing glue is cured to conn...

Abstract

The invention relates to a connection method for films. The method comprises the following steps: neatly cutting end parts of two to-be-connected films; connecting a case which is provided with fine and close gas ports in its smooth surface with a vacuum-pumping device; placing the end parts of the two neatly cut to-be-connected films on the surface of the case provided with the fine and close gas ports; starting the vacuum-pumping device so as to allow the two to-be-connected films to be flatly adhered onto the surface of the case and aligning the end parts of the two to-be-connected films; coating the joint of the two to-be-connected films with an ultraviolet light curing adhesive and placing a neatly cut connection film on the ultraviolet light curing adhesive; and irradiating the connection film with an ultraviolet light source and allowing the ultraviolet light curing adhesive to be cured so as to enable the two to-be-connected films to be connected together. Compared with the prior art, the method provided by the invention has the following advantages: the joint of the films is flat and smooth and leaves no connection trace, the connection film at the joint has same performance as films at other places; and the method has the advantages of easiness, easy availability of equipment, conservation of energy, environmental protection, etc.

Description

technical field [0001] The invention belongs to the field of film manufacture, and in particular relates to a method for connecting films. Background technique [0002] Most of the films used as various tapes or packaging materials are continuously manufactured in the shape of long tapes in the manufacturing process, and customers need complete, continuous films with sufficient length. However, in the film manufacturing process, sometimes the film is disconnected, so that the film cannot meet the customer's requirements for the length of the film. The general method is to use adhesive tape to connect two sections of film together. The problems of this method are: The cohesive force of the adhesive tape causes wrinkles to appear on the connected films, and because the materials of the adhesive tape and the film are different, the films connected by the adhesive tape do not have continuity, which affects the use effect of the film. Contents of the invention [0003] The obj...
