Description

Technical Field

[0001] The utility model relates to the technical field of packaging film processing, in particular to a glue uniform coating device for packaging film. Background Art

[0002] Packaging films are mostly formed by compounding multiple layers of film materials. During the compounding process of packaging films, adjacent film materials need to be bonded with glue. During bonding, a glue coating mechanism is generally used to coat the surface of the film with glue. The commonly used glue coating mechanism is inconvenient to operate and is prone to uneven glue coating, which affects the performance of the packaging film and is prone to glue leakage and waste.

[0003] For example, our company's previous application for a patent document with announcement number CN216727933U discloses a packaging film composite glue coating mechanism, including a supporting assembly component, a glue supporting component, a transfer guide component, a glue limiting component, a glue recovery component and a glue replenishing component. The glue coating mechanism is provided with a fixed roller and a movable roller, and a wedge-shaped supporting space is formed between the fixed roller and the movable roller. When the movable roller rotates, it carries the glue to be coated on the surface of the film material. A limiting fence that can move with the limiting seat body is also provided to limit the glue in the wedge-shaped supporting space. The glue coating range can be adjusted according to the size of the film material. A recovery trough is also provided to recover the glue leaked from the limiting fence, the fixed roller and the movable roller. A liquid replenishment conduit installed on the liquid replenishment bracket is also provided, which can move back and forth along the liquid replenishment guide rod with the liquid replenishment bracket, so that the glue in the glue supply device enters the wedge-shaped supporting space through the liquid replenishment conduit and is evenly distributed in the wedge-shaped supporting space, thereby improving the glue coating quality.

[0004] In the above scheme, the packaging film composite glue coating mechanism carries the glue to the surface of the film material when the movable roller rotates. However, when the glue output from the liquid replenishing duct is unstable, especially when the output is large, it will cause uneven glue coating, affecting the quality of the packaging film and causing glue waste. In addition, the distance between the film material and the movable roller should not be too close to avoid the glue from contaminating the film material under the action of centrifugal force and affecting the quality of the film material. Therefore, it is necessary to provide a glue uniform coating device for packaging film to solve the shortcomings of the prior art. Utility Model Content
