Description

Technical Field

[0001] This utility model relates to the technical field of adhesive spraying devices, specifically an adhesive spraying device for sealing release film of express delivery bags. Background Technology

[0002] The express bag sealing release film adhesive spraying device is a device used to spray adhesive at the sealing point of express bags. It is mainly used to spray a layer of hot melt adhesive at the sealing point of the express bag, and then attach release paper. When the sender needs to seal the bag, he only needs to tear off the release paper, and the hot melt adhesive will seal the bag. It is easy to operate and has a good sealing effect. The device uses a hot melt adhesive machine for automatic sensing and fast glue application, which can ensure that the glue length is standard and the glue breaks cleanly each time, resulting in excellent bonding effect. The adhesive used is a hot melt self-adhesive, which requires less dosage and has a good effect.

[0003] For example, the adhesive applicator for express delivery bags disclosed in the authorization announcement number CN220009013U includes a platform, a gantry frame fixedly installed on the top of the platform, a bracket fixedly installed on the outer wall of one side of the top of the gantry frame, a roll of release film fixedly installed on the bracket, a sliding component installed on the gantry frame, and an adhesive applicator installed on the gantry frame through the sliding component, a hanger fixedly installed below the sliding component, and an electric gripper installed at the bottom of the hanger;

[0004] Although it enables the sliding components to move on the gantry via a power unit, allowing the gluing mechanism to apply glue at the sealing point of the express bag, and automatically attaches the release film to the glued position after gluing, the system has a high degree of automation, improving the efficiency of gluing express bags. It can drive the glue gun in the gluing mechanism to move up and down inside the fixed ring, thereby realizing the switching between gluing and workstation. The electric gripper pulls the release film out, and the pressure plate performs film pressing on the release film at the gluing position, improving the quality of gluing express bags. While pressing the film, the shearing blade on the pressure plate can cut the release film, making it easy to use for gluing the next express bag. The overall device has good continuity and greatly improves the efficiency of express bag processing.

[0005] However, this does not solve the problem that existing adhesive spraying devices of this type are generally not conducive to convenient reciprocating spraying, affecting the uniformity of the release film spraying, making it inconvenient to conveniently spray the release film in a quantitative manner, affecting the efficiency of the adhesive spraying device, and making it inconvenient to conveniently adjust the position of the adhesive spraying device in multiple stages for spraying, thus affecting the flexibility of the adhesive spraying device in multi-stage movement and adjustment for spraying.
