Description

A reciprocating PVC film glue spraying machine with high uniformity and its application method

technical field

The invention relates to the field of blister film processing equipment, in particular to a reciprocating PVC film glue spraying machine with high uniformity and a use method thereof.

Background technique

With the development of the times, PVC is gradually winning people's favor with its good performance, simple process and many other advantages, and has been accepted and recognized by more and more people. PVC can be seen everywhere in people's daily life. The essence of PVC is a vacuum blister film, which is used for the surface packaging of various panels, so it is also called decorative film and adhesive film, and is used in many industries such as building materials, packaging, and medicine.

The process of pasting the PVC film on the workpiece is called film pressing. Before the film pressing, an appropriate amount of glue should be applied on the PVC side to ensure the firmness of the film pressing. At present, the glue coating method is mainly divided into roller coating method and spray coating method. When using the roller method, it is necessary to use a coating roller to directly coat the glue on the surface of the PVC film. The coating thickness is difficult to control, and the coating will be uneven. And the glue is easy to accumulate on the surface of the coating roller, resulting in uneven surface of the rubber roller, and even leaving marks on the PVC film, which affects its aesthetics; when using the spraying method, since the position of the spray gun is mostly fixed, the position of the glue spraying will appear. The problem of poor uniformity of glue spraying caused by a single one. In addition, even when the spray gun is not in use, the glue accumulated at the nozzle of the spray gun often drips outside the meeting, thereby polluting the glue application device and PVC film.

Contents of the invention

In order to make up for the deficiencies of the prior art, the invention provides a reciprocating PVC film glue spraying machine with high uniformity and a use method thereof.

The technical problems to be solved by the present invention are achieved by adopting the following technical solutions: a reciprocating PVC film glue spraying machine with high uniformity, including a base plate, a workbench, a mounting plate, an auxiliary frame and a glue spraying mechanism, and the upper end of the base plate is installed There is a working table, the rear end of the bottom plate is installed with a mounting plate, and the front end of the mounting plate is sequentially installed with an auxiliary frame and a glue spraying mechanism from top to bottom; among them:

The auxiliary frame includes a shielding frame, an installation branch chain, a dust cleaning branch chain and a scraper plate. The shielding frame is installed at the front end of the mounting plate. The shielding frame is an Ω-shaped structure. Left and right symmetrical arrangement, the lower end of each set of positioning holes is equipped with installation branch chain, the lower end of the installation branch chain at the right end of the shielding frame is installed with a dust removal branch chain, and the lower end of the installation branch chain at the left end of the shielding frame is installed with a scraper plate, the scraper plate is inverted T-shaped structure; dust-cleaning branch chain can clean dust and other sundries on the PVC film, and the shielding frame can prevent dust and other sundries in the external environment from adhering to the PVC film to ensure the effect of glue spraying. After gluing, the glue on the surface of the PVC film is spread evenly, and the excess glue is scraped off.

The glue spraying mechanism includes a reciprocating motor, a limiting cylinder, a control frame, a spray gun, a driving motor, a driving rod and a driving block. Connection, the side wall of the limit cylinder is uniformly provided with limit slots along its circumferential direction.
