Description

Technical Field

[0001] The utility model relates to the technical field of protective film gluing devices, in particular to a gluing device for plastic protective films. Background Art

[0002] Protective films can be classified into digital product protective films, automotive protective films, household protective films, food preservation protective films, etc. according to their uses. Functionally, a protective film is a layer of film placed outside the physical object to be protected. There are already functional protective films on the market, such as AR anti-reflection films, AG matte anti-reflection films, mobile phone mirror films, privacy films, high-definition scratch-resistant films, etc.

[0003] According to Chinese Patent CN 211707140 U, a gluing device for protective film production is proposed. By driving a driving roller to rotate with a driving motor, and under the mutual cooperation of the driving roller and the guiding roller, the protective film after spraying glue is conveyed into the drying chamber, and heating operation is carried out through the heating device inside the drying chamber. And with the blowing cooperation of a blower, the hot air flow after drying passes through a plurality of air outlets opened at the bottom of the heating device to quickly dry the protective film after spraying glue, and is centrally collected by a winding roller. This device adopts a structure of spraying and drying in one, which can not only carry out spraying and drying simultaneously, saving time, but also greatly improve the overall working efficiency of protective film processing.

[0004] However, there may be some deficiencies in this patent. In this device, the surface of the protective film can be coated with glue through a glue spraying head, but there is no device for straightening the protective film in the device. It may cause the surface of the protective film to become slack due to the heavy glue coating during the process of coating the protective film, resulting in uneven glue coating on the surface of the protective film, thus affecting the gluing effect of the device on the protective film. For this reason, we propose a gluing device for plastic protective films. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a gluing device for plastic protective films, which solves the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A gluing device for plastic protective films, including a mounting plate;

[0007] Support legs fixedly installed at the bottom of the mounting plate;

[0008] A winding mechanism body fixedly installed on the top of the mounting plate;

[0010] And a processing component arranged above the mounting plate, the processing component includes a straightening mechanism fixedly mounted on the top of the mounting plate, and the straightening mechanism is connected with a glue coating mechanism.

[0011] Preferably, the straightening mechanism includes a cylinder fixedly mounted on the top of the mounting plate. The top outer wall of the output end of the cylinder is movably mounted through a hinge with a movable rod. A limiting cross column is fixedly mounted on the side wall of one end of the movable rod. The outer wall of the limiting cross column is slidably connected with a limiting frame. The bottom of the limiting frame is fixedly mounted with a support plate. The bottom of the support plate is fixedly connected with the top of the mounting plate. A U-shaped block is fixedly mounted at one end of the movable rod. A rotating rod is rotatably connected to the inner wall of the U-shaped block through a bearing. An extrusion wheel is fixedly mounted on the outer wall of the rotating rod.

When the output end of the cylinder pushes upward, it will slide through the limiting cross column inside the limiting frame, causing the movable rod to rotate. During the rotation of the movable rod, the U-shaped block will be lifted, causing the extrusion wheel inside the U-shaped block to be lifted, so that the extrusion wheel squeezes the bottom of the plastic protective film body to achieve the effect of straightening the plastic protective film body, thereby improving the glue coating effect of the device on the plastic protective film body and preventing the plastic protective film body from sagging and affecting the glue coating effect.

The operator can turn on the motor to drive the bidirectional threaded rod to rotate. During the rotation of the bidirectional threaded rod, the socket block will be driven to move, so as to drive the cleaning brush to move. During the movement of the cleaning brush, the glue on the surface of the plastic - protective film body can be evenly brushed, so that the glue can be evenly distributed on the surface of the plastic - protective film body. In addition, the operator can turn on the blower fan and the heating generator, so that the air blown out by the blower fan becomes hot air after passing through the heating generator and is discharged through the through - slots, so as to dry the glue on the surface of the plastic - protective film body through the hot air.
