Description

Technical Field

[0001] The utility model belongs to the technical field of glue coating equipment, and in particular relates to a film plate back glue coating device. Background Art

[0002] A keyboard anti-slip mat is an auxiliary accessory used to increase the friction between the keyboard and the desktop. Common materials for keyboard anti-slip mats include rubber and silicone. To facilitate production, the existing technology usually places multiple keyboard anti-slip mats on a film board, which is then coated with adhesive and covered with a protective film.

[0003] A Chinese patent with announcement number CN220697235U discloses a gray board paper glue smearing mechanism, which includes a workbench, a gantry fixed on the end face of the workbench, a hydraulic cylinder fixedly installed at the center of the lower end face of the crossbeam on the top of the gantry, and a cross frame fixedly connected to the end of the hydraulic cylinder output shaft. A drive roller is provided under the cross frame, and a fixed sleeve outside the drive roller is provided with a perforated sleeve layer. A glue groove is provided inside the cross frame, and a scraper is rotatably provided at the front end of the liquid outlet groove provided at the bottom of the cross frame. The above scheme allows the glue in the glue groove to flow evenly onto the rotating perforated sleeve layer, so that the scraper scrapes off excess glue on the surface of the perforated sleeve layer, so that the thickness of the glue layer smeared on the gray board paper is uniform.

[0004] The above scheme can be used for coating the back glue of the film plate after adjustment. However, when the above scheme is used, the glue scraped off by the scraper is easy to drip from both ends of the scraper, and this part of the glue cannot be collected, which is easy to pollute the working environment and waste glue. Utility Model Content

[0005] The utility model aims to provide a film plate adhesive coating device to solve the problem that the scraped glue cannot be collected in the above solution.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] The top of the movable frame is open and the top of the movable frame is fixedly provided with an electric push rod. The top of the movable frame is provided with a transmission mechanism below the mounting frame. The movable frame is in an inverted U shape, and the top of the movable frame is fixedly connected to the output end of the electric push rod. A rotating shaft is inserted in the movable frame for horizontal rotation, and a glue coating roller is fixedly sleeved on the outer wall of the rotating shaft in the movable frame. A glue storage box is provided above the glue coating roller in the movable frame, and an opening is provided at the bottom of the glue storage box. A motor connected to the rotating shaft for transmission is fixedly provided on the top of the movable frame. The glue collecting mechanism includes a glue collecting box and a scraper. The top of the glue collecting box is open, and the glue collecting box is fixedly provided at the bottom of the movable frame. The scraper is arranged in the movable frame along the horizontal direction, and the top of the scraper can abut against the glue coating roller, and the bottom of the scraper is located above the glue collecting box.

[0008] The principle and effect of this technical solution:

[0009] Multiple film plates are placed one by one on the conveying mechanism, which carries the film plates under the glue coating roller and passes through the glue coating roller. The glue in the glue storage box flows through the opening to the surface of the glue coating roller. The top of the scraper scrapes the glue on the surface of the glue coating roller evenly. The excess glue flows downward along the upper surface of the scraper and drips into the glue collection box along the bottom of the scraper, driving the electric push rod to move the movable frame downward and the motor to drive the glue coating roller to rotate. The glue coating roller evenly coats the glue on the film plate.

[0010] Through the above arrangement, a glue collection box with an open top is fixedly set at the bottom of the movable frame, and the bottom of the scraper is located above the glue collection box, so that the device can collect the glue scraped off by the scraper, avoiding pollution to the working environment and saving glue at the same time.

[0011] In this utility model, a connecting shaft that rotatably penetrates the movable frame is fixedly mounted at each end of the bottom of the scraper. A sleeve is fixedly mounted on the outer wall of the movable frame around the outer periphery of the connecting shaft. A coil spring is mounted within the sleeve, and the ends of the coil spring are connected to the inner wall of the sleeve and the outer wall of the connecting shaft, respectively. This arrangement allows the top of the scraper to be in close contact with the glue roller, preventing the gap between the glue roller and the scraper from widening due to wear of the glue roller after long-term use.

[0012] In the present invention, the bottom of the glue collecting box is tilted so that the left side is lower and the right side is higher. A glue outlet pipe is provided at the bottom of the left side of the inner cavity of the glue collecting box. This arrangement allows the glue in the glue collecting box to be promptly transferred out to prevent the glue in the glue collecting box from overflowing.

[0013] In the utility model, a cross bar is fixedly provided in the movable frame on the side of the rotating shaft away from the scraper, and a baffle is fixedly sleeved outside the cross bar. One end of the baffle is rotatably sleeved on the rotating shaft, and two glue coating rollers are symmetrically provided on both sides of the baffle.

[0014] The principle and effect of this technical solution:

[0015] When the glue roller applies glue to the surface of the film sheet, there is adhesion between the glue roller and the film sheet. Because the film sheet is usually made of rubber or silicone and has a soft texture, when the adhesion is greater than the gravity of the film sheet, the film sheet is easy to adhere to the surface of the glue roller. When the film sheet adheres to the glue roller and moves upward, the baffle intercepts it and separates the film sheet from the glue roller.

[0016] The above arrangement can prevent the flexible film sheet from adhering to the surface of the glue coating roller, thereby improving the adhesive coating effect of the device.

[0017] In the present invention, the rotating shaft is connected to the motor via a transmission belt. Through the above arrangement, it is convenient for the staff to rotate the glue coating roller, thereby improving the practicality of the device.

[0018] In the present invention, a vertical through hole is provided on the top of the mounting frame, and a guide rod that slides through the through hole is fixedly provided on the top of the movable frame. Through the above arrangement, the movable frame can be ensured to move vertically.

[0019] In the present invention, a glue injection port connected to the glue storage box is provided on the top of the movable frame. Through the above arrangement, it is convenient to add glue to the glue storage box, thereby improving the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom of the scraper 42 is located above the glue collecting box 41, and the lower edge of the glue collecting box 41 is higher than the lower edge of the glue coating roller 31.

[0028] In this embodiment, the two ends of the bottom of the scraper 42 are respectively fixed with a connecting shaft 421 that is rotatably installed in the movable frame 20. The outer wall of the movable frame 20 is fixed with a sleeve 23 on the outer periphery of the connecting shaft 421. A coil spring 50 is provided in the sleeve 23, and the two ends of the coil spring 50 are respectively connected to the inner wall of the sleeve 23 and the outer wall of the connecting shaft 421.
