Description

Technical Field

[0001] The utility model relates to the technical field of release film production, in particular to a release film coating device with good uniformity. Background Technique

[0002] A release film is a film with a separating surface, which has no stickiness or only slight stickiness after contacting a specific material under limited conditions. Release film coating is a process of preparing a glue film with a specific thickness on the surface of the release film.

[0003] The working mode of the existing release film coating device is that the coating roller dips the glue liquid from the glue storage tank and smears it on the surface of the release film. However, during the use process, the liquid level in the glue storage tank drops, and the amount of glue liquid dipped by the coating roller decreases, resulting in uneven coating of the release film. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that in the existing release film coating device during the use process, the liquid level in the glue storage tank drops, and the amount of glue liquid dipped by the coating roller decreases, resulting in uneven coating of the release film, and to propose a release film coating device with good uniformity.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A release film coating device with good uniformity includes a bottom plate and a release film. A plurality of electric push rods are fixedly connected to the top of the bottom plate, and the tops of the plurality of electric push rods are fixedly connected together with a glue storage tank. A mounting frame is fixedly connected to the top of the bottom plate. Two mounting rods are fixedly connected to the inner wall of the top of the mounting frame. A coating roller is rotatably connected to the bottom end between the two mounting rods. The release film contacts the coating roller. A tension sensor is fixedly connected to one side of one of the mounting rods. A connecting rope is fixed to the bottom end of the tension sensor. A floating ball is fixed to the bottom end of the connecting rope. The floating ball is arranged in the glue storage tank. A processor is fixedly connected to the top of the mounting frame.

[0007] Further, two first support frames are fixedly connected to the top of the bottom plate. A discharge roller is clamped between the two first support frames. The release film is wound around the discharge roller.

[0008] Further, two second support frames are fixedly connected to the top of the bottom plate. A motor is fixedly connected to one side of one of the second support frames. The output end of the motor is clamped with a winding roller. The release film is wound around the winding roller. The winding roller is rotatably connected between the two second support frames.

[0009] Further, limiting plates are sleeved on both ends of the discharge roller and the winding roller.

[0010] Further, a plurality of mounting holes are provided on the top of the bottom plate.

[0011] Furthermore, a heating wire is fixedly connected to the inner wall of the bottom of the glue storage tank.

[0012] Furthermore, a limiting frame is fixedly connected between the inner walls on both sides of the glue storage tank, and the floating ball is located inside the limiting frame.

[0013] Furthermore, the processor is electrically connected to the tension sensor and the motor.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. As the floating ball moves downward with the decrease of the liquid level of the glue in the glue storage tank, the connecting rope is pulled downward, and then a tension is applied to the tension sensor. After the tension sensor detects the tension, it transmits the information to the processor for processing. Then, the processor controls the electric push rod to work. Under the stretching of the electric push rod, the glue storage tank is driven to move upward, so that the coating roller can be better immersed in the glue, so as to evenly coat the release film with glue.

[0016] 2. By using the limiting plate to limit the two ends of the release film on the discharging roller and the winding roller, the two ends of the release film are made neater, and thus the winding quality of the release film is improved.

[0017] 3. By using the heating wire to heat the glue in the glue storage tank, the solidification of the glue is prevented, so as to better apply the glue. Description of the Drawings

A processor 20 is fixedly mounted on the top of the installation frame 4 through bolts. As the glue liquid in the glue storage tank 3 decreases, the floating ball 9 moves downward as the liquid level of the glue liquid in the glue storage tank 3 drops, thereby pulling the connecting rope 8 downward. When the tension sensor 7 detects the tension, it transmits the information to the processor 20 for processing. Then, the processor 20 controls the electric push rod 2 to work. Under the stretching of the electric push rod 2, the glue storage tank 3 is driven to move upward, so that the coating roller 6 can be better immersed in the glue liquid.

[0024] Two first support frames 10 are fixedly mounted on the top of the bottom plate 1 through bolts. A discharge roller 11 is clamped between the two first support frames 10. The design of clamping the discharge roller 11 to the first support frames 10 facilitates the installation of the discharge roller 11. The release film 15 is wound around the discharge roller 11. Two second support frames 12 are fixedly mounted on the top of the bottom plate 1 through bolts. A motor 19 is fixedly mounted on one side of one of the second support frames 12 through bolts. A winding roller 13 is clamped to the output end of the motor 19. The release film 15 is wound around the winding roller 13. Under the drive of the motor 19, the winding roller 13 rotates, thereby winding the release film 15. The winding roller 13 is rotatably connected between the two second support frames 12. Limiting plates 14 are sleeved on both ends of the discharge roller 11 and the winding roller 13. The two ends of the release film 15 on the discharge roller 11 and the winding roller 13 are limited by the limiting plates 14, so that the two ends of the release film 15 are neater. A plurality of mounting holes 16 are provided on the top of the bottom plate 1. A heating wire 17 is fixedly mounted on the inner wall of the bottom of the glue storage tank 3 through bolts.

The floating ball 9 is located in the limiting frame 18. The processor 20 is electrically connected to the tension sensor 7 and the motor 19. The model of the tension sensor 7 is BSS-1t, and the model of the processor 20 is ARM9TDMI.

[0025] Working principle: When in use, first, the discharge roller 11 wrapped with the release film 15 is clamped between two first support frames 10. Then, the free end of the release film 15 is wound around the take-up roller 13 after passing over the glue applicator roller 6. Next, driven by the motor 19, the take-up roller 13 rotates to wind up the release film 15. During the winding process, the release film 15 rubs against the glue applicator roller 6 for glue application. As the glue liquid in the glue storage tank 3 decreases, the floating ball 9 moves downward as the liquid level in the glue storage tank 3 drops, thus pulling down the connecting rope 8. When the tension sensor 7 detects the tension, it transmits the information to the processor 20 for processing. Then, the processor 20 controls the electric push rod 2 to work. Under the stretching of the electric push rod 2, the glue storage tank 3 is driven to move upward, so that the glue applicator roller 6 can be better immersed in the glue liquid.
