Description

Technical Field

[0001] This utility model relates to the field of release film processing technology, specifically to a release film coating device for release film processing. Background Technology

[0002] Release film is a functional film with low or non-stick properties on its surface. Its core characteristic is "easy peeling," allowing it to be temporarily bonded to various adhesive materials (such as tapes, adhesives, and composite materials). It can be easily separated when needed, leaving no adhesive residue and without damaging the bonding surface. It is widely used in electronics, packaging, die-cutting, new energy, and other fields, and is a key auxiliary material for ensuring efficient production processes and product quality.

[0003] In the process of releasing film processing, a release film coating device is required. Chinese utility model patent CN213078969U discloses a coating device for releasing film production, belonging to the field of release film technology. It includes a workbench with two fixed plates above it. A connecting plate is fixedly connected between the two fixed plates. Four fixed blocks and a coating box are located above the connecting plate, with the coating box positioned in the middle of the four fixed blocks. A connecting pipe is located below the coating box, penetrating the connecting plate. A coating head is located below the connecting pipe. An electric push rod is bolted to one side of one of the fixed plates, and a locking block is welded to one side of the electric push rod. The locking block engages with the coating head. This utility model, by setting up an electric push rod, a screw, and a locking block, allows the screw to easily fix the coating head within the locking block. The electric push rod drives the coating head to extend and retract, increasing the coating area and avoiding affecting work efficiency.

[0004] However, in the process of using this utility model, the glue applicator can only apply glue to a specific area on the surface of the discrete film, and cannot achieve a completely uniform coating. This makes the entire glue application process extremely cumbersome and cannot meet the processing requirements. Therefore, a release film glue applicator for release film processing is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a release film coating device for release film processing, which has the advantage of uniform coating. It solves the problem that existing coating equipment can only coat specific areas on the surface of discrete films with the coating head, and cannot achieve completely uniform coating, resulting in an extremely cumbersome coating process that cannot meet processing requirements.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a release film coating device for release film processing, comprising a worktable and a first support frame fixedly connected to the top of the worktable, a second support frame fixedly connected to the side of the top of the worktable away from the first support frame, and an coating mechanism capable of uniformly coating the release film is provided inside the first support frame.

[0007] The glue application mechanism includes two glue application rollers rotatably connected inside the first support frame. The front of the first support frame is rotatably connected to two transmission wheels that can simultaneously drive the two glue application rollers to rotate. A transmission belt is connected between the two transmission wheels. A drive motor that can drive the glue application rollers is fixedly connected to the back of the first support frame. A storage box is slidably connected to the upper surface of the worktable.

[0008] Furthermore, both of the adhesive rollers extend into the interior of the storage bin, which contains adhesive material.

[0009] Furthermore, the number of the adhesive rollers is four, and a mounting frame is slidably connected inside the first support frame, wherein two of the adhesive rollers are rotatably connected inside the mounting frame.

[0010] Furthermore, a telescopic cylinder extending into the top of the first support frame is fixedly connected to the top of the first support frame, the output end of the telescopic cylinder is fixedly connected to the mounting frame, and a positioning guide rod extending to the top of the first support frame is fixedly connected to the top of the mounting frame.

[0011] Furthermore, a collection box is slidably connected to the upper surface of the workbench, and the collection box is also slidably connected to the inside of the second support frame.

[0012] Furthermore, the second support frame has a connecting plate inside, and a threaded rod extending to the top of the second support frame is rotatably connected to the top of the connecting plate. The threaded rod is connected to the second support frame by a threaded connection, and a rotating handle is fixedly connected to the top of the threaded rod.

[0013] Furthermore, a guide plate is fixedly connected to the side of the connecting plate near the first support frame, and a uniform brush is fixedly connected to the bottom of the connecting plate.

[0014] Furthermore, the front and back of the connecting plate are fixedly connected with positioning blocks extending into the interior of the second support frame, and the inner wall of the second support frame is provided with positioning grooves that are adapted to the positioning blocks.

[0015] Compared with the prior art, the present invention provides a release film coating device for release film processing, which has the following beneficial effects:

[0016] 1. This release film coating device for release film processing uses two coating rollers, a drive wheel, and a drive belt. A single drive motor can synchronously drive the two coating rollers to rotate in opposite directions. This design ensures the synchronicity and uniformity of coating both sides or one side of the release film, effectively avoiding problems such as uneven coating and streaks that may occur with traditional single-roller coating, and significantly improving the coating quality. The storage box is slidably connected to the worktable, which is convenient for moving and disassembling, facilitating the replenishment and replacement of adhesive and the cleaning and maintenance of the box, ensuring the purity of the adhesive and the stability of the coating effect.

[0017] 2. This release film coating device for release film processing adjusts its height by rotating a threaded rod, ensuring good contact with release films of different thicknesses. The uniform brush evenly spreads any areas of excessively thick adhesive after coating, while the guide plate guides and collects excess adhesive, resulting in a smoother and more uniform adhesive layer on the release film surface. This further guarantees the quality of the final product and solves the problem of existing coating equipment that relies on the coating head to only coat specific areas of the discrete film surface, failing to achieve completely uniform coating and making the entire coating process extremely cumbersome and unable to meet processing requirements.

A storage box 7 is slidably connected to the upper surface of the workbench 1.

[0024] Specifically, both glue-applying rollers 4 extend into the interior of the storage bin 7, which contains glue material. There are four glue-applying rollers 4. The first support frame 2 is slidably connected to the mounting frame 9, and both glue-applying rollers 4 are rotatably connected to the interior of the mounting frame 9.

[0025] It should be noted that a telescopic cylinder 10 extending into the top of the first support frame 2 is fixedly connected to the top of the first support frame 2. The output end of the telescopic cylinder 10 is fixedly connected to the mounting frame 9. A positioning guide rod extending to the top of the first support frame 2 is fixedly connected to the top of the mounting frame 9. By setting the mounting frame 9 driven by the telescopic cylinder 10, the positions of the two coating rollers 4 can be precisely adjusted.
