Description

Technical Field

[0001] This application relates to the field of membrane processing, and more specifically, to a pressing apparatus for processing release films. Background Technology

[0002] Release film, as a thin film material with special properties, is widely used in the electronics industry to protect the surface of electronic components from scratches, contamination, and other damage during processing, transportation, and storage. In the packaging field, it serves as a separating layer for packaging materials, ensuring the quality and hygiene of the contents. In the printing industry, release film is used to achieve high-quality printing effects and improve the appearance of products, and has a wide range of applications.

[0003] The production and processing of release film requires a pressing process. However, the release film pressing devices currently on the market usually adopt a direct pressing method. In actual application, it has been found that release film is prone to defects such as bubbles and wrinkles during the pressing process, which affects the pressing quality and reduces the quality of release film. Therefore, this application proposes a pressing device for release film processing. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] The purpose of this application is to address the shortcomings of the prior art by providing a pressing device for release film processing, thereby solving the problem that defects such as bubbles and wrinkles easily occur during the pressing process of release film in the prior art, which affect the pressing quality.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A pressing device for processing release film includes a processing table. A lower roller assembly and a lower pressure plate are arranged on the top of the processing table. An assembly shell is arranged above the lower roller assembly and the lower pressure plate. An upper heating pressure plate and an upper roller assembly are assembled inside the assembly shell. The upper roller assembly is aligned with the lower roller assembly. An elastic pressing member for applying downward elastic pressure to the upper roller assembly is provided on the assembly shell. A scraper is arranged between the upper heating pressure plate and the upper roller assembly. The scraper and the upper heating pressure plate are aligned with the lower pressure plate. A frame spans the assembly shell and is fixed on the processing table. A hydraulic arm for pushing the assembly shell downward as a whole is installed on the frame.

[0008] Furthermore, the frame includes four vertical arms fixed to the upper surface of the processing table, the four vertical arms are distributed on both sides of the assembly shell, and a top plate is horizontally fixed to the top of the four vertical arms. The hydraulic arm is vertically installed on the top plate, and the telescopic end of the hydraulic arm is connected downward to the assembly shell.

[0009] Furthermore, a first guide rod is vertically and movably inserted through the top plate, the first guide rod is fixedly connected to the assembly shell, and a wiring conduit is inserted through the top wall of the assembly shell.

[0010] Furthermore, the scraper has an inverted conical cross-section, the bottom end of the scraper has a rounded chamfer, and the scraper is inclined toward the side of the lower roller group and the upper roller group. The assembly shell is provided with an adjusting member for adjusting the height of the scraper.

[0011] Furthermore, the elastic pressing component includes a shell arm, vertical rods, and springs. The shell arm is fixed to the top wall of the assembly shell, the vertical rods pass through the bottom end of the shell arm, and multiple vertical rods are arranged side by side. The bottom ends of the multiple vertical rods pass through the top wall of the assembly shell. The upper roller assembly is assembled at the bottom end of the vertical rods, and the top ends of the multiple vertical rods are connected to a baffle. The baffle is movably embedded in the shell arm, and the springs are vertically arranged between the baffle and the inner top wall of the shell arm, and multiple springs are arranged side by side.

[0012] Furthermore, both the lower roller group and the upper roller group consist of a roller frame and pressure rollers rotatably mounted on the roller frame, with two pressure rollers arranged side by side.

[0013] Furthermore, the adjusting component includes a connecting plate fixed to the top of the scraper and a threaded rod that is vertically threaded through the top wall of the assembly housing. The bottom end of the threaded rod is rotatably connected to the connecting plate. A second guide rod is also vertically fixed on the connecting plate and moves through the top wall of the assembly housing.

[0014] The beneficial effects of this application are as follows:

[0015] The release film is pre-pressed by the upper and lower roller groups under the action of the elastic pressing element. At the same time, the inclined scraper removes air bubbles from the film bonding surface, effectively avoiding the problem of loose pressing caused by air bubbles during the subsequent heating and pressing process, thus improving the pressing quality of the release film. In addition, the upper heating plate and the lower pressing plate together heat the release film, which allows the layers of the release film to fuse better under heating, enhancing the adhesion between the layers and ensuring the overall performance of the release film.

[0016] The adjustable components allow the height of the scraper to be adjusted according to release films of different thicknesses and properties, improving the applicability and flexibility of the device and enabling it to meet the processing needs of various release films.

A lower roller assembly 8 and a lower pressure plate 3 are arranged on the top of the processing table 1. An assembly shell 2 is arranged above the lower roller assembly 8 and the lower pressure plate 3. A frame spans the assembly shell 2, and the frame consists of four vertical arms 4 and a top plate 5. The four vertical arms 4 are vertically fixed to the upper surface of the processing table 1, and are distributed on both sides of the assembly shell 2. The top ends of the four vertical arms 4 are horizontally fixed to the top plate 5. A hydraulic arm 6 is vertically mounted on the top plate 5, and the telescopic end of the hydraulic arm 6 is connected downwards to the assembly shell 2. A first guide rod 7 is vertically movably inserted through the top plate 5, and the bottom end of the first guide rod 7 is fixedly connected to the assembly shell 2 to ensure the stability of the assembly shell 2 during vertical movement.

[0031] Furthermore, in this embodiment, the assembly shell 2 is equipped with an upper heating pressure plate 9 and an upper roller group 10. The upper roller group 10 is aligned with the lower roller group 8. A wiring conduit 14 is provided on the top wall of the assembly shell 2 for connecting the upper heating pressure plate 9 to an external power source for heating. Both the lower roller group 8 and the upper roller group 10 consist of a roller frame 18 and pressure rollers 19 rotatably mounted on the roller frame 18. Two pressure rollers 19 are arranged side by side. An elastic downward pressing component 11 is provided on the assembly shell 2 to apply downward elastic pressure to the upper roller group 10. The elastic downward pressing component 11 includes a shell arm 20, a vertical rod 21, a baffle 22, and a spring 23. The shell arm 20 is fixed to the top wall of the assembly shell 2, and the vertical rods 21 pass through the bottom end of the shell arm 20, with multiple vertical rods arranged side by side. The bottom ends of the multiple vertical rods 21 penetrate the top wall of the assembly shell 2, and the upper roller group 10 is assembled at the bottom end of the vertical rods 21. Multiple vertical rods 21 are connected to a baffle 22 at their top ends. The baffle 22 is movably embedded in the shell arm 20. Springs 23 are vertically arranged between the baffle 22 and the inner top wall of the shell arm 20, and multiple springs are arranged side by side.

[0032] Furthermore, in this embodiment, a scraper 12 is provided between the upper heating platen 9 and the upper roller group 10, and the scraper 12 and the upper heating platen 9 are aligned with the lower pressure plate 3. The scraper 12 has an inverted conical cross-section, and the bottom end of the scraper 12 has a rounded chamfer.

[0033] Working principle: In use, the release film pressing device first inserts the release film between the lower roller group 8 and the upper roller group 10, then sequentially passes between the upper heating platen 9 and the scraper 12 and the lower pressure plate 3. The hydraulic arm 6 is activated, pushing the assembly shell 2 downwards. During the downward pressing of the assembly shell 2, the elastic pressing component 11 applies downward elastic pressure to the upper roller group 10, causing the release film to be initially compressed between the upper roller group 10 and the lower roller group 8, achieving pre-pressing.

[0034] Next, the inclined scraper 12 scrapes away air bubbles on the release film bonding surface as it passes by, ensuring the flatness of the release film bonding surface. Subsequently, the upper heating plate 9 heats the release film, and together with the lower pressure plate 3, further presses the release film to ensure the pressing effect of the release film and make the layers of the release film tightly bonded.
