Description

Technical Field

[0001] This utility model relates to the field of embossing device technology, and specifically to an embossing mechanism for release paper processing. Background Technology

[0002] Release paper, also known as release liner, anti-stick paper, or silicone paper, is a type of paper used to prevent prepreg from sticking together and to protect it from contamination. Existing release papers mainly consist of three layers: the first layer is the base paper, which provides support; the second layer is the coating, usually a polyethylene film, which enhances the paper's waterproof and oil-proof properties; and the third layer is silicone oil, which gives the release paper its anti-stick properties. Embossing creates uneven textures on the surface of the release paper. Embossing reduces the actual contact area between the release paper and the adhesive. When the adhesive is applied to the embossed release paper, the adhesive layer only fills the recessed areas of the embossing, while the raised areas form air layers. This reduces the adhesion between the adhesive and the release paper, making the release process smoother and avoiding problems such as difficulty in tearing or adhesive residue. Therefore, an embossing mechanism is needed to emboss the surface of the release paper.

[0003] The release paper embossing mechanism is a device used to press specific textures or patterns onto release paper. The embossing mechanism mainly consists of an embossing roller and a support roller. When the release paper passes between the support roller and the embossing roller, the texture on the surface of the embossing roller will press the corresponding pattern or texture onto the release paper.

[0004] While existing embossing mechanisms offer numerous advantages, they still suffer from several drawbacks. Firstly, they are not sufficiently effective at cleaning the embossing roller. During the embossing process, some fibers from the release paper detach due to the embossing process. These detached fibers become trapped inside the embossing grooves of the roller, causing them to become clogged and affecting the cleanliness of the groove boundaries. Consequently, this impacts the clarity and quality of the embossing on the release paper. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides an embossing mechanism for release paper processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is an embossing mechanism for release paper processing, including a base plate, a support frame, and a support cover. A fixing frame is screwed to one side of the upper outer wall of the base plate. The support frame is set inside the fixing frame. An embossing roller is rotatably installed inside the support frame. The embossing roller protrudes from the end of the support frame and is connected to a turbine by a pin. A support cover is set on the outside of the support frame. Rotating shafts are rotatably installed on both sides of the inner wall of the support cover. Rubber strips are sleeved on the outer walls of both sides of the rotating shafts. Equally spaced parallel brushes are glued and fixed to the outer walls of the rubber strips. The brushes are in contact with the outer wall of the embossing roller. A dust suction pipe is welded to the outer wall of the support cover. The dust suction pipe is connected to the inside of the support cover, and a flange is welded to the dust suction pipe away from the outer wall of the support cover.

[0007] By adopting the above technical solution, the base plate provides a stable embossing platform for the device, ensuring embossing accuracy. When the release paper moves between the support roller and the embossing roller, the embossing roller can perform embossing processing on one side of the release paper, ensuring the quality of the texture formation on the surface of the release paper. During the embossing process, the embossing roller drives the rotating shaft to rotate circumferentially through a turbine and worm gear, thereby driving the rubber belt to rotate on the outside of the rotating shaft. Since the brush contacts the outer wall of the embossing roller, it can simultaneously remove paper scraps, glue stains and other impurities remaining on the roller surface during the embossing process, ensuring the clarity of the embossing groove boundary on the embossing roller surface, avoiding impurities from affecting the embossing quality or causing the release paper to stick. Moreover, the cleaning is driven by the rotation of the embossing roller itself, without the need for an additional power source, saving energy. The matching vacuum cleaner is connected to the flange of the vacuum pipe, which can absorb and collect the cleaned and detached impurities, ensuring the cleanliness of the working environment and avoiding secondary pollution from impurities.

[0008] Specifically, a support frame is screwed to the outer wall of the base plate on the side away from the fixing frame. A take-up roller is installed inside the support frame. A motor is installed through one end of the outer wall of the take-up roller, and the output end of the motor is connected to the end of the take-up roller by a coupling.

[0009] By adopting the above technical solution, it is shown that the support frame can maintain the position of the take-up roller, ensuring the stability of the take-up roller in winding the release paper after embossing. The motor directly drives the take-up roller through the coupling, and with the matching controller, the winding speed and tension can be precisely controlled. The motor can drive the take-up roller to automatically wind up the release paper after embossing is completed.

[0010] Specifically, guide rods are threadedly connected to both sides of the upper outer wall of the support frame, and the guide rods are movably installed inside the fixed frame.

[0011] By adopting the above technical solution, the guide rod restricts the movement direction of the support frame, ensuring that it rises and falls smoothly in the vertical direction, avoiding deviation during adjustment, and providing precise guidance for the pressure adjustment of the embossing roller and release paper.

[0012] Specifically, the fixing frame has an internal threaded connection to an adjusting screw, and a bearing is interference-fitted to one side of the upper outer wall of the support frame. The lower end of the adjusting screw is interference-fitted to the inner ring of the bearing, and the adjusting screw is rotatably connected to the support frame through the bearing.

[0013] By adopting the above technical solution, rotating the adjusting screw can drive the support frame to move up and down, thereby adjusting the pressure of the embossing roller on the release paper and adjusting the pressing depth of the embossing on the release paper surface. It can adapt to the production requirements of different specifications. The threaded connection has a self-locking function. After adjusting to the appropriate pressure, no additional locking device is required, and the pressure can be kept stable.

[0014] Specifically, a drive motor is provided at the end of the embossing roller through the support frame. The drive motor is screwed to the outer wall of the support frame, and the output end of the drive motor is connected to the end of the embossing roller by a coupling.

[0015] By adopting the above technical solution, the drive motor can drive the embossing roller to rotate through the coupling, and with the controller, the speed and torque of the embossing roller can be precisely controlled to ensure the clarity and consistency of the embossing pattern. When the drive motor drives the embossing roller to rotate, it can drive the release paper between the support roller and the embossing roller to move, maintaining continuous embossing on the release paper.

[0016] Specifically, a support roller is rotatably mounted on one side of the inner wall of the fixed frame, and the support roller is located at the lower end of the embossing roller.

[0017] By adopting the above technical solution, the support roller can lift the release paper, keeping it flat when it enters the embossing area, thus stabilizing the embossing process of the release paper by the embossing roller.

[0018] Specifically, a worm gear is interference-fitted onto one side of the outer wall of the shaft, and two rubber belts are distributed on the upper and lower sides of the screw. The worm gear meshes with the turbine.

[0019] By adopting the above technical solution, when the embossing roller rotates, the turbine drives the worm gear to rotate, which in turn drives the rotating shaft and rubber belt to rotate, so that the brush continuously cleans the surface of the embossing roller.

[0020] Specifically, connectors are welded to both sides of the upper outer wall of the support cover, and the other end of the connector is screwed to the upper outer wall of the support frame.

[0021] By adopting the above technical solution, the connector can ensure the positional stability of the support cover outside the support frame, and ensure stability during the brush cleaning process.

[0022] The beneficial effects of this utility model are:

[0023] The embossing mechanism for release paper processing described in this utility model uses a brush to simultaneously remove residual paper scraps, glue stains, and other impurities from the roller surface during the embossing process. This ensures the clarity of the embossing groove boundaries on the roller surface, preventing impurities from affecting the embossing quality or causing the release paper to stick. Furthermore, the cleaning is driven by the rotation of the embossing roller itself, eliminating the need for an additional power source and saving energy. The accompanying vacuum cleaner is connected to the flange of the vacuum pipe, enabling the extraction and collection of cleaned and detached impurities, ensuring a clean working environment and preventing secondary pollution from impurities.

[0024] The present invention discloses an embossing mechanism for processing release paper. When the release paper moves between the support roller and the embossing roller, the embossing roller can perform embossing processing on one side of the release paper, ensuring the quality of the texture formation on the surface of the release paper.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the embossing mechanism for release paper processing according to this utility model includes a base plate 1, a support frame 2, and a support cover 3. A fixing frame 11 is screwed to one side of the upper outer wall of the base plate 1. The support frame 2 is set inside the fixing frame 11. An embossing roller 22 is rotatably installed inside the support frame 2. The embossing roller 22 protrudes from the end of the support frame 2 and is connected to a turbine 24 by a pin. The support cover 3 is set on the outside of the support frame 2. A rotating shaft 33 is rotatably installed on both sides of the inner wall of the support cover 3. A rubber strip 35 is sleeved on both sides of the outer wall of the rotating shaft 33. Equally spaced parallel brushes 36 are glued and fixed to the outer wall of the rubber strip 35. The brushes 36 are in contact with the outer wall of the embossing roller 22. A dust suction pipe 32 is welded to the outer wall of the support cover 3. The dust suction pipe 32 is connected to the inside of the support cover 3, and a flange is welded to the dust suction pipe 32 away from the outer wall of the support cover 3.

[0033] During use, the base plate 1 provides a stable embossing platform for the device, ensuring embossing accuracy. As the release paper moves between the support roller 14 and the embossing roller 22, the embossing roller 22 can perform embossing on one side of the release paper, ensuring the quality of the texture formation on the release paper surface. During the embossing process, the embossing roller 22 drives the rotating shaft 33 to rotate circumferentially via the turbine 24 and worm gear 34, thereby causing the rubber belt 35 to rotate outside the rotating shaft 33, and due to the brush 36... The embossing roller 22 contacts the outer wall, thus simultaneously removing residual paper scraps, glue stains and other impurities from the roller surface during the embossing process. This ensures the clarity of the embossing groove boundaries on the roller surface of the embossing roller 22, preventing impurities from affecting the embossing quality or causing the release paper to stick. Furthermore, the cleaning is driven by the rotation of the embossing roller 22 itself, eliminating the need for an additional power source and saving energy. The accompanying vacuum cleaner is connected to the flange of the vacuum pipe 32, which can absorb and collect the cleaned and detached impurities, ensuring the cleanliness of the working environment and preventing secondary pollution from impurities.

[0034] For example, to rewind, such as Figure 1 As shown, a support frame 12 is screwed to the outer wall of the base plate 1 on the side away from the fixed frame 11. A take-up roller 13 is installed inside the support frame 12. A motor is installed through the outer wall of one end of the take-up roller 13, and the output end of the motor is connected to the end of the take-up roller 13 by a coupling.

[0035] During use, it is indicated that the support frame 12 can maintain the position of the take-up roller 13, ensuring the stability of the take-up roller 13 in winding the embossed release paper. The motor directly drives the take-up roller 13 through the coupling, and with the matching controller, the winding speed and tension can be precisely controlled. The motor can drive the take-up roller 13 to automatically wind up the release paper after the embossing is completed.

[0036] For guidance, exemplified, such as Figure 2 As shown, guide rods 21 are threadedly connected to both sides of the upper outer wall of the support frame 2, and the guide rods 21 are movably installed inside the fixed frame 11.

[0037] During use, the guide rod 21 restricts the movement direction of the support frame 2, ensuring that it rises and falls smoothly in the vertical direction and avoids deviation during adjustment, thus providing precise guidance for the pressure adjustment of the embossing roller 22 and the release paper.

[0038] To adjust the embossing position, for example, such as Figure 3 As shown, the fixing frame 11 is internally threaded with an adjusting screw 15, and a bearing is interference-fitted on one side of the upper outer wall of the support frame 2. The lower end of the adjusting screw 15 is interference-fitted on the inner ring of the bearing, and the adjusting screw 15 is rotatably connected to the support frame 2 through the bearing.

[0039] In use, rotating the adjusting screw 15 can drive the support frame 2 to move up and down, thereby adjusting the pressure of the embossing roller 22 on the release paper and adjusting the pressing depth of the embossing on the release paper surface. It can adapt to different production requirements. The threaded connection has a self-locking function. After adjusting to the appropriate pressure, no additional locking device is needed, and the pressure can be kept stable.

[0040] To drive embossing, for example, such as Figure 3 As shown, the embossing roller 22 passes through the end of the support frame 2 and is equipped with a drive motor 23. The drive motor 23 is screwed to the outer wall of the support frame 2, and the output end of the drive motor 23 is connected to the end of the embossing roller 22 by a coupling.

[0041] In use, the drive motor 23 can drive the embossing roller 22 to rotate through the coupling, and with the controller, the speed and torque of the embossing roller 22 can be precisely controlled to ensure the clarity and consistency of the embossing pattern. When the drive motor 23 drives the embossing roller 22 to rotate, it can drive the release paper between the support roller 14 and the embossing roller 22 to move, maintaining continuous embossing on the release paper.

[0042] To support the release paper, for example, such as Figure 2 As shown, a support roller 14 is rotatably mounted on one side of the inner wall of the fixed frame 11, and the support roller 14 is located at the lower end of the embossing roller 22.

[0043] When in use, the support roller 14 can lift the release paper, keeping it flat when entering the embossing area, and stabilizing the embossing process of the release paper by the embossing roller 22.

[0044] For synchronized rotation, for example, such as Figure 4 As shown, a worm gear 34 is interference-fitted onto one side of the outer wall of the shaft 33, and two rubber belts 35 are distributed on the upper and lower sides of the screw. The worm gear 34 meshes with the turbine 24.

[0045] When in use, as the embossing roller 22 rotates, the turbine 24 drives the worm gear 34 to rotate, which in turn drives the rotating shaft 33 and the rubber belt 35 to rotate, so that the brush 36 continuously cleans the surface of the embossing roller 22.

[0046] To maintain a stable position, for example, such as Figure 3 As shown, connectors 31 are welded to both sides of the upper outer wall of the support cover 3, and the other end of the connector 31 is screwed to the upper outer wall of the support frame 2.

[0047] During use, connector 31 ensures the positional stability of support cover 3 outside support frame 2, and ensures the stability of brush 36 during the cleaning process.

[0048] When using this utility model, according to the thickness, material and embossing requirements of the release paper, the adjusting screw 15 is rotated, and the support frame 2 is driven to rise and fall vertically in the fixed frame 11 through the bearing. The distance between the embossing roller 22 and the support roller 14 is adjusted, and the appropriate embossing pressure and depth are set. One end of the release paper is pulled out and passed through the support roller 14 and fed into the gap between the support roller 14 and the embossing roller 22.

[0049] Start the drive motor 23, which drives the embossing roller 22 to rotate through the coupling. The friction generated when the embossing roller 22 rotates drives the support roller 14 to rotate synchronously, so that the release paper moves continuously between the two. The texture on the surface of the embossing roller 22 is gradually pressed onto the release paper, completing the single-sided embossing process.

[0050] During the rotation of the embossing roller 22, the turbine 24 connected to its end pin rotates accordingly. The turbine 24 meshes with the worm gear 34 on the rotating shaft 33, causing the rotating shaft 33 to rotate circumferentially, which in turn drives the rubber belt 35 to rotate outside the rotating shaft 33. Since the brush 36 on the outer wall of the rubber belt 35 is in contact with the outer wall of the embossing roller 22, the brush 36 continuously cleans the surface of the embossing roller 22 under the action of the rubber belt 35, removing residual paper scraps, glue stains and other impurities. At the same time, the matching vacuum cleaner is connected through the flange of the vacuum pipe 32 to collect the cleaned and detached impurities.

[0051] After embossing, the release paper continues to move forward and enters the area of ​​the take-up roller 13. The motor is started, and the take-up roller 13 is driven to rotate through the coupling. According to the preset take-up speed and tension, the embossed release paper is automatically wound into a roll.

[0052] It should be noted that this utility model is an embossing mechanism for release paper processing. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
