Description

Technical Field

[0001] This invention relates to the field of release paper preparation technology, specifically to a release paper preparation apparatus and preparation process. Background Technology

[0002] Release paper, also known as silicone paper or anti-stick paper, primarily serves to isolate sticky substances, such as adhesive tape. It generally needs to be peeled off and discarded after use. Its most widespread application is as a carrier for adhesive tapes or other adhesive products. It also has applications in the food and medical industries. Release paper can be classified by whether it's plastic-coated or non-plastic-coated, or by the release agent used: silicone release paper and non-silicone release paper. Plastic-coated release paper requires a plastic coating because the release agent has a certain degree of penetration. Without a barrier, the release agent can penetrate into the paper, causing poor curing and excessive release agent usage, among other problems. In China, polyethylene terephthalate (PET) is commonly used. Ethylene particles are coated, resulting in single-layer and double-layer release papers. Non-plastic release papers include glassine, CCK, and other specially treated release papers. Coated release papers are further divided into single-layer and double-layer. Generally, single-sided release papers are single-layer coated, but double-layered single-sided release papers also exist. Such release papers are relatively smooth. Testing the technical specifications of release papers is a complex process. Generally, electronics factories and tape factories can only test the last few data points. As for the amount of silicone oil coating, this is generally not included in the technical reports of release coating suppliers. The release paper, starting from the bottom layer, consists of: matte PE, double-sided adhesive paper, PE, and release agent. The production of release paper requires repeated pressing operations on multiple structures.

[0003] For example, patent document CN 112761024 B discloses a method for preparing release paper with double-sided coating, including the following preparation steps: applying a first coating material through a first coating head between a first patterned roller and the front surface of the base paper, so that a first coating material layer with a first patterned structure is formed on the front surface of the base paper, thus obtaining base paper with the first coating material layer; applying a second coating material through a second coating head between a second patterned roller and the back surface of the base paper, so that a second coating material layer with a second patterned structure is formed on the back surface of the base paper, thus obtaining release paper with double-sided coating. This invention obtains release paper with double-sided coating by using different coating processes on both sides of the base paper. Because the release paper is wrapped by the double-sided coating, it forms 360-degree protection without dead angles, giving it advantages such as good dustproof, moisture-proof, and wear-resistant properties, greatly expanding the application range of release paper and making it suitable for various fields.

[0004] However, due to its inherent structural limitations, this structure often suffers from poor film adhesion during the initial coating of release paper, leading to film detachment and uneven release paper surface. This results in noticeable uneven film thickness during subsequent repeated coating processes, and the film on the release paper surface cannot be evenly smoothed, affecting the final release paper production quality. Furthermore, the equipment cannot perform efficient and uniform multiple spraying and heating alternating operations on the release paper surface, hindering efficient release paper production. Consequently, when the release paper is used for car wraps and color-changing films, its large area makes it prone to bubbling, failing to meet daily usage requirements. Therefore, there is an urgent need to design a release paper preparation device and process to solve these problems. Summary of the Invention

[0005] The purpose of this invention is to provide a release paper preparation apparatus and process, to solve the problems mentioned in the background art. Due to the limitations of its own structure, the existing structures often experience poor adhesion during the initial coating of release paper, leading to film detachment and uneven release paper surface. This results in significant uneven film thickness on the release paper during subsequent repeated coating processes, and the film on the release paper surface cannot be evenly smoothed, affecting the final release paper production quality. Furthermore, the equipment cannot perform efficient and uniform multiple spraying and heating alternating operations on the release paper surface, hindering efficient release paper production. Consequently, when the release paper is used for car covers and color-changing films, the large area makes it prone to bubbling, failing to meet daily usage requirements.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a release paper preparation apparatus and preparation process, comprising a processing frame, an upper storage frame fixedly connected to the top of the processing frame, a lower storage frame fixedly connected to the bottom of the processing frame, an electric push rod provided on the side of the upper and lower storage frames that are far apart from each other, a lower lifting seat movably connected inside the lower storage frame through the electric push rod, an upper lifting seat movably connected inside the upper storage frame through the electric push rod, connecting seats fixedly connected to both ends of the processing frame, and a support base fixedly connected to the bottom end of the connecting seat;

[0007] The processing frame includes a spray frame and a scraper frame. One end of the processing frame is fixedly connected to the spray frame, and the other end of the processing frame is fixedly connected to the scraper frame. The spray frame has two sets of spray rollers inside, and the scraper frame has two sets of scraper rollers inside. Both ends of the spray rollers and scraper rollers are equipped with ratchet wheels, and the outer surface of the ratchet wheels is fitted with drive gears. Both ends of the spray frame and scraper frame are provided with through slots. The internal structures of the spray frame and scraper frame are the same.

[0008] Preferably, a sliding spray seat is provided between the two sets of spray rollers, a pressing cotton pad is provided on the side of each of the two sets of spray rollers, a cutter seat is provided between the two sets of scraper rollers, and a dust suction grid is provided on the side of each of the two sets of scraper rollers.

[0009] Preferably, a connecting plate is fixedly connected to one end of the spray frame and the scraper frame, and a first material support seat and a second material support seat are fixedly connected to one end of the spray frame and the scraper frame respectively through the connecting plate. A drive roller is provided inside the first material support seat and the second material support seat, and a limit roller is provided on one side of the first material support seat and the second material support seat that are close to each other.

[0010] Preferably, a first limiting frame is provided on one side of the spray frame and the scraper, and a second limiting frame is provided on the other side of the spray frame and the scraper. The first limiting frame and the second limiting frame are provided with upper and lower layers of threaded strips inside.

[0011] Preferably, the second limiting frame has two sliding seats on its back, one above the other, and a drive motor is installed inside the sliding seats.

[0012] Preferably, a first conical seat is uniformly and fixedly connected to the surface of the lower lifting seat, and a second conical seat is uniformly and fixedly connected to the bottom of the upper lifting seat. An inclined spray seat is provided on the side of the first conical seat, and a drying seat is provided on the side of the second conical seat.

[0013] Preferably, the top ends of the first conical seat and the second conical seat are each provided with a first pressing roller, and the surfaces of the lower lifting seat and the upper lifting seat are each provided with a second pressing roller, and the first pressing roller and the second pressing roller are adapted to each other.

[0014] Preferably, the processing frame has lifting slots at its upper and lower ends, feeding slots at its front and rear ends, a movable shaft on one side of the processing frame, and a movable side cover movably connected to the side of the processing frame via the movable shaft.

[0015] S1: Paper feeding, release agent application, coating, drying, and winding. The drive motor inside the sliding seat on the back of the second limit frame is activated, causing the ratchet and drive gear at both ends of the spray roller to rotate. The ratchet and drive gear are stably driven by threaded strips inside the first and second limit frames. At this time, the ratchet allows the two sets of spray rollers to only perform translational movement and not rotate with the drive gears. This causes the sliding spray seat of the spray roller to quickly scrape the coating onto the surface of the release paper, ensuring a more uniform first coat of film on the release paper surface. To ensure the flatness of the subsequent film spraying, when the subsequent spraying roller is reset by the drive gear, the ratchet can release the rotation lock in the opposite direction, allowing the spraying roller to rotate rapidly along the release paper. This allows the release paper to be initially pressed by the pressing cotton pad on the side of the spraying roller. At the same time, when the release paper enters the scraper frame, it is also rapidly moved by two sets of scraper rollers and processed by the pressure roller. However, the joint of the scraper rollers is a cutter seat and a dust collection grid. The cutter seat scrapes off the excess film on the surface of the release paper, and then the waste is sucked out from the dust collection grid, making the processing of the release paper more stable.

[0016] S2: Double-sided coating: Paper feeding, corona treatment, matte PE coating, corona treatment, embossing, PE coating, trimming, and winding. The electric push rods located at the upper and lower ends of the upper and lower storage frames are activated, causing the lower and upper lifting seats to dock towards the center of the processing frame. After docking, the first and second conical seats, with their offset design, quickly press the release paper inside the processing frame. The first and second pressing rollers then provide stable, wavy pressure, increasing the overall pressure force. Simultaneously, the inclined spray station on the side of the first conical seat sprays the release paper surface repeatedly, followed by repeated pressing by the first and second pressing rollers. The drying station on the side of the second conical seat performs repeated drying operations, allowing the equipment to complete multiple coating processes within the processing frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The release paper preparation device and process, through the setting of a processing frame, spray frame, scraper frame, spray roller, scraper roller, ratchet, drive gear, through slot, sliding spray seat, pressing cotton pad, cutter seat, dust collection grid, connecting plate, first material support seat, second material support seat, drive roller, limiting roller, first limiting frame, second limiting frame, threaded strip, sliding seat and drive motor, enables the equipment to perform a more uniform and stable double-sided spraying operation of the release paper. In actual use, the operator first puts the roll of release paper to be used into the first material support seat. The release paper is then pulled out and passed through the spray frame, processing frame, and scraper frame, finally being wound up inside the second support seat. Normally, the release paper can be quickly wound and unwound by controlling the drive rollers inside the first and second support seats, allowing for rapid processing and adjustment, improving the equipment's release paper processing control effect. Once the release paper enters the spray frame, it is quickly clamped by two sets of spray rollers inside the frame. At this point, the drive motor on the back of the second limit frame inside the sliding seat can be activated to drive the spray... The ratchet and drive gear at both ends of the roller rotate. The ratchet and drive gear are stably driven by threaded strips inside the first and second limit frames. At this time, the ratchet allows the two sets of spray rollers to only translate, without rotating with the drive gear. This causes the sliding spray seat of the spray roller to quickly scrape the coating onto the surface of the release paper, ensuring a more uniform first coat of film on the release paper surface, thus guaranteeing smoothness during subsequent film spraying. When the subsequent spray rollers are reset by the drive gear, the ratchet can be released in the opposite direction. In addition to the rotation lock, the spray rollers rotate rapidly along the release paper, thus performing an initial pressing operation on the release paper through the pressing cotton pads on the side of the spray rollers. At the same time, when the release paper enters the scraper frame, it is also rapidly moved by two sets of scraper rollers for processing on the pressure rollers. However, the joint between the scraper rollers is a cutter seat and a dust collection grid. The cutter seat scrapes off the excess film on the surface of the release paper, and then the waste is sucked out from the dust collection grid. This makes the processing of the release paper more stable and ensures the quality of the release paper at every position, reflecting the practicality of the equipment design.

[0019] The release paper preparation device and process, through the setting of a processing frame, upper storage frame, lower storage frame, electric push rod, lower lifting seat, upper lifting seat, connecting seat, support base, first conical seat, second conical seat, inclined spray seat, drying seat, first pressing roller, second pressing roller, lifting channel, feeding channel, movable shaft, and movable side cover, further improves the overall use efficiency of the equipment. In daily use, the operator first quickly opens the movable side cover on the side of the processing frame along the movable shaft, then inserts and exits the release paper through the feeding channels at both ends of the processing frame. Afterwards, the electric push rods located at the upper and lower ends of the upper and lower storage frames can be activated, causing them to drive the lower and upper lifting seats to dock towards the center of the processing frame. After completion, the first and second conical seats, with their staggered surface design, allow for rapid vertical contact of the release paper inside the processing frame. The first and second pressing rollers then provide stable, wavy pressure, increasing overall pressure. Simultaneously, the inclined spray station on the side of the first conical seat sprays the release paper surface repeatedly, followed by repeated pressing by the first and second pressing rollers. The drying station on the side of the second conical seat performs repeated drying operations. This allows the equipment to complete multiple repeated coating processes within the processing frame, adjusting thickness, depth, texture spacing, and featuring air guide grooves for ventilation and air circulation. This significantly improves the overall performance of the equipment, demonstrating the comprehensiveness of its design. Attached Figure Description

A second pressing roller 35 is provided on the surface of both the lower lifting seat 5 and the upper lifting seat 6. The first pressing roller 34 and the second pressing roller 35 are mutually compatible. Lifting grooves 36 are provided at the upper and lower ends of the processing frame 1. Feeding grooves 37 are provided at the front and rear ends of the processing frame 1. A movable shaft 38 is provided on one side of the processing frame 1. A movable side cover 39 is movably connected to the side of the processing frame 1 through the movable shaft 38.

[0032] The spray frame 9 and scraper frame 10 are fixedly connected to one end of the processing frame 1 and the scraper frame 10 is fixedly connected to the other end of the processing frame 1. The spray frame 9 has two sets of spray rollers 11 inside, and the scraper frame 10 has two sets of scraper rollers 12 inside. Both ends of the spray rollers 11 and scraper rollers 12 are equipped with ratchet wheels 13, and drive gears 14 are sleeved on the outer surface of the ratchet wheels 13. Through slots 15 are opened at both ends of the spray frame 9 and scraper frame 10. The internal structures of the spray frame 9 and scraper frame 10 are identical. A sliding spray seat 16 is provided between the two sets of spray rollers 11. Pressing cotton pads 17 are provided on the sides of both sets of spray rollers 11. A cutter seat 18 is provided between the two sets of scraper rollers 12. Dust collection grilles 19 are provided on the sides of both sets of scraper rollers 12. A connecting plate 20 is fixedly connected to one end of the spray frame 9 and the scraper frame 10. A first material support seat 21 and a second material support seat 22 are fixedly connected to one end of the spray frame 9 and the scraper frame 10 respectively through the connecting plate 20. A drive roller 23 is provided inside the first material support seat 21 and the second material support seat 22. A limiting roller 24 is provided on one side of the first material support seat 21 and the second material support seat 22 close to each other. A first limiting frame 25 is provided on one side of the spray frame 9 and the scraper frame 10. A second limiting frame 26 is provided on the other side of the spray frame 9 and the scraper frame 10. Threaded strips 27 are provided in the upper and lower layers inside the first limiting frame 25 and the second limiting frame 26. Sliding seats 28 are provided in the upper and lower layers on the back of the second limiting frame 26. A drive motor 29 is provided inside the sliding seat 28.

[0033] S1: Paper feeding, release agent application, coating, drying, and winding. The drive motor 29, located inside the sliding seat 28 on the back of the second limiting frame 26, is activated, causing the ratchet 13 and drive gear 14 at both ends of the spray roller 11 to rotate. The ratchet 13 and drive gear 14 are stably driven to rotate within the first limiting frame 25 and the second limiting frame 26 via a threaded strip 27. However, at this time, the ratchet 13 allows the two sets of spray rollers 11 to only perform translational movement and not rotate with the drive gear 14. This causes the sliding spray seat 16 of the spray roller 11 to quickly scrape the coating onto the surface of the release paper, ensuring a more uniform first coat of film on the release paper surface. To ensure the flatness of the subsequent film spraying, when the subsequent spray roller 11 is reset by the drive gear 14, the ratchet 13 can be released in the opposite direction to unlock the rotation, so that the spray roller 11 can rotate quickly along the release paper. Thus, the release paper is initially pressed by the pressing cotton pad 17 on the side of the spray roller 11. At the same time, when the release paper enters the scraper frame 10, it is also quickly moved by two sets of scraper rollers 12 and processed by the pressure roller. However, the joint of the scraper rollers 12 is the cutter seat 18 and the dust collection grid 19. The cutter seat 18 scrapes off the excess film on the surface of the release paper, and then the waste is sucked out from the dust collection grid 19, so that the processing of the release paper is more stable.

[0034] S2: Double-sided coating: Paper feeding, corona treatment, matte PE coating, corona treatment, embossing, PE coating, trimming, winding. The electric push rods 4 located at the upper and lower ends of the upper and lower storage racks 2 and 3 are activated, causing them to drive the lower lifting seat 5 and upper lifting seat 6 to dock towards the center of the processing frame 1. After docking, the first conical seat 30 and the second conical seat 31, with their surfaces offset, can quickly push the release paper inside the processing frame 1 together. The first pressing roller 34 and the second pressing roller 35 enable the release paper to undergo stable up-and-down wavy pressing operations, improving the overall up-and-down pressing force. At the same time, the inclined spray seat 32 on the side of the first conical seat 30 sprays the release paper surface repeatedly, and then it is pressed repeatedly by the first pressing roller 34 and the second pressing roller 35. The drying seat 33 on the side of the second conical seat 31 can perform repeated drying operations, so that the equipment can complete multiple repeated coating production operations inside the processing frame 1.

[0035] Working principle: During use, the operator first places the release paper roll into the first support seat 21, then pulls it out, passing it through the spray frame 9, processing frame 1, and scraper frame 10, finally winding it up inside the second support seat 22. Normally, the release paper can be quickly wound up and unwound by controlling the drive rollers 23 inside the first and second support seats 21 and 22, allowing for rapid processing and adjustment, improving the processing control effect of the equipment. When the release paper enters the spray frame 9, it is quickly clamped by the two sets of spray rollers 11 inside the spray frame 9. At this time, the drive motor 29 on the back of the second limit frame 26, located inside the sliding seat 28, can be activated to drive it... The ratchet 13 and drive gear 14 at both ends of the rotating spray roller 11 rotate. The ratchet 13 and drive gear 14 are stably driven to rotate inside the first limit frame 25 and the second limit frame 26 by the threaded strip 27. At this time, the ratchet 13 allows the two sets of spray rollers 11 to only perform translational movement and not rotate with the drive gear 14. Then, the sliding spray seat 16 of the spray roller 11 quickly scrapes the coating on the surface of the release paper, thereby ensuring that the first layer of film on the surface of the release paper is more uniform, so as to ensure the flatness of the subsequent film spraying. When the spray roller 11 is reset by the drive gear 14, the ratchet 13 can be released in the opposite direction to release the rotation lock, so that the spray roller 11 rotates quickly along the release paper. The process involves initial pressing of the release paper using the pressing pads 17 on the side of the spray roller 11. Simultaneously, as the release paper enters the scraper frame 10, it is rapidly moved across the pressure rollers by two sets of scraper rollers 12. The scraper rollers 12 are joined by a cutter seat 18 and a dust collection grid 19. The cutter seat 18 scrapes away excess film from the surface of the release paper, and the waste is then sucked out from the dust collection grid 19. This ensures more stable processing of the release paper and guarantees the quality of each position. In daily use, the operator first quickly opens the movable side cover 39 along the movable shaft 38 on the side of the processing frame 1, and then inserts and exits the release paper through the feeding channels 37 at both ends of the processing frame 1. After operation, the electric push rods 4 located at the upper and lower ends of the upper and lower storage racks 2 and 3 can be activated to drive the lower lifting seat 5 and the upper lifting seat 6 to dock towards the center of the processing frame 1. After docking, the first conical seat 30 and the second conical seat 31, which are designed with a staggered surface on the lower lifting seat 5 and the upper lifting seat 6, can quickly push the release paper inside the processing frame 1 up and down. The first pressing roller 34 and the second pressing roller 35 can make the release paper perform a stable up and down wave-shaped pressing operation, improving the overall up and down pressing force. At the same time, the inclined spray seat 32 on the side of the first conical seat 30 sprays the surface of the release paper repeatedly, and then the first pressing roller 34 and the second pressing roller 35 press it repeatedly.Furthermore, the drying seat 33 on the side of the second conical seat 31 can perform repeated drying operations, allowing the equipment to complete multiple repeated coating production operations within the processing frame 1, greatly improving the overall performance of the equipment. The above summarizes the entire working principle of this invention.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
