Description

Technical Field

[0001] This invention relates to the field of release paper production equipment, specifically to a coating and laminating equipment for producing release paper and its control method. Background Technology

[0002] Release paper, also known as silicone paper, anti-stick paper, barrier paper, etc., mainly serves to isolate sticky objects, such as tape. It generally needs to be peeled off and discarded during use. It is now widely used as a carrier for tape or adhesive products, and it is also used in the food and medical hygiene industries.

[0003] In the production process of release paper, coating equipment is used to apply an adhesive release agent to the surface of the base paper. During the application of the release agent, there are many factors that affect its application, such as the tension control of the base paper during transport. Insufficient tension of the base paper during transport will cause wrinkles to appear on the base paper when it is transported to the release agent coating position and during the winding process, thus affecting the coating effect of the release agent and the winding effect of the release paper.

[0004] In addition, the release agent coating effect is one of the factors affecting the quality of the finished release paper. The thickness of the release agent coating on the entire base paper needs to be basically consistent so that the overall drying effect can be achieved within the same drying time during the subsequent drying process. If the release agent coating is uneven, the produced release paper may have performance defects during use. To address this, some coating devices with doctor blades have been designed to deal with the situation of excessive release agent coating on the surface of the base paper. However, after the doctor blade scrapes off the release agent, some residue remains on the doctor blade. If it is not collected, the release agent will adhere to the surface of the doctor blade and affect the operation of the doctor blade.

[0005] Therefore, it is necessary to design a coating and laminating equipment and its control method for producing release paper. Summary of the Invention

[0006] To address the shortcomings of the aforementioned technologies, this invention provides a leveling mechanism that levels the base paper conveyed to the coating roller, ensuring that the release agent is applied to the base paper in a fully open state. Furthermore, the cutting blades of the cutting roller scrape away excess release agent from the surface of the base paper, ensuring uniform release agent application and consistent drying effect across all areas of the base paper surface. This invention also discloses a control method for the coating and laminating equipment used in producing release paper. This method controls the tension of the base paper during transport and the amount of release agent applied to the base paper surface, ensuring stable quality of the release paper.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: This invention discloses a coating and laminating equipment for producing release paper, comprising a base, with an unwinding mechanism and a rewinding mechanism respectively located at the front and rear ends of the base. A coating roller is connected to the base behind the unwinding mechanism via a rotating shaft, and a support roller is connected to the base below the coating roller via a rotating shaft. A leveling mechanism is located in the space between the support roller and the unwinding mechanism. A cutting roller is located in the base behind the coating roller, with spiral cutting blades on its surface. Lifting mechanisms are connected to both ends of the cutting roller, and the lifting mechanisms are fixed to the left and right walls of the base. A coating recovery mechanism is located on the base wall outside one side of the lifting mechanism. A tensioning roller is located in the base behind the cutting roller, and a drying device is located above the tensioning roller.

[0008] Furthermore, the unwinding mechanism has the same structure as the winding mechanism. The unwinding mechanism includes a first cylinder, a support frame, a first motor, and a paper roll. The first cylinder is respectively located on the left and right sides of the front end of the machine base. The output end of the first cylinder faces upward and is connected to the bottom end of the support frame. The first motor is fixed on the top surface of one of the support frames on the left and right sides of the machine base. The front and rear ends of the machine base are provided with first openings. Both ends of the paper roll extend outside the first openings. One end of the paper roll is connected to the output end of the first motor. The top surface of the other support frame is provided with a paper roll fixing seat for fixing the end of the paper roll.

[0009] Furthermore, the leveling mechanism includes a second cylinder, a connecting plate, and a paper-pressing roller. The second cylinder is respectively located on the left and right sides of the front end of the machine base. The output end of the second cylinder faces upward and is connected to the bottom end of the connecting plate. The front and rear ends of the machine base are provided with second openings. The top part of the connecting plate gradually bends from the outside of the second opening to the inside of the second opening. The height of the top part of the connecting plate gradually decreases from the outside of the second opening to the inside of the second opening. The paper-pressing roller is fixed to the end of the connecting plate located inside the machine base by a rotating shaft. The diameter of the paper-pressing roller continuously decreases from the middle of the paper-pressing roller to the end face of the paper-pressing roller.

[0010] Furthermore, the lifting mechanism includes a lead screw, a second motor, guide rods, a lifting seat, and a third motor. The machine base has third openings on both the left and right sides of its center. Two lead screw fixing seats, vertically opposite each other, are located on the outer wall of the machine base outside one of the third openings. Both ends of the lead screw are fitted into the lead screw fixing seats. The second motor is fixed to one of the lead screw fixing seats, and its output end is connected to the input end of the lead screw. A guide rod fixing seat is located on the outer wall of the machine base below the third opening. At least two guide rods are fixedly connected to the front and rear sides of the third opening. The lifting seat engages with the guide rods through mating holes at both ends. The side wall of the lifting seat is fixedly connected to the nut of the lead screw. Both ends of the cutting roller are fitted to the center of the lifting seat through bearings. One end of the lifting seat has a support plate. The third motor is mounted on the surface of the support plate, and its output end is connected to one end of the cutting roller.

[0011] Furthermore, the paint recycling mechanism includes a paint collection device, a material transfer pipe, and a scraper end. Fixing frames are provided on both the left and right outer walls of the middle section of the machine base. The paint collection device is located on the outer wall of the machine base outside one side of the fixing frame. The output end of the material transfer pipe is connected to the top of the paint recycling mechanism. The material transfer pipe extends from the outside of the machine base to the inside. The material transfer pipe is fixed in position by fixing components connected to the fixing frames. The scraper end is connected to the input end of the material transfer pipe. The scraper end is Y-shaped, and two ends of the forked portion are provided with scraper sections. The scraper sections are bucket-shaped, and the inner walls on both sides of the scraper section are inclined surfaces that slope away from the opening of the scraper section, with the height continuously increasing.

[0012] Furthermore, a three-way electric valve is provided in the middle section of the material transfer pipe, and one of the ports of the three-way electric valve is provided with an air inlet.

[0013] This invention also discloses a control method for a coating and laminating equipment used in the production of release paper. The control method for the aforementioned coating and laminating equipment includes the following steps: Step 1: The base paper is released from the unwinding mechanism and transferred between the coating roller and the idler roller. The leveling mechanism squeezes the base paper to keep it taut. Step 2: The coating roller applies a release agent to the surface of the base paper; Step 3: The base paper is transferred from the coating roller and the support roller to the cutting roller. The cutting blades in the cutting roller scrape off the excessive release agent coating on the surface of the base paper. The coating recovery mechanism collects the release agent adhering to the surface of the cutting blades. Step 4: The drying device dries the release agent on the surface of the base paper; Step 5: The paper is transferred by rollers to the winding mechanism for winding.

[0014] Furthermore, in step one, both the unwinding mechanism and the leveling mechanism acting on the surface of the base paper can be height adjusted.

[0015] Furthermore, in step three, the cutting blade moves the excessively thick release agent coating on the surface of the original paper to the surface of the original paper near the scraping position, filling in the part of the original paper surface that lacks release agent coating.

[0016] Furthermore, in step five, the winding mechanism portion acting on the surface of the base paper can be height adjusted.

[0017] The beneficial effects of this invention are as follows: In a coating and laminating device for producing release paper disclosed in this invention, a leveling mechanism can level the base paper conveyed to the coating roller, ensuring that the release agent is applied to the base paper in a fully open state; the cutting blade of the cutting roller can scrape off excess release agent from the surface of the base paper, ensuring uniform application of release agent and consistent drying effect of release agent at various locations on the surface of the base paper; the coating recovery mechanism can collect and reuse excess release agent scraped off by the cutting roller, achieving the purpose of saving materials and reducing production costs; the height of the cutting roller can be adjusted by the lifting mechanism, changing the position between the cutting blade and the base paper conveying path, allowing the cutting roller to adapt to the production needs of release paper of different thicknesses; in addition, when the winding mechanism winds up the dried release paper, it can adjust the tension of the release paper when it is conveyed to the winding mechanism by adjusting its own height, keeping the release paper taut during winding and preventing wrinkles from forming during winding.

[0018] The present invention also discloses a control method for a coating and laminating equipment for producing release paper. This control method can control the tension of the base paper during the transmission process and the amount of release agent applied to the surface of the base paper, thereby ensuring the stable quality of the release paper.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, this invention discloses a coating and laminating equipment for producing release paper, including a base 1. An unwinding mechanism 2 and a rewinding mechanism 3 are respectively provided at the front and rear ends of the base 1. A coating roller 4 is connected to the base 1 behind the unwinding mechanism 2 via a rotating shaft. A support roller 5 is connected to the base 1 below the coating roller 4 via a rotating shaft. A leveling mechanism 6 is provided in the space between the support roller 5 and the unwinding mechanism 2. A cutting roller 7 is provided in the base 1 behind the coating roller 4. The surface of the cutting roller 7 is provided with spiral cutting blades 8. Lifting mechanisms 9 are connected to both the left and right ends of the cutting roller 7. The lifting mechanisms 9 are fixed to the left and right walls of the base 1. A coating recovery mechanism 10 is provided on the wall of the base 1 outside one side of the lifting mechanism 9. A tension roller 11 is provided in the base 1 behind the cutting roller 7. A drying device 12 is provided above the tension roller 11.

[0031] Among them, the leveling mechanism 6 can level the raw paper that is conveyed to the coating roller 4, ensuring that the release agent is applied to the raw paper in a fully open state. During rotation, the shearing roller 7 scrapes off excess release agent from the surface of the base paper using the shearing blades 8, ensuring a uniform amount of release agent and consistent drying effect across the entire surface. Simultaneously, the shearing blades 8 move excess release agent to adjacent scraping locations, filling in areas lacking release agent or with insufficient thickness, thus maintaining a consistent release agent coating thickness. The coating recovery mechanism 10 can scrape off excess release agent from the shearing roller 7. The release agent is collected and reused to save materials and reduce production costs. The height of the cutting roller 7 is adjusted by the lifting mechanism 9, which changes the position between the cutting blade 8 in the cutting roller 7 and the raw paper transport path, so that the cutting roller 7 can adapt to the production needs of release paper of different thicknesses. In addition, when the winding mechanism 3 winds up the dried release paper, it can adjust the tension of the release paper when it is transported to the winding mechanism 3 by adjusting its own height, so that the release paper is kept taut during winding and wrinkles are prevented from forming during winding.

[0032] like Figure 1 and Figure 4 As shown, the unwinding mechanism 2 and the winding mechanism 3 have the same structure. The unwinding mechanism 2 includes a first cylinder 13, a support frame 14, a first motor 15, and a paper roll 16. The first cylinder 13 is respectively arranged on the left and right sides of the front end of the machine base 1. The output end of the first cylinder 13 faces upward and is connected to the bottom end of the support frame 14. The first motor 15 is fixed on the top surface of one of the support frames 14 on the left and right sides of the machine base 1. The front and rear ends of the machine base 1 are provided with first openings. Both ends of the paper roll 16 extend outside the first openings. One end of the paper roll 16 is connected to the output end of the first motor 15. The top surface of the other support frame 14 is provided with a paper roll fixing seat 17 for fixing the end of the paper roll 16.

[0033] In the unwinding mechanism 2, the first motor 15 drives the paper roll 16 to rotate, which enables the unwinding operation of the raw paper. In the winding mechanism 3, the first motor 15 drives the paper roll 16 to rotate, which enables the winding operation of the release paper. The support frame 14 is moved up and down by the first cylinder 13, which can adjust the height of the paper roll 16. After the height of the paper roll 16 is adjusted, the unwinding height of the raw paper by the unwinding mechanism 2 will change, thereby changing the tension when the raw paper is transferred between the coating roller 4 and the support roller 5.

[0034] like Figure 1 and Figure 5As shown, the leveling mechanism 6 includes a second cylinder 18, a connecting plate 19, and a paper-pressing roller 20. The second cylinder 18 is respectively located on the left and right sides of the front end of the machine base 1. The output end of the second cylinder 18 faces upward and is connected to the bottom end of the connecting plate 19. The front and rear ends of the machine base 1 are provided with second openings. The top part of the connecting plate 19 gradually bends from the outside of the second opening to the inside of the second opening. The height of the top part of the connecting plate 19 gradually decreases from the outside of the second opening to the inside of the second opening. The paper-pressing roller 20 is fixed to the end of the connecting plate 19 located in the machine base by a rotating shaft. The diameter of the paper-pressing roller 20 continuously decreases from the middle of the paper-pressing roller 20 to the end face of the paper-pressing roller 20.

[0035] The second cylinder 18 can drive the connecting plate 19 to move up and down, thereby adjusting the height of the pressure roller 20 and adjusting the position of the pressure roller pressing the paper. This allows the pressure roller 20 to adapt to the paper transfer position after the unwinding mechanism 2 adjusts the unwinding height. The edges on both sides of the pressure roller 20 press against the surface of the paper. Since the edges on both sides of the pressure roller 20 are a 35-degree slope transition, the force-bearing area when the edges of the pressure roller 20 press against the surface of the paper will increase, thereby dispersing the force and preventing damage to the surface of the paper while applying external force to it.

[0036] like Figure 1 and Figure 7 As shown, the lifting mechanism 9 includes a lead screw 21, a second motor 22, a guide rod 23, a lifting seat 24, and a third motor 25. The base 1 has third openings on both the left and right sides of its central portion. Two vertically opposite lead screw fixing seats 26 are provided on the outer wall of the base 1 outside one of the third openings. The two ends of the lead screw 21 are fitted into the lead screw fixing seats 26. The second motor 22 is fixed to one of the lead screw fixing seats 26, and its output end is connected to the input end of the lead screw 21. The outer wall of the base 1 below the third opening is provided with… There is a guide rod fixing seat 27, which fixes at least two guide rods 23 located on the front and rear sides of the third opening respectively. The lifting seat 24 is engaged with the guide rods 23 through the mating holes at both ends. The side wall of the lifting seat 24 is fixedly connected to the nut of the lead screw 21. The two ends of the cutting roller 7 are engaged with the middle of the lifting seat 24 through bearings. One end of the lifting seat 24 is provided with a support plate 28. The third motor 25 is disposed on the surface of the support plate 28. The output end of the third motor 25 is connected to one end of the cutting roller 7.

[0037] The second motor 22 can drive the lead screw 21 to work, thereby driving the lifting seat 24 to move up and down on the guide rod 23, thereby adjusting the height of the cutting roller 7 so that the cutting roller 7 can adapt to the production needs of release paper of different thicknesses.

[0038] like Figure 8 and Figure 9 As shown, the paint recycling mechanism 10 includes a paint collecting device 29, a material transfer pipe 30, and a scraper end 31. Fixing frames 32 are provided on the left and right outer walls of the middle part of the machine base 1. The paint collecting device 29 is located on the outer wall of the machine base 1 outside one side of the fixing frame 32. The output end of the material transfer pipe 30 is connected to the top of the paint recycling mechanism 10. The material transfer pipe 30 extends from the outside of the machine base 1 towards the inside of the machine base 1. The material transfer pipe 30 is fixed in position by fixing members 33 connected to the fixing frame 32. The scraper end 31 is connected to the input end of the material transfer pipe 30. The scraper end 31 is Y-shaped, and two ends of the forked portion are provided with scraper parts 34. The scraper parts 34 are bucket-shaped, and the inner walls on both sides of the scraper parts 34 are inclined surfaces 35 that slope away from the opening of the scraper parts 34 and whose height continuously increases.

[0039] Among them, the Y-shaped scraper end 31 is located on both sides of the cutting blade 8. During the rotation of the cutting roller 7, the scraper part 34 scrapes off the release agent remaining on the surface of the cutting roller 7. The release agent collected by the scraper part 34 will continuously accumulate at the opening of the scraper part 34 and will be continuously transported to the scraper end 31 away from the scraper part 34 under the guidance of the inclined surface 35. The release agent will be continuously transported into the material transfer pipe 30 until the release agent enters the paint collection device 29 for collection.

[0040] like Figure 8 As shown, a three-way electric valve 36 is provided in the middle section of the material transfer pipe 30, and one of the ports of the three-way electric valve 36 is provided with a venting interface 37.

[0041] The device is connected to an external jetting device (not shown in the figure) via a venting interface 37. After the venting interface 37 is connected to the material transfer pipe 30 via a three-way electric valve 36, the jetting device blows air into the material transfer pipe 30 to blow out the release agent remaining in the material transfer pipe 30, thus preventing the release agent remaining in the material transfer pipe 30 from affecting the recovery of the release agent in the material transfer pipe 30.

[0042] like Figure 10 As shown, the present invention also discloses a control method for a coating and laminating equipment for producing release paper, the control method for the aforementioned coating and laminating equipment, the control method comprising the following steps: Step 1: The base paper is released from the unwinding mechanism and transferred between the coating roller and the idler roller. The leveling mechanism squeezes the base paper to keep it taut. Step 2: The coating roller applies a release agent to the surface of the base paper; Step 3: The base paper is transferred from the coating roller and the support roller to the cutting roller. The cutting blades in the cutting roller scrape off the excessive release agent coating on the surface of the base paper. The coating recovery mechanism collects the release agent adhering to the surface of the cutting blades. Step 4: The drying device dries the release agent on the surface of the base paper; Step 5: The paper is transferred by rollers to the winding mechanism for winding.

[0043] This control method can control the tension of the base paper during the transport process and the amount of release agent applied to the surface of the base paper, thus ensuring the stable quality of the release paper.

[0044] like Figure 10 As shown, in step one, both the unwinding mechanism and the leveling mechanism acting on the surface of the base paper can be height adjusted.

[0045] The tension of the paper during the transfer of the paper to the release agent coating position can be adjusted by the unwinding mechanism and the leveling mechanism. This allows the paper to remain open as much as possible during the release agent coating process, which helps the release agent to be coated more evenly on the paper surface.

[0046] like Figure 10 As shown, in step three, the cutting blade moves the excessively thick release agent coating on the surface of the original paper to the surface of the original paper near the scraping position, filling in the part of the original paper surface that lacks release agent coating.

[0047] Among them, the cutting blade can automatically fill the part of the base paper surface that lacks release agent coating with release agent, so that the release agent coating on the base paper surface is more uniform and ensures the forming effect of the release agent on the base paper surface after drying.

[0048] like Figure 10 As shown, in step five, the winding mechanism portion acting on the surface of the base paper can be height adjusted.

[0049] The height adjustment of the part of the winding mechanism that acts on the surface of the base paper can change the tension of the release paper transmitted between the tension roller and the winding mechanism, so that the release paper wound by the winding mechanism is kept as taut as possible, and wrinkles are avoided during the winding process.

[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
