Description

Technical Field

[0001] This utility model mainly relates to the technical field of standard hot-pressed paper processing, specifically an automatic bonding device for release paper processing. Background Technology

[0002] Automatic laminating machines for release paper processing play a vital role in industrial production. They enable rapid and continuous lamination operations, significantly improving production efficiency. Compared to traditional manual lamination methods, automatic laminating machines can complete hundreds of lamination operations per minute, greatly shortening the production cycle and reducing labor costs. However, during operation, the pressure rollers of automatic laminating machines are under constant high pressure, which can easily lead to vertical misalignment, resulting in deviations in the lamination thickness of the subsequent finished release paper. To eliminate this issue, an automatic laminating device for release paper processing with uniform pressure is needed.

[0003] According to application number 201920735620.8, a back release paper bonding device for hot pressing paper processing includes a base, a first motor, and a second motor. A left column and a right column are respectively arranged on the left and right sides of the base. The first motor is arranged on the right side of the right column, and the output end of the first motor is connected to a first roller shaft. A fixed roller is arranged on the front side of the first roller shaft, and a third roller shaft is arranged on the front side of the fixed roller. The third roller shaft is connected to the output end of the second motor. The second motor is arranged on the left side of the left column. A pressure plate is fixed at the bottom of the fixing member, and a locking block is arranged on both the left and right sides of the fixing member.

[0004] The aforementioned document states that by using a pressure plate with a length equal to that of a fixed roller, the pressure plate and release paper can be pressed tightly together during the bonding of the hot-pressed paper and the release paper, thereby making the bond between the release paper and the hot-pressed paper tighter and improving the yield rate. However, it cannot solve the problem of inconsistent quality caused by pressure changes during bonding. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an automatic bonding device for release paper processing to solve the technical problems mentioned in the background art.

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

[0007] An automatic laminating device for release paper processing includes a guide rail, two support plates vertically disposed at one end of the guide rail, a loading plate disposed at the top of the middle part of the guide rail, two lower pressure rollers rotatably disposed in the middle of the guide rail, an upper pressure roller disposed at the top of the lower pressure rollers, driving components disposed at both ends of the lower pressure rollers, a heating cover disposed at the bottom of the lower pressure rollers, lifting components disposed at both ends of the upper pressure rollers, and a pressurizing component disposed at the top of the loading plate.

[0008] Preferably, the support plate includes a first winding wheel located at the bottom center and a second winding wheel located at the top center.

[0009] Preferably, the guide rail includes two limiting wheels located on both sides near one end of the support plate.

[0010] Preferably, the driving component includes a dual-output reducer located on one side outside the guide rail and with its output end connected to the central shafts of the two lower pressure rollers respectively, and a first motor connected to the input end of the dual-output reducer.

[0011] Preferably, the heating cover includes multiple heating tubes disposed on the inner side, a temperature controller disposed at the bottom of the heating cover to control the temperature, and an electronic thermometer disposed below the loading plate.

[0012] Preferably, the lifting component includes movable grooves on both sides of the guide rail, a threaded rod inside the movable groove, and a threaded cylinder connected to the threaded rod and rotatably connected to one end of the upper pressure roller by a nut.

[0013] Preferably, the pressurizing component includes a four-output reducer located at the center of the top of the loading plate, a second motor whose execution end is connected to the input end of the four-output reducer, a worm gear located at the top of the threaded rod, a worm connected at one end to the worm gear and at the other end to the output shaft of the four-output reducer, and a thickness gauge located at the discharge end of the guide rail.

[0014] In summary, this technical solution has the following main advantages:

[0015] This invention uses a temperature controller to independently control the heating element inside the temperature hood, which heats the lower pressure roller and then heats the base paper and the film to be laminated through heat conduction, improving their bonding performance. An electronic thermometer detects the temperature in real time and feeds the signal back to the temperature controller. The temperature controller adjusts the temperature of the heating element in a timely manner according to the temperature deviation to achieve temperature compensation, thereby improving the yield.

[0016] By employing a pressure-adjusting component, and utilizing the cooperation of a second motor, a four-output reducer, a worm gear, a worm wheel, and a threaded rod, the bonding pressure is adjusted based on the thickness of the finished release paper measured by a thickness gauge. If the finished product is too thick, the pressure is increased to make subsequent finished products thinner; conversely, if the finished product is too thin, the pressure is decreased to make subsequent finished products thicker. This pressure adjustment mechanism ensures that the overall thickness of the finished release paper meets design standards. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example

[0027] Please refer to the attached document carefully. Figure 1 , 2As shown in Figures 3 and 4, an automatic laminating device for release paper processing includes a guide rail 10, two support plates 11 vertically disposed at one end of the guide rail 10, a loading plate 12 disposed at the top of the middle part of the guide rail 10, two lower pressure rollers 13 rotatably disposed in the middle of the guide rail 10, an upper pressure roller 14 disposed at the top of the lower pressure rollers 13, driving components 15 disposed at both ends of the lower pressure rollers 13, a heating cover 16 disposed at the bottom of the lower pressure rollers 13, lifting components 17 disposed at both ends of the upper pressure rollers 14, and a loading plate 12 disposed at the top of the guide rail 10. The carrier plate 12 has a pressure component 18 at the top; the support plate 11 includes a first winding wheel 111 at the bottom of the middle section and a second winding wheel 112 at the top of the middle section; the guide rail 10 includes two limiting wheels 101 on both sides near one end of the support plate 11; the drive component 15 includes a dual-output reducer 151 located on one side outside the guide rail 10 and whose output ends are respectively connected to the central shafts of the two lower pressure rollers 13, and a first motor 152 whose execution end is connected to the input end of the dual-output reducer 151.

[0028] As described above, the release paper base paper is wound on the first winding wheel 111, and the release paper film to be applied is wound on the second winding wheel 112. The two limiting wheels 101 are responsible for aligning the ends of the base paper and the film to be applied to prevent misalignment. After the base paper and the film to be applied are properly pulled, the first motor 152 starts and provides a large torque in the same direction to the two lower pressure rollers 13 through the dual output reducer 151. The rotation of the lower pressure rollers 13 drives the base paper and the film to be applied to move forward to the discharge end.

[0029] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 5, 6, and 7, the heating hood 16 includes multiple heating tubes 161 located on its inner side, a temperature controller 162 located at the bottom of the heating hood 16 to control the temperature, and an electronic thermometer 163 located below the loading plate 12; the lifting component 17 includes movable grooves 171 located on both sides of the guide rail 10, a threaded rod 172 located inside the movable grooves 171, and a threaded cylinder 173 connected to the threaded rod 172 and rotatably connected to one end of the upper pressure roller 14 by a nut; the pressurizing component 18 includes a four-output reducer 181 located at the top center of the loading plate 12, a second motor 182 whose execution end is connected to the input end of the four-output reducer 181, a worm gear 183 located at the top of the threaded rod 172, a worm 184 connected at one end to the worm gear 183 and at the other end to the output shaft of the four-output reducer 181, and a thickness gauge 185 located at the discharge end of the guide rail 10.

[0030] As described above, the lower pressure roller 13 is made of a metal with good thermal conductivity. The temperature controller 162 can independently control the temperature of the heating tubes 161 in different heating covers 16. When the release paper is being laminated, the temperature controller 162 controls the heating tubes 161 in the heating cover 16 to start, heating the corresponding lower pressure roller 13. The heated lower pressure roller 13 heats the lower surface of the backing paper, and through heat conduction, the film to be laminated is also heated, thus improving the bonding performance between the backing paper and the film to be laminated. The electronic thermometer 163 detects the temperature of the backing paper and the film to be laminated between the two sets of pressure rollers in real time and transmits the signal to the temperature controller 162. The temperature controller 162 adjusts the heating tube below the second lower pressure roller 13 in a timely manner according to the temperature deviation. Temperature 161 is used for temperature compensation during the second bonding process, thereby improving the yield rate. The second motor 182 operates according to the thickness measured by the thickness gauge 185. When the thickness of the finished release paper measured by the thickness gauge 185 is too thick, it will start forward, driving the worm gear 184 and worm wheel 183 through the four-output reducer 181, so that the threaded rod 172 is driven forward, driving the threaded cylinder 173 and the upper pressure roller 14 to descend together, increasing the pressure during bonding, so that the thickness of the subsequent finished release paper becomes thinner. Conversely, if the thickness of the finished release paper is too thin, the above components will start in reverse, reducing the pressure during bonding, so that the thickness of the subsequent finished release paper becomes thicker, so that the overall thickness of the finished release paper meets the design standard.

[0031] The above embodiments are only for illustrating the technical concept of this utility model and should not be used to limit the protection scope of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the protection scope of this utility model.
