Description

Technical Field

[0001] This utility model relates to the field of adhesive paper production equipment technology, and in particular to an adhesive amount adjustment structure for an impregnation production line used in adhesive paper production. Background Technology

[0002] Adhesive film paper is produced by impregnating base paper with adhesive, coating, and cutting on an impregnation production line. During the impregnation process, adjusting the amount of adhesive applied is crucial to meet the requirements of different products and customers. Deviations in the amount of adhesive applied not only waste adhesive but also severely affect product quality: too little adhesive leads to wrinkles, cracks, and edge curling, and the film may show through; too much adhesive results in wasted adhesive, a damp film that folds and sticks to the rollers, increasing the risk of paper breakage. Early adhesive application control, limited by technology and equipment, relied on manual adjustment of the adhesive amount at the beginning and middle of the production line, followed by product testing at the end. This repetitive process was time-consuming, made it difficult to guarantee product quality, and resulted in slow overall efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a structure for adjusting the amount of adhesive applied to the film paper, which electrically adjusts the amount of adhesive applied, thus effectively solving the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The adhesive coating amount adjustment structure for film paper impregnation includes a frame and a first and second adhesive rollers assembled on the frame and equipped with rolling adhesive application. The two ends of the first adhesive roller are connected to the frame via bearings, allowing it to straddle the frame and rotate. The two ends of the second adhesive roller are connected to two parallel sliding seats via bearings, allowing it to rotate. The two sliding seats are mounted on the frame via linear guides, allowing the second adhesive roller to straddle the frame and be parallel to the first adhesive roller. The adhesive coating amount is adjusted by the second adhesive roller moving closer to or further away from the first adhesive roller as it follows the sliding seats. The structure also includes an electric adjustment system. This system uses a telescopic screw to coordinate the support of the sliding seats. An Omron distance sensor is incorporated into the electric adjustment system. The signal from the Omron distance sensor is connected to the PLC controller of the impregnation production line. The PLC controller controls the electric adjustment system to drive the sliding seats to move, and displays the values ​​on the displays at each station.

[0006] The above scheme is further described in that the front ends of the two sliding seats are supported by two first lead screws, and the rear ends of the two sliding seats are supported by two second lead screws. The first lead screws and the second lead screws are respectively connected to the screw holes preset on the frame, so as to realize the rotation and extension of the first lead screws and the second lead screws to drive the sliding seats to move, and the two sliding seats are adjusted and moved synchronously.

[0007] The above solution is further described in that the first and second gluing rollers are installed on the same horizontal plane, and the materials and outer diameters of the first and second gluing rollers are the same.

[0008] The above scheme is further described as follows: the two first lead screws are driven by the same first servo motor. The output end of the first servo motor transmits power to the active diverter rod through a gear assembly. The active diverter rod is vertically arranged, and its upper end is connected to one of the first lead screws through a first gearbox. The lower end of the active diverter rod is connected to one end of a horizontally arranged driven diverter rod through a second gearbox. The other end of the driven diverter rod extends and is connected to a vertically arranged end drive rod through a third gearbox. The upper end of the end drive rod is connected to the other first lead screw through a fourth gearbox. The two second lead screws are directly connected to the output ends of two second servo motors, and the two second servo motors work synchronously. Omron ranging sensors are embedded in the output ends of the first and second servo motors, respectively.

[0009] This invention designs a first and second coating roller for rolling adhesive application. The first coating roller is connected to the frame at both ends via bearings, while the second coating roller is connected to two parallel sliding seats at both ends via bearings. The second coating roller moves with the sliding seats to move closer to or further away from the first coating roller, thus adjusting the amount of adhesive applied. The movement of the sliding seats is driven by an electric adjustment system. This system uses a telescopic screw to coordinate the support of the sliding seats and incorporates an Omron distance sensor. The signal from the Omron distance sensor is input to the PLC controller of the impregnation production line. The PLC controller controls the electric adjustment system to drive the sliding seats and displays the values ​​on the screens at each station. The design is simple, has low investment costs, and is easy to operate. After receiving the signal, the PLC controller sends a control signal, allowing the operator to monitor the changes in the screen values ​​in real time. For example, if the amount of adhesive applied is 1g less, the displayed value should be increased by 10; conversely, if the amount of adhesive applied is 1g more, the displayed value should be decreased by 10. From the moment the first finished sheet is cut and the difference in glue application is detected, the glue application value is immediately observed on the touchscreen and remotely adjusted. The electric adjustment can complete the glue application adjustment in as little as 10 seconds, thus ensuring product quality and reducing waste of glue and adhesive film. It can quickly control the glue application requirements for different paper weights and different production processes, achieving production flexibility; it ensures uniform glue application, clear texture, and wrinkle-free paper, improving product quality; and it makes production smoother, reducing unnecessary waste caused by untimely glue application adjustments.

[0013] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model.

These terms are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] See Figure 1 , 2 Figure 3 shows a schematic diagram of a preferred embodiment of the present invention. The present invention relates to a structure for adjusting the amount of adhesive applied to a film paper after impregnation. It includes a frame 1 and a first adhesive roller 2 and a second adhesive roller 3 assembled on the frame and used for rolling adhesive application. During operation, after impregnation, the base paper passes between the first adhesive roller 2 and the second adhesive roller 3. The first adhesive roller 2 and the second adhesive roller 3 respectively roll and contact the two sides of the base paper, and squeeze and scrape the adhesive on the corresponding sides of the base paper, so that the corresponding adhesive is retained on the base paper and evenly coated. In this embodiment, the two ends of the first gluing roller 2 are respectively connected to the frame through bearings, so that the first gluing roller 2 is mounted across the frame and can rotate. The two ends of the second gluing roller 3 are respectively connected to two parallel sliding seats 4 through bearings, so that the second gluing roller 3 can rotate. The two sliding seats 4 are respectively mounted on the frame through linear guide rails, so that the second gluing roller 3 is mounted across the frame and is parallel to the first gluing roller 2. By moving the second gluing roller 3 along with the sliding seats 4 to move closer to or further away from the first gluing roller 2, the amount of glue applied can be adjusted. The system also includes an electrically operated adjustment system. This system uses a telescopic lead screw to coordinate the movement of the sliding seat 4. An Omron distance sensor 51 is incorporated into the system, and its signal is connected to the PLC controller of the impregnation line. The PLC controller controls the electrically operated adjustment system to move the sliding seat 4, thereby adjusting the amount of adhesive applied to the film paper by adjusting the distance between the first and second glue rollers 2 and 3. This electrically operated adjustment overcomes the shortcomings of manual adjustment, completing the adjustment in as little as 10 seconds, thus ensuring product quality and reducing waste of glue and film paper. The PLC controller for the impregnation line is existing technology, and its working principle will not be elaborated here. The PLC controller can also display values ​​on the screens at each station, allowing operators to monitor the changes in the screen values ​​in real time. For example, if the amount of adhesive applied is 1g less, the displayed value should be increased by 10; conversely, if the amount of adhesive applied is 1g more, the displayed value should be decreased by 10, facilitating control.

[0016] Figure 1 , 2As shown in Figures 1 and 3, in this embodiment, the first gluing roller 2 and the second gluing roller 3 are installed on the same horizontal plane and located above the pre-set glue tank of the frame 1, so that after the paper is impregnated with glue, it passes from top to top between the first gluing roller 2 and the second gluing roller 3, and is output from the upper side of the first gluing roller 2 after passing through. In this embodiment, the material and outer diameter of the first gluing roller 2 and the second gluing roller 3 are the same to ensure that the glue is applied evenly on both sides of the film paper. The rotation of the first gluing roller 2 and the second gluing roller 3 can be driven by the passage of the paper, or it can be driven by a power source; there is no limitation on this.

[0017] Figure 3 As shown, this invention is integrated into an impregnation production line, located between the unwinding machine 100 and the baking oven 200. The base paper is unwound from the unwinding machine 100 and fed into a pre-set glue tank on the frame 1. After impregnation, the base paper passes between the first glue roller 2 and the second glue roller 3. The first glue roller 2 and the second glue roller 3 respectively roll and contact both sides of the base paper, squeezing and scraping the glue on the corresponding sides of the base paper to ensure that the corresponding glue is retained on the base paper and evenly coated. The glued paper with the adjusted glue amount enters the baking oven 200 for heating and shaping to produce the required glued paper.

[0018] Figure 1 , 2As shown in Figure 3, in this embodiment, the front ends of the two sliding seats 4 are supported by two first lead screws 52, and the rear ends of the two sliding seats 4 are supported by two second lead screws 53. The first lead screws 52 and the second lead screws 53 are threadedly connected to the pre-set screw holes on the frame, so as to realize the rotation and extension of the first lead screws 52 and the second lead screws 53 to drive the sliding seats 4 to move, and the two sliding seats 4 adjust and move synchronously. Further, the two first lead screws 52 are driven by the same first servo motor 55, which optimizes the structure and improves synchronous operation. The output end of the first servo motor 55 transmits power to the active diverter transmission rod 54 through a gear assembly. The active diverter transmission rod 54 is set vertically, and the first servo motor 55 is arranged in a direction perpendicular to the active diverter transmission rod 54. The gear assembly is a turbine structure. The upper end of the active diversion drive rod 54 is connected to one of the first lead screws 52 via a first gearbox 561; the lower end of the active diversion drive rod 54 is connected to one end of a horizontally arranged driven diversion drive rod 57 via a second gearbox 562, and the other end of the driven diversion drive rod 57 extends and is connected to a vertically arranged end drive rod 58 via a third gearbox 563. The upper end of the end drive rod 58 is connected to another first lead screw 52 via a fourth gearbox 564. The two second lead screws 53 are directly connected to the output ends of two second servo motors 59, and the two second servo motors 59 operate synchronously via electronic control; Omron distance sensors 51 are embedded in the output ends of the first servo motor 55 and the second servo motor 59, respectively. During adjustment, the first lead screw 52 and the second lead screw 53 work together to move forward and backward, thereby moving the sliding seat 4 closer to or further away from the first glue roller 2. The second glue roller 3 follows the movement of the sliding seat 4 to move closer to or further away from the first glue roller 2. By adjusting the distance between the first glue roller 2 and the second glue roller 3, the amount of glue applied can be adjusted.
