Abstract
Description
Technical Field

[0002] In the production of dipped paper, the base paper goes through the steps of dipping, coating, and cutting, and deviation adjustment is an essential step. Instability in deviation adjustment not only affects product quality but also disrupts stacking, and can even lead to serious consequences such as paper breakage and waste. For example, slow deviation adjustment can affect the paper feed, preventing the uniform removal of excess glue from the edges, leading to sticking, wrinkling, breakage, and uneven stacking. Fast deviation adjustment can lead to excessive tension, vibration, and even breakage, resulting in unnecessary losses. Early deviation adjustment systems for dipped paper production used pneumatic detection nozzles, which controlled the airflow within the jet tube through a motor-driven diaphragm, thereby driving the valve group to perform hydraulic cylinder adjustment. Due to their slow speed and the heat-prone motor, manual intervention was often required, making them unsuitable for products of varying weights. Summary of the Invention

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0016] See Figure 1 、 2 Figures 3 and 3 are schematic structural diagrams of a preferred embodiment of the present invention. The present invention relates to an adjustment device for the production of impregnated paper, which includes a frame 1 and an adjustment control unit. The adjustment control unit is integrated into the control system of the impregnated paper production line. A support frame 2 is mounted on the frame 1, and the support frame 2 can be rotated and adjusted on a horizontal plane around a support point 4. The support frame 2 is provided with a force-applying portion 21. A servo electric cylinder 5 is provided between the force-applying portion 21 and the frame 1. The servo electric cylinder 5 is used to drive the support frame 2 to rotate around the support point 4 and provide support. The support of the servo electric cylinder 5 can enable the support frame 2 to present a stable posture at a certain spatial position to meet production needs. The servo electric cylinder 5 is electrically connected to the adjustment control unit and is controlled by the adjustment control unit. A feed roller group 6 is installed on the support frame 2. The feed roller group 6 is arranged horizontally in the conveying direction of the impregnated paper 7, so that the impregnated paper 7 can pass through the feed roller group 6 and be correspondingly tightened to ensure smooth transmission.
[0017] Figure 1 、 2As shown, in this embodiment, the support frame 2 is designed as a square frame and is installed flat on the upper end of the frame 1. The support point 4 is the hinged connection point between one corner of the support frame 2 and the frame 1. It uses a shaft hole hinge connection and is equipped with corresponding flat bearings to improve rotational stability and accuracy. The frame 1 is equipped with support rollers 11 at the other three corners of the support frame 2. The support rollers 11 are used to support the lower side of the support frame 2. The multi-point support makes the support frame 2 stable and easy to adjust. The force-applying portion 21 is located at one of the corner ends of the support frame 2. The force-applying portion 21 and the support point 4 are offset and distributed together on the same side of the conveying direction of the impregnated paper 7. The servo electric cylinder 5 is positioned within a hollowed-out area at the lower portion of the support frame 2, angled to one side of the support point 4. The force-applying portion 21 of the support frame 2 protrudes slightly downward, allowing the telescopic end of the servo electric cylinder 5 to be hingedly connected to the force-applying portion 21, thereby enabling the support frame 2 to be pushed and pulled. The telescopic movement of the servo electric cylinder 5 pushes and pulls the support frame 2, allowing the support frame 2 to be adjusted horizontally about the support point 4. This compact and rational structure ensures smooth and reliable push and pull operations of the servo electric cylinder 5 without affecting the rotation of the support frame 2.
[0018] Figure 1 、 2 As shown, in this embodiment, a sensing bracket 3 is further provided on the frame 1, and an ultrasonic sensor 31 is provided on the sensing bracket 3. The ultrasonic sensor 31 is used to detect the conveying position of the impregnated paper and feed it back to the deviation adjustment control unit. The deviation adjustment control unit sends a control signal to the servo electric cylinder 5 based on the position deviation feedback received from the ultrasonic sensor 31. The servo electric cylinder 5 drives the support frame 2 to rotate and adjust around the support point 4, so that the feed roller group 6 pulls the impregnated paper 7 for deviation adjustment, so that the conveying position of the impregnated paper 7 is restored to the reference point of the ultrasonic sensor 31. Furthermore, the sensing bracket 3 is a door-shaped structure, and the impregnated paper 7 passes through the sensing bracket 3. The sensing bracket 3 has two ultrasonic sensors 31. The two ultrasonic sensors 31 are respectively arranged on the left and right sides of the conveying direction of the impregnated paper 7 and are symmetrical. This realizes simultaneous detection of both sides of the impregnated paper 7, prevents the impregnated paper from excessive deviation during unilateral detection, and reduces accidents. In this embodiment, the ultrasonic sensor feeds back a position deviation signal. After receiving the signal, the deviation adjustment control unit sends a control signal to the servo motor on the servo electric cylinder 5 to adjust the deviation according to the set proportional value, the encoder on the servo motor and other conditions, so that the position of the impregnated paper 7 is restored to the reference point of the ultrasonic sensor.
[0019] In this embodiment, the feeding roller group 6 includes a first tensioning conveying roller 61 and a second tensioning conveying roller 62, and the first tensioning conveying roller 61 and the second tensioning conveying roller 62 are respectively distributed on the upper and lower sides of the impregnated paper 7 and are staggered front and back, so that the impregnated paper 7 is tensioned on the first tensioning conveying roller 61 and the second tensioning conveying roller 62, which is convenient for output, and can timely and accurately grasp the impregnated paper 7 for adjustment when adjusting the deviation, thereby improving the adjustment speed and accuracy.
[0020] Figure 3 As shown, when the present invention is used, the frame 1 is installed between the working unit 100 and the traction machine 200, and the position of the feed roller group 6 is adjusted by means of a pad on the frame 1, etc., to ensure that the impregnated paper 7 is tensioned and conveyed. If the film paper deviates, two ultrasonic sensors 31 synchronously detect the position of the impregnated paper 7. After receiving the signal, the deviation control unit sends a control signal to the servo motor on the servo electric cylinder 5 according to the set ratio value, the encoder on the servo motor, and other conditions to adjust the deviation. The support frame 2 can rotate forward and backward around the support point 4 on the horizontal plane. The feed roller group 6 follows the twisting and drives the impregnated paper 7 to move to the left and right of the conveying direction, so that the position of the impregnated paper 7 is restored to the reference point of the ultrasonic sensor, achieving automatic deviation control, facilitating production and improving production quality.
[0021] The utility model can achieve stable control for materials with different properties, different production processes, and different set production speeds, making production more flexible and reliable; it automatically adjusts the deviation of the film paper after it deviates, ensuring the film paper's centering operation, reducing the time-consuming and labor-intensive problem of manual pulling and traction, and saving manpower; the produced film paper has a smooth surface, no wrinkles, accurate cutting size, and neat stacking, greatly improving product quality; it makes production smoother, and reduces unnecessary waste caused by paper breakage and production stoppage due to unstable deviation adjustment.

Its purpose is to enable people familiar with this technology to understand the content of the present invention and implement it.
