Description

Technical Field

[0001] The utility model relates to the technical field of window lining paper processing, in particular to a paper leveling device of a window lining paper rewinder. Background Art

[0002] In the production process of cigarette liner paper, the rolled-up paper needs to be rewound. However, in the existing device, due to the change in the outer diameter of the paper on the roller during the rewinding process, sometimes over-unwinding occurs, and sometimes insufficient unwinding occurs, resulting in the paper being torn. In addition, sometimes the surface tension of the paper is insufficient, resulting in wrinkles or unevenness on the paper. Therefore, a paper leveling device for a cigarette liner paper rewinder is needed.

[0003] For example, the utility model with application number 202122531941.6 discloses a paper leveling device for a cigarette liner paper rewinding machine. The utility model has a simple structure and is easy to use. It can adjust the unwinding speed according to the surface tension of the paper, and can flatten the paper to reduce wrinkles on the paper. When using this device, a paper roller is placed between a first clamping head and a second clamping head, and the electric telescopic shaft is controlled to extend to clamp the paper roller between the first clamping head and the second clamping head. The paper on the paper roller is sequentially passed between two exhaust hoppers and two air bags. The paper is then passed around the first and second paper guide rollers and wound onto the rewinding roller of the rewinder. When the rewinding roller begins to rewind the paper, the second paper guide roller and the slider are pulled while the paper is being pulled, thereby causing the spring to contract and the pressure on the pressure sensor to gradually increase. The controller controls the speed of the motor based on the pressure change on the pressure sensor. As the pressure increases, the speed of the motor increases, and as the pressure decreases, the speed of the motor decreases. At the same time, during this process, the controller controls the fan to inflate the air bags. The two air bags inflate and squeeze the paper, which can flatten the paper and reduce the generation of wrinkles on the paper. Through this device, the unwinding speed of the paper roller during the rewinding process can be controlled, and tension can be applied to the paper. The squeezing of the paper by the two air bags flattens the paper, thereby improving the quality of the rewound paper.

[0004] Similar to the above application, there are still some deficiencies:

[0005] The paper leveling device of this cigarette liner paper rewinding machine does not have a limiting device. When the paper transitions to the outside of the guide roller, it may cause the paper to deviate. The paper deviation will cause the paper to be tight on one side and loose on the other side during the rewinding process, which brings inconvenience to the leveling work of the window liner paper.

[0006] Therefore, a paper leveling device for a window liner paper rewinder is designed to optimize the above problems. Utility Model Content

[0007] The main purpose of the utility model is to provide a paper leveling device for a window liner paper rewinder to solve the related technical problems raised in the above background technology.

[0008] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0009] A paper leveling device for a window lining paper rewinder comprises a processing frame, a limiting roller is installed inside the processing frame, a rotating shaft is provided inside the processing frame, an adjustment mechanism is provided between the bottom of the rotating shaft and the inside of the processing frame, an adjusting tube is rotatably installed between the rotating shafts, sliding holes are provided on both sides of the adjusting tube, a limiting ring is movably sleeved on the outer side of the adjusting tube, a bolt is installed through the outer side of the limiting ring, and one end of the bolt passes through and extends to the inside of the adjusting tube, a sleeve is threadedly installed on the outer side of the bolt, a positioning block is threadedly connected to the outer side of the bolt and located inside the adjusting tube, limiting blocks are symmetrically installed up and down inside the adjusting tube, and limiting rods are evenly arranged on the outer side of the limiting ring.

[0010] Preferably: the adjustment mechanism includes a motor and a push block, the motor is located on the inner bottom wall of the processing frame, the output shaft of the motor is fixed with a bidirectional screw, the outer side of the bidirectional screw is symmetrically threaded with a slider, and the bottom of the slider is slidingly connected to the inner bottom wall of the processing frame, the top of the slider is hinged with a push rod, the top of the push rod is hinged with a push block, and the push blocks are respectively mounted on both ends of the rotating shaft.

[0011] Preferably, movable blocks are fixed at both ends of the rotating shaft, and limiting grooves are provided inside the processing frame and at positions aligned with the movable blocks, and the limiting grooves are slidably connected to the movable blocks.

[0012] Preferably, one side of the positioning block is configured as an arc-shaped surface that matches the shape of the adjustment tube, and the outer side of the positioning block is provided with anti-slip grooves.

[0013] Preferably, a protective layer is fixed on the outer side of the movable block, and the protective layer is a wear-resistant protective layer.

[0014] Preferably, an anti-slip ring is provided on the outer side of the sleeve, and the anti-slip ring is a rubber anti-slip ring.

[0015] The beneficial effects of the utility model are:

[0016] The utility model provides a paper leveling device for a window liner rewinder. By cooperating with a processing frame, a limiting roller, a rotating shaft, an adjusting tube, a sliding hole, a bolt, a sleeve, a positioning block, a limiting block, a limiting ring and a limiting rod, the position of the limiting ring can be adjusted according to the width of the window liner and both sides thereof can be limited, thereby preventing the window liner from shifting during the winding process, thereby preventing the paper from deflecting and folding, and thus improving the practicality of the paper leveling device for a window liner rewinder.

[0017] Through the coordinated use of the motor, bidirectional screw, slider, push rod and push block, according to the tension of the paper, the motor is started to drive the bidirectional screw to rotate, and the rotation of the bidirectional screw drives the two sets of sliders to move in opposite directions, and then drives the top push rod, push block and adjustment tube to move up and down to adjust the tension of the paper. The bidirectional screw drives the push rod to push up or pull down both ends of the rotating shaft at the same time, so that both ends of the rotating shaft can move up and down at the same time, avoiding the different heights of the two ends of the rotating shaft, which causes the paper to not be completely attached to the outside of the rotating shaft, affecting the leveling work of the paper, thereby improving the accuracy of the paper leveling device of the window liner paper rewinder;

[0018] By using the movable block and the limit slot in conjunction with each other, the movable block is driven to move simultaneously as the rotating shaft moves up and down, and the movable block moves up and down along the limit slot inside the limit slot, making the up and down movement of the rotating shaft more precise and stable, and making the window lining paper fit more closely with the rotating shaft, thereby meeting people's usage needs.
