Description

Technical Field

[0001] The utility model relates to the technical field related to laminated paper, in particular to a laminated paper rack with a deviation correction mechanism. Background Art

[0002] Laminated paper is a composite material made by coating a thin layer of plastic film (such as PE film) on the surface of ordinary paper. It has excellent properties such as waterproof, oil-proof and moisture-proof. Laminated paper is widely used in food packaging, medical packaging, building materials and industrial packaging. Its production process includes paper surface treatment, coating, laminating, drying and other steps to ensure that it has good physical properties and stable chemical properties. The advantage of laminated paper lies in its excellent protective performance and low production cost. Compared with traditional waterproof paper, laminated paper can not only effectively block the penetration of water and grease, but also has high tear resistance and tensile strength. In addition, laminated paper can be processed secondary as needed, such as printing, laminating, cutting, etc., to meet the personalized needs of different customers. During use, in the production process of laminated paper, paper rolls are often affected by problems such as paper offset and curling, affecting production quality and efficiency.

Therefore, a laminated paper rack with a correction mechanism is particularly needed.

During the production process of laminated paper, if the paper roll deviates, the laminated layer will cover the paper unevenly, resulting in a decrease in the quality of the finished product. The deviation problem that occurs during the production process requires manual adjustment or reprocessing, which not only increases the scrap rate, but also wastes raw materials and production time, significantly increasing production costs.

[0025] Furthermore, the supporting mechanism 2 includes a shock-absorbing pad 201, a mounting frame 202, a supporting frame 203, a side baffle 204 and a roller 205.

The side baffles 204 and the roller 205 are set up. During use, the shock-absorbing pads 201 are made of rubber to increase friction and reduce the impact of vibration on production. The support frame of the overall structure of the mounting frame 202 is welded from steel to provide stable support. The support frame 203 forms a triangle on both sides of the mounting frame 202 with higher stability and plays a supporting role. The side baffles 204 are fixed on both sides of the mounting frame 202 to prevent the paper roll from falling off.

The threads at both ends of the forward and reverse threaded screw 304 are rotated in opposite directions and are respectively threadedly connected to the limit block 305. Since the movement direction of the limit block 305 is opposite when the thread rotates in opposite directions, it will move inward or outward at the same time, so that the paper roll on the roller 205 is clamped by the limit block 305, and the centering is ensured to prevent deviation.

The base 401, the limiting rod 402, the compression spring 403, the movable column 404 and the lifting claw 405 are arranged. During use, the compression spring 403 is installed inside the mounting base 401 through the limiting rod 402, the movable column 404 can slide in the mounting base 401 but will be lifted up by the compression spring 403, and the lifting claw 405 is lifted up to make it contact with the wound paper roll, playing a supporting role, preventing the paper roll from being concentrated in the middle of the roller 205 and pressing down the middle for a long time, causing the roller 205 to bend.

[0034] Working principle: A laminated paper stand with a deflection correction mechanism. When the laminated paper roll rotates on the roller 205, the deflection correction sensor 301 monitors the edge position of the paper roll in real time. If it is detected that the paper roll deviates from the predetermined position, the sensor sends a signal to the controller 303. The controller 303 calculates the offset according to the sensor signal and drives the deflection correction motor 302. The deflection correction motor 302 drives the paper roll to slide along the roller 205 through the sliding component 306, so that the paper roll returns to the correct position. The side baffle 204 and the limit block 305 ensure that the sliding component 306 operates within a safe range to prevent equipment damage. The lifting mechanism 4 lifts the lifting claw 405 to make it contact with the rolled paper roll, which plays a supporting role to prevent the paper roll from being concentrated in the middle of the roller 205 and pressing down on the middle for a long time to cause the roller 205 to bend. In this way, a laminated paper stand with a deflection correction mechanism is completed.
