Description

Technical Field

[0001] This utility model relates to the field of inner lining paper technology, specifically to a protective lining paper unwinding device. Background Technology

[0002] With increasing demand in the copper and high-precision copper processing sheet and strip market, more and more high-precision rolled strips and foils are being widely used in key industries such as cables, power, and new energy. During the production of strips and foils, quality defects such as scratches often occur due to relative displacement of the strip. This is typically addressed by adding liner paper for protection. Common liner paper methods use simple supports, but these often result in ineffective centering, misalignment, and edge damage, severely hindering product quality improvement. Furthermore, the handling and lifting of the liner paper are done manually, which is labor-intensive and poses certain safety risks. Therefore, it is necessary to unwind the liner paper during strip winding to effectively protect the layers of the strip. Currently, the existing method uses simple supports, which have many problems. Utility Model Content

[0003] The purpose of this utility model is to provide a protective liner unwinding device, which aims to solve the problems of inconvenient installation of liner rolls and easy deviation and damage during unwinding in the above-mentioned background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a protective liner unwinding device, comprising a base, a lifting platform and an auxiliary unwinding mechanism mounted on the base, wherein the lifting platform is fixedly installed at the center of the top of the base, and the auxiliary unwinding mechanism comprises two slide rails, sliding seats, mounting plates and a material support rod, wherein the two slide rails are arranged parallel to each other on the front and rear sides of the lifting platform and each slide rail has two sliding seats slidably mounted thereon, wherein the upper side of the sliding seats at the same end of the two slide rails is bolted to the same mounting plate, the two mounting plates are symmetrically distributed, and each of the two slide rails is provided with a driving mechanism for moving the mounting plates, and the two mounting plates are provided with corresponding through holes, wherein the material support rod is slidably inserted through and rotatably connected in the two through holes.

[0005] Furthermore, on one side of the two mounting plates opposite each other, multiple strip grooves are arranged outwards from the through hole, and a protective roller is rotatably installed inside the strip groove.

[0006] Furthermore, the drive mechanism includes a bidirectional screw and a stepper motor. The bidirectional screw is rotatably mounted in a groove opened on the top of the slide rail via bearings. The stepper motor is fixedly mounted on the slide rail and its output end passes through the slide rail and is fixedly connected to one end of the bidirectional screw. Two sliding seats are symmetrically distributed and are threadedly connected to two opposite threaded sections of the bidirectional screw, and the two sliding seats slide in cooperation with the groove.

[0007] Furthermore, the lifting platform is a scissor lift platform, which includes a connected scissor mechanism, a support platform, and a hydraulic system.

[0008] Furthermore, the base includes a base plate and support seats located at the left and right ends of the base plate.

[0011] This utility model provides a protective unwinding device for liner paper. Multiple rubber-coated protective rollers installed on the opposite side walls of two mounting plates in the auxiliary unwinding mechanism protect both sides of the liner paper roll during the unwinding process, preventing damage to the edges.

[0017] like Figures 1 to 4As shown, the system includes a base 1, a lifting platform 3 mounted on the base 1, and an auxiliary unwinding mechanism. The lifting platform 3 is fixedly installed at the top center of the base 1. The auxiliary unwinding mechanism includes two slide rails 2, sliding seats 4, mounting plates 5, and a material support rod 6. The two slide rails 2 are arranged parallel to each other on the front and rear sides of the lifting platform 3, and two sliding seats 4 are slidably mounted on each slide rail 2. The upper side of the sliding seats 4 at the same end of the two slide rails 2 is bolted to the same mounting plate 5. The two mounting plates 5 are symmetrically distributed. Both slide rails 2 are provided with a drive mechanism for moving the mounting plates 5. Corresponding through holes are opened on the two mounting plates 5. The material support rod 6 slides through and is rotatably connected in the two through holes. The material support rod 6 can be pulled out from the through holes by pulling.

[0018] The drive mechanism includes a bidirectional screw 7 and a stepper motor 8. The bidirectional screw 7 is rotatably mounted in a groove opened on the top of the slide rail 2 via a bearing. The stepper motor 8 is fixedly mounted on the slide rail 2 and its output end passes through the slide rail 2 and is fixedly connected to one end of the bidirectional screw 7. Two sliding seats 4 are symmetrically distributed and are threadedly connected to two opposite threaded sections of the bidirectional screw 7, and the two sliding seats 4 slide in cooperation with the groove.

[0019] On one side of the two mounting plates 5 facing each other, multiple strip grooves are arranged outward from the through hole. Inside the strip grooves, a protective roller 9 is rotatably installed. The protective roller 9 is coated with rubber and embedded in the mounting plate 5 at both ends to protect the edge of the paper and prevent damage to the edge during paper feeding. The mounting plates 5 on both sides adopt a fan-shaped design, which can reduce the weight of the overall device and facilitate movement and adjustment.

[0020] The lifting platform 3 is a scissor lift platform, which includes a connected scissor mechanism, a support platform, and a hydraulic system. The hydraulic system includes a motor, an oil tank, and a hydraulic cylinder. The motor controls the hydraulic oil in the oil tank to be introduced into or drawn out of the hydraulic cylinder through the oil supply pipe, which is used to adjust the scissor mechanism to rise or fall. The surface of the support platform has grooves formed to stabilize the paper roll.

[0021] The base 1 includes a base plate 101 and support seats 102 located at the left and right ends of the base plate 101. The support seats 102 are made of 4080LZ type aluminum profile.

[0022] It also includes a control module, which is electrically connected to the hydraulic system and two motors.

[0023] The specific operation process of this utility model is as follows:

[0024] When the lifting platform 3 is in its initial state, its height is the same as the support seats 102 at both ends of the base 1. At this time, the mounting plates 5 at both ends of the slide rail 2 are at their maximum open limit. First, the paper roll to be unwound is placed on the support platform of the lifting platform 3. Then, the motor is started through the control module, which controls the lifting platform 3 to rise and fall, so that the center of the paper roll is at the same height as the through holes on the mounting plates 5 on both sides. Then, the material support rod 6 is passed through the through holes and into the roll inside the paper roll, so that the paper roll is fixed on the material support rod 6. Then, the lifting platform 3 is controlled to descend and be placed in a flat position. Then, by controlling the two stepper motors 8 to rotate, the sliding seats 4 on both sides of the bidirectional screw 7 drive the mounting plates 5 to move synchronously in opposite directions, so that the embedded guard rollers 9 on the mounting plates 5 on both sides are close to the side of the paper roll. At this time, the unwinding operation begins. After the copper strip roll of paper roll reaches a certain length or the paper roll is used up, the mounting plates 5 on both sides are opened to the maximum limit for material waiting operation.
