Description

Technical Field

[0001] This utility model relates to the field of winding and unwinding technology, and in particular to an automated winding and unwinding device for multi-layer composite release paper. Background Technology

[0002] With the rapid development of modern industry, multilayer composite release paper is increasingly widely used in many fields such as tapes, labels, electronic materials, and optical films. Taking the tape industry as an example, high-performance double-sided tapes require multilayer release paper to provide stable support and protection; in the field of electronic materials, the composite quality of lithium battery separator release paper and flexible circuit board (FPC) release paper directly affects the performance and reliability of electronic products.

[0003] Traditional equipment typically cannot precisely control the tension of each layer of release paper after unwinding. The lack of effective tension control components causes significant fluctuations in release paper tension during unwinding due to factors such as changes in the release paper roll diameter and variations in equipment operating speed. This can lead to problems such as stretching deformation, wrinkling, and even breakage of the release paper, severely impacting the quality of subsequent lamination processes and ultimately affecting the quality of the final product. Furthermore, the laminated release paper rolls after winding are often quite heavy. Existing equipment lacks a reasonable auxiliary roll-removal design, requiring workers to expend considerable physical effort manually handling and removing the rolls. This is not only inefficient but also carries the risk of damage to the rolls or worker injury due to improper handling. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the tension of each layer of release paper cannot be accurately controlled after unwinding, and to propose an automated unwinding and rewinding device for multi-layer composite release paper.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an automated unwinding and rewinding device for multi-layer composite release paper, comprising a hot press, a first support plate fixedly connected to one end of the hot press and near both sides, a groove being formed on one side wall of each of the first support plates, a second support plate and a third support plate fixedly connected to the other end of the hot press and near both sides respectively, an unwinding rod being rotatably connected to the surface of the second support plate through a bearing, a release paper roll being sleeved on the surface of the unwinding rod, a screw groove being formed at one end of each unwinding rod, a compression cylinder being sleeved at one end of each compression cylinder, a second screw being slidably connected to one end of each compression cylinder through a screw, one end of the second screw being embedded in the screw groove and threadedly connected thereto, and a rotating component being fixedly connected to one end of each second screw; a lifting assembly installed inside the groove; and a tension control assembly bearing mounted on the surface of the unwinding rod.

[0006] Preferably, the lifting assembly includes two first screws, each of which is located inside the groove and rotatably connected to a bearing on its bottom inner wall. The top of each first screw penetrates the top inner wall of the groove and is rotatably connected to a bearing thereon. Lifting components are threaded onto the surfaces of each first screw, and a first support component and a second support component are fixedly connected to the surfaces of the lifting components, respectively.

[0007] Preferably, a first motor is fixedly connected to one side wall of the second support member, a second motor is fixedly connected to the top of each of the first support plates, the output ends of the second motors are fixedly connected to the top of the first screw, and three third motors are fixedly connected to one side wall of the second support plate, the output ends of the third motors are fixedly connected to one end of the unwinding rod.

[0008] Preferably, the tension control assembly includes three limiting discs, each of which is sleeved on the surface of the unwinding rod and rotatably connected to its bearing. A gear disc is sleeved on the surface of the unwinding rod and rotatably connected to a bearing on one side of the limiting disc, and the gear disc is fixedly connected to the limiting disc. A fourth motor is embedded and fixedly connected to the surface of the second support plate and above the unwinding rod. A gear is fixedly connected to the output end of each fourth motor, and the gear meshes with the gear disc. A fixing plate is fixedly connected to the surface of each limiting disc, and a protrusion is provided at the other end of each fixing plate. A push rod is fixedly connected to the surface of each protrusion.

[0009] Preferably, one end of each of the fixing plates is embedded and fixedly connected with an electric push rod, and the output end of each electric push rod is fixedly connected to a protrusion.

[0010] Preferably, a control panel is fixedly mounted on the surface of the second support plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, a fourth motor drives a gear to rotate, which in turn drives a gear disc to rotate, which in turn drives a limiting disc to rotate, which in turn drives a fixing plate to rotate. At this time, the fixing plate can drive a push rod to press the release paper downward, which can adjust the force of each layer of release paper during the conveying process. At the same time, an electric push rod drives a protrusion to move, which in turn drives a push rod to move, which can adjust the tension position of the push rod. This ensures that the release paper is always in a suitable tension state during the unwinding process, reducing deformation, wrinkles and other problems, and improving the quality of the composite process and the product quality.

[0013] 2. In this utility model, the winding rod is placed on the first support and the second support for winding. After the winding is completed, the first screw is driven to rotate by the second motor. The rotation of the first screw can drive the lifting member to descend. The descent of the lifting member can drive the support member to descend, which can make the bottom of the wound multi-layer composite release paper contact the ground. This can achieve the effect of making the two ends of the winding rod separate from the inside of the support member, and then the wound multi-layer composite release paper can be automatically removed.

[0026] Working principle: The release paper roll 10 is placed on the unwinding rod 7, and then the extrusion cylinder 12 is placed on one end of the unwinding rod 7. The second screw 13 passes through the extrusion cylinder 12 and rotates to embed into the screw groove 11, which can compress and fix the release paper roll 10. Then, the winding rod is placed in the first support member 43 and the second support member 44. At this time, one end of the release paper roll 10 can pass through the push rod 97 above or below and pass through the hot press 1 for hot pressing. After hot pressing, the multi-layer composite release paper can be wound up by the first motor 45 driving the winding rod 7 to rotate. During this process, the unwinding rod can be driven by the third motor 8, and the gear 94 can be driven by the fourth motor 93. The rotation of gear 94 drives the rotation of gear disc 92, which in turn drives the rotation of limit disc 91, which in turn drives the rotation of fixing plate 95. At this time, fixing plate 95 can drive push rod 97 to squeeze release paper downward or upward, which can adjust the force of each layer of release paper. After winding is completed, the first screw 41 can be driven to rotate by the second motor 46. The rotation of the first screw 41 can drive the lifting component 42 to descend, which can drive the support component to descend. This can make the bottom of the wound multi-layer composite release paper contact the ground, thereby making the two ends of the winding rod separate from the inside of the support component, and then automatically remove the wound multi-layer composite release paper.
