Description

Technical Field

[0001] This utility model belongs to the field of winding machine technology, specifically, it relates to a high-efficiency strip winding and centering device. Background Technology

[0002] Winding machines are key winding equipment in continuous production lines such as steel rolling, papermaking, film production, and textiles. Their core function is to wind continuously produced strip materials (such as metal strips, paper, and non-woven fabrics) into dense rolls at high speed and neatly under constant tension control. They typically consist of a drive mechanism, a drum, pressure rollers, a tension control system, and auxiliary guiding devices. By precisely controlling the winding tension and strip alignment, they effectively prevent defects such as loose winding, collapse, tapering, or surface scratches, ensuring uniform internal stress within the roll. This provides a solid foundation for the safe transportation, storage, and subsequent efficient processing of materials, making it a core element in ensuring product quality and production efficiency.

[0003] Currently, before winding strip materials, horizontal winding machines require aligning the take-up drum concentrically with the rotating shaft of the winding machine and inserting it onto the rotating shaft before winding the strip materials. Specifically, the take-up drum is placed on the two support rollers A on the upper surface of the fixed base, using the support rollers A to support the take-up drum. Then, the movable fixed base is used to fit the take-up drum onto the rotating shaft. After the rotating shaft internally supports and fixes the take-up drum, the winding action of the strip materials can be performed.

[0004] However, in practical applications, such as Figure 6 and Figure 7 As shown, the winding roller A, which has been wound up, needs to be removed from the rotating shaft using the fixed base and the support rollers A symmetrically arranged on the upper surface of the fixed base to facilitate the subsequent strip winding process. However, due to the inability to adjust the spacing between the support rollers A and the increasing diameter caused by the increasing amount of strip material wound on the winding roller A, the center of gravity of the winding roller A after the strip material is wound is unstable when placed on the support rollers A, which poses a safety hazard and has certain limitations. Utility Model Content

[0005] The purpose of this utility model is to provide an efficient strip winding and centering device to solve the technical problem in the prior art that the center of gravity of the winding roller A after the strip is wound on the support roller A is unstable and poses a safety hazard because the spacing between the support rollers A cannot be adjusted and the diameter of the winding roller A gradually increases due to the increase in the amount of strip wound on the winding roller A.

[0006] The objective of this utility model can be achieved through the following technical solutions: A high-efficiency strip and sheet winding and centering device includes a fixed base; a winding machine is fixedly connected to the fixed base; a slide rail is fixedly connected to the fixed base in the direction corresponding to the output end of the winding machine; a movable middle plate is slidably connected to the slide rail; a movable upper plate and a movable lower plate are respectively provided above and below the movable middle plate; symmetrically arranged guide rods are fixedly connected to the upper surface of the movable upper plate via a fixed block; an inverted trapezoidal connecting plate is provided on each side of the fixed block, and the connecting plate is slidably connected to the corresponding guide rod; a support base is fixedly connected to the upper part of each connecting plate; multiple evenly distributed hinge seats are fixedly connected to the support bases; and a support roller B is rotatably connected to each hinge seat.

[0007] Furthermore, the four corners of the movable upper plate and the movable lower plate are connected by connecting rods, and the connecting rods are slidably connected to the movable middle plate.

[0008] Furthermore, two SC telescopic cylinders with upward-facing output ends are fixedly connected to the lower surface of the movable lower plate, and their output ends pass through the movable lower plate and are connected to the movable middle plate.

[0009] Furthermore, a bidirectional lead screw is fixedly installed in the middle of the upper surface of the movable upper plate via a bearing seat, and the two ends of the bidirectional lead screw are respectively threaded to two connecting plates.

[0010] Furthermore, a servo motor is fixedly installed on the lower surface of the movable upper plate; the output end of the servo motor is driven to the bidirectional lead screw through the cooperation of a sprocket and a chain.

[0011] Furthermore, the moving middle plate has a through slot corresponding to the position of the servo motor.

[0012] The beneficial effects of this utility model are: 1. When the two connecting plates move closer or further away from each other on the guide rod, the two symmetrical support rollers B will move closer or further away simultaneously. If the support rollers B move closer to each other, the requirements for installing the take-up roller B on the winding machine can be met. If the support rollers B move further away from each other, the requirements for unloading the take-up roller B with the strip material can be met. This will not cause the center of gravity to be unstable when the support roller B is mounted on the take-up roller B, thus avoiding personal safety and economic losses.

[0013] 2. When the servo motor of this utility model drives the bidirectional lead screw to rotate in both directions through the sprocket and chain, the bidirectional lead screw can drive the connecting plate to move closer or further away synchronously, thereby achieving the purpose of adjusting the distance between the support rollers B, and thus achieving the function of stabilizing the winding rollers B before or after the winding of the strip. The structure is simple and easy to use.

[0014] 3. When the output end of the SC telescopic cylinder extends or retracts, the lower moving plate and the upper moving plate move synchronously to descend or rise because the middle moving plate is connected to the slide rail. This allows the take-up roller B to be smoothly mounted on the rotating shaft of the winding machine, making centering efficient and convenient. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 - Figure 5As shown, a high-efficiency strip and sheet winding and centering device includes a fixed base 1 placed on the ground; a winding machine 2 is fixedly connected to the fixed base 1; a slide rail 3 is fixedly connected to the fixed base 1 corresponding to the output end of the winding machine 2; a movable middle plate 5 is slidably connected to the slide rail 3; a movable upper plate 6 and a movable lower plate 7 are respectively provided above and below the movable middle plate 5; the four corners of the movable upper plate 6 and the movable lower plate 7 are connected by connecting rods 8, and the connecting rods 8 are slidably connected to the movable middle plate 5; two SC telescopic cylinders 9 with their output ends facing upwards are fixedly connected to the lower surface of the movable lower plate 7, and their output ends pass through the movable lower plate 7 and are connected to the movable middle plate 5. Specifically, when the output ends of the SC telescopic cylinders 9 extend or retract, because the movable middle plate 5 is connected to the slide rail 3, the movable lower plate 7 and the movable upper plate 6 descend or rise synchronously, which can smoothly place the take-up roller B4 onto the rotating shaft of the winding machine 2, making centering efficient and convenient.

[0019] The upper surface of the movable upper plate 6 is fixedly connected to symmetrically arranged guide rods 14 via a fixing block 18. An inverted trapezoidal connecting plate 13 is provided on each side of the fixing block 18, and the connecting plate 13 is slidably connected to the corresponding guide rod 14. A support seat 10 is fixedly connected to the upper part of each connecting plate 13. Multiple evenly distributed hinge seats 11 are fixedly connected to the support seats 10. Support rollers B12 are rotatably connected to each hinge seat 11, and the take-up roller B4 is placed between the symmetrically arranged support rollers B12. Specifically, when the two connecting plates 13 move closer or further away simultaneously on the guide rods 14, the two symmetrical support rollers B12 will move closer or further away simultaneously. If the support rollers B12 move closer to each other, it meets the usage requirements when the take-up roller B4 is installed on the winding machine 2. If the support rollers B12 move further away from each other, it meets the material feeding requirements when the take-up roller B4 is wound with the strip material 300, preventing instability of the center of gravity when the support roller B12 carries the take-up roller B4, thus avoiding personal safety and economic losses.

[0020] A bidirectional lead screw 15 is fixedly mounted on the upper surface of the upper plate 6 via a bearing seat, and both ends of the bidirectional lead screw 15 are threadedly connected to two connecting plates 13 respectively. A servo motor 17 is fixedly mounted on the lower surface of the upper plate 6. The output end of the servo motor 17 drives the bidirectional lead screw 15 through the cooperation of a sprocket and a chain. A through slot 16 is provided on the middle plate 5 corresponding to the position of the servo motor 17 to avoid motion interference. Specifically, when the servo motor 17 drives the bidirectional lead screw 15 to rotate in both directions through the sprocket and chain, the bidirectional lead screw 15 can be used to drive the connecting plates 13 to move closer or further away synchronously, thereby adjusting the distance between the support rollers B12. This achieves the function of stabilizing the winding rollers B4 before or after the winding strip 300. The structure is simple and easy to use.
