Description

Technical Field

[0001] This utility model relates to the field of rewinding machine technology, and in particular to a slitting rewinding machine. Background Technology

[0002] A slitting and rewinding machine is a device used to slit large rolls of raw materials to a set width and rewind the slit materials into new rolls. It is mainly used in the packaging, printing, paper, and film industries. The slitting and rewinding machine can cut large rolls of material into smaller, compliant widths as needed and rewind the slit small rolls. By slitting and rewinding, raw materials can be transformed into small rolls of material that are easy to store and transport.

[0003] Currently, some existing slitting and rewinding machines do not allow for quick replacement of the slitting cutter shaft. When the cutter shaft wears out or malfunctions, it may require a long time for repair and replacement, resulting in excessive downtime and affecting production efficiency. Furthermore, different production tasks may require different types of cutter shafts, and the inconvenience of quick cutter shaft replacement may affect production flexibility.

[0004] Therefore, those skilled in the art have provided a slitting rewinding machine to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a slitting and rewinding machine. A connecting spring, after the rotating shaft is inserted into the cutter shaft, drives the moving block to move in the opposite direction, making it in close contact with the inner side of the placement groove. Simultaneously, a fixing ring secures the position of the pressing plate, thereby connecting the rotating shaft and the cutter shaft. This facilitates quick replacement of different cutter shafts. The guide wheel's left-right and up-down distances can be adjusted via threaded blocks and threaded rods, providing better guidance during rewinding.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A slitting and rewinding machine includes a base, with support plates movably connected to both sides of the upper end of the base, and fixed plates fixedly connected to both sides of the upper end of the base. A quick-connect structure is provided between the support plates on both sides, and a roller is provided at both the upper and lower ends between the fixed plates on both sides. A guide structure is provided between the fixed plates on both sides.

[0008] The quick-connect structure includes a cutter shaft that rotates between two support plates. A placement groove is provided at the center of one side of the cutter shaft. A rotating shaft is rotatably connected to one side of the support plate. Sliding grooves are provided at the upper and lower ends of the rotating shaft near the cutter shaft. A moving block is slidably connected inside the sliding groove. A pressing plate is fixedly connected to the upper end of one side of the moving block. The pressing plate slides inside the rotating shaft. A fixing ring is slidably connected to the outside of the rotating shaft.

[0009] The above technical solution facilitates the cutting of raw materials by setting the cutter shaft, thereby obtaining smaller pieces of material. The setting of the rotating shaft facilitates connection with the cutter shaft, thereby driving the cutter shaft to rotate. The setting of the moving block facilitates its movement and close contact with the inner side of the placement groove, thereby connecting the rotating shaft and the cutter shaft. The setting of the fixing ring facilitates the fixing of the position of the pressing plate, thereby preventing the plate from causing the moving block to slide.

[0010] Furthermore, the guide structure includes two bidirectional threaded screws that rotate between two fixed plates. Threaded blocks are threadedly connected to both sides of the outer wall of each bidirectional threaded screw. A fixed seat is fixedly connected to the upper end of each threaded block. A movable plate is slidably connected inside the fixed seat. Guide wheels are rotatably connected to one side of the lower end of the movable plate and inside the fixed seat.

[0011] The above technical solution allows the bidirectional threaded screw to rotate and move the threaded block on the rod inward or outward simultaneously, thereby adjusting the distance between the two sides of the guide wheel. The movable plate allows it to move inside the fixed seat, thereby moving the guide wheel on one side. The guide wheel helps to guide the small sections of material being rewound, thus facilitating better rewinding.

[0012] Furthermore, a connecting spring is fixedly connected to the bottom of the slide groove, and one side of the connecting spring is fixedly connected to the moving block;

[0013] The above technical solution allows the connecting spring to facilitate the reverse movement of the moving block after being squeezed, thereby ensuring that one side of the block is in close contact with the inside of the placement groove.

[0014] Furthermore, the front and rear ends of the moving block are fixedly connected to limit blocks, and the front and rear ends of the sliding groove are provided with limit grooves.

[0015] The above technical solution uses a limiting block and a limiting groove to limit the sliding of the moving block.

[0016] Furthermore, a No. 1 motor is provided on one side of the support plate, and the output end of the No. 1 motor passes through the support plate and is fixedly connected to the rotating shaft.

[0017] The above technical solution allows the No. 1 motor to drive the rotating shaft and the cutter shaft to rotate during operation.

[0018] Furthermore, a second motor is provided on the side of the fixing plate away from the bidirectional threaded screw, and the output end of the second motor passes through the fixing plate and is fixedly connected to the bidirectional threaded screw;

[0019] The above technical solution allows the No. 2 motor to drive the bidirectional threaded screw to rotate during operation.

[0020] Furthermore, multiple guide rods are fixedly connected between the two fixing plates, and the guide rods pass through the threaded block;

[0021] The above technical solution allows the threaded block to slide on its outer side by setting a guide rod, thereby guiding its movement.

[0022] Furthermore, a threaded rod is internally threaded on the side of the fixed seat away from the threaded block, and one side of the threaded rod is rotatably connected to the movable plate;

[0023] The above technical solution allows the threaded rod to rotate and move the movable plate, thereby adjusting the distance between the upper and lower sides of the guide wheel.

[0024] The present invention has the following beneficial effects:

[0025] 1. The present invention discloses a slitting rewinding machine, which, compared with existing rewinding machines, facilitates quick connection of the cutter shaft and the rotating shaft through the setting of the moving block. After pressing the pressing plate inward, the moving block is inserted into the cutter shaft. Releasing the plate causes the connecting spring to drive the moving block to move in the opposite direction, so that one side of it is in close contact with the inner side of the placement groove. The position of the pressing plate is fixed by a fixing ring to prevent the pressing plate from driving the moving block to move. The quick connection of the cutter shaft facilitates its replacement, shortens maintenance and replacement time, and improves production flexibility.

[0026] 2. The slitting rewinding machine proposed in this utility model, compared with the existing rewinding machine, facilitates the guidance of materials during rewinding by setting guide wheels. When the bidirectional threaded screw rotates, the threaded blocks on both sides move inward or outward at the same time, thereby driving the guide wheels on both sides to move. Rotating the threaded screw causes it to rotate inside the fixed seat, and drives the movable plate to move, thereby adjusting the distance between the upper and lower guide wheels. This makes it convenient to adjust the position of the guide wheels according to the size of the small piece of material, so as to better play the guiding role. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figure 1-3 One specific embodiment provided by this utility model:

[0036] A slitting and rewinding machine includes a base 1, with support plates 2 movably connected to both sides of the upper end of the base 1, and fixed plates 5 fixedly connected to both sides of the upper end of the base 1. A quick-connect structure 3 is provided between the two support plates 2, and a roller 6 is provided at both the upper and lower ends between the two fixed plates 5. A guide structure 4 is provided between the two fixed plates 5.

[0037] The quick-connect structure 3 includes a cutter shaft 301, which rotates between two support plates 2. A placement groove 302 is provided at the center of one side of the cutter shaft 301. A rotating shaft 303 is rotatably connected to one side of the support plate 2. A motor 311 is provided on one side of the support plate 2. The output end of the motor 311 passes through the support plate 2 and is fixedly connected to the rotating shaft 303. Sliding grooves 304 are provided at the upper and lower ends of the rotating shaft 303 near the cutter shaft 301. A moving block 305 is slidably connected inside the sliding groove 304. Limiting blocks 309 are fixedly connected to the front and rear ends of the moving block 305. Limiting grooves 310 are provided at the front and rear ends of the sliding groove 304. A connecting spring 306 is fixedly connected to the bottom of the sliding groove 304. One side of the connecting spring 306 is fixedly connected to the moving block 305. A pressing plate 307 is fixedly connected to the upper end of one side of the moving block 305. The pressing plate 307 slides inside the rotating shaft 303. A fixing ring 308 is slidably connected to the outside of the rotating shaft 303.

[0038] Specifically, the cutter shaft 301 facilitates the cutting of raw materials to obtain smaller pieces of material. The rotating shaft 303 facilitates connection with the cutter shaft 301, causing the cutter shaft 301 to rotate. The motor 311 facilitates the rotation of both the rotating shaft 303 and the cutter shaft 301 during operation. The moving block 305 facilitates its movement to make close contact with the inner side of the placement groove 302, thus connecting the rotating shaft 303 and the cutter shaft 301. The limiting block 309 and the limiting groove 310 limit the sliding of the moving block 305. The connecting spring 306 facilitates the reverse movement of the moving block 305 after being squeezed, so that one side of it makes close contact with the inner side of the placement groove 302. The fixing ring 308 fixes the position of the pressing plate 307, preventing the plate from causing the moving block 305 to slide.

[0039] Reference Figure 1 , Figure 4 and Figure 5 The guide structure 4 includes two bidirectional threaded screws 401, which rotate between two fixed plates 5. A second motor 404 is provided on the side of the fixed plate 5 away from the bidirectional threaded screws 401. The output end of the second motor 404 passes through the fixed plate 5 and is fixedly connected to the bidirectional threaded screws 401. Threaded blocks 402 are threadedly connected to both sides of the outer wall of the bidirectional threaded screws 401. Multiple guide rods 403 are fixedly connected between the two fixed plates 5. The guide rods 403 pass through the threaded blocks 402. A fixed seat 405 is fixedly connected to the upper end of the threaded blocks 402. A movable plate 407 is slidably connected inside the fixed seat 405. Guide wheels 406 are rotatably connected to one side of the lower end of the movable plate 407 and inside the fixed seat 405. A threaded rod 408 is threadedly connected to the side of the fixed seat 405 away from the threaded blocks 402. One side of the threaded rod 408 is rotatably connected to the movable plate 407.

[0040] Specifically, the second motor 404 is designed to drive the bidirectional threaded screw 401 to rotate during operation. The bidirectional threaded screw 401, upon rotation, drives the threaded block 402 on the rod to move inward or outward simultaneously, thereby adjusting the distance between the two sides of the guide wheel 406. The guide rod 403 allows the threaded block 402 to slide on its outer side, thus guiding its movement. The movable plate 407 is designed to move within the fixed base 405, thereby driving the guide wheel 406 on one side to move. The guide wheel 406 guides the small sections of material being rewound, facilitating better rewinding. The threaded rod 408, upon rotation, drives the movable plate 407 to move, thereby adjusting the distance between the upper and lower sides of the guide wheel 406.

[0041] Working principle: When the cutter shaft 301 needs to be replaced, the support plate 2 on one side can be removed, the bolts removed, and the fixing ring 308 slid to one side. The pressing plate 307 is then pressed inwards to move the moving block 305 inwards, while simultaneously pulling the cutter shaft 301 to one side. This causes a portion of the rotating shaft 303 and the moving block 305 to disengage from the placement groove 302, allowing for quick disassembly of the cutter shaft 301 for easy maintenance or replacement of worn shafts. For installation, the pressing plate 307 is pressed inwards to move the moving block 305 inwards. The moving block 305 is inserted into the cutter shaft 301. Loosening the plate causes the compressed connecting spring 306 to move the moving block 305 in the opposite direction, making one side of it tightly contact the inside of the placement groove 302. The surface of the moving block 305 is provided with a rubber pad to increase friction. The fixing ring 308 is slid to the underside of the pressing plate 307 and connected with bolts, thereby fixing the position of the pressing plate 307 and preventing the moving block 305 from sliding after the plate moves inward. After installing and fixing the support plate 2 on one side, the first motor 311 can be started. Then, the rotating shaft 303 drives the cutter shaft 301 to rotate, introducing the raw material to be slit and rewound between the auxiliary roller and the cutter shaft 301, and guiding and fixing the small section of material to be rewound. The position of the two threaded blocks 402 is adjusted according to the size of the small section of material, causing the second motor 404 to drive the bidirectional threaded screw 401 to rotate, so that the threaded blocks 402 on both sides move inward or outward at the same time, thereby driving the guide wheel 406 to move until it matches the size of the small section of material. The distance between the two guide wheels 406 is adjusted according to the different thicknesses of the material, and the threaded rod 408 is rotated to make it rotate inside the fixed seat 405. Since it is rotatably connected to the movable plate 407, it can drive the movable plate 407 to move, thereby driving the guide wheel 406 on one side to move, until it is convenient for the material to pass between the two wheels, thus helping to guide and make the small section of material better complete the rewinding. The two sides of the small section of material are passed through the guide wheel 406, and one side of the material is fixed on the roller outside the roll 6, so that the cutter shaft 301 and the roll 6 can rotate to slit and rewind.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
