Description

Technical Field

[0001] This utility model relates to winding equipment, specifically to a high-speed rewinding device. Background Technology

[0002] A rewinding machine is a device used to rewind various types of aluminum foil, silicone paper, etc., into small rolls for final product output. (Chinese Patent Document Publication No.: CN) (Published on September 17, 2021) discloses a multi-station rewinding mechanism for a rewinding machine, characterized in that: it includes a rewinding mechanism body, which is installed on the inner wall of the frame of a rewinding machine. The rewinding mechanism body includes a rotating spindle, which is rotatably mounted on the frame of the rewinding machine via the rotating spindle. A synchronous pulley is fixedly sleeved on one end of the rotating spindle. The synchronous pulley is connected to a first drive mechanism via a synchronous belt. The first drive mechanism is fixedly disposed at one end of the frame. The first drive mechanism drives the synchronous pulley to rotate via the synchronous belt, thereby driving the rotating spindle to rotate. A first turntable, a second turntable, and a third turntable are fixedly sleeved on both ends of the rotating spindle. Six segmented rotating seats are evenly embedded on the first turntable, and each segmented rotating seat is parallel to the rotating spindle. The segmented rotating seat includes a top shaft and a sliding bushing, the sliding bushing being slidably fitted onto the top shaft; six straight copper sleeves are evenly embedded between the second and third turntables, each straight copper sleeve containing a sliding rod, the sliding rod and the axis of the corresponding sliding bushing being on the same straight line; a first pushing assembly and a second pushing assembly are respectively provided at both ends of the frame; a hopper is provided at the upper right end of the first turntable, the hopper containing paper cores; when the rotating main shaft drives the segmented rotating seat to rotate to the rightmost side of the first turntable, the first pushing assembly pushes the sliding bushing toward the paper core, causing the paper core wrapped with paper material to fall; when the rotating main shaft drives the straight copper sleeve to rotate to the upper right side of the second turntable, the second pushing assembly pushes the sliding rod toward the paper core, causing the paper core falling from the hopper to be fitted onto the sliding rod.

[0003] The rewinding equipment with the above structure first puts the paper core onto the slide bar structure and then winds the paper material onto the paper core. After the winding is completed, the paper material is cut and the paper core is pushed out. This solution also requires the setting of paper core insertion and ejection structures, which makes the overall structure of the equipment more complex. Moreover, the insertion and ejection of the paper core are complicated and slow, which will also affect the rewinding efficiency of the rewinding machine. Utility Model Content

A cutting assembly is also provided at the winding station to cut the wound substrate. The rotating disk 4 can drive the wound air shaft to rotate to the discharge station. A labeling assembly 5 and a pushing assembly are provided at the discharge station. The labeling assembly is a common structure on the market and is prior art known to those skilled in the art. It is not an innovation of this application, so its specific structure will not be described in detail.

[0023] Furthermore, the unwinding assembly includes an unwinding shaft 7 and a first swing frame 10 hinged at one end to the frame. The first swing frame 10 is connected to a first swing drive assembly. A traction roller 2 and a first swing arm 11 are mounted on the first swing frame 10. The middle part of the first swing arm 11 is hinged to the first swing frame 10.

The first swing drive assembly includes a first cylinder 8 mounted on the frame, with its piston rod hinged to the first swing frame 10. The second swing drive assembly includes a second cylinder 9 mounted on the first swing frame 10, with its piston rod hinged to one end of the first swing arm 11. By adopting the above structure, controlling the first cylinder 8 can drive the first swing frame 10 to swing to the winding station or swing back to make way, facilitating the disassembly and maintenance of various components.

[0024] Furthermore, the pressing assembly includes a second swing frame 22, which is connected to a third swing drive assembly. The third swing drive assembly is a third cylinder 12, the cylinder body of which is mounted on the frame. The piston rod of the third cylinder 12 is hinged to the second swing frame 22. A pressing component is mounted on the second swing frame 22, which can press the substrate onto the air shaft 3. The pressing component is a pressing belt 14, which passes over a first pulley 15. The first pulley 15 is mounted on a first rotating shaft 16, and a second pulley 17 is connected to the first rotating shaft 16. A first transmission belt 18 passes over the second pulley 17 and a third pulley 19, which is mounted on a second rotating shaft 20. The second swing frame 22 is hinged to the second rotating shaft 20. The assembly also includes a second transmission belt 21, which passes over the third pulley 19 and a fourth pulley. The fourth pulley is connected to the output end of the first motor 23. With the above structure, the reciprocating swing control of the second swing frame 22 can be realized. At the same time, the belt pulley transmission structure drives the pressure belt 14 to move, so that the substrate sent from the unwinding assembly can move to the air shaft 3 under the guidance of the pressure belt 14 and be pressed on the air shaft 3 for winding.

[0025] Furthermore, the cutting assembly includes a cutting blade 24, which is mounted on a third swing frame 25. The third swing frame 25 is hinged to the frame and connected to a fourth swing drive assembly. The fourth swing drive assembly includes a fourth cylinder 26, the cylinder body of which is mounted on the frame, and the piston rod of which is hinged to the third swing frame 25.

[0026] Furthermore, it also includes a second motor 31, which is connected to a fifth pulley 32. A third transmission belt 33 is wound around the fifth pulley 32. One end of the air shaft 3 is equipped with a driven pulley 34. When the rotating disk 4 drives the air shaft 3 to rotate to the winding position, the driven pulley 34 on the air shaft 3 comes into contact with the third transmission belt 33, so that the third transmission belt 33 can drive the driven pulley 34 and the air shaft 3 to rotate. With the above structure, the air shaft 3 can be made to rotate at the winding position to realize the rewinding operation. At the same time, the air shaft 3 will stop rotating after leaving the winding position, which is convenient for subsequent labeling and ejection.

[0029] The working principle of this utility model is as follows: The large roll of substrate is first unwound by the unwinding assembly. The traction roller 2 and the first rubber roller 2 work together to pull the substrate to the winding station. At this time, the rotating disk 4 drives one of the air shafts 3 to rotate to the winding station, and the air shaft 3 is already in an outward expansion state. At the same time, the second swing frame 22 swings, so that the pressure belt 14 cooperates with the air shaft 3. The delivered substrate first contacts the pressure belt 14 and is pressed onto the air shaft 3 under the drive of the pressure belt 14. As the air shaft 3 rotates, winding continues. Then the second swing frame 22 swings back, so that the pressure belt 14... 4. Move away from the air shaft 3. After the air shaft 3 finishes winding, the cutting knife 24 cuts the unwound substrate from the substrate on the air shaft 3. The rotating disk 4 rotates one station angle, so that the next air shaft 3 rotates to the winding station. The second swing frame 22 swings again, so that the pressure belt 14 cooperates with the air shaft 3 to perform the winding operation. After the air shaft 3 finishes winding, it rotates to the discharge station. The labeling component 5 labels the roll substrate. Then the outer expansion ring of the air shaft 3 retracts, releasing the roll substrate. The pusher arm 9 pushes the roll substrate off the air shaft 3 and drops it onto the discharge conveyor belt 6 for delivery.

[0030] This invention's structure, by setting up a pressing component, can directly press the unwound substrate onto the air shaft for winding, replacing the traditional structure of setting up the paper core before winding. This greatly simplifies the equipment structure, facilitates its production and assembly, and also simplifies the rewinding process, effectively improving the rewinding efficiency of the rewinding machine and enabling high-speed rewinding operations.
