AI Technical Summary
In a rotary die-cutting machine, the material strip is easily entangled on the suction roller due to its suction effect, resulting in the strip wrapping problem.
The meshing of the first and second gear rings with the gears causes the suction traction roller and the anti-winding traction roller to rotate in the same direction. The anti-winding traction roller pulls the material belt away from the suction traction roller, and the partitioned suction plate reduces the suction force of the downstream suction hole, thus achieving smooth conveying of the material belt.
This effectively prevents the material belt from getting tangled on the suction roller, ensuring smooth material belt transport and reducing the occurrence of belt wrapping.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of traction device technology, and in particular to a suction traction device with anti-tangle function. Background Technology
[0002] In a rotary die-cutting machine, a suction roller is used to pull the material belt forward. The suction roller has a ring of suction holes around its circumference. Some of the suction holes come into contact with the material belt and simultaneously adsorb it. Then, the suction roller rotates to drive the material belt forward. However, the downstream suction holes will continue to adsorb the material belt, causing the material belt to be adsorbed and wrapped around the suction roller before it leaves the suction roller, thus causing the belt to wrap around.
[0003] Therefore, a suction traction device with anti-tangle function is needed to solve the above problems. Utility Model Content
[0004] This utility model proposes a suction traction device with anti-winding function. Through the meshing of the first and second gear rings with the gear, the suction traction roller and the anti-winding traction roller rotate in the same direction. The rotating anti-winding traction roller moves the material belt downstream of the suction traction roller away from the suction traction roller, so that the material belt downstream of the suction traction roller is detached from the suction traction roller's adsorption, thereby avoiding the occurrence of wrapping.
[0005] The technical solution of this utility model is implemented as follows:
[0006] A suction traction device with anti-winding function includes a mounting frame. Along the forward direction of the conveyor belt, a suction traction roller and an anti-winding traction roller are rotatably mounted on the mounting frame. The suction cylinder of the suction traction roller is provided with a first toothed ring, and the anti-winding traction roller is provided with a second toothed ring. A gear is rotatably mounted on the mounting frame. Both the first toothed ring and the second toothed ring mesh with the gear. The gear is connected to a drive mechanism that drives the gear to rotate. The suction traction roller and the anti-winding traction roller are arranged in parallel.
[0007] As a preferred technical solution, the suction traction roller includes a suction shaft fixedly installed on the mounting frame, a suction channel is provided on the suction shaft, a suction cylinder is rotatably installed on the suction shaft, a plurality of suction holes are provided on the suction cylinder, a suction cavity is provided inside the suction cylinder, and the suction holes and the suction channel are all connected to the suction cavity.
[0008] As a preferred technical solution, two fixed disks are fixedly installed on the outer circumferential surface of the suction shaft. The two fixed disks are respectively disposed at both ends of the suction cavity. The outer circumferential surface of the fixed disk is adapted to the inner circumferential surface of the suction cylinder. Two partitioned suction plates are fixedly installed between the two fixed disks.
[0009] As a preferred technical solution, the two partitioned suction plates are respectively disposed on both sides of the suction shaft. The partitioned suction plates divide the suction chamber into an upper suction chamber and a lower suction chamber. The upper suction chamber is connected to the suction channel. Both partitioned suction plates are provided with a plurality of through holes for connecting the upper suction chamber and the lower suction chamber.
[0010] As a preferred technical solution, the driving mechanism is an electric motor.
[0011] By adopting the above technical solution, the beneficial effects of this utility model are as follows:
[0012] Because the suction traction device with anti-winding function includes a suction traction roller and an anti-winding traction roller, during the use of this device, the material belt rests against the top of the suction traction roller, and a negative pressure is formed at the suction hole at the top of the suction traction roller. The material belt is attracted to the top of the suction traction roller. As the suction traction roller rotates, the material belt is conveyed downstream, thereby realizing the traction of the material belt. At the same time, the anti-winding traction roller rotates. Due to the meshing of the first and second gear rings with the uniform gear, the anti-winding traction roller and the suction traction roller rotate in the same direction. The rotating anti-winding traction roller will move the material belt downstream of the suction traction roller away from the suction traction roller, so that the material belt downstream of the suction traction roller is detached from the suction traction roller's attraction, thereby avoiding the occurrence of winding.
[0013] Because the suction traction device with anti-winding function includes a suction traction roller, two partitioned suction plates divide the suction chamber into an upper suction chamber and a lower suction chamber. Since the suction channel is connected to the upper suction chamber, the suction force of the suction holes on the outside of the lower suction chamber is weakened, thereby reducing the adsorption of the material belt downstream of the suction traction roller by the lower suction chamber. At the same time, under the separation of the suction traction roller, the material belt downstream of the suction traction roller is allowed to detach from the adsorption of the suction holes. As the upstream conveyor belt is conveyed downstream by the suction traction roller, the material belt that has detached from the adsorption of the suction holes also moves downstream, thereby realizing the traction of the conveyor belt.
