Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a traction roller follower synchronization mechanism and a traction knife seat thereof. Background Art

[0002] like Figure 1 As shown, the rotation of the drive shaft and the power transmission on the traction cutter seat of the existing circular knife machine mostly rely on the gears on the drive shaft. When the traction roller and the bottom roller are traction-conveyed thinner materials, the gears on the two roller bodies are meshed at position A. At this time, the distances from the centers of the gears on the two roller bodies to position A are equal, that is, the rotation radius is equal. Since the speed of any point on an object when it makes a circular motion about a fixed axis is called the linear velocity, the linear velocity is used to measure the speed of the object's rotation, and the linear velocity is equal to the product of the angular velocity and the rotation radius. Therefore, when the traction roller and the bottom roller are traction-conveyed thinner materials, the conveying linear velocities of the traction roller and the bottom roller are consistent.

[0003] like Figure 2 As shown, depending on the product, the thickness of the material pulled by the traction knife seat is different. When the thickness of the material to be pulled and transported between the traction roller and the bottom roller is large, in order to increase the traction gap between the traction roller and the bottom roller to facilitate the passage of the material, the traction roller will be moved upward in the vertical direction through the pressure knife assembly, so that the traction roller is away from the bottom roller, and the meshing position of the gears on the two roller bodies is changed, that is, the two gears are meshed at point B, which makes the distance from the center of the gear on the traction roller to point B greater than the distance from the center of the gear on the bottom roller to point B. The rotation radius of the two gears is different, so that the linear speeds of the traction roller and the bottom roller are inconsistent. When the material is too thick, the gears on the two roller bodies will be disengaged and unable to mesh. The traction roller is a passive rotation, so the traditional traction knife seat is only suitable for traction of thin materials. As the thickness of the material increases, there will be a certain speed difference between the traction roller and the bottom roller. For the transportation of multi-layer materials, there may be a certain hysteresis, and the synchronous traction of the material cannot be achieved.

[0004] Therefore, a traction roller follower synchronization mechanism and a traction knife seat thereof are needed to solve the above problems. Utility Model Content

[0005] The utility model provides a traction roller follower synchronization mechanism and a traction knife seat thereof, which use a follower gear as an intermediate gear to make the traction rubber roller and the traction bottom roller always run synchronously in the same direction, and also realize the adjustable gap between the traction rubber roller and the traction bottom roller, thereby respectively meeting the synchronous conveying of thinner multi-layer materials and thicker multi-layer materials.

[0006] The technical solution of the utility model is achieved in this way:

[0007] The traction roller follower synchronization mechanism includes an intermediate gear mounting plate and a fixed plate respectively fixedly mounted on the traction knife seat, an intermediate gear is rotatably mounted on the intermediate gear mounting plate, a follower gear mounting plate is hingedly connected to the intermediate gear mounting plate, the intermediate gear and the hinge point of the follower gear mounting plate are coaxially arranged, a follower gear is rotatably mounted on the follower gear mounting plate, the intermediate gear is meshed with the follower gear, and a reset component is provided between the follower gear mounting plate and the fixed plate.

[0008] As a preferred technical solution, the reset assembly includes a guide shaft installed on the follower gear mounting plate, a guide groove is provided on the fixed plate, the other end of the guide shaft is constrained and installed in the guide groove, a compression spring is sleeved on the guide shaft, and the compression spring is arranged between the follower gear mounting plate and the fixed plate.

[0009] As a preferred technical solution, a rotating shaft is rotatably mounted between the intermediate gear mounting plate and the follower gear mounting plate, and the intermediate gear is arranged on the rotating shaft.

[0010] As a preferred technical solution, the intermediate gear mounting plate is mounted with a mounting column via a locking bolt, and the mounting column is mounted on the traction knife seat.

[0011] The traction knife seat includes the traction roller follower synchronization mechanism, and the traction knife seat also includes a traction mounting frame, and the traction mounting frame is installed with a transmission shaft, a traction bottom roller and a traction rubber roller from bottom to top. The transmission shaft is provided with a first transmission gear, and the traction bottom roller is provided with a second transmission gear. The first transmission gear is meshed with the second transmission gear, and the second transmission gear is meshed with the intermediate gear. The traction rubber roller is provided with a third transmission gear, and the third transmission gear is meshed with the follower gear.

[0012] As a preferred technical solution, the traction rubber roller is slidably mounted on the traction mounting frame in a vertical direction through a knife pressing assembly, the knife pressing assembly includes a horizontally arranged lower mounting plate, the traction rubber roller is rotatably mounted on the bottom of the lower mounting plate through a pair of bearing boxes, an upper mounting plate is horizontally arranged above the lower mounting plate, the upper mounting plate is installed on the top of the traction mounting frame, an adjusting screw is vertically arranged on the upper mounting plate, the lower end of the adjusting screw passes through the upper mounting plate and is connected to the lower mounting plate, a pair of guide columns and a pair of vertical guide shafts are symmetrically arranged between the upper mounting plate and the lower mounting plate, each of the vertical guide shafts is sleeved with a return spring, and each of the return springs is arranged between the upper mounting plate and the lower mounting plate

[0013] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0014] Since the traction roller follower synchronization mechanism and its traction knife seat include a support assembly, when the utility model is used to pull the material, the adjusting screw is first rotated to make the traction rubber roller move upward in the vertical direction, and then the material is placed between the traction bottom roller and the traction rubber roller, and the adjusting screw is rotated in the direction to compact the material, and the driving motor is started to start the material pulling. In the process of the traction rubber roller moving in the vertical direction, the follower gear mounting plate is pushed by the compression spring to approach the third transmission gear, so that the follower gear mounting plate rotates with the rotating shaft as the central axis, and the follower gear rotates with the follower gear mounting plate, so that the follower gear is always meshed with the third transmission gear, ensuring that the rotation radius of the third transmission gear and the follower gear remains unchanged, thereby ensuring that the linear speed of the second transmission gear and the third transmission gear is consistent, that is, the traction bottom roller and the traction rubber roller rotate synchronously. In the utility model, the follower gear is used as an intermediate tooth, so that the traction rubber roller and the traction bottom roller always run synchronously in the same direction, and the gap between the traction rubber roller and the traction bottom roller is adjustable, thereby respectively meeting the synchronous conveying of thinner multi-layer materials and thicker multi-layer materials.
