Linear cutter mechanism for winding machine

Abstract

The invention discloses a linear cutter mechanism for a winding machine. The linear cutter mechanism comprises a kiss roller for being attached to winding rollers and cutters for cutting belt materials. The two ends of the kiss roller are provided with linear driving mechanisms for driving the kiss roller to move along a straight line correspondingly. Each linear driving mechanism comprises a first air cylinder and a second air cylinder, and the axis of a piston rod of the first air cylinder and the axis of a piston rod of the second air cylinder are parallel to each other. The piston rods of the first air cylinders are provided with a connecting plate. The piston rods of the second air cylinders are connected with the connecting plate. Cylinder bodies of the second air cylinders are provide with an installation plate. Third air cylinders with cylinder bodies being in hinged connection with the installation plate are arranged on the installation plate. The kiss roller is rotationally installed on the installation plate in a matched mode. The two ends of each cutter are provided with connecting rods correspondingly. The connecting rods are rotationally installed on the kiss roller in a matched and sleeving mode. Piston rods of the third air cylinders are in hinged connection with the connecting rods. According to the linear cutter mechanism for the winding machine, not only can the using requirement be met, but also the impact force during cutting is small, and the effect that the belt materials can be attached to the winding rollers can be ensured.

Description

technical field [0001] The invention belongs to the technical field of strip coiling mechanisms, and in particular relates to a linear cutter mechanism for a winder. Background technique [0002] The winding and unwinding mechanism is the unwinding or rewinding part of the coil material processing production line. It is mainly used to mechanically unwind the coiled raw materials during unwinding, and is mainly used to mechanically wind the raw materials into coils during winding. The winding and unwinding mechanism is widely used in paper rolls, cloth rolls, plastic rolls and metal coil processing production lines, and the design is diversified according to actual process requirements. [0003] The roll frame of the existing winder is provided with two winding rollers. When one of the winding rollers is finished winding, the roller frame is driven to rotate so that the winding roller rotates to the unloading station, while the other The first winding roller then rotates to ...

AI Technical Summary

Problems solved by technology

Although the existing cutter mechanism can meet the requirements of use to a certain extent, due to the long arc motion stroke of the cutter, there is a large impact force and hysteresis when it cuts the strip; After being cut off, it cannot fit well with the new winding roller, so that the winding work cannot be carried out smoothly
