Background technique

In the production process of strip products such as paper rolls, cloth rolls, and plastic film rolls, a winder is needed to wind and unwind the material of the product. The existing winding machine is generally provided with a rotatable roll frame, and the roll frame is provided with two or more coiling rolls. When one of the coiling rolls completes the strip winding or unwinding work, the roll frame is driven to rotate, so that the coiling roll leaves the working station, and the strip is cut off by the cutter structure, so that the material is pasted on the other side. On a roll that enters the work station to realize the uninterrupted winding or unwinding of the strip by the winding machine.

The existing cutter structure generally includes a cutter arm that is rotatably connected to the frame and a cutter fixed at the end of the cutter wall. The cutter arm rotates and the strip is cut off by the cutter. However, in this method of cutting the strip, the feed route of the cutter is an arc. In order to prevent the rotation of the cutter arm from interfering with the rotation of the winding roller, the cutter arm needs to have a sufficient length. It is easy to cause the cutter located at the end of the cutter arm to vibrate violently. At the same time, the cutter has a large range of motion and speed during the rotation of the cutter arm, so that the cutter has a greater vibration when cutting the strip. The impact force causes the cutter to loosen easily during use, and the strip cannot be cut off well, and then the strips on several winding rollers are wound together, affecting the normal operation of the winding machine.
