Problems solved by technology

However, the existing CPP film winder has the following problems: 1. Since the winder cannot achieve precise positioning with the unloading device when it swings, the existing winder cannot realize automatic unloading during the swing period ; 2. The existing pendulum drive device generally drives the pendulum to swing through the eccentric wheel transmission mechanism, and the transmission stability and accuracy are lacking, which affects the winding effect; 3. When the pendulum moves laterally through the roller guide mechanism, the pendulum It will be supported by the sheave, and when the pendulum swings, it will drive the sheave to roll along the guiding direction of the guide rail. In long-term use, wear will occur between the guide groove on the sheave and the guide rail, which will affect the stability of the pendulum deflection sex

Abstract

The invention discloses a CPP film winding machine. The CPP film winding machine comprises a swing frame, an edge clamping assembly, a guide roller assembly, an edge cutting assembly, a traction roller assembly, a tension roller assembly, a floating roller assembly used for controlling the winding flatness of a film, a fly-cutter assembly, a wind-up roll driving assembly, a roll changing assembly,an air expansion shaft clamping and exhausting device, a roll unloading trolley, an automatic film roll transferring device, rolling wheel devices, a swing frame driving device, a linear displacementsensor and a displacement detection device; and the linear displacement sensor feeds back a signal to the roll unloading trolley, so that the roll unloading trolley moves corresponding to the position of the swing frame during roll unloading to realize accurate positioning between the roll unloading trolley and an air expansion shaft. According to the CPP film winding machine, the swing frame issmooth and reliable in deflection movement, the film thickness deviation can be automatically adjusted, and the end face of a wound film is neat and free of wrinkling; and when the winding machine isused for winding, the swing frame and the roll unloading trolley can be accurately positioned, and automatic roll unloading by the swing frame in the swing period is achieved.

Description

technical field [0001] The invention relates to the technical field of film winding machines, in particular to a CPP film winding machine. Background technique [0002] CPP film is made of polypropylene as the main raw material, and is made by extrusion casting through a die head. During the film winding process, due to the pulling speed, tension or uneven thickness of the film when the winder pulls the film, the film will move left and right and deviate in one direction when the film is pulled and wound, resulting in the film being wound. Sometimes wrinkled or irregular end surface, resulting in waste of film and difficulties in subsequent processing. Therefore, a winding and deviation correction device will be added in the film winder. The existing winding and deviation correction device mainly includes a swing frame, a roller guide mechanism arranged on both sides of the swing frame, a drive device for the swing frame, and a device for detecting the deviation of the wind...
