Description

Rim charge recovery unit is used in wound film production

Technical Field

The invention belongs to the technical field of plastic recovery, and particularly relates to a rim charge recovery device for producing a winding film.

Background

The winding film is produced by melt-extruding plastic particles, cutting the plastic particles into small-specification winding films with different widths or the same width on the basis of a large film, and winding the small-specification winding films to a winding core. Typically an extruded large sheet of film can be slit into 5 different smaller sheets and wound on separate cores. The cut edge material film can be directly wound on the recovery winding core, and then is put into a crusher to be crushed into uniform small fragments for recovery. However, when the rim charge is recovered, the tensile degree performance of the rim charge film is lower, so that the rim charge film can be prevented from being broken by tightly winding the rim charge film when the rim charge is wound. Therefore, the winding cores are relatively loose in winding the side materials, and the recovery amount of the single winding core is small. For example, publication number CN119116218B discloses a rim charge recovery unit for wound film production, it adopts through starting first driving piece control capstan for wound film rim charge rotates to the position that is close to the crushed aggregates roller along with the wind-up roll, outwards takes out the capstan along with the wind-up roll, and the wound film of lapping will drop on the crushed aggregates roller, and this recovery unit can effectively reduce motor operating time through the start crushed aggregates roller of intermittent nature, thereby be favorable to reducing the operation energy consumption of equipment, and reach the purpose of the staff control equipment maintenance of being convenient for and use cost.

When the claw-knife type crushing roller breaks wound films, the film body is easily adsorbed by static influence to form clusters, so that the accumulation is caused at the feeding and discharging ports, the films are easily splashed and adhered to the cavity wall or the crushing roller, and the continuous operation time of the crusher is shortened.
