Description
Technical Field
The utility model belongs to the technical field of film production, and particularly relates to a gap adjustment device for a clamping opening of a transverse zipper.
Background
The biaxial stretching method is used as one of the production methods of BOPP films, is suitable for mass production due to mature equipment and high production efficiency, and is adopted by most enterprises. The biaxial stretching method is to make the melt of polypropylene PP into sheet or thick film through a long and narrow machine head, then to stretch the film transversely and longitudinally at certain temperature and set speed in a special stretcher, and to make the film through proper cooling or heat treatment or special processing (such as corona, coating, etc.).
Currently, in the two-way stretching apparatus on the market, the most critical component in the transverse stretching system (TDO) or the simultaneous transverse stretching (TDO) and longitudinal stretching (MDO) is the chain clamp, which is mainly used to clamp the edge of the film, and stretch the film in the transverse and/or longitudinal directions while advancing the film. However, long-time operation and improper operation gradually cause damage to the chain clamp, so that the gap between the clamping openings of the chain clamp becomes large, and further the chain clamp cannot clamp the film, resulting in loosening of the film. In the actual production process, sudden clamping release can be caused, sometimes even repeated halts can be caused, and the production progress and the quality of the film products are seriously influenced. In order to solve this problem, a conventional method is to hammer the chain clip with a hammer so that the gap between the clip openings of the chain clip is reduced. The method has low efficiency, and is time-consuming and labor-consuming. Therefore, the utility model aims at the problem, and designs a device for adjusting the gap of the clamping mouth of the horizontal zipper, which can adjust the gap of the clamping mouth by exerting pressure on the clamping arm of the zipper through a hydraulic rod to enable the clamping arm to generate mechanical deformation under the condition that the gap of the clamping mouth of the horizontal zipper exceeds 0.15-0.2mm, so as to maintain the zipper.
