Abstract

The invention discloses a corrugation elimination device for film, which relates to the technical field of film production equipment; in order to avoid the influence of the product due to a sudden drop or rise in temperature while ensuring the corrugation elimination effect; it specifically includes a cooling chamber and a hot air chamber and a temperature control mechanism, the cooling chamber is located on one side of the hot air chamber, the temperature control mechanism includes a refrigerator, a heating machine and two temperature control channels, and the bottom outer walls of the refrigerator and the heating machine are respectively fixed to the cooling chamber by screws and the top outer wall of the hot air chamber; the tops of the two temperature control passages are respectively connected to the output ends of the refrigerator and the heater. The present invention controls the temperature by easing the temperature difference, while ensuring the elimination effect of the ripples, it avoids the product being affected by the sudden drop or rise in temperature; specifically, by setting the lower air duct and the auxiliary air supply mechanism, the cooling chamber and the cooling chamber can be reduced. The temperature difference between the temperature at the position near the entrance and exit of the hot air chamber and the outside temperature improves the treatment effect and reliability.

Description

technical field

[0001] The invention relates to the technical field of film production equipment, in particular to a corrugation eliminating device for films. Background technique

[0002] There are many ways to form a film, such as calendering, casting, blow molding, stretching, etc. In recent years, to adapt to the continuous improvement of packaging requirements in the packaging industry, the quality requirements of films are also gradually increasing. However, during the production and manufacturing process of films, films often shrink due to cooling, which makes partial contact and adhesion between films. Thus, water ripples are generated, which seriously affects product quality.

[0003] After searching, the Chinese patent application number is CN201320123848.4, which discloses a thermoplastic polyurethane film ripple elimination device, which is characterized in that it includes a hot air chamber, and the hot air chamber is provided with a hot air chamber supporting ...
