Corrugation elimination device for thin films

Abstract

The invention discloses a corrugation elimination device for thin films, and relates to the technical field of thin film production equipment. In order to achieve the aims that corrugation eliminationeffect is guaranteed and meanwhile products are prevented from being influenced by temperature sudden decrease or sudden increase, the corrugation elimination device specifically comprises a coolingchamber, 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 comprises a refrigerating machine,a heating machine and two temperature control channels; the outer walls of the bottoms of the refrigerating machine and the heating machine are fixed to the outer walls of the tops of the cooling chamber and the hot air chamber through screws correspondingly; and the top ends of the two temperature control channels are connected to the output ends of the refrigerating machine and the heating machine correspondingly. The temperature is controlled in a manner of alleviating the temperature difference, the corrugation elimination effect is guaranteed, and meanwhile products are prevented from being influenced by temperature sudden decrease or sudden increase; and specifically, through the arrangement of a lower air flue and an auxiliary air supply mechanism, the temperature difference betweenthe temperature of the positions, close to inlets and outlets, in the cooling chamber and the hot air chamber and the outside temperature can be reduced, and the treatment effect and reliability areimproved.

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 ...

AI Technical Summary

Problems solved by technology

The cold air chamber and hot air chamber in the above patents have the following disadvantages: Although they can provide a certain cold and hot environment, they may cause the temperature difference between the inlet and outlet to be large, and the temperature rise and fall will not be smooth, which will affect the treatment effect of the film.
