Filter cloth processing technology and device

Abstract

The invention discloses a filter cloth processing technology and device. The filter cloth processing technology comprises the following steps of raw material selecting, thread twisting, treating through a warping machine, gray fabric weaving, hot air drying, calendaring, ultrasonic edge cutting, gluing and steel button knotting, joint treatment and packaging. A raw material adopts a polyester product; the step of thread twisting is completed at a time by adopting three threads and one strand; after grey cloth enters a heating cavity, a gear driving part drives a moving rod to do horizontal reciprocating motion and can drive a plurality of sets of air outlet plates to swing around the axis of a mounting base at the same time, and air blowing openings conduct hot air drying on filter cloth in the reciprocating swing process, so that the filter cloth is heated evenly, and the heating and drying effect is improved; a cooling cavity is arranged behind the heating cavity, and the filter cloth passes through the heating cavity so as to be heated and then enters the cooling cavity so as to be rapidly cooled, so that the filter cloth is ensured to have certain tension; and a balance cavity can use air exhausted from the heating cavity to blow air to the cooled filter cloth, so that the temperature of the filter cloth is balanced.

Description

technical field [0001] The invention relates to the technical field of filter cloth processing, in particular to a filter cloth processing technology and device. Background technique [0002] The high-efficiency filter cloth made of high-quality ultra-fine fiber can easily meet the performance requirements of high-precision filtration in different industries. During the processing of the filter cloth, a hot air drying device is required to dry the woven gray cloth, which is beneficial for subsequent processing. [0003] In the existing patent notification number CN 110631343 B of a hot air drying device for non-woven fabric production, the first drying component dries the non-woven fabric for the first time through rotating hot air, which can effectively blow off moisture; The second drying component heat-presses the non-woven fabric through the first heat-pressing roller and the second heat-pressing roller injected with heat-conducting oil. During the heat-pressing process...
