Humidification anti-static device

Abstract

A device for humidifying and removing static electricity, comprising a cotton conveying pipe, an upper cotton storage box, a lower cotton storage box and its air outlet of the upper cotton box, an air outlet of the lower cotton storage box, a dust exhaust duct, a fan, a pressure sensor and pressure parameter adjustment Device, humidifier and its PLC controller, A / D converter, ultrasonic generator and humidity sensor, the airflow in the cotton delivery pipe sends the fiber into the upper cotton storage box, and after being processed by the cotton feeding roller and the opening beater, it arrives The cotton feeding roller and the cotton feeding roller of the carding machine, the suction effect of the fan will remove the impurities and dust in the fibers at the air outlet of the upper and lower cotton storage boxes from the dust exhaust duct, and the air duct pressure of the lower storage box is determined by Pressure sensor measurement and pressure parameter adjustment device control, the humidifier controls the ultrasonic wave after comparing the fiber humidity value at the air outlet of the lower storage box measured by the humidity sensor with the set value by the PLC controller through the A / D converter. The generator humidifies the airflow to ensure fiber humidity and improves carded fiber sliver quality.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a humidifying and static-removing device for a carding machine. Background technique [0002] With the improvement of people's living standards, the demand for clothing and its fabrics has become more diversified and specialized. Chemical fibers such as nylon and polyester are used more and more in military, industrial, outdoor and daily life clothing fabrics. The quality of fiber carding determines the quality of clothing fabrics, but the anti-static problem in the process of chemical fiber carding has always plagued the production of spinning sliver. [0003] At present, the production process of chemical fiber yarn mainly includes antistatic pretreatment, carding, slivering, drawing and yarn forming of fibers. Because chemical fibers have the characteristics of light weight, poor shape retention and fluffiness, low number of crimps and poor retention, resulting in T...

[0002] With the improvement of people's living standards, the demand for clothing and its fabrics has become more diversified and specialized. Chemical fibers such as nylon and polyester are used more and more in military, industrial, outdoor and daily life clothing fabrics. The quality of fiber carding determines the quality of clothing fabrics, but the anti-static problem in the process of chemical fiber carding has always plagued the production of spinning sliver

[0003] At present, the production process of chemical fiber yarn mainly includes antistatic pretreatment, carding, slivering, drawing and yarn forming of fibers. Because chemical fibers have the characteristics of light weight, poor shape retention and fluffiness, low number of crimps and poor retention, resulting in The fiber cohesion is poor, which leads to the problem that the carding machine cannot be directly carded into slivers. Therefore, before sending to the cotton box to open and carding machine for carding, it is necessary to increase the antistatic pretreatment process. Usually, antistatic agents and water mist are used to treat the fibers. , and covered with thatch for 24 hours before rolling. At the same time, antistatic treatment must be carried out on the comb roller. These antistatic pretreatment processes not only increase the production cost, but also prolong the production cycle; The chemical fiber is air-dried and the humidity is reduced during the process of opening the cotton box and preparing to feed the carding machine, which reduces the antistatic ability and easily leads to technical problems that are difficult to form into sliver
