[ technical field ] A method for producing a semiconductor device

The invention relates to textile machinery equipment for cotton processing, in particular to a device capable of detecting and removing foreign fibers in textile fibers.

[ background of the invention ]

Foreign fiber is foreign fiber, which is derived from non-cotton fiber and non-natural color cotton fiber mixed into raw cotton during picking, purchasing and processing of raw cotton, such as chemical fiber, grass, leaf, hair, silk, hemp, plastic film, dyeing line, etc.

Foreign fibers are not only difficult to remove during the spinning process, but also are stretch broken or carded into shorter, finer and more fibrous fine defects during the trash removal process. The foreign fiber seriously affects the quality of cotton yarn and cloth, leads to uneven dyeing, affects the appearance and further affects the sale of cotton textiles and clothes. Currently, with the development of textile technology and the continuous improvement of consumption level, the requirement of consumers for different fibers in cotton textiles is higher and higher, and the different fibers are a focus of attention in the textile industry.

At present, the method for removing the foreign fibers mainly comprises five methods:

firstly, manually picking and removing foreign fibers;

secondly, installing a foreign fiber detecting and removing device in the opening and picking process;

thirdly, a foreign fiber detecting and removing device is installed in the cotton carding and combining process;

fourthly, the function of the electronic yarn clearer is expanded on the bobbin winder;

fifthly, performing cloth cover repair in the cloth cover inspection link of the fabric.

(1) The manual picking of the foreign fibers is generally arranged before raw cotton is put into production, the detection of the foreign fibers is mainly carried out by a manual eye detection method, and then the foreign fibers are manually picked. According to the investigation, 1-3 packages of raw cotton can be averagely detected by each person every day and a cotton textile enterprise with the average scale of 30000 spindles can detect the raw cotton with different fiber degrees or different yarn quality requirements, the labor is required to be more than 60 persons, the method has the advantages of more labor and high cost, the different fiber detection is completely influenced by human factors, and the different fiber removal result is unstable;

(2) the installation of a foreign fiber removing device in the opening and picking process is a common method for removing foreign fibers, a foreign fiber machine is usually installed behind the last machine table in the opening and picking process, a photoelectric sensor, an ultrasonic principle or an optical principle is adopted to detect foreign fibers, and removed objects are sprayed out. (3) The different fiber detection device is arranged in the carding and combining process, is a sensor type different fiber detection device, is arranged on a guide frame of a carding machine and a drawing frame, detects out the colored and dirty cotton sliver by detecting the brightness change of the cotton sliver passing through a transparent guide tube, but the method and the second method have the same defects, and other tiny different fibers are wrapped in the cotton sliver, so that the different fiber removal rate is reduced.

(4) The electronic yarn clearer is arranged on the bobbin winder, so that each millimeter of yarn can be detected and monitored, micro foreign fibers can be detected and removed, and finally the requirement of the market on foreign fiber removal rate can be met, but the efficiency of the bobbin winder is greatly reduced, the cutting frequency is increased, and the production efficiency is even lower than 50%.

(5) The cloth cover picking and repairing is to detect and remove the foreign fiber on the finished cloth cover, and also belongs to manual operation, one method is to manually remove the foreign fiber one by one, the other method is to use a blower to heat melt the foreign fiber, so that the foreign fiber shrinks after being melted, the cloth cover picking and repairing has higher requirements on the vision and the skill of workers, the efficiency is lower, and the foreign fiber removing by adopting the two methods can damage the cloth cover.

In summary, it can be seen that the different fiber clearing techniques of the above different methods have some defects in various different fiber processing modes, and as the raw cotton production process is gradually advanced backwards, the difficulty in clearing the different fibers is also increasing, and in order to improve the clearing effect, the applicant has developed an intelligent device with a function of detecting and removing the different fibers, which can be used in cooperation with fiber opening and clearing processing equipment such as a plucker, a multi-bin cotton mixer, a cotton carding machine, and the like, and can not only detect the different fibers in the textile fibers, but also can more thoroughly grab and remove the different fibers.
