Device for grabbing and removing foreign fibers in textile fibers

Abstract

The invention discloses a device for grabbing and removing foreign fibers in textile fibers. The device comprises a manipulator, a linear module and a servo motor, wherein the manipulator is mounted on a slider of the linear module, the servo motor is mounted at the end of the linear module, and the slider in the linear module drives the manipulator to linearly move by controlling transmission ofa lead screw in the linear module. The manipulator is driven by the slider in the linear module to achieve linear movement, the foreign fibers can be accurately grabbed and removed, the detection rateof visible foreign fibers on a cotton layer reaches 99% or above through actual trial production verification by the applicant, the production efficiency of the follow-up process is greatly improved,the requirement for manual labor is reduced, the foreign fiber content is reduced, and the the purpose of improving the product quality is finally achieved.

Description

【Technical field】 [0001] The invention relates to textile mechanical equipment for cotton processing, in particular to a device capable of detecting and removing foreign fibers in textile fibers. 【Background technique】 [0002] Foreign fiber refers to foreign fiber, which originates from the non-cotton fiber and non-natural cotton fiber mixed with raw cotton during the picking, purchasing and processing of raw cotton, such as chemical fiber, grass, leaf, hair, silk, hemp, plastic film, dyed thread, etc. . [0003] Foreign fibers are not only difficult to remove during the weaving process, but also are broken or carded into shorter, thinner and more fibrous small defects in the impurity removal process. Foreign fibers seriously affect the quality of cotton yarn and cloth, causing uneven dyeing and affecting appearance, which in turn affects the sales of cotton textiles and clothing. At present, with the development of textile technology and the continuous improvement of con...

Problems solved by technology

After investigation, according to the difference in the degree of foreign fiber content in raw cotton or the difference in yarn quality requirements, each person can inspect an average of 1-3 packs of raw cotton per day. A cotton textile enterprise with an average scale of 30,000 spindles requires more than 60 people. The method requires a lot of labor, high cost, foreign fiber detection is completely affected by human factors, and the results of foreign fiber removal are unstable;

[0011] (2) Installing a foreign fiber removal device in the cotton opening and cleaning process is a relatively common method for removing foreign fibers. The foreign fiber machine is usually installed after the last machine in the cotton cleaning process, using photoelectric sensors, ultrasonic principles or optical The principle is to detect the foreign fiber and spray out the cleaning material. However, the cotton has been fully opened at this time, and the foreign fiber in the original cotton has been broken and divided into countless tiny foreign fibers, and the foreign fiber removal rate is greatly limited.

[0012] (3) Install a foreign fiber detection device in the carding and merging process, which is a sensor-shaped foreign fiber detection device, which is installed on the guide frame of the carding machine and drawing frame, and detects when the sliver passes through the transparent conduit. The brightness change will detect the stained sliver, but this method has the same disadvantages as the second method, and some tiny foreign fibers are wrapped inside the sliver, which further reduces the foreign fiber removal rate

[0013] (4) An electronic yarn clearer is installed on the winder, which can detect and monitor the yarn per millimeter, and can also detect and remove small foreign fibers, which can finally meet the market's requirements for the removal rate of foreign fibers, but the efficiency of the winder Therefore, it will be greatly reduced, the number of cuts will be increased, and the production efficiency will even be lower than 50%.

[0014] (5) Cloth face repair is to detect and remove foreign fibers on the finished cloth surface, which is also a manual operation. One method is to manually remove the foreign fibers one by one. The fiber shrinks after melting, and the repair of the cloth surface has high requirements on the eyesight and skills of the workers, and the efficiency is relatively low. Moreover, using the above two methods to remove foreign fibers will cause damage to the cloth surface

[0015] To sum up, it can be seen that there are some defects in the treatment methods of various foreign fibers by the foreign fiber removal technologies of the above different methods, and as the raw cotton production process gradually advances, the difficulty of foreign fiber removal is also increasing. Increase, in order to improve the cleaning effect, the applicant has developed an intelligent device with the function of foreign fiber detection and removal, which can be matched with fiber opening and cleaning equipment such as cotton picking machine, multi-compartment mixing machine, carding machine, etc. In use, it can not only detect foreign fibers in textile fibers, but also remove them thoroughly
