The plugging of the carding machine must be inspected according to a certain route, and the work of drafting, yarn retention, piecing, cleaning, checking equipment, and preventing defects must be organically combined and carried out crosswise, so as to master the production rules and realize the initiative. , planning and flexibility. The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. Grinder A spinning machine that turns fiber strands into rovings.
The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process.
The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). (1) The tour route adopts a one-way reciprocating tour method, from left to right and from right to left. Pagoda-style yarn change, change intelligence and piecing by energy, check the quality of simple yarn, mainly focus on piecing when going (going), and focus on cleaning and inspection (checking defects, checking machines).
During the tour, the following three aspects should be combined. 1. Combination of anti-touring routes, capture yarn defects, and strengthen quality control. Discover steps, mechanical, artificial defects in time.
2. Combined with the tour to do a good job in the cleaning management of the yarn channel. 3. Combine roving and yarn breakage with reasonable process to ensure uniform size of bobbin axis and opening. (2) Use your eyes to deal with broken heads.
Especially at present, most of the carding machines are equipped with electronic cards, and the crushing head rate is relatively high. Reasonable processing of the crushing heads according to the operating conditions is conducive to increasing the output. When traveling back to use the eyes sensibly. After every pick look to the left and right 10. When looking to the right to take the yarn, then look to the left after a good start to see if there has been beheading, and if promptly treat the beheading.
2. To master the three first and three after treatment is to cut off the head. (1) Easy-Hard - Easy head first, followed by hard floor for head. Reel Side Rescue For example, when the yarn is turned on, it should be held by the cantilever, generally easy to pick up the first contact break, then return to the retainer ring, turn on the broken yarn.
(2) Before, after, before and after - first connect the decapitation in front of the development of the tour guide direction, and then connect the decapitation. If there are more than two in an important direction, it is broken. The front and the direction should be close to the back, and the western management direction should be far and near to keep the cop slanted. Quality control should be based on prevention, combined with prevention and treatment.
Street vehicle staff must combine inspection and supervision, use clean vision and tactile sense reasonably in the operation, and correctly grasp the“prevention”,“catch”,“an examination”The Plaza Station Essentials. 1. Prevent artificially set defects, make“Three attention”(1) When a single technical operation is carried out for joint, focus on management thinking, and always pay attention to whether the rotation of the tension plate can be normal, to prevent the generation of small braids, to prevent the return of silk and flying flowers from attaching to the bobbin, and to prevent students from piling their heads. (2) For cleaning, the transparent tape should pay attention to the part of the yarn passage, and promptly remove the yarn piece, the yarn tension disc, fly, and go to the box to prevent damage caused.
(3) When taking the yarn, finding the head, and doffing the package, it is necessary to pay attention to preventing and catching the defects and package defects of the upper process at any time. 2. Processing order defects, the point is reached“Three gold and three delicious”(1) Check whether the number of bags is wrong, and check whether the empty bag is correct for customs clearance. (2) Look at the slanting shape of the cop yarn when it is touring in sections, and find that the cop yarn consumes a lot of time and cannot be too long or too short.
Is it easy to make mistakes in checking the yarn number. (3) When piecing and doffing yarn, look at the yarn defect in operation, and check for a defect in the process such as strong and weak twist, multiple missing strands, slub, oily yarn, wrong special number and wrong tube.
