It is kept in the bidding operation card, and the drop height is sometimes too high. 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. Special equipment for the textile industry on the winder.
As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field. 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). After doffing, the sliver immediately spit out the sliver and fell to the ground. The mob formed and hung down the edge of the sliver, which seriously affected the quality of the sliver and caused waste to return to the bar. This was a violation of the operation regulations. (1) The doffing is too high, which has great damage to the Tianshi site, the coiler and the sliver can.
In order to reduce the number of discarded templates, any extension to the belt part doffing, the time for mechanical damage becomes large. Therefore, it usually causes abnormal noises and coiling temperatures to rise, some of the zenith plates, and the rigidity of the world, causing the bar to lean, prolapse parts, fall to the floor, barrel life articles disorder, increase Broken, deformed contour bars. More doffing causes difficulties or accidents.
(2) The sliver's fiber material develops disorderly due to strong grinding and inserting, which destroys the normal section structure of the enterprise, increases the free and twisted fibers of a fiber, and causes a large number of neps for students. In addition, during the stretching training process, the fiber cells have great instability and irregularity, resulting in uneven strips (the fibers can be straight and the hook fibers continue to increase). (3) The high dropper is prone to static electricity, dry hair and difficult processing.
In addition, due to grinding with the machine parts, the operation is slow, frustrated, prone to accidental drawing, and thin strips appear, resulting in an increase in the weight of the product and the uneven rate of the process.
