1. Speed ​​1. Speed ​​of Xinjinlong Increasing the speed of Xinjinlong can improve the carding capacity of the carding machine. 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).

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. As the rotation speed of the cylinder increases, the fiber layer between the cylinder and the cover becomes thinner, and the number of needles for each fiber increases, thereby increasing the carding effect between the cylinder and the cover.

The rotation speed of the cylinder increases, the centrifugal force increases, the impurity and short hair are easy to throw the cladding plate, and the impurity removal rate is high. 2. Doffer speed Doffer speed is an important indicator of production. The full machine width is equal, the lower doffer speed, the feed roller feeding less, no needle load, the reinforcing effect of the carding is beneficial to improve the quality of the cotton web, but the yield is lower.

Therefore, the degree of force should be determined according to the amount, quality and overall production requirements of the doffer sliver. 3. The speed of the licker-in depends on the output of the enterprise, the quality of the raw cotton and the mechanical equipment status of the carding machine. In the case of constant output, the licker-in speed is increased and the reduction rate is whiskered. But continue to increase, reducing the rate at which the beard percentage declines.

Conversely, licker-in constant speed, increased output, increased percentage of whiskers, mainly due to the average of the number of tooth changes experienced per fiber or per gram of fiber. 4. The speed of the cover plate The cover plate has a high speed, and the time for each cover plate to stay in the working area between Xinjinlong and the cover plate is fearful. The number of roots planted on the cover increases, the corresponding cost of cover waste increases, and the impurity removal efficiency can be improved, which is beneficial to the development of cotton web quality. However, due to the low impurity content in the movable cover flower, the amount of effectively utilized fibers increases, which is not conducive to saving cotton.

Therefore, the maximum speed of the cover we generally use is low. 2. Quantitative quantification is determined according to the spinning quantity, carding machine output, quality requirements and production conditions. General quantitative light is beneficial to reduce neps impurities.

However, the high-yield carding machine adopts metal card clothing and Laura leaf cotton, which has a fast loss rate and a small number of cotton webs, which is easy to cause the cotton web to float and increase the number of broken ends. It is better to be slightly heavier. When spinning spun yarn, the quantity should not be too light. At present, the quantitative strip is generally about 16-28g/5m (220-400g/5 yards).

3. The draft ratio of the draft card is determined by the amount of cotton and the amount of sliver. The total drawing of the carding machine is about 100 times. The more spinning times, the smaller the total draft ratio, on the contrary, the less spinning times, the larger the total draft ratio.

Actual drafts are approximately 5% larger than calculated drafts. The other part of the draft is to meet the processing needs, reasonable tension, and to ensure that the valve stem is set well, the draft ratio is relatively small, and generally does not change. Fourth, the parameters of the process and the rules 1. The distance between the feeder and the licker-in The distance between the licker-in and the feeder has a great influence on the carding effect of the entire card machine.

The distance here is large, the length from the starting point of each fiber layer to the holding point is long, and the working length of the cotton bundle or fiber is short, and the part of the fiber layer close to the working surface of the painted cotton board cannot be With a sawtooth carding, the percentage of cotton bundles is significantly increased, and the percentage of short staples is less problematic. As shown in Figure 2, the height of the dusting knife, the angle gauge and the dusting knife thorn located under the chain, its function is to remove broken seeds, leaf debris, sterile and rigid sheets such as cottonseed, and to maintain the thorn fiber.
