(1) Reasonably adjust the parameters such as the forward timing of the separation roller, the timing of closing the nipper, and the positioning of the cylinder, adjust the pressure of the separation rubber roller and the draft rubber roller, and rationally configure the width of the cotton collector between the separation rollers (new combing machine) The width of this collector can be adjusted) to improve the quality of separation and joining. If the length of the fiber and the length of the feeder are relatively long, the timing of the forwarding of the separation roller should be properly early, especially when advancing to the cotton. However, the separation roller should be taken into account. The interference of the rear cylinder teeth of the cylinder to the tail end of the cotton net poured into the machine after the early reversal. From the perspective of improving the quality of the separation and joining and reducing the unevenness of the strip, the timing of the closing of the clamp plate should not be too early, otherwise the opening will be far, affecting the clump The head is straightened, which affects the quality of the disengagement. However, it should be noted that the timing of the closing of the jaws will determine the reliability of the grip of the jaws on the cotton layer when the cylinder starts to comb. It is necessary to handle the relationship between these mutually restrictive and influencing factors.
(2) The drafting process of correctly configuring the drafting mechanism. The unevenness of the sliver after drafting is generally large. If the drafting configuration is not correct, the sliver will be further deteriorated. Parameters such as sliver quantification, fiber length, drafting capacity in the subsequent process, etc. Correctly configure the draft multiple, roller gauge and pressure of the drafting mechanism. On the new domestic combing machine, the drafting mechanism uses a relatively large comb The amount of sliver (smaller draft multiple) is helpful to ensure the sliver of the combed sliver, and can also reduce the speed of the sliver mechanism, which can be used by other models for reference. The rear draft of the FA266 comber is designed to be adjustable , Increase the flexibility of adjustment, help to rationally adjust the process parameters, improve the evenness of the strips.
(3) Reasonably control the tension drafting of each part. Since the combing strip is formed by the joints of the whiskers, and the parallel stretch of the fibers is high, the cohesion between the fibers is poor, and it is easy to produce unexpected elongation, so, In the case of no sliver wrinkling, the tension draft should be as small as possible. After the drafting mechanism is drafted, the tension draft is preferably close to 1.
(4) Keep the cylinder and top comb mechanically in good condition, without intarsia, separate rubber rollers, drafting rubber rollers and pressure rollers, etc. The surface is smooth, flexible rotation, and the passage of the sliver is smooth, preventing damage to the structure and production Unexpectedly elongated.
