Carding Process Factors Affect Product Quality

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

In the process of sorting out the production process, we should be highly vigilant about the influence of product quality factors. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. 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). 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.

This is an important task that must be checked and corrected in a timely manner by lower-level managers. 1. Common factors The reserve of semi-finished products and finished products is too large, and it cannot be used for the first time, before and after the workshop, and the products cannot provide balanced convergence. There is a serious mistake. 2. Key factors of each process (1) Blowing process ① Uneven cotton blending, poor lap forming technology (belly swelling, big and small heads), holes and edges, color difference, over-ripe cotton lumps, over-ripening with cords, etc. .

②Dust laying dead rubber, cotton down or with a lot of white cotton. ③The stroke control switch, three automatic lifts, rocking plate and mercury are ineffective as switch protection mechanisms, and the operation of the curtain stutters. Four-comb needle defect 2.5% and above.

5. The pressure of the pressing hook of the carding machine is different, the wallboard is worn, the cotton roller is damaged, the sweet-scented osmanthus is damaged, and the bending weight of the cotton roller is different. (2) Carding process ①The cotton net is obviously uneven, cloud spots, broken edges, holes, many knots, and the cotton balls are brought in and the thickness is uneven. ②Missing hair loss, white flies and more endings.

③The card clothing and sawtooth are seriously affected and have a lot of oil stains. ④ "Carding machine is fast and accurate”Severely dysfunctional. 5. The sliver is simply poorly rotated, tilted, and poorly formed into a loop, the sliver tube is deformed, and there are burrs and flowers.

(3) Combing process ① There are two or more continuous jams on the top of the needle comb, and the Jilin top comb is full of flowers. ② eye, cotton net is significantly out of balance, it is not clear. (4) Drawing process ①The other side of the sliver of the cotton mesh is notable and broken.

②The sliver path is not clean, hanging flowers, and flying flowers can be brought into the sliver at any time. The hanging flowers on the ceiling and the forming technology of the circle strips are not good. Top and bottom rollers beat for heat.

④The top rollers are in oil, there is no real pressing, there is about difference, the pressure of excessive deformation after the abuse of the front and rear column top rollers. ⑤ The drafting gear has bad occlusal relationship, vibration, abnormal noise, missing teeth or serious wear on the top of the teeth. ⑥ The automatic stop device and cleaning device fail.

⑦ The collector does not conform to the standard, defect, beating, or hanging flowers. The silver bar knocked the executioner crooked with flying flowers. (5) Roving process 1. The condition of roving is poor, and the inspection is too strict.

②The uneven hook is obvious, and there is scar formation (usually called shed yarn) 3 yarn diameter hanging flowers. Feihua and Mao Huanhua are mixed with gauze. ④Severely worn round window draft, bad bite, abnormal noise.

⑤ Should be reeled but sleeves, the pressure is not implemented, and the left and right opening of the I-shaped crack are inconsistent. ⑥ Failure of spring compression. Shoulder run abnormally, stutter, deviate, poppet fails, and the straightness of high and low ejection is out of specification. (6) Pressure loss in spinning process (either too light or too heavy) and drum shaking.

② Top roller jumps, has inquiries, heats up, and runs inflexibly. ③ apron deviation, cracks, running is not flexible. ④ The drafting and transmission control systems are improperly engaged in gear engagement, which will seriously affect the wear.

Collector defects, beating, overturning and hanging flowers. ⑤ There is a setback in the rise and fall of the ring plate. ⑥ Yarn hanging slot, loose.

Copper Garden does not complete the ring. 7 The sieve plate is skewed and there are fly thorns, and the loosening is invalid. (7) Groove process ① Leak park stopped me, starved and failed.

②The rocker arm is not flexible. ③ A clearer way to lose the baby, there are serrations.
