Effective Measures To Solve Adhesion, Entangling, Blocking And Hanging In Combing Process

Temperature and humidity management

Strengthen the management of air conditioning, ensure the reasonable temperature and humidity of workshop, and reduce the fluctuation of temperature and humidity in workshop. The cooling and dehumidifying capacity of air conditioning in summer is very high, which brings great difficulty to air conditioning management. At the same time, in order to adjust the temperature and humidity to ideal condition in high temperature and humidity season, the running cost of air-conditioning is also very high. Therefore, in the high temperature and high humidity season, the temperature and humidity of the workshop are maintained at a relatively high position under the premise of ensuring smooth production. Therefore, in the high temperature and humidity season, if the temperature and humidity control is bad, frequent or large fluctuations will seriously affect the stability of the workshop's life status and product quality.

Two. Do well in the drafting area.

While doing well in temperature and humidity control, it is one of the effective measures to reduce the sticking, wrapping, blocking and hanging. It is necessary to avoid the grease pollution in the drafting area. During the inspection period, the adhesion of roller, roller, whisker, cotton wax, oil or sugar should be regarded as timely. The cleaning work of combing process is as follows:

One

The combing and wiping car implements the warm and hot water cleaning method, namely, cleaning with hot wet cloth, wiping the upper and lower lip of the nipper, separating the roller, stretching roller and all cotton bar passages and noil channels, clearing the sticky sticky objects and the applique, which are adhered to the triangular airflow plate, drying with soft dry cloth and polishing with chalk ash.

Two

When you wipe the car, comb the top comb into the container of warm water for about 5 minutes. Use the plate brush to clean the sticky substance impacted between the top comb needle teeth, clean it and dry it with compressed air pipe.

Three

The equipment maintenance personnel clean the responsible machine platform with warm wet cloth every day, wipe the upper and lower lip of the nipper, detaching roller, draft roller, cotton bar passageway of all cotton bar passageways, and then use chalk ash to polish.

Four

The maintenance personnel should be added once a week to clean the top comb with warm water. The combing truck will add the work of the upper and lower lip of the cleaning pliers and the needle plate on the top comb.

Three, ensure good condition of carding equipment.

It ensures the good operation state of carding equipment, ensures the stability of yarn quality and improves production efficiency. Combing carding equipment should be smooth, no damage and no applique. The density of the carding area, the rack density and the combing point should be optimized, so as to minimize the phenomenon of combed cotton web breaking, breaking and breaking. Specific measures include:

One

The density of Xilin rack is optimized. In order to maximize the carding efficiency of Xilin, it is necessary to reasonably deploy and appropriately increase the rack density in the limited carding interval, and strengthen the puncture, grabbing, loosening and combing in the front area. At the same time, it is also necessary to avoid the overtightness of the rack in the front area, resulting in the phenomenon that the comber has broken holes in the cotton web at high speed.

Two

Reasonable use of brush reverse technology. If used properly, the imported brush can be used for 6~7 years, and domestic brush can be used for 4~5 years. When the conventional treatment of Xilin inlaid technology measures does not work, do not haste to adjust the depth of the brush palm into the cylinder (because this will easily aggravate the damage of brush hair and shorten the service life of the brush). The brush should be used in reverse direction. This is because most of the domestic brush is made of domestic brush, and the domestic wool brush has relatively poor elasticity. The brown hair of the brush will fall down along the direction of the carding. At this time, the brown hair of the brush is in the forward direction with the needle teeth of Xilin, which greatly reduces the cleaning efficiency of Xilin. If the brush is reversed at the moment, the brown hair of the brush can be in reverse state with the needle teeth of the cylinder, so that the tip of the palm can have good elasticity, and the proper control of the depth of the brush insertion into the needle tooth of the cylinder is beneficial to the inlaying of the Xilin toothed sheet. After a period of time, the brush is reversed. The cleaning effect is equivalent to increasing the depth of the brush into the cylinder by 1 mm. The reverse cycle of brush is generally controlled for 3 months, and the effect is better.

Three

Adjust the brush speed reasonably. Brush speed directly affects the cleanliness of Xilin and the state of cylinder fiber. With the increase of the speed of combing locomotives, the technical concept that the surface speed ratio of the traditional cylinder and brush is controlled between 1:5.8 and 6.8 can not fully meet the actual needs. Through the test, the speed of the comber brush is 1200 r/min, and the cleaning effect of Xilin is better.

Four. Prolong the service life of Xilin rack effectively.

Under the premise of guaranteeing the carding quality, the service life of Xilin rack can be extended as far as possible, so as to effectively reduce the phenomenon of Xilin hanging flowers.

One

The conventional first, second sets of Xilin rack specifications are the same, and the rack skew pieces are beige. In the first group, the first row of Xilin rack teeth are easy to damage. When the use time of the cylinder is about eight months, first, second groups of Xilin rack are exchanged for use. This can effectively improve the carding quality, keep the cylinder tooth surface clean, and extend the service life of the cylinder rack.

Two

In the uniform replacement of Xilin rack, some relatively good Sn rack (rack tooth surface damage, non applique and dirt free) can be selected and retained, so that the SN rack with embedded flower can be replaced at any time to ensure that the cylinder tooth surface is clean, the machine material consumption is reduced, and the service life of Xilin rack is extended.

Three

By properly increasing the density of the Xilin rack in the front and back regions, the three point gauge (front, middle and back area) of the cylinder should be strictly controlled, and the carding spacing of the cylinder is small. The neps can be reduced, but the damage of the fiber and the damage of the cylinder will be reduced if the carding distance is too small. Therefore, the determination of cylinder carding spacing should be optimized according to the density configuration of Xilin rack, the volume of small rolls and the quality requirements of customers.

Four

The process design of the combing preparation process should give priority to the fiber's straightness, parallelism and separation, so as to ensure that the small coil is unbonded during the unwinding process, so as to save cotton, reduce the damage of the cylinder rack, and improve the service life of the cylinder rack.

The above technical measures can greatly relieve the phenomenon of sticking, wrapping, blocking and hanging in combing process in high temperature and high humidity season.
