Carding machine is the "heart" of cotton spinning equipment, which plays an important role in the process of fiber processing. "If you comb well, you can spin well." This is an experience. Therefore, when the textile industry is developing towards high speed, high yield and high quality, the first problem to be solved in yarn production is carding. Without reliable carding equipment, optimized carding process and scientific maintenance, it is impossible to achieve high-yield and high-quality carding machine.
The use and maintenance of card clothing is an important guarantee to improve the output and quality of carding machine, as well as an important test "base" of equipment factory, which ensures the continuous improvement and improvement of product acquisition. Spinning enterprises should establish a series of management systems, such as the use and maintenance of card clothing, in accordance with their own reality.
01
Establishment of Basic Work System for Card Clothing Maintenance
One
Establishment of Sensitivity Inspection System for Metal Detectors in Cleaning Workshop
Strengthen management, strictly prevent cotton roll (feast cotton) containing metal, hard and flower wrapping, plastic leather, etc., if found, according to cotton roll responsibility number (shift) to implement responsibility; at the same time, strengthen training, improve staff responsibility. Taking the taker-in roll of No. 17 carding truck and the roll of Xilin card cloth in Company A as an example, the autopsy of the truck was analyzed as the result of the introduction of the front wire strip, so the gold fire detection of the clearing line was reformed, and the similar problems were eliminated after enhancing its sensitivity.
Two
Sensitivity Inspection System of Carding Self-stop Device
Every day, the platform contractor inspects the sensitivity of thick roll self-stop, broken head self-stop and return flower self-stop. If it is not sensitive, it should repair it in time and fulfill its responsibility.
Three
Surface cleaning system for card clothing
Every morning shift from 9:00 to 11:00 should clean the surface of Cylinder, Dolph, Cotton Stripping Roller and Transfer Roller, and inspect the operation team leader. At the same time, daily shift maintenance should be carried out on tour to eliminate the phenomenon of inlaying hard objects and winding flowers.
Four
Establishment of "Four Fast and One Precision" Periodic Inspection System for Carding
The equipment inspector of the Ministry of Production and Technology, in conjunction with the heads of each section, regularly inspects the gauges of different parts according to the car protection platform of the Ministry, so as to keep the needle teeth sharp, the gauges accurate and the channels clean. Strict precautions should be taken against the damage of the needle clothing caused by the bad transfer of Douglas.
02
Implementing the management system of card clothing maintenance
One
Responsibilities of Carding Equipment Preservation Post
(a) Establish an extension desk account, record the damage and replacement of card clothing, record the quality index of raw sliver, and form a fluctuation chart to determine the periodic planned maintenance according to the quality index and the use of card clothing; in production, we often use condition-based maintenance to replace planned maintenance.
B) Do a good job of card clothing maintenance. The contractor maintains the contracted platform and clothing. At the same time, each shift of locomotives should clean the clothing in place to ensure that the clothing is in good condition.
C) Establish the necessary system of grinding and copying needles. Because of the current development of clothing toward low, small, sharp, shallow, dense direction, coupled with the short life of domestic clothing, some enterprises do not think it necessary to grind needles. In fact, a long time without needle grinding will lead to excessive wear and tear of the card clothing and difficult to control neps, and eventually have to replace the card clothing.
D) The effect of wrapping and maintenance of card clothing by using factory is very important for using new metal card clothing well, prolonging its service life and giving full play to its technological performance. It should be strictly carried out according to the requirements of card clothing wrapping standard.
E) Check the implementation of "four speeds and one standard" monthly, and make relevant records. Carding machine's main spacing must be installed according to the technological requirements, reasonable distribution of carding speed and output, and strict technological discipline of boarding.
F) The production technology department and the workshop equipment hold a equipment Symposium once a month to analyze and prevent the damage of the card clothing in each branch factory, so as to ensure that the service cycle of the card clothing is reasonable and the machine clothing is in good condition.
G) Establish a monthly non-damage reward system for machine tool Contractors'clothing and fully mobilize the enthusiasm of workers.
Two
Responsibilities of Carding Equipment Supervisor
(a) In case of injury accident of card clothing, we should abide by the principle of "three must not let go". We should make sure that the platform is packed, the responsibility is assumed, and the problem is managed. We should constantly sum up the lessons and accumulate experience.
B) Hold a monthly special meeting on the analysis and prevention of card clothing damage in view of equipment conditions, implement responsibilities, improve measures, and rationally distribute the dual management scope between operation and equipment.
C) Regularly organize relevant technical personnel to inspect the maintenance and implementation of card clothing, and incorporate good advice and good policies for card clothing maintenance in the light of the platform of the Games, quality month and rationalization suggestions.
D) Check the maintenance status of three shifts of clothing in time to ensure that the clothing is maintained in place for 24 hours.
E) Rationally configure the card clothing, do well the matching of the card clothing, ensure the improvement of product quality and prolong the service life of the card clothing.
