Carding production and supply

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

1. Requirements for the carding process 1. The carding sliver is balanced to the supply and the machine, and sufficient reserves are maintained; 2. According to the requirements of the supply of fixed assets, the supply is in accordance with the number; 3. The sliver of the cylinder height must be consistent, and Make sure to use the rod section; 4. The sliver is well formed, no messy short sliver (pick breakage) is less; (English to Chinese) The sliver is of good quality, not twisted or thinned. 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. 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.

2. Output calculation (A) Theoretical output: the card keeps rotating the theoretical output card device within the unit time, without any loss of production time. The calculation formula is as follows: the speed of the doffer is proportional to the number of teeth of the fast and slow teeth, the theory of carding and the output (kg/set) are proportional to the number of teeth and the number of sliver. The larger the number, the higher the output of the main theoretical research of the carding machine. (2) Actual production output The actual output refers to the output after considering various parking management factors.

Actual yield (kg/unit time) = theoretical yield/production efficiency In order to increase yield, in addition to the introduction of new technology, the speed of sliver doffer is quantitatively defined and limited, mainly in normal production to improve production efficiency, plant productivity, Equipment operating rate utilization device. (3) Production management efficiency Improve production efficiency refers to the percentage of actual output of operating equipment and theoretical research output. Actual Output = Productivity / Theoretical×100% It can be seen from the formula that in order to increase the actual output of the enterprise, we must continuously improve the efficiency of social production management or improve the theoretical output of learning.

The theoretical output is proportional to the speed of the vehicle. For the carding machine, to increase the product output, the doffer speed can be increased, and the number of sliver numbers can be further increased. However, if the doffer speed is too high, the neps and impurities of the cotton net will increase, the quality will decrease, and the sliver number will increase. There will be a certain impact on the processing of the process. Therefore, a more appropriate way to increase the actual output of students is to improve the technical efficiency of the company's production.

There are many factors that affect the efficiency of carding production management, such as stopping the carding machine at 1m head, stopping the machine for maintenance, repairing the broken car, changing the cone, stopping the belt, and stopping multiple machines. Overlap stop, needle copy stop and so on. Therefore, in order to improve the production rate of enterprises, it is necessary to reduce the parking system time for the above analysis as much as possible. (4) The equipment operation rate, but refers to the percentage of the actual operating hours of the equipment stations in the total hours of the equipment stations.

When the total number of units used×The number of actual operations of equipment/instruments with 100% operation rate = the difference between the total number of hours of network equipment and the actual operation and equipment hours is called electronic equipment shutdown, including maintenance and other business shutdowns . Such as large and small flat cars, wiping cars, partial maintenance of needle grinding, repair and replacement of electrical engineering equipment (but not including off-site power outages) and so on. The normal operation rate of equipment is the main economic factor affecting the world's total output. Therefore, these research work should improve the learning efficiency, and strive to put it into operation in advance on the premise of ensuring the quality of management, work and life.

(E) Utilization is the percentage of utilization when using equipment masters relative to the total number of sets of equipment installed. Equipment resource utilization = total hours of network equipment/total hours of installed technical equipment x 100% capacity utilization rate reflects whether the equipment has been installed and makes full use of the installed equipment to maximize the potential of equipment to improve production enterprises one.
