Design of the drive route of the carding machine

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

The design of the transmission technology route of the carding machine should not only conform to the principle of mechanical transmission and design of the enterprise, and realize the movement development speed (size and direction) required by the carding process for each machine part, but also must be able to ensure the carding. The process has specific environmental requirements such as direct transmission relationship and chain economic relationship between certain construction machinery systems. 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. 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). 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.

There are two common modes of transmission. The design of the above-mentioned transmission technology routes can generally follow the following basic principles: (1) First, the parts with large power consumption are transmitted, so that the power load of the transmission chain at the rear of the transmission route is reduced, and its size can be reduced accordingly. Therefore, usually when designing the transmission route of the carding machine, most of the motors first drive the Xinjinlong with high power consumption.

(2) On the transmission line, use the least transmission chain, reduce the bridge transmission components, reduce the transmission loss, and improve the overall efficiency of the transmission system. In the drive design of the new high-yield carding machine, the motor directly drives the needle cylinder and the needle cylinder with a flat belt (see Figure 2-8). The structure is simple and the transmission efficiency is improved.

(3) Reduced speed transmission can be used as much as possible. When the power of the transmission system is a fixed value, the deceleration transmission can not only reduce the transmission parts and the acting force, but also reduce the size of the parts and improve the stability of the mechanical transmission. For example, the newly developed high-yield carding machine changed the transmission technology route of the stripping roller (Fig. 2-7 (A) during the speed-up process of the doffer to the self-pre-drafting motion mechanism to reduce the speed to drive the stripping roller, and then the feeder The transmission design route of the cotton roller deceleration transmission doffer [Figure 2-7 (B).

wMeet the specific environmental requirements of the production process. In the carding process, it is required that the doffer and the feeding roller company must be able to maintain a certain speed ratio of the enterprise, and the feeding roller must be chained with the doffer. The former is to ensure the main technical parameters of the carding machine through the process - the total pull ratio, the latter is developed to effectively ensure the safety management of the carding machine [after the doffer stops, the feeding roller must immediately stop feeding cotton. (to prevent blocking and rolling), this is the so-called interlocking].

Therefore, although the distance between the doffer and the feeding roller is far, when designing the basic transmission route of the system, a rigid transmission with a reliable mechanical transmission structure should be adopted, so that a direct transmission chain is formed between the two.
