Analysis of the work of the stripping action area of ​​the card

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

The function of the chopper is to completely and perfectly peel off the hair layer taken by the doffer from Xinjinlong to form a hair net. Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field.

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). The stripping action area on the card mainly refers to the action area between the cutter and the doffer hotel. The kitchen knife is a guillotine kitchen knife composed of a swing arm.

The eccentric swing arm keeps the balance at high speed. The chopper arm has blades?? 6-8 dicing saws are serrated. The chopper speed is typically 500 to 1000 cycles per minute.

Doffer the blade tip and cut between 0.25 to 0.3 mm gauge. The chopper swing is about 40mm and the swing position is adjustable. i. Peeling effect of chopper mechanism The shredding procedure shown in Figure 53.

The chopper swings at high speed. For each twist, strip a certain length of wool net from the doffer surface, but the length of the wool net is not equal to the moving distance, it is related to the surface speed of the doffer, the height of the cutter, the effective range, whether the cutter is working properly, and the situation, etc. The reason the chopper strips the wool in the effective stroke, the chopper to the main wool is the impact force.

The chopper is placed at 500-1000 times per minute, so each time the chopper hits the cotton the net effect is a short time. The force of 54, as shown in the figure wool, is shown in the figure. When the chopper reaches a lowest point and starts to return, the students do not peel off the cotton net. The wool net is developed by our own kinetic energy obtained by the chopper and the tension of the traction system of the cotton curtain, which can be automatically removed from the doffer needle surface. Down.

In addition, the chopping knife is also related to the friction and cohesion between the fibers of the wool. Second, the relationship between the speed of the chopper and the doffer When the speed of the doffer is certain, the chopper must choose a correct speed to match. If the chopper speed is too slow, the cotton web will not be peeled off very quickly.

If the cutting speed requirements are too high, in addition to the social necessity of the enterprise, and students are likely to cause carding machine production accidents. Therefore, we must match the speed of the knife and the speed of the doffer. 1. The number of chopper swings is not proportional to the surface speed of Daofu.

2. Dolph speed increases but decreases. 3. Increase the chopper to show off the stroke or increase the effective stroke, the chopper can reduce or increase the number of swings and the speed to increase the productivity or prolong the life of the chopper. 4. Reducing the distance between the chopper and the doffer can appropriately reduce the number of swinging movements of the chopper.

With the rapid development of socialist construction, high output, high quality, low power consumption has become a struggle for the direction of the textile industry. In order to improve the speed of the carding machine, a number of effective measures are adopted for the plant to be used for many reforms to carry out various parts of the chopper, such as improving the chopper position and stroke, improving the mechanical strength, the chopper switch, the minimum shaft of the rolling tank , using chopper step division forging instead of iron common gold, and chopper mechanism for bristles, hair removal and etc. instead of cleaning rollers.
