With a vacuum point carding machine, you must choose among many thread ends that the flies escape. 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). 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.
Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame. Figure 2-26 is not equipped with a suction device before the card cotton dust overflow condition.
Figure 1 is doffing at the highest dust content at the large cotton dust discharge port on the front cover. Other cotton webs and the top of the stripper roll 2, pressure roll 3 large, flare 4, and large brushes on the front cover panel 5, rear cover plate 6 and the rear area of the coiler plate, feed After peeling of the roll and licker-in in cover 7. The spill case is lint and closed, allowing for easy, but less uniform lateral suction.
The main purpose here is to suck the vehicle to avoid falling into the white belly. 2. Doffer dust hood has two types: sandwich type and long mouth type, as shown in Figure 2-28. Sandwich hoods have a large vacuuming area and are mostly used for doffer hoods and stripping rollers.
Because the airflow driven by the high-speed rotary motion of Xinjinlong is blocked from the distance point of Xinjinlong doffer, a positive pressure system overflow is formed, which is sprayed to the side and front of the machine and emits cotton dust (see Figure 2-26-1) . If you use a long mouth to reach the Xinjin Longdaofu think triangle area for vacuuming, the effect can be better. 3. Dust funnel Figure 2-29 shows the dust spot on the rear belly of the carding machine, which is directly connected with the branch air duct and the branch air duct, heated by the fan, and blows the falling objects from the front and middle car belly to the rear car belly.
The above problems are that enterprises generally have high-yield carding machines on“three suctions”in the form of a hood. The installation under the upper chopper requires a slotted dust cover as the suction port of the movable cover, which is“four suctions”. Each suction point carding machine is generally continuous suction, but it can also be used for intermittent suction in the belly of the car, saving the advantages of air volume, power consumption and building area.
