Carding machine bridge mechanism

The role of the carding machine bridge loan institution is to analyze the wool net output by the previous intelligent machine learning, longitudinally study the folding method to form a wool belt with a certain time width and thickness, and transport the data to the next machine in the enterprise to feed the shop. A horizontal stacking is carried out on the upper side, and then it is fed into the cotton feeding roller, which improves the mixing of the raw materials, and improves the evenness and color convergence of the finished yarn. 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. Quantitative B fear of wool, management of work rolls, and silver stripping only improve the blending and quality uniformity of the wool net in the longitudinal direction, and have no effect on the horizontal development; Feeding it again will make our original vertical and horizontal economy fully mix with each other, and achieve the effect of students' all-round stick and uniformity.

As shown in Figure 9-6, the doffer's wool net is peeled off by the chopper and then sent to the pair of rollers 3 and the pair of rollers 4 by the feeding curtain. The card drum 3 is installed on the swing arm 2, which both rotates and swings with the arm. The rotation is designed to transport the wool down, and the swing technology needs to complete the laying of the wool net on the inclined curtain 6. Very simple 4 is installed on the travel frame 5, and due to the push of the swing arm 2, it performs a continuous reciprocating linear upward movement.

A sprocket wheel is installed on the shaft heads of the two reel drums 4, and they are combined with an unfixed chain. Therefore, the pulley 4 also acts as a steering wheel while moving in a linear direction, and its function is to spread the Good Mao A layer compaction. In order to make the chain and sprocket wear more evenly, every time the travel frame chooses to go back and forth, it hits a structure device that uses the pawl to push the ratchet structure, so as to drive the industrial chain to make a small historical displacement. The inclined curtain 6 forms an inclination angle with the doffer axis.

(about 6°-10°) and conveyed to the vertical curtain on the side of the machine at the Chinese speed V2, so after the wool net is folded and the four sides are staggered and listed, it forms a multi-layer space superimposed wool curtain, as shown in Figure 9-7(1); A parallel computing quadrilateral, see Figure 9-7(2). If the speed of the feeding curtain is called, the vertical folded width of the fleece on the slanted curtain is c (generated by the swing arm 2), the sub-speed of the slanted curtain along the doffer axis is v2co, and the width of the fleece is a, then the slanted curtain The number of folded layers m above is: ci in the formula is a component of the folded width of the net. The number of folded layers m is related to the mixing effect of the fibers, generally 7-8 layers.

The speed ratios vi and t can be determined from the values ​​of chuan, a, and ci. As shown in Figure 9-8(1), the wool net is folded longitudinally into a wool belt with a width of b = 400-450mm, which is transferred from the inclined curtain to the vertical curtain 1 on the side of the machine, passes through the bridge curtain 2, and then enters the round-trip curtain 3. After being placed horizontally, the feed curtain 4 is placed on the next machine for processing.

When the feeding curtain moves forward at a constant speed, as shown in Figure 9-8(2), the curtain is placed horizontally at a constant speed v3, so the ribbons are placed along the diagonal line of the feeding curtain and overlap each other. If the grinding is appropriate, the thickness of the feed layer is uniform. Since the lateral placement is a back-and-forth motion, the thickness of the feeding layer should be twice the thickness of the wool belt, that is, the number of folds with wool mesh is 2m.
