Problems solved by technology

[0003] Under normal driving conditions, the fiber speed on the left and right sides of the cotton web between the upper and lower rollers and the closing of the cluster is greater than the movement speed of the middle fiber, so the fiber draft of the cotton web is larger on both sides and lower in the middle, making the left and right sides The thickness is thinner and the middle is slightly thicker, which may cause the cotton web to break; during the clustering process of the cluster, the high-speed movement of the cotton web will form a high-pressure airflow, which will cause disturbance to the peripheral fibers of the cotton bundle when entering the closing; In addition, The cotton web output from the rollers is subjected to the sharp closing of the bundler and the friction of other auxiliary devices. The cotton web will produce linters, dust, impurities, cotton wax, etc. These substances not only affect the quality of the sliver, but also easily cause Cotton net break
The broken end of the cotton web in the cluster seriously affects the reliability of the carding machine, reduces the quality of the sliver, is not conducive to the improvement of automation, and increases the labor intensity of the operator

Abstract

The invention provides a device and a method for improving the sliver quality in the bundling process of a carding machine. The device for improving the sliver quality in the bundling process of the carding machine comprises a doffer, a stripping roller, a top roll, a bottom roll, a buncher, an upper compression roller and a lower compression roller, wherein the buncher comprises a web gettering cavity; the rear end of the web gettering cavity is connected with a web inlet, and the front end of the web gettering cavity is connected with a closed opening; a gettering opening is formed in the middle part of the web gettering cavity; the gettering opening is provided with a filter screen; the gettering opening is connected with a getter device; the closed opening is formed in a negative pressure cavity; a trumpet opening is formed in the front end of the negative pressure cavity; the buncher is arranged between the top roll and the bottom roll as well as between the upper compression roller and the lower compression roller; the web inlet is positioned on one side close to the top roll and the bottom roll; the trumpet opening is positioned on the other side close to the upper compression roller and the lower compression roller. On one hand, further impurity removal can be carried out on a web, and on the other hand, the change of adsorption force is caused by the change of mesh area, so that drafting is carried out on fibers.

Description

Technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a device and method for optimizing the removal of impurities and lint from the card sliver output by the carding machine and the fiber orientation effect during the bundling process of the carding machine. Background technique [0002] Bundle is a device that gathers the cotton web into bundles in the carding machine. The cotton web is stripped and transferred by the cotton stripping roller on the doffer, enters the upper roller and the lower roller and is output to form a flat-plate-shaped cotton web. After the cotton web fibers pass through the concentrator, they form a columnar cotton bundle with a rectangular section. The cotton net between the upper and lower rolls and the converging end of the cluster is a triangle with a narrow front and a wide rear. The cotton bundle warp coiler is collected in the can for the drawing process. [0003] Under normal driving condit...
