Description

Comb device of carding machine

Technical Field

The utility model belongs to the technical field of the carding machine, a comb device of carding machine is related to.

Background

The carding machine is divided into a woolen carding machine and a worsted carding machine, the woolen carding machine is mainly suitable for carding and processing animal fibers and chemical fibers such as short wool, cashmere, rabbit down and the like, and is suitable for spinning yarns with lower counts.

The carding machine consists of a plurality of action units, a feeding opening unit, a carding unit, a lifting-out unit, a transfer unit, a doffer wool net discharging unit and a strip forming twisting unit. All units have different functions, but are matched with each other, and the function is not the same; the carding unit mainly comprises a cylinder, a doffer, a wool stripping roller, a working roller and the like.

Taking a woolen carding unit as an example, the slitting machine comprises an automatic wool feeder, a pre-carding mechanism, 2-4 sections of carding machines, a gap bridge mechanism, a slitting mechanism and the like. The most prominent of which are carding machines. The automatic wool feeder plays a role in uniform feeding; the pre-carding mechanism is positioned at the feeding end of the unit and plays a role in loosening and pre-carding; the gap bridge mechanism plays a role in uniformly mixing between the front carding machine and the rear carding machine; the splitting mechanism is arranged at the output end of the machine set, divides the wool net into narrow strips and twists the narrow strips into roving.

A pre-carding mechanism and a first section of carding machine in a woolen carding unit. The automatic wool feeder feeds fiber mixture quantitatively, and the slitting machine is introduced into the pre-carding part, slowly fed between the upper feeding roller and the lower feeding roller by the wool feeding curtain and introduced into the wool opening roller. The speed of the opening roller is tens of times greater than that of the feeding roller, and the mixed material can be split. A cleaning roller is arranged below the lower feeding roller and close to the opening roller, and the fibers hung on the lower feeding roller are peeled off and transferred to the opening roller, so that the rollers are prevented from being wound. The opening roller transfers the opened mixed material to the pre-carding part, the slitting machine consists of a pre-carding cylinder (also called a breast cylinder), two opening working rollers and two wool stripping rollers, the opening roller plays a role in carding between the pre-carding cylinder and the working rollers, the opened mixed material is carded into smaller fiber blocks and fiber bundles, and partial mixed material can be changed into single fiber. The function of the hair peeling roller is to peel off the hair layer on the working roller and send the hair layer to the pre-carding cylinder to receive repeated carding action. The fibre layer on the precalcining cylinder is transferred from the transport rollers to the large cylinder of the carding machine. And a fur supporting roller is arranged below the pre-carding cylinder and the conveying roller so as to reduce the fur falling amount of the pre-carding cylinder.

The carding machine consists of a large cylinder, a working roller, a wool stripping roller, a lifting roller, a doffer, a chopper and the like. The large cylinder part of the slitting machine is a main component for finishing carding tasks, 4-6 pairs of working rollers (working rollers) and hair peeling rollers (hair peeling rollers) are arranged around the upper half part of the cylinder, a transport roller is also used as the hair peeling roller of the first working roller, 4-6 carding units are formed, and the carding function is the same as that of the pre-carding part. The carding action on the fiber is gradually fine, and the single fiber content in the fiber layer is more and more. The last carding unit is provided with a lifting roller (also called a wind wheel) and an upper wind-shielding roller and a lower wind-shielding roller. The slitting machine plays a lifting role between the lifting roller and the large cylinder, namely, the needle point of the lifting roller is slightly inserted into the needle space of the cylinder, so that the fibers in the cylinder are lifted to the needle surface, and favorable conditions are created for transferring the fiber layer to the doffer. The upper and lower wind-proof rollers are used to control the air flow of the lift roller, so as to reduce the damage to the hair layer structure. The slitting machine is provided with a doffer in front of the large cylinder, and the arrangement of the needle teeth of the slitting machine and the large cylinder produces carding coagulation. A part of the fibers on the large cylinder is necessarily transferred to the doffer to form a fleece, is stripped by the chopper and conveyed forward, and is fed into the next section of carding machine through the bridge mechanism to be further carded. The number of the sections of the carding machine is determined according to the properties of raw materials and the requirements of spun varieties.

The existing chopping knife is a chopping knife device for a carding machine disclosed in a novel patent (patent number 200920214443.5) for practical use, and the chopping knife device for the carding machine comprises a belt wheel device, a belt connected with the belt wheel device, an eccentric wheel, a connecting shaft and a chopping knife, wherein a transparent protective cover is arranged outside the chopping knife. The belt wheel device drives the belt wheel device through a belt, then drives the eccentric wheel to rotate through the belt wheel device, and then drives the connecting shaft and the chopping knife device arranged on the connecting shaft to reciprocate up and down through the eccentric wheel so as to chop the wools on the doffer. However, the chopping knife device only has one blade, and the fiber layer on the doffer is not completely stripped.
