Main carding mechanism of interlaced fabric carding machine

Abstract

A main carding mechanism of non-woven cloth carding machine, which belongs to the field of non-woven machinery technology, comprises main cotton carding drums arranged on wall plates on two corresponding sides of a frame, a plurality of carding unit groups consisting of a working roller and a cotton stripping roller and similarly arranged on the wall plates of the two corresponding sides of the frame, and a web making roller and a stripping roller arranged on two corresponding sides of the frame rotatablely at both ends, wherein a transfer roller and the stripping roller are independently rotatablely arranged on the frame. The main carding mechanism is characterized in that a high-speed cotton stripping roller matched with the main cotton carding drums is arranged on the frame at a position substantially above the space between the main cotton carding drums and the web making roller and corresponds to the length directions of the main cotton carding drums and the web making roller. The main carding mechanism has the advantages that the fiber on the main cotton carding drums are completely transferred to the web making roller to make the weights of thin cotton webs reaching a transfer curtain consistent with each other, so that the production can be carried out continuously without periodically stopping machine to clean the main cotton carding drums.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a main carding mechanism of a carding machine. Background technique [0002] The carding machine for nonwovens includes a feeding box (commonly known as a wool box), a pre-carding mechanism, a main carding mechanism and a web forming mechanism. The main carding mechanism is responsible for pre-carding the pre-carding mechanism and transferring it Then the fibers are fully combed, and the fully combed fibers are transferred to the main carding cylinder, which is customarily called the big cylinder or the main cylinder, and then supplied to the web forming roller of the web forming mechanism (referred to as dove in the industry) to form a web. , and then stripped by the stripping roller to the output curtain. [0003] The nonwoven fabric carding machine of the above structure can be interpreted through the Chinese patent authorization announcement number CN...

AI Technical Summary

Problems solved by technology

[0005] The main carding mechanism of the above structure can play a good role in the carding of short fibers such as polyester, polypropylene and / or polyester cotton, but for carding of glass fibers, there will be a phenomenon of "acclimatization", that is, the phenomenon of raw materials not suitable , because the glass fiber short fiber has a large proportion and the fiber has no crimp. During the carding process, the fiber will sink and float on the bottom of the card clothing of the main carding cylinder, and it is difficult to completely transfer to the web forming roll, so that the condensed on the web forming roll The grammage of the formed thin mesh fiber web cannot be controlled; and, the main carding cylinder cannot work continuously for a long time, and it is usually necessary to clean the main carding cylinder in about 3-5 hours, so that the unused carding cylinder will not be transferred to the web forming roller. The glass fiber still floating on the bottom of the card clothing of the main carding cylinder is removed, and if it is not removed in time, it will cause damage to the card clothing and even damage the equipment

Therefore, the main carding machine of the nonwoven fabric carding machine currently used in the industry cannot cope with the carding material of glass fiber or short fibers containing glass fiber. However, for the production of temperature-resistant nonwoven fabric filter materials and thermal insulation, Thermal insulation or heat-resistant nonwoven products inevitably use glass fiber
