Drafting transmission device for roving frame

Abstract

The invention discloses a drafting transmission device for a roving frame. Four shaft seats are arranged on a rack and are used for respectively supporting a first roller head section shaft, a secondroller head section shaft, a third roller head section shaft and a fourth roller head section shaft side by side; the positions of the shaft seats relative to the rack are adjustable, the first rollerhead section shaft, the third roller head section shaft and the fourth roller head section shaft are driven by independent power sources through universal couplings respectively, and the second roller head section shaft is in linkage with the first roller head section shaft through a transmission mechanism and universal couplings. Independent power sources are adopted for transmission of all thedrafting areas; the draft multiple set for spinning is more accurate, and the quality of yarns is better; meanwhile, the roller head sections are connected with the upstream transmission mechanism through universal couplings, so that when the center distance of the rollers needs to be adjusted in the spinning process, only the center distance of the rollers of the drafting part needs to be adjusted, and the drafting transmission device is simple in structure, convenient to adjust and stable and reliable to operate; the draft multiple is more accurate, and yarns with better quality can be obtained.

Description

technical field [0001] The invention relates to a roving frame used in the pre-spinning process flow, in particular to a drafting system in the roving frame. Background technique [0002] The roving frame is the pre-spinning equipment in the textile industry. Its main function is to increase the parallel straightness and separation of the sliver by drawing the sliver supplied by the draw frame through the drawing system, and to improve the sliver by twisting. The strength and compactness of the sliver, and finally the drafted and twisted sliver is spun into roving, which is spun into spun yarn by the spinning machine. [0003] Drafting is one of the four major spinning motions of the roving frame. The function of drawing and thinning the sliver is realized through the speed difference between the rollers of each row. The drafting drive system is the mechanical device that guarantees this movement. [0004] The traditional roving frame drafting drive generally adopts the me...

Problems solved by technology

[0005] Because textile mills need to change the draft ratio and the center distance of each row of rollers when spinning different varieties, the user manufacturer needs to store a lot of replacement gears, and it is also time-consuming to replace the replacement wheels and adjust the center distance of each row of rollers in the headstock Laborious, directly affects the production efficiency of textile operations
