Dynamic balance tension traction mechanism and knitting machine with same

Abstract

The invention relates to a dynamic balance tension traction mechanism and a knitting machine with the same. The dynamic balance tension traction mechanism comprises a rotating shaft, a tension adjusting mechanism, a plurality of groups of transmission sheets and winding wheels, wherein the transmission sheets are in one-to-one correspondence, the transmission sheets are round sheets, shaft holes are coaxially formed in the middle parts of the transmission sheets, and the plurality of groups of transmission sheets are arranged on the rotating shaft in a sleeving mode separately; the tension adjusting mechanism is installed on the rotating shaft, connected with the transmission sheets and used for adjusting the balance of the transmission sheets and the rotating shaft; assembling holes are coaxially formed in the middles of the winding wheels and coaxially arranged outside the corresponding transmission sheets in a sleeving mode; elastic pieces are connected between the winding wheels and the corresponding transmission sheets, and when the winding wheels and the corresponding transmission sheets rotate relatively, the elastic pieces perform synchronous compression; and hooking and pulling teeth are arranged on the outer edge of the winding wheels in the circumferential direction of the winding wheels at intervals. The dynamic balance tension traction mechanism has the advantages that the structural design is simple, parts are easy to replace, the traction force can be automatically adjusted according to different coil vertical-direction lengths, the traction tension acting on each coil is stable, uniform and consistent in the vertical direction, and a good tension adjusting effect is achieved.

Description

technical field [0001] The invention relates to the textile field, in particular to a dynamic balance tension pulling mechanism and a knitting machine with the same. Background technique [0002] The pulling and winding mechanism commonly used in weft knitting machines is to fix one end of the fabric on the pulling roller, apply a certain pulling tension to the fabric through the holding of the pulling roller and the rotation of the roller, and then wind it into a certain form and capacity. of rolls. During this process, with the rotation of the pulling roller, all the coil wales will be subjected to the same pulling tension, which causes some coils with different lengths to be pulled larger or smaller than their own required tension. force, thereby forming a coil that becomes larger or smaller. [0003] According to the different driving methods of the pulling roller, the pulling and winding mechanism of the circular weft machine has three types: mechanical continuous pul...

Problems solved by technology

[0007] In summary, these pulling and winding mechanisms use different principles to pull and wind knitted fabrics into packages, but during the pulling process no matter What is the height of each coil, and each column of coils is subjected to equal pulling tension, and the pulling roller cannot treat each coil in a fine-grained manner, resulting in the failure of the formed fabric to achieve the desired effect, and the knitted fabric presents a bow-shaped bending deformation phenomenon in the coil row
