Main transmission device of double-needle warp knitting machine

Abstract

To realize synchronous opposite rotation of a pair of main shafts of a double-needle warp knitted machine, the invention relates to a main driving device of the double-needle warp knitted machine, comprising: a first main shaft, a second main shaft, an electric motor, a small belt pulley fixed on an output shaft of the electric motor, a large belt pulley fixed on a front end head of the first main shaft, a first synchronous belt pulley, a second synchronous belt pulley, a guide shaft fixing pedestal, an upper guide wheel, a lower guide wheel, an upper guide shaft, a lower guide shaft and a double-surface synchronous belt; the first synchronous belt pulley is fixed on the first main shaft, the second synchronous belt pulley is fixed on the second main shaft; the upper guide wheel is supported on the upper guide shaft through a bearing, and a top point at the upper end of the upper guide wheel is higher than that at the upper end of the second synchronous belt pulley; the double-surface synchronous belt is pressed onto the second synchronous belt pulley with an outer tooth belt thereof facing downwards, and the outer tooth belt is meshed with the second synchronous belt pulley; and the double-surface synchronous belt is provided in manner of tension between the first synchronous belt pulley, the upper guide wheel, the lower guide wheel and the second synchronous belt pulley.

Description

technical field [0001] The invention relates to a main transmission device of a double-needle warp knitting machine. Background technique [0002] At present, there are many types of warp knitting machines, and their main mechanisms include: [0003] 1) Knitting mechanism, which is used to form warp yarns into loops that are intertwined with each other to form warp knitted fabrics. The main knitting parts are knitting needles, sinkers and guide needles. [0004] 2) The warp let-off mechanism is used to supply the yarn on the warp beam to the loop forming mechanism for weaving. There are usually two types of warp let-off mechanisms: one is the positive warp let-off mechanism that actively conveys warp yarns through mechanical and electrical transmission devices; the other is the negative warp let-off mechanism that pulls the warp shaft to unwind by the warp tension generated during weaving. . [0005] 3) The bar transverse movement mechanism is a mechanism for controlling...

Problems solved by technology

[0011] The weak point of above-mentioned prior art is: when warp knitting machine works normally, adopt main transmission motor to provide power; and inconvenient to use

[0014] The above-mentioned prior art discloses a scheme of controlling the main motor through a frequency converter, so that the slow motor can be omitted, but it still cannot solve the problem of reliable rotation of a pair of main shafts in a double-needle warp knitting machine synchronously and in opposite directions.
