Abstract

The invention relates to a warp feeding device of a warp knitting machine. The warp feeding device comprises a plurality of pan head sets, a plurality of rollers and a frame, the rollers are matched with the pan head sets for use, the frame is used for fixing the pan head sets and the rollers, and the rollers include driving rollers and driven rollers and are driven to work by a speed reducer and a servo motor which cooperate with each other. By the warp feeding device, stability in warp feeding can still be maintained when the warp knitting machine runs at high speed, so that efficiency is improved while fabric quality is guaranteed, and comfortableness, simplicity and convenience in operation are realized.

Description

A kind of warp knitting machine let-off motion

Technical field

The present invention relates to a kind of warp knitting machine let-off motion.

Background technology

Traditional mechanical warp let-off adopts chain belt Moving plate head to rotate the warp let-off, and casing connects warp beam, and each casing is connected sprocket wheel and is connected by chain, and each gearbox body changes by more gear changing the speed that gear ratio regulates velocity of rotation and then change the warp let-off.

This kind of structure is mechanical transmission structure, the parts comprised in structure are numerous, cooperation requirement between each parts will reach very high requirement and accurately could control the process of the warp let-off, this just requires that the processing of part has very high precision, very high requirement is proposed to the processing technology of part, need larger power to overcome the frictional resistance of each parts connecting portion in this mechanism during this kind of mechanical structure running, after machine long time running, the position wearing and tearing easily causing each part to connect, cause the reduction of quality of fit between each part, when total is run, the precision that the warp let-off controls is reduced, affect the effect of the warp let-off.

When machine operates with higher speed, it is very fast that sprocket wheel drives chain to rotate, and too high rotating speed makes sprocket wheel and chain load increase, and can have an impact to the stability of system.

When needing the speed regulating the warp let-off, need the gear in gearbox body to remove to change, complex operation, too much disassembling, assembling and replacing parts can affect the quality of fit of all parts simultaneously, affect warp let-off effect.

The sensitivity of this mechanical warp let-off mode of Chain conveyer is inadequate, there is certain hysteresis quality in the adjustment of warp to this feeding system of warp, this structural configuration is staggered in length and breadth, and the transmission needs oil simultaneously between chain and sprocket wheel lubricates, probably form greasy dirt, affect the attractive in appearance of machine.

Sprocket wheel connects warp beam and directly drives coiled hair to carry out the warp let-off, is difficult to the tension force controlling warp thread.

Summary of the invention

The object of the invention is to: provide a kind of stability that warp knitting machine can be made under the higher speed of service still can to keep the warp let-off for overcoming the above problems, improve efficiency while ensureing fabric quality, operating comfortable easy warp knitting machine let-off motion.

Technical scheme of the present invention is such:

A kind of warp knitting machine let-off motion, comprise some coiled hair groups, framework with the matching used some rollers of described coiled hair group, fixing described coiled hair group and described roller, described roller comprises driving roller roller and passive roller, and described roller coordinates driving work by reductor and servomotor.

Further, described coiled hair group quantity is identical with described roller quantity.

Further, in one end that described driving roller roller and one end of described passive roller, described reductor are arranged, all be connected with gear and be meshed, and be connected with belt wheel in the outside of described gear on described driving roller roller, described reductor is connected by belt with between belt wheel.

Further, described driving roller roller and described passive roller are surrounded by coarse skin.

In sum, owing to adopting technique scheme, the invention has the beneficial effects as follows:

This let-off motion controls the roller warp let-off by computer-controlled servo motor and reductor, only the motor speed numerical value that need change in computer can carry out speed governing to the motor of each shelves, easy to adjust to the speed of the warp let-off, the precision regulated is high, sensitivity is better, reductor drives driving roller roller to rotate by belt transmission simultaneously, yarn after coiled hair gets off through the driving roller roller of roller, yarn divider is entered again after passive roller, its tension force is more steady in the process of the warp let-off, make the warp let-off smooth, ensure that the quality of lopping, this device does not need oil to lubricate simultaneously, substantially greasy dirt can not be formed, system architecture is arranged comparatively neat, make overall machine comparatively attractive in appearance.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is described in further detail.

As shown in Figure 1 and 2, a kind of warp knitting machine let-off motion, comprise some coiled hair groups 1,2,3,4,5,6, its through symmetrically after warp beam being arranged on framework 13, with the corresponding matching used some rollers 7,8,9,10,11,12 of described coiled hair group 1,2,3,4,5,6, it is symmetrically fixed on described framework 13, and the yarn in described coiled hair group 1,2,3,4,5,6 enters tension force and yarn divider through corresponding roller 7,8,9,10,11,12; Described roller 7,8,9,10,11,12 comprises driving roller roller 14 and passive roller 15, and described roller coordinates driving work by reductor 17 and servomotor 16.

Described coiled hair group quantity 1,2,3,4,5,6 is identical with described roller 7,8,9,10,11,12 quantity.

As shown in Figure 3, in one end that one end of described driving roller roller 14 and described passive roller 15, described reductor 17 are arranged, all be connected with gear 18,19 and be meshed, and belt wheel 20 is connected with in the outside of described gear 18,19 on described driving roller roller 14, described reductor 17 is connected by belt with between belt wheel 20.

Described driving roller roller 14 and described passive roller 15 are surrounded by coarse skin.

Yarn walks around passive roller 15 and driving roller 14 after coiled hair group 1,2,3,4,5,6 is got off, yarn is sent into tension force and yarn divider to the frictional force of yarn by the coarse skin on passive roller 15 and driving roller 14, and computer takes the accurate control to thread-feeding amount to by the rotating speed regulating servomotor 16 and reductor 17 and control roller 7,8,9,10,11,12.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
