Description
Technical field
The utility model discloses a kind of multi-bar jacquard warp knitting machine ground comb electronic letting-off device, belong to technical field of knitting machinery.
Background technology
The multi-bar jacquard warp knitting machine is the yarn that a group or several groups is arranged in parallel, and on all working pin of warp-wise feeding machine, lopping simultaneously forms a kind of machine of knitted fabric.The multi-bar jacquard warp knitting machine is mainly used in produces mesh class jacquard fabric.The multi-bar jacquard warp knitting machine of domestic production at present, its ground comb let-off motion adopts the mechanical type FAG warp let-off mostly, easily causes tangible stopping line when driving stopping, and hand-turning is quite difficult through axle during last machine, can not adapt to high-speed production.
The utility model content
In order to address the above problem, the utility model provides a kind of obvious stopping line, easy to operate and can adapt to the multi-bar jacquard warp knitting machine ground comb electronic letting-off device of high-speed production that do not have.
To achieve these goals, the technical scheme that the utility model adopted is:
Comb electronic letting-off device in a kind of multi-bar jacquard warp knitting machine ground comprises that the lower surface is installed in the right side on the warp let-off base plate through bracing strut, and is installed in reduction box on the warp let-off base plate by the deceleration block; Wherein, the right side is equipped with once the right spindle nose of axle by first needle bearing, second needle bearing in bracing strut, passes warp let-off base plate through the bottom of the right spindle nose of axle and extends outward, and on this bottom first synchronous pulley is installed; Second synchronous pulley that is connected by synchronous band with first synchronous pulley is installed on the output shaft of reduction box; The input of reduction box is connected with the AC servomotor, the control system control that the AC servomotor is made up of frequency converter, PLC controller.
Described reduction box is the transmission of worm and gear one-level, and output and input speed ratio are 1: 60.
Gearratio between described first synchronous pulley and second synchronous pulley is 3: 1.
The specification of described first synchronous pulley is 90 teeth, and the specification of second synchronous pulley is 30 teeth.
The power of described AC servomotor is 0.75KW, and rotating speed is 3000rpm.
After the utility model adopts such scheme, its beneficial effect is: do not have obvious stopping line, to comb the warp let-off effective, warp thread from the dishful head to the blank panel head, constantly regulate warp run-in automatically, remain constant-tension, guarantee multi-bar jacquard warp knitting machine high speed, steady production lace fabric, and the utility model light in structure coincidence reason, easy and simple to handle, visual strong, noise is low.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model front scheme of installation.
The specific embodiment
As shown in Figure 1 and Figure 2, comb electronic letting-off device in the utility model multi-bar jacquard warp knitting machine ground comprises that the lower surface is installed in the right side on the warp let-off base plate 5 through bracing strut 3, and is installed in reduction box 8 on the warp let-off base plate 5 by deceleration block 11.Wherein, the right side is equipped with once the right spindle nose 1 of axle by first needle bearing 2, second needle bearing 4 in bracing strut 3, passes warp let-off base plate 5 through the bottom 14 of the right spindle nose 1 of axle and extends outward, and on this bottom 14 first synchronous pulley 6 is installed.Be equipped with on the output shaft of reduction box 8 with first synchronous pulley 6 by synchronously with 10 second synchronous pulleys 9 that are connected.The input of reduction box 8 is connected with AC servomotor 7, the control system control that AC servomotor 7 is made up of frequency converter 12, PLC controller 13.
As further setting of the present utility model, reduction box 8 is the transmission of worm and gear one-level, and output and input speed ratio are 1: 60.Gearratio between first synchronous pulley 6 and second synchronous pulley 9 is 3: 1, and preferred specification is first synchronous pulley 6 of 90 teeth, and specification is second synchronous pulley 9 of 30 teeth.The power of AC servomotor 7 is 0.75KW, and rotating speed is 3000rpm.
Operation principle of the present utility model is:
The programmable control system of being formed by frequency converter 12, PLC controller 13, the turning to of control AC servomotor 7, rotating speed, second synchronous pulley 9 that the rotation of AC servomotor 7 drives on the reduction box 8 again rotates, and the rotation of second synchronous pulley 9 is again by being with 10 to drive 6 rotations of first synchronous pulley synchronously, thereby the final rotation that realizes through the right spindle nose 1 of axle forms the ground comb warp let-off.
The utility model multi-bar jacquard warp knitting machine ground comb electronic letting-off device can be realized the higher speed of a motor vehicle, and the change warp run-in is convenient, rapid.Control is separately adopted in the various places comb warp let-off, has reduced friction and energy loss, has reduced noise, has improved operation comfort.
The foregoing description only is used to the inventive concept of the present utility model of explaining, but not to the qualification of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
