Abstract
The invention discloses a high-efficient and low-cost draw-off mechanism for a computerized flat knitting machine. The draw-off mechanism is composed of a main draw-off mechanism and an accessory draw-off mechanism. A main draw-off roller is composed of 24 cloth rolling wheels divided into a front group and a rear group; an accessory draw-off roller 6 is a circle-arc tooth-shaped control steel bar. The traditional draw-off modes of the main draw-off roller and the accessory draw-off roller are all implemented by carrying out the draw-off action on knitted fabrics through the mutual meshing rotation of the front group of draw-off rollers and the rear group of draw-off rollers, and the draw-off mechanism disclosed by the invention draws off the knitted fabrics through the mutual friction between draw-off belt fasteners on the front and rear groups of draw-off rollers. The draw-off operations of the draw-off belt fasteners are driven by a cloth roller 14 through frictional forces. Because the diameter of a cloth pressing shaft 13 at the top of the draw-off mechanism is smaller, the distance between a draw-off position and a needle board opening is ensured to be smaller than that in the traditional accessory draw-off mechanism, and the application amount of initial yarns is further reduced, thereby reducing the application cost.
Description
Technical field:
The present invention relates to the Knitting Machinery field, particularly a kind of compact conformation, the Computerized flat knitting machine draw-off mechanism of high-efficiency and low-cost.
Technical background:
In the braiding of Computerized flat knitting machine, traction force is very big to the quality influence of product, the tractive value that must change machine according to the structure and the amplitude of new assembling-disassembling.The draw-off mechanism of Computerized flat knitting machine is paid pulling roll and tractive comb and is formed by main pulling roll, is characterized in the velocity of rotation by programme-control tractive motor, changes the size of traction force.The effect of draw-off mechanism, except the tractive work of finishing knitting cycle, leading important still is that the fabric after the lopping is drawn from needle-bar crack mouth.Straight-bar machines draw-off mechanism at present commonly used mainly contains two kinds of Weight type draw-off mechanism and roller formula draw-off mechanisms.Roller formula draw-off mechanism is than Weight type draw-off mechanism complexity, and application form has multiple.Fabric is combed internode from needle-bar actinal surface to tentering, because the limit, two ends laterally is being restricted, promptly presents the phenomenon that the limit, two ends is inwardly distorted after bearing tension force.Thereby the coil on both sides, the tension force that bears in stringer is bigger, so vertical density will occur at the edge little, the irregular phenomenon that lateral density is big or because the caused roller of the elastical retraction of fabric reverses situation, that need to regulate the batching roller presses its complex structure of degree, not compact, production efficiency and cost are undesirable.
The Computerized flat knitting machine draw-off mechanism that the purpose of this invention is to provide a kind of high-efficiency and low-cost, particularly a kind of compact conformation, can make the distance of tractive position and needle plate littler by programme-control, can further reduce the consumption of gauze kerchief worn on a woman's head, reduce use cost, the tractive effect is more smooth-going, uniformly the Computerized flat knitting machine draw-off mechanism.
Technical scheme:
A kind of Computerized flat knitting machine draw-off mechanism of high-efficiency and low-cost is made up of main draw-off mechanism and secondary draw-off mechanism.Main pulling roll is made up of 24 cloth winding wheels, each one group of front and back.Secondary pulling roll 6 is the control rod iron of a band garden curved tooth shape.The tractive mode that main pulling roll and secondary pulling roll are traditional all is to rotate the traction action that realizes braided fabric by the mutual interlock of two groups of (root) pulling roll in front and back, and draw-off mechanism of the present invention is by the tractive belt mouth rubbing action each other on the two groups of pulling roll in front and back fabric to be carried out tractive.The tractive action of tractive belt mouth is driven by the power of rubbing by cloth beam 14.Draw-off mechanism of the present invention has following characteristics:
(1) compact conformation because compress axle 13 diameters on top are littler, can make the littler apart from this traditional secondary draw-off mechanism of tractive position and needle plate mouth, can further reduce the consumption of gauze kerchief worn on a woman's head, thereby reduces use cost.
(2) owing to adopt smooth pulling roll to carry out work, for the pulling roll of profile of tooth, littler to the tractive deformation effect of fabric, the tractive effect is more smooth-going, evenly.
(3) cost is lower, reduces manufacturing cost.
Embodiment further tells about the present invention below in conjunction with accompanying drawing.Description of drawings:

Concrete enforcement:
The draw-off mechanism of Computerized flat knitting machine is mainly paid pulling roll, 7-sinker bed, 8-sinker, 9-knitting needle, 10-gear piece by 1-master's pulling roll, 2-needle-bar pedestal, 3-needle-bar, 4-Neilsbed plug-in sheet, 5-fabric, 6-and is formed.Wherein main as shown in Figure 2 pulling roll 1 plays main traction action.The size of traction force can influence the density of fabric, so when the structure of fabric and fabric width changed, the size that needs rationally to regulate traction force adapted with the requirement with deisgn product.The action of main pulling roll is by the tractive Motor Control, and changes the velocity of rotation of motor by computer program, thus the size of control traction force.The torque value of motor (traction force and secondary tractive clamping force) has multistage available by the knitting program decision, and can adjust at any time in the braiding process.Based on the These characteristics of torque motor,, and just can obtain more satisfactory tractive effect according to the adjustment of braiding situation according to given corresponding traction force of fabric characteristics different on the garment piece and secondary tractive clamping force parameter.
As shown in Figure 1 be: a kind of Computerized flat knitting machine draw-off mechanism of high-efficiency and low-cost is made up of main draw-off mechanism and secondary draw-off mechanism.Main pulling roll is made up of 24 cloth winding wheels, each one group of front and back.Secondary pulling roll 6 is the control rod iron of a band garden curved tooth shape.Main pulling roll and secondary pulling roll tradition all are to rotate the traction action that realizes braided fabric by the mutual interlock of two groups of (root) pulling roll in front and back, and draw-off mechanism of the present invention is by the tractive belt mouth rubbing action each other on the two groups of pulling roll in front and back fabric to be carried out tractive.The tractive action of tractive belt mouth is passed through frictional force drives by cloth beam 14.Because it is littler to adopt smooth pulling roll to carry out work tractive deformation effect to fabric for the tractive Kun of traditional profile of tooth, the tractive effect is more smooth-going, even.Draw-off mechanism of the present invention has following characteristics:
(1) compact conformation because compress axle 13 diameters on top are littler, can make the littler apart from this traditional secondary draw-off mechanism of tractive position and needle plate mouth, can further reduce the consumption of head yarn raising, thereby reduces use cost.
(2) owing to adopt smooth pulling roll to carry out work, for the pulling roll of profile of tooth, littler to the tractive deformation effect of fabric, the tractive effect is more smooth-going, evenly.
(3) cost is lower, reduces manufacturing cost.
