Description

Auxiliary drawing structure of integrated ready-made garment computerized flat knitting machine

Technical Field

The utility model relates to a computerized flat knitting machine weaves technical field, especially an auxiliary tractive structure of integrative clothing computerized flat knitting machine.

Background

As is known, a computerized flat knitting machine is a double-needle-plate latch weft knitting machine, and its cam device is like a group of plane cams, and the stitches of the knitting needles can be fed into the grooves of the cams, and the cams are moved to force the knitting needles to make regular lifting movement in the grooves of the needle plates, and the yarns can be knitted into knitted fabrics by means of the actions of needle hooks and needle latches. The general weaving process is as follows: in the process of ascending the knitting needle, the coil gradually withdraws from the hook, opens the latch and withdraws from the latch to be hung on the needle rod; during the descending process of the knitting needles, the hooks catch the yarns laid by the new pads and draw and bend the yarns into loops, meanwhile, the original loops are separated from the hooks, the new loops penetrate through the old loops and are connected with the old loops in series, and the loop strings knitted by a plurality of knitting needles are connected with each other to form the knitted fabric.

In order to prevent the loop in the hook from rising with the rise of the knitting needle, that is, to prevent the loop from floating up, a conventional computerized flat knitting machine is generally provided with a drawing device for continuously drawing down the knitted fabric.

At present, the traction device installed between the left wall plate and the right wall plate of the computerized flat knitting machine is generally roller assemblies which are symmetrically arranged in the front and back direction, when the traction device works, two symmetrical roller assemblies with opposite rotation directions are used for clamping a braided fabric and downwards drawing the braided fabric, but the traction device is only suitable for drawing the whole braided fabric, for the braided fabric needing to be drawn locally in the knitting process, a balancing weight with proper weight and height can be arranged at the part needing to be drawn locally through manpower, the local part of the braided fabric is downwards drawn by the gravity of the balancing weight, for example, when knitting sweater, in order to realize digging collar and shoulder, the local traction is needed to be carried out on the part with inconsistent front and back lengths, such as collar and shoulder of the sweater. Because the operation mode needs to manually arrange the balancing weight at the bottom of the woven fabric to pull the local part of the woven fabric downwards each time, the automation degree is lower, and the labor intensity of production workers is also high.

Later, some manufacturers designed segmented roller assemblies below the original roller assemblies, and defined the upper roller assembly as the elevated roller and the lower segmented roller assembly as the auxiliary roller.

Segmented roller assemblies (auxiliary rollers) have been patented in the market, such as: the utility model discloses a chinese utility model patent of publication No. CN 214694565U, name "a computerized flat knitting machine sectional type roller", and chinese utility model patent application of publication No. CN 113026190A, name "roller adjusting device". The auxiliary roller can separately adjust the traction force applied to the garment piece in sections according to the requirements of the knitted fabric in the process of knitting the garment, so that different parts of the whole garment piece can be selectively and locally drawn, and the requirement of actual production of the fabric is effectively met.

However, it is known that when knitting a garment, the front garment piece and the rear garment piece are both attached to each other, and although the local parts of the garment pieces can be pulled down individually by the surface friction force of the sectional roller and the pressing force of the garment pieces, because a certain friction force exists between the front and rear garment pieces attached to each other, the friction force is affected by the friction force, in the actual production process, a production worker is usually required to debug the sectional roller for a long time, especially to adjust the pressing force and the friction force exerted on the garment pieces by the sectional roller, so that the sectional roller can finally realize the pulling effect of the front and rear garment pieces at different speeds, and the whole process is very time-consuming and labor-consuming. In addition, even if a production worker properly adjusts the position and the pressing force of the sectional roller, the local accurate downward drawing of the garment pieces is difficult to completely ensure due to the existence of friction force between the two attached front and rear garment pieces during downward drawing.
