Description

Feather yarn crochet machine and crochet device therein

technical field

The invention relates to a crochet machine used in the textile industry, in particular to a feather yarn crochet machine and a crochet device therein.

Background technique

At present, a kind of traditional feather yarn crochet machine, as shown in Figure 1, its structure generally comprises: frame (belonging to the conventional technology in this field, not shown in the figure), the hook plate 8 that is movably arranged on the frame , weft needle plate 5, warp needle plate 1, several self-closing crochet needles 7 equidistantly arranged on the crochet needle plate 8, several weft yarn needles 4 equidistantly arranged on the weft needle plate 5, and several equidistantly arranged on the weft needle plate 5 The warp needles 2 on the warp needle board 1 and the hook driving device arranged on the frame for driving the crochet needle board 8 to move, the weft needle driving device for driving the weft needle board 5 to move, and the weft needle driving device for driving the warp needle board 1 to move The warp yarn needle driving device, the weft yarn unwinding device, the warp yarn unwinding device and the yarn winding device mainly composed of a pair of winding wheels 13 and their driving devices. The frame is also provided with a needle bed 10. The bed 10 is provided with crochet grooves corresponding to the self-closing crochet needles 7 one by one, and the self-closing crochet needles 7 are arranged in the corresponding crochet grooves in a one-to-one correspondence. One side direction of plate 1 is also provided with pressing plate 9, and also is provided with knife rest 12 below needle bed 10, and knife rest 12 is provided with several cutting knives 11 arranged at equal intervals (cutter 11 is used for cutting track yarn 19 weft yarn cut in). The working process of the crochet machine is as follows: firstly, the self-closing crochet needles 7 are driven by the eccentric wheel in the crochet needle driving device in the needle bed 10 to perform two actions before and after. 3 Driven by the warp needle 2, do two movements of left and right and up and down at the same time, wind the warp yarn 3 onto the self-closing crochet needle 7, at the same time, the weft yarn needle 4 drives the weft yarn 6 to swing left and right, and the yarn loop woven by the warp yarn 3 is woven In it, then, the self-closing crochet needle 7 is retracted into the needle bed 10 under the drive of the eccentric wheel, so that the old coil is disengaged from the self-closing crochet needle 7, and is driven downward by the winding wheel 13. Then, the self-closing crochet needle 7 Stretch out needle bed 10 again, start next round of circulation. As shown in Figure 3, when the flat track yarn 19 (that is commonly called " cloth ") of the warp knitting weft insertion structure formed by warp yarn and weft yarn passes through the cutting knife 11 on the traveling line that is positioned at track yarn 19, Blade 11 just cuts corresponding track yarn 19 into a sliver (only cuts weft yarn 6), forms finished product feather yarn 20 (becoming yarn). The crochet machine of above-mentioned structure is to determine the spacing of warp yarn 3 according to the length of feather, then according to the length of needle board (the length of all needle boards is all equal) arrange the number of track yarn 19, because the length of needle board or hook The width of the weaving machine is limited, and the longer the feather of the feather yarn (into yarn) produced, the fewer the number of track yarns produced, and the lower the output.

As a preferred solution, in the crochet device in the feather yarn crochet machine, the needle bed is close to the track yarn elastic pressing part, and close to the track yarn elastic pressing part A yarn outlet groove is opened on one side of the yarn.

As a preferred solution, in the crochet device in the described feather yarn crochet machine, the specific structure of the tongue-shaped crochet needle includes: a crochet bar, the tail of the crochet bar is installed on the crochet plate, and the crochet bar The head is provided with a needle hook, and the crochet rod is movably hinged with a latch matching the needle hook near its head. When the needle latch falls to the needle hook, the top of the needle latch is closed with the top of the needle hook.

As a preferred solution, in the crochet device in the feather yarn crochet machine, the needle retaining plate is provided with retaining needle grooves corresponding to the retaining needles one by one, and the retaining needles one by one One pair of them is correspondingly locked in the corresponding needle retaining groove, forming a detachable plug-in structure.

As a preferred solution, in the crochet device of the feather yarn crochet machine, the orbital yarn elastic pressing part is an elastic curved metal wire.

As a preferred solution, in the crochet device of the feather yarn crochet machine, a needle stopper adjustment mechanism for adjusting the angle of the needle stopper is arranged between the needle stopper and the frame.

As a preferred solution, in the crochet device in the feather yarn crochet machine, the angle between the loop buffer bar and the vertical direction is between 5 and 15 degrees;

The present invention also provides a feather yarn crochet machine, comprising: a frame, on which a weft yarn unwinding device, a warp yarn unwinding device, and a yarn winding device are arranged, and a plurality of knives are arranged on corresponding The cutting knife on the track yarn travel route, the crochet device according to the present invention, the hook driving device for driving the movement of the crochet needle board, the weft needle driving device for driving the movement of the weft needle board, the knitting device for driving the movement of the warp needle board The warp needle drive device. The yarn output produced by the feather yarn crochet machine is 3-5 times that of the traditional feather yarn crochet machine.

The beneficial effects of the present invention are: the present invention sets the needle retaining plate, and sets the needle retaining plate on the needle retaining plate relative to the position between two corresponding weft needles, so that the tongue-shaped crochet hooks can be connected after the weft yarn is fixed. During the shrinking process, the stopper blocks the weft yarn, making it elongated, and finally forms the track yarn in the shape shown in Figure 4. In this way, long feather yarns can be produced without increasing the distance between adjacent crochet needles, so that the number of yarns can be greatly increased while the length of all needle plates remains unchanged (the width of the crochet machine does not change). Thereby the output of feather yarn is improved.
