Description

Computerized flat knitting machine roller take-up mechanism

Technical field

The invention relates to a computerized flat knitting machine roller take-up mechanism, belonging to the technical field of computerized flat knitting machines.

Background technique

As shown in FIG. 1 , a computerized flat knitting machine high position roller take-up mechanism includes a first take-up bobbin and a second take-up bobbin, and the first take-up bobbin includes a first screw 2 and a first roller 1 And the first roller hose 3, a support block 4 is further disposed between the first screw 2 and the first roller 1. The first screw 2 is used as a driving wheel, and the first roller 1 is driven as a driven wheel to rotate the first roller hose 3 disposed outside the first screw 2 and the first roller 1; the second winding bobbin includes The second screw 6, the second roller 5 and the second roller hose 7, and a support block 8 are further disposed between the second screw 6 and the second roller 5. The second screw 6 acts as a driving wheel, and the second roller 5 acts as a driven wheel to drive the second roller hose 7 that is sleeved outside the second screw 6 and the second roller 5; the first roller hose 3 and the second roller A nip that pulls the take-up knit 10 is left between the hoses 7.

The inner wall of the first roller hose and the second roller hose adopts a straight rib type, and the responsive screw rib is engaged, and the concave and convex surface is contacted, and is used to increase the friction between the screw and the hose when rotating, so that the hose drives the roller together. Rotate and take up the fabric that has just been woven.

The main feature of the high-level roller is that it can save the weaving material. Due to certain process requirements, the yarns in the gap between the continuous woven fabrics can be pulled in time.

The outer surface of the roller is generally a polished surface, and the outer surface of the straight, horizontal and rectangular lines is added to increase the friction of the wound fabric, so that the winding fabric can be smoothly dropped.

However, as shown in Fig. 2, the width of the width of the knitted fabric 10 when it is taken up is always smaller than the width when the needle bed is just knitted. As can be seen from Fig. 2, at the needle bed. The width of the braid 10 at 9 is greater than the width of the braid 10 at the second roller hose 7. This is because once the fabric is formed, the knitted fabric 10 will naturally shrink, so when knitting, the new stitch on the knitting needles on both sides of the knitting will shrink inward, so that the stitch on the knitting needle has a diagonally pulled angle, so that the knitting needle Deformation occurs during weaving, and the smoothing, shifting, and turning functions cannot be achieved smoothly. Especially the braids with high density required by the process often have needle leaks and rotten Edge and other phenomena.

Summary of the invention

SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide a computerized flat knitting machine roller take-up mechanism which makes the width of the spread of the knitted fabric tend to be the width of the width when the needle bed is just knitted.

In order to solve the above technical problem, the technical solution of the present invention is:

A computerized flat knitting machine roller take-up mechanism comprising a first take-up bobbin and a second take-up bobbin, the first take-up bobbin comprising a first screw, a first roller and a first roller hose, The first screw is used as a driving wheel, the first roller is driven as a driven wheel, and the first roller is disposed outside the first screw, and the first roller is rotated; the second winding tube includes a second screw and a second a roller and a second roller hose, the second screw acts as a driving wheel, and the second roller acts as a driven wheel to rotate the second roller hose disposed outside the second screw and the second roller; the first roller hose and the first roller There is a nip between the two roller hoses for pulling the winding fabric, and the outer surface of the left end of the first roller hose, the outer surface of the right end, the outer surface of the left end of the second roller hose, and the outer surface of the right end of the second roller have more than one outer surface. In the form of a corrugation, the corrugations are distributed in a spiral shape.

S represents the outer surface of the left end of the first roller hose has a spiral distribution corrugated shape, T represents the outer surface of the right end of the first roller hose has a spiral distribution corrugated shape, and U represents the outer surface of the left end of the second roller hose has a spiral distribution corrugated shape , V represents the outer surface of the right end of the second roller hose has a spiral distribution corrugated shape. Such a spiral distribution ripple has 15 choices: S, T, U, V, ST, SU, SV, TU, TV, UV, STU, STV, SUV, TUV, STUV.

If the outer surface of the left end of the first roller hose is corrugated, the corrugation is a right-handed spiral. If the outer surface of the right end of the first roller hose is corrugated, the corrugation is a left-handed spiral; if the left end of the second roller hose is outside If the surface is corrugated, the corrugation is a left-handed spiral. If the outer surface of the right end of the second roller hose is corrugated, the corrugation is a right-handed spiral; the first roller rubber and the second roller hose are oppositely rotated to turn the braid toward When wound down, the corrugations expand the braid outward.

The outer surfaces of the left and right ends of the first roller hose and the second roller hose have spiral corrugations.

An outer surface having a spiral corrugation at a left end of the first roller hose is equal in length to an outer surface having a spiral corrugation at a left end of the second roller hose.

An outer surface having a spiral corrugation at a right end of the first roller hose is equal in length to an outer surface having a spiral corrugation at a right end of the second roller hose.

The first roller shell and the second outer surface of the second roller hose are parallel corrugated or rectangular.

The outer surface of the first roller hose having a spiral corrugation at the left end is different in length from the outer surface having a spiral corrugation at the right end thereof.

An outer surface having a spiral corrugation at a left end of the first roller hose and an outer surface having a spiral corrugation at a right end of the first roller hose bisect the outer surface of the first roller hose.

The pitch of the outer surface corrugations of the first roller hose is different, and the pitch of the outer surface corrugations of the second roller hose is different.

The invention can expand the fabric outward when the fabric is wound by the spiral corrugation, so that the coil generated by the weaving is vertically unwound on the knitting needle, so that the knitted side needle does not deform due to the shrinkage of the fabric, so that the deformation is caused. Smoothly uncoiled and transferred to normal weaving.

Beneficial technical effects:

1. It can effectively solve the problem that the knitting stitches of the two sides of the braided yarn are inclined inward due to the pulling and contracting of the braid. When the knitting needle is working under the inclined state, the insertion of the corresponding surface knitting needle into the transfer knitting needle reed will cause an error during the transfer, and this error will cause the knitting to leak the needle and the bad edge.

2. Due to the natural shrinkage of the width of the fabric, the tension of the side fabric is inclined inward, which increases the friction between the braid and the knitting needle during the unwinding, resulting in a difference in the time of the knitting of the different parts: the braid The knock-off time on both sides is significantly slower than the turn-off time of the intermediate fabric. This creates a bottleneck for the computerized flat knitting machine to increase the weaving speed, especially the time difference in the rapid turning of the knitting. By the outward expansion of the spiral corrugated woven fabric of the present invention, the reduced diagonalness of the woven needles on both sides of the fabric reduces the friction of the two sides of the draping cloth, so that the two sides are equally quickly dropped, which can improve The weaving efficiency of the machine head is quickly turned.

3. The original roller hose can't expand the braid when it is pulled down, because when weaving, the loop density triangle is the same command density requirement for the middle and the two sides of the knitting needle. ring. The braid produces natural shrinkage and pull, and because the position of the needle is fixed, it is pulled down and rolled on both sides of the fabric. When taking, the diagonal angle between the fabric coil and the knitting needle will be generated, and the friction between the coil and the knitting needle will be increased, so that the pulling force of the two sides of the fabric on the knitting needle will be larger than that of the middle winding of the fabric. Cashmere, cashmere and other short yarns with poor tensile strength are easily broken, which causes the fabric to have a bad edge and cannot be properly woven. The spiral corrugation of the present invention can solve the above problems and improve the flatness of the fabric.

4. The higher the weaving density of the fabric, the greater the shrinkage of the fabric after it is taken off. After the fabric is shrunk, the friction between the coils and the needles on both sides of the fabric is increased. For example, for high-density woven products: vamps, knee pads, covers, collars, etc., this will increase the difficulty of pinning, collecting, and knitting on both sides of the fabric. After being taken up by the outward expansion of the spiral corrugation, the problem caused by the product with high difficulty in weaving can be solved.

5. Long-term weaving work, when the high-density woven fabric is pulled down, the natural shrinkage of the fabric will cause the knitting needles on both sides to be pulled, the knitting needles work under the inclined state, and the loops are repeatedly looped. , causing severe fatigue loss of the knitting needle. Through the coiled corrugated take-up and timely expansion, the coils on both sides of the fabric are normally looped, uncoiled and dropped, thereby reducing the diagonal pulling of the fabric on the knitting needle, so that the knitting needle is kept in a straight state, and the knitting needle is reduced. Loss.

6. When the woven fabric is pulled up and pulled down, the woven knitting needles on both sides are inclined under the action of the shrinkage and pulling of the woven fabric, and are transferred, lapped, and detached in a tilted state, and the coil is doubled. On the inclined knitting needles, the coils are crowded, and the crowded coils on the knitting needles are easily rubbed against the toothed sheets on the side of the needle bed of the inclined needle bed, causing the yarn to be broken and broken, and the knitting cannot be performed normally. The spiral corrugations of the present invention can solve the above problems after being expanded outwardly and wound up.

7. The spiral corrugation of the invention expands and winds the two sides of the fabric outwardly, so that the woven fabric is normally vertical (the coil is perpendicular to the tooth gap of the needle bed), and the fabric can be quickly taken up to the gap between the woven fabrics. Start the veil. Because the newly-extending braid on both sides after the needle is placed requires the original braid to pull the cloth, and the angle of the diagonal pull is large to produce a floating line. The invention adopts the spiral expansion pulling to make the knitting material with the fast needle releasing speed to be vertically pulled, thereby improving the stability of the fast needle knitting and the knitting efficiency, and changing the original computerized flat knitting mechanism to be only longitudinal, not horizontal. At the same time pulling.

The invention of this new type of roller pulling structure has also expanded a new idea for designing products for designers who are studying braids, leading the development of the weaving industry.

8. The manufacture of the roller hose of the present invention and the manufacture of the original roller hose do not increase the cost of raw materials and manufacturing, can improve the knitting function and production efficiency, and reduce the waste of the woven fabric.

The inventive concept and the above-described embodiments can also be utilized in other roller mechanisms to perform the same function.

For example, in another mechanism of a roller take-up mechanism or the like, the mechanism includes two press wheels, and the driven press wheel rotates toward each other to pull the braid between the two press wheels downward. In the same manner, when the outer surface of the cloth wheel is corrugated, the corrugations are spirally distributed, and the corrugation expands the braid outward when the fabric wheel rotates toward the opposite direction. However, since the pressing wheel is wound downward, the two pressing wheels are in line contact, and the effect of expanding outward is not particularly large.

Another example is the existing roller structure: including two iron rollers, and the iron rollers are turned toward each other to fall into the knitted fabric. Row winding, as a modification, the outer surface of the iron roll also has spiral corrugations as employed in Examples 1-15.
