Description

Technical Field

[0001] The present invention discloses an anti-wrap and spandex terry jacquard machine, belonging to the field of jacquard circular weft knitting machines, and particularly relates to an anti-wrap and spandex terry jacquard machine. Background Art

[0002] The jacquard circular weft knitting machine, also known as the circular weft knitting machine or the circular knitting machine in academic terms. Due to the large number of loop-forming systems, high rotational speed, high output, fast pattern change, good fabric quality, few processes, and strong product adaptability of the circular knitting machine, it has developed rapidly.

[0003] At present, most of the terry jacquard machines on the market are mainly positive-wrap jacquard machines. For some two-station anti-wrap machines, adding spandex is not stable. For three-station terry machines, due to the too long distance between the yarn feeding position and the loop shedding position, the spandex reverses, resulting in uneven fabric surface and it is simply impossible to add spandex. They are most widely used for making curtains and sofa fabrics. After post-finishing and sanding, the terry is not tight and easy to fall off. In order to develop markets such as clothing and fabrics and increase the machine adaptability, this invention patent solves this problem. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-wrap and spandex terry jacquard machine to solve the above problems.

[0005] The present invention realizes the above purpose through the following technical solutions. An anti-wrap and spandex terry jacquard machine includes:

[0006] Machine body: installed with a selector.

[0007] Large gear disk: a large gear disk rotating in the middle of the machine body.

[0008] Lower needle cylinder: one end is fixedly installed with the large gear disk, the other end is fixedly installed with a sinker ring, and it is internally provided with lower knitting needles.

[0009] Sinker ring: internally provided with upper jacquard blades, sinker blades cooperating with the upper jacquard blades, and auxiliary blades arranged on the sides of the upper jacquard blades and sinker blades.

[0010] Preferably, the sinker blade is provided with a first blade hammer, a first blade nose, a second blade nose, and a sinker throat.

[0011] Preferably, the auxiliary blade is provided with a second blade hammer, an auxiliary throat, and convex points with a yarn splitting effect.

[0012] Preferably, an angle is formed between the convex points and the auxiliary throat.

[0013] Preferably, the angle between the auxiliary throat and the convex points is 30°.

[0014] Preferably, a plurality of grooves are provided in the sinker ring. The grooves are respectively provided with upper jacquard blades, sinkers and auxiliary blades. The sinkers are arranged between the upper jacquard blades and the sinker ring, and the auxiliary blades are arranged on one side of the upper jacquard blades and the sinkers.

[0015] Preferably, the upper jacquard blade is provided with blade feet for cooperating with the selector, and the upper jacquard blade is clamped with the sinker (7).

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: After yarn feeding, the auxiliary blade pops out. The upper and lower parts of the provided bump are used to separate the base yarn from the spandex, so as to achieve the effect of separating the yarns and avoid the entanglement and interweaving of the spandex and the base yarn. When knitting off the loop quickly, the auxiliary blade retracts a certain distance, so that the spandex slides down below the bump, and the auxiliary blade continues to pop out to push out the spandex and the base yarn to a position close to the back of the needle. At this time, the base yarn is at the lower part in the needle hook, the spandex is in the middle, and the wool yarn is at the upper part. After the lower needle continues to knit off the loop, the base yarn is exposed on the front side, the spandex is in the middle, and the wool yarn is on the back side, forming a reverse wrapping effect.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] This embodiment provides a reverse-wrap spandex terry jacquard machine, as Figures 1-3 shown, the reverse-wrap spandex terry jacquard machine of the first embodiment of this embodiment includes:

[0034] Machine body: A selector 1 is installed on it;

[0035] Large gear disk: A large gear disk that rotates in the middle of the machine body;

[0036] Lower needle cylinder: One end is fixedly installed with the large gear disk, and the other end is fixedly installed with a sinker loop; 4, and lower knitting needles 2 are arranged inside it;

[0037] Knit loop: Inside it, there are upper jacquard blades 5, sinker blades 7 that cooperate with the upper jacquard blades 5, and auxiliary blades 6 arranged on the sides of the upper jacquard blades 5 and sinker blades 7. The sinker blade 7 is provided with a first blade 71, a first blade nose 72, a second blade nose 73, and a sinker throat 74. The auxiliary blade 6 is provided with a second blade 61, an auxiliary throat 62, and a bump 63 with a yarn splitting effect. There is an angle formed between the bump 63 and the auxiliary throat 62, and the angle between the auxiliary throat 62 and the bump 63 is 30°. There are several grooves inside the knit loop 4, and the upper jacquard blades 5, sinker blades 7, and auxiliary blades 6 are all arranged in the grooves. The sinker blade 7 is arranged above the upper jacquard blade 5, and the auxiliary blade 6 is arranged on one side of the upper jacquard blade 5 and the sinker blade 7. The upper jacquard blade 5 is provided with a first step for moving the auxiliary blade 6.

[0038] Reference Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown in the figures, at the yarn feeding position of point A, for the ordinary machine, the ground yarn 101 and the spandex 102 are wound together at the position of I, resulting in the phenomenon of reverse spandex 102 on the fabric surface. When not jacquarding, the auxiliary blade 6 is pushed out at the B position, and the bump 63 of the auxiliary blade 6 separates the ground yarn 101 and the spandex 102, keeping them in the upper and lower parts of the bump 63.

[0039] When the machine runs to the C position, the auxiliary blade 6 retracts a certain distance. The spandex 102 is pulled down by the knitting needle 2 at point E, and the spandex 102 slides down the bump 63 of the auxiliary blade 6, remaining above the ground yarn 101.

[0040] When the machine runs to the D position, the auxiliary blade 6 controls the ground yarn 101 and the spandex 102 to be pushed out a small distance towards the back of the needle, making the ground yarn 101 and the spandex 102 closer to the back of the needle and stabilizing the spandex 102 on the ground yarn 101. When the machine runs to point E, the auxiliary blade 6 has retracted.

[0041] Figures 4 to 14 As shown in the figures, when knitting low pile jacquard, the sinker blade 7 is pushed out, and the first blade nose 72 hooks the pile yarn 103. Referring to the D and E positions, a low pile loop effect is formed on the fabric surface.

[0042] Figures 4 to 14 As shown in the figures, when knitting high pile jacquard, the sinker blade 7 is pushed out, and the second blade nose 73 hooks the pile yarn 103. Referring to the D and E positions, a high pile loop effect is formed on the fabric surface.

[0043] This solution does not interfere with the actions of high pile and low pile jacquarding, and the sinker throat 74 can be widened, using the auxiliary throat 62 to assist in loop shedding.
