Description

Technical Field

[0001] This utility model relates to the field of thread adjusting machine technology, and in particular to a needle barrel cut structure for a double-sided thread adjusting machine with jacquard weave. Background Technology

[0002] In the knitting and textile industry, double-sided yarn-adjusting machines are widely used because they can knit double-sided fabrics with rich colors and diverse patterns. These machines typically have jacquard structures in the upper and lower cylinders and use a yarn-adjusting mechanism to switch between different yarns, thus forming complex jacquard patterns on the fabric surface. During knitting, the yarn-adjusting head needs to accurately guide the yarn into the openings of the upper needle plate and lower cylinder, where the needles pick it up and form loops. The cut edge, also known as the loop position or special knitting position, is a critical area on the cylinder. During yarn-adjusting knitting, this position needs to handle two or more yarns simultaneously, and the load, friction, and yarn tension experienced by the needles here are much higher than in normal knitting areas.

[0003] Currently, the needles used in the cut-edge section of double-sided yarn-adjusting machines on the market have the same needle thickness as those used in the normal knitting area. Typically, thinner needles, such as 0.41mm, are used in the normal knitting area to ensure knitting flexibility and fabric smoothness. However, applying such thin needles of the same thickness to the high-load cut-edge section has certain drawbacks. Because the needles in the cut-edge section need to hook multiple yarns simultaneously during yarn adjustment, the stress is concentrated, making the needles in this area more prone to wear, bending, and even breakage—commonly known as "broken needles."

[0004] Frequent needle breakage at the cut edge directly leads to a significant increase in unplanned downtime during production. Each downtime requires maintenance and needle replacement, severely impacting the continuous operating efficiency of the equipment and overall production efficiency. Furthermore, frequent needle breakage can also cause defects in fabric quality, increasing raw material waste and the defect rate. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art and provides a needle barrel cut structure for a double-sided jacquard knitting machine, which helps to extend the service life of knitting needles, reduce downtime maintenance frequency, and improve work efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A needle barrel cut structure for a double-sided jacquard knitting machine includes a needle barrel body, a needle plate disposed on the upper part of the needle barrel body, the needle plate including an upper jacquard structure with an upper needle plate nozzle; a lower jacquard structure disposed on the lower part of the needle barrel body with a lower needle barrel nozzle, the upper needle plate nozzle corresponding to the lower needle plate nozzle, the upper jacquard structure and the lower jacquard structure together constituting a double-sided knitting system; The syringe body is divided into a normal knitting area and a cut area. The cut area is located above the lower syringe nozzle and corresponds to the working position of the thread adjustment head. The knitting needles installed in the cut area are thickened knitting needles, and their needle body thickness is greater than that of the knitting needles installed in the normal knitting area.

[0007] Furthermore, the needle body thickness in the normal knitting area is 0.38 mm to 0.42 mm.

[0008] Furthermore, the needle body thickness of the knitting needle in the normal knitting area is 0.41 mm.

[0009] Furthermore, the thickness of the thickened knitting needle is 0.48 mm to 0.55 mm.

[0010] Furthermore, the thickness of the thickened knitting needle is 0.50 mm.

[0011] Furthermore, the number of thickened knitting needles distributed along the circumference of the needle cylinder in the cut area is 60 to 150.

[0012] Furthermore, the number of thickened knitting needles distributed in the cut area is 70 to 100.

[0013] Furthermore, the cut area is equipped with thickened knitting needles arranged in an intermittent needle-pulling manner, so that the actual number of thickened knitting needles installed in the cut area is less than the total number of needle slots.

[0014] Furthermore, the interval needle-pulling method is either a half-pulling or a third-pulling.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention enhances the mechanical properties of the cut area by configuring knitting needles of different thicknesses for the normal knitting area and the cut area, thereby helping to extend the service life of the knitting needles, reduce downtime maintenance frequency, and improve work efficiency.

[0016] The accompanying drawings are provided to further illustrate the present invention and, together with the embodiments of the present invention, are used to explain the present invention. They do not constitute a limitation thereof. In the drawings: Figure 1 This is a schematic diagram of the needle barrel cut structure of the jacquard double-sided thread adjusting machine described in this utility model.

[0017] In the diagram: 1. Upper jacquard structure; 2. Upper needle plate nozzle; 3. Lower jacquard structure; 4. Lower needle cylinder nozzle; 5. Adjusting thread end. Detailed Implementation

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] like Figure 1 As shown, this utility model claims protection for a needle cylinder cut-out structure for a double-sided jacquard knitting machine, including a needle cylinder body, a needle plate disposed on the upper part of the needle cylinder body, the needle plate including an upper jacquard structure 1, the upper jacquard structure 1 having an upper needle plate nozzle 2. A lower jacquard structure 3 is disposed at the lower part of the needle cylinder body, the lower jacquard structure 3 having a lower needle cylinder nozzle 4. The upper needle plate nozzle 2 and the lower needle cylinder nozzle 4 are arranged vertically correspondingly, so that the upper jacquard structure 1 and the lower jacquard structure 3 together constitute a complete double-sided jacquard knitting system, realizing the functions of double-sided jacquard and yarn adjustment.

[0020] In this embodiment, the circumferential direction of the syringe body is clearly divided into a normal knitting area and a cut area. The cut area is located directly above the lower syringe nozzle 4 and precisely corresponds to the working position of the yarn adjuster 5. The yarn is switched by the frequent movement of the yarn adjuster 5 in this area.

[0021] For normal knitting areas, standard thickness knitting needles are installed, with a needle body thickness preferably between 0.38 mm and 0.42 mm. In this embodiment, it is preferably 0.41 mm. This thickness balances knitting flexibility and needle strength.

[0022] For the cut area, all needles are fitted with thickened needles, with a needle body thickness greater than that of normal needles, preferably 0.48mm to 0.55mm, and in this embodiment, preferably 0.50mm. The thickened design significantly improves the rigidity and impact resistance of the needles, effectively resisting stress concentration caused by the yarn adjustment action 5, and reducing deformation and wear.

[0023] Furthermore, the number of thickened needles distributed along the circumference of the needle cylinder in the cut area is preferably 60 to 150, and in this embodiment, it is preferably 70 to 100. To optimize the yarn tension distribution and knitting density, the thickened needles can be arranged using an intermittent needle-dropping method, meaning that the actual number of thickened needles installed in the cut area is less than the total number of needle slots in that area. Specifically, the needle-dropping ratio can be one-half or one-third; one-half means installing one thickened needle in every other needle slot; one-third means installing two thickened needles in every three needle slots. This arrangement ensures structural strength while avoiding excessive fabric density, thus improving fabric quality.

[0024] The working process of this utility model is as follows: When the double-sided yarn adjusting machine is running, the yarn adjusting head 5 frequently switches yarns in the cut area. The thickened needles, due to their large thickness, possess strong rigidity and stable impact resistance, maintaining precise matching between the needle hook and the needle latch. The standard needles in the normal knitting area ensure overall knitting efficiency and fabric uniformity; the upper and lower jacquard structures achieve efficient double-sided yarn adjusting jacquard knitting through coordinated movements of corresponding nozzles.

[0025] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
