Description

Technical Field

[0001] The utility model relates to the technical field of knitting, in particular to a knitting needle assembly and a jacquard machine using the knitting needle assembly. Background Art

[0002] Jacquard circular knitting machine, scientifically known as circular knitting machine or circular knitting machine, has developed rapidly due to its multiple loop forming systems, high speed, high output, fast shape change, good fabric quality, few processes and strong product adaptability.

[0003] A Chinese patent with announcement number CN204550951U discloses a jacquard machine, comprising a frame, a needle cylinder and a jacquard device, wherein the needle cylinder is connected to the frame, and the jacquard device is installed on the frame, and is characterized in that the jacquard device comprises a terry jacquard device for forming a terry jacquard cloth and a single-sided jacquard device for forming a single-sided jacquard cloth, and the terry jacquard device and the single-sided jacquard device are both installed on the frame and can work simultaneously.

[0004] Although this jacquard machine can perform terry jacquard and single-sided jacquard effects on fabrics at the same time, in actual use, it is sometimes necessary to weave fabrics with transfer jacquard. However, when performing transfer jacquard, the knitting needles of the existing jacquard machines sometimes fail to catch the loops, resulting in a low yield rate of the fabric jacquard. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a knitting needle assembly, which has the effect of improving the success rate of the knitting needle catching the coil and improving the yield rate of the cloth.

[0006] The above-mentioned invention object of the utility model is achieved through the following technical solutions:

[0007] A knitting needle assembly comprises a first knitting needle and a second knitting needle, wherein the first knitting needle and the second knitting needle are both provided with a needle tongue, the first knitting needle is provided with a loop expander for expanding the coil, the loop expander is located below the needle tongue of the first knitting needle, the loop expander is provided with an area for accommodating the passage of the second knitting needle, and the second knitting needle passes through the loop expander and is arranged parallel to the first knitting needle.

[0008] By adopting the above technical solution, when the jacquard pattern needs to be transferred, the coil is eaten by the first knitting needle and moves downward with the traction force until it moves to the coil expander and is stretched by the coil expander. At this time, the second knitting needle is driven to move upward into the coil expander and pass through the coil at the same time. Then, the first knitting needle is driven to move downward, and the coil is detached from the coil expander. At the same time, the second knitting needle also moves downward, and the coil is eaten by the second knitting needle to complete the jacquard pattern transfer.

[0009] In a preferred example, the utility model can be further configured as follows: the ring expander includes a syringe arranged along a vertical direction, and the top surface of the syringe is arranged to be a slope surface from high to low.

[0010] By adopting the above technical solution, after the coil is engaged by the first knitting needle, it moves downward along the slope surface of the needle cylinder, and at the same time the coil is stretched open.

[0011] In a preferred example, the utility model can be further configured as follows: a first limiting rod is provided at the bottom of the slope surface to prevent the coil from sliding off the slope surface.

[0012] By adopting the above technical solution, the first limiting rod blocks the coil from moving downward, thereby preventing the coil from sliding off the slope surface.

[0013] In a preferred example, the utility model can be further configured as follows: the syringe is provided with an opening along its length direction.

[0014] By adopting the above technical solution, it is convenient to install the second knitting needle into the needle cylinder of the first knitting needle.

[0015] In a preferred example, the utility model can be further configured as follows: steps are provided on the slope surface.

[0016] By adopting the above technical solution, since the coil is easy to slide on the slope surface, the step can play a certain limiting role.

[0017] In a preferred example, the utility model can be further configured as follows: the ring expander includes a half ring that is arranged obliquely, and both ends of the half ring are arranged at low positions.

[0018] By adopting the above technical solution, after the coil is engaged by the first knitting needle, it moves downward along the half ring, and at the same time the coil is stretched open.

[0019] In a preferred example, the utility model can be further configured as follows: the semi-ring port is provided with a second limiting rod to prevent the coil from falling off.

[0020] By adopting the above technical solution, the second limiting rod blocks the coil from moving downward, thereby preventing the coil from sliding off the slope surface.

[0021] A jacquard machine, characterized in that it includes multiple knitting needle assemblies as described in the above technical solution, and also includes a lower cylinder and a jacquard assembly, wherein the first knitting needle and the second knitting needle are installed on the cylinder body in a spaced and surrounding manner, and the second knitting needle in the same group of the knitting needle assemblies is located in the needle cylinder of the first knitting needle.

[0022] By adopting the above technical solution, when the jacquard pattern needs to be transferred, the coil is eaten by the first knitting needle and moves downward with the traction force until it moves to the coil expander and is stretched by the coil expander. At this time, the second knitting needle is driven to move upward into the coil expander and pass through the coil at the same time. Then, the first knitting needle is driven to move downward, and the coil is detached from the coil expander. At the same time, the second knitting needle also moves downward, and the coil is eaten by the second knitting needle to complete the jacquard pattern transfer.

[0023] In summary, the present invention includes at least one of the following beneficial technical effects:

[0024] 1. When the jacquard pattern needs to be transferred, the coil is eaten by the first knitting needle and moves downward with the traction force until it moves to the coil expander and is stretched by the coil expander. At this time, the second knitting needle is driven to move upward into the coil expander and passes through the coil at the same time. Then, the first knitting needle is driven to move downward, and the coil is detached from the coil expander. At the same time, the second knitting needle also moves downward, and the coil is eaten by the second knitting needle to complete the jacquard pattern transfer, thereby improving the success rate of the knitting needle eating the coil and improving the yield rate of the fabric.

[0025] 2. The limit rod can stop the coil from moving downward and prevent the coil from sliding off the slope. BRIEF DESCRIPTION OF THE DRAWINGS
