[0007] A sinker assembly comprises two sinkers and a cutter slidably arranged between the two sinkers. The sinker comprises a sheet body, a sheet tongue and at least one sheet nose, and a yarn hanging portion is arranged at the end of the sheet nose.

[0008] By adopting the above technical solution, when it is necessary to cut the yarn loop, the yarn hanging part on the sinker hooks the yarn loop, and the cutter cuts the yarn loop in the direction of the yarn loop, which greatly improves the success rate of cutting the yarn loop.

[0009] In a preferred example, the utility model can be further configured as follows: two sheet noses are provided, the two sheet noses are arranged in parallel up and down, wherein the sheet nose located at the upper side is shorter than the sheet nose located at the lower side, and the cutting blade is arranged in an inclined shape.

[0010] By adopting the above technical scheme, when the woven fabric has two yarn loops of high and low heights, the yarn hanging parts on the two sheet noses respectively hang the two yarn loops of high and low heights. After the yarn hanging parts hang the yarn loops, the cutter is driven to cut off the two yarn loops at the same time; in addition, two sheet noses of different heights can also correspond to two yarn loops of different heights, and the yarn loops of corresponding heights can be cut off, and the application range is also wider.

[0011] In a preferred example, the present invention can be further configured as follows: the yarn hanging portion includes a groove arranged near the end of the blade nose.

[0012] By adopting the technical solution, the groove can hang the yarn loop, making it easier for the cutter to cut the loop.

[0013] In a preferred example, the utility model can be further configured as follows: the groove is arranged to be a slope toward the rear end of the sheet nose, and the slope is arranged from high to low along the direction from the rear end of the sheet nose to the front end of the sheet nose.

[0014] By adopting the above technical solution, the groove is arranged as a slope toward the tail end of the nose, and the yarn loop enters the groove along the slope, thereby facilitating the yarn loop to enter the groove.

[0015] In a preferred example, the utility model can be further configured as follows: the end of the yarn hanging portion forms a hook shape along a trajectory from the top to the tail.

[0016] By adopting the above technical solution, the hook-shaped yarn hanging part can easily hang the yarn loop, thereby improving the success rate of cutting the loop.

[0017] A shearing and loop pile jacquard machine comprises any one of the sinker assemblies of the above technical solutions, and also comprises a needle cylinder, knitting needles arranged around the needle cylinder, and a jacquard assembly cooperating with the knitting needles.

[0018] By adopting the above technical solution, when it is necessary to cut the yarn loop, the yarn hanging part on the sinker hooks the yarn loop, and the cutter cuts the yarn loop in the direction of the yarn loop, which greatly improves the success rate of cutting the yarn loop.

[0019] In summary, the present invention includes at least one of the following beneficial technical effects:

[0020] 1. The yarn hanging part on the sinker hooks the yarn loop, and the cutter cuts the yarn loop in the direction of the yarn loop, which greatly improves the success rate of cutting the loop;

[0021] 2. When the woven fabric has two yarn loops of high and low heights, the yarn hanging parts on the two plate noses respectively hang the two yarn loops of high and low heights. After the yarn hanging parts hang the yarn loops, the cutter is driven to cut off the two yarn loops at the same time; in addition, two plate noses of different heights can also correspond to two yarn loops of different heights, cutting off the yarn loops of corresponding heights, and the application range is also wider.

The sinker 41 includes a sheet body 411, a sheet tongue 412 and a sheet nose 413. A yarn hanging portion 414 is provided at the end of the sheet nose 413.

[0029] The number of the sheet noses 413 is set according to the number of layers of hair height required on the woven fabric, and one, two, three or more sheet noses 413 may be set. This embodiment is described by taking two sheet noses 413 as an example. The two sheet noses 413 are arranged in parallel up and down and parallel to the sheet body 411, and the sheet nose 413 located at the bottom is longer than the sheet nose 413 located at the top.

[0030] When the woven fabric has two yarn loops of different heights, the yarn hanging parts 414 on the two sheet noses 413 respectively hang the two yarn loops of different heights. After the yarn hanging parts 414 hang the yarn loops, the corresponding upper triangle drives the cutter 42 to cut off the two yarn loops at the same time. In addition, two sheet noses 413 of different heights can also correspond to two yarn loops of different heights, and the yarn loops of corresponding heights can be cut off, so the range of fabric applications is also wider.

[0031] The yarn hanging part 414 includes a groove arranged near the end of the blade nose 413, and the groove is arranged as a slope toward the tail end of the blade nose 413, and the slope is arranged from high to low along the tail end of the blade nose 413 toward the front end of the blade nose 413. The groove is arranged as a slope toward the tail end of the blade nose 413, and the yarn loop enters the groove along the slope, so that the yarn loop enters the groove easily, thereby improving the success rate of cutting the loop.

[0032] The knitting needle 2 is controlled by the lower triangle to move along its trajectory. The jacquard assembly 3 comprises a connecting needle 32 connected to the knitting needle 2 and a jacquard piece 31 connected to the connecting needle 32. The jacquard piece 31 is controlled by a selector to weave a corresponding pattern. Example

[0033] Reference Figure 3 The difference between Example 2 and Example 1 is that the end of the yarn hanging portion 414 forms a hook shape along a trajectory from the top to the tail, and the hook-shaped yarn hanging portion 414 can easily hang on the yarn loop, thereby improving the success rate of cutting the loop.

[0034] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model.
