As shown in fig. 1, the yarn adjusting device comprises a mounting frame 10, wherein the mounting frame 10 is provided with a plurality of yarn adjusting mechanisms, and further, the yarn adjusting mechanism is used for adjusting yarns with various colors.

The yarn adjusting mechanism comprises a yarn clamping assembly 30 and a yarn pushing assembly 20 used in a matching way.

As shown in fig. 1 and 2, the yarn pushing assembly 20 includes a yarn pushing frame 21 slidably connected to the mounting frame 10, and a second cylinder 22 driving the yarn pushing frame 21 to move, wherein the yarn pushing frame 21 is provided with a through hole 23 for receiving the color yarn.

The through hole 23 may be a through hole or a through hole with a notch, so that the end of the dyed yarn can be fixed at the yarn clamping assembly 30, and then the dyed yarn enters the through hole 23 through the notch, thereby facilitating the operation.

As shown in fig. 1 and 3, the yarn clamping assembly 30 includes a cutter bar 31, a cutter sleeve 32 slidably connected to the cutter bar 31, and a first cylinder 33 driving the cutter sleeve 32 to move, the cutter bar 31 is provided with a first groove 34 for receiving the colored yarn from the through hole 23 to pass through, the cutter sleeve 32 is provided with a cutter 35 and a yarn clamping member 36, the yarn clamping member 36 is disposed at an inlet end of the colored yarn on the first groove 34, and the cutter 35 is disposed at an outlet end of the colored yarn on the first groove 34.

The entry and exit ends are defined by the direction of travel of the dyed yarn in the first groove 34 and not by the direction of entry of the entire dyed yarn into the first groove 34.

The working principle of the wire adjusting device is as follows: in the initial state, the dyed yarns pass through the through holes 23, the end parts of the dyed yarns are fixed at the inlet ends of the first grooves 34, the end parts of the dyed yarns are clamped and fixed by the yarn clamping piece 36 and the cutter bar 31, and the yarn pushing frame is positioned at one end, far away from the circular weaving machine, on the stroke.

When color matching is needed, the second air cylinder 22 pushes the yarn pushing frame 21 to move, the yarn pushing frame 21 moves towards the circular weaving machine, then the through hole 23 of the yarn pushing frame drives the color yarn to move towards the circular weaving machine, the crochet needle of the circular weaving machine hooks the color yarn from one side of the yarn pushing frame 21 close to the yarn clamping assembly 30, and then the color yarn is woven on the fabric.

Then, the first cylinder 33 is actuated to rapidly drive the thread clamping member through the entrance end of the first groove 34, so that a gap remains between the thread clamping member 36 and the cutter bar 31, which is the entrance of the first groove 34, thereby releasing the fixing of the end of the dyed yarn, but of course, the fixing of the end of the dyed yarn may be released by driving the dyed yarn by the circular knitting machine.

When the color matching is finished, the second cylinder 22 drives the yarn pushing frame to return, then the through hole 23 drives the color yarn to enter the first groove 34, then the first cylinder 33 acts to drive the cutter sleeve 32 to move towards the side of the first groove 34, so that the yarn clamping piece 36 and the cutter bar 31 clamp and fix the color yarn, meanwhile, the cutter 35 is matched with the outlet end of the first groove 34 to cut off the color yarn, and the color yarn stops supplying yarn to the fabric.

The cutting and holding of the dyed yarn may be performed simultaneously or sequentially. The colored yarns are firstly cut off, the colored yarns are broken, the colored yarns are separated from the first groove 34 and cannot clamp the fixed gap, the colored yarns are firstly clamped, and the colored yarns are easy to move relatively because the colored yarns are not cut off, so that the abrasion of contact parts is accelerated, and the adjustment can be realized according to the actual condition.

In the embodiment, the cylinder is used for driving the yarn pushing assembly 20 and the yarn clamping assembly 30 to act, and the original complex mechanical structure is replaced, so that the yarn adjusting device is simple and compact in structure, few in parts and high in reliability; moreover, the angle between the wire pushing component and the wire clamping component can be manufactured and set at will according to the needs, and the wire pushing component is convenient to apply and popularize; moreover, the actions of the yarn pushing assembly 20 and the yarn clamping assembly depend on the control of the air cylinder, are independent of the cycle of the circular weaving machine, and can be adjusted in color at will; moreover, a plurality of thread adjusting mechanisms can be conveniently arranged, and the simultaneous adjustment of a plurality of color yarns is realized; in addition, the yarn clamping assembly 30 is provided with the cutter 35, so that the yarn clamping and the yarn cutting can be synchronously carried out, and the adjusting time is shortened.

In some embodiments, the yarn pushing assembly 20 can be arranged at the bottom of the yarn clamping assembly 30, and the yarn pushing frame 21 pushes yarns in an obliquely upward direction, so that the yarns can be conveniently pushed at any angle.

In some embodiments, the dyed yarn may be supplied from above the yarn changer, and in order to avoid interference of the dyed yarn with the action of the yarn clamping assembly 30, the mounting frame 10 may be provided with a guide roller for introducing the dyed yarn into the through hole 23, the guide roller being disposed above or obliquely above the yarn clamping assembly 30.

In some embodiments, the moving direction of the yarn pushing frame 21 and the moving direction of the knife sleeve 32 can be offset, and the through hole 23 can move to two sides of the knife bar 31. The through hole 23 can move to the two sides of the cutter bar 31, so that the dyed yarns can conveniently enter the first groove 34, and the clamping, fixing and cutting are convenient.

Of course, in some embodiments, a baffle may be provided, and the baffle moves together with the knife pouch 32 to close the mouth of the first groove 34, so as to prevent the color line from separating from the first groove 34, and achieve the same effect, and the baffle is not shown.

In some embodiments, the yarn pushing frame 21 may be provided with a rod portion 25 connected to the second cylinder 22, the second cylinder 22 is provided with a push rod, and the push rod is provided with a limiting groove 26 for accommodating the rod portion 25, so that the assembly and disassembly of the yarn pushing assembly 20 are facilitated, and a plurality of color matching mechanisms are conveniently arranged at the same time.

In some embodiments, in order to avoid the color yarns from being clamped and fixed due to the color yarn shift, a limiting concave part 38 for accommodating the color yarns can be arranged on one side of the yarn clamping piece 36 away from the knife sleeve 32.

In some embodiments, in order to maintain the clamping force between the yarn clamping member 36 and the knife bar 31, the yarn clamping member 36 may be in a sheet shape, the knife sleeve 32 is provided with a spring piece 37 abutting against the yarn clamping member 36, and the spring piece 37 enables the yarn clamping member 36 to be arranged in close contact with the knife bar 31.
