Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a weft yarn processing system for a loom. Background Art

[0002] Weaving looms primarily include rapier looms, air jet looms, water jet looms, and projectile looms. Rapier looms use a rigid or flexible rapier head and belt to clamp and guide the weft yarn. In addition to being suitable for weaving plain, twill, satin, and textured fabrics, rapier looms are also more convenient for weaving wide wefts, making them suitable for producing multi-color wide weft fabrics, yarn-dyed, double-layer fleece, terry, and decorative fabrics. Carbon fiber production requires weft insertion. Traditional looms typically use hooks to hold the ends of the weft yarn during the weft insertion process. However, the weft yarn becomes narrower at the hooked portion, resulting in uneven surface density and a tendency to fuzz, impacting product quality. Summary of the Invention

[0050] The pressing mechanism is used to press the rear end of the upper clamp 311 to tilt the front end of the upper clamp 311 .

[0051] The rapier head 31 is pushed to the clamping position by the rapier belt 32, and the pressing mechanism presses the upper clamp 311, so that the front end of the upper clamp 311 is tilted, and the weft yarn is placed between the upper clamp 311 and the lower clamp 312. The reset spring 313 resets the upper clamp 311, so that the weft yarn is clamped between the upper clamp 311 and the lower clamp 312, and the weft yarn is tightened by the elastic plates 314 on the upper clamp 311 and the lower clamp 312. The rapier head 31 is pulled by the rapier belt 32 to insert the weft.

[0052] like Figure 5~Figure 6 As shown, the pressing mechanism includes: a pressing cylinder 33, a pressing plate 3425, a pressing connecting rod 35 and a pressing head 36.

[0053] The downward pressing link 35 is rotatably connected to the downward pressing plate 3425, and the output end of the downward pressing cylinder 33 is rotatably connected to one end of the downward pressing link 35. The downward pressing cylinder 33 is used to drive the downward pressing link 35 to rotate, and the other end of the downward pressing link 35 is connected to the downward pressing head 36, and the downward pressing head 36 is used to press the rear end of the upper clamp 311.

[0054] The pressing cylinder 33 pushes the pressing link 35 to rotate, so that the pressing head 36 at one end of the pressing link 35 presses the upper clamping head 311, causing the front end of the upper clamping head 311 to tilt up.

[0055] like Figure 5~Figure 6 As shown, the shearing assembly 4 includes: a shearing cylinder 41, a dynamic shearing plate 42 and a static shearing plate 43;

[0056] The movable shear plate 42 and the static shear plate 43 are rotatably connected. The static shear plate 43 is located below the weft yarn. The output end of the shearing cylinder 41 is connected to one end of the movable shear plate 42 for driving the movable shear plate 42 to rotate and cut the weft yarn.

[0057] The shearing cylinder 41 drives the movable shear plate 42 to rotate, so that the movable shear plate 42 and the static shear plate 43 cut the weft yarn.

The first end of the wire storage box 51 is provided with an opening, and the output end of the exhaust fan 53 is connected to the second end of the wire storage box 51. When the wire pulling assembly 3 pulls the weft yarn outward, the wire storage wheel 52 moves toward the first end of the wire storage box 51, and the exhaust fan 53 creates a pressure difference between the second end and the first end of the wire storage box 51. Under the action of pressure, the wire storage wheel 52 moves toward the second end of the wire storage box 51, so that the wire pay-off assembly 1 provides yarn.

[0060] The yarn released by the pay-off assembly 1 enters the wire storage box 51 from the opening of the wire storage box 51, and the yarn passes around the wire storage wheel 52 and then extends out from the opening of the wire storage box 51. The movement of the wire storage wheel 52 in the wire storage box 51 can change the length of the weft yarn in the wire storage box 51, and the exhaust fan 53 can create a pressure difference at both ends of the wire storage box 51. When the length of the weft yarn in the wire storage box 51 is small, the wire storage wheel 52 moves toward the second end of the wire storage box 51, prompting the pay-off assembly 1 to provide yarn, thereby increasing the length of the yarn in the wire storage box 51.

[0061] like Figures 1 to 4 As shown, the wire storage box 51 is a transparent structure, and the wire storage box 51 is rectangular. The size of the wire storage box 51 is related to the wire storage wheel 52, the yarn and the required length of the stored wire.

[0062] The width of the wire storage box is related to the diameter of the wheel, the length of the wire storage box is related to the length required for wire storage, and the thickness of the wire storage box is related to the width of the yarn. The transparent structure of the wire storage box 51 makes it easy to observe the length of the yarn in the wire storage box 51 during processing, and makes it easy to detect and maintain the wire storage component 5 in time when it is damaged. The placement of the wire storage box 51 is based on the product shape and the required orientation of the product, and can be placed horizontally, vertically or obliquely.

[0063] like Figures 1 to 4 As shown, the pay-off assembly 1 includes: a pay-off frame 11 , a pay-off motor 12 and a pay-off wheel 13 .

[0064] The pay-off motor 12 is arranged on the pay-off frame 11 , and the output end of the pay-off motor 12 is connected to the pay-off wheel 13 , on which the weft yarn is arranged.

[0065] The pay-off motor 12 drives the pay-off wheel 13 to rotate, and the weft yarn on the pay-off wheel 13 is paid off. In this embodiment, a guide wheel is provided on the pay-off frame 11, and the weft yarn is guided to the wire storage box 51 through the guide wheel. The wire storage box 51 is rotatably connected to the pay-off frame 11, so that the wire storage box 51 can rotate according to the tension of the weft yarn, and the outlet direction of the wire storage box 51 is adjusted to make the tension of the weft yarn more stable.

[0066] Above, refer to Figures 1 to 7 The present invention describes a weft yarn processing system for a loom according to an embodiment of the present invention. The wire-releasing component 1 of the present application provides the weft yarn to the wire-clamping component 2. The yarn clamping mechanism fixes the end of the yarn at the clamping station. The wire-pulling component 3 clamps the end of the yarn. The yarn clamping mechanism stops fixing the yarn. The wire-pulling component 3 pulls the weft yarn outward. The yarn clamping mechanism moves to the shearing station. When the wire-pulling component 3 stops pulling the weft yarn, the yarn clamping mechanism fixes the yarn. The shearing component 4 cuts the weft yarn. The yarn clamping mechanism moves the end of the yarn back to the clamping station for the next weft insertion process.

[0067] The single-sided weft insertion system adopted in this application clamps the end of the weft yarn through the wire pulling component 3, so that the weft yarn is laid flat for insertion, avoiding damage or distortion of the weft yarn during insertion, preventing the weft yarn from being scattered and fuzzed during processing, ensuring uniform surface density of the product, and improving production efficiency.
