Description

Technical Field

[0001] This utility model relates to the field of high-speed air-jet loom technology, and in particular to a waste selvage yarn scissor device for a high-speed air-jet loom. Background Technology

[0002] Air-jet looms are shuttleless looms that use a jet of air to guide the weft yarn through the shed. The working principle utilizes air as the weft insertion medium; the compressed air jet creates frictional traction on the weft yarn, pulling it through the shed. The jet of air achieves the purpose of weft insertion. Due to its rational weft insertion method, high weft insertion rate, simple and safe operation, wide adaptability to various fabric types, low material consumption, high efficiency, high speed, and low noise, air-jet looms have become one of the most promising new types of looms.

[0003] Waste selvage yarn is an inevitable byproduct of air-jet loom operation. To ensure fabric quality, a yarn shear is typically installed. Therefore, a waste selvage yarn shearing device for high-speed air-jet looms is proposed to address this issue. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waste selvage cutting device for high-speed air-jet looms.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A waste selvage yarn shearing device for a high-speed air-jet loom includes a sleeve. A mounting bracket is fixedly installed on the outer wall of the sleeve by bolts. A fixed blade handle is fixedly installed on the lower end of the outer wall of one end of the sleeve. The fixed blade handle is L-shaped. A fixed blade seat is fixedly installed on the outer side of the vertical section of the fixed blade handle. A strip-shaped through hole is opened on the upper end of the outer wall of the other end of the sleeve. A moving part is slidably installed inside the strip-shaped through hole. A movable blade handle is fixedly installed on the outer side of the movable part. The end of the movable blade handle is arc-shaped. A movable blade is fixedly installed on the inner end of the movable blade handle. A folding plate is fixedly connected to the inner side of the movable part. A reciprocating cylinder is fixedly installed on one end of the sleeve. The movable end of the reciprocating cylinder is fixedly connected to the folding plate.

[0006] Preferably, both the fixed tool holder and the movable tool holder are rotatably equipped with guide rollers on their outer sides.

[0007] Preferably, the fixed tool holder has a V-shaped groove in the middle.

[0008] Preferably, two limiting grooves are formed on the outer wall of the other end of the sleeve, and the two limiting grooves are respectively located at the top and bottom of the strip-shaped through hole.

[0009] Preferably, the four corners of the inner side of the movable component are fixedly provided with sliding columns, and the two sliding columns in each row are slidably sleeved with the limiting sliding groove.

[0010] Preferably, the cross-section of the movable blade is L-shaped.

[0011] Preferably, the folding plate is slidably sleeved with the inner walls of the four sides of the sleeve.

[0012] The beneficial effects of this utility model are as follows: This utility model proposes a waste selvage cutting device for a high-speed air-jet loom. It comprises a fixed handle and a fixed blade holder, a moving component, a movable handle and a movable blade, and a reciprocating cylinder, all arranged around a sleeve. The fixed handle is L-shaped, the fixed blade holder has a V-shaped groove in the middle, the movable handle has an arc-shaped end, and the movable blade has an L-shaped cross-section. The reciprocating cylinder drives the movable handle to move along a strip-shaped through-hole. As the movable handle moves, the movable blade engages in the V-shaped groove of the fixed blade holder, thus cutting off the waste selvage. Guide rollers, rotatably mounted on the outer sides of both the fixed and movable handles, promptly convey the waste selvage.

[0013] This utility model proposes a waste selvage yarn shearing device for a high-speed air-jet loom. The device uses a folding plate that slides and engages with the inner walls of the four sides of the sleeve to reduce dust and waste selvage yarn from falling into the sleeve. Two limiting grooves are provided on the outer wall of the other end of the sleeve, located at the top and bottom of the strip-shaped through hole, respectively. Two sliding columns in each row are slidably engaged with the limiting grooves, so that the moving part moves along the strip-shaped through hole and the two limiting grooves as the reciprocating cylinder pushes the folding plate. This improves the stability of the moving part's repeated horizontal displacement, thereby stabilizing the displacement of the movable handle and the movable blade. Attached Figure Description
