Description

Technical Field

[0001] The utility model relates to the field of air-jet looms, and particularly to a scissors seat for an air-jet loom. Background Technique

[0002] An air-jet loom is a shuttleless loom that uses a jet of air to draw the weft yarn through the shed. Its working principle is to use air as the weft insertion medium, and the compressed air jet generates frictional traction on the weft yarn to draw it through the shed, achieving the purpose of weft insertion through the jet flow generated by the air jet. This weft insertion method enables the loom to achieve high speed and high output. Among several types of shuttleless looms, the air-jet loom has the highest weaving speed. Due to its reasonable weft insertion method, high weft insertion rate, simple, safe operation, wide variety adaptability, low consumption of machine materials, high efficiency, high speed, and low noise, it has become one of the most promising new types of looms. However, since the air-jet loom adopts the air-jet weft method, its biggest drawback is high energy consumption.

[0003] For example, the authorized announcement number CN 208917429 U discloses an electronic scissors for an air-jet loom, which includes a frame. A scissors seat is arranged on the frame, and a mounting plate perpendicular to the frame is arranged on the scissors seat. A shearing device for shearing the fabric is arranged on the mounting plate. The shearing device includes a fixed blade arranged at one end of the mounting plate and a movable blade rotatably connected to one side of the mounting plate. A rotating mechanism for driving the movable blade to rotate intermittently is arranged on the side of the mounting plate away from the movable blade, and a spring-back mechanism for driving the movable blade to reset is also arranged on the mounting plate. The utility model has the following advantages and effects: Under the action of the rotating mechanism and the spring-back mechanism, the shearing device continuously shears the fabric. When the fabric is pressed against the shearing device, the movable blade and the fixed blade can quickly shear the fabric, reducing the possibility of fabric wrinkles and ensuring the flatness of the cut edge of the fabric, thereby improving the processing quality of the fabric.

[0004] The electronic scissors cut the weft yarn pushed by the pushing mechanism on the air-jet loom. However, in the above technology, the scissors seat and the mounting plate are fixedly connected, which is not convenient for adjusting the horizontal position of the scissors assembly. When the distance between the weft yarn pushed by the pushing mechanism on the air-jet loom and the scissors mechanism is relatively far, the weft yarn cannot be cut. Therefore, there is an urgent need in the market to develop a scissors seat for an air-jet loom to help people solve the existing problems. Content of the Utility Model

Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Please refer to Figures 1-5 , an embodiment provided by the present invention: A scissors seat for an air-jet loom, including a mounting plate 1, a scissors assembly 101 is fixedly connected to the front end of the mounting plate 1, and a driving device 102 for driving the scissors assembly 101 to work is fixedly connected to the rear end face of the mounting plate 1. Rectangular limiting parts 2 are fixedly connected to one side of the lower ends of the front and rear ends of the mounting plate 1. A scissors seat 3 is connected to one side of the lower end of the mounting plate 1. A guide rail 4 is fixedly connected to the upper end of the scissors seat 3. A first limiting chute 401 is arranged in the middle of the upper end face of the guide rail 4. A screw rod 5 is rotatably connected to the middle of the inside of the first limiting chute 401. Second limiting chutes 402 are arranged at the lower ends of the front and rear ends of the first limiting chute 401 inside the guide rail 4. A frame 6 is sleeved and connected to the middle of the scissors seat 3.

[0025] Furthermore, the lower end of the mounting plate 1 is inserted into the inside of the first limiting chute 401, and the two rectangular limiting parts 2 respectively slide into the inside of the two second limiting chutes 402. The lower end of the mounting plate 1 can slide to one side inside the first limiting chute 401. When the lower end of the mounting plate 1 slides along the inside of the first limiting chute 401, it drives the two rectangular limiting parts 2 to slide inside the two second limiting chutes 402. The lower end of the mounting plate 1 is supported by the two rectangular limiting parts 2 to ensure the stability of the sliding of the mounting plate 1.

[0026] Furthermore, a guiding hole 201 is arranged in the middle of the rectangular limiting part 2. A guiding rod 403 is fixedly connected to the middle of the inside of the second limiting chute 402. The guiding rod 403 inside the second limiting chute 402 passes through the guiding hole 201 in the middle of the rectangular limiting part 2. The sliding of the rectangular limiting part 2 inside the second limiting chute 402 is guided by the guiding rod 403 to ensure the stability of the sliding of the rectangular limiting part 2.

[0027] Further, a threaded hole 103 is provided at the lower end of one side of the mounting plate 1. The screw rod 5 is inserted into the threaded hole 103 and threadedly connected. After the mounting plate 1 is fixed to the frame 6 through the scissors seat 3, according to the pushing mechanism, the weft is pushed to the limit distance. By rotating the screw rod 5, the mounting plate 1 is driven to move to one side, and the position of the scissors assembly 101 is adjusted. After the weft is pushed, the scissors assembly 101 can cut the weft, and it is convenient to adjust the position after the scissors assembly 101 is fixed.

[0028] Further, a circular limiting member 404 is fixedly connected to one side of the guide rail 4. The other end of the screw rod 5 extends out of one side of the guide rail 4 and passes through the middle of the circular limiting member 404 and is fixedly connected with a turntable 502. By driving the turntable 502, the screw rod 5 is rotated, and then the mounting plate 1 is moved.

[0029] Further, a limiting ring 501 is fixedly connected to the screw rod 5 inside the circular limiting member 404. When the screw rod 5 rotates, it rotates inside the circular limiting member 404 through the limiting ring 501 to keep the position of the screw rod 5 stable during rotation.

[0030] Further, the scissors seat 3 and the frame 6 are fixedly connected by bolts 301, so that the scissors seat 3 can be disassembled from the frame 6, which is convenient for maintaining and overhauling the scissors assembly 101.

[0031] Working principle: When in use, when the air-jet loom is working, the weft is pushed by the pushing mechanism to the vicinity of the scissors assembly 101. In order to ensure that the scissors assembly 101 can accurately and effectively cut the weft, first, by rotating the turntable 502, the screw rod 5 is driven to rotate in the threaded hole 103. Since the screw rod 5 is threadedly connected to the mounting plate 1, as the screw rod 5 rotates, the mounting plate 1 will smoothly slide on the guide rail 4 along the guidance of the first limiting chute 401 and the second limiting chute 402. At the same time, the guiding hole 201 in the rectangular limiting portion 2 slides along the guiding rod 403 to ensure the stability of the movement of the mounting plate 1. In this way, the horizontal position of the scissors assembly 101 can be flexibly adjusted according to the actual position of the weft pushed by the pushing mechanism to keep an appropriate distance from the weft. After the position of the scissors assembly 101 is adjusted, the scissors assembly 101 is driven by the driving device 102 to work to cut the weft. The whole adjustment process is convenient and fast.
