Description

Technical Field

[0001] This utility model relates to the field of air-jet loom technology, and in particular to a scissor holder for an air-jet loom. Background Technology

[0002] Air-jet looms are shuttleless looms that use jet airflow to pull the weft yarn through the shed. The working principle is to use air as the weft-introducing medium, and the compressed airflow generated by the jet will generate frictional traction force on the weft yarn to pull it through the shed. The jet generated by the airflow achieves the purpose of weft introduction.

[0003] In the existing technology, a scissor holder for an air-jet loom with application number CN202422410282.4 is described. This application uses a guide rail, with the upper end of the scissor holder fixedly connected to the guide rail. A first limiting groove is provided in the middle of the upper surface of the guide rail. A screw is rotatably connected to the middle of the first limiting groove. A second limiting groove is provided in the lower end of both ends of the guide rail before and after the first limiting groove. The lower end of the mounting plate is inserted into the first limiting groove. Two rectangular limiting parts slide into the two second limiting grooves respectively. The lower end of the mounting plate can slide to one side inside the first limiting groove. When the lower end of the mounting plate slides along the inside of the first limiting groove, it drives the two rectangular limiting parts to slide inside the two second limiting grooves. The two rectangular limiting parts support the lower end of the mounting plate to ensure the stability of the sliding of the mounting plate. However, the scissor assembly is relatively fixed and not easy to disassemble. When the blade of the scissor assembly wears and becomes dull, it is easy to produce burrs when cutting the fabric, thus affecting the quality of the fabric. Utility Model Content

[0035] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] Reference Figure 1-5 A scissor holder for an air-jet loom includes a frame 1, an adjustment assembly 2, a shearing assembly 3, a mounting assembly 4, and a locking assembly 5. The adjustment assembly 2 is mounted on the upper end of the frame 1, the shearing assembly 3 is mounted on the front end of the adjustment assembly 2, and is used for shearing the fabric. The mounting assembly 4 is installed inside the shearing assembly 3 and is used for disassembling and assembling the internal structure of the shearing assembly 3. The locking assembly 5 is installed inside the adjustment assembly 2 and is used to ensure the stability of the adjustment assembly 2 during use.

[0037] Reference Figure 1 , Figure 2 and Figure 3The adjusting assembly 2 includes: a movable platform 201 slidably connected to the upper end of the frame 1; an adjusting platform 202 fixedly installed on the upper end of the movable platform 201; a lead screw 203 rotatably connected inside the adjusting platform 202; a slider 204 rotatably connected to the outside of the lead screw 203; a scissor seat 205 fixedly installed on the upper end of the slider 204; fixed blocks 206 fixedly installed on the front and rear sides of the upper end of the adjusting platform 202; a sliding rod 207 fixedly installed between the fixed blocks 206; a stabilizing block 208 slidably connected to the outside of the sliding rod 207; and the stabilizing block 208 welded to the scissor seat 205 on the side near the central axis. The cutting assembly 3 includes: a rotating shaft 301 rotatably connected to the front end of the scissor holder 205; an installation ring 302 fixedly installed on the outside of the rotating shaft 301; a movable blade 303 slidably connected to the outside of the rotating shaft 301 at the front end of the installation ring 302; a groove 304 at the front end of the installation ring 302; a locking block 305 fixedly installed at the rear end of the movable blade 303; a locking nut 306 threadedly connected to the front end of the rotating shaft 301; a rubber pad 307 bonded to the rear end of the locking nut 306; a receiving block 308 fixedly installed at the lower end of the scissor holder 205; and a fixed blade 309 clamped at the upper end of the receiving block 308.

[0038] In this invention, when the position of the scissor holder 205 needs to be adjusted, the motor inside the adjusting table 202 is started. The motor drives the lead screw 203 to rotate, thereby causing the slider 204 to slide inside the adjusting table 202. As the slider 204 slides, the scissor holder 205 follows, thus adjusting the position of the scissor holder 205. At the same time, when the scissor holder 205 slides, the stabilizing block 208 slides along the sliding rod 207 between the fixed blocks 206, ensuring the stability of the sliding of the scissor holder 205 and preventing positional deviation of the scissor holder 205 from affecting the cutting effect. This facilitates the adjustment of the position of the scissor holder 205 according to the position of the weft yarn, meeting the cutting needs of different fabrics. The movable blade 303 is designed for disassembly. When it is necessary to disassemble and replace the movable blade 303, first loosen the locking nut 306 to disengage the rubber pad 307 from the movable blade 303, and then unscrew the locking nut 306 from the rotating shaft 301. Then slide the movable blade 303 forward on the outside of the rotating shaft 301, so that the locking block 305 on the movable blade 303 disengages from the locking groove 304 and the movable blade 303 disengages from the mounting ring 302, thereby disassembling the movable blade 303. This facilitates the disassembly, replacement, or maintenance of the movable blade 303, while ensuring the stability of the movable blade 303 after installation.

[0039] Reference Figure 1 , Figure 4 and Figure 5The mounting component 4 includes: a reinforcing block 401 fixedly mounted on the lower end of the fixed blade 309; a docking block 402 fixedly mounted on the right side of the front end of the fixed blade 309; a docking groove 403 opened in the middle of the front end of the receiving block 308; and threaded posts 404 fixedly mounted on the left and right sides of the docking block 402 at the front end of the fixed blade 309. The locking component 5 includes: an adjusting nut 501 threadedly connected to the left and right sides of the movable table 201; a locking plate 502 rotatably connected to the adjusting nut 501 near the central axis; and slots 503 opened on the left and right sides of the frame 1.

[0040] In this invention, the fixed blade 309 is also detachable. To disassemble the fixed blade 309, loosen the nut on the threaded post 404 to release it from contact with the receiving block 308. Then, pull the fixed blade 309 upwards to disengage the mating block 402 from the mating groove 403, thus facilitating disassembly. This design prevents wear on the fixed blade 309 from affecting its ability to cut the fabric. During installation, the right side of the reinforcing block 401 is tightly fitted against the receiving block 308 to ensure the fixed blade 309... To ensure structural strength, when the position of the movable table 201 needs to be adjusted, the adjusting nut 501 is turned to slide the locking plate 502, releasing the locking plate 502 from its contact with the inside of the slot 503, thereby releasing the lock on the movable table 201. Then, the movable table 201 is slid to the appropriate position, and the adjusting nut 501 is turned again to make the locking plate 502 fit tightly against the slot 503, thus locking the movable table 201. This allows the position of the movable table 201 to be adjusted according to the usage requirements of the air-jet loom, thereby adjusting the position of the shearing seat 205 and improving the stability of the shearing seat 205 during use.
