Description

Technical Field

[0001] This utility model relates to the field of application technology of rapier looms, and specifically to a rapier loom connecting assembly. Background Technology

[0002] Rapier looms are versatile, adaptable, and reliable shuttleless looms. They utilize rigid or flexible rapiers carrying the yarn to transfer it through the weave. In practical applications, they can meet the needs of multi-color wefts, complex patterns, heavy fabrics, and various raw material yarns, making them a mainstay in modern textile production. However, the rapier loom's core internal component—the rapier connecting assembly—generally uses a push-type connecting rod with spring extension for yarn pressing. This method suffers from problems such as hook detachment, unstable transmission response time, excessive wear on the rapier connecting assembly, and a complex structure that is difficult to replace and maintain.

[0032] like Figures 1 to 7As shown, a rapier loom receiving assembly is characterized by: including a mounting base 1 and a yarn hooking device 3; a transmission rod device 2 is provided inside the mounting base 1; a fixed housing 4 is provided on the outside of the mounting base 1 near the yarn hooking device 3; the transmission device 2 includes a transmission rod 201, an opening / closing device 202, and a transmission support device 203; the transmission rod 201 near the yarn hooking device 3 has a transmission end 2012, which is cylindrical in shape; the transmission end 2012 is inserted into the inside of the yarn hooking device 3; and the opening / closing device 202 is used to rotate the transmission rod 201 to control the yarn hooking and releasing actions. The transmission support device 203 includes a transmission rod sleeve 2031 and a pressure block 2032. The overall diameter of the transmission rod sleeve 2031 is larger than the overall diameter of the transmission rod 201. The pressure blocks 2032 are vertically distributed and fixedly connected by bolts on the side away from the transmission rod sleeve 2031. The transmission rod sleeve 2031 is laterally snapped into the side of the pressure block 2032, providing rotational support on the sides of the upper and lower pressure blocks 2032. The transmission rod 201 passes through the interior of the opening / closing device 202. Multiple fixing screw holes are provided on one side of the opening / closing device 202, and screws are used to fix and lock the opening / closing device 202 and the transmission rod 201 together. The opening / closing device 202 and the transmission rod 201 rotate coaxially.

[0033] The mounting base 1 is also provided with a transmission rod receiving cavity 102 and a switch mounting cavity 101. The transmission rod receiving cavity 102 and the switch mounting cavity 101 are horizontally connected. The transmission rod receiving cavity 102 is built into the side of the mounting base, which facilitates observation of the usage status of the transmission rod 201. At the same time, the transmission rod receiving cavity 102 protects the transmission rod 201 from damage by external foreign objects. A limiting support cavity 103 is provided above the side of the mounting base 1 near the switch mounting cavity 101. The limiting support cavity 103 is cylindrical in shape, which facilitates the use of bolts to fix the transmission support device 203.

[0034] The yarn hooking device 3 is equipped with an end hook 301 and a transmission support plate 302. The transmission rod 201 is equipped with a transmission support plate 2011. The device is rectangular in shape, with rounded edges on both horizontal sides. The end hook 301 has multiple grooves on its inward-facing side, and the transmission support plate 302 has multiple protrusions on its contact side with the end hook 301, facilitating rapid yarn hooking and unhooking actions between the transmission support plate 302 and the end hook 301. A buffer limiting plate 303 is also provided at the top of the end hook 301. This buffer limiting plate 303 absorbs the impact of the transmission support plate 2011 on the transmission support plate 302 when the transmission support plate 2011 reciprocates vertically within the yarn hooking device 3, and limits its movement, thus extending the service life of the transmission support plate 302. The mounting base 1 has a first base fixing hole 104 and a second base fixing hole 105 on its outer side. The hooking device 3 has a hooking device fixing hole 304 on its lower part on the side away from the end hook 301. The fixed housing 4 has a first housing fixing hole 401, a second housing fixing hole 402, and a third housing fixing hole 403 sequentially arranged on its lower outer side. The first base fixing hole 104 and the first housing fixing hole 401 are fastened together with screws to complete the fixed connection between the mounting base 1 and the fixed housing 4. The hooking device fixing hole 304 and the third housing fixing hole 403 are fastened together with screws to complete the fixed connection between the fixed housing 4 and the hooking device 3. The opening / closing device 202 is manufactured using an integrated metal stamping process, possessing strong durability.

[0035] Operating Principle Explanation: During the disassembly and maintenance of this type of yarn-catching assembly, from an overall external design perspective, the entire assembly adopts a modular design, with each functional module forming a separate integrated unit. The assembly consists of a mounting base 1, a transmission rod device 2, a yarn-hooking device 3, and a fixed housing 4. The fixed housing 4 primarily serves to securely connect the mounting base 1 and the yarn-hooking device 3, providing an interference fit. The transmission rod device 2 works in conjunction with the yarn-hooking device 3 and the mounting base 1. The transmission rod 201 within the transmission rod device 2 controls the transmission and linkage within the yarn-hooking device 3. The opening / closing device 202 controls the rotation amplitude and position of the transmission rod 201, thus controlling the time interval between yarn hooking and unhooking, as well as the speed of the action, meeting the speed requirements under different production conditions. Meanwhile, since the integrated transmission rod 201 is used to control the yarn hooking device 3, the transmission support plate 302 inside the device works in conjunction with the transmission support plate 2011, which allows the gap between the end hook 301 and the transmission support plate 2011 to open and close quickly, realizing the switching between yarn hooking and yarn release. Compared with conventional spring-powered transmission, this greatly reduces transmission delay and also reduces wear between the internal components.
