Description

Technical Field

[0001] This utility model relates to the field of shuttle control technology, specifically to a shuttle control for textile machinery. Background Technology

[0002] The shuttle rod plays a crucial role in textile machinery. It is one of the core components of the shuttle mechanism, responsible for feeding and retrieving the shuttle into and out of the machine, ensuring the stable and precise trajectory of the shuttle. The design and manufacturing quality of the shuttle rod directly affect the operating efficiency of the textile machinery and the quality of the fabric. A search of existing technology (publication number: CN202054985U) reveals "a shuttle rod for a loom, including a shaft hole, a bushing on the shaft hole, a shuttle arm mounted on the bushing, a shuttle slider hole on the shuttle arm, an elastic groove on the bushing communicating with the shaft hole, a weight-reducing groove inside the shuttle arm, and screw holes on both sides of the elastic groove. This utility model has advantages such as a weight-reducing groove inside the shuttle arm, light weight, small size, low cost, and less susceptibility to problems after a period of use, eliminating the need for replacement."

[0003] While existing shuttle rods achieve lightweight design, they still have some shortcomings: Firstly, the lightweight slots in existing shuttle rods, while contributing to overall weight reduction, reduce the mechanical strength of the rod arm. This can lead to deformation of the arm during prolonged mechanical operation, rendering it unusable. Secondly, the elastic slots are secured with threaded holes and bolts, and mechanical vibrations from equipment movement can cause these bolts to loosen. This can result in relative movement of the drive shaft connected to the shuttle rod's drive end, leading to errors in the shuttle rod's swing stroke. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a shuttle rod for textile machinery is provided to solve the problems of reduced mechanical strength and unstable connection during use of existing shuttle rods while achieving weight reduction.

[0005] To achieve the above objectives, a shuttle rod for textile machinery is provided, comprising: a textile shuttle rod, the textile shuttle rod including a drive end, one end of which is connected to a shuttle arm, and the other end of the shuttle arm is connected to a swing end, the drive end including an internal connecting hole, the outer end of which is provided with an elastic connecting block, the elastic connecting block having a threaded hole inside, and a connecting insertion hole in the threaded hole, a limiting rod being inserted into the insertion hole, and a positioning rod being connected to the bottom of the limiting rod, the shuttle arm including grooves on both sides, and shaped holes in the grooves.

[0006] Furthermore, the inner wall of the connecting hole is provided with anti-slip teeth, and there is a gap groove between the elastic connecting blocks, and the gap groove communicates with the connecting hole.

[0007] Furthermore, the threaded hole is formed in one of the elastic connecting blocks, and the other elastic connecting block has a through hole corresponding to the position of the threaded hole, while the outer end of the through hole has a countersunk hole.

[0008] Furthermore, a bolt is screwed into the threaded hole, and the bolt passes through two elastic connecting blocks, with the limiting rod located outside the bolt head.

[0009] Furthermore, a connecting sliding hole is provided on the outer side of the insertion hole, and a slider is slidably connected to the sliding hole, and the positioning rod is inserted into the slider.

[0010] Furthermore, a spring is sleeved on the outer side of the positioning rod, and the spring is located outside the slider, and the inner end of the positioning rod is inserted into the positioning hole opened on the outer wall of the limiting rod.

[0011] Furthermore, a slot is provided on the outer side of the sliding hole and on the outer wall of the elastic connecting block, and a locking block is engaged inside the slot, and the locking block is connected to the inner side of the head of the positioning rod.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By utilizing the grooves on both sides of the shuttle arm and the multiple holes in the grooves, the shuttle arm is made lightweight while maintaining its structural toughness and mechanical strength. This ensures the mechanical strength of the shuttle arm during movement and prevents deformation.

[0014] 2. Utilizing the elastic connecting block and connecting hole included in the drive end, the connecting hole is inserted into the outside of the drive shaft connecting the textile equipment and the shuttle rod. Through bolts and threaded rods, the elastic connecting block is locked and the drive shaft is clamped and fixed through the connecting hole. Then, a limit rod is inserted into the insertion hole, and a positioning rod is inserted into the positioning hole to restrict the up and down movement of the limit rod. At the same time, the limit rod is located outside the bolt, which restricts the bolt from loosening outward, thereby ensuring the connection stability of the shuttle rod.

[0020] Reference Figures 1 to 4 As shown, this utility model provides a shuttle for textile machinery, including: a textile shuttle 1, the textile shuttle 1 including a drive end 2, one end of the drive end 2 being connected to a shuttle arm 3, and the other end of the shuttle arm 3 being connected to a swing end 4, the drive end 2 including an internally opened connecting hole 21, and an elastic connecting block 23 provided at the outer end of the connecting hole 21, and a threaded hole 231 opened inside the elastic connecting block 23, and a communicating insertion hole 232 opened in the threaded hole 231, a limiting rod 24 being inserted into the insertion hole 232, and a positioning rod 25 being connected to the bottom of the limiting rod 24, the shuttle arm 3 including grooves 31 opened on both sides, and a shaped hole 32 opened in the grooves 31.

[0021] As a preferred implementation, by setting the groove 31, the thickness of the shuttle arm 3 is reduced, and at the same time, the shaped hole 32 is used to strengthen the structural toughness of the thinned shuttle arm 3, thereby improving the mechanical strength.

[0022] like Figures 1 to 3In the connection hole 21, the inner wall is provided with anti-slip teeth 22, and a gap groove is provided between the elastic connecting blocks 23, and the gap groove communicates with the connection hole 21. A threaded hole 231 is opened in one of the elastic connecting blocks 23, and the other elastic connecting block 23 has a through hole corresponding to the position of the threaded hole 231. At the same time, a countersunk hole 233 is opened at the outer end of the through hole. A bolt 27 is screwed into the threaded hole 231, and the bolt 27 passes through the two elastic connecting blocks 23. The limiting rod 24 is located outside the head of the bolt 27 and outside the insertion hole 232. A through-hole 234 is provided, and a slider 251 is slidably connected to the through-hole 234. A positioning rod 25 is inserted into the slider 251. A spring 26 is sleeved on the outside of the positioning rod 25, and the spring 26 is located on the outside of the slider 251. The inner end of the positioning rod 25 is inserted into a positioning hole 241 opened on the outer wall of the limiting rod 24. A slot 235 is opened on the outer side of the through-hole 234 and on the outer wall of the elastic connecting block 23. A locking block 252 is locked inside the slot 235 and is connected to the inner side of the head of the positioning rod 25.

[0023] Specifically, after the bolt 27 is connected, the head of the device is in the countersunk hole 233, and the limiting rod 24 is also in the countersunk hole 233 after the connection.

[0024] Specifically, by setting the slot 235 and the block 252, the positioning rod 25 is prevented from rotating and loosening after it is engaged with the limiting rod 24.

[0025] Secondly, when the positioning rod 25 is disassembled from the positioning hole 241, the head of the positioning rod 25 can be pulled from the outside. During the process, the slider 251 squeezes the spring 26 outward until the positioning rod 25 is disengaged from the limiting rod 24. When installing, the limiting rod 24 is installed first, while keeping the positioning hole 241 facing the sliding hole 234, and then the positioning rod 25 is inserted into it.

[0026] In use, the grooves on both sides of the shuttle arm and the multiple holes in the grooves achieve a lightweight effect while maintaining the structural toughness and mechanical strength of the shuttle arm. This ensures the mechanical strength of the shuttle arm during movement and prevents deformation. The elastic connecting block and connecting hole included in the drive end allow the connecting hole to be inserted into the outside of the drive shaft connecting the textile equipment and the shuttle arm. Through bolts and threaded rods, the elastic connecting block is locked and the drive shaft is clamped and fixed through the connecting hole. Then, a limit rod is inserted into the insertion hole, and a positioning rod is inserted into the positioning hole to restrict the up and down movement of the limit rod. At the same time, the limit rod is located outside the bolt to restrict the bolt from loosening outward, thus ensuring the connection stability of the shuttle arm.

[0027] This utility model of a shuttle rod for textile machinery effectively solves the problems of reduced mechanical strength and unstable connection that occur in existing shuttle rods while achieving lightweighting. It achieves lightweighting while maintaining mechanical strength, and avoids the phenomenon of loosening and instability of the shuttle rod caused by mechanical vibration during use.
