Description

Technical Field

[0001] This utility model belongs to the field of rapier stabilization for rapier looms, and specifically relates to a rapier stabilization structure for rapier looms. Background Technology

[0002] As a key piece of equipment in the textile industry, the stable operation of the rapier system in rapier looms directly affects fabric quality and production efficiency. The rapier needs to maintain precise trajectory control during high-speed reciprocating motion to ensure the stability of the weft insertion process. With the development of textile technology, the variety of fabrics is becoming increasingly rich, and the requirements for the operating speed and precision of looms are constantly increasing. The dynamic load borne by the rapier structure is also increasing. Against this background, a rapier stabilization structure for rapier looms has emerged to provide reliable support for the rapier system and help the loom operate efficiently and stably.

[0003] In the existing technology, the rapier stabilization structure of the rapier loom has the basic support function, which can ensure the basic operational stability of the rapier. Its structural design is mature, and the rapier and the loom are stably assembled through conventional limiting and connecting parts. It is suitable for the production needs of most conventional fabrics, the installation and maintenance process is simple, and related parts are easy to obtain. It can meet the basic stability requirements of the daily operation of the loom and provide a basic guarantee for the continuity of textile production.

[0004] Although the existing technology has a simple installation and maintenance process and readily available parts, which can meet the basic stability requirements for the daily operation of the loom and provide a basic guarantee for the continuity of textile production, the rapier stabilization structure of the existing rapier loom is mostly a rigid fixed connection. The components are tightly assembled and lack convenient disassembly design. When replacing worn parts, multiple fixed structures need to be disassembled, which is cumbersome and time-consuming. This inconvenient disassembly design leads to low maintenance efficiency and makes it difficult to quickly replace parts, affecting the continuous operation of the loom and the production progress. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a rapier stabilization structure for a rapier loom to solve the problem of rapier stabilization in rapier looms.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A rapier stabilizing structure for a rapier loom includes an outer shell and an assembly plate. A reinforcing rod is sleeved inside the outer shell. Limiting shells are sleeved around both ends of the outer shell. A snap-fit ​​shell is integrally formed at the end of the limiting shell away from the outer shell. Mounting posts are integrally formed at both ends of the reinforcing rod. Snap-fit ​​components are provided on both sides inside the mounting posts, and these components snap-fit ​​onto the snap-fit ​​shells. A connecting post is threadedly connected to the end of the mounting post away from the reinforcing rod. A buffer component is fixedly installed at the center of the upper end of the assembly plate. The upper end of the buffer component is sleeved at the connection between the mounting post and the connecting post. A connecting frame is fixedly connected to the end of the buffer component away from the limiting shell. A stabilizing plate is integrally formed on the upper end of the connecting frame, and the stabilizing plate is sleeved around the outer ring of the connecting post.

[0008] As a preferred technical solution, the snap-fit ​​assembly includes a slot, a snap-fit ​​spring, a snap-fit ​​block, and a snap-fit ​​groove. The mounting post has slots at both the upper and lower ends. A snap-fit ​​spring is fixedly installed inside the slot. A snap-fit ​​block is fixedly installed at the end of the snap-fit ​​spring away from the slot. The snap-fit ​​shell has snap-fit ​​grooves at both the upper and lower ends. The snap-fit ​​block is snap-fitted and installed inside the snap-fit ​​groove.

[0009] As a preferred technical solution, the reinforcing rod has limiting grooves at both the upper and lower ends of its outer ring, and the outer shell body has limiting plates integrally formed at both the upper and lower ends, with the limiting plates inserted into the limiting grooves.

[0010] As a preferred technical solution, limit holes are opened on both sides of the inner side of the reinforcing rod, and limit rods are fixedly installed on both sides of the limit shell near the reinforcing rod, and the limit rods are slidably installed inside the limit holes.

[0011] As a preferred technical solution, the end of the mounting column away from the reinforcing rod has an internal threaded groove, and the end of the connecting column near the reinforcing rod is fixedly installed with a lead screw, which is threaded into the internal threaded groove.

[0012] As a preferred technical solution, the buffer assembly includes a buffer seat, a buffer groove, a buffer spring, and a buffer plate. The buffer seat has a buffer groove inside its upper end. Buffer springs are fixedly installed on both sides inside the buffer groove. A buffer plate is fixedly installed at the end of the buffer spring away from the buffer groove. The bottom of the buffer plate is slidably installed inside the buffer seat.

[0013] As a preferred technical solution, the assembly plate has assembly holes on both sides inside, the limiting shell has a connecting groove inside, and the mounting column slides inside the limiting shell through the connecting groove.

[0014] In summary, the present invention has the following main advantages:

[0015] First, when it is necessary to replace a part, press the locking block inside the locking shell to compress the locking spring and release it from the slot, which will release the locking between the mounting post and the limiting shell. Rotate the connecting post in the opposite direction to disengage the lead screw from the internal thread groove, which will separate the connecting post and the mounting post. Then slide the limiting rod out along the limiting hole to disassemble the limiting shell and the shell body. The modular design of each part means that the replacement of a single part does not require disassembling the entire structure, which greatly simplifies the maintenance steps.

[0016] Secondly, the connection rigidity is further strengthened by the thread preload, forming an integrated transmission chain of reinforcing rod, mounting column, and connecting column, ensuring seamless power transmission. The dynamic stability function is achieved by the buffer assembly and the stabilizing structure. When the loom is running, the radial vibration generated by the high-speed reciprocating motion of the rapier is transmitted to the stabilizing plate through the connecting column. The stabilizing plate transmits the force to the buffer assembly connected to the connecting frame. After being stressed, the buffer plate slides along the buffer groove of the buffer seat, compressing the buffer springs on both sides. The springs absorb the vibration energy through elastic deformation, converting the instantaneous impact force into a slowly released elastic force, preventing the vibration from being transmitted to the assembly plate and the loom frame. At the same time, the continuous insertion of the limiting plate and the limiting groove, and the sliding fit of the limiting rod and the limiting hole, always maintain the straightness of the rapier's movement trajectory, preventing weft insertion errors caused by radial offset.

Detailed Implementation

[0023] Example

[0024] refer to Figures 1-5 This embodiment of a rapier stabilizing structure for a rapier loom includes an outer shell 1 and an assembly plate 9. A reinforcing rod 11 is sleeved inside the outer shell 1. Limiting shells 2 are sleeved on the outer rings of both ends of the outer shell 1. A snap-fit ​​shell 21 is integrally formed at the end of the limiting shell 2 away from the outer shell 1. Mounting posts 15 are integrally formed at both ends of the reinforcing rod 11. Snap-fit ​​components 3 are provided on both sides inside the mounting posts 15. The snap-fit ​​components 3 are snapped into the snap-fit ​​shell 21. A connecting post 6 is threadedly connected to the end of the mounting post 15 away from the reinforcing rod 11. A buffer component 27 is fixedly installed at the center of the upper end of the assembly plate 9. The upper end of the buffer component 27 is sleeved at the connection between the mounting post 15 and the connecting post 6. A connecting frame 8 is fixedly connected to the end of the buffer component 27 away from the limiting shell 2. A stabilizing plate 4 is integrally formed on the upper end of the connecting frame 8. The stabilizing plate 4 is sleeved on the outer ring of the connecting post 6.

[0025] refer to Figures 3 to 4 The snap-fit ​​assembly 3 includes a slot 25, a snap-fit ​​spring 24, a snap-fit ​​block 26, and a snap-fit ​​groove 22. The mounting post 15 has slots 25 at both the upper and lower ends. The snap-fit ​​spring 24 is fixedly installed inside the slots 25. The snap-fit ​​block 26 is fixedly installed at the end of the snap-fit ​​spring 24 away from the slot 25. The snap-fit ​​housing 21 has snap-fit ​​grooves 22 at both the upper and lower ends. The snap-fit ​​block 26 is snapped into the groove 22. When it is necessary to replace the part, press the snap-fit ​​block 26 in the snap-fit ​​housing 21 to compress the snap-fit ​​spring 24 and release it from the groove 22, thereby releasing the lock between the mounting post 15 and the limiting housing 2. Rotate the connecting post 6 in the opposite direction to make the lead screw 23 disengage from the internal thread groove 16, thereby separating the connecting post 6 from the mounting post 15. Then slide the limiting rod 20 out along the limiting hole 12 to disassemble the limiting housing 2 and the housing body 1. The modular design of each component allows the replacement of a single component without disassembling the entire structure, greatly simplifying the maintenance steps.

[0026] refer to Figure 2 The reinforcing rod 11 has limiting grooves 13 at both the upper and lower ends of its outer ring. The outer shell body 1 has a limiting plate 14 integrally formed at both the upper and lower ends of its inner ring. The limiting plate 14 is inserted into the limiting groove 13. The limiting plate 14 on the inner wall of the outer shell body 1 is precisely inserted into the limiting groove 13 of the outer ring of the reinforcing rod 11. The circumferential limiting prevents the reinforcing rod 11 from rotating relative to the outer shell body 1, thus forming a rigid combination of the outer shell body 1 and the reinforcing rod 11.

[0027] refer to Figures 1 to 2Limiting holes 12 are opened on both sides of the inner end of the reinforcing rod 11. Limiting rods 20 are fixedly installed on both sides of the end of the limiting shell 2 close to the reinforcing rod 11. The limiting rods 20 are slidably installed inside the limiting holes 12. The limiting shell 2 is sleeved on the outer ring of both ends of the shell body 1. The limiting rods 20 of the limiting shell 2 close to the reinforcing rod 11 are inserted into the limiting holes 12 at the end of the reinforcing rod 11. The coaxiality of the shell body 1 and the limiting shell 2 is ensured by axial sliding constraint.

[0028] refer to Figures 2 to 3 The mounting post 15 has an internal threaded groove 16 at the end away from the reinforcing rod 11. The connecting post 6 has a lead screw 23 fixedly installed at the end near the reinforcing rod 11. The lead screw 23 is threaded into the internal threaded groove 16. By rotating the connecting post 6, the lead screw 23 at its end is screwed into the internal threaded groove 16 of the mounting post 15. The thread preload further strengthens the connection rigidity, forming an integrated transmission chain of reinforcing rod 11, mounting post 15 and connecting post 6, ensuring seamless power transmission.

[0029] refer to Figure 5 The buffer assembly 27 includes a buffer seat 7, a buffer groove 18, a buffer spring 17, and a buffer plate 5. The buffer seat 7 has a buffer groove 18 inside its upper end. Buffer springs 17 are fixedly installed on both sides inside the buffer groove 18. A buffer plate 5 is fixedly installed on the end of the buffer spring 17 away from the buffer groove 18. The bottom of the buffer plate 5 is slidably installed inside the buffer seat 7. The buffer assembly 27 works together with the stabilizing structure. When the loom is running, the radial vibration generated by the high-speed reciprocating motion of the rapier is transmitted to the stabilizing plate 4 through the connecting column 6. The stabilizing plate 4 transmits the force to the buffer assembly 27 connected to the connecting frame 8. After being subjected to force, the buffer plate 5 slides along the buffer groove 18 of the buffer seat 7, compressing the buffer springs 17 on both sides. The springs absorb the vibration energy through elastic deformation, converting the instantaneous impact force into a slowly released elastic force, thus preventing the vibration from being transmitted to the assembly plate 9 and the loom frame.

[0030] refer to Figure 3 The assembly plate 9 has assembly holes 10 on both sides inside, and the limiting shell 2 has a connecting groove 19 inside. The mounting column 15 slides inside the limiting shell 2 through the connecting groove 19, which can effectively fix and install it with the loom frame.

[0031] Operating principle and advantages: In use, the outer shell 1 serves as the basic load-bearing structure. When the reinforcing rod 11 is internally fitted, the limiting plate 14 on the inner wall of the outer shell 1 is precisely inserted into the limiting groove 13 on the outer ring of the reinforcing rod 11. This circumferential limiting prevents relative rotation between the reinforcing rod 11 and the outer shell 1, forming a rigid combination of the outer shell 1 and the reinforcing rod 11, thus improving the overall deformation resistance of the rapier. Subsequently, the limiting outer shell 2 is fitted onto the outer rings at both ends of the outer shell 1. The limiting rod 20 of the limiting outer shell 2, which is close to the reinforcing rod 11, is inserted into the limiting hole 12 at the end of the reinforcing rod 11. The coaxiality of the outer shell 1 and the limiting outer shell 2 is ensured through axial sliding constraint. To establish a benchmark for subsequent component assembly, the connection and fixing process relies on the cooperation of the snap-fit ​​assembly 3 and the threaded structure. After the mounting posts 15 at both ends of the reinforcing rod 11 are inserted into the connecting grooves 19 of the limiting housing 2, the engaging springs 24 in the slots 25 inside the mounting posts 15 push the snap-fit ​​blocks 26 out. The snap-fit ​​blocks 26 precisely engage in the slots 22 of the snap-fit ​​shells 21 at the ends of the limiting housing 2, achieving rapid locking between the mounting posts 15 and the limiting housing 2. At the same time, the connecting post 6 is rotated, causing the lead screw 23 at its end to screw into the internal thread groove 16 of the mounting post 15. The thread preload further strengthens the connection rigidity, forming an integrated transmission system of the reinforcing rod 11, mounting posts 15, and connecting posts 6. The chain ensures seamless power transmission. The dynamic stabilization function is achieved by the buffer assembly 27 and the stabilizing structure. When the loom is running, the radial vibration generated by the high-speed reciprocating motion of the rapier is transmitted to the stabilizing plate 4 through the connecting column 6. The stabilizing plate 4 transmits the force to the buffer assembly 27 connected to the connecting frame 8. After being subjected to force, the buffer plate 5 slides along the buffer groove 18 of the buffer seat 7, compressing the buffer springs 17 on both sides. The springs absorb the vibration energy through elastic deformation, converting the instantaneous impact force into a slowly released elastic force, preventing the vibration from being transmitted to the assembly plate 9 and the loom frame. At the same time, the continuous insertion of the limiting plate 14 and the limiting groove 13, and the sliding of the limiting rod 20 and the limiting hole 12 are also achieved. The dynamic coordination ensures the straightness of the rapier's movement trajectory, preventing weft insertion errors caused by radial offset. The maintenance and disassembly process is designed for ease of use. When a component needs to be replaced, pressing the locking block 26 inside the locking housing 21 compresses the locking spring 24, causing it to exit the locking groove 22, thus releasing the lock between the mounting post 15 and the limiting housing 2. Rotating the connecting post 6 in the opposite direction causes the lead screw 23 to disengage from the internal thread groove 16, separating the connecting post 6 from the mounting post 15. Then, sliding the limiting rod 20 along the limiting hole 12 allows the limiting housing 2 and the housing body 1 to be disassembled. The modular design of each component allows for the replacement of a single component without disassembling the entire structure, greatly simplifying the maintenance steps.
