Description

Technical Field

[0001] This utility model relates to the field of rapier loom technology, and in particular to a rapier loom with a shock-absorbing structure. Background Technology

[0002] Our company's earlier application for the space reduction structure of the swing shaft and rocker shaft (patent number 202321390919.7) typically includes a fixed seat at the main rod position. The fixed seat restricts the rocker shaft, ensuring its stable rotation.

[0003] However, during use, the reverse force of the rocker shaft driving the swing shaft acts on the fixed seat, which makes the connection between the fixed seat and the main rod prone to loosening, and also increases the generation of noise. This problem has long plagued technicians in the industry. Utility Model Content

[0004] The purpose of this invention is to provide a rapier loom with a shock-absorbing structure.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rapier loom with a shock-absorbing structure, including a frame, a main rod arranged between the frames, a rocker shaft rotatably arranged on the frame in front of the main rod, a fixing part arranged on the main rod by vertical bolts, a rotating frame arranged in front of the fixing part by horizontal bolts, the rocker shaft arranged in the rotating frame, and a shock-absorbing pad arranged between the fixing part and the rotating frame.

[0006] The shock-absorbing pad is further configured with multiple vertical strip-shaped air layers inside, the cross-section of which is an arc shape that expands to both sides.

[0007] The device is further configured such that: the front side of the fixing part is provided with an upward sloping slope, and the shock-absorbing pad is provided with a corresponding front sloping slope on the side opposite to the sloping slope.

[0008] The air layer is further configured to have a structure that is larger at the top and smaller at the bottom.

[0009] The rotating frame is further configured such that: the rear end body includes a rear end body, a rear end arc block is integrally provided on the rear end body, a front end arc block is provided at the front end of the rear end arc block, and transverse bolts are sequentially passed through the front end arc block, the rear end arc block, the shock-absorbing pad and the rear end body.

[0010] Further configuration: a transverse groove for the upper edge of the main rod is provided at the lower position of the rear end body, and an extension section is provided at the bottom of the fixing part, with vertical bolts fixed downwards on the extension section.

[0011] In summary, the present invention has the following beneficial effects: by setting a shock-absorbing pad with a front slope between the fixed part and the rotating frame, it can absorb shock during the process of the fixed part being impacted by an upward force and pushed by a downward force, and achieve the effect of reducing noise.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] A rapier loom with a shock-absorbing structure includes a frame 1, with a main rod 2 positioned between the frames 1. The main rod 2 has a conventional transverse U-shaped cross-section. A rocker shaft 3 is rotatably mounted on the frame 1 in front of the main rod 2, and the rocker shaft 3 is driven to rotate by a drive motor located on the outside of the frame 1. A swing shaft is also located on one side of the frame 1, and the rocker shaft 3 drives the swing shaft to swing via a conventional structure.

[0016] A fixing part 4 is provided on the main rod 2, and the fixing part 4 is fixed to the main rod 2 by vertical bolts 5. A rotating frame 6 is provided on the front side of the fixing part 4, and the rocker shaft 3 is set in the rotating frame 6 for rotation.

[0017] A shock-absorbing pad 7 is provided between the fixed part 4 and the rotating frame 6. Multiple vertical strip-shaped air layers 8 are provided within the shock-absorbing pad 7, each air layer 8 having a small channel connecting to the outside. When pressure is applied, some gas can be discharged; when the pressure is released, a small amount of gas can return to the air layer 8. The cross-section of the air layer 8 is an arc shape 9 that expands to both sides. An upward-facing slope 10 is provided on the front side of the fixed part 4, and a corresponding front slope 11 is provided on the side of the shock-absorbing pad 7 opposite to the slope 10.

[0018] When the rocker arm 3 drives the swing arm, the fixed part 4 is subjected to a counterforce that changes in a circular tangential direction. However, the forces are greatest when it receives pressure from the upward angle and pulling force from the downward angle. These two maximum forces make the fixed part 4 prone to vibration and noise. The cooperation of the inclined slope 10 and the front inclined slope 11 can largely absorb the impact of the upward force and the pushing force of the downward force on the fixed part 4, thereby reducing noise.

[0019] Among them, the air layer 8 has a structure that is larger at the top and smaller at the bottom. The air layer 8 can play the role of gas shock absorption, and the structure that is larger at the top and smaller at the bottom can buffer the pressure from the oblique upward on the fixing part 4, thereby achieving the effect of buffering and shock absorption and increasing stability.

[0020] The rotating frame 6 includes a rear end body 12, on which a rear end arc block 13 is mounted. A front end arc block 14 is fixed to the front end of the rear end arc block 13 by bolts. A through hole is provided on the front side of the front end arc block 14, extending to the rear end arc block 13 and the rear end body 12. The bolt passes through the through hole of the front end arc block 14 and sequentially through the front end arc block 14, the rear end arc block 13, the shock-absorbing pad 7, and the rear end body 12, thereby achieving connection and fixation on the front end arc block 14, the rear end arc block 13, the shock-absorbing pad 7, and the rear end body 12. When the bolt passes through the shock-absorbing pad 7, the inner wall of the through hole of the shock-absorbing pad 7 can have threads, thereby making the bolt and the shock-absorbing pad 7 more tightly connected, and the shock-absorbing pad 7 can also achieve a vibration damping effect on the bolt.

[0021] A transverse groove 16 is provided below the fixing part 4 for the upper edge of the main rod 2 to be inserted. An extension section 17 is provided at the bottom of the fixing part 4, extending to the inner wall of the main rod 2 in the vertical direction. Vertical bolts on the fixing part 4 are fixed downward to the extension section 17, thereby increasing the stability of the overall structure.

[0022] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
