Description

Technical Field

[0001] This utility model relates to the field of rapier loom technology, specifically a robust frame structure suitable for high-speed rapier looms. Background Technology

[0002] A rapier loom is a textile machine that uses a rapier (a long, thin rod or belt with clips or hooks) to guide the weft yarn from one side of the loom to the other, thus completing the interlacing of warp and weft yarns. It is primarily used for weaving various types of fabrics. Its structure is relatively intuitive, and it is easy to find and handle broken weft yarns. The shuttle changing and weft changing processes are simple, and the skill requirements for operators are relatively low.

[0003] An investigation revealed that a utility model patent discloses a high-stability rapier loom (publication number: CN223202017U), comprising a drive mechanism and a frame. The frame houses a weft insertion mechanism and a beat-up mechanism. The drive mechanism includes a crankshaft mechanism driven by a motor, with a connecting rod connecting the crankshaft mechanism and the beat-up mechanism. The crankshaft mechanism includes a U-shaped crankshaft, a crossbar, and side sections on both sides of the crossbar. The connecting rod includes a connecting rod body and a connecting rod cover. The connecting rod body and the connecting cover form a groove to accommodate the bearing. The bearing is fitted onto the crossbar of the crankshaft. The connecting rod is connected to the bearing via the connecting rod body and the connecting rod cover. The outer ring of the bearing has an annular oil groove on its outer circumference and an oil passage on the outer ring, connecting the annular oil groove to the inner side of the outer ring. The connecting rod has a grease port communicating with the annular oil groove. This utility model provides a high-stability rapier loom that uses a bearing connection between the connecting rod and the crankshaft, facilitating grease application, reducing wear, and improving operational stability.

[0004] Although the aforementioned patent, through the arrangement of components such as the drive mechanism, weft insertion mechanism, and weft raising mechanism, and through the cooperation of these components, can reduce wear and improve the working efficiency of the loom by setting oil channels on the outer ring and continuously replenishing lubricating oil during processing, the traditional rocker arm is a whole symmetrical structure with a large mass and high moment of inertia. During high-speed reciprocating oscillation, it generates a huge periodic inertial torque, which makes the frame vibrate greatly, which is very detrimental to improving the long-term stable operation of the loom.

[0005] Therefore, this utility model provides a robust frame structure suitable for high-speed rapier looms to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a robust frame structure suitable for high-speed rapier looms, such as... Figures 1-4 As shown, a robust frame structure suitable for high-speed rapier looms includes a work frame 1 and a shock-absorbing assembly. The shock-absorbing assembly includes a hollow box 2 installed on the outer wall of the work frame 1.

[0028] The inner wall of the hollow box 2 is fixedly connected to a slide plate 4 by a compression spring 3. A rubber block 5 is fixedly connected to the outer surface of the slide plate 4. An air pipe 6 is rotatably sleeved at the top of the hollow box 2. A dust collection box 7 is fixedly connected to the end of the air pipe 6. A one-way blade 8 is installed on the inner wall of the dust collection box 7. There are several one-way blades 8. An exhaust blade 9 is connected to the outer surface of the hollow box 2 by a damping hinge.

[0029] The shock absorption assembly also includes a snap-on plate 10 that snaps onto the inner wall of the hollow box 2. A filter plate 11 is installed on the inner wall of the hollow box 2, and a snap-on assembly is provided on the outer wall of the air pipe 6.

[0030] Specifically, through the setting of the shock-absorbing component, the various components work together during the operation of the rapier loom. Through the cooperation of the slide plate 4, hollow box 2, one-way blades 8, and exhaust blades 9, the slide plate 4 slides rapidly inside the hollow box 2 due to continuous impacts, thereby mitigating the impact force and vibration. When impacted, the air quickly drives the exhaust blades 9 to rotate on the outer wall of the hollow box 2 through the damping hinge, thereby quickly expelling the compressed air. When the slide plate 4 returns to its original position, the air is drawn inward, which quickly opens the multiple one-way blades 8 at the bottom of the dust collection box 7, thereby quickly sucking in the airborne lint, thus improving the health of the loom's working environment. The buckle plate 10 can open the dust collection box 7 at regular intervals, allowing the filter plate 11 that is clipped to its inner wall to be removed. The filter plate 11 can be kept clean by regular cleaning. This component has a simple structure, strong applicability, and can mitigate the vibration force during equipment operation through active impact, thereby improving the working stability of the loom.

[0031] The snap-fit ​​assembly includes a ratchet 12 fixedly sleeved on the outer wall of the trachea 6, a slide 13 installed on the upper top of the hollow box 2, a pawl 14 slidably connected to the inner wall of the slide 13, and an end plate 15 fixedly connected to the end of the pawl 14.

[0032] The snap-fit ​​assembly also includes a connecting spring 16 fixedly connected to the inner wall of the end plate 15. There are several connecting springs 16, and the ends of the several connecting springs 16 are fixedly connected to the outer wall of the slide 13. The end of the pawl 14 abuts against the outer wall of the ratchet 12.

[0033] Specifically, the angle of the dust collection box 7 can be easily adjusted by setting the snap-fit ​​component, and the dust collection position can be adjusted according to different loom operations. The ratchet 12 and pawl 14 can be used to snap and fix the position of the air pipe 6, thereby maintaining its operational stability.

[0034] A support column 17 is installed at the top of the work frame 1. A pin 18 is rotatably connected to the outer wall of the support column 17. A rotating wheel 19 is rotatably sleeved on the outer wall of the pin 18. A connecting rod 21 is rotatably sleeved on the outer wall of the rotating wheel 19 through a rotating shaft 20.

[0035] The side wall of the work frame 1 is rotatably sleeved with a rocker shaft 23 via a swivel seat 22. The end of the connecting rod 21 is slidably sleeved on the inner wall of the rocker shaft 23. A rubber pad 24 is fixedly connected to the outer wall of the rocker shaft 23. The outer wall of the rubber pad 24 is provided with an anti-slip groove. A reed seat is installed on the inner wall of the rocker shaft 23.

[0036] A drive motor 25 is installed on the outer wall of the work frame 1. A drive wheel 26 is fixedly connected to the output end of the drive motor 25. The outer wall of the drive wheel 26 is connected to the outer wall of the rotating wheel 19 through a synchronous belt 27.

[0037] Specifically, by utilizing the pin 18 and the rotating wheel 19 on the outer wall of the support column 17, the rotating wheel 19, rotating shaft 20, rotating seat 22, connecting rod 21 and rocker shaft 23 can reduce the impact force and vibration of the rocker shaft 23 by using the shock-absorbing material rubber pad 24 to impact the rubber block 5 on the outer surface of the slide plate 4 during the swing of the rocker shaft 23, thereby improving the operational stability of the equipment. The hollow reed seat can reduce the weight of the reed seat, thereby improving its stability and performance during operation.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
