Description

Technical Field

[0001] This utility model relates to the field of rapier looms, specifically a shock-absorbing base for operating low-vibration, low-noise rapier looms. Background Technology

[0002] As one of the core pieces of equipment in the modern textile industry, the rapier loom is widely used in the production of various fabrics such as cotton, wool, silk, and linen due to its advantages such as flexible weft insertion and wide applicability to various yarns. In the continuous production of textile workshops, the rapier loom drives the reed seat, heald frame, and other components to reciprocate through the high-speed rotation of the main shaft, thereby realizing the interlacing of warp and weft yarns. Its operating efficiency directly determines the output and quality of the fabric. However, during high-speed operation, the inertial impact and periodic vibration of various moving parts (such as the crank-connecting rod mechanism and the beat-up mechanism) of rapier looms are extremely significant. These vibrations not only transmit to the ground through the machine body, causing resonance in the workshop floor, but also generate a lot of noise due to friction and collision between parts. Long-term exposure to a high-noise environment can lead to hearing damage and distraction for operators, increasing the risk of production accidents. Continuous vibration can also cause the loom parts to loosen and wear more quickly, affecting the weaving precision of the fabric and reducing the product qualification rate. The shock-absorbing bases of existing rapier looms mostly use a single rubber pad or spring structure, which has poor shock absorption and buffering effect. The rubber pad is greatly affected by temperature, and its elasticity decays significantly after long-term use. Although the spring can withstand a large load, its resonant frequency is fixed, making it difficult to adapt to the vibration frequency of the loom under different working conditions, and it is easy to produce resonance amplification phenomenon. Traditional bases are often rigidly connected to the loom body with bolts, resulting in a short vibration transmission path and an inability to effectively block vibration energy. Furthermore, the base lacks anti-slip and limiting structures at the bottom, making it prone to displacement under high-frequency vibrations of the loom. This causes the loom to shift relative to surrounding equipment, affecting collaborative operations. Furthermore, noise reduction is achieved only indirectly through vibration damping without designing a dedicated noise reduction structure for the vibration source and noise propagation path. This results in noise primarily spreading through air and solid-borne sound transmission (such as the ground and walls), leading to limited noise reduction effectiveness. Therefore, it is necessary to design a vibration damping base for operating low-vibration and low-noise rapier looms to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a shock-absorbing base for operating a low-vibration, low-noise rapier loom, in order to solve the problems mentioned in the background art.

[0015] 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.

[0016] Example 1: Please refer to Figure 1-4 As shown, this utility model provides a shock-absorbing base for operating a low-vibration, low-noise rapier loom, including a base 1 adapted to the rapier loom equipment. Connecting blocks 3 are hinged to both sides of the base 1 via fixed shafts 2. A buffer for shock absorption support is hinged to the other side of the connecting blocks 3. A support for noise reduction is installed at the bottom of the buffer.

[0017] It should be added that the top of the base 1 can be installed and fixed to the rapier loom by multiple bolts. The buffers on both sides of the base 1 and located at the corners support the base 1 through the support members. The support members at the four corners can expand the support area of ​​the base 1. When the equipment shakes violently during operation, it can absorb shock and buffer, prevent the equipment from vibrating violently and generating noise. The support members can conduct and reduce noise, preventing noise from being emitted and polluting the production environment.

[0018] Specifically, the buffer includes two support rods 4 that are hinged to both sides of the connecting block 3, and support legs 5 that are hinged to the other end of the two support rods 4. Support parts 6 are integrally formed at the bottom of the support legs 5 and at the two corners. The buffer also includes support seats 7 that are welded to both sides of the support rods 4, and shock absorber rods 8 are hinged between the two support seats 7. A first spring 9 for resisting pressure is fitted on the outside of the shock absorber rod 8.

[0019] The four support rods 4 are divided into two groups, with the two groups of support rods 4 located on both sides of the connecting block 3. The two support rods 4 are set up vertically, and the two ends of the support rods 4 are hinged to the support legs 5 and the connecting block 3, respectively. The shock absorber rod 8 between the two support seats 7 is set at an angle. The first spring 9 on the outside of the shock absorber rod 8 can support the two connecting rods, increase the compressive strength of the shock absorber rod 8, and at the same time, the shock absorber rod 8 can absorb and buffer the dynamic potential energy, reduce the vibration amplitude, and improve the shock absorption and buffering protection effect of the base 1 in supporting the equipment.

[0020] More specifically, a sliding rod 10 is hinged between two support rods 4, and a rotating block 11 is hinged between the other two support rods 4. A second spring 12 is fixedly connected between the rotating block 11 and the sliding rod 10. The sliding rod 10 passes through the rotating block 11 and is slidably connected to it. A guide rod 15 passes through the inner side of the sliding rod 10 and is located inside the second spring 12. The guide rod 15 passes through the rotating block 11 and is slidably connected to it.

[0021] It should be added that when the distance between the two sets of support rods 4 changes, the sliding rod 10 slides through the rotating block 11, the rotating block 11 rotates due to the influence of the sliding rod 10, the guide rod 15 slides through the rotating block 11, and the second spring 12 can resist the pressure between the sliding rod 10 and the rotating block 11, increase the compressive strength of the two sets of support rods 4, and improve the shock absorption and buffering protection effect of the support rods 4.

[0022] Furthermore, the support includes a foot 13 hinged to the support part 6, a bolt rod 14 is threaded through and screwed onto the inner side of the support part 6, the bolt rod 14 passes through the foot 13 and is rotatably connected to it, and an anti-slip pad 16 is laid on the bottom of the foot 13.

[0023] Among them, the pad 13 can be hinged to rotate around the bolt rod 14 and the support part 6. The anti-slip pad 16 at the bottom of the pad 13 is made of rubber. The anti-slip pad 16 is in contact with the ground to prevent the pad 13 from sliding, and at the same time, it can reduce noise pollution to the environment.

[0024] Working principle: When the equipment on the top of the base 1 vibrates during operation, the first spring 9 on the outside of the shock absorber rod 8 supports the two connecting rods, increasing the compressive strength of the shock absorber rod 8. At the same time, the shock absorber rod 8 absorbs and buffers the dynamic potential energy. Then, the sliding rod 10 slides through the rotating block 11, and the rotating block 11 rotates due to the influence of the sliding rod 10. The guide rod 15 slides through the rotating block 11. At the same time, the second spring 12 on the outside of the guide rod 15 resists the pressure between the sliding rod 10 and the rotating block 11. In addition, the anti-slip pad 16 at the bottom of the pad 13 is in contact with the ground to prevent the pad 13 from sliding.
