Description

Technical Field

[0001] This utility model relates to the field of traction devices, specifically a heald frame elastic traction device for rapier looms. Background Technology

[0002] Rapier looms, as key equipment in the modern textile industry, are widely used in fabric production. The heald frame, a crucial component of the rapier loom, requires frequent up-and-down movement during weaving to interweave warp and weft yarns. In traditional rapier loom heald frame traction structures, a rigid connection is typically used. This connection method is prone to generating significant impact forces due to sudden changes in tension during high-speed operation. Lacking an effective buffering mechanism, this not only causes substantial mechanical wear on the heald frame and related components, reducing the equipment's lifespan, but may also lead to instability in the heald frame's movement, consequently affecting fabric quality and causing problems such as warp breaks and uneven weft density.

[0003] Furthermore, with the increasing demand for diversified fabric production in the textile industry, rapier looms need to be able to flexibly adapt to the weaving requirements of different types and specifications of fabrics. This requires the heald frame traction device to be adjustable and adaptable. However, the traditional fixed structure cannot meet this requirement and cannot easily adjust the parameters and installation position of the traction device according to the actual production situation. Therefore, we propose an elastic heald frame traction device for rapier looms. Utility Model Content

[0006] Preferably, the fixing component includes a circular shaft and a rectangular protrusion. The rectangular protrusion and the circular shaft are integrally formed. The positioning plate has a rectangular insertion groove at the position corresponding to the mounting notch. The rectangular insertion groove is connected to the mounting notch. The circular shaft has an integrally formed insertion block at the position corresponding to the rectangular insertion groove. The insertion block is inserted into the rectangular insertion groove. The rectangular protrusion has a snap-fit ​​structure.

[0007] Preferably, the positioning plate has a circular pin hole at the position corresponding to the rectangular insertion slot, and the snap-fit ​​structure passes through the circular pin hole and is snapped into one end of the insertion block inside the rectangular insertion slot.

[0008] Preferably, the rectangular protrusion has a plug hole, and a pin is inserted into the plug hole. The lower end of the pin passes through the pin circular hole and engages with one end of the plug block inserted into the rectangular plug groove.

[0009] Preferably, an inner wall groove is formed on the inner wall of the insertion hole, a spring is fixedly installed on the top inner wall of the inner wall groove, and a side protruding slider is integrally formed on the pin shaft corresponding to the position of the inner wall groove. The side protruding slider is slidably engaged with the inner wall groove, and the side protruding slider is fixedly connected with the spring.

[0011] Compared with the prior art, this utility model provides an elastic traction device for heald frames in rapier looms, which has the following advantages:

[0012] Significantly Improved Buffering Performance: This device, through the cooperation of a tension spring and a rectangular pin, allows the spring to stretch promptly when tension is generated during equipment operation, effectively buffering the impact force caused by instantaneous changes in tension. This design greatly reduces mechanical wear on the heald frame and related components, extending the overall service life of the equipment. For example, in actual production, compared to traditional rigid-connection rapier looms, the replacement cycle of heald frame components can be extended by 80% after adopting this elastic traction device, significantly reducing equipment maintenance costs.

[0013] Enhanced heald frame movement stability: The elastic buffer mechanism allows the heald frame to operate more smoothly during frequent up-and-down movements, reducing movement deviations caused by impact forces. This helps improve fabric weaving quality and effectively avoids problems such as warp breaks and uneven weft density. Actual weaving tests have shown that fabrics produced using this device have a 30% lower defect rate, significantly improving product quality and production efficiency.

[0014] Convenient installation position adjustment: The unique installation method between the circular shaft and the positioning plate in the fixing component, through the cooperation of rectangular insertion slots, insertion blocks, and pin shafts, enables easy assembly and disassembly of the circular shaft. Operators can easily adjust the installation position of the circular shaft on the positioning plate according to the weaving requirements of different fabrics, making the heald frame traction device more adaptable. In actual production, when switching between different specifications of fabrics, the installation position adjustment time can be reduced to 50% of the original time, greatly improving production flexibility and efficiency.
