Description

Technical Field

[0001] This utility model relates to the field of internal structure of circular looms, and in particular to a spring fixing device for a circular loom jump bar. Background Technology

[0002] When a circular loom is working, the warp tension must be uniform. If it is not uniform, the warp may wobble or become tangled. In traditional circular looms, the jump bar device includes a threading part and a hook part. The threading part is in a straight line with the bar body and is P-shaped. The flat yarn comes into contact with the arc segment of the P-shape, which often causes the flat yarn to twist. This not only affects the normal operation of the circular loom but also affects the weaving quality of the bag.

[0003] During use, the tension spring and the jump bar are prone to detachment, causing the jump bar to lose its elasticity. This affects the entire circular loom's operation, the uniform delivery of warp threads within the loom, and the overall quality of the bag weaving. Utility Model Content

[0004] One objective of this invention is to provide a circular loom spring fixing device that at least solves any of the above-mentioned technical problems.

[0005] A further objective of this invention is to prevent the spring from falling off and affecting the overall elasticity.

[0006] Another further objective of this invention is to improve the elasticity and service life of circular looms.

[0007] In particular, this utility model provides a fixing device for a spring on a circular loom, comprising a fixing plate, wherein the fixing plate is symmetrically arranged on the left and right sides; A first fixed shaft, a second fixed shaft, a third fixed shaft, and a fourth fixed shaft are provided, all of which are disposed between the two fixed plates. A jumping pole, the middle part of which is fastened to the fourth fixed shaft; A rotating ring is sleeved on both ends of the first fixed shaft, and both ends of the second fixed shaft are fixedly connected to the ring wall of the rotating ring.

[0008] Furthermore, the jump pole includes a first jump pole support and a second jump pole support, with a positioning buckle connecting the first jump pole support and the second jump pole support. The first jump pole support is located above the positioning buckle, and the second jump pole support is located below the positioning buckle.

[0009] Furthermore, both the first and second jump pole supports are provided with hooks at their ends, and a spring is provided between the lower part of the second jump pole support and the second fixed shaft.

[0010] Furthermore, both ends of the spring are closed loops.

[0011] Furthermore, the third fixed axis is located below the fourth fixed axis and is positioned close to the third fixed axis.

[0012] The technical effects and advantages of this utility model are as follows: This invention features rotating rings at both ends of a first fixed shaft and a second fixed shaft between the rotating rings. The second fixed shaft rotates around the first fixed shaft via the rotating rings and is connected to a spring. When the jump bar jumps, the spring is stressed and can swing along the first fixed shaft, thereby reducing the stress on the fixed end of the spring, preventing the spring end from falling off, which would affect the overall use of the equipment and the frequent occurrence of flat yarn twisting. It also avoids affecting the normal operation of the circular loom and the weaving quality of the bag. Attached Figure Description

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.

[0018] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2This is a front view structural diagram of the present utility model. Figure 3 This utility model Figure 2 Schematic diagram of the cross-sectional structure along the AA direction.

[0019] This embodiment provides a circular loom jump bar spring fixing device, including a fixing plate 1, a first fixing shaft 2, a second fixing shaft 301, a jump bar 701, a swivel ring 3, a third fixing shaft 5, and a fourth fixing shaft 6. The fixing plates 1 are symmetrically arranged on the left and right sides. The first fixing shaft 2, the second fixing shaft 301, the third fixing shaft 5, and the fourth fixing shaft 6 are all arranged between the two fixing plates 1. The middle part of the jump bar 701 is fastened to the fourth fixing shaft 6. The swivel ring 3 is sleeved on both ends of the first fixing shaft 2, and both ends of the second fixing shaft 301 are fixedly connected to the ring wall of the swivel ring 3.

[0020] It should be further explained that the jump pole 701 includes a first jump pole support 8 and a second jump pole support 9. A positioning buckle is connected between the first jump pole support 8 and the second jump pole support 9. The first jump pole support 8 is located above the positioning buckle, and the second jump pole support 9 is located below the positioning buckle.

[0021] It should be further noted that both the first jump pole support 8 and the second jump pole support 9 are provided with hooks 901 at their ends, and a spring 4 is provided between the lower part of the second jump pole support 9 and the second fixed shaft 301.

[0022] It should be further noted that both ends of the spring 4 are closed loops.

[0023] It should be further noted that the third fixed shaft 5 is located below the fourth fixed shaft 6 and is positioned close to the third fixed shaft 5.

[0024] Specifically, the support frame consists of a pair of symmetrically arranged fixed plates 1; between the two fixed plates 1, a first fixed shaft 2, a second fixed shaft 301, a third fixed shaft 5, and a fourth fixed shaft 6 are parallel and fixedly arranged. These fixed shafts together constitute the basic coordinate system for the movement of the entire mechanism. In particular, the third fixed shaft 5 is located below and adjacent to the fourth fixed shaft 6, and is used to provide auxiliary positioning or limitation when the jump bar 701 moves.

[0025] The jump bar 701 assembly is the core moving part that performs the knitting function. Its main body is a jump bar 701, the middle of which is fastened to the fourth fixed shaft 6 through a shaft hole or groove structure, so that the jump bar 701 can jump up and down with the fourth fixed shaft 6 as the fulcrum.

[0026] Furthermore, the jump bar 701 adopts a split-type optimized design, comprising an upper first jump bar support 8 and a lower second jump bar support 9. The first jump bar support 8 and the second jump bar support 9 are rigidly connected and transitioned through an integral or connected positioning buckle. At the ends of both the first jump bar support 8 and the second jump bar support 9, hooks 901 at a specific angle are machined, which are used to reliably guide and support the braiding threads.

[0027] The swing support is the key component for realizing the innovative function of this utility model. It mainly consists of two rotating rings 3. These two rotating rings 3 are rotatably fitted onto the left and right ends of the first fixed shaft 2, respectively, meaning that the rotating rings 3 can rotate freely with the first fixed shaft 2 as the axis. The second fixed shaft 301 is fixedly inserted into the ring walls of these two rotating rings 3, thereby forming a linkage unit that can swing as a whole relative to the first fixed shaft 2, consisting of the second fixed shaft 301, the rotating rings 3, and the first fixed shaft 2.

[0028] The elastic reset unit is used to provide the necessary restoring force for the jump bar 701 to ensure its jumping rhythm. In this embodiment, the unit is a tension spring 4. The upper end of the spring 4 is connected to the lower part of the second jump bar support 9 of the jump bar 701 through a closed loop at its end; its lower end is also connected to the swingable second fixed shaft 301 through a closed loop.

[0029] The working principle and beneficial effects of this utility model are detailed below: During the operation of the circular loom, the jump bar 701, driven by an external force or under the tension of the yarn, bounces up and down at a high frequency around the fourth fixed shaft 6. When the jump bar 701 moves downward, it stretches the spring 4. Unlike the traditional rigid connection method, in this invention, the lower end of the spring 4 is not fixed to a static fulcrum, but is connected to a "swinging support" composed of a rotating ring 3 and a second fixed shaft 301.

[0030] When spring 4 is stretched, the force it generates acts on the second fixed shaft 301. Since the second fixed shaft 301 is mounted on the first fixed shaft 2 via the rotating ring 3, this force naturally transforms into a torque, driving the entire "swing support" (i.e., the second fixed shaft 301 and the rotating ring 3) to undergo a slight, compliant swing around the first fixed shaft 2. This swing process perfectly adapts to the subtle changes in the angle and direction of spring 4 in the trajectory of the jumping bar 701.

[0031] By transforming the connection point of spring 4 from a "dead point" subjected to complex stresses into a "live point" capable of adaptive adjustment, the static bending stress and dynamic fatigue damage at both ends of spring 4, especially at the connection with the second fixed shaft 301, are greatly reduced. This fundamentally eliminates the risk of deformation, loosening, or even breakage of the end rings of spring 4 due to stress concentration, ensuring the reliability of the mechanism's long-term continuous operation. Through compliant oscillation, unwanted radial torsion (i.e., "flat wire torsion") of spring 4 during operation is avoided, ensuring that the tension acting on the jump bar 701 is stable and uniform. Ultimately, by ensuring the precise coordination between the movement of the jump bar 701 and the force of spring 4, this mechanism provides a more stable weaving environment for the circular loom, significantly improving the flatness and overall quality of the woven bags.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
