AI Technical Summary
[0003]目前，市场上现有的经纱张力均衡装置，其张力调节功能通常依赖于机械式的调节机构（如调节弹簧、配重块或螺杆），不同经纱需要不同张力，当需要调节经纱张力时，必须首先停止织机的运行，然后由人工对特定的调节点进行手动调整；织机频繁启停会中断连续的生产过程，每次停机及重新启动都会占用宝贵的生产时间，导致设备运转率下降，单位时间内的产量降低，因此，需要设计一种用于涤纶坯布织机的经纱张力均衡装置解决上述问题
1.通过气缸作为核心驱动件，动力输出平稳，当需要进行经纱之间的张力拉紧时，只需要气缸驱动经纱辊相互远离，松的经纱就会被张力拉紧，实现不停机调节，避免生产中断，显著提高设备的运转率和织造效率。

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of balancing device technology, specifically relating to a warp tension balancing device for polyester fabric looms. Background Technology
[0002] In the weaving process, the uniformity and stability of warp tension are key factors in ensuring fabric quality and production efficiency. The warp tension equalization device is a core component of modern looms. Its function is to adjust the tension of multiple warp yarns, preventing fabric defects such as warp breaks, skipped stitches, and uneven weaving caused by uneven tension, thereby ensuring fabric quality.
[0003] Currently, existing warp tension balancing devices on the market typically rely on mechanical adjustment mechanisms (such as adjusting springs, counterweights, or screws) for tension adjustment. Different warp yarns require different tensions, and when warp tension needs to be adjusted, the loom must first be stopped, and then manual adjustment must be performed on specific adjustment points. Frequent start-ups and shutdowns of the loom interrupt the continuous production process, and each stop and restart consumes valuable production time, leading to a decrease in equipment operating rate and a reduction in output per unit time. Therefore, it is necessary to design a warp tension balancing device for polyester fabric looms to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a warp tension balancing device for polyester fabric looms to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a warp tension balancing device for a polyester fabric loom, comprising a base plate, a groove formed on the upper surface of the base plate, a movable support plate slidably mounted on the surface of the base plate, a slider fixed to the lower part of the movable support plate, a warp roller B rotatably mounted between the two movable support plates, a fixed plate fixed to the surface of the base plate, a cylinder B mounted on the fixed plate, a telescopic rod B fixed to the cylinder B via a coupling, a fixed support plate mounted on the upper surface of the base plate, and a warp roller A slidably mounted between the two fixed support plates.
[0006] Preferably, the fixed support plate is provided with an adjustment groove, the warp roller A is located inside the adjustment groove, an adjustment frame is installed on the upper part of the fixed support plate, a support frame is fixed on the upper surface of the fixed support plate, a cylinder A is installed on the support frame, and a telescopic rod A is fixed to the lower part of the cylinder A through a coupling.
[0007] Preferably, the end of the telescopic rod B is fixed to the surface of the connecting plate, and the slider is installed inside the slide groove.
[0008] Preferably, the adjusting frame is configured as an inverted concave shape, and the fixed support plate and the seat plate are integrally formed.
[0009] Preferably, the lower end of the telescopic rod A is fixed to the upper surface of the adjusting frame, and the adjusting frame is locked onto the upper part of the fixed support plate.
[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. With cylinders as the core driving component, the power output is stable. When it is necessary to tighten the tension between the warp yarns, the cylinders only need to drive the warp rollers to move away from each other, and the loose warp yarns will be tightened. This allows for non-stop adjustment, avoids production interruption, and significantly improves the equipment's operating rate and weaving efficiency.
[0011] 2. By adjusting the height of the warp roller using a cylinder as the core driving component, the encirclement angle and direction of the warp yarns on the roller can be changed, thereby adapting to the specific process requirements of different raw materials (such as filaments and staple fibers), different warp densities, and different fabric structures on the clarity of warp opening and friction state.

[0013] 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.
[0014] Example 1: Please refer to Figures 1 to 3This utility model provides a technical solution for a warp tension balancing device for a polyester fabric loom: A warp tension balancing device for a polyester fabric loom includes a base plate 1, a groove 11 on the upper surface of the base plate 1, a movable support plate 2 slidably mounted on the surface of the base plate 1, a slider 16 fixed at the lower part of the movable support plate 2, a warp roller B15 rotatably mounted between the two movable support plates 2, a fixed plate 10 fixed on the surface of the base plate 1, a cylinder B12 mounted on the fixed plate 10, a telescopic rod B13 fixed to the cylinder B12 through a coupling, a fixed support plate 8 mounted on the upper surface of the base plate 1, and a warp roller A9 slidably mounted between the two fixed support plates 8.
[0015] As can be seen from the above description, the present invention has the following beneficial effects: the cylinder B12 drives the telescopic rod B13 to pull the connecting plate 14 to move, and the connecting plate 14 is fixed together with the movable support plate 2. The slider 16 is limited by the slide groove 11, thereby realizing the horizontal movement of the warp roller B15 inside the movable support plate 2, so as to achieve the purpose of adjusting the warp tension.
[0016] Example 2: Please refer to Figures 1 to 3 As shown, based on Embodiment 1, this utility model provides a technical solution for a warp tension balancing device for a polyester fabric loom: An adjustment groove 3 is provided on the fixed support plate 8, the warp roller A9 is located inside the adjustment groove 3, an adjustment frame 7 is installed on the upper part of the fixed support plate 8, a support frame 4 is fixed on the upper surface of the fixed support plate 8, a cylinder A5 is installed on the support frame 4, and a telescopic rod A6 is fixed to the lower part of the cylinder A5 via a coupling. The telescopic rod A6 is used to pull the adjustment frame 7 up and down; the end of the telescopic rod B13 is fixed to the surface of the connecting plate 14, and a slider 16 is installed inside the slide groove 11. The slider 16 is used to restrict the stable horizontal movement of the moving support plate 2; the adjustment frame 7 is designed as an inverted concave shape, and the fixed support plate 8 and the seat plate 1 are integrally formed; the lower end of the telescopic rod A6 is fixed to the upper surface of the adjustment frame 7, and the adjustment frame 7 is locked in the upper part of the fixed support plate 8 to ensure that the warp roller A9 can move up and down stably.
[0017] The working principle and usage of this utility model are as follows: One end of the warp yarn is wound around the warp roller B15, and then around the warp roller A9 for winding. The tension of the warp yarn between the warp rollers B15 and A9 is achieved by moving them further apart; when they move apart, the warp yarn is tensioned, and when they move closer, the warp yarn is relaxed. The cylinder B12 drives the telescopic rod B13 to move the connecting plate 14. The connecting plate 14 is integrally fixed with the movable support plate 2, and the slider 16 is limited by the slide groove 11. This allows the warp roller B15 inside the movable support plate 2 to move horizontally, thus adjusting the warp yarn tension. The cylinder A5 drives the telescopic rod A6 to move the adjusting frame 7 vertically. The adjusting frame 7 is connected to the warp roller A9 and can adjust the vertical movement of the warp roller A9, thereby adjusting the horizontal misalignment between the warp roller A9 and the warp roller B15, thus adjusting the warp path.
