Description

Technical Field

[0001] This utility model belongs to the field of textile equipment, and in particular relates to a high-capacity warping machine. Background Technology

[0002] A warping machine is a piece of equipment in the textile industry used to prepare warp yarns for weaving or knitting. It primarily draws multiple yarns from bobbins on a creel, guides them through a series of guiding and tension control devices, and winds them onto a large warp beam for subsequent weaving processes. Warping machines are crucial for ensuring efficient and precise warp preparation, guaranteeing uniform warp tension and neat alignment, improving production efficiency and product quality, and ultimately producing high-quality woven fabrics.

[0003] Generally, a warping machine includes a yarn supply system, a tension control and adjustment system, a yarn guiding and arranging system, and a detection and inspection system. Large-capacity warping machines typically employ larger beam diameters and wider beam lengths to provide more warp winding nodes. Due to the larger size and mass of the warp beam in large-capacity warping machines, higher demands are placed on the load capacity of their transmission system and the accuracy of their tension control system. The tightness of the warp winding affects the amount of warp yarn per unit volume; the more uniform and tight the winding, the greater the capacity. However, excessive tightness can lead to yarn stretching, deformation, or breakage. Therefore, in addition to installing tension control devices in the direction of yarn exit, tension control devices should also be installed near the warp beam to ensure yarn quality. Utility Model Content

[0004] This invention addresses the technical problems existing in the aforementioned warping machines by proposing a high-capacity warping machine that is rationally designed, centrally arranged along the warp beam direction, used to control the winding tension performance of the warp beam, and conducive to ensuring yarn quality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a high-capacity warping machine, including a warp beam and rollers. The warp beam has a support frame and a transmission control housing at both ends. The rollers are mounted on the warp beam and have two rows of staggered wiring holes. A tensioning device is provided in the upper direction of the rollers. The tensioning device includes two fixed hinge supports, and two tensioning rollers are arranged in a staggered manner between the fixed hinge supports. Spring support mechanisms are provided at both ends of the tensioning rollers. The two rows of wiring holes correspond one-to-one with the two tensioning rollers and are used to transmit two rows of yarn. A self-balancing component is provided on the roller surface of the tensioning rollers. The self-balancing component includes two fixed plates symmetrically arranged on the tensioning rollers. Multiple elastic plates distributed along the length direction are provided on the outer side of the fixed plates, and the outer side of the elastic plates is curved.

[0006] Preferably, the fixing plate includes a connecting section, and the connecting section has an arc plate section at the end away from the tension roller. Both ends of the arc plate section are provided with clamping openings, and the clamping openings are slidably engaged with both ends of the elastic plate.

[0007] Preferably, the fixing plate is provided with a plurality of countersunk holes, which are used to install screws that connect the fixing plate and the tension roller.

[0008] Preferably, the elastic plate includes a curved section, with arc transition sections at both ends of the curved section, and a sliding compression section extending towards the clamping opening at the end of the arc transition section.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Examples, such as Figures 1-5As shown, this utility model provides a high-capacity warping machine, including a warp beam 3 and a roller 4. A support frame 1 and a transmission control housing 2 are provided at both ends of the warp beam 3. The roller 4 is mounted on the warp beam 3 and has two rows of staggered wiring holes 5. The support frame 1 and transmission control housing 2 support the high-capacity warp beam 3 and roller 4, and input continuous rotational power to the warp beam 3. The wiring holes 5 on the roller 4 are used to connect yarn bundles. Based on this, the present invention provides a tensioning device 6 on the winding feed side of the roller 4 in the upper direction. The tensioning device 6 includes two fixed hinge supports 61, and two tensioning rollers 62 are arranged alternately between the fixed hinge supports 61. Spring support mechanisms 63 are provided at both ends of the tensioning rollers 62. Two rows of wiring holes 5 are matched with the two tensioning rollers 62 in a one-to-one correspondence and are used to convey two rows of yarn. A self-balancing component 64 is provided on the roller surface of the tensioning rollers 62. The self-balancing component 64 includes two fixed plates 641 symmetrically arranged on the tensioning rollers 62. Multiple elastic plates 642 distributed along the length direction are provided on the outer side of the fixed plates 641. The outer side of the elastic plates 642 is curved.

[0023] Specifically, the fixed hinge support 61 is used to establish a fixed connection with the warping machine, providing a stable and reliable support foundation for the tension roller 62, thus ensuring that the tensioning device 6 is uniformly arranged in the direction of the warp beam 3 of the warping machine. Under the pressure of the spring support mechanism 63 and the yarn, the tension roller 62 can generate corresponding displacement to ensure the tension of the yarn. Since different wiring holes 5 on the roller 4 correspond to different yarn groups, and the high-capacity warp beam 3 has two rows of wiring holes 5, this invention provides two tension rollers 62 to provide sufficient yarn travel area at the bottom of the tension roller 62, avoiding knotting of yarns in different rows. Furthermore, in order to improve the tensioning effect of each yarn group, this invention, in addition to using the elastic tensioning effect provided by the tension roller 62, also uses multiple elastic plates 642 of the self-balancing component 64 to flexibly correspond to different yarn groups. Under the pressure of the yarn group, the elastic plates 642 can generate corresponding elastic deformation, thereby further improving the quality of yarn winding onto the roller 4 at different positions.

[0024] To improve the adaptive performance of the elastic plate 642, the fixed plate 641 provided by this utility model includes a connecting section 6411. At the end of the connecting section 6411 away from the tension roller 62, an arc plate section 6412 is provided. Both ends of the arc plate section 6412 are provided with clamping openings 6413, which slide in conjunction with the ends of the elastic plate 642. The surface of the elastic plate 642 is in direct contact with the yarn. The yarn can apply a certain pressure to the elastic plate 642 along its movement path. The elastic plate 642, under pressure, can slide and deform along the opening wall of the clamping opening 6413, thereby balancing the real-time pressure of the yarn. Simultaneously, the elastic plate 642 and the tension roller 62 can rotate as a whole. Along the path of rotation, the pressure of the yarn can also be balanced, thus ensuring the adaptive performance of the pair of elastic plates 642 in contact with the yarn group and facilitating better tension quality.

[0025] To facilitate the installation of the fixing plate 641, the fixing plate 641 provided in this utility model is provided with multiple countersunk holes 6414, which are used to install screws connecting the fixing plate 641 and the tension roller 62. The two fixing plates 641 serve as the mounting base for the two rows of elastic plates 642, providing movable support for the elastic plates 642. The two fixing plates 641 are clamped onto the tension roller 62 and secured with screws, resulting in strong assemblability and high reliability.

[0026] To improve the practicality of the elastic plate 642, the elastic plate 642 provided by this utility model includes a curved surface segment 6421, with arc transition segments 6422 at both ends of the curved surface segment 6421, and a sliding compression segment 6423 that bends and extends toward the clamping opening 6413 at the end of the arc transition segment 6422. Among them, the curved section 6421 and the arc transition section 6422 can maintain good contact with the moving yarn. In particular, the arc transition section 6422 will not cut the yarn, which is conducive to ensuring the surface quality of the yarn. The elastic plate 642 can complete the corresponding rotation under the pressure of the yarn, and the sliding compression section 6423 and the clamping port 6413 have a reasonable sliding margin. When the elastic plate 642 is under pressure, the sliding compression section 6423 can generate a corresponding deflection along the clamping port 6413, so that the curved section 6421 and the arc transition section 6422 of the elastic plate 642 under real-time force form a cam-like structure with another elastic plate 642, thereby changing the actual distance from the yarn to the center of the tension roller 62, so a certain elastic tensioning effect can be achieved.

[0027] To improve the elastic support effect of the spring support mechanism 63 on the tension roller 62, the spring support mechanism 63 provided by this utility model includes a support block 631. The support block 631 has two pairs of support holes, in which springs 632 are installed. Each pair of springs 632 has a movable seat 633 at its top, which is located at the shaft end of the tension roller 62. The fixed hinge support 61 has a guide hole 611 for the movement of the tension roller. The support block 631 provides a basic position point for the springs 632. The tops of the springs 632 support the tension roller 62 and the movable seat 633. The real-time pressure of the tension roller 62 can achieve dynamic balance with the springs 632. Furthermore, the displacement direction of the tension roller 62 is inclined, which can change the distance between the yarn and the winding node during the balancing action, thereby adjusting the real-time tensioning effect. It should be noted that the tension roller 62 can be made of a lighter material to ensure the support performance of the springs 632 and the sensitivity in achieving the dynamic balance position.

[0028] Furthermore, the support block 631 provided by this utility model is disposed inside the support box 634, and the side of the support box 634 is provided with a passage for nesting and fixing the hinge support 61. The spring support mechanism 63 can be installed in a relatively sealed manner by the support box 634, which provides a certain degree of protection and prevents workers from walking back and forth and bumping into the spring support mechanism 63, thus affecting the tension of the yarn.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
