Description

Technical Field

[0001] This utility model relates to the field of tension adjustment technology for looms, specifically a tension adjustment device for looms. Background Technology

[0002] In the textile weaving industry, stable control of fabric tension is crucial for ensuring fabric quality and reducing weaving defects. Different types of fabrics (such as coarse-count denim and high-count cotton fabrics) have significantly different tension requirements. Excessive tension can easily lead to fabric breakage due to stretching, while insufficient tension can easily result in problems such as loose weaving and disordered weave.

[0003] Currently, the tension rollers of traditional loom tension adjustment devices are mostly of fixed specifications and cannot be flexibly changed according to the fabric material. Using hard rollers on coarse and stiff fabrics can easily cause slippage, while using high-friction rollers on fine and soft fabrics can easily cause wear. Although some devices can replace rollers, it is necessary to use tools such as wrenches to remove bolts, which is a cumbersome and time-consuming process that affects production efficiency. In view of this, we propose a loom tension adjustment device. Utility Model Content

[0004] The main objective of this invention is to provide a tension adjustment device for a loom, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a tension adjustment device for a loom, comprising a machine body, an input roller rotatably connected to the inner wall of the machine body, and an electric cylinder base fixedly connected to the outer wall of the machine body. An installation assembly is provided on the electric cylinder base, and the installation assembly includes:

[0006] A lifting seat is fixedly connected to the output end of the electric cylinder seat, and a sliding seat is slidably connected to the inner wall of the lifting seat;

[0007] A rotating shaft is rotatably connected to the inner wall of the sliding seat, and a rotating block is fixedly connected to the outer wall of the rotating shaft;

[0008] A limiting block is fixedly connected to the outer wall of the rotating block, and a synchronization disk is fixedly connected to the end of the rotating shaft away from the rotating block.

[0009] Preferably, a sliding rod is slidably connected to the inner wall of the synchronization disk, and an abutment disk is fixedly connected to the outer wall of the sliding rod.

[0010] Preferably, the sliding seat is provided in two sets, and the opposite sides of the two sets of sliding seats are elastically connected by compression springs, and the synchronizing disc and the abutting disc are elastically connected by a return spring.

[0011] Preferably, the inner wall of the machine body is rotatably connected to a mounting plate, and the outer wall of the mounting plate is rotatably connected to a tension roller.

[0012] Preferably, the mounting plate is provided with a docking groove, in which the rotating block can slide and avoid obstacles.

[0013] Preferably, the docking groove is provided with a T-shaped slot, and the limiting block can slide into the T-shaped slot.

[0014] Preferably, an output roller is rotatably connected to the inner wall of the machine body, and the output roller is located at the end of the machine body away from the input roller.

[0015] This invention provides a tension adjustment device for a weaving machine. It has the following beneficial effects:

[0016] (1) The tension adjustment device of this loom adjusts the spacing of the limit blocks by rotating the synchronous disc, and with the elastic engagement of the compression spring, tension rollers of different specifications can be quickly installed. The large-diameter rubber roller is suitable for coarse and hard fabrics, and avoids slippage by using high friction and elastic contact; the small-diameter ceramic roller is suitable for fine and soft fabrics, and reduces wear by using a low-friction surface. The electric cylinder base drives the lifting seat to adjust the height of the tension roller, further precisely controlling the fabric tension, realizing dual tension control of "roller type adaptation + height adjustment", ensuring that different fabric materials are subjected to uniform force during weaving, and improving the fabric quality.

[0017] (2) The tension adjustment device of the loom uses a limiting mechanism composed of a sliding bar and a reset spring to make the installation and replacement of the tension rollers complete without tools. The compression spring automatically drives the sliding seat to tighten, ensuring that the limiting block and the T-shaped slot are stably engaged, making replacement simple and convenient.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0028] Please see Figures 1-5 This utility model proposes a tension adjustment device for a weaving machine, including a machine body 1. An input roller 2 is rotatably connected to the inner wall of the machine body 1. An electric cylinder base 3 is fixedly connected to the outer wall of the machine body 1. An installation component 4 is provided on the electric cylinder base 3. The installation component 4 includes a lifting seat 41. The output end of the electric cylinder base 3 is fixedly connected to the lifting seat 41. The height of the lifting seat 41 can be changed by the electric cylinder base 3, thereby changing the position of the installation component 4, so that the position of the installation plate 5 and the tension roller 6 changes. A sliding seat 42 is slidably connected to the inner wall of the lifting seat 41. A rotating shaft 43 is rotatably connected to the inner wall of the sliding seat 42. A rotating block 44 is fixedly connected to the outer wall of the rotating shaft 43. A limit block 45 is fixedly connected to the outer wall of the rotating block 44. A synchronous disc 46 is fixedly connected to the end of the rotating shaft 43 away from the rotating block 44.

[0029] In this utility model, a sliding rod 47 is slidably connected to the inner wall of the synchronization disk 46, and an abutment disk 48 is fixedly connected to the outer wall of the sliding rod 47. Two sets of sliding seats 42 are provided, and the opposite sides of the two sets of sliding seats 42 are elastically connected by compression springs. The synchronization disk 46 and the abutment disk 48 are elastically connected by a return spring.

[0030] Furthermore, the inner wall of the machine body 1 is rotatably connected to a mounting plate 5, and the outer wall of the mounting plate 5 is rotatably connected to a tension roller 6. Both the mounting plate 5 and the tension roller 6 are provided with two specifications: mounting plate 5-small corresponds to tension roller 6-small, and mounting plate 5-large corresponds to tension roller 6-large. The diameters of mounting plate 5-small and mounting plate 5-large are different. As the names suggest, mounting plate 5-small is smaller. In addition to the different diameters of tension roller 6-small and tension roller 6-large, the materials are also different. The material of tension roller 6-small is ceramic, and the material of tension roller 6-large is rubber.

[0031] Furthermore, the mounting plate 5 is provided with a docking groove 7, and the rotating block 44 can slide in the docking groove 7 to avoid the rotating block 44. The docking groove 7 on the two types of mounting plates 5 has the same width but different lengths. The larger mounting plate 5 is longer and the smaller mounting plate 5 is shorter. The docking groove 7 is provided with a T-shaped slot 8. Two sets of T-shaped slots 8 are provided on one docking groove 7. The limiting block 45 can slide into the T-shaped slot 8. The inner wall of the machine body 1 is rotatably connected to an output roller 9, which is located at the end of the machine body 1 away from the input roller 2.

[0032] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0033] When using the tension roller 6-hour, due to the short docking groove 7, it is necessary to reduce the distance between the two limit blocks 45. By pulling the sliding rod 47, the abutment plate 48 is driven away from the surface of the lifting seat 41, and the sliding rod 47 is driven away from the inner wall of the lifting seat 41. At this time, the limiting state of the synchronous disc 46 is released. By rotating the synchronous disc 46, the rotating shaft 43 rotates on the inner wall of the lifting seat 41, driving the rotating block 44 to rotate synchronously, thereby changing the position of the limit blocks 45 and reducing the distance between the two limit blocks 45. Then, the installation work is carried out. First, push the two sets of sliding seats 42 away from each other, and then insert the rotating block 44 into the docking groove 7. Release the sliding seats 42, and through the reset of the compression spring, drive the two sets of sliding seats 42 to move closer to each other, thereby making the limit blocks 45 engage with the T-shaped slot 8, and completing the installation work of the tension roller 6-hour.

[0034] Additionally, when installing the tension roller 6-large, due to the length of the docking groove 7, the distance between the two limit blocks 45 needs to be increased. The operation is the same, allowing for quick replacement of the tension roller 6. This facilitates the use of different fabrics. For example, coarse-count denim yarn is thicker, harder, and stronger, so a large-diameter rubber tension roller 6 can be selected to increase the contact area and friction, preventing the yarn from slipping during high-speed operation and causing surface fuzzing or localized stretching and breakage. High-count denim yarn is thinner, softer, and more prone to breakage, so a small-diameter ceramic tension roller 6 (with a smooth surface and low coefficient of friction) can be used to reduce friction and wear between the yarn and the roller surface, reduce fuzzing, and improve the smoothness of the fabric surface.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
