Description

Technical Field

[0001] This utility model relates to the field of spinning circular looms, specifically a yarn feeding device for spinning circular looms. Background Technology

[0002] A circular spinning loom is a textile weaving machine that arranges multiple yarns in a circle and then uses a mechanical structure to complete the warp opening, weft insertion, and weft interlacing to directly and continuously weave a seamless cylindrical fabric. It is mainly used for weaving yarns into shapes, rather than for fiber spinning processes, and is a specialized machine for producing products such as tubular fabrics and woven bag fabrics.

[0003] In existing technology, when a circular spinning loom is in use, the yarn to be processed is usually placed in the yarn feeding structure located at the top of the circular spinning loom. The yarn feeding roller is rotated by a motor to achieve the yarn feeding effect. The pressure roller in the yarn feeding structure holds the yarn so that it can be processed smoothly and stably by the circular spinning loom. However, when the yarn is fed by the yarn feeding roller, there is no separation function between the yarn feeding roller and the pressure roller. The yarn is only limited by a simple yarn guiding component, which cannot evenly adjust and stably separate the spacing between the yarns. This makes it easy for the yarns to have uneven spacing and become entangled. As a result, the yarn trajectory is easily deviated when being fed, which not only affects the yarn feeding stability, but also easily causes yarn breakage and uneven fabric texture. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, when feeding yarn through a yarn feeding roller, there is a lack of separation between the yarn feeding roller and the pressure roller. The yarn is only limited by a simple yarn guiding component, which cannot uniformly adjust and stably separate the spacing between the yarns. This leads to uneven spacing and tangling of the yarns, which in turn causes the yarn trajectory to deviate during feeding. This affects the stability of yarn feeding and can easily cause yarn breakage and uneven fabric texture. This utility model proposes a yarn feeding device for a spinning circular loom.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a yarn feeding device for a spinning circular loom, including a yarn feeding base, a yarn feeding roller and a pressure roller are provided on one side of the yarn feeding base, a connecting frame is fixedly connected to the top of the yarn feeding base, and an adjustment mechanism is provided on one side of the connecting frame.

[0006] The adjusting mechanism includes a threaded rod, the surface of which is rotatably connected to the inner cavity of the connecting frame. A fixing block is fixedly connected to one side of the connecting frame. A threaded ring block is threadedly connected to the surface of the threaded rod. A movable block is fixedly connected to the surface of the threaded ring block. A rhomboid telescopic frame is fixedly connected to the bottom of the fixing block and the movable block. Multiple adjusting blocks are fixedly connected to the top of the rhomboid telescopic frame. The inner cavities of the multiple adjusting blocks are all fitted onto the surface of the threaded rod. A guide component is provided on the top of the movable block, the fixing block, and the multiple adjusting blocks. A limit component is provided on one side of the connecting frame.

[0007] Preferably, the limiting component includes a fixed rod, both ends of which are fixedly connected to the inner cavity of the connecting frame, the inner cavities of the moving block and the plurality of adjusting blocks are slidably connected to the surface of the fixed rod, and a limiting plate is fixedly connected to one side of the connecting frame.

[0008] Preferably, the guiding assembly includes a guiding ring block, one side of which is fixedly connected to the top of a fixed block, and a rotating ball is movably connected to the inner cavity of the guiding ring block.

[0009] Preferably, the surface of the guide ring block is provided with an installation groove, the inner cavity of the installation groove is fixedly connected to a fixing plate, one side of the fixing plate is fixedly connected to a spring, one end of the spring is fixedly connected to a baffle, and one side of the baffle is rotatably connected to the inner cavity of the guide ring block.

[0010] Preferably, both sides of the connecting frame are rotatably connected to a limiting ring block, and the inner cavity of both limiting ring blocks is fixedly connected to the surface of the threaded rod.

[0011] Preferably, a guide plate is fixedly connected to one side of the yarn feeding base, and the guide plate is disposed between the connecting frame and the pressure roller.

[0012] Preferably, a first limiting block is fixedly connected to the surface of the yarn feeding roller shaft, and a second limiting block is fixedly connected to the surface of the pressure roller, with two of each of the first and second limiting blocks.

[0013] The advantages of this utility model are:

[0014] This invention uses a rotating threaded rod to move the threaded ring block and the moving block, which in turn pulls the diamond-shaped telescopic frame to expand or contract. This, in turn, causes multiple adjusting blocks to move synchronously at equal intervals, so that the guide ring blocks at the top of the fixed block, adjusting block, and moving block are evenly separated and the yarn is evenly separated. The yarn can quickly pass through the mounting groove into the interior of the guide ring block, and the elasticity of the spring pushes the baffle to close, preventing the yarn from coming out of the interior of the guide ring block. This effectively reduces the occurrence of yarn entanglement, deviation, and yarn breakage during yarn feeding, and improves the stability of yarn feeding and the uniformity of fabric weaving.

[0022] 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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a yarn feeding device for a circular spinning loom. (Refer to...) Figure 1-5A yarn feeding device for a spinning circular loom includes a yarn feeding base 1, a yarn feeding roller 2 and a pressure roller 3 on one side of the yarn feeding base 1, a connecting frame 4 fixedly connected to the top of the yarn feeding base 1, and an adjustment mechanism 5 on one side of the connecting frame 4.

[0025] The adjusting mechanism 5 includes a threaded rod 51, the surface of which is rotatably connected to the inner cavity of the connecting frame 4. A fixed block 52 is fixedly connected to one side of the connecting frame 4. A threaded ring block 54 is threadedly connected to the surface of the threaded rod 51. A movable block 55 is fixedly connected to the surface of the threaded ring block 54. A diamond-shaped telescopic frame 56 is fixedly connected to the bottom of the fixed block 52 and the movable block 55. A plurality of adjusting blocks 53 are fixedly connected to the top of the diamond-shaped telescopic frame 56. The inner cavities of the plurality of adjusting blocks 53 are all fitted onto the surface of the threaded rod 51. A guide component 57 is provided on the top of the movable block 55, the fixed block 52 and the plurality of adjusting blocks 53. A limit component 58 is provided on one side of the connecting frame 4.

[0026] The limiting component 58 includes a fixed rod 582, both ends of which are fixedly connected to the inner cavity of the connecting frame 4. The inner cavities of the moving block 55 and multiple adjusting blocks 53 are slidably connected to the surface of the fixed rod 582. A limiting plate 581 is fixedly connected to one side of the connecting frame 4.

[0027] The guide assembly 57 includes a guide ring block 571, one side of which is fixedly connected to the top of the fixing block 52, and a rotating ball 572 is movably connected to the inner cavity of the guide ring block 571.

[0028] The yarn feeding base 1 connects the yarn feeding roller shaft 2 and the pressure roller 3. The yarn feeding roller shaft 2 is primarily used to feed the yarn, while the pressure roller 3 presses down on the yarn during feeding to ensure stability during yarn transport. The yarn feeding base 1, yarn feeding roller shaft 2, and pressure roller 3 constitute an important part of the existing yarn feeding structure. When the yarn feeding structure of the circular loom is working, the yarn is drawn from the surface of the yarn feeding roller shaft 2 and guided to the yarn feeding roller cylinder. The pressure roller 3 then presses and limits the yarn, allowing it to enter the weaving area continuously and smoothly, thus providing a continuous and stable yarn supply for the weaving of cylindrical fabrics. The yarn feeding structure is existing technology in this field, therefore its working principle will not be discussed here. To elaborate further, the connecting frame 4 connects the threaded rod 51 and the fixed block 52. The threaded rod 51 is connected to the moving block 55 via the threaded ring block 54. When the threaded rod 51 is rotated, it can drive the moving block 55 to move via the limiting component 58. Simultaneously, the fixed block 52, the moving block 55, and multiple adjusting blocks 53 are all connected to the diamond-shaped telescopic frame 56. The fixed block 52 is fixedly connected to one side of the connecting frame 4, and the multiple adjusting blocks 53 are sleeved on the surface of the threaded rod 51. Therefore, when the threaded rod 51 rotates and drives the moving block 55 to move, the moving block 55 can drive the multiple adjusting blocks 53 to move at equal intervals via the diamond-shaped telescopic frame 56, cooperating with the fixed block 52, adjusting block 53, and moving block 56. The guide component 57 connected to the top of the 5-axis provides even spacing for the yarns, reducing the possibility of multiple yarns tangling. The connecting frame 4 can install the limiting plate 581 and the fixing rod 582. The fixing rod 582 can limit the movement of the moving block 55 and the adjusting block 53 by sliding its connection with the moving block 55 and multiple adjusting blocks 53. At the same time, the inner cavity of the fixing block 52 is fixedly connected to the surface of the fixing rod 582, which can effectively strengthen the connection between the fixing block 52 and the connecting frame 4 through the connection relationship between the fixing rod 582 and the connecting frame 4. The limiting plate 581 can further limit the movement of the adjusting block 53 and the moving block 55, so that the two can move in a controlled manner. When moving, it is not easy to shake or rotate slightly. The top of the multiple adjusting blocks 53 and moving blocks 55 are all provided with guide components 57. The multiple guide components 57 have the same structure, so the working principle of the multiple guide components 57 will not be described in detail here. The fixed block 52 can be connected to the rotating ball 572 through the guide ring block 571. The guide ring block 571 can guide and separate the yarn that needs to be fed. At the same time, the rotating ball 572 can effectively reduce the friction between the yarn surface and the inner cavity of the guide ring block 571 when the yarn is fed through the guide ring block 571 through its movable connection with the guide ring block 571, and at the same time reduce the wear caused to the yarn surface.

[0029] Reference Figure 5The surface of the guide ring block 571 is provided with an installation groove 13. A fixing plate 10 is fixedly connected to the inner cavity of the installation groove 13. A spring 11 is fixedly connected to one side of the fixing plate 10. A baffle 12 is fixedly connected to one end of the spring 11. One side of the baffle 12 is rotatably connected to the inner cavity of the guide ring block 571.

[0030] The guide ring block 571 can be connected to the fixing plate 10 through the mounting groove 13, and the fixing plate 10 can be installed on the baffle 12 through the spring 11. At the same time, the spring 11 can elastically pull the baffle 12. The setting of the mounting groove 13 makes it more convenient for workers to thread the yarn into the guide ring block 571, without having to thread it from one side of the guide ring block 571. The baffle 12 can use the elasticity of the spring 11 to provide a certain shielding effect on the mounting groove 13, so that when the yarn is threaded into the guide ring block 571, it is not easy to move out of the guide ring block 571 through the mounting groove 13.

[0031] Reference Figure 1 Both sides of the connecting frame 4 are rotatably connected to limiting ring blocks 7. The inner cavities of the two limiting ring blocks 7 are fixedly connected to the surface of the threaded rod 51. A guide plate 6 is fixedly connected to one side of the yarn feeding base 1. The guide plate 6 is located between the connecting frame 4 and the pressure roller 3. A first limiting block 8 is fixedly connected to the surface of the yarn feeding roller shaft 2. A second limiting block 9 is fixedly connected to the surface of the pressure roller 3. There are two of each of the first limiting block 8 and the second limiting block 9.

[0032] The limiting ring 7, through its connection with the threaded rod 51 and the connecting frame 4, restricts the connection between the threaded rod 51 and the connecting frame 4, preventing the threaded rod 51 from slipping out, deviating, or falling when rotating inside the connecting frame 4. The guide plate 6 guides the yarn moving out from inside the guide ring 571, allowing it to be smoothly pressed and fed by the pressure roller 3, preventing wear and friction with one side of the yarn feeding base 1. The first limiting block 8 restricts the yarn stored on the surface of the yarn feeding roller shaft 2, preventing the yarn from deviating during feeding. The second limiting block 9 has a similar function to the first limiting block 8, further limiting the yarn pressed by the pressure roller 3, preventing the yarn on both sides from deviating or moving.

[0033] Working principle: When this device is in use, the yarn feeding roller 2 and pressure roller 3 on the yarn feeding base 1 can cooperate to convey the yarn. Before feeding the yarn, the yarn can be threaded into the guide component 57 as needed. During threading, the threaded rod 51 in the connecting frame 4 can be rotated first. The rotation of the threaded rod 51 drives the threaded ring block 54 and the moving block 55 to move. When the moving block 55 moves, it can pull the diamond telescopic frame 56 to unfold, and drive multiple adjusting blocks 53 to move synchronously at equal intervals along the surface of the fixed rod 582, thereby realizing the adjustment of the fixed block 582. 2. Multiple adjusting blocks 53 and the guide ring blocks 571 at the top of the moving block 55 are synchronously separated at equal intervals. After the spacing of the multiple guide ring blocks 571 is separated, the yarn can be quickly inserted into the interior of the guide ring block 571 through the mounting groove 13. At the same time, the spring 11 pushes the baffle 12 to reset and close the mounting groove 13 to prevent the yarn from coming out. After that, the yarn can be fed through the yarn feeding base 1, the yarn feeding roller 2 and the pressure roller 3, thereby effectively reducing the problems of yarn entanglement, deviation, yarn breakage and uneven fabric quality during yarn feeding.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
