Description

Technical Field

[0001] This utility model relates to the field of rapier loom technology, and in particular to a yarn bobbin placement device for rapier looms. Background Technology

[0002] The rapier loom is a highly efficient shuttleless loom that uses rapiers (rigid or flexible clamping devices) to guide the weft yarn between the warp yarns for weaving. Its main function is to weave various textile fabrics, and it is widely used in the production of cotton, wool, linen, silk, and synthetic fibers. Compared to traditional shuttle looms, rapier looms offer advantages such as higher speed, lower noise, greater weft yarn adaptability, and higher fabric quality, meeting the needs of large-scale industrial production and making it one of the essential pieces of equipment in the modern textile industry.

[0003] The yarn bobbins of a rapier loom typically have a tubular structure and are used to carry and supply weft or warp yarns, ensuring a stable yarn supply even at high speeds. The bobbins are usually mounted on a yarn frame and guided into the weaving area by yarn guiding mechanisms (such as guide rods or guide wheels). Their main function is to provide a uniform yarn supply to guarantee weaving quality and production efficiency.

[0004] However, existing yarn bobbin placement devices typically use a fixed installation method, which prevents flexible adjustment of yarn bobbins of different specifications, requiring frequent component replacements and impacting production efficiency. Furthermore, traditional yarn bobbin clamping mechanisms are mostly designed with a single size, making it difficult to adapt to yarn bobbin rotating rods of different diameters. The fixing methods are also relatively simple, making them prone to loosening or shifting during high-speed operation. On the other hand, existing devices have limited measures for static electricity elimination, allowing static electricity to easily accumulate in the yarn during high-speed transport, leading to tangling or poor yarn feeding, thus affecting weaving quality.

[0005] To address the above issues, a yarn bobbin placement device for rapier looms is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a yarn bobbin placement device for rapier looms, aiming to solve the problems of insufficient flexibility in adapting to yarn bobbins of different specifications, poor stability of yarn bobbin clamping by the yarn bobbin rotating rod, and the impact of static electricity accumulation on yarn supply stability of existing yarn bobbin placement devices for rapier looms.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a yarn bobbin placement device for a rapier loom, including a base, two support plates symmetrically arranged on the top of the base, a yarn bobbin and an electrostatic brush being rotatably connected between the two support plates, and an adjustment mechanism being provided inside the support plates;

[0008] The adjustment mechanism includes a limiting component, a locking component, and rotating beads. The limiting component includes a limiting block. The rotating beads are evenly distributed on the bottom inner arc surface of the limiting block. The limiting block is slidably connected to the inside of the support plate. Side plates are fixedly connected to both sides of the limiting block. A sliding groove is provided on both sides of the inside of the support plate. A tension spring is provided inside the sliding groove. The side plates are slidably connected to the inside of the sliding groove.

[0009] As a further description of the above technical solution:

[0010] The top of the tension spring is fixedly connected to the bottom of the side plate, and the bottom of the tension spring is fixedly connected to the bottom wall of the slide groove.

[0011] As a further description of the above technical solution:

[0012] The support plate has sliders fixedly connected to both sides of its bottom, and the base has a bottom groove. The sliders are slidably connected inside the bottom groove, and the sliders are connected to the base by fixing bolts.

[0013] As a further description of the above technical solution:

[0014] The locking assembly includes a pin, a force-bearing plate is fixedly connected to the middle of the pin, and a tension spring is sleeved on the outer side of the pin.

[0015] As a further description of the above technical solution:

[0016] The limiting block has an inner groove, and the force-bearing plate is slidably connected inside the inner groove.

[0017] As a further description of the above technical solution:

[0018] The top of the second tension spring is fixedly connected to the bottom of the force-bearing plate, and the bottom of the second tension spring is fixedly connected to the inner bottom wall of the inner groove.

[0019] As a further description of the above technical solution:

[0020] The pin has a handle at its top and is slidably connected inside the limiting block.

[0021] As a further description of the above technical solution:

[0022] The yarn bobbin has a rotating shaft inside, with its two ends located inside the two support plates, and the bottom of the pin is inserted into the rotating shaft.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, two sliding bases allow the yarn bobbin to move on the bases to accommodate yarn bobbins of different specifications. The bobbins are secured with bolts to ensure stability and prevent loosening during operation. This improves the versatility of the equipment and reduces the frequency of component replacements due to different yarn bobbin specifications.

[0025] 2. In this utility model, in order to improve the compatibility of the equipment with yarn bobbin rotating rods of different diameters, the clamping block adopts an elastic clamping mechanism and a pin locking assembly. The tension spring controls the limiting block to clamp the yarn bobbin rotating shaft, while the pin locking assembly fixes the yarn bobbin by driving the pin through the tension spring, ensuring stable support of the rotating rod.

[0026] 3. In this invention, during high-speed weaving, yarn friction easily accumulates static electricity, leading to problems such as yarn tangling and poor yarn supply. By installing an electrostatic brush and a grounding device, the yarn releases its charge as it passes through, further reducing the impact of static electricity. This improves the stability of yarn supply, helps reduce yarn breakage, and enhances weaving quality. Attached Figure Description

[0033] 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.

[0034] Reference Figures 1-2 This utility model provides an embodiment of a yarn bobbin placement device for a rapier loom, comprising a base 1 for supporting and securing the stable operation of the entire device. Two support plates 2 are symmetrically arranged on the top of the base 1, with a yarn bobbin 5 rotatably connected between them via a rotating shaft structure. This ensures smooth rotation of the yarn bobbin 5 during operation, providing a stable yarn supply. An electrostatic brush 3 is installed near the yarn bobbin 5 to eliminate static electricity and prevent the yarn from tangling or breaking due to electrostatic attraction. To improve the adaptability and stability of the device, an adjustment mechanism 4 is provided inside the support plates 2. This mechanism can adjust the clamping state of the yarn bobbin 5's rotating shaft to accommodate yarn bobbins 5 of different diameters, ensuring the yarn bobbin 5 is firmly fixed and remains stable during operation. To enhance the versatility of the device, sliders 21 are fixedly connected to both sides of the bottom of the support plates 2, and a bottom groove 11 is provided inside the base 1. The sliders 21 can slide along the bottom groove 11, thereby adjusting the spacing of the support plates 2 to meet the installation requirements of yarn bobbins 5 of different specifications. After being adjusted to the appropriate position, the slider 21 is connected to the base 1 by the fixing bolt 6 to ensure that the adjusted position is stable and will not loosen or shift during the operation of the loom, thereby improving the stability and reliability of the yarn supply of the yarn cylinder 5.

[0035] Reference Figures 2-3The adjustment mechanism 4 includes a limiting component 41, a locking component 42, and rotating beads 43, used to achieve stable clamping and flexible adjustment of the yarn bobbin 5's rotating shaft to adapt to yarn bobbins 5 of different specifications. The limiting component 41 includes a limiting block 411, and the rotating beads 43 are evenly distributed on the bottom inner arc surface of the limiting block 411, allowing the limiting block 411 to more smoothly fit and clamp the rotating shaft of the yarn bobbin 5 with different diameters, improving the compatibility and adaptability of the device. The limiting block 411 is slidably connected inside the support plate 2, and side plates 412 are fixedly connected to both sides of the limiting block 411. To ensure that the limiting block 411 can move along a set trajectory during adjustment, a sliding groove 414 is provided on both sides of the inside of the support plate 2. This sliding groove 414 is used to guide the side plates 412 to slide inside it, ensuring that the movement direction of the limiting block 411 is controlled, thereby ensuring adjustment accuracy. To further enhance the reliability of clamping, a tension spring 413 is also installed inside the slide groove 414 to provide a rebound force, enabling the limit block 411 to automatically reset or apply a constant clamping force. The top of the tension spring 413 is fixedly connected to the bottom of the side plate 412, while its bottom is fixedly connected to the bottom wall of the slide groove 414. This ensures that the tension spring 413 provides a stable rebound effect under stress, allowing the limit block 411 to quickly reset after the yarn bobbin 5 is replaced or adjusted, thereby improving the operational stability and service life of the equipment.

[0036] Reference Figure 2 and Figure 4The locking assembly 42 is used to reliably fix the shaft of the yarn bobbin 5, ensuring that the yarn bobbin 5 will not shake or loosen during high-speed rotation. The locking assembly 42 includes a pin 422, which has a handle 421 on its top for easy manual unlocking or locking by the operator. The pin 422 is slidably connected inside the limiting block 411 and can move up and down inside the limiting block 411. To enhance the stability of the lock, a force plate 423 is fixedly connected to the middle of the pin 422. The force plate 423 provides additional structural support and ensures that the pin 422 moves smoothly during locking or unlocking. To accommodate the sliding requirements of the pin 422, an inner groove 425 is provided inside the limiting block 411. This inner groove 425 is used to accommodate the force plate 423, allowing it to slide smoothly inside the inner groove 425 while maintaining the same direction of movement of the pin 422. To provide an automatic return function, a tension spring 424 is fitted on the outer side of the pin 422. The top of the tension spring 424 is fixedly connected to the bottom of the force plate 423, while its bottom is fixedly connected to the inner bottom wall of the inner groove 425. This allows the pin 422 to automatically spring back to the locked position after unlocking, improving the reliability of the yarn bobbin 5. A rotating shaft is installed inside the yarn bobbin 5, with both ends located inside the two support plates 2, forming a stable rotational support structure. When the pin 422 is in the locked state, its bottom is inserted into the rotating shaft, achieving a stable clamping of the yarn bobbin 5 and preventing it from loosening or falling off due to vibration or external forces during operation, thereby improving the operational stability and service life of the equipment.

[0037] Working principle: When the yarn bobbin 5 is installed between the support plates 2, the two ends of the rotating shaft of the yarn bobbin 5 are respectively placed in the arc-shaped area inside the two limiting blocks 411. The rotating beads 43 are evenly distributed on the bottom inner arc surface of the limiting blocks 411, so that the rotating shaft can smoothly fit on the limiting blocks 411. The limiting blocks 411 are slidably connected to the inside of the first groove 414 through the side plate 412, and provide a certain clamping force under the action of the first tension spring 413. At the same time, they can be adjusted according to the specifications of the yarn bobbin 5. The limiting block 411 has an inner groove 425 inside, and the pin 422 is slidably connected to the inside of the limiting block 411 and moves up and down along the inner groove 425 under the guidance of the force plate 423. The outer side of the pin 422 is fitted with a second tension spring 424. The top of the second tension spring 424 is fixed to the bottom of the force plate 423, and the bottom is fixed to the inner bottom wall of the inner groove 425, so that the pin 422 can automatically reset after being released. After the yarn bobbin 5 is installed in place, the operator releases handle 421. Driven by tension spring 424, the bottom of pin 422 inserts into the rotating shaft, thus locking the yarn bobbin 5 and ensuring its stable fixation. When the yarn bobbin 5 needs to be replaced, the operator pulls handle 421 to disengage pin 422 from the rotating shaft, releasing the lock. Slider blocks 21 are fixedly connected to both sides of the bottom of support plate 2. These sliders 21 are slidably connected in the bottom groove 11 inside base 1 and are locked in position by fixing bolts 6, allowing the spacing of support plate 2 to be adjustable to accommodate yarn bobbins 5 of different lengths. An anti-static brush 3 is installed near the yarn bobbin 5 to reduce static electricity during yarn transport.
