Description
Technical Field
[0001] This utility model belongs to the field of textile machinery technology, specifically relating to a guide angle iron weft-blocking column device. Background Technology
[0002] In the textile industry, Dornier looms are commonly used weaving equipment, and their guide scissors play an important role in the weaving process. However, the existing Dornier loom guide scissors weft-blocking design has defects. During use, the guide scissors weft-blocking posts are easily worn off or have gaps worn out by the weft yarns. This can damage the weft yarn surface and affect the fabric quality, or even cause the posts to fall off, making normal weaving impossible, or even fall into the weaving area, causing equipment accidents and causing great trouble and losses to production.
[0003] Most existing weaving devices use a fixed connection method to set up weft blocking columns. However, since their position cannot be adjusted, the weft yarn comes into direct contact with the column and generates friction. After long-term use, wear problems are very likely to occur, making it difficult to meet the needs of long-term stable production.
[0004] To address this issue, a guide angle iron weft-blocking column device was designed. Utility Model Content
[0005] To address the problems mentioned in the background section, this invention provides a guide angle iron weft-blocking column device. This device allows adjustment of the horizontal position of the weft-blocking column according to the weft yarn direction and weaving requirements, preventing direct contact between the weft yarn and the column, reducing wear risk from the source, improving the device's adaptability to different weaving conditions, and enabling precise adjustment of the weft-blocking column angle. This minimizes the friction area and intensity between the weft yarn and the column, adapting to different types of weft yarns and weaving processes, and improving the equipment's versatility.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a guide angle iron weft-blocking column device, comprising a guide angle iron body and a weft-blocking column disposed on one side of the guide angle iron body, and further comprising a sliding adjustment component disposed on the surface of the guide angle iron body;
[0007] The sliding adjustment assembly includes a slide rail fixedly connected to the surface of the guide angle iron body, a sliding block slidably connected to the surface of the slide rail, and the weft-blocking column is disposed above the sliding block.
[0008] As a preferred embodiment of the guide angle iron weft-blocking column device of this utility model, the surface of the slide rail is symmetrically provided with positioning holes, and the surface of the sliding block is provided with locking bolts, which are slidably connected to the slide rail through the positioning holes.
[0009] In a preferred embodiment of the guide angle iron weft-blocking column device of this utility model, the locking bolt and the sliding block are threadedly connected.
[0010] As a preferred embodiment of the guide angle iron weft-blocking column device of this utility model, it further includes an angle adjustment component disposed above the guide angle iron body. The angle adjustment component includes a connecting seat connected to the surface of the sliding block. A sleeve is slidably connected to the surface of the connecting seat, and the sleeve is fixedly connected to the weft-blocking column.
[0011] As a preferred embodiment of the guide angle iron weft-blocking column device of this utility model, the surface of the connecting seat is symmetrically provided with limiting grooves, and the surface of the sleeve is symmetrically fixedly connected with limiting blocks. The limiting blocks are slidably connected to the connecting seat through the limiting grooves.
[0012] As a preferred embodiment of the guide angle iron weft-blocking column device of this utility model, a worm gear is rotatably connected inside the casing, a half-worm wheel is fixedly connected to the surface of the connecting seat, the half-worm wheel and the worm gear are meshed and connected, and one end of the worm gear passes through the surface of the casing and is fixedly connected to a knob.
[0013] As a preferred embodiment of the guide angle iron weft-blocking column device of this utility model, the surface of the weft-blocking column is provided with a wear-resistant sleeve.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] By using the sliding adjustment component's slide rail and sliding block, the horizontal position of the weft-blocking column can be adjusted according to the weft yarn direction and weaving requirements, avoiding direct contact between the weft yarn and the column, reducing the risk of wear from the source, and improving the device's adaptability to different weaving conditions. The positioning holes on the slide rail and the locking bolts on the sliding block are matched, and the locking bolts and the sliding block are connected by threads, which can firmly fix the adjusted sliding block and prevent the position from shifting due to vibration during weaving. It takes into account both adjustment flexibility and working stability, while the symmetrical design makes the force more even.
[0016] The angle adjustment component achieves precise adjustment of the weft-blocking column angle through the sliding fit between the connecting seat and the housing, combined with the meshing transmission of the worm gear and the semi-worm wheel. This minimizes the friction area and intensity between the weft yarn and the column, adapts to different types of weft yarns and weaving processes, and improves the equipment's versatility.

[0028] 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. Embodiment 1
[0029] Most existing weaving devices use fixed connections to set up weft blocking columns. However, since their positions cannot be adjusted, the weft yarns come into direct contact with the columns and rub against them. This can easily lead to wear and tear after long-term use, making it difficult to meet the needs of long-term stable production. Therefore, a guide angle iron weft blocking column device is designed to solve the above problems.
[0030] Furthermore:
[0031] like Figures 1 to 4 As shown:
[0032] Based on the above: A sliding adjustment component 3 is provided on the surface of the guide angle iron body 1. The sliding adjustment component 3 includes a slide rail 31 fixedly connected to the surface of the guide angle iron body 1, a sliding block 32 slidably connected to the surface of the slide rail 31, and a weft-blocking column 2 is provided above the sliding block 32.
[0033] In this implementation scheme: by sliding the sliding block 32 on the slide rail 31, the weft-blocking column 2 can be moved along the direction of the slide rail 31, thereby adjusting the horizontal position of the weft-blocking column 2. This realizes the position adjustment function of the weft-blocking column 2, breaking through the design limitation of the traditional fixed and non-adjustable weft-blocking column 2. By sliding adjustment, the horizontal position of the weft-blocking column 2 can be changed according to the weft yarn direction and weaving requirements, avoiding direct contact between the weft yarn and the weft-blocking column 2, fundamentally reducing the risk of wear and improving the adaptability of the equipment.
[0034] Furthermore:
[0035] like Figures 1 to 4 As shown:
[0036] In an optional embodiment, the surface of the slide rail 31 is symmetrically provided with positioning holes 33, and the surface of the sliding block 32 is provided with locking bolts 34, which are slidably connected to the slide rail 31 through the positioning holes 33.
[0037] In this embodiment, by setting a positioning hole 33 on the slide rail 31 and cooperating with the locking bolt 34 on the sliding block 32, the function of fixing the sliding position is realized, ensuring that the weft-blocking column 2 can be stably fixed after being adjusted to a suitable position, avoiding position displacement caused by vibration and other factors during the weaving process, thus ensuring both adjustment flexibility and working stability.
[0038] Furthermore:
[0039] like Figures 1 to 4 As shown:
[0040] In an optional embodiment, the locking bolt 34 and the sliding block 32 are threaded together.
[0041] In this embodiment, the connection between the locking bolt 34 and the sliding block 32 is specified as a threaded connection, which facilitates the operator to quickly tighten or loosen the sliding block 32, improves the efficiency of position adjustment, and ensures that the tightening force is controllable to adapt to different working environment requirements.
[0042] Furthermore:
[0043] like Figures 1 to 4 As shown:
[0044] In an optional embodiment, an angle adjustment component 4 is also provided above the guide angle iron body 1. The angle adjustment component 4 includes a connecting seat 41 connected to the surface of the sliding block 32. A sleeve 42 is slidably connected to the surface of the connecting seat 41. The sleeve 42 is fixedly connected to the weft-blocking column 2.
[0045] In this embodiment: the angle of the weft-blocking column 2 can be adjusted by the sliding fit between the connecting seat 41 and the sleeve 42, and the sleeve 42 and the weft-blocking column 2 are fixed as one piece, realizing the dual adjustment of the "position + angle" of the weft-blocking column 2. The contact angle between the weft-blocking column 2 and the weft yarn can be precisely adjusted to minimize the friction area and friction intensity.
[0046] Furthermore:
[0047] like Figures 1 to 4 As shown:
[0048] In an optional embodiment, the surface of the connecting seat 41 is symmetrically provided with limiting grooves 44, and the surface of the housing 42 is symmetrically fixedly connected with limiting blocks 43. The limiting blocks 43 are slidably connected to the connecting seat 41 through the limiting grooves 44.
[0049] In this implementation scheme: symmetrical limiting grooves 44 are opened on the surface of the connecting seat 41, and limiting blocks 43 are correspondingly set on the surface of the housing 42. The limiting blocks 43 are embedded in the limiting grooves 44 and can slide along the limiting grooves 44, thereby guiding the sliding of the housing 42 relative to the connecting seat 41 and limiting the angle adjustment range, avoiding jamming or offset during adjustment, preventing over-adjustment from damaging the equipment or affecting the weaving quality, and improving the safety and reliability of angle adjustment.
[0050] Furthermore:
[0051] like Figures 1 to 4 As shown:
[0052] In an optional embodiment, a worm gear 46 is rotatably connected inside the housing 42, and a half-worm wheel 45 is fixedly connected to the surface of the connecting seat 41. The half-worm wheel 45 and the worm gear 46 are meshed together. One end of the worm gear 46 passes through the surface of the housing 42 and is fixedly connected to a knob 47.
[0053] In this embodiment: the worm 46 meshes with the half worm wheel 45, one end of the worm 46 passes through the casing 42 and is connected to the knob 47. By rotating the knob 47, the worm 46 is driven to rotate. The angle adjustment of the casing 42 (and the weft-blocking column 2) is achieved by the meshing transmission between the worm 46 and the half worm wheel 45.
[0054] Furthermore:
[0055] like Figures 1 to 4 As shown:
[0056] In an optional embodiment, the surface of the weft-blocking column 2 is provided with a wear-resistant sleeve 5.
[0057] In this embodiment, a wear-resistant sleeve 5 is provided on the surface of the weft-blocking column 2. The wear-resistant sleeve 5 is sleeved on the outside of the weft-blocking column 2 and directly contacts the weft yarn. The wear-resistant sleeve 5 can be made of highly wear-resistant materials (such as ceramics, hard alloys, etc.) and can directly withstand the friction of the weft yarn, effectively protecting the body of the weft-blocking column 2 from wear. The wear-resistant sleeve 5 can be disassembled and replaced separately, reducing the maintenance cost of the equipment, extending the service life of the entire device, and achieving the "permanent non-wearing" effect in the improvement goal.
[0058] Working principle: By sliding the sliding block 32 on the slide rail 31, the weft-blocking column 2 can be moved along the direction of the slide rail 31, thereby adjusting the horizontal position of the weft-blocking column 2. This realizes the adjustable position function of the weft-blocking column 2, breaking through the design limitation of the traditional fixed and non-adjustable weft-blocking column 2. Through sliding adjustment, the horizontal position of the weft-blocking column 2 can be changed according to the weft yarn direction and weaving requirements, avoiding direct contact between the weft yarn and the weft-blocking column 2, fundamentally reducing the risk of wear and improving the adaptability of the equipment. By setting the positioning hole 33 on the slide rail 31, and cooperating with the locking bolt 34 on the sliding block 32, the function of fixing the sliding position is realized. To ensure the stable fixation of the weft-blocking column 2 after adjustment to the appropriate position, preventing positional displacement due to vibration or other factors during weaving, this design balances adjustment flexibility with operational stability. The connection between the locking bolt 34 and the sliding block 32 is a threaded connection, facilitating quick tightening or loosening of the sliding block 32 by operators, improving position adjustment efficiency, and ensuring controllable tightening force to adapt to different working environments. The angle adjustment of the weft-blocking column 2 is achieved through the sliding engagement of the connecting seat 41 and the housing 42, with the housing 42 and the weft-blocking column 2 fixed as a single unit, realizing dual adjustment of the weft-blocking column 2's "position + angle". The section allows for precise adjustment of the contact angle between the weft blocking column 2 and the weft yarn, minimizing the friction area and intensity. Symmetrical limiting grooves 44 are formed on the surface of the connecting seat 41, and corresponding limiting blocks 43 are provided on the surface of the housing 42. The limiting blocks 43 are embedded in the limiting grooves 44 and can slide along them, guiding the sliding of the housing 42 relative to the connecting seat 41 and limiting the angle adjustment range. This prevents jamming or offset during adjustment, avoids over-adjustment that could damage the equipment or affect weaving quality, and improves the safety and reliability of angle adjustment. A worm gear 46 meshes with a semi-worm wheel 45, with one end of the worm gear 46 penetrating the housing 42 and connected to a knob 47. The worm gear 46 is rotated by rotating the knob 47. The angle of the sleeve 42 (and the weft-blocking column 2) is adjusted by the meshing transmission between the worm gear 46 and the half-worm wheel 45. The surface of the weft-blocking column 2 is provided with a wear-resistant sleeve 5. The wear-resistant sleeve 5 is sleeved on the outside of the weft-blocking column 2 and is in direct contact with the weft yarn. The wear-resistant sleeve 5 can be made of highly wear-resistant materials (such as ceramics, hard alloys, etc.) and can directly withstand the friction of the weft yarn, effectively protecting the body of the weft-blocking column 2 from wear. The wear-resistant sleeve 5 can be disassembled and replaced separately, which reduces the maintenance cost of the equipment, extends the service life of the entire device, and achieves the "permanent non-wear" effect in the improvement goal.
