Description

Technical Field

[0001] This utility model relates to the field of textile weft insertion technology, specifically an adjustable weft insertion device for textile looms. Background Technology

[0002] Beating in the weft is the core process in weaving where the weft yarn is pushed into the weft hole to form the fabric. It directly affects the fabric density, texture clarity, and finished product quality. The beating in the weft mechanism pushes the weft yarn towards the weft hole through reciprocating motion, where it interweaves with the warp yarn to form a stable fabric structure. This process requires precise control of the weft yarn position, which directly affects the fabric width tolerance and fabric surface flatness. It includes two stages: the advancing stage and the retreating stage. In the advancing stage, the beating rod accelerates forward from the rear stop point to complete the weft yarn positioning, while in the retreating stage, it returns to the starting position to leave operating space for the next beating in the weft.

[0003] However, the steel reeds used for weft insertion are currently fixed in place, making it impossible to adjust the angle according to different types of fabrics, which is inconvenient to operate. Therefore, this utility model provides an adjustable weft insertion device for textile looms to meet people's needs. Utility Model Content

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] Example: Figure 1-4As shown, this utility model provides a technical solution: an adjustable weft insertion device for a textile loom, including a weft insertion shaft 1, with arc-shaped bonding blocks 2 attached to both ends of the top of the weft insertion shaft 1, a fixed seat 3 connected to the middle of the top of each of the two arc-shaped bonding blocks 2, a connecting rod 4 attached to one end of each of the two fixed seats 3, a reed 5 installed between the tops of the two connecting rods 4, and an angle adjustment mechanism 6 provided in the middle of the fixed seat 3.

[0031] The angle adjustment mechanism 6 includes a mounting groove 601, a rotating shaft 602, a rotating gear 603, a rotating block 604, an angle scale line 605, a comparison bar 606, a limit block 607, a locking screw 608, and a limit insert 609.

[0032] A mounting groove 601 is provided in the middle of the fixed base 3. A rotating shaft 602 is installed through the middle of the mounting groove 601. A rotating gear 603 is fixedly installed in the middle of the rotating shaft 602. The rotating gear 603 is located inside the mounting groove 601. One end of the rotating shaft 602 is fixedly connected to the connecting rod 4. A rotating block 604 is connected to one end of the rotating shaft 602. Angle scale lines 605 are equidistantly provided on the surface of the rotating block 604 along the circumferential direction. A comparison strip 606 is installed at one end of the fixed base 3 at a position corresponding to the rotating block 604. The rotating block 604 is located on the outside of the fixed base 3. The comparison strip 606 is in close contact with the top surface of the rotating block 604.

[0033] A limiting block 607 is fitted to the center of one end of the fixed base 3. Locking screws 608 are installed through the top and bottom of the limiting block 607. A limiting insert 609 is fixedly connected to the center of one end of the limiting block 607. The locking screws 608 are movably inserted into the interior of the fixed base 3. One end of the limiting insert 609 extends into the interior of the mounting groove 601. The end of the limiting insert 609 is inserted into the gap between the teeth of the rotating gear 603. The rotating shaft 602 and the rotating block 604 cooperate to adjust the angle between the connecting rod 4 and the reed 5. The angle can be adjusted easily, and the angle can be compared with the angle scale line 605 and the comparison bar 606 to provide auxiliary reference for the adjusted angle, which effectively improves the accuracy of the adjustment. At the same time, the locking screw 608 and the limit block 607 cooperate to lock and fix the limit plug 609, so as to limit and stabilize the rotating gear 603, improve the stability of the rotating shaft 602 and the rotating block 604, and prevent the rotating shaft 602 and the connecting rod 4 from deflecting and shaking after the adjustment, which would cause the angle to change and affect the normal weft beating operation.

[0034] The two ends of the weft insertion shaft 1 are equipped with convenient installation mechanisms 7;

[0035] The convenient installation mechanism 7 includes a splicing groove 701, a buffer pad 702, a splicing block 703, an external thread 704, a locking sleeve 705, a pressure pad 706, and an auxiliary notch 707;

[0036] Both ends of the weft insertion shaft 1 have splicing grooves 701. A buffer pad 702 is embedded in the bottom of the splicing groove 701. A splicing block 703 is connected to the bottom of the arc-shaped fitting block 2. External threads 704 are formed at one side of the splicing groove 701 at both ends of the weft insertion shaft 1. Locking sleeves 705 are fitted onto both ends of the weft insertion shaft 1. A pressure pad 706 is fixedly connected to one end of the locking sleeve 705. Auxiliary notches 707 are symmetrically formed on the surface of the locking sleeve 705. The splicing block 703 is movably embedded into the splicing groove 701. Internal threads are formed on the inner wall of the locking sleeve 705. 705 is connected to the weft insertion shaft 1 through the engagement of internal and external threads 704. The locking sleeve 705 covers the surface of the splicing block 703. The pressure pad 706 is tightly fitted to one end of the arc-shaped fitting block 2. The splicing groove 701 and the splicing block 703 cooperate with each other to splice the arc-shaped fitting block 2 and the fixing seat 3 with the weft insertion shaft 1. The locking sleeve 705 plays a limiting and wrapping role for the splicing block 703, which improves the connection strength between the splicing block 703 and the weft insertion shaft 1 and prevents the splicing block 703 from falling off. The splicing and installation method is simple and provides great convenience for workers to install and disassemble the reed 5.

[0037] The buffer pad 702 provides compression and stability to the splicing block 703. The deformation elasticity of the buffer pad 702 after being compressed works in conjunction with the wrapping of the locking sleeve 705 to clamp and fix the splicing block 703, improving its stability and preventing it from shaking inside the splicing groove 701. At the same time, the pressure pad 706 increases the friction between the pad and the arc-shaped fitting block 2, making the installation of the locking sleeve 705 more stable. The auxiliary notch 707 makes it easier for workers to rotate the locking sleeve 705.

[0038] The working principle and usage process of this utility model are as follows: First, the worker takes the reed 5 and the fixing base 3 and splices and fixes them with the weft insertion shaft 1. The splicing block 703 is embedded into the splicing groove 701, and the arc-shaped fitting block 2 is tightly attached to the surface of the weft insertion shaft 1. The splicing block 703 is pressed inward, so that the buffer pad 702 is compressed and deformed, while keeping the surface of the arc-shaped fitting block 2 flush with the surface of the weft insertion shaft 1. The locking sleeve 705 is then taken and fitted onto both ends of the weft insertion shaft 1. The surface is rotated and engaged with the external thread 704 until the locking sleeve 705 is fitted onto the surface of the splicing block 703, and the pressure pad 706 is pressed against one end surface of the arc-shaped bonding block 2. When the splicing block 703 is released, the elastic deformation ability of the buffer pad 702 will generate an outward pushing force on the splicing block 703, which cooperates with the limiting of the locking sleeve 705 to make the installation of the splicing block 703 more stable, and thus the reed 5 is fixed on the top of the weft shaft 1;

[0039] If different fabrics need to be woven, the angle of the reed 5 needs to be adjusted. First, tighten the locking screw 608 to remove the limiting block 607 and the limiting insert 609, and no longer limit the rotation gear 603. The operator holds the rotating block 604 to adjust the angle of the rotating shaft 602 and the rotating gear 603. During the adjustment, the comparison strip 606 and the angle scale line 605 work together to provide the operator with an angle auxiliary reference for adjusting the angle, which improves the accuracy of the adjustment. After the adjustment is completed, insert the end of the limiting insert 609 into the mounting groove 601. One end of the limiting insert 609 is embedded in the meshing gap of the rotating gear 603, which plays a role in limiting and stabilizing the rotating gear 603 and the rotating shaft 602. Then, use the locking screw 608 to lock and fix the limiting block 607.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
