[0029] Referring to Figure 1 and Figure 2 , the embodiment provides a yarn guide seat for textile machine, which comprises a base 1, a yarn guide assembly 2 and a yarn transmission assembly 3.

[0030] Referring to Figure 1 , the base 1 is provided with a notch 11, and the sidewall of the base 1 is provided with a plurality of positioning holes 12 penetrating the notch 11, and each positioning hole 12 movably inserts at least one insertion rod.

[0031] The yarn guide assembly 2 is used for guiding the yarn. Specifically, its structure can be a yarn guide wheel 22, a yarn guide hook or the like component, so that the yarn can enter the yarn transmission assembly 3 smoothly and orderly, avoiding problems such as winding and knotting of the yarn during transmission.

[0032] Referring to Figure 1 , the yarn guide assembly 2 and the yarn transmission assembly 3 are sequentially arranged along the feeding direction of the yarn; the yarn transmission assembly 3 comprises a yarn angle adjusting plate 31 and a yarn transmission pipe 32; the yarn transmission pipe 32 is connected with the yarn angle adjusting plate 31 and is used for guiding the yarn to pass through; the yarn angle adjusting plate 31 is movably arranged in the notch 11, and the yarn angle adjusting plate 31 is provided with a plurality of insertion holes 311, and a plurality of insertion rods are detachably inserted into the plurality of insertion holes 311 to adjust the angle of the yarn angle adjusting plate 31. Specifically, the plurality of insertion holes 311 provided on the yarn angle adjusting plate 31 correspond to the positioning holes 12 of the sidewall of the base 1, and the insertion rod is inserted into different combinations of the positioning holes 12 and the insertion holes 311, so as to change the inclination angle of the yarn angle adjusting plate 31, and the position and angle of the yarn transmission pipe 32 will change accordingly with the change of the angle of the yarn angle adjusting plate 31, so as to realize the adjustment of the feeding angle of the yarn.

[0033] Principle of use: when the textile worker needs to adjust the yarn angle, the appropriate combination of positioning holes 12 and insertion holes 311 is selected according to the production process requirements, the insertion rod is pulled out of the current positioning hole 12 and insertion hole 311, and then inserted into the new positioning hole 12 and insertion hole 311, so as to change the height and angle of the yarn angle adjusting plate 31, thereby driving the height and angle of the yarn transmission pipe 32 to change, so as to adjust the yarn angle passing through the yarn transmission pipe 32. When the yarn guide seat for textile machine is in operation, the yarn passes through the yarn guide assembly 2 and the yarn transmission pipe 32 in sequence, so as to realize the stable feeding of the yarn at a specific angle.

[0034] Therefore, the base 1 side wall is provided with a plurality of positioning holes 12 penetrating to the notch 11, the yarn angle adjusting plate 31 is provided with a plurality of insertion holes 311, and a plurality of insertion rods are detachably inserted into the plurality of insertion holes 311, so that the yarn angle adjusting plate 31 can be fixed at different positions and angles, can flexibly adapt to different requirements of various textile processes on the yarn angle, and improves the processing efficiency of the device.

[0035] In the above technical solution, after the insertion rod is inserted into the positioning hole 12 and the insertion hole 311, stable support and positioning can be provided for the yarn angle adjusting plate 31, so that the angle change caused by vibration and other factors is avoided, the accuracy and consistency of yarn guiding are ensured, and the quality stability of the textile product is improved.

[0036] Referring to Figure 2 Further, the yarn conveying assembly 3 further comprises a ball 33, and the yarn conveying pipe 32 is spherically hinged with the yarn angle adjusting plate 31 through the ball 33.

[0037] Specifically, after the coarse adjustment of the yarn conveying angle of the yarn angle adjusting plate 31 is completed, the characteristic of spherical hinge can be used to finely adjust the yarn angle by a small angle, for example, when producing some high-grade fabrics (such as high-grade silk, precision electronic fabric, etc.) with extremely high requirements on the yarn interlacing angle, even a small angle deviation can affect the quality and performance of the fabric. Through this spherical hinge structure, the yarn angle can be accurately adjusted to a smaller unit, so as to improve the flatness, texture definition and overall quality of the fabric.

[0038] Referring to Figure 2 Further, the top of the yarn angle adjusting plate 31 is connected with a support rod 34, the support rod 34 is provided with a spherical groove, the ball 33 is movably embedded in the spherical groove, the support rod 34 is connected with a screw 35, the screw 35 is threadedly connected with the support rod 34, penetrates the groove wall of the spherical groove and can press the ball 33 in the spherical groove.

[0039] Specifically, the spherical groove on the support rod 34 provides an accurate accommodation space for the ball 33, so that the ball 33 can be stably embedded therein and limited to move within a certain range, preventing it from being excessively displaced or falling out during the yarn angle adjustment. When the screw 35 is tightened, it can press the ball 33 in the spherical groove, ensuring the firm and reliable connection between the ball 33 and the yarn angle adjusting plate 31. On the other hand, during the high-speed operation of the textile machine, the yarn will generate a large pulling force and vibration force on the yarn conveying pipe 32. The stable connection of the ball 33 can ensure that the yarn conveying pipe 32 always maintains the correct angle under various external forces, thereby ensuring the stable transmission and accurate guidance of the yarn.

[0040] Referring to Figure 1 and Figure 3Further, the yarn guide assembly 2 comprises a fixed rod 21 and two yarn guide wheels 22; the fixed rod 21 is arranged on the base 1, and the two yarn guide wheels 22 are pivotally connected with the fixed rod 21 and sequentially arranged along the height direction, and the circumferential side wall of the yarn guide wheel 22 is provided with an annular groove 221, and the two annular grooves 221 are oppositely arranged and constitute a through hole 222 for the yarn to pass through.

[0041] Specifically, the oppositely arranged annular grooves 221 on the circumferential side wall of the two yarn guide wheels 22 constitute the through hole 222 for the yarn to pass through, so that the yarn can be accurately positioned on the set feeding route when passing through the yarn guide assembly 2. Compared with simple yarn guide hooks or flat yarn guide wheels 22, the annular grooves 221 can effectively prevent the yarn from shifting left and right or jumping up and down during transmission, thereby improving the stability of yarn feeding; the inner wall of the annular groove 221 can be designed as a smooth curved surface to reduce the frictional resistance between the yarn and the yarn guide wheel 22, so that the yarn can run more smoothly in the groove, thereby reducing the yarn breakage caused by friction and reducing the wear of the yarn guide wheel 22, prolonging the service life of the equipment.

[0042] Further, the yarn guide assembly 2 further comprises an adjusting assembly connected with at least one yarn guide wheel 22, and the adjusting assembly is used to adjust the distance between the two yarn guide wheels 22.

[0043] Specifically, by adjusting the distance between the two yarn guide wheels 22 through the adjusting assembly, appropriate accommodation space can be provided according to different types and specifications of yarns, so that the yarn guide seat can adapt to the textile demand of various yarn specifications from roving to fine yarn, thereby improving the versatility of the equipment and reducing the trouble of frequently replacing the yarn guide assembly 2 due to the change of yarn specifications.

[0044] Referring to Figure 3 Further, the adjusting assembly comprises a positioning block 23, a transmission screw 24, a transmission block 25 and a guide rod 26; the positioning block 23 is fixedly connected with the fixed rod 21, the transmission screw 24 is coaxially connected with the fixed rod 21, the transmission block 25 is threadedly connected with the transmission screw 24 and movably sleeved with the guide rod 26, and the guide rod 26 is fixedly connected with the positioning block 23 and arranged in parallel with the transmission screw; the upper yarn guide wheel 22 is pivotally connected with the transmission block 25, and the lower yarn guide wheel 22 is pivotally connected with the positioning block 23.

[0045] Specifically, the threaded connection between the transmission screw 24 and the transmission block 25 realizes accurate adjustment of the distance between the yarn guide wheels 22; rotating the transmission screw 24, the transmission block 25 will move linearly along the axial direction of the screw to realize high transmission accuracy, so as to accurately control the distance between the yarn guide wheels 22 to meet the requirements of high-precision process, thereby improving the quality and performance of the fabric.

[0046] Referring to Figure 1Preferably, the side wall of the base 1 is fixedly connected with a plurality of tension springs 13, one end of each of the tension springs 13 away from the base 1 is fixedly connected with a pull handle 14, one of the plurality of tension springs 13 is correspondingly provided with one of the positioning holes 12, and a plurality of insertion rods are fixed to the pull handle 14 and are correspondingly sleeved with the plurality of tension springs 13.

[0047] Specifically, when it is necessary to adjust the angle of the yarn angle adjusting plate 31, the operator only needs to hold the pull handle 14 and pull, and through the elastic deformation of the tension spring 13, the insertion rod can be pulled out of the current positioning hole 12, without the need of using an additional tool or exerting excessive force, the insertion and extraction operation of the insertion rod can be easily completed, compared with the traditional way of manually inserting and extracting the insertion rod one by one and possibly with the help of pliers and other tools, the design simplifies the operation process of angle adjustment and improves the convenience and efficiency of operation.

[0048] Preferably, the base 1 is connected with a protection plate, and the protection plate is located directly above the tension spring 13.

[0049] Specifically, in the textile process, the yarn is in a dynamic transmission state and may deviate or swing due to various reasons (such as airflow, vibration, yarn breakage, etc.), which may cause the yarn to contact and wind around the tension spring 13, block the transmission of the yarn, even possibly break the yarn, and affect the continuity of textile production. The arrangement of the protection plate avoids the problem of yarn winding around the tension spring 13 and improves the safety of the equipment.
