Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and more specifically, to a yarn guiding and conveying device for rib fabric. Background Technology

[0002] The textile production of rib fabric is usually accomplished by textile machinery, with flat knitting machines being a common type. Flat knitting machines can better control the interlacing of loops to form a rib structure. During the operation of a flat knitting machine, yarn guiding and conveying equipment, namely yarn guiding and conveying frame, is mainly used to guide and convey the yarn in conjunction with the flat knitting machine.

[0003] Existing yarn guide conveyors typically only guide the yarn bobbins and then pull them directly to the flat knitting machine's working area for weaving. During this process, yarn deviation is prone to occur, which can lead to inaccurate yarn feeding positions during knitting. When weaving rib fabric, the rib is formed by the regular interweaving of different yarns. If the yarn position is deviated, the rib pattern will have inconsistent widths. In view of this, we propose a yarn guide conveyor for rib fabric. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a yarn guiding and conveying device for rib fabrics to solve the technical problem that the current yarn guiding and conveying frame is not convenient for precise adjustment of the yarn conveying angle.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a yarn guiding and conveying device for rib fabric, including a base, a plurality of equidistant yarn bobbin placement racks arranged on the top of the base, a first mounting frame arranged on the top of the base, a first through hole corresponding to the yarn bobbin placement rack on the top of the first mounting frame, a first yarn guide wheel corresponding to the first through hole arranged on the top of the first mounting frame, a mounting plate corresponding to the first yarn guide wheel arranged on one side of the top of the first mounting frame, a second through hole arranged on the top of the mounting plate at the end opposite to the first mounting frame, a second yarn guide wheel corresponding to the second through hole arranged on the top of the mounting plate at the end opposite to the first mounting frame, a tension adjustment structure arranged in the center of the top of the mounting plate, a universal adjustment structure arranged on the end of the mounting plate opposite to the first mounting frame, and a yarn guide tube arranged at the bottom of the universal adjustment structure;

[0006] The universal adjustment structure is equipped with a stabilizing structure.

[0007] This invention utilizes a designed universal adjustment structure and yarn guide tube. After being guided, the yarn enters through the second through-hole and then passes through the yarn guide tube. The yarn guide tube can be rotated and adjusted in any direction via the universal adjustment structure, allowing for precise control of its angle. This means the angle of the yarn passing through the yarn guide tube can also be precisely controlled and adjusted. Operators can adjust the yarn angle according to actual yarn feeding requirements to correct yarn deviations, ensuring accurate yarn feeding into the flat knitting machine. Furthermore, this invention incorporates a stabilizing structure within the universal adjustment structure. When the fixing screw in the universal adjustment structure... When the bolt is tightened and placed on the sphere to fix it, the stabilizing structure will rotate together with the fixing bolt. When the fixing bolt is tightened to the correct position, the triangular inclined insert in the stabilizing structure will engage with the corresponding inclined groove. At this time, the triangular inclined insert and the inclined groove can only rotate in one direction and cannot rotate in the opposite direction. This can limit the fixing bolt and prevent the fixing bolt from rotating in the opposite direction during the use of the device, which would cause the sphere to loosen. This ensures the stabilizing effect of the universal adjustment structure on the yarn guide tube, thereby further improving the stability of the yarn guide tube in adjusting and guiding the yarn.

[0008] Preferably, the tension control structure includes a second mounting bracket, an electric push rod, a pressure sensor, a fixed bracket, and a third guide wheel. The second mounting bracket is arranged on a mounting plate, the electric push rod is arranged on the second mounting bracket, the pressure sensor is arranged at the piston end of the electric push rod that extends into the second mounting bracket, the fixed bracket is arranged at the bottom of the pressure sensor, and the third guide wheel is rotatably arranged inside the fixed bracket.

[0009] Preferably, the universal adjustment structure includes an open sleeve and a ball, the ball being movably arranged inside the open sleeve, and a mounting sleeve being arranged on one side of the open sleeve corresponding to the center of the ball, with a fixing bolt screwed into the mounting sleeve.

[0010] Preferably, a connecting rod is arranged at the bottom of the sphere, the connecting rod is connected to the yarn guide tube, and an L-shaped connecting rod is arranged at the top of the open sleeve, the L-shaped connecting rod is connected to the mounting plate.

[0011] Preferably, the ends of the first through hole, the second through hole, and the yarn guide tube are all rounded.

[0012] Preferably, the stabilizing structure includes two sets of mounting rings, which are rotatably arranged on the mounting sleeve. Two sets of symmetrical mounting blocks are arranged on the two sets of mounting rings. A connecting frame is slidably arranged on the mounting block. The connecting frame is connected to the fixing bolt. A triangular inclined insert is arranged at the bottom of the mounting block by a spring. An inclined tooth groove is opened around the circumference of the mounting sleeve, and the inclined tooth groove corresponds to the triangular inclined insert.

[0013] Preferably, a U-shaped frame is inserted into the mounting block, the U-shaped frame passes through the bottom end of the mounting block and is connected to the triangular inclined insert, the spring is sleeved on the U-shaped frame, and a screw is screwed onto the center of the top of the U-shaped frame.

[0014] Preferably, the mounting block has T-slots on both sides, and the connecting frame has T-strips arranged on both sides inside, with the T-strips passing through the T-slots.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, through its designed universal adjustment structure and yarn guide tube, guides the yarn through the second through hole, and then the yarn passes through the yarn guide tube. The yarn guide tube can be rotated and adjusted in any direction via the universal adjustment structure, thereby allowing precise control of the angle of the yarn guide tube. In other words, the angle of the yarn passing through the yarn guide tube can also be precisely controlled and adjusted. Operators can adjust the yarn angle according to the actual yarn feeding requirements to correct yarn deviations, thus ensuring that the yarn is accurately fed into the flat knitting machine. This solves the technical problem that current yarn guide conveyor frames are not convenient for precise adjustment of the yarn feeding angle. Therefore, this utility model has the advantage of precise yarn guidance and adjustment.

[0017] 2. This utility model also incorporates a stabilizing structure into the universal adjustment structure. When the fixing bolt in the universal adjustment structure is tightened and presses against the sphere to fix it, the stabilizing structure rotates along with the fixing bolt. Once the fixing bolt is fully tightened, the triangular inclined insert in the stabilizing structure engages with the corresponding inclined tooth groove. At this point, the triangular inclined insert and the inclined tooth groove can only rotate in one direction and cannot rotate in the opposite direction. This limits the fixing bolt and prevents it from rotating in the opposite direction during use, which could cause the sphere to loosen. This ensures the stabilizing effect of the universal adjustment structure on the yarn guide tube, thereby further improving the stability of the yarn guide tube in guiding yarn adjustment.

[0026] like Figures 1 to 6 As shown, the present invention relates to a yarn guiding and conveying device for rib fabric, comprising a base 1, a plurality of equidistant yarn bobbin placement racks 101 arranged on the top of the base 1, a first mounting frame 2 arranged on the top of the base 1, a first through hole 201 corresponding to the yarn bobbin placement rack 101 opened on the top of the first mounting frame 2, a first yarn guide wheel 3 corresponding to the first through hole 201 arranged on the top of the first mounting frame 2, a mounting plate 4 corresponding to the first yarn guide wheel 3 arranged on one side of the top of the first mounting frame 2, a second through hole 401 opened on the top of the mounting plate 4 facing away from the first mounting frame 2, a second yarn guide wheel 5 corresponding to the second through hole 401 arranged on the top of the mounting plate 4 facing away from the first mounting frame 2, a tension adjustment structure 6 arranged in the center of the top of the mounting plate 4, a universal adjustment structure 7 arranged on the top of the mounting plate 4 facing away from the first mounting frame 2, and a yarn guide tube 8 arranged at the bottom of the universal adjustment structure 7;

[0027] In the process of knitting rib fabric, the yarn bobbin is first placed on the yarn bobbin holder 101, and then the yarn is passed through the first through hole 201, then through the first yarn guide wheel 3, the third yarn guide wheel 605 of the tension adjustment structure 6, and the second yarn guide wheel 5. Finally, the yarn is led out from the second through hole 401 and then connected to the flat knitting machine. After the flat knitting machine is working, it will pull out the yarn on the yarn bobbin, thereby achieving the guiding and conveying effect of the yarn.

[0028] To ensure the quality of rib knitting, the yarn leading out from the second through hole 401 can be passed through the yarn guide tube 8 again. Then, the angle of the yarn guide tube 8 can be adjusted in any direction through the universal adjustment structure 7. That is, the angle of the yarn passing through the yarn guide tube 8 can be adjusted and guided. Therefore, the operator can adjust the angle of the yarn according to the actual yarn feeding requirements to correct the yarn deviation, thereby ensuring that the yarn can be accurately fed into the flat knitting machine and avoiding the situation where the width of the rib fabric is inconsistent due to yarn deviation.

[0029] Specifically, the tension control structure 6 includes a second mounting bracket 601, an electric push rod 602, a pressure sensor 603, a fixed bracket 604, and a third guide wheel 605. The second mounting bracket 601 is arranged on the mounting plate 4, the electric push rod 602 is arranged on the second mounting bracket 601, the pressure sensor 603 is arranged at the piston end of the electric push rod 602 that extends into the second mounting bracket 601, the fixed bracket 604 is arranged at the bottom of the pressure sensor 603, and the third guide wheel 605 is rotatably arranged inside the fixed bracket 604.

[0030] Furthermore, the universal adjustment structure 7 includes an open circular sleeve 701 and a ball 702. The ball 702 is movably arranged inside the open circular sleeve 701. A mounting sleeve 703 is arranged on one side of the open circular sleeve 701 corresponding to the center of the ball. A fixing bolt 704 is screwed into the mounting sleeve 703. A connecting rod 706 is arranged at the bottom of the ball 702 and is connected to the yarn guide tube 8. An L-shaped connecting rod 707 is arranged at the top of the open circular sleeve 701 and is connected to the mounting plate 4. The ball 702 can be adjusted in various directions to a certain extent in the open circular sleeve 701. Then, by tightening the fixing bolt 704, it is fixed to the ball 702, thereby fixing the ball 702, that is, fixing the yarn guide tube 8.

[0031] Furthermore, the ends of the first through hole 201, the second through hole 401, and the yarn guide tube 8 are all rounded. The rounded corners can effectively protect the passing yarn and reduce yarn wear.

[0032] In an embodiment of this utility model, a stabilizing structure 9 is arranged on the universal adjustment structure 7; the stabilizing structure 9 includes two sets of mounting rings 901, which are rotatably arranged on the mounting sleeve 703. Two sets of symmetrical mounting blocks 902 are arranged on the two sets of mounting rings 901. A connecting frame 903 is slidably arranged on the mounting block 902. The connecting frame 903 is connected to the fixing bolt 704. A triangular inclined insert 905 is arranged at the bottom of the mounting block 902 through a spring 906. An inclined tooth groove 705 is opened around the mounting sleeve 703, and the inclined tooth groove 705 corresponds to the triangular inclined insert 905. A U-shaped frame 904 is inserted into the mounting block 902. The U-shaped frame 904 passes through the bottom end of the mounting block 902 and is connected to the triangular inclined insert 905. The spring 906 is sleeved on the U-shaped frame 904. A screw 907 is screwed onto the center of the top of the U-shaped frame 904.

[0033] After the yarn guide tube 8 is adjusted at an angle by the universal adjustment structure 7, the fixing bolt 704 is tightened to secure the ball 702. At this time, the stabilizing structure 9 will rotate together with the fixing bolt 704, and the mounting sleeve 703 will slide on the mounting block 902 as the fixing bolt 704 is tightened. When the fixing bolt 704 is tightened to the correct position, the triangular inclined insert 905 in the stabilizing structure 9 will engage with the corresponding inclined groove 705. At this time, the triangular inclined insert 905 and the inclined groove 705 can only rotate in one direction and cannot rotate in the opposite direction. This can limit the fixing bolt 704 and prevent the fixing bolt 704 from rotating in the opposite direction during the use of the device, which would cause the ball 702 to loosen. This ensures the stabilizing effect of the universal adjustment structure 7 on the yarn guide tube 8, thereby further improving the stability of the yarn guide tube 8 in guiding the yarn adjustment.

[0034] Specifically, T-slots 909 are provided on both sides of the mounting block 902, and T-strips 908 are arranged on both sides inside the connecting frame 903, with the T-strips 908 penetrating through the T-slots 909. With the cooperation of the T-slots 909 and the T-strips 908, the connecting frame 903 can be slidably installed on the mounting block 902.

[0035] Working principle: This embodiment provides a yarn guiding and conveying device for rib fabric. First, during the rib fabric knitting process, the yarn bobbin is placed on the yarn bobbin placement frame 101. Then, the yarn passes through the first through hole 201, followed by the first yarn guide wheel 3, the third yarn guide wheel 605 of the tension adjustment structure 6, and the second yarn guide wheel 5. Finally, the yarn is led out from the second through hole 401 and then connected to the flat knitting machine. After the flat knitting machine is working, it will pull out the yarn on the yarn bobbin, thereby achieving the guiding and conveying effect of the yarn.

[0036] Secondly, in order to ensure the quality of rib knitting, the yarn led out from the second through hole 401 can be passed through the yarn guide tube 8 again. Then, the angle of the yarn guide tube 8 can be adjusted in any direction through the universal adjustment structure 7. That is, the angle of the yarn passing through the yarn guide tube 8 can be adjusted and guided. Therefore, the operator can adjust the angle of the yarn according to the actual yarn feeding requirements to correct the yarn deviation, thereby ensuring that the yarn can be accurately fed into the flat knitting machine and avoiding the situation that the width of the rib fabric is inconsistent due to yarn deviation.

[0037] Finally, after the yarn guide tube 8 has been angled by the universal adjustment structure 7, the fixing bolt 704 is tightened to secure the ball 702. At this time, the stabilizing structure 9 will rotate together with the fixing bolt 704, and the mounting sleeve 703 will slide on the mounting block 902 as the fixing bolt 704 is tightened. When the fixing bolt 704 is tightened to the correct position, the triangular inclined insert 905 in the stabilizing structure 9 will engage with the corresponding inclined groove 705. At this time, the triangular inclined insert 905 and the inclined groove 705 can only rotate in one direction and cannot rotate in the opposite direction. This can limit the fixing bolt 704 and prevent the fixing bolt 704 from rotating in the opposite direction during the use of the device, which would cause the ball 702 to loosen. This ensures the stabilizing effect of the universal adjustment structure 7 on the yarn guide tube 8, thereby further improving the stability of the yarn guide tube 8 in guiding the yarn adjustment.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
