Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of textile equipment, and particularly relates to a weft insertion frame for a rapier loom. Background Art
[0002] Traditionally, multiple bobbins are arranged side by side on a creel, from which the yarn is unwound and pulled into the loom. On a rapier loom, the rapier connects the yarn and inserts the weft from one side of the loom. However, this traditional creel arrangement requires stopping the machine to replace the yarn from one bobbin when it runs out, impacting production efficiency. Furthermore, yarn tension varies between bobbins located at different positions, which can easily cause weft breakage. Utility Model Content
[0003] The purpose of the utility model is to provide a weft insertion frame for a rapier loom to solve the above technical problems.
[0004] The technical solution adopted by the utility model is a rapier loom weft insertion frame, including a base frame, the base frame is T-shaped, and is composed of a crossbeam and a longitudinal beam vertically arranged in the middle of the crossbeam, and a first column, a second column and a third column are respectively upright at both ends of the crossbeam and the outer end of the longitudinal beam, and a mounting seat is provided on the first column and the second column, one side of the mounting seat is connected to the yarn guide rod, the yarn guide rod extends to the third column, the yarn tube is sleeved on the yarn guide rod, and a yarn guide plate is provided on the third column corresponding to the yarn guide rod, a yarn guide hole is opened in the center of the yarn guide plate corresponding to the outlet of the yarn tube, and a porcelain eye is installed on the yarn guide hole.
[0005] Preferably, a yarn blocking plate is further provided between the first column, the second column and the third column, and the yarn blocking plate is located 10-15 cm below the yarn drum.
[0006] Preferably, there are at least two groups of the above-mentioned mounting seats, yarn guide plates and yarn blocking plates, which are spaced apart along the height direction of the first column, the second column and the third column. A support rod is also installed on the third column through a connecting block, and a tension wheel is installed at the end of the support rod.
[0007] Preferably, a circular hole is opened in the center of the above-mentioned mounting seat, and the mounting seat is slidably mounted on the first column or the second column through the circular hole. A threaded hole is opened on one side of the mounting seat, and the threaded hole passes through the circular hole. A screw is used to fix the mounting seat and the first column or the second column through the threaded hole.
[0008] Preferably, the ends of the transverse beam and longitudinal beam are located below the first column, the second column and the third column and are connected to universal wheels through wheel frames respectively.
[0009] Compared with the prior art, the beneficial effect of the present invention is that the yarn frame provided by the present invention has a compact structure, occupies a small space, is convenient to be set on one side of the loom for direct weft insertion, and shortens the traction distance. Among them, yarn guide rods are correspondingly arranged on the two columns to place the yarn tubes, and the line output directions of the two yarn tubes are consistent. The yarn joints of the two yarn tubes can be directly connected, and the weft insertion production does not stop the machine, thereby improving production efficiency. At the same time, the yarn is led out through the yarn guide hole, reducing the influence of the yarn tube position on the tension and reducing the yarn breakage rate. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 This is a schematic diagram of the structure of the utility model. DETAILED DESCRIPTION
[0011] The present invention will be further explained below with reference to the accompanying drawings to facilitate better understanding by those skilled in the art.
[0012] Example 1
[0013] like Figure 1 As shown, a weft insertion frame of a rapier loom includes a base frame 1, which is T-shaped and consists of a crossbeam 101 and a longitudinal beam 102 vertically arranged in the middle of the crossbeam 101. A first column 2, a second column 3 and a third column 4 are respectively upright at both ends of the crossbeam 101 and the outer end of the longitudinal beam 102. A mounting seat 5 is provided on the first column 2 and the second column 3. One side of the mounting seat 5 is connected to a yarn guide rod 6, and the yarn guide rod 6 extends to the third column 4. A yarn bobbin 7 is sleeved on the yarn guide rod 6. There are two third columns 4. A yarn guide plate 8 is provided between the two columns corresponding to the yarn guide rod 6. A yarn guide hole 9 is provided in the center of the yarn guide plate 8 corresponding to the outlet of the yarn bobbin 7, and a porcelain eye is installed on the yarn guide hole 9. Yarn guide rods 6 are correspondingly arranged on the first column 2 and the second column 3 to place the yarn tube 7, and the outlet directions of the two yarn tubes 7 are consistent. The yarn joints of the two yarn tubes 7 can be directly connected, and the weft insertion production does not stop the machine, thereby improving production efficiency. At the same time, the yarn guide plate 8 has a uniform effect on the yarn that has just been unwound, reducing fluctuations. The yarn is led out through the yarn guide hole 9, reducing the influence of the position of the yarn tube 7 on the tension, and reducing the yarn breakage rate.
[0014] In order to further reduce the influence of tension fluctuation caused by the yarn unwinding balloon, a yarn blocking plate 10 is provided between the first column 2 , the second column 3 and the third column 4 . The yarn blocking plate 10 is located 10-15 cm below the yarn tube 7 .
[0015] The above-mentioned mounting seat 5, yarn guide plate 8 and yarn stop plate 10 are provided with at least two groups, which are spaced apart along the height direction of the first column 2, the second column 3 and the third column 4. A support rod 12 is also installed on the third column 4 through a connecting block 11, and a tension wheel 13 is installed at the end of the support rod 12 to facilitate the replacement of yarn bobbins and ensure continuous production; wherein, when the tension is still unbalanced, the yarn passing through the yarn guide hole 9 is pulled through the tension wheel 13 to further improve the stability of weft insertion.
[0016] A circular hole is opened in the center of the mounting seat 5, and the mounting seat is slidably mounted on the first column 2 or the second column 3 through the circular hole. A threaded hole is opened on one side of the mounting seat 5, and the threaded hole passes through the circular hole. A screw is used to fix the mounting seat and the first column 2 or the second column 3 through the threaded hole. The position of the mounting seat 5 is adjusted according to the specifications of the yarn bobbin, and the distance between the yarn bobbin 7 and the yarn stop plate 9 is changed to ensure that the yarn stop plate plays a role.
[0017] In order to facilitate the movement of the creel, the ends of the cross beam 101 and the longitudinal beam 102 are located below the first column 2, the second column 3 and the third column 4 and are connected to the universal wheels 14 through wheel frames.
[0018] The above-described embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications and improvements made by those skilled in the art to the technical solution of the present invention without departing from the spirit and principles of the present invention shall fall within the scope of protection defined by the claims of the present invention.
