[0001] The utility model relates to the technical field of rapier looms, in particular to a side support mechanism of a rapier loom. Background Art

[0002] Velvet fabric is woven using the double-layer fabric process. Double-layer fabric is composed of two or more independent warp yarns and two or more independent weft yarns interwoven into two overlapping layers of fabric. In the double-layer fabric, the upper warp yarn and the upper weft yarn are called the surface warp and the surface weft, and the surface warp and the surface weft are woven into the surface fabric. The warp yarn and the weft yarn of the lower layer are called the inner warp and the inner weft. The structure interwoven with the inner warp and the inner weft is called the inner layer structure, and the warp and weft interweaving points connecting the upper and lower fabrics are called junction points. Therefore, the characteristic of double-layer fabric compared to ordinary fabric is that the fabric layer is thicker.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 A side support mechanism of a rapier loom in this embodiment includes a fixed cross frame 1, and a side support mechanism for supporting the fabric is arranged inside the fixed cross frame 1.

[0026] The side support mechanism includes a first baffle plate 2 fixedly connected to the middle of a fixed horizontal frame 1, a connecting column 3 rotatably connected to the left and right sides of the first baffle plate 2, a threaded rod 4 slidably connected to the outside of the connecting column 3, a second baffle plate 7 plugged into one end of the threaded rod 4, a torsion spring 8 fixedly connected to the side of the second baffle plate 7 away from the threaded rod 4, a threaded block 10 threadedly connected to the outside of the threaded rod 4, a connecting plate 11 fixedly connected to the front end surface of the threaded block 10, a support rod 13 fixedly connected to the upper front end surface of the connecting plate 11, a thorn shaft 14 rotatably connected to the lower front end surface of the connecting plate 11, a limiting component arranged on the back of the threaded block 10, and a cutting and collecting structure arranged on the outside of the thorn shaft 14 for cutting and collecting fabrics.

[0027] The cutting and collecting structure includes a cutting knife 18 fixedly mounted on the outer wall of one side of the barbed shaft 14, a collecting box 19 fixedly connected to the lower side of the connecting plate 11, two material guide plates 20 fixedly connected to the inner wall of the collecting box 19, and a supporting assembly arranged on the outer side of the barbed shaft 14 for sharing support.

[0028] Among them, the limit assembly includes a limit block 22 attached to the back of the threaded block 10 and an insert block 23 inserted in the limit block 22 away from the side of the threaded block 10, the support assembly includes a rubber sleeve 15 fixedly sleeved on the left and right sides of the thorn shaft 14, a thorn ring 16 fixedly sleeved on the outside of the rubber sleeve 15, and a plurality of convex thorns 17 fixedly connected to the outside of the thorn ring 16. An observation assembly for adjusting the spacing is provided on the upper side of the fixed cross frame 1. The observation assembly includes a scale 21 fixedly connected to the upper side of the fixed cross frame 1, and a scale pointer 12 fixedly connected to the middle part of the upper side of the connecting plate 11. A turntable 9 is fixedly sleeved on the side of the torsion spring 8 away from the second baffle 7. One side of the second baffle 7 is fixedly connected to the side of the fixed cross frame 1 by bolts. A slider 6 is fixedly connected to the inner wall of the threaded rod 4. Slide grooves 5 are provided on the upper and lower sides of the connecting column 3. The slider 6 is slidably connected in the slide groove 5, and a plurality of convex thorns 17 are arranged vertically equidistantly.

[0029] It should be noted that when the threaded block 10 needs to be moved out from the outside of the threaded rod 4, the insert block 23 is pulled out from the limit block 22, and the limit block 22 is separated from the threaded block 10. After the second baffle 7 is separated from the side of the fixed cross frame 1, the threaded rod 4 is moved out and rotated to move the threaded block 10 out from the outside of the threaded rod 4, and the barbed shaft 14 and the support rod 13 on the front end face of the connecting plate 11 are replaced or repaired.

[0030] The working principle of the above embodiment is:

[0031] One end of the fabric is wound between one of the barbed shafts 14 and the support rod 13, and the other end of the fabric is placed between the other support rod 13 and the barbed shaft 14. According to the width of different fabrics, the second baffle 7 can be separated from the left and right sides of the fixed horizontal frame 1 by bolts, and the threaded rod 4 is pulled in the sliding groove 5 of the slider 6 to pull the connecting column 3 to extend the threaded rod 4 from the fixed horizontal frame 1, and then the turntable 9 is held to rotate the threaded rod 4 to drive the outer connecting plate 11 of the threaded block 10 to move on the outer surface of the threaded rod 4 to adjust the spacing. After the spacing is adjusted, the second baffle 7 is inserted into the left and right sides of the fixed horizontal frame 1, and the scale pointer 12 can be used on one side of the scale 21 to specifically adjust the spacing. The accurate scale is obtained. When the turntable 9 is rotated normally, the torsion force of the torsion spring 8 can be used to prevent the turntable 9 from driving the threaded rod 4 to rotate. When the fabric is on the surface of the thorn shaft 14, the convex thorns 17 on the outer side of the thorn ring 16 can increase the force of sharing the outward expansion, so that the fabric reaches a predetermined width, ensuring that the fabric does not tilt, and the rubber sleeve 15 can prevent the fabric from generating static electricity. When the fabric moves outside the thorn shaft 14, the protruding thread ends on the sides will be neatly cut by the cutting knife 18, and the cut thread ends will naturally fall downward into the collection box 19. The guide plate 20 in the collection box 19 can guide and isolate the thread ends to prevent the thread ends from floating out and play a blocking role.

[0032] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
