Description

Technical Field

[0001] The utility model relates to a reed protecting device for a loom, belonging to the field of textiles. Background Art

[0002] In the textile industry, the loom reed protection device is a key component to ensure the normal operation of the loom and the quality of the weaving thread. However, in the existing loom reed protection device, there are some shortcomings in preventing the deviation of the weaving thread and the convenience of replacing the reed teeth.

[0003] First, existing reed protection devices mostly use fixed guide structures to prevent the deviation of the weaving wires. These structures are often unable to adapt to weaving wires of different thicknesses and elasticities, which causes the weaving wires to easily deviate during transmission, thereby affecting the quality of the fabric and the operating efficiency of the loom. In addition, since the weaving wires will experience multiple frictions and tension changes during transmission, these factors also aggravate the problem of weaving wire deviation. Secondly, in existing reed protection devices, the process of replacing the reed teeth is often cumbersome and time-consuming. Usually, the entire reed protection device needs to be removed from the loom before the reed teeth can be replaced, which not only increases the difficulty of operation, but also reduces the production efficiency of the loom. In addition, since precise alignment and fixation are required during the disassembly and installation process, this also increases the risk and cost of operation. Utility Model Content

[0023] See also Figure 1-3 A loom reed protection device comprises a frame 1, a first bracket 2 fixedly connected to the right side of the frame 1, and a second bracket 3. A positioning structure for preventing the weaving thread from deviating is arranged on the inner side of the first bracket 2.

[0024] like Figure 1 As shown, the positioning structure includes a shell 4 fixedly connected between the inner front side wall and the inner rear side wall of the first bracket 2, a threaded shaft 5 rotatably connected to the inner bottom wall of the shell 4, a handwheel 6 fixedly connected to the other end of the threaded shaft 5, a threaded block 7 threadedly connected to the outer side of the threaded shaft 5, a connecting shaft 8 fixedly connected to the bottom of the threaded block 7, a connecting plate 9 fixedly connected to the bottom end of the connecting shaft 8, an elastic telescopic rod 10 fixedly connected to the bottom of the connecting plate 9, a mounting frame 11 fixedly connected to the bottom end of the elastic telescopic rod 10, a first pulley 12 rotatably connected between the inner front side wall and the inner rear side wall of the mounting frame 11, and a second pulley 13 rotatably connected between the inner front side wall and the inner rear side wall of the second bracket 3.

[0025] It should be noted that the first bracket 2 is located above the second bracket 3, and the top end of the threaded shaft 5 sequentially penetrates the threaded groove of the threaded block 7 and the inner top wall of the shell 4 and extends to the inner side of the center of the handwheel 6 and is fixedly connected to the handwheel 6.

[0026] There are two connecting shafts 8 , which are respectively located on the left and right sides of the threaded shaft 5 . There is one connecting plate 9 , which is fixedly connected between the bottom ends of the two threaded shafts 5 .

[0027] There are four elastic telescopic rods 10 , and the four elastic telescopic rods 10 are respectively fixedly connected to the four corners of the bottom of the connecting plate 9 , so there is one mounting bracket 11 , and the mounting bracket 11 is fixedly connected between the bottom ends of the four elastic telescopic rods 10 .

[0028] An insertion port is provided on the upper surface of the frame 1 , and an insertion plate 14 is placed between the inner left wall and the inner right wall of the insertion port, and a plurality of reed teeth are fixedly connected to the bottom of the insertion plate 14 .

[0029] A handle 15 is fixedly connected to the upper surface of the insert plate 14 . The left and right walls of the insert plate 14 are both provided with mounting grooves, and threaded tubes 16 are fixedly connected to the inner sides of the mounting grooves. Bolts 17 are threadedly connected to the inner sides of the two threaded tubes 16 .

[0030] The left and right walls of the frame 1 are both provided with rotating holes adapted to the bolts 17 , and the left rotating hole is communicated with the left threaded barrel 16 , and the right rotating hole is communicated with the right threaded barrel 16 .

[0031] The bolt 17 on the left side extends through the left rotating hole to the inner side of the left threaded barrel 16 and is threadedly connected to the left threaded barrel 16, and the bolt 17 on the right side extends through the right rotating hole to the inner side of the right threaded barrel 16 and is threadedly connected to the right threaded barrel 16.

[0032] The working principle of the above embodiment is:

[0033] When the weaving thread tends to deviate during the operation of the loom, the operator can drive the threaded shaft 5 to rotate by turning the hand wheel 6. The rotation of the threaded shaft 5 causes the threaded block 7 to move along the axial direction of the threaded shaft 5, thereby driving the connecting shaft 8, the connecting plate 9, the elastic telescopic rod 10 and the mounting frame 11 to move in the vertical direction. The movement of the mounting frame 11 drives the first pulley 12 to move up and down, thereby adjusting the distance between the first pulley 12 and the second pulley 13. By adjusting the distance between the first pulley 12 and the second pulley 13 to adapt to different weaving threads, the weaving thread is stably clamped between the first pulley 12 and the second pulley 13 under the action of the first pulley 12 and the second pulley 13, and the friction between the weaving thread and the pulleys is reduced by the rolling of the first pulley 12 and the second pulley 13, thereby effectively preventing the deviation of the yarn and reducing the wear and tension loss of the weaving thread.

[0034] When the reed teeth are worn or damaged, the bolt 17 is turned to release the threaded connection with the threaded barrel 16. Then, the bolt 17 can be pulled out from the threaded barrel 16, the plug plate 14 and the frame 1 in turn. Then, the plug plate 14 is taken out from the frame 1 through the handle 15, and the reed teeth at the bottom of the plug plate 14 are taken out from the inner side of the frame 1. After the reed teeth are replaced, the plug plate 14 is put back into the plug-in port and the bolt 17 is tightened to complete the fixation.
