Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a wool yarn tension adjustment mechanism. Background Technology

[0002] Wool yarn is yarn made from wool as the main raw material through textile processes. Wool yarn is usually based on natural wool fibers, and some products are blended with other fibers (such as polyester, acrylic, etc.) to optimize performance. The crimped structure of wool fibers gives the yarn excellent warmth retention, moisture absorption and breathability, while maintaining a soft touch.

[0003] In the wool yarn production process, in order to ensure that the wool yarn is always under tension during the transmission process, a tension adjustment mechanism is generally set up. For example, a yarn tensioning device for textiles with publication number CN104975416A changes the yarn tension by controlling the up and down movement of the yarn tensioning bar. However, the device also has two yarn guide columns, which are installed on the left and right sides of the base respectively. The distance between the yarn guide columns and the fixed column of the yarn tensioning bar is large, resulting in a large footprint of the entire device. Utility Model Content

[0004] The present invention provides a wool yarn tension adjustment mechanism to solve the above-mentioned technical problems, and the tension adjustment mechanism occupies a relatively small area.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model for a wool yarn tension adjustment mechanism is as follows:

[0006] The system includes a mounting frame; a guide plate is provided on the mounting frame; wire holes are provided on the guide plate; fixed frames are rotatably connected to both the front and rear sides of the mounting frame; the two fixed frames are symmetrically arranged, and adjusting grooves are provided on both the left and right sides of the fixed frames; an adjusting frame is vertically slidably connected to the mounting frame; adjusting crossbars corresponding to the two fixed frames are respectively connected to the front and rear sides of the adjusting frame; the adjusting crossbars are inserted into the two adjusting grooves of the fixed frames corresponding to themselves; a vertical screw is rotatably connected to the mounting frame; a rotating head for rotating the vertical screw is connected to the lower end of the vertical screw; the vertical screw is threadedly connected to the adjusting frame; and a wire roller corresponding to the wire holes is connected above the fixed frames.

[0007] A wire ring with a smooth inner wall is installed inside the wire hole.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] See Figures 1 to 5 .

[0024] A wool yarn tension adjustment mechanism includes a mounting frame 1, a guide plate 2 on the mounting frame 1, a wire hole 3 on the guide plate 2, and a wire ring 4 with a smooth inner wall installed in the wire hole 3. Preferably, the guide plate 2 has eight horizontally equidistant wire holes 3. The mounting frame 1 is connected to the left and right ends at the bottom, and each mounting panel 21 has a mounting hole 22. The mounting panels 21 facilitate the installation of the mounting frame 1.

[0025] Mounting bracket 1 is rotatably connected to fixed brackets 5 on both the front and rear sides. Specifically, mounting bracket 1 has rotating shaft holes 11 on the left and right sides corresponding to fixed brackets 5. Rotating shafts 12 are detachably connected to the left and right sides of fixed brackets 5, and the two rotating shafts 12 are rotatably connected to the two rotating shaft holes 11, with the two rotating shaft holes 11 being coaxial. More specifically, the outer end of the rotating shaft 12 is connected to a mounting plate 13, which is connected to the fixed bracket 5 by bolts. In this invention, the fixed bracket 5 is connected to the mounting plate 13 by bolts. After the mounting plate 13 is connected, the rotating shaft 12 passes through the fixed bracket 5 and is inserted into the rotating shaft hole 11. Therefore, when it is necessary to disassemble the fixed bracket 5, first unscrew the bolts between the mounting plate 13 and the fixed bracket 5, and then remove the mounting plates 13 at both ends of the fixed bracket 5. At this time, the fixed bracket 5 can be removed from the mounting bracket 1. The fixed bracket 5 is easy to install and disassemble, and it is convenient to replace the fixed bracket 5 if it is damaged.

[0026] Two fixed frames 5 are symmetrically arranged, and adjustment grooves 6 are provided on both the left and right sides of the fixed frames 5. An adjustment frame 7 is vertically slidably connected to the mounting frame 1. Specifically, vertical grooves 41 are provided on both the left and right sides of the mounting frame 1, and the adjustment frame 7 is vertically slidably connected to the two vertical grooves 41.

[0027] The front and rear sides of the adjusting frame 7 are respectively connected to adjusting crossbars 8 corresponding to the two fixed frames 5. The adjusting crossbars 8 are inserted into the two adjusting slide grooves 6 of the fixed frames 5 corresponding to themselves. A vertical screw 9 is rotatably connected to the mounting frame 1. The lower end of the vertical screw 9 is connected to a rotating head 10 for rotating the vertical screw 9 itself. The vertical screw 9 is threadedly connected to the adjusting frame 7. A guide roller 31 corresponding to the guide hole 3 is connected above the fixed frame 5. Correspondingly, eight guide rollers 31 are also connected above the fixed frame 5.

[0028] The rotating head 10 of this invention is hexagonal, so it can be rotated with a hex wrench. When the rotating head 10 rotates, it drives the vertical screw 9 to rotate as well. Since the vertical screw 9 is threadedly connected to the adjusting frame 7, the vertical screw 9 controls the adjusting frame 7 and the adjusting crossbars 8 on both sides of the adjusting frame 7 to move vertically along the vertical slide groove 41 while rotating. The rotation of the fixed frame 5 is controlled by the cooperation of the adjusting crossbars 8 and the adjusting slide groove 6, thereby adjusting the tension of the wool yarn. The design of this invention, which rotatably connects the fixed frame 5 on both the front and rear sides of the mounting frame 1, can effectively reduce the floor space compared with the prior art.
