The lifting plate 122 is lifted and lowered by a lifting system. The lifting system can be an elevator. A positioning pin 124 is vertically fixed on the top of the lifting plate 122. The positioning pin 124 is located at the center of the lifting plate 122. The rotating plate 123 is rotatably connected to the positioning pin 124. A rotating assembly 125 and a connecting assembly 126 are arranged on the rotating plate 123. The rotating assembly 125 is connected to the lifting plate 122. The rotating plate 123 is rotated around the positioning pin through the rotating assembly 125. The axis of the mold 124 rotates, and the mold 121 is connected to the rotating plate 123 through the connecting component 126. During operation, the yarn passes through the mold 121 from left to right to be formed into a plate, wherein the plate is pulled to the right by the traction device 200, and the yarn is driven to be synchronously transported to the right at the same time. When it is necessary to adjust the height of the mold 121, the lifting plate 122 is driven to rise and fall by the elevator, and the lifting of the lifting plate 122 drives the rotating plate 123 to rotate synchronously, and the lifting of the rotating plate 123 drives the mold 121 to rise and fall through the connecting component 126. When it is necessary to adjust the angle of the mold 121, the rotating plate 123 is driven to rotate around the axis of the positioning pin 124 by the rotating component 125, and the rotation of the rotating plate 123 drives the mold 121 to rotate synchronously, that is, the adjustment of the angle of the mold 121 is realized;

When adjusting the angle of the rotating plate 123, first rotate one of the first screws 1254 to separate the first screw 1254 from the fixed block 1251. Then, rotate the other first screw 1254 to increase the depth of the first screw 1254 screwed into the corresponding first connecting block 1253. In this way, the first screw 1254 drives the first connecting block 1253 to rotate around the axis of the positioning pin 124.

[0044] The connecting assembly 126 also includes two second connecting blocks 1265 and two third screws 1266. The two second connecting blocks 1265 are arranged symmetrically in front and back, and the two third screws 1266 correspond to the two second connecting blocks 1265 one by one. The second connecting blocks 1265 are fixedly arranged on the mounting frame 1261. The third screws 1266 are parallel to the front and back directions. The third screws 1266 pass through the second connecting blocks 1265. The third screws 1266 are threadedly connected to the second connecting blocks 1265.

At this time, one of the third screws 1266 is rotated to make the third screw 1266 push the mold 121 to move forward and backward, while a gap exists between the other third screw 1266 and the mold 121, so that the front and rear position of the mold 121 can be finely adjusted. After the front and rear position of the mold 121 is adjusted, the third screw 1266 with a gap between the mold 121 and the mold 121 is rotated to make the third screw 1266 and the mold 121 press tightly to fix the mold 121 in the front and rear direction.

[0045] The connecting components 126 are provided with two, and the two connecting components 126 are arranged symmetrically on the left and right;

[0046] Then, according to actual use requirements, the lifting plate 122 can also be connected to the lifting end of the lifter by sliding left and right to achieve left and right adjustment of the lifting plate 122, that is, to achieve left and right adjustment of the mold 121.

Through the friction force, the upper crawler 221 and the lower crawler 222 drive the plate to move, that is, drive the yarn to move. Here, the upper crawler 221 and the lower crawler 222 are driven by the first motor 223 and the second motor 224 respectively, so that the moving speeds of the upper crawler 221 and the lower crawler 222 can be adjusted separately, so as to avoid relative sliding between the upper crawler 221 or the lower crawler 222 and the plate due to plate height deviation or installation deviation of the upper crawler 221 and the lower crawler 222 during the driving process of the upper crawler 221 and the lower crawler 222 by the same driving source, thereby improving the plate traction effect;

[0050] To summarize, the upper and lower positions of the mold 121 are adjusted by lifting and lowering the lifting plate 122, and the upper and lower positions of the mold 121 are fine-tuned by rotating the second screw 1263.
