DETAILED DESCRIPTION
[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0020] like Figures 1 to 3 The device, shown in Figure 1, comprises a frame 1, with a first guide roller 2 and a second guide roller 3 rotatably mounted near each end of the frame 1. The first guide roller 2 and the second guide roller 3 are positioned at the same level and are used to guide the yarn. A yarn production and processing mechanism is located in front of the first guide roller 2, and a yarn winding mechanism is located behind the second guide roller 3.
[0021] like Figure 4 As shown, two pressure rollers 4 are installed on the frame 1 between the first guide roller 2 and the second guide roller 3. Both pressure rollers 4 are located at the same height and are raised and lowered by a first lifting mechanism. A top plate 5 is installed below the pressure rollers 4. This top plate 5 is raised and lowered by a second lifting mechanism and abuts against the pressure rollers 4. The compression between the top plate 5 and the pressure rollers 4 clamps the yarn, preventing it from rebounding or moving during cutting. The pressure rollers 4 are positioned lower than the first and second guide rollers 2 and 3, ensuring that the yarn is transported in a curved form.
[0022] Preferably, the first lifting mechanism includes a slider 10 and a first lifting cylinder 11. The slider 10 is slidably disposed within a chute provided on the frame 1, with one end connected to the pressure roller 4. The first lifting cylinder 11 is fixed to the frame 1, with the end of its piston rod connected to the slider 10. The first lifting cylinder 11 raises and lowers the slider 10 and the pressure roller 4, thereby adjusting the yarn tension.
[0023] The second lifting mechanism also includes a second lifting cylinder 12 fixed to the frame 1. The piston rod end of the second lifting cylinder 12 is connected to the bottom surface of the top plate 5, driving the top plate 5 up and down. The top plate 5 is located directly below the pressure roller 4, and its ends slide in sliding grooves provided in the frame 1. The sliding grooves constrain the position of the top plate 5, preventing it from shifting left or right when in contact with the pressure roller 4. There are two second lifting cylinders 12, symmetrically located along the center of the top plate 5.
[0024] like Figure 5 As shown, a cutter 6 is provided between the two pressure rollers 4 on the frame 1, and the cutter 6 is lifted and lowered by a third lifting mechanism to cut the yarn in real time. The third lifting mechanism includes a third lifting cylinder 13, which is fixedly mounted on a crossbeam 14 located on the frame 1, and the end of its piston rod is connected to the top of the cutter 6. The bottom of the cutter 6 is sharpened, and all yarns are cut at one time under the drive of the third lifting cylinder 13, so that the cutting is stable and efficient. At the same time, a top seat 15 is provided on the frame 1, and a storage groove is provided on the top seat 15. The cutter 6 can be accommodated in the storage groove when not in use to reduce the risk of damage. A through groove is provided on the top seat 15 for the third lifting cylinder 13 to pass through, so that the third lifting cylinder 13 is connected to the top of the cutter 6.
[0025] A dust hood 7 is provided below the cutter 6. The top of the dust hood 7 is open, and the bottom is connected to a dust box 9 provided below the frame 1 through an air duct 8. A fan is provided in the dust box 9 to suck impurities such as dust and debris from the dust hood 7 into the dust box 9.
[0026] Working process: When the linen yarn needs to be cut after winding, the top plate 5 is driven by the second lifting mechanism to rise to a close contact with the pressure roller 4, so as to fix the yarn on both sides of the cutter 6. Then the cutter 6 is driven by the third lifting mechanism to quickly descend to cut all the yarns. At the same time, the dust suction mechanism is started to remove impurities such as debris generated during cutting.
[0027] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
