Description

Technical Field

[0001] The utility model relates to the field of siro spinning, in particular to a siro spinning anti-overlapping device. Background Art

[0002] The Siro spinning process is a spinning method that improves the traditional spinning frame and directly spins a yarn structure similar to a double-stranded yarn. Two coarse yarns are fed into the same spindle at a certain interval. The two coarse yarns are stretched separately. After the yarn strips are output from the front roller, the two yarn strips are twisted together due to the twisting effect and spun into a fine yarn. Practice has proved that the Siro spinning yarn also forms less twist from the output of the front roller to before the twisting. The two yarn strips that already have weak twist are twisted together with each other as the center to form a unique Siro yarn. The existing Siro spinning anti-overlapping device, such as a compact Siro spinning anti-overlapping device with publication number CN214400858U, comprises a frame, a traction rubber roller one, a front roller, a traction rubber roller two and a leading roller. The traction rubber roller one and the front roller are installed at the rear end of the frame, the traction rubber roller two and the leading roller are installed at the front end of the frame, and the traction rubber roller one and the traction rubber roller two are installed at the front end of the frame. The frame between the two is provided with an anti-overlapping mechanism, the anti-overlapping mechanism includes a base, a mounting block, a separation block and a suction plate. The base is fixedly mounted on one side of the frame close to the second traction rubber roller, the mounting block is fixedly mounted on the base, the separation block is mounted on the mounting block, and two suction plates are provided. The two suction plates are symmetrically arranged on both sides of the rear end of the separation block. The two suction plates are hollow and connected to the vacuum pump through a suction pipe. A number of suction holes are provided on the opposite surfaces of the two suction plates, and a trapezoidal slider is connected to the bottom of each of the two suction plates. The two trapezoidal sliders are installed in a slide groove on the base, and the slide groove runs through both sides of the base. A double-headed screw is installed between the two trapezoidal sliders, and threads with opposite rotation directions are provided at both ends of the double-headed screw. A bearing and an end cover are provided at one end of the slide groove, and the head of one end of the double-headed screw is a cylindrical structure, the diameter of the cylindrical structure is smaller than the diameter of the double-headed screw, and the cylindrical structure cooperates with the bearing.

[0003] The above-mentioned device is made of flexible materials, preferably rubber materials, through the mounting block and the deformation block, so that fine-tuning can be performed through deformation according to the tension of the yarn. However, this adjustment method is not effective. When the yarn is relatively loose, the adjustment effect of the above-mentioned adjustment method is limited. For this reason, we propose a siro spinning anti-overlap device. Utility Model Content
