Description

Technical Field

[0001] The utility model relates to the technical field of coated yarn processing, in particular to a pressure wheel assembly with an adjustment function. Background Art

[0002] During processing, the covered yarn needs to be wound on a bobbin, which is plugged into a pressure wheel and rotates along with the shaft. The pressure wheel of an existing covered yarn machine generally cannot be adjusted according to the specifications of the bobbin, and a pressure wheel assembly with an adjustment function is required.

[0003] The existing patent with announcement number CN216662047U, named "A new pressure wheel for a coated yarn machine", discloses a new pressure wheel for a coated yarn machine, and relates to the technical field of pressure wheels for coated yarn machines. A new pressure wheel for a coated yarn machine comprises a mounting shaft, a winding bobbin and a coated yarn, wherein a plurality of movable plates are arranged on the outer side of the mounting shaft, a connecting block is fixed on the inner side of the mounting shaft body and the movable plate, a plurality of limit rods and a threaded rod are fixed on the mounting shaft body, and a plurality of horizontal limit rods and threaded rods form a group of plug rods, and the number of groups of plug rods is equal to the number of movable plates. The utility model is provided with three movable plates, springs, limit rods and threaded rods, and the nuts on the threaded rods of the movable plates are rotated in sequence to move the nuts outward, so that each movable plate moves outward under the elastic force of the spring until the outer diameter of the arc surface formed by the top of the three movable plates is slightly smaller than the diameter of the winding bobbin insertion hole, so that the winding bobbin can be inserted into the top of the three movable plates, so that there is no need to frequently replace the pressure wheel adapted to the winding bobbin, thereby reducing the production time and improving the work efficiency.

[0004] The above device moves outward through the movable plate under the elastic force of the spring until the outer diameter of the arc surface formed by the top of the three movable plates is slightly smaller than the diameter of the winding hole, so that the winding can be inserted into the top of the three movable plates. In this way, there is no need to frequently replace the pressure wheel adapted to the winding. However, different windings have not only different diameters but also different lengths. When used, it is impossible to adapt to windings of different lengths, and the length of the pressure wheel also needs to be changed according to the actual usage situation, which cannot meet people's usage needs well. In view of the above situation, technical innovation is carried out on the basis of the existing pressure wheel assembly. Utility Model Content
