[0002] Compared with single fiber yarn, blended yarn has more comprehensive performance, and the fiber type and proportion can be selected according to needs to obtain blended yarn with different performance. The production process of blended yarn generally includes fiber selection, fiber pretreatment, mixing and opening, carding, drawing, roving and winding. Yarn is generally wound on a bobbin, and during the winding process, the bobbin is sleeved on the winding shaft of the yarn winding equipment. In order to facilitate the installation and removal of the bobbin, the existing winding equipment mostly uses an inflatable shaft, and the shaft diameter of the inflatable shaft can be changed by controlling the air pressure, so that the bobbin can be installed quickly.

[0003] However, the existing inflatable shaft also has some limitations, such as the structural limitation of the inflatable shaft, the easy wear of the air bag and the sealing structure inside the inflatable shaft, and the possible air leakage after long-term use, which affects the stability of the clamping force. Moreover, the working air pressure of the inflatable shaft needs to be accurately adjusted, and insufficient pressure will reduce the friction, while excessive pressure may damage the air bag or the material. In addition, the perishable parts such as air bag and sealing element need to be replaced periodically, and the long-term use cost is higher than that of ordinary mechanical shaft. SUMMARY

[0006] The utility model discloses a controller changes the interval between expansion section and telescopic end to drive the slight position movement of the plug-in pole in the slot, and finally causes the position of wedge-shaped block to change synchronously, and since expansion block is limited in the slider mounting groove, expansion block cannot move in the axial direction of expansion section, which causes the relative position of expansion block and wedge-shaped block to change, and the abutting part of the two changes, and the top surface of wedge-shaped block is inclined, and the change of abutting part causes the abutting height to change, thereby causing the height position of expansion block in slider mounting groove to change.

[0007] Further, the controller is composed of a screw segment, a first limiting part, a rotating segment and a second limiting part, the outer end of the expansion section is provided with a screw hole matched with the screw segment, the rotating segment is rotatably assembled on the telescopic end, and the first limiting part and the second limiting part are located on the inner and outer sides of the telescopic end respectively.

[0016] The technical scheme of the utility model will be further specifically explained below by examples in combination with the drawings.

[0017] In the description of the utility model, it should be understood that the orientation or position relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like is the orientation or position relationship based on the drawings shown, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as a limitation on the utility model that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0018] Example 1: see Figure 1 , Figure 4 , Figure 5 and Figure 6 A winding shaft for fiber blended yarn production, comprising a main shaft body 10, a telescopic device 20 and an expansion block 30, the main shaft body is composed of a connecting section 40 and an expansion section 50, the connecting section is used for mounting and fixing with existing winding equipment, five circumferential arrayed grooves 51 are arranged on the expansion section along the length direction thereof, four slider mounting grooves 52 are further arranged in the grooves along the length direction thereof, the expansion block can be slidably placed into the slider mounting groove, the telescopic device is composed of a telescopic end 60 and five insertion rods 70, each insertion rod is inserted with the grooves one by one, four wedge-shaped blocks 71 are further arranged on the outer side wall of the insertion rod along the length direction thereof, the number of wedge-shaped blocks is consistent with that of the expansion block, and the wedge-shaped blocks are all located at the bottom region of the expansion block, a fitting inclined surface 31 is arranged on the bottom surface of the expansion block and matched with the wedge-shaped blocks, a controller 80 for controlling the distance between the telescopic end and the expansion section is arranged between the telescopic end and the expansion section; when the distance between the telescopic end and the expansion section changes, the change of the contact position of the wedge-shaped blocks and the expansion block will cause the expansion block to move outward or inward.

[0019] Specifically, see Figure 2, the controller is composed of the screw segment 81, the first limiting part 82, the rotating segment 83 and the second limiting part 84, the outer end of the expansion segment is provided with the screw hole 53 matched with the screw segment, the rotating segment is rotatably assembled on the telescopic end, the first limiting part and the second limiting part are located at the inner and outer sides of the telescopic end respectively, and the second limiting part is provided with the internal hexagonal hole 85. The second limiting part can drive the screw segment to rotate synchronously by rotating, and the distance between the expansion segment and the telescopic end can be changed after the relative rotation of the screw segment and the screw hole.

[0020] See Figure 2 and Figure 3 , the controller changes the distance between the telescopic end and the expansion segment, so that the plug rod in the slot moves slightly, and finally the position of the wedge-shaped block also changes synchronously. Since the expansion block is limited in the sliding block mounting groove, the expansion block cannot move in the axial direction of the expansion segment, which leads to the change of the relative position of the expansion block and the wedge-shaped block, and the change of the abutting position of the two. The top surface of the wedge-shaped block is inclined, and the change of the abutting position will lead to the change of the abutting height, so that the height position of the expansion block in the sliding block mounting groove will change. The height changes of all expansion blocks are synchronous, so when the expansion blocks protrude outward synchronously, the actual outer diameter of the embodiment tends to expand, and when the expansion blocks retract inward synchronously, the actual outer diameter of the embodiment tends to shrink, so that the embodiment has the effect of facilitating the disassembly and assembly of the wire barrel. Since it is a pure mechanical mechanism, it is relatively more durable and easy to maintain.

[0021] Specifically, see Figure 1 The outer side of the expansion segment is further fixedly provided with a shaft sleeve 90, five windows 91 are formed in the shaft sleeve, the number and positions of the windows and the slots are one-to-one corresponding, the width of the window is smaller than the width of the expansion block, and the top surface of the expansion block is provided with a protruding part 32 which can protrude from the window. The expansion block located below the embodiment will slide downward under the action of gravity, in order to avoid the expansion block from being pulled out of the sliding block mounting groove, the shaft sleeve is additionally installed, and the shaft sleeve limits the position of the expansion block.

[0022] It is obvious to those skilled in the art that the utility model can be changed in many ways, and such changes are not considered to be out of the scope of the utility model. All such modifications obvious to those skilled in the art will be included in the scope of the present claims.
