Description

Technical Field

[0001] The utility model relates to a winding shaft mechanism for quickly tightening a yarn tube, belonging to the technical field of textile machinery and equipment. Background Art

[0002] In the wire-reeling mechanism, a reel is often used. Generally speaking, Figure 1 As shown, the common winding shaft supports the main bobbin through the inner and outer cone sleeves, and the friction between the cone sleeve and the bobbin causes the bobbin and the bobbin to rotate synchronously.

[0003] However, due to the large difference between the cargo size and the inner diameter of the yarn tube, the ordinary winding shaft needs to use an additional sleeve to adapt to the winding and unwinding drums of different sizes, which increases the working steps and reduces the material clamping efficiency. However, the friction between the ordinary winding shaft and the yarn tube is too small, and it is easy to slip when the winding force is large. In addition, the operation of the ordinary winding shaft is too complicated, and the production efficiency is low.

[0004] At present, the prior art only has a machine-used yarn tube such as that shown in CN212832055U, and the inner and outer tube structures of the yarn tube can only improve the running stability to a certain extent. When the above problems occur, they still cannot be effectively solved and avoided.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a winding shaft mechanism for quickly tightening the yarn tube is provided, in order to achieve the purpose of having more practical value. Utility Model Content

[0006] In order to solve the above problems, the utility model provides a winding shaft mechanism for quickly tightening the bobbin, comprising:

[0007] A main shaft, wherein a right limit sleeve, an open sleeve, a sliding sleeve, a movable taper sleeve, a thrust bearing, a nut, an adjusting gasket, and an end bearing are sequentially installed from the right end to the left end of the main shaft;

[0008] An outer guard plate is connected between the right limit sleeve and the movable cone sleeve; a plurality of outer guard plates are evenly distributed on the outer periphery of the main shaft and form a structure capable of covering at least a portion of the main shaft;

[0009] The main shaft end cover is located outside the bearing and is installed on the left end of the main shaft through shaft end screws.

[0010] Furthermore, the right end of the main shaft has a taper, which is used to facilitate quick connection with other transmission components.

[0011] Furthermore, the main shaft surface has a plurality of rectangular grooves, and guide pins matching with the rectangular grooves are fixed on the outer guard plate, allowing the guide pins to slide in the rectangular grooves.

[0012] Furthermore, the movable cone sleeve and the sliding sleeve are fixed by a threaded pin, which serves to limit the moving range of the movable cone sleeve.

[0013] Furthermore, the thrust bearing and the retaining spring are installed in the movable cone sleeve, allowing the rotating nut to drive the movable cone sleeve to move horizontally.

[0014] Furthermore, at least a portion of the sliding sleeve is sleeved inside the movable cone sleeve.

[0015] Furthermore, the outside of the sliding sleeve cooperates with the outer guard plate through a guide sleeve, so as to ensure that multiple outer guard plates can move axially at the same time.

[0016] Furthermore, the outer guard plate has a curved surface.

[0017] Beneficial effects of the utility model:

[0018] The utility model forms a winding shaft structure capable of controlling the tightening of the outer guard plate through a conical surface by arranging a right limit sleeve, an opening sleeve, a sliding sleeve, a movable cone sleeve, a thrust bearing, a nut, an adjustment gasket, and a bearing on the main shaft, and arranging an outer guard plate between the right limit sleeve and the movable cone sleeve. The utility model controls the movement of the outer guard plate through the rotation of the nut, thereby controlling the maximum outer diameter of the outer guard plate after tightening, so that the tightening range is very wide, can be applied to a large range of changes, and is relatively simple to operate. Since the outer guard plate adopts an arc surface, the contact surface with the bobbin is increased, thereby increasing the friction. At the same time, the ingenious combination of the cone surface and the thread realizes the precise control of the yarn tension, and the overall structure is simple, the operation is simple, the adjustment range is large, the energy consumption is low, and the maintenance cost is low.
