The key connection has a simple structure and a strong bearing capacity, but is not easy to disassemble. As a result, the staff has to spend a lot of time when disassembling the pulley, which reduces production efficiency.

[0004] Therefore, there is an urgent need for a quick-detachable foil winding mechanism to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of the utility model is to provide a quick-detachable foil winding mechanism to solve the problem that the pulley connected to the foil winding roller is difficult to disassemble.

[0032] In the first embodiment of the present invention:

[0033] like Figure 1-5 As shown, the utility model provides a quick-detachable foil winding mechanism, which comprises: a pulley assembly 1, comprising a pulley and a tapered sleeve 11, one end of the tapered sleeve 11 is provided with a flange 103, and the flange 103 is provided with a plurality of through holes in the circumferential direction; a hub 12 is provided extending from the axis of the pulley to both ends of the pulley, and one end of the hub 12 is provided with a plurality of locking screw holes 121 matching the through holes in the circumferential direction; the axis of the hub 12 is provided with a plurality of locking screw holes 121 matching the through holes in the circumferential direction; The conical sleeve 11 is provided with a conical hole matching the conical sleeve 11, the conical sleeve 11 is arranged in the conical hole, and the flange 103 is fixed with the hub 12 by threaded connection; the winding roller 2 has a connecting shaft 21 at one end, and one end of the connecting shaft 21 is sleeved in the shaft hole of the conical sleeve 11; the winding roller 2 is used for winding up the slit foil; wherein, the conical sleeve 11 is provided with a through opening in the radial direction, and when the conical sleeve 11 and the hub 12 are locked by a screw, the connecting shaft 21 is locked in the conical sleeve 11.

[0034] The utility model provides a quick-detachable foil winding mechanism, which locks the winding roller 2 through a pulley group 1 to realize that the pulley drives the winding roller 2 to rotate; first, the pulley is passed through a connecting shaft 21 connected to one end of the winding roller 2, and then a conical sleeve 11 is passed through one end of its connecting shaft 21 and is sleeved in the conical hole of the hub 12, and finally a plurality of hexagonal screws are passed through the through holes on the flange 103 and the locking screw holes 121 on the hub 12 to lock and fix the conical sleeve 11, the pulley and the connecting shaft 21; when the winding roller 2 needs to be disassembled, it is only necessary to remove the hexagonal screws and tighten the disassembly screw holes 102 clockwise with two high-strength screws. The entire pulley assembly 1 can be removed by pushing out the tapered sleeve 11; under the above structure, the quick-detachable foil winding mechanism can quickly install and disassemble its pulley and winding roller 2, reducing the installation and disassembly time of the winding roller 2, thereby improving production efficiency; secondly, the limit block 104 is provided on the tapered sleeve 11 and the limit groove 105 is provided on the tapered hole to prevent the rotation between the tapered sleeve 11 and the pulley. At the same time, the number of hexagonal screws provided is reduced, and the time for installing and disassembling the hexagonal screws is shortened, making it easier and faster to install and disassemble the pulley assembly 1, further improving the production efficiency of the foil slitting and winding machine.

[0035] Specifically, Figure 1 and Figure 2 As shown, there are six through holes on the flange 103, and the six through holes are opened circumferentially along the edge of the flange 103, and the spacing between each through hole is the same; six locking screw holes 121 on the hub 12 are also provided corresponding to the through holes, and the connection between the tapered sleeve 11 and the pulley is that six hexagonal screws penetrate the six through holes on the flange 103 and the six locking screw holes 121 on the hub 12 for threaded locking, so that the tapered sleeve 11 is fixedly sleeved in the tapered hole at the center of the hub 12; the six hexagonal screws arranged at the same spacing make the force between the flange 103 and the hub 12 more uniform when locking, thereby ensuring that the tapered sleeve 11 can be flatly sleeved in the tapered hole, and at the same time, the setting of the six screws can ensure that when the pulley drives the winding roller 2, there will be no rotation between the tapered sleeve 11 and the pulley due to excessive torque.

[0036] Further, such as Figure 1As shown, the flange 103 and the tapered sleeve 11 are integrally formed structures, the wheel hub 12 and the wheel plate 14, the wheel rim 13, and the gear teeth on the pulley are all integrally formed structures, and the pulley is made of high-strength steel, such as carbon steel or alloy steel; two disassembly screw holes 102 are also provided on the flange 103, and the two disassembly screw holes 102 are relatively spaced apart on the flange 103. When it is necessary to disassemble the pulley assembly 1 from the connecting shaft 21, the hexagonal screw is removed, and then two high A high-strength disassembly screw is passed through the two locking screw holes 121 and tightened clockwise. When the end of the disassembly screw away from the nut hits the hub 12, continue to tighten the disassembly screw. At this time, the tapered sleeve 11 will be pushed out of the tapered hole. The tapered sleeve 11 can be removed by hand to remove the pulley from the connecting shaft 21. It should be noted that there is no opening at the position of the disassembly screw hole 102 relative to the hub 12. At the same time, the length of the disassembly screw must be greater than the length of the disassembly screw hole 102.

[0037] In this embodiment, if Figure 1 and Figure 2 As shown, a through opening is provided in the radial direction of the tapered sleeve 11, the axial hole at the axial center position of the tapered sleeve 11 is circular, and the diameter of the circular axial hole is larger than the diameter of the connecting shaft 21, the tapered hole at the axial center position of the hub 12 is matched with the tapered sleeve 11, the tapered sleeve 11 passes through the connecting shaft 21 and is then sleeved in the tapered hole, and in the process of locking it by the hexagonal screw, the tapered sleeve 11 slowly moves forward in the tapered hole, and at the same time, the opening on the tapered sleeve 11 gradually shrinks, at this time, the connecting shaft 21 will be fastened and locked in its axial hole by the tapered sleeve 11, and the installation of the pulley group 1 and the winding roller 2 can be quickly completed.

[0038] Furthermore, in order to prevent excessive torque between the pulley and the winding roller 2 from causing looseness and self-rotation between the two, key grooves 101 are respectively opened in the radial direction of the inner wall of the shaft hole of the tapered sleeve 11 and in the radial direction of one end of the connecting shaft 21. A flat key pin is provided in the key groove 101, and one end of the connecting shaft 21 is limited by the flat key pin and the tapered sleeve 11.

[0039] In this embodiment, if Figure 3As shown, the hub 12 of the pulley is arranged on the central axis position of the pulley, and extends on both sides in the width direction of the wheel plate 14 of the pulley, and the widths extended on both sides are the same. The length of the tapered hole made by the central axis of the hub 12 is the same as the length of the tapered sleeve 11. This structure can increase the contact area between the tapered sleeve 11 and the tapered hole and between the tapered sleeve 11 and the connecting shaft 21, thereby increasing the locking force; the rim 13 of the pulley extends on both sides in the width direction of the wheel plate 14 of the pulley, and the rims 13 extending on both sides have the same width, and the two end faces of the rim 13 are flush with the two end faces of the hub 12. This structure reduces the amount of material used in the manufacture of the pulley and strengthens its structural properties; therefore, the width of the gear teeth on the rim 13 is widened to facilitate adaptation to a wider belt, thereby preventing the belt from being too narrow and the belt from being damaged and stretched due to excessive torque, thereby improving the winding efficiency of the winding roller 2.

[0040] In the second embodiment of the present invention:

[0041] like Figure 4 and Figure 5 The structure of the second embodiment which is the same as that of the first embodiment is not repeated here, and the difference is that: a plurality of limit blocks 104 are provided at radial positions on the outer wall of the conical sleeve 11, preferably four limit blocks 104; and the four limit blocks 104 are provided at equal intervals on the outer wall of the conical sleeve 11, and the limit blocks 104 and the conical sleeve 11 are integrally formed; a plurality of limit grooves 105 matching the limit blocks 104 are provided radially on the inner wall of the conical hole, preferably four limit grooves 105; when the conical sleeve 11 is sleeved in the conical hole, the four limit blocks 104 correspond to It is inserted into the four limiting grooves 105 to prevent the self-rotation between the tapered sleeve 11 and the pulley; at this time, a lot of hexagonal screws are not needed to lock and fix it; therefore, only one or two through holes for the hexagonal screws to pass through are required on the flange 103 to lock and fix the tapered sleeve 11 and the pulley; in this embodiment, it is preferred to set two through holes on the flange 103, and correspondingly set two locking screw holes 121 on the wheel hub 12, and the two through holes and the two locking screw holes 121 are arranged relatively to each other to ensure that the force during locking is more uniform and linear.

[0042] Under the above structure, compared with Example 1, Example 2 reduces the number of locking screws while ensuring the strength between the pulley group and the connecting shaft by setting multiple limit blocks 104 and multiple limit grooves 105, making the installation and disassembly of the pulley group 1 easier and faster, thereby further improving the efficiency of the slitting and winding process of the foil slitting machine.

[0043] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the utility model, which does not depart from the content of the technical solution of the utility model, belongs to the scope of the technical solution of the utility model.
