By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0017] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0018] Reference Figure 1 As shown, this embodiment provides a mounting structure (hereinafter referred to as the mounting structure) that facilitates quick disassembly and assembly of a winding shaft, which is used for assembling the winding shaft of a thermal plate-paper laminating machine or a winding machine.

[0019] The mounting structure of this embodiment includes a frame 13, two chucks 6 respectively used to connect the two ends of the winding shaft 5, and a handle plate 1 rotatably assembled on the corresponding chucks 6. The two ends of the winding shaft 5 respectively have square heads 51 for connecting the chucks 6. The two chucks 6 are respectively assembled on the frame 13 through corresponding bearings 7 to ensure that the chucks 6 can rotate. Specifically, the bearings 7 are fixed to the frame 13 by screws.

[0020] A square groove 61 for accommodating the square head 51 is provided on one side of the two clamping heads 6 facing the winding shaft 5 , and a notch 62 for the square head 51 to pass through is provided on the upper side wall of the square groove 61 facing upward.

[0021] When the handle plate 1 rotates, the handle plate 1 can switch between the positions of covering and opening the gap 62, and a reinforcing screw 2 is provided between the handle plate 1 and the winding shaft 5. The reinforcing screw 2 passes through the handle plate 1 and the gap 62 in turn, and is fastened to the square head 51 located in the square groove 61, so as to facilitate quick disassembly and installation of the square head 51. The reinforcing screw 2 can also be used to better fix the winding shaft 5, thereby avoiding vibration and noise caused by mechanical clearance during the rotation of the winding shaft 5.

[0022] The mounting structure of this embodiment also includes a driving component, and the specific driving component includes a driver and a driving gear 9. The specific driver is a servo motor. The driving shaft of the driver is connected to the driving gear 9 through a belt or a gear set to drive the driving gear 9 to rotate, and then the driving gear 9 is fixedly connected to the chuck 6 on the right side through the connecting shaft 4, so that the chuck 6 on the right side serves as the active end, and the chuck 6 on the left side serves as the driven end, thereby driving the two chucks 6 and a winding shaft 5 to rotate concentrically together.

[0023] During specific implementation, one end of the connecting shaft 4 passes through the bearing 7 on the right side and is fixedly connected to the groove wall of the square groove 61 by welding and screws. The other end of the connecting shaft 4 is fixedly connected to the center of the driving gear 9 to connect the chuck 6, the connecting shaft 4 and the driving gear 9 into one.

[0024] More specifically, the handle plate 1 has a hollow inner cavity, the chuck 6 is inserted into the inner cavity of the handle plate 1 , and the inner cavity wall of the handle plate 1 facing the notch 62 is flat to ensure that the square head 51 placed in the square groove 61 is abutted and restricted by the inner cavity wall of the handle plate 1 .

[0025] A rotating pin 3 is provided between the side wall of the square groove 61 away from the notch 62 and the handle plate 1 , so that the handle plate 1 can rotate around the rotating pin 3 to cooperate with covering or opening the notch 62 of the square groove 61 .

[0026] By rotating the handle plate 1, the handle plate 1 can be switched between the positions of covering and opening the gap 62 of the square groove 61, and when the gap 62 is opened, the square head 51 of the winding shaft 5 can be taken out from the gap 62; after the square head 51 is placed into the square groove 61 from the gap 62, the handle plate 1 is rotated again to cover the gap 62, and the reinforcing screw 2 is used to tighten the square head 51, thereby realizing quick disassembly and assembly of the winding shaft 5. In this way, not only the disassembly and assembly operation of the winding shaft 5 is simple and fast, but also high production efficiency is guaranteed and the winding shaft 5 is not easy to wear.

[0027] In addition, the installation structure of this embodiment has the advantages of accurate center positioning, neat winding, the winding shaft 5 is not easy to jump and low noise, and the drive gear 9 is not directly installed on the winding shaft 5, thereby reducing the load.

[0028] Further preferably, corresponding bearing covers are respectively provided on the outward sides of the two bearings 7 to play a protective role.

[0029] Further preferably, each upward side wall of the square groove 61 is provided with a limiting protrusion 63 for limiting the rotation range of the corresponding handle plate 1, so as to ensure that the handle plate 1 is not easily separated from the corresponding clamping head 6.

[0030] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
