[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 The present invention provides an embodiment of a quick-change mold core based on a paper cup machine, comprising a paper cup machine body 1, a fixed frame 2 fixedly connected to the side wall of the paper cup machine body 1, a limit slide bar provided on the top of the fixed frame 2, a rotating shaft 3 rotatably connected to the top of the paper cup machine body 1, the rotating shaft 3 being driven to rotate by the operation of a motor provided inside the paper cup machine body 1, a connecting frame 4 fixedly connected to the top of the rotating shaft 3, the rotating shaft 3 driving the connecting frame 4 to rotate, a connecting block 5 being inserted into the inside of the connecting frame 4, and a connecting groove adapted to the size of the connecting block 5 being opened inside the connecting frame 4; Furthermore, the inner wall of the connecting block 5 is elastically connected to a movable plate 6 via a return spring 8. When the movable plate 6 is pushed, it compresses the return spring 8, causing the return spring 8 to deform. During reset, the rebound of the return spring 8 drives the movable plate 6 to slide and reset. The movable plate 6 is slidably connected inside the connecting block 5. A connecting groove is provided inside the connecting block 5, allowing the movable plate 6 to slide inside the connecting block 5. A positioning mechanism 7 is provided on the side wall of the movable plate 6. A mold core body 9 is fixedly connected to the top of the connecting block 5. The rotation of the connecting block 5 drives the mold core body 9 to rotate. A movable component 10 is provided on the top of the fixed frame 2.

[0019] Reference Figures 2-4The positioning mechanism 7 includes a positioning block 71, the side wall of which is fixedly connected to the side wall of the moving plate 6. The moving plate 6 moves the positioning block 71 to slide inside the connecting block 5. The side wall of the connecting frame 4 has a positioning hole, through which the positioning block 71 passes and is inserted into the positioning hole. The positioning hole satisfies the connection between the positioning block 71 and the connecting frame 4. The inner side wall of the moving plate 6 is elastically connected to a positioning rod 73 via a positioning spring 72. The positioning rod 73 is slidably connected to the inner side wall of the moving plate 6. Pushing the positioning rod 73 compresses the positioning spring 72, causing the positioning spring 72 to deform. When resetting, the rebound of the positioning spring 72 drives the positioning rod 73 to slide and reset. The positioning rod 73 passes through and is slidably connected inside the connecting block 5. The side wall of the connecting frame 4 has an L-shaped groove, through which the positioning rod 73 is slidably connected. The L-shaped groove satisfies the stable connection between the positioning rod 73 and the connecting frame 4.

[0020] Reference Figures 3-5 The moving component 10 includes a servo motor 101, the side wall of which is fixedly connected to the side wall of the fixed frame 2. A gear 102 is fixedly connected to the output end of the servo motor 101. The servo motor 101 drives the gear 102 to rotate. A transport plate 103 is slidably connected to the top of the fixed frame 2. A limiting groove adapted to the size of the limiting slide bar is provided at the bottom of the transport plate 103. A placement groove adapted to the size of the mold core body 9 is opened inside the transport plate 103. The placement groove is used to place the mold core body 9. A moving rack 104 is fixedly connected to the side wall of the transport plate 103. The side wall of the gear 102 meshes with the side wall of the moving rack 104. The gear 102 drives the moving rack 104 to move during the rotation process, thereby causing the transport plate 103 to slide on the top of the fixed frame 2.

[0021] Working principle: When in use, the mold core body 9 is placed inside the transport plate 103. When the mold core body 9 needs to be replaced after long-term use, the positioning rod 73 is pushed and the positioning spring 72 is squeezed and then slides inside the moving plate 6. At the same time, the positioning rod 73 is pressed and the moving plate 6 is driven to squeeze the reset spring 8 and then slide inside the connecting block 5, thereby driving the positioning block 71 into the interior of the connecting block 5. Then the connecting block 5 is pulled out from the interior of the connecting frame 4 to satisfy the disassembly of the mold core body 9. Simultaneously, the operation of the servo motor 101 drives the gear 102 to rotate. The rotation of the gear 102 causes the moving rack 104 and the transport plate 103 to slide. During the sliding process of the transport plate 103, the mold core body 9 is moved to the top of the paper cup machine body 1. Then, the mold core body 9 is taken out from the inside of the transport plate 103. At the same time, the positioning rod 73 is pushed and the positioning spring 72 is squeezed. Then, the positioning rod 73 is pushed and the moving plate 6 is squeezed and the reset spring 8 is squeezed and the positioning block 71 is moved into the inside of the connecting block 5. The connecting block 5 is placed inside the connecting frame 4. At the same time, the push on the positioning rod 73 is released. The return of the reset spring 8 causes the moving plate 6 and the positioning block 71 to reset and then insert into the inside of the connecting frame 4. At the same time, the return of the positioning spring 72 causes the positioning rod 73 to slide and reset and then insert into the inside of the connecting frame 4, which improves the stable connection between the connecting block 5 and the connecting frame 4, and also improves the stability of the mold core body 9 during the installation process.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
