Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figures 1-6The utility model provides an embodiment: a device for removing the blow molding port of a plastic bottle, comprising a frame 1, a shell 3 fixedly connected to the inside of the frame 1, a mold 2 slidably connected to the inside of the shell 3, because the mold 2 slides inside the shell 3, it will not affect subsequent replacement operations, the outer wall of the mold 2 is slidably connected to a connecting block 11, a cutting component is provided inside the connecting block 11, a stabilizing component is provided inside the shell 3, the stabilizing component is used to stabilize the blow molding position of the mold 2, and a frosting component is provided inside the shell 3; the cutting component includes a threaded rod 16, the outer wall of the threaded rod 16 is threadedly connected to the connecting block 1 11, one end of the threaded rod 16 is fixedly connected to the connecting block 3 20, and the other end of the threaded rod 16 is fixedly connected to the hand wheel disc 10. By turning the hand wheel disc 10, the threaded rod 16 can be rotated inside the connecting block 11 so that it can move. The movement of the threaded rod 16 can drive the connecting block 3 20 to move. The outer wall of the connecting block 3 20 is fixedly connected to the fixed block 13, and the interior of the fixed block 13 is fixedly connected to the connecting rod 2 15. The outer wall of the connecting rod 2 15 is rotatably connected to the connecting rod 14. The outer wall of the fixed block 13 is fixedly connected to the tool 7, and the tool 7 is slidably connected to the guide rod 2 1. The movement of the connecting block 3 20 can drive the connecting rod 14 to rotate, so that the tool 7 can be moved on the guide rod 21, and the guide rod 21 guides the movement of the tool 7; the stabilizing component includes a conical nozzle 4, the outer wall of the conical nozzle 4 is fixedly connected to the inside of the shell 3, and the installation of the conical nozzle 4 creates conditions for achieving automatic cutting; the grinding component includes a grinding sheet 8, and the lower surface of the grinding sheet 8 is slidably connected to a circular guide rail 9. The grinding sheet 8 is driven to move by the circular guide rail 9, and the burrs of the blow molding port can be polished by grinding the grinding sheet 8. The surface of the grinding sheet 8 is smooth. A certain curvature can be set to prevent it from affecting the normal operation of the tool 7. The outer wall of the circular guide rail 9 is fixedly connected to the inside of the mold 2; the outer wall of the mold 2 is fixedly connected to the pull rod 6, and the mold 2 can be pulled out of the shell 3 by pulling the pull rod 6. A dustproof plate 5 is provided on the upper surface of the connecting block 11. By setting the dustproof plate 5, excess dust can be prevented from entering the cutting assembly and causing unnecessary losses; one end of the guide rod 21 is fixedly connected to the connecting block 11; the outer wall of the tool 7 is set inside the shell 3; one end of the guide rod 21 is fixedly connected to the connecting block 11; the outer wall of the tool 7 is set inside the shell 3.

[0031] Reference Figure 1 、 Figure 5 、 Figure 7 and Figure 8, the shell 3 is slidably connected to a connecting block 2 17. By setting the connecting block 2 17 inside the shell 3, conditions for subsequently tightening the screw 12 are provided. The connecting block 2 17 is threadedly connected to the screw 12, and one end of the screw 12 is fixedly connected to an extrusion block 18. By turning the screw 12, it is allowed to move inside the connecting block 2 17. The movement of the screw 12 can drive the extrusion block 18 to move together. The outer wall of the extrusion block 18 is slidably connected to a tightening sleeve 19. The movement of the extrusion block 18 allows the tightening sleeve 19 to diffuse to the surroundings, and its diffusion creates conditions for subsequent installation; the outer wall of the tightening sleeve 19 is slidably connected to the inside of the mold 2, and the tightening sleeve 19 is set inside the mold 2. When the inside of the tightening sleeve 19 is squeezed, the outer wall will diffuse to the surroundings to squeeze the mold 2 so that it is firmly fixed to the inside of the mold 2, so that the mold 2 can be installed inside the shell 3, and the outer wall of the screw 12 is set inside the shell 3

[0032] Working principle: First, the blow molding mouth of the blow-molded plastic bottle must be cut off. First, the threaded rod 16 is moved inside the connecting block 11 by rotating the hand wheel 10. The connecting block 3 20 is squeezed inward by the push of the threaded rod 16. The outer wall of the connecting block 3 20 is installed with a fixed block 13, and the fixing block 13 is installed with a connecting rod 2 15. By installing the connecting rod 14 on the outer wall of the connecting rod 2 15, the connecting rod 14 is rotated when the connecting block 3 20 moves, so that pressure is applied to the tool 7, so that the tool 7 moves on the outer wall of the guide rod 21. The blow molding mouth can be cut off by the movement of the tool 7. When the cutting work is completed, the tool 7 is first retracted to prevent it from affecting the subsequent grinding work, and the grinding sheet 8 is driven on it by the circular guide rail 9. The mold 2 is moved by the screw 12, and the burrs left by the blow molding mouth can be polished smooth by the movement of the polishing sheet 8, so as to prevent the subsequent work from being affected by the burrs. When the mold 2 needs to be replaced, the screw 12 is screwed, and the screw 12 can be moved by the connection between the outer wall of the screw 12 and the connecting block 2 17. Because an extrusion block 18 is installed at the tail end of the screw 12, when the screw 12 moves, it will also drive the extrusion block 18 to move. The inward movement of the extrusion block 18 can squeeze the expansion sleeve 19 placed inside the mold 2. The extrusion of the extrusion block 18 can make the expansion sleeve 19 squeezed all around. The extrusion of the mold 2 by the expansion sleeve 19 can realize that the extrusion block 18, the expansion sleeve 19 and the mold 2 are fixed together, thereby achieving the installation effect of the mold 2.
