[0025] Example

[0026] See also Figure 1-4 The utility model is a disposable plastic cup bottom sealing device, comprising a pressing bottom sealing component 1, wherein the pressing bottom sealing component 1 comprises a pillar 15, a top plate 16 fixed to the top of the pillar 15, a transmission seat 18 movably arranged at the middle position of the upper side of the top plate 16, a gear ring 17 fixed to the lower part of the peripheral side of the transmission seat 18, a gear 115 meshing with the gear ring 17, a shaft 116 fixed to the middle position of the gear 115, a sleeve rod 118 movably adapted to be installed inside the shaft 116 up and down, and a support rod 117 fixed to the middle position of the sleeve rod 118, and a cylindrical protrusion is integrally provided at the end of the support rod 117, and the cylindrical protrusion cooperates with a side slide groove 123 of the transmission seat 18.

[0027] Specifically, in the disposable plastic cup bottom sealing device proposed in the present application, the bottom sealing work is completed by setting a compression bottom sealing component 1 to press the bottom of the disposable plastic cup that is glued together (the processing technology of different types of plastic cups is different, and this cup bottom packaging method is aimed at the spliced ​​plastic cup production process, and is not suitable for one-piece injection molding process). The sleeve rod 118 is rotated and pressed downward to achieve the rotation and compression of the bottom of the plastic cup, so that the cup bottom and the cup body are fully matched, which is efficient and convenient.

[0028] Furthermore, a base 14 is fixed to the bottom of the pillar 15, a bottom plate 13 is fixed to the lower side of the base 14, a machine frame 11 is fixed to the bottom plate 13, a driving member 12 is installed inside the machine frame 11, and an output end of the driving member 12 is connected to a transmission seat 18 via a shaft, and the shaft is sleeved inside the pillar 15.

[0029] Specifically, the machine frame 11 is the overall bottom support structure of the compression bottom sealing assembly 1. The support system composed of the machine frame 11 and the bottom plate 13 is used for the installation and fixation of the driving member 12 and the base 14. The base 14 is used for the fixed installation of the pillar 15. After the driving member 12 is started, its output shaft drives the rotation of the transmission seat 18 through the shaft rod, so that the ring gear 17 fixed to the transmission seat 18 rotates accordingly.

[0030] Furthermore, a bracket 19 is fixed to the upper side end of the top plate 16, a guide rod 113 is passed through the top of the bracket 19, the bottom of the guide rod 113 is connected to the upper end of the sleeve rod 118, a limiting block 112 is fixed to the upper end of the guide rod 113, and a guide block 111 is symmetrically fixed on the circumference of the sleeve rod 118, and the guide block 111 cooperates with a movable groove opened on the side of the bracket 19.

[0031] Specifically, the movable groove opened on the side of the bracket 19 is used for the movable limit of the guide block 111. Under the action of the guide block 111, the sleeve rod 118 maintains stable lifting and lowering, and there is an obstruction between the limit block 112 fixed on the upper end of the guide rod 113 and the bracket 19, so that the guide rod 113 cannot be separated from the bracket 19.

[0032] Furthermore, a limiting kit 114 is fixed to the lower side of the edge of the top plate 16, a buffer kit 110 is fixed to the bottom of the limiting kit 114, the sleeve rod 118 is passed through the limiting kit 114 and the buffer kit 110, a mounting plate 119 is fixed to the bottom of the sleeve rod 118, and the ear seat around the mounting plate 119 is movably connected with a support 121, and a pressure plate 120 is fixed to the lower side of the support 121, and a buffer wheel 122 is fixed to the upper end of the support 121, and the buffer wheel 122 cooperates with the side of the buffer kit 110.

[0033] Specifically, when the sleeve rod 118 is descending, the mounting plate 119 fixed at the bottom drives the support 121 to descend. When the pressure plate 120 contacts the bottom of the cup, the reaction force causes the sleeve rod 118 to tend to move upward. At this time, the buffer wheel 122 contacts the buffer kit 110. The force exerted by the buffer kit 110 on the buffer wheel 122 will press down the bottom of the cup again to achieve a stable seal on the bottom of the cup.
