[0033] The present invention will be further described below in conjunction with the embodiments.

[0034] Example:

[0035] A rotary hot press packaging machine, see attached Figure 1-8 ,include:

[0036] A rotating platform 1, the rotating platform 1 includes a turntable 12, the turntable 12 is provided with a plurality of hot pressing chambers 13 distributed in a symmetrical annular array, the hot pressing chambers 13 are used to place a transparent shell, and the turntable 12 is provided with a plurality of movable parts 14 respectively located around each group of the hot pressing chambers 13, and each group of hot pressing chambers 13 is surrounded by a plurality of movable parts 14, when the movable parts 14 are squeezed, the transparent shell will be squeezed and bent toward the central area, which is used to assist the bending of the packaging shell during hot pressing.

[0037] Specifically, it also includes a base 11, the turntable 12 is rotatably arranged on the base 11, and a motor for driving the turntable 12 is provided on the base 11, which is used as a power source for the rotation of the turntable 12, and a conveyor belt is provided on the side of the base 11, which is used to output and collect the toys that have been hot-pressed and packaged. The base 11 is provided with a heating ring located on the inner circumference of the hot-pressing chamber 13, and when the transparent shell is extruded, the transparent shell is heated and molded, which is used to heat the turning part and assist hot-pressing molding.

[0038] Furthermore, the movable member 14 includes an auxiliary pressure strip 141 movably installed on the turntable 12 toward the hot pressing chamber 13 and a pushing member 142 movably installed on the turntable 12 and vertically downward. The auxiliary pressure strip 141 is provided with a guide platform with a trapezoidal cross-section on the side close to the hot pressing chamber 13, so as to retract into the turntable 12 after being compressed. A limit member is provided between the pushing member 142 and the turntable 12 to prevent the pushing member 142 from being separated from the turntable 12. A movable pin 143 is movably installed on the pushing member 142, and a spring 144 is sleeved on the pushing member 142 to resist the bottom of the movable pin 143, which is used to push the pushing member 142 down to squeeze the auxiliary pressure strip 141 into the hot pressing chamber 13 when the movable pin 143 is squeezed.

[0039] Furthermore, an elastic member is provided between the auxiliary pressure strip 141 and the turntable 12, which is used to always retract the auxiliary pressure strip 141 into the turntable 12. After the auxiliary pressure strip 141 is squeezed by the pushing member 142, it extends to the transparent shell in the hot pressing chamber 13, squeezing the edge of the transparent shell to be inclined. When the transparent shell is hot-pressed again, the edge of the transparent shell will cover the cardboard. The two pressings make the cardboard wrapped by the transparent shell, so that it is not easy to fall off. The end of the auxiliary pressure strip 141 that contacts the pushing member 142 is provided with a matching inclined surface, which is used to push the auxiliary pressure strip 141 to move into the hot pressing chamber 13 to bend the packaging shell when the pushing member 142 descends.

[0040] The press platform 2 includes a press platform body 21 that moves in the vertical direction and a press plate 23 that is elastically mounted at the bottom of the press platform body 21 for preliminary pressing. The press plate 23 is slidably arranged at the bottom of the press platform body 21 through a guide rod, and an elastic member is sleeved on the guide rod to always keep the press plate 23 away from the bottom of the press platform body 21. When the press platform body 21 descends, the press plate 23 contacts the cardboard and then squeezes the transparent shell for initial hot pressing. The press platform body 21 is provided with a cylinder 22, and the telescopic end of the cylinder 22 is connected to the press plate 23, which is used to start the cylinder 22 under certain conditions to pull the press plate 23 rises quickly to make room for secondary hot pressing and prevent the packaging shell from being pressed on the pressing plate 23. The pressing platform body 21 is provided with a switch 1 24 and a switch 25 electrically connected to the cylinder 22. The switch 1 24 is located on the inner wall of the guide rod groove on the pressing platform body 21. When the pressing plate 23 squeezes the paperboard and the transparent shell and contacts the inner wall of the hot pressing chamber 13, the switch 1 24 is touched at the same time to start the cylinder 22 to quickly lift the pressing plate 23 to a certain position and higher than the highest end of the transparent shell. As the pressing plate 23 descends, the movable pin 143 is squeezed to push the pusher 142 and the auxiliary pressure strip 141, so that the edge of the transparent shell is inclined as shown in FIG. Figure 8 As shown, as the pressing plate 23 continues to descend following the pressing platform body 21, the edge of the transparent shell is subjected to secondary hot pressing molding to wrap the cardboard to improve stability. During the secondary hot pressing, the pressing plate 23 will squeeze the auxiliary pressing strip 141, thereby squeezing the pushing member 142 to rise, triggering the switch 25, thereby closing the cylinder 22. After the hot pressing is completed and the pressing platform body 21 rises, the pressing plate 23 will be reset due to the elastic member.

[0041] Specifically, the press table body 21 is provided with a plurality of avoidance grooves 211 corresponding to the movable parts 14 to prevent the movable parts 14 and the press table body 21 from restricting each other's movement, and the switch 25 is located at the top of the inner wall of one group of avoidance grooves 211. When used for secondary hot pressing, the pusher 142 moves upward after being squeezed by the auxiliary pressure strip 141 and passes through the movable pin 143 to contact the switch 25 to close the cylinder 22, so that after the press table body 21 rises, the pressing plate 23 can return to its initial state for the initial hot pressing during the next hot pressing packaging.

[0042] The material discharging assembly 3 is also included, which is used to move the hot-pressed packed articles out of the turntable 12 and drop them onto the conveyor belt for centralized collection. The material discharging assembly 3 includes a fixed frame 31 and a push rod 36. The fixed frame 31 is slidably arranged on the base 11, and an elastic member is arranged between the fixed frame 31 and the base 11, which is used to always push the fixed frame 31 away from the turntable 12. A rotating sleeve 32 is rotatably installed on the fixed frame 31, and a suction cup 33 is arranged at the bottom of the rotating sleeve 32. The suction cup 33 is provided in multiple groups and is arranged on the rotating sleeve 32 through a connecting rod. The rotating sleeve 32 is provided with an arc groove 321 and a vertical groove 32 connected to each other. 2, the push rod 36 is slidably connected with the rotating sleeve 32, and a guide block extending into the arc groove 321 is provided on the push rod 36, and the guide block extends into the arc groove 321. When the push rod 36 descends, the guide block is driven to move in the arc groove 321, thereby driving the rotating sleeve 32 to rotate on the fixed frame 31. When the guide block moves into the vertical groove 322, that is, the suction cup 33 is located directly above the paperboard, an elastic air bag 34 connected with the suction cup 33 is provided in the rotating sleeve 32, and the top of the elastic air bag 34 is connected to the bottom of the push rod 36. When the push rod 36 continues to descend and the guide block is located in the vertical groove 322, the elastic air bag 34 is squeezed to discharge the gas.

[0043] In addition, it also includes a connecting pressure rod 26, which is arranged on the press table body 21 and connected to the top of the push rod 36. The connecting pressure rod 26 follows the movement of the press table body 21 to push the push rod 36 first. When the push rod 36 cannot move, the fixing frame 31 is pushed down as a whole, so that the suction cup 33 contacts the cardboard on the package, and then the packaged workpiece is moved out of the hot pressing chamber 13 as the press table body 21 rises.

[0044] In addition, a relief valve 35 is provided between the suction cup 33 and the elastic airbag 34, and the relief valve 35 is against the bottom of the fixing frame 31. When the connecting pressure rod 26 rises and the guide block on the push rod 36 enters the arc groove 321, the rotating sleeve 32 is driven to rotate, and the relief valve 35 is moved out of the fixing frame 31. At this time, the relief valve 35 opens to ventilate and release the pressure of the suction cup 33, and the object falls onto the conveyor belt. The relief valve 35 includes a plurality of holes respectively connected to the elastic airbag 34 and the suction cup 33. A fixed sleeve 351 and a movable plug 352 movably mounted on the fixed sleeve 351, wherein the outer peripheral surface of the movable plug 352 is provided with a plurality of groups of air relief grooves 354, and a spring 2 353 is provided between the movable plug 352 and the fixed sleeve 351. When the air relief valve 35 moves out of the bottom of the fixed frame 31, the movable plug 352 moves upward under the resetting action of the spring 2 353, and extends the air relief groove 354 out of the fixed sleeve 351, thereby ventilating and releasing pressure, thereby releasing the suction in the suction cup 33 and unloading the material.

[0045] Working principle: put the transparent shell into the hot pressing chamber 13, then put in the toy and cover it with cardboard, the turntable 12 rotates to enter the bottom of the pressing table body 21 to prepare for hot pressing, the pressing table body 21 descends with the pressing plate 23 to squeeze the cardboard and the transparent shell, and then the heating ring in the hot pressing chamber 13 heats and shapes it, when the guide rod on the pressing plate 23 contacts the switch 24, the cylinder 22 is started, and the pressing plate 23 is quickly pulled up to make room, and as the pressing table body 21 continues to descend to squeeze the movable part 14, the auxiliary pressing strip 141 is moved to push the edge of the transparent shell to the center of the hot pressing chamber 13, and then the pressing plate 23 follows the pressing table body 21 to descend again to squeeze the transparent shell, and cooperates with the heating ring on the inner wall of the hot pressing chamber 13 to perform secondary hot pressing molding to cover the cardboard. At this time, the cardboard is wrapped by the transparent shell and is not easy to fall off, and then The turntable 12 rotates again to move the packaged toys to the next station. During the hot pressing process, the connecting pressure rod 26 squeezes the push rod 36, and cooperates with the arc groove 321 and the vertical groove 322 on the rotating sleeve 32 to make the rotating sleeve 32 rotate and move the suction cup 33 to the top of the packaged toys. As the connecting pressure rod 26 continues to squeeze, the fixing frame 31 is lowered as a whole, so that the suction cup 33 contacts the cardboard on the package. When the push rod 36 descends, the elastic air bag 34 is squeezed to discharge the gas. When the suction cup 33 contacts the cardboard on the package, the internal gas is less in a negative pressure state, so that the cardboard is sucked when the suction cup 33 rises. Finally, when the rotating sleeve 32 rotates and moves out of the fixing frame 31, the air release valve 35 opens to release the pressure, and the packaged toys fall onto the conveyor belt for centralized collection.
