[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] As described in the background technology, existing pressing devices are difficult to press some packaging boxes with special shapes. For this reason, this embodiment provides a packaging box pressing device, which uses a fixing mechanism 3 to replace the mold of the special-shaped packaging box to be pressed, so as to press the special-shaped packaging box.

[0028] See also Figure 1 and Figure 3This embodiment proposes a packaging box pressing device, including a pressing plate 1, an upper pressing mold 2 is arranged below the pressing plate 1, a fixing mechanism 3 is arranged inside the pressing plate 1, the upper pressing mold 2 and the lower pressing mold 12 are both packaging box molds of special shapes, the staff places the packaging box to be pressed in the lower pressing mold 12, and presses it with the upper pressing mold 2 to complete the pressing operation of the packaging box.

[0029] See also Figure 3 A connecting slot 4 is provided on the top surface of the upper pressing mold 2, and a group of limiting holes 5 are provided on the inner wall of the connecting slot 4. When the staff installs the upper pressing mold 2, they first align the connecting slot 4 with the connecting sleeve 304, insert the connecting sleeve 304 into the connecting slot 4, and then control the sliding clamping column 309 to slide into the limiting hole 5, so that the sliding clamping column 309 limits and fixes the limiting hole 5. At this time, the upper pressing mold 2 will be fixed on the bottom surface of the pressing plate 1.

[0030] See also Figure 1 and Figure 3 The top surface of the pressing plate 1 is fixedly connected with an electric push rod 6, which is a prior art and will not be described in detail in this application. The staff can control the device to automatically press the packaging box by setting the push and pull parameters of the electric push rod 6.

[0031] The top surface of the electric push rod 6 is fixedly connected to a fixing frame 7, and the bottom end of the fixing frame 7 is fixedly connected to a supporting base 8. The fixing frame 7 and the supporting base 8 can provide support for the pressing operation of the device and increase the stability of the device.

[0032] The support base 8 is fixedly connected to an electric slide rail 9, and the electric slide rail 9 is slidably connected to a sliding base 10. The electric slide rail 9 is an existing device and will not be described in detail in this application. The two ends of the sliding base 10 are respectively fixedly connected to the slider inside the electric slide rail 9. By setting the parameters of the electric slide rail 9, the sliding speed of the sliding base 10 can be controlled, thereby controlling the automation of the pressing operation of the device.

[0033] See also Figure 2 The top surface of the sliding base 10 is fixedly connected with a fixed clamping column 11, and a lower pressing mold 12 is arranged below the upper pressing mold 2. The bottom surface of the lower pressing mold 12 is provided with a clamping groove adapted to the fixed clamping column 11. The sliding base 10 and the fixed clamping column 11 can provide support and stability for the lower pressing mold 12, so that the lower pressing mold 12 can maintain the stability of the internal packaging box during the pressing operation.

[0034] See also Figure 4The fixing mechanism 3 includes a cavity 301 opened inside the pressing plate 1, and the inner bottom wall of the cavity 301 is fixedly connected with a hinge column 302, and the top of the hinge column 302 is hinged with a transmission lever 303. When the staff presses one end of the transmission lever 303, the other end of the transmission lever 303 will be lifted through the support of the hinge column 302, thereby providing a power source for the subsequent sliding of the sliding clamping column 309.

[0035] The bottom surface of the pressing plate 1 is fixedly connected with a connecting sleeve 304, and the interior of the connecting sleeve 304 is slidably connected with a sliding rod 305. The sliding rod 305 passes through the pressing plate 1 and is slidably connected to the pressing plate 1. The sliding rod 305 is hinged to the transmission lever 303 through a pin shaft. When one end of the transmission lever 303 hinged to the sliding rod 305 is lifted, it can drive the sliding rod 305 to slide upward inside the cavity 301 and the connecting sleeve 304.

[0036] See also Figure 4 and Figure 5 The outer surface of the sliding rod 305 is fixedly connected with a fixing ring 306. When the sliding rod 305 slides upward inside the connecting sleeve 304, it can drive the fixing ring 306 to move upward, and the fixing ring 306 drives the connecting block 307 to move upward.

[0037] The outer surface of the fixed ring 306 is fixedly connected to a group of connecting blocks 307 in a circumferential array. Through the arrangement of multiple connecting blocks 307, hinged transmission rods 308 and sliding clamping columns 309, the stability of the clamping between the sliding clamping columns 309 and the limiting clamping holes 5 can be increased, so that the connection between the upper pressing mold 2 and the pressing plate 1 remains stable.

[0038] One end of each connecting block 307 is hinged with an articulated transmission rod 308, and one end of each articulated transmission rod 308 is hinged with a sliding clamping column 309. The components in the drawings are only for style reference and are not used as specific size standards. The specific size is determined according to the actual requirements of the production template.

[0039] Each sliding clamping column 309 passes through the connecting sleeve 304 and is slidably connected to the connecting sleeve 304. When the connecting block 307 moves upward, it can drive the hinged transmission rod 308 to move upward, thereby achieving a hinged effect. The hinged transmission rod 308 will drive the sliding clamping column 309 to slide on the outer surface of the connecting sleeve 304, thereby canceling the clamping effect of the sliding clamping column 309 with the limit clamping hole 5. At this time, the upper pressing mold 2 will fall off from the bottom surface of the pressing plate 1, making it convenient for the staff to replace the upper pressing mold 2.

[0040] A return spring 310 is fixedly connected to the inner bottom wall of the cavity 301, and the return spring 310 is fixedly connected to the transmission lever 303. The return spring 310 has the function of pushing the transmission lever 303 to reset. When the transmission lever 303 is not subjected to external force, the return spring 310 will push the end of the transmission lever 303 located outside the pressing plate 1 to lift up, so that the other end of the transmission lever 303 is stable downward, so that the sliding clamping column 309 can be in a stable state of clamping with the limit clamping hole 5, thereby ensuring the stability of the device.

[0041] When the pressing operation is needed on a packaging box with a special shape, the staff first presses the transmission lever 303 downwards. Under the support of the hinged column 302, the other end of the transmission lever 303 will rise. The rising transmission lever 303 drives the sliding rod 305 to slide up inside the connecting sleeve 304 and the pressing plate 1, and the sliding rod 305 drives the fixed ring 306 to slide up. The fixed ring 306 drives the hinged transmission rod 308 to move upward, and the hinged transmission rod 308 drives the sliding clamping column 309 to slide toward the inside of the connecting sleeve 304, so that the sliding clamping column 309 cancels the limiting effect of the limiting clamping hole 5. At this time, the upper pressing mold 2 falls off the bottom surface of the pressing plate 1, and then the staff removes the lower pressing mold 12 from the fixed clamping column 11. Finally, the operation is repeated to install the pressing mold corresponding to the packaging box with a special shape to the position shown by the upper pressing mold 2 and the lower pressing mold 12, and the pressing operation on the packaging box with a special shape can be carried out.
