[0028] In an embodiment of the present invention, a control box 6 is installed in the chassis 1. A workbench 2 is fixedly installed at the top of the chassis 1. A second electric rod 8 with a vertically upward output end is fixedly installed in the middle of the workbench 2. A holding seat 10 is detachably installed at the output end of the second electric rod 8, and a weighing device 9 is installed between the second electric rod 8 and the holding seat 10. A pair of guide rails 11 are installed on the upper end surface of the workbench 2. A sliding frame 12 is installed on each of the pair of guide rails 11.

[0029] During operation, different holding seats 10 can be installed at the output end of the second electric rod 8 according to different requirements. For different holding seats 10, a pair of third electric rods 14 can be driven to work. The pair of third electric rods 14 drive a pair of sliding frames 12 to move closer to or away from each other along a pair of guide rails 11, so that the distance between a pair of clamping rollers 16 adapts to the width of the holding seat 10, realizing pre-adjustment of sealing clamping. When performing sealing processing, a composite bag containing medicine can be placed in the holding seat 10. The composite bag is weighed by a weighing device 9 to obtain the packaging weight, and the composite bag is binocularly photographed by a binocular camera 19 to obtain binocular shooting data. The packaging weight and the binocular shooting data are transmitted to a control box 6. The control box 6 performs color recognition and size recognition on the binocular shooting data to determine the packaging color and packaging width of the composite bag. Then, according to the packaging color and packaging width, the internal model of the composite bag is determined. Furthermore, according to the internal model and the packaging weight, the clamping height and the sealing height are planned. After that, the second electric rod 8 is controlled to descend according to the clamping height, so that the second electric rod 8 drives the holding seat 10 to move downward. The composite bag moves downward with the holding seat 10 until the clamping area of the composite bag is located between a pair of clamping rollers 16. At this time, a pair of fourth electric rods 17 work, so that a pair of movable frames 15 move closer to each other, driving a pair of clamping rollers 16 to clamp the clamping area of the composite bag. At the same time, the first electric rod 5 is controlled to descend according to the sealing height, so that the first electric rod 5 drives the movable frame 21 to move downward until the sealing position of the composite bag is located between a pair of sealing blocks 24. At this time, a pair of fifth electric rods 23 are driven to work, so that a pair of sealing blocks 24 move closer to each other along a pair of second guide rods 22 to perform hot pressing and sealing on the sealing position of the composite bag, realizing automatic sealing processing of the composite bag placed in the holding seat 10.

[0030] It can be understood that composite bags of different internal models have different clamping heights and sealing heights; composite bags of the same internal model also have different clamping heights and sealing heights when they have different packaging weights.

[0031] Specifically, Figure 7 is a flowchart of packaging recognition and sealing control provided by an embodiment of the present invention.

[0032] In an embodiment of the present invention, the packaging recognition and sealing control specifically includes the following steps: Step S101, obtaining the packaging weight and binocular shooting data; Step S102, performing color recognition and size recognition on the binocular shooting data to determine the packaging color and packaging width of the composite bag; Step S103, determining the internal model of the composite bag according to the packaging color and the packaging width; Step S104: Plan the clamping height and the sealing height according to the internal model and the packaging weight; Step S105: Control the second electric rod 8 to descend according to the clamping height, and control the lifting transmission mechanism to descend according to the sealing height; Step S106: Control the clamping of the sealing and clamping mechanism; Step S107: Control the transmission of the sealing transmission mechanism.
