[0002] Traditional seed packaging methods mainly rely on manual operations, which are inefficient and difficult to ensure standardization and consistency of packaging. In addition, manual packaging also has problems such as seed damage and contamination, which seriously affect the germination rate and survival rate of seeds. Therefore, with the continuous advancement of agricultural technology, automated and intelligent seed packaging machines have emerged.

[0003] The existing seed packaging machine is mainly composed of an automatic feeding structure, an automatic bagging structure and an automatic sealing structure to realize functions such as automatic metering, automatic bagging and automatic sealing of seeds. Among them, the bagging method of the seed packaging machine is usually that the suction cup structure of the manipulator extracts an empty bag from the stacked empty bags or on the conveyor belt, and transports the empty bag to the seed feeding point, then the bag opening structure at the feeding point opens the empty bag and feeds the seeds, and finally, when the empty bag is full, the manipulator simply closes it and transports it to the sealing point for sealing. The above-mentioned bagging method is not only complex in structure and cumbersome in process, but also takes a long time and consumes high energy each time, which leads to low overall packaging efficiency and high cost of seeds.

[0042] The working principle of this embodiment:

[0043] When it is necessary to package seeds, first pour the seeds to be packaged into the hopper 22 on the top of the cabinet 1, so that the seeds are collected in the automatic feeder 21, and then the automatic feeder 21 will release a certain weight of seeds, and enter the oval tube 41 through the discharge pipe 23; before that, the servo motor 34 drives the guide wheel 33 to rotate, so that its friction drives the unwinding roller 31 to unwind the packaging film roll, and also guides the packaging film into the gap between the oval tube 41 and the two half oval arc plates 42. Since one end of the two half oval arc plates 42 is jointly hinged with the inside of the cabinet 1, and the other end is provided with a film clamping conveying mechanism 7 for clamping the two ends of the packaging film, the packaging film will be folded into an oval cylinder after entering and passing through the gap between the two; then the moving component 53 will drive the moving hot clamping plate 52 to continuously reciprocate close to and away from the fixed hot clamping plate 51, and in the process of closing, the two ends of the packaging film passing through the gap will be hot-pressed and sealed, so as to preliminarily process the packaging film into a packaging tube film;

[0044] After the packaging tube film moves to the bottom of the oval tube 41, the seeds in the oval tube 41 will naturally flow into the interior of the packaging tube film, and at the same time, the moving component 2 55 drives the two slide plates 1 54 to approach each other and clamp them together, so that a pair of movable hot clamping plates 2 56 heat-press and seal the bottom of the packaging tube film with each other, which not only prevents the seeds from falling out of the bottom opening of the packaging tube film, but also can preliminarily process the packaging tube film into a packaging bag; finally, the upper end of the packaging bag containing a certain amount of seeds will move to the middle of the slide plate 1 54, and the two slide plates 1 54 will be clamped together again, so that another pair of movable hot clamping plates 2 56 heat-press and seal the bag opening of the packaging bag, and the moving component 3 62 will also simultaneously drive the two slide plates 2 61 to approach each other, so that the cutter 63 on the slide plate 2 61 passes through the long strip hole 541 of the slide plate 1 54 and extends into the cutting groove 64 on the other slide plate 2 61, thereby cutting off the connection between the packaging bag with the packaged seeds and the packaging tube film above, thereby realizing the rapid guarantee of the seeds. Before packaging the seeds, the flip assembly 43 is used to control the two semi-elliptical arc plates 42 to flip open, so that the staff can re-pull the newly replaced or broken packaging film roll into and through the gap between the semi-elliptical arc plate 42 and the elliptical tube 41.

[0045] The above-mentioned seed packaging machine can not only automatically process the packaging film into packaging bags, but also add seeds of appropriate weight into the packaging bags during the processing. Compared with packaging machines that package seeds in traditional bagging methods, this packaging machine is not only simple and effective in structure, but also because the packaging process of each portion of seeds can be carried out continuously in sequence, the packaging speed is faster and the packaging efficiency is higher.
