[0035] The present invention will be further described below in conjunction with the accompanying drawings:

[0036] like Figure 1 — Figure 7As shown, this embodiment provides a food desiccant packaging equipment, including a packaging frame 1, a packaging bag conveying system 2, a transition hopper 3, a main hopper 4, a quantitative scanning system 5, an edge sealing device 6 and a slitting device 7. The main hopper 4 is installed on the packaging frame 1 to supply granular desiccant. The transition hopper 3 is installed on the packaging frame 1. The transition hopper 3 is located at the lower side of the main hopper 4. The packaging bag conveying system 2 is installed on the packaging frame 1. The packaging bag conveying system 2 curls the packaging bag from a flat state to a folded state. The folded area of ​​the packaging bag conveying system 2 wraps the bottom of the transition hopper 3, and then the desiccant is sent into the folded packaging bag. The edge sealing device 6 and the slitting device 7 Installed on the baling machine frame 1, the edge sealing device 6 is used to seal the folded packaging bag into a cylindrical shape, and the slitting device 7 is used to cut it into sections. The main hopper 4 is provided with a drop hole 11 corresponding to the transition hopper 3. The quantitative sweeping system 5 includes a sweeping device 51 and a floating brush 52. The floating brush 52 is used to sweep the desiccant into the drop hole 11. The sweeping device 51 is rotatably installed in the main hopper 4, and the floating brush 52 is slidably installed on the sweeping device 51. The rotating trajectory of the sweeping device 51 passes above the drop hole 11. The material in the drop hole 11 is swept by the floating brush 52. The drop hole 11 is opened after each sweep of the floating brush 52, and the floating brush 52 floats to avoid large particles.

[0037] Specifically, the packaging bag conveying system 2 includes a folding guide tube 21 and a plurality of packaging bag conveying rollers 22. The folding guide tube 21 is installed on the baling machine frame 1. The folding guide tube 21 has a folding area. The folding guide tube 21 is used to fold the unfolded packaging bag into a folded state.

[0038] Specifically, the caliber of the transition hopper 3 is larger than the caliber of the drop hole 11 , so as to prevent leakage when the material falls from the drop hole 11 into the transition hopper 3 .

[0039] Specifically, the edge sealing device 6 includes two meshing edge sealing rollers, each of which has an electrically heated edge sealing ring 61, which heat-seals the folded packaging bag into a cylindrical shape. In order to separate the cylindrical packaging bag again before cutting, a heat sealing edge 62 is installed on the edge sealing roller. The heat sealing edge 62 and the edge sealing ring 61 are connected to each other. The heat sealing edge 62 separates the packaging bag into sections by heating the packaging bag. This is a prior art and will not be described in detail here.

[0040] Specifically, the slitting device 7 includes a slitting active roller 71 and a slitting passive roller 72. The slitting active roller 71 is provided with a slitting knife, which presses the slitting passive roller 72 to cut the cylindrical packaging bag into sections.

[0041] Specifically, the sweeping device 51 includes a sweeping rod 511 and a sweeping motor 512. The sweeping motor 512 is installed at the bottom of the main hopper 4, the sweeping rod 511 is installed at the output end of the sweeping motor 512, and the floating brush 52 is slidably installed on the sweeping rod 511, so that the floating brush 52 can obtain an avoidance effect when encountering large particles to prevent the material from being broken.

[0042] Specifically, the floating brush 52 includes a plurality of sliding columns 521, each of which slides along the sweeping rod 511. A sweeping brush 5211 is provided at the bottom of each sliding column 521, and magnets 5212 that attract each other are provided between each sliding column 521, so that the sliding columns 521 that collide with large particles can be lifted up individually without affecting the overall height of the floating brush 52.

[0043] Specifically, there is a material drop control plate 12 under the material drop hole 11, and a material drop accommodating chamber 13 is formed between the material drop hole 11 and the material drop control plate 12. The floating brush 52 sweeps the material into the material drop accommodating chamber 13. When the floating brush 52 sweeps to the edge of the material drop hole 11, large particles of material are easily stuck at the edge, that is, they cannot be taken away by the floating brush 52, nor can they completely enter the material drop hole 11. This half-buried situation causes the large particles of material in the prior art to be easily squeezed and damaged. However, after adopting the sliding column 521 method, the blocked sliding column 521 can be avoided upward alone, while the remaining sliding columns 521 maintain their original height under the support of the bottom of the main hopper 4 and the action of the magnets 5212 that are mutually attracted between the sliding columns 521. After the sliding column 521 that moves upward alone breaks away from the stuck material, it will be reset under the action of the adjacent attracted magnets 5212, so that all the sliding columns 521 are at the same height again, thereby ensuring that each batch of materials that finally remain in the material drop accommodating chamber 13 is basically equal and will not be broken.

[0044] A food desiccant packaging method, using a food desiccant packaging device, comprises the following steps:

[0045] S1: The packaging bag is transported to the transition hopper 3 by the packaging bag conveying system 2;

[0046] S2: The sweeping device 51 drives the floating brush 52 to move in the main hopper 4;

[0047] S3: The material in the drop hole 11 is swept by the floating brush 52, and the floating brush 52 floats up to avoid large particles. The drop hole 11 is opened after each sweep of the floating brush 52;

[0048] S4: The edge sealing device 6 seals the edges, and the slitting device 7 cuts the packets into small packets.

[0049] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
