[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Please see Figure 1-5 As shown, this utility model is a packaging mechanism for a Chinese herbal medicine packaging machine, including a machine body 11, a material barrel 12 on its top, and a packaging part 13 in front;

[0032] The packaging section 13 has a horizontal seal 131 and a vertical seal 132 inside. An arc-shaped frame 133 is fixed between the front and rear frames of the packaging section 13 to constrain the packaging bag into an arc shape for transport. The arc-shaped frame 133 covers the filling area. The packaging bag is transported outside the arc-shaped frame 133 to prevent powdery materials from adsorbing onto the inside of the bag opening. Double-layered pressure rollers 134 are rotatably installed between the front and rear frames of the packaging section 13, located outside the arc-shaped frame 133, to squeeze the packaging bag to shape it and ensure stable heat sealing operation on both sides.

[0033] The bottom of the material hopper 12 is provided with a main pipe 14 and a secondary pipe 141. The inside of the material hopper 12 is a coaxial rotating inner cylinder 121, which is driven to rotate by a rotary motor installed at the bottom of the material hopper 12. A main discharge pipe 1211 extends downward from one side of the inner cylinder 121 for discharging material in a small amount. A secondary discharge pipe 1212 extends downward from the other side of the inner cylinder 121 for discharging material in a small amount. The main discharge pipe 1211 and the secondary discharge pipe 1212 are respectively connected to the main metering pipe 1221 and the secondary metering pipe 1222 at the bottom of the material hopper 12.

[0034] Furthermore, the upper end of the secondary pipe 141 is connected to the secondary metering pipe 1222. A small amount of material flows into the main pipe 14 through the secondary pipe 141 and is finally filled into the packaging bag. A partition 122 is fixed near the bottom of the material barrel 12, forming an annular cavity between it and the bottom plate. The upper ends of the main metering pipe 1221 and the secondary metering pipe 1222 are both fixedly connected to the partition 122.

[0035] Furthermore, a rotating frame 1223 is installed at the bottom of the material hopper 12, and multiple trays 12231 are distributed circumferentially on the outer side of the rotating frame 1223 to receive a small amount of discharged material, located between the lower opening of the secondary pipe 141 and the secondary metering pipe 1222.

[0036] Among them, the lower end of the tray 12231 is rotatably equipped with a flip-top one-way valve 12232 with a built-in weight sensing chip. When the sensing material meets the weight requirements, it will open directly to make it fall. When it does not meet the requirements, it will switch to another tray 12231 for use.

[0037] Furthermore, a flip-type check valve 12211 with a built-in weight sensing chip is rotatably installed near the bottom of the main metering tube 1221 to intercept material and determine the remaining amount after sensing its weight.

[0038] Furthermore, a side groove 12121 is provided on one side of the auxiliary discharge pipe 1212, covering a semi-circular area on one side, and a sealing plate 12131 is slidably installed inside to seal the auxiliary discharge pipe 1212.

[0039] Furthermore, an electric telescopic device 1213 is installed at the bottom of the inner cylinder 121, the movable end of which is connected to the sealing plate 12131 to control the gap between one side of the sealing plate 12131 and one side of the auxiliary discharge pipe 1212, thereby controlling the amount of material discharged.

[0040] It is understood that this utility model uses a dual-zone, different quantitative collaborative filling method to control the filling volume in two ways, thereby accurately controlling the product quality and avoiding situations where there is too much or too little filling. At the same time, the material is pre-isolated from the packaging bag during filling to prevent the bag opening from absorbing material and affecting the quality of the sealing operation.

[0041] A specific application of the operation flow of this embodiment is as follows: In use, the material first enters the main metering pipe 1221 through the main discharge pipe 1211 for a small amount of metering. After the weight sensing unit in the flip-top one-way valve 12211 senses its weight, the auxiliary discharge pipe 1212 performs secondary metering according to the amount of the remaining material. This metering is done by only a single piece of material passing through, and the opening size is controlled by the sealing plate 12131 to limit the amount of material passing through. The single piece of material passing through is received by the tray 12231. After the flip-top one-way valve 12232 senses the weight, if it matches, the bottom flip-top one-way valve 12232 opens, and the material enters the auxiliary pipe 141 and flows into the main pipe 14 for filling. If the weight does not match, the material enters the auxiliary pipe 141 and flows into the main pipe 14 for filling. The required quantity is rotated to one side by pallet 12231 and received by another pallet 12231. Unused pallets 12231 will be pre-entered into main pipe 14 during the next filling operation, and the remaining capacity of main metering pipe 1221 will be increased accordingly. The material to be filled into the packaging bag first gathers inside the arc frame 133, is dragged downwards, and then heat-seales the bottom of the next bag to be filled to form a cycle. During this period, the longitudinal seal 132 heat-seals the side of the bag in real time, and the bag is limited by the pressure roller 134 and the arc frame 133 to transport it along a predetermined path, so as to avoid the material directly contacting the bag during filling, which would cause residue on the inner side of the upper end of the bag and affect the heat sealing operation.
