[0029] Figures 1 to 6 An embodiment of a continuous powder filling system of the present invention is shown. The continuous powder filling system of this embodiment includes a filling device 1 and a filling hopper 2. The filling hopper 2 is located below the filling device 1. The filling device 1 is provided with a discharge nozzle 11, and also includes a bottle conveying mechanism 3 and a movable driving mechanism 4. The bottle conveying mechanism 3 is used to convey the bottle body 6. The movable driving mechanism 4 is used to drive the filling hopper 2 to reciprocate along the conveying direction of the bottle body 6. The length L of the inlet of the filling hopper 2 in the conveying direction of the bottle body 6 is greater than the sum of the conveying distance A required for the bottle body 6 to reach a preset filling amount plus the length B of the discharge nozzle 11 in the conveying direction of the bottle body 6. The conveying distance is the product of the single-bottle filling time of the filling device 1 and the conveying speed of the bottle conveying mechanism 3.

[0030] The packaging process of the continuous powder packaging system is as follows: the bottle conveying mechanism 3 conveys the bottle body 6, firstly Figure 3As shown, the filling hopper 2 is at the initial position. When the bottle 6 is transported to the position just below the discharge port of the filling hopper 2, the filling device 1 starts to discharge the bottle into the filling hopper 2 through the discharge nozzle 11, and then Figure 4 As shown, the mobile driving mechanism 4 drives the sub-filling hopper 2 to move along with the conveying of the bottle 6 until the bottle 6 is fully filled. Figure 5 As shown, the bottle body 6 continues to be transported forward, and the mobile driving mechanism 4 drives the sub-packaging hopper 2 to move in the reverse direction and start to reset. Figure 6 As shown, after the reset is completed, it returns to the initial position, waiting for the next batch of bottles 6 to be transported to the bottom, and the above-mentioned packaging steps are repeated.

[0031] In the continuous powder filling system, the inlet of the filling hopper 2 is always located below the feeding nozzle 11, so that the material can be continuously received, and the bottle conveying mechanism 3 continuously conveys the bottle body 6. At the same time, the mobile driving mechanism 4 drives the filling hopper 2 to always follow the bottle body 6 during the filling process to realize tracking feeding. After the previous batch of bottles 6 are filled, the next batch of bottles 6 are input, and the filling can be started after the filling hopper 2 is reset, without stopping and waiting, the filling efficiency is high, and the filling capacity is improved.

[0032] Furthermore, if Figure 2 As shown, in this embodiment, the filling hopper 2 includes a material guide portion 21 and a material discharge portion 22 disposed at the bottom of the material guide portion 21, the material discharge portion 22 is connected to the bottom of the material guide portion 21, the inlet end of the material guide portion 21 is in a long strip shape arranged along the conveying direction of the bottle body 6, and the outlet end is circular. The inlet end of the material guide portion 21 is in a long strip shape, which can reduce the diffusion and exposure of the powder to a certain extent compared with the circular shape, can protect the powder to be filled, and improve the filling accuracy.

[0033] Furthermore, if Figure 2 As shown, in this embodiment, L is the maximum diameter of the long strip inlet. The maximum diameter of the long strip inlet is greater than the sum of the conveying distance A required for the bottle body 6 to reach the preset filling amount plus the length B of the feed nozzle 11 in the conveying direction of the bottle body 6 to complete the filling, shorten the length of the filling hopper 2 in the conveying direction, and make the structure more compact.

[0034] Furthermore, if Figure 2 As shown, in this embodiment, the material discharge portion 22 is cylindrical, and the diameter of the material discharge portion 22 is equal to the diameter of the outlet end of the material guide portion 21, and is smaller than the diameter of the bottle mouth of the bottle body 6. This facilitates the docking and positioning of the material discharge portion 22 and the bottle mouth of the bottle body 6, ensuring that the powder in the material discharge portion 22 can be fully discharged into the bottle body 6 through the bottle mouth, and preventing the powder from spilling outside the bottle mouth and affecting the packaging accuracy.

[0035] Furthermore, in this embodiment, the feed nozzle 11 extends into the filling hopper 2, thereby further reducing the diffusion and exposure of the powder, protecting the filled powder, and improving the filling accuracy.

[0036] Furthermore, if Figure 1 As shown, in this embodiment, the mobile driving mechanism 4 includes a support frame 41, a screw rod 42, a sliding seat 43 and a rotary drive for driving the screw rod 42 to rotate. The screw rod 42 is rotatably arranged on the support frame 41, the sliding seat 43 is slidably arranged on the support frame 41 and is threadedly connected with the screw rod 42, and the sub-packaging hopper 2 is connected with the sliding seat 43. The rotary drive (not shown in the figure) drives the screw rod 42 to rotate, drives the sliding seat 43 to move on the support frame 41, and thus drives the sub-packaging hopper 2 to reciprocate, and the structure is simple.

[0037] Furthermore, if Figure 1 As shown, in this embodiment, the continuous powder filling system also includes a lifting drive mechanism 5 for driving the filling hopper 2 to rise and fall. The lifting drive mechanism 5 includes a lifting seat 51, a lifting guide rod 52 and a lifting drive for driving the lifting seat 51 to rise and fall on the lifting guide rod 52. The lifting guide rod 52 is arranged at both ends of the sliding seat 43, and the filling hopper 2 is connected to the lifting seat 51. The lifting drive (not shown in the figure, actually a motor) drives the lifting seat 51 to rise and fall on the lifting guide rod 52, driving the filling hopper 2 to rise and fall. During filling, the filling hopper 2 descends, so that the discharge part 22 is inserted into the bottle body 6 through the bottle mouth, so as to avoid the powder being scattered outside the bottle body 6, thereby further improving the filling accuracy. When the motor drives the lifting seat 51 to rise and fall, there will be a certain vibration in the forward and reverse rotation of the motor, so that all the materials in the filling hopper 2 fall into the bottle body 6 to avoid sticking to the filling hopper 2; at the same time, the lifting guide rod 52 is arranged on the sliding seat 43, that is, the lifting drive mechanism 5 moves back and forth following the movement of the sliding seat 43, and finally realizes the lifting and reciprocating movement of the filling hopper 2.

[0038] Furthermore, if Figure 1 As shown, in this embodiment, the sub-filling hopper 2 is detachably connected to the lifting seat 51. It is convenient to disassemble and replace the sub-filling hopper 2, so as to adapt to bottles 6 of different shapes, and the adaptability is stronger.

[0039] Furthermore, if Figure 1 As shown, in this embodiment, there are multiple discharge nozzles 11, and each discharge nozzle 11 is provided with a corresponding sub-packaging hopper 2 below, and multiple sub-packaging hoppers 2 are arranged at intervals on the lifting seat 51. The bottle body 6 sub-packaging speed and sub-packaging capacity are improved.

[0040] Furthermore, in this embodiment, the packaging device 1 is a screw packaging device, and the powder packaging accuracy is high.

Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
