Description

Technical Field

[0001] This utility model relates to the field of food and pharmaceutical packaging technology, specifically to a continuous powder dispensing system. Background Technology

[0002] Existing powder dispensing systems, such as the detachable screw dispensing head with announcement number CN215323360U, are limited by the characteristics of the powder, which prevents the packaging material from moving continuously. The material needs to stop at the dispensing station for a period of time for dispensing, so only an intermittent dispensing method can be used, resulting in low dispensing efficiency and reduced powder dispensing capacity. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a continuous powder dispensing system that improves dispensing efficiency and dispensing capacity.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A continuous powder dispensing system includes a dispensing device and a dispensing hopper, the dispensing hopper being located below the dispensing device. The dispensing device is equipped with a discharge nozzle, and also includes a bottle conveying mechanism and a moving drive mechanism. The bottle conveying mechanism is used to convey bottles, and the moving drive mechanism is used to drive the dispensing hopper to reciprocate along the bottle conveying direction. The length L of the inlet of the dispensing hopper in the bottle conveying direction is greater than the sum of the conveying distance A required for the bottle to reach a preset filling amount and the length B of the discharge nozzle in the bottle conveying direction. The conveying distance is the product of the single-bottle dispensing time of the dispensing device and the conveying speed of the bottle conveying mechanism.

[0006] As a further improvement to the above technical solution:

[0007] The dispensing hopper includes a guiding section and a discharging section located at the bottom of the guiding section. The discharging section is connected to the bottom of the guiding section. The inlet end of the guiding section is a long strip arranged along the conveying direction of the bottle, and the outlet end is circular.

[0008] L is the maximum diameter of the elongated inlet.

[0009] The feeding section is cylindrical, and its diameter is equal to the diameter of the outlet end of the guiding section, but smaller than the diameter of the bottle mouth.

[0010] The feeding nozzle extends into the dispensing hopper.

[0011] The moving drive mechanism includes a support frame, a lead screw, a sliding seat, and a rotary drive for driving the lead screw to rotate. The lead screw is rotatably mounted on the support frame, the sliding seat is slidably mounted on the support frame and threadedly connected to the lead screw, and the dispensing hopper is connected to the sliding seat.

[0012] The continuous powder dispensing system also includes a lifting drive mechanism for driving the dispensing hopper to rise and fall. The lifting drive mechanism includes a lifting seat, a lifting guide rod, and a lifting drive for driving the lifting seat to rise and fall on the lifting guide rod. The lifting guide rod is located at both ends of the sliding seat, and the dispensing hopper is connected to the lifting seat.

[0013] The dispensing hopper is detachably connected to the lifting seat.

[0014] The feeding nozzle is provided in multiple ways, and each feeding nozzle is provided with a corresponding dispensing hopper below it. The multiple dispensing hoppers are arranged at intervals on the lifting base.

[0015] The dispensing device is a screw dispensing device.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] This utility model discloses a continuous powder dispensing system. The inlet of the dispensing hopper is always located below the discharge nozzle, allowing for continuous material intake. The bottle conveying mechanism continuously transports bottles, while the moving drive mechanism drives the dispensing hopper to move along with the bottles throughout the dispensing process, achieving tracking feeding. After the previous batch of bottles is dispensed, the next batch of bottles is fed in. Dispensing can begin immediately after the dispensing hopper is reset, without any waiting time. This results in high dispensing efficiency and improved dispensing capacity. Attached Figure Description

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

[0030] The dispensing process of this continuous powder dispensing system is as follows: Bottle conveying mechanism 3 conveys bottle bodies 6, first as... Figure 3As shown, the dispensing hopper 2 is in the initial position. When the bottle 6 is conveyed to the outlet of the dispensing hopper 2, the dispensing device 1 begins to feed the bottle into the dispensing hopper 2 through the feeding nozzle 11, and then... Figure 4 As shown, the moving drive mechanism 4 drives the dispensing hopper 2 to move along with the conveying of the bottle 6 until the bottle 6 is fully filled. At this point, as shown... Figure 5 As shown, bottle 6 continues to be conveyed forward, while the moving drive mechanism 4 drives the dispensing hopper 2 to move in the reverse direction, starting the reset process, and finally... Figure 6 As shown, after the reset is completed, it returns to the initial position and waits for the next batch of bottles 6 to be delivered directly below, repeating the above dispensing steps.

[0031] In this continuous powder dispensing system, the inlet of the dispensing hopper 2 is always located below the discharge nozzle 11, allowing for continuous material intake. The bottle conveying mechanism 3 continuously conveys the bottles 6, while the moving drive mechanism 4 drives the dispensing hopper 2 to move along with the bottles 6 throughout the dispensing process, achieving tracking feeding. After the previous batch of bottles 6 is dispensed, the next batch of bottles 6 is fed in. Dispensing can begin immediately after the dispensing hopper 2 is reset, without any waiting time. This results in high dispensing efficiency and improved dispensing capacity.

[0032] Furthermore, such as Figure 2 As shown, in this embodiment, the dispensing hopper 2 includes a guiding section 21 and a discharging section 22 located at the bottom of the guiding section 21. The discharging section 22 is connected to the bottom of the guiding section 21. The inlet end of the guiding section 21 is an elongated strip arranged along the conveying direction of the bottle body 6, and the outlet end is circular. The elongated shape of the inlet end of the guiding section 21, compared to a circular shape, can reduce the diffusion and exposure of powder to a certain extent, protect the dispensing powder, and improve the dispensing accuracy.

[0033] Furthermore, such as Figure 2 As shown, in this embodiment, L is the maximum diameter of the elongated inlet. The maximum diameter of the elongated inlet is greater than the sum of the conveying distance A required for the bottle 6 to reach the preset filling amount and the length B of the dispensing nozzle 11 in the conveying direction of the bottle 6. This allows for the completion of the dispensing process, shortening the length of the dispensing hopper 2 in the conveying direction and resulting in a more compact structure.

[0034] Furthermore, such as Figure 2 As shown, in this embodiment, the feeding part 22 is cylindrical, and its diameter is equal to the diameter of the outlet end of the guiding part 21, but smaller than the diameter of the bottle mouth of the bottle body 6. This facilitates the docking and positioning of the feeding part 22 with the bottle mouth of the bottle body 6, ensuring that all the powder in the feeding part 22 can be fed into the bottle body 6 through the bottle mouth, and preventing powder from spilling outside the bottle mouth, which would affect the dispensing accuracy.

[0035] Furthermore, in this embodiment, the feeding nozzle 11 extends into the dispensing hopper 2. This further reduces powder diffusion and exposure, protects the dispensed powder, and improves dispensing accuracy.

[0036] Furthermore, such as Figure 1 As shown, in this embodiment, the moving drive mechanism 4 includes a support frame 41, a lead screw 42, a sliding seat 43, and a rotary drive for driving the lead screw 42 to rotate. The lead screw 42 is rotatably mounted on the support frame 41, and the sliding seat 43 is slidably mounted on the support frame 41 and threadedly connected to the lead screw 42. The dispensing hopper 2 is connected to the sliding seat 43. The rotary drive (not shown in the figure) drives the lead screw 42 to rotate, causing the sliding seat 43 to move on the support frame 41, thereby driving the dispensing hopper 2 to reciprocate. The structure is simple.

[0037] Furthermore, such as Figure 1 As shown, in this embodiment, the continuous powder dispensing system also includes a lifting drive mechanism 5 for driving the dispensing 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 located at both ends of the sliding seat 43, and the dispensing hopper 2 is connected to the lifting seat 51. The lifting drive (not shown in the figure, but actually a motor) drives the lifting seat 51 to rise and fall on the lifting guide rod 52, which in turn drives the dispensing hopper 2 to rise and fall. During dispensing, the dispensing hopper 2 descends, allowing the feeding part 22 to be inserted into the bottle body 6 through the bottle mouth, preventing powder from scattering outside the bottle body 6 and further improving dispensing accuracy. When the motor drives the lifting seat 51 to rise and fall, the forward and reverse rotation of the motor will cause a certain amount of vibration, which makes it easy for all the material in the dispensing hopper 2 to fall into the bottle body 6 and avoid sticking to the dispensing hopper 2. At the same time, the lifting guide rod 52 is set on the sliding seat 43, that is, the lifting drive mechanism 5 moves back and forth with the movement of the sliding seat 43, ultimately realizing the lifting and reciprocating movement of the dispensing hopper 2.

[0038] Furthermore, such as Figure 1 As shown, in this embodiment, the dispensing hopper 2 and the lifting seat 51 are detachably connected. This facilitates the disassembly and replacement of the dispensing hopper 2, thereby adapting to bottles 6 of different shapes and increasing its adaptability.

[0039] Furthermore, such as Figure 1 As shown, in this embodiment, multiple feeding nozzles 11 are provided, and each feeding nozzle 11 is provided with a corresponding dispensing hopper 2 below it. The multiple dispensing hoppers 2 are arranged at intervals on the lifting seat 51. This improves the dispensing speed and dispensing capacity of the bottle 6.

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

[0041] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
