Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a quantitative powder feeding mechanism. Background Art

[0002] Pueraria root powder is a traditional Chinese medicine made by grinding the tuberous roots of the leguminous plant Pueraria lobata with water. It is in the form of long cylindrical or plate-like thick flakes, usually off-white or light yellow, with a rough surface and containing a large amount of fiber. It has the effects of relieving fever, relieving restlessness, promoting salivation, and quenching thirst, so it is often processed into products for bulk sales. During the preparation process, the kudzu root powder needs to be packaged and processed for sale. However, the methods used in the prior art to control material delivery, such as solenoid valves or electric butterfly valves, have problems and cannot guarantee the precise discharge of the required quantitative powder because the friction between the material and the equipment affects the discharge. To this end, we propose a quantitative powder delivery mechanism. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] See also Figure 1-Figure 7 The utility model provides a technical solution: a quantitative powder feeding mechanism, comprising a transmission belt 1 and a hopper 11 arranged above the transmission belt 1, the hopper 11 being fixedly connected to the mounting frame of the transmission belt 1, and further comprising:

[0031] Multiple storage boxes 2 are evenly and equidistantly arranged on the transmission belt 1. The transmission belt 1 is started to drive the storage boxes 2 to move;

[0032] The docking member 3 is provided on the discharge pipe of the hopper 11 and is used to dock the storage box 2 with the hopper 11;

[0033] The valve assembly 4 is provided on the hopper 11 and is used to open the hopper 11 and fill the powder into the storage box 2;

[0034] The driving member 5 is provided on the hopper 11 and is connected to the docking member 3 and the valve assembly 4 to drive the docking member 3 and the valve assembly 4 to work in sequence;

[0035] During specific use, the specially made storage box 2 is transported to the bottom of the hopper 11 by the transmission belt 1, and then the driving member 5 drives the hollow tube 31 downward to dock the hopper 11 with the storage box 2. Then, the valve assembly 4 is opened to allow the powder to fall freely into the storage box 2. After a certain period of time, when the storage box 2 is full of powder, it continues to move with the transmission belt 1 and pours the powder into the package, ultimately achieving the purpose of precise quantitative transportation;

[0036] At the same time, the elastic member 33 cooperates with the hollow cylinder 32 to ensure that the storage box 2 is accurately aligned with the hopper 11 to avoid leakage of powder.

[0037] The docking member 3 includes a hollow tube 31 that is sleeved on the discharge pipe of the hopper 11. The hollow tube 31 is slidably connected to the discharge pipe of the hopper 11. A hollow cylinder 32 is fixedly connected to the bottom end of the hollow tube 31. The hollow tube 31 is moved to sleeve the storage box 2.

[0038] The inner wall of the hollow cylinder 32 adopts a sloped design, and an elastic member 33 is provided between the storage box 2 and the transmission belt 1. The hollow tube 31 is moved downward to drive the hollow cylinder 32 to move, and the slope of the inner wall of the hollow cylinder 32 is used to push the storage box 2 to move relative to the transmission belt 1. At the same time, the elastic member 33 is compressed and deformed to provide it with self-restoring elastic force. This design avoids the possibility that the transmission belt 1 is insufficient in precision and cannot accurately drive the storage box 2 to move to the bottom of the discharge pipe of the hopper 11, thereby ensuring that the storage box 2 is accurately aligned with the hopper 11, avoiding leakage of powder, so that the main body of the device can operate stably.

[0039] The elastic member 33 includes a rectangular plate 34 fixedly connected to the transmission belt 1, a slide rod 35 fixedly connected to the rectangular plate 34, a slide sleeve 36 fixedly connected to the bottom end of the storage box 2, the slide rod 35 passes through the slide sleeve 36, and the slide rod 35 is located on both sides of the slide sleeve 36 and is sleeved with springs 37, and the two ends of the spring 37 are respectively in contact with the slide sleeve 36 and the rectangular plate 34, thereby allowing the storage box 2 to have a certain amount of movement space relative to the transmission belt 1.

[0040] The valve assembly 4 includes a plurality of fan-shaped plates 38 fixedly connected to the end of the discharge pipe of the hopper 11, and a slide tube 39 is slidably connected in the discharge pipe of the hopper 11. One end of the slide tube 39 is also fixedly connected to a plurality of fan-shaped plates 38. The slide tube 39 is rotated so that the fan-shaped plates 38 on the slide tube 39 overlap with the fan-shaped plates 38 on the hopper 11 to open the hopper 11, and vice versa to close the hopper 11.

[0041] The driving member 5 includes an electric push rod 41 fixedly connected to the hopper 11. A ring 42 is rotatably connected to the hollow cylinder 32. The ring 42 is fixedly connected to the extended end of the electric push rod 41. When the electric push rod 41 is started, the ring 42 moves, thereby driving the hollow tube 31 to move.

[0042] A chute 43 is provided on the inner wall of the hollow tube 31, a cylinder 44 is fixedly connected to the slide tube 39, an arcuate groove 45 is provided on the discharge pipe of the hopper 11, one end of the cylinder 44 slides through the arcuate groove 45, and is located in the chute 43 and slidably connected to its inner wall;

[0043] A guide groove 46 is provided on the outer wall of the hollow tube 31, a strip plate 47 is fixedly connected to the hopper 11, one end of the strip plate 47 is fixedly connected to a cylinder 2 48, one end of the cylinder 2 48 is located in the guide groove 46, and a spiral groove 49 connected to the guide groove 46 is provided on the outer wall of the hollow tube 31. In the process of moving the hollow tube 31, the cylinder 2 48 is driven to slide along the guide groove 46, and then the cylinder 2 48 is driven to slide along the arc groove 45, so that the hollow tube 31 drives the slide tube 39 to rotate.
