Description

Technical Field

[0001] This utility model relates to the field of powder filling cartridges, specifically an impact-type powder filling cartridge. Background Technology

[0002] The powder box is used to store powder and fill the mold cavity during pressing. When producing products with small mold cavity size or low bulk ratio materials, the powder box is prone to uneven powder filling, resulting in products that do not meet the requirements for thickness, density, etc., and the powder filling time is too long, which seriously affects the production efficiency. Therefore, new technical solutions are needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an impact-type filling powder box to solve the problems mentioned in the background art. It has the advantages of improving the stability of each filling and improving the poor flowability of low bulk ratio powders, small cavity size and difficulty in filling powder.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an impact-type filling powder box, comprising a shell, a powder box body installed inside the shell, a first rotating shaft and a second rotating shaft located on both sides of the first rotating shaft passing through the powder box body, a stirring blade sleeved on the first rotating shaft, a slanted plate blade sleeved on the second rotating shaft, and a driving component for driving the first rotating shaft and the second rotating shaft to rotate.

[0005] By adopting the above technical solution, the mold cavity is generally located directly below the stirring paddle. The powder in front and behind the powder box does not participate in filling. The addition of the inclined paddle is to stir the powder in front and behind. After the powder in the middle is filled into the mold cavity, the powder in front and behind will replenish the powder in the middle due to the movement of the paddle, ensuring that there is no shortage of material above the mold cavity. The drive component drives the first and second rotating shafts to rotate back and forth repeatedly, thereby driving the stirring paddle and the inclined paddle to rotate repeatedly. The inclined paddle is set to limit the movement. The stirring paddle will disperse the powder to prevent agglomeration and make the powder fall to fill the mold cavity. This action will be repeated multiple times to form an impact-type powder filling, ensuring the stability of each filling and improving the problems of poor flowability of low bulk ratio powder, small cavity size, and difficulty in filling powder, as well as the problem of thick products being difficult to fill.

[0006] As a further embodiment of this utility model: a gear is sleeved at one end of both the first rotating shaft and the second rotating shaft, the driving component includes a rack meshing with the gear, a moving block is fixedly connected to one end of the rack, and the outer shell is provided with a driving cylinder connected to the moving block.

[0007] By adopting the above technical solution, the drive cylinder drives the moving block to move, which in turn drives the rack to move. The movement of the rack drives the gear to rotate, which in turn drives the first rotating shaft and the second rotating shaft to rotate.

[0008] As a further improvement of this utility model: the powder box body is fixedly connected to a cylinder bracket, and the cylinder bracket is connected to a drive cylinder.

[0009] By adopting the above technical solution, the cylinder bracket provides support for the drive cylinder.

[0010] As a further improvement of this utility model: the outer shell is fixedly connected to a horizontal plate, which is sleeved on the outside of the drive cylinder.

[0011] By adopting the above technical solution, the horizontal plate can increase the stability of the drive cylinder.

[0012] As a further improvement of this utility model, the stirring paddle is configured as a spiked club structure.

[0013] By adopting the above technical solution, the design of the spiked club structure can increase the stirring capacity.

[0014] As a further embodiment of this utility model: a rear plate is threadedly connected to the rear side of the outer shell, and a sliding plate is snapped onto the rear plate, with the rear plate and the sliding plate having a damping effect.

[0015] By adopting the above technical solution, when not in use, the sliding plate can be slid to the back plate to act as a shield. When the powder box is being filled, the sliding plate will cover the opening to prevent foreign objects from entering. After filling, the powder box will retract to the position of the powder hopper (located above the powder box). Because of the limit, the sliding plate will not retract completely, so the opening will be open. The powder will fall freely from the powder hopper above into the powder box, refilling the powder box and ensuring that the powder box is full when the bottom is filled.

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

[0017] 1. The mold cavity is generally located directly below the stirring paddle. The powder in front and behind the powder box does not participate in filling. The addition of the inclined paddle is to stir the powder in front and behind. After the powder in the middle is filled into the mold cavity, the powder in front and behind will replenish the powder in the middle due to the movement of the paddle, ensuring that there is no shortage of material at the top of the mold cavity. The drive component drives the first and second rotating shafts to rotate back and forth repeatedly, thereby driving the stirring paddle and the inclined paddle to rotate repeatedly. The inclined paddle is set to limit the movement. The stirring paddle will disperse the powder to prevent agglomeration and make the powder fall to fill the mold cavity. This action will be repeated many times to form an impact-type powder filling, ensuring the stability of each filling and improving the problems of poor flowability of low bulk ratio powder, small cavity size and difficulty in filling powder, and thick product size and difficulty in filling powder.

[0018] 2. Place a paddle at the front and back of the powder filling area to allow the powder outside the mold cavity to move to the top of the cavity, ensuring sufficient powder. At the same time, add a stirring paddle with a wolf-tooth structure in the middle to break up the extruded powder, preventing bridging and agglomeration, and provide a certain downward force to help the powder enter and fill the cavity.

[0033] 2. Place a paddle at the front and back of the powder filling area to allow the powder outside the mold cavity to move to the top of the cavity, ensuring sufficient powder. At the same time, add a stirring paddle 5 with a wolf-tooth structure in the middle to break up the extruded powder, avoid bridging or agglomeration, and provide a certain downward force to help the powder enter and fill the cavity.
