However, considering that during the powder mixing process, some powders will precipitate at the bottom of the mixing barrel, resulting in insufficient mixing and thus affecting the mixing effect. Content of the Utility Model

[0006] The purpose of the utility model is to provide a powder mixing device to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A powder mixing device includes a mixing barrel. The bottom of the mixing barrel is fixedly connected to a base. The top of the mixing barrel is fixedly communicated with a feed pipe. The bottom of the mixing barrel is fixedly communicated with a discharge pipe. A mixing mechanism is arranged inside the mixing barrel. A shunt box is arranged at the bottom of the mixing barrel.

When the extrusion block contacts the arc-shaped part of the transmission block, affected by the extrusion, the transmission block, transmission rod, pushing block, and piston will move. When the piston moves, it will compress the gas in the gas collection box, causing the gas to enter the shunt box through the transmission pipe. When the extrusion block does not contact the transmission block, the elastic force generated by the spring will drive the transmission block, transmission rod, pushing block, and piston to reset. At this time, the gas collection box is in a negative pressure state, and the gas will enter the gas collection box through the intake pipe. This cycle continues, and gas is introduced into the shunt box. When the gas in the shunt box reaches the limit of the one-way pressure valve, the gas will intermittently spray out from the spraying pipe, raising the powder from bottom to top, effectively preventing the powder from accumulating at the bottom of the mixing barrel.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1 - Figure 6 The present utility model provides a technical solution:

A mixing mechanism is arranged inside the mixing barrel 1. A flow dividing box 5 is arranged at the bottom of the mixing barrel 1. The connection between the flow dividing box 5 and the mixing barrel 1 is connected by a support block 6. The top of the flow dividing box 5 is fixedly communicated with a plurality of spraying pipes 8 through a one-way pressure valve 7. The top of the spraying pipe 8 penetrates into the interior of the mixing barrel 1;

[0030] The mixing mechanism includes a motor 9 fixedly installed on the top of the mixing barrel 1. The output end of the motor 9 penetrates into the interior of the mixing barrel 1 and is fixedly connected to a rotating rod 10. A stirring frame 11 is arranged inside the mixing barrel 1. Two scraping plates 12 are fixedly connected to the bottom of the rotating rod 10. A ramp groove 13 is formed at the top of the scraping plate 12. An air collecting mechanism is arranged at the bottom of the mixing barrel 1.

[0031] In this embodiment, considering that during the powder mixing process, some powders will precipitate at the bottom of the mixing barrel 1, resulting in insufficient mixing and affecting the mixing effect. Therefore, by setting the mixing mechanism, after the powder is placed in the mixing barrel 1, by starting the motor 9, the motor 9 will drive the rotating rod 10 and the stirring frame 11 to rotate. The dispersing rods 26 in the stirring frame 11 can make the powder fully dispersed, improving the mixing effect. At the same time, the rotating rod 10 will also drive the scraping plate 12 to rotate. When the scraping plate 12 rotates, the powder will rise upward along the slope part of the ramp groove 13, so as to avoid the powder from precipitating at the bottom of the mixing barrel 1;

[0032] It solves the problem that during the powder mixing process, some powders will precipitate at the bottom of the mixing barrel 1, resulting in insufficient mixing and affecting the mixing effect.

[0033] A bearing 25 is sleeved on the surface of the rotating rod 10, and the rotating rod 10 is rotationally connected to the inner wall of the mixing barrel 1 through the bearing 25.

[0034] In this embodiment, by setting the bearing 25, it can play a supporting role for the rotating rod 10 and improve the smoothness of the rotation of the rotating rod 10, the stirring frame 11 and other structures during the rotation process.

[0035] Dispersing rods 26 are fixedly connected to the inner wall of the stirring frame 11, and the number of the dispersing rods 26 is several.

[0036] In this embodiment, by providing a plurality of dispersion rods 26, after the stirring frame 11 drives the dispersion rods 26 to contact the powder, the plurality of dispersion rods 26 can fully disperse the powder, improving the mixing effect.

[0037] Embodiment 2:

[0038] On the basis of Embodiment 1, in this embodiment, the gas collection mechanism includes a gas collection box 14 fixedly connected to one side of the mixing barrel 1. The top of the gas collection box 14 is fixedly communicated with an intake pipe 15, the bottom of the gas collection box 14 is fixedly communicated with a transmission pipe 16, one end of the transmission pipe 16 is fixedly communicated with one side of the shunt box 5, one side of the gas collection box 14 is fixedly communicated with a push block 17, one side of the push block 17 is fixedly connected to a transmission rod 18, one end of the transmission rod 18 penetrates into the interior of the mixing barrel 1 and is fixedly connected to a transmission block 19, and the surface of the rotating rod 10 is fixedly connected with a pressing block 20 that cooperates with the transmission block 19. A spring 21 is sleeved on the surface of the transmission rod 18. One end of the spring 21 is fixedly connected to one side of the transmission block 19, and the other end of the spring 21 is fixedly connected to the inner wall of the mixing barrel 1.

[0039] In this embodiment, by providing the gas collection mechanism, when the rotating rod 10 rotates, it can drive the pressing block 20 to rotate. When the pressing block 20 contacts the arc-shaped part of the transmission block 19, affected by the extrusion, the transmission block 19, the transmission rod 18, the push block 17 and the piston 24 will move. When the piston 24 moves, it will compress the gas in the gas collection box 14, so that the gas enters the shunt box 5 through the transmission pipe 16. When the pressing block 20 does not contact the transmission block 19, the elastic force generated by the spring 21 will drive the transmission block 19, the transmission rod 18, the push block 17 and the piston 24 to reset. At this time, the gas collection box 14 is in a negative pressure state, and the gas will enter the gas collection box 14 from the intake pipe 15. This process circulates in turn to introduce gas into the shunt box 5. When the gas in the shunt box 5 reaches the limit of the one-way pressure valve 7, the gas will intermittently spray out from the spraying pipe 8 and lift the powder from bottom to top, effectively preventing the powder from accumulating at the bottom of the mixing barrel 1.

[0040] A first one-way valve 22 is fixedly installed on the surface of the intake pipe 15, and a second one-way valve 23 is fixedly installed on the surface of the transmission pipe 16.

[0041] In this embodiment, by providing the first one-way valve 22 and the second one-way valve 23, the first one-way valve 22 is a valve that can only allow gas to enter the gas collection cylinder, and the second one-way valve 23 is a valve that can only allow gas to enter the shunt box 5. When the gas in the gas collection box 14 is compressed, the gas will enter the shunt box 5 through the transmission pipe 16. When the gas collection box 14 is in a negative pressure state, the gas will enter the interior of the gas collection box 14 from the intake pipe 15.

[0042] One side of the push block 17 is fixedly communicated with a piston 24, and the material of the piston 24 is rubber.

[0043] In this embodiment, by setting the piston 24, the sealing performance in the air collecting box 14 can be improved, ensuring that a sealed cavity is formed in the air collecting box 14 to facilitate air collection and gas compression.

[0044] One side of the transmission block 19 is arc-shaped.

[0045] In this embodiment, by setting one side of the transmission block 19 to be arc-shaped, when the extrusion block 20 contacts the arc-shaped part of the transmission block 19, affected by the extrusion, the transmission block 19, the transmission rod 18, the pushing block 17, and the piston 24 will move, playing a role in transmission.

[0046] Working principle: After the user places the powder in the mixing barrel 1, by starting the motor 9, the motor 9 will drive the rotating rod 10 and the stirring frame 11 to rotate. The dispersion rod 26 in the stirring frame 11 can fully disperse the powder, improving the mixing effect. At the same time, the rotating rod 10 will also drive the scraper 12 to rotate. When the scraper 12 rotates, the powder will rise upward along the slope part of the slope groove 13, so as to avoid the powder from settling at the bottom of the mixing barrel 1;

[0047] While the rotating rod 10 is rotating, it drives the extrusion block 20 to rotate. When the extrusion block 20 contacts the arc-shaped part of the transmission block 19, affected by the extrusion, the transmission block 19, the transmission rod 18, the pushing block 17, and the piston 24 will move. When the piston 24 moves, it will compress the gas in the air collecting box 14, causing the gas to enter the shunt box 5 through the transmission pipe 16. When the extrusion block 20 does not contact the transmission block 19, the elastic force generated by the spring 21 will drive the transmission block 19, the transmission rod 18, the pushing block 17, and the piston 24 to reset. At this time, the air collecting box 14 is in a negative pressure state, and the gas will enter the air collecting box 14 from the air inlet pipe 15, and cycle in turn to intake air into the shunt box 5. When the gas in the shunt box 5 reaches the limit of the one-way pressure valve 7, the gas will intermittently spray out from the spraying pipe 8, raising the powder from bottom to top, effectively avoiding the powder from accumulating at the bottom of the mixing barrel 1.
