Description

Technical Field

[0001] The utility model relates to the technical field of powder raw material mixing, in particular to a powder raw material crushing and mixing device. Background Art

[0002] Powder material crushing and mixing equipment is a widely used device in industrial production. Its main function is to crush and mix various powder materials to form the desired granular material. This equipment is widely used in my country's chemical, food, and pharmaceutical industries, facilitating the production of various powder products.

[0003] The existing crushing roller type powder raw material mixing device has poor mixing efficiency for some powder raw materials with lighter weight. When crushing the powder raw materials, the crushing roller of the powder raw material mixing device mainly utilizes the gravity of the powder raw material itself and the friction between the crushing roller and the shear force and other mechanical forces. When the raw material passes between the two relatively rotating crushing rollers, the raw material particles are subjected to pressure, extrusion and shearing from the surface of the roller, thereby achieving material crushing. However, when the raw material has a lighter weight, the friction between the raw material and the crushing roller is insufficient, which causes the crushing roller to be unable to crush the raw material well.

[0022] In this embodiment, when the powder raw material needs to be crushed, the first drive mechanism 13 and the second drive 16 are started to operate the pushing mechanism 4 and the crushing roller group 6, and the raw material is put into the crushing box 2. The guide plate 3 guides the raw material to the pushing mechanism 4, and then falls onto the crushing roller group 6. The pushing mechanism 4 applies thrust to the raw material on the crushing roller group 4, thereby accelerating the crushing efficiency of the crushing roller group 6 for the lighter raw material, greatly improving the crushing effect of the powder raw material crushing and mixing device on the lighter raw material, and the crushed raw material falls into the mixing box 1 and is stirred and mixed by the mixing box 1.

[0023] like Figure 2 As shown, the interior of the mixing box 1 is provided with a mixing chamber 7 which is connected with the interior of the crushing box 2. A rotating shaft 8 is rotatably provided inside the mixing chamber 7. A plurality of stirring rods 9 are fixedly provided on the outer wall of the rotating shaft 8.

[0025] In this embodiment, the first driving mechanism 13 drives the two sets of rotating shafts to rotate in opposite directions, and the two sets of rotating shafts rotate in opposite directions to drive the pushing blades 5 to push the raw materials toward the crushing roller group 6.

[0026] like Figure 1 and Figure 3 As shown, the first driving mechanism 13 is a first shell fixedly arranged on the outside of the crushing box 2, and two groups of first gears 14 are meshed and installed inside the first shell. The axes of the two groups of first gears 14 are connected to the ends of the corresponding rotating shafts. A first motor 15 is fixedly arranged on the outside of the first shell, and the output end of the first motor 15 passes through the interior of the first shell and is fixedly connected to the axis of one group of first gears 14.

[0027] In this embodiment, the first shell provides an installation position for two groups of first gears 14. By starting the first motor 15, one group of first gears 14 is driven to rotate. The rotation of one group of first gears 14 drives the other group of first gears 14 to rotate.

By starting the second motor 18, one group of second gears 17 is driven to rotate, and one group of second gears 17 drives the other group of second gears 17 to rotate. The two groups of second gears 17 rotate in opposite directions, thereby driving the crushing roller group 6 to rotate in opposite directions.
