Powder mixing device

[0013] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] like figure 1 As shown, a powder mixing device according to the present invention includes: a support 9, an airtight mixing cylinder 5, and a rolling seat formed by a concentric inner cylinder 2 and an outer cylinder 1, and the two ends of the airtight mixing cylinder 5 are respectively A rotating shaft 6 is provided, and a pair of lugs 91 are provided on the support 9, and the pair of rotating shafts 6 are respectively arranged on the corresponding side of the support through bearings (conventional technology, not shown in the figure). On the ear 91, the support 9 is also provided with a geared motor 7 as a power device on one side of the closed mixing tube 5, and the output shaft of the geared motor 7 is connected to the corresponding side of the closed mixing tube 5 through a coupling 8. A pair of support arms 92 are provided on the side of the support 9 facing away from the airtight mixing cylinder 5. The pair of support arms 92 are pierced with a rolling shaft 12, and a rolling shaft 12 is provided on the rolling shaft 12. For the gear 3, the rolling seat is provided with an arc-shaped roller table 15 matched with the rolling shaft 12 and a rolling groove matched with the rolling gear 3 (belonging to conventional technology, not shown in the figure), and the rolling shaft 12 is bound in the arc-shaped roller table 15, the driving gear 4 meshing with the rolling gear 3 is arranged in the rolling seat, the axis line of the drive gear 4 coincides with the axis line of the arc-shaped roller table 15, and the A stirring shaft 13 is also arranged along the axis of the rotating shaft 6 in the closed mixing cylinder 5, as figure 2 As shown, the stirring shaft 13 is provided with a spiral stirring blade 14, and the two ends of the stirring shaft 13 are respectively connected with the rotating shaft 6 on the corresponding side; in this embodiment, the arc-shaped roller table 15 is symmetrical on both sides A pair of limit seats 10 are provided, and a spring hole is provided on the upper end surface of the limit seat 10, and a buffer spring 11 is arranged in the spring hole, and the buffer spring 11 extends out of the limit seat 10 in a free state.

[0015] During practical application, the drive gear 4 is driven by another geared motor. When in use, the geared motor is transmitted to the rolling gear 3 through its output shaft and the drive gear 4, and the support 9 is lifted to the highest point of the arc-shaped roller table 15, and then the support 9 is allowed to carry the closed mixing tube 5 Sliding down freely to the left or right, during the sliding process of the airtight mixing cylinder 5, the raw material moves downward under the action of gravity, at the same time, through the positive and negative rotation of the gear motor 7, the forward or reverse rotation of the stirring shaft 13 Turn, let the helical stirring blade 14 push up against the moving direction of the raw material, so that the raw material is rolled in the closed mixing barrel 5.

[0016] The above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
