[0025] Example

[0026] On the one hand, the feeding is realized by only setting a feeding hopper at a single feeding port, which causes the powder to enter from a single feeding port and accumulate inside the mixing equipment, thereby making the mixing efficiency low;

[0027] Secondly, the size of the feed port cannot be adjusted, and it cannot be adjusted according to the mixing requirements of different powders, which limits the scope of use.

[0028] To do this, see Figure 1-3 The utility model provides a bulk powder mixing device, comprising: a mixing tank 1, two symmetrically arranged feed ports at the top of the mixing tank 1 are fixedly connected with feed square tubes 2, the tops of the two feed square tubes 2 are closed, and the feed ports of the two opposite side walls of the two feed square tubes 2 are fixedly connected with lateral square tubes 3, and the tops of the lateral square tubes 3 are fixedly connected with a feeding hopper 31, and a motor a4 fixedly connected to the center of the top of the mixing tank 1 is provided between the two feed square tubes 2, and the lower end output shaft of the motor a4 extends into the mixing tank 1 and is fixedly connected with a stirring shaft 41, and the bottom end of the stirring shaft 41 is fixedly connected with a stirring blade 42, and a two-directional intermittent feeding structure 6 is connected between the upper end output shaft of the motor a4 and the two feed square tubes 2, and the two-directional intermittent feeding structure 6 can make the powder in the two feeding hoppers 31 intermittently enter the mixing tank 1 from two different positions;

[0029] The feed amount adjustment structure 7 is installed on the inner side of the mixing tank 1. The feed amount adjustment structure 7 can adjust the sizes of two symmetrically arranged feed ports.

[0030] Further Figure 1 As shown, it is worth explaining in detail that a discharge pipe 5 is fixedly connected to the discharge port at the bottom end of the mixing tank 1, and an electric valve is installed on the discharge pipe 5.

[0031] Among them, by starting the electric valve, the mixed powder in the mixing tank 1 can be discharged.

[0032] Further Figure 1 and 3 As shown, it is worth explaining in detail that in order to enable the powder in the two feeding hoppers 31 to intermittently enter the mixing tank 1 from two different positions, a two-directional intermittent feeding structure 6 is set up, including a slanted plate 64 fixed on the upper output shaft of the motor a4, and two guide balls 63 are movably overlapped on the inclined surface of the bottom end of the slanted plate 64. The two guide balls 63 are fixed with L-shaped connecting plates 62 through connecting columns, and the two L-shaped connecting plates 62 are fixed with baffle plates 61 at the opposite ends, and the baffle plates 61 are movably inserted in the top end of the feeding square tube 2, and the bottom ends of the L-shaped connecting plates 62 are connected to the top end of the feeding square tube 2 through springs 65.

[0033] Among them, the two guide balls 63 are in single-point contact with the bottom inclined surface of the inclined plate 64. When the inclined plate 64 rotates, the two guide balls 63 are squeezed in turn, so that the L-shaped connecting plates 62 drive the corresponding baffle plates 61 to descend, thereby blocking the outer feed port of the lateral square tube 3, as shown in the accompanying drawings, so that the powder in the two feed hoppers can enter the mixing tank 1 in turn, greatly reducing the stirring time and improving the mixing efficiency.

[0034] Further as Figure 1-2 As shown, it is worth specifically explaining that, in order to be able to adjust the size of the two feed ports at the top of the mixing tank 1, a feed amount adjustment structure 7 is provided, which includes an adjustment disk 71 rotatably connected to the inner top wall of the mixing tank 1, and the adjustment disk 71 is movably sleeved on the outer side of the stirring shaft 41 through a sleeve hole provided in the middle, and a guide ring 78 is fixedly connected to the top of the adjustment disk 71, and both ends of the vertical section of the guide ring 78 are inverted "isosceles trapezoidal" structures, and the guide ring 78 is slidably connected to the annular guide groove provided on the inner top wall of the mixing tank 1 Two symmetrically arranged large holes 72 and two symmetrically arranged small holes 74 are provided on the adjusting disk 71, and two symmetrically arranged middle holes 73 are provided between the two large holes 72 and the two small holes 74. A gear ring 75 is fixedly connected to the outer side of the adjusting disk 71, and a gear 76 is meshedly connected to the outer side of the gear ring 75. A motor b77 is fixedly connected to the left side of the top of the mixing tank 1. The motor b77 is a stepping motor. The output shaft of the motor b77 extends into the mixing tank 1 and is fixedly connected to the mounting shaft hole of the gear 76.

[0035] Among them, the motor b77 drives the gear 76 to rotate a fixed angle and transmits the ring gear 75, so that the large hole 72, the middle hole 73 and the small hole 74 on the adjustment disk 71 can correspond to the bottom of the feed port respectively, thereby realizing the adjustment of the feed port size.

[0036] In summary: when using the loose powder mixing equipment, first, the powders to be mixed are inverted into the two feed hoppers respectively. Secondly, by starting the motor a4, the stirring shaft 41 drives the stirring blades 42 to rotate and stir, and at the same time, the inclined plate 64 rotates, and the two guide balls 63 are squeezed in turn, so that the L-shaped connecting plates 62 drive the corresponding baffle plates 61 to descend, and the spring 65 is compressed, so that the outer feed port of the lateral square tube 3 is blocked, as shown in the accompanying drawings, so that the powders in the two feed hoppers can enter the mixing tank 1 in turn, which greatly reduces the stirring time and improves the mixing efficiency, so that the two baffle plates 61 are upper left and lower right or The movement state of the lower left and upper right allows the powder in the two feeding hoppers 31 to intermittently enter the mixing tank 1 from two different feed ports, thereby greatly improving the mixing efficiency of the powder and achieving good use effect. Furthermore, when it is necessary to adjust the size of the two feed ports at the top of the mixing tank 1, the motor b77 can be started to rotate the gear 76 to a fixed angle and transmit the gear ring 75, so that the large hole 72, the middle hole 73 and the small hole 74 on the adjustment disk 71 can correspond to the bottom of the feed port respectively, thereby realizing the adjustment of the feed port size, which is convenient and effective to adjust the feed port size according to the mixing requirements of different powders and has a wide range of uses.

[0037] Motor a4 and motor b77 can be purchased on the market. Motor a4 and motor b77 are equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.
