[0036] In order to solve the technical problems in the prior art that as the discharge pipe continuously transports the flux into the packaging box, the flux entering the packaging box is usually in a cone shape, and the staff is required to shake the cone-shaped flux pile inside the packaging box to make it even, which is inconvenient to use and the overall packaging efficiency of the flux is low, the utility model provides a flux packaging weighing device, which enables the flux to be dispersed in the packaging box, maximizes the guarantee that the flux is dispersed to various places in the packaging box, thereby avoiding accumulation into a cone shape, eliminating the need for staff to shake the packaging box, and improving packaging efficiency.

[0039] In this example, see Figures 1 to 3 , a discharge port 11 is provided at the lower end of the material tank 1; the stirring device 2 has a rotatable stirring portion, and the stirring portion is provided in the material tank 1; the upper end of the discharge pipe 3 is rotatably installed on the discharge port 11 along the axis in the vertical direction, and the discharge pipe 3 is transmission-connected to the stirring portion, and the lower end of the discharge pipe 3 is provided with two outlets 34 that are arranged deviating from its axis, and the two outlets 34 are at different distances from the axis of the discharge pipe 3; the valve 4 is provided on the discharge pipe 3; the weighing assembly 5 is located below the discharge pipe 3, and is used for placing the packaging box 200 for weighing.

The flux discharged from the two outlets 34 forms two inner and outer rings in the packaging box 200. As the discharge continues, the flux can be dispersed in the packaging box 200, which maximizes the dispersion of the flux to various places in the packaging box 200, thereby avoiding accumulation in a cone shape. There is no need for staff to shake the packaging box 200, thereby improving packaging efficiency.

[0045] In this embodiment, the second discharge tube 32 and the third discharge tube 33 are both arranged at an angle, and the angles between them and the central axis of the first discharge tube 31 are α and β respectively. In order to ensure that the flux can be evenly diverted to the second discharge tube 32 and the third discharge tube 33, α and β are the same. In order to ensure that the flux output from the two outlets 34 falls at different positions in the packaging box 200, the vertical distances from the lower ends of the second discharge tube 32 and the third discharge tube 33 to the central axis of the first discharge tube 31 are a and b, where a is greater than b.

The upper and lower ends of the connecting shaft are respectively connected to the stirring shaft 21 and the first discharge pipe 31 through the gear sets, thereby driving the first discharge pipe 31 to rotate through gear meshing.

[0052] Specifically, the gear group includes a first gear and a second gear that mesh with each other, wherein the first gear in one gear group is fixedly mounted on the stirring shaft 21, and the second gear is fixedly mounted on the upper end of the connecting shaft; the first gear in the other gear group is fixedly mounted on the outer periphery of the first discharge pipe 31, and the second gear is fixedly mounted on the lower end of the connecting shaft.

Then, the connecting pipe 6 is welded to the first discharge pipe 31, and then the connecting pipe 6 is extended into the material tank 1 from the discharge port 11, so that the external spline 62 at the upper end of the connecting pipe 6 is docked with the spline hole, and then the first discharge pipe 31 is installed at the discharge port 11.

The four limiting protrusions 52 enclose a placement area, and the center of the placement area is arranged opposite to the discharge port 11. The placement area is used for placing the packaging box 200.

[0059] In this embodiment, since the two outlets 34 are eccentrically arranged, in order to prevent the material from spilling out, a placement area is defined on the weighing platform 51, and the center of the placement area is opposite to the central axis of the first discharge tube 31. During specific use, the packaging box 200 is placed in the placement area to ensure that the center of the packaging box 200 is always opposite to the central axis of the first discharge tube 31, thereby preventing the material from spilling out.

During the rotation of the discharge pipe 3, the two The outlet 34 makes a circular motion around the axis of the first discharge tube 31. During the discharge process, the flux is dispersed in a ring shape in the packaging box 200 as the outlet 34 rotates, and the distances between the two outlets 34 and the axis are different. The flux discharged from the two outlets 34 forms two inner and outer rings in the packaging box 200. As the discharge continues, the flux can be dispersed in the packaging box 200, which maximizes the dispersion of the flux to various places in the packaging box 200, thereby avoiding accumulation in a cone shape. There is no need for staff to shake the packaging box 200, which improves packaging efficiency.
