Further, a guide block matched with each support sliding block is provided in the annular support guide groove.

Further, a support roller corresponding to the guide block is provided on the right side of the lower end of each support slider.

Further, the left side of the guide block is an arc-shaped wedge-shaped block portion, the right side of the guide block is an arc-shaped platform portion, and the right side of the upper end of the arc-shaped platform portion is provided with an arc-shaped groove corresponding to the supporting roller.

Further, the drive assembly includes a drive motor, and a gear part is provided on the outer upper part of the ring support. The drive motor is drivingly connected to the gear part on the ring support through the gear transmission assembly, and the drive motor is fixed on the ring support.

Further, a second support roller is provided on the left side of the upper end of the support block, the top of the second support roller is higher than the height of the upper platform of the support block, and the right side of the lower end of the fixing ring is provided with a second support roller top and a support block Lower raised platform with matching top height difference.

Further, the lower end of the fixed ring is provided with a second arc-shaped groove matching the second supporting roller.

Further, a rubber support pad is provided at the lower end of the guide groove.

Compared with the prior art, the utility model has the following beneficial effects:

1. The lifting mechanism composed of the added fixed ring, support slide block, support block, and drive mechanism can lift the mixing tank when the platform scale is not weighing, and fasten it to the support between the fixed ring and the positioning part When weighing, the mixing tank is supported by the weighing rack and placed on the platform scale for weighing. Since the mixing tank does not contact the components on the fixed ring when weighing, the accuracy of the weighing will not be affected. It ensures the accuracy of weighing and at the same time ensures the service life of the platform scale.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, not all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

Referring to Figures 1-3, a mixed ingredient weighing equipment, including a platform scale 6, a support frame 1, a weighing frame 7, is characterized in that the center of the support frame 1 is fixedly provided with an annular support guide groove 2, which 2 is provided with a ring support 10 above, and at least three support sliders 8 fixed on the ring support 10 are evenly arranged between the lower end of the ring support 10 and the ring support guide groove 2, and the upper end of the ring support 10 is provided with each support slide The supporting block 9 corresponding to the block 8 is provided with a mixing tank 15 in the inner ring of the annular bracket 10, and a fixing ring 11 fixed on the peripheral side of the mixing tank 15 is arranged above each supporting block 9.
