Description

Technical Field

[0001] The utility model relates to the technical field of hoppers, in particular to a weighing hopper. Background Art

[0002] In the process of manufacturing products based on graphite, it is necessary to weigh the raw materials and additives. Weighing is a very important step. The ratio of raw materials and additives is the yardstick that determines the degree of qualification of the product after molding. After weighing, the raw materials and additives are put into the dry mixing equipment through the hopper for mixing.

[0003] At present, the weighing hopper weighs the raw materials first and then feeds them. Then the above weighing steps are repeated to weigh the added materials, and they are successively fed into the equipment below through the hopper. This process needs to be repeated at least twice to complete the weighing of different materials. At the same time, the materials cannot be added synchronously when replenishing, which is not conducive to the actual working steps.

The feeding table is an overall cylindrical structure with a placement slot starting from the top. The placement slot is a rectangular structure. A weighing table is installed on the bottom surface of the placement slot. The wires of the weighing table pass through the wire hole and are electrically connected to the display located at the front end surface of the feed box. A distance is left between the feeding table and the inner wall surface of the feed box, and the feeding table is sleeved on the rotating shaft.

[0011] In one embodiment, the connection line of the display has a reserved length, and the reserved line segment length is greater than the length of the rotation path of the unloading table to avoid pulling damage to the two ends of the connection line.
