Powder automatic weighing machine

Abstract

The invention provides an automatic powder weighing machine, particularly relates to an automatic weighing machine suitable for weighing multiple-material powder and multiple-component powder and capable for automatically conveying to a pressure forming step. The automatic powder weighing machine comprises a mechanical system and an electric control system, and is characterized in that the mechanical system is assembled as the following manner: a material sucking device (1) is connected with a hopper (2), a filter cloth bag (3) is disposed above the hopper (2), a rotary stirrer (4) is installed in the hopper, a feeder (5) is installed at the discharge port at the bottom of the hopper, a weighing hopper (6) with a small door is hung on a weighing sensor (7) and disposed below the feeder (5), a sliding chute (17) is disposed below the weight hipper (6), and a material cup (8) is fixed on a conveyer chain (10) by a chuck (9) with equal intervals and corresponding to the sliding chute (17). The inventive machine can simultaneously weigh multiple-material and multiple-component powders and directly convey the powders to the pressure forming step via the conveying device, and the cup is automatically returned; and is very suitable for forming a production line with a multiple-position compacting press.

Description

technical field [0001] The invention belongs to an automatic weighing machine, in particular to the weighing of various materials and components suitable for powder materials, and the automatic delivery to the molding station. Background technique [0002] Powder compression molding is a production method for many mechanical parts and daily necessities. First, the powder should be weighed and then loaded into the mold. Sometimes two kinds of materials need to be loaded into the mold successively to produce double-layer products. The weight accuracy of the weighing material will directly affect the quality of the product and the utilization rate of the material. At present, most of the powder weighing is done manually, not only the labor intensity is high, the dust is flying and the environment is affected, but also the weighing error is arbitrary, which directly affects the product quality. The weighed powder has to be transported in a container such as a cup, and the cup ...

Problems solved by technology

At present, most of the powder weighing is done manually, not only the labor intensity is high, the dust is flying and the environment is affected, but also the weighing error is arbitrary, which directly affects the product quality.

The weighed powder has to be transported in a container such as a cup, and the cup has to be returned, resulting in a large amount of logistics at the production site, complicated management, and serious waste of manpower
