Automatic feeding device used by brake pad formation

Abstract

The invention discloses an automatic feeding device used by brake pad formation, which comprises a rack, and a feeding unit and a weighting unit arranged on the rack, wherein the feeding unit comprises a material barrel and a spiral convey shaft arranged in the material barrel; a hopper is arranged at a feed port of the material barrel; the spiral convey shaft comprises a shaft rod and spiral feeding blades; a plurality of backspacing holes are formed in the feeding blades; the weighting unit comprises a weighting container positioned below a discharge port and an electronic scale below the weighting container; two paralleled first slide tracks are arranged on the weighting platform face of the electronic scale; the weighting container and the first slide tracks are in sliding connection; a gate valve is arranged at the bottom of the weighting container; the rack is further provided with two second slide tracks positioned above a mould; the second slide tracks and the first slide tracks are coaxially arranged; the rack is provided with a convey air cylinder driving the weighting container, and a discharging air cylinder capable of connecting the gate valve. The device has the advantages that the weighting precision is high, and materials are not easy to block; the over-all structure is simple, and the working efficiency is high.

Description

technical field [0001] The invention relates to an auxiliary device for mold forming, in particular to an automatic feeding device for forming brake pads. [0002] Background technique [0003] Automobile brake pads usually include four major parts: binder, reinforcing fiber, friction modifier, and filler. During manufacture, the materials are usually premixed first, and then a predetermined weight of powdered premixed material is placed in the cavity of the mold. Afterwards, it is pressed and formed on a press. In the prior art, people mostly put in raw materials manually, which not only has high work intensity and low efficiency, but also makes it difficult to ensure the accuracy of weighing. [0004] A "brake pad multi-cavity mold premix automatic weighing, packaging and feeding device" is disclosed in the Chinese patent literature. The publication number is CN102173088A. The device includes a frame, a stirring feeding unit, a weighing unit, and a cloth unit, storage u...
