The invention relates to the technical field of safety helmet production, and discloses a blending proportion guaranteeing and material shortage preventing assembly for resin safety helmet production.The blending proportion guaranteeing and material shortage preventing assembly comprises a stirring shaft, wherein the outer side of the stirring shaft is fixedly connected with a concentric disc; and the stirring shaft is movably connected with trigger swing arms through fixing plates, and the trigger swing arms are movably connected with trigger supporting handles through arc-shaped empty grooves formed in the inner sides of the trigger swing arms. According to the blending proportion guaranteeing and material shortage preventing assembly for resin safety helmet production, through eccentric bounce of the stirring shaft, the trigger supporting handles on the outer side of the stirring shaft moves outwards under impact of the stirring shaft and makes contact with electrode plates I, conductive columns drive the electrode plates I to move outwards so as to be connected with special-shaped inserting grooved in an inserted mode, and pole changing plates are magnetized under the action of the current and coils, so that the pole changing plates move outwards, the speed reduction is realized, then the overspeed of the stirring shaft is limited, and therefore the mixing effect of resinmaterials is perfected.
Description
technical field [0001] The invention relates to the technical field of production of safety helmets, in particular to a guarantee and proportion anti-shortage material component for the production of resin safety helmets. Background technique [0002] The safety helmet is a kind of labor protection product, which is composed of a cap shell, a cap lining, a lower chin strap and a rear hoop. The cap shell is hemispherical, firm, smooth and has a certain degree of elasticity. Bear, and the shell is often made of ABS resin material. [0003] The Chinese utility model patent with the publication number CN209937371U and the publication date of January 14, 2020 discloses a production equipment for modifying PS / ABS, including a top plate, a front shell, a rear shell, a bottom plate, a support frame, and a stirring motor , rotating shaft 2 and stirring paddles, the top plate and the bottom plate are respectively welded on the top and bottom plate of the rear shell, the bottom plate ...
