Auto-revolving screw immersion plating machine

Abstract

The invention provides an automatic screw rotary dipping machine, comprising a cabinet which is provided with a dip-coating device with an integrated bucket. An elevating gear is arranged at one side of the cabinet, which can drive the dip-coating device to elevate; a rotating device is arranged on the top of the cabinet; and a feeding device, a tilting device, a push-pull device and a centrifuge device are arranged at the side ends of the cabinet. A charging basket is arranged on the feeding device, and the screw to be dip-coated is put into the charging basket and the basket is lifted and pushed into the cabinet by the push-pull device to carry out the dip-coating operation of rust resisting paint. At the same time, the charging basket on the silting device is put into the feeding device and descended down, after the dip-coating operation is completed, the charging basket is pulled out by the push-pull device and the paint dip-coated screws are poured into the centrifuge device to rotate and blend, so as to lead the rust resisting paint to be evenly adhered on the screw surfaces, thus achieving good dip-coating rust resisting paint effect and improving the quality of products.

Description

technical field [0001] The present invention relates to an automatic screw dipping machine, in particular to a fully automatic operation of feeding, immersion plating, discharging, pouring out and centrifugal spin-off, so that the anti-rust paint can be more evenly attached to the surface of the screw. Screw automatic spin dipping machine. Background technique [0002] After the screw is molded, a layer of protective film can be formed on the surface of the screw by immersion plating. In order to achieve the anti-rust effect, the existing screw immersion plating method is to put the formed screw into the barrel, and the surface of the barrel is equipped with For perforation, put the bucket into the bath of anti-rust paint, make the anti-rust paint adhere to the surface of the screw through the perforation, then take out the bucket and put it in a dehydrator to remove the anti-rust paint, so that the excess The anti-rust paint is thrown off, so as to complete the anti-rust t...

AI Technical Summary

Problems solved by technology

[0003] The surface treatment of the above-mentioned screw immersion plating, including putting the screw into the barrel, entering the bath, taking it out and putting it in the dehydrator for spin-off treatment, and taking out the treated barrel, is all done by manpower. The method is difficult to program control in terms of time, so it is difficult to obtain ideal parameters, and it is difficult to grasp the quality only with the traditional experience of the master, so it is not conducive to improving work efficiency

[0004] Furthermore, the barrel is immersed in the anti-rust paint bath and taken out and placed in the dehydrator to remove the excess anti-rust paint, which is also limited by the plane rotation of the water tank of the dehydrator, that is, the The placed screw will be close to the inner wall of the barrel, so that the anti-rust paint will be concentrated on the arc surface of the screw or the thread of the nut, resulting in uneven adhesion of the anti-rust paint, and when the anti-rust paint dries up Finally, due to the expansion of water vapor pressure inside the anti-rust paint covering the thicker parts, the anti-rust paint forms a raised film and is easy to fall off. criticize
