A lifting feeding device

Abstract

The invention discloses a lifting-type feeding device. The lifting-type feeding device comprises a rack, a lifting driving mechanism, a material loading bin and an electric control box; the lifting driving mechanism comprises two screw rod components and a motor for driving the screw rod components; each screw component comprises a screw rod, an upper lifting block and a lower lifting block, an the upper lifting block and the lower lifting block are installed on the screw rod; the upper ends of two side surfaces of the material loading bin are respectively hinged with the upper lifting blocks of the two screw rod components by fixing rods; the lower parts of two side surfaces of the material loading bin are respectively provided with air cylinders for driving the material loading bin to turn over and pour materials; output shafts of the air cylinders are hinged with the lower lifting blocks at the same side correspondingly; the upper part of the rack is also provided with stroke switches for detecting whether the material loading bin is in place. The lifting-type feeding device provided by the invention is small in occupied area by adopting a vertical structure; the screw rods are driven by the motor, so that the material loading bin ascends to be in touch with the stroke switches; the motor stops, the air cylinders move so as to enable the material loading bin to turn over and pour materials; in the process, because materials are conveyed by the lifting of the material loading bin, the materials are conveyed stably without the problem of material falling.

Description

technical field [0001] The invention relates to the technical field of waste cable recovery equipment, in particular to a lifting feeding device for sending waste circuit boards to a feed port of a crusher. Background technique [0002] At present, my country's recycled copper resources account for a large proportion of my country's total copper resources. Under the environment of advocating resource regeneration and environmental protection in my country, the waste recycling industry is developing rapidly, and various equipment for processing waste materials are also Take the recycling of waste wires and cables as an example, usually after cutting and crushing, the plastic and metal are separated by a shaker to achieve the purpose of metal recycling. The recovered metals are mixtures of copper, iron, etc., and they need to be further separated. [0003] In the specific crushing operation, because the feed inlet of the crusher is relatively high, the waste circuit board gene...

Problems solved by technology

[0003] In the specific crushing operation, because the feed inlet of the crusher is relatively high, the waste circuit board generally has to send the material to the feed inlet of the crusher manually, or manually shovel the material onto the belt and then convey it by the belt; During belt transmission, waste circuit boards are easy to fall from both sides of the belt, which is easy to hurt people and troublesome to clean up, or slips backward due to insufficient friction with the belt surface
