Production device of plastic coated compensation chain

Abstract

The invention relates to the technical field of plastic coating of compensation chains, and particularly discloses a production device of a plastic coated compensation chain. The production device comprises a traction mechanism, and a first-pass heating system, a second-pass heating system, an atomization cooling system, a water cooling system and an air cooling system which communicate with one another, wherein the compensation chain is sequentially treated through the first-pass heating system, the second-pass heating system, the atomization cooling system, the water cooling system and the air cooling system under traction of the traction mechanism; a plastic coating liquid tank is arranged between the first-pass heating system and the second-pass heating system; and the plastic coatingliquid tank is used for performing plastic sucking on the compensation chain. According to the production device, the structure is simple, arrangement is compact, maintenance is convenient, manufacturing cost is low, and production efficiency is high; the heating manner of the compensation chain is changed into electromagnetic heating, so that the heating speed is increased, and electric energy consumption is reduced; a drying oven adopts high-temperature resistant heating pipes, so that the space of an oven body is decreased, and stability of the temperature and the device is improved; and the atomization cooling system is additionally arranged, so that a quick cooling function is achieved, and the plastic coating cooling effect is improved.

Description

Technical field [0001] The invention relates to the technical field of plastic dipping for compensation chains, in particular to a production equipment for dipping compensation chains. Background technique [0002] Compensation chain is generally used in elevators. Its structure is steel chain wrapped with PVC rubber composite material, which is used to compensate the weight of steel wire rope and make elevator run smoothly. In order to make the elevator run safely and smoothly and achieve the effect of quietness and comfort, the compensation chain is usually noise-reducing. At present, a cheap and effective dipping compensation chain has appeared in the existing technology. The dipping compensation chain is mainly It is formed by dipping the surface of the compensation chain with a dipping liquid, which is plasticized on the surface of the compensation chain. However, because the shape of the compensation chain is not fixed, it is difficult to continuously and evenly dipping PVC...

Problems solved by technology

[0004] The production and processing of the impregnated compensation chain is formed by heating the iron chain, then dipping into liquid PVC, wrapping a layer of PVC on the surface of the iron chain, and finally heating and plasticizing the PVC on the surface; the current heating method of the impregnated equipment is electric heating tube Heating, the oven is built with refractory bricks, and the cooling is air-cooled and water-cooled; the defect of this processing equipment is that it takes 4 hours to warm up the equipment after the electric heating tube is heated and turned on, and the power consumption is large; the oven is made of refractory bricks, The space is large, and the temperature stability is within ±10°; the cooling effect of air cooling and water cooling needs to be improved
