Novel conveying belt corrosion resistant and impact resistant anti-tear embedded coil

Abstract

The invention provides a novel conveying belt corrosion resistant anti-tear embedded coil. The novel conveying belt corrosion resistant anti-tear embedded coil comprises a coil, wherein the coil is made of a stainless steel wire, a conductive coating is applied to the surface of the stainless steel wire, the conductive coating is a copper coating, a zinc coating, a tin coating or a silver coating,the diameter of the stainless steel wire is 0.05 to 1.5 mm, and preferably, the diameter of the stainless steel wire is 0.1 mm; the coil is prepared in the steps of stranding a single stainless steelwire or a plurality of stainless steel wires so as to be prepared into a cord thread with the diameter of 0.5 to 2 mm and then processing into a spiral shape, a flat spiral shape or a sine wave shape; the coil is prepared by processing the single stainless steel wire into the spiral shape, the flat spiral shape or the sine wave shape; and the coil is reprocessed by weaving the single stainless steel wire or the multistrand stainless steel wire into a shape of a circular tube. The novel conveying belt corrosion resistant anti-tear embedded coil has the advantages of good conductivity, corrosion resistance, high strength and impact resistance and has a high popularization value, and copper is plated on the surface of the stainless steel wire, so that the problem is solved, the cost is almost not increased, and an additional treatment process is not needed.

Description

technical field [0001] The invention relates to a novel conveyor belt corrosion-resistant, impact-resistant and tear-resistant pre-embedded coil. Background technique [0002] The rubber conveyor belt is a long flat and thin object installed on the conveyor. The structure is that there is a skeleton layer 1 in the middle, and the upper and lower sides are protected by a rubber covering layer 2. Under the skeleton layer 1, there are embedded coils 3 . like figure 1 shown. According to the material of the skeleton layer, there are canvas core (with nylon, polyester or cotton cloth in the middle) and steel cord conveyor belts. The conveyed materials will inevitably have sharp objects, and the pierced belt body will be caught between the idlers. Because the conveyor belt is moving, the material will be scratched If it is not found in time, the entire conveyor belt will be completely torn and cause equipment accidents. Conveyor belt tearing accidents have occurred in many dock...

2. The resistance value of the closed coil is small and the signal is strong

However, after comprehensive consideration of various materials, there is no material that can meet the above requirements at the same time.

Stainless steel wire is corrosion-resistant, high in strength and impact-resistant, but compared with steel wire, its resistance value is very large. After testing, the stainless steel cord with the same structure and diameter as the copper-plated steel cord is used to make an induction coil with the same structure. The reflection signal is too weak, the detection device cannot detect the induction signal, and the use requirement cannot be met
