Novel corrosion resistance and tearing prevention pre-embedded coil of conveying belt

Abstract

The invention proposes a novel corrosion-resistant and tear-proof pre-embedded coil for a conveyor belt, which includes a coil made of stainless steel wire, and a layer of conductive coating is provided on the surface of the stainless steel wire. The conductive plating layer is a copper plating layer, a zinc plating layer, a tin plating layer or a silver plating layer. The diameter of the stainless steel wire is 0.1-1.5mm, preferably 0.1mm. The coil is directly made of single or multiple strands of the stainless steel wire. The coil is braided into a round tube by a single stainless steel wire, and then the coil is made of the round tube. The invention has good electrical conductivity, corrosion resistance, high strength and impact resistance. Copper plating on the surface of the stainless steel wire not only solves the above problems, but also hardly increases the cost and does not require additional processing technology, so the promotion value is high.

Description

technical field [0001] The invention relates to a novel corrosion-resistant and tear-resistant pre-embedded coil for a conveyor belt. 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 . Such as 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 docks and min...

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
