A kind of edge anti-extraction mining whole core flame retardant conveyor belt

Abstract

The invention discloses a mineral whole-core fire-resistant conveyer belt with side part extraction-resistance. The mineral whole-core fire-resistant conveyer belt comprises a fabric core which is woven with a multi-weft interlocked structure; 3-4 cm of side part fabric cores (6) which are woven with a three-axial direction orthogonal interlocked structure are arranged on two sides of the fabric core; the fabric core and the side part fabric cores (6) are subjected to grinding glue dipping and vacuum glue dipping, and are fully soaked in core paste to form a framework layer (5); the framework layer (5) enters a plastifying box for plastifying and moulding; an upper part and a lower part of the moulded framework layer (5) are coated with adhesion layer paint; then the framework layer (5) enters the plastifying box again for secondary plastifying to form assistant adhesion layers (2); then covering glue material is extruded through an extruder at high temperature; the molten covering glue is extruded and attached to the high-temperature framework layer (5) and the assistant material adhesion layers (2) through a grinding tool; and finally, the molten covering glue material is rolled, cooled and sized into covering glue (1). By adopting the above structure, effects that the structure is simple; abrasion-resistance is good; side part warp extraction is reduced; and supporting rolls are prevented from being wound by side part warps are realized.

Description

technical field [0001] The invention relates to a whole-core flame-retardant conveyor belt for mines with anti-drawing-out edges. Background technique [0002] At present, during the use of the whole-core flame-retardant conveyor belt for mining fabrics, the conveyor belt often deviates from the worn edge when it is running on the conveyor. After the edge is worn, it is easy to pull out the warp at the edge of the belt core. Wrapped on the idler roller, causing serious deviation or even more serious belt drop and broken belt accidents, affecting normal production and safety. Contents of the invention [0003] The purpose of the present invention is to provide a side pullout-resistant whole-core flame-retardant conveyor belt for mines, which has simple structure, good wear resistance, reduces side warp yarn drawout and can prevent side warp yarns from wrapping around idler rollers. [0004] The technical solution of the present invention is a whole-core flame-retardant con...
