Abstract
The invention discloses a special extruder for surface glue of a two-sided four-layered veneering whole-core inflaming retarding conveying belt, solving the problem that an existing device only can be used for single-layered veneering. The special extruder is characterized in that a left upper extruder and a right upper extruder with the same structure are arranged on a left lower extruder and a right lower extruder through upper-layer extruder fixing brackets; the left upper extruder and the right upper extruder are used for coating inner-layer buffering glue layers on a belt core of a conveying belt; the left lower extruder and the right lower extruder are used for coating outer-layer covering glue layers again; a coating mould is a two-sided four-layered coating mould; four sets of speed-reducing gear boxes are used in opposite faces two by two; each speed-reducing gear box is driven by a variable frequency motor. The inner layer of the prepared conveying belt is a buffering layer, has a good sticking performance with a belt core and has good elasticity and plasticity; the outer layer is a wear-resisting layer, has good friction performance, and is wear-resisting and anti-impacting; the thickness is adjustable in a range of 8mm-24mm; the width of a product can be adjusted in a plurality of specifications from 650mm to 2200mm by using the coating moulds with different mould lip widths; the special extruder is long in service life and good in mould forming property; the covering glue is not easy to drop off, the friction coefficient is great and the loading angle is great.
Description
Technical field
The present invention relates to a kind of zone face rubber extruding machine of carrying, relate to or rather a kind of two-sided four layers of compound rubberizing PVC/PVG unitary-core flame-resistant conveying belt specific side glue and apply the crowded extrusion equipment of wiping.
Background technology
Along with the needs of colliery safety requirements such as fire-retardant and antistatic to coal conveyer belt, domestic PVC/PVC flame retardant conveyor belt uses and is extensively promoted.Through China's enterprise's years of researches and exploration, the production development level place advanced international standard of whole core flame retardant conveyor belt, can meet the instructions for use in colliery.Two stages have been experienced in the production of difficult combustion band for many years: the one, and the production of whole core PVC conveyer belt.This technique be through the impregnated belt carcass of thickener first in baking oven plasticizing, go out after baking oven with two extruders through the good PVC plastic coat of baking at band wicking surface, through cooling, traction, curling finished product.The 2nd, the whole technique of production of whole core PVG conveyer belt is identical with the production of PVC band, but coating material is rubber and plastic compound material, has solved band surface elastic low, the problem that coefficient of friction is little.The whole nation many Jia Nanrandai manufacturer mostly adopts the new technology of continuous vulcanization.A recent period of time, colliery has proposed the requirement of large conveying quantity, high inclination-angle to adhesive tape, we conduct in-depth research the service condition of whole core flame retardant conveyor belt for many years, find individual layer veneer by continuous vulcanization explained hereafter fire-retardant with the life-span low, when use in winter, due to the cold brittleness of plastics, to cause conveyer belt groove forming character poor, rubber cover easily becomes piece to come off, and zone face is smooth, the little phenomenon such as to cause loading angle little, wear-resisting, impact resistance is poor of coefficient of friction.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art provides a kind of two-sided four laminating surface unitary-core flame-resistant conveying belt face glue dedicated extruders, and can not only produce by Continuous Flow waterline, and once realize the sulfuration of four layers of rubber cover, compact conformation, rationally distributed.
The present invention includes extruder guide rail, lower-left extruder, bottom right extruder, head tank, coating die, lower-left extruder, bottom right extruder are arranged on extruder guide rail, and every extruder all comprises extruder barrel, screw rod, head tank, reduction gear box, heating system, cooling blower, variable-frequency motor; It is characterized in that: at lower-left extruder, upper left extruder, upper right extruder are set by upper strata extruder fixed support above the extruder of bottom right, upper left extruder, upper right extruder are identical with the structure of lower-left extruder, bottom right extruder; Described upper left extruder, upper right extruder apply internal layer cushion gum layer to conveyer belt belt carcass, and described lower-left extruder, bottom right extruder apply outer covering glue layer again; Described coating die is double-deck four sides coating die; Four described reduction gear boxes divide into groups between two opposite use, respectively driven by a variable-frequency motor.
The head tank of each described screw barrel is that transparent polycarbonate material is made, and reinforced situation is very clear, has avoided lacking because of artificial origin the quality problems of expecting to cause product zone face starved.
Operation principle: described upper left extruder, the machine barrel of upper right extruder, screw rod can constantly become molten by heating, extruding plastics or rubber and plastic pellet and be pushed into head and be coated on plasticizing rear carrier belt carcass by mould, form internal layer cushion gum layer; In like manner, the screw barrel of lower-left extruder, bottom right extruder becomes plastics or rubber and plastic pellet into molten by adding hot extrusion, becoming film through mould is again coated on hose lining, form outer covering glue layer, complete two-sided four layers of surfacing process, realize the conveyer belt crowded wiping moulding of the sulfuration of each two aspect glue up and down.
As shown from the above technical solution, the conveyer belt internal layer that the present invention makes is cushion, and good with belt carcass bond properties, elasticity and plasticity are better; Skin is wearing layer, and frictional behaviour is good, shock-resistant; Thickness range is adjustable from 8-24mm, and the coating die of different die lip widths makes the product width can be adjustable to 2200mm plurality of specifications from 650mm; Conveyer belt life of product is long, and groove forming character is good, rubber cover difficult drop-off, and coefficient of friction is large, loading angle is large, wear-resisting, impact resistance is strong.
