Said invention is characterized by that the existent extrusion equipment is improved, its original one charging hopper can be changed into two charging hoppers. Its production method adopts an on-line finalized continuous production process and includes the following several steps: using nylon 610 or nylon 1010 as base material, selecting silicon carbide or aluminium oxide whose grain size rage is 100-1000 meshes as abrasive, using silane coupling agent to make imbibition treatment, drying and mixing said abrasive with nylon according to a certain mixing ratio, feeding, plasticizing, melting, extruding, drawing, finalizing, packaging so as to obtain the invented product.

Description

The manufacture method of grinding material of nylon brush thread and extrusion equipment

Technical field

The present invention relates to a kind of manufacture method and extrusion equipment thereof of grinding material of nylon brush thread.

Background technology

Occur production equipment when producing grinding material of nylon brush thread at home and abroad at present and very easily be subjected to the grievous injury phenomenon, cause great waste, increased the weight of production cost greatly.Because when adopting conventional blend feed process, abrasive powder directly and screw cylinder carry out dry friction, screw cylinder very easily is worn, and produces 1 ton of grinding material of nylon brush thread product generally speaking and must change extruder screw barrel one cover.Production efficiency is very low in addition, production time is long, output is also very low, and conventional method can only adopt Batch Process to cause the extremely low of production efficiency, produce the 6kg/h counting generally speaking, after producing the 150kg left and right sides semi-finished product every day, carry out carrying out the drawing and forming second time again after the infiltration about 2 days is by a definite date handled.Drawing and setting needs one day equally for the second time, in fact produces the 150kg product at least 4 day time.

Summary of the invention

The objective of the invention is to solve to produce in the grinding material of nylon brush thread process, the very easily impaired problem of production equipment occurs, and the production efficiency of prior art is low, the long and problem that yields poorly of time provides a kind of manufacture method of grinding material of nylon brush thread.

Another object of the present invention provides the extrusion equipment that uses in a kind of grinding material of nylon brush thread manufacturing.

For realizing above-mentioned first purpose, the technical scheme of taking is to adopt the continuous production processes flow process of online typing, the manufacture method of this grinding material of nylon brush thread according to the following steps:

(1) be base stock with NYLON610 or nylon 1010, abrasive material is the 20--30% of material gross weight, nylon and abrasive material are adopted the method for separating independent self-feeding, inject first hopper of extruder and second hopper at middle part respectively, nylon enters screw cylinder after after the extruding, plasticizing, fusion by screw rod transmission to the second hopper place, abrasive material enters barrel to be mixed with nylon, plasticizing, extrude the spray silk;

(2) Pen Chu monofilament enters the water tank cooling and shaping, carry out entering first drawing machine after the branch silk dewaters then under the effect of training beautiful jade, enter second drawing machine again and carry out stretching the first time after the baking of first hot bellows, multiplying power is 2.5-3.3 times, the temperature of hot bellows is 120-230 ℃

Next enter the baking of heating of second hot bellows, temperature is 130-240 ℃, enters then in the 3rd drawing machine to stretch, and multiplying power is 1.1 times,

Then enter the 3rd hot bellows and the 4th hot bellows and carry out the hot blast typing, the temperature of the 3rd hot bellows is 120-230 ℃, and the temperature of the 4th hot bellows is 120-200 ℃,

Batch at last with cutting after unclog and readjust packing, finished product.

Described abrasive material is to select particle size range in 100-1000 purpose carborundum Sic or aluminium oxide Al ₂O ₃, after silane coupler soaks into processing, oven dry.

The NYLON610 that adopts or nylon 1010 be base-material, its content is at 70-80%.

For realizing another object of the present invention, the technical scheme of taking is that this extrusion equipment comprises blower fan, support, motor, transmission device, reduction box, hopper, screw rod, barrel, heating plate, automatic feeding, die head and stabilized pressure pump, blower fan and motor are installed in the below of support, one side of support is installed transmission device, the top that reduction box is installed in support is connected with transmission device, screw rod and barrel one end are connected with reduction box, the other end of barrel connects die head and stabilized pressure pump, the place, top of described barrel is provided with first hopper, its charging aperture is communicated with barrel, the middle part is provided with second hopper, between this hopper and the barrel automatic feeding is housed, the periphery of described material letter is provided with heating plate.

During prior art processing grinding material of nylon brush thread, usually the method that adopts is with behind abrasive powder and the nylon blending, the charging aperture that together injects extruder carries out feeding, and very big to the screw cylinder damage at extruder charging aperture place like this, the density of NYLON610 or nylon 1010 is 1.05-1.14 gram/cm ³, and the density of abrasive powder is 3.95 gram/cm ³Though generally speaking through blend, but because the abrasive powder volume is little of great, the abrasive material composition easily is deposited on feed hopper bottom, cause abrasive powder and screw cylinder to carry out regular dry friction, this is the major reason that screw cylinder very easily damages, and fact proved, the reason that at every turn changes screw cylinder during production all is because the screw cylinder at charging aperture place is impaired, and all the other are then excellent.The present invention improves extruder, in process of production, nylon and abrasive material be separate feeds respectively, owing to annotate people's nylon earlier through in screw cylinder, pushing, plasticizing is injected abrasive material by the middle part of screw cylinder after the fusion again, can guarantee that like this screw cylinder is not subjected to because the infringement that dry friction causes between abrasive material and the screw cylinder, can prolong hundreds and thousands of times service life, greatly reduces production cost.In addition, adopt online typing quantity-produced streamline to make grinding material of nylon brush thread, can enhance productivity greatly.

Because producing is successively to carry out, and tens of monofilament of production stretch simultaneously at every turn, so the PR conventional method is high, adopt advanced production equipment in addition, the constant product quality of producing and superior.
