Description

A kind of PEEK sticking plaster production equipment and process
Technical field
The invention discloses a kind of PEEK sticking plaster production equipment and process.
Background technology
The extrusion molding of PEEK rod is that granular material is joined in the machine barrel of extruder by hopper, material is under the extruding impetus of screw rod rotation, rubbing action by machine tube inner wall and screw surface is fed forward and compacting, by heater and the friction preheating of machine barrel outside, fusion plastification under high temperature, condition of high voltage.Then, the screw rod rotating continuously pushes extrusion die fused materials again, and the fused materials of extruding from extrusion die becomes required PEEK goods through cooling and shaping.
Production equipment and technique were as follows in the past:
Shown in PEEK rod extrusion molding production line Fig. 1, the composition of PEEK stick extrusion machine forming production line:
The production line that PEEK rod is extruded is comprised of main frame, subsidiary engine two parts, and these parts are called extrudes unit.Wherein main frame is an extruder, consists of: extrusion system, rotation system, control system following three parts.Extrusion system is gun barrel screw rod, adopts special-purpose equidistant gradation type PEEK extrusion screw rod, and screw slenderness ratio is 30:1, and compression ratio is 3.Rotation system is mainly comprised of motor and reduction box.Motor rotation, drives reduction box by belt transmission, thereby makes screw rod keep certain shear rate.The control system major electrical equipment instrument of extruder and executing agency form, and its Main Function is main control system, makes the rotating speed of its operation and power normal, and guarantees the quality of temperature, pressure, flow and the goods of main and auxiliaries, realizes the automatic control of full unit.Subsidiary engine: the composition of extruder is according to the kind of goods and fixed, general subsidiary engine is comprised of following several parts: single excellent mould, hauling machine, cutter sweep.Mould: mould is assembled by flange, handpiece body, setting cylinder, cooling water tank; The raw material of melting enters handpiece body under the effect of screw rod rotational shear, by horn mouth, transfers spiral melting material to linear pattern enter forming tube moulding at certain pressure, under the effect of cooling water, solidifies, shapes.Hauling machine is mainly comprised of transmission device, roller hold down gag and braking device; Be arranged on attemperator after, by connecting rod, mould and hauling machine are fixed together, upper and lower 4 pair rollers of gas control hauling machine processed compress sheet materials, reductor drags roller makes goods in compressional zone, keep certain pressure at the uniform velocity to advance.Cutting machine is bar cutting equipment, is arranged on after pipe mold outlet, and the goods of extruding are through the cutting supporting surface of cutting machine, and the High Rotation Speed cutting bar by saw blade, is cut into needed length.
The production process of extrusion molding is: feed intake → dry → plastify extrude → moulding/sizing → traction → cutting/stacking.
(1) feed intake: feed intake in time, guarantee that hopper is not empty.Different material can not be used with, and the type of the trade mark and the material of material is distinguished in attention, prevents that foreign material, assorted material from entering hopper, causes feed opening to stop up.
(2) dry: because PEEK resin suction temperature is larger, must get rid of moisture content through entering to be dried processing, otherwise its water content surpasses certain limit before extrusion molding, moisture content will evaporate into gas in extruder barrel, makes goods inside contain pore, and intensity declines.Adopt 130 ℃ of circulating airs to be dried PEEK material, be 4-6H drying time, makes water content in product lower than 0.2%.
(3) plasticizing is extruded: by the effect of barrel zone temperature and screw rod, material changes the process that evenly melt is extruded continuously with certain fluidity into.Fen San heats to machine barrel in district, according to raw material characteristics design temperature: district's feeding section temperature a: 380-390 ℃; Two melting compression section, district temperature: 390-400 ℃; Three district's homogenizing zone temperature: 390-400 ℃; Joint: 390-400 ℃; Extrusion screw rod speed: 4-6r/min.
(4) moulding/sizing: there is the improving uniformity of melt of mobility, because the rotary squeezing of screw rod enters mould by porous plate, and by being extruded mould after the type embryo forming of definite shape, sizing.1. mould compressional zone is divided into 4th district and carries out constant temperature, and just melt keeps certain viscosity moulding, that is: handpiece body temperature: 320-330 ℃; 2. at the two ends of mold cools down shaping area, be all connected to cooling circulating water, the continuous circulation by cold water constantly reduces the temperature of melt, and final set crystallization sizing is extruded mould.
(5) traction: drag PEEK rod by hauling machine, bar is at the uniform velocity advanced under pressure constant state, guarantee the stability of product quality.
(6) cutting/windrow: measure 1000MM length with tape measure, start cutting machine, cut out needed length, bar is neatly overlayed on specific rickstand.Between rod and rod layer, be placed with stainless square steel, square steel between layers seems preferably point-blank up and down.
Existing problems have: 1, Surface of Rod Bar piebald, Hei Quan; 2, surperficial unrestrained trace, scratch; 3, inner yellow core; 4, bar color is partially yellow; 5, bad mechanical property; 6, bar is crooked serious; 7, production efficiency is low.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of PEEK sticking plaster production equipment and process is provided.
To achieve these goals, the present invention adopts following technical scheme:
A PEEK sticking plaster production equipment, comprises main and auxiliaries, and described main frame is an extruder, and it comprises extrusion system, rotation system, control system; Described extrusion system is gun barrel screw rod; Described rotation system comprises motor and reduction box; Describedly comprise that control system comprises electrical instrumentation and executing agency; Described subsidiary engine comprises mould, hauling machine, oil temperature machine, cutting machine, baking box; Described mould comprises main mould, deflector, insulating collar, moulding sizing cylinder and cooling water tank; Described oil temperature machine is arranged on the sizing section of formed pipe; Described hauling machine mainly comprises transmission device, roller hold down gag and braking device, it be arranged on attemperator after; Described cutting machine is arranged on after mould outlet; Described baking box is the casing of sealing.
