Description
Technical field
The utility model relates to a kind of melt insulation transfer docking instrument, particularly relates to the equipment technical field that the plastic shaping such as extruder, moulding press is used.
Background technology
Because polymer melt is very easily lowered the temperature solidification, in the sample preparation and large-scale mouldings manufacture field of the research of the polymer modification such as thermoplastic and rubber, after raw material are carried out melt modification granulation by formula by many employings, again plastic grain is applied to injection mo(u)lding, or adopts and particulate material placed in compression molding instrument, carry out heating and mould pressing in a mold shaping.When adopting injection moulding, need to clean injection machine and material resides in injecting machine material tube, large to experiment material requirement amount, this checking for a small amount of additive performance of autonomous synthesis causes very large inconvenience, then high to equipment requirement but also can impact the orientation of bath component when producing large-scale mouldings, directly affects the physical property of product.When adopting the direct compression molding of particulate material, because material will could realize melt-flow in a mold extruding than routine the processing temperature high and longer heat time, such polymer is at high temperature heated repeatedly and for a long time, not only efficiency is low, material also thermo-oxidative ageing degraded very easily occurs, and these class methods of the very difficult employing of large-scale super thick mouldings are shaping or very easily produce defect.
Summary of the invention
In view of the problems referred to above faced in current high polymer modifying plastics manufacture field, the purpose of this utility model is a kind of easy melt insulation transfer docking instrument of design.
The purpose of this utility model realizes like this, described a kind of melt insulation transfer docking instrument, comprise and receive discharge system and heating system, it is characterized in that 1) described receipts discharge system comprises barrel, piston, hydraulic stem, left-hand cylinder lid and right cover, described piston to be installed in barrel and can to slide in barrel, described right cover is connected with barrel by screw thread, described hydraulic stem one end is connected with the piston being placed in barrel through after right cover, described left-hand cylinder lid is connected with barrel by screw thread, and feeding pipe is connected with barrel one end through after left-hand cylinder lid; 2) described heating system is made up of electromagnetic induction coil and thermocouple, and described electromagnetic induction coil is looped around on the outer wall of barrel; Described the installation of TC is in the through hole of through barrel outer wall, and described thermocouple is electrically connected with electromagnetic induction coil.
Outside the outer wall of barrel, be provided with heat-insulation layer, be outside equipped with thermal insulation layer at heat-insulation layer; Outside thermal insulation layer, heat insulation layer is set.
The inlet channel being provided with straight-through feeding pipe is covered at left-hand cylinder.
Advantage of the present utility model is: the utility model adopts syringe-type structure, simple to operate, docking can be carried out to the stream extruded from extruder to extract, electromagnetic heating system can be incubated the thermoplastic materials melt obtained, simultaneously, the melt that syringe hydraulic stem structure can be come extraction carries out injection and is transferred to the follow-up equipments such as moulding press, metering is convenient, there is the performance of good adiabatic heat-insulation, and small volume, so can realize the light safe transfer of hot melt, there is the advantages such as efficient, energy-saving and environmental protection.
In laboratory research, or in production process, the former plastic raw materials of various shape, by after fragmentation, carries out thawing modification granulation for subsequent use.So in this course, from raw material to granulation for subsequent use need to material carry out heating cooling, in follow-up production or research process, need again to heat again plastic pellet, cool again, sometimes more procedure calls is also had to composite, so just make material that thermal oxide very easily occurs and decompose, or heat fatigue creep occurs, thus have impact on the properties of material.Such as, in the lab, the stream extruded from extruder is after granulation cooling, deliver to down one molding apparatus and carry out mold pressing film-making, after cooling, study material properties, the molded tablet not reaching performance requirement is recycled again, in the process of being recycled again repeatedly to plastics carry out heating cooling.Just imagine, if there is transfer equipment a kind of like this, directly can the molten plastic extruded from extruder be transferred in moulding press, without the need to etc. the next process unit that just plastic melt can be transferred to be cooled, so neither affect material property, greatly save the experimental work time again, raise the efficiency.Melt insulation transfer docking instrument mentioned by the utility model, extracts plastic melt from extruder extrusion, and carries out Electromagnetic Heating insulation to it, dock injection subsequently and be transferred in next process unit.
Described melt transfer device is stainless steel syringe piston hydraulic pressure bar structure.Described translator offers a through hole to go directly barrel drum outer wall, built with a thermocouple thermometer, so can be convenient to Real-Time Monitoring and show current melt temperature value.The left side of barrel offers feeding pipe, feeding pipe periphery is provided with external thread structure and an aperture, internal thread on feeding pipe external screw thread and left end cover is interconnected and screws, and the right-hand member outer ring of barrel is provided with a thread segment, and this thread segment is connected with right-hand member cover; Described left end cover offers an inlet channel, when cover and material taking mouth screw tighten time, the aperture of inlet channel and feeding pipe is docked and connected, realize communicate with feeding pipe, barrel; Described air inlet, before equipment work, can pass into the protective device of suitable ammonia as translator; Described right-hand member cover offers a through hole, changes through hole requirement aperture and is less than piston diameter and is greater than hydraulic stem diameter, so that piston hydraulic pressure bar can move to low order end and not depart from barrel; The outer tube wall of described melt transfer device is provided with electromagnetic induction coil, just magnetic field line is cut when hydraulic stem moves back and forth, thus achieve electrical heat tracing; Described electromagnetic heating coil is outside equipped with one layer of heat preservation material, is incubated barrel; Described heat-insulation layer skin is provided with one deck thermal insulation layer, prevents heat trnasfer and thermal losses; Described thermal insulation layer skin is provided with one deck heat insulation layer, thus realize can human contact; Described piston hydraulic pressure bar structure is threaded connection, require that piston can move back and forth flexibly, the phenomenon that gets stuck is there is not with material tube inner wall, requirement hydraulic stem is stainless steel, dissection can be produced to magnetic field line, and measurement scale line is carved with on hydraulic stem, the material body volume collecting and inject discharge can be read.
