Abstract
The utility model discloses an electromagnetic heating device of a pipeline special injection molding machine, which comprises electromagnetic coils arranged on a storage cylinder and a rotary valve oil cylinder of the injection molding machine; and the electromagnetic coils are arranged on the machine barrel, wherein the electromagnetic coils are respectively connected with an electromagnetic controller. After the above technical scheme is adopted, than traditional resistance-type heating method economize on electricity about 50%, reduced the heat time to pipeline special injection molding machine is taken as an example, and the heat time reduces more than 2/3, has improved production efficiency.
Description
Technical field
The utility model relates to a kind of electromagnetic heater, especially refers to the special-purpose injection machine electromagnetic heater of a kind of pipeline.
Background technology
The electromagnetism power-saving technology in recent years on common injection machine heating system than extensive use; Because the structure and the common injection machine difference structurally of the special-purpose injection machine of pipeline; Cause to use in recent years always; But adopt the resistance-type heating system always, its thermal losses is big, rate of warming is slow, the thermal efficiency is low.Therefore, utilize the electromagnetism heating control system to improve the special-purpose injection machine of pipeline and broken at the eyebrows and eyelashes, it can improve the thermal efficiency, reduces power consumption, reduces the time of plasticizing high density polyethylene (HDPE), enhances productivity.
Steel skeleton plastic clad pipe be a kind of with twine and the steel wire of welding fabrication as web frame, be matrix with the high density polyethylene (HDPE), and both be combined with each other equably, quantity-produced composite construction pipeline on production line.Its pipe fitting is with reel welding after the even punching of steel plate frame, with the injection moulding mode itself and high density polyethylene (HDPE) is combined with each other equably.
Shortcoming: the pipeline of above two kinds of structures all must carry out secondary in process of production and seal, and causes easily and seals weld mark, makes product quality can not reach 98% quality objective.
General common injection machine is to adopt hydraulic motor to drive screw rod promotion plastics to carry out direct injection moulding, four warm areas of heating system; And that the special-purpose injection machine of pipeline requires to annotate shot is big, and inject time is short, therefore, is added with preformed and aggregate-storing system, manys rotary valve, accumulator and nozzle warm area than common injection machine; And the rotary valve profile is a square structure, next door next-door neighbour's rotary valve oil cylinder, and the locus is little, and we adopt electromagnetic screen that oil cylinder is not heated.
Because it is in the guide pin bushing ring, to adopt the resistance-type heating that the secondary of steel skeleton plastic clad pipe seals, its temperature is uneven, causes the inside pipe wall weld mark.Adopt guide pin bushing ring electromagnetic heater can solve the weld mark problem fully.
The utility model content
The utility model proposes to above-mentioned technical problem, provides a kind of pipeline special-purpose injection machine electromagnetic heater, and said electromagnetic heater has the good advantage of heats.
It is following that the utility model solves the problems of the technologies described above the technical scheme that is adopted:
The special-purpose injection machine electromagnetic heater of a kind of pipeline comprises, is located at the accumulator of injection machine and the solenoid on the rotary valve oil cylinder; And, be located at the solenoid on the machine barrel, wherein, said solenoid is connected with electromagnetic controller respectively.
Further preferred construction is, said electromagnetic controller is connected among the electrical control cabinet, is provided with temperature control system in the said electrical control cabinet, is used to control said electromagnetic controller and solenoid and carries out all and heat.
Further preferred construction is, also is provided with heat-insulation layer, temperature probe, and wherein, said heat-insulation layer wraps on the machine barrel, and said temperature probe is in machine barrel.
Further preferred construction is between said accumulator and rotary valve oil cylinder, also to be provided with electromagnetic screen.
The utility model has been taked after the such scheme, and the resistance-type mode of heating economize on electricity about 50% than traditional has reduced heat time heating time, is example with the special-purpose injection machine of pipeline, reduces heat time heating time more than 2/3, has improved production efficiency.
Description of drawings
Through coming that below in conjunction with accompanying drawing the utility model is carried out further detailed description, above-mentioned advantage of the utility model and technique effect will become more obvious.
Fig. 1 is the sketch map of the special-purpose injection machine electromagnetic heater of the utility model pipeline.
The specific embodiment
Come the utility model is described below in conjunction with accompanying drawing and specific embodiment.
Fig. 1 is the sketch map of the special-purpose injection machine electromagnetic heater of the utility model pipeline.
As shown in the figure; Among the special-purpose injection machine of said pipeline, said injection device adopts double-clicks screw rod plunger type injection device, and plastic pellet at first plastifies through single stage screw preformed device; Get into the injection accumulator through rotary valve then; When the feed amount reaches variable, the plasticized screw stall, injection ram is injected at once.Wherein, the screw rod with mixing unit of custom-designed L/D=25 selects for use the low-speed big oil motor directly to drive plasticized screw, realizes stepless speed regulation, makes the plasticizing of high density polyethylene (HDPE) even and quick.
The electromagnetic heater of the special-purpose injection machine of said pipeline, according to Fig. 1, comprise, be located at the accumulator 1 of injection machine and the solenoid on the rotary valve oil cylinder 2; And, be located at the solenoid 4 on the machine barrel, wherein, said solenoid is connected with electromagnetic controller respectively.
And said electromagnetic controller is connected among the electrical control cabinet, is provided with the temperature control system (not shown) in the said electrical control cabinet, is used to control said electromagnetic controller and solenoid and carries out all and heating.
In the drawings, between said accumulator 1 and rotary valve oil cylinder 2, also be provided with electromagnetic screen 3.
And, also include heat-insulation layer 5, temperature probe 6, wherein, said heat-insulation layer wraps on the machine barrel, and said temperature probe is in machine barrel.
The utility model has been taked after the such scheme, can use the electromagnetism mode of heating than traditional resistance-type mode of heating economize on electricity about 50%, has reduced heat time heating time, is example with the special-purpose injection machine of pipeline, reduces heat time heating time more than 2/3, has improved production efficiency.
It should be noted that; Above-mentioned specific embodiment is exemplary; Under the above-mentioned instruction of the utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improve or distortion drops in the protection domain of the utility model.
It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of the utility model, are not to be used to limit the utility model.The protection domain of the utility model is limited claim and equivalent thereof.
