Description
Technical field
The utility model relates to a kind of injection machine feeding system, refers more particularly to a kind of central-feed system of energy-saving and noise-reducing.
Background technology
The feed of existing injection machine generally all adopts automatic feeding system, by electric control system, blanking Control Component, base and the roots blower that is connected with electric control system and other temperature controlling instruments etc., just can realize the supply of injection molding material by the feed roots blower, need not the staff supply, realize whole-course automation, when the shot in the feed temperature-controlled box dropped to fixed value, electric control system will be controlled the blower fan of feed and take out material, guaranteed continuously uninterrupted operation.
In the prior art, the roots blower that all utilizes electric control system to control feed is taken out material, method therefor is for when need not to use roots blower to take out material at present, the magnetic valve power-failure close makes system be in Light Condition in the atmosphere pipeline, and motor cuts out, when the needs roots blower is taken out material, magnetic valve energising, the solenoid closure after energising be in vacuum-pumping pipeline, and system's material-pumping tube road is opened and taken out material.In actual production process because the central-feed system is continuously uninterrupted operation, roots blower mostly is in and continues to take out the material filling, magnetic valve is in "on" position always, when need not to take out material, during closed electromagnetic valve, the blower fan closure easily causes motor reversal when taking out the material vacuum-pumping pipeline, larger to motor injury, affect service life of motor.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides to reduce motor reversal, alleviates motor injury, extends the central-feed system of the energy-saving and noise-reducing in motor service life.
The utility model is achieved through the following technical solutions:
a kind of central-feed system of energy-saving and noise-reducing, it comprises by central control board, the high pressure air pump, central authorities' pulsation dust arrester, injection machine, proportioner, central type electric eye hopper, machine limit pulverizer assembled in series forms, be equipped with vacuum breaking device on described central authorities pulsation integrator, described vacuum breaking device the first port connects central authorities' pulsation integrator, the second port connects atmosphere, the 3rd port connects the high pressure air pump, it is characterized in that: described vacuum breaking device is the two-bit triplet solenoid control, during energising, the vacuum breaking device plug is positioned at and takes out material through hole, during outage, the vacuum breaking device plug is positioned at large vent hole.
The utility model is compared with traditional vacuum breaking device load mode; reduced greatly the conduction time of magnetic valve; extended the service life of magnetic valve; and without start-up noises; effectively reduced the number of starts, especially avoided when energising vacuum breaking device be transferred to the vacuum state that extracts material by zero load, can cause the motor moment counter-rotating of high pressure air pump; to the larger phenomenon of motor injury, effectively protected motor.

Fig. 1 is the central-feed system construction drawing of energy-saving and noise-reducing described in the utility model;
Fig. 2 is the central-feed system vacuum breaking device principle assumption diagram of energy-saving and noise-reducing described in the utility model.
Fig. 3 is the central-feed system vacuum breaking device structure chart of energy-saving and noise-reducing described in the utility model.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is further illustrated, not it should be noted that the utility model is caused any restriction.
with reference to the accompanying drawings shown in 1, the central-feed system of the energy-saving and noise-reducing shown in the present embodiment, wherein the high pressure air pump 2, central authorities' pulsation dust arrester 3, the injection machine 4 of a plurality of parallel connections arranges by airduct 9 series connection, be provided with proportioner 5 on injection machine, central type electric eye hopper 6, machine limit pulverizer 7, machine limit pulverizer 7 on a plurality of injection machines 4 forms in parallel with the logical charge tube 10 of discharging bin, by the concrete feed flow process of central control board 1 electrical control whole system, the stuff level switch that detects materials is arranged on every injection machine in the central-feed system, stuff level switch is arranged on hopper, when the material level of hopper during lower than the position set, stuff level switch produces needs reinforced signal, after central control board collects reinforced signal, join and take out in the material formation, feed in raw material sequentially, when reinforced complete, in the time of need to feeding in raw material without board, the control magnetic valve energising of vacuum breaking device 8, the plug 84 of vacuum breaking device 8 is positioned at takes out material through hole 86, large vent hole 85 and high pressure air pump 2 UNICOMs, realize unloaded, in the delay time of setting, do not take out material if also there is no the board application, blower fan stops, magnetic valve continued to switch on after 2 to 3 seconds, the outage standby.
with reference to the accompanying drawings shown in 1, be equipped with vacuum breaking device 8 (Fig. 3) on described central authorities pulsation integrator 3, described vacuum breaking device 8 is middle with the cylinder promotion of " ㄣ " dividing plate 84 by the two-bit triplet solenoid control, vacuum breaking device 8 first ports 81 connect central authorities' pulsation integrator 3 by flexible pipe 9 and take out material outlet 31, the second port 82 connects atmosphere, the 3rd port 83 connects high pressure air pump 2, during outage, vacuum breaking device 8 plugs 84 are positioned at the large vent hole 85 with the second port 82 UNICOMs, with large vent hole 85 sealings, take out material through hole 86 and high pressure air pump 2 UNICOMs, during energising, vacuum breaking device 8 plugs 84 are positioned at and take out material through hole 86, large vent hole 85 and high pressure air pump 2 UNICOMs.
when the concrete method of operation of the present utility model is work, keep working continuously by high pressure air pump 2, vacuum breaking device 8 is in off-position, plug 84 is positioned on large vent hole 85, take out material through hole 86 UNICOMs, crossing through central authorities' pulsation dust arrester 3 material of taking out that filters keeps working continuously, when not needing to extract material, make vacuum breaking device 8 energisings, plug 84 is transferred to and is taken out on material through hole 86, large vent hole 85 and high pressure air pump 2 UNICOMs, realize unloaded, existing central-feed system is and works continuously, 90% time all was in material and extracts state, this moment, vacuum breaking device 8 was in off-position, 10% time was in Light Condition, Light Condition vacuum breaking device 8 just need to be in "on" position, reduced greatly magnetic valve conduction time, extended the service life of magnetic valve, in the conventional mode, outage when vacuum breaking device 8 is unloaded, vacuum breaking device 8 energisings when material extracts, vacuum breaking device 8 is transferred to the vacuum state that extracts material by zero load when energising, can cause the motor moment counter-rotating of high pressure air pump, larger to the motor injury, adopt load mode of the present utility model can prevent thoroughly the drawback of this motor reversal, and without start-up noises, effectively reduced the number of starts.
