Abstract
The utility model discloses a novel evacuating device for an EVA foaming former, which mainly comprises an electric cabinet, a vacuum electro connecting pressure gauge, a vacuum pump, a check valve, a vacuum tank, a plurality of solenoid valves and a plurality of sets of mould cavities. The novel evacuating device is characterized in that: the electric cabinet is connected with the vacuum pump of which the air suction port is connected with the check valve; the check valve is connected with the vacuum tank; the electric cabinet is connected with the vacuum tank through the vacuum electro connecting pressure gauge; the vacuum tank is connected with the plurality of solenoid valves; and each solenoid valve is connected with a mould cavity respectively. Through the novel evacuating device, the overhigh temperature rise of the vacuum pump can be effectively avoided, the service life of the vacuum pump can be prolonged, and the energy is saved.
Description
Technical field
The utility model relates to a kind of EVA foaming machine, relates in particular to a kind of novel vacuum extractor of EVA foaming machine.
Background technology
At present, the vacuum extractor that uses on EVA foaming machine mainly is to adopt oily circulation sliding vane rotary vacuum pump, does not need though oily circulation sliding vane rotary vacuum pump can turn round continuously to shut down, and there are following 3 deficiencies in this mode: 1, waste energy; 2, oily circulation sliding vane rotary vacuum pump temperature is easy to raise, and causes oil sealing aging rotten with recycle oil; 3, the blade of the oil mist separator in the oily circulation sliding vane rotary vacuum pump is damaged easily, has had a strong impact on the service life of oily circulation sliding vane rotary vacuum pump.
Summary of the invention
In order to remedy above-mentioned deficiency, the utility model provides a kind of novel vacuum extractor of EVA foaming machine, it is too high that it can avoid that the temperature of vavuum pump rises, thereby reduce the aging speed of oil sealing effectively, and can avoid recycle oil rotten effectively, thereby really prolong the service life of whole vavuum pump, energy savings.
In order to achieve the above object, the utility model is taked following concrete technical measures: a kind of novel vacuum extractor of EVA foaming machine, it mainly comprises electric cabinet, the vacuum electro connecting pressure gauge, vavuum pump, check valve, vacuum tank, a plurality of electromagnetic valves, many molds die cavity, it is characterized in that, electric cabinet is connected with vavuum pump, the air entry of vavuum pump is connected with check valve, the purpose that check valve is set is to prevent the vavuum pump suck-back when vavuum pump shuts down, check valve is connected with vacuum tank again, realize being connected by the vacuum electro connecting pressure gauge between electric cabinet and the vacuum tank, on the vacuum electro connecting pressure gauge can play the vacuum of vacuum tank carried out, the effect of lower limit control, vacuum tank is connected with a plurality of electromagnetic valves, and each electromagnetic valve all is connected with mold cavity respectively.
Operation principle of the present utility model is as follows: when mold cavity need be inhaled vacuum, the vavuum pump running produced vacuum, inhales the opening one-way valve, made vacuum tank produce vacuum, and electromagnetic valve gets electric and is opened, and draws the air in the mold cavity, made mold cavity produce vacuum.When maximum vacuum that the vacuum of vacuum tank is set greater than the vacuum electro connecting pressure gauge, the vacuum electro connecting pressure gauge is normally closed, and the contact will cut off the contactor in the electric cabinet, thereby vavuum pump is shut down; When the vacuum of vacuum tank was depleted to the lower limit vacuum of setting less than the vacuum electro connecting pressure gauge, the vacuum electro connecting pressure gauge was often opened, and the contactor in the electric cabinet will be connected in the contact, thereby made vavuum pump start running.
The beneficial effects of the utility model are can avoid effectively that the temperature of vavuum pump rises too high, can prolong the service life of vavuum pump, energy savings.
Below in conjunction with drawings and Examples the utility model is illustrated further.
Description of drawings
Fig. 1 is the utility model combining structure schematic diagram.
The specific embodiment
As shown in Figure 1, a kind of novel vacuum extractor of EVA foaming machine, it mainly comprises electric cabinet 1, vacuum electro connecting pressure gauge 4, vavuum pump 2, check valve 3, vacuum tank 5, six electromagnetic valves 6, six mold die cavities 7, it is characterized in that, electric cabinet 1 is connected with vavuum pump 2, the air entry of vavuum pump 2 is connected with check valve 3, check valve 3 is connected with vacuum tank 5 again, realize being connected by vacuum electro connecting pressure gauge 4 between electric cabinet 1 and the vacuum tank 5, vacuum tank 5 is connected with six electromagnetic valves 6, and each electromagnetic valve 6 all is connected with mold cavity 7 respectively.
