Abstract

The utility model relates to a device, which pumps air or charges air into various plastic bags with different thickness. In addition, after pumping or air charge is completed, the plastic bags are rapidly sealed. The device comprises an air nozzle; an air hole of the air nozzle is connected with an air pipe connected with a negative end of an electromagnetic valve. The other end of the electromagnetic valve is connected with a tee joint, and other two ends of the tee joint are connected with two diaphragm pumps. A leather bowl of the pump causes a valve plate to be fanned in a pump body by the reciprocating extrusion of an electromagnetic drive mechanism. Two mould cavities in the pump generate air difference, which reaches the purpose of pumping or air charge. In practical production, multi-function vacuum packaging machines of ST-6688 (1) type and ST-6688 (2) type are produced. The product has the advantages of compact structure, high degree of vacuum, high pumping speed, convenient operation and low cost, and the utility model is suitable for protecting family articles and preserving food, etc.

Description

Multifunction vacuum packager

The utility model is a kind of family daily life articles for use, refer to especially a kind ofly in various different-thickness plastic bags, bleed by (I type) or bleed/inflate (II type), and finish bleed or inflate after give the device of this plastic bag sealing rapidly.

Fresh-keeping for living delicatessen; Food, Chinese and Western medicine, cigarette tea, calligraphy and painting, ancient books, Valued Securities, film, tape (dish), the first-class moistureproof and mildewproof of optical frames; Disinfecting apparatus anti-pollution; Medicinal material, dry fruit, grain etc. anti-damages by worms and jewellery, gold and silver ware, souvenir and precision metallic parts antirust etc., and simple and effective measure is exactly a Vacuum Package.

In the past have bleeding, all cost is higher to fill the sealed in unit of atmosphere gas and enclosing function, and volume and power consumption are bigger, are unsuitable for general family and use.

The purpose of this utility model is to provide a kind of having of being fit to that general family uses to bleed or the vacuum package device of inflation and enclosing function.

Described vacuum package device comprises a valve, and the pore of valve connects a tracheae, and tracheae connects the negative terminal of electromagnetic valve, and the other end of described electromagnetic valve connects a threeway by another tracheae, two diaphragm type pumps of other two terminations of this threeway; This packaging machine also comprises a pump valve sheet of agitating by the pump cup of electromagnetic drive mechanism reciprocating extrusion and because of pressure reduction; Described packaging machine is with a non-contact switch circuit, an exhausr port.Described packaging machine comprises two by the heating wire of heat seal transformer-supplied and control the adjustable non-contact switch circuit that seals the time of described heat seal voltage transformer.This packaging machine comprises that is also filled a nitrogen mouth.Described vacuum package device comprises upper-cover, adjusts the device of heat-sealing time, sells button, depression bar, switch pump, the change-over swith of bleeding/inflate, heat seal key and seals indicator lamp.

Keystone configuration of the present utility model is switch circuit and the quick electromechanical interlocks that has adopted diaphragm micropump formula pump, contact pointless to control, and promptly valve is promptly connected the heat seal transformer frequency response after withdrawing from plastic bag, cuts off the electromagnetic driver power supply simultaneously.

Further narrate the utility model below in conjunction with accompanying drawing with example.Wherein,

Fig. 1 opens birds-eye view behind the loam cake for the utility model.

Fig. 2 is an outside drawing of the present utility model.

Fig. 3 is a back view of the present utility model.

Fig. 4 is a non-contact switch circuit schematic diagram of the present utility model.

Fig. 5 is a pump housing assembly drowing of the present utility model.

Fig. 6-1 and Fig. 6-2 is the front view and the lateral plan of depression bar of the present utility model.

Fig. 7-1 and Fig. 7-2 is the front view and the lateral plan of heat seal voltage transformer.

Fig. 7-3 is heat seal transformer lines figure.

Principal organ of the present utility model and functional element figure have been marked among Fig. 1.Marked among Fig. 3 and filled nitrogen mouth (10) and exhausr port (11), bonnet (12) can draw back and take off, and is convenient to clean or change filter (13), and exhausr port will be strictly on guard against obstruction.Rubber cap (14) will be locked when restoring, and influences work otherwise can leak gas.In the non-contact switch circuit schematic diagram from Fig. 4 as can be seen, it adopts 220 volts/50 hertz power supply, by micro-switch control heat seal voltage transformer and pump actuator, the heat-sealing time is adjustable in second at 3-15, have noiseless, no spark, long characteristics of life-span, adopt two parallels connection of pumps among Fig. 5, bleed stable and pumping speed fast, degree of vacuum can be up to 0.035MPa.The mechanism design of depression bar has multi-functional among Fig. 6: 1, make the automatic retraction of valve.2, termination of pumping, heat-sealing translation function.3, compress the plastics sack, make heat-sealing reliable.Heat seal voltage transformer among Fig. 7 has the core section of 7.8 sq cms, and horsepower output is up to 70 watts.

After principle of work of the present utility model is achieved in that and opens upper-cover (1), according to plastic bag thickness adjustment heat-sealing time device (6), with pulling outlet nozzle (8), be equipped with need packaged articles plastic bag cover on valve, and flattening sack.Cover upper-cover, pin button (7) is pinning automatically, depression bar this moment (3) is with power connection, press switch pump (4), alternating current forms alternating magnetic field by permanent magnet, produces push-pull effort, drive leather cup (Fig. 5) reciprocating extrusion, change mold cavity volume in the pump housing, produce draught head drive pump valve sheet and agitate, the gas in the plastic bag is extracted out by the tracheae that links to each other with valve.After reaching requirement when bleeding, charge into atmosphere gas as need, the change-over swith (2) that only needs will bleed/inflate is pulled to inflation one side, and this moment, the electromagnetic valve startup was promptly inflated in bag.

Bleed/inflate finish after, both hands are pressed heat seal strong (9), this moment, the top pin at depression bar middle part was return valve, the little top nail of depression bar one side touches micro-switch simultaneously, and pump promptly quits work, and starts heat seal voltage transformer (Fig. 7), it is bright to seal indicator lamp (5), after reaching the heat seal setting-up time, indicator lamp goes out, and heat-sealing is finished.Open upper-cover, take out the plastic bag of sealing, check seal quality.

The utility model is because adopted miniature film chip pump, the on-off circuit of contactless control and quick electromechanical interlocks, with existing vacuum packaging equipment relatively, compact conformation, volume is little, vacuum is high (can reach 0.035MPa) and pumping speed is fast, easy to operate; In addition, because other part material of great majority is ABS, so cost is low, use so be fit to general family.
