Abstract

The utility model relates to a vacuum nitrogen gas filling package machine, composed of an air compressor, a nitrogen gas holder, a control box and a sealed box, wherein, the air compressor fills the sealed box with air by the control box; the nitrogen gas holder fills a packaging bag with nitrogen gas by a gas nozzle. The utility model decrease the volume of nitrogen gas and the nitrogen-making device, and saves nitrogen gas.

Description

Vacuum ammonia filled package machine

A kind of vacuum nitrogen filling packing machine belongs to the equipment that packaging bag is carried out nitrogen-filled packaging.

At present, domestic some box type vacuum nitrogen filling packing machine at first is evacuated the atmosphere in the seal casing at work, just can make the packaging bag in the seal casing form vacuum, subsequently to inflated with nitrogen in the seal casing, to the packaging bag inflated with nitrogen, seals at last simultaneously again.Because the volume ratio of seal casing and packaging bag is very big, promptly row's capacity of seal casing is very big, and the displacement gas loss is also very big, nitrogen in the seal casing can not make full use of, and causes very big waste, in addition, therefore the equipment of making nitrogen also made very greatly, makes that this wrapping machine is bulky, and cost is also very high.

The purpose of this utility model is to provide a kind of light-duty multifunctional wrapping machine, to overcome the deficiencies in the prior art.

Below principle of the present utility model and structure are described:

There is the equipment of making nitrogen the utility model inside, and it utilizes transformation absorption or hollow fiber membranes principle separation of nitrogen from air, only is used to charge into packaging bag.

In Fig. 1, need during packing whole vacuum chamber is vacuumized, fill little air again, packaging bag is compressed, and during inflation, nitrogen charges into packaging bag by valve, inflation simultaneously makes the packaging bag external and internal pressure be in state of equilibrium like this, fill nitrogen and finish, push away, charge on the heat seal device, packaging bag enclosing, outage then, connect valve, the packer's bay leads to atmosphere, and top cover is opened.

Valve is movably among Fig. 2, and the heat-sealing bar has sealing function concurrently, and air admission gasbag 19 during operation promotes heat-sealing bar press-through pack bag 21 and valve inflated with nitrogen again, and air admission cylinder 20 promotes valve 17 again and withdraws from heat-sealing bar 18, and the heat seal sealing finishes.

When packing not to be stowed under heavy cargo article, sometimes for power saving with improve package speed, this machine can with valve (valve A, B all can) directly to packaging bag vacuumize, inflated with nitrogen, when working under this operating mode, need be opened electromagnetic valve 27, valve 26 cuts out (see figure 7).

Fig. 1 is the wrapping machine structural front view

It by air compressor (1), framework (2), nitrogen gas tank (dotted portion) (3), produce nitrogen absorption canister (4), control box (5), body skin (6), heat-sealing with air bag (7), sealing with air bag (8), A type valve (9), sealing band (10), seal bar (11), top cover (12), seal case (13), find time and induction tract joint (14), vacuum pump (15).

Fig. 1 is the utility model constructional drawing.Air compressor connects control box (5), an end that connects seal casing (13) by pipe joint (14), the seal casing other end has sealing band (10) and heat-sealing bar (11), the seal casing top is top cover (12), nitrogen gas tank (3) connects valve (9) by control box (5), vacuum pump (15) is positioned at the lower end of seal casing (13), and its pipeline connects valve (9) by control box (5).

When Fig. 2, Fig. 3 chew form for using Type B gas, seal case part front view and birds-eye view.

Wherein, heat-sealing usefulness gas (7), sealing usefulness gas (8), A type valve (9), sealing band (10), the heat-sealing bar (11) in removable flexible pipe (16), valve and support body (17), heat-sealing bar (18), air bag (19), cylinder (20), the alternate figures 1.

Fig. 5, Type B valve theory structure sketch.

Fig. 6, system nitrogen part A is to partial view.

Fig. 7, the pipeline connection diagram of wrapping machine major part.

Wherein, air compressor (1), system nitrogen part (22), nitrogen basin (3), electromagnetic valve (23), adjusting flow valve (24), electromagnetic valve (25), electromagnetic valve (26), valve (9), heat-sealing bar (28), top cover (12), seal case (13), vacuum pump (15).

The utility model can directly carry out inflated with nitrogen to packaging bag, fills air in the seal casing to replace inflated with nitrogen, can save a large amount of nitrogen, reduces the volume of nitrogen-making device, cost-cutting.

Claims

A kind of vacuum nitrogen filling packing machine, form by air compressor, nitrogen gas tank, control box 5 and seal casing 13, it is characterized in that air compressor connects control box 5, and connect an end of seal casings by pipe joint 14, the other end of seal casing has sealing band 10 and heat-sealing bar 11, the seal casing top is a top cover 12, and nitrogen hold tank 3 connects valve 9 by control box 5.
