Description

Realize the device of automatic vacuum gas flush packaging

The utility model relates to a kind of device or equipment of realizing the automatic vacuum gas flush packaging, and Patent classificating number B65B is particularly suitable for forming the automatic vacuum gas Flushing Machine with multiple batch (-type) automatic packaging machine.

At present, in developed country and area, vacuumizing-inflating packing has been widely used in the fresh-keeping of various living delicatessens.According to reports, the general family in Taiwan preserves rice, will be subjected to insect pest in one month, and vacuum packaging can overcome going mouldy of rice, ageing and insect pest, freshness date 1-2; Indonesia's report is preserved and is reached 2-3.Therefore " vacuum rice " become the main flow commodity in rice market, Hong Kong.

China is the manual box type vacuum wrapping machine of stock production, belongs to low-and-medium-grade products, though cheap, production efficiency is low, and it is many to use of labor.No. 88106439.4 patent disclosures of China " a kind of automatic shaping packager by vacuum sucking moulding ", Anhui Tunxi Diesel Engine Plant goes into operation, high gear product in the genus, the sale situation is good.China's 90211824.2 patents are " valve formula gas Flushing Machines ", without vacuum chamber, after bulk container found time, can fill the wrapping machine of mixture gas, but not be automatic.92 years No. 92201920.7 patents " small vacuumizing-inflating packing machine ", to or made A brief introduction without the vacuum packing machine of vacuum chamber etc., no longer repeat at this.

External some very advanced automatic vacuum gas Flushing Machine or manufacturing line, but all complicated, equipment is huge, costs an arm and a leg, the large low-grade goods of incompatibility are as the packing of grain etc.Various Heat forming automatic vaccum packagers are in U.S., and day, states such as moral are early existing goes into operation.88103776.1 be Lei Ge company in Chinese patents, it is that plastic sheet is finished the hot plastic uptake of vacuum with mould and become box, is filling food subsequently, closes first inside back cover limit, lid back, the 4th limit is sealed in the inflation of finding time again.The equipment advanced person, several line concurrent jobs, the efficient height, equipment is huge." food and machinery " No.4P7 in 1992 has reported the very high TVP-B2 type rotary type vacuum wrapping machine of a kind of degree of automation of Japanese product, can reduce labor intensity greatly, although expensive, still heightens to America and Europe's outlet.

Comprehensive above-mentioned and other correlation technique, present vacuum packaging machine, price is comparatively cheap, is manual operations, and degree of automation is not high, and production efficiency is low, and is many with labour power, remains to be proposed new scheme.

The purpose of this utility model provides a kind of simple in structure, without vacuum chamber, can realize automatic vacuum air-packing devices to solid-state few dust food, form the automatic vacuum gas Flushing Machine with multiple automatic packaging machine, not only enhance productivity but also ensure the quality of products, make the automatic vacuum gas flush packaging that practical meaning be arranged.

The technical solution of the utility model comprises automatic packaging machine; The vertical thermal sealing device 4 of automatic packaging machine bag making device bag length direction and the transverse thermal sealing device 10 of bag cross direction are separated a segment distance, connect with arm plate 9; In spacing, install one interrupt 12 and can make interrupt 12 with packaging bag 2 plastic sheetings between the leak free pre-press seal device 5 of interrupting, press seal device 5 is connected with cutting knife 14 usefulness arm plates 16 in advance; The pipeline 7 of interrupting links to each other with the time scale controlling valve by the former hopper 3 and the gas ducting 1 of bleeding; The time scale controlling valve: the interface plane of the charging connector 26 of corresponding valve body 27 and the pipeline that links to each other with vacuum chamber 24,25, on the spool 23 that links to each other with dynamical axis, different air passage 31 is opened in orientation on demand; Air passage 31 links to each other with two vacuum pumps 17,19 with two vacuum chambers 18,20 respectively by pipeline 24,25, links to each other with gas filled device by charging connector 26; It is big that the vacuum chamber space ratio is taken out the packaging bag space.Overall process realizes automatic guidance.

The benefit that the utility model is compared with background technology:

1). realized the automatic vacuum gas flush packaging in a kind of new mode;

2). with time scale controlling valve simple in structure, the automatic guidance of the gas replenishment process of realizing bleeding;

3). the advantage of two vacuum pumps and two prechamber systems:

General box type vacuum wrapping machine vacuum chamber is bigger tens times to tens times than the space of bleeding of packaging bag, because the vacuum chamber constant volume, the time of bleeding relatively is long.The relative space of bleeding of the packaging bag of two vacuum pumps and dual-vacuum chamber system is little, by the venting to vacuum chamber, can improve production efficiency greatly in the be up to state standards 1.332KPa degree of vacuum standard of GB9177-88 regulation of moment.

Example of the present utility model is on the vertical DXD series automatic packaging machine basis of four banding mouths, the automatic vacuum air-packing devices of finishing, and structure is as follows:

The DXD automatic packaging machine: initiatively pivoted arm is exactly an arm plate 9 herein; Make passive pivoted arm into initiatively pivoted arm, hold-down arm plate 16; The top of machine is a weighing mechanism, is former hopper 3 (see figure 2)s under it;

Fig. 2 is the enlarged drawing in Fig. 1 left side, bag making device is the vertical thermal sealing device 4 with the bag length direction, silicon rubber pad 4a and electric heater 4b (see figure 3), separate suitable distance with bag cross direction transverse thermal sealing device 10, be associated in together with an arm plate 9, the centre interrupts 12, and transverse thermal sealing device 10 is being interrupted below 12, the length of vertical thermal sealing device 4 is greater than the long spacing separately that adds of bag, and some will seal with last one bag of 11 remaining both sides and be connected;

Among Fig. 4, interrupting 12 is hollow, and profile is the rounded flat pipeline (see figure 5) of wedge angle, and its front-end pipelines is looked the Different Package thing and can be installed dustproof and prevent the mechanism that products to be packaged enter, as filtering net 8 etc.; Its upper end pipeline 7 links to each other with the time scale controlling valve through former hopper 3 usefulness pipelines 1;

What Fig. 2 below showed is the bag tractor 13 of DXD automatic packaging machine, and it is below transverse thermal sealing device 10, and cutting knife 14 is connected with pre-press seal device 5 usefulness arm plates 16 in 10 1 bag strong points of distance transverse thermal sealing device, for other type, can make the device of synchronization action;

Fig. 2 upper right side is a time scale controlling valve (see figure 6), on the different cross section of a side of valve body 27, is welded successively: inflation chews 26, pipeline 25 and pipeline 24; Spool 23 1 ends support with the bearing 22 that is contained in the bearing seat 21; Spool 23 chews 26 in the correspondence inflation, on the Different Plane of pipeline 25,24, opens different air passages 31 (see figure 7)s; Fixed support 29 is used for support and connection and chews 30 and spool 23; Press vacuum technique, dynamic vacuum sealing can be adopted different designs, and the O-ring seals 28 among the figure on spool 23 connects seal cover cap to be chewed 30 and form the dynamic vacuum sealing systems with spool 23.

At last, link to each other with two vacuum pumps 17,19 with two vacuum chambers 18,20 respectively, link to each other with gas filled device by charging connector 26 by pipeline 24,25; It is big that the vacuum chamber space ratio is taken out the packaging bag space.

Like this, on the automatic packaging machine basis, an automatic vacuum gas Flushing Machine has just all been finished.
