The method sequentially includes the steps of a bag forming process, a vertical sealing process and a transversal sealing process, wherein the bag forming process includes folding an entire roll of packaging film into square film bags through a bag forming unit, the transversal sealing process includes performing corner inserting and heat-sealing to the front ends of the square fill bags filled with food after being vertically sealed, by a knife-sealing corner-inserting unit, cutting the rear ends of the square film bags in advance, then performing corner inserting and heat-sealing to obtain the finished products. During the transversal sealing process, the vertically sealed square film bags can be successively subjected to end corner inserting and sealing by adopting the knife-sealing corner-inserting unit, and thereby the efficiency of forming and sealing of a whole package is improved and the sealing effect is better.
Description
Technical field
The present invention relates to a kind of method for packaging food, more particularly to a kind of packaging for foodstuff shaping mouth-sealing method.
Background technology
With the continuous progressive and development of technology, the food for circulating on the market is much all packaged into bag, wraps by packing machine
Dressing up the food of bag has many benefits.It is mainly reflected in three aspects：Packaged food is convenient to circulate；Some packagings are Food circulations
Container.Such as bottled drinks, beverage, sense tinning head, the milk powder of field dress, bottle, tank and the bag that these are packed are both packing container.
It is also the shifting tool of Food circulation and sale.It brings great convenience to Food circulation.The guarantor of protection food and extension food
Deposit the phase；The presentation quality of food is protected to produce certain economic benefit, food, be by carrying, filling in the whole process of circulation
Unload, transport and store, easily cause the damage of food appearance quality, food is by after inside and outside packaging, just can well protect food
Product, in order to avoid cause to damage；Protect food original quality, extend food storage life, food in the whole process of circulation, it
Quality can change and degenerate.Food has certain nutritional ingredient and moisture in itself, and this is the production such as bacterium, mould, yeast
The primary condition of breeding, when the temperature of food preservation is adapted to them breeds, just causes food apoilage.If food is used
Aseptic packaging or packaging after carry out high temperature sterilization, refrigeration etc. process, will prevent food spoilage phenomenon generation, extend food
Storage life.Meanwhile, food has certain moisture in itself, when the content of these moisture changes, can all cause food
The change of local flavor degenerates.If preventing from the generation of above-mentioned phenomenon using corresponding Water Vapour Proof Packaging Technique, also effectively prolong
The storage life of food is grown.Further, food is in circulation, by daylight and light direct irradiation when, and in high temperature, all easily
Aoxidize food.Change colour, the phenomenon such as spoiled is wrapped such as using corresponding vacuum packaging, gas flush packaging technology and accordingly
Package material.Equally also can effectively extend the storage life of packaged food.Promote the reasonability of Food circulation and planned；Some lifes
Fresh food, it is easily putrid and deteriorated, it is difficult distal edge and transports, such as fruit and aquatic products, various cans are at source made, just can reduce wave
Take, reduce cost of transportation, and the reasonability of Food circulation and planned can be promoted.With the continuous progressive and hair of industrial technology
Exhibition, the foods packing machine application that extensive, efficient packaging is carried out to food is also more and more extensive.Foods packing machine presses Product Status
Liquid, bulk, bulk solid packing machine can be divided into；It is divided into interior bag, outsourcing packing machine by packaging effect；Can be divided into list by multiple package position
Station, multistation packing machine；Can be divided into semi-automatic, device of full automatic packaging etc. by automaticity.
In the prior art, packing machine is packed to food, and one of them important link is to packaged product
Sealed, the quality of sealing directly affects the resting period of product, additionally, good sealing can also improve U.S. of packaging product
Sight degree.
Publication No. CN 201296388, publication date is that the Chinese patent literature of on 08 26th, 2009 discloses a kind of food
Product packing machine, including frame, are provided with the mandrel for placing packaging film in frame, and at least one is used to guide packaging
The leading axle of film trend；Feed hopper is installed with the top of frame, the bottom of feed hopper is communicated with makes packaging film form packaging bag
Collar-returning type hollow molding device, be provided with by the fortune hymeniderm band of Serve Motor Control in the vicinity of collar-returning type hollow molding device, and
Longitudinal sealer of longitudinal sealing is carried out to packaging bag, be provided with below collar-returning type hollow molding device carries out horizontal stroke to packaging bag
To the across seal device of sealing, longitudinal sealer, across seal device are all controlled by rack-mounted cylinder.The patent document
In disclosed foods packing machine, when being packed to food, its collar-returning type hollow molding device first folds to be formed not to packaging film
There is the packaging bag of sealing, through longitudinal sealer carry out longitudinal sealing again, then bottom is carried out to the packaging bag after longitudinal sealing through across seal device
Horizontal sealing, load after food carries out top horizontal sealing by across seal device again, its collar-returning type hollow molding device and longitudinal sealer and
Coordinate between across seal device and require strictly, to pack food using the foods packing machine, be entirely molded in packaging process
Seal complex, it is necessary to successively carry out horizontal sealing twice, cause whole shaping sealing less efficient, and sealing effect is bad.
The content of the invention
Defect in order to overcome above-mentioned prior art of the invention, there is provided a kind of packaging for foodstuff is molded mouth-sealing method, the present invention
During horizontal sealing, successional end face limb, sealing can be carried out to the square bag after longitudinal sealing using knife envelope limb part, made
Whole packaging shaping sealing efficiency is greatly improved, and sealing effect is more preferable.
The present invention is achieved through the following technical solutions：
A kind of packaging for foodstuff is molded mouth-sealing method, successively including into bag step, longitudinal sealing step and horizontal sealing step, its feature exists
In：Described is that entire volume packaging film is folded into quadrangular membrane bag by into bag portion part into bag step；The horizontal sealing step is by knife
The quadrangular membrane for being loaded with material bag front end after limb part is sealed to longitudinal sealing carries out end face limb and seals, after square shaped film bag
End cuts off in advance, then limb and heat-sealing as finished product.
The longitudinal sealing step is that the quadrangular membrane bag that will be loaded with material by middle envelope sealing part carries out middle sealing.
Film bag supplying step is additionally provided between the longitudinal sealing step and horizontal sealing step, film bag supplying step is by film bag
