Description
Technical field
The present invention relates to a kind of online printing easy-torn line technology, more particularly, it relates to a kind of cooperation pillow formula packet
The method of online laser printing easy-torn line that installation uses.
Background technology
Pillow type packaging bag with its quantitative package, take conveniently, the advantages such as quality, at low cost be widely used to food,
Key works Drug packing industry.It is open for the ease of packaging bag, the package design of many products has tearable mouth.
The production method of common tearable mouth has die pressing, offline laser method, cutter patterning method and easily tears packet currently on the market
Material.Die pressing therein and offline laser method are required to the cooperation of packaging material manufacturer and complete, and cutter patterning method is in pillow type packaging
Cutter on machine is installed, in process of production, tearable mouth is cut out respectively in the horizontal sealing of pouch and longitudinal sealing, what they were respectively present lacks
Putting is：
(1) die pressing is that easy-torn line, prefabricated cost are very high in molding in advance in the production process of composite membrane.
(2) offline laser method easily deforms leatheroid, easy-torn line is caused to pass through horizontal stroke due to there is leatheroid succeeding stretch
Occurs the problem of not easily openable during envelope.
(3) cutter patterning method is that cutter is installed on pillow type packing machine, so that in process of production, cutter acts on packaging
The horizontal sealing and longitudinal sealing of bag cut out tearable mouth respectively, and maintenance cost is high.
(4) the packaging pouch open of common packaging material is difficult, and the commercially available packaging material that easily tears is special due to being formulated, expensive,
Use cost is high.
Invention content
The purpose of the present invention is exactly to solve above-mentioned problems of the existing technology, and provide a kind of pillow type packaging thus
The method of the online laser printing easy-torn line of bag.The application of this method solves above-mentioned problems of the existing technology, and has
There is the characteristics of reducing maintenance cost, improving production efficiency and be more easy to tear.
The technical scheme is that：
A kind of method of the online laser printing easy-torn line of pillow type packaging bag, includes the following steps：
(1) the applicable packaging material of design；
(2) it determines the pouch-shaped of pillow type packaging bag and designs the position of easy-torn line；
(3) suitable Laser Jet device is selected；
(4) starting device and program complete the printing of easy-torn line：
Position is prejudged with virtual cam, make pillow type packaging bag packaging material moved under the drive of paper feeding mechanism it is specified
Trigger signal is sent out by PLC behind position, Laser Jet device receives signal and emits the surface layer of packaging material described in laser penetration, last root
The printing of easy-torn line and product batch number is completed according to the stamp parameter pre-set.
In above method：
The packaging material is aluminum-plastic composite membrane, and the aluminum-plastic composite membrane includes surface layer, middle layer and bottom, the table
Articulamentum is respectively arranged between layer and middle layer and between middle layer and bottom.
The skin-material is PET, intermediate layer material AL, primer PE2, connection layer material for PE or
HDPE。
The thickness on the surface layer is 12 μm, and the thickness of middle layer is 7~20 μm, and the thickness of bottom is 40~100 μm, connection
The thickness of layer 34 is 0~40 μm.
The Laser Jet device selects the closed CO that power is 15-100w2Laser marking system.
The Laser Jet device selects the Domino D320i Laser Jet devices that power is 30w.
With insufficient, advantage is shortcomings the present invention overcomes the prior art：
(1) due to being pre-designed suitable laser printing and there is the packaging material cooperation pillow type packing machine of high performance-price ratio to use,
Special compared to formula easily tears packaging material, not only at low cost, but also can obtain maximum efficiency.
(2) two kinds of right angle pouches of optimization design, than fillet pouch not only save packaging material, but also convenient for being beaten in line laser
Print, it is simple and convenient.
(3) without as the prior art compared to die pressing need the prefabricated easy-torn line in leatheroid production process, can be with
Directly print, it is time saving to save trouble.
(4) avoid present in the cutter patterning method of the prior art easily occur during pouch is torn pass through horizontal sealing
When the problem of being difficult to tear.
(5) printing, cut paper, packaging one-pass molding compared to offline laser method, have prevented by printing packaging material because of secondary drawing
It stretches and the problem of deformation occurs.
(6) it prints the standard configuration function of product batch number using pillow type packing machine and borrows the existing function mould of laser marker
Block can synchronously complete two tasks of lot number printing and easy-torn line printing, not only save the time-write interval, but also improve and beat
Efficiency is printed, there is good practicability.
