Description
Technical field
The utility model belongs to package packing machine, relates to a kind of packaging bag banding shaping mechanism that is used for the packaging bag shaped device.
Background technology
In the existing automated packaging equipment, the packaging bag that is used for powder packaging often needs to form many bandings longitudinally in forming process.Common banding shaping mechanism includes flanging shaping mechanism and hot pressure composite structure, its forming process is: form the flanging of projection earlier by the flanging shaping mechanism on the plastic sheeting that passes through, pass through the hot pressure composite structure then with the bonding formation banding of flanging hot pressure.
The flanging shaping mechanism of traditional structure generally comprises punch with tabular basal plane and the die that cooperatively interacts, and in the forming process, plastic sheeting passes between punch and die, forms the flanging of projection.In the shaping mechanism of this structure, the contacting travel of plastic sheeting and shaping mechanism is long, contact area is big, so can cause shaping mechanism big to the frictional resistance of volume film, traction has increased burden to packing machine; In addition, to the requirement on machining accuracy height of shaping mechanism, and the gap between punch and the die is adjusted inconvenient.
The hot pressure composite structure of traditional structure generally is that the plastic sheeting guiding that will form flanging enters the boiling hot piece of heating, utilizes high temperature to scald this flanging of piece pressing, makes it be shaped to the banding of packaging bag.This type of traditional banding molding mode mainly has the following disadvantages: when 1, high temperature scalded piece pressing flanging, the film around the conduplication side also heated, and can cause the wrinkling or scald that flanging film on every side is unnecessary, had reduced product quality; 2, on the continous way packing machine, when machine quits work, necessarily require the boiling hot piece on the flanging in time to separate, otherwise can scald, scorch film, boiling hot piece again closes during machine operation; In like manner, just require the folding of boiling hot piece more frequent on intermittent packaging machine, this just makes and has improved equipment cost by the complex structure that scalds piece folding controlling organization.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of simple in structure, running resistance is little, requirement on machining accuracy is low, adjust and control is convenient, be difficult for scalding the packaging bag banding shaping mechanism of packaging bag film.
Packaging bag banding shaping mechanism of the present utility model includes flanging shaping mechanism and hot pressure composite structure, described flanging shaping mechanism includes a top roll and lower roll that is parallel to each other, described lower roll spaced surface is provided with annular groove, the top roll spaced surface be provided with lower roll on the corresponding annular convex rib of annular groove.
Described lower roll is made up of a lower roller shaft and a plurality of roller shells down that are enclosed within on the lower roller shaft, the outer rim of the adjacent face of two adjacent following roller shells has the breach of annular, and the relative annular breach on adjacent two following roller shell end faces has constituted above-mentioned annular groove jointly.
Described top roll is made up of a plurality of last inserted sheets of going up roller shells and several annulars that a last roll shaft and compartment of terrain are enclosed within on the roll shaft, described last inserted sheet is clamped between two adjacent last roller shells, the external diameter of last inserted sheet is greater than the external diameter of last roller shell, and the part that last inserted sheet outer ring is projected on roller shell promptly constitutes above-mentioned annular convex rib.
The described roller shell of going up all can adopt elastomeric material with following roller shell, to increase its surperficial coefficient of friction, can prevent sideslip at plastic sheeting effectively when beginning to enter upper and lower roll like this.
Described hot pressure composite structure includes heat block, and heating is installed in the heat block; Be connected with heat insulation below heat block, the heat insulation bottom has a heating tank that can supply the packaging bag flanging to pass through; Be placed with the gas outlet on the sidewall of heating tank, have air inlet on the heat block, the passage of air inlet process heat block and heat insulation inside communicates with the gas outlet on the heat insulation; The port of export at heating tank is arranged side by side a pair of pressured cylindrical roller mutually, and the flanging that passes from heating tank can be from passing between the binding face of two rollers and being formed banding by the roller pressing.
The heat block of described hot pressure composite structure can be arranged side by side a plurality of, and each heat block below all is connected with one group of heat insulation and roller.
In the described hot pressure composite structure, also can below an integrally-built heat block, be arranged side by side many group heat insulations and roller.
Flanging shaping mechanism of the present utility model adopts the cylindrical upper and lower roll that has groove and convex tendon to replace the punch and the die of traditional structure middle plateform shape, in the plastic sheeting running, be rolling friction like this between film and the upper and lower roll, its frictional resistance is the long-pending sliding friction of large contact surface between plastic sheeting and protruding, the die in the traditional structure running, thereby has alleviated the burden of packaging film feeding mechanism; In addition, can come gap between control loop connected in star and the annular convex rib by the spacing of regulating upper and lower roll, and by at the width of the mode adjustable ring connected in star that pad is set between the roller shell down to adapt to the instructions for use of different size packaging material, it is easy to adjust, and is also lower to the required precision of parts.Hot pressure composite structure of the present utility model adopts the hot-air that blows out that the flanging on the packaging bag film is heated, and will heat with press seal and finish step by step, can control heating process by the break-make of thermal current, saved boiling hot piece and controlling organization thereof complicated in the traditional structure, thus simple in structure, control is convenient and reliable; In addition, the packaging bag film is to pass through from the heat insulation surface in its course of work, thereby can not scald the film beyond the flanging, has improved the quality of packaging bag.
