Description

Compound processingequipment of kraft paper wrapping bag

Technical Field

The invention belongs to the field of packaging bag processing, and particularly relates to a composite processing device for kraft packaging bags.

Background

Kraft paper is tough and water-resistant packaging paper, is brownish yellow, has a wide application range, is commonly used for manufacturing packaging bags, and is generally used for manufacturing packaging bags.

At present, the craft of dust removal, corona and compound is needed to make the kraft paper compound bag, the compound craft is to use the extruder of the film to extrude the film to the kraft paper, then use the compound roller to compound the film and the kraft paper. However, when the packing bags are made of kraft paper, the shapes of the packing bags are different, the required size of the kraft paper is different, when the materials are extruded by the extruder, the propelling amount of the screw rod needs to be repeatedly adjusted according to the size of the kraft paper every time, otherwise, the yield of the composite paper is not high, the extrusion amount of the extruder is adjusted for many times, and the processing efficiency is seriously influenced.

Disclosure of Invention

The invention aims to provide a composite processing device for kraft paper packaging bags, which aims to solve the problem that the extrusion capacity of an extruder is not easy to adjust according to the size of kraft paper in the prior art.

The basic scheme of the invention is as follows: composite processing device of kraft paper wrapping bag, including the frame, be equipped with blowing unit, dust removal mechanism, corona treatment machine, extrusion mechanism, combined mechanism and receipts material unit in the frame in proper order, dust removal mechanism includes the dust removal case, and the dust removal incasement is equipped with negative-pressure air fan, and negative-pressure air fan is connected with first pipeline, and first pipe connection extrusion mechanism, extrusion mechanism include the workbin, from left to right are equipped with air intake zone, material pushing zone in proper order and are used for extruding the ration material district of film in the workbin, first pipeline and air intake zone intercommunication, material pushing zone includes the piston plate of vertical sliding connection in the workbin to and the material in the workbin.

The principle and the advantages of the invention are as follows:

1. the negative pressure fan is arranged in a dust removing box of the dust removing mechanism and is used for carrying out dust collection treatment on dust on the surface of kraft paper, adsorbed air carries the dust to enter a first pipeline and then enters an air inlet area in the material box from the first pipeline, and the air continuously enters the air inlet area, so that the pressure in the air inlet area is gradually increased until a piston plate in a material pushing area is pushed to slide, the piston plate pushes the material to a material fixing area, and the material fixing area extrudes the material.

2. Compared with the prior art, when the kraft paper is subjected to dust removal treatment by using the negative pressure fan, air and dust are transmitted into the air inlet area through the first pipeline, the piston plate is pushed by using gradually increased pressure, so that the material is pushed to the sizing area by the piston plate to realize the extrusion of the thin film.

Further, be equipped with first ooff valve on the first pipeline, the district of admitting air still communicates there is the second pipeline, and the second pipeline intercommunication has the collection mechanism of dust, and collection mechanism includes the collecting box, is equipped with actuating mechanism in the collecting box, actuating mechanism with the piston plate is connected.

The collecting box of the collecting mechanism is internally provided with a driving mechanism, when the driving mechanism generates power, the driving mechanism can drive the piston plate to slide in the material box, and the piston plate can extrude the air in the air inlet area into the collecting box through the second pipeline, so that the air in the air feeding area is emptied, and the negative pressure fan can conveniently feed air into the air feeding area again.

Further, a filter screen for filtering dust is further arranged in the collection box, the collection box is communicated with a third pipeline, the third pipeline is communicated with the compound mechanism, and refrigeration equipment is arranged in the third pipeline.

The filter screen in the collecting box keeps apart dust and air, the clean air who passes the filter screen gets into in the third pipeline, refrigeration plant in the third pipeline is with air cooling, cold air gets into the combined mechanism from the third pipeline again, when compound roller compounds kraft paper and film, because the film temperature of extruding is too high, need cool off the design at once, otherwise film deformation or fold appear easily, influence the yield, the cold air that gets into in the combined mechanism can be when combined mechanism compounds the kraft paper, cool down the combined mechanism, make combined mechanism can also cool down the film when compound to the film.

Further, the compound mechanism includes a pair of hollow compound roller, and compound roller is interior roller and the outer roller of metal that the clearance fit is in the same place, third pipeline and interior roller intercommunication, and interior roller is inclosed hollow cylinder, is equipped with the refrigeration source in the interior roller.

When the compound roller compounds the kraft paper, utilize the fine temperature conductivity nature of metal, can transmit the cold air that the refrigeration source in the interior roller produced for outer roller, make outer roller temperature reduction, go up the cold air of output in the third pipeline in the cooperation again to reinforcing refrigeration effect.

Further, the refrigeration source is ice.

Set up the refrigeration source into ice, ice is heated in interior roller and melts the back, can absorb the heat that comes from outer roller to the compound roller cooling of metal, and the ice that melts can also receive the cold air influence that the third pipeline produced, condenses once more, thereby reuse.

Further, the inner roller is a rubber product.

Set up to rubber products with interior roller, rubber itself has fine elasticity, after the water that melts becomes ice, the roller in can expanding of the bloated volume of ice, make interior roller and outer roller laminating, it is faster to make outer roller cooling, and after ice melts into water, interior roller does not receive the extrusion, the shape recovers, leave the clearance between roller and the outer roller in making, the cooling rate of outer roller slows down, with this cooling rate of balancing outer roller, when making the kraft paper can obtain the cooling design, do not influence the complex of kraft paper again.

Further, a second switch valve is arranged on the second pipeline.

And a second switch valve on the second pipeline ensures that when the first pipeline ventilates the air inlet area, air cannot escape from the second pipeline, so that the pressure in the air inlet area is fixed.

Further, a screw extrusion rod and an extrusion die head are arranged in the material fixing area; still be equipped with the play flitch that is used for screw rod extrusion pole and extrusion die head feed, go out the vertical connection of flitch and be equipped with a plurality of discharge gates on the flitch in the workbin, all be equipped with the shrink mouth structure in the discharge gate.

After the piston plate pushes the material to the discharge plate, the material is extruded to open a contraction opening structure on the discharge opening, the material is drilled out from the discharge opening, the screw extrusion rod and the extrusion die head are fed, and the material is extruded by the screw extrusion rod and the extrusion die head.
