Description

PTP aluminum foil printing coating device

Technical Field

The invention belongs to the field of printing, and particularly relates to a PTP aluminum foil printing and coating device.

Background

PTP aluminum foil is an aluminum foil used for medicine packaging, when an aluminum foil packaging bag is manufactured, the processes of material feeding, adhesive coating, drying, compounding, printing, rolling and the like are carried out, wherein the compounding process is to coat the adhesive on the aluminum foil and then compound a layer of PVC hard sheet on the surface of the aluminum foil, but in the prior art, when the adhesive is coated, the coating amount of the adhesive is difficult to control, if the coating amount is small, the adhesiveness is poor, if the coating amount is large, the waste of the adhesive is caused, and when the aluminum foil is compounded, the adhesive overflows from the side edge, the aluminum foil needs to be cleaned firstly, and then the next link is carried out, so that the processing procedure is increased, and the production efficiency is influenced.

Disclosure of Invention

The invention aims to provide a PTP aluminum foil printing and coating device, which solves the problem that the glue yield of an adhesive in the prior art is not easy to control.

The basic scheme of the invention is as follows: the utility model provides a PTP aluminium foil printing coating apparatus, includes the frame, is equipped with blowing unit, rubberizing mechanism, stoving mechanism, compound unit, printing mechanism and receipts material unit in the frame in proper order, rubberizing mechanism has the piston board and goes out the offset plate including the box that is hollow structure, and sliding connection has the piston board in the box, and the adhesive is located the piston board and is gone out between the offset plate, is equipped with a plurality of glue outlet holes on going out the offset plate, is equipped with the shrink mouth structure that the pressurized warp on going out the glue outlet hole, when not working, the shrink mouth structure is in the encapsulated situation, and piston board and play offset plate form airtight cavity with the box, the piston board is connected with and is used for driving its gliding power pack from top to bottom in.

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

1. the piston plate and the glue outlet plate are arranged to slide in the box body in a sealed mode, the glue outlet hole of the glue outlet plate is further provided with a rubber ring, a sealed cavity can be formed between the two plates, when the piston plate is driven by the power unit to slide downwards, the pressure in the cavity between the two plates is increased, the glue outlet plate can slide downwards under the influence of the pressure until contacting with an aluminum foil, due to the fact that the thicknesses of the aluminum foils are different, the aluminum foils with different thicknesses can be met, meanwhile, the adhesive can also be influenced by the pressure, the original sealed contraction opening structure is squeezed open, the adhesive is smeared on the aluminum foil, and due to the fact that the pressure in the same sealed cavity is balanced and fixed, the force of the pressure squeezing contraction opening is the same, the glue outlet quantity and the glue outlet speed can be kept the same, and the glue outlet quantity can be well controlled.

2. The blowing unit, rubberizing mechanism, stoving mechanism, compound unit, printing mechanism and the unit of receiving that are equipped with in the frame realize automatic assembly line processing to the aluminium foil, therefore the aluminium foil constantly conveys under a offset plate, but because a offset plate can contact with the aluminium foil under the effect of piston board, so when the aluminium foil received the conveying, the adhesive on the aluminium foil has just also been smeared by a offset plate.

Further, the piston plate is further connected with a driving rod, the printing mechanism comprises an ink box, a stirring unit is arranged in the ink box, a connecting rod is connected to the stirring unit, and the connecting rod is fixedly connected with the driving rod.

Because the present printing aluminum foil generally uses the special ink of the aluminum foil which takes vinyl chloride, vinyl acetate copolymer resin and acrylic resin as main components, although the adhesion with the aluminum foil is very strong, the solvent volatility of the ink is large, the drying of the ink is easy to occur, and the condition of pasting the plate is caused, when the power unit drives the piston plate to move upwards, the driving rod connected with the piston plate drives the connecting rod to move upwards together, so that the stirring unit connected with the connecting rod also moves upwards, therefore, when the power unit drives the piston plate to slide up and down in a reciprocating manner, the stirring unit can be driven to move up and down in the ink tank, the ink in the ink tank is stirred, and the drying of the ink is prevented.

Furthermore, the oven is also communicated with a second pipeline, and the second pipeline is communicated with the ink box.

A part of hot air after heating in the oven can be diffused into the second pipeline, and the second pipeline transfers the hot air into the ink box to heat the ink box, so that the condition of preventing the ink from being condensed can be achieved.

Further, a one-way valve for preventing ink in the ink tank from escaping is arranged on the second pipeline.

The one-way valve is provided in the second conduit to prevent ink from escaping with the air as the piston plate moves downwardly, which draws air from the ink tank as the piston plate moves downwardly.

Further, printing mechanism still includes the ink roller of going out that is equipped with in the china ink case, goes out the china ink roller below and is equipped with the printing roller, the printing roller with go out the contact of china ink roller.

And the ink outlet roller transfers the ink in the ink box to the printing roller, and the printing roller completes the printing of the aluminum foil.

Further, a spring is connected between the piston plate and the rubber plate.

The spring between the piston plate and the rubber plate is arranged, and the rubber plate can slide up and down more easily under the driving of the spring.

Further, the stirring unit is a stirring fan blade.

Set up stirring fan blade and stir printing ink, when second wedge pole drove stirring fan blade and reciprocated, printing ink can form the swirl in the china ink case, and stirring fan blade receives the influence of swirl, and self just can rotate, also can stir printing ink.
