Description

Technical Field

[0001] The utility model relates to the technical field of paper-plastic bag printing and drying, in particular to a printing paper drying device for paper-plastic bag processing. Background Art

[0002] Medical paper-plastic bags are a commonly used packaging material in the medical field. They combine the characteristics of paper and plastic and play an important role. Their main features include: Paper part: Made of medical dialysis paper, it has good air permeability, allowing the sterilizing agent to penetrate smoothly to achieve effective sterilization. The paper surface is flat and the printing is clear, facilitating the identification and recording of relevant medical product information. Plastic part: Usually a transparent plastic film, it provides good visibility for easy viewing of the internal items. It has excellent barrier properties, effectively preventing the intrusion of moisture, microorganisms, etc.

[0003] Currently, when printing paper-plastic bags, first, the rolled paper-plastic bags are placed on the conveying rack, and then one end of them is passed through the printing machine. When one end comes out of the printing machine, at this time, it is then passed into the drying machine to dry the ink on its surface. The dried paper-plastic bags pass through the drying machine and are connected to the external winding roller, and then are wound by the winding machine for convenient subsequent processing;

[0004] Since, after the above-mentioned paper-plastic bags are printed, generally a dryer or an air-cooling machine is used to quickly dry them. If a dryer is used, although the high temperature in the dryer can accelerate the drying speed of the ink on the surface of the paper-plastic bag, however, the dried ink does not have good adhesion and gloss, and at the same time, it is easy to produce ink spots and bubbles, thus reducing the aesthetics of the product. If air-cooling is used for drying, although the drying of the ink is also achieved, the drying speed is slower compared to high-temperature drying, so the printing speed and the overall production efficiency are reduced.

[0040] Embodiment III

[0041] As Figures 1 - 6 shown, on the basis of the above embodiment, the following content is further given in this embodiment:

[0042] The conveying assembly 5 includes a first conveying roller 51, a second conveying roller 52, a third conveying roller 53, a first auxiliary roller 54 and a second auxiliary roller 55. The inner cavity of the processing box 2 is respectively rotatably connected with a first conveying roller 51, a second conveying roller 52 and a third conveying roller 53.

On the other hand, it can also partially isolate the air-cooling drying and the heating drying, reducing the mutual influence.

[0044] The working principle and usage process of the present utility model:

[0045] In the state of use:

[0046] During use, first, place the rolled paper-plastic bag on the conveyor 8. Then, insert one end of the paper-plastic bag into one end of the processing box 2. After insertion, at this time, pass through the two groups of limiting rollers 35. After passing through, then pass through between the printing roller 44 and the driving roller 48. After passing through, then pass through between the first conveying roller 51 and the first auxiliary roller 54. After passing through, at this time, pass above the second conveying roller 52. After passing through, at this time, pass through between the third conveying roller 53 and the second auxiliary roller 55. After passing through, pass out of the processing box 2 and connect and fix it to the winding roller on the winding frame 9;

[0047] At this time, rotate the opposing threaded rod 33. When the opposing threaded rod 33 rotates, it will drive the two groups of opposing blocks 34 to move towards each other. When the two groups of opposing blocks 34 move towards each other, they will drive the two groups of limiting rollers 35 to move towards each other, thus realizing the limiting of both sides of the paper-plastic bag;

[0048] After limiting, at this time, start the printing motor 42 and the driving motor 46. When the printing motor 42 works, it will drive the printing roller 44 and the adhesive roller 45 to rotate respectively. When the adhesive roller 45 rotates, the ink in the hopper 41 can be adsorbed on its upper part. At this time, when the adhesive roller 45 with ink moves to the scraper 43, then the excess ink on the surface of the adhesive roller 45 is cleaned by the scraper 43. After cleaning, the surface of the adhesive roller 45 comes into contact with the surface of the printing roller 48. After contact, the ink can be adhered to the printing roller 48. At this time, the work of the driving motor 46 will also drive the rotation of the driving roller 48. When the driving roller 48 rotates, under the action of the printing roller 44, on the one hand, the transportation of the paper-plastic bag is realized, and on the other hand, the printing of the paper-plastic bag is realized;

[0049] When the printed paper-plastic bag enters the first conveying roller 51, at this time, start the cooling fan 64. When the cooling fan 64 works, it starts to cool the printed paper-plastic bag and also preliminarily dries the ink. When it is preliminarily dried, at this time, the preliminarily dried paper-plastic bag moves to the third conveying roller 53. At this time, by starting the heating wire 76 and the air supply fan 75, when the heating wire 76 works, it heats the air, and when the air supply fan 75 works, the heated air can be transported to the paper-plastic bag to heat the paper-plastic bag and the ink, so that the ink is dried. The dried paper-plastic bag will move to the winding frame 9 for collection.
