Ultraviolet (UV) continuous printing device for transfusion bag film material

Abstract

The invention discloses an ultraviolet (UV) continuous printing device for a transfusion bag film material. The UV continuous printing device comprises a continuous film supplying device, a corona treatment device, a UV printing device, a UV drying device and an automatic continuous film coiling device which are sequentially arranged in the film material conveying direction, wherein the continuous film supplying device is used for conveying the to-be-printed film material continuously to the subsequent devices; and the automatic continuous film coiling device is used for coiling the printed and dried film material again into film rolls. By adopting the printing device disclosed by the invention, continuous UV printing can be realized; film changing and film coiling can be realized without halt, so that full-automatic printing is realized; the UV printing technology is adopted, so that the defect of heat transfer printing is completely overcome; and particularly, the requirements of a pharmaceutical enterprise for the printing effect, the printing quality and the printing efficiency can be met.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a UV printing device for pre-printing film materials for producing medical solution packaging bags and capable of continuous printing. Background technique [0002] At present, in the pharmaceutical industry, the printing of infusion bags mainly adopts thermal transfer printing technology, including two forms: hot stamping and thermal transfer printing. Although this printing technique is widely used, it has the following disadvantages: [0003] First of all, the printing cost is high, the mold cost is high, the cooling stop time is long when the mold is replaced, the consumables need a large inventory, and the heat capacity of the mold is large, and the environmental load is large. [0004] Secondly, the printing clarity is often inconsistent, the utilization rate of the printing ribbon is very low, it is not suitable for printing extremely small characters, the char...

Problems solved by technology

[0008] This will greatly reduce the printing speed and efficiency, and can only provide high-end printing products for users with relatively small production volume. For users with large production volume, the combination of UV printing machine and large infusion soft bag line is used The machine utilization rate is low, the cost advantage is not obvious enough, and it cannot meet the requirements of modern industrialization
