Description

Technical Field

[0001] The utility model belongs to the field of plastic pipes, and particularly relates to a device for quickly removing UV-curable ink jet codes from PO pipes. Background Art

[0002] PO pipes, namely polyolefin pipes, are a common type of plastic pipes. Due to their excellent properties such as good abrasion resistance, impact resistance, and corrosion resistance, they are widely used in fields such as construction, municipal engineering, petrochemical industry, etc. According to regulations, PO pipes must be marked during production. Traditionally, ordinary ink is used for jet printing. After such pipes are crushed, they can be directly recycled without affecting the product quality.

[0003] However, in recent years, in order to prevent products from being counterfeited, distinguish them from competing products, and pursue more beautiful jet printing and a more upscale appearance of the products, a two-color jet printing method is adopted. The two-color jet printing uses UV-curable ink, which crosslinks and cures on the surface of the pipe under the action of ultraviolet light. Its jet printing fastness is good and the color is bright. Due to the insoluble and infusible characteristics of the crosslinked and cured material, green insoluble lumps, black spots, or local hue differences (biased towards the green hue) will appear during the crushing and recycling process of defective products. It has been verified that hue changes and obvious impurities occur during the recycling process of such crushed materials in PO pipes, taking PPR pipes as an example.

[0004] In order to eliminate the influence generated during the recycling process, the traditional method is to manually use a blade for removal, which not only has a large labor intensity and low efficiency, but also has problems such as uneven scraping. Content of the Utility Model
