Acoustic magnetic or radio frequency anti-theft hard tag, hard tag shell and preparation method of hard tag shell

Abstract

The invention discloses an acoustic magnetic or radio frequency anti-theft hard tag, a hard tag shell and a preparation method of the hard tag shell. The acoustic-magnetic or radio-frequency anti-theft hard tag shell is made of 100% of waste ABS plastic or made of waste ABS plastic and modified materials; a cavity structure formed by an upper shell and a lower shell is utilized, so the anti-theft hard tag shell has very good impact strength; plastic fracture and incomplete brittle direct fracture are shown even if the anti-theft hard tag shell is continuously hit by a hammer with a weight of 1 kg or 10 kg until the anti-theft hard tag shell is cracked, so the anti-theft requirement can be met; and the waste is turned into wealth, and the urgent requirement of a large number of customers for the acoustic magnetic or radio frequency anti-theft hard tag with the green tendency is met.

Description

technical field [0001] The invention belongs to the technical field of anti-theft hard tags, and relates to an acoustomagnetic or radio frequency anti-theft hard tag, a hard tag casing and a preparation method thereof. Background technique [0002] Acoustic-magnetic (AM) / radio frequency (RF) anti-theft hard tags (referred to as "hard tags" or "hard tags") usually include upper and lower shells made of ABS plastic injection molding, and pin lock cylinders and alarm components are installed in the shells. Finally, the two shells are ultrasonically welded to form a cavity and become one, that is, an anti-theft hard tag is obtained, which is often used for anti-theft of soft goods. After the customer selects the product, he can pay at the cashier, and the cashier will remove the hard label with a staple remover. If the thief tries to take the product out of the store without paying, the unremoved hard tag will trigger the alarm when the product passes through the alarm antenna ...

AI Technical Summary

Problems solved by technology

After aging, the overall performance and environmental adaptability of ABS plastics are significantly reduced, especially the impact strength will be greatly reduced, and they are relatively brittle and easy to break and break. Therefore, those skilled in the art believe that these waste ABS plastics are difficult to apply to the production Anti-theft hard tag case with better anti-theft effect

Therefore, there is no report currently on the market to adopt the acoustic magnetic / radio frequency anti-theft hard tag shell made of waste and old ABS plastics.
