Perforation anti-counterfeiting device of finished piece box body

Abstract

The invention relates to a perforating device, in particular to a perforation anti-counterfeiting device of a finished piece box body which is applicable to a conveyor belt, which belongs to the technical field of the perforating device. The perforation anti-counterfeiting device comprises a rotary knife roll (1), an air cylinder (2), a position detector I (3), a position detector II (4) and a control circuit; the rotary knife roll is connected with the air cylinder, and the air cylinder is installed on supports on two ends of a conveying track machine body; the position detector I and the position detector II are sequentially installed on two ends of a transportation track and used for detecting different positions of a finished piece box body on the transportation track; the position detector I and the position detector II transmit a position signal to the control circuit, and the control circuit is connected with the air cylinder. Whether the finished piece box body is manually secondarily opened is authenticated by adopting the perforation technology, on one hand, the perforated adhesive tape is easy to break; on the other hand, after the box body is sealed, the perforated adhesive tape cannot be completely overlapped again with all holes on a perforated box wrapper, so that an anti-counterfeiting effect is realized.

Description

technical field [0001] The invention relates to a punching device, which is especially suitable for a punching anti-counterfeiting device for finished product boxes on a conveyor belt, and belongs to the technical field of punching equipment. Background technique [0002] Box sealing packaging is a widely used packaging technology in the market, and most of the sealing of the finished box is made of adhesive tape. However, due to the many links and personnel involved in the storage and transportation of finished parts, the problem of lost or exchanged finished products in the box frequently occurs. After verification, most of them are caused by manual removal of the second unpacking. At present, there is a kind of tear-off bottom sealing tape used in the market, which is used for sealing tape. When the tape is torn off again after pasting, part of the bottom glue will remain on the surface of the object. If it is pasted again, it cannot be restored. This identifies whether ...

Problems solved by technology

However, after this tape is heated with a hair dryer, iron, etc., when it is torn off again, the tape will not be damaged, and the primer will not remain on the surface of the object, and it can be pasted again for recovery, so the anti-counterfeiting effect is not obvious; and the price is more expensive , high volume use will increase the cost
