Ancient coin packaging device

Abstract

The invention provides an ancient coin packaging device and belongs to the technical field of machines. The problem that an existing packaging device is poor in packaging quality is solved. The ancient coin packaging device comprises an ultrasonic packaging machine body and a box, and the ultrasonic packaging machine body is located in the box. A sealed cavity is formed between the box and the ultrasonic packaging machine body, and a separation plate for separating the sealed cavity into a dust removal cavity and a packaging cavity is arranged in the box. A packaging area is located in the packaging cavity, a through hole penetrates through the separation plate, and cloth capable of covering the through hole is arranged on one side of the separation plate. An opening is formed in the frontside wall of the box, and a box door is hinged to the edge of the opening. An inserting opening penetrates through the front side wall of the box, and a first glove is fixedly connected in the inserting opening. A nitrogen pipe and an evacuating device capable of vacuumizing the sealed cavity are arranged outside the box. A spraying gun is arranged in the dust removal cavity, and the two ends ofthe nitrogen pipe are a gas inlet end and a gas outlet end correspondingly. The gas outlet end communicates with the dust removal cavity, and the gas outlet end communicates with the spraying gun through a hose. The ancient coin packaging device has the beneficial effect of being high in packaging quality.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a packaging device, in particular to an ancient coin packaging device. Background technique [0002] Ancient coins refer to ancient metal coins and their derivatives, which have high collection value. In order to protect the ancient coins better, the existing way is that each ancient coin is individually packaged in a PVC protective box. [0003] The existing ancient coin packaging steps are as follows: The PVC protective box is composed of an upper cover and a lower cover both made of PVC material, the ancient coin is placed in the lower cover, then the upper cover is closed, and the above-mentioned whole is put into the ultrasonic In the packaging area of ​​the packaging machine, the upper cover and the lower cover are fixed together to complete the entire packaging process. [0004] However, there is a problem with the above-mentioned packaging method: the ultrasonic packagi...

Problems solved by technology

[0004] However, there is a problem with the above-mentioned packaging method: the ultrasonic packaging machine will generate large vibrations during the packaging process. If the dust attached to the ancient coins, the upper cover or the lower cover is not cleaned, the above-mentioned dust will vibrate. Floating and gathering to form spots under the action, which seriously affects the aesthetics of the encapsulated ancient coins, and the quality of the encapsulation is greatly reduced
