Ancient coin dust removal device

Abstract

The invention provides an ancient coin dust removal device, and belongs to the technical field of machines. The ancient coin dust removal device comprises a bucket body and a bucket cover arranged onthe bucket body. A variable frequency motor is fixed in the bucket body, and a rotary shaft is vertically fixed in the bucket body. The lower end of the rotary shaft and the bucket body are axially fixed. The variable frequency motor can drive the rotary shaft to rotate through a transmission mechanism. Clamp plates in a flat plate shape are vertically arranged on the top wall of the rotary shaft.The two clamp plates are arranged side by side. A clamping opening used for clamping the edge of an ancient coin is formed between the two clamp plates, one clamp plate is fixedly connected with therotary shaft, and the other clamp plate is detachably and fixedly connected with the rotary shaft. A spray gun is further fixed in the bucket body. A conic spray head communicating with an outlet of the spray gun is fixedly connected to the spray gun. The axis of the spray head extends in the horizontal direction. The large-diameter end opening in the spray head right faces the ancient coin. A nitrogen pipe is arranged outside the bucket body. A gas inlet end and a gas outlet end are arranged at the two ends of the nitrogen pipe correspondingly, and the gas outlet end stretches into the bucketbody and communicates with an inlet of the spray gun. The ancient coin dust removal device has the beneficial effect of being good in dust removal effect.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a dust removal device, in particular to an ancient coin dust removal device. Background technique [0002] Ancient coins refer to ancient metal coins and their derivatives, which have high collection value. In order to better protect ancient coins, the existing practice is to individually package each ancient coin 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. However, there is a problem with the above-mentioned packaging method: the ultrasonic packaging machi...

AI Technical Summary

Problems solved by technology

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

However, due to the complex textures on ancient coins, it is extremely difficult to clean the dust embedded in the texture. It is more difficult to clean with a spray gun, and the cleaning effect is not very good.
