Abstract

A device for carving an eggshell comprises a sand blasting seal box. Two ends of the sand blasting seal box are provided with an access respectively. A conveyer belt is arranged within the sand blasting seal box. Two ends of the conveyer belt respectively pass through the accesses on the sand blasting seal box. Egg holders are uniformly arranged on the conveyer belt. A locating block is arranged beside each egg holder. The lower part of the conveyer belt is provided with a motor relay. The upper end face of the sand blasting seal box is welded with a supporting beam. A spray gun is mounted on the supporting beam. The upper end of the spray gun is connected to an air compressor, and the lower end passes through a viewing window to the interior of the sand blasting seal box to connect the spray gun. An iron hollow pattern is formed below spray nozzle of the spray gun close to the eggshell. The spray gun is located above the conveyer belt and is connected to a sand suction port via a sand suction pipe. A proximity switch is mounted at the nozzle of the spray gun. The spray gun is connected with a time solenoid valve. The time solenoid valve, the proximity switch and the motor relay are respectively connected to a PLC programming controller. The device of the invention has fast speed and low cost and is suitable for batch production. The success rate can be adjusted to be above 99 %.

Problems solved by technology

For example, in supermarkets, trademarks are basically printed on the outer packaging, which is easy to be stolen and replaced, and has no anti-counterfeiting effect.
