Description

Technical Field

[0001] The utility model relates to the technical field of inkjet printers, in particular to a dust explosion-proof inkjet printer. Background Art

[0002] Inkjet printer is a device that uses software control and non-contact method to mark products. It can print clear and lasting text, numbers, patterns and other information on the surface of various materials. Inkjet printer is widely used in food, beverage, medicine, daily chemical, electronics and other industries, which can effectively improve production efficiency and product quality traceability.

[0003] When existing inkjet printers work in an environment with high dust density, there are no protective measures on their nozzles, which may cause dust to reach the inside of the equipment through the nozzles. Because the equipment generates heat when working, excessive dust accumulation inside the equipment may cause an explosion. At the same time, there are no guide facilities above the conveyor belt, which causes the product to shift in position when moving above the conveyor belt, resulting in missed spraying.
