The utility model discloses an efficient code-spraying device. The efficient code-spraying device is characterized by comprising a conveying belt (1), a machine frame (2), and a casing plate fixing frame (3), a driving roller (4), a driving motor (5), a driving compression roller (6) and a code-spraying device(7) which are installed on the machine frame (2). The conveying belt (1) is installed on the driving roller (4), and the driving roller (4) is driven by the driving motor (5). The driving compression roller (6) is installed on the machine frame (2) through an adjustable mechanism (8) and is arranged above the conveying belt (1). A code-spraying head of the code-spraying device (7) is placed above the conveying belt (1) and on one side of the driving compression roller (6). The efficient code-spraying device can print 1,000 casings for ham sausages in one minute, and therefore production efficiency is greatly improved.
