This utility model discloses a doctor blade system and a cardboard printing machine. The doctor blade system includes: a mounting frame and a doctor blade mounted on the mounting frame; multiple nozzles spaced apart on the side of the mounting frame away from the doctor blade, each nozzle having a fan-shaped outlet and capable of spraying cleaning fluid towards the doctor blade; the mounting frame has a return channel with a bottom wall, including a first end and a second end opposite to each other. The first end extends to the doctor blade, and the bottom wall gradually slopes downwards from the first end to the second end. The nozzles spray cleaning fluid towards the doctor blade, thereby automatically cleaning the doctor blade. The inclined bottom wall of the return channel improves ink return efficiency.

This utility model relates to a two-stage cooling structure for the motor rotor of a compressor, comprising a front housing and a rear housing mounted together from left to right. A cooling inlet is connected to the right side of the motor cooling cavity located inside the motor housing. A high-pressure hot gas outlet is connected to the right side of the main compression flow channel. The high-pressure hot gas outlet is connected to a cooler via a high-pressure hot gas connecting pipe, and the cooling inlet is connected to the cooler via a cooling inlet connecting pipe. Several guide vanes are evenly distributed along the circumference on the right side of the impeller, and a drain outlet connected to the motor cooling cavity is provided on the left side of the motor housing. This utility model utilizes the high-pressure hot gas compressed by the compressor, which, after cooling, effectively cools the surface of the motor stator and rotor assembly, forming a closed gas circulation path inside the compressor, avoiding high-temperature accumulation and improving equipment operational reliability.
