This utility model provides a grinding mill for pet food processing. The grinding mill includes: a support frame, on the top of which a grinding mill housing is fixedly installed, and on the top of which a top cover is installed; a grinding assembly, mounted on the top cover, used for grinding pet food raw materials; a drying mechanism, installed in the inner cavity at the bottom of the grinding mill housing, used for drying the ground powder; and a receiving assembly, installed at the bottom of the grinding mill housing. Under the action of the grinding assembly, the grinding disc drives the fixedly connected connecting shaft to rotate, which in turn drives the connecting rod fixedly connected to the side surface to rotate. The connecting rod drives a stirring rod to agitate the ground powder. Combined with the operation of the bottom electric heating plate, this facilitates powder agitation, improves the drying effect, ensures the drying performance of the powder, and prevents powder adhesion and accumulation during subsequent discharge.

The application discloses a multifunctional power supply board card based on instruction control and a control system thereof, relates to the technical field of multifunctional power supply board cards, and comprises a power supply board card main body, a connecting line plate is fixedly installed on one side of the top of the power supply board card main body, mounting clamping grooves are fixedly installed in the middle of the two sides of the top of the power supply board card main body, connecting clamping blocks are clamped on the top of the inner side of the mounting clamping grooves, and a protective top plate is fixedly connected on the top of the two connecting clamping blocks. The elastic protection telescopic bag is expanded to protect the outer side of the power supply board card main body, dust accumulation on the outer side of the power supply board card after long-time use is effectively prevented, heat generated by the power supply board card main body is absorbed and conducted by the elastic protection telescopic bag and the insulating oil in the elastic protection telescopic bag, the heat dissipation fins are used for assisting heat dissipation during use of the power supply board card, and therefore, the use safety and stability of the power supply board card are effectively improved.

The utility model relates to the technical field of bar code reading, in particular to bar code reading equipment with a protective structure, which comprises an identification head and a support, connecting plates are symmetrically and fixedly connected to the side walls of the support, rotating shafts are fixedly connected to the side walls of the two ends of the identification head, and the ends of the rotating shafts are rotatably connected with the side walls of the connecting plates. The power assembly is arranged, the power assembly is used for driving the sliding assembly to work, the movable plate is driven to slide in the working process of the sliding assembly, and therefore the cleaning brush is used for cleaning a lens at the end of the recognition head, and dust is prevented from being accumulated at the end of the recognition head; and when the angle of the identification head needs to be adjusted, a limiting assembly is pulled outwards, so that the limiting assembly is separated from a tooth groove, a rotating shaft and a connecting plate can rotate, and the technical problem that the angle adjustment work of the device can be realized by rotating the identification head is solved.
