This utility model relates to the field of injection molding equipment technology and discloses a high-flowability plastic injection molding machine, including an injection tube. A hopper is fixedly installed on one side of the top surface of the injection tube. Cavities are opened on both sides of the inner wall of the hopper. A melting component is fixedly installed inside the cavity. A filter screen is fixedly installed at the bottom of the inner wall of the hopper. A hopper cover is snapped onto the top surface of the hopper. This high-flowability plastic injection molding machine, through the arrangement of a crushing mechanism, a melting component, and a heat preservation component, allows plastic raw materials to be fed into the hopper. An electric heating grid heats and melts the raw materials after being energized. A servo motor drives a crushing rod to rotate, rapidly crushing the raw materials for faster melting. The filter screen filters out impurities to avoid affecting product quality. The molten plastic flows into the injection tube, where an electric heating plate heats and insulates the tube. Rock wool and polyurethane sleeves provide insulation, reducing heat loss, ensuring the flowability of the molten plastic, and preventing solidification.

The utility model discloses high-digestibility pet food formula mixing equipment, which relates to the technical field of pet food processing, and comprises a mixing cylinder, the top end of the mixing cylinder is fixedly connected with a fixed frame, and the top of the fixed frame is provided with a movable mechanism. The raw materials are effectively prevented from being agglomerated or layered due to single-direction movement in the mixing process, various raw materials in the mixing barrel can be uniformly distributed along with periodic change of the stirring direction, the mixing effect is remarkably improved, the mixing time is shortened, and the overall uniformity and quality are improved. Residues in the equipment can be reduced, the cleaning process is simplified, the service life of the equipment is prolonged, the maintenance frequency is reduced, and high-quality and uniform production of pet food is ensured through the efficient and stable stirring mode.
