When the funnel is used, the height of the cone is adjusted by rotating the nut on the external thread of the rod, so that the adjustment of a gap between the cone-shaped shell and the funnel mouth is realized; the cross sections of the conical shell and the maximum feed inlet of the funnel mouth can be adjusted; the motor drives the penetrating shaft to rotate through the driving gear and the driven gear, and after the penetrating shaft rotates, the stirring rod stirs powder inside the premixing cylinder; meanwhile, the helical blades rotate to generate negative pressure between the conical shell and the funnel nozzle, so that powder in the storage barrel can easily enter the storage discharging pipe to prevent material blockage; the premixing feeding pipe can slide up and down in the feeding pipe of the machine barrel by being driven, and the support of the premixing barrel is supported by the elasticity provided by the spring; after the raw material is poured into the storage barrel, the raw material is sucked from a gap between the funnel nozzle and the conical shell and then is spread into the premixing barrel, most of powder falls onto the surface of the fixed plate, a small part of powder enters the lower part of the fixed plate through the strip-shaped through hole and is stirred with the powder in the premixing barrel, the rotary scraper plate rotates to scrape the powder on the surface of the fixed plate into the strip-shaped through hole, and the scraper plate scrapes the fixed plate to enable the powder to be initially stirred; then the powder enters the lower part of the fixed plate to be stirred again, the stirring effect of the powder is increased, the total weight of the premixing cylinder is increased along with the gradual increase of the amount of the powder entering the premixing cylinder, the total weight of the premixing cylinder is supported by the compression spring, the amount of the compression spring of the premixing cylinder is larger and larger at the moment, the cone and the penetrating shaft descend along with the premixing cylinder along the support rod, so that a gap between the cone-shaped shell and the funnel nozzle is gradually reduced, the flow rate of the material storage cylinder entering the premixing cylinder is increased, the dynamic speed regulation of the feeding speed of the premixing cylinder is realized, the premixing cylinder is ensured not to be filled, the stirring effect of the premixing cylinder is ensured, and the uniformity of the powder coating is improved; the mixing device can prevent the premixing cylinder from being lack of materials and ensure the uniformity of powder stirring; the single power mechanism can realize the functions of stirring and feeding pushing, has a simple structure and reduces the cost of equipment; the hollow sleeve is in sliding connection with the through shaft, so that unstable reaction force generated when the helical blades are used for pushing out powder is prevented from acting on the through shaft, the stress of the premixing barrel is more stable, and the weight of the powder in the premixing barrel and the compression amount of the spring form a rule.
The above description is only a preferred embodiment of the present invention, and all equivalent changes or modifications of the structure, characteristics and principles described in the present invention are included in the scope of the present invention.
