This invention relates to a collaborative control method, apparatus, and equipment for a dual-track loading and feeding system, belonging to the field of railway loading technology. In this method, apparatus, and equipment, when the target car reaches a switching threshold during loading, it switches to the replenishment stage. By setting replenishment priority determination rules, the replenishment sequence of the two tracks is clearly defined, avoiding the problem of insufficient or accumulated material in the buffer bin caused by simultaneous replenishment, resolving the conflict problem of dual-track operations, and improving loading efficiency and accuracy. Furthermore, during the replenishment stage, a fuzzy PID fusion collaborative adjustment algorithm is used to adjust the parameters of multiple devices in a coordinated manner, stabilizing the material level in the buffer bin within the ideal range of 30%-50%. This ensures that coal flows directly into the chute with stable flow fluctuations, eliminating the need for secondary leveling, stabilizing the replenishment conditions, and significantly improving loading accuracy. Simultaneously, it avoids equipment overload caused by material accumulation and blockage, reduces the frequency of air cannon activation, and lowers equipment wear and energy consumption.

This invention discloses an injection molding die for PVC pipe fittings, belonging to the field of injection molding technology. It includes: a fixed mold base with a first water-cooling plate fixed to one end face; a sliding mold base, parallel to one side of the fixed mold base; a fixed template, installed on the end face of the first water-cooling plate near the sliding mold base; a movable template, fixed to the side of the sliding mold base near the fixed template; two mold cavities, symmetrically arranged in the fixed template; and two core guide units, each installed in one of the mold cavities on the fixed template. In this invention, the fixed template and the movable template can fit tightly together to form two injection molding cavities for the PVC pipe fittings. The core shaft in the main shaft core device can be eccentrically or coaxially distributed with the mold cavity as the shaft rotates, which facilitates rapid filling of the mold with PVC material, shortens the injection cycle, prevents material shortages or incomplete filling due to flow obstruction, and improves product quality.

This utility model discloses a slag powder conveying device for cement production, relating to the technical field of conveying devices. The utility model includes a conveying pipe, and further includes: a conveying section mounted on the conveying pipe; an adjusting section mounted on the conveying pipe; and a locking section mounted on the adjusting section.
