The auxiliary feeding device comprises a supporting plate, a supporting column is installed on the outer wall of one side of the supporting plate through a bolt, a tank body is installed at the center of one side of the bottom of the supporting plate through a bolt, and a conical shell is installed at an opening in one end of the inner wall of the tank body through a bolt. A weighing sensor is mounted in the center of one side of the inner wall of the tank body through a bolt; during feeding, the driving assembly is operated to rotate, the connecting shaft pipe drives the grinding block to rotate, and the rotating grinding block is matched with the conical shell to shear and crush materials at a high speed and eliminate caking, so that active ingredients are prevented from being agglomerated during subsequent mixing; the linkage design of the weighing barrel and the weighing sensor is combined with the thread control structure of the discharge valve, so that the weight of materials can be monitored in real time, accurate control over feeding errors is achieved, the matching precision of key raw materials such as silicone oil and an emulsifier is ensured, error accumulation of traditional manual feeding is avoided, and the stability of product batches is guaranteed.

This utility model relates to the field of road construction technology, and in particular to a seamless expansion joint material production device. The feeding mechanism is connected to the inside of the mixing cylinder, and the heating mechanism is connected to the cylinder body jacket. A discharge port is provided at the bottom of the mixing cylinder. The device adopts a multi-axis linkage mixing mechanism, which can achieve three-dimensional shearing and convection mixing of multi-component, high-viscosity raw materials, eliminating material agglomeration and stratification. The heating mechanism ensures that the mixing temperature is maintained at 20~30℃, guaranteeing that the reactivity of the polyurethane material remains at a normal level; solving product quality problems caused by inaccurate temperature control and uneven heating of raw materials. The mixing cylinder adopts a fully enclosed structure, which can avoid heat loss and reduce uneven proportions caused by material scattering. A high-polymer anti-stick coating and a self-cleaning scraper assembly are installed inside the mixing cylinder to simultaneously scrape off adhering materials during the mixing process, effectively removing material from the inner wall of the mixing cylinder.

This disclosure relates to the technical field of equipment for grinding wheel production. One embodiment of this disclosure provides a feeding device for grinding wheel production, comprising: an equipment frame, a first cylinder, a second cylinder, and a pair of pusher plates. The first cylinder and the second cylinder are respectively mounted on the two side surfaces of the equipment frame. The pusher plates are located at the output ends of the first cylinder and the second cylinder. A top frame is fixed to the top of the equipment frame. A leveling component is mounted on the top frame. Both a low-level material tank and a high-level material tank are mounted on the equipment frame and fixed to a support. A conveying pipe is provided at the bottom of both the low-level and high-level material tanks. A spiral pusher is installed inside the conveying pipe, and the spiral pusher is rotated by a motor. A discharge pipe is provided at the bottom of the conveying pipe. This technical solution solves the technical problem that existing grinding wheel production feeding machines generally use a single feeding mechanism and rely solely on high-quality materials for production, a traditional model that brings many problems that urgently need to be addressed.
