Buffering, the material guide bracket is vertically fixed on one side of the material receiving bracket through the material guide tube, the upper side of the material guide tube and the lower side of the material guide tube are connected by a circular arc transition, and the baffle swing groove is set on the guide Between the upper side of the material tube and the lower side of the material guide tube, the upper end of the blanking baffle provided in the swing groove of the baffle is hingedly connected to the material guide tube, and the material guide tube on one side of the blanking baffle is provided with a drop The upper end of the blanking connecting rod is hingedly connected to the material guide pipe, the lower end of the blanking connecting rod is vertically rotated along the side of the blanking baffle and connected with a rotating guide wheel, and the middle part of the blanking connecting rod is fixed with a blanking iron sheet. A blanking electromagnet is fixedly installed on the material guide tube on one side of the blanking iron sheet, and a pull rod spring is installed obliquely between the blanking connecting rod and the material guide tube, and the material guide tube is used to enable the material to be dropped to the guide material.

When the blanking electromagnet is energized with a magnetic force, the blanking electromagnet can generate an adsorption force with the blanking iron sheet, so that the blanking connecting rod is under the adsorption of the blanking electromagnet. Accurately in the vertical position, the blanking connecting rod can limit and guide the blanking baffle, so that the blanking baffle can be accurately in the vertical position, so that the ring-shaped workpiece in the material guide tube can be blocked, so that The ring-shaped workpiece in the material guide tube stops falling. When the blanking electromagnet loses its magnetic force when it is powered off, the blanking electromagnet can lose the adsorption force between the blanking iron sheet, and the ring-shaped workpiece in the material guide tube uses its own gravity to push the blanking. The baffle, the blanking baffle is in a tilted state, so that the lowermost ring-shaped workpiece in the material guide tube falls smoothly. Quickly pulled to the vertical state under the action of the blanking rod, and the blanking rod can be After the iron is electrified with magnetic force, it is accurately fixed at the vertical station. Using the blanking baffle at the vertical station can realize the limit blocking of the ring-shaped workpieces in the material guide tube, ensuring that the ring-shaped workpieces can be lowered one by one. For material transmission, use the lower end of the blanking rod to rotate vertically along the side of the blanking baffle to connect with a rotating guide wheel, so that the blanking baffle can swing back and forth smoothly, avoiding the gap between the lower end of the blanking connecting rod and the blanking baffle. The large friction force causes the swing of the blanking baffle to be blocked. The lower end of the blanking baffle is horizontally rotated to connect with the material guide wheel, so that when the blanking baffle swings to the inclined state, the material guide tube is the most The ring-shaped workpiece at the lower end can be smoother under the rolling action of the material guide wheel during the sliding process, avoiding the friction between the lower end of the blanking baffle and the ring-shaped workpiece to cause the ring-shaped workpiece to slide down and jam. Through such a structure, the present invention has a reasonable structural design, can realize multiple ring-shaped workpieces combined for transmission, and can ensure that the ring-shaped workpieces are unloaded and conveyed one by one, improving the degree of automation of workpiece transmission and processing, and meeting the needs of processing and use.
