Technical Field
[0001] The utility model relates to the technical field of valve production, in particular to the technical field of automatic grinding lines for small and medium-sized valve plates. Background Art
[0002] The butterfly valve, also known as the flap valve, is a simple regulating valve that can be used to switch low-pressure pipeline media and control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. The butterfly valve opening and closing part is a disc-shaped valve plate that rotates around its own axis in the valve body to achieve the purpose of opening, closing or regulating.
[0003] During the production process of the valve plate, the surface of the valve plate needs to be polished. At present, when polishing the surface of the valve plate, the valve plate is usually fixed first, and then the surface of the valve plate is manually polished by a handheld polishing device. Not only is the working environment dusty, which is detrimental to the health of the workers, but the labor intensity of the workers is also high and the working efficiency is low.

The grinding conveyor is composed of a machine base, a grinding conveyor belt and a motor. The grinding conveyor belt is installed at the right end of the valve plate conveyor through the machine base, and its feed port is correspondingly connected with the discharge port of the valve plate conveyor. A grinding belt is attached to the grinding conveyor belt. The motor is fixedly mounted at one end of the machine base, and the motor is drivingly connected to the grinding conveyor belt. Guard plates are fixedly mounted on the machine base on both sides of the grinding conveyor belt, and fixed bars in a row are fixedly mounted on the guard plates. Through grooves are provided on the fixed bars. The first corrugated bars in pairs are respectively fixedly mounted on the inner sides of the guard plates on both sides, and screw rods in a row are fixedly arranged above the second corrugated bars. The second corrugated bars are fixedly mounted on the fixed bars through screw rods in a row using nuts. The cylinders in a row are arranged at an angle and correspond to the interval between the second corrugated bars and the first corrugated bars. A material storage table is fixedly mounted at the end of the machine base.
[0007] Preferably, the touch switch is arranged obliquely and corresponds to the outermost first corrugated strip.
[0008] Preferably, the second corrugated strips are arranged in rows.
[0009] Preferably, a concave arc-shaped push head is fixedly mounted on the front end of the telescopic rod of the cylinder.
[0010] The beneficial effects that can be achieved by the utility model using the above technical solution are:
[0011] 1. Install the grinding conveyor belt on the machine base, attach the grinding belt to the grinding conveyor belt, set the first corrugated strip and the second corrugated strip above the grinding conveyor belt, push the valve plate onto the grinding conveyor belt between the corrugated strips, and the grinding conveyor belt will drive the valve plate to move backward. During this process, the valve plate is conveyed backward while rotating and rubbing under the limiting and guiding action of the corrugated strips, thus realizing the automatic and uniform grinding of the valve plate, improving the grinding efficiency, and also greatly reducing the labor intensity of the staff;
[0012] 2. The cylinders are arranged in a row at an angle on the installation platform, and a concave arc-shaped pusher is fixedly installed at the front end of the telescopic rod of the cylinder. When the valve plate conveyor conveys the valve plate to touch the touch switch, the valve plate conveyor stops, and the cylinder pushes the valve plate onto the grinding conveyor, thereby achieving uniform gap feeding of the valve plate;
[0013] 3. By fixing the second corrugated strip on the fixing strip through a row of screws and nuts, the spacing between the corrugated strips can be adjusted according to the diameter of the valve plate to meet different valve plate grinding needs. BRIEF DESCRIPTION OF THE DRAWINGS
