Detailed Description
The present invention is further described with reference to the following detailed description and accompanying drawings:
referring to fig. 1, the powder weighing device for cable materials comprises a bracket, a hopper and a weighing sensor; the bracket is composed of a plurality of upright posts and a cross beam connected between the upright posts; a space for placing the hopper is arranged at the position of the perpendicular bisector of the bracket; the weighing sensors are connected to the bracket and are symmetrical around the middle vertical line of the hopper; the outer wall of the hopper is connected with a convex ring, and the convex ring is pressed on the surface of the weighing sensor; the outlet of the hopper is internally connected with a valve (an electric butterfly valve is adopted in the embodiment) which can be opened and closed. The device also comprises a blowing device;
the blowing device comprises an air nozzle, an air pipe and an air valve assembly;
the support is fixedly connected with a sleeve, the sleeve is arranged above the hopper, an outlet of the sleeve is connected with a feed inlet of the hopper through a plastic cylinder film, and the length of the plastic cylinder film is greater than the maximum distance between the outlet of the sleeve and the feed inlet of the hopper; the air pipe is provided with a plurality of air pipes, and an air outlet at the rear part of each air pipe is connected with an air nozzle; the air pipe is vertically connected with the side wall of the sleeve, each air nozzle is positioned in the space in the hopper, and each air nozzle faces the side wall of the hopper;
and the air pipe is connected with an air valve assembly.
The inlet of the sleeve is used for connecting a feeding pipeline.
In order to reduce the material flowing through the sleeve to remain on the air pipe, the main body of the front portion of the air pipe is arranged on the outer wall of the side wall of the sleeve, and the rear portion of the air pipe extends into the inner cavity of the sleeve from the bottom edge of the sleeve and extends into the hopper.
In actual use, the air pressure of a standard compressed air source in a factory building is found to be stable. If a common electromagnetic valve is adopted to control air blowing, the air blowing state only comprises high-pressure air blowing and a zero-pressure state. The blowing effect on powder remained on the side wall of the hopper is good, but the excessively strong airflow can cause the material in the hopper to rise. For this reason, a better gas valve assembly is specially designed.
The air inlets of the air pipes are connected with the outlet of the same air valve component through a multi-way connector (4 air pipes are adopted in the embodiment, and a 5-way connector is adopted);
as shown in fig. 2, the air valve assembly comprises a shell, a hose, a spring pressing sheet and a motor; a tubular cavity is arranged in the shell, and the hose is arranged in the tubular cavity; a hollow window is formed in the side wall of the tubular cavity, a spring pressing sheet is connected to the outer surface of the hollow window, and one end of the spring pressing sheet is fixed to the outer surface of the hollow window; the rotor of the motor is connected with an eccentric wheel, and the path of the outer edge of the eccentric wheel passes through the upper surface of the spring pressing sheet. Here, the spring pressing piece is an elastic metal piece.
In actual use, the motor adopts a stepping motor, and the degree of compression of the eccentric wheel to the spring can be properly adjusted through the stepping control of the motor, so that the ventilation section in the hose is adjusted, and the air outlet pressure of the air tap is adjustable. In the using process, the air outlet pressure of the air tap is continuously changed if the motor is in a continuous rotating state, so that the effect of removing the residual powder in the hopper is better. Is particularly suitable for the periodic material cleaning link of equipment.
In this example, the motor and housing of the valve assembly are mounted on the cross-member of the bracket.
