About the introduction of sand blasting machine


The sand blasting machine realizes automatic sand blasting through an electrical control system, which can automatically adjust the blasting angle, blasting time, blasting distance, back blowing time, the movement of the blasting gun, the speed of the worktable, etc. The electrical control system is mainly composed of X-axis traverse component, Y-axis vertical displacement component, table rotation component, sand blasting component, blow-cleaning component, dust removal component and other parts. All components are made by LM series PLC according to the touch screen in advance. The set parameters are uniformly coordinated and controlled, and the blasting process is completed efficiently and reliably.
The X-axis traverse assembly consists of a stepper motor, a screw, a guide rail, a slider, a limit switch, and an incremental encoder. The stepping motor receives the LM series PLC high-speed pulse signal, and drives the screw to rotate at a certain speed, so that the slider moves left and right on the guide rail. The encoder collects the number of turns of the screw to form a closed-loop control system of X-axis movement. Each limit switch is installed at the extreme position of the left and right slider movement to ensure the safety of the slider movement and avoid accidents caused by speeding.
The Y-axis longitudinal movement component is the same as the X-axis component. It consists of a stepper motor, a screw, a guide rail, a slider, a limit switch, and an incremental encoder. The slider is moved up and down on the guide rail. The encoder collects the number of turns of the screw to form a closed-loop control system of Y-axis movement. Two limit switches are installed at the extreme position of the slider to ensure the safety of the slider movement. Sex, there will be no accidents of speeding.
The worktable rotation assembly consists of a servo motor, a worktable, and a reducer. The servo motor is set to speed control mode. It adopts LM series PLC analog output control. After decelerating through the reducer, the work surface is rotated at a constant speed. The speed can be changed through the touch screen. Due to the large inertia of the work table, the servo motor is set to speed up and start. And deceleration stop to reduce the damage to the servo motor caused by overshoot.
The sand blasting component and the blowing component are mainly composed of a spray gun, an air gun, a sand outlet valve, an air outlet valve, an air source, and a filter. Control the pressure in the pipeline to ensure the strength of the blasting. The larger the pressure value, the higher the speed of the blasting flow, the higher the blasting efficiency, and the rougher the surface of the workpiece. Otherwise, the surface is relatively smooth. Adjusting the on-time of the sand outlet valve and air outlet valve can control the sand blasting time and blowing time to ensure the effect of sand blasting treatment. The sand blasting time and blowing time can be set on the touch screen.
The dust removal component is composed of a dust removal unit, a backflush solenoid valve, and a filter element. The filter element dust removal unit configured in the equipment integrates secondary dust removal into one, and can be used for gas treatment with high dust concentration in conjunction with adjusting different backflush intervals. For dust particles of class 015μm and above, the dust removal efficiency is as high as 99199%, and the purified air achieves a near-zero emission state, which improves the filtration accuracy by more than 100 times than that of a traditional bag filter, which greatly reduces the air pollution caused by dust emission. Pollution.
