Detailed Description
The invention is further described with reference to the following figures and examples.
Referring to fig. 1-5, the control method of the intelligent protection system for abrasive belt breakage in hammerhead grinding comprises an adjusting cylinder 9 for tensioning or loosening an abrasive belt 8, a hydraulic station motor 4 connected with a hydraulic circuit, and a programmable controller 7 written with an intelligent protection program for abrasive belt breakage, wherein the programmable controller 7 realizes the intelligent protection function for abrasive belt 8 breakage by writing with the intelligent protection program for abrasive belt breakage; an input contact 7.1 of the programmable controller 7 is connected with a hydraulic circuit through a controller starting button SB2 and a magnetic switch SP1, and an output contact 7.2 of the programmable controller 7 is connected with the hydraulic circuit through an air cylinder electromagnetic valve 5; a magnetic ring is arranged on the adjusting cylinder 9, the magnetic ring moves along with a piston rod on the adjusting cylinder 9, and after the abrasive belt 8 is installed by an employee, the magnetic ring needs to be adjusted to a position where a magnetic switch SP1 just has a signal; when the magnetic ring on the adjusting cylinder 9 is not in the detection range of the magnetic switch SP1, the abrasive belt breakage intelligent protection program controls the hydraulic station motor 4 to stop, and the cylinder electromagnetic valve 5 is disconnected.
Furthermore, a buzzer 6 is arranged between the output contact 7.2 on the programmable controller 7 and the hydraulic circuit.
Further, the hydraulic station motor 4 is connected to a hydraulic circuit through the thermal relay 3, the contactor 2 and the circuit breaker 1 in sequence.
Further, the output contact 7.2 on the programmable controller 7 is connected with a hydraulic circuit through a thermal relay contact FR1 on the thermal relay 3 and a contact coil KM2 on the contactor 2 in sequence.
Further, the detection range of the magnetic switch SP1 is only 10 mm.
Furthermore, an integrated power supply 7.3 is arranged on the programmable controller 7; in addition, the programmable controller 7 may monitor inputs and modify outputs according to user program logic, which may include boolean logic, counting, timing, complex mathematical operations, motion control, and communication with other intelligent devices.
The control method of the intelligent protection system for breakage of the hammerhead sanding belt comprises the following steps:
A. powering on the hammer head grinding equipment, carrying out self-checking on the abrasive belt breakage intelligent protection system, and if the magnetic switch SP1 detects a signal from the magnetic ring, confirming that the hammer head grinding equipment enters a normal working state;
B. a starting button on the hammer head polishing equipment is pressed, the cylinder electromagnetic valve 5 is switched on, the abrasive belt 8 is tensioned, and the polishing motor 10 is started to perform polishing work;
C. in the polishing process, if the magnetic switch SP1 does not detect a signal from the magnetic ring, the polishing motor 10 stops working, the cylinder electromagnetic valve 5 is disconnected, the abrasive belt 8 is loosened, and the buzzer 6 gives an alarm;
D. the worker adjusts or changes the abrasive belt 8 according to actual conditions, when the adjustment or the change of the abrasive belt 8 is completed, a starting button on the hammer head grinding equipment is pressed, the magnetic switch SP1 detects a signal from the magnetic ring, the grinding work is continued, and the magnetic switch SP1 continuously monitors the signal of the magnetic ring.
Further, there are at least the following three cases in practical use: when the air pressure on the adjusting cylinder 9 is adjusted to be too small, so that the abrasive belt 8 is not tensioned, the magnetic ring on the adjusting cylinder 9 is not in the detection range of the magnetic switch SP1, and no signal is output from the magnetic switch SP 1; when the air pressure on the adjusting air cylinder 9 is adjusted to be too large, the magnetic ring on the air cylinder exceeds the detection range of the magnetic switch SP1, and no signal is output from the magnetic switch SP 1; third, when sanding belt 8 approaches or exceeds the service life span, sanding belt 8 will become longer and longer due to the physical characteristics of sanding belt 8, resulting in a change of signal from magnetic switch SP 1. The implementation measures for the above three cases are as follows: when no signal is output by magnetic switch SP1, the intelligent protection program for abrasive belt breakage immediately controls hydraulic station motor 4 to stop working, and disconnects cylinder solenoid valve 5 and triggers buzzer 6 to give an alarm to remind staff to adjust or replace abrasive belt 8.
