Embodiment 1

[0011] Embodiment 1 The composition of an automatic control device for the rotation of a belt pulley and the functions of its components:

[0012] The device consists of forward contactor 1, reverse contactor 2, current transformer 3, ammeter 4, low-voltage control cabinet 5, field control panel or remote control 6, signal control cable 7, PLC programmable device 8, PLC program 9 Composition, the automatic control device for the rotation of the pulley controls the forward rotation contactor 2 and the reverse rotation contactor 4 through the operation of the PLC program 9 to achieve the forward and reverse control of the motor, so as to replace the manual rotation of the pulley. The on-site control panel or remote controller 6 can be configured for manual operation on site. The current transformer 3 is used to detect the current value of the motor. The ammeter 4 is used to display the current value of the motor.

Embodiment 2

[0013] Embodiment 2 The working principle of an automatic control device for belt pulley rotation:

[0014] When the ball pressing equipment is blocked due to the uneven feeding of the upper material conveying link, causing the motor load to be overloaded and causing a shutdown failure, the current value detected by the current transformer 3 displayed by the ammeter 4 should be at a higher level. In the range interval, the PLC program 9 will control the forward and reverse actions according to the detected value until the motor current output value during the forward and reverse process reaches the program setting value, which means that the material blockage fault has been eliminated.

Abstract

The invention relates to a belt pulley rotation automatic control apparatus. The apparatus is composed of a forward contactor 1, a reverse contactor 2, a current transformer 3, an ammeter 4, a low-voltage control cabinet 5, an onsite control panel or remote controller 6, a signal control cable 7, a PLC programming device 8 and a PLC program 9. The belt pulley rotation automatic control apparatus controls the forward contactor 1 and the reverse contactor 2 through the operation of the PLC program 9 to control forwarding and reversing of a motor so as to replace manual rotation of a belt pulley. The belt pulley rotation automatic control apparatus mainly has the following advantages: the test method is scientific and accurate; and the manual rotation is replaced, automatic operation is realized, and the fault elimination time is shortened.

Description

technical field [0001] The invention relates to an automatic control device for the rotation of a belt pulley, which belongs to the technical field of automatic control of electromechanical equipment. Background technique [0002] At present, domestic magnesium metal pelletizing equipment often suffers from clogging caused by uneven feeding in the upper material conveying link, resulting in overloading of the motor, resulting in shutdown failures. The way to deal with this type of downtime failure at present is: manual positive and negative rotation of the belt pulley to eliminate the failure. Contents of the invention [0003] The object of the present invention is to provide a fully automatic control device that replaces the manual rotation of the pulley and uses the display data of the detected current value to alternately drive the output shaft of the motor to rotate forward and reverse. In order to realize the purpose of the above invention, it is achieved through th...
