Problems solved by technology

[0003] The mixer mainly uses the motor to provide kinetic energy to carry out the mixing operation. However, when the mixer encounters foreign objects stuck to the stirring rod during the mixing operation, forcibly blocking the stirring rod for a long time will cause damage to the motor or the speed change gear of the motor. Affect the normal use of the mixer

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0024] refer to figure 1 , the present invention also proposes a control method for anti-jamming of a bidirectional motor for a mixer, comprising the following steps:

[0025] The pull-in time of the relay a2 and the relay b3 is controlled by the single-chip microcomputer 1, both the relay a2 and the relay b3 are electrically connected to the motor 4, and the relay a2 is used to control the forward rotation of the motor 4, and the relay b3 is used to control the reverse rotation of the motor 4;

[0026] When the motor 4 is running forward, the cycle continues in the order that the relay a2 is closed, the relay a2 is disconnected, the relay b3 is disconnected, the rel...

Abstract

The invention discloses an anti-locking control method of a bidirectional motor for a stirrer. A single chip microcomputer controls the actuation time of a relay a and a relay b, the relay a and the relay b are both electrically connected with a motor, the relay a is used for controlling forward rotation of the motor, and the relay b is used for controlling backward rotation of the motor. In the present invention, the relay a and the relay b are used for controlling the motor to perform forward and reverse rotation switching in the process of driving the stirrer to operate; the situation thatwhen the stirrer encounters foreign matter and clamps a stirring rod, the running state of the motor is prevented from being clamped forcibly for a long time, the motor or a motor speed change gear isprevented from being damaged, damage to the stirrer due to the fact that the stirring rod is clamped by the foreign matter is prevented, and in addition, the method is simple, convenient, low in intelligent requirement for composition equipment and high in practicability.

Description

technical field [0001] The invention relates to the related fields of mixers, in particular to a control method for preventing jamming of bidirectional motors used in mixers. Background technique [0002] A mixer is a machine with a bladed shaft that rotates in a cylinder or a tank to stir and mix various raw materials to make it a mixture or a suitable consistency. Mixers are divided into forced mixers, single-shaft mixers, twin-shaft mixers, etc. The mixer is widely used in high-efficiency equipment for stirring, dispersing and dissolving coatings and solids. The equipment is composed of five parts: hydraulic system, main drive, mixing system, guiding mechanism, and electric control box. The structure of each part of the equipment is compact and reasonable. [0003] The mixer mainly provides kinetic energy through the motor to carry out the mixing operation. However, when the mixer encounters foreign objects stuck to the stirring rod during the mixing operation, the stirr...
