Multifunctional control circuit with power-off protection function for cloth cutting machine

Abstract

The invention relates to a control circuit of a cloth cutting machine, wherein a relay circuit is used as a core; an analog switch assembly or a logic assembly is adopted to replace relays; a larger-capacity capacitor is arranged at a power supply input position and is used for ensuring that the control circuit continuously works within a short time during power interruption; a starting socket can be in plugging connection with a receiver for a wireless purpose and is started by a remote controller, or the starting socket can also be in direct plugging connection with a starting switch and a counter for usage; after a magnetic switch is in contact with a magnetic block, the circuit is self-locked so that the cloth cutting machine can be prevented from vibration and displacement during lifting and the circuit can be prevented from judging directions falsely; a convertible transmission motor works in a one-way transmission manner and a two-way transmission manner; during cutter sharpening, the control circuit is cut off, a main motor is started independently and can be in plugging connection with the driving circuits of different motors or with a remote controller, and the remote controller is used for controlling the motor driving circuit provided with the receiver; and the control circuit has manual, semi-automatic and full-automatic lifting functions.

Description

technical field [0001] The present invention relates to a controller, in particular to a control circuit of a cloth cutting machine. Background technique [0002] The cloth cutting machine is a machine installed on the cutting bed to cut the cloth. The cloth cutting machine is composed of a cloth cutting machine, a slide rail and two lifting frames. On the slide rail seat of the lifting frame, the cloth cutting machine is placed in the slide rail, the cloth is pulled to the required length through the upper end of the slide rail, the cloth cutting machine cuts off the cloth, and then lifts the lifting frame to press the cut cloth on the slide rail Below, the cut cloth is repeatedly pressed under the slide rail so that the cut cloth is flattened. The cloth cutting machine is divided into manual and fully automatic, including one-way cutting and two-way cutting. Manually install the start switch on the handle of the cloth cutting main machine to start the main motor. After st...

AI Technical Summary

Problems solved by technology

For the controller of the original cloth cutting machine, (1) when the original controller is powered off, the remaining inertia of the moving motor cannot be controlled, and the cloth breaking host directly collides with the end cover of the slide rail, which is easy to damage the cloth breaking host and the slide rail. rail

(2) The original controller, because the controller needs to be in the range of operation, it is easy to touch the controller when the cloth and the slide rail are lifted, causing inconvenience

(3) In the application of the lifting frame of the original cloth cutting machine, two methods are adopted, automatic and manual. When encountering some fabric curling, it needs to be manually used to sweep the cloth manually, and then lower the slide rail to flatten the cloth. , manual is inefficient, and automatic lifting cannot effectively deal with the curling phenomenon

(4) The original controller needs to be pre-set or set before sharpening the knife, which makes the operation complicated and inconvenient to use
