Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety protection technology for die-cutting machines, and in particular to an emergency stop device for die-cutting machines. Background Technology
[0002] The emergency stop device of a die-cutting machine is an important safety device used to immediately stop the operation of the equipment in an emergency to ensure the safety of operators and equipment.
[0003] A die-cutting machine is a machine that uses steel blades, metal molds, steel wire, etc., to apply pressure through a printing plate to cut printed materials or cardboard into a certain shape. During the operation of the die-cutting machine, due to improper operation, mechanical failure, or other reasons, an emergency may occur, requiring immediate stopping of the machine to avoid personal injury or equipment damage. However, traditional die-cutting machine emergency stop devices usually use simple push-button emergency stop switches, which have the following shortcomings:
[0004] 1) High error rate: Button-type emergency stop switches are easily accidentally pressed, causing the machine to stop unexpectedly and affecting production efficiency;
[0005] 2) Slow response speed: After discovering an emergency, the operator needs to move their arm to press the button, which involves a certain reaction time and cannot achieve instantaneous shutdown;
[0006] 3) Lack of status indication: Traditional emergency stop switches cannot intuitively display the emergency stop status of the machine, making it difficult for operators to determine whether the machine is in a safe state. Therefore, we have proposed an emergency stop device for die-cutting machines. Utility Model Content

[0017] The back of the housing is provided with a plurality of heat dissipation grids, and the plurality of heat dissipation grids are equidistantly arranged along the length of the housing.
[0018] As an improved technical solution, the emergency stop button is a mushroom-shaped button with a self-locking function, and the emergency stop button has anti-slip texture.
[0019] As an improved technical solution, the infrared sensing module includes an infrared transmitter and an infrared receiver, which are respectively installed on both sides of the dangerous area of the die-cutting machine.
[0020] As an improved technical solution, the control unit adopts a programmable logic controller.
[0021] As an improved technical solution, the audible and visual alarm includes a buzzer and an LED light, both of which are mounted on the top of the housing, with the LED light located on one side of the buzzer.
[0022] As an improved technical solution, the status indicator light uses a tri-color LED light, and is used to indicate normal operation status, warning status and emergency stop status respectively from top to bottom along the height direction of the housing.
[0023] As an improved technical solution, the emergency stop button, the infrared sensing module, the control unit, the audible and visual alarm, and the status indicator light are all connected by cables.
