Safe power-off system of tobacco primary processing equipment

Abstract

The invention provides a safe power-off system of tobacco primary processing equipment. The system comprises a control power supply, a dynamic power supply, a contactor, a control power switch and a dynamic power switch, wherein the contactor and the control power switch are arranged in parallel, an output end of the control power switch is connected with a control end of the dynamic power switch,an input end of the control power switch is connected with the control power supply, an input end of the dynamic power switch is connected with the dynamic power supply, and an output end of the dynamic power switch is connected with a power end of the tobacco primary processing equipment. Through the system, the problem that according to existing tobacco equipment, equipment cooling requires a long time after production is over, the situation that an operator performs power-off directly is prone to occurrence, and consequently the equipment cannot be cooled according to set time is solved, and the intelligence and safety of equipment power supply can be improved.

Description

technical field [0001] The invention relates to the technical field of tobacco equipment protection, in particular to a safety power-off system for tobacco shredded equipment. Background technique [0002] There are many processes in the tobacco processing process that use heat energy to process tobacco. Therefore, most of the key equipment for tobacco silk production is equipment with heating function. In order to ensure good performance, these equipment need to be gradually cooled to a safe shutdown condition after use. Power off. Due to the long cooling time of the equipment after production (30-60 minutes), the operator often skips this step and directly cuts off the power to leave work, causing heat to accumulate in the equipment and cannot be dissipated quickly, which will have adverse effects on the equipment over time, such as cracks in key components Leakage, collapse of the firewall, burnout of the stove head, aging and damage of electrical components, etc., not on...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a safe power-off system for tobacco shredded equipment, which solves the problem that the existing tobacco equipment takes a long time to cool down after the end of production, and is prone to the problem that the equipment cannot be cooled according to the set time due to direct power-off by the operator, and can improve The intelligence and safety of equipment power supply can improve the service life of equipment
