Abstract
The invention discloses a method and a device for preventing a steel belt of a gumming machine from being on a fire. Firstly, a roller capable of rolling on the steel belt is arranged on the steel belt of the gumming machine; a metal induction sheet is arranged on the roller; a proximity switch is arranged on a bracket with the roller; the roller normally rolls on the steel belt when the steel belt normally runs; the proximity switch detects rotation of the roller; a high-frequency heater normally works; the proximity switch does not detect rotation of the roller when the steel belt stops moving forwards due to a fault, then emits a signal to a high-frequency fire alarm circuit, and controls and cuts off a control power supply of the high-frequency heater; the high-frequency heater stops working; and the alarm device begins to alarm at the same time. In the manner, glue solution on the steel belt after stopping can be prevented from being on fire due to over-high temperature. The device disclosed by the invention has the advantages of being simple in structure, safe and reliable, ingenious in design, and low in equipment cost; the personal safety of the staff is improved; and use of a fire extinguisher and a fire hazard are reduced.
