Description

Technical Field

[0001] The utility model relates to the technical field of strapping machines, in particular to a novel temperature control system for the ironing head of a strapping machine. Background Art

[0002] The strapping machine is a commonly used packaging machine, which is mainly used to tie packaging materials into binding belts for bundling and protection of goods. The working principle of the strapping machine is to beat the packaging materials into binding belts through a striking mechanism. The striking mechanism is usually composed of one or more striking plates. When the machine is started, the motor transmits power to the striking mechanism through the reducer and transmission mechanism. The striking plate strikes the packaging material at a certain speed and force to form a binding belt.

[0003] However, the traditional strapping machine has the following disadvantages:

[0004] The hot knife on the traditional strapping machine is adjusted by an old-fashioned potentiometer. By adjusting the output current, the high temperature generated by the heating transformer is applied to the thermocouple to generate heat so that the blade can generate a temperature sufficient to bond two straps. However, this old-fashioned potentiometer often has no protection against overheating, and is frequently replaced every half a month, which is expensive. In addition, it is installed inside the electrical cabinet, so non-maintenance personnel cannot open the inside to check whether it is burned. Maintenance is inconvenient. Utility Model Content
