[0002] Automatic baling machines can realize automatic baling. The principle is to wrap the product or package with plastic strapping tape, tighten it and connect the two ends by melting through thermal effect. The function of the baling machine is to make the plastic strapping tape close to the surface of the package to be tied, so as to ensure that the package will not fall apart during transportation and storage due to loose strapping, and at the same time, the strapping should be neat and beautiful.

[0003] For safety reasons, a safety fence is set up around the automatic baler of the continuous casting unit of cast aluminum ingots to prevent abnormal entry of personnel. However, when necessary, personnel will enter the safety fence to manually replace the steel belt and temporarily handle some faults. Due to the high efficiency and high speed of the automatic baler, after a fault occurs, the operator has a fluke mentality in order to handle the fault as soon as possible without setting up a guardian, and may forget to suspend the work of the automatic baler, which is prone to safety accidents.

[0004] At present, the safety fence of the automatic baler of the aluminum ingot continuous casting unit in the foundry workshop has been found to have certain safety hazards during operation. Although there is a safety fence around the automatic baler to separate the operator from the automatic baler, and a small door is left for the operator to replace the steel belt and the maintenance personnel to perform maintenance, the automatic baler cannot effectively prevent people from entering and exiting during work, and safety accidents may occur. Therefore, it is necessary to propose a protective fence for the aluminum ingot casting workshop to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a protective fence for an aluminum ingot casting workshop, which has an "automatic" safety interlocking device that enables an automatic switch and a limit switch to form a device.
