[0086] In this way, the metal mesh stack can be subjected to multiple steel band bundling operations by the multiple bundling interval controllers 47, and the specific operation process is as follows: when the metal mesh stack is conveyed on the roller conveying support 42, after the front side of the metal mesh stack touches the first bundling interval controller 47, the bundling interval controller 47 controls the roller motor to stop rotating and controls the baling head to work once, at this time, the baling head performs a steel band bundling operation on the metal mesh stack, after the bundling is completed, the roller motor continues to work to drive the conveying roller 43 to rotate to convey the metal mesh stack again, when the metal mesh stack touches the next bundling interval controller 47, the baling head works again to perform the next steel band bundling operation on the metal mesh stack, and the above operation is repeated, so that the baling head can perform multiple steel band bundling operations on the metal mesh stack by the multiple bundling interval controllers 47, which is convenient to use.

[0087] For those skilled in the art, according to the teaching of the present application, the changes, modifications, replacements and variations made to the embodiments without departing from the principles and spirits of the present application still fall within the protection scope of the present application.
