Description

Technical Field

[0001] The utility model relates to the field of glue binding machines, in particular to a fine-tuning mechanism for lifting and lowering a glue spraying device. Background Art

[0002] A small linear wireless binding machine is a device that applies hot melt glue on the spine side of the book core to glue and staple books. The binding machines generally use EVA hot melt glue and PUR hot melt glue. EVA hot melt glue is an ordinary hot melt glue with low cost. The glue after heating and melting will be completely solidified after 24 hours and can be heated and melted again; EVA hot melt glue generally uses an open glue box, and the bound books cannot be opened 180°. PUR hot melt glue is relatively expensive, but has excellent bonding strength and outstanding heat resistance, chemical resistance, corrosion resistance, and aging resistance. The glue layer of the bound books is thin and flexible, and the bound books can be flattened 180°. This glue has been rapidly developed and applied in recent years, but the existing glue binding machine’s spray device is inconvenient to lift and adjust, and the thickness of the book’s glue layer cannot be quickly adjusted according to actual needs, affecting work efficiency.
