Description

Technical Field

[0001] The utility model relates to the technical field of folder gluers, in particular to a folder gluer pressure curing device with a pressure regulating function. Background Art

[0002] Paper box manufacturing generally involves placing the printed cardboard in a die-cutting device for die-cutting, then folding the die-cut cardboard into shape and gluing them together. With the development of technological manufacturing, machine box gluing has replaced manual box gluing, reducing labor costs and improving efficiency.

[0003] At present, the pressure-applying and curing mechanism of the folder-gluing machine generally adopts a cylinder structure to apply pressure to the bonding part of the paper box to make the glue and the paper surface bond together. In order to reduce costs, the printing workshop of a large printing factory uniformly supplies the air source required by each work unit in the workshop with a large air pump device. Therefore, the telescopic cylinder of the pressure-applying and curing mechanism of the folder-gluing machine is generally connected to the large air pump through an air pipe for air supply to work. During use, during peak working hours, due to the simultaneous supply of air to multiple work units, unstable air pressure is prone to occur. In addition, the air supply pipeline is too long and may be bent, which may easily affect the air supply pressure, resulting in the pressure force failing to reach the pressure required for the paper box bonding, causing unstable bonding of the paper box and the appearance of a large number of defective products, which not only reduces production efficiency, but also greatly increases the production cost of the enterprise.
