Description

Technical Field

[0001] The utility model relates to the technical field of cardboard production and processing, in particular to a punching device for cardboard production. Background Art

[0002] Cardboard is a thick paper sheet made from various pulps with fibers interwoven with each other. During the production and processing of cardboard, in order to meet the needs of different products, it is often necessary to drill holes on the surface of the cardboard. However, although the cardboard has a certain thickness, it is still easy to deform and bend under pressure.

[0003] At present, drilling holes in cardboard is usually completed by moving a punching machine up and down, but this will cause local pressure on the cardboard at the drilling position. If the surrounding cardboard is not compacted, the cardboard will bend and deform, affecting its appearance and practicality. At present, adjusting the drilling position of the cardboard usually requires manual work to stabilize the cardboard. If the staff makes an operating error, it is very easy to cause injuries.

[0004] In order to solve the above problems, we have made improvements and proposed a punching device for cardboard production. Utility Model Content
