Problems solved by technology

[0004] However, at present, it is difficult to control the amount of water when spraying water on the cardboard. Too much water will cause the cardboard to rot; and the sprayed water is easy to splash and flow to other positions, thereby wetting other positions at the indentation. damage the quality of the cardboard

Embodiment

[0023] The embodiment is basically as follows:

[0024] A creasing machine such as figure 1 As shown, it includes a frame 1 and an upper creasing knife 20 for creasing. A pressure cylinder 21 is fixed on the frame 1 , and the upper creasing knife 20 is fixed on the output shaft of the pressure cylinder 21 .

[0025] The frame 1 is slidably connected with a slide table 40 through a slide bar, and the slide table 40 can slide horizontally on the frame 1 . The upper surface of the slide table 40 is hinged with a first discharge plate 31 and a second discharge plate 32, and the hinges of the first discharge plate 31, the second discharge plate 32 and the slide table 40 are arranged oppositely, the first The upper surfaces of the discharge plate 31 and the second discharge plate 32 are flush. An indentation groove 90 is formed between the adjacent ends of the first discharge plate 31 and the second discharge plate 32 , and the indentation groove 90 is located directly below the u...

Abstract

The invention relates to the technical field of paper product machining equipment, in particular to an indenting machine. The indenting machine comprises a machine frame and an upper indenting cutterused for indenting, and further comprises a first releasing plate and a second releasing plate which are connected with the machine frame; an indenting groove is formed between the first releasing plate and the second releasing plate and located below the upper indenting cutter; an elastic hose is arranged in the indenting groove and provided with a plurality of vapor outlets, and water vapor is injected into the elastic hose; the first releasing plate and the second releasing plate can be folded and are hinged to a slide table; and a lower indenting cutter is arranged in the indenting groove,slidably connected with the slide table and connected to a driving device. According to the indenting machine, a paperboard is wetted through the water vapor, the lower indenting cutter extrudes theindented back surface preliminarily, indentations are generated on the indented back surface so that tension can be reduced, indenting is conducted in the releasing plate folding mode, the problem that in the prior art, water sprayed during paperboard indenting is prone to splashing and flowing is solved, cracking of the back surface of the paperboard is prevented, and the indenting quality is improved.

Description

technical field [0001] The invention relates to the technical field of paper product processing equipment, in particular to a creasing machine. Background technique [0002] In the production of paper packaging boxes, the cardboard needs to be indented after printing. After the cardboard is indented, it is easy to fold into a packaging box. The existing indentation technology all uses an indentation knife to press the indentation of the cardboard into a groove, thereby forming an extrusion to generate an indentation. [0003] During the indentation process, the back of the indentation is easy to crack, especially in dry weather, and some cardboard is more brittle and easier to crack. At this time, water needs to be sprayed on the cardboard during the creasing to increase the water content of the cardboard and make it slightly more flexible. [0004] However, at present, it is difficult to control the amount of water when spraying water on the cardboard. Too much water will...
