Problems solved by technology

[0003] The patent application number is 2018108863318, which discloses a new type of cardboard surface indentation device. Sticking transparent tape on one side of the corrugated cardboard and indenting on the other side can enhance the compressive strength of the indented part of the corrugated cardboard. However, the device still has the following deficiencies : (1) Only one piece of corrugated cardboard can be indented at a time, the processing efficiency is low, and it is not suitable for batch corrugated cardboard indentation processing; (2) It is necessary to manually feed and unload corrugated cardboard, and the It is necessary to manually draw the scotch tape to or separate the corrugated cardboard before and after the mark, which has high labor intensity and low degree of automation

Embodiment 1

[0042] refer to figure 1 , 7 , the cardboard creasing equipment of this embodiment is used to process one or more creasing on the corrugated cardboard 101 (sheet). The cardboard creasing device in this embodiment includes a frame 7 , a paper feeding device 2 installed on the frame 7 , a conveying device 3 , a glue applying device 4 , a film covering device 8 and a creasing device 5 .

[0043] refer to figure 1 , the paper feeding device 2 is installed on the top of the frame 7, and is used to send out the corrugated cardboard 101 one by one and send it to the conveying device 3 at a constant conveying speed. refer to Figure 4 and 5 , the paper feeding device 2 includes a plurality of beams 29 and a plurality of push blocks 25, the beams 29 are loaded with corrugated cardboard 101 in the form of a pile, and the push block 25 is used to push the corrugated cardboard 101 in the lower layer of the pile Push out one by one.

[0044] In order to facilitate the subsequent desc...

Embodiment 2

[0072] figure 2 It is a structural schematic diagram of the cardboard creasing equipment of the modified example, figure 2 The cardboard creasing machine shown is suitable for creasing cardboard of different thicknesses. The difference from Embodiment 1 is that the cardboard creasing equipment in this embodiment has adjusted the conveying device 3, and the structures of the paper feeding device 2, gluing device 4, film coating device 8 and creasing device 5 are the same as in Embodiment 1. are exactly the same in , and will not be introduced here to save space.

[0073] The conveying device 3 in this embodiment further includes a second paper supply belt 23 and a position adjustment mechanism for adjusting the height position of the second paper supply belt 23 .

[0074] The second paper supply belt 23 is located between the first paper supply belt 22 and the conveying roller 1 , and its position is adjustable in height, and is used to receive the corrugated cardboard 101 ...

Abstract

The invention provides a creasing method and equipment for corrugated boards. The creasing method comprises the following steps that the corrugated boards are conveyed one by one at a constant speed; the corrugated boards are turned over from top to bottom, glue spreading and film covering are sequentially carried out on the film covering surfaces of the corrugated boards in the turning-over process, the corrugated boards are finally turned over by 180 degrees, and the mode that the film covering surfaces face upwards is changed into the mode that the creasing surfaces face upwards; continuous creasing lines are processed on the creasing surfaces of the corrugated boards; and the paperboards subjected to creasing processing are stacked. According to the creasing method, the compressive strength of the creasing parts of the corrugated boards is improved, rapid creasing processing of the corrugated boards is achieved, the degree of automation of the creasing equipment is high, frequent carrying of the corrugated boards is not needed, the labor intensity is reduced, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to the field of cardboard processing, in particular to a creasing method and creasing equipment for corrugated cardboard. Background technique [0002] The corrugated cardboard can be folded into a corrugated box by die-cutting the corrugated cardboard and unfolding it into a predetermined shape, then creasing the corrugated cardboard at an appropriate position, and then turning the corrugated cardboard along the pressed creasing line. At present, during the use of corrugated cardboard boxes, damage to the indentation of the corrugated cardboard often occurs. The reason is that the strength of the indented part of the corrugated cardboard is low, and the indented part is prone to crushing due to the pressure of the objects in the box for a long time. In order to solve the problem of insufficient strength of the indented part of the corrugated cardboard, it may be considered to paste a strip of film or paper at the corresponding p...
