Indentation equipment suitable for corrugated boards with different thicknesses

Abstract

The invention discloses indentation equipment suitable for corrugated boards with the different thicknesses. A conveying device is used for conveying the corrugated boards from top to bottom and turning over the corrugated boards by 180 degrees in the conveying process, so that the corrugated boards are turned over from the upward film covering face to the upward indentation face, and the corrugated boards are conveyed to an indentation station; and a gluing device and a film covering device are used for conducting gluing and film covering on the corrugated boards in the turnover process of the corrugated boards. The conveying device comprises a conveying roller, a plurality of guide wheels and a plurality of conveying belts; the outer diameter of the conveying roller is adjustable; and a gap used for clamping the corrugated boards is formed between the conveying belts and the conveying roller, a paperboard inlet and a paperboard outlet are formed in a matched manner, and an indentation device is located on the downstream of the paperboard outlet and comprises an indentation wheel capable of being close to or away from the conveying belt at the paperboard outlet. According to the indentation equipment, the compressive strength of the indentation parts of the corrugated boards is improved, rapid indentation processing of the corrugated boards is achieved, and the indentation equipment is high in automation degree.

Description

technical field

[0001] The invention relates to the field of cardboard processing, in particular to a creasing device suitable for corrugated cardboards of different thicknesses. 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 cor...

Examples

Embodiment 1

[0035] 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 .

[0036] 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.

[0037] In order to facilitate the subsequent desc...

Embodiment 2

[0065] 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 Example 1 is that the cardboard creasing equipment in this example has adjusted the structure of the conveying device, and the structures of the paper feeding device 2, gluing device 4, film coating device 8 and creasing device 5 are the same as those in the embodiment 1 is exactly the same, to save space, it will not be introduced here.

[0066] 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 .

[0067] 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 c...
