Description
Technical field
Corrugated case production equipment technology is the utility model is related to, is erected more particularly to a kind of interchangeable corrugated case
Line creasing roller structure.
Background technology
The crease line of corrugated case production（Vertical line and horizontal line）It is suppressed with following several ways：
1. crease line is often referred to horizontal line ball rolling cover crease line 1-5 as shown in Figure 1, perpendicular line ball the first length and width folding as shown in Figure 1
Trace line 1-1, the second length and width crease line 1-2, and when horizontal line ball 1-5 is generally produced on corrugated paper board production line rip cutting marking press just
It has been completed that, erecting line ball 1-1,1-2 needs in full-automatic printing groove（Die-cutting machine）Upper compacting forms, and the line ball mode has two
Kind：
1）As shown in Figures 1 to 4, a kind of mode is to complete perpendicular pressure using pre- pinch roller 5-9 and fabric wheel 5-12 in slotted unit
The compacting work of line；
2）Another way is to be formed in die cutting unit 6 with die cutting plate compacting；
The no matter any mode of above-mentioned line ball, general corrugated board is on length L directions（Such as Fig. 1）Allowance is not stayed,
Paper feed required precision thus to corrugated board on the flatness of cardboard, printing machine is high, otherwise easily occurs walking causing size inclined
Difference and scrap；
2. vertical line is suppressed to use to roll on a set of die cutting plate in die cutting unit 6 simultaneously with horizontal line and formed, the technique typically exists
The surrounding of corrugated board leaves allowance, thus increases cost；
According to above-mentioned corrugated board in full-automatic printing groove（Cross cutting）Indentation line rolling principle on machine, with five layers of corrugated paper
Exemplified by case, pre- pinch roller and the fabric wheel rolling principle as shown in Figure 25,26, due to the facial tissue of corrugated board in actual production（Such as Fig. 2
Middle 1-4）With inner paper（Such as 1-3 in Fig. 2）Material, moisture, flatness, the reason such as the pressure depth and the stupefied shape height of corrugated board
Selection and configuration, face（In）Layer paper quality is arranged in pairs or groups with stupefied shape, and unreasonable, line ball Alignment Design is unreasonable（Such as 5-9 in Fig. 4 to 18
With 5-2,5-12 and 5-13）Paper 1-3 or facial tissue 1-4 bursts at line ball in often occurring rolling indentation line afterwards etc. factor,
Here it is one of quick-fried line phenomenon of usually said corrugated case（Hereinafter referred to as quick-fried line）；The phenomenon often occurs, especially vertical line
Quick-fried line phenomenon, thus it is careful or inevitable when employee's operation；For vertical line line ball, as shown in Figure 4 generally

Dress and replacing；Pre- the pinch roller 5-9 and fabric wheel 5-12 of existing equipment configuration simultaneously are generally just a kind of linear, if for owning
3rd, five, seven layers and corrugated case rolling of the unlike material with material, are to have very much limitation：For example tri-wall corrugated paper case is general
Thickness 4mm or so, five layer paperboard thickness 7mm or so, seven layer paperboard thickness are all with constant precompressed close to 12mm or so
Three ply board carton corner corrugation after line ball is molded will certainly be caused to destroy if wheel 5-9 and fabric wheel 5-12 rolling vertical lines serious
And the compression strength of corrugated case is influenceed, while corner forming angle is not straight, and seven layers of corrugated sheet use pre- the pinch roller 5-9 and line ball
It is narrower to occur that nexine corrugation destroys for corrugated case corner after wheel 5-12 rollings, occurs the inside support after shaping and causes face
Line is not straight after the quick-fried line of paper or the shallow folding line of vertical line line ball or rolling curve（Impression line position and folding line line position are inconsistent）Phenomenon,
Shaping and the compression strength of corrugated case can be influenceed.
