There is enough spaces, the disengaging for body paper between beam 9 and lower straining beam 1.
The functional part of the functional part of preheating and auxiliary preheating is incorporated into a long side space, entirety can be made
Structure tends to be compact, and the space of relative compact, because area of dissipation is small, it is possible to reduce energy consumption.
Preheating cylinder as illustrated in fig. 1 and 2, it is preheating space to remember foregoing rectangular parallelepiped space, builds the support body of preheating space
Part is frame, and its hot cylinder is configured with a pair, and hot cylinder located above is designated as hot cylinder 7, and the hot cylinder being located below is designated as lower heat
Cylinder 5, being different from the existing how hot cylinder configuration for the two-sided preheating of body paper needs the bigger technical conditions of hot cylinder spacing,
In embodiment of the present utility model, the spacing of two hot cylinders is smaller, and its spacing is 10mm or so, is typically chosen 8 ~ 12mm.
Under normal condition, what is considered is that body paper has certain hardness, and hot cylinder spacing is bigger, and part body paper is distributed in
Section is formed between adjacent heat cylinder, when hot cylinder distance is bigger, corner change is smaller here for body paper, it is not easy to damages
Body paper.
It has been recognised by the inventors that after the heating of for example upper hot cylinder 7, body paper possesses certain deformability, this and carton
（Such as film paper lunch-box）It is molded similar, the carton forming scraps of paper have certain plasticity ability after the heating, so as to pass through
During mould molding, it is not easy to produce tear.Although only preheated by the one side of upper hot cylinder 7, it is impossible to heat penetration body paper, but still make original
Paper improves certain deformability, and is not easy to produce folding line.
Two hot cylinder spacing are smaller, then make preheating space relative compact, and reduce area of dissipation.And the less bar of spacing
Under part, although corner produces relatively violent change, this change does not interfere with body paper plane quality.
In addition, may be less likely to caused negative effect to improve two hot cylinder spacing, two hot cylinder individual specifications are different, upper heat
Cylinder 7 relatively under hot cylinder 5 it is big, determined from assembly method, upper hot cylinder 7 is flatly assemblied in the middle and upper part of preheating space, occupies larger
Space, lower hot cylinder 5 is configured in the bottom of preheating space because its individual is relatively small.
The upper individual of hot cylinder 7 is relatively large, and when being transitioned into lower hot cylinder 5 by less spacing, corner change is relatively gentle.
Further configuration be then the axis of axis and the upper hot cylinder 7 of lower hot cylinder 5 in same vertical plane, although between upper
Body paper part between hot cylinder 7 and lower hot cylinder 5 is smaller, so will necessarily also increase cornerite of the body paper on corresponding hot cylinder, it is related to
The problem of two aspects, one is cornerite becomes big, the contact area of hot cylinder and body paper becomes big, is advantageous to improve the pre- thermal efficiency and heat
It is, although two hot cylinder spacing are smaller, because the lower hot diameter of cylinder 5 is relatively small, to be produced the problem of another aspect using proportion
The change of raw corner is not violent.
Further, it is contemplated that the utilization of the energy, lower hot cylinder 5 is relatively small, the not as above hot cylinder, but such as preceding institute of the heating to body paper
State, upper hot cylinder 7 is heated to be single-side heating, but body paper has certain heat-transfer capability, and two hot cylinder spacing are smaller, heat
Scatter and disappear smaller, under the conditions of lower hot cylinder 5 is less, still there is preferable two-sided pre- heat effect.Generally speaking, energy consumption is smaller.
It was paper gap to write down the space stayed between hot cylinder 5 and upper hot cylinder 7, and body paper passed through paper after upper hot cylinder 5 comes
Gap surrounds on lower hot cylinder 5.
Further configuration also includes, there is provided a feed roller, upper roller 8 as shown in Figure 1, its both ends is installed by bearing
Upper rack and the side for being located at upper hot cylinder 7, for adjusting the entering angle of body paper, its installation site also determines body paper in upper heat
Cornerite on cylinder 7.
One discharge roller is provided, lower roll 2 as shown in Figure 1, frame lower is installed in and is located at the lower hot side of cylinder 5,
Body paper determines the direction that discharges after the lower hot discharging of cylinder 5 by discharge roller.
Wherein, upper hot cylinder 7 and lower hot cylinder 5 are arranged in frame by bearing, so as to around the revolution of respective axis
The free degree.
Referring to accompanying drawing 1, body paper is passed around to the upside of upper hot cylinder 7 from the downside of upper roller 8, from upper hot cylinder 7 after upper hot cylinder 7
The paper gap of crossing stayed between lower hot cylinder 5 passes, and then detours on lower hot cylinder 5, then be exported by lower roll 2.
It is visible in the structure shown in Fig. 2, only it is the upper hot configuration driven device of cylinder 7, without for the lower hot configuration driven of cylinder 5
Device, lower hot cylinder 5 are in a kind of driven state based on the friction with body paper, and body paper plays certain V belt translation effect, Ke Yijian
Change overall driving to set.
And in the present embodiment, because two hot cylinders are apart from closer, cornerite of the body paper on corresponding hot cylinder can be caused to become
Greatly, be advantageous to improve transmission capacity, i.e., under the effect that is driven by body paper of hot cylinder 5 it is relatively good.

Left end, the gyroaxis of upper hot cylinder 7 is drawn from the left end of bearing block 6, for introducing the power of drive device.
In the construction shown in fig. 1, the drive device is driven using chain-drive mechanism, because hot cylinder is to transmission essence
Spend less demanding, tape handler can also be used, directly can also directly be exported using motor reducer.
Motor 3 be engine, it is necessary to be slowed down by reductor, reductor is typically gear train, possesses certain turn
Fast fan-out capability.If motor 3 is configured into variable-frequency motor, different speed can be exported according to different body paper, so as to
Speed can be set up to be adapted to required pre-heat effect.
Determined by experiment, the diameter ratio of upper hot cylinder 7 and lower hot cylinder 5 is 7:3 be optimal proportioning, and body paper is from upper hot cylinder 7
After mistake paper gap between lower hot cylinder 5 passes, it is wrapped on lower hot cylinder 5, under conditions of the lower hot individual of cylinder 5 is relatively small,
Remain able to obtain relatively large cornerite, so as to relatively good pre-heat effect.
From in CN106956471A, cornerite of the body paper on each Corrugator roller is little, Corrugator roller ratio can be caused
Larger heating surface (area) (HS is directly exposed in air, in embodiment of the present utility model, then can effectively overcome this to lack
Fall into.
In order to further increase cornerite, the right side shown in body paper from Fig. 2 enters, and is passed from left side, correspondingly, upper roller 8 is set
Put and the left side of corresponding wallboard in fig. 2 is set in the right side of corresponding wallboard as shown in Figure 2, lower roll 2.
But, found by experiment, under conditions of two hot cylinder spacing are relatively small, upper roller 8 as shown in Figure 1 is with
Roller 2 remains able to obtain preferable pre-heat effect under conditions of wallboard homonymy.Also, both can be further dropped in homonymy
The energy consumption of low drive device（Lower hot cylinder 5 is driven）, more excellent selection is the axis of discharge roller and feed roller in same vertical plane
On.
The diameter of feed roller is more than the diameter of discharge roller, and the factor considered is that hardness is larger, tough before body paper is not heated
Property is poor, and feed roller is relatively large, it is not easy to drawing crack body paper.
Comparatively, either feed roller or discharge roller, its diameter are much smaller than the diameter of upper hot cylinder 7 and lower hot cylinder 5,
Different from the prior art, modified roller needs the larger diameter that compares, in embodiment of the present utility model, discharge roller and enter
Material roller is served only for determining input and output material direction, rather than the correction of body paper shape.Simply upper hot cylinder 5 is straight for the roll neck of usual feed roller
/ 9th or so of footpath.
