Description
Technical Field
The utility model relates to a cardboard production facility, especially a facial tissue formula double facer conveyer belt up.
Background
The double-sided machine in the paperboard production equipment is used for attaching the surface paper and the pit paper to form the corrugated paperboard, wherein in order to improve the capacity and the quality of the corrugated paperboard, the surface paper is preferably preprinted paper with a printing layer on the surface, and the finished corrugated paperboard requires that the surface of the printing layer is not scratched or marked, the preprinted paper and the pit paper are reliably bonded, and the paperboard is flat and does not collapse. However, according to the current paperboard technology, the above problems cannot be overcome simultaneously, for example, when the paperboard is processed by a double-sided machine in a mode that the preprinted paper faces upwards, the surface of the preprinted paper has ink, films and the like, so that the air permeability is blocked, the moisture generated in the process of drying and solidifying the paste inside the corrugated board is difficult to discharge, and the paperboard is not flat or is soft and collapsed. At present, the main mode of solving the problem is to blow or suck air to the side edge of the paperboard towards the direction of the corrugated groove to absorb moisture, but because the width of the paper surface is large, such as 2.8 m wide, and the height of the corrugated groove is only a few millimeters, the moisture in the paperboard which is far away from the edge position is difficult to be discharged, and the final paperboard is uneven (such as the phenomenon that four corners of the common paperboard are tilted upwards).
For this reason, the company has designed a dehumidifying structure, but the dehumidifying structure requires belt cooperation, and thus, a specially structured belt needs to be designed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a simple structure is reasonable, has gas permeability and synchronous drive nature's facial tissue formula for two-sided machine conveyer belt up.
The purpose of the utility model is realized like this:
the utility model provides a facial tissue up formula conveyer belt for double facer, includes the conveyer belt, its characterized in that: the belt surface of the conveying belt is provided with a plurality of air holes, the air holes penetrate through the inner side and the outer side of the belt surface, and the outer side of the belt surface of the conveying belt is an anti-slip surface.
The purpose of the utility model can also adopt the following technical measures to solve:
more specifically, the anti-slip surface is a silicone surface or a rubber surface, but is not limited to the above materials.
As a further scheme, the air holes are circular, and the circular air holes are uniformly stressed and are not easy to crack.
As a further scheme, a plurality of air holes of the conveying belt are distributed in a rectangular array, or the air holes of the conveying belt are distributed in a staggered mode.
As a further scheme, the inner side of the belt surface of the conveyor belt is a wear-resistant low-resistance surface. Because the bottom surface of the conveyor belt may be provided with a negative pressure air suction box, a heating plate and the like, the negative pressure air suction box and the heating plate can be in sliding friction fit with the inner side (back surface) of the belt surface of the conveyor belt, and the wear-resistant low-resistance surface is arranged to effectively prolong the service life of the conveyor belt.
As a further proposal, the wear-resistant low-resistance surface is a nylon belt surface or a canvas belt surface, but is not limited to the above materials.
The utility model has the advantages as follows:
(1) This kind of facial tissue up formula conveyer belt surface for two-sided machine has bleeder vent and antiskid face, and the bleeder vent is favorable to the moisture of the corrugated container board that passes through above that to see through, and the antiskid face forms static friction fit with the back of corrugated container board more easily, makes both synchronous motion, realizes that the transfer process has ventilative effect simultaneously.
(2) The inner side of the conveying belt for the double-sided machine with the upward face paper is a wear-resistant low-resistance surface, and even if a negative-pressure moisture absorption box is arranged close to the inner side of the conveying belt, the negative-pressure moisture absorption box and the wear-resistant low-resistance surface are in sliding friction fit with each other, so that wear cannot be formed in a short period; meanwhile, due to the existence of the negative pressure moisture absorption box, the corrugated board is more beneficial to dehumidification.
