Problems solved by technology

[0004] However, the inventors found that this equipment has the following problems: firstly, in the production process of corrugated paper, especially in the production process of multi-layer corrugated paper, it only has the ability to preheat the corrugated paper at the bottom, and the contact between the middle preheating plate leads to insufficient preheating , the upper and lower layers of moisture are uneven and easy to warp. In addition, this equipment can only preheat the face paper before bonding when using roll continuous face paper for production. When using single-sheet face paper, it is difficult to realize single-sheet Preheat a single sheet of facial paper

Embodiment 1

[0071] Such as figure 2 , image 3 , Image 6 , Figure 7 , Figure 8 with Figure 9 As shown, a continuous output type single facial paper preheating mechanism includes a facial paper feeding device 1 for continuously conveying a single facial paper to the first paper inlet 10, and also includes a facial paper feeding device 1 arranged at the facial paper feeding The facial tissue preheating device 5 at the rear of the device 1, the facial tissue preheating device 5 includes a conveyor belt a51 and a preheating mechanism 52 arranged below the conveyor belt a51, and there is a space between the conveyor belt a51 and the preheating mechanism 52. Single facial paper 103 is transported to the preheating channel 100 for preheating, and the transmission belt a51 is divided into a section 200, b section 300 and c section 400, and when the single facial paper 103 is in a section 200, it is between the transmission belt a51 The space is relatively stationary and driven by the tr...

Embodiment 2

[0080] Components that are the same as or corresponding to those in the first embodiment use the reference numerals corresponding to those in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that in this embodiment, the transmission belt a51 is made of silica gel material, the friction force between the transmission belt a51 and the face paper is f1, and the face paper and the preheated The friction force between the mechanisms 52 is f2, f1 and f2 are satisfied, f1>f2≥0, the transmission speed of the transmission belt a51 is v, and v1, f1 and f2 meet the requirements of the transmission belt a51 to drive the facial paper transmission During the process, the face paper and the conveyor belt a51 remain relatively still.

[0081] It should be noted that the transmission belt a51 is not limited to be made of the silica gel material described...

Embodiment 3

[0083] Such as figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Figure 9 with Figure 10 As shown, a three-layer corrugated cardboard production line also includes a second paper inlet 20 behind the first paper inlet 10, a first first corrugated paper 101 that is used to transport the glued first corrugated paper 101 to the second paper inlet 20. The corrugated paper conveying device 2 and the bonding device 3 for bonding the single face paper 103 and the first corrugated paper 101 to form a three-layer corrugated board 104 .

[0084] Specifically, the first corrugated paper conveying device 2 includes a gluing assembly a21 for gluing the first corrugated paper 101 and a preheating assembly arranged behind the gluing assembly a21 for preheating the first corrugated paper 101 a22.

[0085] Further, the first corrugated paper conveying device 2 also includes a deviation correcting component a23 for correcting the deviation of the first ...

Abstract

The invention relates to a single-sheet surface paper preheating mechanism, corrugated paper board production lines and process and a control method. The single-sheet surface paper preheating mechanism comprises a surface paper feeding device for continuously conveying single-sheet surface paper to a first paper feeding part, and further comprises a surface paper preheating device arranged behindthe surface paper feeding device. The surface paper preheating device comprises a conveying belt a and a preheating mechanism body arranged below the conveying belt a. A preheating channel for conveying and preheating of the single-sheet surface paper is reserved between the conveying belt a and the preheating mechanism body. The conveying belt a is divided into a section a, a section b and a section c, when the single-sheet surface paper is located at the section a, the single-sheet surface paper and the conveying belt a are relatively static, and under driving of the conveying belt a, the front and rear single-sheet surface paper are backwards conveyed in an end-to-end connected mode. The preheating mechanism body is arranged along the conveying path of the single-sheet surface paper andpreheats the single-sheet surface paper in the single-sheet surface paper conveying process. The problems that when the surface paper and corrugated paper simultaneously enter drying equipment, the surface paper is located at the upper portion and cannot be fully dried, and preheating and continuous conveying of the single-sheet surface paper cannot be simultaneously conducted are solved.

Description

technical field [0001] The invention relates to the technical field of corrugated cardboard production equipment, in particular to a preheating mechanism for a single face paper, a corrugated cardboard production line, a process and a control method. Background technique [0002] In the prior art, when producing corrugated cardboard, the base paper is usually first pressed into corrugated paper, bonded with the base paper to form a single-sided corrugated cardboard, and then glued on the corrugated board and pasted with the face paper to form a three-layer corrugated cardboard. , Or add a set of single-sided corrugated cardboard forming equipment, and then bond to form five layers of corrugated cardboard or even seven layers. [0003] A Chinese invention patent with the authorized notification number CN102173162B, which discloses a production method and production line of pre-printed corrugated cardboard, which solves the problem that the existing corrugated cardboard produc...
