Description

Technical Field

[0001] The utility model relates to an improvement of a drying device of a corrugating machine, in particular to a drying component laminating and feeding device. Background Art

[0002] Corrugated machine is a device used to produce corrugated paper. Corrugated paper is mainly used as the middle support layer of cardboard and has good structural strength. Corrugated paper can be directly combined with other papers on the equipment to form the required cardboard structure. By combining different layers of paper and drying them in a drying device, an integrated cardboard structure is finally formed. Due to the large size of the drying roller, the paper is prone to uneven fit when passing through the drying roller, resulting in different local temperatures. Therefore, there will be uneven fit, bubbles and other defects, so improvements are needed. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned shortcomings in the prior art and to provide a drying component laminating paper feeding device.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: a drying component includes a drying roller, a roller driving device, a laminating guide belt, a guide belt driving device, and a guide belt tensioning device; the drying roller is driven to rotate by the roller driving device; the portion near the drying roller and the corrugated component is set as a paper feed end; the laminating guide belt is set to be laminating to the surface of the drying roller, and takes the paper feed end as a starting point to surround an arc surface of not less than 270° and a paper discharge end is set at the end; the laminating guide belt is folded back at the paper discharge end and returns to the paper feed end through the guide roller, and forms a circulating working structure; the guide belt drives the guide roller to drive the laminating guide belt to circulate; a guide belt tensioning device is set on the folding path of the laminating guide belt; the guide belt tensioning device applies tension to the surface of the guide belt to tighten the surface of the laminating guide belt. The drying roller is the main drying and heating device. In order to improve the lamination degree, a lamination guide belt is set. The lamination guide belt works in a cycle. The dried cardboard is clamped and dried between the lamination guide belt and the drying roller. The lamination effect is uniform and it is tensioned with the guide belt device. It is suitable for paper of different thicknesses and effectively improves the drying efficiency.

[0005] Furthermore, the guide belt tensioning device includes a sliding rail, a moving block, an adjusting screw, a screw-connecting frame and a tensioning roller. The sliding rail is fixed on the equipment frame. The moving block moves on the sliding rail in the direction of applying tensioning force. A tensioning roller is arranged on the moving block. The tensioning roller is in tight contact with the fitting guide belt. The adjusting screw is screwed on the moving block and screwed on the screw-connecting frame. The screw-connecting frame is fixed on the equipment frame. The adjusting screw rotates to change the relative position of the moving block and the tensioning force. The tensioning force is adjusted by tightening the adjusting screw, and the fitting guide belt is directly tensioned. The adjustment effect is direct and significant. The tensioning is achieved by the tensioning roller, and the tension can be evenly applied to the entire width.

[0006] Furthermore, the laminating guide belt is a cotton webbing, and its width corresponds to the width of the drying roller. The cotton webbing can achieve the effect of heat preservation, reduce heat loss, and the thermal expansion and contraction of the cotton webbing is not obvious, avoiding excessive tension due to temperature differences.

[0007] Furthermore, the roller drive device and the guide belt drive device are both fixed to the outside of the equipment frame through a bracket, and the driving force is output in linkage through a synchronous belt. The drive devices are both externally located on the side of the equipment frame, which is convenient for the inspection and maintenance of the power structure, and can be managed independently to avoid structural interference.

[0008] Furthermore, a bottom paper guide device is provided below the drying roller, and the bottom paper guide device includes a paper feed guide roller and a steering guide roller, the paper feed guide roller is provided near the paper feed end, and the steering guide roller is provided at the lower part of the frame, the bottom paper enters from the lower part of the frame and is turned to the paper feed guide roller through the steering guide roller, and enters the processing gap between the laminating guide belt and the drying roller. The bottom paper is the outer flat paper of the cardboard, and is directly guided to enter under the drying roller for laminating, eliminating other guide structures, saving the conveying distance of the bottom paper, and effectively utilizing the structural space.

[0009] Compared with the prior art, the utility model has the following advantages and effects: the design is an improvement on the paper feeding device of the drying component of the corrugator, which can effectively improve the flatness of paper lamination, reduce defects such as hollowing in the formed paper, and improve the surface flatness of the finished paper, which is suitable for the needs of high printing quality and improves product quality.
