Description

TECHNICAL FIELD

[0001] The utility model relates to corrugated board production technical field, concretely relates to a kind of even air drying's corrugated board production with air drying device. BACKGROUND

[0002] In the production process of corrugated board, air drying is a crucial link. However, the existing corrugated board production air drying device generally faces a key problem: the position of the air supply device is mostly fixed, and it is difficult to adjust according to actual needs. This design limitation leads to uneven air drying of corrugated board on the conveying belt in actual operation.

[0003] Specifically, since the air supply device is fixed in position, the direction and intensity of the air flow generated by it often cannot be completely evenly covered when the corrugated board passes through. This may result in some areas of the board being over-dried, while other areas being under-dried. Over-drying may make the board brittle and even crack, while under-drying may affect the strength and stability of the board, thus affecting its subsequent processing and use.

[0004] Chinese patent publication No. CN218523887U is a swing type air drying device for corrugated board production. It clamps the corrugated board by setting a clamping part. The translation drive device drives the moving plate to move. The movement of the moving plate drives the rotation shaft to move. The rotation shaft moves while the gear and rack are set to rotate the rotation shaft. The rotation of the rotation shaft drives the paperboard to reverse through the clamping part, so that the fan can more conveniently dry the paperboard, effectively reducing the labor intensity of workers and improving the efficiency of air drying.

[0005] The above structure has certain limitations in actual use; when the width of the corrugated board workpiece to be dried changes, it is difficult to ensure that the air flow can evenly cover the entire workpiece surface due to the fixed position of the air supply device. For narrower workpieces, the air flow may be too concentrated, causing local over-drying; for wider workpieces, some areas may not be dried enough. This not only affects the quality of the corrugated board, but also may cause problems in the subsequent processing process, such as cutting difficulty, poor printing effect, etc. UTILITY MODEL CONTENTS
