Mist spray humidifying device for triple preheating cylinder

Abstract

The invention provides a mist spray humidifying device for a triple preheating cylinder and belongs to the technical field of paper packaging material combined machinery. The triple preheating cylinder comprises a rack, an inner-layer paper preheating cylinder, a corrugated paper preheating cylinder and an outer-layer paper preheating cylinder. An inner-layer paper lead-in roller, a corrugated paper lead-in roller and an outer-layer paper lead-in roller are arranged at one side of the rack, and an inner-layer paper lead-out roller, a corrugated paper lead-out roller and an outer-layer paper lead-out roller are arranged at the other side of the rack. The mist spray humidifying device comprises a support, a spray box, a water pipe and a automatic mist spray mechanism set. The support is fixed on the rack and corresponds to the portion above the inner-layer paper lead-out roller in the length direction of the inner-layer paper lead-out roller. The spray box is fixed on the support. The water pipe is arranged in a box cavity of the spray box and is connected with a water source pipeline. The automatic mist spray mechanism set is connected to the water pipe and is connected with an electrical control cabinet in a controlled mode. The mist spray humidifying device for the triple preheating cylinder guarantees the evenness of the amount of humidification water and avoids the phenomenon that water stains appear on a corrugated board. In addition, the mist spray humidifying device for the triple preheating cylinder can reflect the good automatic effect, relieves the operation intensity of workers, reflects scientificity, and guarantees the quality of the corrugated board.

Description

technical field [0001] The invention belongs to the technical field of composite machinery for paper packaging materials, and in particular relates to a spray humidification device for triple preheating cylinders. Background technique [0002] The triple preheating cylinder mentioned above is also called triple preheating roller, which is mainly used to preheat the corrugated paper, inner layer paper and surface layer paper that constitute the packaging cardboard before entering the compound machine for compounding. Among them, the inner layer paper (also The inner paper) is located on the inward side of the corrugated paper in use, while the surface layer paper (also called face paper) is located on the outward side of the corrugated paper in use. The packaging cardboard of this structure is mainly but not limited to making Various paper packaging boxes. [0003] As known in the industry, paper is highly sensitive to humidity, more precisely, it is picky about humidity. T...

Problems solved by technology

[0003] As known in the industry, paper is highly sensitive to humidity, more precisely, it is picky about humidity. Taking the aforementioned packaging cardboard as an example, the weight of the inner paper is smaller than that of the outer paper. (The corrugated paper is the thickest), therefore, if the inner layer paper is neglected to humidify when it is out of the preheating cylinder and directly enters the laminating machine to compound it with the corrugated paper, then it is very easy to appear warped, brittle, etc., resulting in packaging Defects in cardboard will eventually affect the quality of corrugated packaging boxes, or even be scrapped

[0004] In the prior art, a tool connected with a tap water pipe and equipped with a spray head at the end is generally used to spray the inner layer of paper going out of the preheating cylinder by workers. Although this humidification method can overcome the aforementioned technical problems to a certain extent, There are the following deficiencies: one is that the degree of humidification is difficult to control and the humidification is not uniform, thus leaving water spots on the inner layer of paper, which affects the quality of the packaging cardboard; second, the work intensity of the workers is high; experience, sense of responsibility and even emotional changes, so it is unscientific
