Embodiment 1

[0042] The embodiment of the application discloses a corrugated cardboard production line. refer to figure 1 and figure 2 The corrugated cardboard production line includes base paper frame 1, surface paper preheating wheel, core paper preheating wheel, single corrugating machine 2, triple preheating wheel, pasting machine 3, cardboard forming machine 4, edge trimming machine, and paper cutting machine. Machine 5 and rotary cutting machine 6, the outlet end of rotary cutting machine 6 is also provided with stacking device 7 and conveying device, is provided with humidifying device between cardboard forming machine 4 and trimmer; humidifying device comprises frame 8, frame 8 is fixedly connected with the air cover 9 of the upper and lower end surfaces of the corrugated cardboard. The air cover 9 is a box-shaped one end open and its open end faces the traveling track of the corrugated cardboard. A atomizing nozzle 10 communicated with a high-pressure water source, a plurality ...

Embodiment 2

[0055] The embodiment of the present application discloses a corrugated cardboard production line, referring to Figure 4The difference from Embodiment 1 is that the auxiliary pressing structure includes a baffle 24 fixedly connected to the inner side of the wind shield 9 and arranged along the conveying direction of the corrugated cardboard, the baffle 24 is arranged along the width direction of the corrugated cardboard, and the baffle 24 is free The distance between the end and the inner wall of the air shield 9 gradually increases along the conveying direction of the corrugated cardboard, and the included angle between the baffle plate 24 and the conveying direction of the cardboard is an acute angle.

[0056] When the water mist sprayed by the atomizing nozzle 10 travels in the wind cover 9 along with the air flow driven by the corrugated cardboard, it is gradually approached towards the corrugated cardboard under the step-by-step blocking of a plurality of baffles 24, ther...

Abstract

The invention relates to a corrugated board and a production line thereof. The production line comprises a raw paper frame, a surface paper preheating wheel, a core paper preheating wheel, a single corrugated paper machine, a triple preheating wheel, a pasting machine, a paperboard forming machine, an edge trimmer, a paper cutter and a rotation cut-off machine which are arranged in sequence, and a stacking device and a conveying device are further arranged at the outlet end of the rotation cut-off machine; and a humidifying device is arranged between the paperboard forming machine and the edge trimmer and comprises a rack, fan covers which are arranged on the upper end face and the lower end face of the corrugated board respectively are fixedly connected to the rack, a plurality of atomizing nozzles are arranged at the sides, close to each other, of the two fan covers, and the atomizing nozzles are arranged at the sides, close to the paperboard forming machine, of the fan covers. Mist pumping mechanisms used for pumping residual water mist are arranged at the ends, away from the atomizing nozzles, of the fan covers, and auxiliary pressing structures used for driving the water mist on the inner sides of the fan covers to press the corrugated board in the conveying process are arranged on the fan covers. The production line has the effects that the corrugated board wetting efficiency of the atomizing nozzles is high, the probability that water mist overflows into a workshop is low, and the corrugated paperboard humidifying precision is high.

Description

technical field [0001] The application relates to the field of packaging production equipment, in particular to a corrugated cardboard and a production line thereof. Background technique [0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper interlayer (commonly known as "pit sheet", "corrugated paper", "corrugated core paper", "corrugated core", "corrugated base paper") and a layer Composed of cardboard (also known as "boxboard", "boxboard"), it has high mechanical strength and can withstand collisions and falls during handling. During the production of corrugated cardboard, the moisture content in the cardboard not only seriously affects the hardness and flatness of the cardboard, but also has a certain impact on the subsequent printing, tiling and die-cutting processes. When the moisture is too high, the processed cardboard will be soft, not stiff, and easy to collapse after being boxed; when the moistu...
