Automatic conveying system adopted between press polishing procedure and drying procedure of fiberboard

Abstract

The invention relates to the technical field of production of special type fiberboards, in particular to an automatic conveying system adopted between the press polishing procedure and the drying procedure of the fiberboard. The automatic conveying system comprises a half-dry press-polishing machine, a first conveyer belt, a second conveyer belt, a third conveyer belt, a fourth conveyer belt and an air suction device, wherein the half-dry press-polishing machine, the first conveyer belt, the second conveyer belt, the third conveyer belt, the fourth conveyer belt and the air suction device aresequentially connected. The first conveyer belt is adjusted by a conveyer belt adjusting device to convey the fiberboards to the second conveyer belt or the third conveyer belt or the fourth conveyerbelt, so that after being discharged from the half-dry press-polishing machine, the fiberboards are respectively conveyed into three drying rooms of a dryer to be dried, a divergent conveyance effectis achieved, so that the structure of the conveying system is simplified, and installation space is saved. The air suction device absorbs and exhausts moisture contained in the fiberboards which comeout from the half-dry press-polishing machine and carry hot air and moisture, so that dissipation of the moisture in the fiberboards is accelerated, and the drying time of the fiberboards in a next dryer is shorter; and therefore, the consumption of heat energy is reduced, and the follow-up drying efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of special fiberboard production, in particular to an automatic conveying system used between the calendering and drying processes of the fiberboard. Background technique [0002] At this stage, the production mode of high-density fiberboard mostly adopts intermittent production, including multiple processes such as wet plate palletizing, water pressing, conveying, drying (or drying), hot pressing, calendering, and edge trimming. It is completed intermittently by workshop workers. Due to size mismatch, transportation loss and other reasons between the various processes, more raw materials are wasted, and the production efficiency is low. In order to smoothly connect the various processes of high-density fiberboard production and realize automatic production, the design of the conveying system for the press water and drying process is carried out. The conventional idea is: the existing single-layer water pres...

[0002] At this stage, the production mode of high-density fiberboard mostly adopts intermittent production, including multiple processes such as wet plate palletizing, water pressing, conveying, drying (or drying), hot pressing, calendering, and edge trimming. It is completed intermittently by workshop workers. Due to size mismatch, transportation loss and other reasons between the various processes, more raw materials are wasted, and the production efficiency is low.

In order to smoothly connect the various processes of high-density fiberboard production and realize automatic production, the design of the conveying system for the press water and drying process is carried out. The conventional idea is: the existing single-layer water press and single-layer dryer pass through the conveyor belt. Directly connected, and there is no device to speed up the heat loss, this design makes the water in the plate lose slowly, increases the subsequent drying energy consumption, and makes the disadvantages of low processing efficiency and low conveying efficiency
