Hydraulic machine for single-piece fiber cement plate pressing

Abstract

The invention relates to a hydraulic machine for single-piece fiber cement plate pressing. The hydraulic machine is characterized by comprising a hydraulic machine body and a multi-station conveying device, the hydraulic machine body is arranged in the middle of the multi-station conveying device, the multi-station conveying device comprises a conveyer belt, a driving roller, two tensioning rollers and a high-pressure water cleaning roller, the driving roller, one tensioning roller, the high-pressure water cleaning roller and the other tensioning roller are arranged in sequence to form the cyclic multi-station conveying device, a plate blank conveying machine and a dewatered plate blank conveying machine are arranged on the left side and right side of the hydraulic machine body, and plate blank suckers are arranged above the plate blank conveying machine and the dewatered plate blank conveying machine respectively. The hydraulic machine has the advantages that a plate blank or a pressed dewatered plate blank is directly conveyed to the pressing station or stacking station through the multi-station conveying device extending to the two ends of the hydraulic machine body, and vertical drainage can be achieved quickly during pressing due to the fact that the plate blank is conveyed through the fibrage conveyer belt.

Description

technical field [0001] The invention belongs to special equipment for building materials, in particular to a hydraulic press for pressing a single fiber cement board. Background technique [0002] Fiber cement boards are widely used in construction. At present, the domestic production is made by the stacking pressing process. That is, there is a template under a piece of product, which is stacked to a certain height and entered into the hydraulic press for slow pressing to drain the water, and then enter the next stripping process. The disadvantage of the above process is that it must drain water around the board stack, so the dehydration time is long, and the thickness of the board is uneven; therefore, the single-piece pressing process is also used abroad, which puts the slab on many templates with small holes for pressing. Drain vertically, then take off the formwork, and enter the stacking oxygen evaporation process, but the required motor power is high, and the proces...

The disadvantage of the above process is that it must drain water around the board stack, so the dehydration time is long, and the thickness of the board is uneven; therefore, the single-piece pressing process is also used abroad, which puts the slab on many templates with small holes for pressing. Drain vertically, then take off the formwork, and enter the stacking oxygen evaporation process, but the required motor power is high, and the process is relatively complicated, so it has not been widely used
