Hydraulic system of single face machine

Abstract

The invention relates to a hydraulic system of a single face machine. The system comprises a motor, a high-pressure pump and a hydraulic integrated block, wherein the motor is connected with the high-pressure pump; the high-pressure pump is connected with an oil tank through a pipeline to absorb oil, is connected with the hydraulic integrated block by a one-way valve through a pipeline and entersthe P port of the hydraulic integrated block; the P port of the hydraulic integrated block is communicated with the P port of an electromagnetic reversing valve and the P port of an overflow valve respectively; the T port of the electromagnetic reversing valve is communicated with the T port of the hydraulic integrated block; the T port of the overflow valve is communicated with the T port of thehydraulic integrated block; the T port of the hydraulic integrated block is communicated with the oil tank through a pipeline; the A port of the electromagnetic reversing valve is communicated with two rod cavities of an oil cylinder; and the B port of the electromagnetic reversing valve is communicated with a one-way pressure reducing valve and is respectively communicated with rodless cavities of the oil cylinder. The one-way pressure reducing valve provides different supply pressure for different oil cylinders, so that a plurality of motors are saved; a large energy accumulator is adopted,so that the system is more energy-saving and consumption is reduced; and the one-way pressure reducing valve always provides constant pressure for the oil cylinder.

Description

technical field [0001] The invention relates to a single-facer hydraulic system used for extruding and forming paper and coating and pasting it into cardboard in the production process of cartons. Background technique [0002] The hydraulic system of the single-sided machine is used in the important process of extruding the paper and pasting it into cardboard during the carton production process. The novelty of the system lies in the principle design, which can squeeze the paper without breaking. [0003] At present, in the carton production process, the forming process of the cardboard is pneumatic, and the gas compression ratio is large, the stability is not good, and the volume is large. The hydraulic system that appears on the market is complex in design and high in cost. The hydraulic system of this new single-sided machine can be realized by only one motor with a power of 3KW. It is simple to manufacture and has a beautiful appearance. Contents of the invention ...
