Hydraulic control method for hide meat splitter and special device thereof

Abstract

The invention discloses a hydraulic control method for a hide meat splitter and a special device thereof. The method comprises the following steps of: connecting downstream meat-splitting pressure oil cylinders in parallel into groups by using an upstream oil supply control system, wherein a main pipeline of each group is provided with an overflow valve, and connecting the main pipelines of the groups in parallel to the upstream oil supply control system; and controlling the overflow valves under different pressures so as to fulfill the aim of producing different pressures among parallel meat-splitting pressure oil cylinder groups. In the hydraulic control method for the hide meat splitter and the special device thereof, the meat-splitting pressure oil cylinders are treated in groups and different pressures are produced among different groups, so that different leather and different positions of the leather can be treated under different pressures, the meat splitting quality of the leather is improved greatly, the production efficiency of a machine is improved rapidly and production requirements can be met.

Description

technical field [0001] The invention relates to a leather machine, in particular to a hydraulic control method of a leather flesher and a special device thereof. Background technique [0002] At present, the commonly used fleshing machines are all traditional mechanical transmission forms, using pedal clutch, crank drive, rocker drives the feeding rod to drag the leather to slide along the guide rail surface, and the feeding roller and small feeding roller move at the same time. The leather is sent to the high-speed rotating knife roller for de-fleshing process. The advantage of adopting this transmission mode is low cost, simple operation and convenient maintenance; the disadvantage is that the service life is low, it is difficult to ensure a clean meat removal, and the work efficiency is low. [0003] There are also some hydraulic meat removers that are not commonly used in the market. During the meat remover process, when the meat is removed until it has connective tissu...

Problems solved by technology

The advantages of using this transmission mode are low cost, simple operation and convenient maintenance; the disadvantage is that the service life is low, it is difficult to ensure a clean meat removal, and the work efficiency is low

[0003] There are also some hydraulic meat removers that are not commonly used in the market. During the meat remover process, when the meat is removed until it has connective tissue, due to the high hardness and toughness of the connective tissue, the local knife roller will not be used for leather and skin. The rubber roller forms a large pressure, while the pressure elsewhere is much smaller. Under the action of this pressure difference, it is easy to tear the leather, and in severe cases, the rubber roller will be damaged. Therefore, this machine cannot meet the requirements for use.
