Description
Technical field
The invention belongs to the leather machine technical field, be specifically related to a kind of water squeezing striking-out machine rubber roll felt roll rotary synchronous hydraulic efficiency system.
Background technology
The water squeezing striking-out machine is adapted to before leather industry leather shaping drying, wet leather base be carried out processing treatment.To be stretched to main or stretching, extension, water squeezing are laid equal stress on, make that leather surface stretches, grain is clear, the surperficial coarse groove that produces in neck line, fold and the front processing thereof of removing crust leather etc., squeeze out simultaneously part moisture, the leather fiber is tentatively finalized the design, reduce the percentage reduction of area of crust leather in drying, can improve yield of leather.The feeding of water squeezing striking-out machine and water squeezing work are to be completed by the interaction of rubber roll and felt roll, exerted pressure by felt roll, thereby being clamped in the moisture extrusion in leather between rubber roll and felt roll, and make whole leather obtain effective water squeezing by the relative rotation of rubber roll and felt roll.
The rotation of general water squeezing striking-out machine rubber roll and felt roll is after driving the differential reduction gearbox speed change by oil motor, differential reduction gearbox drives respectively rubber roll and felt roll by two output shafts, due to the effect of differential reduction gearbox, guarantee that rubber roll and felt roll bark pocket place tangential direction speed are identical.Guarantee rubber roll and the felt roll bark pocket place identical mechanism of tangential direction speed by differential reduction gearbox, volume is large, and noise is high, and maintenance difficult is brought great inconvenience to the user.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the purpose of this invention is to provide a kind of water squeezing striking-out machine rubber roll felt roll rotary synchronous hydraulic efficiency system, with realize the rotation of rubber roll and felt roll by separately oil motor drive and can guarantee rubber roll and felt roll bark pocket place tangential direction speed identical, thereby guarantee the stability of water squeezing striking-out machine water squeezing and stretching, extension, to satisfy service requirements.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution used in the present invention is as follows:
A kind of water squeezing striking-out machine rubber roll felt roll rotary synchronous hydraulic efficiency system comprises the rubber roll oil motor that is arranged on the rubber roll axle head and the felt roll oil motor that is installed on the felt roll axle head; Described rubber roll oil motor and felt roll oil motor are connected on the hydraulic efficiency oil main pipe rail; Be parallel with fuel volume adjusting pipeline and valve between the turnover hydraulic oil port of described felt roll oil motor.
Described pipeline comprises that first transfers oil line, second to transfer oil line and pipeline road; Described valve comprises the first check valve, the second check valve, surplus valve, the 3rd check valve and the 4th check valve; Described the first check valve and the 4th check valve are connected on first and transfer on oil line; Described the second check valve and the 3rd check valve are connected on second and transfer on oil line; Described surplus valve is located on pipeline road, described pipeline road into and out of hydraulic fluid port respectively correspondence be located between the first check valve and the 4th check valve, between the second check valve and the 3rd check valve.
Beneficial effect: compared with prior art, water squeezing striking-out machine rubber roll felt roll rotary synchronous hydraulic efficiency system of the present invention, synchronous effect is good, simple in structure, take up room little, adjust easy to maintenancely, have good practicality.Efficient is high, can guarantee the stability of rubber roll and felt roll synchronous working, stretches quality thereby improve water squeezing, can produce good economic benefit and social effect.
Description of drawings
Fig. 1 is water squeezing striking-out machine rubber roll felt roll working state schematic representation;
Fig. 2 is the hydraulic schematic diagram of water squeezing striking-out machine rubber roll felt roll rotary synchronous hydraulic efficiency system.
Embodiment
Below in conjunction with concrete accompanying drawing, the present invention is further described.
As depicted in figs. 1 and 2, water squeezing striking-out machine rubber roll felt roll rotary synchronous hydraulic efficiency system comprises the rubber roll oil motor 1 that is arranged on the rubber roll axle head, the felt roll oil motor 2 that is installed on the felt roll axle head, the first check valve 3, the second check valve 4, surplus valve 5, the 3rd check valve 6 and the 4th check valve 7.rubber roll oil motor 1 is connected on hydraulic efficiency oil main pipe rail 8 with felt roll oil motor 2, be parallel with two fuel volume adjusting pipelines between the inlet and outlet of fuel channel of felt roll oil motor 2, be provided with two check valves on every pipeline, namely being respectively first transfers oil line 9 and second to transfer oil line 10, the first check valve 3 and the 4th check valve 7 are connected on first and transfer on oil line 9, the second check valve 4 and the 3rd check valve 6 are connected on second and transfer on oil line 10, transfer oil line 9 and second to transfer between oil line 10 first and also be provided with pipeline road 11, establish surplus valve 5 on pipeline road 11, advancing of pipeline road 11, oil outlet correspondence respectively is located between the first check valve 3 and the 4th check valve 7, between the second check valve 4 and the 3rd check valve 6.
During forward work, for making felt roll 13 identical with the bark pocket tangential direction speed V of place between rubber roll 12, the hydraulic fluid flow rate of rubber roll oil motor 1 is greater than felt roll oil motor 2, therefore, during through rubber roll oil motor 1, part hydraulic efficiency oil directly enters felt roll oil motor 2 from the hydraulic efficiency oil of main pipe rail 8 output, and remaining hydraulic efficiency oil flows into main pipe rails 8 outlets through the second check valve 4, surplus valve 5, the 4th check valve 7, at this moment, the first check valve 3 and the 3rd check valve 6 are closed.In like manner, during counter-rotating work, felt roll oil motor 2 hydraulic fluid flow rates are less than rubber roll oil motor 1, first directly enter rubber roll oil motor 1 through felt roll oil motor 2 from the hydraulic efficiency oil part of main pipe rail 8 outputs, remaining hydraulic efficiency oil flows into rubber roll oil motor 1 again through the 3rd check valve 6, surplus valve 5, the first check valve 3, at this moment, the second check valve 4, the 4th check valve 7 and close; Thereby realize the adjustment of the bark pocket tangential direction speed V of place between felt roll 13 and rubber roll 12, make the water squeezing stretching, extension quality of leather 14 be improved.
This water squeezing striking-out machine rubber roll felt roll rotary synchronous hydraulic efficiency system, synchronous effect is good, simple in structure, take up room little, adjust easy to maintenance.Efficient is high, can guarantee the stability of rubber roll and felt roll synchronous working, stretches quality thereby improve water squeezing, can produce good economic benefit and social effect.
