Technical scheme: in order to realize foregoing invention object, the technical solution used in the present invention is as follows:
A kind of water squeezing striking-out machine rubber roll felt roll rotates synchronization hydraulic system, comprises the rubber roll oil motor being arranged on rubber roll axle head and the felt roll oil motor being installed on felt roll axle head; Described rubber roll oil motor and felt roll oil motor are connected on hydraulic efficiency oil main pipe rail; Fuel volume adjusting pipeline and valve is parallel with between the turnover hydraulic oil port of described felt roll oil motor.
Described pipeline comprises the first tune oil line, second and adjusts 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; The first described check valve and the 4th check valve are connected on the first tune oil line; The second described check valve and the 3rd check valve are connected on the second tune 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 of the present invention rotates synchronization hydraulic system, and synchronous effect is good, and structure is simple, it is little to take up room, it is easy to maintenance to adjust, and has good practicality.Efficiency is high, can ensure the stability of rubber roll and felt roll synchronous working, thus improves water squeezing stretching, extension quality, can produce good economic benefit and social effect.
Accompanying drawing explanation
Fig. 1 is water squeezing striking-out machine rubber roll felt roll working state schematic representation;
Fig. 2 is the hydraulic schematic diagram that water squeezing striking-out machine rubber roll felt roll rotates synchronization hydraulic 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 rotates synchronization hydraulic system, comprises the rubber roll oil motor 1 being arranged on rubber roll axle head, felt roll oil motor 2, first check valve 3, second check valve 4, surplus valve 5, the 3rd check valve 6 and the 4th check valve 7 that are installed on felt roll axle head.Rubber roll oil motor 1 and felt roll oil motor 2 are connected on hydraulic efficiency oil main pipe rail 8, two fuel volume adjusting pipelines are parallel with between the inlet and outlet of fuel channel of felt roll oil motor 2, every bar pipeline is provided with two check valves, namely be respectively the first tune oil line 9 and second and adjust oil line 10, first check valve 3 and the 4th check valve 7 are connected on the first tune oil line 9, second check valve 4 and the 3rd check valve 6 are connected on the second tune oil line 10, adjust between oil line 9 and the second tune oil line 10 first and be also provided with pipeline road 11, pipeline road 11 is established surplus valve 5, entering of pipeline road 11, oil outlet respectively correspondence is located between the first check valve 3 and the 4th check valve 7, between second check valve 4 and the 3rd check valve 6.
During rotating forward work, for making the bark pocket place tangential direction speed V between felt roll 13 with rubber roll 12 identical, the hydraulic fluid flow rate of rubber roll oil motor 1 is greater than felt roll oil motor 2, therefore, the hydraulic efficiency oil exported from main pipe rail 8 is when the rubber roll oil motor 1, and section hydraulic oil directly enters felt roll oil motor 2, and remaining hydraulic efficiency oil flows into main pipe rail 8 export through the second check valve 4, surplus valve 5, the 4th check valve 7, now, the first check valve 3 and the 3rd check valve 6 are closed.In like manner, during reversion work, felt roll oil motor 2 hydraulic fluid flow rate is less than rubber roll oil motor 1, the hydraulic efficiency oil part exported from main pipe rail 8 first directly enters rubber roll oil motor 1 through felt roll oil motor 2, remaining hydraulic efficiency oil flows into rubber roll oil motor 1 again through the 3rd check valve 6, surplus valve 5, first check valve 3, now, the second check valve 4, the 4th check valve 7 and closedown; Thus realize the adjustment of the bark pocket place tangential direction speed V between felt roll 13 and rubber roll 12, make the water squeezing of leather 14 stretch quality and be improved.
This water squeezing striking-out machine rubber roll felt roll rotates synchronization hydraulic system, and synchronous effect is good, and structure is simple, it is little to take up room, it is easy to maintenance to adjust.Efficiency is high, can ensure the stability of rubber roll and felt roll synchronous working, thus improves water squeezing stretching, extension quality, can produce good economic benefit and social effect.
