A three-way element is connected between the quantitative valve and the cylinder. A spring is arranged between the output shaft of the cylinder and the oil injection rod.

[0003] The above-mentioned refueling device can refuel the bearings at both ends of the double-headed rubber roller at the same time, so that refueling can be done quickly. However, due to the high viscosity of the grease, especially in winter when the temperature is low, the viscosity of the grease increases significantly, and the grease is transported slowly in the oil pipe, resulting in slow refueling. Therefore, it is necessary to improve it to solve the above problem. Summary of the invention

DETAILED DESCRIPTION

[0016] The oiling device of the double-head rubber roller of the spinning frame is composed of a base 1, a lifting pump 2, a distributor 3 arranged on the base 1 and a symmetrically arranged oiling mechanism. The distributor 3 is connected to the oiling mechanism and the lifting pump 2 through an oil pipe 4 respectively; a heating resistance wire 5 is wound around the oil pipe 4 between the distributor 3 and the oiling mechanism and between the distributor 3 and the lifting pump 2 respectively, so that the oil pipe 4 is heated by the heating resistance wire 5, and then the grease in the oil pipe 4 is heated, and the viscosity of the grease in the whole device is reduced by heating, thereby reducing the flow resistance of the grease in the whole device, so that The grease can flow quickly, thereby shortening the grease filling time, effectively speeding up the grease filling, and improving the grease filling efficiency; at the same time, since the heating resistance wire 5 is wound on the oil pipe 4, the heating resistance wire 5 can continuously heat the grease at a relatively low power, ensuring that the grease can be heated to the required temperature while ensuring safety, thereby reducing the viscosity of the grease and ensuring that the grease is not easy to cool during the filling process; in addition, by heating to reduce the flow resistance of the grease in the oil pipe, the pressure at the outlet of the volume pump 2 can be reduced, so that the volume pump 2 can pump the grease faster.

[0017] The oil injection mechanism is composed of a slide 6, a metering valve 7, a push cylinder 8 and a connector. A support plate 9 is movably mounted on the slide 6, a metering valve 7 is fixedly mounted on the upper part of the support plate 9, a push cylinder 8 is arranged on the outer side of the metering valve 7, and the piston rod end of the push cylinder 8 is fixedly connected to the support plate 9; a connector is arranged on the oil outlet inside the metering valve 7; the metering valve 7 is connected to the distributor 3 through the oil pipe 4; the slide 6 and the push cylinder 8 are respectively connected to the base 1. The function of the push cylinder 8 is to push the support plate 9 to move through the push cylinder 8, and then push the metering valve 7 on the support plate 9 to move, thereby driving the connector to move during the movement of the metering valve 7, so that the connector is squeezed on the end face of the double-headed rubber roller and connected to the double-headed rubber roller, so that the grease can be injected into the bearing at the end of the double-headed rubber roller through the metering valve 7 and the connector in sequence. Since the connector is directly connected to the metering valve 7, the oil pipe is removed between the metering valve 7 and the connector, which can effectively shorten the flow distance of the grease, thereby further improving the grease filling efficiency and achieving rapid grease filling.

[0018] The connector is composed of a connecting sleeve 10, an assembly end cap 11 and an oil nozzle 12. The assembly end cap 11 is threadedly installed on one end of the connecting sleeve 10. The oil nozzle 12 is movably inserted on the assembly end cap 11, so that the end of the oil nozzle 12 is inserted into the oil filling port of the double-headed rubber roller bearing. When the grease flows outward through the connecting sleeve 10 and the oil nozzle 12 in sequence, the double-headed rubber roller bearing is filled with grease through the end of the oil nozzle 12 inserted into the double-headed rubber roller bearing. The other end of the connecting sleeve 10 is threadedly connected to the oil outlet of the metering valve 7.

[0019] A buffer spring 13 is arranged in the connecting sleeve 10 between the oil nozzle 12 and the oil outlet of the metering valve 7 to buffer the oil nozzle 12 during the process of inserting the oil nozzle 12 into the metering valve 7. The buffer spring 13 prevents the oil nozzle 12 from rigidly colliding with the double-headed rubber roller, reduces the collision force between the oil nozzle 12 and the double-headed rubber roller, and effectively protects the oil nozzle 12 and the double-headed rubber roller.

[0020] A positioning plate 14 is threadedly installed on the end of the oil nozzle 12, so that the positioning plate 14 rests on the end face of the double-headed rubber roller to limit the oil nozzle 12, avoid the oil nozzle 12 from being excessively inserted into the double-headed rubber roller, and protect the oil nozzle 12 and the oil filling port of the double-headed rubber roller; at the same time, the end face of the double-headed rubber roller is sealed by the positioning plate 14, thereby sealing the oil filling port of the double-headed rubber roller all around to prevent leakage during the grease filling process and avoid wasting grease.

[0021] The slide 6 between the connectors is symmetrically provided with support seats 15 to support the double-headed rubber roller through the support seats 15 to position the double-headed rubber roller, so as to facilitate the connection between the connector and the double-headed rubber roller.

[0022] When the oiling device of the double-headed rubber roller of the spinning machine fills the double-headed rubber roller with oil, the inlet of the lifting pump 2 is inserted into the grease barrel. After the lifting pump 2 is inserted into place, the heating resistance wire 5 wound on the oil pipe 4 is energized to preheat the oil pipe 4. After the temperature of the oil pipe 4 rises to the set value, the double-headed rubber roller is placed on the support seat 15 on the slide 6. After the double-headed rubber roller is placed in place, the push cylinder 8 of the oiling mechanism on both sides of the double-headed rubber roller is started, and the push cylinder 8 pushes the connector against the two ends of the double-headed rubber roller through the support plate 9 and the metering valve 7 in turn, so that the oil nozzle 12 of the connector is inserted into the oil filling port at both ends of the double-headed rubber roller. After the oil nozzle 12 is inserted into place, the lifting pump 2 is started, and the lifting pump 2 injects the grease into the bearings at both ends of the double-headed rubber roller through the distributor 3, the metering valve 7, and the connector in turn. During the process of filling the grease, the heating resistance wire is kept heated to keep the grease heated.

[0023] The oiling device of the double-head rubber roller of the spinning machine can heat the grease in the oil pipe through the heating resistance wire 5, reduce the viscosity of the grease when it is transported in the whole device by heating, reduce the flow resistance of the grease in the oil pipe, make the grease flow quickly, and thus quickly refuel, effectively improve the refueling efficiency; by setting the connector at the oil outlet of the metering valve 7, the metering valve 7 can be directly connected to the connector, and the oil pipe between the metering valve 7 and the connector can be removed, effectively shortening the flow distance of the grease, further improving the grease transportation efficiency, and thus further improving the refueling efficiency. The problem of slow refueling and low refueling efficiency of the existing refueling device is solved.
