[0002] In the existing high-speed press, there is oil stored in the end cover at the lower end of the slider guide column. The oil returns by gravity, which is slow, and it also causes the oil in the oil storage box not to be completely returned. The leaked oil will contaminate the material, making the finally blanked parts difficult to clean, and it takes time to clean, which is time-consuming and laborious and does not meet the cleanliness standards of the food industry.

[0003] Therefore, there is an urgent need for a simple and practical device to solve this problem, which can quickly pump out the oil stored in the oil collecting end cover, and this device does not require much installation space and does not increase much cost. Summary of the Utility Model

The two-position two-way solenoid valve is connected to the vacuum generator. The vacuum generator is connected to the vacuum pump device. One side of the vacuum generator is also connected to the first oil pipe assembly. The upper part of the vacuum pump device is provided with an exhaust port, and the lower part of the vacuum pump device is connected to the second oil pipe assembly.

[0007] Preferably, the filter pressure reducing valve is connected to the two-position two-way solenoid valve through a second steel pipe, and a twelfth joint is arranged on the filter pressure reducing valve for introducing compressed air.

[0011] The beneficial effects of the present utility model are as follows: By arranging a filter pressure reducing valve, a two-position two-way solenoid valve, and a vacuum generator, compressed air passes through the nozzle of the vacuum generator, generating a high-speed discharge.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] A high-speed press vacuum oil suction device, the device includes a vacuum pump device 3, a vacuum generator 16, a two-position two-way solenoid valve 20, a filter pressure reducing valve 22, an oil pipe assembly one 11, an oil pipe assembly two 13 and several joints;

[0015] One end of the filter pressure reducing valve 22 is the compressed air inlet, and the other end is connected to the two-position two-way solenoid valve 20. The two-position two-way solenoid valve 20 is connected to the vacuum generator 16. The vacuum generator 16 is connected to the vacuum pump device 3. One side of the vacuum generator 16 is also connected to the oil pipe assembly one 11. The upper part of the vacuum pump device 3 is provided with an exhaust port, and the lower part of the vacuum pump device 3 is connected to the oil pipe assembly two 13.

[0016] The filter pressure reducing valve 22 is connected to the two-position two-way solenoid valve 20 through the second steel pipe 24, and the filter pressure reducing valve 22 is provided with the twelfth joint 23 for introducing compressed air.

[0017] The two-position two-way solenoid valve 20 is connected to the PU hose 18 through the eleventh joint 19. The upper end of the vacuum generator 16 is connected to the PU hose 18 through the tenth joint 17. The lower end of the vacuum generator 16 is connected to one end of the first steel pipe 9 through the ninth joint 15 and the eighth joint 14. The lower end of the vacuum pump device 3 is connected to the other end of the first steel pipe 9 through the third joint 5 and the fourth joint 6. A filter 4 is arranged inside the vacuum pump device 3.

[0018] The first steel pipe 9 is a U-shaped steel pipe.

[0019] The described tubing assembly 11 is connected to the oil collecting end cover 12.

[0020] The working process of the present utility model is as follows: As Figure 1 shown, A is the compressed air inlet; B is the oil outlet; C is the oil inlet; D is the exhaust port.

[0021] Compressed air enters from A, passes through the filter pressure reducing valve 22, which can filter out water and impurities in the air and can reduce the pressure of the compressed air (to stabilize the pressure of the compressed air). After decompression, the clean compressed air enters the inlet of the two-position two-way solenoid valve 20. After it is energized, the compressed air enters the intake nozzle of the vacuum generator 16 through the PU hose, generating high-speed gas, which drives the oil at side C into the vacuum generator 16. Then, it flows out of the vacuum generator 16 together with the air flow, enters the vacuum pump device 3 through the first steel pipe, and passes through the filter 4 inside it to reduce the gas-liquid flow rate and separate the air and the oil. Since the air has a small density and is light in weight, it is discharged upward through D; while the oil has a large density and is heavy in weight, it sinks to the lower part of the vacuum pump device 3 and is discharged back to the oil collecting tank through B.
