Description

Technical Field

[0001] This utility model relates to the technical field of lubrication devices, specifically to a lubrication device for a bearing of an air-jet spinning cup. Background Technology

[0002] In air-jet spinning equipment, the lubrication of the rotor bearings is crucial, as its effectiveness directly impacts the equipment's operating efficiency and lifespan. Good lubrication effectively reduces bearing wear, lowers equipment failure rates, and improves production efficiency.

[0003] Chinese patent document CN201111582Y discloses a device for lubricating bearings, particularly suitable for lubricating rotor bearings in air-jet spinning. The device includes a handheld frame, a ratchet, a pawl, a wrench, a limiting shaft, and a syringe. The wrench is connected to the handheld frame via a rotating shaft, on which a return spring is mounted. One end of the return spring rests against the wrench, and the other end is hinged to the handheld frame, allowing the wrench to return to its original position at any time. The pawl is pivotally connected to the end of the wrench, and a reset plate is fixed to the end of the wrench, pressing against the pawl. This existing lubrication device is inconvenient for freely adjusting the amount of lubricant according to different bearing specifications. In air-jet spinning equipment, different sizes of rotor bearings have different lubrication requirements. Excessive lubrication may lead to lubrication leakage, wasting lubricant and potentially contaminating the equipment and working environment; insufficient lubrication will fail to meet the bearing's lubrication needs, affecting the normal operation of the equipment.

[0004] Therefore, a lubrication device for air-jet spinning cup bearings is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a lubrication device for the bearing of an air-jet spinning cup in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A lubrication device for an air-jet spinning cup bearing includes a storage tube containing lubricating oil. A mounting shell is fixedly fitted onto the surface of the storage tube, and a metering tube is fixedly connected to the bottom of the mounting shell. A feeding assembly for feeding the lubricating oil from the storage tube into the metering tube is provided on the surface of the mounting shell. An oil volume control mechanism for adjusting the amount of lubricating oil in the metering tube is provided on the surface of the storage tube. A handle is fixedly connected to the right side of the bottom surface of the storage tube. A filling assembly for discharging the lubricating oil from the metering tube is installed on the back of the storage tube. A control module is fixedly installed on the front of the storage tube.

[0007] Furthermore, the feeding assembly includes a first electric push rod, which is fixedly installed on the top surface of the storage tube. A first connecting rod is fixedly connected to the telescopic end of the first electric push rod. A round shaft is fixedly connected to the end of the first connecting rod.

[0008] Furthermore, the oil quantity control mechanism includes a second piston block, which is slidably connected to the inner wall of the metering tube. A support column is fixedly connected to the right side of the second piston block, and a pressure block is fixedly connected to the end of the support column. A baffle is fixedly connected to the surface of the pressure block. A bent rod is provided on the right side of the pressure block, and a pressure sensor is fixedly connected to the left side of the bent rod. The oil quantity control mechanism also includes an adjustment component for controlling the movement of the bent rod.

[0009] Furthermore, the adjustment assembly includes a housing, which is fixedly connected to the surface of the storage tube.

[0012] The beneficial effects of this utility model are as follows: The lubricating oil for the air-jet spinning cup bearing is stored inside a storage tube. When refilling is needed, the feeding component introduces the lubricating oil into the metering tube. The oil quantity is adjusted by an oil quantity control mechanism based on the different oil requirements of each bearing. Then, the filling component discharges all the lubricating oil from the metering tube and fills the bearing, thus completing the refilling process.

[0019] like Figures 1 to 4 As shown, an oiling device for an air-jet spinning cup bearing includes a storage tube 1, which stores lubricating oil. A mounting shell 2 is fixedly sleeved on the surface of the storage tube 1, and a metering tube 4 is fixedly connected to the bottom of the mounting shell 2. A feeding assembly 3 for feeding the lubricating oil from the storage tube 1 into the metering tube 4 is provided on the surface of the mounting shell 2. The feeding assembly 3 includes a first electric push rod 301, which is fixedly installed on the top surface of the storage tube 1. A first connecting rod 302 is fixedly connected to the telescopic end of the first electric push rod 301. A round shaft 303 is fixedly connected to the end of the first connecting rod 302. A first piston block 304 is fixedly connected to the end of the round shaft 303, and the surface of the first piston block 304 is slidably connected to the inner wall of the storage tube 1. A connecting pipe 305 is fixedly connected between the storage tube 1 and the metering tube 4, and a one-way valve 306 is provided at the end of the connecting pipe 305. It should be noted that the operation of the first electric push rod 301 can drive the first connecting rod 302 to move, thereby driving the round shaft 303 and the first piston block 304 to move, thereby exporting the lubricating oil inside the storage tube 1. The lubricating oil will be sent into the metering tube 4 along with the connecting tube 305.

[0020] The surface of the storage tube 1 is provided with an oil quantity control mechanism 5 for adjusting the amount of lubricating oil inside the metering tube 4. The oil quantity control mechanism 5 includes a second piston block 501, which is slidably connected to the inner wall of the metering tube 4. A support column 502 is fixedly connected to the right side of the second piston block 501. A pressure block 503 is fixedly connected to the end of the support column 502. A baffle 504 is fixedly connected to the surface of the pressure block 503. A bent rod 505 is provided on the right side of the pressure block 503. A pressure sensor 506 is fixedly connected to the left side of the bent rod 505. The oil quantity control mechanism 5 also includes an adjustment component for controlling the movement of the bent rod 505. More specifically, when the connecting pipe 305 injects lubricating oil into the metering pipe 4, it will push the second piston block 501 to move, thereby driving the support column 502, pressure block 503 and baffle 504 to move, so that the baffle 504 eventually contacts the surface of the pressure sensor 506. When the pressure sensor 506 detects the preset pressure value, the feeding assembly 3 will stop operating, and the user can obtain the specified amount of lubricating oil.

[0021] The adjustment assembly includes a housing 507, which is fixedly connected to the surface of the storage tube 1. A threaded rod 508 is rotatably connected to the inner wall of the housing 507. A knob 509 is fixedly connected to the right end of the threaded rod 508. The surface of the threaded rod 508 is threadedly connected to a bent rod 505. A sliding groove 510 is provided through the front of the housing 507, and the inner wall of the sliding groove 510 is slidably connected to the surface of the bent rod 505. A scale line 511 is provided on the front of the housing 507, and a pointer 512 is fixedly connected to the top surface of the bent rod 505. It should be noted that by rotating the knob 509, the threaded rod 508 is rotated. Under the action of the thread, the bent rod 505 will slide along the inner wall of the sliding groove 510, thereby adjusting the position of the bent rod 505 and the pressure sensor 506. This changes the maximum position of the pressure block 503 moving to the right, thus adjusting the amount of lubricating oil that the metering tube 4 can hold. The position of the bent rod 505 can be accurately controlled by setting the scale line 511 and the pointer 512.

[0022] A handle 6 is fixedly connected to the right side of the bottom surface of the storage tube 1. A filling assembly 7 for outputting lubricating oil from the metering tube 4 is installed on the back of the storage tube 1. The filling assembly 7 includes a second electric push rod 701, which is fixedly installed on the back of the storage tube 1. A second connecting rod 702 is fixedly connected to the telescopic end of the second electric push rod 701. A mounting plate 703 is fixedly connected to the end of the second connecting rod 702. An oil injection pipe 704 is fixedly inserted into the left side of the metering tube 4. A control valve 705 is provided at the right end of the oil injection pipe 704. More specifically, by operating the second electric push rod 701, the second connecting rod 702 is driven to move, thereby driving the mounting plate 703 to move. By using the mounting plate 703 to contact the surface of the pressure block 503, the pressure block 503, the support column 502, and the second piston block 501 can be pushed to move. The lubricating oil inside the metering tube 4 can be output from the oil injection pipe 704, thus lubricating the bearing surface of the air-jet spinning cup.

[0023] A control module 8 is fixedly mounted on the front of the storage tube 1. A sponge sleeve is fixedly fitted onto the surface of the storage tube 1. It should be noted that by setting the sponge sleeve, the friction with the hand is increased, making the grip more stable for the user.

[0024] In summary: the lubricating oil for the air-jet spinning cup bearing is stored inside the storage tube 1. When refilling is needed, the feeding assembly 3 operates to introduce the lubricating oil into the metering tube 4. Depending on the different bearings requiring different amounts of oil, the oil quantity control mechanism 5 adjusts the amount of oil stored in the metering tube 4. Subsequently, the filling assembly 7 discharges all the lubricating oil from the metering tube 4 and introduces it into the bearing, thus completing the refilling process. The control module 8 can control the feeding assembly 3, the oil quantity control mechanism 5, and the filling assembly 7. The control module 8 can use a conventional control device, and the specific circuit principle will not be elaborated here.
