Description

Technical Field

[0001] This utility model relates to the field of spinning processing technology, and in particular to an oil metering device for spinning processing. Background Technology

[0002] In the spinning process, the oil metering device is a key piece of equipment to ensure the uniformity of oil application to the filament bundle and the stability of subsequent processing. Its core component is the metering gear inside the oil pump. Traditional oil pumps typically use metering gears with uniform tooth size. Through gear meshing, a chamber with a fixed volume is formed, delivering the oil at a stable rate to ensure a consistent oil thickness on the filament bundle. This, in turn, maintains the stability of the filament friction coefficient and drawing tension, meeting the uniformity requirements of conventional FDY (fully drawn yarn) production. Meanwhile, in the production of polyester slub yarn, the stability of oil metering also indirectly affects the slub formation effect. Especially in the production of fine denier polyester FDY short slub yarn, subtle differences in the oil coating thickness can be one of the key factors contributing to the formation of the slub structure.

[0003] However, in practical applications, while the uniform metering gear design of traditional oil pumps can meet the needs of conventional spinning, it cannot adapt to the production requirements of fine denier polyester FDY multi-patterned short slub yarns. Existing metering gears cannot provide differentiated oiling speed frequency variations, nor can they create fluctuations in the friction coefficient between the yarn bundle and the yarn path through differences in oil thickness. Consequently, they cannot provide uneven tension conditions for the yarn bundle before drafting, which is detrimental to the precise forming of short slub structures. Therefore, a new technical solution is urgently needed to solve at least one of the above technical problems. Summary of the Invention

[0004] In view of the above shortcomings, the purpose of this utility model is to provide an oil metering device for spinning processing. By replacing the uneven gears with different geometric shapes, the oiling frequency variation pattern can be flexibly adjusted to adapt to the production needs of multi-patterned bamboo joint style.

[0005] To achieve the above-mentioned technical objectives and meet the above-mentioned technical requirements, the technical solution adopted by this utility model is as follows: A spinning oil metering device includes a base plate. An oil pump body and an oil tank, spaced apart on the left and right sides, are fixedly connected to the top of the base plate. A first motor is fixedly connected to the top of the oil pump body. A gear metering groove is provided inside the oil pump body, and two meshing metering gears are rotatably connected within the gear metering groove. The output end of the first motor is fixedly connected to the central shaft of one of the metering gears. The teeth on the metering gear are unevenly sized. An oil outlet communicating with the gear metering groove is provided on the left side of the oil pump body, and an oil inlet communicating with the gear metering groove is provided on the right side of the oil pump body. An oil delivery pipe is connected to the bottom of the oil tank, and the other end of the oil delivery pipe is connected to the oil inlet of the metering groove. A stirring mechanism is provided in the lower half of the oil tank. The top of the oil tank is open and detachably connected to a tank cover by screws. An oil replenishment port is provided at the center of the top of the tank cover. A cylindrical oil filter frame adapted to the oil replenishment port is detachably provided at the bottom of the tank cover, and an anti-clogging component is provided on the cylindrical oil filter frame.

[0006] As a preferred technical solution, a liquid level sensor is fixedly connected to the middle of the inner wall of the oil tank, a heating rod is provided on the lower half of the inner wall of the oil tank, a liquid level observation port is provided on the front side of the oil tank, a liquid level line is provided in the liquid level observation port, a cap is threadedly connected to the top of the oil replenishment port, and a solenoid valve is provided on the oil delivery pipe.

[0007] As a preferred technical solution, the bottom of the cover is fixedly connected to a fixing ring that matches the top of the cylindrical oil filter frame. The top of the cylindrical oil filter frame is inserted into the fixing ring. The fixing ring has two symmetrically distributed mounting cavities inside. A locking rod is slidably disposed in the mounting cavity. The outer ring of the top of the cylindrical oil filter frame has two locking grooves that match the two locking rods respectively. A retaining ring located in the mounting cavity is fixedly connected to the locking rod. A spring located in the mounting cavity is also sleeved on the locking rod. The spring is located on the side of the retaining ring away from the locking groove. A pull block is fixedly connected to the end of the locking rod away from the locking groove.

[0008] As a preferred technical solution, the top outer ring of the cylindrical oil filter frame is also fixedly connected to a guide block, and the bottom of the fixing ring is provided with a guide groove that matches the guide block.

[0009] As a preferred technical solution, the agitation mechanism includes a second motor fixedly connected to the outside of the oil tank, and a rotating rod located inside the oil tank is fixedly connected to the output end of the second motor. Several agitation blades are evenly distributed on the rotating rod.

[0010] As a preferred technical solution, the anti-clogging component includes a third motor fixedly connected to the center of the bottom of the cylindrical oil filter frame. The output end of the third motor is fixedly connected to a connecting plate located inside the cylindrical oil filter frame. Two symmetrically distributed L-shaped scrapers are fixedly connected to the outer ring of the connecting plate. The horizontal plate of the L-shaped scraper is in contact with the inner bottom wall of the cylindrical oil filter frame, and the vertical plate of the L-shaped scraper is in contact with the inner side wall of the cylindrical oil filter frame. A protective shell located outside the third motor is also fixedly connected to the bottom of the cylindrical oil filter frame.

[0011] Compared with traditional technical solutions, the beneficial effects of this utility model are: 1) The oil metering device of this utility model can realize dynamic frequency changes in oiling speed by differentiating the volume of the gear meshing chamber, so that the thickness of the oil coating on the surface of the yarn bundle forms a regular difference. This difference can further change the friction coefficient between the yarn bundle and the yarn path, thereby causing micro-fluctuations in the yarn bundle running tension, providing uneven tension conditions for the subsequent drawing process. Combined with the uneven thickness structure of the nascent yarn formed by turbulent cooling and the disordered drawing points designed by the drawing roller pit, the precise forming of fine denier polyester FDY short slub yarn is finally achieved. Moreover, by replacing the uneven gears with different geometric shapes, the oiling frequency variation can be flexibly adjusted to meet the production needs of multi-patterned slub style without modifying the overall structure of the oil pump, reducing equipment adjustment costs and operation complexity. 2) The oil metering device of this utility model forms a coordinated temperature control and uniformity mechanism by setting an agitation mechanism and a heating rod in the lower half of the oil tank. This effectively prevents the oil from cooling and solidifying. The heating rod can continuously heat the oil in the tank, maintaining the oil in a suitable flow temperature range and preventing the viscosity of the oil from increasing or solidifying in low-temperature environments. At the same time, the agitation mechanism drives the rotating rod and agitator blades to rotate through a second motor, which can quickly and evenly stir the heated oil, avoiding local overheating that could lead to oil deterioration, and also preventing local low temperatures that could cause the oil to solidify. This ensures that the oil always maintains a stable flow state, ensuring smooth oil delivery in the oil pipeline. It avoids the problems of oil pipeline blockage and metering gear jamming caused by oil solidification, and maintains the accuracy of oil metering. This provides a reliable guarantee for the stable supply and dynamic metering of oil in the production of fine denier polyester FDY short slub yarn. Attached Figure Description

[0018] The system integrates the storage, filtration, and metering of oil. The combination of the cylindrical oil filter frame 13 and the anti-clogging component 14 ensures the cleanliness of the oil and the smoothness of its delivery. The stirring mechanism 10 improves the uniformity of the oil, and the removable cover 11 facilitates subsequent maintenance and cleaning. Example

[0019] Furthermore, a liquid level sensor 15 is fixedly connected to the middle of the inner wall of the oil tank 3, a heating rod 16 is provided on the lower half of the inner wall of the oil tank 3, a liquid level observation port 17 is provided on the front side of the oil tank 3, a liquid level line is provided in the liquid level observation port 17, a cap 18 is threadedly connected to the top of the oil replenishment port 12, and a solenoid valve 19 is provided on the oil delivery pipe 9.

Example

[0022] Furthermore, a fixing ring 20 adapted to the top of the cylindrical oil filter frame 13 is fixedly connected to the bottom of the cover 11. The top of the cylindrical oil filter frame 13 is inserted into the fixing ring 20. Two symmetrically distributed mounting cavities 21 are opened inside the fixing ring 20. A locking rod 22 is slidably arranged in the mounting cavity 21. Two locking grooves 23 adapted to the two locking rods 22 are opened on the outer ring of the top of the cylindrical oil filter frame 13. A retaining ring 24 located in the mounting cavity 21 is fixedly connected to the locking rod 22. A spring 25 located in the mounting cavity 21 is also sleeved on the locking rod 22. The spring 25 is located on the side of the retaining ring 24 away from the locking groove 23. A pull block 26 is fixedly connected to the end of the locking rod 22 away from the locking groove 23.

[0023] Those skilled in the art will understand that the fixing ring 20 at the bottom of the cover 11 provides installation positioning for the cylindrical oil filter frame 13. During installation, the top of the cylindrical oil filter frame 13 is inserted into the fixing ring 20. Under the elastic force of the spring 25, the locking rod 22 in the mounting cavity 21 of the fixing ring 20 is pushed by the retaining ring 24 to insert the locking rod 22 into the locking groove 23 at the top of the cylindrical oil filter frame 13, thereby fixing the oil filter frame. During disassembly, the pull block 26 is pulled to drive the locking rod 22 to compress the spring 25 and disengage from the locking groove 23, so that the oil filter frame can be removed.

[0024] The spring 25 and the locking rod 22 work together to enable quick assembly and disassembly of the cylindrical oil filter frame 13 without the need for additional tools, making the operation convenient. The retaining ring 24 can limit the sliding stroke of the locking rod 22, preventing the spring 25 from being over-compressed or the locking rod 22 from falling off, thus improving the stability of the fixed structure. Example

[0025] Furthermore, a guide block 27 is fixedly connected to the top outer ring of the cylindrical oil filter frame 13, and a guide groove 28 adapted to the guide block 27 is provided at the bottom of the fixing ring 20.

[0026] Those skilled in the art will understand that, based on Embodiment 3, the guide block 27 on the outer ring of the top of the cylindrical oil filter frame 13 cooperates with the guide groove 28 at the bottom of the fixing ring 20. When installing the oil filter frame, the guide block 27 is first inserted into the guide groove 28 so that the locking groove 23 at the top of the oil filter frame is automatically aligned with the locking rod 22 inside the fixing ring 20.

[0027] The guiding function of guide block 27 and guide groove 28 prevents misalignment of locking groove 23 and locking rod 22 during installation, improves the installation efficiency and accuracy of oil filter frame, and reduces the rate of operational errors. Example

[0028] Furthermore, the agitation mechanism 10 includes a second motor 1001 fixedly connected to the outside of the oil tank 3. The output end of the second motor 1001 is fixedly connected to a rotating rod 1002 located inside the oil tank 3. Several agitation blades 1003 are evenly distributed on the rotating rod 1002.

[0029] Those skilled in the art will understand that the second motor 1001 of the stirring mechanism 10 is fixed on the outside of the oil tank 3, and its output end drives the rotating rod 1002 inside the oil tank 3 to rotate. The stirring blades 1003 evenly distributed on the rotating rod 1002 rotate synchronously with the rotating rod 1002 to stir the oil in the oil tank 3.

[0030] The evenly distributed stirring blades 1003 ensure uniform mixing of the oil, preventing localized sedimentation or uneven temperature. The external design of the second motor 1001 facilitates maintenance and avoids direct contact between the motor and the oil, thus improving the motor's service life and operational safety. Example

[0031] Furthermore, the anti-clogging component 14 includes a third motor 1401 fixedly connected to the center of the bottom of the cylindrical oil filter frame 13. The output end of the third motor 1401 is fixedly connected to a connecting plate 1402 located inside the cylindrical oil filter frame 13.

A protective shell 1404 located outside the third motor 1401 is also fixedly connected to the bottom of the cylindrical oil filter frame 13.

[0032] Those skilled in the art will understand that the third motor 1401 of the anti-clogging component 14 is fixed at the bottom center of the cylindrical oil filter frame 13, and its output end drives the connecting plate 1402 inside the oil filter frame to rotate. The two L-shaped scrapers 1403 on the outer ring of the connecting plate 1402 rotate synchronously with the connecting plate 1402. The horizontal plate of the L-shaped scraper 1403 is attached to the bottom wall of the inner side wall of the oil filter frame, and the vertical plate is attached to the inner side wall of the oil filter frame to scrape off the impurities attached to the wall surface of the oil filter frame. The protective shell 1404 at the bottom of the cylindrical oil filter frame 13 covers the third motor 1401 to prevent the oil from coming into direct contact with the motor.

[0033] The all-around scraping action of the L-shaped scraper 1403 can effectively prevent impurities from clogging the filter holes of the cylindrical oil filter frame 13, ensuring the oil filtration efficiency and smooth delivery; the protective shell 1404 protects the third motor 1401, preventing oil from corroding the motor and ensuring the long-term stable operation of the anti-clogging component 14.

[0034] The working principle and usage procedure of this device are as follows: Open the cover 18 of the oil replenishment port 12 at the top of the tank cover 11 to replenish the oil in the oil tank 3. During the replenishment process, the oil level can be observed through the liquid level observation port 17 and the liquid level line on the front side of the oil tank 3. After the liquid level reaches the preset height, close the cover 18. When replenishing the oil, impurities in the oil entering the oil tank 3 will be filtered by the cylindrical oil filter frame 13. At the same time, the third motor 1401 is started. The third motor 1401 drives the connecting plate 1402 and the L-shaped scraper 1403 to rotate. The horizontal and vertical plates of the L-shaped scraper 1403 respectively adhere to the inner bottom wall and inner side wall of the cylindrical oil filter frame 13, scraping away impurities in the filter holes to prevent clogging. If the environment... When the temperature is low, the heating rod 16 is activated to heat the oil. At the same time, the second motor 1001 is activated, which drives the rotating rod 1002 and the evenly distributed stirring blades 1003 to rotate, stirring the oil to make the oil temperature uniform and keep it in a flowing state, preventing it from cooling and solidifying. Then, the solenoid valve 19 is activated, which allows the oil in the oil tank 3 to enter the gear metering tank 5 through the oil delivery pipe 9 and the oil inlet 8 on the right side of the oil pump body 2. At the same time, the first motor 4 is activated, which drives the meshing metering gears 6 in the gear metering tank 5 to rotate. Through the meshing transmission of the metering gears 6, the oil is delivered from the oil outlet 7 on the left side of the oil pump body 2 to the filament bundle.
