Description

Technical Field

[0001] This utility model relates to a precision yarn oiling device, belonging to the technical field of spinning equipment. Background Technology

[0002] In the winding process of some special yarns, it is necessary to perform processes such as waxing and polishing, oiling and lubrication, and applying antistatic agents to prevent pilling. The wax blocks are generally solid, while the oils or antistatic agents are generally in the form of pastes or viscous liquids. This waxing or oiling process can reduce yarn fuzz and damage, and improve the yarn's luster and storage time.

[0003] Older oiling devices are typically roller-dip type, where the roller slowly rotates in an oil box to pick up grease from the box and lubricate the yarn it passes through. However, this type of device is prone to inaccurate control of the amount of grease applied, which may result in insufficient grease leading to excessive fuzz or excessive grease causing the grease to be flung out of the yarn and contaminate the equipment and production environment. Moreover, this type of device is only suitable for oil-based lubricants that are easy to pick up and have good fluidity, and is not suitable for paste-like greases with poor fluidity. Therefore, this old-fashioned oiling device has a narrow range of compatibility with different types of yarn substrates. Utility Model Content

[0020] like Figures 1-4 As shown, a precision yarn oiling device includes an oiling housing 04; a PLC panel touch screen 10 is installed on the oiling housing 04. The PLC panel touch screen 10 is used for setting pump parameters, including the oil feed rate. The oil inlet housing 04 includes a main housing 041 and a back plate 042, which serves as the main body for supporting components. Inside, there are an oil inlet device with a regulating valve 01, a small servo motor 02, an embedded oil circuit delivery module 03, a safety overflow type ceramic oil outlet assembly 06, and a gear pump assembly 08. The oil inlet device 01 with regulating valve is connected to the embedded oil delivery module 03 on one side; An oil passage hole is provided in the middle of the embedded oil passage delivery module 03, which is connected to the oil outlet hole of the oil inlet device 01 with regulating valve; a gear pump assembly 08 is provided in the embedded oil passage delivery module 03; the gear pump assembly 08 is connected to the oil inlet device 01 with regulating valve through an oil passage pipe channel; the gear pump assembly 08 is connected to the safety overflow ceramic oil outlet assembly 06 through an oil passage pipe channel. A small servo motor 02 is connected to one side of the gear pump assembly 08. The gear pump assembly 08 is installed inside the embedded oil delivery module 03, and it pumps out grease or other lubricants through the meshing of gears. The safety overflow type ceramic oil outlet assembly 06 is equipped with an oiling yarn 12.

[0021] In this embodiment, the oil inlet device 01 with regulating valve includes an oil box isolation connector 011, a connector baffle 012, a connector valve core 013, a check valve core 014, and a heating tube 015; the oil inlet device 01 with regulating valve is used for lubricant introduction, and a control valve is provided inside to control the lubricant flow rate.

[0022] In this embodiment, a small servo motor 02 is installed in a hole on the output gear of the gear pump assembly 08. It drives the gear pump assembly 08 to rotate and pump oil through the control of the PLC panel touch screen 10. The PLC panel touch screen 10 can edit program parameters to control the start and stop of the small servo motor 02 and adjust its rotation speed.

[0023] In this embodiment, refer to Figure 7The safety overflow type ceramic nozzle assembly 06 includes an overpressure relief ceramic main nozzle 061, an overflow conduction type ceramic auxiliary nozzle 062, a small compression spring 063, a piston type oil guide 064, and a mounting base. The rear of the mounting base is provided with multiple passages. The front end of the middle passage is connected to an overpressure relief ceramic main oil nozzle 061, a small compression spring 063, and a piston-type oil guide 064, and the rear end is connected to the gear pump assembly 08 through an oil pipe-type channel. Secondary guide passages are led out from the top and bottom of the middle passage. An overflow-conducting ceramic auxiliary oil nozzle 062 is installed at the end of the secondary guide passage.

[0024] In this embodiment, a flow sensor is installed on the oil pipe channel of the gear pump assembly 08 and the safety overflow ceramic oil outlet assembly 06, which is used to detect and provide feedback on the flow rate of lubricant through the internal pipeline.

[0025] In this embodiment, a splash-proof cover plate 05 is also included. The splash-proof cover plate 05 is connected to the front end face of the oiling housing 04 by a hinge. It is used to block oil droplets or grease that are carried out, flung out, or splashed out by the yarn at high speed.

[0026] In this embodiment, a transparent sealing panel cover 09 is also included. The transparent sealing panel cover 09 is located on the right side of the upper oil housing 04. Its inner cover surface covers the outside of the gear pump assembly 08 and is fixed on the embedded oil circuit delivery module 03, thereby forming a transparent sealing cavity.

[0027] In this embodiment, the upper and lower ends of the safety overflow type ceramic oil nozzle assembly 06 are provided with concave yarn guide ceramics 07, which are used to help the oiled yarn 12 slide smoothly through.

[0028] The most common oiling methods on the market have the following drawbacks: First, when the yarn passes through quickly, because the rotation speed is not very high, not all segments of the yarn can be coated with the oil, resulting in uneven oiling. Second, if the rotation speed is very high, the oiling turntable will carry out a lot of oil due to the high viscosity of the oil. When the yarn passes through quickly upwards, the excessive amount of oil will cause the excess oil to be splashed out, resulting in a lot of spotted oil on the equipment and even contaminating the yarn in other spindles.

[0029] Therefore, this device uses a PLC control board to control a motor-driven gear pump to pump oil to the oil outlet. The amount of oil to be pumped depends on the linear speed of the yarn passing through the oil outlet and the pump flow rate (for example, if the process specification requires 2kg of oil for 100 rolls of yarn, then the amount of oil required per roll = 2000g / 100 rolls = 20g / roll. Assuming the total length of one roll of yarn is 8000 meters and the yarn winding linear speed is 400 meters / min, then the amount of oil required for the process of 8000 / 400 (i.e., the yarn is wound in 20 minutes) is 20g, and the amount of oil required per minute is 20g / 20min = 1g). Based on this parameter, the motor speed can be set on the touch panel of the PLC control board to control the flow rate of the gear pump (the pump displacement and volumetric efficiency are fixed), so that the actual oil output of the pump meets the parameter value of 1g / min (the actual volume of lubricant v can be calculated from m / ρ).

[0030] Reference Figure 4 and Figure 5 The schematic diagram of the oil circuit shows that this device mainly consists of the following core components: PLC panel touch screen: used to set oiling parameters (such as pump oil volume, motor speed, etc.) to achieve precise control.

[0031] Oil inlet device with regulating valve: introduces lubricant (grease or antistatic agent), and regulates the flow rate through the internal valve core, supporting paste or liquid lubricant.

[0032] Small servo motor: drives the gear pump assembly. Its speed is controlled by the PLC program and directly affects the pump oil volume.

[0033] Gear pump assembly: Pressure is generated through gear meshing to pump lubricant from the inlet to the outlet.

[0034] Safety overflow type ceramic oil outlet assembly: The main oil outlet (061) is responsible for even oil distribution, and the auxiliary oil outlet (062) overflows excess lubricant when the pressure is too high to prevent blockage or splashing.

[0035] Flow sensor: Monitors the flow rate of lubricant in the pipeline in real time and feeds it back to the PLC system to dynamically adjust the pump speed.

[0036] Splash guard: blocks oil droplets thrown out by high-speed yarn, keeping the equipment clean.

[0037] 2. Workflow Parameter settings Users input process parameters (such as yarn length, target oiling amount, linear speed, etc.) through the PLC touch screen.

[0038] The PLC automatically calculates the required amount of oil to be pumped (for example, if each roll of yarn needs 20g of oil and the yarn winding speed is 400 meters / minute, then the oil pumping amount is set to 1g / minute).

[0039] Lubricant delivery The lubricant enters from the oil inlet device 01 with a regulating valve, and after the initial flow is controlled by the regulating valve, it flows into the embedded oil circuit delivery module 03.

[0040] A small servo motor 02 drives a gear pump 08 to rotate, which pressurizes and pumps the lubricant to the ceramic oil outlet assembly 06.

[0041] Precise lubrication and overflow protection: Normal state: Lubricant is evenly seeped from the main oil nozzle (061) through the piston-type oil guide (064) and coated on the passing yarn.

[0042] Overpressure condition: If the pump oil volume is too large instantaneously, the pressure pushes the piston (064) to compress the spring (063), the auxiliary oil nozzle (062) channel opens, and the excess lubricant overflows to the recovery device to avoid contaminating the equipment.

[0043] The flow sensor monitors the actual pumped oil volume in real time, compares it with the PLC set value, and automatically adjusts the servo motor speed to ensure that the oil supply error is ≤0.5g / km (4-5 times more accurate than traditional devices). If the high-speed passing yarn carries away excess grease, the splash guard and concave yarn-passing ceramic 07 can effectively block splashing, and the transparent sealed panel makes it easy to observe the internal operating status.

[0044] Technical Advantages: High Compatibility: Adaptable to various lubricants, including pastes and liquids, solving the problem of traditional roller-type devices being unsuitable for high-viscosity greases. Intelligent Control: PLC programming enables parameterized operation, supporting customized oiling needs for different yarn specifications. Strong Stability: Overflow protection mechanism and flow feedback system ensure uniform oiling and reduce scrap rate. Environmentally Friendly and Clean: Enclosed structure and splash-proof design reduce grease contamination, meeting the requirements of modern production environments.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
