Description

Technical Field

[0001] This utility model relates to the field of oil supply tank technology, and in particular to an oil supply tank for a texturing machine. Background Technology

[0002] Texturing machines are textile machinery used to process synthetic fiber filaments. They mainly use mechanical and thermal processes to give synthetic fiber filaments special properties such as bulkiness and elasticity during false twisting and stretching, thereby producing textured yarns with high added value. They are widely used in the production of various fabrics in the textile industry to meet the requirements of different clothing, home textiles and other products for fabric performance and texture.

[0003] Currently, many texturing machines on the market are equipped with lubricating oil supply tanks that commonly use ball valves to control the oil level. However, ball valves are prone to damage after prolonged use. When a ball valve fails, the oil level in the tank may become too high, causing lubricating oil to overflow. This not only wastes lubricating oil and increases production costs but also pollutes the working environment around the texturing machine and may even pose a safety hazard. Conversely, the oil level may become too low, resulting in insufficient lubrication for the mechanical parts of the texturing machine. This exacerbates wear between parts, reduces the machine's efficiency and stability, and in severe cases, may even lead to equipment failure, disrupting the entire production process. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing ball valves are prone to damage after prolonged use. When a ball valve is damaged, the oil level in the tank may become too high, causing lubricating oil to overflow. This not only wastes lubricating oil and increases production costs, but also pollutes the working environment around the texturing machine and may even pose a safety hazard. Conversely, the oil level may become too low, resulting in insufficient lubrication for the mechanical parts of the texturing machine, exacerbating wear between components, reducing the working efficiency and stability of the texturing machine, and in severe cases, causing equipment failure and affecting the normal operation of the entire production process. Therefore, this invention proposes a lubricating oil supply tank for a texturing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lubricating oil supply tank for a texturing machine includes an oil tank, a transparent sealing cover at the opening of the oil tank, a float rotatably mounted inside the oil tank, a trigger rod fixedly mounted on the connecting rod of the float, a triggering mechanism mounted on the inner wall of the oil tank, and the movable end of the trigger rod facing the triggering mechanism.

[0007] The top of the transparent sealing cover is provided with a fixing tube, a valve is installed on the fixing tube, and a control mechanism is provided on the valve;

[0008] The triggering mechanism is connected to an external control mechanism via an electric wire, and the control mechanism controls the opening and closing of the valve through the signal from the triggering mechanism.

[0009] Preferably, the triggering mechanism includes a fixed sleeve, a spring, a movable block, a trigger pin, and a micro switch. The fixed sleeve is fixedly disposed on the inner wall of the fuel tank, the movable block is slidably disposed within the fixed sleeve, one end of the spring is fixedly connected to the inner wall of the fixed sleeve, and the other end is connected to the movable block. The trigger pin is fixedly disposed on the side of the movable block facing the inside of the fixed sleeve, the micro switch is disposed within the fixed sleeve and corresponds to the position of the trigger pin, and the micro switch is connected to the control mechanism through a wire passing through the outer wall of the fuel tank.

[0010] Preferably, a sealing gasket is provided on the outer side of the movable block to prevent lubricating oil from seeping into the interior of the fixed sleeve.

[0011] Preferably, the control mechanism includes a servo motor, a fixed plate, a worm gear, and a worm wheel. The fixed plates are arranged in pairs and fixed to the transparent sealing cover. The servo motor is fixedly installed on the fixed plate. The worm gear is rotatably arranged between the fixed plates and connected to the output shaft of the servo motor. The worm wheel is fixedly fitted onto the valve stem of the valve and meshes with the worm gear.

[0012] Preferably, the contact surface between the end of the trigger rod and the moving block is an inclined structure, which is used to convert the rotational motion of the float into the linear displacement of the moving block.

[0013] Preferably, an angle sensor is provided between the worm gear and the valve stem to provide feedback on the valve opening to the servo motor.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In use, this invention can monitor the oil tank level in real time through the linkage design of the float and the trigger mechanism. When the level is too high, the control mechanism automatically reduces the valve flow to prevent lubricating oil from overflowing, thus reducing waste and pollution to the production environment. When the level is too high, the control mechanism automatically increases the valve flow to prevent lubricating oil from overflowing, thus reducing waste and pollution to the production environment. Compared with traditional ball valves that rely on manual adjustment, this solution has a high degree of automation and can accurately control the oil supply, reducing the risk of lubricating oil leakage due to uncontrolled level.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-4 A lubricating oil supply tank for a texturing machine includes an oil tank 1. A transparent sealing cover 2 is provided at the opening of the oil tank 1. The transparent sealing cover 2 is made of polycarbonate material, which has both high light transmittance and oil resistance, making it easy to observe changes in oil level. The edge of the sealing cover is fitted with a silicone sealing ring and the opening of the oil tank to ensure a complete seal while enabling repeated opening.

[0023] The oil tank 1 is equipped with a rotating float 3. The float 3 is made of hollow stainless steel and has a built-in counterweight adjustment cavity, which can adjust the buoyancy parameters according to different oil densities.

[0024] A trigger rod 4 is fixedly installed on the connecting rod of the float 3. A trigger mechanism 5 is installed on the inner wall of the oil tank 1. The trigger mechanism 5 includes a fixed sleeve 10, a spring 11, a moving block 12, a trigger needle 13, and a micro switch 14. The fixed sleeve 10 is fixedly installed on the inner wall of the oil tank 1. The moving block 12 is slidably installed inside the fixed sleeve 10. One end of the spring 11 is fixedly connected to the inner wall of the fixed sleeve 10, and the other end is connected to the moving block 12. The trigger needle 13 is fixedly installed on the side of the moving block 12 facing the inside of the fixed sleeve 10. The micro switch 14 is installed inside the fixed sleeve 10 and corresponds to the position of the trigger needle 13. The micro switch 14 is connected to the control mechanism 8 through the wire 9 through the outer wall of the oil tank 1. The movable end of the trigger rod 4 is positioned opposite the trigger mechanism 5.

[0025] A fixed tube 6 is provided on the top of the transparent sealing cover 2. A valve 7 is installed on the fixed tube 6. A control mechanism 8 is provided on the valve 7. The control mechanism 8 includes a servo motor 15, a fixed plate 16, a worm gear 17 and a worm wheel 18. The fixed plates 16 are arranged in pairs and fixed on the transparent sealing cover 2. The servo motor 15 is fixedly installed on the fixed plate 16. The worm gear 17 is rotatably arranged between the fixed plates 16 and connected to the output shaft of the servo motor 15. The worm wheel 18 is fixedly fitted on the valve stem of the valve 7 and meshes with the worm gear 17.

[0026] The triggering mechanism 5 is connected to the control mechanism 8 via the wire 9. The control mechanism 8 controls the opening and closing of the valve 7 via the signal from the triggering mechanism 5.

[0027] It should be noted that the servo motor 15, micro switch 14, and valve 7 are existing technologies in this field. The specific model and specifications to be used need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts existing technologies in this field, so it will not be elaborated here. All of them can be powered by external devices and controlled to open and close.

[0028] Furthermore, a sealing gasket 19 is provided on the outer side of the movable block 12 to prevent lubricating oil from seeping into the interior of the fixed sleeve 10.

[0029] The sealing gasket 19 is made of fluororubber, which ensures both the protection level and the contact pressure between the trigger pin 13 and the micro switch 14.

[0030] Furthermore, the contact surface between the end of the trigger rod 4 and the moving block 12 is an inclined structure, which is used to convert the rotational motion of the float 3 into the linear displacement of the moving block 12.

[0031] Among them, the trigger rod 4 is dynamically balanced to ensure that it can rotate smoothly when the oil fluctuates. The specially designed inclined trigger rod 4 adopts a 45° tilt structure, which can convert the rotation angle of the float 3 into linear displacement, significantly improving the sensitivity of liquid level detection.

[0032] Furthermore, an angle sensor is installed between the worm gear 18 and the valve stem of the valve 7 to provide feedback on the valve opening to the servo motor 15.

[0033] Among them, valve 7 is equipped with a high-precision worm gear 18 and worm 17 transmission assembly, which, together with an angle sensor with a resolution of 0.1°, can achieve precise control of the opening degree.

[0034] Working principle:

[0035] When the oil level in tank 1 drops, float 3 rotates as the oil level decreases, causing trigger rod 4 to swing. The inclined structure of trigger rod 4 pushes moving block 12 to slide inward, compressing spring 11, causing trigger needle 13 to contact micro switch 14, sending a low oil level signal. Micro switch 14 transmits the signal to control mechanism 8 through wire 9, servo motor 15 starts, drives worm gear 17 to rotate, drives worm wheel 18 and valve stem of valve 7 to rotate, gradually opening valve 7, and external oil circuit begins to replenish oil.

[0036] An angle sensor monitors the valve opening in real time and feeds back the data to the servo motor 15 to ensure that the oil supply speed matches the consumption. When the oil level rises, the float 3 resets, the trigger rod 4 disengages from the moving block 12, the spring 11 pushes the moving block 12 back to its original position, the micro switch 14 is turned off, and the servo motor 15 stops or reduces the opening to achieve closed-loop control.

[0037] The sealing gasket 19 prevents lubricating oil from seeping into the retaining sleeve 10, ensuring the long-term reliability of the triggering mechanism 5. The transparent sealing cover 2 facilitates manual inspection of the oil level. The entire system has the ability to prevent spillage and provide precise oil supply, making it suitable for the continuous lubrication needs of texturing machines.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
