Description

Technical Field

[0001] This invention relates to the field of textile machine lubrication technology, and in particular to a modular electronically controlled automatic lubrication system. Background Technology

[0002] Lubrication management is one of the most important tasks in the maintenance of cotton spinning equipment. It plays a crucial role in reducing the equipment's internal power consumption, alleviating friction in moving parts, and eliminating or mitigating damage to contact surfaces caused by friction. Therefore, proper lubrication management is a prerequisite for ensuring stable and efficient equipment operation.

[0003] Currently, refueling is mainly done manually, which is not only time-consuming and labor-intensive, but also prone to untimely refueling and inability to maintain constant internal oil pressure. In addition, when there are multiple cotton spinning machines, modular oiling cannot be carried out through a single oil tank, and multiple oil tanks need to be filled separately, resulting in high equipment installation costs. Summary of the Invention

[0004] The technical problem that this invention aims to solve is that current oiling is mainly done manually, which is not only time-consuming and labor-intensive, but also prone to untimely oiling and inability to maintain constant internal oil pressure. Furthermore, when dealing with multiple cotton spinning equipment, modular oiling cannot be performed using a single oil tank, requiring multiple oil tanks for separate oiling, resulting in high equipment installation costs.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a modular electronically controlled automatic refueling system, including a liquid supply system, a control system and a liquid delivery system;

[0006] The liquid supply system includes an oil storage tank, a regulating valve installed on the oil drain pipe at the lower end of the oil storage tank, a double U-shaped oil guide pipe installed on the oil outlet at the lower end of the regulating valve, and an oil chamber connected to the inside of the double U-shaped oil guide pipe.

[0007] The control system includes a top sealing liquid guide nozzle fixedly installed on the top surface of the oil chamber by a bracket, a hollow structure buoy set inside the oil chamber, a valve needle closing bracket fixedly installed on the upper end of the hollow structure buoy, and a modular lateral connector on the outer side of the oil chamber.

[0008] The infusion system includes a constant low-pressure oil tank installed on a textile machine, a lateral support fixed to the outer side of the oil tank, an outer fixing frame welded and fixed to the lateral support, an electrically controlled adjustment bracket, and a lateral hose for connecting the modular lateral connector and the constant low-pressure oil tank.

[0009] The oil chamber includes a main tank for storing oil and an upper cover installed at the opening at the top of the main tank.

[0010] The valve needle closing bracket is inserted into the side bracket via an assembly shaft on one side and is movably assembled with the side bracket. The valve needle closing bracket is equipped with a top sealing head that mates with the top sealing liquid guide nozzle.

[0011] The outer side of the oil chamber is provided with a lateral assembly through hole for assembling a modular lateral joint. The modular lateral joint includes a first annular assembly cover, a second annular assembly cover, a lateral threaded pipe fixedly assembled inside the lateral assembly through hole, a tee threaded assembly pipe threadedly assembled on the side wall of the second annular assembly cover, and a threaded assembly bend threadedly assembled on the outside of the tee threaded assembly pipe.

[0012] The constant low pressure oil tank assembly end side wall is fixed with an external threaded connector that communicates with the interior. Both ends of the lateral hose are axially fixed with internal threaded connectors. The lateral hose is fixedly connected to the oil chamber and the constant low pressure oil tank by the internal threaded connectors at both ends respectively sleeved on the outside of the threaded assembly bend and the external threaded connector.

[0013] The electrically controlled adjustment bracket includes an upper electrically controlled telescopic support rod installed on the upper end of the outer fixed frame, a bottom adjustment frame axially fixed to the bottom of the telescopic section of the upper electrically controlled telescopic support rod, and a first assembly crossbar and a second assembly crossbar fixed inside the bottom adjustment frame.

[0014] A lateral mounting frame that cooperates with the first mounting crossbar is fixedly mounted on the outer side of the constant low pressure oil tank, and a lateral guide rail with a built-in elastic slider is fixedly mounted on the outer side of the constant low pressure oil tank.

[0015] An external limiting hook that cooperates with the second assembly crossbar is fixedly mounted on the outer side of the elastic slider.

[0016] An electronically controlled correction strut is fixedly mounted on the inner side of the bottom adjustment frame, and an electronic level controller for controlling the electronically controlled correction strut is fixedly mounted on the upper surface of the constant low pressure oil tank.

[0017] The top sealing liquid guide nozzle includes a bottom connector fixed at the lower end of the double U-shaped oil guide tube, an internal connector fixed on the upper cover, and a replaceable metal filter screen fixed inside the internal connector.

[0018] The beneficial effects of this invention are:

[0019] (1) The modular electronic control automatic refueling system of the present invention adopts an automated operation mode, which eliminates the need for manual operation, greatly reduces the difficulty of manual operation and improves the timeliness of operation, saving time and effort;

[0020] (2) By adopting an automatic oil level height, the oil level inside the constant low pressure oil tank is kept consistent, thus ensuring the stability and consistency of internal oil suction;

[0021] (3) The constant low pressure oil tank is connected by a modular assembly method, which can connect and assemble multiple cotton spinning equipment as needed, and reduce equipment costs by coordinating oiling.

[0022] (4) By fixing a lateral mounting frame that cooperates with the first mounting crossbar on the outer side of the constant low pressure oil tank, and elastically mounting an external limiting hook that cooperates with the second mounting crossbar, the constant low pressure oil tank can be quickly loaded and unloaded, and can automatically adjust the level and height, thereby improving applicability and facilitating control.

[0023] (5) The connection between the oil storage tank and the oil chamber can be automatically controlled by the internal oil level, which improves safety;

[0024] (6) By setting a detachable filter mechanism at the interface end, the filtration effect is greatly improved and the maintenance cost is reduced. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Figure 1 , Figure 2 , Figure 3 and Figure 4The illustrated modular electronically controlled automatic refueling system includes a liquid supply system, a control system, and a liquid delivery system.

[0033] The liquid supply system includes an oil storage tank 1, a regulating valve 2 installed on the oil drain pipe at the lower end of the oil storage tank 1, a double U-shaped oil guide pipe 3 installed on the oil outlet at the lower end of the regulating valve 2, and an oil chamber 4 connected to the inside of the double U-shaped oil guide pipe 3;

[0034] The control system includes a top sealing liquid guide nozzle 5 fixedly installed on the top surface of the oil chamber 4 by a bracket, a hollow structure buoy 6 set inside the oil chamber 4, a valve needle closing bracket 7 fixedly installed on the upper end of the hollow structure buoy 6, and a modular lateral connector 8 on the outer surface of the oil chamber 4.

[0035] The infusion system includes a constant low-pressure oil tank 9 installed on a textile machine, a lateral support fixed to the outer side of the oil chamber 4, an outer fixing frame 10 welded and fixed to the lateral support, an electrically controlled adjustment bracket 11, and a lateral hose 12 for connecting the modular lateral connector 8 and the constant low-pressure oil tank 9.

[0036] Simply add the spindle-specific oil to the oil storage tank 1, and the oil flows through the lower drain pipe into the regulating valve 2. After passing through the regulating valve 2, it enters the oil chamber 4. Once the oil level rises to a certain height, the hollow structure float 6 rises, lifting the valve needle closing bracket 7. Simultaneously, the valve needle closing bracket 7 and the top sealing guide nozzle 5 seal each other, preventing the oil level from rising further. When the oil level in the constant low-pressure oil tank 9 drops, the hollow structure float 6 descends, and the top sealing guide nozzle 5 reopens. When the oil level is reached, the top sealing guide nozzle 5 closes again, maintaining the oil level. This controls the oil level in the constant low-pressure oil tank 9, preventing both overflow and insufficient oil. It replaces the tedious work of manual refueling and solves the problems of either overfilling or underfilling during manual refueling.

[0037] To facilitate assembly and closure, the oil chamber 4 includes a main tank for storing oil and an upper cover installed at the opening position at the upper end of the main tank.

[0038] To facilitate flip-closing, the valve needle closing bracket 7 is inserted into the side bracket via an assembly shaft on one side and is movably assembled with the side bracket. The valve needle closing bracket 7 is equipped with a top sealing head 13 that mates with the top sealing liquid guide nozzle 5.

[0039] To facilitate modular assembly and fixing, a lateral assembly through hole for assembling the modular lateral connector 8 is provided on the outer side of the oil chamber 4. The modular lateral connector 8 includes a first annular assembly cover 81 and a second annular assembly cover 82 fixedly assembled inside the lateral assembly through hole, a lateral threaded pipe 83 fixed on the side wall of the second annular assembly cover 82, a three-way threaded assembly pipe 84 threadedly assembled on the lateral threaded pipe 83, and a threaded assembly bend 85 threadedly assembled on the outside of the three-way threaded assembly pipe 84.

[0040] The number of constant low-pressure oil tanks 9 can be controlled by increasing the number of tee threaded assembly pipes 84.

[0041] To facilitate the lateral threaded assembly and fixation, an external threaded connector that communicates with the interior is fixed on the side wall of the assembly end of the constant low pressure oil tank 9. Both ends of the lateral hose 12 are axially fixed with internal threaded connectors. The lateral hose 12 is fixedly connected to the oil chamber 4 and the constant low pressure oil tank 9 by the internal threaded connectors at both ends respectively sleeved on the outside of the threaded assembly bend 85 and the external threaded connector.

[0042] The internal threaded connector at one end of the lateral hose 12 is threadedly fixed to the external threaded connector at the assembly end of the constant low pressure oil tank 9, and the internal threaded connector at the other end is threadedly fixed to the tee threaded assembly pipe 84 or the threaded assembly bend pipe 85.

[0043] To facilitate lateral assembly and adjustment of lifting, the electrically controlled adjustment bracket 11 includes an upper electrically controlled telescopic support rod 111 mounted on the upper end of the outer fixed frame 10, a bottom adjustment frame 112 axially fixed to the bottom of the telescopic section of the upper electrically controlled telescopic support rod 111, and a first assembly crossbar 113 and a second assembly crossbar 114 fixed inside the bottom adjustment frame 112.

[0044] The upper electrically controlled telescopic support rod 111 is existing technology, and the height of the bottom adjustment frame 112 is adjusted by telescoping.

[0045] To facilitate lateral assembly and lateral adjustment, a lateral assembly fixing frame 91 that cooperates with the first assembly crossbar 113 is fixedly mounted on the outer side of the constant low pressure oil tank 9, and a lateral guide rail 93 with a built-in elastic slider 92 is fixedly mounted on the outer side of the constant low pressure oil tank 9.

[0046] The elastic slider 92 includes a slider that is slidably mounted inside the side guide rail 93 and a compression spring mounted on the slider.

[0047] To facilitate lateral limiting and locking, an external limiting hook 94 that cooperates with the second assembly crossbar 114 is fixedly mounted on the outer side of the elastic slider 92.

[0048] The constant low pressure oil tank 9 is first connected by the side assembly fixing frame 91 on the first assembly crossbar 113, and then the external limiting hook 94 is elastically fitted on the second assembly crossbar 114. At this time, the elastic extrusion force can not only ensure the shock absorption of the constant low pressure oil tank 9, but also ensure that the constant low pressure oil tank 9 is fixed inside the bottom adjustment frame 112.

[0049] When disassembly is required, simply press the external limiting hook 94 upwards to separate the external limiting hook 94 from the second assembly crossbar 114, and the constant low pressure oil tank 9 can be separated from the second assembly crossbar 114, and the constant low pressure oil tank 9 can be quickly separated.

[0050] In order to facilitate the leveling of the constant low pressure oil tank 9, an electronically controlled correction strut 115 is fixedly mounted on the inner side of the bottom adjustment frame 112, and an electronic level controller 14 for controlling the electronically controlled correction strut 115 is fixedly mounted on the upper surface of the constant low pressure oil tank 9.

[0051] Both the electronic level controller 14 and the electronically controlled correction strut 115 are existing technologies. The electronic level controller 14 monitors the horizontal angle of the constant low-pressure oil tank 9. When the constant low-pressure oil tank 9 is lower on the left and higher on the right, it controls the extension of the electronically controlled correction strut 115 to compress the inner side of the outer fixed frame 10, thereby controlling the bottom adjusting frame 112 to drive the constant low-pressure oil tank 9 to rotate clockwise for correction. When the constant low-pressure oil tank 9 is higher on the left and lower on the right, it controls the retraction of the electronically controlled correction strut 115 to control the bottom adjusting frame 112 to tighten to the right, thereby controlling the bottom adjusting frame 112 to drive the constant low-pressure oil tank 9 to rotate counterclockwise for correction.

[0052] By adjusting the level of the constant low-pressure oil tank 9, the oil absorption stability and consistency of the internal oil-absorbing cotton thread can be guaranteed.

[0053] To facilitate oil inlet filtration and subsequent maintenance and cleaning, the top sealing liquid guide nozzle 5 includes a bottom connector 51 fixed at the lower outlet of the double U-shaped oil guide tube 3, an internal connector 52 fixed on the upper cover, and a replaceable metal filter screen 53 fixed inside the internal connector 52.

[0054] The bottom connector 51 is fixedly connected to the internal connector 52 by inserting it into the upper opening of the internal connector 52.

[0055] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
