Description

Technical Field

[0001] This utility model relates to the field of spinning machine technology, and in particular to a lubrication device for the spindle seat of a spinning machine. Background Technology

[0002] A ring spinning frame is a spinning machine that processes semi-finished roving or sliver through drafting, twisting, and winding to ultimately produce fine yarn bobbins. It is a key machine in spinning production, and the output and quality of the fine yarn directly reflect the quality of each step in the spinning process. In the textile industry, as a critical piece of equipment, the lubrication condition of the ring spinning frame's spindle directly affects the machine's operating efficiency, service life, and the quality of the yarn produced.

[0003] Existing ring spinning machine spindles present a series of problems in installation, oil change maintenance, and manufacturing. During installation, the disassembly and installation of the spindle holder nut are cumbersome, representing a wasteful and non-value-adding installation operation from a lean manufacturing perspective. For oil change maintenance, each spindle-disc assembly must be manually removed, and old oil must be drawn from the bearing holes on the needle rollers using tools. This is not only inconvenient but also prone to causing dirt to stick to the spindle-disc assembly, deformation from impacts, and inaccurate oil filling amounts and inconsistent lubrication levels. In the manufacturing process, the independent structural units of the existing spindle holders result in low machining efficiency, making it difficult to fully utilize the continuous processing capabilities of automated equipment.

[0004] Existing technologies for ring spinning frame spindle lubrication are insufficient to meet the growing demands of the textile industry for high-efficiency and high-quality production, whether in terms of ease of operation, completeness of the lubrication system, overall equipment operating efficiency, or maintenance cost control. There is an urgent need for a new type of ring spinning frame spindle lubrication device to solve these problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing spinning machines, such as cumbersome lubrication operations and low lubrication effect, and to provide a lubrication device for the spindle seat of a spinning machine.

[0006] This utility model is achieved through the following technical solution: a lubrication device for the main shaft seat of a spinning frame, including a frame rib, an oil storage chamber inside the frame rib, an oil inlet communicating with the oil storage chamber on the side of the frame rib away from the frame, and an oil outlet communicating with the oil storage chamber on the side of the frame rib closer to the frame; an oil injection mechanism is connected to the frame rib through the oil inlet, the oil injection mechanism is connected to an oil injection pipe through a quick connector, and the oil injection pipe is connected to an external oil source through a quick connector; an oil delivery mechanism is connected to the frame rib through the oil outlet, the oil delivery mechanism is connected to an oil delivery pipe through a quick connector, and the oil delivery pipe is connected to the main shaft seat through a quick connector. This utility model, by setting an oil storage chamber and matching oil inlet and outlet structures in the frame rib, and connecting the oil injection and delivery mechanisms, achieves convenient and efficient lubrication of the main shaft seat of the spinning frame, improving the convenience of lubrication operation.

[0007] A further improvement of this invention is that the oil injection mechanism includes a support pipe connected to the oil inlet. The top inner part of the support pipe is a threaded section, and a quick-connect pipe is screwed onto the support pipe through the threaded section. The bottom inner part of the support pipe is an oil delivery section, which is vertically connected to the threaded section. The diameter of the threaded section is smaller than that of the oil delivery section, forming a stepped structure. A sealing component is installed inside the oil delivery section. The sealing component is used in the oil injection mechanism. When the quick-connect pipe is fully engaged with the threaded section, the bottom end of the quick-connect pipe can trigger the sealing component, thus opening the oil injection mechanism. The oil injection mechanism, with its stepped structure of the threaded section and oil delivery section and the sealing component, only opens the oil injection channel when the quick-connect pipe is fully engaged, effectively preventing accidental oil leakage.

[0008] A further improvement of this invention is that the sealing assembly includes a sealing plate with a diameter larger than the threaded section and smaller than the oil delivery section. A sealing spring is connected to the bottom side of the sealing plate. The sealing spring is connected to a support frame, which is fixed to the inner bottom of the oil delivery section. The sealing spring ensures that the sealing plate always seals the bottom side of the threaded section, thus keeping the oil injection mechanism always closed. The sealing assembly, utilizing the sealing plate, sealing spring, and support frame, tightly seals the bottom side of the threaded section under normal conditions, ensuring that the oil injection mechanism remains closed when not in use, thereby enhancing the sealing performance and reliability of the oil injection mechanism.

[0009] A further improvement of this utility model is that a sealing groove corresponding to the sealing plate is provided at the top of the oil conveying section, and the sealing plate is placed inside the sealing groove; the threaded section, the sealing groove, and the oil conveying section are connected vertically to form a multi-stage stepped structure. The sealing groove at the top of the oil conveying section, forming a multi-stage stepped structure with the threaded section and the oil conveying section, improves the sealing effect of the sealing plate and further optimizes the sealing performance of the oil injection mechanism.

[0010] A further improvement of this invention is that the top of the quick-connect pipe is connected to an external oil source via a quick coupling, the bottom of the quick-connect pipe is screwed to a threaded section, and the bottom outer wall of the quick-connect pipe is provided with several auxiliary oil ports. The auxiliary oil ports at the bottom of the quick-connect pipe increase the flow path of the oil during injection, improve injection efficiency, and ensure that the oil enters the oil storage chamber more smoothly.

[0011] A further improvement of this utility model is that a sealing plate capable of pressing the top side of the support tube is provided on the outer side of the quick-connect pipe. When the sealing plate presses the top side of the support tube, the bottom end of the quick-connect pipe presses the sealing plate downward, so that the sealing plate can move downward out of the sealing groove. When the sealing plate presses the top side of the support tube, the bottom end of the quick-connect pipe can press the sealing plate, which is simple to operate and can accurately control the opening and closing of the oil injection mechanism, improving the controllability of the oil injection operation.

[0012] A further improvement of this invention is that the oil delivery mechanism includes a vertical pipe and a horizontal pipe, one side of which is connected to the horizontal pipe, and the vertical pipe and the horizontal pipe communicate with each other; the top of the vertical pipe is connected to the oil outlet, and the horizontal pipe is connected to the oil delivery pipe via a quick connector. The oil delivery mechanism, with its interconnected vertical and horizontal pipes, facilitates the connection between the oil outlet and the oil delivery pipe, providing a reasonable channel for oil delivery to the spindle seat and ensuring the smooth operation of the lubrication system.

[0013] A further improvement of this invention is that a filter unit is installed inside the vertical tube, and a sealing cap is screwed to the bottom side of the vertical tube. The filter unit and sealing cap inside the vertical tube can filter the oil entering the oil delivery pipe, preventing impurities from entering the spindle seat, protecting the normal operation of the spindle seat, and extending its service life.

[0014] A further improvement of this utility model is that the filter unit includes an annular limiting plate and a filter screen. The annular limiting plate is located at the inner top of the vertical tube, and an annular support plate corresponding to the annular limiting plate is provided at the opening of the filter screen. A helical spring is sleeved on the outside of the filter screen, and the helical spring enables the annular support plate to press against the annular limiting plate. The annular limiting plate, annular support plate, filter screen, and helical spring of the filter unit cooperate with each other to effectively filter oil impurities, and the helical spring ensures the stability of the filter structure, improving the filtration effect and stability.

[0015] A further improvement of this invention is that a flow control valve for controlling the oil output is provided at the horizontal pipe. By installing the flow control valve at the horizontal pipe, the oil output can be precisely controlled to meet the lubrication needs of the spindle housing under different operating conditions, thus improving the adaptability and accuracy of the lubrication system.

[0016] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0017] 1. This utility model, through the ingenious design of the frame ribs, has an internal oil storage chamber with corresponding oil inlets and outlets on both sides. Combined with the oil injection mechanism, oil delivery mechanism, and quick-connect oil injection and delivery pipes, the oil injection operation becomes easy and convenient. Unlike the traditional method, it does not require stopping the machine and removing the spindle, which greatly reduces refueling time and improves work efficiency.

[0018] 2. The filter unit in the oil delivery mechanism of this utility model can effectively intercept impurities in the oil, providing a reliable guarantee for the cleanliness of the lubricating oil, thereby reducing the risk of spindle wear and extending the service life of the equipment. At the same time, the flow control valve can precisely regulate the oil output and can be flexibly adjusted according to the actual working conditions of the spindle to ensure that the lubrication effect is always at its best.

[0019] 3. The design of this utility model reduces the losses caused by frequent shutdowns, disassembly of equipment for refueling and maintenance, which not only reduces equipment maintenance costs but also reduces production interruptions caused by equipment failures, further improving production efficiency and providing strong support for textile enterprises to achieve efficient and stable production.

[0028] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0029] Please refer to the attached document. Figure 1 The following is a description of a specific embodiment: The lubrication device for the main shaft seat of a spinning frame according to this utility model includes a frame rib 1. An oil storage chamber is provided inside the frame rib 1. An oil inlet communicating with the oil storage chamber is provided on the side of the frame rib 1 away from the frame, and an oil outlet communicating with the oil storage chamber is provided on the side of the frame rib 1 closer to the frame. An oil injection mechanism is connected to the frame rib 1 through the oil inlet. The oil injection mechanism is connected to an oil injection pipe through a quick connector, and the oil injection pipe is connected to an external oil source through a quick connector. An oil delivery mechanism 4 is connected to the frame rib 1 through the oil outlet. The oil delivery mechanism 4 is connected to an oil delivery pipe 6 through a quick connector, and the oil delivery pipe 6 is connected to the main shaft seat through a quick connector.

[0030] The frame rib 1 has an internal oil storage chamber with an oil inlet and an oil outlet on both sides. The oil inlet is connected to an external oil source via an oil injection mechanism, quick connector, and oil injection pipe. During oil injection, the oil flows into the oil storage chamber through this channel. The oil outlet is connected to the main shaft seat via an oil delivery mechanism 4, quick connector, and oil delivery pipe 6, delivering the oil from the oil storage chamber to the main shaft seat for lubrication. This design makes the lubrication operation of the spinning frame main shaft seat more convenient and efficient, avoiding the cumbersome process of stopping the machine to remove the spindle for oiling in the traditional way. It effectively saves lubrication time, improves production efficiency, and reduces equipment wear caused by frequent start-ups, shutdowns, and maintenance.

[0031] Among them, refer to the appendix Figure 2The oil injection mechanism includes a support pipe 2 connected to the oil inlet. The top inner part of the support pipe 2 is a threaded section 201, and a quick-connect pipe 3 is screwed onto the support pipe 2 through the threaded section 201. The bottom inner part of the support pipe 2 is an oil delivery section 202. The threaded section 201 and the oil delivery section 202 are connected vertically, and the diameter of the threaded section 201 is smaller than that of the oil delivery section 202, so that the threaded section 201 and the oil delivery section 202 form a stepped structure. A sealing component is provided inside the oil delivery section 202. The sealing component is used for the oil injection mechanism. When the quick-connect pipe 3 is fully connected to the threaded section 201, the bottom end of the quick-connect pipe 3 can trigger the sealing component, so that the oil injection mechanism is in the open state.

[0032] Among them, reference Figure 2 and 3 The sealing assembly includes a sealing plate 7, the diameter of which is larger than that of the threaded section 201 and smaller than that of the oil delivery section 202. A sealing spring 8 is connected to the bottom side of the sealing plate 7. The sealing spring 8 is connected to a support frame 203, which is fixed to the inner bottom of the oil delivery section 202. The sealing spring 8 enables the sealing plate 7 to always seal the bottom side of the threaded section 201, thereby keeping the oil injection mechanism in a closed state.

[0033] Inside the support pipe 2 of the oil injection mechanism, the threaded section 201 and the oil delivery section 202 are vertically connected and form a stepped structure. Under normal conditions, the sealing plate 7 is supported by the sealing spring 8, ensuring a tight seal between the sealing plate 7 and the bottom of the threaded section 201 to prevent oil leakage. When the quick-connect pipe 3 is fully inserted into the threaded section 201, its bottom end presses against the sealing plate 7, overcoming the elasticity of the sealing spring 8 and triggering the sealing assembly to open the oil injection channel, allowing oil to flow smoothly from the threaded section 201 into the oil delivery section 202. This ingenious design not only effectively prevents oil leakage in non-oil injection states, ensuring a clean working environment, but also precisely controls the start of oil injection, improving the safety and reliability of the oil injection operation.

[0034] Furthermore, the sealing assembly mainly consists of a sealing plate 7, a sealing spring 8, and a support frame 203. The sealing spring 8 connects the sealing plate 7 and the support frame 203 fixed to the bottom of the oil delivery section 202. Under the elastic force of the sealing spring 8, the sealing plate 7 always maintains a seal on the bottom side of the threaded section 201, ensuring that the oil injection mechanism is in a closed state when no oil injection operation is performed. This simple yet efficient sealing design greatly enhances the sealing performance of the oil injection mechanism, effectively avoids the risk of oil leakage, and reduces resource waste and equipment failure caused by oil leakage.

[0035] Among them, refer to the appendix Figure 5The oil delivery mechanism 4 includes a vertical pipe 401 and a horizontal pipe 402. One side of the vertical pipe 401 is connected to the horizontal pipe 402, and the vertical pipe 401 and the horizontal pipe 402 communicate with each other. The top of the vertical pipe 401 is connected to the oil outlet, and the horizontal pipe 402 is connected to the oil delivery pipe 6 through a quick connector.

[0036] The oil delivery mechanism 4 consists of a vertical pipe 401 and a horizontal pipe 402. The top of the vertical pipe 401 is connected to the oil outlet of the frame rib 1 to receive the oil flowing out of the oil storage chamber. One side of the vertical pipe 401 is connected to and communicates with the horizontal pipe 402. The horizontal pipe 402 is connected to the oil delivery pipe 6 via a quick connector to deliver the oil to the spindle seat. This structure provides a reasonable and smooth channel for the delivery of oil from the oil storage chamber to the spindle seat, ensuring the stable operation of the lubrication system and ensuring that the oil can smoothly reach the spindle seat, providing reliable lubrication support for the normal operation of the equipment.

[0037] Among them, refer to the appendix Figure 5 and 6 A filter unit is installed inside the vertical tube 401, and a sealing cap 403 is screwed to the bottom side of the vertical tube 401.

[0038] A filter unit is installed inside the vertical pipe 401 of the oil supply mechanism 4, and a sealing cap 403 is screwed to the bottom of the vertical pipe 401. When oil passes through the vertical pipe 401, the filter unit filters the oil, intercepting impurities and preventing them from entering the spindle seat with the oil. The sealing cap 403 seals the bottom of the vertical pipe 401, facilitating the installation and maintenance of the filter unit. The filter unit effectively protects the spindle seat, reduces wear caused by impurities, extends the service life of the equipment, and lowers maintenance costs.

[0039] Among them, refer to the appendix Figure 5 The filter unit includes an annular limiting plate 9 and a filter bag 11. The annular limiting plate 9 is located at the inner top of the vertical tube 401. An annular support plate 10 corresponding to the annular limiting plate 9 is provided at the opening of the filter bag 11. A helical spring 12 is sleeved on the outside of the filter bag 11. The helical spring 12 can make the annular support plate 10 press against the annular limiting plate 9.

[0040] The filtration unit consists of an annular limiting plate 9, an annular support plate 10, a filter bag 11, and a helical spring 12. The annular limiting plate 9 is located at the top inside the vertical pipe 401, and the annular support plate 10 is located at the opening of the filter bag 11, corresponding to and cooperating with the annular limiting plate 9. The helical spring 12 is fitted onto the outside of the filter bag 11, and its elasticity ensures that the annular support plate 10 always presses against the annular limiting plate 9, thus keeping the filter bag 11 taut. When the oil passes through the vertical pipe 401, the filter bag 11 filters the oil, intercepting impurities. This structural design is reasonable; the helical spring 12 ensures the stability of the filtration structure, improves the filtration effect, ensures the cleanliness of the oil entering the spindle seat, and provides a strong guarantee for the stable operation of the equipment.

[0041] In one embodiment, refer to the appendix Figure 2 The top of the oil conveying section 202 is provided with a sealing groove 204 corresponding to the sealing plate 7, and the sealing plate 7 is placed inside the sealing groove 204; the threaded section 201, the sealing groove 204 and the oil conveying section 202 are connected vertically to form a multi-stage stepped structure.

[0042] The top of the oil delivery section 202 is provided with a sealing groove 204 corresponding to the sealing plate 7. The threaded section 201, the sealing groove 204, and the oil delivery section 202 are sequentially connected to form a multi-stage stepped structure. The sealing plate 7 is placed inside the sealing groove 204. When the oil injection mechanism is closed, the sealing plate 7 not only fits tightly against the bottom side of the threaded section 201 but also cooperates with the sealing groove 204 to form a double seal. This structure further improves the sealing effect, ensuring that oil does not leak during the oil injection process, while improving the stability of the oil injection system, reducing the number of maintenance operations, and lowering maintenance costs.

[0043] In one embodiment, refer to the appendix Figure 4 The top of the quick-connect pipe 3 is connected to an external oil source via a quick connector, the bottom of the quick-connect pipe 3 is screwed to the threaded section 201, and the bottom outer wall of the quick-connect pipe 3 is provided with several auxiliary oil ports 301.

[0044] The top of the quick-connect pipe 3 is connected to an external oil source via a quick coupling, and the bottom is screwed to the threaded section 201 of the support pipe 2. Several auxiliary oil ports 301 are provided on its bottom outer wall. During oil injection, in addition to the central channel of the quick-connect pipe 3, the auxiliary oil ports 301 can also serve as the flow path for the oil. This increases the number of channels for oil to enter the oil storage chamber, allowing the oil to flow in more quickly and smoothly, effectively improving the oil injection efficiency, ensuring that the spindle seat receives sufficient lubricating oil in a timely manner, and guaranteeing the normal operation of the equipment.

[0045] In one embodiment, refer to the appendix Figure 4The quick-connect pipe 3 is provided with a sealing pressure plate 302 on the outside that can squeeze the top side of the support pipe 2. When the sealing pressure plate 302 squeezes the top side of the support pipe 2, the bottom end of the quick-connect pipe 3 squeezes the sealing plate 7 downward so that the sealing plate 7 can move downward out of the sealing groove 204.

[0046] During installation and operation, when the top side of the support tube 2 is squeezed, the sealing pressure plate 302 on the outer side of the quick-connect pipe 3 pushes the quick-connect pipe 3 downward, causing the bottom end of the quick-connect pipe 3 to press down on the sealing pressure plate 302. After being squeezed, the sealing pressure plate 302 overcomes the elastic force of the sealing spring 8 and moves downward out of the sealing groove 204, opening the oil injection channel. This design allows operators to precisely control the opening and closing of the oil injection mechanism with a simple squeezing action, making operation simple and highly accurate, improving the controllability of the oil injection operation, and facilitating flexible oil injection operations in different working scenarios.

[0047] In one embodiment, refer to the appendix Figure 1 A flow control valve 5 for controlling the oil output is installed at the horizontal pipe 402.

[0048] A flow control valve 5 is installed at the horizontal pipe 402 of the oil delivery mechanism 4. By adjusting the flow control valve 5, the outflow of oil in the horizontal pipe 402 can be precisely controlled. According to the lubrication requirements of the spinning machine spindle bearing under different working conditions, the operator can flexibly adjust the oil output to achieve precise lubrication. This design improves the adaptability and accuracy of the lubrication system, avoiding waste caused by excessive oil output and preventing poor lubrication caused by insufficient oil output, ensuring that the equipment achieves optimal lubrication under various working conditions.

[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
