Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a protective device for the tail shaft of a spinning machine. Background Technology

[0002] The spinning frame is the main machine for spinning yarn. It is a spinning machine that takes semi-finished roving or sliver, drafts, twists, and winds it into fine yarn bobbins during the spinning process. The tail spindle of the spinning frame is one of the main components for twisting and winding on the spinning frame. It is a slender rotating shaft supported at two points and connected to the motor.

[0003] The prior art, disclosed in CN218089948U, discloses a protective device for the tail shaft of a spinning machine, including a steel belt. A main shaft is arranged above the steel belt, and a wall plate is arranged behind the main shaft. The wall plate is connected to the main shaft through an oil tank. An opening and closing mechanism is arranged inside the oil tank and above the main shaft. The opening and closing mechanism includes a partition, a sealing gasket, a connecting block, a rack, a gear, and a knob. The partition is arranged inside the oil tank, and a sealing gasket is arranged at the center of the partition. A connecting block is arranged at the bottom of the sealing gasket, and a rack is arranged on the front of the connecting block. The rack is connected to the knob through the gear.

[0004] In use, rotating the knob drives the gears to rotate synchronously. As the gears rotate, they move the rack and connecting block up and down, adjusting the height of the sealing gasket. When the sealing gasket is raised, the baffle opens, allowing a suitable amount of oil from the oil tank to flow down and lubricate and protect the main shaft. However, this method cannot precisely add lubricating oil. Adding too little oil will result in insufficient lubrication, while adding too much oil will increase operating resistance, thus having certain limitations. Therefore, a tail shaft protection device for spinning locomotives needs to be designed to solve the above problems.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0032] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a protective device for the tail shaft of a spinning machine, comprising:

[0034] Wall panel 1, with oil tank 2 fixedly installed on wall panel 1, and the tail spindle 3 of the spinning machine connected to wall panel 1 through oil tank 2. A skeleton oil seal is installed at the connection between the tail spindle 3 of the spinning machine and oil tank 2. A metering addition mechanism is installed on oil tank 2. It should be noted that this makes it convenient to add lubricating oil in a metered manner, avoiding the situation of adding too much or too little lubricating oil, and fully protecting the tail spindle 3 of the spinning machine.

[0035] The quantitative addition mechanism includes an oil pipe 4, a top box 5, a storage pipe 7, a discharge pipe 8, a piston part 14, a threaded cylinder 15, a lead screw 16, a control indicator 17, and an indicator block 18.

[0036] Oil pipe 4 is fixedly installed between oil storage tank 2 and top tank 5. Discharge pipe 8 is fixedly installed on storage pipe 7. Piston part 2 14 is slidably sealed inside storage pipe 7. Threaded cylinder 15 is fixedly connected to piston part 2 14. Lead screw 16 is rotatably installed on top tank 5. Lead screw 16 is threadedly connected to threaded cylinder 15. Control indicator 17 is fixedly connected to lead screw 16. Indicator block 18 is fixedly installed on top tank 5.

[0037] With the above structure, the distance that piston part 2 14 moves when the lead screw 16 rotates once is preset. Based on the amount of lubricating oil that needs to be added to the tail main shaft 3 of the spinning machine within a certain period of time, two time intervals are determined, and the number of rotations of the lead screw 16 is determined. After the set time is reached, the control indicator 17 is rotated a specific number of times. At this time, the distance that piston part 2 14 moves is constant, so the amount of lubricating oil discharged from the discharge pipe 8 is also constant. This control method facilitates the quantitative addition of lubricating oil, avoids the situation of adding too much or too little lubricating oil, and fully protects the tail main shaft 3 of the spinning machine.

[0038] Specifically, the quantitative addition mechanism also includes a piston component 9, a connecting component 10, a horizontal plate 11, a sleeve plate 12, and a spring 13. The piston component 9 is slidably and sealed inside the storage tube 7, the horizontal plate 11 is fixedly installed inside the storage tube 7, the bottom of the connecting component 10 is fixedly connected to the piston component 9, the connecting component 10 is slidably installed on the horizontal plate 11, the sleeve plate 12 is fixedly sleeved on the outside of the connecting component 10, and the spring 13 is fixedly installed between the sleeve plate 12 and the horizontal plate 11.

[0039] With the above structure, the bottom of piston component 9 is flush with the lower opening of the discharge pipe 8. Piston component 9 can play a certain blocking role, preventing excess lubricating oil from overflowing due to external vibration and other problems during equipment operation. When piston component 14 moves, the lubricating oil pushes piston component 9, causing piston component 9 to move upward a very small distance. Then the lubricating oil is discharged through the discharge pipe 8. If there is a small error, this error is within a controllable range.

[0040] Specifically, an adding tube 21 is fixedly installed on the storage tube 7, and a threaded cap 22 is threaded onto the adding tube 21. A top hole is opened on the top of the top box 5, and a counterweight box cover is fitted into the top hole. It should be noted that when lubricating oil needs to be added later, the counterweight box cover is removed, and then the threaded cap 22 is removed. The adding tube 21 is then filled with lubricating oil until the level of the lubricating oil is flush with the bottom of the piston component 9. After the threaded cap 22 is on, sealing tape can be wrapped around it to ensure the sealing of the connection. Moreover, the distance between the level of the lubricating oil and the inner wall of the top of the threaded cap 22 is extremely small. If there is a small error, it is within a controllable range.

[0041] Specifically, a support plate 6 is fixedly installed on the storage tube 7, and the bottom of the support plate 6 is fixedly connected to the top box 5. A slider 19 is fixedly installed on the outside of the threaded cylinder 15, and a block 20 is fixedly installed on the storage tube 7. The slider 19 is slidably installed on the block 20. It should be noted that this is to facilitate the stable lateral movement of the threaded cylinder 15.

[0042] Specifically, the discharge pipe 8 is located above the oil pipe 4, and the storage pipe 7 contains lubricating oil, which is convenient for adding lubricating oil.

[0043] Specifically, a limiting plate is fixedly installed on the top of the connector 10, and the bottom of the limiting plate is in contact with the horizontal plate 11. It should be noted that the connector 10 is subject to limiting treatment.

[0044] Working principle:

[0045] S1: When adding lubricating oil in a measured amount, the distance the piston 14 moves after one rotation of the lead screw 16 must be pre-set. Based on the actual amount of lubricating oil needed for the tail spindle 3 of the spinning machine within a certain period, two time intervals are determined, and the number of rotations of the lead screw 16 within that time period is calculated accordingly. When the set time is reached, the operator rotates the control indicator 17. Since the control indicator 17 is fixedly connected to the lead screw 16, the lead screw 16 rotates accordingly. Because the lead screw 16 is threadedly connected to the threaded cylinder 15, and the threaded cylinder 15... The outer slider 19 is horizontally slidably mounted on the block 20 of the storage tube 7, so that the threaded cylinder 15 can only move horizontally and stably when the screw 16 rotates, thereby driving the piston part 2 14 fixedly connected to it to slide in the storage tube 7. Since the distance the piston part 2 14 moves is determined according to the set number of rotations of the screw 16, the amount of lubricating oil discharged from the discharge pipe 8 is also fixed, thus realizing the quantitative addition of lubricating oil, effectively avoiding the situation of adding too much or too little lubricating oil, and fully protecting the tail main shaft 3 of the spinning machine.

[0046] S2: When piston part 2 14 moves downward to push the lubricating oil, the lubricating oil will push piston part 1 9. The bottom of piston part 1 9 is flush with the lower opening of the discharge pipe 8. Originally, it plays a blocking role to prevent excess lubricating oil from overflowing due to external vibration and other factors during equipment operation. When it is pushed by the lubricating oil, piston part 1 9 moves upward a very small distance under the drive of connecting part 10, so that the lubricating oil can be discharged smoothly through the discharge pipe 8. If there is a small error in this process, it is within the controllable range and does not affect the overall quantitative addition effect. The discharged lubricating oil flows into the oil storage tank 2 through the oil pipe 4, and then lubricates and protects the tail main shaft 3 of the spinning machine.

[0047] S3: When the lubricating oil in the storage tube 7 needs to be replenished, the operator first removes the counterweight box cover inside the top hole of the top box 5, then unscrews the threaded cap 22 on the adding tube 21. Subsequently, lubricating oil is injected into the storage tube 7 through the adding tube 21 until the lubricating oil level is flush with the bottom of the piston component 9. To ensure the sealing of the connection and prevent lubricating oil leakage, sealing tape can be wrapped after screwing on the threaded cap 22. At this time, the distance between the lubricating oil level and the inner wall of the top of the threaded cap 22 is extremely small. Even if there is a small error, it is within a controllable range, ensuring the stability of lubricating oil storage.
