Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of slotted winding equipment, and in particular to a spiral grooved cylinder for an automatic winding machine for antibacterial silver fiber. Background Technology
[0002] Antibacterial silver fiber is a functional fiber made by combining silver ions with fibers through a special technology. It usually uses silver ion physical slow-release technology to inject metallic silver into the fiber like a bullet and combine it with the fiber. Then, through a special process, the physically processed silver fiber is blended with nylon or polyester fiber to form yarn. After the antibacterial silver fiber is produced, it is usually further processed by an automatic winding machine. The automatic winding machine requires grooved drums to guide the yarn. The grooved drums are consumable parts of the winding machine. The high-speed rotating grooved drums are in contact with the support on the winding machine for a long time during yarn guidance, which makes the ends of the grooved drums very easy to wear, reducing the service life of the grooved drums. If they are not replaced in time, it will affect the normal operation of the grooved drums and further increase the production cost. Utility Model Content
[0003] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose an antibacterial silver fiber automatic winding machine spiral groove cylinder.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An antibacterial silver fiber automatic winding machine spiral groove cylinder includes an outer cylinder body. A left sealing ring and a right sealing ring are fixed to the left and right ends of the inner part of the outer cylinder body, respectively. A connecting rod is laterally fixed to the middle left side of the left sealing ring and the middle right side of the right sealing ring. A limit post is fixed inside the connecting rod. A sealing plate and a return spring are nested outside the limit post. A guide rod is laterally fixed between the left and right sealing rings. An air bag is embedded in the middle of the outer cylinder body. An air inlet and outlet pipe is fixedly connected to the lower left side of the air bag. A left pressure plate and a right pressure plate are nested at the left and right ends of the outer wall of the guide rod, respectively.
[0006] Preferably, the connecting rod has an outer groove inside its internal opening, and the outer groove has an oil drain groove that communicates with the inside of the limiting post. Both the left and right sealing rings have oil injection holes on their upper surfaces.
[0007] Preferably, the cross-sectional area of the oil drain groove is smaller than the cross-sectional area of the outer groove, and the cross-sectional area of the sealing plate is larger than the cross-sectional area of the oil drain groove but smaller than the cross-sectional area of the outer groove.
[0008] Preferably, the sealing plate is tightly attached to and covers the outside of the oil drain groove, and the sealing plate slides horizontally on the outer wall of the limiting post.
[0009] Preferably, the left pressure plate and the right pressure plate are symmetrically arranged around the longitudinal central axis of the outer cylinder, and the right side of the left pressure plate and the left side of the right pressure plate are respectively close to the left and right ends of the airbag.
[0010] Preferably, the right side of the left pressure plate and the outer wall of the right pressure plate are in close contact with the inner wall of the outer cylinder, and the left and right pressure plates slide left and right along the guide rod in the horizontal direction within the outer cylinder.
[0011] During the rotation of the trough, due to the centrifugal force, the sealing plate moves along the limiting post to the end away from the center of the limiting connecting rod. At this time, the sealing plate on the limiting post no longer seals the oil drain groove inside the connecting rod, allowing the lubricating oil stored on both sides inside the trough to flow out through the oil drain groove from the connecting rod, automatically lubricating the outer surface of the connecting rod. This prevents the connecting rods at both ends of the trough from overheating and being damaged due to friction contact with the support during the rotation of the trough for a long time, further improving the service life of the device.

[0016] Legend:
[0017] Outer cylinder 1, left sealing ring 2, right sealing ring 3, connecting rod 4, limiting post 401, sealing plate 402, return spring 403, guide rod 5, airbag 501, inlet and outlet pipe 502, left pressure plate 503, right pressure plate 504. Detailed Implementation
[0018] Example 1, referring to Figure 1-4An antibacterial silver fiber automatic winding machine spiral groove cylinder includes an outer cylinder 1. A left sealing ring 2 and a right sealing ring 3 are fixed to the left and right ends of the outer cylinder 1, respectively. A connecting rod 4 is horizontally fixed to the middle left side of the left sealing ring 2 and the middle right side of the right sealing ring 3. A limiting post 401 is fixed inside the connecting rod 4. A sealing plate 402 and a return spring 403 are nested on the outside of the limiting post 401. A guide rod 5 is horizontally fixed between the left sealing ring 2 and the right sealing ring 3. An air bag 501 is embedded in the middle of the outer cylinder 1. An air inlet and outlet pipe 502 is fixedly connected to the lower left side of the air bag 501. A left pressure plate 503 and a right pressure plate 504 are nested on the left and right ends of the outer wall of the guide rod 5, respectively.
[0019] The connecting rod 4 has an outer groove inside its internal opening, and an oil drain groove that communicates with the inside of the limiting post 401 is provided inside the outer groove. Both the left sealing ring 2 and the right sealing ring 3 have oil injection holes on their upper parts.
[0020] The cross-sectional area of the oil drain groove is smaller than that of the outer groove, and the cross-sectional area of the sealing plate 402 is larger than that of the oil drain groove but smaller than that of the outer groove.
[0021] When the sealing plate 402 moves outward and no longer covers the oil drain groove, the lubricant will pass through the oil drain groove into the outer groove, and then be discharged from the outside of the outer groove to lubricate the outer surface of the connecting rod 4.
[0022] The sealing plate 402 is tightly attached to and covers the outside of the oil drain groove, and the sealing plate 402 slides horizontally on the outer wall of the limiting post 401.
[0023] During the rotation of the trough, due to the centrifugal force, the sealing plate 402 moves along the limiting post 401 to the end away from the center of the limiting connecting rod 4, compressing the return spring 403. At this time, the sealing plate 402 on the limiting post 401 no longer seals the oil drain groove inside the connecting rod 4, allowing the lubricating oil stored on the left and right sides inside the trough to flow out through the oil drain groove from the connecting rod 4, automatically lubricating the outer surface of the connecting rod 4. This prevents the connecting rod 4 at the left and right ends from overheating and being damaged due to frictional contact with the support during the rotation of the trough for a long time, further improving the service life of the device.
[0024] When the groove cylinder stops rotating, the return spring 403 pulls the sealing plate 402 back to its original position to cover the outside of the oil drain groove and seal the oil drain groove, so as to prevent the lubricating oil from flowing out through the oil drain groove when the groove cylinder stops rotating, thus avoiding the waste of lubricating oil.
[0025] Example 2 differs from Example 1 in that, in this example, the left pressure plate 503 and the right pressure plate 504 are symmetrically arranged around the longitudinal central axis of the outer cylinder 1, and the right side of the left pressure plate 503 and the left side of the right pressure plate 504 are respectively in close contact with the left and right ends of the airbag 501.
[0026] After injecting an appropriate amount of lubricating oil into the oil injection holes above the left sealing ring 2 and the right sealing ring 3, the lubricating oil will be stored between the left sealing ring 2 and the left pressure plate 503, and between the right sealing ring 3 and the right pressure plate 504.
[0027] The right side of the left pressure plate 503 and the outer wall of the right pressure plate 504 are in close contact with the inner wall of the outer cylinder 1. The left pressure plate 503 and the right pressure plate 504 slide left and right in the outer cylinder 1 along the guide rod 5 in the horizontal direction.
[0028] When there is less lubricating oil at the left and right ends inside the outer cylinder 1, an appropriate amount of gas is injected into the intake and exhaust pipes 502, causing the airbag 501 to expand to the left and right ends, pushing the left pressure plate 503 to the left and the right pressure plate 504 to the right, so that the left pressure plate 503 and the right pressure plate 504 push the lubricating oil into the connecting rod 4 of the left sealing ring 2 and the right sealing ring 3, so that the subsequent lubricating oil can be discharged from the inside of the connecting rod 4;
[0029] The main function of the guide rod 5 is to limit the left and right movement of the left pressure plate 503 and the right pressure plate 504, so as to prevent them from being misaligned or offset during the left and right sliding process.
[0030] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
