Description

Technical Field

[0001] The present invention relates to the technical field of plastic weaving machinery, and particularly to a plastic circular loom. Background Art

[0002] In existing plastic circular looms, the warp wire lubrication device is usually arranged inside the door ring assembly (such as on the surface of the upper door ring or the lower door ring), and lubrication is achieved by a fixed oil felt adsorbing lubricating oil (see Patent CN114381843A). However, this solution has the following problems: Both the upper and lower door rings need to be drilled, which makes the process flow cumbersome and increases costs. Setting an oil supply pipe on the door ring will also occupy the passage of the warp wires. When the warp wires are pulled, they will rub against the oil pipe, and both the warp wires and the oil pipe will be worn.

[0003] The static oil felt depends on the passive scraping of the warp wires to obtain oil, which easily causes local dryness or over - supply of the oil felt, affecting the lubrication effect of the warp wires. Summary of the Invention

[0004] The purpose of the present invention is to overcome the drawbacks and deficiencies existing in the prior art, and to provide a plastic circular loom, which forms a continuous oil film through the rolling cooperation of an oil roller and a semi - enclosed lubricant carrier, and uses segmented lubrication points to improve the lubrication effect.

[0006] As a preferred technical solution of the present invention, when the warp wires are conveyed from the outer side of the door ring assembly to the center, they sequentially contact the surface of the oil roller to form a first lubrication point, and the exposed part at the opening of the lubricant carrier to form a second lubrication point.

[0007] As a preferred technical solution of the present invention, the lubricant carrier is an oil felt, and the fuel supply assembly includes an oil storage tank and an oil supply pipe. One end of the oil supply pipe is connected to the oil storage tank, and the other end extends to the oil felt to supply oil to it.

[0008] As a preferred technical solution of the present invention, the lubricating medium carrier is a solid oil storage box with a permeable membrane and the permeable membrane is arranged facing the oil roller, and the oil supply assembly includes an oil reservoir and an oil supply pipe, one end of the oil supply pipe is connected to the oil reservoir and the other end extends into the solid oil storage box.

[0009] As a preferred technical solution of the present invention, the oil reservoir is higher than the lubricating medium carrier and allows the lubricating oil to automatically flow to the oil felt through the oil supply pipe; or, the oil supply pipe is provided with an oil pump that pumps the lubricating oil to the lubricating medium carrier.

[0010] As a preferred technical solution of the present invention, a gap is left between the upper inner wall of the lubricating medium carrier and the outer wall of the oil roller to form an oil guide port, and one end of the oil supply pipe extends into the oil guide port.

[0011] As a preferred technical solution of the present invention, it also includes an oil storage tank located below the lubricating medium carrier, and the oil storage tank is used to collect lubricating oil dripping from the lubricating medium carrier and / or the oil roller.

[0012] As a preferred technical solution of the present invention, it also includes a fixed frame connected to the outside of the door ring assembly, the oil roller is rotatably installed on the fixed frame, the lubricating medium carrier is connected to the fixed frame and is located on the side of the oil roller facing away from the door ring assembly, the opening of the lubricating medium carrier is arranged toward the side of the door ring assembly, and the warp wire sequentially contacts the surface of one side of the oil roller close to the door ring assembly to form a first lubrication point, and the upper end part of the opening of the lubricating medium carrier forms a second lubrication point.

[0013] As a preferred technical solution of the present invention, a wire guide frame is fixed on the outside of the door ring assembly, and the fixed frame is installed on the wire guide frame. After the warp wire passes through the first lubrication point and the second lubrication point, it is turned and pulled into the door ring assembly through the wire guide frame.

The warp threads sequentially contact the surface of the oil roller and the exposed part at the opening of the lubricant medium carrier. The oil roller rotates (passively rotates when the warp threads are pulled or actively rotates driven by a motor) and rolls in cooperation with the lubricant medium carrier to form a dynamic oil film. The rotation of the oil roller can evenly spread the lubricating oil, avoiding uneven oil quantity on the surface of the oil roller. The lubricant medium carrier replenishes oil to the warp threads that first pass through the oil roller for the second time, enabling the warp threads to carry sufficient lubricating oil and ensuring the lubrication effect between the subsequent warp threads and the outer guide rod of the shuttle, significantly improving the lubrication uniformity and reliability.

[0016] There is no need to drill holes in the door ring assembly, which simplifies the process flow and reduces the manufacturing cost. The oil supply pipe directly corresponds to the oil roller and the lubricant medium carrier, avoiding the oil pipe occupying the internal space of the door ring assembly and causing wear to the warp threads.

Detailed Description of the Invention

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "installed", "equipped with", "connected", etc. shall be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0021] Such as Figures 1-5A plastic circular loom shown includes a main machine 1, the main machine 1 includes a door ring assembly 2 and a shuttle 3, the door ring assembly 2 has a runway for the circumferential movement of the shuttle 3, the door ring assembly 2 includes an upper door ring and a lower door ring, an end wire lubrication device 4 is provided outside the door ring assembly 2, and the end wire lubrication device 4 includes: an oil roller 5 rotatably (both ends of the oil roller 5 are fitted with bearings) installed outside the door ring assembly 2; a lubricating medium carrier 6 semi-covering (the "semi-covering" does not simply mean "covering half", and generally means that an object or component covers a partial area in packaging or design, rather than being completely wrapped) the outside of the oil roller 5 and is fixed relative to the door ring assembly 2, an opening 7 is provided on one side of the lubricating medium carrier 6 to expose at least part of the outer peripheral surface of the oil roller 5 to the outside of the lubricating medium carrier 6 for lubricating the end wire 23; an oil supply assembly 8 for supplying lubricating oil to the lubricating medium carrier 6 and / or the oil roller 5; when the oil roller 5 rotates, it rolls with the lubricating medium carrier 6 to form a continuous oil film on the surface of the oil roller 5. When the end wire 23 is conveyed from the outside of the door ring assembly 2 to the center, it sequentially contacts the surface of the oil roller 5 to form a first lubrication point 9, and the exposed part at the opening 7 of the lubricating medium carrier 6 forms a second lubrication point 10 (the end of the lubricating medium carrier 6 is preferably provided with an arc surface to prevent the end wire 23 from being worn, or it can also be set as a guiding inclined surface). In this embodiment, the lubricating medium carrier 6 refers to any structure that can adsorb and hold lubricating oil and can transfer lubricating oil through contact when the end wire 23 passes through. The main idea of this application lies in the specific structure of the end wire lubrication device 4. Regarding other components of the circular loom, they are prior art and will not be specifically described in this application. The first lubrication point 9 and the second lubrication point 10 in this embodiment are not limited to contact points and can also be understood as the contacting parts; during the process of the end wire on the end wire frame being pulled towards the inside of the door ring assembly 2, it may only contact the first lubrication point 9 or the second lubrication point 10, or contact both the first lubrication point 9 and the second lubrication point 10. Only the lubricating medium carrier 6 with different lengths needs to be replaced. If the upper exposed part at the opening of the lubricating medium carrier 6 is closer to the door ring assembly 2 than the oil roller 5, the end wire only contacts the second lubrication point 10. If it is further back, it only contacts the first lubrication point 9. If the position is appropriate, the end wire contacts both the first lubrication point 9 and the second lubrication point 10. Whether to adjust depends on the actual working conditions. Of course, the lower part of the lubricating medium carrier 6 can also be adjusted; if the lower part at the opening of the lubricating medium carrier 6 is closer to the door ring assembly 2 than the oil roller 5, a third lubrication point can be formed.

[0022] The lubricating medium carrier 6 is a felt. The oil supply assembly 8 includes an oil storage device 11 and an oil supply pipe 12. One end of the oil supply pipe 12 is connected to the oil storage device 11, and the other end extends to the felt to supply oil to it. In the prior art, the circular knitting machine felt is fixed to the inner wall of the door ring assembly 2, and the warp wire 23 contacts the lubrication once. The lubrication amount is limited by the oil absorption saturation of the felt. During high-speed knitting, intermittent oil supply is likely to occur. It depends on the passive scraping of the felt by the warp wire 23 to obtain oil. Without moving parts, it is easy to cause local dryness and caking of the felt. In the present application, the oil roller 5 rotates to promote the uniform diffusion of the lubricating oil and avoid caking of the felt. The felt in this embodiment can also be made of materials with oil absorption characteristics such as sponge and porous ceramics.

[0023] The lubricating medium carrier 6 is a solid oil storage box with a permeable membrane, and the permeable membrane faces the oil roller 5. The oil supply assembly 8 includes an oil storage device 11 and an oil supply pipe 12. One end of the oil supply pipe 12 is connected to the oil storage device 11, and the other end extends into the solid oil storage box. In this embodiment, the solid oil storage box can be made of a metal shell, and any material with a permeable function can be used for the permeable membrane. Here, one example is listed without limiting its structure. The solid oil storage box is an aluminum alloy shell, filled with porous ceramics inside, and the permeable membrane is a polytetrafluoroethylene microporous membrane.

[0024] The oil storage device 11 is higher than the lubricating medium carrier 6, and the lubricating oil automatically flows onto the felt through the oil supply pipe 12; or, a oil pump for pumping the lubricating oil to the lubricating medium carrier 6 is provided on the oil supply pipe 12.

[0025] A gap is left between the upper inner wall of the lubricating medium carrier 6 and the outer wall of the oil roller 5 to form an oil guiding port 13. One end of the oil supply pipe 12 extends into the oil guiding port 13. In this embodiment, the part of the oil supply pipe 12 located in the oil guiding port 13 is equidistantly distributed with oil outlet holes along the axial direction.

[0026] It further includes an oil storage tank 14 located below the lubricating medium carrier 6. The oil storage tank 14 can be installed on a fixed frame 15 or a wire guiding frame 16. The oil storage tank 14 is used to collect the lubricating oil dripping from the lubricating medium carrier 6 and / or the oil roller 5. In this embodiment, the lubricating medium carrier 6 and the oil roller 5 are located above the oil storage tank 14 and neither of them contacts the oil storage tank 14. Or, the oil roller 5 and the lubricating medium carrier 6 are partially placed in an oil sump, and lubricating oil can be placed in the oil storage tank 14 in advance to directly contact the oil roller 5 and the lubricating medium carrier 6. The purpose of installing the oil storage tank 14 is to realize the recycling of waste oil.

[0027] It further includes a fixed frame 15 connected to the outside of the door ring assembly 2. The oil roller 5 is rotatably installed on the fixed frame 15. The lubricating medium carrier 6 is connected to the fixed frame 15 and is located on the side of the oil roller 5 facing away from the door ring assembly 2. The opening 7 of the lubricating medium carrier 6 is arranged facing the side of the door ring assembly 2. The warp wire 23 sequentially contacts the side surface of the oil roller 5 close to the door ring assembly 2 to form a first lubrication point 9, and the upper end part of the opening 7 of the lubricating medium carrier 6 to form a second lubrication point 10.

[0028] A wire guide frame 16 is fixedly installed on the outer side of the door ring assembly 2. A fixing frame 15 is mounted on the wire guide frame 16. The warp wire 23 passes through the first lubrication point 9 and the second lubrication point 10, and then is turned and pulled into the door ring assembly 2 through the wire guide frame 16.

[0029] The wire guide frame 16 includes a wire guide rod 17 having a commutation hole 18, and the wire guide rod 17 is arranged on the side of the fixing frame 15 facing away from the door ring assembly 2. The warp wire 23 passes through the commutation hole 18 and is pulled towards the weaving area of the door ring assembly 2. The warp wire 23 passes through the heddle eyes of the inner heddles and outer heddles and contacts and lubricates the outer guide rods 22 at the upper and lower ends of the shuttle 3 respectively. The path of the warp wire 23 during pulling depends on the specific working conditions and is not specifically limited. After the warp wire 23 passes through the first lubrication point 9, lubricating oil is evenly attached to its lower surface; subsequently, the warp wire 23 passes through the wire guide rod 17 and the heddle eyes of the heddles in sequence. During this process, due to the path guidance of the wire guide rod 17 and the heddles, the lower surface of the warp wire 23 may face upwards due to the change in the winding direction, so as to contact and lubricate the outer guide rod 22 below the shuttle 3; the lower surface direction of a part of the warp wire 23 does not change, so its lower surface contacts and completes lubrication with the outer guide rod 22 above the shuttle 3. The warp wire 23 passing through the wire guide rod 17 will be pulled towards the outer guide rod 22 above the shuttle or the outer guide rod 22 below the warp wire. In this embodiment, at least one set of warp wire lubrication devices 4 is arranged along the circumferential direction, and multiple sets can also be arranged at intervals along the circumferential direction. The oil roller 5 is installed on the support rod 19 through the fixing frame 15. The support rod 19 is actually a circular ring (only part of it is shown in the drawing). The fixing frame 15 changes with the radian of the support rod 19, and the angle of the fixing frame 15 is adjusted accordingly. The angles of the oil rollers 5 at different positions will also change. The axis of the oil roller 5 is perpendicular to the center line of the door ring assembly, or the oil roller 5 is slightly inclined at a certain angle, which is specifically set according to the actual situation, and try to ensure that each warp can contact the oil roller.

[0030] The wire guide frame 16 includes a support rod 19 located below the oil roller 5 and a wire guide plate 20 located below the support rod 19. The fixing frame 15 is mounted on the support rod 19. The wire guide plate 20 is provided with a plurality of wire guide holes 21 along the circumferential direction.

[0031] The preferred method of the present application is double-point lubrication: its working principle: the present application arranges an oil roller 5 on the outside of the gate ring assembly 2 to cooperate with a semi-covered lubricating medium carrier 6 to form a double lubrication point when the warp 23 passes through, and the warp 23 contacts the surface of the oil roller 5 and the exposed part at the opening 7 of the lubricating medium carrier 6 in turn. The oil roller 5 rotates (when the warp 23 is pulled, the friction force forms an angle with the oil roller 5 to drive the oil roller 5 to rotate passively or the motor drives the oil roller 5 to rotate actively) and rolls with the lubricating medium carrier 6 to form a dynamic oil film. The rotation of the oil roller 5 can evenly spread the lubricating oil to avoid uneven oil on the surface of the oil roller 5. The lubricating medium carrier 6 is used to replenish the warp 23 that passes through the oil roller 5 for the first time, so that the warp 23 carries a sufficient amount of lubricating oil, ensuring the lubrication effect between the subsequent warp 23 and the outer guide rod 22 of the shuttle 3, and significantly improving the lubrication uniformity and reliability.

[0032] The basic principles, main features and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which shall fall within the scope of the present invention to be protected.
