DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] An embodiment of an oiling mechanism of a winding machine of the present invention is as follows Figures 1 to 7 As shown, the machine comprises a frame 100 , a winding device 200 , an oil tanker 300 and a yarn bobbin 400 .

[0029] The winding device 200 , the oil tanker 300 and the yarn bobbin 400 are all installed on the frame 100 . The winding device 200 reels the yarn 410 on the yarn bobbin 400 after the yarn 410 is oiled by the oil tanker 300 .

[0030] The oil tanker 300 includes a hub 310, an oil suction ring 320 and a lifting plate assembly 330; the hub 310 is hollow inside and is used to fill oil; the oil suction ring 320 is sleeved outside the hub 310 and is a flexible structure capable of absorbing oil, and is used to contact the yarn 410 and rotate when the yarn 410 moves, and drive the hub 310 to rotate synchronously. Specifically, the oil suction ring 320 is a sponge material. An oil outlet channel 311 connecting the inside and outside of the hub 310 is opened inside the hub 310, and the oil outlet channel 311 guides the oil inside the hub 310 to flow to the oil suction ring 320. The lifting plate assembly 330 is installed on the hub 310, and when the oil tanker 300 rotates, it guides the oil inside the hub 310 to be dispersed in the circumferential direction of the inner wall of the hub 310, assists the oil to flow out through the oil outlet channel 311, and makes the oil output positively correlated with the rotation speed of the oil tanker 300.

[0031] By arranging a tensioning wheel on the frame 100 to guide the moving path of the yarn 410, the oil absorption ring 320 of the oil tanker 300 can abut against the yarn 410. When the yarn 410 is wound up by the winding device 200 and moves, the oil tanker 300 can be driven to rotate by abutting against the oil absorption ring 320. The oil in the hub 310 flows in the hub 310 as the hub 310 rotates, and flows from the oil outlet channel 311 to the oil absorption ring 320, so that the oil absorption ring 320 is soaked in oil, and then the oil is applied to the yarn 410 when the yarn 410 passes by. The faster the yarn 410 moves, the faster the oil tanker 300 rotates, and the more oil on the oil absorption ring 320 is taken away by the yarn 410 per unit time. The shovel assembly 330 is arranged so that the oil output of the oil outlet channel 311 is positively correlated with the rotation speed of the oil tanker 300, so that the oil on the oil absorption ring 320 can be further supplemented when the rotation speed of the oil tanker 300 increases, thereby ensuring its coating effect on the yarn 410.

[0032] Furthermore, the oil flows from the hub 310 to the oil absorption ring 320 sleeved outside the hub 310, which can reduce the degree of oil leakage, thereby reducing the volatilization and oxidation of the oil, thereby saving the amount of oil on the basis of ensuring the coating effect on the yarn 410.

[0033] In this embodiment, the hub 310 is provided with a plurality of sliding grooves along its radial direction and penetrating inside and outside the hub 310, and there are a plurality of lifting plate assemblies 330, each of which is installed in a corresponding sliding groove. The lifting plate assembly 330 includes a counterweight plate 331, a scissor rod group, a connecting plate 333 and a lifting plate 334; the scissor rod group includes a first rod 332 and a second rod 336, the first rod 332 and the second rod 336 are cross-arranged and hinged to the same hinge shaft 335 at the intersection, and the hinge shaft 335 is fixed to the side wall of the sliding groove. One end of the first rod 332 and the second rod 336 is slidably connected to the counterweight plate 331, and the other end is slidably connected to the connecting plate 333, and the counterweight plate 331 is located on the side of the connecting plate 333 away from the center of the hub 310. The counterweight plate 331, the scissor rod group, and the connecting plate 333 are all parallel to the extension direction of the sliding groove. The lifting plate 334 is perpendicular to the connecting plate 333, is located inside the wheel hub 310, and is connected to the side of the connecting plate 333 close to the center of the wheel hub 310; the counterweight plate 331 moves in the direction away from the center of the wheel hub 310 under the centrifugal effect of the rotation of the wheel hub 310, and then the connecting plate 333 and the lifting plate 334 move in the direction close to the center of the wheel hub 310 under the transmission of the scissor-type rod group. Specifically, the faster the rotation speed of the wheel hub 310, the greater the distance that the counterweight plate 331 moves in the direction away from the center of the wheel hub 310 under the centrifugal effect, the greater the distance that the connecting plate 333 and the lifting plate 334 move in the direction close to the center of the wheel hub 310 under the transmission of the scissor-type rod group, the more oil the connecting plate 333 and the lifting plate 334 lift when rotating, and the greater the amount of oil flowing out through the oil outlet channel 311.

[0034] In this embodiment, the counterweight plate 331 is provided with a first connection groove perpendicular to the plane where the first rod 332 and the second rod 336 are located, and one end of the first rod 332 and the second rod 336 is slidably mounted in the first connection groove. The connecting plate 333 is provided with a second connection groove perpendicular to the plane where the first rod 332 and the second rod 336 are located, and the other end of the first rod 332 and the second rod 336 is slidably mounted in the second connection groove. A spring (not shown in the figure) is installed in the first connection groove and / or the second connection groove to push the ends of the first rod 332 and the second rod 336 away from each other. The spring pushes the ends of the first rod 332 and the second rod 336 away from each other, thereby pushing the counterweight plate 331 and the connecting plate 333 to approach each other, so that the counterweight plate 331 and the connecting plate 333 return to their initial positions when the wheel hub 310 stops rotating.

[0035] In this embodiment, a mounting groove for mounting the oil suction ring 320 is provided on the outer circumferential surface of the wheel hub 310. The mounting groove is coaxial with the wheel hub 310, and the cross section perpendicular to the circumferential direction of the wheel hub 310 is a trapezoid, and the short side of the trapezoid is located on the side of the long side close to the center of the wheel hub 310. The trapezoidal mounting groove is provided to reduce the movement of the oil suction ring 320 outside the wheel hub 310 and ensure the transmission effect.

[0036] In this embodiment, there are multiple oil outlet channels 311, and at least three of them form a group. Multiple groups of oil outlet channels 311 are arranged at intervals around the wheel hub 310 in the circumferential direction. The oil outlet channels 311 in the same group are connected to the inside of the wheel hub 310 and different side walls of the mounting groove. Multiple groups of oil outlet channels 311 and multiple lifting plate assemblies 330 are alternately distributed in the circumferential direction of the wheel hub 310. Specifically, the oil suction ring 320 can be fixedly connected to the oil outlet channel 311 opened on the outer circumferential surface of the wheel hub 310, and not fixedly connected to the sliding groove to ensure the connection effect between the oil suction ring 320 and the wheel hub 310. At the same time, the counterweight plate 331 can extend out of the sliding groove when moving away from the center of the wheel hub 310, pushing the oil suction ring 320 to deform, thereby increasing its contact area with the yarn 410, and ensuring the coating effect when the yarn 410 moves faster.

[0037] In this embodiment, an oil inlet 313 and an oil outlet 314 are respectively formed on two sides of the hub 310 .

[0038] In this embodiment, a filter screen 315 is installed inside the wheel hub 310 to filter the oil entering the oil outlet channel 311 .

[0039] In this embodiment, the winding device 200 includes a driving member 210, a driving wheel 220 and a winding wheel 230; the driving wheel 220 and the winding wheel 230 are both rotatably mounted on the frame 100, and the driving wheel 220 rotates under the drive of the driving member 210, and the winding wheel 230 is tangent to and abuts against the driving wheel 220, and rotates under the drive of the driving wheel 220; wherein the driving member 210 is a motor. A guide groove is provided on the driving wheel 220, and the guide groove guides the yarn 410 to reciprocate along the axis of the winding wheel 230 and then winds around the winding wheel 230.

[0040] When the oiling mechanism of the winding machine of the present invention is used, the oil is injected into the hub 310 from the oil inlet 313 and then the oil inlet 313 is blocked. After the yarn 410 is wound from the bobbin 400, it passes through the oil wheel 300 and the driving wheel 220 in sequence and is connected and wound on the winding wheel 230. Among them, a retractable tensioning wheel can be installed on the frame 100 to abut against the yarn 410, so that the yarn 410 is attached to the oil absorption ring 320 outside the hub 310. The driving wheel 220 rotates under the drive of the driving member 210, thereby driving the winding wheel 230 to rotate and the yarn 410 to move. While the yarn 410 moves, it drives the hub 310 to rotate by abutting against the oil absorption ring 320. When the hub 310 rotates, it drives the oil inside it to rotate, so that the oil flows from the oil outlet channel 311 to the oil absorption ring 320, and the oil absorption ring 320 is soaked in the oil and coated on the yarn 410.

[0041] When the wheel hub 310 rotates, the counterweight plate 331 moves away from the center of the wheel hub 310 under the centrifugal action, so that the connecting plate 333 and the lifting plate 334 move toward the center of the wheel hub 310 under the transmission of the scissor rod group. The faster the rotation speed of the wheel hub 310, the greater the distance that the counterweight plate 331 moves away from the center of the wheel hub 310 under the centrifugal action, the greater the distance that the connecting plate 333 and the lifting plate 334 move toward the center of the wheel hub 310 under the transmission of the scissor rod group, the more oil the connecting plate 333 and the lifting plate 334 lift when rotating, and the greater the amount of oil flowing out through the oil outlet channel 311. At the same time, when the counterweight plate 331 moves away from the center of the wheel hub 310, it can extend out of the sliding groove, push the oil absorption ring 320 to deform, and then increase its contact area with the yarn 410, and ensure the coating effect when the yarn 410 moves faster.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
