Description

Technical Field

[0001] This invention relates to the technical field of oil dripping devices for twisting machines, specifically an oil dripping device for twisting machines. Background Technology

[0002] During the production of cables, multiple strands of wire are twisted together using a twisting machine to form a cable. Twisting includes unwinding, guiding and laying the wires, twisting (stretching), clamping, oiling, and take-up. During the twisting process, several limiting wheels and twisting points limit the wires from various directions, causing them to converge into a single strand before twisting. To ensure lubrication, heat dissipation, rust prevention, and protection of the wire, oil is applied to the twisting points during the twisting process. Before oiling, the twisted strands are clamped. Clamping is primarily to coordinate with the dynamic rhythm of the twisting, ensuring a tight and uniform twist while avoiding excessive constraint that could damage the wire. During the twisting process, clamping and oil dripping of the cable need to be performed alternately. To avoid the oil dripper affecting the clamping mechanism during clamping, the oil dripper's drip head needs to be moved away during clamping. After the clamping mechanism has finished clamping, the oil dripper is reset. The existing technology uses a PLC control system to control the oil dripper to close and move its drip head away when the clamping mechanism performs the clamping action. However, there is still a distance between the oil dripper's drip head and the valve. Therefore, when the oil dripper closes the oil outlet and moves the drip head, there is still residual oil in the dripper's drip tube. This oil continues to drip even when the drip head is away from the dripping point of the cable, resulting in waste. Summary of the Invention

[0003] To address the technical problems mentioned in the background section, the present invention provides an oil dripping device for a twisting machine, employing the following technical solution:

[0004] It includes an oil dripper, which is equipped with a driver. The oil dripper includes a connecting pipe, which is equipped with a ball valve. A gear is fixedly connected to the valve stem of the ball valve. A metal pipe is connected to the connecting pipe below the ball valve. An oil dripping pipe is connected to the metal pipe. The oil dripping pipe is mounted on the driver and has an oil dripping head connected to it.

[0005] Furthermore, the drip line is made of carbon steel.

[0006] Furthermore, a hose is connected to the connector, and an oil drip bottle is connected to the hose.

[0007] Furthermore, the actuator includes a cylinder, with a lower bearing and an upper bearing fixed to the inner wall of the cylinder. A rotating cylinder is fixed to the inner ring of the lower bearing and the upper bearing. The bottom of the rotating cylinder extends to the lower side of the cylinder. A rotating rod is fixedly connected to the bottom end of the rotating cylinder. A spiral groove is opened on the rotating cylinder. A lifting rod is movably connected inside the rotating cylinder. A pin is fixedly connected to the lifting rod. The pin is movably arranged in the spiral groove. A circular limiting plate is fixedly connected to the lifting rod. A spring is movably sleeved on the lifting rod. One end of the spring is fixedly connected to the upper part of the upper bearing, and the other end is fixedly connected to the bottom of the circular limiting plate. A driving component is provided inside the cylinder. The driving component is located above the circular limiting plate. An elongated hole is opened on the cylinder. One end of the driving component passes through the elongated hole and meshes with a gear.

[0008] Furthermore, the driving component includes a cylinder, the telescopic end of which is located above the circular limiting plate. A connecting plate is provided on the cylinder and is connected to the inner wall of the cylinder. A connecting rod is fixedly connected to the telescopic end of the cylinder. The connecting rod passes through an elongated hole and a rack is fixedly connected to the end of the connecting rod. The rack is provided with some rack teeth and intermittently meshes with the gear.

[0009] Furthermore, a placer is fixedly connected to the rotating rod, and the placer has a semi-circular hole made of elastic rubber, into which the oil drip tube is inserted.

[0010] Furthermore, a fixing rod is fixedly connected through the cylinder, and a semi-circular groove is fixedly connected to the ball valve. The semi-circular groove is made of elastic rubber, and one end of the fixing rod is engaged in the semi-circular groove.

[0011] Furthermore, a hinge joint is fixedly connected to the fixed rod, a hinge shaft is rotatably connected to the hinge joint, and a hinge is fixedly connected to the hinge shaft.

[0012] This invention has the following advantages: When the driver drives its telescopic end to descend, it first drives the gear on the ball valve rod to rotate, causing the ball valve to close and stop the oil supply. Then, the connection between the driver and the gear disengages, allowing the oil remaining in the dripping tube to continue dripping during the period when the oil supply to the dripper stops. Just as the oil remaining in the dripping tube has finished dripping, the telescopic end of the driver continues to descend, driving the dripping tube to rotate, causing the dripping head on the dripping tube to leave the dripping point of the twisting machine. This invention ensures that no residual oil drips out when the dripping head rotates away by first closing the ball valve and then causing the dripping head to leave the dripping point of the twisting machine. Secondly, this structure can accurately control the interval between the ball valve closing and the dripping head rotating, avoiding the interval being too fast or too slow, which would affect the clamping of the twisting machine clamping mechanism on the twisting of the cable.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please refer to Figure 1-8This invention discloses an oil dripping device for a twisting machine, including an oil dripper with a driver. The oil dripper includes a connecting pipe 1, a ball valve 2 on the connecting pipe 1, and the ball valve 2 controls the opening and closing of the connecting pipe 1. A gear 3 is fixedly connected to the valve stem of the ball valve 2. The rotation of the gear 3 drives the rotation of the valve stem, thereby opening or closing the ball valve 2. A metal pipe 4 is connected to the connecting pipe 1 below the ball valve 2, and an oil dripping pipe 5 is connected to the metal pipe 4. The metal pipe 4 can fix the oil dripping pipe 5. The oil dripping pipe 5 is mounted on the driver and has an oil dripping head 6 connected to it. When the oil in the oil dripping pipe 5 enters the oil dripping head 6, it can drip out from the oil dripping head 6. The oil dripping pipe 5 is made of carbon steel. This material makes the oil dripping pipe 5 hard, which ensures that the oil dripping pipe 5 will not be flattened and allows it to be bent at will. A hose 7 is connected to the connecting pipe 1, and an oil dripping bottle 8 is connected to the hose 7. The oil in the oil dripping bottle 8 enters the connecting pipe 1 through the hose 7.

[0024] The actuator includes a cylinder 9, with a lower bearing 10 and an upper bearing 30 fixed to the inner wall of the cylinder 9. The cylinder 9 serves as a fixed outer shell. A rotating cylinder 11 is fixed to the inner ring of the bearings 10 and 30. When the cylinder 9 is stationary, the rotating cylinder 11 can rotate on the lower bearings 10 and 30. The bottom of the rotating cylinder 11 extends to the lower side of the cylinder 9. A rotating rod 12 is fixedly connected to the bottom end of the rotating cylinder 11. When the rotating cylinder 11 rotates, it drives the rotating rod 12 to rotate. A spiral groove 13 is provided on the rotating cylinder 11. A lifting rod 14 is movably connected inside the rotating cylinder 11. A pin 15 is fixedly connected to the lifting rod 14 and is movably disposed in the spiral groove 13. A circular limiting plate 16 is fixedly connected to the lifting rod 14. When the circular limiting plate 16 is pressed, the lifting rod 14 descends accordingly. The lifting rod 14 drives the pin 15 to descend. The pin 15 slides adaptably in the spiral groove 13. The spiral groove 13 drives the rotating drum 11 to rotate counterclockwise. A spring 17 is movably sleeved on the lifting rod 14. One end of the spring 17 is fixedly connected to the upper part of the upper bearing 30, and the other end is fixedly connected to the bottom of the circular limiting plate 16. The spring 17 does not contact the inner ring of the upper bearing 30. Therefore, the compression or rebound of the spring 17 does not affect the rotation of the rotating drum 11. A driving component is provided inside the cylinder 9. The driving component is located on the upper side of the circular limiting plate 16. When the driving component leaves the circular limiting plate 16, the spring 17 rebounds. An elongated hole 18 is provided on the cylinder 9. One end of the driving component can move up and down in the elongated hole 18. One end of the driving component passes through the elongated hole 18 and is meshed with the gear 3.

[0025] The driving component includes a cylinder 19. The telescopic end of the cylinder 19 is located on the upper side of the circular limiting plate 16. The telescopic end of the cylinder 19 only contacts the circular limiting plate 16 when it descends to a certain position. A connecting plate 20 is provided on the cylinder 19 and is connected to the inner wall of the cylinder 9. The cylinder 19 is suspended and fixed inside the cylinder 9 through the connecting plate 20. A connecting rod 21 is fixedly connected to the telescopic end of the cylinder 19. The connecting rod 21 rises and falls with the telescopic end of the cylinder 19. The connecting rod 21 passes through an elongated hole 18 and can rise and fall within the elongated hole 18. A rack 22 is fixedly connected to the end of the connecting rod 21. The rack 22 is provided with some rack teeth. The rack 22 is intermittently meshed with the gear 3. When the rack 22 descends, its rack teeth mesh with the gear 3, causing the gear 3 to rotate. The rotation of the gear 3 drives the ball valve 2 to close. When the ball valve 2 is closed, the rack teeth on the rack 22 just leave the gear 3 and no longer drive the gear 3.

[0026] A placer 23 is fixedly connected to the rotating rod 12. The placer 23 is provided with a semi-circular hole 24. The semi-circular hole 24 is made of elastic rubber. The oil drip tube 5 is clamped in the semi-circular hole 24. By pressing the oil drip tube 5 into the semi-circular hole 24, and through its elastic rubber material, the oil drip tube 5 can be elastically clamped and is easy to remove from the semi-circular hole 24.

[0027] A fixing rod 25 is fixedly connected through the cylinder 9, and the cylinder 9 is suspended and fixed by the fixing rod 25. A semi-circular groove 26 is fixedly connected to the ball valve 2. The semi-circular groove 26 is made of elastic rubber. One end of the fixing rod 25 is inserted into the semi-circular groove 26. By pressing the fixing rod 25 into the semi-circular groove 26 and through its elastic rubber material, one end of the ball valve 2 can be elastically clamped and fixed, and it is easy to separate the ball valve 2 from the fixing rod 25, so that the entire oil dripper can be removed.

[0028] A hinge joint 27 is fixedly connected to the fixed rod 25. A hinge shaft 28 is rotatably connected to the hinge joint 27. A hinge seat 29 is fixedly connected to the hinge shaft 28. One end of the hinge seat 29 is fixed to the twisting machine. When the fixed rod 25 rotates, it drives the hinge shaft 28 to rotate on the hinge joint 27, which makes it easy to adjust the position of the entire oil dripper.

[0029] Working principle of the invention:

[0030] First, the principle of the oil dripper is that the oil in the oil bottle 8 enters the connector 1 through the hose 7, enters the metal tube 4 through the ball valve 2, enters the oil dripping tube 5, and then drips out through the oil dripping head 6.

[0031] During operation, cylinder 19 is activated. As the telescopic end of cylinder 19 slowly descends, it drives connecting rod 21 to descend within elongated hole 18. Connecting rod 21 drives rack 22 to descend, and the rack teeth of rack 22 mesh with gear 3. Gear 3 rotates and drives valve stem to rotate, causing valve stem to close ball valve 2, preventing oil from dripping from dripping bottle 8 into dripping pipe 5. The oil remaining in dripping pipe 5 continues to drip onto the oil dripping point of twisting machine, while the telescopic end of cylinder 19 and rack 22 continue to descend slowly. During this period, when ball valve 2 is closed, the rack teeth of rack 22 disengage from gear 3. When the descending telescopic end of cylinder 19 contacts circular limit plate 16, the oil remaining in dripping pipe 5 is completely dripped through dripping head 6. Circular limit plate 16 descends under the pressure of telescopic end of cylinder 19, spring 17 is compressed, and circular limit plate 16 drives lifting rod 14 and pin 15 on lifting rod 14 to descend. As the screw 15 slides within the spiral groove 13, the spiral groove 13 drives the rotating drum 11 to rotate counterclockwise within the inner rings of the lower bearing 10 and the upper bearing 30. The rotating drum 11 drives the rotating rod 12 to rotate counterclockwise, and the rotating rod 12 drives the placer 23 and the oil dripping pipe 5 on the placer 23 to rotate counterclockwise, causing the oil dripping head 6 to leave the oil dripping point of the twisting machine. The clamping mechanism on the twisting machine begins to clamp the cable. Then, the telescopic end of the cylinder 19 moves upward again. Under the rebound of the spring 17, the spring 17 drives the circular limit plate 16 and the screw 15 to move upward, causing the rotating drum 11 to rotate clockwise again. Just as the clamping mechanism on the twisting machine has completed the clamping action, the oil dripping head 6 returns to the oil dripping point of the twisting machine, while the telescopic end of the cylinder 19 continues to move upward, driving the rack teeth on the rack 22 to mesh with the gear 3. The gear 3 rotates in the opposite direction, causing the ball valve 2 to reopen, and the oil dripping head 6 begins to drip oil again.

[0032] This invention is simple to operate, convenient to use, and suitable for widespread promotion and application. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
