Description

Technical Field

[0001] The utility model relates to the technical field of enameled wire lubrication, in particular to an automatic lubrication device for enameled wire production. Background Art

[0002] Enameled wire is a main type of winding wire, which consists of a conductor and an insulating layer. The bare wire is annealed and softened, then painted and baked several times. The production of enameled wire requires multiple processes, and a lubricating device is required to lubricate its surface during the production process to prevent the enameled wire from being scratched due to excessive surface friction during production and movement.

[0003] After searching, it is found that a controllable automatic lubrication device for enameled wire production disclosed in announcement number CN218602179U is provided, which drips oil to one side of a sponge block to wet the sponge block, and ensures the lubrication effect by making the sponge block close to the enameled wire. However, since the contact area between the dripping tube and the sponge block is small, supplying oil to the sponge block through the dripping tube will result in different oil contents in different parts of the sponge block. When the sponge block contacts the enameled wire, the lubricating oil contacted by each angle of the outer circumference of the enameled wire is uneven, resulting in poor lubrication effect. In view of this, we propose an automatic lubrication device for enameled wire production. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-Figure 5 , a technical solution provided by the utility model:

[0031] An automatic lubrication device for enameled wire production includes a housing 1, a cavity is provided in the housing 1 for containing lubricating oil, an oil filling port 4 is provided at the top of the housing 1 for adding lubricating oil into the cavity, and an end cap is provided at the top of the oil filling port 4 for closing the oil filling port 4. At least one side of the housing 1 is made of transparent material, so that the user can observe the liquid level inside the housing 1 and add lubricating oil into it in time.

[0032] As an embodiment, a contact mechanism 2 is disposed in the housing 1 , and a through hole is disposed at the axis of the contact mechanism 2 for the enameled wire to pass through.

[0033] Specifically, the contact mechanism 2 in this embodiment includes a felt tube 21, both ends of the felt tube 21 are fixedly connected with a threaded plate 22, and both threaded plates 22 are threadedly connected to the inner wall of the housing 1, and the outer end of one threaded plate 22 is fixedly connected with a plurality of convex plates 23, and the plurality of convex plates 23 are distributed in a circular array with the axis of the felt tube 21 as the center, so that the user can rotate the threaded plate 22 to disassemble and assemble the contact mechanism 2. Through holes are punched through both ends of the felt tube 21, and the inner diameter of the through hole is not greater than the diameter of the enameled wire, so that after the enameled wire passes through the contact mechanism 2, the inner wall of the felt tube 21 can contact the surface of the enameled wire, so that the lubricating oil is applied to the enameled wire. Through holes are set at the axis of the two threaded plates 22, and the inner diameter of the through hole is greater than the diameter of the enameled wire, so as to avoid the enameled wire from contacting the threaded plate 22 after passing through, and prevent the threaded plate 22 from scratching the enameled wire.

[0034] As one embodiment, an oil supply mechanism 3 is provided on the shell 1, and oil is supplied to the felt cylinder 21 through the oil supply mechanism 3, which can ensure the uniformity of the lubricating oil on the surface of the felt cylinder 21 and avoid excessive oil supply.

[0035] Specifically, the oil supply mechanism 3 in this embodiment includes a first rotating cylinder 31 and a second rotating cylinder 32 sleeved on the first rotating cylinder 31, wherein a first oil outlet hole 311 is provided on the first rotating cylinder 31, and a second oil outlet hole 321 is provided on the second rotating cylinder 32, and the first oil outlet hole 311 and the second oil outlet hole 321 can move relative to each other. The first oil outlet hole 311 and the second oil outlet hole 321 can overlap through relative movement, so that the lubricating oil in the housing 1 can contact the felt cylinder 21 through the two oil outlet holes. The first oil outlet hole 311 and the second oil outlet hole 321 can also be staggered through relative movement, thereby stopping the oil supply to the felt cylinder 21 to prevent excessive lubricating oil.

[0036] Furthermore, the first rotating cylinder 31 is sleeved on the felt cylinder 21, and protrusions are formed on both ends of the first rotating cylinder 31, which are rotatably connected to the inner wall of the shell 1, so that the first rotating cylinder 31 can rotate relative to the shell 1 and prevent the first rotating cylinder 31 from detaching from the shell 1.

[0037] Combination Figure 3 and Figure 5As shown, two annular grooves 11 are provided in the housing 1, and the two ends of the second rotating cylinder 32 are respectively inserted in the two annular grooves 11. The second rotating cylinder 32 can rotate in the annular groove 11 and can move axially in the annular groove 11. An elastic sleeve 33 is sleeved on the portion of the second rotating cylinder 32 located in the annular groove 11. The elastic sleeve 33 is made of rubber material and has a certain elasticity. The outer wall of the elastic sleeve 33 fits the inner wall of the annular groove 11. The elasticity of the rubber material can increase the friction between the second rotating cylinder 32 and the annular groove 11, thereby preventing the second rotating cylinder 32 from moving randomly in the annular groove 11 and improving the stability of the structure.

[0038] Furthermore, a slide groove 312 is formed on the outer circumference of the first rotating cylinder 31, and a protrusion 322 is formed on the inner circumference of the second rotating cylinder 32. The protrusion 322 is embedded in the slide groove 312. When the second rotating cylinder 32 rotates, the first rotating cylinder 31 can be driven to rotate synchronously through the protrusion 322 and the slide groove 312. In addition, the protrusion 322 is slidably connected to the inner wall of the slide groove 312, so that the second rotating cylinder 32 can move axially relative to the first rotating cylinder 31, so that the second oil outlet hole 321 is staggered with the first oil outlet hole 311.

[0039] As an embodiment, a rotating assembly 34 is connected to the second rotating drum 32 for driving the second rotating drum 32 and the first rotating drum 31 to rotate.

[0040] Combination Figure 5 As shown, the rotating assembly 34 includes a rotating rod 341 rotatably connected to the inner wall of the shell 1, one end of the rotating rod 341 penetrates into the interior of the shell 1 and is fixedly connected to a gear 342, a circle of teeth 343 is provided on the outer circumference of the second rotating drum 32, and the gear 342 is engaged with the second rotating drum 32 through the teeth 343, thereby driving the second rotating drum 32 to rotate.

[0041] Furthermore, the rotating assembly 34 also includes a fixed sleeve 347 fixedly connected to the housing 1, and a sliding sleeve 346 is slidably connected to the inner wall of the fixed sleeve 347. A motor 345 is fixedly connected inside the sliding sleeve 346, and the output shaft of the motor 345 is connected to the rotating rod 341 to drive the gear 342 to rotate. Both ends of the gear 342 are in contact with baffles 344, and one end of the baffle 344 is fixedly connected to the second rotating cylinder 32. When the gear 342 moves along the axial direction of the housing 1, the second rotating cylinder 32 can be driven to move by the two baffles 344, thereby realizing the adjustment of the position of the second oil outlet 321.

[0042] In addition, a pull ring 348 is fixedly connected to one end of the sliding sleeve 346 away from the housing 1, so as to facilitate pulling the sliding sleeve 346 and thus adjust its position.

[0043] When the automatic lubrication device for enameled wire production of the utility model is in use, the sliding sleeve 346 is first pushed into the fixed sleeve 347, and the sliding sleeve 346 synchronously drives the motor 345, the rotating rod 341 and the gear 342 to move, and the gear 342 synchronously drives the teeth 343 to move through the baffle 344, thereby driving the second rotating drum 32 to move, so that the second oil outlet hole 321 on the second rotating drum 32 is staggered with the first oil outlet hole 311 on the first rotating drum 31.

[0044] Then, lubricating oil is added into the housing 1 through the oil filling port 4, so that the lubricating oil completely covers the second rotating cylinder 32. Then, the sliding sleeve 346 is pulled outward through the pull ring 348, and the sliding sleeve 346 synchronously drives the motor 345, the rotating rod 341 and the gear 342 to move in the opposite direction, and the gear 342 drives the second rotating cylinder 32 to move in the opposite direction through the baffle 344 and the teeth 343, so that the second oil outlet 321 overlaps with the first oil outlet 311, and the lubricating oil in the housing 1 enters the felt cylinder 21 through the second oil outlet 321 and the first oil outlet 311. Then start the motor 345, the output end of the motor 345 drives the gear 342 to rotate through the rotating rod 341, the gear 342 drives the second rotating drum 32 to rotate through the meshing with the teeth 343, and the second rotating drum 32 drives the first rotating drum 31 to rotate synchronously through the protrusion 322 and the slide groove 312, so that the angle between the second oil outlet 321 and the first oil outlet 311 is constantly changed, so that the lubricating oil evenly enters the felt cylinder 21 and wets the felt cylinder 21. Finally, the enameled wire is passed through the through hole in the middle of the device, and the enameled wire is guided to move by the external structure. During the movement of the enameled wire, the felt cylinder 21 applies the lubricating oil to the outer surface of the enameled wire.
