Description

Technical Field

[0001] This invention relates to the field of cable production technology, specifically a high-uniformity coating equipment and its application in enameled wire production. Background Technology

[0002] In the continuous manufacturing process of power cables, uniformly coating the surface of the conductor with an insulating varnish is considered a key step to improve linear insulation and protective performance. Currently, the industry commonly uses two methods: brush roller contact coating and nozzle non-contact spraying. The brush roller method suffers from the problem that the conductor surface always carries fine dust, which continuously migrates to and accumulates on the brush roller during continuous operation, clogging the pores of the brush layer and causing the varnish film thickness to become uncontrollable, ultimately leading to a decline in coating quality. Nozzle spraying, on the other hand, avoids the shortcoming of dust accumulation, and therefore its application has rapidly expanded.

[0003] However, the nozzle process is not without its flaws. The insulating varnish, after high-pressure atomization, easily accumulates in localized areas of the traveling wire core, forming nodular protrusions. This causes a momentary imbalance in the insulation film thickness, directly reducing the consistency of the finished product. To suppress these nodules, existing technologies introduce hollow ultrasonic needles. These needles use high-frequency cavitation to instantly pierce the surface film of the nodules and simultaneously apply negative pressure suction to remove excess varnish. However, practical experience shows that as the number of batches increases, residual varnish gradually adheres to the inner and outer walls of the ultrasonic needle. It first forms a flexible buffer film, weakening the cavitation rupture effect, and then deposits and thickens, significantly increasing the needle tip diameter. This not only weakens the nodule removal capability but also induces new surface defects in subsequent processes. Summary of the Invention

Two sets of elastic drive components are provided and installed on the connecting frame. The elastic drive components are connected to the hollow ultrasonic needle, and the elastic drive components have a first state and a second state that are pulled and switched. When the elastic drive components are in the first state, the hollow ultrasonic needle is directly below the cable. The first transmission component is connected to the elastic drive assembly; A power assembly is mounted on the connecting frame. The power assembly is equipped with a second transmission component adapted to the first transmission component, and the power assembly is capable of driving the two sets of elastic drive components to move alternately.

[0006] As a further aspect of the present invention: the elastic drive component includes: A horizontal shaft is fixedly installed on the connecting frame, and an elastic sliding structure is provided on the horizontal shaft.

The collars are fixedly connected to the hollow ultrasonic needle, and the collars are provided with guide parts that slide with the first convex shaft.

[0007] As a further embodiment of the present invention: the elastic sliding structure includes a transverse sliding ring sleeved on the transverse shaft, the transverse sliding ring being fixedly connected to the first convex shaft, and a limiting block being provided on the inner wall of the transverse sliding ring, the limiting block being slidably engaged with a limiting groove provided on the transverse shaft.

[0008] As a further embodiment of the present invention: the elastic sliding structure further includes a stop ring and a cylindrical spring disposed on the horizontal axis, one end of the cylindrical spring being connected to the horizontal moving ring and the other end being connected to the stop ring.

[0009] As a further embodiment of the present invention: the guide portion includes two sets of inclined portions disposed on the collar, a protrusion is formed between the two sets of inclined portions, and a limiting portion is provided at the end of the two sets of inclined portions away from the protrusion.

[0010] As a further embodiment of the present invention: a first gear coaxial with the collar is fixedly mounted on the collar, and a second gear is fixedly mounted on the power assembly, wherein the first gear meshes with the second gear; The first gear and the second gear form the first transmission component and the second transmission component.

[0011] As a further embodiment of the present invention: the power assembly includes a drive device fixedly mounted on the connecting frame, the output shaft of the drive device is connected to a drive shaft rotatably mounted on the connecting frame, a follower is fixedly mounted on the drive shaft, and a second convex shaft is provided on both sides of the follower; The power assembly also includes a follower ring that is coaxially and fixedly connected to the second transmission component.

[0014] The application of the high uniformity coating equipment described above in enameled wire production.

[0015] Compared with the prior art, the beneficial effects of the present invention are: By using the elastic drive component, when the hollow ultrasonic needle switches from a vertical to a horizontal state, the elastic potential energy released by the cylindrical spring is used to quickly drive the hollow ultrasonic needle to move. This allows the hollow ultrasonic needle to deflect rapidly. At this time, the paint adhering to the outside of the hollow ultrasonic needle can be thrown off under the action of centrifugal force, thereby separating the paint from the hollow ultrasonic needle. This prevents the paint from accumulating in the hollow ultrasonic needle, which would cause the end of the hollow ultrasonic needle to become swollen and cause other process defects in subsequent use. At the same time, it prevents the ultrasonic field from failing and causing the end of the hollow ultrasonic needle to be unable to break the paint film. By designing a power component, the two sets of hollow ultrasonic needles can be in a vertical position simultaneously during the switching process, thus ensuring that the two sets of hollow ultrasonic needles can work continuously. This prevents the lacquer lumps on the cable from being left unremoved at a certain moment due to a gap in operation during the switching process, thereby guaranteeing the treatment effect of the lacquer lumps.

[0026] 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.

[0027] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0028] In this embodiment of the invention, a high-uniformity coating device includes: a frame 1, a connecting frame 10, an elastic drive component, a first transmission component, and a power component. When the hollow ultrasonic needle 13 switches from a vertical to a horizontal state, and the cylindrical spring 16 releases elastic potential energy to rapidly drive the hollow ultrasonic needle 13, the hollow ultrasonic needle 13 can deflect rapidly. At this time, the paint adhering to the outside of the hollow ultrasonic needle 13 can be thrown off under the action of centrifugal force, thereby separating the paint from the hollow ultrasonic needle 13. This prevents paint from accumulating in the hollow ultrasonic needle 13, causing the end of the hollow ultrasonic needle 13 to become enlarged and leading to other process defects in subsequent use. Simultaneously, it prevents the ultrasonic field from failing, thus preventing the end of the hollow ultrasonic needle 13 from failing to break the paint film. Specifically, as follows: Please see Figures 1-9 The frame 1 is equipped with a guide component and a spraying component. The guide component can guide the movement of the cable. A near-infrared generating device 6 is provided between the guide component and the spraying component. The guiding component includes multiple sets of brackets 2 fixedly installed on the frame 1. Each set of brackets 2 is respectively provided with a first guide roller group 3 and a second guide roller group 4. The second guide roller group 4 is connected to a pumping device 5 provided on the frame 1. It should be noted that the height of the second guide roller group 4 is lower than the height of the first guide roller group 3, so that when the cable is pulled, the cable has an inclined section. This inclined section allows the paint lumps generated on the cable to move from top to bottom along the length of the cable and be collected by the hollow ultrasonic needle 13 when they reach the lower end of the cable. This prevents the paint lumps from remaining on the cable and dripping during the cable movement, ensuring that residual paint can be effectively collected.

[0029] It should be further explained that, during the movement of the cable, from the perspective of a single point, that point also moves from top to bottom along the inclined section of the cable. That is, the movement of the lacquer lumps depends on both their own gravity and the movement of the cable, and the speed of the cable is greater than the speed of the lacquer lumps themselves.

[0030] Furthermore, the aforementioned second guide roller group 4 is an air-bearing guide roller. Specifically, the interior of the second guide roller group 4 is a hollow structure and is connected to the air pumping device 5. When the guide cable moves, the second guide roller group 4 can reduce the pressure between itself and the cable by spraying compressed gas, thereby preventing the uncured paint film from being "flattened" or "scratched" by the roller.

[0031] Furthermore, under the action of the near-infrared generating device 6, the paint sprayed onto the cable can be cured quickly. During this curing process, the phenomenon of the paint film on the cable being "flattened" or "scratched" by the roller is also prevented.

[0032] The spraying assembly includes a paint pump circulation device 9 fixedly installed on the frame 1 and a spraying component 7 fixedly connected to the paint pump circulation device 9. The spraying component 7 has multiple sets of spray nozzles 8 arranged equidistantly around its circumference.

[0033] In this embodiment, when the cable is pulled and moves, the spraying component 7 can maintain a coaxial state with the cable. At this time, the circumferentially arranged nozzle 8 can spray the paint sprayed by the pump paint circulation device 9 onto the cable in a circumferential manner. In conjunction with the movement of the cable, the paint can be evenly coated along the length of the cable.

[0034] In this case, the nozzle 8 is not perpendicular to the length of the cable, but faces the direction of the cable's movement. When a paint lump is generated on the cable, the paint lump can move along the inclined section of the cable under the action of the airflow generated by the nozzle 8 spraying paint, thereby assisting the movement of the paint lump and facilitating the collection by the hollow ultrasonic needle 13.

[0035] Furthermore, when the paint is sprayed onto the cable, the airflow generated by the spray nozzle 8 causes the paint to tend to separate from the cable during the initial formation of the paint nodules. At this time, during the separation of the paint nodules from the cable, the cable is still within the coverage area of ​​the spraying component 7, allowing the dripping airflow to fall into the spraying component 7. In this embodiment, the bottom of the spraying component 7 is also provided with a return pipe connected to the paint pump circulation device 9. The return pipe can circulate the paint that forms the paint nodules to the paint pump circulation device 9, thereby realizing the recycling of this part of the paint.

[0036] Please see Figures 4-7 The connecting frame 10 is mounted on the frame 1, and two sets of deflectable hollow ultrasonic needles 13 are mounted on the connecting frame 10. Two sets of the elastic drive components are provided and installed on the connecting frame 10. The elastic drive components are connected to the hollow ultrasonic needle 13, and the elastic drive components have a first state and a second state that are pulled and switched. When the elastic drive components are in the first state, the hollow ultrasonic needle 13 is directly below the cable.

[0037] In the initial state, of the two sets of hollow ultrasonic needles 13, only one set of hollow ultrasonic needles 13 is in a vertical state, while the other set of hollow ultrasonic needles 13 is in a horizontal state. The upper end of the hollow ultrasonic needle 13 in the vertical state is attached to the lower part of the cable (there is a predetermined gap between the two). When the lacquer lump moves to the upper part of the hollow ultrasonic needle 13, the ultrasonic vibration generated by the hollow ultrasonic needle 13 can first cause the lacquer lump film formed on the surface of the lacquer lump to rupture. Then, a negative pressure will be generated inside the hollow ultrasonic needle 13. At this time, under the action of the negative pressure, the lacquer lump can be drawn away through the hollow ultrasonic needle 13 and circulated into the lacquer circulation device 9. The elastic drive component includes: A horizontal shaft 11 is fixedly installed on the connecting frame 10. An elastic sliding structure is provided on the horizontal shaft 11. A first convex shaft 15 is fixedly installed at one end of the elastic sliding structure. The elastic sliding structure includes a transverse moving ring 14 sleeved on the horizontal shaft 11. The transverse moving ring 14 is fixedly connected to the first convex shaft 15. A limit block 1401 is also provided on the inner wall of the transverse moving ring 14. The limit block 1401 slides in cooperation with the limit groove 1101 provided on the horizontal shaft 11. Under the above configuration, the axial uniformity of the transverse moving ring 14 and the horizontal shaft 11 can be guaranteed. That is, the transverse moving ring 14 cannot rotate axially relative to the horizontal shaft 11, but can only move along the length direction of the horizontal shaft 11. This ensures the axial stability of the first convex shaft 15 relative to the horizontal shaft 11 when the collar 12 rotates to drive the first convex shaft 15 to move, and ensures the positional accuracy after the collar 12 rotates to the predetermined position.

[0038] The elastic sliding structure also includes a stop ring 1102 and a cylindrical spring 16 disposed on the horizontal shaft 11. One end of the cylindrical spring 16 is connected to the horizontal moving ring 14, and the other end is connected to the stop ring 1102. Two sets of collars 12 are rotatably mounted on the horizontal shaft 11. The collars 12 are fixedly connected to the hollow ultrasonic needle 13, and the collars 12 are provided with guide portions that slide with the first convex shaft 15. The guide portions include two sets of inclined portions 1202 provided on the collars 12. A protrusion 1203 is formed between the two sets of inclined portions 1202, and a limiting portion 1201 is provided at the end of the two sets of inclined portions 1202 away from the protrusion 1203. During the rotation of the collars 12, the first convex shaft 15 can move along the inclined portion 1202 toward the protrusion 1203. During this process, the first convex shaft 15 will drive the transverse moving ring 14 to make way and further compress the cylindrical spring 16.

[0039] In this embodiment, in the initial state, the cylindrical spring 16 is in a compressed state, and one set of hollow ultrasonic needles 13 is in a vertical state, while the other set of hollow ultrasonic needles 13 is in a horizontal state. In this state, the corresponding first convex shaft 15 is located within the corresponding limiting part 1201, so that under the elastic force provided by the cylindrical spring 16, the two sets of hollow ultrasonic needles 13 can ensure the stability of their respective states.

[0040] When the power component is activated, it drives the collar 12 connected to the hollow ultrasonic needle 13 to rotate. The collar 12 then causes the hollow ultrasonic needle 13 to move in a circular motion along the horizontal axis 11. During this process, the collar 12 moves relative to the first convex shaft 15, allowing the first convex shaft 15 to separate from the limiting part 1201 and move along the inclined part 1202. At this time, the transverse moving ring 14 moves towards the stop ring 1102 along the length of the horizontal axis 11, further compressing the cylindrical spring 16. As the collar 12 rotates, the first convex shaft 15 can move to the protrusion 1203. At this point, the cylindrical spring... When the spring 16 is compressed to its maximum extent, and then the collar 12 continues to rotate at a certain angle, the first convex shaft 15 will be on another inclined portion 1202. At the same time, the cylindrical spring 16 actively releases its elastic potential energy, causing the first convex shaft 15 to move along the inclined portion 1202, thereby enabling the hollow ultrasonic needle 13 to deflect rapidly. That is, in this embodiment, after the first convex shaft 15 moves from one of the inclined portions 1202 past the protrusion 1203, the first convex shaft 15 can accelerate along the other inclined surface during the process of the cylindrical spring 16 releasing its elastic potential energy. In this process, the following advantages are available: When the hollow ultrasonic needle 13 switches from a vertical state to a horizontal state, and the cylindrical spring 16 releases elastic potential energy to quickly drive the hollow ultrasonic needle 13 to move, the hollow ultrasonic needle 13 can be deflected quickly. At this time, the paint adhering to the outside of the hollow ultrasonic needle 13 can be thrown off under the action of centrifugal force, so that the paint can be separated from the hollow ultrasonic needle 13. This avoids the paint from accumulating in the hollow ultrasonic needle 13, causing the end of the hollow ultrasonic needle 13 to become bloated and causing other process defects in subsequent use. At the same time, it avoids the ultrasonic field failure causing the end of the hollow ultrasonic needle 13 to be unable to break the paint film.

[0041] Please see Figures 8-9 The first transmission component is connected to the collar 12; The power assembly is mounted on the connecting frame 10, and the power assembly is provided with a second transmission component adapted to the first transmission component. The power assembly is capable of driving the two sets of elastic drive components to move alternately. A first gear 17 coaxial with the collar 12 is fixedly installed on the collar 12, and a second gear 18 is fixedly installed on the power assembly. The first gear 17 meshes with the second gear 18. The first gear 17 and the second gear 18 form the first transmission component and the second transmission component; The power assembly includes a drive device 22 fixedly mounted on the connecting frame 10. The output shaft of the drive device 22 is connected to a drive shaft 20 rotatably mounted on the connecting frame 10. A follower 21 is fixedly mounted on the drive shaft 20. A second convex shaft 2101 is provided on both sides of the follower 21. The power assembly also includes a follower ring 19 coaxially and fixedly connected to the second transmission component. The follower ring 19 is provided with an arc-shaped groove 1901, and the second convex shaft 2101 can slide within the arc-shaped groove 1901.

[0042] For ease of understanding, Figure 8 For reference, the two sides of the follower 21 are named the left side and the rear side, respectively. In the initial state, if the hollow ultrasonic needle 13 on the right side is in a vertical state, the second convex shaft 2101 on the right side is at the end of the arc groove 1901 away from its direction of movement. At this time, the hollow ultrasonic needle 13 on the left side is in a horizontal state, and the second convex shaft 2101 on the left side is at the end of the arc groove 1901 facing its direction of movement. When the drive device 22 rotates through the drive shaft 20 and the follower 21, the second convex shaft 2101 can rotate in a circular motion. During this process, the second convex shaft 2101 on the left side abuts against one end of the arc groove 1901, so that in the initial stage of the movement of the second convex shaft 2101, the second convex shaft 2101 can drive the follower ring 19 and the second gear 18 on the left side to rotate through the cooperation with the end of the arc groove 1901, thereby driving the collar 12 on the left side to rotate. During this process, the second convex shaft 2101 on the right side will rotate in a circular motion. The movement within the arc-shaped groove 1901 allows the hollow ultrasonic needle 13 on the right side to maintain its original stable state. When the second convex shaft 2101 on the left side drives the second gear 18 to rotate more than 45°, the cylindrical spring 16 will release elastic potential energy and actively drive the hollow ultrasonic needle 13 on the left side to deflect until the hollow ultrasonic needle 13 is vertical. After that, the follower 21 will continue to move. At this time, the second convex shaft 2101 on the right side is in contact with one end of the arc-shaped groove 1901, causing the collar 12 on the right side to rotate, thus switching the hollow ultrasonic needle 13 on the right side from a vertical state to a horizontal state. Based on the above process, it is not difficult to see that during the switching process of the two sets of hollow ultrasonic needles 13, there is a process in which both are in a vertical state at the same time. This allows the two sets of hollow ultrasonic needles 13 to have the effect of continuous operation, preventing the lacquer lumps on the cable from not being removed at a certain moment due to the working gap during the switching process, thus ensuring the treatment effect of the lacquer lumps.

[0043] It is worth noting that the first gear 17 and the second gear 18 mentioned above have the same circumferential radius and number of teeth, and the arc angle of the arc groove 1901 is greater than 45°, so that the ring 12 will not be blocked by the contact between the arc groove 1901 and the second convex shaft 2101 during the active rotation.
