Abstract
Description
Technical Field
[0001] This utility model relates to a high-resistivity paint wire rod curing device with anti-corona discharge. Background Technology
[0002] To ensure the operational stability of generators or high-voltage motors under high-temperature and high-voltage environments, high-resistance paint is usually sprayed onto the ends of the stator bars of the generator or high-voltage motor to form a complete high-resistance anti-corona area, which effectively prevents corona and interphase corona.
[0003] Currently, methods for curing high-resistivity varnish on wire rods include hot air blowing, natural air drying, or ultraviolet curing. Regardless of the method, during curing, the wire rod coated with high-resistivity varnish must first be placed on a dedicated support or cart, and then left to cure in the curing equipment. This static placement method is prone to sagging, preventing the high-resistivity varnish from curing evenly on the surface of the wire rod. Furthermore, during the curing process, curing dead zones can easily appear, leading to insufficient curing of the high-resistivity varnish in certain areas, making it prone to peeling off and reducing the anti-corona effect of the high-resistivity varnish. Utility Model Content
[0004] The purpose of this invention is to provide a high-resistivity anti-corona discharge curing device for paint wire rods to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A high-resistivity anti-corona discharge coating rod curing device includes: A processing box is fixedly installed on a material receiving platform, and a toothed belt is provided inside the processing box; Multiple sets of fixed sleeves are equidistantly arranged on the toothed belt. A rotating cylinder is rotatably mounted on the fixed sleeve, and a clamping assembly is provided inside the fixed sleeve. The clamping assembly includes a reset structure and a clamping structure. The reset structure includes a movable cylinder slidably disposed inside the fixed sleeve. The clamping structure is connected to the rotating cylinder. During the process of the wire rod being inserted into the rotating cylinder and pushing the movable cylinder to retract, the movable cylinder can drive the clamping structure to clamp the wire rod. At the same time, the locking assembly provided on the movable cylinder can fix the clamping state of the clamping structure on the wire rod. The processing box is also equipped with an unlocking component. When the toothed belt drives the fixed sleeve to rotate to a designated position, the unlocking component can trigger the locking assembly to release the clamping structure from the wire bar.
[0006] The anti-corona high-resistivity paint wire rod curing equipment described above: the reset structure further includes a fixed rod disposed in the fixed sleeve, the movable cylinder is slidably connected to the fixed rod, and a first spring is sleeved on the fixed rod, one end of the first spring abutting against the fixed sleeve and the other end abutting against the movable cylinder.
[0007] The anti-corona high-resistivity paint bar curing equipment described above: the clamping structure includes a sleeve ring sleeved on the moving cylinder, and multiple sets of hinge rods are equidistantly mounted on the sleeve ring along its circumferential direction. The end of the hinge rod away from the sleeve ring is hinged to a clamping block slidably disposed on the rotating cylinder.
[0008] The anti-corona high-resistivity paint bar curing equipment described above: a gear is also coaxially arranged on the rotating cylinder, and the gear cooperates with the rack plate arranged in the processing box, so that it can rotate relative to the fixed sleeve.
[0009] The anti-corona high-resistivity paint bar curing equipment described above: the locking assembly includes a slide rod disposed on the movable cylinder, a second spring sleeved on the slide rod, one end of the second spring abutting against the end of the slide rod, and the other end abutting against a locking block slidably disposed on the slide rod.
[0010] As described above, the anti-corona high-resistivity paint bar curing equipment has two sets of locking grooves on the fixed sleeve, which are connected by a sliding groove. The locking block cooperates with the locking groove to fix the position of the moving cylinder.
[0011] The anti-corona high-resistivity paint bar curing equipment described above: the unlocking component includes an unlocking block disposed on the processing box, the unlocking block cooperating with a wedge block disposed on the locking block, which can drive the locking block to slide relative to the slide bar.
[0012] Compared with the prior art, the beneficial effects of this utility model are: By setting fixed sleeves at equal intervals on the toothed belt, and utilizing the cooperation between the clamping component and the locking component inside the fixed sleeve, the wire bar can be automatically clamped when it is inserted into the rotating cylinder rotatably mounted on the fixed sleeve, and the wire bar is fixedly connected to the rotating cylinder. During the subsequent movement of the wire bar by the toothed belt, the gear on the rotating cylinder and the rack plate structure in the processing box can drive the rotating cylinder to rotate the wire bar, so that the wire bar rotates synchronously as it passes through the spray box and the curing box. This allows the high-resistance paint to be evenly sprayed onto the entire circumference of the wire bar, while improving the efficiency and quality of curing, and ensuring that the high-resistance paint forms a protective paint with consistent performance on the surface of the wire bar. Furthermore, after the toothed belt drives the bar through the processing box, the locking component cooperates with the unlocking component set on the processing box to automatically release the clamping state of the bar. This process is simple to operate, requiring only manual feeding, and the high-resistance paint spraying and curing processes are carried out in sequence, thereby improving the efficiency of the bar anti-corona treatment.

[0024] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.
[0025] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.
[0026] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.
[0027] Please see Figures 1-10 In this embodiment of the invention, a high-resistivity anti-corona discharge coating rod curing device includes: A processing box 1 is fixedly installed on the material receiving platform 2, and a toothed belt 5 is provided inside the processing box 1; Specifically, please refer to Figure 3 , Figure 4 The toothed belt 5 is fitted onto two sets of synchronous pulleys 4 rotatably mounted inside the processing box 1. One set of synchronous pulleys 4 is coaxially fixed to the output shaft of the motor, which is fixedly mounted on the outer wall of the processing box 1. When the motor starts, the synchronous pulleys 4 can drive the toothed belt 5 to move stably to the left (see reference). Figure 3 describe).
[0028] Multiple sets of fixed sleeves 9 are equidistantly arranged on the toothed belt 5. A rotating cylinder 10 is rotatably mounted on the fixed sleeve 9, and a clamping assembly is provided inside the fixed sleeve 9. The clamping assembly includes a reset structure and a clamping structure. The reset structure includes a movable cylinder 18 slidably disposed inside the fixed sleeve 9. The clamping structure is connected to the rotating cylinder 10. During the process of the wire rod being inserted into the rotating cylinder 10 and pushing the movable cylinder 18 to retract, the movable cylinder 18 can drive the clamping structure to clamp the wire rod. At the same time, the locking assembly provided on the movable cylinder 18 can fix the state of the clamping structure clamping the wire rod. For details, please refer to Figures 5-10 The rotating cylinder 10 and the fixed sleeve 9 are provided with a certain damping so that the rotating cylinder 10 cannot easily rotate relative to the fixed sleeve 9; and an insertion hole 1001 is provided on the side of the rotating cylinder 10 away from the fixed sleeve 9. The insertion hole 1001 is provided with a guide arc surface with a large curvature. The guide arc surface helps the wire bar to be quickly inserted into the rotating cylinder 10, thereby improving the insertion efficiency of the wire bar.
[0029] Furthermore, the processing box 1 is equipped with a spraying box 101 and a curing box 102 arranged from right to left. When the toothed belt 5 moves, the spraying box 101 and the curing box 102 open simultaneously. At this time, the wire rod connected to the toothed belt 5 through the clamping assembly passes through the spraying box 101 and the curing box 102 in turn. When the wire rod passes through the spraying box 101, the high-resistance paint continuously sprayed by the spraying structure in the spraying box 101 will adhere to the surface of the wire rod, and the remainder will fall into the recycling tank 6 set below the spraying box 101. Subsequently, the wire rod with the high-resistance paint is irradiated by ultraviolet light or blown by hot air in the curing box 102, and the surface of the wire rod is cured into a protective paint, which plays a role in preventing corona discharge.
[0030] Further, please refer to Figure 6 , Figure 8 The reset structure further includes a fixed rod 13 disposed in the fixed sleeve 9, the movable cylinder 18 is slidably connected to the fixed rod 13, and a first spring 14 is sleeved on the fixed rod 13, one end of the first spring 14 abuts against the fixed sleeve 9, and the other end abuts against the movable cylinder 18; Specifically, the aforementioned fixed rod 13 is provided with two sets of protrusions 1301 at equal intervals along its circumference. The protrusions 1301 are slidably disposed in the grooves 1801 opened on the inner wall of the movable cylinder 18. With the cooperation of the protrusions 1301 and the grooves 1801, the movable cylinder 18 can only slide along the axial direction of the fixed rod 13. In particular, the aforementioned first spring 14 is always in a compressed state, pushing the movable cylinder 18 to have a tendency to move toward the insertion hole 1001, so that in the initial state, the movable cylinder 18 is close to the insertion hole 1001. During the process of inserting the wire rod into the rotating cylinder 10, the wire rod will push the movable cylinder 18 to retract into the fixed sleeve 9 and trigger the clamping structure to clamp the wire rod, fixing the wire rod to the rotating cylinder 10 so that the wire rod can subsequently follow the toothed belt 5 to move into the processing box 1. The clamping structure includes a sleeve ring 17 sleeved on the movable cylinder 18. The sleeve ring 17 is equidistantly mounted with multiple sets of hinge rods 16 along its circumferential direction. The end of the hinge rod 16 away from the sleeve ring 17 is hinged to the clamping block 15 slidably disposed on the rotating cylinder 10. Specifically, please refer to Figure 9 The clamping block 15 is provided with a T-shaped block 1501, which is slidably disposed in a T-shaped groove opened radially inside the rotating cylinder 10. With the cooperation of the T-shaped block 1501 and the T-shaped groove, the clamping block 15 can only move in the radial direction of the rotating cylinder 10 to clamp or release the wire rod inserted into the rotating cylinder 10. In particular, the inner wall of the clamping block 15 is provided with a rubber pad. When clamping the wire rod, the rubber pad can prevent the clamping block 15 from over-clamping the wire rod and prevent the clamping block 15 from causing clamping damage to the wire rod.
[0031] A gear 12 is also coaxially mounted on the rotating cylinder 10. The gear 12 cooperates with the rack plate 7 disposed in the processing box 1 and can rotate relative to the fixed sleeve 9.
[0032] For details, please refer to Figure 6 , Figure 8 The locking assembly includes a slide rod 21 disposed on the movable cylinder 18, a second spring 22 sleeved on the slide rod 21, one end of the second spring 22 abutting against the end of the slide rod 21, and the other end abutting against the locking block 19 slidably disposed on the slide rod 21; For details, please refer to Figure 6 , Figure 8 , Figure 9 The second spring 22 is always in a compressed state, which pushes the locking block 19 to move toward the outside of the fixed sleeve 9. The locking block 19 is configured as a kind of "right-angled trapezoidal structure" with its inclined surface set as a ramp 1901. The fixed sleeve 9 has two sets of locking grooves 20, which are connected by a sliding groove 3. The locking block 19 cooperates with the locking groove 20 to fix the position of the moving cylinder 18. Specifically, please refer to Figure 7 The aforementioned locking groove 20 includes an inclined surface 2001; In the initial state, the locking block 19 engages with the locking groove 20 near the rotating cylinder 10. At this time, the moving cylinder 18 approaches the insertion hole 1001, and the clamping block 15 opens. When inserting the wire rod, the wire rod pushes the moving cylinder 18 to retract, further compressing the first spring 14. During the retraction process, the sleeve ring 17, with the cooperation of the hinge rod 16, pulls the clamping block 15 to close and clamp the wire rod. At the same time, the ramp 1901 of the locking block 19 is compressed by the inclined surface 2001, retracting towards the inside of the fixed sleeve 9 and compressing the second spring 22 until the ramp 1901 separates from the inclined surface 2001, and the locking block 19 disengages from the locking groove 20. As the wire rod continues to be inserted... Insertion occurs, and the moving cylinder 18 continues to retract until the locking block 19 engages with the next set of locking grooves 20. At this point, the second spring 22 releases its elastic potential energy, pushing the locking block 19 to engage with the locking groove 20 away from the rotating cylinder 10. When the protrusion 1301 moves to the end of the travel of the groove 1801, the clamping block 15 fully retracts to clamp the wire rod. Subsequently, the wire rod is released, and the elastic potential energy stored in the first spring 14 pushes the moving cylinder 18 to move outward so that the vertical surface of the locking block 19 corresponding to the ramp 1901 abuts against the vertical surface of the locking groove 20 corresponding to the inclined surface 2001, locking the position of the moving cylinder 18 and keeping the clamping block 15 in the retracted state, thereby fixing the wire rod to the rotating cylinder 10.
[0033] As the toothed belt 5 drives the rotating cylinder 10 holding the wire bar through the processing box 1, the gear 12 on the rotating cylinder 10 can engage with the rack plate 7, enabling the wire bar to rotate synchronously as it passes through the spray box 101 and the curing box 102. This allows the high-resistance paint to be evenly sprayed onto the surface of the wire bar, while improving the subsequent curing efficiency and uniformity.
[0034] Furthermore, please refer to Figure 4 , Figure 10 The processing box 1 is also provided with an unlocking component. When the toothed belt 5 drives the fixed sleeve 9 to rotate to a designated position, the unlocking component can trigger the locking component to release the clamping structure from the wire bar. The unlocking component includes an unlocking block 8 disposed on the processing box 1. The unlocking block 8 cooperates with a wedge block 11 disposed on the locking block 19, which can drive the locking block 19 to slide relative to the slide bar 21. Preferably, the wedge block 11 and the unlocking block 8 are both configured as a "right-angled trapezoidal structure", and the inclined surfaces are respectively configured as the guide inclined surface 1101 and the unlocking surface 801.
[0035] In summary, after the wire rod passes through the processing box 1, the fixed sleeve 9, which continues to move with the toothed belt 5, gradually approaches the unlocking block 8. Then, the guide slope 1101 of the wedge block 11 contacts the unlocking surface 801 of the unlocking block 8. As the toothed belt 5 continues to move, the compression of the unlocking surface 801 on the guide slope 1101 forces the wedge block 11 to move toward the inside of the fixed sleeve 9, so that the locking block 19 disengages from the locking groove 20 away from the rotating cylinder 10. Immediately afterwards, the first spring 14 releases its elastic potential energy to push the moving cylinder 18 to move the sleeve ring 17 toward the outside of the fixed sleeve 9, so that the clamping block 15 expands to release the wire rod. Combined with the push of the moving cylinder 18 on the wire rod, the wire rod disengages from the rotating cylinder 10. Subsequently, the wire rod descends under the action of gravity and rolls along the guide slope 201 provided on the receiving platform 2 into the collection frame provided on the rear side of the receiving platform 2 (not shown in the figure).
[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.

Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution.
