Description

Technical Field

[0001] This application relates to the field of spray painting technology, and in particular to a spray painting apparatus for producing spring steel wire. Background Technology

[0002] A painting system is an industrial device used in the manufacturing of metal wires, primarily for the continuous and uniform coating of spring steel wires. For spring steel wires, the core technology lies in continuous spraying and instant curing under constant tension control. This allows liquid paint to quickly form a uniform, dense, and firmly adhered film on the high-speed moving wire surface, providing crucial process assurance for rust prevention, corrosion protection, marking, and special surface treatment of the steel wire.

[0003] The prior art publication CN223288274U provides a steel structure omnidirectional painting device for reducing paint waste. The pressurized pumping device includes a connecting rod fixedly connected to the side wall of one of the enclosure shells. One end of the connecting rod is fixedly connected to a paint storage bottle. A delivery pump is fixedly connected to the upper side of the connecting rod. The output end of the delivery pump is connected to the inside of the paint storage bottle via a suction pipe. An output pipe is fixedly connected to the output end of the delivery pump. Four spray hoses are fixedly connected to the side wall of the output pipe, with one end of each of the four spray hoses connected to four nozzles. A hand handle is fixedly connected to the bottom side wall of the connecting rod. When the delivery pump is started, it can input paint from the paint storage bottle into the output pipe through the suction pipe, and then the paint flows along the four spray hoses into the four nozzles and is sprayed out from the nozzles.

[0004] However, in this prior art, the positions of the four nozzles on the side wall of the output pipe are fixed, and the paint sprayed from the nozzles is affected by the atomization characteristics, resulting in differences in the amount of paint sprayed on the surface of the steel wire, which leads to uneven paint spraying on the surface of the steel wire and poor anti-corrosion effect of the steel wire. Utility Model Content

[0005] To improve the problem of uneven paint spraying on the surface of steel wire, this application provides a painting device for producing spring steel wire.

[0006] The painting apparatus for producing spring steel wire provided in this application adopts the following technical solution: A painting device for producing spring steel wire includes a spray head, a swing mechanism, and a swing frame. The steel wire is threaded through the swing frame. The number of spray heads is N, where N is an integer greater than or equal to 2. The spray heads are arranged uniformly along the circumference of the steel wire and are used to spray paint onto the surface of the steel wire. The swing frame is rotatably mounted on a frame and connected to the swing mechanism. The swing mechanism drives the spray heads to swing along a direction perpendicular to the steel wire conveying direction. The radius of the steel wire is r, and the lateral width of the spray head on the surface of the steel wire is L, where L satisfies the relationship L≥2rsin(360° / 2N).

[0007] By adopting the above technical solution, multiple nozzles are simultaneously oscillated under the drive of an oscillating device. By setting the relationship between the steel wire radius, the number of nozzles, and the horizontal width of the spray, it is ensured that the nozzles can spray paint onto the steel wire surface without dead angles. Compared with the prior art, this application adopts a solution of multiple nozzles oscillating to spray paint onto the steel wire surface, which enables the paint to be evenly sprayed onto the steel wire surface through the nozzles, thereby improving the anti-corrosion effect of the steel wire.

[0008] Preferably, the swing frame is a round tube open at both ends, so as to create a painting environment within the swing frame.

[0009] By adopting the above technical solution, and using a circular tube structure with openings at both ends for the swing frame, a painting environment is created inside the swing frame, ensuring a clean work site.

[0010] Preferably, the inner wall of the swing frame is provided with a Teflon coating.

[0011] By adopting the above technical solution, a Teflon coating is applied to the inner wall of the swing frame to prevent paint from adhering to the swing frame and to facilitate the cleaning of waste paint inside the swing frame.

[0012] Preferably, the entrance of the swing frame is provided with a rubber sheet, which is circular and has a wire hole in the middle for the steel wire to pass through. The wire hole is adapted to the steel wire, and the rubber sheet is used to wipe away debris from the surface of the steel wire.

[0013] By adopting the above technical solution, the steel wire holes in the rubber sheet can be used to wipe away debris from the surface of the steel wire, so that the paint can better cover the surface of the steel wire and improve the anti-corrosion effect of the steel wire.

[0014] Preferably, the swing mechanism includes a first drive rod, a swing element, and a swing shaft. A first motor is provided on the frame. The output shaft of the first motor is fixedly connected to the first drive rod. The first drive rod is connected to the swing shaft through the swing element, so that the first motor can drive the swing shaft to swing. The swing shaft is connected to the swing frame through a connector.

[0015] By adopting the above technical solution, the rotation of the first drive rod is converted into the reciprocating swing of the swing shaft through the swing component. The swing shaft drives the swing frame to swing through the connecting component, so that the first motor can drive the swing shaft to swing, thereby improving the convenience of swinging the swing frame.

[0016] Preferably, the swinging component includes a swing rod, which is rotatably connected to the first drive rod. The swing shaft has a sliding groove for the swing rod to slide into, the sliding groove passing through the axis of the swing shaft. The swing rod is slidably disposed within the swing shaft so as to drive the swing shaft to swing.

[0017] By adopting the above technical solution, the rotation of the first drive rod is converted into the swing of the swing shaft by the cooperation of the swing rod and the sliding groove, so that the swing rod drives the swing shaft to swing, thereby improving the convenience of the swing mechanism.

[0018] Preferably, the connecting member includes a first bevel gear and a second bevel gear. The first bevel gear is coaxially and fixedly connected to the swing frame, and the second bevel gear is coaxially and fixedly connected to the swing shaft. The first bevel gear and the second bevel gear are meshed together.

[0019] By adopting the above technical solution, the first bevel gear is coaxially fixedly connected to the swing frame, the second bevel gear is coaxially fixedly connected to the swing shaft, and the first bevel gear and the second bevel gear are meshed together, so that the first motor can drive the swing frame to swing through the first bevel gear and the second bevel gear, thereby improving the accuracy of the swing mechanism transmission.

[0020] Preferably, the frame is provided with a paint conveying mechanism, which is connected to the spray head through a paint pipe so as to convey paint into the spray head.

[0021] By adopting the above technical solution, paint is sprayed onto the steel wire through the paint conveying mechanism, so that the nozzle can continuously spray paint onto the steel wire.

[0022] Preferably, the frame is rotatably provided with a support wheel and a pressure wheel, and a steel wire passes through and abuts against the support wheel and the pressure wheel. The frame is provided with a second motor, which is connected to at least one of the support wheel and the pressure wheel to drive the steel wire to move.

[0023] By adopting the above technical solution, the support wheel and the pressure wheel are used to press against the steel wire and drive the wire forward, so that the steel wire enters the swing frame more stably and smoothly, thereby improving the stability of steel wire painting.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Compared with the existing technology where the four nozzles on the side wall of the output pipe are fixed, this application adopts a scheme in which multiple nozzles swing and spray the surface of the steel wire, so that the paint can be evenly sprayed onto the surface of the steel wire through the nozzles, thereby improving the anti-corrosion effect of the steel wire.

[0025] 2. The rotation of the first drive rod is converted into the reciprocating swing of the swing shaft through the swing component. The swing shaft drives the swing frame to swing through the connecting component, so that the first motor can drive the swing shaft to swing, which improves the convenience of swinging the swing frame.

[0026] 3. By using the support wheel and the pressure wheel to press against the steel wire and drive the wire forward, the steel wire enters the painting device more stably and smoothly, thus improving the stability of steel wire painting. Attached Figure Description

[0035] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0036] This application discloses a painting apparatus for producing spring steel wire.

[0037] Reference Figure 1 , Figure 2 A painting apparatus for producing spring steel wire includes a spray head 2 (as shown in the attached image). Figure 5 The system comprises a swing mechanism 3 and a swing frame 4. The swing frame 4 is a circular tube open at both ends. The swing frame 4 is rotatably connected to the frame 6 via bearings and is placed horizontally to allow the steel wire 1 to pass through, thus creating a painting environment within the swing frame 4 and ensuring a clean work site. The number of nozzles 2 is N, where N is an integer greater than or equal to 2. In this embodiment, the number of N is four. All four sets of nozzles 2 are mounted on the swing frame 4 and are evenly arranged along the circumference of the steel wire 1. The nozzles of the nozzles 2 face the surface of the steel wire 1. The swing frame 4 is rotatably mounted on the frame 6 and connected to the swing mechanism 3. The swing mechanism 3 drives the nozzles 2 to swing along a direction perpendicular to the conveying direction of the steel wire 1. The radius of the steel wire 1 is r, and the lateral width of the nozzles 2 spraying the surface of the steel wire 1 is L, where L satisfies the relationship L≥2rsin(360° / 2N). In this embodiment... This allows the paint to be sprayed evenly and without dead angles onto the surface of the steel wire 1 through the spray nozzle 2, thereby improving the corrosion resistance of the steel wire 1.

[0038] Reference Figure 3 The swing mechanism 3 includes a first drive rod 32, a swing shaft 33, and a swing component 34. The swing component 34 includes a swing rod 341. A first motor 31 is provided on the frame 6. The output shaft of the first motor 31 is fixedly connected to the first drive rod 32, so that the first motor 31 can drive the first drive rod 32 to perform circular motion. The swing shaft 33 is provided with a sliding groove 331 for the swing rod 341 to slide into. The sliding groove 331 is arranged radially and passes through the axis of the swing shaft 33. One end of the swing rod 341 is hinged to the first drive rod 32, and the other end is slidably inserted into the sliding groove 331 of the swing shaft 33. The swing shaft 33 is rotatably connected to the frame 6. The first motor 31 drives the first drive rod 32 to perform circular motion and drives the swing rod 341 to slide in the sliding groove 331 of the swing shaft 33, converting the circular motion of the first drive rod 32 into the reciprocating swing of the swing shaft 33 around its axis, thereby improving the convenience of swinging the swing frame 4.

[0039] Reference Figure 4The swing shaft 33 is connected to the swing frame 4 via a connector 35. The connector 35 includes a first bevel gear 351 and a second bevel gear 352. The first bevel gear 351 is coaxially sleeved on the swing frame 4 and fixedly connected to the swing frame 4. The second bevel gear 352 is coaxially fixedly connected to the swing shaft 33. The first bevel gear 351 and the second bevel gear 352 are meshed, and the transmission ratio between the first bevel gear 351 and the second bevel gear 352 is 1, so that the first motor 31 can drive the swing frame 4 to swing through the first bevel gear 351 and the second bevel gear 352, thereby improving the accuracy of the transmission of the swing mechanism 3.

[0040] Reference Figure 5 , Figure 6 A rubber sheet 41 is installed at the inlet of the swing frame 4 and is fixedly connected to the swing frame 4. The rubber sheet 41 is annular and adapted to the opening of the swing frame 4. A wire hole 43 is opened in the middle of the rubber sheet 41 for the steel wire 1 to pass through. The wire hole 43 is adapted to the steel wire 1. When the steel wire 1 enters the swing frame 4, the steel wire 1 comes into contact with the rubber sheet 41 and friction occurs. The rubber sheet 41 wipes away the debris on the surface of the steel wire 1 so that the paint can better cover the surface of the steel wire 1, improving the anti-corrosion effect of the steel wire 1. The inner wall of the swing frame 4 is fully covered with a Teflon coating 42. When the nozzle 2 sprays the steel wire 1, it can effectively prevent the paint from adhering to the inner wall of the swing frame 4, and the accumulated waste paint can be easily removed, improving the waste cleaning efficiency.

[0041] The frame 6 is equipped with a paint conveying mechanism 5, which includes a pressure pump 52 and a paint tank 53. The nozzle 2 is connected to the paint tank 53 through a paint pipe 51. The paint pipe 51 includes a coarse paint pipe 511 and a fine paint pipe 512. There are four fine paint pipes 512 with the same parameters. Each fine paint pipe 512 corresponds to one nozzle 2. Each nozzle 2 is connected to one end of the corresponding fine paint pipe 512. The other end of each fine paint pipe 512 is inserted into the coarse paint pipe 511 and connected to the coarse paint pipe 511. The pressure pump 52 delivers the paint in the paint tank 53 to the nozzle 2 on the swing frame 4 through the coarse paint pipe 511 and the fine paint pipe 512 by pressurizing, thereby spraying the paint onto the surface of the steel wire 1, so that the nozzle 2 can continuously spray paint onto the steel wire 1.

[0042] Reference Figure 7The frame 6 is equipped with support wheels 64 and pressure wheels 65. There are three sets of support wheels 64 and two sets of pressure wheels 65. The frame 6 is also equipped with threaded rods 61, threaded sleeves 62, and support blocks 63. There are five sets of each threaded rod 61, threaded sleeve 62, and support block 63. Each support wheel 64 corresponds to one support block 63, and each pressure wheel 65 also corresponds to one support block 63. One end of each threaded rod 61 is rotatably connected to the frame 6, and the other end is threadedly connected to the threaded sleeve 62. The threaded sleeve 62 is fixedly connected to the support block 63, and the support block 63 is slidably connected to the frame 6 via a guide rail. Rotating the threaded rod 61 causes the support block 63 to rise or fall. A second motor 66 is fixedly installed on each set of support blocks 63. The output shaft of each set of second motors 66 passes through the support block 63 and is fixedly connected to the support wheel 64 or pressure wheel 65, driving the support wheel 64 or pressure wheel 65 to rotate, thereby moving the steel wire 1. Each set of support wheels 64 is located below the steel wire 1, and each set of pressure wheels 65 is located above the steel wire 1. The support wheels 64 and pressure wheels 65 allow the steel wire 1 to pass through and press against the steel wire 1. The sidewalls are provided with grooves that are compatible with the steel wire 1, so that the steel wire 1 can enter the swing frame 4 more stably and smoothly, thus improving the stability of the steel wire 1 painting.

[0043] The implementation principle of a painting device for producing spring steel wire according to an embodiment of this application is as follows: When painting the steel wire 1 inside the swing frame 4, the first motor 31 drives the first drive rod 32 to rotate, causing the swing rod 341 to slide in the sliding groove 331 of the swing shaft 33, converting the circular motion of the first drive rod 32 into the reciprocating swing of the swing shaft 33 around its axis. The swing shaft 33 drives the first bevel gear 351 and the second bevel gear 352 to rotate synchronously, so that the second bevel gear 352 drives the swing frame 4 to rotate, thereby converting the reciprocating swing of the swing shaft 33 into the reciprocating swing of the swing frame 4. The number of nozzles 2 N, the radius r of the steel wire 1, and the transverse width L of the nozzles 2 spraying the surface of the steel wire 1 satisfy the following relationship: This allows the multiple nozzles 2 arranged circumferentially on the swing frame 4 to spray paint onto the surface of the steel wire 1 without any blind spots. Combined with the swing frame 4 driving the nozzles 2 to swing back and forth, the paint is sprayed more evenly onto the surface of the steel wire 1, improving the anti-corrosion effect of the steel wire 1.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
