Description

Technical Field

[0001] This application relates to the field of paint curing, and in particular to a heating device for preheating and curing paint on steel. Background Technology

[0002] On steel pretreatment lines and container production lines, the technology of spray painting, curing and drying is increasingly being adopted on a large scale. However, in actual production, the existing spray painting, curing and drying systems simply use heat sources to bake the objects to be dried. Such devices have a large heat loss and cannot react to the objects to be dried in the most efficient way. Not only is the efficiency low, but it is also easy to cause uneven curing and drying of the paint, resulting in defects in product quality. Furthermore, it is impossible to carry out spray painting, curing and drying treatment on steel in a comprehensive manner.

[0003] Patent document CN202877086U discloses a radiant heating device for preheating, painting, and curing of steel pretreatment lines and container production lines. The device includes a radiant tube with gas-fired radiant heat wave generators at both ends and one or two ports in the middle, each connected to a vacuum pump. Directional reflectors are located on the upper and outer sides of the radiant tube, which is connected to a tube-plate hanger. End caps are located at both ends of the directional reflectors. The radiant tube is connected via a pipe connection device. The beneficial effects of this invention are: it uses radiant heat waves to directly dry and cure the paint on the steel surface, reducing heat loss in the air and fundamentally solving a series of problems associated with traditional drying devices, such as high losses, low efficiency, and serious environmental pollution. This gives it high efficiency, energy saving, comfort, economy, safety, and environmental friendliness, and overcomes the limitation of traditional technologies that cannot heat the steel surface in all directions.

[0004] However, the aforementioned steel pretreatment line and container production line preheating, painting, curing, and radiation heating devices cannot uniformly spray paint onto the steel clamps, resulting in difficulties in curing the paint and the inability to rotate and dry it after spraying. To address these issues, we propose a steel preheating, painting, curing, and heating device. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as the inability to uniformly spray paint onto steel, which makes it difficult to cure the paint and the inability to rotate and dry it after spraying. Therefore, this invention proposes a steel preheating and paint curing heating device.

[0006] The steel preheating, spraying, and curing heating device provided in this application adopts the following technical solution: A steel preheating and painting curing heating device, comprising: First box; The feed inlet is located on one side of the first housing. A through slot is provided on one side of the first housing, and a fan is fixedly connected inside the through slot; The first heating block is fixedly connected to one side of the fan; A paint spray box is fixedly connected to the top of the first box, and a spray nozzle is connected to the bottom of the paint spray box; The second housing is slidably connected to one side of the first housing; The transmission assembly is fixedly connected to one side of the second housing.

[0007] Furthermore, the transmission assembly includes a first motor fixedly connected to one side of the second housing, and the output shaft of the first motor is fixedly connected to a bidirectional threaded rod, on which two first threaded sleeves are threadedly connected.

[0008] Furthermore, a clamping plate is fixedly connected to one side of each of the two first threaded sleeves, and two rotating shafts are rotatably connected to each of the two clamping plates.

[0009] Furthermore, a rotating plate is fixedly connected to one end of each of the two rotating shafts, and a gear is fixedly connected to one end of each rotating shaft.

[0010] Furthermore, a rack meshes with the gear, and the rack is slidably connected to one side of the first housing, while a third housing is fixedly connected to one side of the first housing.

[0011] Furthermore, a second motor is fixedly connected to the top of the third housing, and a threaded rod is fixedly connected to the output shaft of the second motor.

[0012] Furthermore, a second threaded sleeve is threaded onto the threaded rod, and a drive shaft is fixedly connected to one end of the threaded rod.

[0013] Furthermore, the drive shaft is rotatably connected to the bottom inner wall of the third housing, and the inner sides of both clamping plates are fixedly connected to the second heating blocks, and the second threaded sleeve is fixedly connected to one side of the second housing.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. This solution can uniformly spray paint on the steel clamp, making it easy to cure the paint. The gear moves on the rack, causing the gear to rotate through the rack. The gear drives the rotating shaft to rotate, the rotating shaft drives the rotating plate to rotate, the rotating plate drives the steel to rotate, and the steel drives another rotating plate to rotate, so that the steel rotates. After rotating to different surfaces, the rotation stops, and then the steel is sprayed with paint. 2. This solution can rotate and dry the steel after the paint is sprayed. The air pressure blown out by the fan drives the heat generated by the first heating block, so that the air pressure carries heat and can dry the paint on the steel. At the same time, by starting the second motor, the steel can be turned over to facilitate the drying of the paint. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1 Reference Figures 1-3 A steel preheating and painting curing heating device, comprising: First box 1; Feed inlet 2 is located on one side of the first box 1; A through slot is provided on one side of the first housing 1, and a fan 3 is fixedly connected inside the through slot; The first heating block 4 is fixedly connected to one side of the fan 3; The paint spray box 5 is fixedly connected to the top of the first box 1, and the bottom of the paint spray box 5 is connected to the spray nozzle 6. The second housing 7 is slidably connected to one side of the first housing 1; The transmission assembly is fixedly connected to one side of the second housing 7.

[0019] Specifically, the transmission assembly includes a first motor 8 fixedly connected to one side of the second housing 7, and the output shaft of the first motor 8 is fixedly connected to a bidirectional threaded rod 9, on which two first threaded sleeves 10 are threadedly connected.

[0020] Specifically, each of the two first threaded sleeves 10 is fixedly connected to one side of a clamping plate 11, and each of the two clamping plates 11 is rotatably connected to two rotating shafts 12.

[0021] Specifically, a rotating plate is fixedly connected to one end of each of the two rotating shafts 12, and a gear 13 is fixedly connected to one end of each rotating shaft 12.

[0022] Specifically, a rack 14 meshes with the gear 13, and the rack 14 is slidably connected to one side of the first housing 1. A third housing 15 is fixedly connected to one side of the first housing 1.

[0023] Specifically, a second motor 16 is fixedly connected to the top of the third housing 15, and a threaded rod 17 is fixedly connected to the output shaft of the second motor 16.

[0024] Specifically, a second threaded sleeve 18 is threadedly connected to the threaded rod 17, and a drive shaft 19 is fixedly connected to one end of the threaded rod 17.

[0025] Specifically, the drive shaft 19 is rotatably connected to the bottom inner wall of the third housing 15, and the inner sides of the two clamping plates 11 are fixedly connected to the second heating blocks, and the second threaded sleeve 18 is fixedly connected to one side of the second housing 7.

[0026] The implementation principle of the steel preheating, painting, and curing heating device in this application embodiment is as follows: First, the steel is placed into the first box 1 through the feed port 2, so that the steel is located between two clamping plates 11. Then, the first motor 8 is started, which drives the bidirectional threaded rod 9 to rotate. The bidirectional threaded rod 9 drives two first threaded sleeves 10, which in turn drive the two clamping plates 11 to move. The two clamping plates 11 drive the two rotating shafts 12 to move, which in turn drive the two rotating plates to move. The two rotating plates clamp the steel. Then, the two second heating blocks are started. The two second heating blocks transfer heat to the steel through metal heat transfer, which preheats the steel. Then, the paint spraying box 5 is started, which sprays paint through the spray nozzle 6 to cover the upper surface of the steel. After the upper surface is covered, the second motor 16 is started, which drives the threaded rod 17 to rotate. The threaded rod 17 drives the transmission shaft 19 to rotate, which in turn drives the second... The threaded sleeve 18 moves, which in turn moves the second housing 7. The second housing 7 moves the two clamping plates 11, which in turn move the two rotating shafts 12. The two rotating shafts 12 move the two rotating plates, which in turn move the steel. At the same time, the rotating shafts 12 move the gear 13, which moves on the rack 14. The gear 13 rotates through the rack 14, which in turn moves the rotating shaft 12. The rotating shaft 12 rotates the rotating plate, which in turn moves the steel. The steel then moves another rotating plate, causing the steel to rotate. After rotating to different surfaces, the rotation stops. The steel is then painted. After painting multiple surfaces of the steel, the fan 3 is started, and the first heating block 4 is also started. The air pressure blown by the fan 3 carries the heat generated by the first heating block 4, allowing the air pressure to dry the paint on the steel. At the same time, the second motor 16 is started, which allows the steel to be flipped over to facilitate the drying of the paint.

When the push rod motor is started, the push rod motor drives the connecting rod to move, and the connecting rod drives the sliding plate to move, so that the sliding plate can move the steel, which facilitates the loading and unloading of the steel.

[0028] 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.
