Technical Field

[0001] This utility model relates to the field of steel plate processing technology, and in particular to a fully automatic four-axis grinding, cleaning, coating and drying integrated machine for thickness measurement. Background Technology

[0002] In steel plate processing, in addition to grinding and cleaning, coating is usually required depending on the application scenario. In existing technology, steel plate grinding and cleaning can be completed by one machine, while steel plate coating is completed by another machine. This results in the need to transport steel plates between machines using AGVs or other methods, which is inefficient. Summary of the Invention

[0003] This invention addresses the problems of existing technologies by providing a fully automatic four-axis grinding, cleaning, coating, and drying integrated machine that can sequentially grind, clean, coat, and dry steel plates, thereby improving the processing efficiency of steel plates.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

Along the transmission direction of the transmission mechanism, the machine body is further provided with a thickness measuring mechanism, a grinding unit, a cleaning unit, a coating mechanism, and a drying mechanism in sequence.

[0006] The thickness measuring mechanism is used to sense the thickness of the steel plate and adjust the distance between the grinding unit and the transmission mechanism according to the thickness of the steel plate.

[0007] The grinding mechanism is used to grind both surfaces of the steel plate separately, with each surface of the steel plate being ground twice.

[0011] Furthermore, the thickness measuring mechanism includes a thickness measuring frame and three thickness measuring modules spaced apart on the thickness measuring frame. Each thickness measuring module includes a contact roller, a thickness sensor, and a telescopic mechanism. The contact roller is vertically mounted on the thickness measuring frame via the telescopic mechanism. The thickness sensor is installed on the thickness measuring frame and is used to sense the vertical movement of the contact roller.

[0012] Furthermore, the telescopic mechanism includes a rotating frame, an elastic element, a limiting element, and a limiting sleeve. The limiting sleeve is mounted on the thickness measuring frame, and the limiting element is movably mounted on the thickness measuring frame and located inside the limiting sleeve. The limiting sleeve is used to prevent the limiting element from detaching from the rotating frame. The bottom of the limiting element passes through the bottom of the thickness measuring frame and connects to the rotating frame. The elastic element is located between the rotating frame and the thickness measuring frame. The contact roller is rotatably mounted on the rotating frame. The thickness sensor is used to sense the lifting amplitude of the rotating frame.

[0013] The top of the rotating frame is equipped with a trigger, and the thickness sensor has a probe that protrudes from the bottom of the thickness sensor and is positioned directly opposite the trigger.

[0014] Furthermore, the grinding unit includes a first lower grinding mechanism, a first upper grinding mechanism, a second lower grinding mechanism, and a second upper grinding mechanism arranged sequentially. Each of the first lower grinding mechanism, the first upper grinding mechanism, the second lower grinding mechanism, and the second upper grinding mechanism has a grinding roller and a drive module for driving the grinding roller to rotate. The height adjustment mechanism includes a drive motor, a reducer, a transmission shaft, and two lifting reducers. The drive motor drives and connects to one lifting reducer through the reducer. The transmission shaft is connected between the two lifting reducers. Each lifting reducer is driven and connected to a height adjustment seat. The height adjustment seat is provided with a bearing seat. The two ends of the grinding roller are rotatably mounted on the bearing seats of the two height adjustment modules. The linear drive component is signal-connected to the thickness measuring mechanism.

[0015] Furthermore, the drive module includes a rotary motor, a rotary belt, a swing motor, and an eccentric transmission structure. The height adjustment seat is provided with a guide rail, and the bearing seat is slidably disposed on the guide rail. The rotary motor drives one end of the grinding roller through the rotary belt, and the swing motor drives the bearing seat connected to the other end of the grinding roller through the eccentric transmission structure.

[0016] Furthermore, the drive module also includes a support base, on which the rotating motor is mounted. The support base is provided with multiple support shafts that pass through the support base. The upper and lower portions of the support shafts are respectively fitted with first springs, and at least one second spring is provided at the bottom of the support base.

[0017] Furthermore, the cleaning unit includes a water supply mechanism, an upper spray mechanism, a lower spray mechanism, and a wiping mechanism.

The water supply mechanism is used to supply water to the upper spray mechanism and the lower spray mechanism. The wiping mechanism includes two wiping rollers and a wiping drive module for driving the wiping rollers to rotate. The two wiping rollers are used to wipe the upper surface and the lower surface of the steel plate, respectively.

The upper wiping roller and the lower wiping roller are used to wipe the upper and lower surfaces of the steel plate, respectively, and the wiping drive module is used to drive the upper wiping roller and / or the lower wiping roller to rotate.

[0019] Furthermore, the coating mechanism includes an upper coating roller, a lower coating roller, a coating drive module, a collection container, and a paint spraying module. The upper coating roller and the lower coating roller are rotatably mounted on the machine body. There is a coating gap between the upper coating roller and the lower coating roller for the steel plate to pass through. The coating drive module is used to drive the upper coating roller and / or the lower coating roller to rotate. The paint spraying module is used to spray paint onto the upper coating roller and the lower coating roller. The upper coating roller and the lower coating roller are used to coat the two surfaces of the steel plate respectively. The collection container is used to collect the paint that has not adhered to the steel plate.

[0020] Furthermore, the drying mechanism includes multiple drying components arranged in sequence. Each drying component includes an upper drying pipe, a lower drying pipe, a heating module, and an air blowing module. The upper and lower drying pipes have a drying gap for the steel plate to pass through. The air blowing module is connected to the upper and lower drying pipes to form an airflow circuit. The heating module is used to heat the gas in the airflow circuit.

Detailed Implementation

[0034] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 11As shown, this utility model provides a fully automatic four-axis thickness measuring, grinding, cleaning, coating, and drying integrated machine, including a machine body 1 and a transmission mechanism 2 disposed on the machine body 1. Along the transmission direction of the transmission mechanism 2, the machine body 1 is also provided with a thickness measuring mechanism 3, a grinding unit 4, a cleaning unit 5, a coating mechanism 6, and a drying mechanism 7 in sequence.

[0036] The thickness measuring mechanism 3 is used to sense the thickness of the steel plate and adjust the distance between the grinding unit 4 and the transmission mechanism 2 according to the thickness of the steel plate.

[0037] The grinding mechanism is used to grind both surfaces of the steel plate separately, with each surface of the steel plate being ground twice.

[0038] The cleaning unit 5 is used to clean and dry the steel plate after it has been ground.

[0039] The coating unit 6 is used to coat the dried steel plate;

[0040] The drying unit 7 is used to dry the coated steel plate.

[0041] Specifically, the transmission mechanism 2 of this utility model preferably includes a transmission drive module 47 and multiple transmission rollers. The transmission drive module 47 is composed of a motor and a reducer, and uses a transmission mechanism composed of a chain and a sprocket to realize synchronous drive of multiple transmission rollers. During operation, the steel plate is transmitted by the transmission mechanism 2, and the thickness of the steel plate is sensed by the thickness measuring mechanism 3. The grinding unit 4 adjusts the distance between itself and the transmission mechanism 2 according to the thickness of the steel plate measured by the thickness measuring mechanism 3, thereby ensuring that the steel plate does not have a rigid collision with the grinding unit 4 when passing by, so that the grinding action can be carried out reliably. After grinding, the steel plate is moved to the cleaning unit 5 by the transmission mechanism 2. The cleaning unit 5 washes away the lubricant and grinding debris on the surface of the steel plate, and then wipes the steel plate dry. Then the steel plate can be coated. Finally, the drying mechanism 7 dries the steel plate to ensure the coating effect.

[0042] In this embodiment, the thickness measuring mechanism 3 includes a thickness measuring frame 31 and three thickness measuring modules 32 spaced apart on the thickness measuring frame 31. Each thickness measuring module 32 includes a contact roller 33, a thickness sensor 34, and a telescopic mechanism 35. The contact roller 33 can be raised and lowered on the thickness measuring frame 31 via the telescopic mechanism 35. The thickness sensor 34 is installed on the thickness measuring frame 31 and is used to sense the raising and lowering amplitude of the contact roller 33.

[0043] The thickness measuring mechanism 3 employs a three-point thickness measurement method to sense the thickness change of the steel plate at three locations along the transmission direction, thereby obtaining a basic understanding of the overall thickness of the steel plate. The working principle of the thickness measuring mechanism 3 is as follows: During operation, the steel plate is transmitted to the machine body 1 via the transmission mechanism 2. First, the thickness of the steel plate is measured at three locations by the thickness measuring mechanism 3. Then, the first lower grinding mechanism 41, the first upper grinding mechanism 42, the second lower grinding mechanism 43, and the second upper grinding mechanism 44 are adjusted in height by their respective height adjustment mechanisms 45, ensuring that the steel plate can pass smoothly and be ground, guaranteeing grinding safety and quality. The ground steel plate is then transported to the outside for the next step.

[0044] In this embodiment, the thickness measuring mechanism 3 includes a thickness measuring frame 31 and three thickness measuring modules 32 spaced apart on the thickness measuring frame 31. Each thickness measuring module 32 includes a contact roller 33, a thickness sensor 34, and a telescopic mechanism 35. The contact roller 33 can be raised and lowered on the thickness measuring frame 31 via the telescopic mechanism 35. The thickness sensor 34 is installed on the thickness measuring frame 31 and is used to sense the raising and lowering amplitude of the contact roller 33.

[0045] In practical applications, the length direction of the thickness measuring frame 31 is perpendicular to the transmission direction of the steel plate, and three thickness measuring modules 32 are arranged sequentially along the length direction of the thickness measuring frame 31. During steel plate transmission, the steel plate passes through the three thickness measuring modules 32, with the contact rollers 33 of each module contacting three different positions on the steel plate, continuously changing their contact positions as the steel plate is transmitted. The contact rollers 33 rise due to the impact of the steel plate, and the thickness sensor 34 measures the magnitude of this rise. Combined with preset values, the thickness of the steel plate can be calculated. This ensures that the thickness changes at the three positions along the transmission direction are measured and uploaded, guaranteeing a more accurate and reliable thickness reading for the steel plate. Furthermore, because this invention uses mechanical contact to measure the thickness of the steel plate, the measurement accuracy is not affected by airborne particles.

[0046] During the above process, when the contact roller 33 comes into contact with the steel plate, the contact roller 33 will be lifted up. However, due to factors such as inertia and gravity, the contact roller 33 is in an unstable state. Therefore, this invention will wait for a time t after the height of the contact roller 33 changes to trigger the thickness sensor 34, so as to ensure that the contact roller 33 is stable before acquiring the signal change of the thickness sensor 34, in order to ensure the accuracy of the measured information.

[0047] Preferably, the time t can be set according to the actual component parameters, typically between 0.05 and 0.3 seconds. When the contact roller 33 contacts the steel plate, the steel plate will stop for the aforementioned time t to allow the contact roller 33 to enter a steady state before continuing to move and transmit. This ensures that the contact roller 33 can measure the positions of different regions in the elongation direction of the corresponding position on the steel plate, thereby achieving the best possible acquisition of the thickness parameters of the entire steel plate through the cooperation of the three contact rollers 33.

[0048] In this embodiment, the telescopic mechanism 35 includes a rotating frame 351, an elastic element 352, a limiting element 353, and a limiting sleeve 354. The limiting sleeve 354 is installed on the thickness measuring frame 31. The limiting element 353 is movably disposed on the thickness measuring frame 31 and located inside the limiting sleeve 354. The limiting sleeve 354 is used to prevent the limiting element 353 from detaching from the rotating frame 351. The bottom of the limiting element 353 passes through the bottom of the thickness measuring frame 31 and is connected to the rotating frame 351. The elastic element 352 is disposed between the rotating frame 351 and the thickness measuring frame 31. The contact roller 33 is rotatably disposed on the rotating frame 351. The thickness sensor 34 is used to sense the lifting amplitude of the rotating frame 351.

[0049] The contact roller 33 is rotatably mounted on the rotating frame 351, allowing it to rotate as the steel plate is transferred. This reduces the friction between the contact roller 33 and the steel plate, thus minimizing wear. During this process, the elastic element 352 acts as a retaining element, ensuring the stability of the contact roller 33 through its elasticity and preventing excessive fluctuations that could affect the measurement results.

[0050] The top of the limiting member 353 is provided with an anti-detachment cap 356. The width of the anti-detachment cap 356 is larger than the inner diameter of the limiting sleeve 354, which is used to prevent the limiting member 353 from detaching from the limiting sleeve 354. Since the rotating frame 351 and the contact roller 33 move up and down synchronously, the thickness sensor 34 actually measures the lifting amplitude of the rotating frame 351, and its measurement result is more stable than that of measuring the lifting amplitude of the rotating contact roller 33.

[0051] Preferably, there are two of the limiting member 353, the limiting sleeve 354, and the elastic member 352, which can effectively ensure the stability of the thickness measuring module 32.

[0052] Specifically, the elastic element 352 includes a spring. The elastic element 352 is sleeved on one end of the limiting element 353 that protrudes from the bottom of the thickness measuring frame 31. The two ends of the elastic element 352 are respectively connected to / abut against the thickness measuring frame 31 and the rotating frame 351. That is, the elastic element 352 is directly sleeved on the limiting element 353, which can better achieve the effect of buffering and holding.

[0053] Specifically, the top of the rotating frame 351 is provided with a trigger 355, and the thickness sensor 34 has a probe 341. The probe 341 protrudes from the bottom of the thickness frame 31, and the probe 341 is positioned directly opposite the trigger 355.

[0054] The thickness sensor 34 is preferably a contact sensor, which reversely infers the thickness of the steel plate by the height to which the probe 341 is forced to rise after being touched. The trigger 355 is preferably rotatably connected to the rotating frame 351, and the trigger 355 can be replaced with one of suitable height according to the actual changes in the steel plate to be measured, without increasing the flexibility of this utility model.

[0055] In this embodiment, the thickness measuring module 32 further includes a lifting seat 36 and a limiting pin 37. The lifting seat 36 is provided with a lifting groove 361, the thickness measuring frame 31 is provided with a lifting hole, the limiting pin 37 passes through the lifting groove 361 and is installed in the lifting hole, and the thickness sensor 34 is installed on the lifting seat 36.

[0056] The thickness sensor 34 is used to contact the probe 341 and is driven to rise by the probe 341.

[0057] The thickness sensor 34 is a floating structure. When the steel plate is within a certain thickness range, the raising and lowering of the probe 341 will not affect the height change of the thickness sensor 34. However, when the thickness of a steel plate is too large and exceeds the travel of the probe 341, the entire lifting seat 36 will be lifted up. At this time, the lifting of the lifting seat 36 can effectively prevent damage to the thickness sensor 34, thus achieving the effect of floating protection for the thickness sensor 34.

[0058] Specifically, the lifting seat 36 has a limiting part 362, and a limiting post 363 is provided at the bottom of the limiting part 362. The limiting post 363 is used to abut against the thickness measuring frame 31 to prevent the lifting seat 36 from descending too much. That is, the shape of the limiting part 362 is similar to a "7" shape, and the limiting post 363 is located below the top of the "7", which has the effect of limiting the descent of the lifting seat 36. The limiting post 363 is preferably fixed to the limiting part 362 by screws or bolts, so as to facilitate the adjustment of the height of the limiting post 363 and the replacement of the limiting post 363.

[0059] Specifically, the bottom of the limiting member 353 is screwed to the rotating frame 351, and a suitable limiting member 353 can be replaced as needed.

[0060] Furthermore, the grinding unit 4 includes a first lower grinding mechanism 41, a first upper grinding mechanism 42, a second lower grinding mechanism 43, and a second upper grinding mechanism 44 arranged sequentially. The first lower grinding mechanism 41, the first upper grinding mechanism 42, the second lower grinding mechanism 43, and the second upper grinding mechanism 44 each have a grinding roller 46 and a drive module 47 for driving the grinding roller 46 to rotate. The height adjustment mechanism 45 includes a drive motor 451, a reducer 452, a transmission shaft 453, and two lifting reducers 454. The drive motor 451 drives and connects to one lifting reducer 454 through the reducer 452. The transmission shaft 453 is connected between the two lifting reducers 454. Each lifting reducer 454 is driven and connected to a height adjustment seat 455. The height adjustment seat 455 is provided with a bearing seat 456. The two ends of the grinding roller 46 are rotatably set on the bearing seats 456 of the two height adjustment modules. The linear drive component is signal-connected to the thickness measuring mechanism 3.

[0061] The height adjustment mechanism 45 is driven by a drive motor 451, which in turn drives two lifting reducers 454 to perform the same action via a reducer 452, thereby ensuring that the lifting amplitude of both ends of the grinding roller 46 is basically the same and thus guaranteeing stability.

[0062] Specifically, the drive module 47 includes a rotary motor 471, a rotary belt 472, an oscillating motor 473, and an eccentric transmission structure 474. The height adjustment seat 455 is provided with a guide rail 457, and the bearing seat 456 is slidably disposed on the guide rail 457. The rotary motor 471 drives one end of the grinding roller 46 through the rotary belt 472, and the oscillating motor 473 drives the bearing seat 456 connected to the other end of the grinding roller 46 through the eccentric transmission structure 474.

[0063] In actual use, the swing motor 473 is mounted on the bearing housing 456.

[0064] During grinding, the grinding roller 46 is rotated by the rotating belt 472 driven by the rotating motor 471, thereby achieving the grinding effect on the steel plate. To improve the grinding effect, this invention also includes a swing motor 473 and an eccentric transmission structure 474. The swing motor 473 drives the eccentric transmission mechanism to move the two bearing seats 456 back and forth along the length of the guide rail 457. This means that in addition to rotating, the grinding roller 46 also moves in a direction perpendicular to the transmission direction of the steel plate, so that the grinding roller 46 moves relative to the steel plate in more than one direction, which helps to improve the grinding effect.

[0065] The direction in which the grinding roller 46 moves back and forth is usually less than 1cm, which is enough to achieve the desired effect.

[0066] Specifically, the drive module 47 also includes a support base 475, a rotating motor 471 is mounted on the support base 475, the support base 475 is provided with multiple support shafts 476, the support shafts 476 pass through the support base 475; the portion of the support shaft 476 above the support base 475 and the portion below the support base 475 are respectively fitted with a first spring 477, and at least one second spring 478 is provided at the bottom of the support base 475.

[0067] When the bearing housing 456 is raised or lowered, the tension of the rotating belt 472 will inevitably change. Compared with the existing technology that uses a tensioning wheel for control, this utility model uses a support seat 475. The tension control of the rotating belt 472 is achieved by the cooperation of the first spring 477 and the second spring 478 of the support seat 475. Taking the height adjustment mechanism 45 driving the grinding roller 46 to rise as an example, when the grinding roller 46 rises, the rotating belt 472 will inevitably be pulled by the grinding roller 46. It is equivalent to the grinding roller 46 "pulling" the rotating motor 471 to rise through the rotating belt 472. At this time, the first spring 477 and the second spring 478 will recover their deformation to a certain extent due to the reduced pressure from the rotating motor 471. This, together with the rotating belt 472, raises the rotating motor 471 to a certain height, thus achieving the effect of keeping the tension of the rotating belt 472 from changing too much.

[0068] Specifically, the machine body 1 is also provided with a spraying mechanism 9 for spraying lubricating fluid onto the steel plate. The spraying mechanism 9 includes a liquid delivery pipe 91 and n spraying pipes 92. All n spraying pipes 92 are connected to the liquid delivery pipe 91. The liquid delivery pipe 91 is used to connect to an external liquid source. The output end of the spraying pipe 92 extends into the machine body 1. A spray head 93 is installed at the output end of the spraying pipe 92. The spray head 93 is facing the grinding shaft.

[0069] n is an integer not less than 4.

[0070] In this embodiment, n=8, that is, every two spray pipes 92 correspond to one grinding mechanism. Lubricating fluid is sprayed onto the grinding roller 46 of the grinding mechanism through the spray head 93 of the spray pipe 92, so that the friction at the contact position between the steel plate and the grinding roller 46 is reduced, thereby preventing the grinding roller 46 from wearing out too quickly.

[0071] Specifically, the spraying mechanism 9 also includes a recovery pipe 94. The bottom of the body 1 is inclined from the side to the middle. A collection port is provided in the middle of the bottom of the body 1. The recovery pipe 94 is connected to the collection port. The recovery pipe 94 is used to transfer the recovered lubricating fluid to an external liquid source.

[0072] By utilizing the funnel-like structure at the bottom of the body 1, the lubricating fluid falling at the bottom of the body 1 is guided to the collection port and then recovered through the recovery pipe 94. This not only avoids the lubricating fluid remaining in the body 1, but also realizes the recycling of the lubricating fluid.

[0073] In this embodiment, a plurality of limiting shafts 11 are provided inside the body 1, and quick-release structures 12 are provided at both ends of the limiting shafts 11. The limiting shafts 11 are connected to the body 1 through the quick-release structures 12.

[0074] The limiting shaft 11 is used to cooperate with the grinding roller 46 to "clamp" the steel plate, ensuring reliable grinding of the steel plate. The assembly of the limiting shaft 11 is achieved through the quick-release structure 12, which can be a conventional structure or an auxiliary structure. Figure 9 The disclosed structure allows workers to assemble, fix, or disassemble the limiting shaft 11 simply by pulling and rotating the quick-release structure 12, thus facilitating the replacement of the limiting shaft 11 and improving efficiency.

[0075] In this embodiment, the cleaning unit 5 includes a water supply mechanism, an upper spray mechanism 52, a lower spray mechanism 53, and a wiping mechanism 54. The upper spray mechanism 52 and the lower spray mechanism 53 are both disposed on the body 1 and are located above and below the transmission mechanism 2, respectively. The water supply mechanism is used to supply water to the upper spray mechanism 52 and the lower spray mechanism 53. The wiping mechanism 54 includes two wiping rollers and a wiping drive module for driving the wiping rollers to rotate. The two wiping rollers are used to wipe the upper surface and the lower surface of the steel plate, respectively.

[0076] The water supply mechanism preferably consists mainly of a water pump and a water tank. The water tank can be connected to an external water source. The water pump supplies water to the upper spray mechanism 52 and the lower spray mechanism 53. The two spray water on the upper and lower surfaces of the steel plate respectively, thereby washing away the lubricant and debris adhering to the steel plate. After rinsing, the wiping mechanism 54 wipes the steel plate to remove the water, residual lubricant and debris, ensuring that the surface of the steel plate is clean before entering the coating mechanism 6.

[0077] Specifically, the wiping mechanism 54 includes an upper wiping roller 541, a lower wiping roller 542, and a wiping drive module. The upper wiping roller 541 and the lower wiping roller 542 are used to wipe the upper and lower surfaces of the steel plate, respectively. The wiping drive module is used to drive the upper wiping roller 541 and / or the lower wiping roller 542 to rotate. Preferably, the wiping drive mechanism includes a motor, a reducer, and a corresponding transmission structure, which can drive at least one of the upper wiping roller 541 and the lower wiping roller 542 to rotate. The rotation direction of the two rollers can be opposite to the transmission direction of the steel plate, resulting in a better wiping effect.

[0078] In this embodiment, the coating mechanism 6 includes an upper coating roller 61, a lower coating roller 62, a coating drive module, a collection container 64, and a paint spraying module 65. Both the upper coating roller 61 and the lower coating roller 62 are rotatably mounted on the machine body 1. A coating gap exists between the upper coating roller 61 and the lower coating roller 62 to allow the steel plate to pass through. The coating drive module drives the upper coating roller 61 and / or the lower coating roller 62 to rotate. The paint spraying module 65 sprays paint onto the upper coating roller 61 and the lower coating roller 62. The upper coating roller 61 and the lower coating roller 62 respectively coat the two surfaces of the steel plate. The collection container 64 collects any paint that has not adhered to the steel plate. Preferably, the paint spraying module 65 uses a pump as its power source to spray paint onto the upper coating roller 61 and the lower coating roller 62. Then, the upper coating roller 61 and the lower coating roller 62 rotate to apply the paint to the surface of the steel plate, thus achieving the coating function. Because the spraying process may result in paint splashing and paint dripping from the steel plate after coating, a collection container 64 is installed to collect the paint. The paint is then guided to the outside for treatment through the outlet at the bottom of the collection container 64, achieving the effect of treating the paint without stopping the machine.

[0079] In this embodiment, the drying mechanism 7 includes a plurality of drying components 70 arranged in sequence. Each drying component 70 includes an upper drying pipe 71, a lower drying pipe 72, a heating module 73, and an air blowing module 74. The upper drying pipe 71 and the lower drying pipe 72 have a drying gap for the steel plate to pass through. The air blowing module 74 is connected to the upper drying pipe 71 and the lower drying pipe 72 to form an airflow circuit. The heating module 73 is used to heat the gas in the airflow circuit.

[0080] The conveying rollers of the conveying mechanism 2 can be staggered with the drying assembly 70 to ensure that the conveying process does not affect the drying. Both the upper drying pipe 71 and the lower drying pipe 72 are hollow structures. The high-temperature gas passing through them transfers heat to the outside, achieving the effect of heating the air around the drying assembly 70. By using air to dry the surface of the steel plate, the drying of the steel plate can be achieved without blowing air and affecting the coating.

[0081] It should be noted that the conveyor roller at the drying mechanism 7 is supported and conveys the steel plate by wheels at both ends, thereby minimizing the contact area with the steel plate and reducing the impact on the undried coating.
