[0002] Metals are usually single substances or alloys composed of metallic elements. They are a type of material that has properties such as luster, ductility, and good electrical and thermal conductivity. Metals are widely used in many fields, such as construction, transportation, electronics, aerospace, medical, and energy.

[0003] In the prior art, common drying methods for drying metal surfaces include hot air drying, oven drying and air drying. The hot air drying method uses a special hot air blower to heat the air to a certain temperature and then transports the hot air to the metal surface.

[0004] During long-term use and observation, it was found that during the process of drying the metal surface, some hot air dissipated, making it difficult for the hot air to fully act on the metal surface, resulting in uneven drying of the metal surface and causing deformation or cracking of the metal.

The all-round baking of the heat radiation will accelerate the drying of the metal surface, and reduce the deformation or cracking of the metal due to uneven drying. By arranging a motor, a first gear, a base, a second gear and a reflector, the motor can be used to drive the clamping component and the reflector to rotate together. Because the reflector is made of smooth material, it can reflect the light and heat emitted by the light-emitting bulb to the metal surface to be dried that is clamped by the clamping component during rotation, further improving the heat radiation coverage of the metal surface in all directions, and reducing the poor quality and use effect of the metal due to uneven drying.

Through the first rotating block, the second rotating block and the third rotating block, when the movable seat clamps the metal to be dried, the positions of the first rotating block, the second rotating block and the third rotating block can be continuously changed to adapt to metals of different shapes. This setting can not only clamp metals with smooth surfaces and square shapes, but also adapt to metals with uneven or irregular shapes, reducing the uneven drying of the metal surface due to unstable clamping, and further reducing the deformation or cracking of the metal due to uneven drying.

[0009] Preferably, a hot air blower is provided on the outer wall of the drying box on one side; a fixing rod is fixedly connected to the output end of the hot air blower; a supporting rod is fixedly connected to the middle of the fixing rod; a rotating seat is rotatably connected to the middle of the supporting rod; a connecting rod is fixedly connected to the outer wall of the rotating seat; there are multiple connecting rods and they are evenly arranged on the outer wall of the rotating seat; a plurality of air outlet holes are opened in the middle of the connecting rod; the air outlet holes are opened obliquely downward; the fixing rod, the supporting rod and the rotating seat are hollow and interconnected; this step enables the hot air blower, the fixing rod, the supporting rod, the rotating seat, the connecting rod and the air outlet holes to be interconnected so that the hot air blower can be Hot air is injected into the hot air blower, the fixed rod, the support rod, the rotating seat and the connecting rod, so that the hot air can float outward from the air outlet. Because the air outlet is inclined downward, the connecting rod will push the rotating seat to rotate in the middle of the support rod under the push of the hot air. The rotation of the rotating seat can increase the contact area between the hot air ejected from the air outlet and the metal surface to be dried. While using thermal radiation to dry the metal surface, hot air is used to perform a secondary drying of the metal surface, thereby improving the drying efficiency of the metal surface and further reducing the deformation or cracking of the metal caused by uneven drying.

[0010] Preferably, a second spring is fixedly connected to the top of the second gear; a sponge is fixedly connected to the end of the second spring; the sponge is slidably connected to the reflector; by arranging the second spring and the sponge, the reflector can be cleaned after the drying operation on the metal surface is completed, and the smooth material of the reflector can effectively reflect the light and heat emitted by the light bulb to the metal surface to be dried clamped by the clamping component during rotation, thereby reducing the situation where the reflector cannot efficiently reflect all the light and heat emitted by the light bulb to the metal surface to be dried clamped by the clamping component due to dirt on the reflector surface.

[0011] Preferably, a groove is provided in the middle of the first gear; the grooves are multiple and evenly arranged in the middle of the first gear; a roller is provided inside the groove; the roller is rotatably connected to the first gear; the roller rotates along the bottom of the drying box; in this step, by arranging the groove and the roller, the roller can rotate together with the first gear when the first gear rotates, thereby increasing the power of the first gear when rotating in the middle of the drying box, weakening the friction resistance of the first gear when rotating in the middle of the drying box, and reducing the friction generated by the rotation of the first gear and the bottom of the drying box, thereby reducing the rotation speed of the first gear with the clamping assembly and the second gear.

By providing a motor, a first gear, a base, a second gear and a reflector, the motor can be used to drive the clamping component and the reflector to rotate together. Since the reflector is made of a smooth material, the light and heat emitted by the light bulb can be reflected to the metal surface to be dried and clamped by the clamping component during rotation, so as to further improve the heat radiation coverage rate of the metal surface in all directions, and reduce the poor quality and use effect of the metal caused by uneven drying.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Specific examples are given below.

[0026] like Figures 1 to 5As shown, a metal surface treatment drying device described in an embodiment of the utility model includes a drying box 1; a motor 11 is provided at the bottom of the outer wall of the drying box 1; a first gear 12 is fixedly connected to the output end of the motor 11; a base 13 is fixedly connected to the top of the first gear 12; a second gear 14 is rotatably connected to the bottom of the inner wall of the drying box 1; there are multiple second gears 14 and they are meshed with the first gear 12 and arranged at the bottom of the drying box 1; a reflector 15 is fixedly connected to the top of the second gear 14; the reflector 15 is made of smooth material; a lamp holder 16 is fixedly connected to the inside of the drying box 1; there are multiple lamp holders 16 and they are evenly arranged on the inner wall of the drying box 1; the side wall of the lamp holder 16 is rotatably connected to a light-emitting bulb 17; the light bulbs 17 are multiple and evenly arranged on the side wall of the lamp holder 16; the base 13 is provided with a clamping assembly at the top; when working, the staff puts the metal to be dried in the clamping assembly, and then turns on the motor 11. The output end of the motor 11 is fixedly connected to the first gear 12, so the motor 11 will drive the first gear 12 to rotate after it is started. The top of the first gear 12 is fixedly connected to the base 13, so the rotation of the first gear 12 will drive the base 13 to rotate. At this time, the rotation of the base 13 will drive the clamping assembly arranged on the top of the base 13 to rotate synchronously, because the first gear 12 is meshed with the second gear 14. When the first gear 12 rotates, the second gear 14 will be The first gear 12 drives the rotation, so that the reflector 15 fixed to the top of the second gear 14 starts to rotate with the rotation of the second gear 14. In the process of drying the metal, the light bulb 17 emits light on the outer wall of the lamp holder 16, and the light bulb 17 continuously emits heat radiation into the drying box 1. At the same time, the heat radiation will be reflected by the reflector 15 to the metal surface to be dried clamped by the clamping component. In this step, the lamp holder 16 and the light bulb 17 are set. The light bulb 17 continuously emits heat radiation into the drying box 1. The heat radiation will act on the metal surface to be dried clamped by the clamping component, and the lamp holder 16 and the light bulb 17 are set at various inner walls of the drying box 1. The omni-directional baking of heat radiation can accelerate the drying of the metal surface and reduce the deformation or cracking of the metal caused by uneven drying. By setting the motor 11, the first gear 12, the base 13, the second gear 14 and the reflector 15, the motor 11 can drive the clamping assembly and the reflector 15 to rotate together. Since the reflector 15 is made of smooth material, the light and heat emitted by the light bulb 17 can be reflected to the metal surface to be dried by the clamping assembly during rotation, thereby further improving the heat radiation coverage of the metal surface in all directions and reducing the poor quality and use effect of the metal caused by uneven drying.

[0027] Further, such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the clamping assembly includes a vertical plate 2; the vertical plates 2 are a pair and symmetrically fixed to the top of the base 13; a plurality of first springs 21 are fixed to the middle of the inner wall of the vertical plate 2; a movable seat 22 is fixed to the other end of the first spring 21; a plurality of first rotating blocks 23 are rotatably connected to the middle of the movable seat 22; a plurality of second rotating blocks 24 are rotatably connected to the middle of the first rotating block 23; a plurality of third rotating blocks 25 are rotatably connected to the middle of the second rotating block 24; during operation, the staff places the metal to be dried between the pair of vertical plates 2, changes the telescopic length of the first spring 21, so that the metal to be dried is clamped between the movable seats 22, the first rotating block 23 in the middle of the movable seat 22 will rotate and change direction during the extrusion process, and the second rotating block 24 in the middle of the first rotating block 23 will also rotate and change direction during the extrusion process, and the third rotating block 25 in the middle of the second rotating block 24 will also rotate and change direction during the extrusion process, so that the metal to be dried is tightly clamped, and then the staff turns on the motor 11, and the motor 11 drives the first gear When the wheel 12 rotates, the rotation of the first gear 12 will drive the base 13 to rotate. At this time, the rotation of the base 13 will drive the clamping assembly set on the top of the base 13 to rotate synchronously. In this step, the vertical plate 2, the first spring 21 and the movable seat 22 are set. The metal to be dried can be fixed between a pair of movable seats 22 through the elasticity of the first spring 21 without falling. At the same time, the fixed position can be adjusted according to metals of different sizes. It is not only for drying metals of a single size, but also for increasing the flexibility of drying the metal surface. Through the first rotating block 23, the second rotating block 24 and the third rotating block 25, when the metal to be dried is clamped by the movable seat 22, the positions of the first rotating block 23, the second rotating block 24 and the third rotating block 25 can be continuously changed to adapt to metals of different shapes. This setting can not only clamp metals with smooth surfaces and square shapes, but also can adapt to metals with uneven or irregular shapes, reducing the uneven drying of the metal surface due to unstable clamping, and further reducing the deformation or cracking of the metal due to uneven drying.

[0028] Further, such as Figure 5The hot air blower 3 is provided on the outer wall of the drying box 1 on one side; the output end of the hot air blower 3 is fixedly connected to a fixing rod 31; the middle part of the fixing rod 31 is fixedly connected to a supporting rod 32; the middle part of the supporting rod 32 is rotatably connected to a rotating seat 33; the outer wall of the rotating seat 33 is fixedly connected to a connecting rod 34; the connecting rod 34 is multiple and evenly arranged on the outer wall of the rotating seat 33; a plurality of air outlet holes 35 are opened in the middle of the connecting rod 34; the air outlet holes 35 are inclined downward openings; the fixing rod 31, the supporting rod 32 and the rotating seat 33 are hollow and interconnected; when working, the staff turns on the hot air blower 3, the hot air blower 3 will continuously inject hot air into the fixing rod 31 and the supporting rod 32, the hot air in the supporting rod 32 will be injected into the rotating seat 33, and at this time, the hot air in the rotating seat 33 will flow to the connecting rod 34 and drift to the inside of the drying box 1 through the air outlet holes 35, because the air outlet holes 35 are inclined downward openings The hot air is then blown away by the hot air blower 33, and the hot air is then blown away by the hot air blower 33.

[0029] Further, such as Figures 1 to 4 As shown, a second spring 4 is fixedly connected to the top of the second gear 14; a sponge 41 is fixedly connected to the end of the second spring 4; the sponge 41 is slidably connected to the reflector 15; during operation, the staff turns off the motor 11, and after completing the drying process on the metal surface, the second spring 4 fixedly connected between the top of the second gear 14 and the bottom of the sponge 41 is pulled toward the top of the drying box 1. At this time, under the pulling force of the second spring 4, the second spring 4 will move the sponge 41 toward the bottom of the reflector 15. In this step, by arranging the second spring 4 and the sponge 41, the reflector 15 can be cleaned after the drying process on the metal surface is completed. The smooth material of the reflector 15 can effectively reflect the light and heat emitted by the light bulb 17 to the metal surface to be dried by the clamping assembly during rotation, thereby reducing the situation in which the reflector 15 cannot efficiently reflect all the light and heat emitted by the light bulb 17 to the metal surface to be dried by the clamping assembly due to dirt on the surface of the reflector 15.

[0030] Further, such as Figures 1 to 4 As shown, a groove 5 is provided in the middle of the first gear 12; there are multiple grooves 5 and they are evenly arranged in the middle of the first gear 12; a roller 51 is provided inside the groove 5; the roller 51 is rotatably connected to the first gear 12; the roller 51 rotates along the bottom of the drying box 1; during operation, the staff turns on the motor 11, and the first gear 12 fixed to the output end of the motor 11 starts to rotate. When the first gear 12 rotates, it will drive the multiple rollers 51 inside the first gear 12 to rotate synchronously. In this step, by setting the groove 5 and the roller 51, the roller 51 can rotate together with the first gear 12 when the first gear 12 rotates, thereby increasing the power of the first gear 12 when it rotates in the middle of the drying box 1, weakening the friction resistance of the first gear 12 when it rotates in the middle of the drying box 1, and reducing the friction generated by the rotation of the first gear 12 and the bottom of the drying box 1 when the first gear 12 rotates, so that the rotation speed of the first gear 12 with the clamping assembly and the second gear 14 decreases.

[0031] Further, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a sponge pad 6 is fixedly connected to the side wall of the third rotating block 25; the sponge pad 6 is made of elastic material; by setting the sponge pad 6 in this step, when the third rotating block 25 fixes the metal to be dried by rotating, the wear caused by the contact friction between the third rotating block 25 and the metal surface to be dried can be reduced, thereby reducing the impact on the quality and service life of the metal to be dried.

[0032] Working principle: The staff puts the metal to be dried in the clamping assembly, and then turns on the motor 11. The output end of the motor 11 is fixedly connected to the first gear 12. Therefore, after the motor 11 is started, it will drive the first gear 12 to rotate. The top of the first gear 12 is fixedly connected to the base 13. Therefore, the rotation of the first gear 12 will drive the base 13 to rotate. At this time, the rotation of the base 13 will drive the clamping assembly set on the top of the base 13 to rotate synchronously. Because the first gear 12 is meshed with the second gear 14, when the first gear 12 rotates, the second gear 14 will be driven to rotate by the first gear 12, so that the reflector 15 fixed on the top of the second gear 14 begins to rotate with the second gear 14. The gear 14 rotates with the rotation of the gear 14. In the process of drying the metal, the light bulb 17 emits light on the outer wall of the lamp holder 16. The light bulb 17 continuously emits heat radiation into the drying box 1. At the same time, the heat radiation will be reflected by the reflector 15 to the surface of the metal to be dried clamped by the clamping component. The staff places the metal to be dried between a pair of vertical plates 2 and changes the telescopic length of the first spring 21 so that the metal to be dried is clamped between the movable seats 22. The first rotating block 23 in the middle of the movable seat 22 will rotate and change direction during the extrusion process. At the same time, the second rotating block 24 in the middle of the first rotating block 23 will also rotate and change direction during the extrusion process. The third rotating block 25 in the middle of the second rotating block 24 will also rotate and change direction during the extrusion process, so that the metal to be dried is tightly clamped. Then the staff turns on the motor 11, and the motor 11 drives the first gear 12 to rotate. The rotation of the first gear 12 will drive the base 13 to rotate. At this time, the rotation of the base 13 will drive the clamping assembly set on the top of the base 13 to rotate synchronously. The staff turns on the hot air blower 3, and the hot air blower 3 will continuously inject hot air into the fixed rod 31 and the support rod 32. The hot air in the support rod 32 will be injected into the rotating seat 33. At this time, the hot air in the rotating seat 33 will flow to the connecting rod 34 and pass through the air outlet 35 to The air inside the drying box 1 is dispersed, because the air outlet 35 is opened obliquely downward, the connecting rod 34 will push the rotating seat 33 to rotate in the middle of the supporting rod 32 under the push of hot air, and the staff will turn off the motor 11. After completing the drying treatment of the metal surface, the second spring 4 fixed between the top of the second gear 14 and the bottom of the sponge 41 is pulled toward the top of the drying box 1. At this time, under the pulling force of the second spring 4, the second spring 4 will move the sponge 41 to the bottom of the reflector 15, and the staff will turn on the motor 11. The first gear 12 fixed to the output end of the motor 11 starts to rotate, and when the first gear 12 rotates, it will drive multiple rollers 51 inside the first gear 12 to rotate synchronously.
