Description

Technical Field

[0001] The utility model relates to the technical field of water-based paint drying, in particular to quick-drying equipment for water-based paint. Background Art

[0002] The utility model patent with Chinese patent number CN201821248124.1 discloses a rapid drying device for water-based paint materials after spraying. The device uses a heating wire to dry the water-based paint. However, the heating wire is externally heated and dried, and the water-based paint extends from the outside to the inside during drying. As a result, there will be a significant temperature gradient between the surface and bottom layers of the water-based paint during the drying process, causing the surface moisture to dry quickly and the bottom moisture to dry slowly. At this time, the water-based paint will shrink and patina will occur, and the film-forming quality will be poor.

[0003] To this end, those skilled in the art have developed microwave drying, such as a water-based paint microwave drying device disclosed in the utility model of Chinese patent number CN202122177310.9, which uses a microwave power module to generate microwave energy. After the water-based paint absorbs the microwave energy, the microwave energy is converted into heat energy, and its own temperature is increased, and finally drying is achieved. The microwave drying speed is fast, and the surface and inner layers of the water-based paint are heated evenly, and there is no temperature gradient. However, the microwave has strong penetration, and the workpiece will also absorb microwave energy and heat it. However, when the workpiece is a poor heat conductor such as wood, it is difficult to cool after heating, and it is also prone to deformation or even cracking, which affects the service life of the finished product. In addition, the energy consumption of microwave drying is very high.

[0004] Therefore, further improvement is necessary. Utility Model Content

[0047] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0048] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0049] See also Figure 1-Figure 22 The quick-drying equipment for water-based paint includes a drying tunnel, which includes a leveling tunnel A, a water-lifting tunnel B, a quick-drying tunnel C, and a deep drying tunnel D.

[0050] The leveling tunnel A is used to gradually shrink the water-based paint on the workpiece surface to the minimum area under the action of tension before it dries and forms a film. The leveling tunnel A consists of a leveling conveyor device A1 and a leveling box A2 with a fixed cover on the leveling conveyor device A1.

[0051] The water-lifting tunnel B heats the water-based paint bottom layer by heating and causes the water in the water-based paint bottom layer to migrate toward the surface. The water-lifting tunnel B consists of a water-lifting conveying device B1 and a water-lifting box B2 fixedly mounted on the water-lifting conveying device B1.

[0052] The quick-drying tunnel C uses a heating method to heat the surface and bottom layers of the water-based paint and quickly evaporate the water content of the water-based paint. The quick-drying tunnel C consists of a quick-drying conveying device C1 and a quick-drying box C2 fixedly mounted on the quick-drying conveying device C1.

[0053] The deep drying tunnel D uses a heating method to reheat the water-based paint bottom layer and evaporate the moisture in the water-based paint bottom layer again. The deep drying tunnel D consists of a deep drying conveying device D1 and a deep drying box D2 fixedly covered on the deep drying conveying device D1.

[0054] This embodiment utilizes the cooperation between the box body and the conveying device to form a leveling tunnel A, a water-lifting tunnel B, a quick-drying tunnel C, and a deep-drying tunnel D.

[0055] During drying, the leveling tunnel A is used to evaporate the volatile gases of the water-based paint on the surface of the workpiece, while allowing the water-based paint to shrink and flatten. Then, the water-lifting tunnel B is used to heat the bottom layer of the water-based paint to migrate toward the surface, so that the bottom layer of the water-based paint is dried first relative to the surface layer. Then, the quick-drying tunnel C is used to heat the surface and bottom layers of the water-based paint to quickly evaporate the water. Finally, the deep drying tunnel D is used to heat the surface layer of the water-based paint to evaporate again, thereby ultimately achieving rapid drying of the water-based paint.

[0056] The entire drying process of water-based paint is completed gradually from the bottom layer to the surface layer, which can effectively avoid the shrinkage and patina phenomenon caused by the surface layer being completely dry but the bottom layer not being dried successfully during the drying process of the water-based paint, thereby improving the drying and film-forming quality of the water-based paint.

[0057] In addition, this quick-drying equipment has low energy consumption for drying water-based paint, which is beneficial to reducing production costs. Moreover, the workpiece will not generate high temperature during drying, thereby effectively avoiding deformation or even cracking of the workpiece due to high temperature, thereby effectively ensuring the service life of the finished product.

[0058] The leveling conveying device A1, the water-lifting conveying device B1, the quick-drying conveying device C1, and the deep-drying conveying device D1 are belt conveyors, plate chain conveyors, chain conveyors, or roller conveyors, and are separately arranged or integrally formed in sequence end to end. The leveling box A2, the water-lifting box B2, the quick-drying box C2, and the deep-drying box D2 are separately arranged or integrally formed in sequence end to end.

[0059] The workpiece passes through the leveling conveying device A1, water lifting conveying device B1, quick drying conveying device C1, and deep drying conveying device D1 and enters the leveling tunnel A, water lifting tunnel B, quick drying tunnel C, and deep drying tunnel D in sequence, and completes leveling, water lifting, quick drying, and deep drying in sequence.

[0060] In this embodiment, the leveling tunnel A, the water lifting tunnel B, the quick-drying tunnel C, and the deep drying tunnel D are independently arranged and connected end to end with each other. The corresponding leveling conveying device A1, the water lifting conveying device B1, the quick-drying conveying device C1, the deep drying conveying device D1, and the leveling box A2, the water lifting box B2, the quick-drying box C2, and the deep drying box D2 are also independently arranged and connected end to end with each other.

[0061] Each independent tunnel in the leveling tunnel A, water lifting tunnel B, quick drying tunnel C, and deep drying tunnel D is 2-10 meters long, and the temperature inside each independent tunnel is below 80 degrees.

[0062] In order to ensure that the water-based paint on the surface of the workpiece can be effectively dried while ensuring the drying quality of the water-based paint, the preferred lengths of the leveling tunnel A, water-lifting tunnel B, quick-drying tunnel C, and deep drying tunnel D in this embodiment are 6 meters respectively, and the temperature inside each tunnel is below 60 degrees. Since the drying temperature in the leveling tunnel A, water-lifting tunnel B, quick-drying tunnel C, and deep drying tunnel D is controlled below 60 degrees, the risk of deformation of the workpiece due to high temperature can be reduced, so that it is suitable for drying water-based paint on the surfaces of workpieces with different densities, thereby increasing the scope of use.

[0063] The leveling conveying device A1, the water-lifting conveying device B1, the quick-drying conveying device C1, and the deep-drying conveying device D1 all include a conveying bracket 1, on which a conveying drive motor 2 is fixedly provided, and a transmission chain 3 is driven and connected to the conveying drive motor 2. Rotating parts 4 are respectively rotatably provided at the front and rear ends of the conveying bracket 1, and the transmission chain 3 is transmission-connected to one of the rotating parts 4. A conveying belt 5 or a conveying chain 6 is wound around the front and rear rotating parts 4. The conveying bracket 1 is provided with an upper belt support plate 7 and a lower belt roller 8 corresponding to the conveying belt 5, a conveying material supporting rod 9 is provided on the conveying chain 6, and the conveying bracket 1 is provided with an upper chain support plate 10 corresponding to the conveying chain 6.

[0064] Specifically, the structure of the leveling conveying device A1 and the deep drying conveying device D1 are the same. Figure 4 、 Figure 5As shown, both include a conveying bracket 1, a conveying drive motor 2 fixedly mounted on the conveying bracket 1 and driven by a transmission chain 3, and rotating parts 4 are rotatably mounted at the front and rear ends of the conveying bracket 1. The front and rear rotating parts 4 are smooth rollers, and one of them is fixedly mounted with a gear and meshes with the transmission chain 3 through the gear. A conveying belt 5 is wound around the front and rear rotating parts 4. When working, the conveying drive motor 2 drives the transmission chain 3 to rotate, and the gear rotates while driving the rotating part 4 to rotate and the conveying belt 5 to rotate, thereby conveying the workpiece placed on the conveying belt 5. In order to provide better support for the workpiece, the conveying bracket 1 is provided with an upper belt support plate 7 and a lower belt roller 8 corresponding to the conveying belt 5. The upper belt support plate 7 supports the bottom of the conveying belt 5 rotating above, and the lower belt roller 8 supports the bottom of the conveying belt 5 rotating below, so as to avoid the conveying belt 5 from being deformed due to the placement of the workpiece, thereby improving the conveying stability of the workpiece.

[0065] The water lifting and conveying device B1 and the quick-drying conveying device C1 have the same structure. Figure 6 、 Figure 7 As shown, both include a conveying bracket 1, a conveying drive motor 2 fixedly mounted on the conveying bracket 1 and driven by a transmission chain 3, a rotating member 4 rotatably mounted at the front and rear ends of the conveying bracket 1, the front and rear rotating members 4 being smooth rollers, one of which being fixedly mounted with a gear and meshing with the transmission chain 3 through the gear, transmission gears being respectively provided on both sides of the front and rear rotating members 4, and respectively meshing with a conveying chain 6 through the transmission gear transmission, and a conveying support rod 9 being connected between the symmetrical conveying chains 6 on both sides. When the conveying drive motor 2 is working, it drives the transmission chain 3 to rotate, and the gear drives the rotating member 4 to rotate while rotating. When the rotating member 4 rotates, it drives the conveying chain 6 to rotate through the transmission gear, thereby driving the conveying support rod 9 to move, thereby conveying the workpiece placed on the conveying support rod 9. In order to provide better support for the workpiece, the conveying bracket 1 is provided with a chain upper support plate 10 corresponding to the conveying chain 6. The chain upper support plate 10 supports the bottom of the conveying chain 6 rotating above to avoid deformation of the conveying chain 6 and the chain upper support plate 10 due to the placement of the workpiece, thereby improving the conveying stability of the workpiece.

[0066] In this embodiment, the conveying bracket 1 is provided with a transmission chain protection shell 35 corresponding to the transmission chain 3, and the transmission chain protection shell 35 is covered on the outside of the transmission chain 3. The conveying bracket 1 is provided with a conveying belt protection shell 36 corresponding to the conveying belt 5, and the conveying belt protection shell 36 is covered on the outside of the conveying belt 5. The conveying bracket 1 is provided with a conveying chain protection shell 37 corresponding to the conveying chain 6, and the conveying chain protection shell 37 is covered on the outside of the conveying chain 6, thereby effectively protecting the transmission chain 3, the conveying belt 5, and the conveying chain 6. At the same time, the conveying belt protection shell 36 will also block the outside of the belt upper support plate 7 and the belt lower roller 8, and the conveying chain protection shell 37 will also block the outside of the chain upper support plate 10.

[0067] In order to ensure smooth transportation of the workpiece, the front and rear ends of the water-lifting and conveying device B1 and the quick-drying and conveying device C1 are respectively provided with feed rollers 39 and discharge rollers 40 for rotation, so that the workpiece can stably enter and exit the water-lifting tunnel B and the quick-drying tunnel C through the feed rollers 39 and discharge rollers 40.

[0068] Leveling tunnel A includes normal temperature leveling, heated leveling, or humidified leveling. The heating methods of water pumping tunnel B, quick drying tunnel C, and deep drying tunnel D include radiation heating, conduction heating, or convection heating.

[0069] Among them, the leveling time is 1-10 minutes, and the leveling time of this embodiment is preferably 4-8 minutes. Thereby, the volatile gas of the water-based paint moistening the surface of the workpiece is evaporated within a certain period of time, and the wet water-based paint is also shrunk and flattened to prevent the water-based paint from having pores during subsequent drying, thereby ensuring the flatness and glossiness of the water-based paint surface. In addition, when the workpiece is sprayed, leveling also plays a role in partially drying the surface of the water-based paint.

[0070] In normal temperature leveling, the leveling tunnel A is at normal temperature, and the workpiece is leveled at normal temperature in the leveling tunnel A.

[0071] In heated leveling, a heating element is installed in the leveling tunnel A. The heating element can be a heating wire, a heating tube 38, or a heating film. When the heating element is in operation, it heats the temperature in the leveling tunnel A. The workpiece is leveled in the heated leveling tunnel A. Among them, heated leveling is used when the ambient temperature is low in order to shorten the leveling time.

[0072] In humidified leveling, an atomizer is installed in the leveling tunnel A. When the atomizer is working, it humidifies the inside of the leveling tunnel A, and the workpiece is leveled in the humidified leveling tunnel A. Among them, humidified leveling is used when the ambient humidity is low to prevent the surface of the water-based paint from drying out during leveling.

[0073] A water-lifting far-infrared lamp 11 is provided in the water-lifting box B2. The water-lifting far-infrared lamp 11 is located above the water-lifting and conveying device B1, and the wave peaks generated during operation avoid 1.6-2 microns and 3.2-3.6 microns. A quick-drying far-infrared lamp 12 is provided in the quick-drying box C2. The quick-drying far-infrared lamp 12 is located above the quick-drying and conveying device C1, and the peak of the main wave generated during operation is 3.2-3.6 microns. A deep-drying far-infrared lamp 13 is provided in the deep-drying box D2. The deep-drying far-infrared lamp 13 is located above the deep-drying and conveying device D1, and the wave peak generated during operation is 1.6-2 microns.

[0074] Specifically, the wave peaks generated by the water-lifting far-infrared lamp 11 during operation avoid 1.8 microns and 3.4 microns, so that the wavelength of the main wave generated by the water-lifting far-infrared lamp 11 is longer, the corresponding penetrating power is higher, and the temperature generated is lower, so that the infrared energy absorbed by the water in the bottom layer of the water-based paint is more than the infrared energy absorbed by the water on its surface, so that the water in the bottom layer of the water-based paint is heated, and at this time the water in the bottom layer of the water-based paint migrates upward and is dried.

[0075] The peak of the main wave generated by the quick-drying far-infrared lamp 12 during operation is 3.4 microns. The water molecules on the surface and bottom layers of the water-based paint absorb the infrared radiation of this wave. At this time, the entire water-based paint is heated to quickly dry the moisture on the surface and bottom layers of the water-based paint, thereby improving efficiency.

[0076] The peak wave generated by the deep drying far-infrared lamp 13 during operation is 1.8 microns, which makes the wavelength of the main wave generated by the deep drying far-infrared lamp 13 shorter, the corresponding penetrating power is lower, and the temperature generated is higher, so that the infrared energy absorbed by the surface moisture of the water-based paint is more than the infrared energy absorbed by the bottom moisture. At this time, the surface moisture of the water-based paint is heated, so that the surface moisture of the water-based paint is deeply dried.

[0077] The leveling box A2, water-lifting box B2, quick-drying box C2, and deep-drying box D2 are all composed of front and rear end panels 14, left and right side panels 15, and a top panel 16 that are spliced ​​together.

[0079] In this embodiment, a plurality of heating tubes 38 , water-lifting far-infrared lamps 11 , quick-drying far-infrared lamps 12 , and deep-drying far-infrared lamps 13 are respectively provided and spaced apart along the front and rear end plates 14 .

[0080] In addition, the leveling box A2, the water-lifting box B2, the quick-drying box C2, and the deep-drying box D2 also have a certain heat preservation function, which can respectively insulate the energy generated by the heating tube 38, the water-lifting far-infrared lamp 11, the quick-drying far-infrared lamp 12, and the deep-drying far-infrared lamp 13, so that the temperature in the leveling tunnel A, the water-lifting tunnel B, the quick-drying tunnel C, and the deep-drying tunnel D is controlled below 60 degrees.

[0081] Front and rear reflectors 19 are provided on the front and rear end panels 14 , left and right reflectors 20 are provided on the left and right side panels 15 , and a top reflector 21 is provided on the top panel 16 .

[0082] The water-lifting far-infrared lamp 11 , the quick-drying far-infrared lamp 12 , and the deep-drying far-infrared lamp 13 are respectively located between the front and rear reflectors 19 , the left and right reflectors 20 , and the top reflector 21 .

[0083] The water-lifting far-infrared lamp 11, the quick-drying far-infrared lamp 12, and the deep-drying far-infrared lamp 13 respectively reflect light through the front and rear reflectors 19, the left and right reflectors 20, and the top reflector 21, so that any area inside the water-lifting tunnel B, the quick-drying tunnel C, and the deep-drying tunnel D can be irradiated by infrared energy, ensuring that the water-based paint at any position on the workpiece can achieve a uniform drying effect.

[0084] In addition, the heating tube 38 is also located between the front and rear reflectors 19 , the left and right reflectors 20 , and the top reflector 21 , and can also achieve heat reflection through the front and rear reflectors 19 , the left and right reflectors 20 , and the top reflector 21 .

[0085] Transparent windows 22 or movable doors 23 are provided on the front and rear end panels 14, the left and right side panels 15 or the top panel 16. The movable doors 23 can be opened and closed by sliding or hinged.

In addition, a transparent window 22 is also provided on the movable door 23, so that the user can observe the drying condition of the water-based paint without opening the movable door 23.

[0087] Tunnel air vents 24 are provided on the front and rear end panels 14 , the left and right side panels 15 or the top panel 16 , and an air supply component E or a circulating air exhaust component F is provided on the tunnel air vents 24 .

[0088] Specifically, air supply components E are respectively provided on the top plates 16 of the water lifting tunnel B and the quick drying tunnel C. The air supply components E include a fan air guide seat 25, an air supply volute fan 26, and an air guide plate 27. The fan air guide seat 25 has a fixed cover arranged on the tunnel air outlet 24. The air supply volute fan 26 is fixedly arranged on the fan air guide seat 25, and its air outlet is connected with the tunnel air outlet 24 through the fan air guide seat 25. The air guide plate 27 is straight and is arranged on the tunnel air outlet 24 at an angle along the direction of workpiece transportation.

[0089] When working, the air supply volute fan 26 draws external air into the fan air guide seat 25, and the external air is then introduced into the tunnel air outlet 24 through the fan air guide seat 25, and is guided along the direction of workpiece transportation through the air guide plate 27, thereby accelerating the air flow speed on the surface of the water-based paint and improving the drying efficiency and quality of the water-based paint. Since the guidance direction of the external air is the same as the direction of workpiece transportation, it will not affect the transportation of the workpiece.

[0090] A circulating exhaust assembly F is provided on the top plate 16 of the deep drying tunnel D. The circulating exhaust assembly F includes a fan air guide housing 28, a circulating connecting pipe 29, a circulating volute fan 30, a first diffuser plate 31, and a second diffuser plate 32. The fan air guide housing 28 is fixedly covered on the first diffuser plate 31 and fixed on the tunnel air outlet 24. The circulating volute fan 30 is fixedly arranged on the fan air guide housing 28, and its air outlet is connected to the tunnel air outlet 24 through the fan air guide housing 28. The second diffuser plate 32 is umbrella-shaped and fixedly arranged in the fan air guide housing 28. A plurality of diffusion holes 33 are evenly distributed on the first diffuser plate 31 and the second diffuser plate 32, respectively. Circulating openings 34 are provided on the front and rear end panels 14, the left and right side panels 15 or the top plate 16. One end of the circulating connecting pipe 29 is connected to the circulating opening 34, and the other end is connected to the air outlet of the circulating volute fan 30.

[0091] When working, the circulating volute fan 30 extracts the air in the deep drying tunnel D through the cooperation of the circulation opening 34 and the circulation connecting pipe 29. The extracted air enters the fan air guide housing 28 and is diffused by the first diffuser plate 31 and the second diffuser plate 32 and enters the deep drying tunnel D again through the tunnel air outlet 24, thereby realizing the air circulation flow inside the deep drying tunnel D, which is beneficial to the drying of water-based paint. In addition, since the first diffuser plate 31 and the second diffuser plate 32 are provided with a plurality of diffusion holes 33, and the first diffuser plate 31 is a straight plate and is arranged below the umbrella-shaped second diffuser plate 32, and the cross-section of the fan air guide housing 28 is also umbrella-shaped, the second diffuser plate 32 and the inner wall of the fan air guide housing 28 form a diffusion gap, so that the air can enter the deep drying tunnel D in a diffused manner and can flow to any position inside the deep drying tunnel D, thereby accelerating the air flow speed of the surface layer of the water-based paint and improving the deep drying efficiency and quality of the water-based paint.

[0092] In this embodiment, three circulating exhaust assemblies F are provided on the deep drying tunnel D, and the three circulating exhaust assemblies F are arranged on the top plate 16 at intervals along the workpiece conveying direction. Among them, the front and rear two circulating exhaust assemblies F are arranged on the same axis, and the middle circulating exhaust assembly F is staggered with the front and rear two circulating exhaust assemblies F. This not only improves the air circulation flow inside the deep drying tunnel D, but also avoids the problem that the air cannot flow to every corner inside the deep drying tunnel D due to flowing in the same direction at the same time. In addition, the air circulation exhaust directions of the front and rear two circulating exhaust assemblies F are the same, and the air circulation exhaust direction of the middle circulating exhaust assembly F is opposite to the air circulation exhaust direction of the front and rear two circulating exhaust assemblies F, thereby further improving the air circulation flow stability and range.

[0093] The quick-drying method of this quick-drying equipment is as follows:

[0094] Step 1: spraying water-based paint onto the surface of the workpiece;

[0095] Step 2: Leveling: Place the workpiece on the leveling conveyor A1 and transport it into the leveling tunnel A. Before the water-based paint on the workpiece surface dries and forms a film, the tension of the surface paint gradually shrinks it to the smallest area.

[0096] Step 3: Water lifting. The leveling conveyor A1 transports the workpiece to the water lifting conveyor B1. The workpiece is transported by the water lifting conveyor B1 into the water lifting tunnel B. The water lifting tunnel B uses a heating method to heat the bottom layer of the water-based paint, causing the water in the bottom layer of the water-based paint to migrate toward its surface.

[0097] Step 4: Rapid drying: The water-lifting conveying device B1 conveys the workpiece to the quick-drying conveying device C1. The workpiece is conveyed by the quick-drying conveying device C1 into the quick-drying tunnel C. The quick-drying tunnel C uses a heating method to heat the surface and bottom layers of the water-based paint, causing the water in the entire water-based paint to evaporate quickly.

[0098] Step 5: Deep drying. The quick drying conveying device C1 conveys the workpiece to the deep drying conveying device D1. The workpiece is conveyed into the deep drying tunnel D by the deep drying conveying device D1. The deep drying tunnel D adopts a heating method to reheat the surface of the water-based paint to evaporate the moisture on the surface of the water-based paint again.

[0099] Step 6: The deep drying conveying device D1 conveys the dried workpieces out of the deep drying tunnel D, and the user then collects the dried workpieces.
