[0045] Reference Figures 1 to 3According to the coating and drying equipment of the embodiment of the utility model, the coating and drying equipment includes a frame 10, an oven 20, a drying device 30 and a cleaning device 40. The oven 20 is arranged on the frame 10, and the oven 20 has a cavity 21. A plurality of conveying rollers 22 are arranged in the cavity 21. The conveying rollers 22 are arranged horizontally in sequence along the first horizontal direction of the oven 20. The axes of the conveying rollers 22 extend horizontally along the second horizontal direction of the oven 20. The first horizontal direction and the second horizontal direction are perpendicular to each other. The film material 1 is fed into from one end of the oven 20, and is fed out from the other end of the oven 20 after being transported by the conveying rollers 22. The drying device 30 is arranged in the cavity 21 of the oven 20 and is located on one side of the conveying rollers 22. The drying device 30 is used to dry the coating on the film material 1. The cleaning device 40 is arranged in the oven The cleaning device 40 is disposed in the cavity 21 of the oven 20 and above the conveying roller 22. The cleaning device 40 includes more than two spray pipes 41 with adjustable positions and a moving mechanism 42. The moving mechanism 42 is disposed in the cavity 21 of the oven 20 and located at the end of the conveying roller 22. The moving mechanism 42 is connected to one end of the spray pipe 41 and is externally connected to a water storage tank. The water storage tank stores cleaning liquid. The more than two spray pipes 41 are respectively located between two adjacent conveying rollers 22. The extension direction of the spray pipe 41 is parallel to the extension direction of the conveying roller 22. The spray pipe 41 is used to spray the conveying roller 22 on the side. The moving mechanism 42 is used to adjust the position of the spray pipe 41.

[0046] Specifically, the coating and drying equipment provided by the embodiment of the utility model mainly includes a frame 10, an oven 20, a drying device 30 and a cleaning device 40. The frame 10 is a supporting structure of the entire equipment and is firmly placed on the ground to ensure the stability and safety of the equipment. The frame 10 is made of high-strength metal material to withstand the weight of the oven 20, the drying device 30 and the cleaning device 40 and various forces generated during the working process. The oven 20 is arranged on the frame 10, and in its cavity 21, a plurality of conveying rollers 22 are arranged horizontally in sequence along the first horizontal direction of the oven 20 (the front and rear direction shown in the figure). The axes of these conveying rollers 22 extend along the second horizontal direction of the oven 20 (the left and right direction shown in the figure, the horizontal direction perpendicular to the first horizontal direction). When the equipment dries the film material 1, the film material 1 is fed in from one end of the oven 20, and is continuously conveyed by the conveying rollers 22 and sent out from the other end of the oven 20. This design enables the film material 1 to move smoothly and continuously in the oven 20, which is convenient for subsequent drying and cleaning operations. The drying device 30 is disposed in the cavity 21 of the oven 20 and is located on one side of the conveying roller 22. The drying device 30 may use an electric heating element, an infrared heater or other suitable heating elements to generate sufficient heat to dry the coating on the film material 1. The position and power of the drying device 30 are adjustable to accommodate different types and thicknesses of film materials 1 and different coatings. The drying device 30 can effectively remove moisture and solvents in the coating, thereby improving the quality and durability of the film material 1.

[0047] It should be noted that the cleaning device 40 is arranged in the cavity 21 of the oven 20 and is located above the conveying roller 22. The cleaning device 40 includes more than two spray pipes 41 with adjustable positions and a moving mechanism 42. One end of the spray pipe 41 is connected to the moving mechanism 42, and the other end is externally connected to a water storage tank. The water storage tank stores a cleaning liquid, which can be water, a cleaning agent or other suitable cleaning media. More than two spray pipes 41 are respectively located between two adjacent conveying rollers 22, and the extension direction of the spray pipe 41 is parallel to the extension direction of the conveying roller 22. A plurality of nozzles 412 are provided on the spray pipe 41, which are used to spray cleaning liquid to the conveying roller 22 on the side to clean the paint, impurities and other pollutants attached to the surface of the conveying roller 22. When the spray pipe 41 is performing the spraying operation, the conveying roller 22 can also be made to idle, which can be more conducive to the all-round cleaning of the conveying roller 22.

[0048] More specifically, the moving mechanism 42 in the cleaning device 40 is arranged in the cavity 21 of the oven 20 and is located at the end of the conveying roller 22. The moving mechanism 42 can be an electric push rod, a cylinder, a screw nut mechanism or other suitable driving mechanism, which is used to adjust the position of the spray pipe 41. Driven by the moving mechanism 42, the spray pipe 41 can move along the first horizontal direction in the cavity 21 of the oven 20 to adapt to the conveying rollers 22 at different positions. The spray pipe 41 can move between two adjacent conveying rollers 22, and the cleaning liquid is sprayed through the spray pipe 41 to remove the residual paint on the conveying roller 22, thereby preventing the residual paint from affecting the appearance of the next film material 1, thereby ensuring the coating quality of the film material 1; and the cleaning liquid is discharged from the oven 20.

[0049] The utility model realizes efficient drying of the film material 1 and rapid cleaning of the conveying roller 22 by the synergistic effect of the drying device 30 and the cleaning device 40 respectively. During the drying process, the heat generated by the drying device 30 can quickly remove the moisture and solvent in the coating; and during the cleaning process, the pollutants attached to the surface of the conveying roller 22 can be thoroughly cleaned by spraying the cleaning liquid to the conveying roller 22 through the spray pipe 41. This design not only improves the production efficiency but also ensures the quality and cleanliness of the film material 1. In addition, the utility model also has the advantages of compact structure, simple operation and convenient maintenance, which provides strong technical support for the production and processing of the film material 1. It should also be noted that after the cleaning device 40 cleans the conveying roller 22, the drying device 30 can be used to remove the moisture in the oven 20, and after drying, it can be used for drying of coating.

[0050] Refer to the figure Figures 2 to 3In some embodiments of the present invention, the moving mechanism 42 is disposed at both ends of the spray pipe 41 and is respectively connected to both ends of the spray pipe 41, and the moving mechanism 42 is used to intermittently move the position of the spray pipe 41. The moving mechanism 42 is not only connected to one end of the spray pipe 41, but is disposed at both ends of the spray pipe 41 and is respectively connected to both ends of the spray pipe 41, thereby providing stronger stability and control force, ensuring the accuracy and stability of the spray pipe 41 during the translation process.

[0051] It is understandable that the main function of the moving mechanism 42 is to intermittently move the position of the spray pipe 41 along the first horizontal direction. This intermittent movement can be performed regularly, according to a preset program, or can be triggered manually or automatically according to actual needs. The purpose of the intermittent movement is to ensure that the spray pipe 41 can evenly and comprehensively clean each conveying roller 22, and avoid dirt accumulation in certain areas due to long-term non-cleaning.

[0052] Specifically, the moving mechanism 42 can realize intermittent movement through a driving device such as an electric motor, a servo system or a stepper motor. The driving device is connected to the control system and can move the spray pipe 41 according to a preset displacement, speed and frequency. For example, the spray pipe 41 can be set to move a fixed distance each time, then stop for a period of time for cleaning, and then continue to move, and so on. In addition, in order to ensure the accuracy and stability of the movement of the spray pipe 41, the moving mechanism 42 can also be equipped with a high-precision sensor and feedback system. These sensors can monitor the position and state of the spray pipe 41 in real time and feed this information back to the control system. The control system adjusts the output of the driving device according to the feedback information, thereby realizing accurate control of the position of the spray pipe 41. Through this design, the utility model can not only ensure that each conveying roller 22 can be cleaned evenly and comprehensively, but also improve the cleaning efficiency and effect, extend the service life of the conveying roller 22, and thus improve the performance and reliability of the entire coating and drying equipment. At the same time, since the moving mechanism 42 is connected to both ends of the spray pipe 41, it can also effectively reduce the shaking and deviation that may occur in the spray pipe 41 during the movement, and further improve the accuracy and consistency of cleaning.

[0053] Further, in some embodiments of the present invention, referring to Figure 3 ,to Figure 6 The moving mechanism 42 includes a driving component 421 and a guiding component 422. The output end of the driving component 421 is connected to the guiding component 422. The guiding component 422 is connected to the end of the spray pipe 41. The driving component 421 drives the guiding component 422 to drive the spray pipe 41 to move between the conveying rollers 22.

[0054] Specifically, the moving mechanism 42 includes a driving component 421 and a guiding component 422, which work together to achieve the precise movement of the spray pipe 41 between the conveying rollers 22. The driving component 421 is the power source of the moving mechanism 42, and is responsible for providing power for the movement of the spray pipe 41. The main function of the guiding component 422 is to guide the spray pipe 41 to move along a predetermined trajectory. The driving component 421 and the guiding component 422 need to work together to achieve the precise movement of the spray pipe 41. When the control system issues a moving instruction, the driving component 421 will start and output power, and transmit the power to the guiding component 422. Under the action of power, the guiding component 422 drives the spray pipe 41 to move along the guide rail 4224, thereby realizing the function of intermittent translation. The driving component 421 and the guiding component 422 realize the precise and smooth movement of the spray pipe 41 between the conveying rollers 22, thereby improving the cleaning effect and efficiency. At the same time, this design also has the advantages of simple structure, convenient maintenance, and low cost, and provides strong technical support for the practical application of coating and drying equipment.

[0055] More specifically, refer to Figures 3 to 6 In some embodiments of the present utility model, the driving assembly 421 includes a driving member 4211, a second connecting rod 4213 and a third connecting rod 4215. The driving member 4211 is arranged on the oven 20, and the output end of the driving member 4211 is connected to one end of the first connecting rod 4212, and the driving member 4211 drives the first connecting rod 4212 to rotate; one end of the second connecting rod 4213 is rotatably connected to the other end of the first connecting rod 4212, and the first end of the second connecting rod 4213 is connected to the other end of the second connecting rod 4213 through a bending portion 4214, and the first connecting rod 4212 drives the second connecting rod 4213 to move, and the bending portion 4214 is connected to the guide assembly 422; one end of the third connecting rod 4215 is rotatably connected to the other end of the second connecting rod 4213, and the other end of the third connecting rod 4215 is rotatably connected to the oven 20, and the second connecting rod 4213 drives the third connecting rod 4215 to rotate.

[0056] The driving member 4211 is the core part of the driving assembly 421, which is responsible for providing power to drive the movement of the entire mechanism. The driving member 4211 can be an electric motor, a pneumatic motor or other types of drivers, which can be selected according to actual needs. In this embodiment, an electric motor is used as an example for explanation. The electric motor is arranged on the oven 20, and its output end is connected to one end of the first connecting rod 4212. When the electric motor is started, its output end will drive the first connecting rod 4212 to rotate. When the electric motor drives the first connecting rod 4212 to rotate, the other end of the first connecting rod 4212 will drive the second connecting rod 4213 to move accordingly. One end of the second connecting rod 4213 is connected to the other end of the first connecting rod 4212 through a rotating connecting member (such as a bearing, a hinge, etc.), so that the second connecting rod 4213 can move under the drive of the first connecting rod 4212. The first end of the second connecting rod 4213 (i.e., the end connected to the first connecting rod 4212) is connected to the other end of the second connecting rod 4213 through a bending portion 4214. The design of the bending portion 4214 enables the second connecting rod 4213 to change its direction during the movement, thereby realizing a more complex motion trajectory, and the bending portion 4214 is connected to the guide assembly 422, which can drive the guide assembly 422 to realize the corresponding motion trajectory. When the first connecting rod 4212 drives the second connecting rod 4213 to move, due to the existence of the bending portion 4214, the other end of the second connecting rod 4213 will move in a specific way. This movement mode can be precisely controlled by adjusting the angle and length of the bending portion 4214. One end of the third connecting rod 4215 is rotatably connected to the other end of the second connecting rod 4213, and the other end of the third connecting rod 4215 is rotatably connected to the oven 20. When the second connecting rod 4213 moves under the drive of the first connecting rod 4212, it drives the third connecting rod 4215 to rotate accordingly. The function of the third connecting rod 4215 is to convert the movement of the second connecting rod 4213 into a linear movement of the spray pipe 41 or other required forms of movement. Therefore, by adjusting the length of the third connecting rod 4215 and the position of the rotation connection point, the movement trajectory of the second connecting rod 4213 and thus the movement trajectory of the spray pipe 41 can be accurately controlled.

[0057] Further, in some embodiments of the present invention, referring to Figures 3 to 6 The guide assembly 422 includes a top rod 4221, a fourth connecting rod 4222 is provided at the lower end of the top rod 4221, the lower end of the fourth connecting rod 4222 is rotatably connected to the bending portion 4214, the movable second connecting rod 4213 drives the fourth connecting rod 4222 to translate in a vertical plane, and a clamping portion 4223 is provided at the upper end of the top rod 4221, the clamping portion 4223 can clamp one end of the spray pipe 41, and the translational top rod 4221 adjusts the position of the spray pipe 41.

[0058] The top rod 4221 is the main component of the guide assembly 422, and its function is to directly support and guide the spray pipe 41. The lower end of the top rod 4221 is provided with a fourth connecting rod 4222, and the upper end is provided with a clamping portion 4223. The clamping portion 4223 is capable of clamping one end of the spray pipe 41, thereby ensuring that the spray pipe 41 can move with the movement of the top rod 4221. The clamping portion 4223 takes into account the shape and size of the spray pipe 41 to ensure a stable connection and accurate guidance. Therefore, the clamping portion 4223 may include a protrusion that matches the end of the spray pipe 41, which can clamp and fix the spray pipe 41, while allowing the spray pipe 41 to be easily engaged and disengaged when necessary.

[0059] The fourth connecting rod 4222 is connected between the lower end of the top rod 4221 and the bent portion 4214 of the second connecting rod 4213 of the driving assembly 421. The lower end of the fourth connecting rod 4222 is connected to the bent portion 4214 of the second connecting rod 4213 through a rotating connecting member (such as a bearing or a hinge). This connection mode allows the fourth connecting rod 4222 to perform translational motion in a vertical plane under the drive of the second connecting rod 4213. When the second connecting rod 4213 of the driving assembly 421 moves, it drives the fourth connecting rod 4222 to translate through the bent portion 4214. Since the fourth connecting rod 4222 is rigidly connected to the top rod 4221, the translational motion of the fourth connecting rod 4222 will be directly transmitted to the top rod 4221, thereby driving the top rod 4221 (and the spray pipe 41 clamped thereon) to translate.

[0060] When the driving assembly 421 is started, it drives the fourth connecting rod 4222 to perform translational motion in a vertical plane through the coordinated action of the first connecting rod 4212, the second connecting rod 4213 and the third connecting rod 4215. This translational motion is transmitted to the spray pipe 41 through the top rod 4221, thereby adjusting the position of the spray pipe 41, and then causing the spray pipe 41 to change its position between the conveying rollers 22 to meet the sequential cleaning requirements of different conveying rollers 22. At the same time, since the entire guide assembly 422 has a simple structure and a rigid connection, it can provide stable support and guidance, ensuring the stability and accuracy of the spray pipe 41 during the movement.

[0061] Reference Figure 4 as well as Figures 6 to 8In some embodiments of the present utility model, the guide assembly 422 further includes a guide rail 4224, which is arranged on the inner wall of the oven 20 and between the inner wall of the oven 20 and the top rod 4221. The guide rail 4224 includes a first guide groove 4224a and a plurality of second guide grooves 4224b. The first guide groove 4224a is arranged horizontally along the first horizontal direction, and one end of the spray pipe 41 is accommodated in the first guide groove 4224a; the plurality of second guide grooves 4224b are arranged vertically in sequence along the first horizontal direction, and the second guide groove 4224b is located between two adjacent conveying rollers 22, and one end of the second guide groove 4224b is connected to the first guide groove 4224a, and one end of the spray pipe 41 is slidably arranged in the first guide groove 4224a and the second guide groove 4224b in an adjustable position.

[0062] The guide assembly 422 not only includes a top rod 4221 and a fourth connecting rod 4222, but also adds a guide rail 4224 structure to provide a more accurate and stable guide for the movement of the spray pipe 41. The guide rail 4224 structure is designed on the inner wall of the oven 20 and is located between the inner wall of the oven 20 and the top rod 4221. This layout not only saves space, but also ensures the stability and accuracy of the spray pipe 41 during movement. The first guide groove 4224a is arranged horizontally along the first horizontal direction (i.e., the main movement direction of the spray pipe 41). One end of the spray pipe 41 is accommodated in this guide groove and can slide freely therein, ensuring the stability and accuracy of the spray pipe 41 during horizontal movement, and effectively preventing the spray pipe 41 from deflecting and shaking. The guide rail 4224 also includes a plurality of second guide grooves 4224b. These second guide grooves 4224b are arranged in sequence along the first horizontal direction and are arranged vertically. Each second guide groove 4224b is located between two adjacent conveying rollers 22, ensuring that the spray pipe 41 can accurately move to the position between each pair of conveying rollers 22, so as to perform effective cleaning. One end of the second guide groove 4224b is connected to the first guide groove 4224a, forming a continuous sliding path. Therefore, it can be understood that under the drive of the driving component 421, one end of the spray pipe 41 can slide in the first guide groove 4224a, smoothly transition from the first guide groove 4224a to the second guide groove 4224b, or return from the second guide groove 4224b to the first guide groove 4224a.

[0063] When the two or more spray pipes 41 complete the initial cleaning, the driving assembly 421 drives the spray pipe 41 to rise from the second guide groove 4224b into the first guide groove 4224a, and the spray pipe 41 is lifted; the driving assembly 421 continues to drive the spray pipe 41 to move forward in the first guide groove 4224a, and when it moves to the next second guide groove 4224b, the specific movement mode of the driving assembly 421 can lower the spray pipe 41 in the second guide groove 4224b close to the conveying rollers 22 on both sides. More than two spray pipes 41 can achieve the effect of repeated cleaning. During the initial cleaning process, the dry paint can absorb water and dissolve, which is more conducive to the subsequent cleaning of the spray pipe 41. By analogy, the spray pipe 41 can be moved once in each rotation cycle of the driving component 421. When the upper end of the top rod 4221 does not lift one end of the spray pipe 41, the spray pipe 41 is located at the lower end of the second guide groove 4224b, and this is the stage of cleaning the conveying roller 22; and when the upper end of the top rod 4221 lifts the spray pipe 41 to the first guide groove 4224a, the top rod 4221 translates forward and backward under the action of the fourth connecting rod 4222, and the clamping portion 4223 of the top rod 4221 can drive the spray pipe 41 to translate forward and backward in the first guide groove 4224a.

[0064] Through the design of the guide rail 4224, the coating and drying equipment of the present invention realizes the precise and smooth movement of the spray pipe 41 between the conveying rollers 22. This not only improves the cleaning effect and efficiency, but also prolongs the service life of the conveying rollers 22. At the same time, the simplicity and stability of the structure of the guide rail 4224 also reduce the maintenance cost and failure rate of the equipment.

[0065] Furthermore, in some embodiments of the present invention, two groups of drive components 421 are provided, and the two groups of drive components 421 are connected by a connecting rod 423, and the two ends of the connecting rod 423 are respectively rotatably connected to one end of the first connecting rod 4212 of the two groups of drive components 421.

[0066] Specifically, the moving mechanism 42 adopts two groups of drive components 421, and the two groups of drive components 421 can work synchronously to jointly drive and guide the spray pipe 41 to move, which can improve the stability and accuracy of the movement of the spray pipe 41. When the first connecting rod 4212 of one group of drive components 421 rotates, the first connecting rod 4212 of the other group of drive components 421 will be driven to rotate synchronously through the connection of the connecting rod 423. In this way, the two groups of drive components 421 can maintain a consistent state of motion, thereby ensuring the smooth movement of the spray pipe 41. At the same time, when one group of drive components 421 is subject to external interference or load changes, the other group of drive components 421 can provide additional support and balance through the connecting rod 423, thereby reducing the deviation and shaking of the spray pipe 41. In addition, the dual drive component 421 design can also increase the driving force, so that the spray pipe 41 can respond to control instructions more quickly and move accurately to the predetermined position.

[0067] Reference Figures 5 to 8 In some embodiments of the utility model, two water inlet pipes 411 are provided in the spray pipe 41, and the water inlet pipes 411 are respectively connected to the water tank through the water inlets at both ends, and the two water inlet pipes 411 are horizontally arranged, and the two water inlet pipes 411 are connected to a plurality of nozzles 412, and the nozzles 412 are arranged along the second horizontal direction, and the plurality of nozzles 412 on the two water inlet pipes 411 are alternately arranged along the second horizontal direction.

[0068] Specifically, two water inlet pipes 411 are arranged in the spray pipe 41 of the coating and drying equipment. The two water inlet pipes 411 are arranged horizontally and connected to the water storage tank through the water inlets at both ends. The two water inlet pipes 411 arranged in the spray pipe 41 not only increase the flow of water flow, but also optimize the cleaning effect through a specific layout. The two water inlet pipes 411 are arranged horizontally to ensure the uniform distribution of water flow, and also make the entire spray system more compact and efficient. At the same time, the front and rear conveyor rollers 22 can also be cleaned at the same time.

[0069] It should also be noted that the two water inlet pipes 411 are connected to a plurality of nozzles 412, which are arranged in an array along the second horizontal direction. In particular, the nozzles 412 on the two water inlet pipes 411 are arranged alternately and spaced apart along the second horizontal direction. This layout achieves a wider cleaning coverage area, ensuring that each area can be effectively cleaned. The alternating spacing of the nozzles 412 avoids direct impact of water flow, reduces the waste of water resources, and also makes cleaning more uniform and efficient.

[0070] Further, refer to Figure 5According to some embodiments of the utility model, when the spray pipe 41 is at the lowest position, the spray pipe 41 overlaps with the projection of the conveyor roller 22 in the first horizontal direction, and the nozzle 412 sprays the cleaning liquid obliquely downward in the direction of the conveyor roller 22. When the spray pipe 41 moves to the lowest position, it overlaps with the projection of the conveyor roller 22 in the first horizontal direction. This means that the spray pipe 41 is precisely positioned to a height similar to that of the conveyor roller 22, ensuring that the cleaning liquid can be directly sprayed onto the surface of the conveyor roller 22. The nozzle 412 sprays the cleaning liquid obliquely downward in the direction of the conveyor roller 22, and the cleaning liquid can be sprayed onto the surface of the conveyor roller 22 at a certain angle, thereby better penetrating and cleaning the stains and residues on the conveyor roller 22.

[0071] In some embodiments of the utility model, the conveying roller 22 is a hot water roller, one end of which is connected to a water storage tank, and the other end of which is connected to an external hot water source. As a hot water roller, the conveying roller 22 is provided with a flow channel inside, allowing hot water to flow therein. Access to an external hot water source not only provides a heating function for the film material 1, but also helps to improve the drying efficiency. The surface temperature of the hot water roller can be adjusted by controlling the temperature and flow rate of the hot water to meet the drying requirements of different film materials 1. One end of the hot water roller is connected to a water storage tank. The water storage tank can be used to store external hot water, which can be used for cleaning the conveying roller 22 for recycling, reducing the waste of water resources; at the same time, the hot water with a higher temperature is also convenient for quickly dissolving dirt such as paint on the conveying roller 22.

[0072] Reference Figure 1 to Figure 2 In some embodiments of the present invention, the drying device 30 includes a heating component 31 and an air-driving component 32. The heating component 31 is arranged on the upper side of the cavity 21, and the heating component 31 is arranged along the first horizontal direction. The heating component 31 is used to heat the air in the cavity 21; the air-driving component 32 is arranged on the box body of the oven 20 and located above the heating component 31. The air-driving component 32 is used to blow the air heated by the heating component 31 into the cavity 21.

[0073] The heating assembly 31 is arranged on the upper side of the cavity 21 and arranged along the first horizontal direction (i.e., the conveying direction of the film material 1). The main function of the heating assembly 31 is to heat the air in the cavity 21 to provide sufficient heat to dry the film material 1. The heating assembly 31 can adopt a variety of heating methods, such as electric heating, steam heating or gas heating, etc. The specific selection of which heating method can be based on actual conditions and cost considerations. The design of the heating assembly 31 should ensure that it can heat the air in the cavity 21 evenly and quickly to improve the drying efficiency and drying quality.

[0074] The air-driving assembly 32 is arranged on the box body of the oven 20 and is located above the heating assembly 31. The main function of the air-driving assembly 32 is to blow the air heated by the heating assembly 31 into the cavity 21 to ensure that the hot air can evenly contact the film material 1, thereby achieving a fast and uniform drying effect. The air-driving assembly 32 may include components such as a fan, an air duct, and a wind direction adjusting device. The fan is used to generate a forced air flow, the air duct is used to guide the direction of the air flow, and the wind direction adjusting device is used to adjust the angle and intensity of the air flow to ensure that the hot air can evenly blow to the film material 1.

[0075] Reference Figure 1 to Figure 2 In some embodiments of the present invention, the coating and drying equipment further includes an exhaust device 50, the exhaust device 50 includes an exhaust fan 51 and an exhaust duct 52, the exhaust duct 52 is connected to the water storage tank, and the hot air in the exhaust duct 52 exchanges heat with the water in the water storage tank. The exhaust device 50 can be arranged at any place on the outer peripheral side of the oven 20, for example, it can be arranged at the upper end of the oven 20, and can also be arranged at the inlet and outlet ends in the first horizontal direction of the oven 20. In this embodiment, the position of the exhaust device 50 is not specifically limited, and it can meet the requirement of extracting the hot air with high humidity in the oven 20 through the exhaust device 50. The exhaust fan 51 extracts the hot air inside the drying device 30 to maintain the air circulation inside the oven 20 and ensure that the hot and humid air generated during the drying process can be discharged in time. The exhaust fan 51 can adjust the speed according to actual needs, thereby controlling the exhaust volume to achieve the best drying effect. The exhaust duct 52 is connected to the exhaust fan 51 and is responsible for guiding the extracted hot air to the water storage tank. In the exhaust air duct 52, the hot air exchanges heat with the water in the water tank, so that the heat of the hot air can be used to preheat the water in the water tank, thereby improving energy utilization efficiency.
