Description

Technical Field

[0001] The present application relates to the technical field of ovens, and in particular to an oven system for use in hydrogen production carbon paper materials. Background Art

[0002] The coating machine drying oven is a device that processes the coated substrate with hot air. It can remove the excess solvent in the coating, thereby completing the curing of the coating, modification of the substrate surface or related physical and chemical reactions. In the process of using hot air drying, the ovens provided in the prior art mostly blow hot air to dry the side of the substrate with the coating. The specific process is: hot air enters from the air inlet of the oven, and then takes away the excess solvent when passing through the surface of the substrate, and the cold air with the solvent is discharged from the air outlet, and this cycle is repeated until the drying degree meets the requirements.

[0003] However, in actual applications, when the airflow inside the oven is not well controlled through the above-mentioned hot air circulation method, the substrate will fluctuate during the drying process and cause damage. Moreover, if the solvent in the coating cannot evaporate quickly, the front and back sides of the substrate will be heated unevenly, resulting in uneven solvent volatilization, which will lead to uneven curing of the coating. In severe cases, uneven heat transfer will cause local overheating or cooling of the substrate, causing uneven thermal expansion or contraction of the substrate, thereby causing deformation of the substrate and affecting the final quality of the product. Summary of the invention

[0006] By adopting the above technical scheme, with the cooperation of the upper air guide hood, the lower air guide hood, the first drainage chamber and the second drainage chamber, hot air and cold air can circulate along a specific path, so that the hot air covers the front and back sides of the carbon hydrogen paper, so that the carbon hydrogen paper can be evenly heated during the drying process, which helps to improve the drying quality and efficiency; the setting of the flattening roller group not only allows the carbon hydrogen paper to be smoothly transported in the box, but also effectively avoids wrinkles or unevenness of the material during the drying process, further improving the product yield and quality; the heating mechanism is installed on the outside of the box as an independent module, which is convenient for maintenance and replacement, while reducing the complexity of the inside of the box and the impact of temperature on electronic components.

[0008] By adopting the above technical solution, the fire baffle separates the heating source and the fan, effectively preventing high temperature from damaging sensitive components such as the fan, which can improve the safety and service life of the equipment. At the same time, with the synergistic effect of the heating source and the fan, the air in the hot air duct can be quickly and evenly heated to the required temperature and supplied to the box through the air inlet. Such operation can ensure precise temperature control during the drying process, thereby ensuring product quality. The setting of the cold air duct enables the hot air discharged from the box to be recycled to reduce energy consumption and emissions.

[0009] Preferably, a heat preservation mechanism is provided in the body, and the heat preservation mechanism is provided between the hot air duct and the cold air duct.

[0010] By adopting the above technical solution, the insulation mechanism is placed between the hot air duct and the cold air duct, which effectively reduces the loss of heat energy during the transmission process, so that the hot air can maintain a higher temperature before being transmitted to the box, thereby improving the thermal energy efficiency of the oven system. At the same time, the cold air can also be preheated when it flows back along the cold air duct, thereby reducing the energy consumed by the system to maintain the required temperature, which helps to achieve the goal of energy saving and emission reduction.

[0011] Preferably, the insulation mechanism includes an insulation box, the insulation box includes an insulation chamber, a first ventilation duct and a second ventilation duct, a blocking member is arranged between the first ventilation duct and the second ventilation duct, one end of the insulation chamber is connected to the first ventilation duct, and the other end is connected to the second ventilation duct, and the three are assembled to form a "J"-shaped ventilation corridor, and an end of the first ventilation duct away from the insulation chamber is connected to the cold air duct, and an end of the second ventilation duct away from the insulation chamber is connected to the hot air duct.

[0012] By adopting the above technical scheme, the "J"-shaped ventilation corridor connects the cold air duct with the hot air duct. At the same time, by setting up blocking parts, the direct mixing of cold and hot air is reduced, and the hot air is mixed and retained in the insulation chamber, so that the temperature of the insulation box is between the temperatures of the hot air and the cold air. On the one hand, the temperature of the hot air can be guaranteed and the waste of energy can be reduced, so that the hot air can maintain a stable temperature during the transmission process, and the impact of temperature fluctuations on the drying process can be reduced; on the other hand, the cold air can be preheated when it flows back along the cold air duct, thereby reducing the energy consumed by the system to maintain the required temperature, which is helpful to achieve the purpose of energy conservation and emission reduction. In this application, through reasonable ventilation duct design, the possibility of high-temperature gas in the hot air duct directly contacting the cold air duct is reduced, thereby reducing the risk of damage to the equipment due to thermal expansion and contraction or other reasons, and improving the safety of the equipment.

[0014] By adopting the above technical solution, the insulation pad installed on the inner wall of the insulation chamber and the inside of the barrier, as well as the first keel frame set at the corner, jointly enhance the insulation effect. Such a setting can not only reduce heat loss and improve the efficiency of thermal energy utilization, but also ensure that the temperature inside the oven is more uniform and stable.

[0015] The insulation pads installed on the inner walls of the box body and the second keel frame set at the corners further improve the thermal insulation performance, help prevent overheating of the outside of the oven, improve operational safety, and reduce the impact of ambient temperature on the internal temperature of the oven; the addition of the first keel frame and the second keel frame helps to enhance the thermal insulation stability and heat insulation stability of the entire system.

[0017] By adopting the above technical scheme, the setting of the arc-shaped fire baffle and the air supply angle can provide guidance for the hot air to prevent the hot air from directly impacting the fan, thereby protecting the fan from high temperature damage and helping to extend its service life. At the same time, the air supply angle between the arc-shaped fire baffle and the first connecting part and the second connecting part is an acute angle, so that the hot air forms a vortex inside the fire baffle, further reducing the possibility of open flames burning the fan. This process only allows hot air to flow through, and the fan acts as a power source to draw the hot air into the hot air duct. Through reasonable hot air flow design and thermal insulation protection, the stability and reliability of the entire oven system are significantly improved.

[0020] Blowers are symmetrically set at the feed inlet and the discharge port to strengthen the air circulation inside the box, effectively reduce temperature dead corners and humidity accumulation. When the hydrogen-carbon paper enters and exits, the blower can quickly replenish hot air to reduce the temperature fluctuation inside the box and ensure the stability and continuity of the pre-evaporation process. At the same time, the blower can stir the air in the protective cover to make the air more fluid, thereby reducing impurities adhering to the hydrogen-carbon paper, which helps to improve the quality of the finished product of hydrogen-carbon paper.

[0021] Preferably, the flattening roller group includes a transmission roller, wherein one end of the transmission roller assembled with one side wall of the box is an operating end, and one end of the transmission roller assembled with the other side wall of the box is a transmission end, wherein a bearing seat is provided at the operating end of the box close to the transmission roller, and a first bearing, a second bearing and a third bearing are rotatably provided on the bearing seat, and the operating end of the transmission roller is pressed against the first bearing and the second bearing at the same time, and a space is reserved between the third bearing and the operating end for the transmission roller to expand and deform, and the cooperation of the first bearing, the second bearing and the third bearing is used to limit the rotation stroke of the transmission roller.

[0022] By adopting the above technical solution, when the transmission roller is deformed due to high heat, with the cooperation of the first bearing, the second bearing and the third bearing, space is reserved at the operating end of the transmission roller to allow it to expand and deform at high temperatures, thereby effectively reducing the mechanical resistance between the transmission roller and the bearing, improving the stability and reliability of equipment operation, reducing the situation where the bearing is damaged by thermal expansion of the transmission roller, thereby extending the service life of the entire transmission unit and helping to reduce production costs. At the same time, the coordinated use of the three bearings can more accurately limit the rotation stroke of the transmission roller, thereby improving the accuracy and operational stability of the overall mechanical equipment.

[0023] Preferably, a mounting seat, a heat conductor and a jacket are provided at the driving end of the driving roller near the box body, the jacket is assembled with the driving end of the driving roller, and one end of the jacket away from the driving end is rotatably connected to the heat conductor, and the heat conductor is provided on the mounting seat.

[0024] By adopting the above technical solution, with the cooperation of the heat conductive member and the jacket, one end of the transmission roller is connected to the mounting seat. During this process, the mounting seat provides sufficient support for the transmission roller so that the transmission roller can move stably, and the heat conductive member and the jacket can provide good flexibility and adjustability for the transmission roller. At the same time, the heat conductive member has good thermal conductivity, which can efficiently conduct and dissipate the heat generated by the transmission end of the transmission roller when it moves, avoiding damage to both due to overheating when the power member is directly connected to the transmission roller, which helps to extend the service life of the entire transmission unit.

[0025] Preferably, a fourth bearing is provided between the heat-conducting member and the jacket, an end of the jacket away from the transmission end extends into the heat-conducting member, and the two are connected via the fourth bearing.

[0026] By adopting the above technical solution, the setting of the fourth bearing helps to reduce the friction between the jacket and the heat conductor, which can extend the service life of the equipment to a certain extent, thereby reducing the maintenance cost of the equipment. The introduction of the bearing enables the jacket to rotate smoothly in the heat conductor, ensuring the transmission efficiency and stability of the transmission roller.

[0036] The following is combined with Figure 1-7 This application is described in further detail.

[0037] The embodiment of the present application discloses an oven system for producing hydrogen-producing carbon paper materials.

[0038] Reference Figure 1 and Figure 2A drying oven system for hydrogen-making carbon paper materials includes a box body 1, a heating mechanism 2 and a flattening roller group 5, wherein the box body 1 is vertically provided with an air inlet 11 and an air outlet 12, and the box body 1 is horizontally provided with a feed port 13 and a discharge port 14, and the flattening roller group 5 is arranged in the box body 1, and the carbon hydrogen paper enters from the feed port 13 and is transported to the discharge port 14 through the flattening roller group 5, so that the carbon hydrogen paper can be smoothly transmitted in the box body 1, effectively avoiding wrinkles or unevenness of the material during the drying process, and the heating mechanism 2 is installed on the outside of the box body 1, and can provide a suitable drying temperature for the box body 1.

[0039] Specifically, refer to Figure 2 and Figure 3 The flattening roller group 5 includes a plurality of transmission rollers 51, which are arranged equidistantly and in parallel along the long side of the box body 1, and the two ends of the transmission rollers 51 are respectively connected to the two opposite sides of the long side of the box body 1, so that the extension direction of the transmission rollers 51 is perpendicular to the long side wall of the box body 1. The present application can be provided with a plurality of flattening roller groups 5 to cooperate with the transport of carbon hydrogen paper, so that the carbon hydrogen paper can maintain appropriate tension during the transport process, making the production smoother.

[0040] It is assumed that one end of the transmission roller 51 assembled with a long side wall of the box body 1 is the operating end 511, and one end of the transmission roller 51 assembled with the other side wall of the box body 1 is the transmission end 512, wherein a bearing seat 54 is provided at the operating end 511 of the box body 1 close to the transmission roller 51, and a first bearing (not shown in the figure), a second bearing 52 and a third bearing 53 are rotatably provided on the bearing seat 54, and the three are distributed in a triangular shape, so that the third bearing 53 is placed on the center line of the first bearing and the second bearing 52, and the operating end 511 of the transmission roller 51 is pressed against the first bearing and the second bearing 52 at the same time, and a space is reserved between the third bearing 53 and the operating end 511 for the transmission roller 51 to expand and deform, and the cooperation of the first bearing, the second bearing 52 and the third bearing 53 is used to limit the rotation stroke of the transmission roller 51.

[0041] In the present application, when the transmission roller 51 is deformed due to high heat, with the cooperation of the first bearing, the second bearing 52 and the third bearing 53, space is reserved at the operating end 511 of the transmission roller 51 to allow it to expand and deform at high temperatures, thereby reducing the mechanical resistance between the transmission roller 51 and the bearing, improving the stability and reliability of the equipment operation, reducing the possibility of bearing damage due to thermal expansion of the transmission roller 51, and achieving the purpose of extending the service life of the entire transmission unit.

[0042] Reference Figure 2 and Figure 3In the present application, a mounting seat 55, a heat conductor 56 and a jacket 57 are provided at the transmission end 512 of the transmission roller 51 of the box body 1. The jacket 57 is assembled with the transmission end 512 of the transmission roller 51. One end of the jacket 57 away from the transmission end 512 is rotatably connected to the heat conductor 56. The heat conductor 56 is provided on the mounting seat 55.

[0043] Specifically, the heat conductor 56 and the jacket 57 are both metal parts, such as aluminum parts, to improve the thermal conductivity of the two. The part where the jacket 57 is assembled with the transmission end 512 of the transmission roller 51 is in a cup-shaped structure. The jacket 57 surrounds the transmission end 512, and the end of the jacket 57 away from the transmission end 512 is in a circular shaft structure. A fourth bearing 58 is arranged between the heat conductor 56 and the jacket 57. The end of the jacket 57 away from the transmission end 512 extends into the heat conductor 56, and the two are connected by the fourth bearing 58. In addition, there is at least one fourth bearing 58, and multiple fourth bearings 58 are equidistantly and parallelly assembled on the outer wall of the jacket 57, so that the relative movement between the jacket 57 and the heat conductor 56 is smoother, further reducing the friction between the two, which helps to extend the service life of the transmission unit.

[0044] In this application, reference is made to Figure 2 and Figure 3 The fourth bearing 58 is provided to reduce the friction between the jacket 57 and the heat-conducting member 56, which can extend the service life of the equipment to a certain extent, thereby reducing the maintenance cost of the equipment. The introduction of the bearing enables the jacket 57 to rotate smoothly in the heat-conducting member 56, ensuring the transmission efficiency and stability of the transmission roller 51. Under the cooperation of the heat-conducting member 56 and the jacket 57, one end of the transmission roller 51 is connected to the mounting seat 55. In this process, the mounting seat 55 provides sufficient support for the transmission roller 51, so that the transmission roller 51 can move stably. The heat-conducting member 56 has good thermal conductivity, which can efficiently conduct and dissipate the heat generated by the transmission end 512 of the transmission roller 51 when it moves, avoiding the damage of the power member 59 and the transmission roller 51 due to overheating when the power member 59 is directly connected to the transmission roller 51, which helps to extend the service life of the entire transmission unit.

[0045] Furthermore, a power component 59 is provided on the mounting seat 55, and the portion of the jacket 57 passing through the heat conductive member 56 is assembled with the power component 59, and the power component 59 is used to drive the jacket 57 to rotate, wherein the power component 59 includes a driving sprocket 591, a driven sprocket 592, a chain 593 and a driving motor 594, wherein the driving motor 594 is fixed on the mounting seat 55, the driving sprocket 591 is assembled at the output end of the driving motor 594, the driven sprocket 592 is assembled at the portion of the jacket 57 passing through the heat conductive member 56, and the chain 593 is meshed with the driving sprocket 591 and the driven sprocket 592 at the same time.

[0046] Under the action of the driving motor 594, the active sprocket 591, the driven sprocket 592 and the chain 593 can rotate at the same time, thereby driving the jacket 57 and the transmission roller 51 to rotate, which helps to improve the transportation efficiency and operational convenience of carbon paper. In this application, the transmission method of the sprocket and chain 593 is adopted, which helps to improve the transmission stability and reliability of the transmission roller 51 and reduce the failure rate. In addition, the transmission structure of the sprocket and chain 593 is relatively simple, which is convenient for daily maintenance and replacement. By driving the motor 594, the rotation of the jacket 57 can be accurately controlled to meet production needs.

[0047] The oven system of the present application is applied to hydrogen-making carbon paper materials. Hydrogen carbon paper is also called carbon fiber paper. It has a uniform porous structure, which makes it have excellent air permeability and can effectively transfer gas. At the same time, carbon hydrogen paper is affected by the carbon fiber weaving structure, is brittle, easily cracked under stress, and has poor strength and durability. At the same time, the carbon hydrogen paper in the present application has been treated with a hydrophobic agent, so that it has good hydrophobicity, can allow water vapor, gas, etc. to be discharged smoothly, and water droplets will not accumulate in the pores or surface of the carbon hydrogen paper itself.

[0048] When the flattening roller group 5 is used to transport the hydrogen-carbon paper, the hydrogen-carbon paper is not allowed to be folded or bent during traction. The double-roller clamping traction or double-roller staggered clamping traction method can be adopted. Compared with the two methods, the second traction method is preferred. The reason is that the double-roller staggered clamping method can not only provide tension for the carbon hydrogen paper in the process of moving forward, but also avoid the situation where the carbon hydrogen paper is clamped off due to excessive force when the double rollers are in direct contact, so that the carbon hydrogen paper can maintain a high-quality state and be continuously pulled.

[0049] In order to dry the hydrogen carbon paper, refer to Figure 4 and Figure 5 The heating mechanism 2 includes a body 21, a heating source 22, a fire baffle 23 and a fan 24, wherein the heating source 22 is a gas engine, the body 21 is fixed to the top of the box body 1, a hot air duct 211 and a cold air duct 212 are arranged in the body 21, the air inlet 11 is arranged at the connection position between the hot air duct 211 and the box body 1, and the air outlet 12 is arranged at the connection position between the cold air duct 212 and the box body 1, the heating source 22, the fire baffle 23 and the fan 24 are all installed in the body 21, and the heating source 22 and the fan 24 are separated by the fire baffle 23 to prevent high temperature from damaging sensitive components such as the fan 24, thereby improving the safety and service life of the equipment.

[0050] A heat preservation mechanism 214 is provided in the machine body 21, and the heat preservation mechanism 214 is provided between the hot air duct 211 and the cold air duct 212.

The heating source 22 is installed at the air converging duct 213 near the junction of the cold air duct 212 and the air inlet duct 214, and the fan 24 is installed at the air converging duct 213 near the entrance of the hot air duct 211.

[0051] In the present application, the fire baffle 23 includes a first connecting portion 231, a second connecting portion 232 and a curved fire baffle 233, one end of the first connecting portion 231 is fixed to the top end of the curved fire baffle 233, one end of the second connecting portion 232 is fixed to the bottom end of the curved fire baffle 233, the opening of the curved fire baffle 233 faces the fan 24, and an air supply angle 234 is set between the curved fire baffle 233 and the first connecting portion 231 and between the curved fire baffle 233 and the second connecting portion 232, and the air supply angle 234 is an acute angle.

[0052] When in use, start the exhaust fan and the fan 24, the exhaust fan draws external air into the air duct 213, the heating source 22 uses open flame combustion to heat the air in the air duct 213, so that the air in the air duct 213 is rapidly heated, and the fan 24 transmits the heated hot air to the hot air duct 211, and then enters the box 1 through the air inlet 11 to dry the hydrogen-carbon paper in the box 1, and then the cold air circulates back along the air outlet 12 into the cold air duct 212, and circulates in sequence.

[0053] In the present application, a heating source 22 is used to heat the air in the machine body 21, so that the air in the hot air duct 211 can be quickly and evenly heated to the required temperature, and the fan 24 is used to supply hot air to the box body 1. Such operation can ensure accurate control of the temperature during the drying process, thereby ensuring product quality, and the setting of the cold air duct 212 allows the hot air discharged from the box body 1 to be recycled to reduce energy consumption and emissions; by making the air supply angle 234 between the arc-shaped fire baffle 233 and the first connecting part 231 and the second connecting part 232 an acute angle, the hot air forms a vortex inside the fire baffle 23, further reducing the possibility of open flames burning the fan 24. This process only allows hot air to flow through, and the fan 24 acts as a power source to draw the hot air into the hot air duct 211. Through reasonable hot air flow direction design and thermal insulation protection, the stability and reliability of the entire oven system are significantly improved.

After the three are assembled, a "J"-shaped ventilation corridor is formed, and one end of the first ventilation duct 2142 away from the insulation chamber 2141 is connected to the cold air duct 212, and one end of the second ventilation duct 2143 away from the insulation chamber 2141 is connected to the hot air duct 211.

[0055] The "J"-shaped ventilation corridor connects the cold air duct 212 with the hot air duct 211. At the same time, by setting a blocking member 2144, the direct mixing of cold and hot air is reduced, and the hot air is mixed and retained in the insulation chamber 2141, so that the temperature of the insulation box is between the temperatures of the hot air and the cold air. On the one hand, the temperature of the hot air can be guaranteed and the waste of energy can be reduced, so that the hot air can maintain a stable temperature during the transmission process, and the impact of temperature fluctuations on the drying process can be reduced; on the other hand, the cold air can be preheated when it flows back along the cold air duct 212, thereby reducing the energy consumed by the system to maintain the required temperature, which is helpful to achieve the purpose of energy conservation and emission reduction. In this application, through reasonable ventilation duct design, the possibility of high-temperature gas in the hot air duct 211 directly contacting the cold air duct 212 is reduced, thereby reducing the risk of damage to the equipment due to thermal expansion and contraction or other reasons, thereby improving the safety of the equipment.

[0056] Reference Figure 5 The oven system also includes an upper air duct 3 and a lower air duct 4. The output end of the heating mechanism 2 is assembled with the upper air duct 3. The upper air duct 3 is fixed to the inner top wall of the box body 1, and the lower air duct 4 is fixed to the inner bottom wall of the box body 1. The upper air duct 3 and the lower air duct 4 are arranged opposite to each other, and a first drainage cavity 15 for hot air circulation and a second drainage cavity 16 for cold air return are arranged between the two.

[0057] With the cooperation of the upper air guide cover 3, the lower air guide cover 4, the first drainage chamber 15 and the second drainage chamber 16, the hot air and the cold air can circulate along a specific path, so that the hot air covers the front and back sides of the carbon hydrogen paper, so that the carbon hydrogen paper can be evenly heated during the drying process, which helps to improve the drying quality and efficiency.

[0058] In the present application, the shape of the upper air guide hood 3 is consistent with that of the lower air guide hood 4. Specifically, the upper air guide hood 3 includes a fixed portion 31, a first air guide portion 32, a second air guide portion 33, a connecting portion 34 and a speaker air guide portion 35, wherein one end of the connecting portion 34 is assembled with the first air guide portion 32, and the other end is assembled with the second air guide portion 33. At the same time, one end of the fixed portion 31 is assembled with the first air guide portion 32, and the other end is assembled with the second air guide portion 33, and the first air guide portion 32 is tilted downward from the connecting portion 34 to the fixed portion 31, and the second air guide portion 33 is tilted downward from the connecting portion 34 to the fixed portion 31. The speaker air guide portion 35 is connected to the inner cavity of the hot air duct 211 and the upper air guide hood 3, and the trumpet mouth faces the side away from the hot air duct 211, thereby playing a role in guiding and draining.

[0059] More specifically, the fixed portion 31 is provided with a plurality of air nozzles 37 along its length direction, and the number of the air nozzles 37 is an even number greater than two. The present application divides all the air nozzles 37 placed in the upper air guide cover 3 into two equal groups, and the two groups of air nozzles 37 are symmetrically arranged along the length center line of the fixed portion 31, so that the openings of the two groups of air nozzles 37 are both facing the center of the upper air guide cover 3. At the same time, all the air nozzles 37 located on the upper air guide cover 3 are aligned with the upper surface of the hydrogen-carbon paper.

[0060] When in use, the fan 24 transfers the hot air at the air confluence duct 213 to the hot air duct 211, and the hot air then enters the inner cavity of the upper air guide cover 3 from the air inlet 11. Under the cooperation of the first air guide part 32, the second air guide part 33 and the speaker air guide part 35, it can provide guidance and drainage, so that the hot air is forced into the air nozzle 37, and the air nozzle 37 finally outputs the hot air. In the present application, due to the specific installation direction of the two groups of air nozzles 37, the hot air stored in the upper air guide hood 3 can always gather in the middle of the box body 1 instead of being discharged from the discharge port 14 or the feed port 13, making the production process more energy-efficient; at the same time, the hot air in the upper air guide hood 3 is slowly blown from the left and right directions, which can realize hot air convection and enhance the flow rate, and can accelerate the drying speed of the hydrogen-carbon paper to a certain extent; at the same time, the hot air in the upper air guide hood 3 is slowly blown from the left and right directions, which can avoid the wrinkling of the hydrogen-carbon paper caused by one-way blowing, thereby affecting the quality of the carbon hydrogen paper; at the same time, because the carbon hydrogen paper has good air permeability and hydrophobicity, the hot air can pass through the structural pore size of the carbon hydrogen paper, further accelerating the drying efficiency of the carbon hydrogen paper, and in the process of temperature difference fluctuation, water will not be retained on the carbon hydrogen paper when condensing, ensuring its production quality.

[0061] Similarly, the lower air guide cover 4 is fixed in the box body 1 in the same installation method as the upper air guide cover 3, and no repetition is given here. In the present application, a partition frame 38 is provided in the box body 1, and the partition frame 38 is fixed above the upper air guide cover 3 so that the hot air duct 211 is connected thereto.

[0062] Further, refer to Figure 5 , the partition frame 38 covers the entire upper air guide cover 3, the first drainage chamber 15 is formed between the partition frame 38 and the upper air guide cover 3, a part of the hot air at the hot air duct 211 enters the inner cavity of the upper air guide cover 3 from the horn air guide part 35, and then blows out from the air nozzle 37 placed in the upper air guide cover 3, and the hot air covers the entire upper surface of the hydrogen carbon paper; another part of the hot air at the hot air duct 211 enters the inner cavity of the lower air guide cover 4 along the first drainage chamber 15, and then blows out from the air nozzle 37 placed in the lower air guide cover 4, and the hot air covers the entire lower surface of the hydrogen carbon paper. In addition, the second drainage chamber 16 is formed between the outside of the partition frame 38 and the cold air duct 212, the hot air at the upper air guide cover 3 and the lower air guide cover 4 is cooled after drying the carbon hydrogen paper, and the cold air of this part enters the cold air duct 212 along the second drainage chamber 16, and the cold air enters the converging air duct 213 in turn and is heated by the heating source 22, and the process is repeated to realize the circulation of hot and cold air.

[0063] Since the coating needs to be cured at a certain temperature to form a protective layer, the present application ensures that both sides of the paper are evenly dried by heating and drying the carbon hydrogen paper on both sides, avoiding deformation or uneven shrinkage of the paper caused by single-sided heating. At the same time, double-sided heating can ensure that the coating is fully cured on both sides of the paper, which helps the coating to better combine with the paper fibers, thereby improving the durability of the finished product and the overall stability of the paper; and when the temperature in the box 1 fluctuates greatly, it will affect the temperature and humidity of the entire box 1. Double-sided heating and drying can more effectively combat this and ensure the uniform drying of the carbon hydrogen paper, thereby improving the drying quality.

[0064] In the present application, another preferred structure of the upper air guide cover 3 or the lower air guide cover 4 is provided. The structures of the two are consistent. One of them is selected for explanation here. Figure 6 On the basis of the original upper wind guide hood 3, a double-roller wind shield 36 is added. The double-roller wind shield 36 includes two roller wind shields 36, and the extension direction of the two roller wind shields is consistent with the transportation direction of the hydrocarbon paper, and the two roller wind shields are rotatably installed inside the upper wind guide hood 3 by means of shaft connection. A motor can be used as a power source and a gear set as a connecting mechanism to drive the two roller wind shields 36 to move in opposite directions, and the output end of the speaker air guide part 35 is aligned with the middle of the double-roller wind shield 36.

[0065] When in use, the hot air enters the inner cavity of the upper air guide cover 3 from the air inlet 11. When the double roller wind shield 36 is in the open state, the hot air that fills the inner cavity of the upper air guide cover 3 and enters each air nozzle 37 at the same time in the double roller wind shield 36, achieving the effect of synchronous heating and drying of each area of ​​the upper layer of the carbon hydrogen paper; when the double roller wind shield 36 is in the closed state, the hot air accumulates heat to prepare for the next drying. By setting it in this way, the time difference of hot air drying of carbon hydrogen paper in different areas can be effectively shortened, which helps to further improve the drying effect of carbon hydrogen paper.

[0066] Reference Figure 1 and Figure 7 Insulation pads 25 are installed on the inner wall of the insulation cavity 2141 and inside the blocking member 2144, and a first keel frame 261 is provided at the corner of the insulation pad 25 arranged in the insulation cavity 2141; insulation pads 27 are installed on the inner wall of the box body 1 and the inner wall of the machine body 21, and a second keel frame 262 is provided at the corner of the insulation pad 27.

[0067] The insulation pad 25 installed on the inner wall of the insulation chamber 2141 and the inside of the blocking member 2144, as well as the first keel frame 261 set at the corner, jointly enhance the insulation effect. Such a setting can not only reduce heat loss and improve the efficiency of heat energy utilization, but also ensure that the temperature inside the oven is more uniform and stable.

[0068] The thermal insulation pads 27 installed on the inner walls of the box body 1 and the machine body 21, and the second keel frame 262 set at the corners, further enhance the thermal insulation performance, help prevent overheating of the outside of the oven, improve operational safety, and reduce the impact of ambient temperature on the internal temperature of the oven; the addition of the first keel frame 261 and the second keel frame 262 helps to enhance the thermal insulation stability and heat insulation stability of the entire system.

[0069] In addition, a heat preservation cover 6 is provided at both the feed port 13 and the discharge port 14, and a heater is provided on the heat preservation cover 6 for adjusting the temperature of the air in the heat preservation cover 6; a blower 24 is provided on the heat preservation cover 6, and the blower 24 at the feed port 13 and the blower 24 at the discharge port 14 are symmetrically arranged along the center line of the long side of the box body 1, and the opening of the blower 24 faces the center of the box body 1.

[0070] The heat preservation covers 6 of the feed port 13 and the discharge port 14 are both provided with heating elements, which can adjust the temperature of the air so that the hydrogen-carbon paper can maintain a constant temperature environment when entering and leaving the box 1, which helps to reduce the impact of temperature fluctuations on the quality of the hydrogen-carbon paper and ensure the quality of the hydrogen-carbon paper during the drying process.

[0071] Blowers 24 are symmetrically arranged at the feed port 13 and the discharge port 14, which strengthens the air circulation inside the box 1 and effectively reduces temperature dead corners and humidity accumulation. When the hydrogen-carbon paper enters and exits, the blower 24 can quickly replenish hot air, reduce the temperature fluctuation inside the box 1, and ensure the stability and continuity of the pre-evaporation process. At the same time, the blower 24 can stir the air in the protective cover to make the air more fluid, thereby reducing impurities adhering to the hydrogen-carbon paper, which helps to improve the quality of the finished product of the hydrogen-carbon paper.

[0072] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
