Description

Technical Field

[0001] The present invention relates to the technical field of drying, and specifically to a drying process for the production of epoxy coils and a group heating type coil oven. Background Art

[0002] Epoxy coils are a new type of flooring material in the flooring industry. It is a polymer composite material based on an elastomer toughened epoxy resin and a polyurethane compound resin system, toughened and reinforced with glass fiber, and prepared through a special curing process. The group coil oven divides the oven into multiple independent heating zones (such as a preheating zone, a constant speed drying zone, a curing zone, etc.) along the running direction of the coil. Each zone can independently control the temperature, air volume, and air flow direction, enabling the coil to receive targeted heat supply at different drying stages, thereby efficiently completing the solvent volatilization, curing, or cross-linking reaction of the coating layer (such as glue, paint, ink, etc.), and ensuring the stable quality of the coating.

[0003] During the drying process of existing coils, it is easy to generate bubbles and pinholes on the surface of the coils. The coils are prone to folding during movement, resulting in an impact on the drying effect and low drying efficiency of the equipment. Therefore, a new design has been carried out for this situation. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A drying process for the production of epoxy coils and a group heating type coil oven, including a compound mechanism. A cooling mechanism is fixedly connected to the outside of the compound mechanism, and a processing mechanism is fixedly connected to one side outside the compound mechanism; The compound mechanism includes a compound housing. A square connection end is fixedly connected to the top of the inner wall of the compound housing. A heater is fixedly connected to the inside of the square connection end. A partition is fixedly connected to the bottom of the square connection end. A partition is arranged outside the heater for group heating to meet different operation requirements. A first receiving platform is fixedly connected to one side outside the compound housing. A first slide rail is fixedly connected to the top of the first receiving platform. A receiving frame is slidably connected to the outside of the first slide rail. A roller mechanism is fixedly connected to the bottom of the inner wall of the compound housing. The coil passes through the roller mechanism, and the movement range of the coil is restricted by the roller mechanism, enabling the material to be dried and heated in a flat state, preventing the coil from curling and affecting the heating and drying effect. A winding mechanism is fixedly connected to the side of the compound housing away from the first receiving platform. The coil is placed in the middle of the receiving frame, and then the two receiving frames are docked on the first slide rail to achieve the function of placing the coil. One end of the coil is set on the winding mechanism. During the winding process of the coil by the winding mechanism, it comes into contact with the heater to continuously dry the coil, dry the coating on the surface of the coil, and cure the coating. The dried coil is convenient for subsequent processing and treatment.

[0005] Preferably, the roller mechanism includes a roller bracket. An external bracket is fixedly connected between the opposite surfaces of the roller bracket. A first roller is fixedly connected between the opposite surfaces of the external bracket. The first roller supports the coil material to prevent the middle part of the coil material from sagging during the winding process due to the long travel, contacting the surface of the equipment, and affecting the drying effect during the winding process. An external block is fixedly connected to the top of the external bracket. A second roller is fixedly connected between the opposite surfaces of the external block. The second roller is arranged on the upper layer of the first roller, and the two are adapted to achieve a limiting effect on the coil material, avoiding folding or overlapping of the coil material during the winding process, thereby affecting the drying effect of the coil material, preventing uneven drying of the coil material, and thus avoiding affecting the product quality.

[0006] Preferably, the winding mechanism includes a second receiving platform. A second sliding rail is fixedly connected to the top of the second receiving platform. A sliding frame is slidably connected to the outside of the second sliding rail. The sliding frame slides on the second sliding rail to facilitate adjusting the clamping range and achieve the effect of adjusting coil materials of different sizes. When the connecting rod is inserted into the component, a connecting rod is fixedly connected to one side of the outside of the sliding frame. A buffer mechanism is fixedly connected to the outside of the connecting rod. The buffer mechanism plays a role of shock absorption and buffering, slowing down the clamping force and speed, preventing over-clamping due to malfunctions, and providing a certain protective effect on the component. A motor is fixedly connected to the side of the outside of the sliding frame away from the connecting rod. A friction mechanism is fixedly connected to one side of the outside of the buffer mechanism. The buffer mechanism is arranged on both sides of the coil roll to squeeze both sides of the coil material, reduce deviation during the winding process, and prevent affecting the subsequent operation effect. Secondly, the motor drives the connecting rod to rotate to achieve the effect of automatically winding the coil material.

[0007] Preferably, the buffer mechanism includes a buffer plate. A connecting rod is fixedly connected to one side of the outside of the buffer plate. A first spring is sleeved on the outside of the connecting rod. A receiving plate is slidably connected to the outside of the connecting rod. The inner side of the receiving plate is fixedly connected to the outside of the connecting rod. The side of the outside of the receiving plate away from the buffer plate is fixedly connected to the outside of the friction mechanism. When the buffer plate is impacted by pressure on one side, the buffer plate slides towards the receiving plate side, squeezing the first spring through the connecting rod to play a role of shock absorption and buffering, reducing the extrusion pressure. At the same time, the buffer plate is supported by the reaction force of the spring, clamping both sides of the coil material to play a role of restricting the coil material and reducing the occurrence of deviation during the winding process.

[0008] Preferably, the friction mechanism includes a friction housing, a friction bracket is fixedly connected to the inner side of the friction housing, a connecting plate is fixedly connected to the outer side of the friction bracket, and a silica gel plate is fixedly connected to the side of the connecting plate away from the friction housing. When the connecting rod is released from extrusion, the spring rebounds, and rapid ejection easily causes mechanical wear, thus affecting the service life of the components. By rubbing the silica gel plate against the outer side of the connecting rod, the resistance between the components is increased, thereby achieving the effect of slowing down the sliding speed of the components, reducing the wear between the components, and extending the service life of the components. Grooves are formed on the surface of the silica gel plate, and the deformation performance of the components is increased by grooving, thereby further improving the friction and buffering effects. A second spring is fixedly connected to the inner side of the friction bracket. When the silica gel plate rubs against the surface of the component, the component is likely to vibrate. The second spring plays a buffering role to reduce the vibration amplitude of the component and improve the stability of the component.

[0009] Preferably, the processing mechanism includes a blower. By generating wind with the blower, the hot air flow inside the composite mechanism is discharged to the outside, thereby achieving the regulation of the temperature and humidity inside the equipment, which is beneficial to improving the drying efficiency and the stability of product quality, ensuring fresh air. Continuous ventilation can maintain the freshness of the air inside the oven, provide a good working environment for the operator, reduce the harm of harmful gases to the human body, and protect the physical health of the operator. Volatile substances are discharged. During the drying process of the epoxy coil, the solvents and moisture in the coating will volatilize. Ventilation can timely discharge the volatile substances from the oven, so that the solvents and moisture on the surface of the coil can volatilize quickly and evenly, thereby improving the drying quality. One side of the outside of the blower is fixedly connected to the outside of the composite housing, and a ventilation pipe is fixedly connected to the side of the blower away from the composite housing. The side of the ventilation pipe away from the blower is connected to an annular housing in an inserted manner, and a filter plate is fixedly connected to the inner side of the annular housing. The air flow moves towards the filter plate through the ventilation pipe, and the air flow is filtered by the filter plate to reduce the emission of harmful substances to the outside and reduce the impact on the human body, optimizing the working environment. A chip removal pipe is fixedly connected to the outside of the ventilation pipe, and a rotating mechanism is fixedly connected to the inner wall of the ventilation pipe. After long-term operation, impurities or particles are likely to accumulate on the inner wall of the ventilation pipe. The rotating mechanism is rotated by the wind force to clean the impurities on the inner wall, and then the impurities are discharged to the outside through the chip removal pipe.

[0010] Preferably, the rotation mechanism includes a fixed frame. A connecting shaft is fixedly connected between opposite surfaces of the fixed frame. A rotating column is rotatably connected to the outer side of the connecting shaft. A rotating frame is fixedly connected to the outer side of the rotating column. A scraping plate is fixedly connected to a side of the outer part of the rotating frame away from the rotating column. The rotating frame is driven to rotate by the circular paddle, so that the scraping plate rubs the inner wall of the pipeline, thereby cleaning the impurities on the inner wall of the pipeline, reducing the accumulation of impurities on the inner wall of the pipeline, and avoiding excessive accumulation of impurities, so as to affect the air flow effect inside the pipeline. A circular paddle is fixedly connected to the groove of the outer part of the rotating frame. The circular paddle is arranged on the rotating frame. When the air flow flows inside the ventilation pipe, it impacts the outer side of the circular paddle, so that the air flow drives the circular paddle to rotate.

[0011] Preferably, the cooling mechanism includes a cooling frame base. The bottom of the cooling frame base is fixedly connected to the top of the second receiving platform. A frame body is fixedly connected to the top of the cooling frame base. An electric push rod is fixedly connected to the bottom of the frame body. After the coil is dried, during the process of moving towards the winding mechanism, the height of the square pipeline is adjusted by the electric push rod, so as to facilitate the square pipeline to fit on the surface of the coil, thereby achieving the effect of cooling the coil and preventing the coil from deforming. The temperature of the dried coil is relatively high. If it is directly wound or processed subsequently, due to the effect of thermal expansion and contraction, the coil may deform, shrink or wrinkle during the cooling process, affecting the flatness and dimensional stability of the coil. Through the cooling treatment, the coil can be shaped at a relatively stable temperature, reducing the possibility of deformation. A square pipeline is fixedly connected to a side of the outer part of the electric push rod away from the frame body. A first port is fixedly connected to a side of the outer part of the square pipeline. A second port is fixedly connected to a side of the outer part of the square pipeline away from the first port. The cooling liquid enters from the first port and exits from the second port, so as to continuously feed the liquid and ensure continuous cooling.

[0012] A drying process for epoxy coil production includes the following steps: Step 1, placement: Place the coil on one side of the compound mechanism. Pass one end of the coil through the roller mechanism and set it on the winding mechanism. Control the movement and drying of the coil through the winding mechanism. Step 2, drying: The coil passes through the inside of the compound housing, and the surface of the coil is heated by the heater to achieve the drying operation of the coil. Step 3, ventilation: The processing mechanism is arranged on both sides of the compound housing, and the temperature inside the equipment and volatile substances are adjusted through the processing mechanism. Step 4, cooling: The coil moves towards the winding mechanism side and contacts the cooling mechanism. The coil is cooled by the cooling mechanism to prevent the coil from deforming.

[0013] The present invention provides a group heating type coil oven for epoxy coil production. It has the following beneficial effects: 1. The group heating type coil oven for epoxy coil production, through the design of the composite mechanism, places the coil in the middle of the receiving rack, and then the two receiving racks are butted on the first slide rail to achieve the function of placing the coil. One end of the coil is set on the winding mechanism. During the winding process of the winding mechanism on the coil, it contacts the heater to continuously dry the coil, dry the coating on the coil surface, and cure the coating. The dried coil is convenient for subsequent processing and treatment. A partition is set outside the heater for group heating to meet different operation requirements. The coil passes through the roller mechanism, and the roller mechanism restricts the movement range of the coil to keep the material in a flat state for drying and heating, preventing the coil from curling and affecting the heating and drying effect.

[0014] 2. The group heating type coil oven for epoxy coil production, through the design of the friction mechanism, when the connecting rod is released from extrusion, the spring rebounds. The rapid ejection easily causes mechanical wear, thus affecting the service life of the components. By rubbing the outer side of the connecting rod with the silica gel plate, the resistance between the components is increased, thereby achieving the function of slowing down the sliding speed of the components, reducing the wear between the components, and extending the service life of the components. The surface of the silica gel plate is provided with grooves, and the deformation performance of the components is increased by grooving, thereby further improving the friction and buffering effects. When the silica gel plate rubs against the surface of the components, it is easy to cause the components to vibrate. The second spring plays a buffering role to reduce the vibration amplitude of the components and improve the stability of the components.

[0015] 3. The group heating type coil oven for epoxy coil production, through the design of the treatment mechanism, generates wind through the fan to discharge the hot air flow inside the composite mechanism to the outside, thereby achieving the adjustment of the temperature and humidity inside the equipment, being beneficial to improving the drying efficiency and the stability of product quality, ensuring fresh air. Continuous ventilation can maintain the freshness of the air inside the oven, provide a good working environment for the operators, reduce the harm of harmful gases to the human body, and protect the physical health of the operators. Discharge volatile substances. During the drying process of the epoxy coil, the solvents and moisture in the coating will volatilize. Ventilation can timely discharge the volatile substances from the oven, enabling the solvents and moisture on the coil surface to volatilize quickly and evenly, thereby improving the drying quality. The air flow moves towards the filter plate through the ventilation pipe, and the filter plate filters the air flow to reduce the emission of harmful substances to the outside and reduce the impact on the human body, optimizing the operation environment. After long-term operation, impurities or particles are likely to accumulate on the inner wall of the ventilation pipe. The rotation mechanism is rotated by the wind force to clean the impurities on the inner wall, and then the impurities are discharged to the outside through the chip removal pipe.

[0016] IV. The group heating type coil oven for epoxy coil production, through the design of the winding mechanism, the sliding frame slides on the second slide rail, so as to facilitate the adjustment of the clamping range, and thus achieve the function of adjusting coils of different sizes. When the receiving rod penetrates the components, the buffer mechanism plays a role in shock absorption and buffering, slowing down the clamping force and speed, preventing over-clamping due to failures, and playing a certain protective effect on the components. The buffer mechanism is arranged on both sides of the coil roll to squeeze both sides of the coil, reduce deviation during the winding process, and prevent affecting the subsequent operation effect. Secondly, the motor drives the receiving rod to rotate, so as to achieve the function of automatically winding the coil.

[0017] V. The group heating type coil oven for epoxy coil production, through the design of the cooling mechanism, after the coil is dried, during the process of moving towards the winding mechanism, the height of the square pipe is adjusted by the electric push rod, so as to facilitate the square pipe to fit on the surface of the coil, and thus achieve the function of cooling the coil and preventing the coil from deforming. The temperature of the dried coil is relatively high. If it is directly wound or processed subsequently, due to the effect of thermal expansion and contraction, the coil may deform, shrink or wrinkle during the cooling process, affecting the flatness and dimensional stability of the coil. Through the cooling treatment, the coil can be shaped at a relatively stable temperature, reducing the possibility of deformation. The cooling liquid enters from the first port and exits from the second port, so as to continuously supply liquid and ensure continuous cooling. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] The first embodiment is as Figures 1 to 6 shown. The present invention provides a technical solution: a group heating type coil oven for epoxy coil production, including a composite mechanism 1, a cooling mechanism 3 is fixedly connected to the outside of the composite mechanism 1, and a processing mechanism 2 is fixedly connected to one side outside the composite mechanism 1; The composite mechanism 1 includes a composite housing 11. At the top of the inner wall of the composite housing 11, a square connection end 12 is fixedly connected. Inside the square connection end 12, a heater 13 is fixedly connected. At the bottom of the square connection end 12, a partition 14 is fixedly connected. On one side of the outside of the composite housing 11, a first receiving platform 15 is fixedly connected. On the top of the first receiving platform 15, a first slide rail 16 is fixedly connected. A receiving frame 17 is slidably connected to the outside of the first slide rail 16. At the bottom of the inner wall of the composite housing 11, a roller mechanism 18 is fixedly connected. On the side of the outside of the composite housing 11 away from the first receiving platform 15, a winding mechanism 19 is fixedly connected. Place the coil in the middle of the receiving frame 17, and then dock the two receiving frames 17 on the first slide rail 16 to achieve the function of placing the coil. Set one end of the coil on the winding mechanism 19. During the winding process of the winding mechanism 19 on the coil, it comes into contact with the heater 13 to continuously dry the coil, dry the coating on the surface of the coil, and cure the coating. The dried coil is convenient for subsequent processing and treatment. A partition 14 is provided outside the heater 13 for grouped heating to meet different operation requirements. The coil passes through the roller mechanism 18, and the roller mechanism 18 restricts the moving range of the coil to keep the material in a flat state for drying and heating, preventing the coil from curling and affecting the heating and drying effect.

[0022] The roller mechanism 18 includes a roller support 181. Between the opposite faces of the roller support 181, an external connection frame 182 is fixedly connected. Between the opposite faces of the external connection frame 182, a first roller 183 is fixedly connected. On the top of the external connection frame 182, an external connection block 184 is fixedly connected. Between the opposite faces of the external connection block 184, a second roller 185 is fixedly connected. The first roller 183 supports the coil to prevent the middle part of the coil from sagging and contacting the surface of the equipment during the winding process due to the long travel, which affects the drying effect during the winding process. The second roller 185 is arranged on the upper layer of the first roller 183, and the two are adapted to achieve the limiting effect on the coil, avoiding the coil from folding or overlapping during the winding process, which affects the drying effect of the coil and prevents the coil from being unevenly dried, thus avoiding affecting the product quality.

[0023] The coiling mechanism 19 includes a second receiving table 191. A second sliding rail 192 is fixedly connected to the top of the second receiving table 191. A sliding frame 193 is slidably connected to the outside of the second sliding rail 192. A receiving rod 194 is fixedly connected to one side of the outside of the sliding frame 193. A buffer mechanism 195 is fixedly connected to the outside of the receiving rod 194. A motor 196 is fixedly connected to the side of the outside of the sliding frame 193 away from the receiving rod 194. A friction mechanism 197 is fixedly connected to one side of the outside of the buffer mechanism 195. The sliding frame 193 slides on the second sliding rail 192, so as to facilitate adjusting the clamping range, thereby achieving the effect of adjusting coils of different sizes. When the receiving rod 194 is inserted into components, the buffer mechanism 195 plays a role of shock absorption and buffering, slowing down the clamping force and speed, preventing over-clamping due to malfunctions, and providing a certain degree of protection for the components. The buffer mechanism 195 is arranged on both sides of the coil roll to squeeze both sides of the coil, reducing deviation during the coiling process and preventing it from affecting the subsequent operation effect. Secondly, the motor 196 drives the receiving rod 194 to rotate, thereby achieving the effect of automatically coiling the coil.

[0024] The buffer mechanism 195 includes a buffer plate 1951. A connecting rod 1952 is fixedly connected to one side of the outside of the buffer plate 1951. A first spring 1953 is sleeved on the outside of the connecting rod 1952. A receiving plate 1954 is slidably connected to the outside of the connecting rod 1952. The inner side of the receiving plate 1954 is fixedly connected to the outside of the receiving rod 194. The side of the outside of the receiving plate 1954 away from the buffer plate 1951 is fixedly connected to the outside of the friction mechanism 197. When one side of the buffer plate 1951 is subjected to a pressure impact, the buffer plate 1951 slides towards the receiving plate 1954 side, squeezing the first spring 1953 through the connecting rod 1952, thereby playing a role of shock absorption and buffering, reducing the extrusion pressure. At the same time, the buffer plate 1951 is supported by the reaction force of the spring, clamping both sides of the coil, thereby playing a role of restricting the coil and reducing the occurrence of deviation during the coiling process.

[0025] The friction mechanism 197 includes a friction housing 1971. A friction bracket 1972 is fixedly connected to the inner side of the friction housing 1971. A connecting plate 1973 is fixedly connected to the outer side of the friction bracket 1972. A silica gel plate 1974 is fixedly connected to one side of the connecting plate 1973 away from the friction housing 1971. A second spring 1975 is fixedly connected to the inner side of the friction bracket 1972. When the connecting rod 1952 is relieved of extrusion, the spring rebounds. The rapid ejection is likely to cause mechanical wear, thus affecting the service life of the components. By means of the friction between the silica gel plate 1974 and the outer side of the connecting rod 1952, the resistance between the components is increased, thereby achieving the effect of slowing down the sliding speed of the components, reducing the wear between the components, and prolonging the service life of the components. Grooves are formed on the surface of the silica gel plate 1974. By grooving, the deformation performance of the components is increased, thereby further improving the friction and buffering effects. When the silica gel plate 1974 rubs against the surface of the components, it is easy to cause the components to vibrate. The second spring 1975 plays a buffering role to reduce the vibration amplitude of the components and improve the stability of the components.

[0026] Second Embodiment. On the basis of the first embodiment, please refer to Figures 7 to 8 As shown, the processing mechanism 2 includes a blower 21. One side of the outside of the blower 21 is fixedly connected to the outside of the composite housing 11. A ventilation pipe 22 is fixedly connected to the side of the blower 21 away from the composite housing 11. An annular housing 23 is plugged and connected to the side of the ventilation pipe 22 away from the blower 21. A filter plate 24 is fixedly connected to the inner side of the annular housing 23. A chip removal pipe 25 is fixedly connected to the outside of the ventilation pipe 22. A rotating mechanism 26 is fixedly connected to the inner wall of the ventilation pipe 22. By generating wind with the blower 21, the hot air flow inside the composite mechanism 1 is discharged to the outside, thereby achieving the regulation of the temperature and humidity inside the equipment, being beneficial to improving the drying efficiency and the stability of the product quality, ensuring fresh air. Continuous ventilation and air exchange can maintain the freshness of the air inside the oven, provide a good working environment for the operators, reduce the harm of harmful gases to the human body, and guarantee the physical health of the operators. Volatile substances are discharged. During the drying process of the epoxy coil, the solvents and moisture in the coating will volatilize. Ventilation and air exchange can timely discharge the volatile substances from the oven, enabling the solvents and moisture on the surface of the coil to volatilize quickly and evenly, thereby improving the drying quality. The air flow moves towards the filter plate 24 through the ventilation pipe 22. The air flow is filtered by the filter plate 24 to reduce the discharge of harmful substances to the outside and reduce the impact on the human body, optimizing the working environment. After long-term operation, impurities or particles are likely to accumulate on the inner wall of the ventilation pipe 22. The rotating mechanism 26 is driven to rotate by the wind force, so that the rotating mechanism 26 cleans the impurities on the inner wall, and then the impurities are discharged to the outside through the chip removal pipe 25.

[0027] The rotating mechanism 26 includes a fixed frame 261. A connecting shaft 262 is fixedly connected between opposite faces of the fixed frame 261. A rotating column 263 is rotatably connected to the outer side of the connecting shaft 262. A rotating frame 264 is fixedly connected to the outer side of the rotating column 263. A scraping plate 266 is fixedly connected to one side of the rotating frame 264 away from the rotating column 263. A circular paddle 265 is fixedly connected to the groove of the outer part of the rotating frame 264. The circular paddle 265 is arranged on the rotating frame 264. When the air flow flows inside the ventilation pipe 22, it impacts the outer side of the circular paddle 265, causing the air flow to drive the circular paddle 265 to rotate. The circular paddle 265 drives the rotating frame 264 to rotate, so that the scraping plate 266 rubs against the inner wall of the pipe, thereby cleaning the impurities on the inner wall of the pipe, reducing the accumulation of impurities on the inner wall of the pipe, and preventing excessive accumulation of impurities, so as to avoid affecting the air flow effect inside the pipe.

[0028] The third embodiment, on the basis of the first and second embodiments, please refer to Figures 9 to 10 As shown, the cooling mechanism 3 includes a cooling frame base 31. The bottom of the cooling frame base 31 is fixedly connected to the top of the second receiving platform 191. A frame body 32 is fixedly connected to the top of the cooling frame base 31. An electric push rod 33 is fixedly connected to the bottom of the frame body 32. A square pipe 34 is fixedly connected to one side of the outer part of the electric push rod 33 away from the frame body 32. A first port 35 is fixedly connected to one side of the outer part of the square pipe 34. A second port 36 is fixedly connected to the side of the square pipe 34 away from the first port 35. After the coil is dried, during the process of moving towards the winding mechanism 19, the height of the square pipe 34 is adjusted by the electric push rod 33, so as to facilitate the square pipe 34 to fit on the surface of the coil, thereby achieving the effect of cooling the coil and preventing the coil from deforming. The temperature of the dried coil is relatively high. If it is directly wound or processed subsequently, due to the effect of thermal expansion and contraction, the coil may deform, shrink or wrinkle during the cooling process, affecting the flatness and dimensional stability of the coil. Through the cooling treatment, the coil can be shaped at a relatively stable temperature, reducing the possibility of deformation. The cooling liquid enters from the first port 35 and exits from the second port 36, so as to continuously feed the liquid to ensure continuous cooling.

[0029] A drying process for epoxy coil production includes the following steps: Step 1, placement, place the coil on one side of the composite mechanism 1, pass one end of the coil through the roller mechanism 18, set it on the winding mechanism 19, and control the movement and drying of the coil through the winding mechanism 19; Step 2, drying, the coil passes through the inside of the composite housing 11, and the surface of the coil is heated by the heater 13 to achieve the drying operation of the coil; Step 3, ventilation, the treatment mechanism 2 is arranged on both sides of the composite housing 11, and the temperature inside the equipment is adjusted through the treatment mechanism 2 to volatilize substances; Step 4: Cooling. The coil moves towards the winding mechanism 19 and comes into contact with the cooling mechanism 3. The cooling mechanism 3 cools the coil to prevent the coil from deforming.

[0030] During use, the epoxy coil is placed on the receiving rack 17 by the staff. The receiving rack 17 slides on the first slide rail 16 to clamp and carry the coil. One end of the coil is placed on the winding mechanism 19. The motor 196 drives the winding mechanism 19 to rotate, thereby achieving the function of automatically winding the coil. The coil partially passes through the roller mechanism 18 and moves inside the composite housing 11. During the movement, the heater 13 heats the surface of the coil to dry the coil. The coating on the coil surface is dried to cure the coating. The dried coil is convenient for subsequent processing and treatment. When passing through the roller mechanism 18, the roller mechanism 18 carries the coil to keep the coil in a stable state, reducing the contact with the inner wall of the equipment and preventing local airtightness, which may affect the drying effect and efficiency, avoiding incomplete drying, and restricting the movement direction of the coil during winding to prevent the coil from folding during movement, which may affect the drying effect and subsequent use effect. During the heating process of the composite mechanism 1 on the coil, the processing mechanism 2 is arranged on both sides of the composite housing 11. The fan 21 generates wind to discharge the hot air flow inside the composite mechanism 1 to the outside, thereby achieving the regulation of the temperature and humidity inside the equipment, which is beneficial to improving the drying efficiency and the stability of product quality, ensuring fresh air. Continuous ventilation can maintain the freshness of the air inside the oven, provide a good working environment for the operator, reduce the harm of harmful gases to the human body, and protect the health of the operator. Volatile substances are discharged. During the drying process of the epoxy coil, the solvent and moisture in the coating will volatilize. Ventilation can timely discharge the volatile substances from the oven, so that the solvent and moisture on the coil surface can volatilize quickly and evenly, thereby improving the drying quality. During the movement of the coil towards the winding mechanism 19, it comes into contact with the cooling mechanism 3. The cooling mechanism 3 adopts the form of water cooling to achieve the function of cooling the coil and preventing the coil from deforming. The temperature of the dried coil is relatively high. If it is directly wound or subjected to subsequent processing, due to the effect of thermal expansion and contraction, the coil may deform, shrink or wrinkle during the cooling process, affecting the flatness and dimensional stability of the coil. Through the cooling treatment, the coil can be shaped at a relatively stable temperature, reducing the possibility of deformation.
