[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 3As shown, the utility model provides an energy-saving and environmentally friendly tunnel baking line, which includes a pair of side panels 1, the side walls of the pair of side panels 1 are commonly fixed with a bottom plate 11, the side walls of the pair of side panels 1 are rotatably connected to a conveyor belt 12, the top of the side panel 1 is fixed with a baking cover 13, the side walls of the baking cover 13 are fixed with a pair of hydraulic cylinders 14, the pair of hydraulic cylinders 14 are symmetrically arranged, the ends of the pair of hydraulic cylinders 14 are commonly fixed with a fixing frame 15, the inner side wall of the fixing frame 15 is fixed with an electric heating pipe 16, when working, when the material is baked, the conveyor belt 12 is started to rotate in a cycle and then the material is placed on the conveyor belt 12, at this time the electric heating pipe 16 is energized and heated, and then the height of the electric heating pipe 16 can be adjusted according to the height of the material, and the fixed frame 15 can be driven to lower or rise by starting the hydraulic cylinders 14 on both sides to stretch or contract, thereby driving the internal electric heating pipe 16 to approach or move away from the material on the conveyor belt 12, and the hydraulic cylinder 14 is stopped when the electric heating pipe 16 approaches the top of the material.

[0022] By providing a hydraulic cylinder 14 to connect the fixing frame 15 and the electric heating tube 16, the distance between the electric heating tube 16 and the material can be easily adjusted so that the electric heating tube 16 is close to the material for baking, thereby improving the baking effect of materials at different heights and reducing the situation where the distance between the electric heating tube 16 and the material is too large, resulting in heat loss and causing a slow drying speed.

[0023] like Figures 2 to 4 As shown, a pair of fans 2 are fixedly connected to the top of the baking hood 13, and a pair of air inlets 21 are opened on the top of the baking hood 13. The fans 2 are arranged corresponding to the air inlets 21. The inner wall of the air inlet 21 is fixedly connected to a fixed frame 22, and the inner wall of the fixed frame 22 is fixedly connected to a plurality of guide plates 23. The plurality of guide plates 23 are in a symmetrical inclined structure on both sides. When working, the fans 2 are started to drive the airflow from the air inlet 21 to the electric heating tube 16, and then from the electric heating tube 16 to the surface of the conveyor belt 12. When the airflow passes through the electric heating tube 16, it will be heated, and then blown to the material on the conveyor belt 12. When the airflow passes through the guide plate 23, the guide plate 23 will divert the airflow to increase the blowing range of the airflow.

[0024] By setting up the fan 2 in conjunction with the electric heating tube 16, air can be blown onto the material to increase the speed at which heat reaches the material. At the same time, the guide plate 23 diverts the airflow, which can increase the flow range of the airflow and the contact surface with the material, thereby improving the baking effect of the material.

[0025] like Figure 1 and Figure 5As shown, a square groove 3 is provided on the side wall of the side plate 1, a fixed plate 31 is fixedly connected to the top of the bottom plate 11, a scraper 32 is fixedly connected to the top of the fixed plate 31, the top of the scraper 32 is in contact with the conveyor belt 12, and a guide plate 33 is fixedly connected to the side wall of the scraper 32. The guide plate 33 has an inclined structure. During operation, when the material is transported on the conveyor belt 12, there will be debris and other impurities adhering to the surface of the conveyor belt 12. At this time, the scraper 32 will scrape the surface of the conveyor belt 12 from the bottom, clean up the adhered debris and then drop it from the guide plate 33.

[0026] The scraper 32 can be provided to scrape the surface of the conveyor belt 12 to reduce the situation where debris generated during the conveying of materials adheres to the surface of the conveyor belt 12 and causes contamination of the next batch of materials.

[0027] like Figure 5 As shown, a collecting box 4 is placed on the top of the fixed plate 31, and the collecting box 4 is arranged near the outlet of the guide plate 33. A fixing block 41 is fixed to the bottom of the collecting box 4, and a slide groove 42 is provided on the top of the fixed plate 31. The fixing block 41 slides with the slide groove 42. During operation, when the impurities adhering to the conveyor belt 12 are scraped off by the scraper 32, they will fall from the guide plate 33 into the collecting box 4 for collection. When the collection is completed, the collecting box 4 and the fixing block 41 are pulled out, and after the collected impurities are poured out, the fixing block 41 is aligned with the slide groove 42 and the collecting box 4 is reset.

[0028] By providing the collecting box 4, the fixing block 41 and the chute 42, it is convenient to collect the impurities scraped off the conveyor belt 12 by the scraper 32, so as to reduce the accumulation of impurities at the bottom of the conveyor belt 12, which makes it difficult to clean and causes pollution.

[0029] like Figure 5 As shown, a sponge strip 5 is fixedly connected to the top of the fixed plate 31, the sponge strip 5 is in contact with the conveyor belt 12, and a collecting tray 51 is fixedly connected to the side wall of the sponge strip 5. During operation, after the scraper 32 scrapes the surface of the conveyor belt 12, as the conveyor belt 12 continues to rotate, the sponge strip 5 will wipe the surface of the conveyor belt 12 and wipe off the remaining smaller impurities. At this time, the collecting tray 51 will collect the wiped-off smaller impurities. After the collection is completed, the impurities in the collecting tray 51 can be cleaned up.

[0030] By setting up the sponge strip 5 and the collection tray 51, the surface of the conveyor belt 12 can be wiped to reduce the small debris and impurities remaining on the surface of the conveyor belt 12, which may cause pollution. The scraping effect of the scraper 32 can be improved to improve the cleaning effect of the conveyor belt 12.

[0031] like Figures 1 to 2As shown, a reflective film 6 is fixed to the inner wall of the baking cover 13, and the reflective film 6 is set to cover the interior of the baking cover 13. During operation, when the electric heating tube 16 generates heat, the heat will not only radiate to the material below, but also radiate to the top and the surroundings. At this time, the heat radiated to the top and the surroundings will be reflected inward by the reflective film 6 on the inner wall of the baking cover 13.

[0032] By providing the reflective film 6 , the diffused heat can be reflected inwards, so as to reduce the waste of heat caused by radiation to the surroundings, thereby improving the utilization effect of heat.

[0033] like Figure 3 As shown, a filter screen 7 is fixedly connected to the bottom of the fixing frame 15. During operation, when the air flow passes through the electric heating tube 16 and blows toward the material, it will be filtered through the filter screen 7 to filter out dust and impurities in the air flow.

[0034] The filter 7 can be provided to filter the airflow, so as to reduce the dust and impurities in the airflow from being blown onto the material, thereby contaminating the material.

[0035] When the material is put on the conveyor belt 12, the electric heating tube 16 is powered on to generate heat, and then the height of the electric heating tube 16 can be adjusted according to the height of the material. The hydraulic cylinders 14 on both sides can be stretched or contracted to drive the fixing frame 15 to be lowered or raised. At this time, the internal electric heating tube 16 can be driven to move closer to or away from the material on the conveyor belt 12. When the electric heating tube 16 is close to the top of the material, the hydraulic cylinder 14 is stopped, and the fan 2 is started to drive the air flow from the air inlet 21 to the electric heating tube 16, and then from the electric heating tube 16 to the surface of the conveyor belt 12. When the air flow passes through the electric heating tube 16, it will be heated and then blown to the material on the conveyor belt 12. When the air flow passes through the guide plate 23, the guide plate 23 will divert the air flow and increase the blowing range of the air flow. When the material is transported on the conveyor belt 12, there will be impurities such as debris adhering to the surface of the conveyor belt 12. At this time, the scraper 32 will clean the surface of the conveyor belt 12 from the bottom. The scraper 32 scrapes the surface of the conveyor belt 12, cleans the adhered debris and then drops it from the guide plate 33. When the impurities adhered to the conveyor belt 12 are scraped off by the scraper 32, they will fall from the guide plate 33 into the collection box 4 for collection. When the collection is completed, the collection box 4 and the fixed block 41 are pulled out, and after the collected impurities are poured out, the fixed block 41 is aligned with the chute 42 and the collection box 4 is reset. After the scraper 32 scrapes the surface of the conveyor belt 12, the sponge strip 5 will wipe the surface of the conveyor belt 12 as the conveyor belt 12 continues to rotate. , and wipe off the remaining smaller impurities. At this time, the collection tray 51 will collect the wiped-off smaller impurities. After the collection is completed, the impurities in the collection tray 51 can be cleaned up. When the electric heating tube 16 heats up, the heat will not only radiate to the material below, but also radiate to the top and the surroundings. At this time, the heat radiated to the top and the surroundings will be reflected inward by the reflective film 6 on the inner wall of the baking cover 13. When the air flow passes through the electric heating tube 16 and blows towards the material, it will be filtered through the filter 7 to filter out dust and impurities in the air flow.
