[0002] Drying ovens are used to dry materials. As key equipment for achieving batch and efficient drying, their performance directly affects production efficiency and product quality. Traditional drying ovens often suffer from problems such as unreasonable workstation layout and low material conveying efficiency. For example, using a single rack to carry materials cannot fully utilize the oven space, resulting in fewer drying batches and limited capacity. Some drying ovens have complex material conveying devices with poor operational stability, making them prone to failure during long-term continuous operation. Furthermore, it is difficult to keep the material stable during conveying, affecting the uniformity of the drying effect. In addition, traditional drying ovens have a low degree of automation in the feeding and discharging stages, relying on manual operation, which not only increases labor costs but also poses safety hazards, and makes it difficult to achieve precise loading and unloading of materials and continuous production.

[0016] like Figure 1-3As shown, the multi-station drying oven includes a furnace body 1 and several hanging racks 2. One end of the furnace body 1 has a feed inlet 3 connecting to the interior of the furnace body 1, and the other end has a discharge outlet 4 connecting to the interior of the furnace body 1. Both the feed inlet 3 and the discharge outlet 4 are covered with furnace covers 5. Inside the furnace body 1 are heaters 6 and a conveyor belt. The conveyor belt consists of several parallel annular chains 7, which are driven synchronously by a drive mechanism. Several pallets 8 are fixedly connected to the annular chains 7, and each pallet 8 has a slot 9. The hanging racks 2 include a main rod 10, which is fixedly connected to several insert rods 11. Several hanging rods 12 are fixedly connected to both sides of the main rod 10. The insert rods 11 correspond to the pallets 8 and are inserted into the slots 9 of the corresponding pallets 8. Workers place the hanging racks 2 with the materials attached into the furnace body 1 through the feed inlet 3, and the insertion rods 11 cooperate with the slots 9 on the pallets 8 to stably connect the hanging racks 2 to the conveyor belt. The conveyor belt moves gradually until all the racks 2 are in place, and the furnace cover 5 is closed. Then the heater 6 is started to heat and dry the material on the racks 2. After the material is dried, the racks 2 on the conveyor belt are removed one by one from the discharge port 4. During the drying process, the conveyor belt can move back and forth for a distance to improve the drying effect of the material.

[0017] Furthermore, the drive mechanism includes a drive motor, a drive shaft 32, and a driven shaft 13. Several gears 14 are fixedly connected to the drive shaft 32 and the driven shaft 13, respectively. The gears 14 mesh with the annular chains 7. The drive motor drives the drive shaft 32 to rotate. The drive motor driving the drive shaft 32 to rotate causes all the annular chains 7 to rotate synchronously, thus conveying the hanger 2. There are at least two annular chains 7. The insert rods 11 on the hanger 2 correspond one-to-one with the pallets 8 and are inserted into the corresponding slots 9. To improve the stability of the connection between the hanger 2 and the conveyor belt, the insert rods 11 on the hanger 2 can be arranged in multiple rows, forming multi-point support.

[0018] Furthermore, the drive shaft 32 and the driven shaft 13 are rotatably mounted on the furnace body 1 and located outside the furnace body 1, and the furnace body 1 has side openings 15 on both sides for the annular chain 7 to extend out.

[0019] Furthermore, it also includes a front lifting and supporting mechanism 17 and a rear lifting and supporting mechanism 18. The front lifting and supporting mechanism 17 and the rear lifting and supporting mechanism 18 have the same structure. The front lifting and supporting mechanism 17 includes a left lifting rod 16, a right lifting rod 19, a left lifting synchronous chain 20, a right lifting synchronous chain 21, an upper rotating shaft 22, and a lower rotating shaft 23. The upper rotating shaft 22 and the lower rotating shaft 23 are rotatably mounted on the furnace body 1. The two ends of the upper rotating shaft 22 are fixedly connected to the left synchronous wheel 24 and the right synchronous wheel 25, respectively. The two ends of the lower rotating shaft 23 are fixedly connected to the left synchronous wheel 24 and the right synchronous wheel 25, respectively. The left synchronous pulley 24 and the right synchronous pulley 25 are fixedly connected. The left synchronous pulley 24 meshes with the left lifting synchronous chain 20, and the right synchronous pulley 25 meshes with the right lifting synchronous chain 21. The left lifting rod 16 is fixedly connected to the left lifting synchronous chain 20, and the right lifting rod 19 is fixedly connected to the right lifting synchronous chain 21. The lower rotating shaft 23 is driven to rotate by a lifting motor. The upper ends of the left lifting rod 16 and the right lifting rod 19 are respectively provided with lifting grooves 26. The left lifting rod 16 and the right lifting rod 19 are located below the feed inlet 3 or below the discharge outlet 4. During the feeding process, the left lifting rod 16 and the right lifting rod 19 in the front lifting lifting mechanism 17 rise synchronously. The worker puts the hanging rack 2 with the material on it into the furnace body 1 from the feed inlet 3, and the two sides of the hanging rack 2 are respectively placed into the lifting grooves 26. The left lifting rod 16 and right lifting rod 19 descend synchronously, bringing the hanging frame 2 closer to the conveyor belt. Finally, the insertion rod 11 on the hanging frame 2 is inserted into the corresponding slot 9, and the left lifting rod 16 and right lifting rod 19 continue to descend a certain height. The conveyor belt moves a certain distance, and the left lifting rod 16 and right lifting rod 19 rise, supporting the other hanging frame 2. After drying, the rear lifting and supporting mechanism 18 uses the same working principle to lift the hanging frames 2 one by one to the discharge port 4.

[0020] Furthermore, a detection shaft 27 is provided below the discharge port 4, located above one of the annular chains 7. A through hole 28 is provided on the furnace body 1. One end of the detection shaft 27 is located inside the furnace body 1, and the other end moves through the through hole 28 and is subsequently fitted with a limit plate 29 and a spring 30. The limit plate 29 is fixedly connected to the detection shaft 27, and the spring 30 is sleeved on the detection shaft 27. A baffle 31 is fixedly connected to the furnace body 1, and the spring 30 is sandwiched between the baffle 31 and the limit plate 29. The diameter of the limit plate 29 is larger than the diameter of the through hole 28. The conveyor belt stops moving after the detection shaft 27 touches the hanger 2 on the conveyor belt. A contact switch is installed on the detection shaft 27 to sense the hanger 2. The contact switch is used to control the start of the drive motor to prevent excessive movement of the conveyor belt from causing the hanger 2 to collide with the furnace body 1.

[0021] Furthermore, a heat exchanger 32 is installed inside the furnace body 1. The heat exchanger 32 can be a heat-conducting coil as used in existing technology. A heat-conducting liquid is circulated in the heat-conducting coil, and the temperature inside the furnace body 1 is precisely controlled by controlling the flow rate of the heat-conducting liquid. The heat exchanger 32 can also remove excess heat from the furnace body 1 for recycling.

[0022] It is worth mentioning that the technical features of the motor, electric heater, heat exchanger and other components involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0023] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort.
