[0002] Annealing is a metal heat treatment process, which means slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate rate. The purpose is to reduce hardness and improve machinability; reduce residual stress, stabilize size, reduce deformation and crack tendency; refine grains, adjust structure, and eliminate structural defects. To be precise, annealing is a heat treatment process for materials, including metal materials and non-metallic materials. The purpose of annealing new materials is also different from that of traditional metal annealing. Annealing furnace is a kind of equipment for annealing the above materials.
[0003] In the existing annealing furnace, the efficiency of opening and closing the furnace door is low during the process of feeding and discharging metal, resulting in a need to wait for the carrier plate to deliver the material in or out after the furnace door is opened, and then closing the furnace door causes a large heat loss in the furnace, which is not conducive to annealing the next batch of materials.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0018] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.
[0019] A clean annealing furnace, such as Figures 1 to 4 As shown, it includes an annealing furnace body 1, and a loading and unloading device 2 arranged at the feeding port of the annealing furnace body 1, the loading and unloading device 2 is provided with a conveyor belt 3, a transmission plate 4 is slidably provided on the conveyor belt 3, a limiting tooth 5 is provided on the conveying surface of the conveyor belt 3, a rotating gear 6 is provided on the transmission plate 4, the gear and the limiting tooth 5 are meshed with each other, a loading plate 7 is provided on the transmission plate 4, limiting grooves 8 are provided on both sides of the conveyor belt 3, a limiting plate 9 corresponding to the conveyor belt 3 is provided at the bottom end of the transmission plate 4, a horizontally rotating roller 10 is provided on the limiting plate 9, the roller 10 is clamped with the limiting groove 8, two mounting rods 11 are rotatably provided on the transmission plate 4, the rotating gear 6 is fixedly provided at the end of the mounting rod 11, and a motor 12 for driving the mounting plate to rotate is provided on the transmission plate 4.
[0020] In the above embodiment, it should be noted that the motor 12 is an external power source, which drives the transmission plate 4 to slide through the conveyor belt 3, so that the loading plate 7 on the transmission plate 4 can slide back and forth to load and unload materials. At the same time, the rotating gear 6 on the transmission plate 4 cooperates with the limiting teeth 5 on the conveyor belt 3 to achieve the effect of rapid loading and unloading. At the same time, two horizontally rotating rollers 10 fix the transmission plate 4 on the conveyor belt 3 to prevent the transmission plate 4 from tipping over during transportation.
[0021] refer to Figure 3 and Figure 4 As shown: the loading and unloading device 2 is provided with a mounting frame 13, a mounting shaft 14 is provided on the mounting frame 13, a transmission gear is provided at the end of the mounting shaft 14, a transmission tooth meshing with the transmission gear is provided on the inner wall of the conveyor belt 3, a driving gear 15 is provided at one end of the motor 12, a driven gear 16 is provided on the mounting shaft 14, a tightening gear 17 is slidably provided on the mounting frame 13, the driving gear 15, the driven gear 16 and the tightening gear 17 are connected by a transmission belt 18, and an elastic member 19 is provided on the mounting frame 13 to push the tightening gear 17 away from the driven gear 16.
[0022] In the above embodiment, the driving gear 15, the driven gear 16 and the tightening gear 17 are connected by the transmission belt 18. When the motor 12 is working, the motor 12 drives the rotating gear 6 to rotate while driving the driving gear 15, so that the driving gear 15 drives the driven gear 16 and the tightening gear 17 to rotate through the transmission belt 18, so that when the motor 12 is working, it drives the rotating gear 6 to rotate and move on the conveyor belt 3, and at the same time, the conveyor belt 3 can transport the transmission plate 4. Since the motor 12 and the driving gear 15 are in a moving state relative to the driven gear 16, the elastic member 19 pushes the tightening gear 17 to apply tension to the transmission belt 18, thereby achieving the effect of the conveyor belt 3 and the rotating gear 6 rotating simultaneously and in the same direction.
[0023] refer to Figure 4 As shown: the mounting frame 13 is provided with a slide groove, a sliding plate 20 is arranged in the slide groove, the tightening gear 17 is rotatably arranged on the sliding plate 20, a limiting rod 21 is arranged at the end of the sliding plate 20, a baffle corresponding to the limiting rod 21 is arranged on the mounting frame 13, a limiting hole corresponding to the limiting rod 21 is arranged on the baffle, and the elastic member 19 is a spring, and the spring is sleeved on the limiting rod 21.
[0024] In the above embodiment, the setting of the slide groove limits the sliding direction of the tightening gear 17, and the setting of the limit rod 21 prevents the elastic member 19 from exerting a force other than the thrust on the tightening gear 17, thereby ensuring the tension of the transmission belt 18.
[0025] Working principle:
[0026] When loading and unloading is required, the motor 12 is energized, and the motor 12 drives the rotating gear 6 to rotate. The rotating gear 6 moves on the limiting tooth 5 of the conveyor belt 3. At the same time, the motor 12 drives the driving gear 15 to rotate. The driving gear 15 drives the driven gear 16 and the tightening gear 17 to rotate through the transmission belt 18. The driven gear 16 drives the transmission gear to rotate through the mounting shaft 14, thereby making the conveyor belt 3 work. At the same time, the elastic member 19 will push the tightening gear 17 to slide, ensuring the tension of the transmission belt 18, so that the conveyor belt 3 works when the rotating gear 6 rotates, thereby achieving the effect of double transportation, speeding up the up and down chat, and reducing the heat damage of the equipment when opening and closing the door leaf.
[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
