DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5The utility model provides a technical solution: a medium-frequency induction heating furnace with uniform heating, comprising: an operating base 1, a mounting frame 2, a heating furnace body 3, a guide bin 4, a first guide roller 5, a second guide roller 6, a third guide roller 7, an electric push rod 8, a rotating roller 9, a synchronous pulley 10, a first motor 11, a belt 12, a rack 13, a rotating rod 14, a gear 15, a cleaning roller 16, a bidirectional threaded rod 178, and a second motor 18.

[0028] First, as attached Figure 1 and attached Figure 4 As shown in the figure, when the medium frequency induction heating furnace is used to process the material, the material is first placed between the rotating wheels at the front and rear ends of the rotating roller 9, and then the operating base 1 is started, so that the conveying mechanism on the operating base 1 drives the material to pass through the guide bin 4, and at the same time, the material enters the interior of the heating furnace body 3, and then the electric push rod 8 is started, so that the output end of the electric push rod 8 drives the third guide roller 7 to slide on the side wall of the guide bin 4, and at the same time, the third guide roller 7 is slidably connected with the second guide roller 6 in a "U"-shaped structure, so that the third guide roller 7 drives the second guide roller 6 to slide on the side wall of the guide bin 4, and at the same time The third guide roller 7 drives the second guide roller 6 to slide in the opposite direction, and then the first guide roller 5 is arranged in a corresponding state with the second guide roller 6 and the third guide roller 7, so that the third guide roller 7 drives the second guide roller 6 to approach the first guide roller 5, so that the first guide roller 5, the second guide roller 6 and the third guide roller 7 fix the material. At the same time, when the material is moved by the conveying mechanism on the operating base 1, the material contacts the rollers on the first guide roller 5, the second guide roller 6 and the third guide roller 7, so that the movement of the material drives the rollers on the first guide roller 5, the second guide roller 6 and the third guide roller 7 to rotate.

[0029] As attached Figure 1 , Attachment Figure 3 and attached Figure 5 As shown in the figure, when the conveying mechanism on the operating base 1 drives the material to move inside the heating furnace body 3, the first motor 11 at the bottom of the mounting frame 2 can be started. Since the synchronous pulley 10 on the output end of the first motor 11 is connected to the synchronous pulley 10 on the rotating roller 9 through the belt 12, the first motor 11 drives the rotating wheel on the rotating roller 9 to rotate through the belt 12, thereby driving the rotation of the rotating wheel on the rotating roller 9 to drive the rotation of the material, so that the material rotates inside the heating furnace body 3, and at the same time, the material is transported through the right guide bin 4 in the mounting frame 2 through the conveying mechanism on the operating base 1, and the material is also brought into contact with the rotating wheel of the right rotating roller 9 in the operating base 1, thereby ensuring that the material is heated as a whole, thereby improving the product processing quality and performance.

[0030] As attached Figure 1 and attached Figure 2 As shown in the figure, when the material is heated, the debris on the material falls off, and the debris falls onto the inner bottom of the heating furnace body 3 or the mesh plate in the middle of the heating furnace body 3, and then the second motor 18 can be started, so that the output end of the second motor 18 drives the bidirectional threaded rod 17 to rotate inside the heating furnace body 3, and then the bidirectional threaded rod 17 is connected to the middle position of the rotating rod 14, and the inner side wall of the middle position of the rotating rod 14 is connected to the bidirectional threaded rod 17 through threads, so that the bidirectional threaded rod 17 drives the rotating rod 14 to slide inside the heating furnace body 3, and also makes the bidirectional threaded rod 17 The threaded rod 17 drives the cleaning roller 16 to slide in the opposite direction through the rotating rod 14. When the bidirectional threaded rod 17 drives the rotating rod 14 to slide inside the heating furnace body 3, the gear 15 on the rod body of the rotating rod 14 engages with the rack 13, so that the gear 15 drives the cleaning roller 16 to rotate through the rotating rod 14. Since the cleaning roller 16 is in contact with the inner bottom of the heating furnace body 3 and the mesh plate at the middle position inside the heating furnace body 3, the cleaning roller 16 can tilt the debris on the mesh plate to the inner bottom of the heating furnace body 3, and at the same time, the cleaning of the inner bottom of the heating furnace body 3 is concentrated together, thereby facilitating subsequent cleaning.
