Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0024] like Figure 1-5 As shown, a welding rod drying device comprises a first conveyor belt 1, a second conveyor belt 2, a hot air box 3, a third conveyor belt 5, a fourth conveyor belt 6, a cold air box 7 and a bottom conveyor belt 8 which are arranged in sequence from top to bottom, a transfer roller 10 is provided between the tail end of the first conveyor belt 1 and the beginning end of the second conveyor belt 2, an arc guide plate 4 is provided between the tail end of the second conveyor belt 2 and the beginning end of the third conveyor belt 5, a transfer roller is provided between the tail end of the third conveyor belt 5 and the beginning end of the fourth conveyor belt 6, an arc guide plate 4 is provided between the tail end of the fourth conveyor belt 6 and the bottom conveyor belt 8, a plurality of ventilation holes 16 are evenly distributed on the upper and lower surfaces of the hot air box 3 and the cold air box 7, and the hot air box 3 and the cold air box 7 are respectively connected to an air source through an air pipe 12;

[0025] It also includes a frame, which is not shown in the attached drawings. It is just an ordinary metal frame and is not the subject of this case. The first conveyor belt 1, the second conveyor belt 2, the hot air box 3, the third conveyor belt 5, the fourth conveyor belt 6, the cold air box 7, the transfer roller 10, the bottom conveyor belt 8 and the arc guide plate 4 are all installed in the frame. The first conveyor belt 1, the second conveyor belt 2, the third conveyor belt 5 and the fourth conveyor belt 6 are all mesh conveyor belts;

[0026] The transfer roller comprises a roller body and support rods 9 fixed at both ends of the roller body 10. The end of each support rod 9 is hinged to the frame through a bearing. Two circles of guide grooves 11 are fixed on the surface of the roller body 10, and each circle of guide grooves 11 is provided with 8 grooves.

[0027] Insertion rods 14 are symmetrically fixed at both ends of the arc guide plate 4. Two insertion rods 14 are fixed at each end of the arc guide plate 4. The two insertion rods 14 at the same end are vertically aligned and have pin holes aligned therein. The positioning pins 13 are inserted into the corresponding pin holes of the two insertion rods 14.

[0028] The guide groove 11 is in an L-shaped structure.

[0029] The hot air box 3 has screws 15 detachably screwed on both sides, with two screws 15 connected to each side, and the screws 15 are screwed and connected to the frame, and the hot air box 3 and the cold air box 7 have the same structure. The screws 15 facilitate the disassembly and assembly of the hot air box 3 and the cold air box 7 on the frame.

[0030] When in use, the conveyor belt drives the welding rod to move from top to bottom. The welding rod coming towards the transfer roller naturally falls into the two guide grooves 11 horizontally. Due to its own gravity, the transfer roller rotates clockwise, and the welding rod is brought from the first conveyor belt 1 to the second conveyor belt 2. When the welding rod moves to the tail end of the second conveyor belt 2, it naturally falls onto the arc guide plate 4. The arc guide plate 4 brings the welding rod to the third conveyor belt 5 and continues to be transported. While transporting, the upper and lower sides of the hot air box 3 blow air to dry the welding rod. The upper and lower sides of the cold air box 7 blow air to quickly cool the welding rod. Finally, the welding rod falls onto the bottom conveyor belt 8 and is transported to the next process.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
