[0022] 1.

[0023] 2. In the present invention, the welding rod is extruded and formed by an extrusion device. The extrusion process also utilizes the situation that the welding rod automatically flips due to uneven weight, so that each surface of the welding rod is squeezed. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] See also Figure 1-Figure 4The present invention provides a welding rod powder coating machine with a fixing function, wherein a welding rod positioning mechanism 1 comprises an end plate 101, a welding rod fixing strip plate 102, a V-groove 103, a support frame 104, an inlet oblique rod 105 and an outlet oblique rod 106, welding rod fixing strip plates 102 are fixedly installed at both ends of the end plate 101, V-grooves 103 are arranged at intervals on the welding rod fixing strip plates 102, a support frame 104 is fixedly installed below the end plate 101, an inlet oblique rod 105 fixedly connected to the V-groove 103 is arranged above the end plate 101, an outlet oblique rod 106 is fixedly installed at the top of the end of the welding rod fixing strip plate 102, a welding rod pushing mechanism 2 is arranged outside the end plate 101, the welding rod pushing mechanism 2 comprises a bar 201, a vertical bar 202, a welding rod groove 203 and a connecting frame 204, vertical bars 202 are arranged at intervals on the bar 201, welding rod grooves 203 are formed between the two bar 20 1, a connecting frame 204 is fixedly connected between the ends of the connecting frame 204, a first cylinder 3 is fixedly installed on the outer side of the connecting frame 204, and a second cylinder 4 is fixedly connected to the lower part of the first cylinder 3, a welding powder spraying device 5 is arranged above the welding rod positioning mechanism 1, extension plates 6 are fixedly installed on both sides of the spraying surface of the welding powder spraying device 5, and a protective skin 7 is fixedly installed on the outer side of the extension plate 6, and the protective skin 7 covers the welding rod pushing mechanism 2, and a recovery conveyor belt 9 corresponding to the welding powder spraying device 5 is arranged below the welding rod positioning mechanism 1, an extrusion device 8 is arranged at the end of the welding rod fixing strip plate 102 located on the outer side of the welding powder spraying device 5, and the extrusion device 8 is symmetrically arranged above and below the welding rod fixing strip plate 102, and the extrusion device 8 includes a third cylinder 801, a pressing plate 802 and an arc groove 803, and the pressing plate 802 is fixedly installed on the inner rod end of the third cylinder 801, and the arc groove 803 is symmetrically opened on the lower side of the pressing plate 802.

[0033] Specifically, the opening width of the V-groove 103 is the same as the width of the electrode groove 203, and the width of the vertical rod 202 is the same as the spacing length between the openings of the V-groove 103, which is convenient for moving the welding core. After being put down, the spacing is the same and the position is stable.

[0034] Specifically, Figure 1 As shown, the connecting frame 204 is arranged at the inner side of the supporting frame 104 to facilitate the forward movement and resetting of the electrode advancing mechanism 2.

[0035] Specifically, the protective skin 7 is made of rubber material and is easy to clean. A distance is left between the protective skin 7 and the bar 201 to reserve space for the welding core end to extend.

[0036] Specifically, the length of the pressing plate 802 is the same as the spacing length between the electrode fixing strips 102, and the axis of the arc groove 803 is arranged corresponding to the lowest point of the V groove 103 to press all the welding powder.

[0037] Working principle:

[0038] The welding core rolls down from the inlet inclined rod 105 and falls to the first V-groove 103 position of the welding rod fixing strip plate 102, then the second cylinder 4 extends, the welding rod pushing mechanism 2 rises, the first cylinder 3 pushes and contracts, and moves the welding rod pushing mechanism 2 forward one grid, that is, the welding rod groove 203 at the end moves to the second V-groove 103 position, then the second cylinder 4 contracts, and all welding cores move forward one grid;

[0039] During this process, the welding powder spraying device 5 sprays welding powder onto the welding core, and the two ends of the welding core extend out of the welding rod fixing strip plate 102 by a length of five or six centimeters. The welding core section on the inner side of the welding rod fixing strip plate 102 is coated with welding powder. As the weight of the coated welding powder increases, the welding core is at the V-groove 103. Because the welding core is heavy on the top and light on the bottom, it automatically rolls and flips. The welding core surface that is not coated with welding powder flips upward and is coated with welding powder. Then, the welding core flips down again due to the uneven weight of the upper and lower parts. In this way, when the welding core coated with welding powder moves to the extrusion device 8, the welding powder has been thickly coated. The third cylinder 801 extends, and the two pressing plates 802 press the welding powder tightly. Because the arc groove 803 at the first position is pressed down, the welding rod is unevenly coated with powder. When it falls to the arc groove 803 at the rear position, the welding rod automatically flips. After the arc groove 803 at the rear position is pressed down, the welding rod body is completely pressed down, and the welding rod is formed.

[0040] The formed welding rod moves to the position of the output inclined rod 106 and is guided to slide out;

[0041] During the process of spraying the welding powder, the fallen welding powder is transported out through the recovery conveyor belt 9 to be recovered and reused.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
