The cover 2 is disposed at one end of the barrel body 1, and the cover 2 is used for sealing the open ends of the inner cavity 110 and the outer cavity 120, so that when the welding rod barrel is in a closed state, the welding rod is sealed in the inner cavity 110 or the outer cavity 120 by closing the cover 2. A first communication port 111 is formed in the side wall of the first barrel 11, and the first communication port 111 communicates with the inner cavity 110 and the outer cavity 120, so that the welding rod in the inner cavity 110 can enter the outer cavity 120 through the first communication port 111. Be provided with on the outer wall of second barrel 12 and get a groove 13, get a groove 13 and outer cavity 120 intercommunication to make the welding rod in the outer cavity 120 can get into and get a groove 13 in, get a groove 13 and be provided with and be used for pressing from both sides getting a mouth 130 of getting the welding rod, get a mouth 130 and be located the top of getting a groove 13, during welding operation, the welder gets the welding rod use from getting a mouth 130 clamp. The size of the extraction opening 130 is flexibly set according to the use condition of the welding rod, and preferably, the extraction opening 130 can be simultaneously penetrated by 3 to 5 welding rods. The base 10 is provided with a first heating member 14 and a second heating member 15, the first heating member 14 is arranged corresponding to the inner cavity 110, and the first heating member 14 is used for heating the inner cavity 110 to bake the welding rod in the inner cavity 110. The second heating member 15 is disposed corresponding to the outer cavity 120, and the second heating member 15 is used for heating the outer cavity 120 to bake the welding rod in the outer cavity 120. The heating temperature of the first heating member 14 is higher than that of the second heating member 15. It can be understood that the heating temperature of the first heating element 14 is higher than that of the second heating element 15, so that the temperature in the inner cavity 110 is higher than that in the outer cavity 120, thereby being beneficial to avoiding the thermal influence of high temperature on the second cylinder 12 and avoiding the deformation and damage of the second cylinder 12. The purpose of baking the electrode is to heat the electrode to remove the moisture from the electrode, so that the electrode needs to be heated to above 100 ℃ during baking. In this embodiment, the heating temperature T1 of the first heating member 14 is greater than 100 ℃, and the heating temperature T2 of the second heating member 15 is less than 100 ℃. It is also understood that the interior of the can is divided into a high-temperature zone for direct baking and a low-temperature zone for continuous heat preservation. During welding operation, a part of the welding rod can be placed in the inner cavity 110, and the first heating member 14 rapidly heats the welding rod in the inner cavity 110 to a temperature above 100 ℃. After transferring the baked electrode into the outer chamber 120 and continuing to place the unbaked electrode into the inner chamber 110, the lid 2 is closed. The welder tilts the welding rod barrel to enable the welding rod in the outer cavity 120 to enter the workpiece taking groove 13, and the welder clamps the welding rod from the workpiece taking opening 130 for use. While the welder performs the welding operation, the first heating element 14 continues to bake the welding rod in the inner cavity 110, i.e., the welding and baking are performed simultaneously, so as to reduce the waiting time of the welder and further improve the operation efficiency. After the welding rod in the outer cavity 120 is used, the welding rod barrel is inclined, so that the welding rod in the inner cavity 110 enters the outer cavity 120 through the first communicating port 111. Because the welder directly gets the welding rod from getting a mouthful 130 clamp for the cylinder cover 2 only has the on-off operation when packing into the welding rod, is favorable to reducing the switching frequency of cylinder cover 2, avoids cylinder cover 2 to warp the damage because of frequent switch, is favorable to prolonging the life of a welding rod section of thick bamboo.

Specifically, in order to avoid the heat energy loss of a welding rod barrel, the inside of the second barrel 12 is clamped with a heat insulation layer to block the heat energy in the outer cavity 120 from being conducted to the outside, so that the heat insulation effect is improved, and meanwhile, scalding to welders is avoided. The second cylinder 12 is made of a composite material, the second cylinder 12 has a three-layer structure, the inner layer structure and the outer layer structure of the second cylinder have good mechanical strength, and the inner layer structure has thermal conductivity, so that heat energy generated by the second heating element 15 is rapidly conducted to the whole outer cavity 120. The middle layer structure is a heat insulation layer, and the main operation of the middle layer structure is heat insulation, so that the heat energy consumption is reduced.

Specifically, the walls of the inner cavity 110 and the outer cavity 120 are coated with a heat conductive layer. The heat conducting layer is a heat conducting coating and is used for promoting that the heat energy generated by the first heating element 14 and the second heating element 15 can be rapidly conducted to the whole inner cavity 110 and the whole outer cavity 120 respectively, and the heating efficiency of the welding rod is ensured.

Specifically, a second communicating opening 121 is formed in the second cylinder 12, the outer cavity 120 is communicated with the workpiece taking groove 13 through the second communicating opening 121, and a welding rod in the outer cavity 120 can enter the workpiece taking groove 13 through the second communicating opening 121. The first communicating opening 111 and the second communicating opening 121 are opposite, so that welding rods in the inner cavity 110 can sequentially pass through the first communicating opening 111, the outer cavity 120 and the second communicating opening 121 to directly enter the taking groove 13, and the welding rod taking device is convenient to use.

Specifically, the pickup groove 13 protrudes outward from the side wall of the second cylinder 12, and one side of the pickup groove 13 facing the second cylinder 12 is communicated with the outer cavity 120, that is, one side of the pickup groove 13 facing the second cylinder 12 is overlapped with the second communication port 121. The length of the second communicating opening 121 is larger than the depth of the workpiece taking groove 13, the length of the second communicating opening 121 is matched with the length of the welding rod, and when the barrel body 1 inclines, the welding rod in the outer cavity 120 falls into the workpiece taking groove 13. The depth of the picking groove 13 is smaller than the length of the welding rod, and after the welding rod enters the picking groove 13, the top end of the welding rod can pass through the picking opening 130 and extend to the outside of the picking groove 13. It will be appreciated that the tip of the electrode extends outside of the pick-up groove 13 to facilitate the use of the electrode by the welder with a welding jaw. In this embodiment, one side of the pickup groove 13 departing from the second cylinder 12 forms an included angle with the second cylinder 12. Get a side slope setting that groove 13 deviates from second barrel 12, get a bottom to the top of groove 13 promptly, get a distance that groove 13 deviates from a side of second barrel 12 to second barrel 12 and increase in proper order. So that the welding rod in the outer cavity 120 can be smoothly poured into the workpiece taking groove 13 when the barrel body 1 is poured. Meanwhile, when the barrel body 1 is restored to the upright posture, the welding rod is still obliquely placed in the workpiece taking groove 13, and the welding rod is prevented from returning to the outer cavity 120 from the workpiece taking groove 13.

In the closed state, the cover 2 is fastened to the open end of the barrel 1, and the cover 22 can close the open ends of the inner cavity 110 and the outer cavity 120. By elastically connecting the cover plate 22 and the cover body 21, it is advantageous to improve the sealing property to the two cavities. When the cover plate 22 is heated to expand or deform in the baking process, stress can be released through the spring 23, so that the phenomenon that the cylinder cover 2 deforms to cause abnormal opening and closing due to heating is avoided, and the service life of the welding rod cylinder is further ensured.

Specifically, the heat insulating layer is filled between the cover body 21 and the cover plate 22. The thermal insulation layer is used for preventing heat energy from being conducted to the cover body 21, and therefore deformation and damage of the cover body 21 caused by heating are avoided.

Specifically, a plurality of reinforcing rings 16 are arranged at intervals on the outer wall of the second cylinder 12. The reinforcing ring 16 is annular, the reinforcing ring 16 is sleeved on the outer wall of the second cylinder 12, and the reinforcing ring 16 is used for reinforcing the structural strength of the second cylinder 12 and avoiding thermal deformation.

The embodiment of the invention has the following remarkable effects: by providing the inner chamber 110 and the outer chamber 120 in the barrel 1, the first heating member 14 heats the welding wire in the inner chamber 110, and the second heating member 15 heats the welding wire in the outer chamber 120, and the first heating member 14 is heated at a temperature higher than that of the second heating member 15. So that the high temperature zone is located the middle part of stack shell 1, and the low temperature zone is located the week portion of stack shell 1, avoids second barrel 12 to receive high temperature to take place to warp the damage. During welding operation, welding rods can be baked in batches, baking waiting time is reduced, and welding and baking can be carried out simultaneously. Meanwhile, a welder clamps and uses the welding rod through the workpiece taking groove 13, and the switching frequency of the barrel cover 2 is reduced. The structure has the characteristics of convenient use and long service life, and is suitable for high-efficiency use in welding operation.
