Description

Technical Field

[0001] This utility model belongs to the field of welding technology, and in particular relates to a structure for the flux-cored feeding port of wear-resistant welding wire. Background Technology

[0002] The flux-cored wire feed port structure is a common equipment component in the welding industry, playing a crucial role, especially in the production of wear-resistant welding wire. Flux-cored welding wire is mainly used for welding applications under special conditions such as wear resistance, high temperature resistance, and corrosion resistance, and is commonly found in industries such as metallurgy, mining, machinery, and engineering.

[0003] Welding wires of different diameters and with different material requirements require flux cores of different compositions. Therefore, it is necessary to accurately dispense the flux core according to the specifications of the welding wire and the target application to ensure that the weld can meet the expected performance requirements. Therefore, we propose a flux core feeding port structure for wear-resistant welding wires. Utility Model Content

[0004] The purpose of this utility model is to provide a flux core feeding port structure for wear-resistant welding wire. During the movement of the limiting block, the limiting plate will rotate, thereby causing the rotating shaft to rotate. When the rotating shaft rotates, it will drive the quantitative baffle to rotate, thus solving the problem that welding wires with different diameters and material requirements need flux cores with different compositions.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a structure for a wear-resistant welding wire flux core feeding port, including a fixing plate, a support frame fixedly connected to the top of the fixing plate, a material conveying pipe fixedly connected to the inner wall of the support frame, a metering mechanism on the support frame, and a flow rate matching mechanism on the fixing plate.

[0007] The metering mechanism includes a feed frame fixedly connected to the top of the conveying pipe. A rotating shaft is rotatably connected to the inner wall of the feed frame. A metering baffle is fixedly connected to the outer wall of the rotating shaft. A limiting plate is fixedly connected to the outer wall of the rotating shaft. A sliding groove is provided inside the feed frame. A limiting block is slidably connected to the inner wall of the sliding groove. A reverse threaded rod is rotatably connected to the inner wall of the limiting block. A worm gear is fixedly connected to the outer wall of the reverse threaded rod. A worm is threadedly connected to the outer wall of the worm gear. A through groove is provided inside the feed frame.

[0008] Furthermore, there are two rotating shafts in total, the outer wall of the limiting block is slidably connected to the inner wall of the limiting plate, and the outer wall of the reverse threaded rod is rotatably connected to the outer wall of the feed frame.

[0009] Furthermore, the outer wall of the worm gear is rotatably connected to the inner wall of the feed frame, and the inner wall of the through groove is slidably connected to the outer wall of the limiting plate.

[0010] Furthermore, the flow rate matching mechanism includes two fixed columns fixedly connected to the top of the fixed plate. The bottom of the conveying pipe is fixedly connected to the second conveying pipe, and a cross baffle is rotatably connected to the inner wall of the second conveying pipe.

[0011] Furthermore, a second rotating shaft is fixedly connected to the outer wall of the cross baffle, the outer wall of the second rotating shaft is rotatably connected to the inner wall of the second conveying pipe, a motor is fixedly connected to the outer wall of the second fixed column, and the output shaft of the motor is fixedly connected to a third rotating shaft via a coupling.

[0012] Furthermore, the outer wall of the rotating shaft three is rotatably connected to the inner wall of the fixed column two, a pulley one is fixedly connected to the outer wall of the rotating shaft three, a belt is drivenly connected to the outer wall of the pulley one, and a pulley two is drivenly connected to the end of the belt away from the pulley one, and the inner wall of the pulley two is fixedly connected to the outer wall of the rotating shaft two.

The outer wall of the fixed column is fixedly connected to the outer wall of the fixed plate. The two fixed columns are fixedly connected to a groove on the side that is close to each other.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a limiting plate. Manually rotating the worm gear drives the worm wheel to rotate. Simultaneously, the worm wheel rotates, causing the reverse threaded rod to rotate. This rotation, in turn, causes the limiting blocks to slide within the groove, moving them closer or further apart. During this movement, the limiting blocks rotate, causing the limiting plate to rotate, which in turn rotates the rotating shaft. This rotation, in turn, causes the quantitative baffle to rotate, allowing for adjustment of the opening size. This mechanism allows for manual adjustment of the opening size, enabling adjustments to the flux-cored charge amount based on different welding wire specifications.

[0017] 2. This utility model incorporates a cross baffle. The drug core is fed into the feed frame and conveying pipe, falling into the second conveying pipe. The motor is then started, driving the third rotating shaft to rotate, which in turn drives the first pulley to rotate, thus moving the belt. Simultaneously, the belt rotates the second pulley, which in turn drives the second rotating shaft. The rotation of the second rotating shaft, in turn, drives the cross baffle to rotate. This mechanism can adjust the flow rate of the drug core, ensuring that the drug core flow rate matches the speed of the steel belt.

[0030] The metering mechanism 2 includes an infeed frame 201 fixedly connected to the top of the conveying pipe 103. A rotating shaft 202 is rotatably connected to the inner wall of the infeed frame 201. A metering baffle 203 is fixedly connected to the outer wall of the rotating shaft 202. A limiting plate 204 is fixedly connected to the outer wall of the rotating shaft 202.

When the worm gear 209 rotates, it drives the worm wheel 208 to rotate, which in turn drives the reverse threaded rod 206 to rotate, causing the two limit blocks 205 to slide in the slide groove 207. The feed frame 201 has a through groove 210 inside. There are two rotating shafts 202. The outer wall of the limit block 205 is slidably connected to the inner wall of the limit plate 204, and the outer wall of the reverse threaded rod 206 is rotatably connected to the outer wall of the feed frame 201.

The outer wall of the worm gear 209 is rotatably connected to the inner wall of the feed frame 201, and the inner wall of the through groove 210 is slidably connected to the outer wall of the limit plate 204.

[0031] The flow rate matching mechanism 3 includes two fixed columns 315 fixedly connected to the top of the fixed plate 101.

A cross baffle 302 is rotatably connected to the inner wall of the second conveying pipe 301, allowing continuous feeding of the drug core. A second rotating shaft 303 is fixedly connected to the outer wall of the cross baffle 302, and the outer wall of the second rotating shaft 303 is rotatably connected to the inner wall of the second conveying pipe 301. A motor 304 is fixedly connected to the outer wall of the fixed column 315. The output shaft of the motor 304 is fixedly connected to a third rotating shaft 305 via a coupling. Through the second conveying pipe 301, the drug core passes through the feed frame 201 and... After the material conveying pipe 103, it enters the material conveying pipe 2 301, where the core is conveyed by the cross baffle 302. The outer wall of the rotating shaft 305 is rotatably connected to the inner wall of the fixed column 2 315. The outer wall of the rotating shaft 305 is fixedly connected to the pulley 1 306. The outer wall of the pulley 1 306 is driven by the belt 307. The end of the belt 307 away from the pulley 1 306 is driven by the pulley 2 308. By setting the rotating shaft 305, when the rotating shaft 305 rotates, it will drive the pulley 1 306 to rotate, thereby driving the belt 307 to move, and then driving the pulley 2 308 to rotate. The inner wall of the pulley 2 308 is fixedly connected to the outer wall of the rotating shaft 2 303.

[0032] A pulley 309 is fixedly connected to the outer wall of the rotating shaft 305. A conveyor belt 310 is driven to the outer wall of the pulley 309. A pulley 4 311 is driven to the end of the conveyor belt 310 away from the pulley 309. A rotating shaft 4 312 is fixedly connected to the inner wall of the pulley 4 311. By setting the pulley 309, when the pulley 309 rotates, it will drive the conveyor belt 310 to move, conveying the drug core on the surface of the conveyor belt 310. A fixed post 313 is rotatably connected to the outer wall of the rotating shaft 4 312. There are two fixed posts 313. The outer wall of the fixed post 313 is fixedly connected to the outer wall of the fixed plate 101.

By setting the groove 314, the drug core conveyed by the conveyor belt 310 will fall into the groove 314 for subsequent operations.

[0033] One specific application of this embodiment is:

[0034] First, manually rotate the worm gear 209 to drive the worm wheel 208 to rotate. Simultaneously, the worm wheel 208 rotates, driving the reverse threaded rod 206 to rotate. This rotation of the reverse threaded rod 206 causes the limiting blocks 205 to slide within the groove 207, allowing them to move closer or further apart. During this movement, the limiting blocks 205 drive the limiting plate 204 to rotate, causing the rotating shaft 202 to rotate. This rotation of the rotating shaft 202 drives the metering baffle 203 to rotate. The size of the opening can be adjusted by manually rotating the metering baffle 203, allowing for manual adjustment of the flux core feed rate according to different welding wire specifications. The flux core is then fed through the feed frame 201 and the conveying pipe 103, falling into the conveying pipe 301. Then, the motor 3 is started. 04. The rotating shaft 305 rotates, which in turn rotates the pulley 306, causing the belt 307 to move. When the belt 307 moves, it rotates the pulley 308, which in turn rotates the rotating shaft 303. When the rotating shaft 303 rotates, it rotates the cross baffle 302, which puts the drug core above the cross baffle 302 onto the conveyor belt 310. Then, as the rotating shaft 305 rotates, it rotates the pulley 309, which in turn rotates the conveyor belt 310, causing the pulley 311 to rotate. When the conveyor belt 310 starts to move, it moves the drug core that is above the conveyor belt 310, causing the drug core to fall into the groove 314. This mechanism can adjust the flow rate of the drug core to ensure that the drug core flow rate matches the speed of the steel belt.
