Description

Technical Field

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

[0002] Flux-cored welding wire, also known as powder-cored welding wire or tubular welding wire, is divided into two main categories: gas-shielded and non-gas-shielded. The surface of flux-cored welding wire is the same as that of solid welding wire, and it is made of materials with good plasticity, such as low-carbon steel or low-alloy steel. The manufacturing process involves first rolling a steel strip into a U-shaped cross-section, then filling the U-shaped steel strip with a pre-mixed welding powder, pressing it tightly with a rolling mill, and finally drawing it into flux-cored welding wires of different specifications.

[0003] The flux core of flux-cored welding wire typically contains various metal powders (such as high-chromium cast iron, carbides, etc.), with significant differences in particle size, density, and shape. If the mixing is uneven, it will lead to uneven distribution of components during welding, affecting the hardness and wear resistance of the weld overlay. Therefore, in order to ensure product quality, the flux core of the welding wire usually needs to be mixed before production.

[0004] After prolonged use, existing equipment will have some material residue inside, so the device needs to be disassembled for cleaning. However, most existing equipment uses traditional bolt or flange connections, which requires the use of various tools for tightening during installation and disassembly, which is very inconvenient. Therefore, we have proposed a wear-resistant welding wire flux-cored mixing device. Utility Model Content

[0005] The purpose of this utility model is to provide a flux-cored mixing device for wear-resistant welding wire. Through the installation structure and mixing mechanism, it solves the problem that after long-term use, some material will remain inside the existing equipment, so the device needs to be disassembled for cleaning. Most existing equipment adopts traditional bolt or flange connection methods, which requires the use of multiple tools for tightening during installation and disassembly, which is very inconvenient.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a flux-cored mixing device for wear-resistant welding wire, including a V-shaped mixing barrel. A V-shaped mixing barrel is fixedly connected to the outer wall of the V-shaped mixing barrel. A mixing box is slidably connected to the bottom outer wall of the V-shaped mixing barrel. A conveyor is fixedly connected to the outer wall of the mixing box. A sieve plate is slidably connected to the inner wall of the mixing box. An installation mechanism is provided on the outer wall of the V-shaped mixing barrel.

[0008] The installation mechanism includes several fixing blocks. The outer walls of the fixing blocks are fixedly connected to the outer wall of the mixing tank. The bottom outer walls of the fixing blocks are rotatably connected to threaded rods. The outer walls are threadedly connected to connecting rods. The inner walls of the connecting rods are fixedly connected to several limiting shafts. The outer walls of the limiting shafts are rotatably connected to fixing blocks II. The outer walls of fixing blocks II are slidably connected to the outer wall of the V-shaped mixing tank. The inner walls of fixing blocks II have arc-shaped grooves. The inner walls of the arc-shaped grooves are slidably connected to limiting rods.

[0009] Furthermore, the outer walls of several of the limiting rods are fixedly connected to the inner wall of the mixing tank, and several bolts are threadedly connected to the outer wall of the V-shaped mixing bucket near the mixing tank. The outer wall of the mixing tank is provided with a mixing mechanism.

[0010] Furthermore, the mixing mechanism includes a connecting frame, the outer wall of which is fixedly connected to the bottom outer wall of the mixing tank, a motor is fixedly connected to the top outer wall of the connecting frame, and a drive shaft is fixedly connected to the bottom output end of the motor via a coupling.

[0011] Furthermore, a gear disk is fixedly connected to the outer wall of the drive shaft, and a fixing plate is fixedly connected to the bottom outer wall of the mixing tank near the gear disk, with the outer wall of the fixing plate rotatably connected to the outer wall of the gear disk.

[0012] Furthermore, the inner wall of the fixed plate is rotatably connected to several rotating shafts, and the outer wall of the rotating shafts is fixedly connected to gears, the outer wall of the gears meshing with the outer wall of the gear disk.

[0013] Furthermore, a second gear is fixedly connected to the outer wall of the end of the rotating shaft away from the gear, and several rotating shafts are rotatably connected to the inner wall of the fixed plate.

[0014] Furthermore, each of the outer walls of the rotating shafts is fixedly connected to a connecting rod, and the outer wall of the connecting rod is fixedly connected to a fixing rod.

[0015] Furthermore, a stirring rod is fixedly connected to the outer wall of the fixed rod, and a gear three is fixedly connected to the outer wall of the end of the rotating shaft two away from the connecting rod two, and the outer wall of the gear three meshes with the outer wall of the gear two.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model incorporates a limiting shaft on the connecting rod. When the equipment is in use, rotating the threaded rod causes the connecting rod to move upward, which in turn moves the limiting shaft upward. This movement of the limiting shaft causes the second fixing block to move upward and slide on the limiting rod. Due to the irregular shape of the arc-shaped groove, when the limiting rod moves upward a certain distance, the second fixing block will slide along the arc-shaped groove, causing the top of the second fixing block to retract inward by one end. This allows for the installation and fixation of the V-shaped mixing tank and the mixing box. The installation method is simple and convenient, facilitating quick disassembly by the user and subsequent thorough cleaning and maintenance of the mixing chamber, preventing cross-contamination when using different core formulations.

[0018] 2. This utility model incorporates gears on a rotating shaft. During operation, the motor's rotation drives the transmission shaft, causing the gear disc to rotate. This rotation drives multiple gears, which in turn drive the rotating shaft. The rotating shaft then drives gear two, which in turn drives gear three. Gear three's rotation causes rotating shaft two to rotate within the fixed plate. Simultaneously, rotating shaft two's rotation drives connecting rod two, which in turn drives the fixed rod. The fixed rod's rotation then drives the stirring rod, achieving uniform mixing of the flux core and ensuring the overall structure and dimensional accuracy of the subsequently produced welding wire.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 As shown, this utility model is a flux-cored mixing device for wear-resistant welding wire, including a V-shaped mixing tank 1. The outer wall of the V-shaped mixing tank 1 is fixedly connected to a mixing chamber 101. The bottom outer wall of the V-shaped mixing tank 1 is slidably connected to a mixing box 101. The outer wall of the mixing box 101 is fixedly connected to a conveyor 102. The inner wall of the mixing box 101 is slidably connected to a sieve plate 103. An installation mechanism 2 is provided on the outer wall of the V-shaped mixing tank 1. The feeding rate between the V-shaped mixing tank 1 and the mixing box 101 can be controlled by the sieve plate 103.

[0031] The mounting mechanism 2 includes several fixing blocks 201. The outer walls of the fixing blocks 201 are fixedly connected to the outer wall of the mixing tank 101. The bottom outer walls of the fixing blocks 201 are rotatably connected to threaded rods 202. The outer walls of the fixing blocks 201 are threadedly connected to connecting rods 203. The inner walls of connecting rods 203 are fixedly connected to several limiting shafts 204. The fixing blocks 201 can limit the position of the threaded rods 202 to prevent the fixing blocks 201 from falling off. The outer walls of the limiting shafts 204 are rotatably connected to fixing blocks 205. The outer walls of fixing blocks 205 are slidably connected to the outer wall of the V-shaped mixing tank 1. The inner walls of fixing blocks 205 are provided with arc-shaped grooves 206. The inner walls of the arc-shaped grooves 206 are slidably connected to limiting rods 207. The limiting rods 207 can limit the movement trajectory of fixing blocks 205. Fixing blocks 205 can only slide on the limiting rods 207.

[0032] The outer walls of several limiting rods 207 are fixedly connected to the inner wall of the mixing tank 101. Several bolts 208 are threadedly connected to the outer wall of the V-shaped mixing bucket 1 near the mixing tank 101. A mixing mechanism 3 is provided on the outer wall of the mixing tank 101. The mixing mechanism 3 includes a connecting frame 301, which limits the position of the motor 302 to prevent the motor 302 from vibrating violently during rotation and affecting its subsequent normal use. The outer wall of the connecting frame 301 is fixedly connected to the bottom outer wall of the mixing tank 101, and the top outer wall of the connecting frame 301 is fixedly connected to the motor 302. 2. The bottom output end of the motor 302 is fixedly connected to the transmission shaft 303 via a coupling. When the motor 302 is started, the rotation of the motor 302 will drive the transmission shaft 303 to rotate, which in turn will drive the gear disk 304 to rotate. The outer wall of the transmission shaft 303 is fixedly connected to the gear disk 304. The bottom outer wall of the mixing tank 101 near the gear disk 304 is fixedly connected to the fixing plate 305. The outer wall of the fixing plate 305 is rotatably connected to the outer wall of the gear disk 304. The fixing plate 305 can fix the position of the rotating shaft 306 to prevent the rotating shaft 306 from falling off when rotating.

[0033] The inner wall of the fixed plate 305 is rotatably connected to several rotating shafts 306. Gears 307 are fixedly connected to the outer wall of each rotating shaft 306, and the outer wall of each gear 307 meshes with the outer wall of a gear disk 304. A second gear 308 is fixedly connected to the outer wall of the rotating shaft 306 away from the gear 307. Because the gear 307 meshes with the gear disk 304, rotating the gear disk 304 will drive the gear 307 to rotate. The inner wall of the fixed plate 305 is also rotatably connected to several second rotating shafts 309, and connecting rods 310 are fixedly connected to the outer walls of each second rotating shaft 309. A fixing rod 311 is fixedly connected to the outer wall of the second connecting rod 310. The position of the fixing rod 311 can be fixed by the second connecting rod 310. When the second connecting rod 310 rotates, it will drive the fixing rod 311 to rotate. A stirring rod 312 is fixedly connected to the outer wall of the rotating shaft 309 away from the second connecting rod 310. A gear 313 is fixedly connected to the outer wall of the rotating shaft 309 away from the second connecting rod 310. The outer wall of the gear 313 meshes with the outer wall of the gear 2 308. When the stirring rod 312 rotates, it will drive the material in the mixing box 101 to stir, so that it is fully mixed.

[0034] One specific application of this embodiment is:

[0035] When the equipment is needed, the required drug core material is placed in different containers of the V-shaped mixing tank 1. Then, the sliding sieve plate 103 controls the speed at which the material enters the mixing tank 101, and the motor 302 is started. The rotation of the motor 302 drives the transmission shaft 303 to rotate, causing the gear disc 304 to rotate. The rotation of the gear disc 304 drives multiple gears 307, causing the rotating shaft 306 to rotate. The rotation of the rotating shaft 306 drives gear two 308 to rotate, which in turn drives gear three 313 to rotate. The rotation of gear three 313 causes rotating shaft two 309 to rotate within the fixed plate 305. Simultaneously, the rotation of rotating shaft two 309 drives connecting rod two 310 to rotate, causing the fixed rod 311 to rotate. The rotation of the fixed rod 311 drives the stirring rod 312 to rotate, thus mixing the material in the mixing tank 101. After mixing is complete... The materials can be promptly transported to the subsequent devices by starting the conveyor 102. When it is necessary to disassemble the V-shaped mixing barrel 1 from the mixing box 101 for cleaning, rotate the threaded rod 202. The rotation of the threaded rod 202 will drive the connecting rod 203 to move upward, and the limiting shaft 204 will move upward. The movement of the limiting shaft 204 will drive the fixed block 205 to move upward as a whole and slide on the limiting rod 207. Since the arc groove 206 has an irregular shape, when the limiting rod 207 moves upward to a certain distance, the fixed block 205 will slide along the arc groove 206, causing the top of the fixed block 205 to retract inward by one end. At this time, the fixed block 205 will no longer be clamped on the surface of the V-shaped mixing barrel 1. Then, remove the multiple bolts 208, and the V-shaped mixing barrel 1 and the mixing box 101 can be separated.
