Description

Technical Field

[0001] This utility model relates to the field of manual welding equipment technology, and in particular to a fume recovery device for a manual welding station. Background Technology

[0002] Manual welding equipment refers to the complete set of devices and tools required for manual arc welding. Manual arc welding is an arc welding method that uses manual manipulation of welding rods. It relies on the welder's operating skills and experience and does not require complex automated devices.

[0003] Most existing manual welding station fume recovery devices on the market have fixed suction positions, making it difficult to flexibly adjust them according to actual welding operation needs. This limits their effectiveness in recovering the fumes generated during welding, resulting in insufficient practicality. Therefore, it is necessary to redesign a fume recovery device for manual welding stations to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fume recovery device for manual soldering stations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fume recovery device for a manual welding station includes a processing table. A screw is rotatably mounted on the bottom wall of the processing table via a movable frame. A motor connected to the screw is fixedly mounted on the outer wall of the movable frame. A movable block is rotatably mounted on the outer wall of the screw via a thread. A limit rod is fixedly mounted inside the movable frame, slidingly penetrating the movable block. A mixed-flow fan pump is fixedly mounted on the outer wall of the movable block via a support plate. An extension pipe is slidably and sealingly mounted on the outer wall of the inlet pipe of the mixed-flow fan pump. A dust suction hood is fixedly mounted on the outer wall of the extension pipe, and a fixing sleeve is fixedly mounted on the outer wall of the extension pipe. An installation frame is fixedly installed on the upper surface of the support plate. A connecting block is fixedly connected inside the installation frame via a lifting mechanism. The outer wall of the connecting block is connected to a fixed sleeve via a connecting mechanism. A purification box is fixedly installed on the outer wall of the processing table via a fixed plate. Multiple ventilation openings communicating with the interior are provided on the outer wall of the purification box. A connecting pipe communicating with the interior is fixedly installed on the upper surface of the purification box. A telescopic flexible hose is fixedly installed on the outer wall of the outlet pipe of the mixed flow fan pump. The end of the telescopic flexible hose is fixedly connected to the outer wall of the connecting pipe. Multiple activated carbon plates are slidably and sealed on the upper surface of the purification box via slots.

[0007] Preferably, the lifting mechanism includes an electric push rod fixedly installed inside the mounting frame, the telescopic end of the electric push rod being fixedly connected to the upper end face of the connecting block, and the upper end face of the support plate having a lifting opening that cooperates with the telescopic end of the electric push rod.

[0008] Preferably, the connecting mechanism includes a connecting rod that is fixedly installed on the outer wall of the connecting block, and the end of the connecting rod is fixedly connected to the outer wall of the fixed sleeve.

[0009] Preferably, a support rod is fixedly installed on the outer wall of the purification box, and a first connecting block is fixedly installed at the end of the support rod.

[0010] Preferably, a connecting plate is rotatably mounted on the end of the first connecting block, and a pressing bolt is rotatably mounted on the upper surface of the connecting plate through a thread.

[0011] Preferably, a second connecting block is fixedly installed at the end of the extrusion bolt, and an extrusion plate is rotatably installed on the bottom wall of the second connecting block.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as screw, moving block and support plate, the motor drives the screw to rotate. Under the dual action of screw transmission and limit rod, the moving block can move smoothly along the screw axis, thereby driving the support plate, mixed flow fan pump, extension pipe and dust hood to adjust their positions laterally. This design allows the dust hood to easily cover different welding stations and greatly improves the efficiency of dust collection.

[0014] 2. By setting up components such as extension rods, electric push rods, and connecting blocks, the electric push rods extend and retract, driving the connecting blocks to move up and down. The connecting blocks are connected to the fixed sleeves through the connecting rods, which in turn pulls the extension tube and the dust collection hood to rise and fall. Whether it is fine welding at a low position or welding of large workpieces at a higher position, the dust collection hood can be quickly adjusted to a suitable height, always maintaining the ideal distance from the welding point, ensuring efficient absorption of welding fumes.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A fume recovery device for a manual welding station includes a processing table 1. A screw 3 is rotatably mounted on the bottom wall of the processing table 1 via a movable frame 2. A motor 4 connected to the screw 3 is fixedly mounted on the outer wall of the movable frame 2. A movable block 6 is rotatably mounted on the outer wall of the screw 3 via a thread. A limit rod 5 is fixedly mounted inside the movable frame 2, and the limit rod 5 slides through the movable block 6. A mixed-flow fan pump 8 is fixedly mounted on the outer wall of the movable block 6 via a support plate 7. An extension pipe 9 is slidably and sealingly mounted on the outer wall of the inlet pipe of the mixed-flow fan pump 8. A dust suction hood 10 is fixedly mounted on the outer wall of the extension pipe 9. A fixing sleeve 11 is fixedly mounted on the outer wall of the extension pipe 9. The upper end of the support plate 7... A mounting frame 12 is fixedly installed on the surface. A connecting block 14 is fixedly connected inside the mounting frame 12 via a lifting mechanism. The outer wall of the connecting block 14 is connected to the fixing sleeve 11 via a connecting mechanism. A purification box 17 is fixedly installed on the outer wall of the processing table 1 via a fixing plate 16. Multiple ventilation openings communicating with the interior are provided on the outer wall of the purification box 17. A connecting pipe 18 communicating with the interior is fixedly installed on the upper surface of the purification box 17. A telescopic flexible hose 19 is fixedly installed on the outer wall of the outlet pipe of the mixed flow fan pump 8. The end of the telescopic flexible hose 19 is fixedly connected to the outer wall of the connecting pipe 18. Multiple activated carbon plates 20 are slidably installed on the upper surface of the purification box 17 via slot sealing.

[0024] The lifting mechanism includes an electric push rod 13 fixedly installed inside the mounting frame 12. The telescopic end of the electric push rod 13 is fixedly connected to the upper end face of the connecting block 14. The upper end face of the support plate 7 has a lifting opening that cooperates with the telescopic end of the electric push rod 13.

[0025] Furthermore, the electric actuator 13 features high precision and good stability. Its extension stroke and speed can be precisely controlled according to the height requirements of the actual welding operation. The design of the lifting opening provides space for the extension and retraction of the electric actuator 13, and also plays a certain guiding role, ensuring that the connecting block 14 can move up and down smoothly, thereby driving the dust collection hood 10 to achieve vertical height adjustment.

[0026] The connecting mechanism includes a connecting rod 15 that is fixedly installed on the outer wall of the connecting block 14, and the end of the connecting rod 15 is fixedly connected to the outer wall of the fixing sleeve 11.

[0027] Furthermore, the connecting rod 15 needs to be made of high-strength metal material to ensure reliable force transmission between the connecting block 14 and the fixing sleeve 11. The connection can be made by welding to ensure a strong connection. Through this connection mechanism, the extension and retraction of the electric actuator 13 can be accurately transmitted to the extension tube 9 and the dust hood 10, achieving effective adjustment of the height of the dust hood 10.

[0028] A support rod 21 is fixedly installed on the outer wall of the purification box 17, and a first connecting block 22 is fixedly installed at the end of the support rod 21.

[0029] Furthermore, the support rod 21 serves to support and fix the structure, and must have sufficient strength and rigidity to ensure the stability of the entire purification chamber 17.

[0030] A connecting plate 23 is rotatably mounted on the end of the first connecting block 22, and a pressing bolt 24 is rotatably mounted on the upper surface of the connecting plate 23 through a thread.

[0031] Furthermore, the rotatable connection between the connecting plate 23 and the first connecting block 22 should ensure flexible rotation and a certain degree of damping to prevent erratic shaking during use.

[0032] A second connecting block 25 is fixedly installed at the end of the extrusion bolt 24, and an extrusion plate 26 is rotatably installed on the bottom wall of the second connecting block 25.

[0033] Furthermore, the second connecting block 25 and the extrusion bolt 24 must be firmly fixed to ensure that the extrusion plate 26 can be reliably moved when the extrusion bolt 24 is rotated. The rotating installation design of the extrusion plate 26 allows it to better adapt to the surface shape of the activated carbon plate 20 when extruding it, ensuring the uniformity of extrusion, thereby improving the stability of the activated carbon plate 20 installation and the purification effect.

[0034] When this utility model is in use, the mixed-flow fan pump 8 can suck up the welding fumes through the extension pipe 9 and the dust suction hood 10, and discharge them into the purification box 17 through the telescopic hose 19. After the fumes enter the purification box 17, they first come into full contact with multiple activated carbon plates 20 inside the box. The activated carbon plates 20 use their rich pore structure and strong adsorption force to firmly adsorb the metal particles, harmful gases and other pollutants in the fumes, achieving preliminary purification. As the purification process continues, the purified air forms an airflow in the purification box 17 and is discharged in an orderly manner through multiple ventilation openings on the side wall of the box. These ventilation openings are reasonably distributed, which not only ensures the smooth discharge of purified air, but also maintains the stability of the airflow inside the purification box 17, ensuring that the fumes can fully interact with the activated carbon plates 20 inside the box.

[0035] During the operation of the device, the motor 4 drives the screw 3 to rotate, which in turn moves the moving block 6 and the connected mixed-flow fan pump 8, dust hood 10 and other components in the horizontal direction, allowing for flexible adjustment of the dust collection position. The electric push rod 13 extends and retracts to push the connecting block 14, connecting rod 15 and fixing sleeve 11, enabling the dust hood 10 to be adjusted vertically to accommodate welding operations at different heights. When the activated carbon plate 20 becomes saturated with adsorption and the purification effect decreases, the pressing bolt 24 on the connecting plate 23 is rotated in the opposite direction, causing the pressing bolt 24 to move the second connecting block 25 and the pressing plate 26 upward, thus releasing the pressing and fixing of the activated carbon plate 20.

[0036] Subsequently, using the first connecting block 22 as the pivot point, the connecting plate 23 is manually rotated. Since the first connecting block 22 and the connecting plate 23 are rotatably connected, the connecting plate 23 can rotate flexibly around its connection point. As the connecting plate 23 rotates, the compression bolt 24, the second connecting block 25, and the compression plate 26 connected to the connecting plate 23 are driven together, causing the compression plate 26 to move out from the upper surface of the purification box 17 and no longer block the slot on the upper surface of the purification box 17. At this time, the old activated carbon plate 20 that has been adsorbed to saturation can be smoothly pulled out from the slot, and the new activated carbon plate 20 is inserted into the slot. After insertion, the above steps are reversed. First, the connecting plate 23 is rotated so that the compression plate 26 is reset to the top of the purification box 17. Then, the compression bolt 24 is rotated in the forward direction to drive the compression plate 26 to move downward, pressing and fixing the newly inserted activated carbon plate 20 to ensure that the activated carbon plate 20 is stably installed and tightly arranged, thereby ensuring the purification effect of the purification box 17 and enabling the entire dust collection device to operate continuously and efficiently.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
