Technical Field
[0001] The present application relates to the technical field of smoke collection and treatment, and in particular to a workshop welding smoke collection device. Background Art
[0002] Welding, also widely known as fusion or melting, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. This technology plays a vital role in modern industrial production and is widely used in various fields such as metal processing, construction, automobile manufacturing, aerospace and shipbuilding.
[0003] In current production practice, welding of metal structures is mostly carried out in workshops. However, a large amount of smoke and dust will be generated during the welding process. If these smoke and dust are not effectively sucked away in time, they will cause serious pollution to the working environment. The smoke and dust generated by welding operations contain a variety of harmful substances, including metal oxides, fluorides and other toxic compounds. These harmful substances are suspended in the air. If welders are exposed to an environment with excessive concentrations of these harmful substances for a long time, the air quality in the breathing zone will deteriorate rapidly. If effective protective measures are not taken, welders will inhale these excessive concentrations of harmful gases, which will cause great harm to their health.
[0004] In order to protect the health and safety of welding workers, most workshops are equipped with efficient dust collection devices to ensure that harmful smoke and dust can be removed in a timely and effective manner, reducing the harm of harmful substances to the body. At present, the dust collection device consists of a suction pipe and a suction hood. When in use, a large area of air is extracted in the smoke-generating area of the workpiece welding, and then the collected smoke and dust are processed.
[0005] With respect to the above-mentioned related technologies, the existing dust collecting devices are only applicable to occasions of fixed workstations and cannot be operated at different workstations. The scope of use is limited and thus needs to be improved. Summary of the invention

The servo motor 5 is installed on the mounting seat 2 and connected to the screw rod 3. The servo motor 5 is used to control the rotation of the screw rod 3.
[0040] The top suction hood 6 is installed on the slide 4 and is used to suck the smoke generated during the welding process. The storage box 7 is rectangular in shape. The storage box 7 is also installed on the mounting base 2 and is opened on one side. One end of the connecting pipe 8 is connected to the top suction hood 6, and the other end is connected to the storage box 7. The end of the connecting pipe 8 connected to the storage box 7 is movably set on the storage box 7, and the moving direction is parallel to the moving direction of the slide 4. The accordion cover 9 is telescopically set on the storage box 7 to cover the opening of the storage box 7. The telescopic direction of the accordion cover 9 is parallel to the moving direction of the slide 4. As shown in the figure, two accordion covers 9 are provided, and the two accordion covers 9 are on the same straight line. The connecting pipe 8 is located between the two accordion covers 9 and is connected to the two accordion covers 9 at the same time.
[0041] During welding, the welding table is used to place the metal frame to be welded, and the worker uses welding tools to perform welding operations on the welding table. The top suction hood 6 is arranged above the welding table, and uses negative pressure to collect the smoke generated during the welding process, so that the smoke enters the storage box 7, reducing the amount of smoke inhaled by personnel and reducing the harm of smoke to surrounding personnel, thereby realizing environmentally friendly welding of the metal frame.
[0042] When smoke and dust need to be collected at different workstations, the servo motor 5 can be operated, and the servo motor 5 controls the screw rod 3 to rotate, so that the slide 4 can move linearly along the screw rod 3, thereby driving the top suction hood 6 to move together, so as to move the top suction hood 6 to different workstations for collection, thereby improving the applicable scope of the smoke and dust collection device and meeting actual production needs. At the same time, when the slide 4 moves on the screw rod 3, due to the presence of the accordion cover 9, the slide 4 can drive the connecting pipe 8 to move together, and the accordion cover 9 will extend or contract accordingly to adapt to the movement of the connecting pipe 8; moreover, the two accordion covers 9 can always cover the opening of the storage box 7 to prevent the smoke and dust sucked into the storage box 7 by the top suction hood 6 from escaping.
[0043] Among them, the mounting seat 2 is also fixedly mounted with a guide rail 10, which is arranged along the length direction of the screw rod 3 and is close to the screw rod 3. As shown in the figure, two guide rails 10 are arranged in parallel, the screw rod 3 is located between the two guide rails 10, and the slide 4 is slidably connected to the two guide rails 10. When the screw rod 3 controls the slide 4 to move horizontally, the guide rail 10 can play the role of limiting and guiding, thereby improving the stability of the movement of the slide 4.
[0044] Specifically, the connecting pipe 8 includes a hard tube body 81, a first corrugated hose 82 and a second corrugated hose 83. One end of the first corrugated hose 82 is connected to the top suction hood 6, and the other end is connected to the hard tube body 81.

The hard tube body 81 is installed on the slide 4, and the two accordion covers 9 are connected to the hard tube body 81. The first corrugated hose 82 and the second corrugated hose 83 have certain flexibility, and the operator can adjust the direction of the top suction hood 6 within a certain range according to actual needs, so that the top suction hood 6 can better absorb smoke and dust. At the same time, the top suction hood 6 is connected at two points by the first corrugated hose 82 and the second corrugated hose 83, which can improve the stability of the position of the top suction hood 6.
[0045] One end of the storage box 7 is also connected to an exhaust pipe 13, and the end of the exhaust pipe 13 away from the storage box 7 is used to discharge smoke into the atmosphere. An atomization chamber, a purification chamber and a deodorization chamber are arranged between the exhaust pipe 13 and the storage box 7, and the atomization chamber, the purification chamber and the deodorization chamber are arranged in sequence along the exhaust direction. The atomization chamber is used to atomize and settle the smoke, the purification chamber is used to adsorb metal particles from the atomized smoke, and the deodorization chamber is used to deodorize and discharge the purified smoke. The smoke in the storage box 7 passes through the atomization chamber, the purification chamber and the deodorization chamber in sequence, and then is discharged into the air along the exhaust pipe 13, reducing the pollution of the smoke emission to the atmosphere.
[0046] Reference Figure 4 In this embodiment, the support assembly 1 includes a first cylinder 11 and a second cylinder 12, the first cylinder 11 and the second cylinder 12 are respectively located at the two ends of the mounting seat 2, the piston rod of the first cylinder 11 is hinged on one end of the mounting seat 2, and the piston rod of the second cylinder 12 is hinged on the other end of the mounting seat 2, and the first cylinder 11 and the second cylinder 12 are both retracted in the vertical direction. In some embodiments, the bottoms of the first cylinder 11 and the second cylinder 12 are fixedly connected with a support plate 20, and the support plate 20 is used to fit in contact with the ground to increase the stability of the mounting seat 2. Among them, the surface of the support plate 20 facing the ground is also provided with friction lines; the existence of the friction lines can increase the friction coefficient between the support plate 20 and the ground, thereby increasing the static friction.
[0047] The piston rods of the first cylinder 11 and the second cylinder 12 can jointly support the mounting seat 2, so that the mounting seat 2 can be placed stably. At the same time, since the first cylinder 11 and the second cylinder 12 are both hinged to the mounting seat 2, the staff can change the horizontality of the mounting seat 2 by changing the extension amount of the first cylinder 11 and the second cylinder 12. For example, if the extended length of the piston rod of the first cylinder 11 is greater than the extended length of the piston rod of the second cylinder 12, the mounting seat 2 will have a certain inclination, thereby correspondingly changing the direction of the top suction cover 6 and improving the production application range.
[0048] In addition, combined Figure 5 , a rotating seat 14, a lifting cylinder 15 and a return spring 16 are also installed below the mounting seat 2. The rotating seat 14 is installed on the ground and is located between the first cylinder 11 and the second cylinder 12. The lifting cylinder 15 is installed on the rotating seat 14, and the rotating seat 14 is used to control the rotation of the lifting cylinder 15, and the lifting cylinder 15 uses its own central axis as the rotating shaft. The piston rod of the lifting cylinder 15 is detachably connected to the bottom of the mounting seat 2, and a slot 17 is provided at the bottom of the mounting seat 2, and the piston rod of the lifting cylinder 15 is inserted into the slot 17. In some embodiments, a slide bar 18 is also fixedly connected to the end of the piston rod of the lifting cylinder 15, and a T-block 19 is slidably connected to the slide bar 18. The T-block 19 can be moved by pneumatic cylinder drive, and the cross-sectional area of the T-block 19 is larger than the cross-sectional area of the piston rod. The slot 17 is a T-slot, and the T-block 19 can be inserted into the T-slot.
[0049] When the position of the mounting base 2 needs to be adjusted, the lifting cylinder 15 can be operated to first push the slide bar 18 onto the mounting base 2; then the T-block 19 is controlled to slide horizontally on the slide bar 18 until the T-block 19 is completely inserted into the slot 17; finally, the lifting cylinder 15 is continued to be operated to lift the entire mounting base 2, so that the first cylinder 11 and the second cylinder 12 are slightly off the ground.
[0050] Then, the rotating seat 14 is operated, and the rotating seat 14 drives the lifting cylinder 15 to rotate with the vertical direction as the rotating axis, thereby changing the position of the mounting seat 2, so that the position of the top suction hood 6 will also be changed accordingly, so as to further increase the applicable scope of the smoke collection device. After the adjustment is completed, the T-block 19 is first controlled to disengage from the T-slot, and then the piston rod of the lifting cylinder 15 is controlled to move in a direction away from the mounting seat 2 and gradually retracted into the cylinder body, so as not to interfere with the adjustment of the horizontality of the mounting seat 2 by the first cylinder 11 and the second cylinder 12.
[0051] One end of the return spring 16 is connected to the bottom of the mounting seat 2, and the other end is connected to the cylinder body of the lifting cylinder 15. In this embodiment, the two ends of the return spring 16 are respectively hooked on the mounting seat 2 and the lifting cylinder 15. A plurality of return springs 16 are arranged at intervals, and as shown in the figure, two return springs 16 are symmetrically arranged.
[0052] The return spring 16 has good elastic deformation ability and can be stretched or compressed. When the lifting cylinder 15 lifts the mounting seat 2, the return spring 16 stretches to adapt; when the first cylinder 11 and the second cylinder 12 adjust the horizontality of the mounting seat 2, the return spring 16 can also deform accordingly to adapt to the changes. One end of the return spring 16 is always connected to the lifting cylinder 15. The presence of the return spring 16 improves the position stability of the mounting seat 2 when it is adjusted.
[0053] The implementation principle of a workshop welding fume collection device in the embodiment of the present application is as follows: when it is necessary to collect fume at different workstations, the servo motor 5 can be operated, and the servo motor 5 controls the screw rod 3 to rotate, so that the slide 4 can make a linear motion along the screw rod 3, thereby driving the top suction hood 6 to move together, so as to move the top suction hood 6 to different workstations for collection, thereby improving the applicable scope of the fume collection device and meeting the actual production needs. At the same time, when the slide 4 moves on the screw rod 3, due to the presence of the accordion cover 9, the slide 4 can drive the connecting pipe 8 to move together, and the accordion cover 9 will extend or contract accordingly to adapt to the movement of the connecting pipe 8; moreover, the two accordion covers 9 can always cover the opening of the storage box 7 to prevent the smoke sucked into the storage box 7 by the top suction hood 6 from escaping. Finally, the smoke in the storage box 7 passes through the atomization chamber, the purification chamber and the deodorization chamber in turn, and then is discharged into the air along the exhaust pipe 13, thereby reducing the pollution of the atmosphere by the smoke emission.
[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
