[0023] 2.

The support frame changes, pulling the rotating column to change. The rotating column changes, pulling the control plate to change and move to the upper end of the first channel. Then, the polluted air will pull the control plate to rotate while flowing into the first channel. The control plate rotates, touches and pushes the changing plate to change. The changing plate changes and presses the third linear push rod. Then, the inflow of polluted air is restricted by restricting the rotation speed of the control plate to control the polluted air. This prevents the polluted air from being sprayed into the treatment box when the amount of polluted air is too large, causing the polluted air and the absorbent to not have enough contact, thereby weakening the treatment function of the polluted air. The movable disc moves downward and touches the pressure column, which moves downward. The pressure column moves downward and pulls the pressure disc to move downward. The pressure disc moves downward and pulls the connecting strip to move downward. The connecting strip moves downward and pulls the blocking piece to move downward. The blocking piece moves downward to open the discharge slot of the discharge channel, and the air absorbed in the treatment box contacts the ventilation sheet and the adsorbed carbon particles through the second channel and is treated. After the treatment, the air is discharged through the discharge channel, which can prevent external debris from falling into the treatment barrel through the discharge channel when the device is not running, thereby weakening the treatment function of the polluted air. The variable traction barrier rod moves downward, and the barrier rod moves downward to the active stroke of the flip plate. During the rotation of the linkage rod, the rotating plate is pulled to rotate, and the rotation of the rotating plate pulls the bearing bar to rotate. The rotation of the bearing bar pulls the flip plate to rotate around the linkage rod. During the rotation of the flip plate, it touches the barrier rod and rotates automatically. When the flip plate continues to rotate and no longer touches the barrier rod, the flip plate returns to its original position with the cooperation of the torsion spring and throws out the adsorbed carbon particles on the flip plate, so as to achieve the purpose of flipping the adsorbed carbon particles, allowing the adsorbed carbon particles to have sufficient contact with the polluted air, and further enhance the polluted air treatment function.

Then the arched bar 76 rotates to scrape the debris close to the inner wall of the clean air tank 71 into the storage box 79, so as to collect the debris and clean it together later, and prevent the accumulation of a large amount of debris on the separation sheet 74 to reduce the function of polluted air treatment.

The outer cover 720 is made of high temperature resistant rubber material. The outer cover 720 is connected to the C-shaped collecting channel 721, and the collecting channel 721 is connected to the connecting channel 2 725. During welding, the high pressure fan 724 draws the polluted gas caused by welding into the connecting channel 1 722 through the outer cover 720 and the connecting channel 2 725, ensuring that the polluted gas generated by welding is quickly drawn into the clean gas tank 71 for purification.

[0057] Reference Fig.14 The first linear push rod 715 includes an outer tube, a T-shaped rod and a third spiral beryllium copper wire. The T-shaped rod is movably installed on the inner side of the outer tube. The outer surface of the T-shaped rod is clamped with the third spiral beryllium copper wire. One end of the T-shaped rod passes through the outer tube. The first linear push rod 715, the second linear push rod 717 and the third linear push rod 71813 have the same structure.

[0058] The specific implementation method is as follows: during welding, the bracket is placed in the clamping opening 46 on the lower clamping plate 42, the hydraulic rod 3 43 is contracted, and the upper clamping plate 44 is pulled to move downward, and then the bracket is clamped and fixed by the upper clamping plate 44 and the lower clamping plate 42, and the foot pedal is placed between the clamping plate 1 32 and the clamping plate 2 34 according to the welding needs, the hydraulic rod 2 33 is contracted, and the clamping plate 2 34 is pulled to move until the clamping plate 1 32 and the clamping plate 2 34 clamp the foot pedal, and after the foot pedal and the bracket are stably clamped, the hydraulic rod 1 21 is extended to lift the foot pedal To a horizontal position where the bracket can be welded, the motor 26 pulls the lead screw 24 to rotate, and the lead screw 24 pulls the slider 25 to move, and then the pedal clamped on the pedal clamping module 3 is moved to touch the bracket welding position, and the mechanical arm 51 moves, and the welding head 52 is adjusted to the welding position to perform welding on the bracket and the pedal. The welding module 5 will pollute the air at the welding position during welding, and will also produce some solid matter, smoke, etc. The clean air module 7 extracts the polluted air and the generated solid matter, and then treats the polluted air;

[0059] When the polluted air is treated, the hoop 75 rotates through the thread mouth to pull the movable disc 7184 to move downward, and the movable disc 7184 moves downward to pull the connecting rod 7185 to move, and the connecting rod 7185 moves to pull the movable frame 7186 to move. The movable frame 7186 moves to connect the air inlet on its wall with the first channel 7182, and then allows the polluted air after the first peeling to flow into the treatment box 7183 through the separation sheet 74 and the first channel 7182 on the wall of the barrier disc 7181, and with the cooperation of the absorbent, the impurities that affect health are removed, which can prevent the absorbent in the treatment box 7183 from floating to the upper end with the air when the polluted air is not treated, causing erosion of the device, thereby increasing the investment in subsequent maintenance and the change of the movable frame 7186. The dynamic traction support frame 7189 moves, and the movement of the support frame 7189 pulls the rotating column 71810 to move. The movement of the rotating column 71810 pulls the control plate 71811 to move and move to the upper end of the first channel 7182. Then, the polluted air will pull the control plate 71811 to rotate while flowing into the first channel 7182. The control plate 71811 rotates, touches and pushes the moving plate 71812 to move. The moving plate 71812 moves and presses the third linear push rod 71813. Then, the control plate 71811 is restricted by the rotation speed to restrict the inflow of polluted air to control the polluted air, so as to prevent the polluted air from being sprayed into the treatment box 7183 when the amount of polluted air is too large, resulting in insufficient contact between the polluted air and the absorbent, thereby weakening the treatment function of the polluted air.

[0060] The movable disc 7184 moves downward, touches and compresses the compression column 7194 to move downward, the compression column 7194 moves downward, pulling the compression disc 7195 to move downward, the compression disc 7195 moves downward, pulling the connecting strip 7196 to move downward, the connecting strip 7196 moves downward, pulling the blocking piece 7198 to move downward, the blocking piece 7198 moves downward to open the discharge slot of the exhaust channel 7197, and the air absorbed in the treatment box 7183 passes through the second channel 7193 and touches the ventilation sheet 7192 and the adsorbed carbon particles and is treated, and then the air after the treatment is completed is discharged through the exhaust channel 7197, which can prevent external debris from falling into the treatment barrel 7191 through the exhaust channel 7197 when the device is not in operation, thereby weakening the treatment function of the polluted air, and the compression disc 7195 moves downward. The blocking rod 71911 is pulled to move downward, and the blocking rod 71911 moves downward to the active stroke of the flip plate 71913. During the rotation of the linkage rod 73, the rotating plate 7199 is pulled to rotate, and the rotating plate 7199 rotates to pull the supporting bar 71912 to rotate. The supporting bar 71912 rotates and pulls the flip plate 71913 to rotate around the linkage rod 73. During the rotation of the flip plate 71913, it touches the blocking rod 71911 and rotates by itself. When the flip plate 71913 continues to rotate and no longer touches the blocking rod 71911, the flip plate 71913 returns to its original position with the cooperation of the torsion spring and throws out the adsorbed carbon particles on the flip plate 71913, so as to achieve the purpose of flipping the adsorbed carbon particles, so that the adsorbed carbon particles and the polluted air have sufficient contact, thereby further improving the polluted air treatment function.
