Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0021] Embodiments of the present utility model:
[0022] A production line dust removal and ventilation system comprises a shell 1, and the shell 1 is installed on a robot welding production line (the robot welding production line is already a prior art, and this application will not repeat it in detail), an exhaust duct 2 is installed on the top of the shell 1, and it should be noted that: the interior of the exhaust duct 2 is divided into an air inlet area a, a first channel b and a second channel c, the first channel b and the second channel c are separated by a partition 6, and a plurality of filter screens 5 are installed equidistantly in the first channel b and the second channel c, the filter screens 5 are activated carbon filters, and the top and bottom of the partition 6 are fixedly connected to the inner top wall and the inner bottom wall of the exhaust duct 2 respectively, the air inlet area a is located at one end of the first channel b and the second channel c, an exhaust fan 3 is installed inside the air inlet area a, and through the setting of the exhaust fan 3, the smoke generated during welding can be drawn into the air inlet area a, and the air inlet area a, the first channel b and the second channel c are connected to the air inlet area a. A closing door 4 is rotatably installed at the position where the first channel b and the second channel c are connected. The setting of the closing door 4 can close the first channel b or the second channel c. If the closing door 4 is closed to the first channel b, the smoke in the air inlet area a can enter the second channel c, and the smoke is purified by the filter 5 in the second channel c. When the closing door 4 is closed to the second channel c, the smoke in the air inlet area a can enter the first channel b, and the smoke is purified by the filter 5 in the first channel b. A hinge shaft 7 is fixed on the top of the closing door 4, and a second motor 8 is fixed on the top end of the hinge shaft 7 passing through the exhaust pipe 2. The second motor 8 is preferably a servo motor. The setting of the second motor 8 can drive the closing door 4. A sealing sleeve (not shown in the figure) is fixed to the end of the closing door 4 away from the hinge shaft 7, and the setting of the sealing sleeve can play a sealing role.
[0023] Specifically, the exhaust fan 3 includes an exhaust pipe 31 with openings at both ends. The outer surface of the exhaust pipe 31 is fixed on the outer shell 1 and the exhaust duct 2. A mounting frame 32 is fixed inside the exhaust pipe 31, and a first motor 33 is rotatably mounted on the top of the mounting frame 32. The output end of the first motor 33 passes through the mounting frame 32 and is equipped with a rotating disk 34, and a plurality of fan blades 35 are equidistantly fixed on the circumferential surface of the rotating disk 34. The exhaust fan 3 is provided to change the air, and the smoke generated by the robot welding production line can be extracted, so that fresh air from the outside can enter the outer shell 1, reducing the harm caused to the workers by the smoke generated during welding. Filter covers 36 are installed at the openings at both ends of the exhaust fan 3. The filter cover 36 is provided to filter and reduce the entry of larger impurities into the exhaust pipe 31.

[0025] If the robot welding production line welds the workpiece, smoke will be generated. At this time, the first motor 3 can be turned on. The output of the first motor 33 drives the rotating disk 34 to rotate at high speed, so that the rotating disk 34 drives the multiple fan blades 35 to rotate at high speed, so that the smoke generated during welding can be drawn into the air inlet area a, and can be discharged through the first channel b or the second channel c, and the smoke is purified by the filter 5 in the first channel b or the filter 5 in the second channel c.

[0027] If the filter 5 in the second channel c needs to be cleaned or replaced due to blockage, the air inlet of the second channel c is blocked in the same manner as above, so that the smoke and dust in the air inlet area a enters the first channel b and is processed by the filter 4 in the first channel b, and then the filter 5 in the second channel c is cleaned and replaced.
