Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and specifically relates to a TIG welding equipment for a dust removal cloth bag support skeleton. Background Art

[0002] The dust removal cloth bag skeleton is an important component in the dust collector. It is mainly used to support and fix the dust removal cloth bag to ensure that the cloth bag can maintain a stable shape during the dust removal process and effectively capture dust;

[0003] Among them, the dust removal cloth bag skeleton is mainly composed of a top cover, ring circles and longitudinal bars, and a bottom plate. During the production process of the dust removal cloth bag, since the top cover and the bottom plate are directly provided finished parts, the ring circles and the longitudinal bars need to be pre-welded into a rib cage first, and then the two ends of the rib cage are respectively assembled and welded with the top cover and the bottom plate. After the assembly welding is cooled, it can be formed into a finished product of the dust removal cloth bag support skeleton after grinding and surface anti-corrosion treatment.

[0004] Referring to a skeleton processing and welding device for a dust removal cloth bag disclosed in the patent application with the publication number of CN114523233A, through the setting of the docking mechanism, the distance between the two support blocks can be conveniently adjusted by controlling the second motor, and the electromagnet can fix the connecting base and the connecting nozzle, so as to realize the docking between the skeleton and the connecting base and the connecting nozzle. The third motor drives the docked skeleton, connecting base and connecting nozzle to rotate, and the cylinder drives the connecting rod to stretch and contract, so that the connecting rod drives the welding head to move, thereby realizing the welding of the skeleton, which speeds up the work efficiency and improves the practicability of the device;

[0005] After comprehensively analyzing the above patents, the following defects are obtained:

[0006] At present, most of the welding equipment for the dust removal cloth bag support skeleton adopts the conventional method of welding the longitudinal bars at the end of the rib cage and the bottom plate. Since there are multiple longitudinal bars distributed in a ring in the rib cage, only one longitudinal bar can be welded to the bottom plate before welding the welds at other positions in turn. It is impossible to carry out welding operations on multiple welds simultaneously, resulting in an increase in welding time. Moreover, during the welding process, the rib cage needs to be continuously flipped to adjust the positions of multiple welds relative to the welding torch one by one, increasing the welding difficulty;

[0007] 2) Since the temperature difference between the welding area and the whole of the dust removal cloth bag support skeleton is relatively large, direct cold welding is extremely likely to cause an increase in welding stress and strain rate, resulting in cracks at the welding position and reducing the welding quality.

[0008] Therefore, the present invention proposes a TIG welding equipment for a dust removal cloth bag support skeleton to solve the above problems. Summary of the Invention

[0009] In view of the deficiencies in the prior art, the present invention provides an argon arc welding device for a dust bag support frame, which solves the problem that the current dust bag support frame welding equipment can only weld one of the longitudinal reinforcements and the chassis before welding the welds at other positions in turn, and is unable to weld multiple welds at the same time, resulting in increased welding time. In addition, the reinforcement cage needs to be continuously turned over during the welding process, and the positions of multiple welds relative to the welding gun need to be adjusted one by one, which increases the difficulty of welding. The temperature difference between the welding area and the dust bag support frame as a whole is large, and direct cold welding can easily lead to increased welding stress and strain rate, causing cracks at the welding position and reducing the welding quality.

The position of the studs is locked with the mounting plate through nuts.

[0023] Further, the dust removal cloth bag support skeleton includes a rib cage. A top cover and a tray are respectively welded at both ends of the rib cage. Multiple strip-shaped welding areas are formed after the rib cage and the tray are welded.

[0024] The present invention provides a TIG welding device for a dust removal cloth bag support skeleton. Compared with the prior art, the following beneficial effects are achieved:

[0025] 1. A TIG welding device for a dust removal cloth bag support skeleton can drive a plurality of bevel gears to rotate synchronously by arranging an inclined tooth disc, so as to realize the effect of synchronously adjusting the positions of a plurality of cross sliders II, and further achieve the purpose of synchronously increasing or decreasing the distance between the TIG welding gun tips, so as to adapt to the welding work of dust removal cloth bag support skeletons with different outer diameters; secondly, since the initial position of the TIG welding gun tip is a known value, according to the set rule, that is, when the pointer moves a distance of one scale wire groove, the distance between adjacent TIG welding gun tips increases or decreases by one millimeter. Therefore, based on the reference of the scale wire groove, the position of the TIG welding gun can be accurately adjusted to ensure the welding precision of the strip-shaped welding area between the dust removal rib cage and the tray.

[0026] 2. An argon arc welding device for a dust removal bag support skeleton. By setting a driving mechanism, this mechanism is used in cooperation with the welding mechanism, and the two form a linkage during the welding process. During the rotation of the welding mechanism, the arc-shaped driving plate can be used to push the lifting rod to move downward evenly, enabling the argon arc welding gun to move evenly along the long strip-shaped welding area and achieving the effect of continuous and stable welding; secondly, the arc-shaped driving plate and the disc are designed as a split type, and the arc-shaped driving plate with a corresponding radian size can be selected and replaced according to the longitudinal height of the long strip-shaped welding area. Each arc-shaped driving plate can drive the argon arc welding gun to descend by a fixed height value, that is, this height value is adapted to the height of the long strip-shaped welding area of the dust removal bag support skeleton, ensuring that after the lifting rod slides along the bottom of the arc-shaped driving plate, the argon arc welding gun can continuously move from the top to the bottom of the long strip-shaped welding area, realizing the continuous welding of multiple long strip-shaped welding areas; secondly, the arc surface of the arc-shaped driving plate is a continuous and smooth curved surface, which can drive the argon arc welding gun to descend smoothly and continuously. Compared with the welding method where manual control of the welding speed is impossible, the present invention can ensure that the weld seam is more continuous and flat, which is beneficial to improving the welding quality.

[0027] 3. An argon arc welding device for a dust removal bag support skeleton. By setting an exhaust gas treatment mechanism, the effect of driving the exhaust gas treatment mechanism to operate can be achieved synchronously during the welding process. Since the gear and the gear ring are meshed and connected, the gear can be driven to rotate by the gear ring when the turntable rotates, thereby achieving the effect of driving the fan blade to rotate rapidly. The suction force generated when the fan blade rotates can suck the harmful smoke generated during the welding process into the purification cylinder, realizing the purification treatment of the welding smoke and avoiding the scattering of the welding smoke everywhere and endangering the health of the staff; secondly, the welding smoke that has been purified and has a relatively high temperature can be blown through the nozzle onto the surface of the dust removal bag support skeleton to be welded that has been clamped. The high-temperature welding smoke can heat the dust removal bag support skeleton, achieving the preheating effect before welding and avoiding the situation that the weld seam position deforms and cracks due to the thermal stress generated during the welding process and the residual stress after cooling because the temperature of the dust removal bag support skeleton is relatively low before welding, thereby reducing the welding quality; furthermore, the exhaust gas treatment mechanism converts part of the rotational force of the turntable during the welding process into the driving force for the rotation of the fan blade, thereby providing power for the work of the exhaust gas treatment mechanism and eliminating the need to separately set a driving device for the exhaust gas treatment mechanism, making the structure simpler and facilitating subsequent maintenance and repair work.

[0028] 4. An argon arc welding device for a dust removal cloth bag support skeleton can provide stable supporting force when two welding mechanisms are performing welding operations. When welding the next pair of dust removal cloth bag supports, the two welding devices can be synchronously driven by the second servo motor to rotate a set angle, completing the switching of the welding mechanism positions, so that they are in new welding positions, ensuring that the two welding mechanisms and the next pair of dust removal cloth bag support skeletons are in one-to-one correspondence, facilitating the rapid welding of the next pair of dust removal cloth bag support skeletons, and thus improving the welding efficiency.

Detailed implementation manners

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0048] As Figures 1 - 17 , the present invention provides four technical solutions: an argon arc welding device for the support skeleton of a dust removal cloth bag, specifically including the following embodiments:

[0049] Embodiment 1: As Figures 1 - 7, 16, 17, An argon arc welding device for a dust removal cloth bag support skeleton, comprising a welding table 1, an operation window 2 opened on the front surface of the welding table 1, and a dust removal cloth bag support skeleton 5. A servo motor 1 is fixedly arranged inside the welding table 1. The output shaft of the servo motor 1 rotates through the welding table 1 and is fixedly connected to a turntable 3. A plurality of exhaust gas through-hole areas 4 are evenly opened on the top of the turntable 3. At the central position of the top of each exhaust gas through-hole area 4, a positioning component 6 for limiting the position of the dust removal cloth bag support skeleton 5 to facilitate subsequent welding operations is fixedly arranged. At positions corresponding to the plurality of positioning components 6 at the bottom of the turntable 3, a plurality of exhaust gas treatment mechanisms 7 for purifying welding fumes and recycling the heat of the welding fumes are arranged. A toothed ring 8 for cooperating with the exhaust gas treatment mechanism 7 to complete the welding fume treatment work is fixedly arranged on the top of the welding table 1. A support mechanism 9 is arranged at the central position of the top of the turntable 3. Welding mechanisms 10 for performing multi-point synchronous welding on the dust removal cloth bag support skeleton 5 are arranged on both sides of the outer wall of the support mechanism 9. And a driving mechanism 11 for driving the welding mechanisms 10 to complete synchronous welding actions is arranged above the support mechanism 9. The driving mechanism 11 includes a disc 111 fixedly arranged at the bottom of the carrier and mounting through-slots 112 symmetrically opened on both sides of the top of the disc 111. A driving unit for pushing the welding mechanism 10 to lift is detachably arranged inside the mounting through-slots 112. The driving unit includes a mounting plate 113 connected in the mounting through-slots 112 by fastening bolts and stud mounting through-holes 114 opened on both sides of the top of the mounting plate 113. An arc-shaped driving plate 115 is arranged below the mounting plate 113. Studs 116 adapted to the stud mounting through-holes 114 are fixedly arranged on both sides of the top of the arc-shaped driving plate 115. The studs 116 are locked in position with the mounting plate 113 through nuts. The dust removal cloth bag support skeleton 5 includes a rib cage 51. A top cover 52 and a tray 53 are respectively welded at both ends of the rib cage 51. A plurality of strip-shaped welding areas 54 are formed after the rib cage 51 and the tray 53 are welded. The exhaust gas through-hole area 4 includes a plurality of exhaust gas through-holes distributed in a ring shape. The plurality of exhaust gas through-holes are all internally connected to the corresponding exhaust gas treatment mechanism 7. All the electrical equipment in the present invention is connected to an external power supply through carbon brushes to ensure stable power supply during the rotation of the turntable 3. The positioning component 6 includes a telescopic rod 61 and an electromagnetic iron plate 62 fixedly arranged at the top end of the telescopic rod 61. Two limiting columns 63 are detachably arranged on the side wall of the electromagnetic iron plate 62 to ensure that the welding positions of the plurality of welding points of the dust removal cloth bag support skeleton 5 correspond to the welding positions of the welding mechanism 10 one by one.The telescopic rod 61 can be manually adjusted in height to adapt to the dust bag support frame 5 of different lengths within a certain range. The distance between the two limit columns 63 is just adapted to the distance between two adjacent longitudinal ribs in the dust bag support frame 5. When the limit column 63 is located between two adjacent longitudinal ribs in the dust bag support frame 5, the position of each welding point in the dust bag support frame 5 corresponds one by one to the position of the argon arc welding gun 1014 in the welding mechanism 10; the distance between the two limit columns 63 can be adjusted according to the distance between two adjacent longitudinal ribs in the rib cage 51.

[0050] Embodiment 2: Figures 8 - 9 The main difference between this embodiment and the first technical solution is that: an argon arc welding device for a dust bag support frame, the exhaust gas treatment mechanism 7 includes a purification component 71 arranged at the bottom of the turntable 3 and a preheating component arranged on one side of the purification component 71 for spraying air to the dust bag support frame 5, the purification component 71 and the preheating component are connected by a connecting pipe 72, which is used to transport the air purified by the purification component 71 to the preheating component; the preheating component includes an annular tube 73 fixedly arranged above the turntable 3 by a mounting bracket, and a plurality of nozzles 74 connected to the interior of the annular tube 73 are evenly fixedly arranged on the outer wall of the annular tube 73. The purification assembly 71 includes a purification cartridge 711 detachably arranged at the bottom of the turntable 3 by bolts, a cover plate connected to the inner wall of the purification cartridge 711 by threads, and a plurality of air inlets 712 evenly arranged on the top of the cover plate. A filter element 713 for purifying welding fumes is fixedly arranged inside the purification cartridge 711. A transmission 714 is connected to the bottom of the purification cartridge 711 by a flange. A gear 715 meshing with the gear ring 8 is fixedly arranged on the input shaft of the transmission 714. The output shaft of the transmission 714 rotates through the purification cartridge 711 and is fixedly arranged. There are fan blades 716. The transmission 714 is used to accelerate the power input by the input shaft and output it through the output shaft. Multiple nozzles 74 are arranged around the positioning component 6, which can spray air from multiple angles to the clamped dust bag support frame 5. When the sprayed air flow is purified flue gas, the air carries heat, which can preheat the dust bag support frame 5 to be welded to prevent the dust bag support frame 5 from having a low temperature before welding, resulting in thermal stress generated during welding and residual stress after cooling, which causes the weld position to deform and crack. The transmission 714 is a known prior art and has been widely used. Its internal structure and working principle will not be described in detail here.

[0051] Embodiment 3: Figure 10, the main difference between this embodiment and the second technical solution is as follows: an argon arc welding device for a dust removal cloth bag support skeleton, the support mechanism 9 includes a first transmission shaft 91 fixedly arranged at the center of the top of the turntable 3 through a flange and a motor box 92 fixedly arranged at the top end of the first transmission shaft 91. A second servo motor is fixedly arranged inside the motor box 92. The output shaft of the second servo motor rotates through the motor box 92 and is connected with a connecting shaft 93 through a coupling. A locking mechanism 94 for locking or releasing the output shaft of the second servo motor is fixedly arranged at the top of the motor box 92. A bearing frame 95 is connected to the outer wall of the motor box 92 through a flange. A second transmission shaft 96 fixedly connected to the top end of the connecting shaft 93 is rotatably arranged inside the bearing frame 95. Support arms 97 for installing a welding mechanism 10 are fixedly arranged on both sides of the outer wall of the second transmission shaft 96. A cross-shaped through groove is formed inside the support arm 97. The locking mechanism 94 is a prior art, and its internal structure will not be described in detail here. When the second servo motor stops working, the locking device in the locking mechanism 94 can lock its output shaft to prevent it from rotating; when the second servo motor is turned on, the locking mechanism 94 can disengage the locking device from the shaft surface, and the motor shaft can rotate freely. The locking mechanism 94 can effectively control the movement of the motor shaft to ensure that the motor will not rotate accidentally when it stops, improving safety and stability. The locking device is the core component of the motor shaft locking mechanism 94, which is used to realize the locking function of the motor shaft and realizes the locking by clamping the motor shaft.

[0052] Embodiment 4: As Figures 11 - 15, the main difference between this embodiment and the third technical solution is: an argon arc welding device for the dust removal cloth bag support skeleton, the welding mechanism 10 includes a welding component for welding the dust removal cloth bag support skeleton 5 and a hoisting unit for driving the welding component to lift and lower; the hoisting unit includes a first cross-shaped slider 101 slidably arranged inside the cross-shaped through groove and a lifting rod 102 slidably penetrating through the first cross-shaped slider 101. The position of the first cross-shaped slider 101 and the cross-shaped through groove is locked by a fastening bolt. A time-delay switch 103 for controlling the start or stop of the welding component is fixedly arranged at the top of the lifting rod 102, and a connecting frame 105 is fixedly arranged at the bottom end of the lifting rod 102. A limiting ring is fixedly sleeved on the outer wall of the lifting rod 102 above the first cross-shaped slider 101, and a spring 104 is slidably sleeved on the outer wall of the lifting rod 102 between the limiting ring and the first cross-shaped slider 101. The welding component includes a bearing plate 106 fixedly arranged at the bottom end of the connecting frame 105 and a plurality of cross-shaped sliding grooves 107 uniformly opened at the bottom of the bearing plate 106. A plurality of strip-shaped through grooves 108 corresponding to the positions of the cross-shaped sliding grooves 107 one by one and communicating with the inside thereof are uniformly opened at the top of the bearing plate 106. A transmission groove 109 is opened at the central position of the bearing plate 106. A welding unit for welding one of the welding positions of the dust removal cloth bag support skeleton 5 is arranged inside each cross-shaped sliding groove 107; the welding unit includes a screw rod 1010 rotatably arranged inside the cross-shaped sliding groove 107 and a bevel gear 1011 fixedly arranged at one end of the screw rod 1010 and located inside the transmission groove 109. A second cross-shaped slider 1017 is threadedly sleeved on the outer wall of the screw rod 1010. The second cross-shaped slider 1017 is slidably arranged inside the cross-shaped sliding groove 107. A pointer 1012 and an argon arc welding gun 1014 are respectively fixedly arranged at the top and bottom of the second cross-shaped slider 1017. A scale wire groove 1013 for indicating the moving distance of the pointer 1012 is opened at the top of the bearing plate 106 and on one side of the strip-shaped through groove 108. A helical gear disk 1015 simultaneously meshed with a plurality of bevel gears 1011 is rotatably arranged inside the transmission groove 109. An adjusting rod is fixedly arranged at the top of the helical gear disk 1015. The top end of the adjusting rod rotatably penetrates through the bearing plate 106 and is fixedly provided with an adjusting knob 1016. The time-delay switch 103 is used to control the working set time of a plurality of argon arc welding guns 1014 at the same time, and the delay time can be adjusted according to specific requirements. The time-delay switch 103 and the argon arc welding gun 1014 are electrically connected by a wire. A plurality of operation openings are uniformly opened on the outer wall of the connecting frame 105 for facilitating the staff to rotate and adjust the adjusting knob 1016.After the adjustment knob 1016 is used, a fastening bolt or other component is required to lock its position to prevent rotation. The initial position of the second cross slider 1017 is a known value. When the second cross slider 1017 is in the initial position, the distance between adjacent gun heads of the multiple tungsten inert gas (TIG) welding torches 1014 corresponding to the bottom of the second cross sliders 1017 is also a known value. The distance from the top of the turntable 3 to the position of the gun head of the TIG welding torch 1014 in the initial position state is also a known set value. Moreover, the central position formed by the gun heads of the multiple TIG welding torches 1014 is opposite to the central position of the positioning component 6. After the dust removal cloth bag support skeleton 5 is clamped, its center of gravity and the center position of the positioning component 6 are on the same vertical line. By replacing the arc-shaped driving plate 115 with different known heights, the distance that the gun head of the TIG welding torch 1014 descends can be changed. Adjustment is made with reference to the initial position value of the gun head of the TIG welding torch 1014 and the size of the dust removal cloth bag support skeleton 5 to be welded, ensuring that after the adjustment is completed, the positions of the gun heads of the multiple TIG welding torches 1014 can just match the positions of the four strip-shaped welding areas 54 of the dust removal cloth bag support skeleton 5 to be welded. And for every distance that the pointer 1012 moves one scale groove 1013, the distance between adjacent gun heads of the TIG welding torches 1014 increases or decreases by one millimeter.

[0053] During use, first adjust the height of the positioning component 6 according to the height of the dust removal cloth bag support skeleton 5 to be welded. The height of the telescopic rod 61 needs to be adjusted to a height suitable for the height of the dust removal cloth bag support skeleton 5, and then the position of the telescopic rod 61 is locked with bolts. Then, the cage 51 part of the dust removal cloth bag support skeleton 5 is sleeved outside the positioning component 6. One end of the cage 51 is placed on the top of the turntable 3, and then the tray 53 is placed on the top of the cage 51. At this time, the bottom of the tray 53 is just placed on the top of the electromagnetic iron plate 62, and it is ensured that the two limit posts 63 are located between two adjacent longitudinal bars in the cage 51. Since the longitudinal bars are evenly distributed, after the limit posts 63 are located between any two longitudinal bars, the weld positions of the cage 51 and the tray 53 correspond one by one to the positions of the TIG welding torches 1014. After the electromagnetic iron plate 62 is powered on, the adsorption and fixation of the tray 53 can be completed. Thus, the position locking of the dust removal cloth bag support skeleton 5 is completed, and the same operation is carried out in the same way at other positions of the turntable 3 according to the installation method of the dust removal cloth bag support skeleton 5 as described above;

[0054] Next, adjust the welding mechanism 10 that can adapt to the welding size according to the size of the dust removal cloth bag support skeleton 5 to be welded. When adjusting: Rotate the adjustment knob 1016 to drive the adjustment rod to rotate, so that the helical gear disk 1015 synchronously drives a plurality of bevel gears 1011 to rotate, and a plurality of cross sliders two 1017 move away from or close to the helical gear disk 1015 synchronously, increasing or decreasing the distance between the gun heads of the argon arc welding guns 1014 synchronously. Since the initial position of the gun heads of the argon arc welding guns 1014 is a known value, according to the set rule, that is, for every distance that the pointer 1012 moves one scale wire groove 1013, the distance between adjacent gun heads of the argon arc welding guns 1014 increases or decreases by one millimeter. Therefore, at this time, based on the reference of the scale wire groove 1013, the position of the argon arc welding guns 1014 is precisely adjusted until the positions of the gun heads of the argon arc welding guns 1014 and the plurality of strip-shaped welding areas 54 on the dust removal cloth bag support skeleton 5 can meet the welding requirements; then lock the position of the adjustment knob 1016 to end the adjustment of the welding mechanism 10;

[0055] Next, according to the size specification of the current dust removal bag support frame 5, the corresponding drive mechanism 11 is replaced accordingly, so that the drive mechanism 11 can push the argon arc welding gun 1014 in the welding mechanism 10 to descend to a position corresponding to the long strip-shaped welding area 54 of the dust removal bag support frame 5 to be welded. The replacement process of the drive mechanism 11 is as follows: Remove the nut between the locking stud 116 and the mounting plate 113, take off the arc-shaped drive plate 115, and then connect the arc-shaped drive plate 115 of the corresponding size to the mounting plate 113 again. Similarly, the installation method of the drive mechanism 11 on the other side is the same as the above method. At this time, the replacement work of the drive mechanism 11 is completed. When welding the dust removal bag support frame 5, the control box installed on the welding table 1 is used to control the start of the first servo motor. The initial positions of the two welding mechanisms 10 are opposite to the positions of two of the dust removal bag support frames 5. The first servo motor rotates 180 degrees at a low speed and uniformly, and the turntable 3 and the support mechanism 9 rotate synchronously. When the lifting rod 102 just touches the arc-shaped drive plate 115, the delay switch 103 located at the top of the lifting rod 102 for controlling the argon arc welding gun 1014 is triggered to turn on, and the argon arc welding gun 1014 starts to work. When the lifting rod 102 continues to slide along the bottom of the arc-shaped drive plate 115, the argon arc welding gun 1014 moves downward at a uniform and low speed along the connection area between the rib cage 51 and the tray 53, that is, the top of the long strip-shaped welding area 54, and the long strip-shaped welding area 54 is welded. When the lifting rod 102 slides to the bottom end of the arc-shaped drive plate 115, that is, when the first servo motor rotates 90 degrees, the argon arc welding gun 1014 just moves to the bottom end of the long strip-shaped welding area 54, and the long strip-shaped welding area 54 is completely welded. The first servo motor continues to rotate 90 degrees, and the lifting rod 102 continues to slide along the bottom of the arc-shaped drive plate 115. The lifting rod 102 is pushed by the elastic force of the spring 104 to move upward uniformly until it returns to the initial position. At this time, the welding work of the dust removal bag support frames 5 in two of the positions is completed. When welding the dust removal bag support frames 5 in the other two positions, the preset program controls the second servo motor to drive the transmission shaft two 96 to rotate 90 degrees, and the positions of the two welding mechanisms 10 are switched to the positions opposite to the other two un-welded dust removal bag support frames 5. Then the locking mechanism locks the output shaft of the second servo motor, and then continuing the above welding operation process can complete the welding work again;

[0056] During the welding process, the turntable 3 drives multiple waste gas treatment mechanisms 7 to work. The gear 715 rotates driven by the gear ring 8, and the transmission 714 accelerates the input rotational force and drives the fan blade 716 to rotate rapidly. The suction force sucks the welding fumes into the intake port 712. The harmful substances in the welding fumes are filtered by the filter element 713 and then transported to the annular pipe 73 through the connecting pipe 72. The annular pipe 73 is located outside the dust removal cloth bag support frame 5 that has been clamped and is to be welded. Since the welding fumes carry a relatively high amount of heat, the hot air is evenly blown onto the surface of the dust removal cloth bag support frame 5 through the nozzle 74 to heat the dust removal cloth bag support frame 5. At the same time, the nozzles 74 in the waste gas treatment mechanisms 7 at the positions where welding is not being performed can also eject normal temperature air. Since the nozzles 74 are arranged in an annular array and are all oriented towards the long strip-shaped welding area 54, the blown air can form a barrier around the dust removal cloth bag support frame 5 being welded to prevent the welding fumes from flying around, and the welding fume purification process ends.
