Description

Technical Field

[0001] This invention relates to the field of fire extinguisher bottle welding technology, specifically to a longitudinal seam welding device for fire extinguisher bottle processing. Background Technology

[0002] A fire extinguisher is a portable fire-fighting tool filled with different types of extinguishing agents such as dry powder, carbon dioxide, foam, and water-based agents. It is suitable for extinguishing initial fires in different scenarios. For example, dry powder fire extinguishers can deal with fires involving flammable liquids, gases, and electrical equipment; carbon dioxide fire extinguishers are suitable for fires involving precision instruments and archives; foam fire extinguishers are mostly used for fires involving flammable oils; and water-based fire extinguishers are suitable for fires involving solid materials, liquids, and electrical materials. The fire extinguisher bottle is the core pressure vessel of the fire extinguisher. It is mainly made of high-strength steel (such as high-quality carbon steel and alloy steel) or aluminum alloy, and has good pressure resistance and impact resistance. The processing of fire extinguisher bottles usually involves rolling steel plates and then welding them longitudinally to form a cylindrical structure. Then, the two ends of the cylindrical structure are welded and closed to form the bottle bottom and bottle mouth.

[0003] When welding rolled steel plates, if the steel plates are not fixed, they are easily affected by external forces and shake, which can cause the weld seam and the welding path to be misaligned, affecting the welding effect. Therefore, we have proposed a welding equipment for the longitudinal seam of the fire extinguisher bottle body. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a welding device for longitudinal seams of fire extinguisher cylinders, including a medium-sized bottom plate, an arc-shaped support column fixedly connected to the outer side of the medium-sized bottom plate, a vertical electric slide rail fixedly connected to the top of the medium-sized bottom plate, a T-shaped side slider slidably connected to one side of the vertical electric slide rail, a welding device fixedly connected to the side of the T-shaped side slider away from the vertical electric slide rail, a vertical fixing plate fixedly connected to the top of the medium-sized bottom plate, an annular claw fixedly connected to one side of the vertical fixing plate, a cap-type pressing device fixedly connected to the top of the vertical fixing plate, and an internal heat dissipation device penetrating and fixedly connected to the top of the medium-sized bottom plate.

A rectangular fixing plate is fixedly connected to the end of the rotary spring away from the convex sleeve plate. A central bearing round rod is fixedly connected to the side of the rectangular fixing plate near the rotary spring. A circular cover plate is fixedly connected to one side of the convex sleeve plate. The rotary force of the rotary spring drives the circular cover plate to apply pressure to the top of the coiled steel plate, so that the coiled steel plate is pressed and fixed and not easy to shake. An external annular claw is fixedly connected to the bottom of the circular cover plate, and a rectangular sliding hole is opened on the top of the circular cover plate.

[0006] Multiple arc-shaped support columns are provided, and the multiple arc-shaped support columns are distributed on both sides of the medium-sized bottom plate. Two annular claws are provided, and the two annular claws are distributed on one side of the vertical fixed plate.

[0007] The bottom of the rectangular fixing plate is fixedly connected to the top of the vertical fixing plate, and the convex sleeve is fitted onto the central bearing round rod and is rotatably connected to the central bearing round rod through a bearing.

[0008] The sealing-type pressing device also includes a circular handwheel. A threaded rod is threaded through and connected to one side of the circular handwheel. Both ends of the threaded rod are rotatably connected to fixed angle plates via rotating bolts. A circular threaded sleeve block is sleeved on the outside of the threaded rod and threaded to it. A rectangular slider is fixedly connected to the bottom of the circular threaded sleeve block. An arc-shaped pressure block is fixedly connected to the bottom of the rectangular slider block. By pushing the inner side of the coiled steel plate with the arc-shaped pressure block, the coiled steel plate is clamped and fixed between the external annular claw and the arc-shaped pressure block.

[0009] The bottom of the fixed angle plate is fixedly connected to the top of the circular cover plate. Two circular threaded sleeves are provided, and the two circular threaded sleeves are symmetrically distributed on both sides of the threaded rod located on the circular handwheel. The outer side of the rectangular slider is slidably connected to the inner wall of the rectangular sliding hole.

[0010] Furthermore, the internal heat dissipation device includes a vertical long air pipe, the bottom of which is connected to a high-pressure air pump. A flow-guiding exhaust mechanism is fixedly connected to the outside of the vertical long air pipe. Ventilation holes are provided on the outside of the vertical long air pipe, through which cooling gas is ejected to cool the interior of the rolled steel plate. A fixing block is fixedly connected to the outside of the vertical long air pipe, and an arc-shaped diverter plate is fixedly connected to the side of the fixing block away from the vertical long air pipe. The gas ejected from the ventilation holes... The airflow diffuses outwards along the arc surface of the curved diverter plate, while another portion passes through the vent holes and directly contacts the rolled steel plate, ensuring consistent heat dissipation across all areas within the rolled steel plate. Ventilation holes are located on the outer side of the curved diverter plate. A top-penetrating round rod is rotatably connected to the top of the vertical long air pipe. A circular sleeve block (first and second) is fitted and fixedly connected to the outer side of the top-penetrating round rod. A bottom-connecting round block is fixedly connected to the bottom of the top-penetrating round rod. A condenser tube is fixedly connected to the bottom of the vertical long gas pipe. A second fixed circular block is fixedly connected to the outer side of the condenser tube. An arc-shaped baffle is fixedly connected to the side of the second fixed circular block away from the condenser tube. The opening and closing state of the vent hole is adjusted by setting a rotatable arc-shaped baffle on the inner wall of the vertical long gas pipe, so that welding slag and dust from the outside will not enter the interior of the vertical long gas pipe and accumulate when the gas does not spray out of the vent hole. The bottom of the vertical long gas pipe passes through the medium-sized bottom plate and is fixedly connected to the medium-sized bottom plate. The top of the high-pressure gas pump is connected to the medium-sized bottom plate.

[0011] Furthermore, the flow-guiding exhaust mechanism includes an annular pad with an arc-shaped vent hole on its outer side. By setting the annular pad with the arc-shaped vent hole at the bottom of the coiled steel plate, the gas inside the coiled steel plate can be discharged in time without pressurizing the inside of the coiled steel plate. An arc-shaped air guide plate is fixedly connected to the inner side of the annular pad, and an inwardly inclined air guide hole is opened on the inner side of the arc-shaped air guide plate. The gas ejected from the vent hole near the bottom of the vertical long air pipe flows along the inner side of the arc-shaped air guide plate. Part of the gas flows along the arc-shaped path to the position of the arc-shaped vent hole, and part of the gas enters the inner side. The slanted air guide holes are directed downwards to the surface of the medium-sized bottom plate, allowing all areas of the medium-sized bottom plate surface to be treated by blowing away debris. The bottom of the annular pad is fixedly connected to the top of the medium-sized bottom plate. The side of the arc-shaped air guide plate away from the annular pad is fixedly connected to the outside of the vertical long air pipe.

Multiple inner slanted air guide holes are provided, and the multiple inner slanted air guide holes are distributed on the inside of the arc-shaped air guide plates.

[0012] This invention provides a welding device for the longitudinal seam of a fire extinguisher bottle. It has the following advantages:

[0013] 1. The cylinder longitudinal seam welding equipment for fire extinguisher processing uses a circular cover plate to press and fix the top of the steel plate by the rotational force of a rotary spring, preventing the steel plate from shaking due to external forces during welding, which would cause misalignment between the weld and the welding machine and affect the welding effect. Multiple ventilation holes on the surface of the vertical long air pipe are used to cool and dissipate heat inside the rolled steel plate, preventing the temperature from gradually rising during long-term welding and causing the steel plate to easily deform. Multiple arc-shaped ventilation holes are opened on the outside of the annular pad to facilitate gas discharge, preventing the gas continuously ejected from the ventilation holes from accumulating inside the rolled steel plate and continuously increasing pressure, which would affect the welding process.

[0014] 2. The longitudinal seam welding equipment for fire extinguisher cylinders is equipped with a cap-type pressing device. The circular cap plate is pressed and fixed to the top of the steel plate by the rotational force of the rotary spring, preventing the steel plate from shaking due to external forces during welding, which would cause the weld to misalign with the welder and affect the welding effect. The flat setting of the bottom surface of the convex sleeve plate allows the convex sleeve plate to rotate to its maximum limit when perpendicular to the vertical fixed plate, preventing the convex sleeve plate from being affected by the rotational force of the rotary spring and causing the circular cap plate to rotate excessively, which would cause the rolled steel plate to tilt and affect the welding process. The curved pressure block pushes and fixes the rolled steel plate between the external ring claw and the curved pressure block, preventing the pressed and fixed rolled steel plate from being easily affected by external forces and causing circumferential rotation, which would cause the longitudinal weld to deviate from the welder and affect the welding effect.

[0015] 3. The longitudinal seam welding equipment for the fire extinguisher cylinder is equipped with an internal heat dissipation device. Multiple vent holes on the surface of the vertical long air pipe cool the interior of the coiled steel plate, preventing the steel plate from gradually warming up and deforming during prolonged welding. An arc-shaped diverter plate outside the vent holes disperses the gas throughout the coiled steel plate, preventing uneven heating and affecting the welding effect. Square vent holes on the arc-shaped diverter plate allow some of the diverted gas to flow directly to the interior of the coiled steel plate, preventing uneven heating at the point where the interior of the steel plate aligns with the vent holes. The rotating arc-shaped baffle seals the vent holes, preventing weld slag and dust from entering the vertical long air pipe and becoming difficult to handle when not using jet cooling.

[0016] 4. The longitudinal seam welding equipment for the fire extinguisher cylinder is equipped with a flow-guiding exhaust mechanism. Multiple arc-shaped vent holes are opened on the outside of the annular pad to facilitate gas discharge, preventing the gas continuously ejected from the vent holes from accumulating inside the rolled steel plate and continuously increasing pressure, which would affect the welding process. The inner inclined surface of the inner inclined vent hole guides the gas downward to the surface of the medium-sized base plate and blows the accumulated welding slag to the outside of the arc-shaped vent hole for discharge. This prevents the welding slag and dust that fall off during the welding process from accumulating on the medium-sized base plate and being difficult to handle. The arc-shaped vent plate and the inner inclined vent hole disperse the gas ejected from the vent hole to various parts inside the annular pad, preventing the gas ejected from the vent hole from only cleaning the welding slag in a part of the top area of ​​the medium-sized base plate and making it difficult to clean thoroughly.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-4 This invention provides a welding device for longitudinal seams of fire extinguisher cylinders, comprising a medium-sized bottom plate 1, an arc-shaped support column 2 fixedly connected to the outer side of the medium-sized bottom plate 1, a vertical electric slide rail 3 fixedly connected to the top of the medium-sized bottom plate 1, a T-shaped side slider 4 slidably connected to one side of the vertical electric slide rail 3, a welder 5 fixedly connected to the side of the T-shaped side slider 4 away from the vertical electric slide rail 3, a vertical fixing plate 6 fixedly connected to the top of the medium-sized bottom plate 1, a ring-shaped claw 7 fixedly connected to one side of the vertical fixing plate 6, a cap-type pressing device 8 fixedly connected to the top of the vertical fixing plate 6, and an internal heat dissipation device 9 penetrating and fixedly connected to the top of the medium-sized bottom plate 1.

[0028] The sealing type pressing device 8 includes a convex sleeve plate 801. Rotary springs 802 are fixedly connected to both sides of the convex sleeve plate 801. A rectangular fixing plate 803 is fixedly connected to the end of the rotary spring 802 away from the convex sleeve plate 801. A central bearing round rod 804 is fixedly connected to the side of the rectangular fixing plate 803 close to the rotary spring 802. A circular cover plate 805 is fixedly connected to one side of the convex sleeve plate 801. An external annular claw 806 is fixedly connected to the bottom of the circular cover plate 805. A rectangular sliding hole 807 is opened on the top of the circular cover plate 805.

[0029] Multiple arc-shaped support columns 2 are provided, and the multiple arc-shaped support columns 2 are distributed on both sides of the medium-sized bottom fixed plate 1. Two ring-shaped claws 7 are provided, and the two ring-shaped claws 7 are distributed on one side of the vertical fixed plate 6.

[0030] The bottom of the rectangular fixing plate 803 is fixedly connected to the top of the vertical fixing plate 6, and the convex sleeve plate 801 is sleeved on the central bearing round rod 804 and is rotatably connected to the central bearing round rod 804 through a bearing.

[0031] The sealing-type pressing device 8 also includes a circular handwheel 808. A threaded rod 809 is threaded through and connected to one side of the circular handwheel 808. Both ends of the threaded rod 809 are rotatably connected to fixed angle plates 810 through rotating bolts. A circular threaded sleeve block 811 is sleeved on the outside of the threaded rod 809 and threadedly connected to it. A rectangular slider 812 is fixedly connected to the bottom of the circular threaded sleeve block 811. An arc-shaped pressing block 813 is fixedly connected to the bottom of the rectangular slider 812.

[0032] The bottom of the fixed angle plate 810 is fixedly connected to the top of the circular cover plate 805. Two circular threaded sleeves 811 are provided, and the two circular threaded sleeves 811 are symmetrically distributed on both sides of the threaded rod 809 located on the circular handwheel 808. The outer side of the rectangular slider 812 is slidably connected to the inner wall of the rectangular sliding hole 807. In use, push the cap-type pressing device 8 upward until the cap-type pressing device 8 is flush with the vertical fixed plate 6, then insert the coiled steel plate into the annular claw 7, and press the steel plate... The weld seam is aligned with the welder 5, and then the push on the capping pressure device 8 is released. At this time, the capping pressure device 8 will cover the top of the rolled steel plate to prevent it from shaking or rotating due to external forces. Then, the T-shaped side slider 4 is driven by the vertical electric slide rail 3 to move the welder 5 on one side in the longitudinal path. As the T-shaped side slider 4 moves longitudinally, the welder 5 performs longitudinal weld seam welding on the steel plate. At the same time, the internal heat dissipation device 9 is used to cool the inside of the rolled mesh plate.

[0033] After the coiled steel plate is inserted into the inner side of the annular claw 7, the rotary spring 802 drives the convex sleeve 801 to rotate. As the convex sleeve 801 rotates, it drives the circular cover plate 805 on one side to rotate until its bottom contacts the top of the steel plate. Simultaneously, the rotary spring 802 applies pressure to the top of the steel plate through the rotational force of the circular cover plate 805. The circular cover plate 805 is then pressed and fixed to the top of the steel plate by the rotational force of the rotary spring 802. The convex sleeve 801 stops rotating when its bottom surface contacts the top of the vertical fixing plate 6, and will not continue to rotate. The maximum rotation limit is achieved when the convex sleeve 801 is perpendicular to the vertical fixing plate 6 due to the planar design of its bottom surface. Then, turn the handwheel to drive the threaded rod 809 to rotate. When the threaded rod 809 rotates, it engages with the outer circular threaded sleeve 811. Under the engagement and limitation of the rectangular sliding hole 807, the circular threaded sleeve 811 engages with the threaded rod 809 and moves away from the circular handwheel 808. When the circular threaded sleeve 811 moves, it drives the bottom rectangular slider 812 to move. The movement of the rectangular slider 812 drives the bottom arc-shaped pressure block 813 to move. When the arc-shaped pressure block 813 moves to contact the inner side of the rolled steel plate, it pushes it. The pushing of the arc-shaped pressure block 813 fixes the rolled steel plate between the outer ring claw 806 and the arc-shaped pressure block 813.

[0034] Please see Figures 5-8This invention provides a welding device for the longitudinal seam of a fire extinguisher bottle: an internal heat dissipation device 9 includes a vertical long air pipe 901, the bottom of which is connected to a high-pressure air pump 902, a flow-guiding exhaust mechanism 903 fixedly connected to the outside of the vertical long air pipe 901, a ventilation hole 904 opened on the outside of the vertical long air pipe 901, and a fixing block 905 fixedly connected to the outside of the vertical long air pipe 901, the fixing block 905 being located away from the vertical long air pipe 901. An arc-shaped diverter plate 906 is fixedly connected to one side of the 1. A square ventilation hole 907 is opened on the outer side of the arc-shaped diverter plate 906. A top-penetrating round rod 908 is rotatably connected through the top of the vertical long air pipe 901. A circular sleeve block 909 is sleeved and fixedly connected to the outer side of the top-penetrating round rod 908. A circular sleeve block 910 is sleeved and fixedly connected to the outer side of the top-penetrating round rod 908. A bottom-connecting round block 911 is fixedly connected to the bottom of the top-penetrating round rod 908. The bottom of the bottom-connecting round block 911... A condenser pipe 912 is fixedly connected. A second fixed circular block 913 is fixedly connected to the outside of the condenser pipe 912. An arc-shaped baffle 914 is fixedly connected to the side of the second fixed circular block 913 away from the condenser pipe 912. The bottom of the vertical long air pipe 901 passes through the intermediate base plate 1 and is fixedly connected to the intermediate base plate 1. The top of the high-pressure air pump 902 is fixedly connected to the bottom of the intermediate base plate 1. The bottom of the flow-guiding exhaust mechanism 903 is fixedly connected to the top of the intermediate base plate 1. (Ventilation is provided.) Multiple round holes 904 are provided, and the multiple round ventilation holes 904 are distributed on the outside of the vertical long air pipe 901. Multiple square ventilation holes 907 are provided, and the multiple square ventilation holes 907 are symmetrically distributed on the outside of the arc-shaped diverter plate 906 at the same horizontal line as the round ventilation holes 904. The top of the arc-shaped baffle 914 is fixedly connected to the bottom of the bottom connecting round block 911. Three arc-shaped baffles 914 are provided, and the three arc-shaped baffles 914 are distributed on the bottom of the bottom connecting round block 911.

[0035] The flow-guiding exhaust mechanism 903 includes an annular pad 9031. An arc-shaped vent hole 9032 is provided on the outer side of the annular pad 9031. An arc-shaped air guide plate 9033 is fixedly connected to the inner side of the annular pad 9031. An inwardly inclined air guide hole 9034 is provided on the inner side of the arc-shaped air guide plate 9033. The bottom of the annular pad 9031 is fixedly connected to the top of the intermediate base plate 1. The side of the arc-shaped air guide plate 9033 away from the annular pad 9031 is fixedly connected to the outer side of the vertical long air pipe 901. Multiple arc-shaped vent holes 9032 are provided, distributed on the outer side of the annular pad 9031. Three arc-shaped air guide plates 9033 are provided, distributed on the inner side of the annular pad 9031. Multiple inwardly inclined air guide holes 9034 are provided, and these multiple inwardly inclined air guide holes 9034 are distributed inside the arc-shaped air guide plate 9033. During use, when the welder 5 welds the longitudinal seam of the rolled steel plate, high-pressure air pump 902 fills the vertical long air pipe 901 with gas. After entering the vertical long air pipe 901, the gas contacts the condenser pipe 912 for cooling. The cooled gas gradually fills the interior of the vertical long air pipe 901 and is ejected from the vent hole 904. The cold gas ejected from the vent hole 904 contacts the arc-shaped diverter plate 906 and disperses along the arc-shaped diverter plate 906 to both sides. Part of the gas dispersed along the arc-shaped path of the arc-shaped diverter plate 906 diffuses outwards, and part passes through the vent hole 907 directly into the rolled steel plate. Laterally flowing, the gas cools the interior of the coiled steel plate through multiple ventilation holes 904 on the surface of the vertical long air pipe 901. An arc-shaped diverter plate 906, located outside the ventilation holes 904, disperses the gas throughout the interior of the coiled steel plate. Square ventilation holes 907 on the surface of the arc-shaped diverter plate 906 facilitate the direct guidance of some of the diverted gas to the inner side of the coiled steel plate. Gas ejected from the ventilation holes 904 near the bottom of the vertical long air pipe 901 comes into contact with the flow-guiding exhaust mechanism 903 and is guided outwards by the flow-guiding exhaust mechanism 903. When the coiled steel plate is not being welded and does not require jet cooling, rotating the circular sleeve 909 drives the top-penetrating rod 908 to rotate, which in turn drives the bottom... The bottom connecting round block 911 rotates, causing the bottom arc-shaped baffle 914 to rotate. When the arc-shaped baffle 914 rotates to the position of the vent hole 904, it blocks it. The rotation of the arc-shaped baffle 914 completely seals the vent hole 904. The gas ejected from the vent hole 904 near the bottom of the vertical long air pipe 901 comes into contact with the arc-shaped air guide plate 9033 and flows along the arc-shaped path of the air guide plate 9033. A portion of the gas flowing along the surface of the arc-shaped air guide plate 9033 is directly discharged from the arc-shaped vent hole 9032. Multiple arc-shaped vent holes 9032 are provided on the outside of the annular pad 9031 to facilitate gas discharge. Another portion of the gas enters the inner inclined air guide hole 9034.The gas flows downwards through the arc-shaped vent plate 9033 under the guidance of the inwardly inclined vent hole 9034. The inwardly inclined surface of the vent hole 9034 directs the gas downwards towards the surface of the medium-sized bottom plate 1, blowing accumulated welding slag to the outside of the arc-shaped vent hole 9032 for discharge. The arc-shaped vent plate 9033 and the inwardly inclined vent hole 9034 disperse the gas ejected from the vent hole 904 to various parts inside the annular pad 9031.

[0036] When using this invention, push the capping pressing device 8 upwards until it is flush with the vertical fixing plate 6. Then, insert the rolled steel plate into the annular claw 7 and align the weld seam of the steel plate with the welder 5. Then, release the push on the capping pressing device 8. At this time, the capping pressing device 8 will cover and press the top of the rolled steel plate to prevent it from shaking or rotating due to external forces. Then, the vertical electric slide rail 3 drives the T-shaped side slider 4 to move the welder 5 on one side in a longitudinal path. As the T-shaped side slider 4 moves longitudinally, the welder 5 performs longitudinal seam welding on the weld seam of the steel plate. At the same time, the internal heat dissipation device 9 cools and dissipates heat inside the rolled mesh plate.

[0037] After the coiled steel plate is inserted into the inner side of the annular claw 7, the rotary spring 802 drives the convex sleeve 801 to rotate. When the convex sleeve 801 rotates, it drives the circular cover plate 805 on one side to rotate to the position where the bottom contacts the top of the steel plate. At the same time, the rotary spring 802 uses its rotational force to make the circular cover plate 805 press against the top of the steel plate. The circular cover plate 805 is pressed and fixed to the top of the steel plate by the rotational force of the rotary spring 802. The convex sleeve 801 stops rotating when its bottom surface contacts the top of the vertical fixing plate 6. The maximum rotation limit of the convex sleeve 801 is when its bottom surface is perpendicular to the vertical fixing plate 6, thanks to the planar setting of its bottom surface. Then, the handwheel is turned to drive the threaded... When rod 809 rotates, it engages with the outer circular threaded sleeve 811. Under the engagement and limitation of the rectangular sliding hole 807, the circular threaded sleeve 811 moves away from the circular handwheel 808. This movement drives the bottom rectangular slider 812, which in turn moves the bottom arc-shaped pressure block 813. When the arc-shaped pressure block 813 reaches contact with the inner side of the rolled steel plate, it pushes against it. The pressure from the arc-shaped pressure block 813 fixes the rolled steel plate between the outer ring claw 806 and the arc-shaped pressure block 813. When the welder 5 welds the longitudinal weld seam of the rolled steel plate, the high-pressure air pump 9... 02. Gas is introduced into the vertical long gas pipe 901. After entering the vertical long gas pipe 901, the gas comes into contact with the condenser pipe 912 for cooling. The cooled gas gradually fills the interior of the vertical long gas pipe 901 and is ejected from the vent hole 904. The cold gas ejected from the vent hole 904 comes into contact with the arc-shaped diverter plate 906 and flows to both sides along the arc-shaped diverter plate 906. Part of the gas flowing to both sides along the arc-shaped diverter plate 906 diffuses to the surroundings, and part of the gas flows directly into the inner side of the coiled steel plate through the vent hole 907. The multiple vent holes 904 on the surface of the vertical long gas pipe 901 cool and dissipate heat inside the coiled steel plate. The arc-shaped diverter plate 906 set outside the vent hole 904 disperses the gas to Throughout the interior of the coiled steel plate, ventilation holes 907 are provided on the surface of the arc-shaped diverter plate 906 to facilitate the direct diversion of some of the gas to the inner side of the coiled steel plate. Gas ejected from the ventilation holes 904 near the bottom of the vertical long air pipe 901 comes into contact with the guide-type exhaust mechanism 903 and is guided outwards by the mechanism. When the coiled steel plate is not being welded and does not require jet-type heat dissipation, rotating the circular sleeve block 909 causes the top-penetrating circular rod 908 to rotate. The rotation of the top-penetrating circular rod 908 causes the bottom connecting circular block 911 to rotate. The rotation of the bottom connecting circular block 911 causes the bottom arc-shaped baffle 914 to rotate. When the arc-shaped baffle 914 rotates to the position of the ventilation hole 904, it blocks it.The rotation of the arc-shaped baffle 914 covers and seals the vent hole 904. Gas ejected from the vent hole 904 near the bottom of the vertical long air pipe 901 contacts the arc-shaped air guide plate 9033 and flows along its arc-shaped path. A portion of the gas flowing along the surface of the arc-shaped air guide plate 9033 is directly discharged through the arc-shaped vent hole 9032. Multiple arc-shaped vent holes 9032 are provided on the outer side of the annular pad 9031 to facilitate gas discharge. Additionally, a portion... The gas enters the inwardly inclined vent 9034 and, guided by the inwardly inclined vent 9034, flows downward through the arc-shaped vent plate 9033. The inwardly inclined surface of the inwardly inclined vent 9034 directs the gas downward towards the surface of the medium-sized bottom plate 1, and blows the accumulated welding slag to the outside of the arc-shaped vent 9032 for discharge. The arc-shaped vent plate 9033 and the inwardly inclined vent 9034 disperse the gas ejected from the vent hole 904 to various parts of the annular pad 9031.
