Description

Technical Field

[0001] This invention relates to the field of stainless steel barrel welding, specifically an automatic stainless steel barrel welding machine. Background Technology

[0002] Stainless steel buckets are made of stainless steel. Because stainless steel is resistant to corrosion from weak corrosive media such as air, steam, and water, as well as chemical corrosive media such as acids, alkalis, and salts, stainless steel buckets are highly durable. Buckets made entirely of stainless steel also have fire-resistant properties and are sturdy and durable. Since the production process of stainless steel buckets usually requires welding the various components together, welding machines are needed.

[0003] Commonly used welding machines consist of a welding device and a welding table. The welding device needs to be held manually and the welding operation is performed manually by welding technicians. In the production process of stainless steel drums, it is usually necessary to weld the various components of the stainless steel drum together. During the welding process of the drum lid and the drum body, the staff needs to control the stainless steel drum and rotate the drum lid and the drum body to achieve the welding of the stainless steel drum, thereby increasing the workload of the staff.

[0004] Therefore, an automatic welding machine for stainless steel barrels is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: An automatic stainless steel barrel welding machine of this invention includes a base; a first electric push rod is fixedly connected to the top of the base, and a top plate is fixedly connected to the moving end of the first electric push rod; a welding device is provided on the rear side of the base; a support roller is rotatably connected to the top of the base; a first motor is fixedly connected to the right side of the base; the output end of the first motor is fixedly connected to the support roller; a first groove is formed inside the top plate; a second motor is fixedly connected to the side of the top plate; a first screw is fixedly connected to the output end of the second motor; the first screw is located inside the first groove and rotatably connected to the first groove; the surface of the first screw... A first movable plate is threadedly connected to a first groove. The first movable plate is slidably connected to a first groove. A third motor is fixedly connected to the side of the first movable plate. A second screw is fixedly connected to the output end of the third motor. The second screw is rotatably connected to the first movable plate. A trapezoidal plate is threadedly connected to the surface of the second screw and slidably connected to the first movable plate. A second movable plate is fixedly connected to the inner side of the first groove and slidably connected to the trapezoidal plate. A first through hole is formed inside the second movable plate, and the first screw is slidably connected to the first through hole. An L-shaped connecting frame is fixedly connected to the side of the second movable plate, and an arc-shaped clamping plate is rotatably connected to the inner side of the L-shaped connecting frame. A push rod is fixedly connected to the surface of the trapezoidal clamp plate. The push rod works in conjunction with the trapezoidal plate. A first push plate is fixedly connected to the side of the first moving plate. A limit device is provided at the bottom of the top plate. This step moves the first moving plate, which in turn moves the first push plate, pushing the steel drum from one end to facilitate its movement to connect with the lid. This allows the welding device to weld the steel drum and lid more quickly. The bottom of the steel drum is supported by support rollers on both sides, which rotate the steel drum. The top plate moves the second moving plate, which in turn moves the arc-shaped clamp plate, adjusting the position of the arc-shaped clamp plate that limits the steel drum. Then, the trapezoidal plate moves, and the inclined surfaces on both sides of the trapezoidal plate push the steel drum. The rotation of the rod drives the arc-shaped clamping plate to rotate, clamping the steel barrel at the bottom. This, combined with the first push plate, limits the movement of the steel barrel, ensuring stability during welding and rotation. The side of the first moving plate has a drive assembly for the trapezoidal plate. The first moving plate needs to drive the first push plate to adjust its position, supporting the bottom of the barrel and pushing it forward. If the first moving plate drives the first push plate to limit one end of barrels of different lengths, it will simultaneously move the trapezoidal plate away from the push rod. Therefore, an assembly for moving the trapezoidal plate needs to be installed on the side of the first moving plate to facilitate its movement towards the push rod. Adjusting the position of the second moving plate further shortens the distance between the push rod and the trapezoidal plate.

[0007] Preferably, the limiting device includes a first cylinder, the top plate is fixedly connected to the first cylinder, the moving end of the first cylinder is fixedly connected to a moving frame, the inner side of the moving frame is rotatably connected to a first limiting shaft, and the bottom of the moving frame is slidably connected to a second push plate via a slide rail. In this step, the first cylinder drives the first limiting shafts on both sides to move up and down. When the surfaces of the first limiting shafts on both sides are in contact with two points on the surface of the bucket lid, the bucket lids of different sizes are limited, making the bucket lids more stable when rotating. The second push plate can push the bucket lids to move towards the steel bucket, and in conjunction with the first push plate, it supports one end of the bucket body and pushes the bucket body to move, so that the bucket lids can be connected to the bucket body more quickly.

[0008] Preferably, the base has a second groove inside, a push frame is rotatably connected inside the second groove, a feeding shaft is rotatably connected to the top of the push frame, a first gear is fixedly connected to the side of the push frame, a fifth motor is fixedly connected inside the second groove, and a second gear is fixedly connected to the output end of the fifth motor. The second gear meshes with the first gear. In this step, the fifth motor drives the second gear to rotate, which in turn drives the push frame to rotate through the first gear, pushing up the feeding shaft. The feeding shaft can then push down the steel drum on top of the support roller, facilitating the feeding of the steel drum.

[0009] Preferably, the sides of both the first and second push plates are rotatably connected with ball bearings, and the inside of the arc-shaped clamp is rotatably connected with limiting rollers, and several limiting rollers are provided. This step, by setting ball bearings, allows the ball bearings to rotate when the first and second push plates are in contact with the steel drum, reducing the resistance when the steel drum rotates. By setting several limiting rollers, the limiting rollers limit the steel drum while not hindering its rotation.

[0010] Preferably, a first return spring is fixedly connected to the bottom of the second movable plate. Several first return springs are provided, one end of which is fixedly connected to the arc-shaped clamping plate. A limit rod is fixedly connected to the bottom of the second movable plate. This step involves setting the first return spring, which is located on the outside of the arc-shaped clamping plate. This facilitates replacement when the first return spring is damaged. When the trapezoidal plate separates from the push rod, the first return spring can pull the arc-shaped clamping plate to reset. The limit rod can limit the arc-shaped clamping plate when it is pulled to reset by the first return spring, preventing the arc-shaped clamping plate from driving the push rod to reset too much. When the surface of the arc-shaped clamping plate is in contact with the bottom of the limit rod, the arc-shaped clamping plate stops rotating, making it easier for the push rod to be pushed again by the trapezoidal plate.

[0011] Preferably, a rotating shaft is rotatably connected to the side of the first movable plate via a torsion spring. A tension rope is wound around the surface of the rotating shaft. One end of the tension rope is fixedly connected to the rotating shaft, and the other end is fixedly connected to a trapezoidal plate. A turntable is fixedly connected to the side of the rotating shaft, and a push shaft is fixedly connected to the side of the turntable. A limit plate is fixedly connected to the side of the first movable plate. A sliding groove is formed on the inner side of the limit plate. A movable ring is slidably connected to the limit plate through the sliding groove. The push shaft is slidably connected to the movable ring. A fixed rod is fixedly connected to the bottom of the movable ring. A sliding rod is slidably connected inside the fixed rod. A second return spring is fixedly connected inside the fixed rod, and one end of the second return spring is connected to the sliding rod. The moving rod is fixedly connected, and a limit frame is fixedly connected to the side of the sliding rod. A second limit shaft is rotatably connected to the bottom of the limit frame. In this step, by setting a tension rope, when the trapezoidal plate moves, the tension rope can pull the rotating shaft to rotate. The rotating shaft drives the push shaft to rotate through the turntable. The push shaft pushes the moving ring to move through the limit plate. The moving ring pushes the second limit shaft to move downward through the fixed rod, the sliding rod and the second return spring, so that the second limit shaft limits the surface of the stainless steel barrel. When the stainless steel barrel rotates, it drives the two second limit shafts to rotate, increasing the stability of the end of the stainless steel barrel. When the trapezoidal plate moves towards the first moving plate, the torsion spring pulls the rotating shaft to reverse, so that it drives the second limit shaft to move upward and separate from the surface of the stainless steel barrel.

[0012] Preferably, a T-shaped limiting strip is fixedly connected to the side of the first movable plate, and a first limiting groove is opened inside the trapezoidal plate. The T-shaped limiting strip is slidably connected to the first limiting groove. This step can increase the stability of the movement of the trapezoidal plate through the T-shaped limiting strip and the first limiting groove, and at the same time limit the distance of movement of the trapezoidal plate.

[0013] Preferably, an exhaust fan is fixedly connected to the top of the top plate, a filter assembly is fixedly connected to the top of the top plate, and an opening is provided at the bottom of the top plate. The air inlet of the exhaust fan is connected to the opening through the filter assembly. A second cylinder is fixedly connected to the top of the top plate, and a wire brush is fixedly connected to the moving end of the second cylinder. This step can extract and filter the fumes generated during welding, reducing the pollution of welding fumes. By driving the wire brush to contact the surface of the steel barrel, the welded part of the steel barrel is cleaned, reducing the waste residue of the welded part.

[0014] Preferably, a telescopic rod is fixedly connected to the side of both the movable frame and the limiting frame, and a third return spring is fixedly connected to the side of both the movable frame and the limiting frame. A third limiting shaft is fixedly connected to the moving end of the telescopic rod, and one end of the third return spring is connected to the third limiting shaft. A transmission belt is rotatably connected to the surfaces of both the first and second limiting shafts. The third limiting shaft is located inside the transmission belt, and its surface is in contact with the transmission belt. This step, by moving the transmission belt, can limit the movement of stainless steel barrels with a diameter smaller than the distance between the first and second limiting shafts. By using the telescopic rod and the third return spring to pull the third limiting shaft, the top of the transmission belt is moved upward, increasing the tension of the transmission belt.

[0015] Preferably, a second limiting groove is provided on the side of the first groove, and a sliding rod is fixedly connected inside the first groove. Both the second limiting groove and the sliding rod are slidably connected to the first moving plate. This step uses the sliding rod to support and reinforce the first moving plate when it slides.

[0016] The advantages of this invention are:

[0017] 1. The automatic stainless steel drum welding machine of the present invention, by moving a first moving plate, which in turn moves a first push plate, pushes the steel drum from one end, making it easier to move to connect with the lid, allowing the welding device to weld the steel drum and lid more quickly. Support rollers on both sides support the bottom of the steel drum and rotate it. A top plate moves a second moving plate, which in turn moves an arc-shaped clamping plate, adjusting the position of the arc-shaped clamping plate relative to the steel drum. Then, a trapezoidal plate moves, and the inclined surfaces on both sides of the trapezoidal plate push a push rod to rotate, which in turn rotates the arc-shaped clamping plate, thus welding the bottom of the steel drum... The steel drum is clamped and limited by the first push plate to ensure its stability during welding and rotation. The side of the first moving plate is equipped with a drive assembly for the trapezoidal plate. The first moving plate needs to drive the first push plate to adjust its position. The first push plate supports the bottom of the drum and pushes the drum body to move. If the first moving plate drives the first push plate to limit one end of the drum body of different lengths, it will simultaneously drive the trapezoidal plate away from the push rod. Therefore, it is necessary to install an assembly on the side of the first moving plate to drive the trapezoidal plate to move easily towards the push rod. In addition, by adjusting the position of the second moving plate, the distance between the push rod and the trapezoidal plate can be shortened.

[0018] 2. The automatic stainless steel barrel welding machine of the present invention uses a first cylinder to drive the first limiting shafts on both sides to move up and down, which can limit the barrel lids of different sizes, making the barrel lids more stable when rotating. The second push plate can push the barrel lids to move towards the steel barrel, so that the barrel lids can be connected to the steel barrels more quickly. Attached Figure Description

[0032] 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.

[0033] Specific implementation examples are given below.

[0034] Please see Figures 1 to 7As shown in the figure, an automatic stainless steel barrel welding machine according to an embodiment of the present invention includes a base 1; a first electric push rod 12 is fixedly connected to the top of the base 1, and a top plate 13 is fixedly connected to the moving end of the first electric push rod 12; a welding device 14 is provided on the rear side of the base 1; a support roller 15 is rotatably connected to the top of the base 1; a first motor 16 is fixedly connected to the right side of the base 1; the output end of the first motor 16 is fixedly connected to the support roller 15; a first groove 17 is provided inside the top plate 13; a second motor 18 is fixedly connected to the side of the top plate 13; a first screw 19 is fixedly connected to the output end of the second motor 18; the first screw 19 is located inside the first groove 17 and rotatably connected to the first groove 17; and a first thread is threaded onto the surface of the first screw 19. A movable plate 110 is slidably connected to a first groove 17. A third motor 111 is fixedly connected to the side of the first movable plate 110. A second screw 112 is fixedly connected to the output end of the third motor 111. The second screw 112 is rotatably connected to the first movable plate 110. A trapezoidal plate 113 is threadedly connected to the surface of the second screw 112. The trapezoidal plate 113 is slidably connected to the first movable plate 110. A second movable plate 116 is fixedly connected to the inner side of the first groove 17. The trapezoidal plate 113 is slidably connected to the second movable plate 116. A first through hole is opened inside the second movable plate 116. A first screw 19 is slidably connected to the first through hole. An L-shaped connecting bracket 117 is fixedly connected to the side of the second movable plate 116. An arc-shaped clamping plate 118 is rotatably connected to the inner side of the frame 117. A push rod 119 is fixedly connected to the surface of the arc-shaped clamping plate 118. The push rod 119 works in conjunction with the trapezoidal plate 113. A first push plate 120 is fixedly connected to the side of the first moving plate 110. A limit device 2 is provided at the bottom of the top plate 13. During operation, the top plate 13 is moved upward by several first electric push rods 12, and the bucket lid to be welded is placed on the left side of the welding device 14. The limit device 2 limits the bucket lid, and the steel bucket is placed on top of the two side support rollers 15, so that it is located on the right side of the welding device 14. The two side support rollers 15 support the steel bucket from the bottom of the steel bucket. Then the first electric push rods 12 move the top plate 13 downward, and the top plate 13 moves downward by moving the top plate 13 side. The structure of the surface is moved, bringing the arc-shaped clamping plate 118 closer to the top of the steel drum. The second motor 18 drives the first screw 19 to rotate, which in turn moves the first moving plate 110. The first moving plate 110 then moves the third motor 111 and the first push plate 120, causing the side of the first push plate 120 to abut against the side of the steel drum. When the first moving plate 110 moves the first push plate 120, the first push plate 120 pushes the steel drum towards the welding device 14, connecting the part of the steel drum to be welded to the drum lid. Then, the third motor 111 drives the second screw 112 to rotate, which in turn moves the trapezoidal plate 113 towards the push rod 119, causing the side of the trapezoidal plate 113 to contact the push rods 119 on both sides.When the push rod 119 rotates, it rotates at the bottom of the second moving plate 116, and the push rod 119 does not contact the bottom surface of the second moving plate 116. The arc-shaped clamping plate 118 is rotatably connected to the L-shaped connecting frame 117. Therefore, the arc-shaped clamping plate 118 can rotate around the point where it connects with the L-shaped connecting frame 117. When the side of the trapezoidal plate 113 contacts the push rods 119 on both sides, it can push the push rod 119 to rotate. The push rod 119 drives the arc-shaped clamping plate 118 to rotate around the connection part with the L-shaped connecting frame 117. The inner side of the arc-shaped clamp 118 contacts the surface of the steel drum, limiting the surface of the steel drum. The length from the fixed point of the arc-shaped clamp 118 and the push rod 119 to the side of the trapezoidal plate 113, plus the thickness of the arc-shaped clamp 118 itself, is less than the vertical distance between the top surface of the arc-shaped clamp 118 and the bottom surface of the trapezoidal plate 113, so as to reserve sufficient rotation space and prevent the drum from shaking when rotating. When the arc-shaped clamp 118 contacts the steel drum, the trapezoidal plate 113 cannot be pushed. The first motor 16 drives the support roller 15 to rotate, and the support rollers 15 on both sides move in the same direction. The rotation of the top plate causes the steel drum at the top to rotate, and the welding device 14 welds the steel drum. This step involves moving the first moving plate 110, which in turn moves the first push plate 120, pushing the steel drum from one end to facilitate its connection with the lid. This allows the welding device 14 to weld the steel drum and lid more quickly. The bottom of the steel drum is supported by the support rollers 15 on both sides, which also cause the steel drum to rotate. The top plate 13 then moves the second moving plate 116, which in turn moves the arc... The curved clamp 118 moves, adjusting its position to limit the steel drum. Then, the second screw 112 drives the trapezoidal plate 113 to move, preventing an increase in the distance between the trapezoidal plate 113 and the push rod 119, which would hinder the push rod 119's movement. The inclined surfaces on both sides of the trapezoidal plate 113 push the push rod 119 to rotate, which in turn drives the curved clamp 118 to rotate, clamping the bottom of the steel drum. This, combined with the first push plate 120, limits the steel drum's position, ensuring stability during welding and rotation.

[0035] Please see Figure 1 and Figure 8As shown, the limiting device 2 includes a first cylinder 21, a top plate 13 fixedly connected to the first cylinder 21, a moving frame 22 fixedly connected to the moving end of the first cylinder 21, a first limiting shaft 23 rotatably connected to the inner side of the moving frame 22, and a second push plate 24 slidably connected to the bottom of the moving frame 22 via a slide rail. During operation, when the bucket lid is placed above the support rollers 15 on both sides, the first cylinder 21 pushes the moving frame 22 downwards, which in turn pushes the first limiting shafts 23 and the second push plate 24 downwards. The second push plate 24 is positioned lower than the first limiting shafts 23 on both sides, causing the first limiting shafts 23 to move downwards until their surface contacts the surface of the bucket lid. The lid is positioned to a limit, while the second push plate 24 is located on one side of the lid. The second push plate 24 moves along the slide rail, pushing the lid towards the welding device 14 to connect it to one side of the steel drum. This step is achieved by the first cylinder 21 driving the first limiting shafts 23 on both sides to move up and down. The thickness of the lid needs to be greater than that of the first limiting shafts 23. When the surfaces of the first limiting shafts 23 on both sides are in contact with two points on the surface of the lid, lids of different sizes are limited, making the lid more stable when rotating. The second push plate 24 can push the lid towards the steel drum, and together with the first push plate 120, it supports one end of the drum body and pushes the drum body to move, allowing the lid to connect to the drum body more quickly.

[0036] Please see Figure 1 and Figure 9 As shown, the base 1 has a second groove 31 inside, and a pusher frame 32 is rotatably connected inside the second groove 31. A feeding shaft 33 is rotatably connected to the top of the pusher frame 32, and a first gear 34 is fixedly connected to the side of the pusher frame 32. A fifth motor 35 is fixedly connected inside the second groove 31, and a second gear 36 is fixedly connected to the output end of the fifth motor 35. The second gear 36 meshes with the first gear 34. During operation, when the steel drum is welded and needs to be removed, the first electric push rod 12 pushes the top plate 13 upward, which drives the moving frame 22 upward through the first cylinder 21. The moving frame 22 then drives the first limiting shaft 23 upward, causing it to... Separate from the surface of the bucket lid, then separate the arc-shaped clamp 118 from the surface of the steel bucket. Then, the fifth motor 35 drives the two second gears 36 at the output end to rotate, which in turn drives the first gear 34 to rotate. The first gear 34 drives the push frame 32 to rotate to one side, which in turn drives the two feeding shafts 33 at the top to rotate. The feeding shafts 33 push the steel bucket down. In this step, the fifth motor 35 drives the second gear 36 to rotate, which in turn drives the push frame 32 to rotate through the first gear 34, pushing up the feeding shafts 33. The feeding shafts 33 can push the steel bucket off the top of the support roller 15, making it easier to feed the steel bucket.

[0037] Please see Figures 1 to 8As shown, the sides of the first push plate 120 and the second push plate 24 are rotatably connected with ball bearings 41, and the inside of the arc-shaped clamping plate 118 is rotatably connected with limiting rollers 42, and several limiting rollers 42 are provided. During operation, when the first push plate 120 and the second push plate 24 move, they drive the ball bearings 41 to move, so that the surface of the ball bearings 41 contacts one end of the steel drum and the lid. When the arc-shaped clamping plate 118 moves, it drives the limiting rollers 42 to move, so that the surface of the limiting rollers 42 contacts the surface of the steel drum. When the steel drum and the lid rotate, they drive the ball bearings 41 and the limiting rollers 42 to rotate. This step, by setting the ball bearings 41, allows the ball bearings 41 to rotate when the first push plate 120 and the second push plate 24 are in contact with the steel drum, reducing the resistance when the steel drum rotates. By setting several limiting rollers 42, the limiting rollers 42 limit the steel drum while not hindering the rotation of the steel drum.

[0038] Please see Figure 4 and Figure 5 As shown, a first return spring 51 is fixedly connected to the bottom of the second moving plate 116. Several first return springs 51 are provided. One end of each first return spring 51 is fixedly connected to the arc-shaped clamping plate 118. A limit rod 52 is fixedly connected to the bottom of the second moving plate 116. During operation, when the trapezoidal plate 113 separates from the push rod 119, the top end of the first return spring 51 connects to the second moving plate 116. When the push rod 119 drives the arc-shaped clamping plate 118 to rotate, the side of the arc-shaped clamping plate 118 pulls the bottom end of the first return spring 51 to extend or retract. When the side of the trapezoidal plate 113 separates from the push rod 119, the first return spring 51 retracts, pulling the arc-shaped clamping plate 118 to rotate via its bottom end. The arc-shaped clamping plate 118 then drives the push rod 119 to reset, allowing the arc-shaped clamping plate 118 to clamp again. The arc-shaped clamping plate 118 resets around its connection point with the L-shaped connecting frame 117. When the arc-shaped clamping plate 118 clamps the barrel body, the surface of the arc-shaped clamping plate 118 will not contact the limiting rod 52. When the arc-shaped clamping plate 118 separates from the barrel body, the arc-shaped clamping plate 118 stops resetting rotation until its surface contacts the limiting rod 52. This step is achieved by setting a first reset spring 51, which is located on the outside of the arc-shaped clamping plate 118 for easy replacement if damaged. When the trapezoidal plate 113 separates from the push rod 119, the first reset spring 51 can pull the arc-shaped clamping plate 118 to reset. The limiting rod 52 can limit the arc-shaped clamping plate 118 when it is pulled back by the first reset spring 51, preventing the arc-shaped clamping plate 118 from driving the push rod 119 to reset rotation too much. When the surface of the arc-shaped clamping plate 118 is in contact with the bottom of the limiting rod 52, the arc-shaped clamping plate 118 stops rotating, making the position of the push rod 119 easy for the trapezoidal plate 113 to push it again.

[0039] Please see Figures 1 to 11As shown, a rotating shaft 61 is rotatably connected to the side of the first movable plate 110 via a torsion spring. A tension rope 62 is wound around the surface of the rotating shaft 61. One end of the tension rope 62 is fixedly connected to the rotating shaft 61, and the other end is fixedly connected to the trapezoidal plate 113. A turntable 63 is fixedly connected to the side of the rotating shaft 61, and a push shaft 64 is fixedly connected to the side of the turntable 63. A limiting plate 65 is fixedly connected to the side of the first movable plate 110. A groove is provided on the inner side of the limiting plate 65. A movable ring 66 is slidably connected to the limiting plate 65 through the groove. The push shaft 64 is slidably connected to the movable ring 66. A fixing rod 67 is fixedly connected to the bottom of the movable ring 66. A sliding rod 68 is slidably connected inside the fixing rod 67. A second... A return spring 69 is provided, and one end of the second return spring 69 is fixedly connected to the sliding rod 68. A limit frame 610 is fixedly connected to the side of the sliding rod 68, and a second limit shaft 611 is rotatably connected to the bottom of the limit frame 610. During operation, when the trapezoidal plate 113 moves toward the push rod 119, it drives the tension ropes 62 on both sides to move. The other end of the tension ropes 62 drives the rotating shaft 61 to rotate. The rotating shaft 61 drives the turntable 63 to rotate. The turntable 63 drives the push shaft 64 to rotate. The push shaft 64 drives the moving ring 66 to slide downward inside the limit plate 65. The moving ring 66 drives the fixed rod 67 to move downward. The fixed rod 67 pushes the second return spring 69 inside, causing it to drive the sliding rod 68 to move downward. 68 drives the limiting frame 610 to move downwards, which in turn drives the second limiting shaft 611 to move downwards, thus limiting the surface of the stainless steel barrel. When the trapezoidal plate 113 moves towards the first moving plate 110, the torsion spring pulls the rotating shaft 61 to rotate, causing the tension rope 62 to wrap around the surface of the rotating shaft 61. At the same time, the rotating shaft 61 drives the turntable 63 to rotate in the opposite direction, which in turn drives the push shaft 64 to rotate. The push shaft 64 pulls the moving ring 66 to move upwards, which in turn drives the fixed rod 67 to move. The fixed rod 67 drives the sliding rod 68 and the second return spring 69 to move, which in turn drives the limiting frame 610 to move upwards, causing the second limiting shaft 611 to separate from the stainless steel barrel. In this step, by setting up a tension rope 62, when the trapezoidal plate 113 moves, the tension rope 62 can pull the rotating shaft 61 to rotate. The rotating shaft 61 drives the push shaft 64 to rotate through the turntable 63. The push shaft 64 pushes the moving ring 66 to move through the limiting plate 65. The moving ring 66 pushes the second limiting shaft 611 to move down through the fixed rod 67, the sliding rod 68 and the second return spring 69, so that the second limiting shaft 611 limits the surface of the stainless steel barrel. When the stainless steel barrel rotates, it drives the two second limiting shafts 611 to rotate, increasing the stability of the end of the stainless steel barrel. When the trapezoidal plate 113 moves towards the first moving plate 110, the torsion spring pulls the rotating shaft 61 to reverse, so that it drives the second limiting shaft 611 to move up and separate from the surface of the stainless steel barrel.

[0040] Please see Figure 6 and Figure 7 As shown, a T-shaped limiting strip 71 is fixedly connected to the side of the first movable plate 110, and a first limiting groove 72 is provided inside the trapezoidal plate 113. The T-shaped limiting strip 71 is slidably connected to the first limiting groove 72. During operation, when the trapezoidal plate 113 moves, it slides on the surface of the T-shaped limiting strip 71. The distance the trapezoidal plate 113 moves is limited by the T-shaped limiting strip 71 and the first limiting groove 72. This step can increase the stability of the movement of the trapezoidal plate 113 by the T-shaped limiting strip 71 and the first limiting groove 72, and at the same time limit the distance the trapezoidal plate 113 moves.

[0041] Please see Figure 1 and Figure 8 As shown, an exhaust fan 81 is fixedly connected to the top of the top plate 13, and a filter assembly is fixedly connected to the top of the top plate 13. An opening 82 is provided at the bottom of the top plate 13. The air inlet of the exhaust fan 81 is connected to the opening 82 through the filter assembly. A second cylinder 83 is fixedly connected to the top of the top plate 13, and a wire brush 84 is fixedly connected to the moving end of the second cylinder 83. During operation, when the welding device 14 welds the steel drum, the exhaust fan 81 draws air from the bottom of the top plate 13 through the filter assembly and the opening 82 and filters the air. After welding is completed, the second cylinder 83 pushes the wire brush 84 down, so that the bottom surface of the wire brush 84 cleans the welded part of the steel drum. This step can draw and filter the fumes generated during welding, reducing the pollution of welding fumes. By driving the wire brush 84 to contact the surface of the steel drum, the welded part of the steel drum is cleaned, reducing the waste residue of the welding part.

[0042] Please see Figures 1 to 11As shown, telescopic rods 91 are fixedly connected to the sides of both the movable frame 22 and the limiting frame 610. Third return springs 92 are also fixedly connected to the sides of both the movable frame 22 and the limiting frame 610. A third limiting shaft 93 is fixedly connected to the moving end of the telescopic rod 91. One end of the third return spring 92 is connected to the third limiting shaft 93. A transmission belt 94 is rotatably connected to the surfaces of both the first limiting shaft 23 and the second limiting shaft 611. The third limiting shaft 93 is located inside the transmission belt 94, and its surface is in contact with the transmission belt 94. During operation, when the first limiting shaft 23 and the second limiting shaft 611 move, they drive the transmission belt 94 to move. When the first limiting shaft 23 and the second limiting shaft 611 limit the stainless steel barrel, they drive the transmission belt 94 to contact the stainless steel barrel. When the bucket rotates, it drives the transmission belt 94 to rotate on the surfaces of the first limiting shaft 23 and the second limiting shaft 611. The transmission belt 94 drives the first limiting shaft 23 and the second limiting shaft 611 to rotate. When the transmission belt 94 comes into contact with the stainless steel bucket, the surface of the stainless steel bucket pushes the ground of the transmission belt 94 upward to extend and retract. The telescopic rod 91 and the third return spring 92 pull the third limiting shaft 93 to move, pulling it from the inside of the transmission belt 94 and making the transmission belt 94 taut. This step, by driving the transmission belt 94 to move, can limit the stainless steel bucket whose diameter is smaller than the distance between the first limiting shaft 23 or the second limiting shaft 611. The telescopic rod 91 and the third return spring 92 pull the third limiting shaft 93 to move the top of the transmission belt 94 upward, increasing the tension of the transmission belt 94.

[0043] Please see Figure 1 As shown, a second limiting groove 101 is provided on the side of the first groove 17, and a slide rod 102 is fixedly connected inside the first groove 17. The second limiting groove 101 and the slide rod 102 are slidably connected to the first moving plate 110. This step uses the slide rod 102 to support and reinforce the first moving plate 110 when it slides.

[0044] Working principle: Several first electric actuators 12 drive the top plate 13 upward, placing the bucket lid to be welded on the left side of the welding device 14. The bucket lid is limited by the limiting device 2, placing the steel bucket on top of the two side support rollers 15, positioning it on the right side of the welding device 14. The two side support rollers 15 support the steel bucket from the bottom. Then, the first electric actuators 12 drive the top plate 13 downward, causing the structure on the side of the top plate 13 to move, bringing the arc-shaped clamping plate 118 closer to the top of the steel bucket. The second motor 18 drives the first screw 19 to rotate, which in turn drives the first moving plate 110 to move. The first moving plate 110 then drives the third motor 111 and the first push plate 12. The first moving plate 110 moves the first push plate 120 so that its side abuts against the side of the steel drum. When the first moving plate 110 moves the first push plate 120, the first push plate 120 pushes the steel drum toward the welding device 14, connecting the part of the steel drum to be welded with the drum lid. Then, the third motor 111 drives the second screw 112 to rotate, which in turn drives the trapezoidal plate 113 toward the push rod 119, so that the side of the trapezoidal plate 113 contacts the push rods 119 on both sides. When the push rod 119 rotates, it rotates at the bottom of the second moving plate 116, and the push rod 119 does not contact the bottom surface of the second moving plate 116. Meanwhile, the arc-shaped clamping plate 118 is rotatably connected to the L-shaped connecting frame 117, so the arc-shaped clamping plate 118 can be connected to the L-shaped connecting frame 117. The connecting point of the connecting frame 117 rotates around the center. When the side of the trapezoidal plate 113 contacts the push rods 119 on both sides, it can push the push rods 119 to rotate. The push rods 119 drive the arc-shaped clamping plate 118 to rotate around the connection part with the L-shaped connecting frame 117, so that the inner side of the arc-shaped clamping plate 118 contacts the surface of the steel drum, limiting the surface of the steel drum. The length from the fixed point of the arc-shaped clamping plate 118 and the push rod 119 to the side of the trapezoidal plate 113, plus the thickness of the arc-shaped clamping plate 118 itself, is less than the vertical distance between the top surface of the arc-shaped clamping plate 118 and the bottom surface of the trapezoidal plate 113, so as to reserve sufficient rotation space and prevent the drum from shaking when rotating. When the arc-shaped clamping plate 118 contacts the steel drum, the trapezoidal plate 11... 3. If it cannot be pushed, the first motor 16 drives the support roller 15 to rotate. The support rollers 15 on both sides rotate in the same direction, driving the top steel barrel to rotate. The steel barrel is welded by the welding device 14. When the barrel lid is placed above the support rollers 15 on both sides, the first cylinder 21 pushes the moving frame 22 to move down. The moving frame 22 pushes the first limiting shaft 23 and the second push plate 24 on both sides to move down. The second push plate 24 is lower than the first limiting shaft 23 on both sides. The first limiting shaft 23 moves down so that its surface contacts the surface of the barrel lid, limiting the barrel lid. At the same time, the second push plate 24 is located on one side of the barrel lid. The second push plate 24 moves through the slide rail, pushing the barrel lid to move towards the welding device 14, so that it connects with one side of the steel barrel.After the steel drum is welded, when it needs to be removed, the first electric actuator 12 pushes the top plate 13 upward, which in turn drives the moving frame 22 upward via the first cylinder 21. The moving frame 22 then drives the first limiting shaft 23 upward, separating it from the surface of the drum lid. This causes the arc-shaped clamping plate 118 to separate from the surface of the steel drum. Then, the fifth motor 35 drives the two second gears 36 at its output end to rotate, which in turn drives the first gear 34 to rotate. The first gear 34 then drives the pusher frame 32 to rotate to one side, which in turn drives the two top... The feeding shaft 33 rotates, pushing the steel drum down. When the first push plate 120 and the second push plate 24 move, they drive the ball bearing 41 to move, so that the surface of the ball bearing 41 contacts one end of the steel drum and the lid. When the arc-shaped clamping plate 118 moves, it drives the limiting roller 42 to move, so that the surface of the limiting roller 42 contacts the surface of the steel drum. When the steel drum and the lid rotate, they drive the ball bearing 41 and the limiting roller 42 to rotate. When the trapezoidal plate 113 separates from the push rod 119, the first return spring 51 can pull the arc-shaped clamping plate 118 to return to its original position. 18 drives the push rod 119 to reset, allowing the arc-shaped clamping plate 118 to clamp again. The arc-shaped clamping plate 118 rotates after resetting, and when its top contacts the limiting rod 52, it stops rotating, keeping the push rod 119 vertical. When the trapezoidal plate 113 separates from the push rod 119, the top of the first reset spring 51 connects to the second moving plate 116. When the push rod 119 drives the arc-shaped clamping plate 118 to rotate, the side of the arc-shaped clamping plate 118 pulls the bottom of the first reset spring 51 to extend and retract. When the side of the trapezoidal plate 113 contacts the push rod 119... When rod 119 separates, the first return spring 51 contracts, pulling the arc-shaped clamp 118 to rotate through its bottom end. The arc-shaped clamp 118 then drives the push rod 119 to reset, allowing the arc-shaped clamp 118 to clamp again. The arc-shaped clamp 118 resets and rotates around the connection point with the L-shaped connecting frame 117. When the arc-shaped clamp 118 clamps the barrel, the surface of the arc-shaped clamp 118 will not contact the limit rod 52. When the arc-shaped clamp 118 separates from the barrel, the arc-shaped clamp 118 stops resetting and rotating until its surface contacts the limit rod 52.When the trapezoidal plate 113 moves toward the push rod 119, it drives the tension ropes 62 on both sides to move. The other end of the tension ropes 62 drives the rotating shaft 61 to rotate, which in turn drives the turntable 63 to rotate. The turntable 63 drives the push shaft 64 to rotate, which in turn drives the moving ring 66 to slide downward inside the limiting plate 65. The moving ring 66 drives the fixed rod 67 to move downward, which in turn pushes the second return spring 69 inside, causing it to move the sliding rod 68 downward. The sliding rod 68 drives the limiting frame 610 to move downward, which in turn drives the second limiting shaft 611 to move downward. The second limiting shaft 611 limits the surface of the stainless steel barrel. When the trapezoidal plate 113 moves towards the first moving plate 110, the torsion spring pulls the rotating shaft 61 to rotate, causing the tension rope 62 to wrap around the surface of the rotating shaft 61. At the same time, the rotating shaft 61 drives the turntable 63 to rotate in the opposite direction. The turntable 63 drives the push shaft 64 to rotate, which in turn pulls the moving ring 66 to move upward. The moving ring 66 drives the fixed rod 67 to move, which in turn drives the sliding rod 68 and the second return spring 69 to move. The second return spring 69 drives the limiting frame 610 to move upward, causing it to move the second limiting shaft 610. Shaft 611 separates from the stainless steel drum; when the trapezoidal plate 113 moves, it slides on the surface of the T-shaped limiting strip 71, and the distance the trapezoidal plate 113 moves is limited by the T-shaped limiting strip 71 and the first limiting groove 72; when the welding device 14 welds the steel drum, the exhaust fan 81 draws air from the bottom of the top plate 13 through the filter assembly and the port 82 and filters the air; after welding is completed, the second cylinder 83 pushes the wire brush 84 down, so that the bottom surface of the wire brush 84 cleans the welded part of the steel drum; when the first limiting shaft 23 and the second limiting shaft 611 move, they drive the transmission belt 94 to move. When the first limiting shaft 23 and the second limiting shaft 611 limit the stainless steel barrel, they cause the transmission belt 94 to come into contact with the stainless steel barrel. When the stainless steel barrel rotates, it causes the transmission belt 94 to rotate on the surface of the first limiting shaft 23 and the second limiting shaft 611. The transmission belt 94 drives the first limiting shaft 23 and the second limiting shaft 611 to rotate. When the transmission belt 94 contacts the stainless steel barrel, the surface of the stainless steel barrel pushes the transmission belt 94 upwards, causing it to extend and retract. This, through the telescopic rod 91 and the third return spring 92, pulls the third limiting shaft 93 to move, pulling the transmission belt 94 from inside and tightening it.
