[0028] Four guide rods 194 are provided and distributed in a circular array with the rotating disk 191 as the center. One end of the guide rod 194 away from the spring 193 is rotatably connected to a ball 195 .

[0029] The process of automatic tank loading: In actual application, the pressure tank is divided into two symmetrical tank bodies before welding. A partition plate 1411 is provided in the middle position above the loading platform 141. The partition plate 1411 divides the loading platform 141 into two parts, the upper and lower tank bodies are placed respectively, and the tank bodies are neatly arranged. Two connecting plates 142 are also provided and are designed to be symmetrical with the partition plate 1411 as the center. Side baffles are provided on both sides of the loading platform 141 to limit the position of the tank body. The tank bodies are neatly stacked between the side baffles and the partition plate 1411. The top plane of the loading platform 141 adopts an inclined design, and the side close to the flip plate 12 is lower. Under the action of natural gravity, the tank body will roll to the side of the flip plate 12. A connecting plate 142 is provided on the side of the loading platform 141 close to the flip plate 12. The interior of the connecting plate 142 is connected to the shaft rod through a torsion spring 143, and the two ends of the shaft rod are distributed and penetrate the interior of the partition plate 1411 and the side baffle.

[0030] In the initial state, the connecting plate 142 is in an upward tilted state, and the connecting plate 142, the L-shaped plate 1441 and the pressing plate 1442 are of an integrally formed design, and the angle between the connecting plate 142 and the L-shaped plate 1441 is about 120 degrees. At this time, the bottom plate of the L-shaped plate 1441 away from the connecting plate 142 is in the same plane as the upper surface of the loading platform 141, and the pressing plate 1442 is hidden at the bottom of the loading platform 141, and the loading parts 144 are all in the through groove of the loading platform 141. The bottom ends and side end vertices of the first two cans on the upper surface of the loading platform 141 close to the flip plate 12 are in contact with the outer surfaces of the L-shaped plates 1441 on both sides.

[0031] In the initial state, the flip plate 12 is in an inclined state, and the angle between the flip plate 12 and the side plate 13 is about 100 degrees, wherein the lower surface of the side plate 13 is in contact with the hypotenuse of the bracket 17, playing a supporting role, and the adjacent sides of the side plate 13 and the flip plate 12 are all designed with hypotenuses. At this time, the hypotenuses of the side plate 13 and the flip plate 12 are completely in contact, and the flip plate 12 is supported by the bracket 17 on the side plate 13, and is also in a relatively fixed state. At this time, the central axis of the roller 16 and the rotating wheel 171 are on the same horizontal plane (the roller 16 and the rotating wheel 171 have the same radius), and the roller 16 is fixedly connected to the lower surface of the flip plate 12 through the connecting frame, and always moves with the flip plate 12, the gear rod 152 is inside the base 151, and the lifting plate 154 at the bottom of the gear rod 152 is at the lowest point at this time.

[0032] The rotating shaft inside the support frame 11 is connected through the driving base. After the driving base is started, it drives the rotating shaft to rotate counterclockwise. At the same time, the flip plate 12 fixedly connected to the rotating shaft rotates counterclockwise synchronously. The side of the flip plate 12 close to the loading platform 141 begins to press down. During this process, the bottom surface of the outer end of the flip plate 12 will contact the outer surface of the connecting plate 142. As the counterclockwise rotation angle of the flip plate 12 increases, the degree of pressing down of the connecting plate 142 increases, and the connecting plate 142 is forced to rotate clockwise around the shaft rod. The torsion spring 143 inside the connecting plate 142 is in a compressed state. Since the L-shaped plate 1441, the pressure plate 1442 and the connecting plate 142 are designed as an integrated whole, the L-shaped plate 1441 will rotate clockwise with the shaft rod as the axis.

[0033] The L-shaped plate 1441 moves upward from the through slot and drives the previous can body close to the flip plate 12 to tilt up. The center of gravity of the tank body that is in contact with the outer surface of the L-shaped plate 1441 is located above the loading platform 141 in the initial state; when the L-shaped plate 1441 starts to rotate, as the L-shaped plate 1441 is higher than the upper surface of the loading platform 141, the center of gravity of the tank body is located on the bottom plate of the L-shaped plate 1441 away from the connecting plate 142; the L-shaped plate 1441 continues to rotate in a "V-shape" with the opening upward, and the tank body is engaged inside the L-shaped plate 1441 until the flip plate 12 rotates to a specified position, and the bottom plate of the L-shaped plate 1441 away from the connecting plate 142 is in a vertical relationship with the loading platform 141, and the center of gravity of the tank body is located above the top plate of the L-shaped plate 1441 close to the connecting plate 142, and the top plate of the L-shaped plate 1441 is in an inclined state, and the side close to the flip plate 12 is lower, and the tank body moves toward the upper surface of the flip plate 12 under the influence of gravity. The rotation of the flip plate 12 is used to complete the automatic loading of the upper and lower parts of the tank body at the same time.

[0034] At the same time, when the L-shaped plate 1441 rotates clockwise around the axis, the pressure plate 1442 also moves synchronously therewith, and the pressure plate 1442 moves from the bottom of the loading platform 141 to the top. When the L-shaped plate 1441 lifts the first can body, the pressure plate 1442 fits against the outer surface of the second can body, and can prevent the second can body from rolling downward while the flip plate 12 loads the first can body, thereby avoiding excessive loading or jamming at one time.

[0035] When the flip plate 12 rotates, the lower surface of the side plate 13 is always in contact with the bracket 17. After the flip plate 12 rotates counterclockwise to the maximum extent, the side plate 13 and the flip plate 12 are inclined at the same angle under the action of the hinge and are on the same plane. The adjacent edges of the side plate 13 and the flip plate 12 are connected with bandages, which are in a taut state at this time.

[0036] During the counterclockwise rotation of the flip plate 12, the gear 153 is sleeved on the outer surface of the rotating shaft, and the gear 153 rotates counterclockwise synchronously. The gear rod 152 on the side of the gear 153 meshes with the gear 153, and the gear rod 152 moves upward inside the base 151. The gear rod 152 drives the positioning wheel 155 to move upward through the lifting plate 154 at its top. When the can body enters the upper surface of the flip plate 12, the flip plate 12 is also in a tilted state, and the can body moves to the side plate 13 above the flip plate 12. There are two positioning wheels 155. When the can body rolls downward, its outer surface will fit with the outer surface of the positioning wheel 155 on the side close to the loading platform 141 and be stuck in this position.

[0037] The process of butt welding the tank body: The driving base runs again, driving the rotating shaft to rotate clockwise, and the flip plate 12 synchronously rotates clockwise around the central axis of the rotating shaft, and the flip plate 12 moves downward on the side close to the unloading platform 145 (the can body limited on the side of the positioning wheel 155 has a larger movable space due to the downward movement of the flip plate 12, and continues to roll on the upper side of the flip plate 12 at the side plate 13. Since the slope is small at this time and the distance between the positioning wheel 155 and the roller 16 is small, the roller flips to the roller 16 and is restricted from moving further). The lower surface of the side plate 13 contacts the top of the bracket 17. Affected by the flip plate 12, the side plate 13 is bent with the bracket 17 as the fulcrum, and the angle between the side plate 13 and the flip plate 12 gradually decreases from one hundred and eighty degrees. The side of the side plate 13 close to the unloading platform 145 is gradually in a tilted upward state.

[0038] At this time, the tilting slope of the flip plate 12 is relatively large. After the tank body passes the roller 16, it is clamped between the roller 16 and the rotating wheel 171 and is in a stable state. The flip plate 12 continues to rotate. During this process, the gear 153 on the outer surface of the rotating shaft rotates clockwise along with the rotating shaft. Accordingly, the gear rod 152 meshing with the gear 153 moves downward inside the base 151, and the positioning wheel 155 connected to the lifting plate 154 at the top of the gear rod 152 moves downward and gradually fits with the outer surface of the tank body. The rotating shaft stops rotating until the flip plate 12 rotates to the adjacent inclined surface of the side plate 13 and fits tightly. At this time, the two sets of positioning wheels 155 are in contact with the outer surface of the tank body, the central axes of the roller 16 and the rotating wheel 171 are in the same horizontal plane, and the mid-point perpendicular line of the roller 16 and the rotating wheel 171 is the same as the mid-point perpendicular line of the two positioning wheels 155. The tank body of the pressure tank can be stably clamped between the roller 16, the rotating wheel 171 and the two positioning wheels 155, avoiding the phenomenon of jumping caused by slight deviation in roundness during rotation, ensuring the stability of the welding process, and improving the welding quality.

[0039] At the same time, during the clockwise rotation of the flip plate 12, the flip plate 12 near the unloading platform 145 is in a downwardly pressed state. The linkage members 18 are symmetrically arranged with the flip plate 12 as the center. Taking one set of linkage members 18 as an example, when the bottom of the flip plate 12 rotates to connect the first connecting rod 181, the first connecting rod 181 rotates to connect the short rod 182, so that the end of the second connecting rod 183 away from the lower rack 184 moves downward, and the second connecting rod 183 drives the lower rack 184 to slide in the direction away from the first connecting rod 181 (to the right) inside the guide rail seat 185. The guide rail seat 185 is provided with a meshing rod 184. The gear ring 186 and the lower rack 184 slide to the right, driving the gear ring 186 on its upper surface to rotate counterclockwise. At the same time, the upper gear seat 187 is slidably connected to the upper surface of the guide rail seat 185 through the buckles fixed on the two sides below it. The lower middle position of the upper gear seat 187 is fixedly connected with teeth meshing with the gear ring 186. The upper gear seat 187 is affected by the gear ring 186 and slides to the left on the upper side of the guide rail seat 185 (here, the left refers to the direction close to the flip plate 12), and drives the horizontal positioning member 19 to move together.

[0040] The clockwise rotation angle of the flip plate 12 increases, and the position of the first connecting rod 181 decreases, so that the horizontal positioning member 19 moves toward the tank body to be processed inside the flip plate 12. The upper gear seat 187 is connected to the rotating disk 191 on the side close to the flip plate 12. The rotating disk 191 and the sleeve 192 move to the left together. The spring 193 inside the circumference of the sleeve 192 is initially in the expanded state, and the distance between the ball 195 at the outer end of the guide rod 194 and the rotating disk 191 is the farthest. As the flip plate 12 continues to rotate clockwise, the horizontal positioning member 19 gradually moves to the left. During this process, the outer surface of the ball 195 will contact the outer end of the curved surface of the tank body. As the horizontal positioning member 19 moves toward the middle as a whole, the guide rod 194 and the spring 193 inside the sleeve 192 begin to deform. When the elastic potential energy is greater than the thrust required to move the tank body, the horizontal positioning member 19 pushes the half tank bodies on both sides to move toward the middle until the welding surfaces of the tank bodies on both sides are aligned.

[0041] The outer circumferential surface of each half of the tank body fits the outer surfaces of the two positioning wheels 155, the roller 16, and the rotating wheel 171, and the outer ends of the tank bodies on both sides are fixed by four balls 195 through the guide rods 194. At this point, the tank body has completed the horizontal positioning and the vertical positioning.

[0042] The rotating wheel 171 rotates inside the bracket 17 through an external driving member, driving the can body to rotate, and the positioning wheel 155 and the roller 16 in contact with the outer surface of the can body also rotate accordingly, so that the can body is placed stably and the welding quality is improved.

[0043] There are notches inside the flip plate 12 and the side plate 13, and two welding head bodies 2 are provided, which are respectively arranged at the bottom of the flip plate 12 and the side plate 13. When the angle between the flip plate 12 and the side plate 13 is about 100 degrees, the welding head body 2 is inside the notch, and the welding tips of the welding head body 2 are at the left and right ends of the tank body, and the welding points are symmetrically distributed on the left and right. When the tank body rotates, the two welding head bodies 2 are welded at the same time, which helps to reduce the stress concentration of the pressure tank caused by welding.

[0044] The process of automatic unloading of pressure tanks: After welding is completed, the driving base drives the flip plate 12 to rotate counterclockwise again through the rotating shaft, and the gear rod 152 is lifted upward under the action of the gear 153, and drives the positioning wheel 155 to move upward. The side of the flip plate 12 close to the unloading platform 145 is lifted upward, and the side plate 13 is unfolded under the support of the hinge and the bracket 17 until the bandage at the connection between the side plate 13 and the flip plate 12 is in a tight state, and the angle between the side plate 13 and the flip plate 12 reaches 180 degrees. The lower surface of the side plate 13 contacts the top of the bracket 17, and the end of the side plate 13 close to the unloading platform 145 rests on the upper surface of the unloading platform 145.

[0045] When the flip plate 12 rotates counterclockwise, the flip plate 12 near the unloading platform 145 is in an upward tilted state. Taking one set of linkage parts 18 as an example, when the bottom of the flip plate 12 rotates to connect the first connecting rod 181, the first connecting rod 181 rotates to connect the short rod 182, so that the second connecting rod 183 moves upward away from the end of the lower rack 184, and the second connecting rod 183 drives the lower rack 184 to slide in the direction close to the first connecting rod 181 (to the left) inside the guide rail seat 185. The guide rail seat 185 is provided with a toothed ring 186 meshing with the lower rack 184. The lower rack 184 slides to the right and drives the toothed ring 186 on its upper surface to rotate clockwise. The upper toothed seat 187 is affected by the toothed ring 186 and slides to the right on the upper side of the guide rail seat 185 (here, the right refers to the direction away from the flip plate 12), and drives the horizontal positioning member 19 to move together.

[0046] As the counterclockwise rotation angle of the flip plate 12 increases, the position of the first connecting rod 181 rises, causing the horizontal positioning member 19 to move to the side of the tank body to be processed away from the inside of the flip plate 12. The rotating disk 191 and the sleeve 192 rotating inside the side of the upper gear seat 187 close to the flip plate 12 move to the right together, and the spring 193 inside the circumference of the sleeve 192 is expanded from the compressed state, and the distance between the ball 195 at the outer end of the guide rod 194 and the rotating disk 191 increases. As the flip plate 12 continues to rotate counterclockwise, the horizontal positioning member 19 gradually moves to the right. During this process, the outer surface of the ball 195 gradually separates from the outer end of the curved surface of the tank body. The horizontal positioning member 19 moves outward under the action of the linkage member 18, and will not interfere with the tank body after welding.

[0047] The side plate 13 is higher than the upper surface of the rotating wheel 171. The top of the welded pressure tank loses the positioning function of the positioning wheel 155, and its side loses the limit of the rotating wheel 171. Under the action of the roller 16, it moves to the lower material platform 145, successfully completing the automatic unloading action and avoiding manual handling.

[0048] In summary, in the above process, the flip plate 12 and the side plate 13 have the following advantages: Advantage 1: The flip plate 12 rotates around the central axis of the rotating shaft, and in the process, it fits with the outer surface of the connecting plate 142, driving the connecting plate 142, the L-shaped plate 1441 and the pressing plate 1442 to rotate around the shaft as a whole, and the first row of cans above the loading platform 141 are picked up and moved to the upper surface of the flip plate 12 for welding. At the same time, in this process, the pressing plate 1442 blocks the cans in the next position, avoiding the phenomenon of multiple cans being unloaded and stuck at the same time. When the flip plate 12 is removed, the loading piece 144 returns to its initial state under the action of the torsion spring 143, and the next can is replaced and waits for the next welding. It avoids manual handling of cans for loading, which can effectively improve production efficiency.

[0049] Advantage 2: The flip plate 12 is rotatably connected to the side plate 13 through a hinge. When the flip plate 12 rotates counterclockwise and the angle between the flip plate 12 and the side plate 13 is 180 degrees, the side plate 13 and the flip plate 12 are in the same plane with the same slope. At this time, the positioning wheel 155 moves up, and the highest point of the rotating wheel 171 is lower than the bottom of the side plate 13. The welded tank body can naturally complete the unloading action under the action of gravity, avoiding the situation where manual labor is injured due to carrying the pressure tank that has just been welded, and continuous loading and unloading can be achieved through the flip plate 12 for welding.

[0050] Advantage three: there are two welding head bodies 2, which are respectively located on the left and right sides of the pressure tank body. When the tank body is rotated by the rotating wheel 171, the two welding head bodies 2 weld the pressure tank at the same time. When the pressure tank rotates 180 degrees, one layer of welding can be completed, which helps to reduce stress concentration caused by pressure imbalance.

[0051] Advantage 4: When the rotating shaft drives the flip plate 12 to rotate counterclockwise, the gear rod 152 meshing with the gear 153 moves upward inside the base 151, driving the positioning wheel 155 to move upward, which helps the pressure tank to be unloaded smoothly after welding; when the rotating shaft drives the flip plate 12 to rotate clockwise, the gear rod 152 meshing with the gear 153 moves downward inside the base 151, driving the positioning wheel 155 to move downward, which can ensure the stability of the tank body during welding, ensure the stability during rotation, and improve the welding quality. Since the median perpendicular of the upper positioning wheel 155, the lower rotating wheel 171 and the roller 16 are the same, the tank body is uniformly constrained and supported in the circumferential direction, avoiding the deformation of the tank body caused by excessive local force. The lower rotating wheel 171 and the roller 16 mainly bear the weight of the tank body and provide upward support force, and the two upper positioning wheels 155 assist in fixing the tank body through downward pressure. This symmetrical layout makes the combined force on the tank body evenly distributed in the circumferential direction, avoiding tilting, shaking, etc. caused by uneven force.

[0052] Advantage 5. When the flip plate 12 rotates clockwise around the central axis of the rotating shaft, the lower rack 184 is driven to move outward by the first connecting rod 181. Under the action of the gear ring 186, the upper gear seat 187 and the horizontal positioning member 19 move toward the middle (toward the direction of the can body to be processed). The horizontal positioning member 19 is used to complete the centering action of the can bodies on both sides, ensuring stability during the processing.

[0053] Advantage six: The minimum angle range between the side plate 13 and the flip plate 12 is constant. When the angle is minimum, the roller 16 and the rotating wheel 171 are in the same horizontal plane (the diameters of the roller 16 and the rotating wheel 171 are the same), and the two positioning wheels 155 in the same group at the top are also in the same horizontal plane, and the mid-vertical line between the two positioning wheels 155 and the mid-vertical line between the roller 16 and the rotating wheel 171 are the same, which can adapt to butt welding of tanks of different diameters within a certain range, and has a wide applicability.

[0054] Advantage seven, the spring 193 in the horizontal positioning member 19 can play the role of buffering and shock absorption, and absorbs these impact forces through its own elastic deformation, making the pressing process smoother. When the diameter of the tank body changes, when the central axis of the tank body and the central axis of the rotating disk 191 are offset, the four separately arranged sleeves 192, springs 193, guide rods 194 and balls 195 can adapt to the different protruding distances of the arc surface end of the tank body and adapt to positioning at different parts. When the horizontal positioning member 19 contacts a tank body with an irregular shape or a slightly changed size, the spring 193 will expand and contract accordingly, so that the horizontal positioning member 19 always maintains good contact with the surface of the tank body.

[0055] Advantage 8: When the horizontal positioning member 19 moves too far and contacts the outer end of the tank too closely, the rotating disk 191 inside the upper gear seat 187 can rotate with the tank to adapt to different clamping forces, thus avoiding the phenomenon that the tank cannot rotate at a normal speed due to excessive clamping force in the horizontal direction.
