[0047] 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 .

[0048] The process of automatic tank loading:

[0049] In practical applications, before welding, the pressure tank is divided into two symmetrical tank bodies, the upper and the lower. In the middle above the loading table 141, there is a partition plate 1411 which divides the loading table 141 into two parts on the left and right, where the upper and lower tank bodies of the pressure tank are respectively placed. The tank bodies are neatly arranged. There are also two connecting plates 142 which are symmetrically designed left and right with the partition plate 1411 as the center. On both sides of the loading table 141, there are side baffles for restricting the position of the tank bodies. The tank bodies are neatly stacked between the side baffles and the partition plate 1411. The top plane of the loading table 141 is designed in an inclined manner, with the side closer to the turning plate 12 being lower. Under the action of natural gravity, the tank bodies will roll towards the turning plate 12. On the side of the loading table 141 closer to the turning plate 12, there is a connecting plate 142. The inside of the connecting plate 142 is connected to a shaft rod through a torsion spring 143. Both ends of the shaft rod penetrate through the inside of the partition plate 1411 and the side baffles respectively.

[0050] In the initial state, the connecting plate 142 is in an upward inclined state. The connecting plate 142, the L-shaped plate 1441 and the pressing plate 1442 are integrally formed. The included 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 far from the connecting plate 142 is on the same plane as the upper surface of the loading table 141, while the pressing plate 1442 is hidden at the bottom of the loading table 141. All the loading parts 144 are inside the through grooves of the loading table 141. For the first two tank bodies on the upper surface of the loading table 141 close to the turning plate 12, the bottom ends and the side vertices are in contact with the outer surfaces of the two L-shaped plates 1441 on both sides.

[0051] In the initial state, the turning plate 12 is in an inclined state. The included angle between the turning plate 12 and the side plate 13 is about 100 degrees. The lower surface of the side plate 13 is in contact with the hypotenuse of the bracket 17 to play a supporting role. The adjacent sides of the side plate 13 and the turning plate 12 are both designed as hypotenuses. At this time, the hypotenuses of the side plate 13 and the turning plate 12 are completely in contact. The turning plate 12 is under the supporting action of the bracket 17 on the side plate 13 and is also in a relatively fixed state. At this time, the roller 16 and the central axis of the rotating wheel 171 are on the same horizontal plane (the roller 16 and the rotating wheel 171 have the same size and radius). The roller 16 is fixedly connected to the lower surface of the turning plate 12 through a connecting frame and always moves with the turning plate 12. The toothed rod 152 is inside the base 151, and the lifting plate 154 at the bottom end of the toothed rod 152 is at the lowest point at this time.

[0052] The rotating shaft inside the support frame 11 is connected through a driving base. After the driving base starts, it drives the rotating shaft to rotate counterclockwise. At the same time, the turning plate 12 fixedly connected to the rotating shaft rotates counterclockwise synchronously. The side of the turning plate 12 close to the loading table 141 starts to press down. During this process, the bottom surface of the outer end of the turning plate 12 will contact the outer surface of the connecting plate 142. As the turning plate 12 rotates counterclockwise by an increasing angle, the degree to which the connecting plate 142 is pressed down 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 and the pressing plate 1442 are integrally designed with the connecting plate 142, the L-shaped plate 1441 will rotate clockwise around the shaft rod along with it.

[0053] The L-shaped plate 1441 moves upward from inside the through slot and drives the previous can body close to the turning plate 12 to tilt. The center of gravity of the can body initially in contact with the outer surface of the L-shaped plate 1441 is above the loading table 141; when the L-shaped plate 1441 starts to rotate, as the L-shaped plate 1441 rises above the upper surface of the loading table 141, the center of gravity of the can body is on the bottom plate of the L-shaped plate 1441 far from the connecting plate 142; the L-shaped plate 1441 continues to rotate into a "V" shape with the opening facing upward, and the can body is clamped inside the L-shaped plate 1441. Until the turning plate 12 rotates to the designated position, the bottom plate of the L-shaped plate 1441 far from the connecting plate 142 is perpendicular to the loading table 141, and the center of gravity of the can body is above the top plate of the L-shaped plate 1441 close to the connecting plate 142, and the top plate of this L-shaped plate 1441 is in an inclined state, with the side close to the turning plate 12 being lower. The can body moves toward the upper surface of the turning plate 12 under the influence of gravity. The rotation of the turning plate 12 is used to complete the simultaneous automatic loading action of the upper and lower divided can bodies.

[0054] At the same time, when the L-shaped plate 1441 rotates clockwise around the shaft rod, the pressing plate 1442 also moves synchronously. The pressing plate 1442 moves from its initial position below the loading table 141 to above it. When the L-shaped plate 1441 tilts the first can body, the pressing plate 1442 fits against the outer surface of the second can body, and can resist the second can body from rolling down while the turning plate 12 loads the first can body, avoiding the situation of excessive or jammed loading at one time.

[0055] When the turning plate 12 rotates, the lower surface of the side plate 13 always contacts the bracket 17. After the turning plate 12 rotates counterclockwise to the maximum extent, the side plate 13 and the turning plate 12 have the same inclination angle under the action of the hinge and are on the same plane. A bandage is connected to the adjacent side of the side plate 13 and the turning plate 12, and at this time the bandage is in a taut state.

[0056] During the counterclockwise rotation of the turning plate 12, the gear 153 is sleeved on the outer surface of the rotating shaft, and the gear 153 rotates counterclockwise synchronously. The rack 152 on the side of the gear 153 meshes with the gear 153, and the rack 152 moves upward inside the base 151. The rack 152 drives the positioning wheel 155 to move upward together through the lifting plate 154 at its top end. When the tank body enters the upper surface of the turning plate 12, the turning plate 12 is also in an inclined state, and the tank body moves toward the side plate 13 above the turning plate 12. There are two positioning wheels 155. When the tank body rolls downward, the outer surface of the tank body will be in contact with the outer surface of the positioning wheel 155 close to the feeding table 141 and be clamped at this position.

[0057] Process of butt welding the tank body:

[0058] The driving base runs again, driving the rotating shaft to rotate clockwise. The turning plate 12 synchronously rotates clockwise with the central axis of the rotating shaft as the axis. The side of the turning plate 12 close to the discharging table 145 moves downward (the tank body limited on the side of the positioning wheel 155 can move more freely due to the downward movement of the turning plate 12 and continues to roll toward the side plate 13 above the turning plate 12. Since the slope is small at this time and the distance between the positioning wheel 155 and the roller 16 is small, the drum is flipped to the roller 16 and is restricted from moving further). The lower surface of the side plate 13 contacts the top end of the bracket 17. Affected by the turning plate 12, the side plate 13 bends with the bracket 17 as the fulcrum. The angle between the side plate 13 and the turning plate 12 gradually decreases from 180 degrees, and the side of the side plate 13 close to the discharging table 145 gradually tilts upward.

[0059] At this time, the inclination slope of the turning plate 12 is large. After the tank body passes through the roller 16, it is clamped between the roller 16 and the rotating wheel 171 and is in a stable state. The turning plate 12 continues to rotate. During this process, the gear 153 sleeved on the outer surface of the rotating shaft rotates clockwise simultaneously with the rotating shaft. Correspondingly, the rack 152 meshing with the gear 153 moves downward inside the base 151. The positioning wheel 155 connected to the top end of the rack 152 by the lifting plate 154 moves downward and gradually contacts the outer surface of the tank body. Until the turning plate 12 rotates to be closely attached to the adjacent inclined surface of the side plate 13, the rotating shaft stops rotating. At this time, both groups 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 on the same horizontal plane, and the perpendicular bisector of the roller 16 and the rotating wheel 171 is the same as the perpendicular bisector of the two positioning wheels 155, which can stably clamp the tank body of the pressure tank between the roller 16, the rotating wheel 171, and the two positioning wheels 155, avoiding the phenomenon of jumping caused by slightly deviated roundness during rotation, ensuring the stability of the welding process, and improving the welding quality.

[0060] Meanwhile, during the clockwise rotation of the turning plate 12, the turning plate 12 on the side close to the blanking table 145 is in a downward pressing state. There are two sets of linkage members 18 symmetrically arranged with the turning plate 12 as the center. Taking one set of linkage members 18 as an example, when the first connecting rod 181 is rotatably connected below the turning plate 12, the first connecting rod 181 is rotatably connected to the short rod 182, so that one end of the second connecting rod 183 far from the lower rack 184 moves downward. The second connecting rod 183 drives the lower rack 184 to slide inside the guide rail seat 185 in a direction away from the first connecting rod 181 (to the right). A toothed ring 186 meshing with the lower rack 184 is arranged inside the guide rail seat 185. The rightward sliding of the lower rack 184 drives the toothed ring 186 on its upper surface to rotate counterclockwise. At the same time, the upper tooth seat 187 is slidably connected to the upper surface of the guide rail seat 185 through buckles fixed on both sides below it. A tooth engaging with the toothed ring 186 is fixedly connected to the middle position below the upper tooth seat 187. Affected by the toothed ring 186, the upper tooth seat 187 slides leftward on the upper surface of the guide rail seat 185 (here, leftward refers to the direction close to the turning plate 12), and drives the horizontal positioning member 19 to move together.

[0061] As the clockwise rotation angle of the turning plate 12 increases, the position of the first connecting rod 181 decreases, so that the horizontal positioning member 19 moves towards the tank body to be processed inside the turning plate 12. A rotating disc 191 is rotatably connected to the inside of the side of the upper tooth seat 187 close to the turning plate 12. The rotating disc 191 and the sleeve 192 move leftward together. The spring 193 inside the circumference of the sleeve 192 is initially in an unfolded state. The distance between the ball 195 at the outer end of the guide rod 194 and the rotating disc 191 is the farthest. As the turning plate 12 continues to rotate clockwise, the horizontal positioning member 19 gradually moves leftward. During this process, the outer surface of the ball 195 will contact the outer arc surface of the tank body. As the horizontal positioning member 19 moves towards the middle as a whole, the guide rod 194 and the spring 193 inside the sleeve 192 start to deform. When the elastic potential energy is greater than the thrust required to move the tank body, the horizontal positioning member 19 respectively pushes the two half tank bodies on both sides towards the middle until the welding surfaces of the tank bodies on both sides are aligned.

[0062] The outer circumferential surface of each half tank body fits with the outer surfaces of the two positioning wheels 155, the rollers 16, and the rotating wheels 171. The outer ends of the tank bodies on both sides are fixed by four balls 195 through the guide rods 194. Thus, the horizontal positioning of the tank body is completed and the vertical positioning is also completed.

[0063] The rotating wheel 171 rotates inside the bracket 17 through an external driving member, driving the tank body to rotate. The positioning wheels 155 and the rollers 16 in contact with the outer surface of the tank body also rotate accordingly, so that the tank body is stably placed, improving the welding quality.

[0064] There are notches inside both the turning plate 12 and the side plate 13. There are two welding head bodies 2, which are respectively arranged at the bottoms of the turning plate 12 and the side plate 13. When the angle between the turning plate 12 and the side plate 13 is about one hundred degrees, the welding head bodies 2 are inside the notches, and the welding tips of the welding head bodies 2 are at the left and right ends of the tank body. The welding points are symmetrically distributed left and right. When the tank body rotates, the two welding head bodies 2 weld simultaneously, which helps to reduce the stress concentration caused by welding of the pressure tank.

[0065] The process of automatically discharging the pressure tank:

[0066] After welding is completed, the driving base drives the turning plate 12 to rotate counterclockwise again through the rotating shaft. The toothed 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 turning plate 12 close to the blanking table 145 is lifted upward. 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 turning plate 12 is in a taut state, and the angle between the side plate 13 and the turning plate 12 reaches one hundred and eighty degrees. The lower surface of the side plate 13 contacts the top end of the bracket 17, and one end of the side plate 13 close to the blanking table 145 rests on the upper surface of the blanking table 145.

[0067] When the turning plate 12 rotates counterclockwise, the turning plate 12 on the side close to the blanking table 145 is in an upwardly tilted state. Taking one set of linkage members 18 as an example, when the first connecting rod 181 is rotatably connected below the turning plate 12, the first connecting rod 181 is rotatably connected to the short rod 182, so that one end of the second connecting rod 183 far from the lower toothed rack 184 moves upward. The second connecting rod 183 drives the lower toothed rack 184 to slide inside the guide rail seat 185 in the direction close to the first connecting rod 181 (to the left). A toothed ring 186 meshing with the lower toothed rack 184 is arranged inside the guide rail seat 185. The rightward sliding of the lower toothed rack 184 drives the toothed ring 186 on its upper surface to rotate clockwise. The upper toothed seat 187 slides to the right above the guide rail seat 185 under the influence of the toothed ring 186 (here, to the right means the direction away from the turning plate 12) and drives the horizontal positioning member 19 to move together.

[0068] As the angle of counterclockwise rotation of the turning plate 12 increases, the position of the first connecting rod 181 rises, causing the horizontal positioning member 19 to move away from the side of the tank body to be processed inside the turning plate 12. The rotating disk 191 and the sleeve 192 that rotate inside the side of the upper tooth seat 187 close to the turning plate 12 move to the right together. The spring 193 inside the circumference of the sleeve 192 unfolds 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 turning 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 disengages from the outer end of the arc 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 welded tank body.

[0069] The side plate 13 is higher than the upper surface of the rotating wheel 171. The top end of the pressure tank after welding 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 towards the blanking table 145, successfully completing the automatic blanking action and avoiding manual handling.

[0070] In summary, during the above process, the turning plate 12 and the side plate 13 have the following advantages:

[0071] Advantage 1: By rotating the turning plate 12 around the central axis of the rotating shaft, during this 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 rod as a whole, picking up the first row of tank bodies above the loading table 141 and moving them to the upper surface of the turning plate 12 to prepare for welding. At the same time, during this process, the pressing plate 1442 blocks the subsequent tank body, avoiding the phenomenon of multiple tank bodies being blanked and stuck at the same time. When the turning plate 12 is removed, the loading member 144 returns to its initial state under the action of the torsion spring 143, and the next tank body replaces it and waits for the next welding. It avoids manual handling of the tank body for loading and can effectively improve production efficiency.

[0072] Advantage 2: The turning plate 12 is rotatably connected to the side plate 13 through a hinge. When the turning plate 12 rotates counterclockwise and the included angle between the turning plate 12 and the side plate 13 is 180 degrees, the side plate 13 and the turning plate 12 are in the same plane with the same slope. At this time, the positioning wheel 155 moves upward, and the highest point of the rotating wheel 171 is lower than the lower side of the side plate 13. The welded tank body can naturally complete the blanking action under the action of gravity, avoiding the situation of manual injury caused by handling the just-welded pressure tank. It can realize continuous loading and unloading through the turning plate 12 for welding.

[0073] Advantage 3: 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 driven to rotate by the rotating wheel 171, the two welding head bodies 2 weld the pressure tank simultaneously. When the pressure tank rotates 180 degrees, one layer of welding can be completed, which helps to reduce the stress concentration caused by unbalanced pressure.

[0074] Advantage 4: When the rotating shaft drives the turning plate 12 to rotate counterclockwise, the rack bar 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 after welding to be discharged smoothly; when the rotating shaft drives the turning plate 12 to rotate clockwise, the rack bar 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 the welding process, ensure the stability during rotation, and improve the welding quality. Since the vertical bisectors 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 stress. The lower rotating wheel 171 and the roller 16 mainly bear the weight of the tank body and provide an upward supporting force, while the two upper positioning wheels 155 assist in fixing the tank body through a downward pressure. This symmetric layout makes the resultant force on the tank body evenly distributed in the circumferential direction, avoiding tilting, shaking and other situations caused by uneven stress.

[0075] Advantage 5: When the turning plate 12 rotates clockwise around the central axis of the rotating shaft, the lower rack bar 184 is driven to move outward by the first connecting rod 181. Under the action of the toothed ring 186, the upper tooth seat 187 and the horizontal positioning member 19 move towards the middle (move towards the tank body to be processed), and the centering action of the two side tank bodies is completed by using the horizontal positioning member 19, ensuring the stability during the processing.

[0076] Advantage 6: The minimum included angle range between the side plate 13 and the turning plate 12 is constant. When the included angle is the smallest, the roller 16 and the rotating wheel 171 are on 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 on the same horizontal plane, and the vertical bisectors between the two positioning wheels 155, the roller 16 and the rotating wheel 171 are the same, which can adapt to the butt welding of tanks with different diameters within a certain range, and has a wide applicability.

[0077] Advantage 7: The spring 193 in the horizontal positioning member 19 can function as a buffer and shock absorber, absorbing these impact forces through its own elastic deformation to make the pressing process smoother. When the diameter of the tank body changes and the central axis of the tank body deviates from the central axis of the rotating disk 191, the four respectively provided sleeves 192, springs 193, guide rods 194 and balls 195 can adapt to different protruding distances of the arc end of the tank body and adapt to different positions for positioning. When the horizontal positioning member 19 contacts a tank body with an irregular shape or 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.

[0078] Advantage 8: When the moving distance of the horizontal positioning member 19 is too large and it contacts the outer end of the tank body too tightly, the rotating disk 191 inside the upper tooth seat 187 can rotate following the tank body to adapt to different clamping forces, avoiding the phenomenon that the tank body cannot rotate at a normal speed due to excessive clamping force in the horizontal direction.
