[0002] During container production, a mold is first used to create the blank. After demolding, the wet blank is transported to the next process. Handling wet container blanks, especially large ones, is impossible due to their weight and size.

[0003] Currently, crane hoists are commonly used to lift wet billets and transfer them to overhead cranes for transport. However, lifting wet billets with crane hoists requires first setting up a gantry crane, then manually operating the crane hoist and manually participating in the transfer of the wet billets. This method has a low degree of automation, carries operational risks during movement, and affects production efficiency.

[0004] Meanwhile, forklifts are also used to move and transfer wet billets. Forklift operation typically requires sufficient operating space for maneuvering, turning, and loading / unloading wet billets, while also needing to consider safety distances to prevent collisions and accidents. Therefore, providing sufficient operating space for forklifts results in low space utilization within the factory.

[0042] Please refer to the accompanying drawings Figures 1-4 A carrying assembly is arranged on the lifting seat 4, the carrying assembly comprises two arm embracing groups, the two arm embracing groups are distributed on the lifting seat 4 in an up-down mode, each arm embracing group is composed of two arc-shaped arm embracing parts which are crossly rotatably connected, the arm embracing groups are arranged on the lifting seat 4 by means of scissor supports 7, the lifting seat 4 can provide assembly positions for the scissor supports 7 by assembling supports, hinge shafts of the scissor supports 7 are fixedly installed on the supports, so that the scissor supports 7 make scissor movements around the hinge shafts, in order to simplify the structure, the hinge shafts can be fixedly assembled with the supports, two ends of the hinge shafts are rotatably connected with the scissor supports 7 distributed in an up-down mode respectively, assembly strength is ensured, the scissor supports 7 further comprise two force arms 701 which are scissor-connected, one end of each force arm 701 is fixedly connected with the arm embracing part 5, in order to ensure the connection strength of the two, the force arm 701 is matched with the arm embracing part 5 in shape, so that the assembly area is increased, the arm embracing part 5 can be fixedly held in an up-down mode by increasing the number of the force arms 701, and assembly reliability is further ensured, free ends of the two force arms 701 are driven to open and close by an opening and closing driving mechanism;

[0043] Please refer to the accompanying drawings Figures 1-4When the opening and closing drive mechanism drives the scissor arm 5 to open and close via the scissor bracket 7, the scissor bracket 7 can be linked together with the linkage component to drive the two scissor arm groups to run synchronously. The linkage component includes a connecting shaft 8 set between the two scissor arm groups. The connecting shaft 8 is set in parallel, and both ends of the connecting shaft 8 are respectively rotatably hinged to the free ends of the lever arm 701. When the opening and closing drive mechanism drives the two connecting shafts 8 to move closer or further away from each other, it drives the two lever arms 701 on the scissor bracket 7 to perform scissor movements, so that the scissor arm 5 opens and closes. Its structure is simple, reduces the failure rate, extends the service life, and ensures the reliability of use.

[0044] Please see the appendix Figures 1-4 The opening and closing drive mechanism can be an opening and closing telescopic cylinder 9. The opening and closing telescopic cylinder 9 is fixedly connected to one of the connecting shafts 8, and the output end of the opening and closing telescopic cylinder 9 passes through the connecting shaft 8 and is fixedly connected to the other connecting shaft 8. When the opening and closing telescopic cylinder 9 is running, it drives the two connecting shafts 8 to approach or separate from each other, so that the two lever arms 701 on the drive scissor bracket 7 perform scissor movement, and the arm 5 opens and closes.

[0045] When the clamping arms 5 open and close, a cloth strap is installed between the two clamping arm assemblies. The upper and lower ends of the left and right parts of the cloth strap are fixedly connected to the two clamping arms 5 distributed vertically. Each clamping arm 5 located above the upper clamping arm 5 has a connecting frame 501 on its top surface. The connecting frame 501 corresponds to the shape of the clamping arm 5. The top of the cloth strap is suspended on the connecting frame 501. The cloth strap is suspended from the connecting frame 501 at multiple points to ensure reliable connection. The bottom of the cloth strap hangs freely on the lower clamping arm 5 and can be tied to the clamping arm 5 with ropes. The multi-point suspension connection between the fabric belt and the connecting frame 501 ensures the flatness of the fabric belt. When handling the wet blank, the clamping arm 5 closes to cover the outside of the wet blank with the fabric belt. As the lifting seat 4 moves upward along the rotating frame 3, the clamping arm 5 moves the fabric belt upward. Since the container (cylinder or jar) is generally a structure that is thicker at the top and thinner at the bottom (generally not a straight cylindrical structure), after the fabric belt is closed, the outer wall of the container's wet blank contacts the inner wall of the fabric belt, and the wet blank is stuck on the fabric belt, thus allowing the fabric belt to lift the wet blank. (Appendix) Figure 2 The diagram shows the structure of the cloth belt transporting the wet blank. The cloth belt is hidden to show the position of the wet blank. Based on the above, it can be concluded that the cloth belt located between the two sets of 5 clamps contacts and adheres to the larger diameter part of the wet blank, thereby lifting the wet blank. Then the sliding seat 2 transfers the wet blank to the end of the horizontal base frame 1 and rotates along the horizontal base frame 1 to transfer the wet blank to the production line for other processing. Example 2

[0046] Please see the appendix Figure 5 Appendix Figure 6The carrying assembly on the lifting seat 4 can also be provided with two straight arm clamps 6 on the lifting seat 4, which are respectively arranged on the two sides of the lifting seat 4 in the length direction and are slidingly arranged with the lifting seat 4. The lifting seat 4 is additionally provided with a sliding rail, and a sliding block is arranged on the sliding rail in a matched manner. The sliding block is fixedly installed with the two straight arm clamps 6, respectively. The two straight arm clamps 6 are driven to relatively reciprocate along the lifting seat 4 by means of the linear driving assembly, so as to approach or separate from each other. The straight arm clamps 6 move along the lifting seat 4 by means of the matched sliding rail and sliding block, thereby reducing the driving load of the linear driving assembly, and the sliding of the two supporting arms is smooth and stable.

[0047] The inner bottom of the straight arm clamp 6 is fixedly installed with an arc-shaped supporting plate 601. The linear driving assembly drives the two supporting arms to move in an opening and closing mode. The linear driving assembly is a linear telescopic cylinder 10. The linear telescopic cylinder 10 is arranged on the two straight arm clamps 6, respectively. The cylinder body of the linear telescopic cylinder 10 is fixedly installed with the straight arm clamps 6, respectively. The output end of the linear telescopic cylinder 10 penetrates the straight arm clamps 6, respectively, and is fixedly installed with the assembly panel 11 on the lifting seat 4. When the linear telescopic cylinder 10 is in telescopic operation, the straight arm clamps 6 drive the supporting plate 601 to synchronously approach or separate, so as to realize the opening and closing of the supporting plate 601. The operation is stable. When the wet blank is carried, the supporting plate 601 is closed below the supporting tray supporting the wet blank. After the lifting seat 4 is moved upward along the rotating stand 3, the supporting tray is lifted upward, the wet blank is lifted together, and is transferred along the horizontal chassis 1. The operation is simple and flexible. After the supporting tray lifts the wet blank, the sliding seat 2 transfers the wet blank to the end of the horizontal chassis 1 and rotates along the horizontal chassis 1. The wet blank is transferred to the production line and is processed by other processes.

[0048] The working principle of the pot or cylinder production wet base carrying device is as follows: when the arc-shaped arm 5 is used to carry the wet base, the force arm 701 is initially in an open state, the arm 5 is unfolded, and is located on one side of the wet base. When carrying it, the opening and closing telescopic cylinder 9 operates, drives the connecting shaft 8 to move close to each other, so that the force arm 701 makes a scissors movement along the center axis, and drives the arm 5 to close, so that it forms a ring structure around the wet base, and the cloth tape on the arm 5 covers the outside of the wet base. Then the lifting seat 4 moves upward along the rotating stand 3, the sliding rail on the rotating stand 3 and the sliding block on the lifting seat 4 ensure the smoothness of lifting and sliding, and reduce the driving load. When the lifting seat 4 drives the arm 5 to move upward, the cloth tape contacts the wet base to apply a supporting force to the wet base. With the continuous upward movement of the lifting seat 4, the wet base is lifted. The wet base is in the cloth tape, and the flexible contact between the wet base and the cloth tape avoids damage to the wet base. After the wet base is lifted to a certain height, the sliding seat 2 moves along the horizontal chassis 1, and the sliding rail on the horizontal chassis 1 and the sliding block on the sliding seat 2 also ensure the smoothness of sliding and reduce the driving load. When the straight arm arm supporting plate is used to carry the wet base, the straight arm arm 6 is initially in a separated state, and the supporting plate 601 at the bottom of the straight arm arm 6 is lowered to the side of the supporting plate of the wet base. The linear telescopic cylinder 10 drives the straight arm arm 6 to move close to each other, so that the supporting plate 601 is closed and located below the supporting plate. Then the lifting seat 4 moves upward along the rotating stand 3, so that the supporting plate 601 contacts the supporting plate and lifts the supporting plate upward to a certain height, and then the sliding seat 2 moves along the horizontal chassis 1. After the wet base is transferred to the other side of the horizontal chassis 1, the rotating stand 3 rotates along the sliding seat 2, and the wet base is transferred to the next process. Then the rotating stand 3, the sliding seat 2 and the lifting seat 4 are reset to continue carrying the wet base, ensure the smoothness of wet base carrying and transferring, and reduce the operation difficulty, ensure the safety.
