[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 to Figure 4In the embodiment of the utility model, a protective structure for canning large barrels of butyl rubber includes a connecting seat 1 for supporting the barrel, and a synchronous rotation mechanism is connected to one side of the vertical plate of the connecting seat 1. The synchronous rotation mechanism is used to protect the outer periphery of the barrel to prevent the barrel from tipping over;

[0023] The synchronous rotation mechanism comprises two symmetrically arranged protection rings 3, and a limiting mechanism is distributed inside one protection ring 3 and at the top of the horizontal plate portion of the connecting seat 1;

[0024] The limiting mechanism is used to limit the two protective rings 3 in the closed state to prevent the two protective rings 3 from actively rotating and opening.

[0025] In this embodiment: when the empty containing barrel is placed on the horizontal plate part of the connecting seat 1, the two protective rings 3 are in an open state. After the placement is completed, a force is applied to one protective ring 3 to close the protective ring 3, and the protective ring 3 drives the other protective ring 3 to close synchronously through the synchronous rotation mechanism. After the closing process, the limiting mechanism limits the current state of the two protective rings 3 to avoid the problem of the protective rings 3 opening by themselves when the connecting seat 1 moves upward, thereby achieving the purpose of protecting the empty containing barrel.

[0026] Please refer to Figure 1 and Figure 3 The synchronous rotation mechanism includes a rotating seat 2 fixedly mounted on one side of the vertical plate portion of the connecting seat 1, a protective ring 3 rotatably connected between the upper and lower rotating seats 2, the protective ring 3 and the rotating seat 2 are rotatably connected through a rotating shaft, the rotating shaft is fixedly connected to the protective ring 3, and the outer periphery of the rotating shaft is located above the protective ring 3 and is interference-fitted with a gear 7, and the two gears 7 are meshed.

[0027] In this embodiment: when closing the two protective rings 3, force is applied to one protective ring 3, and the protective ring 3 is rotated with the rotating shaft as the center. At the same time, the rotating shaft drives the gear 7 to rotate synchronously, and the gear 7 drives another gear 7 to rotate synchronously. The two gears 7 rotate in opposite directions, so the two protective rings 3 rotate synchronously in opposite directions until they are completely closed. During the closing process, the two protective rings 3 position and correct the containing barrel so that the containing barrel is located directly below the filling port of the filling machine equipment. At the same time, the containing barrel is protected to avoid the risk of the empty containing barrel falling during the lifting process.

[0028] Please refer to Figure 2 , Figure 3 and Figure 4 The limiting mechanism includes a limiting rod 5 and a limiting block 6. The limiting rod 5 is fixedly connected to the top of the horizontal plate portion of the connecting seat 1. A sliding groove 13 is vertically opened inside a protective ring 3. A spring 14 is fixedly connected to one end of the inner wall of the sliding groove 13, and the other end of the spring 14 is connected to the limiting block 6.

[0029] In this embodiment: during the rotation and closing process of the protective ring 3, one protective ring 3 drives the limit block 6 to move synchronously. When the two protective rings 3 are about to close, the arc surface of the limit block 6 contacts and squeezes the outer periphery of the limit rod 5, and the limit block 6 moves along the slide groove 13 under the force, and the spring 14 is squeezed at this time. When the two protective rings 3 are rotated and closed, the limit block 6 and the limit rod 5 are misaligned, and the spring 14 is reset to push the limit block 6 to fit tightly against the surface of the limit rod 5. At this time, the protective ring 3 is subjected to the limiting force, and the protective ring 3 cannot rotate open by itself, and the other protective ring 3 cannot rotate open by itself, thereby protecting the empty barrel and preventing it from deflecting or falling during the rising process.

[0030] Please refer to Figure 4 One end of the limit block 6 located outside the protective ring 3 has an arc surface structure, and the other end of the limit block 6 located inside the slide groove 13 has a "convex" cross-section structure.

[0031] In this embodiment: when the limit block 6 contacts the limit rod 5, the arc surface is squeezed by force, so that the limit block 6 can move along the slide groove 13, and the other end of the limit block 6 is a "convex" structure, which can avoid the limit block 6 and the slide groove 13 from separating.

[0032] Please refer to Figure 1 A handle 4 is fixedly mounted on the top of a protective ring 3 with a limiting mechanism inside.

[0033] In this embodiment: after the drum is filled and dropped to the lowest position, the handle 4 is pulled to drive the protective ring 3 connected thereto to open, and the protective ring 3 drives the two protective rings 3 to open synchronously through the synchronous rotation mechanism.

[0034] Please refer to the figure carefully. Three moving seats 10 are installed at the back end of the vertical plate part of the connecting seat 1. The inner wall of the moving seat 10 in the middle is threadedly connected with a screw 8, and the inner walls of the moving seats 10 on both sides are slidably connected with sliding columns 9. The bottom of the screw 8 is equipped with a worm gear 11, and the outer periphery of the worm gear 11 is meshed with a worm 12.

[0035] In this embodiment: after the two protective rings 3 rotate, the motor connected to the worm 12 is started, the motor drives the worm 12 to rotate, the worm 12 drives the worm wheel 11 to rotate, thereby driving the screw 8 to rotate, and due to the limitation of the connecting seat 1 sliding column 9, the driving screw 8 drives the connecting seat 1 to move up and down.

[0036] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
