Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] Please refer to Figures 1-5 , the packaging machine round body opening and closing structure in the figure, including workbench 101, workbench 101 is rotatably connected with rotating disc 102, the side close to rotating disc 102 of workbench 101 is fixedly connected with first L-shaped plate 103 and second L-shaped plate 104, the side away from workbench 101 of first L-shaped plate 103 is wound with packaging bag 106 through mounting frame 105, still including the limiting assembly for limiting during the packaging process of circular object arranged on workbench 101;

[0024] The limiting assembly includes two mutually symmetrical fixed plates 201 fixedly connected to the side away from workbench 101 of rotating disc 102, the opposite side of two fixed plates 201 is provided with a plurality of arc-shaped limiting plates 202 arranged in pairs and mutually symmetrical, the side close to circular object of each arc-shaped limiting plate 202 is rotatably connected with a plurality of rotating balls 203, two fixed plates 201 are provided with telescopic assembly for telescoping arc-shaped limiting plate 202;

[0025] It needs to be explained here that: through the setting of limiting assembly, while ensuring the completeness of the wrapping of packaging bag 106 on the surface of circular object, effective limiting during the packaging process of circular object is realized, so that the risk of position deviation of circular object in the packaging process is reduced, and the quality of packaging of circular object is further improved.

[0026] It is worth noting that: the limiting assembly is provided with a plurality of limiting assemblies, and each limiting assembly is arranged in an annular array.

[0027] Please refer to Figure 3The side of each arc-shaped limiting plate 202 in the drawing is fixedly connected with an inclined plate 204;

[0028] It should be noted here that the inclined plate 204 provides a guiding effect for the placement and taking of the circular object.

[0029] Please refer to Figure 3 The telescopic assembly in the drawing includes a telescopic pipe 301 fixedly connected to the fixed plate 201 near one side of the arc-shaped limiting plate 202, the telescopic pipe 301 is slidingly connected with a telescopic rod 302, one end of the telescopic rod 302 is connected with the arc-shaped limiting plate 202, the other end of the telescopic rod 302 is located in the telescopic pipe 301 and is fixedly connected with a telescopic plate 303, the side of the telescopic plate 303 away from the telescopic rod 302 is fixedly connected with a spring 304, the other end of the spring 304 is connected with the bottom wall of the telescopic pipe 301, and the telescopic pipe 301 is provided with a guide assembly for guiding the movement of the telescopic plate 303.

[0030] It should be noted here that the telescopic assembly provides a telescopic variable for the movement of the arc-shaped limiting plate 202.

[0031] Please refer to Figure 3 The guide assembly in the drawing includes two mutually symmetrical guide holes 401 opened in the side wall of the telescopic pipe 301, the two guide holes 401 are slidingly connected with a guide plate 402, and the opposite ends of the two guide plates 402 are connected with the telescopic plate 303.

[0032] It should be noted here that the guide assembly provides a guiding and limiting effect for the movement of the telescopic plate 303.

[0033] Working principle: when the circular object is packaged, first, under the guiding effect of the inclined plate 204, the circular object is placed between the multiple groups of arc-shaped limiting plates 202 that are mutually symmetrical, and under the elastic effect of the telescopic assembly, the arc-shaped limiting plate 202 is in contact with the surface of the circular object, so that the limiting of the circular object is realized.

[0034] After the circular object is limited, the rotation of the rotating disc 102 drives the circular object to move to the sleeving assembly, and the sleeving assembly drives the packaging bag 106 to move close to the circular object. During the movement of the packaging bag 106, when the packaging bag 106 abuts against the rotating ball 203, under the action of the downward movement force of the packaging bag 106 and the interaction force, the arc-shaped limiting plate 202 is pushed away from the packaging bag 106, so that the packaging bag 106 can move around the side of the circular object. When the packaging bag 106 pushes a group of arc-shaped limiting plates 202 away from the circular object, there are still a plurality of groups of arc-shaped limiting plates 202 abutting against the surface of the circular object, so as to ensure the complete wrapping of the packaging bag 106 on the surface of the circular object and realize effective limiting during the packaging of the circular object, thereby reducing the risk of position deviation of the circular object during the packaging process, and further improving the quality of the packaging of the circular object.

[0035] After the packaging bag 106 is sleeved on the surface of the circular object, the cutting mechanism is used to cut the packaging bag 106. The cutting mechanism can use the common cutting method in the prior art, which is not shown here. After the cutting of the packaging bag 106 is completed, the circular object sleeved with the packaging bag 106 can be rotated to the heat sealing assembly under the action of the rotation of the rotating disc 102 for heat sealing. After heat sealing is completed, the packaged circular object can be removed, thereby realizing the cycle operation of feeding, packaging, heat sealing and taking out of the circular object.

[0036] Embodiment 2

[0037] Please refer to Figure 4 The present embodiment further illustrates embodiment 1. The first L-shaped plate 103 in the figure is provided with a sleeving assembly for sleeving the packaging bag 106. The sleeving assembly includes two first air cylinders 501 arranged on the side of the first L-shaped plate 103 close to the packaging bag 106. The output ends of the two first air cylinders 501 are arranged close to the rotating disc 102 and are connected with push rod motors 502. The opposite ends of the two push rod motors 502 are provided with suction cups 503.

[0038] It should be noted that: through the arrangement of the sleeving assembly, the two push rod motors 502 push the suction cups 503 to abut against the surface of the packaging bag 106, and then the surface of the packaging bag 106 is adsorbed under the action of the suction force of the suction cups 503. After the adsorption of the surface of the packaging bag 106 by the suction cups 503 is completed, the two push rod motors 502 drive the two suction cups 503 to move away from the packaging bag 106, so that the packaging bag 106 is expanded under the action of the movement of the two suction cups 503. After the packaging bag 106 is expanded, the two first air cylinders 501 drive the packaging bag 106 to move close to the circular object.

[0039] Embodiment 3

[0040] Please refer to Figure 5 , the second L-shaped plate 104 in the figure is provided with a heat sealing assembly for heat sealing the packaging bag 106, the heat sealing assembly comprises two second air cylinders 601 fixedly connected to the second L-shaped plate 104 near the side of the packaging bag 106, the output ends of the two second air cylinders 601 are arranged near the rotating disc 102 and are connected with a heating plate 602;

[0041] It should be noted here that: through the setting of the heat sealing assembly, under the pushing action of the second air cylinder 601, the heating plate 602 moves reciprocatingly on the circumferential side of the packaging bag 106, so that the packaging bag 106 shrinks and is tightly attached to the surface of the circular object under the radiation of heat, thereby realizing heat sealing of the packaging bag 106.
