[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example

[0018] Please see Figures 1-3The diagram illustrates a clamping device for packaging plastic slippers bags. It includes a base 1, a rotating rod 2 in the center of the base 1, a motor 3 fixedly connected to one end of the rotating rod 2, a set of symmetrical first connecting rods 4 in the center of the rotating rod 2, a fixing plate 5 on one side of the first connecting rod 4, a connecting block 6 slidably connected to the fixing plate 5, a clamping block 7 on the top of the connecting block 6, and a spring 8 on one side of the connecting block 6. This invention utilizes a rotating rod installed in the center of the base, with one end fixedly connected to the motor. A set of symmetrical connecting rods is located in the center of the rotating rod, and the connecting rods are fixedly connected to the fixing plate. The fixing plate is slidably connected to the connecting block. A clamping block is installed on the top of the connecting block, and the clamping block is connected to the fixing plate via gears. When it is necessary to fix the opening of the plastic bag, operating the gears allows the clamping block to tightly clamp the opening of the plastic bag, thereby achieving a fixing effect and effectively solving the problems of unstable fixing of the plastic bag opening and easy loosening after expansion.

[0019] Furthermore, a set of first connecting rods 4, with one end passing through the inner side of the base 1 and extending to the outer side of the base 1 for sliding connection, are arranged in a Z-shape. The connecting rods allow one end to pass through the inner side of the base and extend to the outer side, enabling the connecting rods to slide freely inside the base. This increases the flexibility and adjustability of the device and allows it to adapt to plastic bag openings of more different sizes and shapes, thus expanding the device's application range.

[0020] Furthermore, a limiting groove 401 is provided on the side of the first connecting rod 4 near the connecting block 6. The limiting groove 401 is slidably connected to the connecting block 6. The connecting block can slide freely in the limiting groove, so that the connecting block can be finely adjusted according to the size and position of the plastic bag opening. This ensures that the plastic bag opening can be accurately and stably fixed between the clamping blocks, improving the accuracy and efficiency of packaging and reducing packaging errors caused by unstable fixing.

[0021] Furthermore, a set of parallel second connecting rods 601 are fixedly connected to one side of the connecting block 6. One end of the set of second connecting rods 601 tightly presses against one end of the spring 8, and the other end of the second connecting rods 601 passes through the fixing plate 5 and is fixedly connected to one side of the connecting block 6. The parallel connecting rods fixedly connected to one side of the connecting block cooperate with the spring and the fixing plate to provide a stable clamping force and a good buffering effect, while ensuring a solid foundation for the clamping block to rotate.

[0022] Furthermore, a connecting gear plate 501 is provided on one side of the fixed plate 5. The gear plate 501 is rotatably connected to the clamping block 7. Through the rotatable connection between the gear plate and the clamping block, the clamping block can be flexibly adjusted.

[0023] Furthermore, the clamping block 7 includes a rotating gear 701 and a clamping plate 702. The central shaft of the rotating gear 701 is rotatably connected to the top of the connecting block 6, and the middle gear of the rotating gear 701 meshes with the gear plate 501. Through the design of the clamping block including the rotating gear and the clamping plate, precise rotational adjustment is achieved to enable the clamping of the packaging bag opening.

[0024] In this solution, the workflow is as follows: When the motor starts, it drives the rotating rod to rotate. The rotating rod drives a set of symmetrical connecting rods in the middle to move to both sides. Then, the connecting block first contacts the inner wall of the plastic bag. Then, the top of the connecting block is equipped with a clamping block that is connected to the fixing plate through gears. Then, the clamping block rotates to stably fix the outer wall of the plastic bag in conjunction with the connecting block.
