[0002] A paper cup is a paper container made by mechanically processing and bonding the base paper (white cardboard) made of chemical wood pulp, and its appearance is in the shape of a cup.

[0003] Currently, when processing paper cups, a paper cup machine is often used for a series of forming operations. However, when transporting the paper cup machine, four guide rods are often used to form a cylinder to limit and transport the paper cup inside. However, for paper cups of different diameters, the fixed guide rods cannot be adjusted.

[0004] Therefore, an auxiliary device is needed to adapt to the transportation process of paper cups of different diameters. Summary of the Utility Model

[0005] In view of the above defects, the utility model provides an auxiliary forming device for a paper cup machine, which includes a collection seat and four guide rods installed around the collection seat. The collection seat includes a top plate and a bottom plate that are movably connected. A linkage mechanism for changing the positions of the four guide rods is installed between the top plate and the bottom plate. A limiting cylinder is installed at the bottom of the bottom plate, and an airbag for pushing the linkage mechanism after expansion is placed inside the limiting cylinder. The airbag inputs and outputs gas through an air charging pipe connected to the bottom end.

[0006] Further, top holes and bottom holes for easy maintenance are respectively opened in the middle of the top plate and the bottom plate, and the top holes are sealed by a cover plate.

[0007] Further, eight equally spaced inclined sliding grooves are opened on the top plate, and eight equally spaced inclined sliding grooves are opened on the top of the bottom plate, and the ends of the sliding grooves closest to the center of the circle corresponding to the bottom sliding grooves are on the same vertical line.

[0008] Further, the linkage mechanism includes eight water-drop-shaped linkage plates, and one side surface of adjacent linkage plates are mutually fitting inclined surfaces. The linkage plates are respectively inserted into the sliding grooves and the sliding grooves through linkage columns fixed at the top ends and sliders fixed at the bottom ends.

[0009] Further, the guide rods are of an extended rod structure and are threadedly connected to the thread grooves opened in the linkage columns.

[0010] Further, the airbag is a reinforced airbag with double-layer rubber and nylon cloth inside.

[0011] The utility model has the following beneficial effects compared with the prior art:

[0012] According to actual needs, the size of the transmission channel formed between the guide rods during the transmission of paper cups can be adjusted, which has a high adaptation effect. Brief Description of the Drawings

[0017] For the convenience of understanding the present utility model, the device of the present utility model will be described more comprehensively below with reference to the relevant drawings. Embodiments of the device are shown in the drawings. However, the device can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present utility model more thorough and comprehensive.

[0018] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", and "arranged" should be understood in a broad sense. For example, they can be fixedly connected and arranged, or detachably connected and arranged, or integrally connected and arranged. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0019] Embodiment

[0020] As Figures 1-3 shown, this embodiment provides an auxiliary forming device for a paper cup machine, including a collection seat and four guide rods 1 installed around the collection seat. The guide rods 1 are extension rod structures and are threadedly connected to the screw grooves opened in the linkage columns 242. In this embodiment, the connection method of the screw and the screw groove is used to realize the extension of the guide rods 1. The collection seat includes a top plate 21 and a bottom plate 22 that are movably connected. The middle parts of the top plate 21 and the bottom plate 22 are respectively provided with a top hole 26 and a bottom hole 28 for convenient maintenance. The top hole 26 is sealed by a cover plate 23 (the outer ring of the cover plate 23 is provided with threads, and the inner ring of the top hole 26 is provided with a thread groove, and the two can be threadedly connected). A linkage mechanism 24 for changing the positions of the four guide rods 1 is installed between the top plate 21 and the bottom plate 22;

[0021] Specifically, the linkage mechanism 24 includes eight water-drop-shaped linkage plates 241. One side surface of adjacent linkage plates 241 are inclined surfaces that fit together, facilitating synchronous sliding after fitting. The linkage plates 241 are respectively inserted into the sliding grooves 25 and the sliding chutes 27 through the linkage columns 242 fixed at the top ends and the sliders 243 fixed at the bottom ends. The top plate 21 is provided with eight equally spaced inclined sliding grooves 25, and the top of the bottom plate 22 is provided with eight equally spaced inclined sliding chutes 27. The ends of the sliding grooves 25 closest to the center of the circle corresponding to the bottom sliding chutes 27 are on the same vertical line (the inclination angles of the other ends are equal, and the specific angles can be adjusted according to actual needs), ensuring smooth movement.

[0022] A limiting cylinder 3 is installed at the bottom of the bottom plate 22. An airbag 4 for pushing the linkage mechanism 24 after expansion is placed inside the limiting cylinder 3. The airbag 4 is a reinforced airbag with double-layer rubber and nylon cloth inside. The airbag 4 inputs and outputs gas through an air charging pipe 5 connected to the bottom end. Its function is to input gas through an air pump connected to the air charging pipe 5, causing the airbag 4 to expand. Through the limitation of the inner wall of the limiting cylinder 3, it gradually penetrates the bottom hole 28 and until it pushes the middle parts of the respective linkage plates 241, causing them to rotate outwards, so as to change the distance between the guide rods 1 connected at the top, thereby realizing the adaptation of the size of the stored paper cups.

[0023] It should be noted that the structure of the present utility model can be implemented in many different forms and is not limited to the embodiments. Any equivalent transformation made by those of ordinary skill in the art using the description and drawings of the present utility model, or directly or indirectly applied in other related technical fields, such as the loading and unloading of other items, is included in the protection scope of the present utility model.
