[0011] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0012] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0014] like Figures 1-2As shown, a paper cup holder thermoforming device includes a frame 1, an upper mold assembly 2, a lower mold assembly 3, and a worktable 4. The upper mold assembly 2 includes an upper mold 21 and a first lifting member 22. The first lifting member 22 is installed on the top of the frame 1, with its output end facing downwards and connected to the upper mold 21. The lower mold assembly 3 includes a lower mold base 31, a thermoforming mold 32, and a second lifting member 33. The second lifting member 33 is installed at the bottom of the frame 1, with its output end facing upwards and connected to the lower mold base 31. Several thermoforming molds 32 are installed on the lower mold base 31. The worktable 4 is located in the middle of the frame 1, between the upper mold 21 and the lower mold base 31. The middle part of the worktable 4 is hollowed out corresponding to the thermoforming mold 32. Specifically, in this embodiment, the frame 1 adopts a frame structure with high structural strength. The upper mold assembly 2 includes an upper mold 21 and a first lifting member 22. The first lifting member 22 is used to drive the upper mold 21 to lift and close the mold. In this design, the first lifting member 22 specifically uses a cylinder as the power source. In other embodiments, a lead screw, electric push rod, etc. can also be used as alternatives. The lower mold assembly 3 includes a lower mold base 31, a hot pressing mold 32, and a second lifting component 33. The second lifting component 33 uses hydraulic power output or a gear and spur gear combination at the motor output end for lifting, ensuring smooth lifting of the lower mold base 31 with good stability. Several hot pressing molds 32 are mounted on the lower mold base 31. When the hot pressing molds 32 and the upper mold 21 are closed, several cup holders can be hot-pressed in one operation. The lower mold base 31 serves as a support for the hot pressing molds 32, allowing them to lift synchronously. The worktable 4 is located in the middle of the frame 1 and has a hollow center, facilitating the closing of the hot pressing molds 32 with the upper mold 21 through the hollow. The worktable 4 can also support the raw material. After the upper mold 21 and the hot pressing molds 32 are closed, several cup holders are hot-formed in one operation. This automated, integrated molding process, with the upper mold and hot pressing mold capable of lifting and lowering, facilitates demolding. The workpieces are removed, and multiple cup holders are formed in one operation before cutting, improving production efficiency.

[0015] like Figures 1-2 As shown, the machine also includes air-cooled fans 5. Several of these air-cooled fans 5 are installed side-by-side at intervals on the side of the frame 1. The air outlets of the air-cooled fans 5 are angled downwards, facing the hollowed-out area of ​​the worktable 4. Specifically, the two rows of air-cooled fans 5 blow air downwards on the formed workpiece to cool it, preventing it from being blown away. Water cooling is not used, thus avoiding moisture and deformation. The high-speed airflow from the air-cooled fans 5 blows in opposite directions, resulting in a large air volume, preventing the workpiece from absorbing water and becoming damp, and simplifying maintenance.

[0016] like Figure 1 As shown, a vacuum adsorption head 41 is provided on the edge of the workbench 4. Specifically, after the material is loaded, the vacuum adsorption head 41 is used to firmly adsorb the edge of the plate-shaped raw material to be hot-pressed onto the workbench 4, so as to prevent the workpiece from shifting when the upper mold 21 and the hot pressing mold 32 are closed, and to prevent it from being blown off course by the high speed when the air-cooling fan 5 is used to cool the workpiece.

[0017] like Figures 1-2 As shown, guide posts 11 are provided on the inner side of the frame 1, and the guide posts 11 movably pass through the four corners of the upper mold 21. Specifically, the guide posts 11 are used to restrict the upper mold 21 and prevent the upper mold 21 from deviating when the first lifting component 22 drives the upper mold 21 to rise and fall.

[0018] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
