[0018] 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.

[0019] Example:

[0020] Please see Figure 1-4A high-frequency heating device for metal cup liners includes a frame 1. A sealing assembly is provided on the upper side of the frame 1. The sealing assembly includes a first lifting device 201, a lifting seat 202, and a sealing chamber 203. A high-frequency heating coil 3 is fixedly connected to the frame 1 within the sealing chamber 203. A feeding rotating assembly is provided on the lower side of the frame 1. The feeding rotating assembly includes a second lifting device 401 and a rotating device 402. A rotating rod 403 is fixedly connected to the rotating end of the rotating device 402. A limit collar 404 and a positioning sleeve 405 are provided at the end of the rotating rod 403. An inflation pipe 5 is fixedly connected to the frame within the sealing chamber 203.

[0021] The first lifting device 201 is specifically a cylinder. The piston rod of the first lifting device 201 extends and retracts to drive the lifting seat 202 to perform lifting and lowering actions, and the sealing chamber 203 fixed on the lifting seat 202 will also rise and fall accordingly. A sealing ring is provided on the frame 1 directly below the sealing chamber 203.

[0022] The second lifting device 401 is specifically a linear module. The second lifting device 401 drives the rotating device 402 to perform lifting actions, thereby loading and unloading the inner liner of the cup. An anti-deviation groove is provided on the rotating rod 403 to prevent relative rotation between the limiting collar 404 and the positioning sleeve 405 relative to the rotating rod 403. The protrusion on the positioning sleeve 405 can match the groove of the inner liner of the cup for positioning, preventing relative rotation between the inner liner of the cup and the positioning sleeve 405 during rotation.

[0023] Multiple air inlets are provided on the inflation pipe 5, and these air inlets are arranged in an array on the inflation pipe 5, which enables nitrogen to be filled into the sealed chamber 203 more quickly and evenly. An exhaust pipe 6 is fixedly connected to the upper part of the sealed chamber 203, and the exhaust pipe 6 is used to discharge internal air when filling with nitrogen.

[0024] The working principle of this utility model is as follows: In use, the inner liner of the cup is placed along the positioning sleeve 405 and the limiting sleeve 404. Then, the piston rod of the first lifting device 201 extends, and the lifting seat 202 descends to abut against the sealing ring to form a seal. Next, nitrogen is injected into the sealing chamber 203 through the air filling pipe 5 for a period of time, and the air inside the sealing chamber is discharged through the exhaust pipe 6. Then, the second lifting device 401 drives the rotating device 402 to rise. During this process, the rotating rod 403 will also rise synchronously. The inner liner of the cup will rise with the rotating rod 403 into the high-frequency electric heating coil 3. After the electric heating coil is energized, it heats the inner liner of the cup. During this process, the optional device 402 will drive the rotating rod 403 to rotate at a low speed to improve the uniformity of the heat treatment of the inner liner of the cup and improve the processing quality.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
