[0019] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0020] The present application is used to produce a special-shaped thermos cup, which has multiple inner liner 20, and the shape of the inner liner 20 is multiple regular arc segments connected, such as Figure 1As shown, a special-shaped thermos cup welding machine includes a frame 1, a support mechanism 2, a positioning mechanism 4, and a rotating mechanism 6. The frame 1 serves as a carrier for carrying the support mechanism 2, the positioning mechanism 4, and the rotating mechanism 6. The support mechanism 2 includes a positioning die 3, which is used to carry and position the thermos cup shell 18. The positioning mechanism 4 includes a positioning pin 5, which is used to position the cup rim 19 and the inner liner 20 within the thermos cup shell 18. The rotating mechanism 6 includes an eccentric rotating disk 7, which is used to drive the thermos cup shell 18 to rotate to facilitate welding the cup rim 19 and the inner liner 20. The design of the eccentric rotating disk 7, combined with the welding mechanism, can achieve welding of multiple regular arcs.

[0021] like Figure 1 and Figure 2 As shown, the positioning mechanism 4 includes a positioning drive 8, a positioning rod 9, a positioning pin 5 and a positioning plate 10. The positioning drive 8 is arranged at the upper end of the frame 1, the positioning rod 9 is arranged at the output end of the positioning drive 8, and the positioning pin 5 is arranged at the lower end of the positioning rod 9. Therefore, the positioning drive 8 can control the vertical lifting of the positioning pin 5 through the positioning rod 9 to achieve the pressing of the cup rim 19 and the inner liner 20 into the thermos cup shell 18.

[0022] Furthermore, in order to improve the stability of the vertical lifting of the positioning pin 5, we designed a positioning plate 10. The four corners of the positioning plate 10 are slidably set on the connecting column of the frame 1. The positioning plate 10 can play a guiding role when the positioning pin 5 moves, so that the positioning of the positioning pin 5 is more accurate. The positioning pin 5 is detachably set in the middle of the positioning plate 10 through a clamping structure or screws, and the positioning rod 9 is fixedly connected to the positioning plate 10.

[0023] Furthermore, a positioning groove 12 is provided on the positioning pin 5, and the positioning groove 12 is adapted to the shape of the cup rim 19 and the inner liner 20. When the positioning pin 5 abuts the cup rim 19 and the inner liner 20, the bottom of the positioning groove 12 abuts the cup rim 19, and the groove wall of the positioning groove 12 abuts the inner liner 20. The groove width of the positioning groove 12 is adapted to the model of the thermos cup, and the cup rim 19 and the inner liner 20 can be accurately aligned and pressed into the thermos cup shell 18.

[0024] like Figure 1 and Figure 2 As shown, the support mechanism 2 includes a support base 13, a support driving member 14, a support rod 15 and a positioning mold 3. The support base 13 is arranged on the frame 1 and can also be a part of the frame 1. The support driving member 14 is arranged below the support base 13. The support rod 15 is movably arranged at the output end of the support driving member 14. The positioning mold 3 is arranged on the support base 13. The support rod 15 is used to connect the positioning mold 3. Therefore, the support driving member 14 can control the vertical lifting of the positioning mold 3 through the support rod 15, and cooperate with the positioning mechanism 4 to press the thermos cup shell 18.

[0025] like Figure 1and Figure 2 As shown, the rotating mechanism 6 includes a rotating drive member 16 and an eccentric rotating disk 7. The rotating drive member 16 is arranged on the side of the support base 13, and the eccentric rotating disk 7 is arranged at the upper end of the support base 13 and is located below the positioning mold 3. The support rod 15 is inserted at the center of the eccentric rotating disk 7, which passes through the eccentric rotating disk 7 and is connected to the positioning mold 3. The rotating drive member 16 is set as a servo motor, which is used to control the eccentric rotating disk 7 to rotate precisely at a set rate. The design of the eccentric rotating disk 7 enables the special-shaped thermos cup to rotate according to a specific path, and cooperates with the welding mechanism to realize the production of special-shaped thermos cups.

[0026] like Figure 3 As shown, a fixing groove 17 is provided on the surface of the eccentric rotating disk 7. When the positioning mold 3 is installed on the eccentric rotating disk 7, its lower end is placed in the fixing groove 17. The positioning mold 3 is detachably arranged on the eccentric rotating disk 7 through a snap-fit ​​structure.
