[0040] In this embodiment, as shown in Figure 3 The transmission structure 230 includes a base 231, a housing 232, and a transmission part. The base 231 and the housing 232 are fixedly connected by bolts and form an internal mounting space. The transmission part is assembled in the mounting space and is used to drive the execution structure to move radially on the housing 232, so as to position and fix the heat preservation container.

The rotation of the transmission disc 233 can drive the execution structure to move radially on the housing 232, so as to fix the heat preservation container.

[0042] In this embodiment, the edge of the transmission disc 233 is rotationally assembled through the step on the inner wall of the housing 232. The upper surface of the transmission disc 233 has a vortex-shaped groove 2331, and the lower surface has a plurality of teeth 2332. The second gear 235 is in meshing connection with the teeth on the lower surface of the transmission disc 233, so that when the second power source 234 works, it can drive the transmission disc 233 to rotate.

[0043] In this embodiment, as shown in Figures 3-4 The execution structure includes a plurality of execution parts 240, preferably three. The three execution parts 240 are distributed at equal angles on the transmission structure 230, so that the heat preservation container can be more stably fixed.

[0044] In this embodiment, each execution part 240 is the same structure. One of them is taken as an example for description as follows:

[0045] The execution piece 240 comprises a moving block 241 and a clamping block, and the shell 232 is provided with a sliding groove, and the moving block 241 is slidably installed in the sliding groove through a guide groove, so that the moving block 241 can stably slide on the shell 232. The bottom of the moving block 241 is provided with a vortex tooth 242 corresponding to the vortex groove 2331, so that when the transmission disc 233 rotates, the moving block 241 can be moved in the sliding groove.

[0046] In the embodiment, the upper surface of the moving block 241 is flush with the upper surface of the shell 232, so as to facilitate the placement of the stainless steel heat preservation container 300.

[0047] In the embodiment, the clamping block comprises a fixed column 243 and a wedge-shaped block 244, the wedge-shaped block 244 is fixedly connected to the upper end of the fixed column 243, the lower end of the fixed column 243 is provided with a clamping block, and the moving block 241 is provided with a clamping groove, the clamping block is arranged in the clamping groove, so as to fix the clamping block on the moving block 241. The inner and outer sides of the wedge-shaped block 244 are respectively matched with the inner wall and the outer surface of the stainless steel heat preservation container 300, so that when the moving block 241 moves, the wedge-shaped block 244 can fasten the stainless steel heat preservation container 300.

[0048] In the embodiment, the inner and outer sides of the wedge-shaped block 244 are respectively matched with the inner wall and the outer surface of the heat preservation container, that is, the clamping block can fix the stainless steel heat preservation container 300 in different placement modes; that is, the inner wall of the cup opening of the stainless steel heat preservation container 300 can be fixed, and the outer surface of the cup bottom of the heat preservation container can also be fixed, so as to improve the versatility. In order to reduce the damage to the stainless steel heat preservation container 300, a flexible material such as high-temperature-resistant rubber material, high-temperature-resistant sponge and high-temperature-resistant cloth can be coated on the wedge-shaped block 244.

[0049] In the embodiment, as Figures 1-2As shown, the execution structure further comprises a linkage 250 for fixing the upper part of the stainless steel heat preservation container 300. The linkage 250 comprises a transmission belt 252, a reciprocating screw rod 251, a guide rod 257, a sliding block 253 and a pressing plate. The reciprocating screw rod 251 is rotatably installed on the workbench 100, the transmission belt 252 is tensioned between the reciprocating screw rod 251 and the driving structure, and is used to drive the reciprocating screw rod 251 to rotate. The sliding block 253 is screwed on the threaded section of the reciprocating screw rod 251, and the guide rod 257 is arranged on the workbench 100 and passes through the sliding block 253, so that when the reciprocating screw rod 251 rotates, the sliding block 253 can be driven to reciprocate along the reciprocating screw rod 251. The pressing plate is connected to the sliding block 253, so that when the sliding block 253 moves, the pressing plate can be driven to move downward, thereby fixing the top of the stainless steel heat preservation container 300, cooperating with the execution member 240 to position and fix the bottom of the stainless steel heat preservation container 300, so that both ends of the heat preservation container can be fixed, so as to simultaneously roll the inner wall and outer surface of the stainless steel heat preservation container 300.

[0050] In the embodiment, the reciprocating point on the reciprocating screw rod 251 is provided with a limiting ring 258 for limiting the movement distance of the sliding block 253.

[0051] In the embodiment, the pressing plate comprises a first pressing plate 254, a spring 255 and a second pressing plate 256. The first pressing plate 254 is fixedly connected with the sliding block 253 through a pressing arm, and the second pressing plate 256 is connected below the first pressing plate 254 through the spring 255, so that when the sliding block 253 drives the first pressing plate 254 to move, the second pressing plate 256 can be driven to move, thereby tightly fixing the upper part of the heat preservation container. And through the arrangement of the spring 255, there is a gap between the first pressing plate 254 and the second pressing plate 256, which facilitates the reciprocating screw rod 251 to have enough pressure to press the heat preservation container before reciprocating.

[0052] In the embodiment, in order to avoid that the pressing plate damages the surface of the stainless steel heat preservation container 300, the lower surface of the second pressing plate 256 is bonded with an elastic block. The elastic block can be a rubber elastic block, a high-temperature-resistant rubber material, a high-temperature-resistant sponge, a high-temperature-resistant cloth, etc.

[0053] In the embodiment, when the transmission belt 252 is tensioned between the reciprocating wire rod 251 and the driving structure, a tension pulley is connected to the inner side of the one-way gear 222 through the connecting sleeve 2221, the tension pulley is rotatably sleeved with the output shaft of the first power source 221, and the reciprocating wire rod 251 is also provided with a tension pulley. The transmission belt 252 is tensioned between the two tension pulleys, so that when the output shaft of the first power source 221 rotates in the forward direction, the transmission structure 230 and the heat preservation container can be driven to rotate by the one-way gear to facilitate rolling. At this time, the reciprocating wire rod 251 does not rotate, and when the output shaft of the first power source 221 reversely rotates, the reciprocating wire rod 251 can be driven to rotate, so that the pressing plate can tightly fix the upper part of the heat preservation container.

[0054] In the embodiment, the first power source 221 and the second power source 234 can be servo motors, speed reducer motors, etc.

[0055] In the embodiment, as shown in Figure 5 In order to facilitate rolling of the inner wall and the outer surface of the heat preservation container, the first rolling structure 400 and the second rolling structure 500 are arranged on the workbench 100. The first rolling structure 400 passes through the pressing plate and is located on the inner wall of the stainless steel heat preservation container 300 through the telescopic rod, and the second rolling structure 500 is arranged on the outer surface of the stainless steel heat preservation container 300 through the telescopic rod. Therefore, after the stainless steel heat preservation container 300 is fixed, the inner and outer surfaces thereof can be rolled to form textures or patterns.

[0056] In the embodiment, the first rolling structure 400 and the second rolling structure 500 can be existing knurling equipment or rolling equipment, such as a knurling machine, an embossing machine, a stainless steel hydraulic rolling machine, a small-sized numerical control rolling machine, etc. The first rolling structure 400 and the second rolling structure 500 can also be selected according to actual conditions.
