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.
[0026] Please see Figures 1 to 3 This embodiment of a hot pot base demolding device includes a demolding box 1, a feed inlet 2 opened inside the demolding box 1, and a first conveyor belt 3, a second conveyor belt 4, and a third conveyor belt 5 respectively rotatably installed inside the feed inlet 2. Two demolding frames 6 are fixedly installed on the inner wall of the demolding box 1. An extrusion assembly is provided above the demolding frame 6. A drive mechanism for driving the extrusion assembly is provided outside the demolding box 1. The extrusion assembly includes a mounting frame 7 fixedly connected to the outside of the demolding box 1. A fixing rod 8 is fixedly connected inside the mounting frame 7. Two sliders 9 are slidably connected to the outside of the fixing rod 8. A return spring 10 is fixedly installed between the two sliders 9. A clamping block 11 is fixedly connected to the bottom of each of the two sliders 9. A demolding module 12 is fixedly installed on the opposite side of the two clamping blocks 11.
[0027] The return spring 10 is connected to the outside of the fixed rod 8, and the two demolding modules 12 are located on the upper surfaces of the demolding frame 6 and the first conveyor belt 3. Under the action of the return spring 10, the two demolding modules 12 can achieve uniform extrusion of the mold, effectively improving the demolding effect. The setting of the return spring 10 ensures the stability and reliability of the demolding modules 12 during the movement process, avoiding mold damage or incomplete demolding caused by uneven extrusion pressure.
[0028] Specifically, the mounting bracket 7 has two guide shafts 13 fixedly connected inside, and the two sliders 9 are slidably connected to the outside of the two guide shafts 13. By setting the guide shafts 13, the sliders 9 are more stable during sliding, ensuring the movement accuracy of the demolding module 12 and further improving the demolding quality.
[0029] Please see Figures 1 to 3 In this embodiment, the driving mechanism includes a mounting base 16 fixedly connected to the outside of the mounting frame 7. A drive motor 17 is fixedly mounted on the back of the mounting base 16. A rotating disk 18 is fixedly connected to the output shaft of the drive motor 17. A pulley 19 is rotatably connected to the outside of the rotating disk 18, and a sliding rod 20 is slidably connected to the outside of the pulley 19. By adjusting the speed of the drive motor 17, the demolding requirements of molds of different specifications can be easily adapted.
[0030] The bottom end of the slide bar 20 is fixedly connected to a fixing plate 15, and two connecting rods 14 are hinged to the bottom of the fixing plate 15. The end of the connecting rod 14 away from the fixing plate 15 is hinged to the upper surface of the slider 9 through a hinge seat, and the two connecting rods 14 are symmetrically distributed on the top of the two sliders 9.
[0031] Specifically, the outer diameter of the pulley 19 is matched with the inner diameter of the slide rod 20, and both the slide rod 20 and the connecting rod 21 are oscillatingly connected to the outside of the rotating disk 18. The mounting bracket 7 has a moving hole inside that matches the connecting rod 21.
[0032] Please see Figure 1 In this embodiment, the outside of the demolding box 1 is provided with a mold discharge port 22 and a bottom material discharge port 23 in sequence. The first conveyor belt 3 is arranged between the inlet 2 and the mold discharge port 22 in sequence. The second conveyor belt 4 is used to output the demolded hot pot base material from the bottom material discharge port 23. The second conveyor belt 4 is located inside the bottom material discharge port 23. The third conveyor belt 5 is located on the lower side of the mold discharge port 22 for outputting the demolded mold.
[0033] The demolding box 1 is externally mounted with a servo motor 24 for driving the second conveyor belt 4. The output shaft of the servo motor 24 is fixed to one end of one of the conveyor rollers of the second conveyor belt 4. Both the second conveyor belt 4 and the third conveyor belt 5 have drive wheels 25 fixedly mounted at their ends away from the demolding box 1. A synchronous belt 26 connects the two drive wheels 25. By setting the second conveyor belt 4 and the third conveyor belt 5 to achieve synchronous transmission via the drive wheels 25 and the synchronous belt 26, the demolded base material and the mold can be output synchronously, improving production coordination and efficiency.
[0034] The working principle of the above embodiments is as follows:
[0035] In use, the mold of the hot pot base to be demolded is inverted and enters the demolding box 1 from the feed port 2 via the first conveyor belt 3. Under the push of the subsequent mold, it moves towards the mold discharge port 22, preparing for demolding. The drive motor 17 is started by the controller, and the output shaft of the drive motor 17 drives the rotating disk 18 to rotate. The pulley 19 on the rotating disk 18 slides on the slide rod 20. Since the outer diameter of the pulley 19 is matched with the inner diameter of the slide rod 20, the slide rod 20 swings under the action of the pulley 19. When the slide rod 20 swings, it pushes the slider 9 to make linear reciprocating motion on the fixed rod 8 through the connecting rod 14. The return spring 10 between the two sliders 9 plays a reset role, allowing the slider 9 to move in the opposite direction. The slider 9 drives the clamping block 11 and the demolding module 12 to move. When the two demolding modules 12 are relatively close, they squeeze the mold located on the demolding frame 6, causing the mold to separate from the hot pot base; when the two demolding modules 12 are relatively far apart, they are reset under the action of the return spring 10, waiting for the next squeeze. After demolding, the hot pot base material falls from the base material outlet 23 onto the second conveyor belt 4 and is output by the second conveyor belt 4; after demolding, the mold falls from the mold outlet 22 onto the third conveyor belt 5 and is output by the third conveyor belt 5.

Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply.
