Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.
[0021] Example 1, please refer to Figure 1-Figure 4A raw material internal mixer for the production of resettable fuses includes an internal mixer body 1, two stirring rotors 2 and a workbench 3.

[0022] See also Figure 1-Figure 4 The banburying structure includes: two banburying guide plates 6, a banburying box 7, a discharge port 8, two handle fixing plates 9, and two banburying handles 10; the two banburying guide plates 6 are respectively mounted on the outer wall surfaces of the four guide rods 4, the banburying box 7 is installed on the inner wall surfaces of the two banburying guide plates 6, the discharge port 8 is installed on the upper wall surface of the banburying box 7, the two handle fixing plates 9 are respectively installed on the two side surfaces of the banburying box 7, and the two banburying handles 10 are respectively installed on the front wall surfaces of the two handle fixing plates 9.
[0023] See also Figure 1-Figure 4 The guide structure includes: two hydraulic positioning plates 11, two hydraulic rods 12, two sliding sleeves 13, two telescopic sleeves 14 and two limit sleeves 15; the two hydraulic positioning plates 11 are respectively installed on the two side surfaces of the mixing box 7, the two hydraulic rods 12 are respectively installed on the upper wall surfaces of the two hydraulic positioning plates 11, the two sliding sleeves 13 are respectively installed on the upper wall surfaces of the two hydraulic rods 12, the two telescopic sleeves 14 are respectively installed on the lower wall surfaces of the two sliding sleeves 13, and are connected to the mixing box 7, and the two limit sleeves 15 are respectively installed on the lower wall surfaces of the mixing box 7.
[0024] In this embodiment, the horizontal movement of the mixing box 7 is achieved by two convex guide rails 5 and two sliding rods 16, and the vertical movement of the mixing box 7 is achieved by the cooperation of two hydraulic rods 12 and two telescopic sleeves 14. The electromagnetic coil 22 is used to achieve magnetic adsorption, instead of manually disassembling the mixing box 7 with bolts to strip the material.
[0025] Specifically, the operator pours the raw materials along the discharge port 8, and then inserts the upper push bolt into the discharge port 8 with a hydraulic press, starts the internal mixer body 1, and after the internal mixing is completed, the operator lifts the upper push bolt to disengage the upper push bolt from the discharge port 8, and then turns off the switch of the electromagnetic coil 22 on the internal mixer body 1. After a while, the operator holds the two internal mixing handles 10 with his hands and drags them forward. The two internal mixing handles 10 drive the internal mixing box 7 forward through the two handle fixing plates 9, and the internal mixing box 7 drives the two sliding sleeves 13 to move forward along the two sliding rods 16 through the two telescopic sleeves 14. At the same time, the two limit sleeves 15 move forward along the two convex guide rails 5. When the two internal mixing guide plates 6 are separated from the four guide rods 4, the operator starts the two hydraulic rods 12. The two hydraulic rods 12 move the internal mixing box 7 upward through the two hydraulic positioning plates 11, the two telescopic sleeves 14 shrink, and the two limit sleeves 15 are separated from the two convex guide rails 5.
[0026] Example 2, please refer to Figure 1-Figure 4 The stripping structure includes: two sliding rods 16, a stripping fixing plate 17 and two stripping columns 18; the two sliding rods 16 are respectively installed on the front wall of the internal mixer body 1, the stripping fixing plate 17 is installed on the front wall of the two sliding rods 16, and the two stripping columns 18 are respectively installed on the rear wall of the stripping fixing plate 17.
[0027] See also Figure 1-Figure 4 The sealing structure includes: a sealing plate 19, a guide washer 20 and a sealing handle 21; the sealing plate 19 is installed on the front wall of the mixing box 7, the guide washer 20 is installed on the rear wall of the sealing plate 19, and the sealing handle 21 is installed on the front wall of the sealing plate 19.
[0028] See also Figure 1-Figure 4 The front and rear walls of the mixing box 7 are respectively provided with limiting grooves, in which electromagnetic coils 22 are installed.
[0029] See also Figure 3 The guide washer 20 is a metal washer that can be electromagnetically attracted.
[0030] In this embodiment, the sealing plate 19 is used to reduce the temperature loss inside the mixing box 7. The sealing plate 19 is adsorbed on the mixing box 7 by the electromagnetic coil 22, which can reduce the difficulty of disassembling the sealing plate 19. The two stripping columns 18 are inserted into the mixing box 7 to push out the mixed raw materials in the mixing box 7 and make the mixed raw materials fall into the collection box, which can improve the collection efficiency of the mixed raw materials.
[0031] Specifically, when the switch of the electromagnetic coil 22 on the internal mixer body 1 is turned off, the electromagnetic coil 22 loses its magnetism after a while. The sealing handle 21 is held by hand and dragged outward. The sealing handle 21 drives the sealing plate 19 to move the guide gasket 20 out along the limit groove opened in the internal mixer box 7. When the two hydraulic rods 12 drive the internal mixer box 7 to move upward, the internal mixer box 7 will be aligned with the two stripping columns 18. The operator places a collection box on the workbench 3 to prepare to collect the internal mixer raw materials. After that, the operator holds the two internal mixer handles 10 and continues to drag forward. The two stripping columns 18 are inserted into the internal mixer box 7 to push out the internal mixer raw materials in the internal mixer box 7, so that the internal mixer raw materials fall into the collection box.

It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
