The dismounting device for core roll dismounting is capable of ejecting the core roll 70 from the core roll housing 80 by means of the pushing portion 21 on the driving device 20. When the core roller 70 needs to be replaced, the core roller 70 and the core roller sleeve 80 do not need to be integrally disassembled, so that a large amount of manpower and material resources are saved, the disassembling and maintaining time of the core roller 70 is greatly shortened, and the influence on production is greatly reduced. Meanwhile, with the dismounting device of the example of the present embodiment, only the relative movement between the core roll 70 and the core roll shell 80 exists during the dismounting process of the core roll 70, so that the bearing 90 outside the core roll shell 80 is not damaged during the dismounting process.

In this embodiment, the fixed supporting frame 10 includes a fixed plate 11 and a plurality of supporting rods 12, the driving device 20 is fixed on the fixed plate 11, and the plurality of supporting rods 12 are uniformly arranged on the fixed plate 11 around the driving device 20. Through fixing drive arrangement 20 on fixed plate 11, and a plurality of bracing pieces 12 evenly arrange on fixed plate 11, can ensure drive arrangement 20's stability, ensure simultaneously that pushing part 21 direction of motion is unanimous with the axial direction of core roller 70, can not cause wearing and tearing to core roller shell 80 when guaranteeing pushing part 21 promotion core roller 70, ensure the size precision of core roller shell 80, further reduce and dismantle cost of maintenance.

In one embodiment, the specific structure of the fixing plate 11 and the plurality of supporting rods 12 may be one of the following embodiments:

example 1: the fixing plate 11 is integrally formed with the plurality of support rods 12 and has an integrated structure, so that the stability of the fixing support frame 10 can be enhanced.

Example 2: the fixing plate 11 and the plurality of supporting rods 12 are respectively and independently formed, and the plurality of supporting rods 12 are fixed on the fixing plate 11 after forming, so that the processing and production are convenient. The plurality of support rods 12 may be fixed to the fixing plate 11 by riveting, welding, or bolting, for example.

In one embodiment, the dismounting device further comprises a base plate 30, the base plate 30 is fixed on the core roller sleeve 80, and the fixed support frame 10 is connected with the base plate 30. By providing the bottom plate 30, the fixing support frame 10 can be better fixed to the core roller housing 80, and the fixing support frame 10 can be conveniently detached.
