Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a quick replacement mechanism of roll roller shell, includes dabber 1, dabber 1 is last to be equipped with keyway 4, stopper 7 and boss 9 from the top down in proper order, the width of keyway 4 equals the width of annular key 5, and annular key 5 swing joint in keyway 4, the fixed stopper 7 that is equipped with of boss 9 up end, and boss 9 activity laminating has special-shaped roller shell 2. Swing joint has annular key 5 in keyway 4, annular key 5 includes first arc piece 50, second arc piece 51 and third arc piece 52, 6 inner chambers of locking ring are all located to first arc piece 50, second arc piece 51 and third arc piece 52, and first arc piece 50, second arc piece 51 and the laminating of the once activity of third arc piece 52. First arc piece 50, second arc piece 51 and third arc piece 52 constitute annular key 5, 5 apical circle diameters of annular key are greater than the base circle diameter, and 5 lateral surfaces of annular key laminate mutually with 6 medial surfaces of locking ring, protruding dabber 1 has cup jointed special-shaped roller shell 2 and altitude mixture control section of thick bamboo 3 from supreme down in proper order, the special-shaped roller shell 2 equals with boss 9 and keyway 4 interval with altitude mixture control section of thick bamboo 3 length sum. By manufacturing a mandrel 1 as a matrix, developing special-shaped roller sleeves 2 with different hole patterns according to different products, and matching a height adjusting cylinder 3 according to the height of the special-shaped roller sleeves 2, the sum of the heights of the special-shaped roller sleeves 2 and the height adjusting cylinder 3 is equal to the distance from a boss 9 on the mandrel 1 to a key groove 4. The inner side surface of the special-shaped roller sleeve 2 is provided with a limiting groove 8 in an annular array, the limiting block 7 is movably connected in the limiting groove 8, and the limiting block 7 is arranged on the outer side surface of the mandrel 1 in an annular array.
