DETAILED DESCRIPTION

[0022] The utility model will be described in further detail below in combination with the drawings and specific embodiment.

[0023] Example one:

[0024] In this embodiment, refer to Figures 1-6A mechanical loose winding roller, which is a specific implementation, comprises a shell 1 and a base 2 for mounting the shell 1, and the shell 1 is mounted on the base 2 through bearings. The shell 1 is provided with a sliding and rotating adjusting shaft 3, the adjusting shaft 3 is provided with a support block 4 which can slide up and down, and the shell 1 is provided with a positioning block 5 which cooperates with the support block 4. The shell 1 cooperates with the adjusting shaft 3 through a key groove, so that the adjusting shaft 3 rotates to drive the shell 1 to rotate. By controlling the sliding of the adjusting shaft 3 in the shell 1, the support block 4 slides up and down, and the effect of quickly loosening the pipe core is realized. The positioning block 5 makes the support block 4 only slide up and down, avoiding the support block 4 sliding in the same direction when the adjusting shaft 3 slides, so as to cause the loosening effect cannot be realized.

[0025] Further, the shell 1 comprises a cylinder body 6 and a cylinder cover 7 which can be combined. The combination of the cylinder body 6 and the cylinder cover 7 makes it more convenient and fast to install the adjusting shaft 3. The cylinder cover 7 is tightly connected with the cylinder body 6 through screws or other fasteners to ensure the stability of the shell 1.

[0026] Further, the support block 4 is provided with a limiting block 8 which cooperates with the positioning block 5, and the shell 1 is provided with a limiting groove 9 which cooperates with the limiting block 8. The positioning block 5 is fixed on the limiting block 8 through screws, and the limiting block 8 cooperates with the limiting groove 9, so that the position of the adjusting shaft 3 on the cylinder body 6 is positioned, avoiding the deviation of the opening corresponding to the support block 4 and the shell 1, so as to cause the loosening effect cannot be realized.

[0027] Further, the adjusting shaft 3 and the support block 4 are respectively provided with a sliding groove 10 and a sliding shaft 11 for mutual cooperation. Through the cooperation of the sliding shaft 11 and the sliding groove 10, when the adjusting shaft 3 slides, the support block 4 can only move along the sliding groove 10, and through the fixation of the positioning block 5, the support block 4 realizes the effect of sliding up and down.

[0028] Further, the base 2 is provided with a rotating motor 12 which cooperates with the adjusting shaft 3. The rotating motor 12 can be connected and cooperated in a direct connection or gear way. In this embodiment, the direct connection way is adopted to connect and cooperate with the adjusting shaft 3. The power of the rotating motor 12 is better transmitted to the adjusting shaft 3. And the rotating speed of the rotating motor 12 can be adjusted to control the tightness of the film during winding.

[0029] Further, the adjusting shaft 3 can realize reciprocating sliding in the shell 1 through components such as air cylinder 13, hydraulic cylinder or cam. In this embodiment, the air cylinder 13 is adopted to control the reciprocating sliding of the adjusting shaft 3. The pneumatic rod can push the motor or the adjusting shaft 3, so as to control the position of the adjusting shaft 3 in the shell 1, realize the quick up and down sliding of the support block 4, and achieve the purpose of adjusting the tightness of the winding roller.

[0030] The utility model discloses a beneficial effect: through the adjustment axle 3 rotation drive support block 4 and shell 1 synchronous rotation, and through the locating piece 5 makes support block 4 only can slide up and down when adjusting axle 3 sliding, thereby realizes the effect of quick loose pipe core.
