The clutch mechanism 1 in the above embodiment includes the input gear 11, the output gear 13, and the clutch gear 12, the clutch gear 12 is movably disposed and can slide in the circular arc-shaped guide slot 150, and the clutch gear 12 is always engaged with the input gear 11 because the center of the circular arc-shaped guide slot 150 coincides with the axis of the input gear 11. When the film is rolled, the clutch gear 12 is positioned at the output position, the input gear 11 is meshed with the clutch gear 12, the clutch gear 12 is meshed with the output gear 13, the film tearing rod 4 connected with the output gear 13 rotates to roll the film, and the clutch gear 12 is always kept at the output position under the backstop of the inner wall of the circular arc-shaped guide groove 150; when the clutch mechanism 1 is switched from the film winding state to the film unwinding state, the input gear 11 rotates reversely, the clutch gear 12 revolves around the input gear 11 along the circular arc-shaped guide groove 150 while rotating, until the clutch gear 12 reaches the clutch position, and the clutch gear 12 is disengaged from the output gear 13 in the process of revolution; when the film is removed, the clutch gear 12 is kept at the clutch position under the backstop of the inner wall of the circular arc-shaped guide groove 150, the clutch gear 12 is always separated from the output gear 13, the output gear 13 can freely rotate, and the film coiled on the film tearing rod 4 can be freely pulled out. The clutch mechanism 1 has fewer components, stable motion and lower cost, and can switch the film winding state and the film unwinding state through the forward and reverse rotation of the input gear 11.
The position of the axis of the clutch gear 12 at the output position is the output point, that is, when the clutch gear 12 is at the output position, the position of the axis of the clutch gear 12 is the output point. The position of the axis of the clutch gear 12 at the clutch position is a clutch point, that is, when the clutch gear 12 is at the clutch position, the position of the axis of the clutch gear 12 is a clutch point.
Referring to fig. 1 and 3, in one embodiment of the clutch mechanism 1, the axial center of the input gear 11, the output point, and the axial center of the output gear 13 are disposed non-collinearly, and in the film winding state, the axial center of the input gear 11, the axial center of the clutch gear 12, and the axial center of the output gear 13 are disposed non-collinearly. If the axis, the output point and the axis of the output gear 13 of the input gear 11 are not arranged in a collinear manner, the rotation dead point can be avoided, so that the normal rotation of the clutch gear 12 can be ensured, one side of the clutch gear 12 is acted by the acting force of the input gear 11, the other side of the clutch gear 12 is acted by the acting force of the output gear 13, the directions of the acting forces on the two sides of the clutch gear 12 are the same, the acting points are all on the periphery of the clutch gear 12, after the two acting forces are combined to the axis of the clutch gear 12, the rotation moments corresponding to the two forces can be mutually offset, the rotation dead point is generated, and the centrifugal gear 12 is blocked and cannot move. When the axis of the input gear 11, the output point and the axis of the output gear 13 are arranged in a non-collinear manner, the acting force of the input gear 11 on the clutch gear 12 and the acting force of the output gear 13 on the clutch gear 12 are different in direction, the two acting forces have a certain included angle, and after the two acting forces are synthesized to the axis of the clutch gear 12, the rotating moments corresponding to the two acting forces cannot be mutually offset, so that the clutch gear 12 can rotate back and forth, and the clutch gear can be prevented from being locked.
In another embodiment of the clutch mechanism, the axial center of the input gear 11, the output point, and the axial center of the output gear 13 may be arranged collinearly.
In one embodiment of the clutch mechanism, the rotation axes of the input gear 11, the clutch gear 12 and the output gear 13 are all parallel to the horizontal plane or form an acute angle with the horizontal plane, the output gear 13 is arranged above the input gear 11, and the output point is arranged between the output gear 13 and the input gear 11. The output gear 13 has a pressure force acting on the clutch gear 12, and the clutch gear 12 has a pressure force acting on the input gear 11.
In another embodiment of the clutch mechanism, the rotation axes of the input gear 11, the clutch gear 12 and the output gear are all arranged vertically or at an obtuse angle to the vertical direction.
Referring to fig. 1 to 4, in one embodiment of the clutch mechanism 1, the clutch mechanism 1 further includes an auxiliary gear 14, the clutch gear 12 is engaged with the input gear 11 and the auxiliary gear 14 when in the clutch position, and the auxiliary gear 14 is disposed to make the movement of the clutch gear 12 in the clutch position more stable. Moreover, when the clutch mechanism 1 is switched from the film unwinding state to the film winding state, the auxiliary gear 14 has an auxiliary and pushing effect on the movement of the clutch gear 12 towards the output position, so that the efficiency of the clutch mechanism 1 is higher when the states are switched. Particularly, when the output gear 13 is disposed above the input gear 11 and the output point is disposed between the output gear 13 and the input gear 11, the gears are pressed against each other by gravity, and the auxiliary gear 14 is disposed so that the clutch gear 12 can be smoothly switched from the clutch position to the output position.

When the axis of the input gear 11, the clutch point and the axis of the auxiliary gear 14 are arranged non-collinearly, the direction of the acting force of the input gear 11 on the clutch gear 12 and the direction of the acting force of the auxiliary gear 14 on the clutch gear 12 are not arranged in opposite directions, so that a part of radial force is inevitably generated after the two forces are combined, the radial force applied to the clutch gear 12 can cause the clutch gear to move in the circular arc-shaped guide groove 150, the film removing state cannot be maintained, and the reliability of the clutch mechanism 1 is reduced.

Optionally, the clutch point is located on the film withdrawing line 102, that is, the axis of the input gear 11, the clutch point and the axis of the auxiliary gear 14 are arranged in a collinear manner; alternatively, the clutch point may be located within the clutch region as long as the clutch region is not crossed.
Referring to fig. 4, the inner walls of the two ends of the circular arc guide groove 150 are circular arc-shaped, so that the fixing shaft of the clutch gear 12 can contact the inner wall of the circular arc guide groove 150 when moving to the two ends of the circular arc guide groove 150, thereby preventing the fixing shaft of the clutch gear 12 from colliding with the inner wall of the circular arc guide groove 150, and enabling the movement of the clutch gear 12 to be smoother.
