To sum up, the present invention provides a kind of drum apparatus, and to be engaged with reel, the endoporus of the reel is used to be sheathed on this
On drum apparatus, the roll device includes rotating shaft, fixture and the first expansion plate, the rotating shaft have first end vertically and
Second end, the reel is removed from second end, and the fixture is mutually fixed with the rotating shaft, and the fixture has guidance part, the guiding
Portion has guiding face, and the guiding face is that, along the axially inclined inclined-plane of the rotating shaft, the guiding face has spikes/low- points, the high point
The first end is closed on compared with the low spot, first expansion plate is mutually flexibly connected with the fixture, first expansion plate has outer surface
And the inner surface corresponding with the outer surface, the outer surface is engaged to the endoporus with the reel, and the inner surface has the
One is raised, and first projection is slided to be engaged with the guiding face along the guiding face, wherein, when being sheathed on the cylinder
When the reel on device is applied in the active force of first direction, the reel applies on the first direction to first expansion plate
Frictional force, first expansion plate towards the first direction along the guiding face by the frictional force because being moved so that the drum apparatus
Second state is changed into from first state, when the first state, first projection is engaged with the high point of the guiding face, and this
The distance between one expansion plate and the rotating shaft are the first distance, and first expansion plate supports the endoporus of the reel, that is, apply to make
Firmly to the endoporus for being sheathed on the drum apparatus, the phenomenon that the reel occurs to skid in rotation process is prevented effectively from；In this
During the second state, first projection is engaged with the low spot of the guiding face, the distance between first expansion plate and the rotating shaft
For second distance, wherein, first distance is more than the second distance, has the between first expansion plate and the endoporus of the reel
The appearance profile size distortion in one gap, the i.e. drum apparatus, facilitates the dismounting of the drum apparatus.Compared with prior art, originally
The guiding face of invention is inclined-plane, and user need to only overcome the frictional force between the expansion plate and the guiding face just to make this stretch
First projection of plate is slided along the inclined-plane, needs to overcome barrier force just to make the expansion plate and be somebody's turn to do compared to of the prior art
The relative position of fixture is moved, and user provides less power, such as using one hand, it is possible to easily roll up this
Also easily reset after cylinder is removed from the drum apparatus of the present invention, and the expansion plate slides with respect to the guiding face.
In practical application, the drum apparatus 001 shown in Fig. 1 to Figure 12 of the present invention can be applicable in label machine.Such as
Shown in Figure 13, the structural representation of label machine 002 is disclosed, the label machine 002 includes transmission mechanism 8 and above-mentioned
The first end 11 of the drum apparatus 001 of embodiment, the wherein rotating shaft 1 of the drum apparatus 001 is mutually solid with the transmission mechanism 8
Fixed connection, so that the transmission mechanism 8 is driven the drum apparatus 001.Wherein, the version of the drum apparatus 001 and action are former
Reason can refer to Fig. 1 to Figure 12 and above-described embodiment description, will not be described here.Therefore, when being sheathed on the drum apparatus 001
When the reel is applied in the active force of first direction, the reel applies the frictional force on the first direction to first expansion plate,
First expansion plate towards the first direction along the guiding face by the frictional force because being moved so that the drum apparatus are by the first shape
State is changed into the second state, and when the first state, first projection is engaged with the high point of the guiding face, first expansion plate
It is the first distance with the distance between the rotating shaft, first expansion plate supports the endoporus of the reel, that is, applies forces to set
Located at the endoporus of the drum apparatus, the phenomenon that the reel occurs to skid in rotation process is prevented effectively from；In second state
When, first projection is engaged with the low spot of the guiding face, the distance between first expansion plate and the rotating shaft be second away from
From, wherein, first distance is more than the second distance, has the first gap between first expansion plate and the endoporus of the reel,
I.e. the appearance profile size distortion of the drum apparatus, facilitates the dismounting of the reel, i.e., user's use is singlehanded just can be by useless carbon ribbon
