Abstract

A kind of paper cutter of efficient removal paper tail, including the first supporting table and the second supporting table, connect between the first supporting table and the second supporting table and have slip lid, the paper roll being cut into a section by specification can move to the second supporting table through slip lid from the first supporting table, slip lid is opened when, opening is formed between slip lid and the first supporting table, the clout of paper roll afterbody can drop through opening, it is provided above self-locking non-return mechanism at slip lid, self-locking non-return mechanism only allows paper roll to move towards the second supporting table from the first supporting table, if paper roll reversely moves, self-locking non-return mechanism Automatic-clamping paper roll.It is an advantage of the invention that the shift position without detecting paper roll, utilize the auto-lock function of self-locking non-return mechanism to be automatically prevented from paper roll and reversely move, the action that prevention paper roll moves is performed without the time, not only increase the speed removing paper tail, and without controlling circuit, reduce the cost of paper cutter.

Description

Efficiently remove the paper cutter of paper tail

Technical field

The present invention relates to cut the paper cutter of paper paper product, the paper tail removal mechanism of the most this paper cutter.

Background technology

Paper cutter for being cut into a section finished roll by strip paper roll by specification.Seeing Fig. 1, paper cutter includes the first supporting table 1 and the second supporting table 2 separated by a distance, and connecting between the first supporting table 1 and the second supporting table 2 has slip lid 3.Slip lid 3 is closed when, slip lid 3 composition is overlapped on the bridge between the first supporting table 1 and the second supporting table 2, and the finished roll 4 being cut into a section by specification can move to the second supporting table 2 through slip lid 3 from the first supporting table 1.Slip lid 3 is opened when, as in figure 2 it is shown, form opening 5 between slip lid 3 and the first supporting table 1, the clout 7(of paper roll afterbody is called for short " paper tail ") can drop through opening 5.After removing paper tail, slip lid 3 is reset to the closed position shown in Fig. 1.In order to prevent during slip lid 3 resets and closes, support paper roll 4 on slip lid 3 back moves with slip lid 3, and existing paper cutter is arranged over baffle plate 11 at slip lid 3, and baffle plate 11 is driven by cylinder 12 can be up and down.During slip lid 3 resets and closes, as in figure 2 it is shown, cylinder 12 drives baffle plate 11 to move down, baffle plate 11 keeps off the end at last coil paper volume 4.But, the action of cylinder 12 requires time for, but also the shift position of sensor to be relied on detection paper roll, thus, not only increase the time removed needed for paper tail, and control complex circuit, add the cost of paper cutter.

Summary of the invention

It is an object of the invention to provide the paper cutter of a kind of efficient removal paper tail.

The main technical schemes that the present invention takes is: the paper cutter of a kind of efficient removal paper tail, including the first supporting table separated by a distance and the second supporting table, connect between the first supporting table and the second supporting table and have slip lid, slip lid is closed when, slip lid composition is overlapped on the bridge between the first supporting table and the second supporting table, the paper roll being cut into a section by specification can move to the second supporting table through slip lid from the first supporting table, slip lid is opened when, opening is formed between slip lid and the first supporting table, the clout of paper roll afterbody can drop through opening, it is provided above self-locking non-return mechanism at slip lid, self-locking non-return mechanism only allows paper roll to move towards the second supporting table from the first supporting table, if paper roll reversely moves, self-locking non-return mechanism Automatic-clamping paper roll.

As preferred forms or alternative, the present invention also can take the most attached technical scheme.

Described self-locking non-return mechanism is the spring leaf tilted, between spring leaf and described slip lid, shape has angle, when paper roll moves towards the second supporting table from the first supporting table when, spring leaf can be bent by paper roll upwards jack-up, if paper roll reversely moves, frictional force between spring leaf and paper roll promotes spring leaf to have reclinate trend, to such an extent as to the frictional force between spring leaf and paper roll increases to be enough to prevent paper roll moves.

Described self-locking non-return mechanism is made up of the friction pulley of the fork suspended in midair and one-directional rotation, friction pulley is arranged on the lower end of fork, when paper roll moves towards the second supporting table from the first supporting table when, fork can be by paper roll upwards jack-up, friction pulley is pressed on paper roll and rotatable, if paper roll reversely moves, the friction pulley being pressed on paper roll maintains static, promote fork to have the trend of swung downward, to such an extent as to the frictional force between friction pulley and paper roll increases to be enough to prevent paper roll moves.

It is an advantage of the invention that the shift position without detecting paper roll, utilize the auto-lock function of self-locking non-return mechanism to be automatically prevented from paper roll and reversely move, the action that prevention paper roll moves is performed without the time, not only increase the speed removing paper tail, and without controlling circuit, reduce the cost of paper cutter.

Detailed description of the invention

Embodiment one

See Fig. 3, according to the paper cutter of a kind of efficient removal paper tail that the present invention provides, including the first supporting table 1 and the second supporting table 2 separated by a distance, connect between the first supporting table 1 and the second supporting table 2 and have slip lid 3.Fig. 3 show slip lid 3 and is in the state of closedown, and now slip lid 3 composition is overlapped on the bridge between the first supporting table 1 and the second supporting table 2, and the paper roll 4 being cut into a section by specification can move to the second supporting table 2 through slip lid 3 from the first supporting table 1.Slip lid 3 is opened when, as shown in Figure 4, forming opening 5 between slip lid 3 and the first supporting table 1, the afterbody clout 7 of paper roll 4 can drop through opening 5.

It is provided above self-locking non-return mechanism at slip lid 3.The self-locking non-return mechanism of the present embodiment is the spring leaf 6 tilted, between spring leaf 6 and slip lid 3, shape has angle, when paper roll 4 moves towards the second supporting table 2 from the first supporting table 1 when, spring leaf 6 can be bent by paper roll 4 upwards jack-up, if paper roll 4 reversely moves, frictional force between spring leaf 6 and paper roll 4 promotes spring leaf 6 to have reclinate trend, to such an extent as to the frictional force between spring leaf 6 and paper roll 4 increases to be enough to prevent paper roll 4 moves, thus can prevent during slip lid 3 resets and closes, support paper roll 4 on slip lid 3 back moves with slip lid 3.

After slip lid 3 is opened, i.e. under Fig. 4 state, may wait for the afterbody clout 7 of previous coil paper volume 4 and the head clout 8 of the follow-up paper roll 4a caught up with all after opening 5 drops, turn off slip lid 3.

Embodiment two

Seeing Fig. 5, the present embodiment is with the difference of embodiment one, and the self-locking non-return mechanism of the present embodiment is made up of the friction pulley 10 of the fork 9 suspended in midair and one-directional rotation, and friction pulley 10 is arranged on the lower end of fork 9.When paper roll 4 moves towards the second supporting table 2 from the first supporting table 1 when, fork 9 can be by paper roll 4 upwards jack-up, and friction pulley 10 is pressed on paper roll 4 and rotatable.If paper roll 4 reversely moves, the friction pulley 10 being pressed on paper roll 4 maintains static, fork 9 is promoted to have the trend of swung downward, to such an extent as to the frictional force between friction pulley 10 and paper roll 4 increases to be enough to prevent paper roll 4 moves, thus can prevent during slip lid 3 resets and closes, support paper roll 4 on slip lid 3 back moves with slip lid 3.Other structures of the present embodiment are identical with embodiment one.
