Technical field
The utility model relates to coiling material processing machinery field, especially a kind of coreless rolls rewinding paper breaking mechanism.
Background technique
Coreless rolls are exactly the paper roll of not paper tube core as its name suggests, can greatly reduce body compared with having paper tube core paper roll
Product is convenient for storage and transport.Existing coreless rolls are generally produced by following two mode, the first is first with wind-up roll pair
Paper handkerchief is wound, and paper roll is flattened to wind-up roll extraction again after winding；Second is to form paper handkerchief on rewinding machine
Roll set forms core after gauffer, then carries out rewinding to paper and form coreless rolls.
Such as application No. is 201610807298.6 patent of invention disclose can local modulation break cardboard coreless rolls
Rewinding machine, the disclosure of the invention it is a kind of can local modulation break the coreless rolls rewinding paper breaking mechanism of cardboard, including upper rewind roll, under
Rewind roll and pressure roller, wherein rewinding area is formed between the upper rewind roll, lower rewind roll and pressure roller three, in the rewinding area
Paper feeding direction upstream be hinged with upper rewind roll cooperation integral type arc lateral paper guide, the integral type arc lateral paper guide is at it
Front end is equipped with disconnected cardboard, while being connected with multiple axial directions along upper rewind roll in the nose threads of the integral type arc lateral paper guide
The adjusting bolt of arrangement, the adjusting bolt top are broken cardboard bottom and are bonded with the part adjusted between disconnected cardboard and upper rewind roll
Degree, while the integral type arc lateral paper guide is also configured with and drives its swing mechanism for making period reciprocally swinging, by swinging one
Formula arc lateral paper guide makes disconnected cardboard compress or leave rewind roll, carries out top drawing to disconnected cardboard using bolt is adjusted to disconnected paper
Compactness between plate and upper rewind roll carries out local modulation.
The invention carries out top to disconnected cardboard using adjusting bolt and draws to the compactness between disconnected cardboard and upper rewind roll
Local modulation is carried out, structure is complicated, and installation and debugging difficulty is larger, operation and maintenance higher cost.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of coreless rolls eased for structural principle
Rewinding paper breaking mechanism.
To achieve the goals above, the utility model adopts the following technical solution:
The coreless rolls rewinding paper breaking mechanism includes upper rewind roll, lower rewind roll and rides roller, wherein the upper rewind roll, under
Rewind roll and formation rewinding area is ridden between roller three, had and the cooperation of upper rewind roll in the paper feeding direction upstream in the rewinding area
Air roll, when paper roll reaches setting value, riding roller can accelerate, while air roll slows down, by riding the speed difference of roller and air roll,
Make paper by pulling force in the front-back direction, so that paper be made to disconnect from perforated lines.
Preferably, shiny surface and rough surface, the roll surface of corresponding air roll are intervally distributed on the roll surface of the upper rewind roll
On be also intervally distributed with boss, the shiny surface on the boss on air roll roll surface and upper rewind roll roll surface in correspondence with each other, air roll
The rough surface in other parts and upper rewind roll roll surface on roll surface is in correspondence with each other.
The coreless rolls rewinding paper breaking mechanism of the utility model is simple and reasonable for structure due to the above structure, and break paper
Straight uniform, convenient operation and control.
Detailed description of the invention
Fig. 1 is the horizontal cross-section structure diagram of the utility model embodiment；
Fig. 2 is the positional diagram that the utility model embodiment rides roller 3 Yu air roll 4；
Fig. 3 is structure enlargement diagram at the A of the utility model embodiment.
In figure: 1, upper rewind roll；2, lower rewind roll；3, roller is ridden；4, air roll；5, pressure arm；6, cylinder；40, boss.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Fig. 1~2, the coreless rolls rewinding paper breaking mechanism of the utility model embodiment includes upper rewind roll 1, lower multiple
Winding up roller 2 and roller 3 is ridden, wherein upper rewind roll 1, lower rewind roll 2 and formation rewinding area between 3 three of roller is ridden, in sending for rewinding area
There is the air roll 4 with the cooperation of upper rewind roll 1 in paper direction upstream, and air roll 4 is rotatably connected to 5 end of pressure arm, and pressure arm 5 is another
End is rotatablely connected with cylinder 6, and pressure arm 5 can be rotated with the axis at middle part, by the flexible of cylinder 6, drives air roll 4 mobile.?
During roll paper, when paper roll reaches setting value, riding roller 3 can accelerate, while air roll 4 slows down, by riding roller 3 and air roll 4
Speed difference, make paper by pulling force in the front-back direction, so that paper be made to disconnect from perforated lines.
The coreless rolls rewinding paper breaking mechanism working principle of the utility model embodiment are as follows: paper is in upper rewind roll 1, lower multiple
Winding up roller 2 and roll set under the rewinding area collective effect formed between 3 three of roller is ridden, and constantly increased, and be always positioned in rewinding area
Portion realizes the position that setting paper roll disconnects as needed, in the position punching in advance processing for needing to disconnect, when paper roll reaches setting
When value, riding roller 3 can accelerate, while air roll 4 slows down, and by riding the speed difference of roller 3 Yu air roll 4, makes paper by front and back
To pulling force, since the pulling force that can bear at paper perforating line is minimum, paper can disconnect from perforated lines.
Paper is frayed by the frictional force ridden between roller 3 and air roll 4 when air roll 4 slows down in order to prevent, as shown in figure 3,
It is intervally distributed with shiny surface and rough surface on the roll surface of upper rewind roll 1, is also intervally distributed with boss on the roll surface of corresponding air roll 4
40, the shiny surface on boss 40 and upper 1 roll surface of rewind roll on 4 roll surface of air roll in correspondence with each other, other on 4 roll surface of air roll
Part in correspondence with each other, effectively avoids paper from being rubbed energetically, protects the complete of paper with the rough surface on upper 1 roll surface of rewind roll
Whole property.
For soft paper, common paper breaking mechanism, which relies only on, in the market rides the acceleration of roller 3 to achieve the purpose that disconnected paper, and loose
Soft word bomb is larger, is often not easy to be pulled off, and the coreless rolls rewinding paper breaking mechanism of the utility model effectively overcomes
State problem.
In conclusion the coreless rolls rewinding paper breaking mechanism of the utility model is simple and reasonable for structure, break paper straight uniform,
Convenient operation and control, since principle, structure are simple, installation and maintenance are more convenient.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
Equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, is directly or indirectly transported
Used in other related technical areas, it is also included in the patent protection scope of the utility model.
