At slurries, it includes the closed chamber in negative pressure state to dissipate sizing device 20；First pipe 30, the both ends of first pipe 30 respectively with cut
Device 10, closed chamber connection are cut, it is closed to be delivered to the trimming that cutter device 10 is cut off under the suction function of closed chamber
Intracavitary.
Currently, the rewinding machine speed of high speed is up to 2500m/min, when cutting paper slip speed reaches 2000-2500m/min
When, the design of pressure ranging from 65mbar-75mbar in closed chamber, for example, 65mbar, 61mbar or 75mbar etc..It can be with
Understand, design of pressure it is excessively high, can waste electric energy, and set too low, then suction can be caused insufficient, trimming is caused to get lodged in the
On one pipeline 30, certainly, the pressure value set in closed chamber can be adjusted according to the cutting speed of cutter device 10, be cut
The cutting trimming speed of device 10 is faster, and required negative pressure is bigger, at this point, closed chamber in set pressure value also compared with
Greatly.
In present embodiment, the scattered stock tank that sizing device 20 can be sealed is dissipated.Wherein, the volume range of closed chamber is
20-25 cubic metres, for example, 20 cubic metres, 22 cubic metres or 25 cubic metres etc..
Wherein, first pipe 30 can be closed air hose, the diameter range of air hose in 240-262mm, for example, 240mm,
252mm or 262mm etc..
It is appreciated that the closed chamber dissipated in sizing device 20 is at negative pressure state, in this way, the paper that cutter device 10 is cut
Side under the action of negative pressure can be easy to operate in quick adsorption to closed chamber, and closed chamber is collecting trimming and do not collecting trimming
In the case of belong to closed state, can effective noise reduction function when collecting trimming.
Wherein, trimming collection system 200 includes multiple cutter devices 10 and by multiple cutter devices 10 and scattered sizing device 20
Multiple first pipes 30 of connection dissipate sizing device 20 and are arranged at the middle part of multiple cutter devices 10, so that multiple first pipes
30 length and most short.
In present embodiment, the bad trimming that multiple cutter devices 10 are cut can be fast by corresponding first pipe 30
Speed is sucked into the closed chamber in same scattered sizing device 20, and then is handled trimming, can be reduced occupied by scattered stock tank
Space, and dissipate sizing device 20 and be arranged and can reduce the usage amount of first pipe 30 at the middle part of multiple cutter devices 10, meanwhile, energy
