Description
Technical field
The utility model relates to one and unreels mechanical device, and particularly a kind of nonwoven fabrics cutting machine friction unreels mechanical device.
Background technology
Current: the cutting machine used in China's nonwoven fabrics industry, its main flow is: unreel after yardage roll evenly launches by parts, tension force function unit makes cloth remain tensioning state in the course of the work, tension force is avoided significantly to fluctuate, by cutting parts, cloth is cut into different width again, then the cloth after cutting is rolled into the finished product of all size size that client needs by rolling parts.
In the cutting machine produced at home, the structure unreeling parts mainly contains two kinds: 1) adopt magnetic-powder clutch braking to carry out passively unreeling pattern; 2) motor drag is adopted to carry out initiatively unreeling pattern.Carry out in the passive pattern unreeled in magnetic-powder clutch braking, when cloth coil diameter is larger, the inertia of high-speed operation state lower cloth reel is very large, if need the fault chosen in cloth, when needing to stop, magnetic-powder clutch braking time is long, fault involves in finished product volume already, brings very burden to removing fault.Carry out in the pattern initiatively unreeled at motor drag, unreel and be synchronously difficult to accurate control between motor and winding motor, under fast state, the velocity contrast of several milliseconds can cause cloth to be in relaxed state or by the distortion of drawing, larger tension fluctuation can be caused, rolling finished product degree of tightness is caused to differ, the problem that point section is uneven.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides one and effectively can solve and adopt magnetic-powder clutch braking to carry out passively unreeling and adopt motor drag to carry out initiatively unreeling Problems existing before these two kinds of type orders, during work, can ensure that cloth is in tensioning state all the time, the tension force amplitude of beating is controlled within the certain limit of equipment permission, make the rolling finished product degree of tightness after cutting consistent, section uniform ground, cuts finished product for client produces special quality.
For realizing above-mentioned functions, technical scheme that the utility model adopts is:
A kind of nonwoven fabrics cutting machine friction unreels mechanical device, comprise wallboard conjunction 1, let off roll 2, unreeling shaft 3 and cylinder 6, wallboard conjunction 1 has two, be separately positioned on the left and right sides, let off roll 2 two ends are arranged on wallboard conjunction 1 by bearing seat, yardage roll 4 is around being put on unreeling shaft 3, unreeling shaft 3 two ends are stuck on wallboard conjunction 1 by rolling groove, cylinder 6 has 2, be separately positioned on left and right sidesing wall plate conjunction 1, cylinder 6 is separately installed with slide block 7, slide block 7 is provided with pressure foot 5, pressure foot 5 and unreeling shaft 3 are in same level position, pressure foot 5 can be slided by slide block 7 under the control of cylinder 6, thus realize compressing unreeling shaft 3, yardage roll 4 and let off roll 2 are compressed, keep constant friction force.
Further, in described pressure foot 5 contact with unreeling shaft 3 side be provided with pressurization bearing 8, pressurization bearing 8 pressurization while, together can rotate with unreeling shaft 3, the friction force between pressure foot 5 and unreeling shaft 3 can be reduced like this.
Preferentially, described pressurization bearing 8 has 2, and it is setting up and down, become certain radian, be tangential on unreeling shaft 3, can tightly embrace unreeling shaft 3, such setting, can make two pressurization bearings 8 while compression unreeling shaft 3, together can also rotate with unreeling shaft 3, between such pressure foot 5 and unreeling shaft 3, larger friction force can not be formed, negligible on the impact unreeling process, can prevent unreeling tension force in process beats excessive, causes rolling degree of tightness to differ, the phenomenon generation that point section is uneven.
Further, described unreeling shaft 3 is also provided with rolling groove, and rolling groove is stuck on wallboard conjunction (1), and unreeling shaft (3) can move forward and backward, and yardage roll 4 is placed in lifting of being more convenient for like this.
positive beneficial effect:advantage of the present utility model is 1, work time, can ensure that cloth is in tensioning state all the time, the tension force amplitude of beating be controlled within the certain limit that allows at equipment.2, make the rolling finished product degree of tightness after cutting consistent, section uniform ground, cuts finished product for client produces special quality.3, yardage roll is installed convenient.4, between pressure foot and unreeling shaft, friction force is less, extends machine service life.
Accompanying drawing explanation
Fig. 1 is the utility model scheme of installation;
In figure be: wallboard conjunction 1, let off roll 2, unreeling shaft 3, yardage roll 4, pressure foot 5, cylinder 6, slide block 7, pressurization bearing 8.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
As shown in Figure 1, a kind of nonwoven fabrics cutting machine friction unreels mechanical device, comprise wallboard conjunction 1, let off roll 2, unreeling shaft 3 and cylinder 6, wallboard conjunction 1 has two, be separately positioned on the left and right sides, let off roll 2 two ends are arranged on wallboard conjunction 1 by bearing seat, yardage roll 4 is around being put on unreeling shaft 3, unreeling shaft 3 two ends are stuck on wallboard conjunction 1 by rolling groove, cylinder 6 has 2, be separately positioned on left and right sidesing wall plate conjunction 1, cylinder 6 is separately installed with slide block 7, slide block 7 is provided with pressure foot 5, pressure foot 5 and unreeling shaft 3 are in same level position, pressure foot 5 can be slided by slide block 7 under the control of cylinder 6, thus realize compressing unreeling shaft 3, yardage roll 4 and let off roll 2 are compressed, keep constant friction force.
