Collection quickly through paper web image information high speed CCD camera 2, be provided with alarm 3 on the inside of camera mount 1, be located at height
It is provided with crossbeam immediately below fast CCD camera 2, direct light source 6 is provided on crossbeam；
It is provided with scanning support 7 on the right side of camera mount 1, is provided on scanning support 7 for cleaning the soft of paper surface
Property band 8 is provided with mark zone 9 on the crossbearer of scanning support 7；
The left side of camera mount 1 is placed with paper winder, and paper winder includes that will test into the bundled roll paper of paper roll
Axis 10, winding shaft 10 are engaged across 11 connection gear 13 of bearing, and gear 13 and belt wheel 1 connect with belt wheel 2 17 again through belt 16
Connect motor 12.
Switch button 1 and switch button 25, the switch button 1 are provided on the inside of the camera mount 1
For shutting down alarm 3 manually.
The direct light source 6 and high speed CCD camera 2 is in the same plane；The switch button 25 can be manual
Control the light on and off of direct light source 6.
8 length of flexible strip is identical as the height of 7 upper end window of scanning support；The mark zone 9 can detect
It is marked rapidly behind to the region for having paper defects.
The winding shaft 10 and gear 13 is with V tooth engagement；Winding shaft 10 is mounted on the two sides of bracket 14, and two sides are solid
Surely there is bearing 11；The 11 model SKF NU1006 of bearing；The motor 12 is to adjust motor, adjusts the frequency conversion of electric machine frequency
Device selects ABB frequency converter A CS150.
The utility model has the beneficial effects that
The utility model has fault alarm, reduces paper web shake, can make a mark rapidly after finding paper defects, improves
The quality of paper improves production efficiency, reduces cost of labor.
Detailed description of the invention
Fig. 1 is the device structural map of the utility model.
Fig. 2 is that the utility model gear engages simple diagram.
Fig. 3 is the utility model gear engagement system.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of paper defect testing device includes two high speed CCD cameras 2, it is mounted on fixed camera mount
1, for acquire quickly through paper web image information, alarm 3 is mounted on the inside of fixed camera mount 1, works as equipment
When operating is abnormal, alarm lamp will be lighted rapidly, remind staff to check equipment fault reason, and switch button 1 can
Alarm device 3 is turned off manually；The direct light source 6 uses LED light, is mounted on the crossbearer of fixed camera mount 1, is located at high speed
The vertical lower of CCD camera 2, highlights；Switch button 25 is mounted on 1 inside of fixing camera bracket, can switch
LED light, the length of LED light should be greater than the length of paper web, identical as the crossbearer length of camera mount 1.
Scanning support 7 is close to fixed camera mount 1, and is placed on the right side of camera support, and flexible strip 8 is mounted on scanning support
On 7, for cleaning paper surface, it in addition can also prevent mosquito from falling on paper web, influence testing result；Mark zone 9, which is located at, to be swept
On the crossbearer for retouching frame 7, connection web inspection system can be stamped at paper defects rear rapidly when detection system detects paper defects
Identification orientation can be provided for subsequent processing with the label of machine recognition.
Winding shaft 10 will test bundled at paper roll, and bearing 11 is fixed in the card slot of bracket, and winding shaft 10 passes through axis
