The channel T passed through for base stock is formed between 34 and compression bar 35.At work, label tape is placed in the T of channel and connects with compression bar 34
Touching.
Guiding device 33 includes fixed to the guide sleeve 332 on end plate 311 and the guide rod 331 across guide sleeve 332.It leads
Bar 331 passes through elastic device 36, it is preferred that elastic device 36 is spring.Elastic device 36 be placed in compression bar 35 and end plate 311 it
Between, so that elastic device 36 applies a downward power to compression bar 35.Guide rod 331 is secured together with compression bar 35, it is preferred that can
It is bolted and is secured together.By the cooperation of guiding device 33 and the first groove 3121, the second groove 3131, so that
Compression bar 35 can only along the first side plate 312, the second side plate 313 axial movement and will not rotate.
Labelling machine 100 includes limiting device 37.Limiting device 37 include fixed on compression bar 35 pedestal 3722, from pedestal
3722 upwardly extend the first limit plate 3721, upwardly extend from pedestal 3722 and second limit parallel with the first limit plate 3721
Position plate 3723 and cross bar 371.First limit plate 3721, the second limit plate 3723 and pedestal 3722 constitute locating part 372.The
One limit plate 3721 is equipped with the first limiting slot 37211 axially extended, and the second limit plate 3723 is equipped with and axially extends
The second limiting slot 37231.One end of cross bar 371 is placed in the first limiting slot 37211, the other end is placed in the second limiting slot
In 37231.When label tape is placed in the T of channel and label tape is in tensioning state, the first limiting slot 37211 and the second limiting slot
37231 can make compression bar 35 move up and down, to adjust the tensile force of label tape.
Cross bar 371 is set there are two operating position.When cross bar 371 is located at the first operating position L1, compression bar 39 is in fact at this time
Line indicates that label tension adjustment structure 3 does not apply tensile force to label paper.When cross bar 371 is located at the second operating position L2,
Compression bar 39 is represented by dashed line at this time, and label tension adjustment structure 3 applies tensile force to label tape.It, can basis by the setting
It is actually needed and the working condition of flexible setting labelling machine 100.
Preferably, labelling machine 100 includes first driving device 32 and is connected to first driving device 32 and cross bar 371
Connecting rod 38 together.Cross bar 371 can be made to be located at the first operating position L1 or the second operating position by first driving device 32
L2.First driving device 32 can be motor.
With further reference to shown in Fig. 7 to Fig. 8, labeling arm 4 includes floating to label plate 41 and positioned at the labeling plate 41 1 that floats
The fixed labeling plate 42 of side.The bottom surface of floating labeling plate 41 and fixed labeling plate 42 is in the same plane.Float labeling plate 41
Labeling plate 42 can be fixed relatively along the counter motion of fixed labeling 42 moving direction of plate.The labeling arm 4 of the utility model can be with
The stickup of label is carried out to inclined-plane and plane.
The lower section of fixed labeling plate 42 is equipped with the fixation device 44 for fixed labels.Preferably, fixed device 44 is to inhale
Gas nozzle.When needing to grab label, vacuum noz(zle) air-breathing, to fix label.Label labeling arm 4 drive under towards to
Veneer is advanced.When applying labels to after veneer, vacuum noz(zle) stops gas supply, so that label and fixed labeling plate 42 separate
It opens.
Labeling arm 4 further includes the buffing pad 45 set on fixed 42 top of labeling plate.By the way that buffing pad 45 is arranged, can keep away
Exempt from labeling arm 4 with when veneer contacts, because power is excessive will be to veneer compressive strain.Buffing pad 45 can be the dress with spring
It sets.
It floats and is equipped with gap between labeling plate 41 and fixed labeling plate 42.By the way that gap is arranged, can reduce between the two
Frictional force.
Labeling arm 4 further include fixed plate 461 and can the elastic component 462 that moves up and down of opposing fixed plate 461, elastic component
462 lower end is supported in the upper surface for floating labeling plate 41.The setting can make floating labeling plate 41 contact with to veneer
When, the relatively fixed labeling plate 42 of the labeling plate 41 that floats moves up.It is separate when veneer direction is mobile when labelling arm 4, in bullet
Property part 462 elastic force under the action of, the relatively fixed labeling plate 42 of the labeling plate 41 that floats moves down, until the labeling plate 41 that floats
Bottom surface and fixed labeling plate 42 bottom surface it is in the same plane.Air supply pipe 43 is for supplying.
Labelling arm 4 further includes blowning installation 7.Blowning installation 7 is located at the lower section of fixed labeling plate 42.When work, label
It is placed in the centre of blowning installation 7 and fixed labeling plate 42.When label is separated with base stock, label under gravity can be downward
It is mobile.Blowning installation 7 blows (see Fig. 3) to label in lower section, and label is avoided to move down, right convenient for fixed labeling plate 42 in this way
The absorption of label.
Preferably, float labeling plate 41 and fixed labeling plate 42 bottom surface with fix that label the moving direction of plate 42 vertical.
With further reference to shown in Fig. 9 to Figure 11.Part 8 to be measured to veneer include the first plane 81, the second plane 83 and
The inclined-plane 82 that first plane 81 and the second plane 83 are connected.In the position of fixed device 44, label 61 is fixed to
The lower section of fixed labeling plate 42.Arm 4 is labelled towards to veneer movement.Label 61 includes being set to float to label plate 41 and fix
Label the first segment 612 of 42 lower section of plate and the second segment 611 positioned at float labeling plate 41 and fixed 42 outside of labeling plate.
When the label for 41 lower section of labeling plate of floating and first surface 81 contact, the labeling plate 41 that floats is supported by first surface 81
It handles, so that the labeling plate 41 that floats can not continue to travel downwardly.Label be placed in first surface 81 and float labeling plate 41 it
Between.
Arm 4 is labelled to continue towards mobile to veneer.Fixed labeling plate 42 continues to move down, until fixed labeling plate 42
The label of lower section is contacted with the second plane 83.So that label pastes in the second plane 83.Due to 44 pairs of marks of fixed device
The fixed force of label 61 is larger, and smaller to the resistance of label 61 between labeling plate 41 and the first plane 81 positioned at floating, so
When fixed labeling plate 42 moves down, a part of second segment 611 can be mobile towards inclined-plane 82, i.e., second segment 611 can shorten
(this feature can be clearly seen that from the comparison of Figure 10 and Figure 11).Final label 61 can be attached on inclined-plane 82.When label 61 is solid
After setting, fixed device 44 removes the fixed force of label 61.Arm 4 is labelled far to veneer movement, prepares next labeling
Movement.
Although the utility model is that label 61 is pressed onto the first plane 81 between the labeling plate 41 that floats.The technology of this field
Personnel are also, it is understood that if it is also feasible that label 61, which is pressed onto inclined-plane 82, between the labeling plate 41 that floats.
Those skilled in the art can be obvious, can the above exemplary embodiments of the utility model be carry out various modifications and be become
Spirit and scope of the type without departing from the utility model.Accordingly, it is intended to which the utility model covering is made to fall in the appended claims
And its modifications and variations to the utility model within the scope of equivalent arrangements.
