Key 132 rotates, and by the connection of left-cut tool shaft coupling 211, left spline 132 is transferred power on left cut cutter shaft 221, equally
, while right spline housing 135 rotates, right spline 133 is driven to rotate, by the connection of right-cut tool shaft coupling 212, right spline
133 transfer power on right cut cutter shaft 222, left cut cutter shaft 221 and right cut cutter shaft 222 with cutter 23 mounted thereto into
Row rotation, cutter 23 downward when punched on packaging film.
Fig. 5 is the structure chart for detecting electric eye and detecting cam, is provided with original on the servo shaft coupling 12 close to bearing 171
Point returns cam, has a protrusion 1621 on the outer edge of original point return cam 162, in the front of original point return cam 162
It is additionally provided with the first electronic eyes 152 (first detection unit) that can detecte protrusion 1621, when punch powers on, is pressed
The switch of servo motor 111, servo motor 111 drives transmission system that cutter 23 is made to carry out circular-rotation, when original point return cam
162 follow servo shaft coupling 12 to rotate together, when protrusion 1611 goes to nearest with a distance from the first electronic eyes, the detection of the first electronic eyes
To protrusion 1611, generating signal and be sent to the control unit on servo motor 111, control servo motor 111 stops operating one second,
At this moment cutter head is just arranged downward because in punch installation, cutter upside down when, it is convex on original point return cam 162
Rise 1611 nearest from the first electronic eyes 152 (first detection unit) with a distance from, the first electronic eyes 152 can detect the protrusion 1611,
To which the control unit of servo motor 111 receives the signal that the first electronic eyes 152 is sent, control servo motor 111 stops turning
When dynamic, cutter head is just arranged downward.
X-axis direction is also set up on servo shaft coupling 12 with semi-cylindrical hill in the left side of original point return cam 162
Electric motor starting cam 161 also sets up the second electronic eyes 151 (second detection unit) in the front of electric motor starting cam 161, and first
Electronic eyes 152 and the second electronic eyes 151 are each attached on detection electric eye mounting rack 153, and detection electric eye mounting rack 153 is fixed on the
The left side of side plate 521, after cutter head is adjusted to downward, the semi-cylindrical hill of electric motor starting cam 161 is just from the second electricity
Sub- eye is nearest, and the second electronic eyes detects semi-cylindrical hill, generates signal, the control unit being sent on servo motor 111, control
Unit control servo motor 111 processed starts to start, until the second electronic eyes 151 can't detect semi-cylindrical hill, servo motor 111
It stops operating, at this point, packaging film is moving ahead always under the driving of packing machine, servo motor 111 does not exist when stopping operating
It is punched on packaging film, until the second electronic eyes 151 detects again due to inertia half on the electric motor starting cam 161 of rotation
Circular protrusions, servo motor 111 are enabled on packaging film again and punch, until the second electronic eyes 151 (second detection unit)
It can't detect semi-cylindrical hill again, servo motor stopping does not turn, repeatedly in this way, getting the U-shaped hole of spacing on packaging film.
<pitch adjustment mechanism 3>
With reference to Fig. 2, Fig. 3 and Fig. 6, pitch adjustment mechanism 3 be also it is symmetrical about x-axis center line, here also only to side
Structure is introduced comprising is set to the handwheel 31 in 522 outside of the second side plate, fixes across the second side plate 522 with handwheel 31
The wide screw rod 321 of connected dextrorotation tune, is set on right-handed nut 331 right-handed nut 331 cooperated with the wide screw rod 321 of dextrorotation tune
Portion and right sliding block 341 connected therewith, right sliding block 341 along the sliding rail 35 done on the fixation transverse slat 54 to move linearly, adjust wide connection
Axis device 36 passes through the wide screw rod 322 of left-handed tune for adjusting wide shaft coupling 36 to be connected with the wide screw rod 321 of dextrorotation tune and the wide screw rod of left-handed tune
322 match left-handed nut 332, be set to 332 top of left-handed nut and left slider 342 connected therewith, wherein left-handed tune
The other end of wide screw rod 322 is arranged in the bearing on left bearing support 531, left-handed to adjust wide screw rod 322 and the wide screw rod of dextrorotation tune
321 are respectively positioned on the top of left spline housing 134 and right spline housing 135, left-handed to adjust wide screw rod 322 and wide 321 screw thread of screw rod of dextrorotation tune
On the contrary, being provided with a digital display 37 in the left side of handwheel 31, the moving distance of left and right spin nut is shown, thus according to left and right
Distance determines U-shaped hole position between the moving distance of spin nut and the left and right spin nut of former setting；Transverse slat 54 is placed in left bearing branch
The top of seat 531 and right left bearing support 532, between the first side plate 521 and the second side plate 522, both ends and with first
Side plate 521 and the second side plate 522 are connected.
The principle that U-shaped hole pitch adjustment mechanism adjusts x to U-shaped hole spacing is as follows:
Handwheel 31 is rotated, the wide screw rod 321 of dextrorotation tune being connected with handwheel 31 rotates with it, with wide 321 phase of screw rod of dextrorotation tune
The right-handed nut 331 of cooperation moves linearly with right sliding block 341 along sliding rail 35 on the wide screw rod 321 of dextrorotation tune, and dextrorotation tune is wide
Screw rod 321 adjusts wide screw rod 322 by adjusting wide shaft coupling 36 to be connected with left-handed, while the wide screw rod 321 of dextrorotation tune rotates, left-handed tune
Wide screw rod 322 synchronizes rotation, since the wide screw rod 321 of dextrorotation tune is different with the left-handed hand of spiral for adjusting wide screw rod 322, thereon
Left-handed nut 332 and right-handed nut 331 is opposite or the direction supported or opposed moves linearly with left slider 342 along sliding rail 35, it is right
Slitter shaft 222 is arranged in the bearing on right-handed nut 331, and same left cut cutter shaft 221 is also disposed at the axis on left-handed nut 332
In holding, when controlling two cutter relative motions, right-handed nut 331, which pushes right cut cutter shaft 222, makes right spline 133 from right colored part set
135 inner stretchings, left-handed nut 332, which push left cut cutter shaft 221, makes left spline 132 from the 134 inner stretchings of right colored part set；It cuts left and right two
When knife back movement, right-handed nut 331, which pushes right-cut tool shaft coupling 212, makes right spline 133 put in right colored part set 135, is left-handed
Nut 332, which pushes left-cut tool shaft coupling 211, puts in left spline 132 in right colored part set 134.X between two cutters in left and right in this way
The distance in direction just changes, to meet the needs of packaging different length product.
A dextrorotation limited block 3211 is respectively set at the both ends of the wide screw rod 321 of dextrorotation tune, to limit right-handed nut or so
Mobile distance；A left-handed limited block 3221 similarly is respectively set at the left-handed both ends for adjusting wide screw rod 322, it is left-handed to limit
The distance that nut moves left and right.
The revolving speed that the adjustment of Y-direction U-shaped hole spacing needs to adjust y to two servo motors 111 is different, so that it may on packaging film
The U-shaped hole of different spacing is got, for example stamps two U-shaped holes on two sides of the packaging bag of instant noodles.
Above-described driving mechanism 1, perforating mechanism 2 and pitch adjustment mechanism 3 are symmetrical about X-axis center line, above
The structure of one side is only write, the structure of the plane of symmetry is same.
