Abstract

A direct connected double drive crosscut machine comprises a driving motor, a main knife roller and a subordinate knife roller. The synchronous transmission gear wheels which are connected on both ends of the main knife roller are mutually engaged with the synchronous transmission gear wheels which are connected on both ends of the subordinate knife roller. The driving motor is an alternating current synchronous servo motor; the driving main motor and the driving subordinate motor are the same, which are directly connected with both ends of the main knife roller separately. The crosscut machine has the advantages of synchronous input of driving power, safe application, high efficiency low production and maintenance cost and evenly distributed torsion on the knife roller. The crosscut machine can be used for high speed crosscut.

Description

The two drive-type transverse cutting units of direct connection

Technical field

The utility model belongs to the cut-out equipment of thin plate processing, the two drive-type transverse cutting units of a kind of specifically direct connection.

Background technology

Existing main frame adopts the transverse cutting unit of brush direct current motor, has spark during use and produces, and has disaster hidden-trouble in Combustible Place such as paper product processing, and the brush of direct current generator need often safeguard, otherwise motor is impaired; Adopt the transverse cutting unit of AC induction motor because there is slippage in asynchronous machine, and output characteristics is softer, and dynamic responding speed is not suitable for the high-speed crosscutting machine, the exciting current of asynchronous machine is bigger simultaneously, and power factor is reduced, and efficient is not high; In addition, prior art mostly is to connect the non-associated mode transverse cutting unit of rotor by motor shaft again by the multi-stage gear transmission, and gear drive reduces mechanical efficiency, and therefore transverse cutting unit has increased production and maintenance cost to the requirement height of travelling gear precision; Particularly single motor-driven transverse cutting unit only connects motor at rotor one end, and power imports into from a side, makes the torsion skewness on the elongated spiral rotor, and when high-speed crosscutting, rotor damages easily.

Summary of the invention

At the above-mentioned technical disadvantages of existing transverse cutting unit, the utility model provide a kind of safe in utilization, efficient is high, production and maintenance cost is relatively low, torsion is evenly distributed, be suitable for the two drive-type transverse cutting units of direct connection of high-speed cutting.

The foregoing invention purpose is realized by following technical scheme: the two drive-type transverse cutting units of a kind of direct connection, comprise drive motors, operator roller 5 and from rotor 6, be connected operator roller 5 and intermeshing synchronous transmission gear 3,4 from rotor 6 two ends, described drive motors is the AC synchronous servomotor, the main motor of identical driving 1 and drive from motor 2 respectively with the two ends direct connection of operator roller 5.

The AC synchronous servomotor is safe in utilization, efficient is high, production and maintenance cost are relatively low, and operator roller 5 both sides are imported power simultaneously and are suitable for cutting at a high speed.

Main motor 1 connects main servo driver of motor 7, connect from servo driver of motor 8 from motor 2, gather the encoder 9 that drives main motor 1 movable information and connect main servo driver of motor 7, gather the encoder 10 that drives from motor 2 movable informations and connect from servo driver of motor 8.

Main servo driver of motor 7, connect programmable computer controller 11 respectively from servo driver of motor 8.

Programmable computer controller 11 connects control computer host computer 12.

Programmable computer controller 11 is Bei Jialai PPC programmable computer controllers.

Master and slave servo driver of

motor

7,8 adopts the ACOPOS drive system.

Encoder

9,10 is installed in main motor 1 respectively and from motor 2.

Operator roller 5 and screw blade 13 is housed from rotor 6.

The utility model has the advantages that: two identical AC synchronous servomotor direct connections are imported power simultaneously at operator roller two ends, and are safe in utilization, efficient is high, production and maintenance cost are relatively low, and the torsion on the rotor is evenly distributed, and can be used for high-speed crosscutting.

The specific embodiment

Two servo main motors 1 of identical AC synchronous in the accompanying drawing, from motor 2 respectively by shaft coupling with the operator roller 5 two ends, left and right sides direct connection, have the operator roller 5 of screw blade 13 and respectively have synchronous transmission gear 3 and 4 to be meshing with each other from rotor 6 two ends, main motor 1 connects the main servo driver of motor 7 that adopts the ACOPOS drive system, from motor 2 connect adopt the ACOPOS drive systems from servo driver of motor 8, Bei Jialai

absolute encoder

9,10 are installed in main servo motor 1 respectively and from servomotor 2, encoder 9 connects main servo driver of motor 7, encoder 10 connects from servo driver of motor 8, main, from servo driver of

motor

7,8 connect Bei Jialai PPC programmable computer controller 11 respectively, and programmable computer controller 11 connects industrial control computer host computer 12.

Slave computer Bei Jialai PPC programmable computer controller 11 is hung the Powerlink bus, and the master and slave servo driver of

motor

7,8 of same model adopts the ACOPOS drive system, respectively carries the Powerlink bus unit, and bus unit connects bus.Main servo driver of motor 7 is arranged to have the motion controller of electric cam function, is arranged to 1 from the electronic gear ratio of servo driver of motor 8, promptly is arranged to the location following device.

Industrial control computer host computer 12 assigns cutoff length to PCC, and PCC reaches the length compensation amount of electric cam the ACOPOS system of main servo driver of motor 7 again, just cuts.By the Powerlink bus positional information is passed to ACOPOS system from servo driver of motor 8, main servo driver of motor 7 with keep synchronously from servo driver of motor 8, thereby two servo master and

slave motors

1,2 of AC synchronous have kept synchronous.The electricity consumption submode is realized coordinate synchronization between the mechanical movement axle, and precision is higher, and dynamic property is better, does not have mechanical loss, makes maintenance become convenient and simple.
