. Features of the machine:
- The Bobst type cut structure makes the cutting platform movement like a scissor, it will realize a full and easier cut.
- Main worm gear uses alloy copper material, after the experienced operator’s manual scraping treatment and strict standard testing, it can ensures the driving parts 10 years life.
- The main chains adopt imported British Renold brand, the differences of 10 chains are less than 0.2mm.
- The connect between gear box and driving shaft adopts sleeve and pin structure ensuring a strong connection.
The machine adopts frequency controller to achieve stepless speed acceleration which can reach to 5000 times per hour. During actual production, it can generally run at 3600 to 4200 times per hour according to the quality of the board. If the quality of the paper is good, a good operator even can operate the machine at highest speed.
As it is shown in the picture of the machine, the machine adopts automatic paper feeding method which keeps the operator away from the die-cutting part. The mounting and adjustment of the die plate is also done outside of the die-cutting part with sensors and detectors at die-cutting part to ensure that the machine can not be started when the die-cutting plate is at adjustment status.
Besides the sensors at die-cutting part, there are sensor or approach switches at window part to make the whole machine at monitoring status to ensure its safety.
- Operation convenience:
There is Man-machine interface installed in the control panel which will shows the safety status of the machine as well as malfunctions to facilitate the operator. Camera is also installed in front of the operator for him/her to monitor the operation status at the delivery part.
- Main Structures and Key Material Used
- Four Main Big Parts:
They are: bottom station, moving platform, upper platform and machine wall. The bottom station is made of gray cast iron -HT 200; the moving platform is ductile iron – QT 42-10 and the machine wall is high quality A3 steel.
- Main Drive:
The 11 KW Siemens Motor together with the pneumatic clutch, worm shaft and worm gear forms a moving set to ensure stable pressure out put of not less than 300 tons.
The material for the worm shaft is 40Cr with quenching treatment and gear hardness HRC 45-50. the material for the worm is copper alloy – ZQAL9-4.
The bearing that is used is SKF. The bush is copper alloy ZQSn6-6-3.
- Die-cutting and Creasing Part:
The drive is transferred via crank rod to pendulum which will bring the moving platform to move up and down to reach die-cut and creasing purpose.
The pendulum is made of high quality ductile iron. The pendulum axis is done by induction harden with surface hardness HRC 43-48. The width of the pendulum is 250mm and diameter of pendulum shaft 70 mm – completely follow the specification of 1080 type automatic die-cutting and creasing machine. Compared with automatic die-cutting and creasing machine which is used for cardboard die-cutting, this type of automatic die-cutting and creasing machine is mainly used for corrugated board which needs less pressure for die-cutting, in this case quite some producers have made smaller width on the pendulum and smaller diameter on the pendulum shaft. We keep wider pendulum and bigger diameter on its shaft to make our machine last for a longer life.
The die-cutting plate uses 7 mm 75 Crl plate which has more hardness and life span than the manganese plate.
- Board Conveying:
It adopts 3-cam intermittent positioning device to ensure the boarding conveying accurate and stable.
The machine uses gripper bar type with 12A long joints chain which is less in weight and less shock to the intermittent device under the precondition to ensure the strength of the chain. The brand of the chain is Renold U.K with high precise and quality. .
The Gripper bar adopts aviation aluminum with three bridge type- light in weight and high in strength.
- Electric Part
The electrical parts are designed and assembled according to the European CE standard and uses world wide known brand products.
- Installation of Die
The die mounting and dismounting adopts side withdrawing ways which time saving and easy for operation.
There are two ways for the fixation of the die-either by bolt or clippers which are subject to customer’s advice.
The chase loc ept is pneumatic which is simple, convenient and reliable.
- Special Characters of Our Machine:
- Clever And Special Front Lay Design:
Compared with the card board sheet, the corrugated board has more strength. If the corrugated board abnormally reaches to the front lay, it will damage the front lay and the gripper bar when the front lay reaches to its highest position.
Generally the producers will install sensors on this part to stop the machine when the paper is fed abnormally to the front lay. However, when the machine is running at the high speed, the inertia will bring the machine to run for a while to make the front lay to its highest point and then also damage the front lay and the gripper bar.
Our special design is that when the abnormal board feeding happens and being detected, the front lay can never reaches to its highest point which makes free from front lay and gripper bar damages because of abnormal paper feeding.
As it is our special design, so there is no picture to be shown here.
- Auto-Manual Switching System
The Feeding system for this type of machine can do auto and manual. When the sheet shape is good, you can use auto-function. When the shape of the sheet is not good, you can use manual function and do sheet feeding manually.
When the sheet is not good in shape,, you can open the rear beam and lift up the feeder to do manual feeding.
