1. Features of the machine:

Main Features:

1. The Bobst type cut structure makes the cutting platform movement like a scissor, it will realize a full and easier cut.
2. 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.
3. The main chains adopt imported British Renold brand, the differences of 10 chains are less than 0.2mm.
4. The connect between gear box and driving shaft adopts sleeve and pin structure ensuring a strong connection.
   1. Speed:  

The machine adopts frequency controller to achieve stepless speed acceleration which can reach to 4500 times per hour. During actual production, it can generally run at 3800 to 4000 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 4200 times per hours without feeling too hard.

1. Safety:

As it is shown in the picture of the machine, the machine adopts rear part 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.

1. 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.

1. Main Structures and Key Material Used
   1. Four Main Big Parts:

They are referring to: 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.

1. 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.

1. 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 semi-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.  

1. 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.

1. Electric Part

The electrical parts are designed and assembled according to the European CE standard and uses world wide known brand products.

1. 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.

1. Special Characters of Our Machine:
   1. 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.

1. Optional Delivery Platform:

According to the requirement of the client we can do the delivery platform either square type or E type (as shown in the picture) . If the client has enough pallets, he can choose square type. If the client does have enough pallet, he can choose, E type platform for which will also provide 4 delivery trolleys.                   

1. Pneumatic Pre-loading and Lifting Step Unit:

The pre-loading device is pneumatic driven. When one paper size is set, when you do other pile of pre-loading, there is no bother of you to reset the pre-loading device, you can just press the button and the machine will do for you.
The lifting step unit is also pneumatic to facilitate the conveying of the paper pile.

1. Dancing Roller Feeding:

Quite some of the die-cutting machine producers use direct feeding method which is the operator will feed the board directly to the mouth of the gripper. What we have found that the feeding time to the gripper is only 0.3 seconds which makes the board feeding work hard and inaccurate.
Our machine uses an additional dance roller feeding system whose board feeding time can be extend to 0.6 second. Together with the conveying parts it makes an easier work of the operator and faster in efficiency of the machine.
For example: If an operator operates the direct feeding semi-automatic die-cutting machine at 3300 sheets per hour, he can easily operate our machine at 3700 – 4000 sheets per hour.                             

1. Conveying Part:

The board received by the dance roller will go through a conveying part with belt conveying and belt pressing which makes the board being pressed before reaching to the front lay.
Before the board reaches to the front lay, he will be repositioned by the side lay.
By these ways, the board conveyed by the dance roller will be more accurate and stable when they reach to the gripper bar.
There is also detector to detect the status of the board. If board does not come to the front lay at normal position, the detector will send signals to stop the machine.

1. None-stop Feeding and Delivery

This type of machine has our patented system – non-stop feeding and delivery functions which can reduce the wor ept stress of the operator and increase the wor ept efficiency of the machine
Under this system, the pre-piling is at the side of the operator. The pre-piled board can be transported under the main pile when the main pile is detected short of paper.
At the delivery part, when the board is cut to be about 1 meter, the machine will push the die-cut board pile out of the machine delivery part so that it is easy for the operator to draw them to the designated place without the need of stopping the machine.
