rotary die cutting machine process steps

Rotary die cutting machine is to achieve the purpose of die cutting through the extrusion of the blade and the bottom roller. According to the production requirements can be designed into different stations (that is, the number of driving wheels), usually according to the station can be divided into 3 stations to 36 stations of the circular knife die cutting machine.

In die cutting production, there will be different requirements for the depth of die cutting of materials, and under normal circumstances, we call it full cutting of materials. Die cut the material to the last layer (generally the material belt is also called the bottom paper), that is, the last layer is not cut off, we call it half cut. There is a height difference between the blade and the shoulder iron, which is the maximum cutting depth. So in our process of using the round knife machine, what are the main links?

1. Feed

It's material on the machine. Put the material into the machine according to the process description, and then put the input and output pressing shafts back in place respectively. The output pressing shafts need to be reinforced to ensure that the force of the output pressing shafts is greater than that of the input pressing shafts.

Whether the material can be straight on the machine accurately and quickly affects the machine adjustment and production efficiency to a great extent. When feeding, the material should generally be placed in a correct position, and then the material should have a certain tension, that is, the tension point will naturally go right, and the joint should be connected when refuelling. To ensure smooth passage of the joint.

2. Put the knife

Wrap the rotary with foam according to the process requirements, and install the circular knife in turn according to the process requirements. When taking and placing the circular knife, the circular knife protection cloth should be added to prevent damage to the circular knife.

3, alignment debugging

For more than one circular knife processing products to carry out several knife alignment. The counterpoint dimensions have two directions namely the transverse dimension and the longitudinal dimension. The longitudinal size is controlled by the knob on the cutter sleeve, which is generally locked after adjustment, and the change is small; The lateral dimensions change a little bit more. Round knives to be matched will be marked with counterpoint, usually two knives are designed as two right angles "┍" "┙", and finally form a "cross".

For more than two knives, different engineers will have different designs, the following is one of the methods, as shown in the picture of four knives:

This method can see the final synthesis effect c, and can monitor the effect of a and b, and can also be convenient for debugging one by one.

Usually we will choose one as the benchmark, that is, the main knife does not need to be adjusted, and the other knives are adjusted relative to the main knife. Choose the main knife according to the actual situation, based on the convenience of alignment.

4. Set parameters

Rotary die cutting machine is a kind of automatic die cutting equipment, in use, the parameter designer is a very important link, according to the process requirements and product needs, set the parameters required for product production, the machine runs according to the parameters set to achieve the purpose of full automation of production.

5. Waste disposal

It is to take away the waste in the die cutting production, and the waste removal is the key and difficult point in the process of the rcircular knife die cutting machine. In the long-term practice of production, a variety of methods have been produced, according to different situations, the use of different methods, and finally realize the automatic discharge of waste into volumes, saving waste labor costs.
