When you read the newspaper, you should have paid attention to a row of pinholes on the edge of the newspaper, 'It is the trace left when the gripper row on the rotary machine transfers the printed products to the folding mechanism. It plays a vital role. However, the negative effect produced by the gripper cannot be ignored. The waste of paper caused by it is shocking. Taking the 890 rotary printing machine (with gripper) as an example, it takes about 1 hour to start up compared to the rotary printer without gripper. More than 10,000 pieces of white paper strips of 890mm X 10mm are wasted, and about 300,000 pieces of paper are wasted every day. The value of wasted white paper strips in one year is more than 100,000 yuan.
As far as the printing industry is concerned, 10 years ago, the profit was quite considerable, and the investment flexibility was great. Buying a printing machine and making money when you open it. Now, this has become history, and printing has entered a period of meager profit. In the face of this situation, many printing companies have worked hard to save costs. While pursuing benefits, how to reduce resources and energy consumption has become a new idea for the development of enterprises, and it has also become the basis for the survival of enterprises. Some companies start from the bottom up, pay attention to energy conservation, practise conservation, and make a fuss about reducing consumption.
The gripless rotary printing machine developed by Xinglong Printing Machinery Co., Ltd. meets the needs of users.
1. Make a fuss about saving paper
Adopting the non-clamping printing technology to change the cradling needle to drag the paper forward into the folding process, which is the folding method of the skewer roller pushing the paper forward into the guide rail Each paper saves 10mm paper strips and stays directly on the roll paper. When the 890 machine prints 62 newspapers, it saves one blank paper. The 850 machine saves a blank sheet for every 58 newspapers printed. Each machine can save users more than 100,000 yuan per year.
2. Work hard to reduce energy consumption
Multi-stage speed change is adopted to change the torque. Frequency conversion stepless speed regulation, reduce the host motor, to achieve the purpose of power saving. The main motor of the rotary machine without gripper can save about 1/2 of the electric power compared with the traditional rotary printing machine, so as to achieve the purpose of energy saving.
3. Innovate in improving folding quality
Because the machine is equipped with an indentation knife at 180 degrees of the folding machine's drum separation knife, a mark is made in the middle seam of the folding before folding, which can improve the folding accuracy and also help The air between the printing sheets is discharged to make the product more tightly folded.
