After the financial turmoil in 2009, many industries were reorganized. Therefore, this issue was only discussed after in-depth thinking. I also invite you to make your own opinions after reading, so that our industry can provide customers with the services they need.
1. The history of the paper laminating machine
This refers to three types of hand laminating machines, semi-automatic laminating machines, and fully automatic laminating machines currently on the market.
This paragraph only mentions the fully automatic laminating machine (post-chain positioning). The earliest automatic laminating machine I repaired was produced in Taiwan in 1984, which is 25 years away! Compared with the structure produced in 1984, the automatic paper laminating machine on the market is not much improved, except that the transmission of the chain is changed to a synchronous belt, and the delivery of corrugated paper is changed to a wide-width suction punching belt, but Positioning is still the position of the chain, it is a long-life model!
The other is a high-speed paper laminating machine with a completely different structure from the above. Since I have not been in contact with this machine, I am not familiar with it, so I would not comment, but my colleagues mentioned that the design speed of this machine is 6000 sheets / hour The actual production speed is about 4000 sheets / hour, but the quality of corrugated paper is relatively required, otherwise there will be some problems in operation. If a friend familiar with this model sees this article, please also tell us the actual situation.
As for the paper-laminating machine made in Europe, please also talk to familiar friends!
Second, the common problems of paper laminating machine
Speaking of which, it comes down to a few points
1. Laminating accuracy: This is also related to the paper itself, but the main problem is still the mechanical structure. New machine or repair, a period of time will appear abnormal fitting accuracy. This problem mainly has the following:
A. The positioning chain is worn (lengthened).
B. The positioning claw is worn (refers to the base of the chain).
C. The positioning sprocket active sprocket has worn out.
Of course, there are other factors that cause operational wear, such as: wear of glue wheel bearings, excessive gear clearance of the four wheel sets, etc. All of these have brought trouble to the operators and the die cutting department at the rear stage.
2. Degumming and staining: when there is more glue, fly the glue and then dip the flowers. There are two aspects: the nature and concentration of the glue, the wear of the glue wheel and the scraper wheel, or the cleaning of the balance gap between the water wheel and the glue wheel, and the wear of the bearing or shaft head.
3. Feida paper output: In this case, two or more sheets of paper are output. This problem is mostly caused by the vacuum gang being worn out, which results in insufficient blowing pressure and insufficient flow.
4. Corrugated paper output: in this case, the paper output belt is thinned, the friction force is reduced, the high-pressure blower is not strong enough, etc.
5. Production speed: The general speed is mostly around 3000 sheets / hour.
The problems mentioned above are common, because there are too many problems caused by wear and tear, so they cannot be detailed in order.
