Trouble prevention method of automatic flat bed die cutter machine
Papermaking inspection of the pressing part
For automatic flat bed die cutter machine, the detection of paper yield in the press section is very important. Some operators sometimes turn off this detection feature, which is very dangerous. If the paper output test of the paper feeding test in the pressing part is normally closed, once a paper jam occurs in the pressing part, several layers of paper will be superimposed instantly, which will definitely cause a traffic jam accident, cause great damage to the equipment, and it is very difficult to handle the accident .
Precision adjustment of automatic flat bed die cutter machine
The front gauge accuracy of the automatic flat bed die cutter machine is the key parameter to ensure the front gauge accuracy. There are many factors involved in the adjustment of pre-rule accuracy. Some operators usually only use the pre-gauge inspection system. This method is not scientific. Although the front gauge inspection system can avoid problems such as paper misalignment and paper skew caused by unreliable grippers, if the front gauge accuracy is to be adjusted by the system, the probe diameter must be adjusted from about 1 mm to about 0.1 mm alarm accuracy, which is has proven to be impossible. Therefore, factors such as pinch roller, paper feeding time, side gauge pull force, etc. Comprehensive consideration should be given to adjust the precision of the front gauge to the best state.
Regular maintenance of teeth
Periodic maintenance of the tooth row should also be performed. Generally speaking, its common faults are as follows:
1. Insufficient clamping force of the teeth
When processing some coated packaged products, the die-cut deviation of packaged products tends to increase, and the deviation is irregular. This may be due to insufficient bite force of the dental plate. Since the operation of the toothed plate is a process of instantaneous acceleration and deceleration, the surface of the coated packaged product is smooth, and the friction force with the toothed plate during the feeding process is insufficient. If the bite force of the tooth plate is insufficient, the product will inevitably slip during the die-cutting process, which will lead to an increase in die-cutting deviation.
2. The gap return spring is broken or aging
After this failure, the row of teeth cannot accurately and reliably position the sheets and press them together, which will result in a drop in yield. When overhauling the equipment, the staff must pay attention to this part and repair or replace the damaged or aging parts in time to ensure normal production.
Regular oil change
The factory documents of each brand of automatic flat bed die cutter machine have a very strict lubrication periodic table, and there are detailed requirements for the brand and model of lubricating oil required by each part of the equipment, especially the lubricating oil replacement cycle. Generally speaking, enterprises can basically buy lubricating oil according to the brand and model they need, but ignore the regular replacement of lubricating oil. Many equipment lubrication managers see that when the oil change cycle comes, the oil in the equipment tank is still very clear. In order to save costs, they abandoned plans to replace the oil with new oil, allowing the equipment to continue to operate.
Maintenance method of automatic flat bed die cutter machine
1. First of all, the operator should pay attention to dustproof and clean.
In actual production, a large amount of waste paper edges and paper cotton will be produced when the carton is cut. If you don’t pay attention, the chain drive part, the die-cutting part moving platform and some rotating moving parts will enter, as well as the photoelectric detector head and so on. will be blocked, resulting in failure. Therefore, the body of the automatic flat bed die cutter machine must be cleaned first to ensure trouble-free operation of the machine.
2. Second, replace the oil of the die-cutting machine
The main work of the automatic flat bed die cutter machine is to drive the sliding bars and pulleys through the main motor, and then drive four pairs of toggle bars to move, and the high speed can reach 6000 sheets/hour. This is very troublesome without good lubrication and cooling. Lubrication and maintenance are divided into daily maintenance, weekly maintenance and monthly maintenance
3. Maintaining the machine is a must for every operator
Because the machine is not well maintained, this will increase maintenance costs and business expenses. Second, it can cause a lot of damage to the machine, thereby shortening its lifespan.
These three factors affect operations and delay production. Machine failures definitely affect operator mood and delivery deadlines.
