How to prevent flat bed die cutting machine failure
In daily use, the flat bed die cutting machine may malfunction due to improper operation or irregular maintenance. The following are common faults and maintenance suggestions compiled by Shandong Lukes Mchinery:
1. Paper exit inspection of die cuttingpart
For the flat bed die cutting machine, the paper exit inspection of the die cutting part is very important. Some operators will turn off this inspection function, which is extremely dangerous. If the paper feeding inspection of the die cutting part is normal and the paper exit inspection is turned off If there is a paper jam in the die cutting part, the multi-layer cardboard will be accumulated in an instant, and there will be a stuffy car accident, which will cause great harm to the machinery and equipment, and is likely to cause safety accidents.
2. Precision adjustment of flat bed die cutting machine
The front gauge accuracy of the flat bed die cutting machine is an important main parameter to ensure the accuracy of the front gauge. The adjustment of the front gauge accuracy involves various elements. Some actual operators usually only use the front gauge inspection system software. This kind of method is unreasonable. Although the front gauge inspection system software can prevent the paper type from being untimely and the paper type inclination caused by the unreliable tooth row, but if you want to truly adjust the front gauge accuracy according to the system software, the camera diameter must be adjusted from 1mm up and down to 1mm. The alarm accuracy of 0.1mm up and down, in fact, it cannot be maintained. Therefore, factors such as the platen roller, the paper feeding time, and the tensile force of the side gauge should be fully considered to adjust the precision of the front gauge to the best situation.
3. Repair the teeth on time
The tooth row needs to be repaired on time. Generally, its common faults are mainly as follows:
(1) Insufficient bite force of the toothbrush gripper
In the production and processing of some surface-coated packaged products, the die cutting error of the packaged products is usually enlarged, and the error is not regular. In the whole process of acceleration and deceleration, the surface layer of the coated products is smooth and clean, and the sliding friction with the tooth bar is not enough in the whole process of feeding. The load will cause the die cutting error to expand.
(2) The backlash calibration spring is cracked or brittle
After such common faults occur, the tooth row cannot guarantee the precise and reliable positioning of the gripping paper and the precise positioning of the joint pressure, which will reduce the output rate. Workers must pay attention to this part when repairing machinery and equipment, and repair or replace cracked or brittle components immediately to ensure that everything is properly manufactured.
4. Change the lubricating oil on time
There are very strict lubrication and maintenance tables in the factory documents of the flat bed die cutting machine. There are detailed regulations on the well-known brands, models and specifications that require grease for each part of the machine and equipment, especially the cycle time for grease replacement. In general, the company can basically buy grease according to the prescribed well-known brands and model specifications, but it is careless about the timely replacement of grease.
The maintenance method of the flat bed die cutting machine:
(1) Operators should pay attention to anti-fouling
In the specific manufacturing process, when the carton is die-cut, there will be a lot of waste paper edges and paper wool. If you are not careful, it will enter the die cutting dynamic and static platform parts, and will cover the light point switch detection, resulting in common failures. Therefore, it is necessary to put the confetti cleaning of the die cutting part in the first place, and then it can ensure the normal operation.
(2) Change the oil of the die cutting machine
The flat bed die cutting machine is driven by the main motor to push the sliding bar, the moving pulley, and then the four toggle levers to move. Its high speed operation exceeds 6000h/s, and it is very dangerous if it is not sufficiently lubricated and cooled. Lubrication maintenance is divided into daily maintenance, weekly maintenance and monthly maintenance.
(3) Maintenance of equipment is a job that every operator must ensure on time. Due to imperfect equipment maintenance, it will cause:
Increase maintenance costs and company expenses
There is a greater damage to the equipment, resulting in a reduction in the life of the equipment;
Endanger the actual operation and delay the normal production.
Equipment failure can delay delivery deadlines.
At the level of mechanical equipment, the common common faults of flat bed die cutting machine are the slanting condition of the service platform. This kind of thing often sees dirty things falling into the die cutting part. Generally, the two wedge-shaped parts under the drag shaft should be used. In addition, the platform should be rotated to the upper limit point. At this time, check its relative position to the upper platform to ensure the distance between the four viewing angles of the moving platform and the upper platform (the area where the die cutting board is sandwiched).
The above are the common faults and solutions, common fault prevention and maintenance methods of the flat bed die cutting machine analyzed for you. Hope it can help everyone! It should be understood that at this stage, the technology of flat bed die cutting machines in China already has a high level.
The automatic flat bed die cutting machine is the development trend of the future machinery manufacturing industry, and its key characteristics are reflected in the following two levels: automation and intelligence. The functions of the flat bed die cutting machine are also gradually diversified, which can be die cutting, hot stamping, and holographic projection logos.
