Corrugated Carton Flexo Printing Slotting Die-cutting Machine Introduction

‌Corrugated carton printer slotter die-cutter with stacker

Carton printing machine is the machine for printing the letters, patterns and informations on the corrugated cartons, it finishes full process via setting plate, inking, printing, delivery cartons to produce finished cartons. Its core units is printer table, anilox roller and feeding part, it covers in packing, logistic and relevant industries.

This machine has flexo printing units, slotting unit, rotary die-cutting unit, it can work only for printing on corrugated cartons, also it can creasing and cutting corrugated cartons, it also can work with folder gluer to be an automatic production line for producing finished corrugated carton productions.it can work with difference thickness corrugated cartons by adjusting rack and power gear, and hot wind suction to make corrugated cardboard plain and straight, it also with ink spray device to implement ink density adjusting and ink baking automatically. Also the machine can high up the precision and stability by Bi directional screw positioning component, shock absorb strip. Maintenance should consider Static maintenance (parts lubrication inspection) and Dynamic maintenance (running state monitor) to extent the machine working life.

Working principal

Before the corrugated carton printer slotter die-cutter working, we have to make a printing plate which with the letter and pattern we will printing on the corrugated cartons, then we fix the printing plate on the machine, then we operate the machine to form ink on the printing plate, then printing the letter and pattern on the cartons, then one by one to copy on cartons.

Printing types and main parameters

Printing machine: maximum feeding size, printing length, printing tolerance, maximum printing width, color quantity, printing speed.

Printing slotting machine: maximum feeding size, maximum printing size, skip feeding size, printing plate thickness, minimum slotting distance, maximum slotting length, maximum speed, maximum corrugated cardboard thickness.

Pre-printing machine: machine speed, printing speed, printing width, material maximum width, material maximum diameter, collection roller maximum width, copy length, printing method, printing plate thickness

Printing slotting die-cutting machine with folder gluer: maximum speed, maximum feeding size, minimum feeding size, maximum skip feeding size, maximum printing size, standard printing plate thickness, minimum folding size, installation size, color quantity.

Printing slotting rotary die-cutting machine: maximum speed, maximum feeding size, minimum feeding size, minimum slotting distance, maximum slotting depth, maximum printing size, standard printing plate thickness, installation size, color quantity.

Machine maintenance

For making sure the corrugated carton printer daily working well, the daily maintenance is essential. The daily maintenance of corrugated carton printer is an important task in the printer management.

Static maintenance

Corrugated carton printing machine static maintenance means we make machine maintenance when we stop the machine.

Establish rules and regulations for machine maintenance.

keep attention on the important parts maintenance

Gear, convex wheel, chain wheel, roller and bearing, these are important parts for the corrugated carton printing machine, we have to keep an eye on these parts maintenance, because the precision of these parts will affect on the printing quality. Spring is the part for keeping force balance on lots of mechanism, it will make sure the running parts precision. The spring has to be with sensitive elasticity, the anelasticity is very bad for the spring working, if we find problems on springs, we have to change a new one.

Technology revolution and strengthen machine maintenance

We have to consider the maintenance when we design the machine for it will be easy for daily maintenance. Because the corrugated carton printing machine is complex, it is impossible to consider all things, and the maintenance point should be difference in difference environment. So we have to try to avoid the bad things of daily maintenance when we design the machine.

Dynamic maintenance

Dynamic maintenance means we make maintenance under the machine running condition. The static maintenance is the premise of dynamic maintenance, and we also can check the static maintenance level by the machine running. The dynamic maintenance is very important.

Corrugated carton printing machine maintenance content:

The machine prepare condition inspection. How about the machine prepare condition, we can check if any thing stuck in the machine? How about the printing plate fixing? If the fixing is not OK, it maybe mak printing plate damage. Check the rubber pad, if it is not OK, also maybe cause the printing fault, and maybe make machine damage.

Lubrication status of the machine. We can check is the oil circuit unobstructed by the oil show device, if there is not any oil here, we have to stop the machine urgently. Check if any oil leak. Though it is simple to find the oil leak, but find the reason is difficult. For the slide bearing machine, low speed is not good for its lubrication. So before we start the machine, it is better to running the machine without material for a while, add the lubricate, this is the first job for every day. Some machine’s oil pump is drove by machine, it is dangerous, some time, the oil circuit can not add lube but suck the lube back to oil box, so we have to check the temperature of the metal, if the temperature is high, then maybe lube system has a problem.

Impact from machine running. The impact little the better for the machine running, and it can extent the machine working life. To reduce the pressure of printing is important for a corrugated carton printing machine working well and stable, on the premise of ensure printing quality, the printing pressure less is better, reduce the machine speed, then its inertia is less, then we can not keep the machine on high speed running for long time.

These are some aspect of corrugated printing machine daily maintenance, the quality of maintenance can react on the quality of printing and machine working life.

The material for corrugated carton printing machine daily maintenance: lube, like Snow oil, chain gear oil, pressure resistant gearbox oil, etc. Clean agents, like clean agents for anilox roller, oil pipe and lube circuit, etc. Anti rust agent, like anti rust lubrication.
