Various factors that affect the inkjet printer on the bottle cap

In the beer packaging process, there are many factors that affect the packaging efficiency and packaging quality, and it is often difficult to completely solve it from one aspect. For example, bottle cap printing, it involves many aspects such as bottle cap quality, ink quality, printer failure, operator operation, etc. Links need to be quickly eliminated, so as to determine the key influencing factors and prescribe the right medicine. Zhengzhou inkjet printer manufacturers briefly discussed the factors that affect the quality of bottle caps during the production process. 1. Defect analysis 1) Ink code wear and tear. Before the beer is sealed, the code is normal. After the box is sealed, the code on the bottle cap is worn out for inspection, especially the four corners in the box are the most worn. The reason for this phenomenon is mainly related to the equipment adaptability of the carton size, causing excessive friction between the four corners of the carton and the bottle cap. 2) The inkjet code is easy to drop. It is mainly manifested in that it is wiped off by hand after printing. The main reasons for this phenomenon are as follows: A: The surface of the bottle cap contains a lot of paraffin oil, which will float on the surface of the bottle cap after drying, causing ink and paraffin. The oil is not compatible, or the supplier has changed the brand of varnish when making the cap. It should be noted that this problem is often in large batches, and it is likely that this batch of bottle caps has this problem. B: In the capping process in the bottle cap manufacturing process, paraffin oil must be added to the paraffin roller at a certain frequency to prevent scratches on the printing surface of the tinplate and abrasion of the paraffin roller. If the frequency of waxing is too high, it will cause paraffin on the printing surface. Too much, it is easy to cause the surface of the bottle cap to be too oily, that is, the surface of the bottle cap is usually oily, so that the spray code can be easily erased by hand. This problem is often intermittent. In addition, the supplier has changed the paraffin oil brand, and the difference in the quality standards between the paraffin oils can easily cause this phenomenon. C: Machine failure or operator's misoperation: Since the coding machine is automatic ink dispensing, it is possible that the ink surface tension or viscosity is not enough when the ink is mixed due to the machine failure, resulting in insufficient adhesion between the inkjet printer and the bottle cap. If you check that the machine is normal, it may also be caused by the operator's misoperation, which artificially caused the ink surface tension or viscosity to be insufficient, which caused the inkjet quality to be unstable. 3) Blurred handwriting. The bottle cap can only achieve clear and stable coding quality when it is dry and free of oil. Therefore, the general brewery is equipped with a blowing device in front of the coding machine. If the wind pressure is insufficient, the water stains on the bottle cap will not be blown cleanly, or the wind itself will be dirty and oily, which will easily cause the spread of the writing after the coding. If the blowing device is installed in front of the labeling machine, pay attention to whether the contact part of the labeling machine with the bottle cap is clean and free of water stains. 4) Missing, crooked or half-typing. These defects are mainly caused by equipment failures, such as: uneven height of the bottle, a slightly higher bottle will bump the nozzle of the printer, resulting in missed and crooked printing; improper debugging of the printer will cause half-printing, etc. 2. Preventive measures 1) Use the bottle shoulder spray code method. Using bottle wall coding is an effective measure to solve the problem of coding. The coding ink is dissolved in alkaline water, and the date sprayed on the bottle shoulder will not cause friction between the bottles and wear. But it is worth mentioning that the date sprayed on the shoulder of the bottle will give the criminals who make fake wine a good opportunity. We have encountered such cases: the criminals reclaimed the original bottles and cartons with the trademark, and only replaced the bottles. Cover, fill the wine and pretend to be Tsingtao Beer. In this regard, each brewery needs to do work to safeguard the legitimate interests of the enterprise. 2) Add bottle caps to the factory for inspection. Take a few out of each box of bottle caps that enter the factory and do the actual inspection on the inkjet printer, you can effectively understand the adaptability of the bottle caps of this batch, prevent them in advance, and take measures in advance. 3) Refine the procurement standards, and make clear requirements for the adaptability of coding in the supplier's bottle cap procurement standards. Generally, the more formal bottle cap factories have certain requirements on the performance of the varnish when purchasing the varnish, such as: gloss, paint film loss value, high temperature resistance (no explosion at high temperature), surface hardness, etc., beer The company requires the supplier to test its inkjet performance when purchasing the varnish, so that it can effectively cooperate with the supplier to prevent the occurrence of abnormalities. In addition, if there is an irregular or irregular phenomenon that the code is easy to wipe by hand, the supplier should be reminded to reset the frequency of adding paraffin wax to the paraffin roller and pay attention to whether the capping machine is smooth, because if the bottle cap is covered with a little paraffin, it will not Affect the normal capping of the capper. 4) Formulate standard inkjet printer operating procedures, including debugging, maintenance, operation, brushing, etc., so that the inkjet printer is always in a normal state and prevent abnormalities caused by human factors. 5) Suddenly 6 check, check whether the wind pressure is normal, check whether the nozzle is skewed, check whether the machine needs cleaning, etc., and raise the hidden danger of the problem. Summary: A small bottle cap printing problem will cause a decrease in work efficiency and an increase in costs in the packaging workshop. It requires careful observation and timely summary by every technician.
