Labeling machine quality appraisal

labeling machine is mainly used to accurately paste packaging labels onto different containers, making the packaging more standardized and improving the aesthetics and added value of the product. At the same time, the automation features of the labeling machine can improve production efficiency, save labor costs, and ensure the sustainability of the production line.
labeling machine is a machine that can automatically perform labeling operations. It can generally label labels of different specifications and shapes according to the needs of the product. It is widely used in food, cosmetics, medicine, daily chemicals, beverages, electronics and manufacturing industries.
In labeling machine quality appraisal cases, Zhongke Testing can provide labeling machine quality appraisal services.

1, Appearance Inspection
Appearance inspection is an intuitive method to judge the product quality of labeling machine manufacturers. First of all, observe whether the overall design of the labeling machine complies with international standards and industry specifications, and whether the appearance is beautiful and elegant and meets the aesthetic needs of consumers. Secondly, check the printing effect of the labeling machine, including the color, clarity and contrast of the label. Check whether all parts of the labeling machine are tight and not loose. These details can reflect the production level and quality control capabilities of the labeling machine manufacturer.
2, function detection
function detection is a key link in judging the product quality of labeling machine manufacturers. First, check the stability of the labeling machine, that is, whether the equipment can maintain stable operation during the working process without shaking or pauses. Secondly, check the automatic alignment function of the labeling machine, that is, whether the equipment can automatically identify and align the product label without manual intervention. Check the high-precision labeling function of the labeling machine, that is, whether the equipment can complete the labeling process with high precision and whether the label position accuracy meets the requirements. These functional indicators reflect the technical strength and quality control level of labeling machine manufacturers in the R&D and manufacturing processes.
3, performance testing
performance testing is an important step in judging the product quality of labeling machine manufacturers. First, check the speed of the labeling machine, that is, the speed at which the equipment completes the labeling task per unit time. This indicator reflects the performance of the equipment in terms of production efficiency. Secondly, check the accuracy of the labeling machine, that is, whether the position and label accuracy of the equipment when completing the labeling task meet the requirements. This indicator directly affects the quality and market competitiveness of the product. Check the noise of the labeling machine during its working process, that is, whether there will be noise during the operation of the equipment that will affect work efficiency and product quality. This indicator is also one of the important factors in evaluating equipment performance.

The labeling machine purchased by a heavy industry company did not meet the technical requirements stipulated in the agreement. After the installation and trial, the labels attached had a small number of bubbles and warping. After being left for a period of time, the number of labels with bubbles and warping increased. The rate of defective products was high, and a dispute arose with the equipment manufacturer.
was entrusted by the court to conduct an appraisal and analysis on "whether there are quality problems" with the labeling machine involved in the case.
appraisal analysis results: The
appraisal analysis expert group discussed the relevant information and on-site investigation of the labeling machine involved and made a comprehensive quality and technical analysis, and made the following suggestions and conclusions:
1, the initial condition of the labeling machine involved was not abnormal, the basic labeling functions were normal, and the labeling speed basically met the contract requirements, but did not reach the maximum speed agreed in the contract;
2, the labeling machine involved in the case can achieve good appearance quality when used for labeling 120ml bottles, but has poor practicality for labeling 60ml bottles. The labels posted have more bubbles, and the bubble detection rate reaches 11.5%;
3. According to the allowable error of labeling position as agreed in the contract (labeling accuracy: ±1mm), the unqualified rate of position error for 60ml bottles is 10%, and the unqualified rate of position error for 120ml bottles is 8%.
