Design and Application of Checkweigher for Cosmetic Products
Weight check scales, also known as weight check scales, sorting scales, weight sorting scales, check scales, sorting scales, can change the quality of pre-packaged discrete loads (items) based on their mass and nominal set points. The difference is divided into two or more categories, which is a high-speed, high-precision online weight detection automation equipment. The weighing scale is integrated with various packaging production lines and conveying systems, which can detect substandard products in the production line and whether there are missing parts in the packaging in real time. Weighing scales are widely used for automatic weighing testing of production lines in the pharmaceutical, food, chemical, beverage, plastic, rubber and other industries. This is also an essential link in the production process of food, medicine and other industries. In order to protect the legitimate rights and interests of consumers, producers, and sellers, in accordance with the 'Measurement Law of the People's Republic of ChinaAccurately reflect the actual net content on the label, and the difference between the net content on the label and the actual content shall not exceed the specified allowable shortage. Product weight inspection is linked to re-inspection during production, and the weight of the product will be unqualified to ensure that the weight of the product meets the requirements of the factory, which is conducive to protecting the interests of consumers and consumers. Manufacturers, consumers will not suffer losses due to quality, and manufacturers will not suffer losses due to customer complaints or even complaints and reputation damage. Existing weight sorting equipment can be divided into online testing and offline testing. Online testing includes continuous and intermittent testing, while offline testing is usually intermittent testing. On-line continuous inspection usually adopts conveyor mode, which is integrated with medium and high-speed production lines. Check the weight scale online, including feed conveyor, weighing conveyor and unloading conveyor. According to the speed of the production line, determine the feed conveyor speed and other parameters according to the number of products, the length of the product and the length of the weighing conveyor, and make the production line products. Ensure that the weighing conveyor only weighs the products, and at the same time, reduce the time for products to enter and exit the weighing conveyor as before and after the speed of the weighing conveyor. For relatively large long diameter, thinner cylindrical products or short cylindrical products, because they are easy to roll during the conveying process, and the weight of the product is light, the passing state of the product is unstable, the weighing product has an impact, and the measurement result is inaccurate. Especially cosmetics (such as eyebrow pencils, lipsticks, etc.), which are small in diameter, long and thin, can only be transported along the length direction. The weighing conveyor is used for weighing. The transport process is easy to roll, poor stability, and has a great impact on weighing. . In order to overcome the shortcomings of the existing technology, aiming at the problem of small diameter and long slenderness of cosmetics, it cooperated with Shanghai Genyuan Cosmetics Co., Ltd. to install an online inspection scale on the cosmetics production line, adopting V-groove plate and dynamic weighing technology to prevent the product from rolling , Maintain the stability of the product delivery process, realize online weighing, high-speed dynamic stability, and ensure the accuracy of product online weighing. The online cosmetic scale developed has been put into use.
