The rejection method of the automatic checkweigher is explained in detail.

Checkweighers can not only accurately measure the weight of products, but also automatically remove unqualified products from the production line through an intelligent rejection system to ensure that every link meets production standards. This article will analyze in detail the main ways of automatic checkweigher and its working principle. First of all, air-blown rejection is a common way of rejection in automatic checkweigher. This method uses high-speed air flow to blow the unqualified product off the conveyor belt. Due to the very fast speed of air-blown rejection, it is particularly suitable for the rejection of lightweight packaged products or fragile products. For example, in the production line of medical gauze or boxed drugs, air-blown rejection can ensure that unqualified products are quickly and accurately rejected, thereby ensuring product quality and production efficiency. Secondly, push rod type rejection is also a common way in automatic checkweigher. It pushes the non-conforming product out of the conveyor belt by pushing the device. The push rod type rejection has the characteristics of moderate speed and accurate rejection, and is suitable for products with moderate weight, such as beer or beverage weighing and sorting. On the production line, push-type elimination can ensure that unqualified products are eliminated in time and avoid the impact on subsequent production. In addition, the lever-type rejection is also an important way of rejection in the automatic checkweigher. It uses two levers to intercept and reject unqualified products from both sides. The speed of the lever type culling is faster, and the culling effect is more significant due to the simultaneous action of both sides. This culling method is usually used in the aquatic product industry, such as the sorting of abalone and sea cucumber, to ensure that only products that meet the standards can enter the next production link. In addition to the above several common rejection methods, the automatic checkweigher has other rejection methods, such as sliding down, swing arm, etc. These culling methods have their own characteristics and can be selected and matched according to the actual needs of the production line. The rejecting method of checkweigher not only affects the production efficiency and product quality, but also directly affects the economic efficiency and market competitiveness of enterprises. Therefore, when choosing an automatic checkweigher, business users should fully consider the characteristics of the product, the needs of the production line, and the applicability of the rejection method to ensure that they choose the most suitable automatic checkweigher. With the continuous progress of science and technology and the continuous improvement of production technology, the elimination method of automatic checkweigher will be constantly updated and optimized. In the future, we can look forward to the emergence of more intelligent, efficient and accurate elimination methods, which will bring greater convenience and benefits to the production of enterprises.


The working principle of weight sorting scale and its multi-application analysis

Weight sorting scales, also known as weight sorting scales, weight sorting machines or weight classifiers, are an indispensable part of modern industrial production lines. It is mainly used for grade sorting, specification sorting and classification of products according to weight range, and is widely used in pharmaceutical, food, chemical and other industries. On the working principle, the weight sorting scale mainly includes three main parts: product buffer section, dynamic weighing section and weight sorting section. First of all, the product buffer section is used to place the product to be tested, and its speed is slightly slower than the latter two sections, which mainly plays a buffering role, so that the product can enter the next stage at a constant speed. Subsequently, the product enters the dynamic weighing section. At this stage, the product realizes dynamic weighing during the belt movement, and the real-time weight data is fed back to the control system. Finally, in the weight sorting section, the control system determines which level of outlet the product should be sorted according to the weight data fed back before, and executes the culling action when the product runs to the corresponding culling port. In practical applications, the use of weight sorting scales is very extensive. First of all, it can choose the sorting method according to the customer's production needs, and sort the products that can be accurately measured, saving labor costs for enterprises and improving production efficiency. In addition, for enterprises with automated production lines, in the product weight detection link, the weight sorting scale can set the standard weight and error range, and automatically reject unqualified products to ensure that only qualified products flow into the next process. In particular, it is worth mentioning that for the natural growth or production of a variety of models, different weights, different sizes of products, such as meat products, medicinal materials, marine aquatic products, hardware accessories, etc., the multi-level sorting function of the weight sorting scale is particularly important. It can be set according to the actual sorting level, help enterprises to achieve accurate weight sorting, and create greater profit space for enterprises. In addition, the weight sorting scale also has a feedback function, which can set the average weight of a certain number of products and feed this information back to the controller of the packaging/filling/canning machine to realize the dynamic adjustment of the feeding amount, so that the average weight of the product is closer to the target value. At the same time, it can also provide a wealth of reporting functions, such as the number of packages per area, the total amount of each area, the number of qualified, the total amount of qualified, the average, the standard deviation and the total number of total cumulative, etc., to provide enterprises with detailed data support. In general, the weight sorting scale provides strong support for modern industrial production with its high efficiency and accuracy. Through in-depth understanding and application of its working principle, enterprises can more accurately control product quality, improve production efficiency, so as to occupy a favorable position in the fierce market competition.
