How to choose a suitable rejection method when purchasing a checkweigher?

First, let's understand the main rejection methods of automatic checkweighers: Common rejection methods of automatic checkweighers include air blowing type, lever type, flap type, push plate type, falling type and shunting type.

1. Air blowing type: Compared with other rejection methods, it has a very fast speed and is suitable for lighter or fragile products, such as medical gauze, boxed packaged drugs, etc.

2. Lever type: Its speed ranks second. The advantage is that products can be rejected from both sides. It is generally used in the aquatic product industry, such as the sorting of abalone and sea cucumbers.

3. Push rod type: The speed is medium. It is suitable for rejecting products with missing bottles or parts in packaging boxes and other products of moderate weight, such as the weighing and sorting of cases of beer and beverages.

4. Flap type: The speed is medium. It is generally suitable for products in the fruit and vegetable industry, such as the online weighing and sorting of single vegetables and single fruits.

5. Falling type: The speed is relatively high. It is generally suitable for washing and daily chemical products.

6. Shunting type: It is suitable for the sorting of bottled products. Using the shunting method can ensure that the bottle does not fall over and the products in the bottle do not fall out. It is more suitable for detecting products without caps.
