  • The label equipment checkweigher is widely used in the express delivery industry, e-commerce companies or other industries that need to paste the code scanning industry: paper boxes, plastic boxes, express boxes, flat paper boxes, paste labels in folders, etc., suitable for checkweigher labels The printer is used to scan and weigh the shipment bar code when sending and receiving shipments in logistics and check the speed.

  • For products you produce or specific types of packaging boxes and documents, our technical product thermal transfer checkweigher can be tailored to your product and process requirements, and can handle your products competently. We have developed a solution to separate your products, then safely transport them to the weighing belt, label them, scan the code and then unload them.

About high-precision automatic weight sorting scale

Automatic weight sorting scale is a new type of Sorting checkweigher of Xinda Company. The weight sorting equipment of check weigher includes belt weighing sorting machine, turntable weighing sorting machine, sliding weight sorting machine and other automatic sorting machines of different structures. . Syndarcheckweighers for sale weight sorting machine can accurately sort the pre-sorted products into specifications/weight grades by weight. The advantage of the weight sorting scale lies in the active control of the filling and batching process.

Grading check weighing realizes weighing to classification according to product attributes, combined system automatic checkweigher meets various production data needs

seafood, laundry detergent, etc., products managed by Automatic weight sorting scale on the production line Weight, sorting weight to prevent defective products from leaving the factory.

About positive and negative static checkweigher

The static weighing equipment for the purpose of sorting is called static checkweigher, and the sorting method: forward rotation and reverse rotation.

Static weighing, because the object is static and stable when weighing on the weighing platform, weighing sampling data is faster than dynamic weighing, so only in terms of weighing, static weighing has higher accuracy than dynamic checkweighers Many, much higher efficiency; static weighing platform has no object moving mechanism, and the cost is very low.

Static weighing equipment, sorting method: forward rotation and reverse rotation to achieve higher speed and more precise selection of products.

  • We design and manufacture a new type of positive and negative static checkweigher to improve accuracy, reduce costs, and save space. The forward and reverse punching work improves the efficiency of punching and improves the sorting efficiency of the checkweigher.

    When working, according to the preset qualified weight interval, the weighing control instrument determines the driving motor to rotate forward or reverse, and rotate (360/N) for each static weighing result on the weighing platform. Then stop and wait for the next weighing result.

  • The loading method of objects on the weighing platform can be manual or automatic. The automatic feeding mechanism includes power belt, bucket type blanking, slide plate that slides down by the gravity of the object, etc.

After years of research, our checkweigher challenge test has been successful. Our technology can guarantee your quality. Our checkweigher equipment is the best monitoring of the various weight standards of different products that your production process depends on.
