The material to be weighed passes through multiple collars 2 in sequence. When the distance between the collars 2 at both ends of the material to be weighed is the same, the output shaft of the hydraulic cylinder 12 extends to drive the driving swing arm 801 and the rotating shaft 8 to rotate. The rotating shaft 8 drives another rotating shaft 8 to rotate through the synchronous connecting rod 11. The second swing arm 803 rotates to drive the bracket 5, the load-bearing frame, and the collar 2 to move upward. The collar 2 drives the material to be weighed to move upward until it completely leaves the conveying roller 3. After weighing, the output shaft of the hydraulic steel contracts, the collar 2 moves downward, and the material to be weighed contacts the rotating roller of the conveying roller 3. The rotating roller rotates to transport the material to be weighed to the specified position. Continuous weighing can improve work efficiency. The device is set along the conveying roller 3, occupies a small area, and improves the space utilization rate of the production line.
