Continuous weighing system for small products and weighing method thereof

A continuous weighing system for small products, comprising a support, wherein the system comprises a feeding mechanism, a conveying and transferring mechanism, a plurality of pushing rods, a pushing mechanism, a plurality of resetting mechanisms, a weighing mechanism, a discharging channel and a linkage follower mechanism, wherein,

• the feeding mechanism is arranged at a top portion of a support, and the feeding mechanism is configured to convey the plurality of small products to the conveying and transferring mechanism in a single row mode;
• the conveying and transferring mechanism is arranged below the feeding mechanism, and the conveying and transferring mechanism is configured to convey the plurality of small products to the weighing mechanism one by one;
• the conveying and transferring mechanism includes a transferring wheel, a plurality of first channels, a plurality of sliding blocks, a plurality of first grooves and a guide base, the transferring wheel is arranged below the feeding mechanism, the plurality of first channels are arranged on an outer circumferential surface of the transferring wheel at an equal interval along an axial direction, the sliding blocks are arranged inside the first channels, the plurality of first grooves are arranged on the outer circumferential surface of the transferring wheel between each two adjacent first channels at an equal interval along an axial direction, the guide base is closely proximate to a part of the outer circumferential surface of the transferring wheel;
• each of the pushing rod is arranged at one end of a respective one of the sliding blocks along an axial direction of the respective one of the sliding blocks;
• the pushing mechanism is arranged on one side of the transferring wheel, and the pushing mechanism and the pushing rods are located at a same side of the transferring wheel, and the pushing mechanism is configured to push the sliding blocks connected with the pushing rods to slide along the first channels in a direction away from the pushing mechanism;
• the resetting mechanisms are configured to push the sliding blocks connected with the pushing rods to slide along the first channels towards an initial position;
• the weighing mechanism is arranged below the transferring wheel and fixed on the support, and the weighing mechanism is configured to weigh the small products one by one;
• the discharging channel is arranged below one side of the weighing mechanism away from the guide base, and the discharging channel is configured to discharge the weighed small products;
• and
• the linkage follower mechanism is arranged above the discharging channel, and the linkage follower mechanism is configured to prevent the small products from slipping from the weighing mechanism to an external environment caused by a function of inertia.
