Problems solved by technology
The existing feeding device is often unable to adjust the discharge volume of the hopper. If the material given out is too fast and too much, it will cause material accumulation, or the material in some bags will be heavy. If the material is too little, it will cause the material in some bags to less lighter

Description
technical field [0001] The invention relates to an accessory of a food packaging machine, in particular to a belt quantitative feeding device. Background technique [0002] A food packaging machine usually includes a hopper, a feeding device, a filling device and a bag pushing device arranged below the filling device. In order to ensure the consistency of the weight of each packaged product, precise dosing is required. The existing feeding device is often unable to adjust the discharge volume of the hopper. If the material given out is too fast and too much, it will cause material accumulation, or the material in some bags will be heavy. If the material is too little, it will cause the material in some bags to Less is lighter. Contents of the invention [0003] The invention provides a belt quantitative feeding device capable of controlling and adjusting the discharge volume of a hopper. [0004] The scheme is as follows: belt quantitative feeding device, including two ...
