Description

Technical Field

[0001] The utility model relates to the technical field of food additive production equipment, in particular to a quantitative feeding and packaging machine for powder additives. Background Art

[0002] Food additives refer to chemically synthesized or natural substances added to food to improve food quality and color, aroma, and taste, as well as for preservation and processing needs. Common food additives are divided into powdered and liquid forms. There are many types of powdered additives, such as thickeners, emulsifiers, leavening agents, quality improvers, etc. Adding corresponding food additives (powdered additives) to food can improve the quality of food and meet people's demand for food;

[0003] During the packaging process of powder additives, it is usually necessary to weigh the powder additives through a weighing device, and then the staff will pour the weighed powder additives into the hopper in turn, and inject the powder additives into the corresponding packaging bags through the guidance of the hopper, so as to realize the quantitative feeding and packaging of the powder additives;

[0004] When packaging powder additives, although the powder additives can be weighed by the weighing equipment, after the weighing is completed, the staff must load the weighed powder additives into the corresponding packaging bags through the discharge hopper, which is troublesome to operate and reduces the packaging efficiency. Some powder additive quantitative feeding and packaging machines are equipped with weighing equipment inside the storage box. During the work, the powder additives are put in and then weighed. When the weight of the powder additives reaches the set value, the powder additives are stopped. Then, the weighing equipment is driven to rotate by the adjusting equipment. The powder additives pass through the gap between the weighing equipment and the storage box and fall into the bottom of the storage box. The weighed powder additives are finally discharged into the corresponding packaging bag through the discharge pipe, thereby realizing the quantitative feeding and packaging of the powder additives. Although this method improves the packaging efficiency, after the adjusting equipment adjusts the position of the weighing equipment, it is often necessary to add an additional self-locking unit to realize the locking and fixation of the weighing equipment, which leads to a more complicated internal structure of the powder additive quantitative feeding and packaging machine. For this reason, we propose a powder additive quantitative feeding and packaging machine. Utility Model Content
