Description

TECHNICAL FIELD

[0001] The utility model relates to filling device technical field, especially in automatic packaging is with quantitative filling device. BACKGROUND

[0002] In the tea processing and packaging industry, automatic quantitative filling is a key link to ensure product standardization and improve production efficiency. It is necessary to accurately fill strip-shaped tea into packaging bags according to the preset weight, taking into account the quantitative accuracy and tea quality. With the increasing demand for "intact shape and no broken pieces" of tea in the consumer market, the low damage of automatic filling equipment has become a core competitiveness.

[0003] However, the existing quantitative filling device for automatic packaging still has obvious deficiencies when processing strip-shaped tea and other fragile materials. According to the search, the "tea dregs filling machine device" (application date: January 24, 2011) with publication number CN102092500A uses a screw conveyor as the main feeding structure, which pushes the material from the dregs tank to the discharge port through the spiral blade, and cooperates with the electronic scale for quantitative control. Although this scheme realizes automatic bagging and cooling functions, its core feeding method relies on the close cooperation between the spiral blade and the inner wall of the material bin. During the pushing process, strip-shaped materials (such as tea dregs or tea leaves) are easily squeezed and sheared, resulting in an increase in broken pieces and damage to the shape, which is difficult to meet the requirements of high-quality tea for integrity. In addition, the screw structure is difficult to adjust when changing the type of material or adjusting the filling amount, and has poor adaptability.

[0004] According to the search, the "medicine powder filling and metering equipment and medicine powder filling device" (authorized publication date: January 3, 2023) with publication number CN113493002B uses a volumetric metering slider structure to realize quantitative filling through the reciprocating motion of the metering hole between two stations. Although this design avoids the problem of powder clumping caused by stirring and squeezing, it is suitable for good flowability of medicine powder, but for strip-shaped, fluffy and easily entangled tea materials, the metering hole is difficult to achieve stable and uniform natural dropping during the filling stage, and may cause inaccurate metering due to bridging or blocking. At the same time, if tea is stuck in the gap between the slider and the support table during the reciprocating motion of the slider, it may still cause squeezing damage, and cannot effectively protect the integrity of strip-shaped tea.

[0005] The above problems show that the existing filling device either relies on high-damage mechanical pushing (such as screw feeding) or is only suitable for powdery materials with specific physical properties, and cannot meet the comprehensive needs of strip-shaped tea materials in terms of quantitative accuracy, low damage and filling stability. Therefore, it is urgent to provide a filling device to solve the problems of high breakage rate, inaccurate quantitative and poor adaptability when processing fragile strip-shaped materials in the prior art.
