Description

Technical Field

[0001] This utility model relates to the field of filling and sealing technology, and in particular to a disc filling and sealing machine. Background Technology

[0002] After the powder products are produced, they need to be filled and sealed to ensure that they are not contaminated during transportation. The filling and sealing process involves steps such as cup dropping, material feeding, cleaning, sealing and cup discharging. The commonly used method is to set up a linear filling and sealing machine, which sets up several processing steps in sequence along the linear conveying direction. This method has a large footprint and is expensive.

[0003] Chinese patent application number 202410837071.0 discloses a disc-type high-efficiency fully automatic powder filling and sealing machine. The disc body has multiple support slots. Although it has a high production capacity, the structure corresponding to each processing step is complex and requires sufficient installation space. While the disc-type design requires less space than the linear design, the disc diameter is relatively large due to its multi-row operation, making it unsuitable for filling and sealing applications with low capacity requirements. The disc body supporting each processing step is a thin sheet, which needs to withstand a certain downward pressure during the feeding and cleaning processes, making it easily damaged. Furthermore, the feeding and cleaning processes require close contact with the cup rim; ensuring close contact without damaging the cup is a pressing problem. (Referring to...) Figure 5 The power element that drives the disc to rotate is a cam divider. The cam divider requires an additional drive motor and sprocket and chain assembly to transmit power, which is complex and requires more installation space.

[0004] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a disc filling and sealing machine. Utility Model Content
