Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cold stamping forming aluminum, in particular to a cold stamping forming aluminum packaging sealing device and a sealing method thereof. BACKGROUND

[0002] In the field of pharmaceutical packaging, cold stamping forming aluminum is widely used in the packaging of solid drugs such as tablets and capsules due to its good barrier property, sealing property and formability. During the packaging process of cold stamping forming aluminum, the sealing device is one of the key equipment. Its main function is to accurately align the formed cold stamping aluminum shell with the aluminum film and complete the sealing to ensure the sealing property and safety of the pharmaceutical packaging. The existing sealing device for cold stamping forming aluminum packaging usually includes a rack, a guide seat arranged on the rack, an aluminum film conveying mechanism and a limiting structure for limiting the aluminum film. Among them, the guide seat is used for guiding and positioning the formed cold stamping aluminum shell to ensure that the aluminum shell is in the correct position during the sealing process; the aluminum film conveying mechanism is used to convey the aluminum film to the sealing station, and the limiting structure is used to limit the conveying path and position of the aluminum film to prevent the aluminum film from shifting during the conveying process and ensure the accurate fitting of the aluminum film and the aluminum shell. However, in actual production process, there are various size specifications of pharmaceutical packaging. When different size pharmaceutical packaging needs to be replaced, due to the lack of linkage adjustment mechanism between the guide seat and the aluminum film in the existing sealing device, the operator needs to replace the matching guide seat according to the new packaging size first, and then disassemble and adjust the fixing structure (such as bolt connection structure, buckle positioning structure, etc.) of the guide seat to ensure that the installation position of the guide seat meets the new packaging positioning requirements. At the same time, the limiting structure (such as limiting baffle, adjusting screw, etc. composed of limiting assembly) of the aluminum film needs to be disassembled, adjusted or replaced according to the change of the width and other parameters of the aluminum film matched with the new size packaging to effectively limit the new specification aluminum film. This operation mode of adjusting the fixing structure of the guide seat and the limiting structure of the aluminum film separately not only has complicated steps and takes a long time, which seriously affects the production change efficiency and increases the production cost; and in the two independent adjustment processes, it is difficult to accurately match the positioning of the guide seat and the limiting position of the aluminum film due to the operation error, which affects the sealing precision, leads to the decline of the sealing property of the packaging, and even causes the problem of unqualified pharmaceutical packaging. Therefore, how to realize the synchronous adjustment of the guide seat fixing structure and the aluminum film limiting structure under the demand of different size packaging has become a technical problem to be solved for the current cold stamping forming aluminum packaging sealing device.
