Description

Full servo packaging capper Technical Field The invention relates to the technical field of packaging equipment, in particular to a full-servo packaging sealing machine. Background The disposable diaper is used as a disposable sanitary article, and in the production process, after the core absorber is manufactured, reliable packaging and sealing procedures are required. The process not only provides physical protection for the product, prevents the product from being polluted or damped in the processes of storage, transportation and sales, but also can maintain the clean and sanitary state of the product, and ensures the sealing integrity of the packaging bag, which is important for guaranteeing the quality of the product, prolonging the shelf life and improving the brand image. Therefore, the realization of efficient, accurate and well-sealed package sealing is an indispensable key link in paper diaper production. The package sealing process comprises two actions of heat sealing and cutting, wherein the packaging film is required to be subjected to heat pressing sealing and then cut and separated to form independent packages. At present, the common package sealing equipment in the market generally adopts mutually independent driving mechanisms to respectively control the heat sealing and cutting actions. The design has the obvious defects that firstly, two sets of driving mechanisms lead to complex mechanical structure and increased parts, thereby not only increasing the manufacturing cost of equipment, but also improving the subsequent maintenance difficulty and failure rate. Second, and more critical, is that timing coordination of two independent actions is extremely difficult. In practical operation, the start and stop and the speed of the sealing mechanism and the cutting mechanism must be kept highly synchronous, any minor timing error or control delay may cause serious quality problems, for example, the occurrence of 'unsealing and cutting first' causes unqualified opening of the packaging bag, or 'unsealing and cutting after sealing' causes bag connection of products, which not only causes waste of packaging materials, but also directly affects production efficiency and yield. Therefore, there is a need to design a package sealer. Disclosure of Invention The invention aims to provide a full-servo packaging sealing machine, which solves the problems of complex structure and difficult time sequence coordination caused by the control of different driving mechanisms of heat sealing and cutting actions in the prior art.
