Background In the production of multi-section composite filter rods for heating cigarettes, it is often necessary to adopt linear composite processes for base rods (such as core base rods and hollow base rods) of different materials to form the multi-section composite filter rods. The process is generally to sequentially connect the pre-cut tobacco core segments and the hollow segments on a straight or nearly straight track through reciprocating pushing, aligning, gluing, pasting and other actions. However, the linear composite process has obvious defects in practical application, namely, on one hand, the tobacco core base rod is softer and is easy to compress in a composite alignment link, so that the actual length and the theoretical length deviate, the relative position between materials of each section is difficult to accurately control, and phase deviation is easy to occur, and on the other hand, a small gap between the end faces of adjacent base rod sections exists in a linear composite process route, so that the processing quality of subsequent procedures is influenced. The above problems together lead to high reject rates and excessive consumption of auxiliary materials. Therefore, how to provide a manufacturing method and equipment capable of realizing high-precision alignment and zero-clearance compounding of each base rod segment so as to improve quality and reduce loss is a problem to be solved by those skilled in the art.
