[0002] The connecting machine is used to connect two short cigarettes to the two ends of the double-length filter rod respectively, and wrap and bond the connecting paper to the outer circumference of the double-length filter rod and the two short cigarettes to form a double-length cigarette. The double-length cigarette is then cut into two finished cigarettes of equal length along the length direction. Among them, the surface of the connecting paper facing the double-length filter rod and the short cigarette is provided with a glue-coated area and a glue-free area. The glue-coated area is coated with glue for bonding the double-length filter rod and the short cigarette, and the glue-free area is not coated with glue. When connecting the double-length filter rod and the short cigarette, according to the process requirements, the glue-free area needs to be covered on the midpoint of the double-length filter rod along its length to avoid glue leakage at the end of the filter rod after cutting. However, the applicant found through quality inspection that there was glue leakage at the end of the filter rod of the finished cigarette, which would seriously affect the product quality and consumer experience.

A glue groove 4 is provided on the outer circumference of the glue roller 3. The glue groove 4 contains glue liquid. When the glue roller 3 rotates, it can drive the glue roller 2 to rotate and apply the glue liquid on the outer circumference of the glue roller 2 to form a glue coating area. The glue roller 3 can be moved relative to the glue roller 2 along a first direction ( Figure 2 The first direction is the axial direction of the glue coating roller 2.

[0030] By adopting the above technical solution, the glue roller 3 can drive the glue roller 2 to rotate by pressing the glue roller 3 against the glue coating roller 2; specifically, the glue roller 3 is connected to a driving mechanism, and the driving mechanism is used to drive the glue roller 3 to rotate.

[0031] Furthermore, if Figure 1 and Figure 2As shown, a glue cylinder 5 is provided on the frame 1, and glue liquid is stored inside the glue cylinder 5.
