The two ends of the connecting column 2101 are respectively connected to the middle of the first circular baffle 2102 and the middle of the second circular baffle 2103. The functional layer 13 is rolled into a U shape when passing through the gap 1006 between the first circular baffle 2102 and the second circular baffle 2103. The first circular baffle 2102 and the second circular baffle 2103 in the implementation of the present application can be located on both sides of the differential roller 20.

[0049] Based on the above embodiments, the tail end of the traction cavity 701 of the embodiment of the present application is provided with a detection device 8 and a knife disc 9 in sequence, the detection device 8 is used to detect the capsule 1302 in the functional layer 13, and the knife disc 9 is used to cut the formed linear paper tube.

[0050] The embodiment of the present application does not specifically limit the detection device 8. The detection device 8 can be a microwave sensor. The microwave sensor uses microwaves emitted by the transmitting antenna. When the microwaves encounter the object to be measured, they will be absorbed or reflected, resulting in a change in power. The receiving antenna receives the microwaves that pass through the object to be measured or are reflected by the object to be measured, and converts them into electrical signals, which are then processed by the measuring circuit to achieve microwave detection. Correspondingly, a controller connected to the detection device 8 and the cutter disc 9 can also be included. The controller can control the cutter disc 9 to cut the linear paper tube within a preset time according to the detection signal sent by the detection device 8. Since the distance between the detection device 8 and the cutter disc 9 is fixed, the transmission speed of the linear paper tube is fixed. The cutter disc 9 is controlled according to the distance and speed to prevent the cutter disc 9 from cutting the capsule 1302 on the functional layer 13.

[0051] Based on the above embodiments, Figure 14 is a structural diagram of a limiting device provided in an embodiment of the present application. As shown in Figure 14, the limiting device 10 is arranged on the movement path of the outer layer forming paper 12 conveyed to the head end of the third forming component 3.

The screw nut mechanism 1002 is arranged on the first support plate 1001, and the bottom surface of the second support plate 1003 is connected to the nut on the screw nut mechanism 1002. The first pressing plate 1004 and the second pressing plate 1005 are adjustable in position on the top surface of the second support plate 1003 to change the width of the gap 1006 between the first pressing plate 1004 and the second pressing plate 1005. The gap 1006 between the first pressing plate 1004 and the second pressing plate 1005 is used for the outer layer forming paper 12 to pass through.

[0052] In the embodiment of the present application, the moving direction of the second support plate 1003 is perpendicular to the conveying direction of the outer layer forming paper 12, and the length direction of the gap 1006 between the first pressing plate 1004 and the second pressing plate 1005 is parallel to the conveying direction of the outer layer forming paper 12. The forward and reverse rotation of the lead screw in the lead screw nut mechanism 1002 can make the second support plate 1003 move along the length direction of the lead screw, so that the outer layer forming paper 12 can smoothly enter the third forming component 3, and the width of the gap 1006 between the first pressing plate 1004 and the second pressing plate 1005 is adjustable, so that it can be used for outer layer forming paper 12 of different widths. As to how to realize the adjustable position of the first pressing plate 1004 and the second pressing plate 1005 arranged on the top surface of the second supporting plate 1003, it can be that oblong holes 1009 are opened on the first pressing plate 1004 and the second pressing plate 1005, the length direction of the oblong holes 1009 is parallel to the width direction of the outer forming paper 12, and the locking nut 1007 passes through the oblong hole 1009 and is connected with the screw hole on the second supporting plate 1003, and the nut can slide along the length direction of the oblong hole 1009 to change the distance between the first pressing plate 1004 and the second pressing plate 1005. When the locking nut 1007 is tightened, the first pressing plate 1004 and the second pressing plate 1005 can be fixed on the second supporting plate 1003.

[0053] Based on the above embodiments, the embodiments of the present application also include an industrial camera, which is arranged at the conveying path of the functional layer 13. The industrial camera is used to photograph the functional layer 13 and upload the photographed pictures to a terminal (mobile phone or computer) to facilitate users to check the integrity of the capsule 1302 on the functional layer 13.
