Description

Technical Field

[0001] The present application relates to the technical field of paper tube forming, and in particular to a strip-shaped linear paper tube forming device. Background Art

[0002] Compared with the traditional spiral winding paper tube forming process, the straight paper tube forming does not need to use the previous spiral winding method to form the paper tube. Instead, the paper tape is pulled out in a straight line and then rolled into a straight paper tube. The inner and outer walls are smooth and flat, and the height of the interface gap on both sides is consistent. The formed paper tube has a high appearance quality and has a higher production speed and lower manufacturing cost.

[0003] To enhance the sensory experience, flavorings are added to cigarette paper tubes to enhance the aroma of the cigarette, giving smokers a richer flavor experience. To improve smoking comfort, cooling materials are added to paper tubes to lower the temperature of the smoke, reducing the burning sensation in the mouth. Currently, to achieve cooling or flavoring functions in straight paper tubes, flavorings or cooling materials are typically added after the tubes are manufactured. However, this results in low overall production efficiency.

[0041] Based on the above embodiments, Figure 1 and Figure 2 As shown, the traction assembly 7 of the embodiment of the present application includes a traction chamber 701, a cloth tape reel 702 and a rotating motor (not shown in the figure).

The ends of the connecting post 2101 are connected to the middle portion of the first circular baffle 2102 and the middle portion of the second circular baffle 2103, respectively. 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. In the embodiment of the present application, the first circular baffle 2102 and the second circular baffle 2103 can be located on both sides of the differential roller 20.

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

[0050] The present embodiment of the present application does not specifically limit the detection device 8. The detection device 8 may be a microwave sensor. The microwave sensor utilizes microwaves emitted by a transmitting antenna. When the microwaves encounter the object being measured, they are absorbed or reflected, resulting in a change in power. The receiving antenna receives the microwaves that have passed through or reflected from the object being measured and converts them into electrical signals, which are then processed by the measurement circuit to achieve microwave detection. A controller may also be included, respectively connected to the detection device 8 and the cutter disc 9. The controller can control the cutter disc 9 to cut the linear paper tube within a preset time based on the detection signal transmitted 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 based on the distance and speed to prevent the cutter disc 9 from cutting the capsules 1302 on the functional layer 13.

[0051] Based on the above embodiments, Figure 14 A structural diagram of a limiting device provided in an embodiment of the present application is shown in FIG. Figure 14 As shown, the limiting device 10 is arranged on the movement path of the outer layer forming paper 12 being conveyed to the head end of the third forming component 3, and the limiting device 10 includes a first support plate 1001, a screw and nut mechanism 1002, a second support plate 1003, a first pressure plate 1004 and a second pressure plate 1005. The screw and 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 and nut mechanism 1002. The first pressure plate 1004 and the second pressure plate 1005 are adjustable on the top surface of the second support plate 1003 to change the width of the gap 1006 between the first pressure plate 1004 and the second pressure plate 1005. The gap 1006 between the first pressure plate 1004 and the second pressure plate 1005 is used for allowing the outer layer forming paper 12 to pass through.

[0052] In the embodiment of the present application, the movement direction of the second support plate 1003 is perpendicular to the conveying direction of the outer 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 forming paper 12. The forward and reverse rotation of the lead screw in the lead screw-nut mechanism 1002 allows the second support plate 1003 to move along the length direction of the lead screw, allowing the outer forming paper 12 to smoothly enter the third forming component 3. The width of the gap 1006 between the first pressing plate 1004 and the second pressing plate 1005 is adjustable to accommodate outer forming paper 12 of varying widths. Regarding how to achieve adjustable positions of the first pressing plate 1004 and the second pressing plate 1005 on the top surface of the second supporting plate 1003, an oblong hole 1009 can be provided on both the first pressing plate 1004 and the second pressing plate 1005, and the length direction of the oblong hole 1009 is parallel to the width direction of the outer forming paper 12. A locking nut 1007 passes through the oblong hole 1009 and is connected to the screw hole on the second supporting plate 1003. 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 embodiment, the embodiment of the present application also includes 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.
