The sealing of cigarette products is achieved by tape to close the cigarette boxes. However, in actual production, situations such as the tape being pulled and broken often occur, indirectly affecting the equipment operation efficiency and product quality.

[0048] Therefore, the present application provides a tape supply mechanism with a compensation function to solve the problem that the tape in the carton sealer is often broken during the packaging of cigarette cartons by the carton sealer.

[0049] Specifically, please refer to Figure 1 , Figure 2 and Figure 4 , a tape supply mechanism with a compensation function, including a tape reel 1, a tape compensation assembly 3, a tape tensioning and guiding assembly 6 and a tape tension monitoring member 13; the tape reel 1 is rotatably arranged on the upper part of the substrate 2, the tape compensation assembly 3 is located downstream of the tape reel 1, the tape compensation assembly 3 includes a tape compensation motor 4 and a tape compensation guide pulley 5, the tape compensation motor 4 is located at the lower part of the substrate 2 downstream of the tape reel 1, the output shaft of the tape compensation motor 4 rotatably connected to the substrate 2 is connected to the tape compensation guide pulley 5 located on the upper part of the substrate 2, the tape tensioning and guiding assembly 6 is located downstream of the tape compensation motor 4, the tape tensioning and guiding assembly 6 includes a first rotating seat 7, a tensioning and guiding pulley 8 and a first tension spring 9, the tensioning and guiding pulley 8 is located downstream of the tape compensation motor 5, the tensioning and guiding pulley 8 is connected to one end of a tensioning swing arm 10, the other end of the tensioning swing arm 10 is connected to the side wall of the first rotating seat 7, the bottom of the first rotating seat 7 is rotatably connected to the top of the substrate 2, one end of a first support arm 11 connected to the side wall of the first rotating seat 7 is connected to one end of the first tension spring 9, the other end of the first tension spring 9 is connected to a first connecting column 12 connected to the upper part of the substrate 2, there is an included angle between the first tension spring 9 and the tensioning swing arm 10, the tape tension monitoring member 13 is located within the swinging range of the tensioning swing arm 10, the tape tension monitoring member 13 includes a tape over-tightness detector 14 and a tape normal tightness detector 15, the tape over-tightness detector 14 and the tape normal tightness detector 15 are respectively electrically connected to the tape compensation motor 4 through a controller, the tape over-tightness detector 14 and the tape normal tightness detector 15 are located within the swinging range of the tensioning swing arm 10, the tensioning swing arm 10 is respectively in movable contact with the tape over-tightness detector 14 and the tape normal tightness detector 15, a second support arm 17 connected to the bottom of a tape suction cup baffle 16 located downstream of the tensioning swing arm 10 is connected to the side wall of a second rotating seat 18 rotatably connected to the top of the substrate 2, one end of a third support arm 19 connected to the side wall of the second rotating seat 18 is connected to one end of a second tension spring 20, the other end of the second tension spring 20 is connected to a second connecting column 21 connected to the upper part of the substrate 2.

[0050] In actual use, when using a tape supply mechanism with a compensation function to package a cigarette box containing strip cigarettes, first, the transparent roll tape for packaging the cigarette box is sleeved on the tape reel 1, and the starting end of the transparent tape is sequentially wound around the tape compensation guide wheel 5 and the tension guide wheel 8 to the tape suction cup baffle 16 for adsorption, waiting for the subsequent packaging work of the cigarette box containing strip cigarettes; when the cigarette box containing strip cigarettes and to be packaged passes through the tape suction cup baffle 16, the transparent tape adsorbed on the tape suction cup baffle 16 adheres to the side wall joint of the advancing cigarette box. As the cigarette box continues to move forward, on the one hand, the advancing cigarette box pushes open the tape suction cup baffle 16, and on the other hand, it drives the adhered tape to continue moving forward; during the process that the advancing cigarette box drives the adhered tape to continue moving forward, the tape will be tightened and the tape tension also changes. Under the action of the tape tension, the tension swing arm 10 connected to the tension guide wheel 8 swings between the tape over-tightness detector 14 and the tape normal tightness detector 15 to relieve the tape tightness; during the swinging process of the tension swing arm 10 connected to the tension guide wheel 8 between the tape over-tightness detector 14 and the tape normal tightness detector 15, if the tension swing arm 10 swings to the tape normal tightness detector 15 and touches it, the tape normal tightness detector 15 will not control the tape compensation motor 4 to drive the tape compensation guide wheel 5 to rotate through the controller, so that the tape tightness is within the normal range; if the tension swing arm 10 swings to the tape over-tightness detector 14 and touches it, the tape over-tightness detector 14 controls the tape compensation motor 4 to drive the tape compensation guide wheel 5 to rotate through the controller, so as to drive the transparent tape wound around the tape compensation guide wheel 5 to rotate and release a section of the transparent roll tape wound around the tape reel 1 in a short time to relieve the tape tightness and avoid the situation that the tape breaks due to excessive tension, thereby solving the problem that the tape in the carton sealer is pulled and broken during the packaging process of the cigarette box with the carton sealer.

[0051] It should be noted that the tape over-tightness detector 14 and the tape normal tightness detector 15 are sensors for detecting in place in the prior art.

The first detection hole 25 and the second detection hole 26 are annularly distributed, and the first detection hole 25 is surrounded by the second detection hole 26. A tape detector 27 is correspondingly arranged on the substrate 2 below the first detection hole 25, and a tape disk detector 28 is arranged on the substrate 2 below the second detection hole 26.

[0054] It should be noted that both the tape detector 27 and the tape disk detector 28 are prior arts and have not been improved or designed, so their structures will not be described in detail. Among them, the tape detector 163 and the tape disk detector 164 can be pulse counting detectors.
