[0023] Work process: 1) Place the transparent roll of tape for sealing the cigarette box onto the tape reel, and let the starting end of the transparent tape wrap around the tape compensation guide wheel and the tension guide wheel in sequence until it is adsorbed at the tape suction cup baffle, waiting for the subsequent sealing work of the cigarette box containing the pack of cigarettes.

[0024] 2) When the cigarette box containing the cigarettes and which needs to be sealed passes the tape suction cup baffle, the transparent tape adsorbed on the tape suction cup baffle adheres to the seam of the side wall of the moving cigarette box. As the cigarette box continues to move forward, the moving cigarette box pushes open the tape suction cup baffle on one hand, and continues to move forward with the adhered tape on the other hand.

[0025] 3) As the moving smoke box continues to move with the adhesive tape, the tape will be tightened and the tape tension will change. Under the action of the tape tension, the tension swing arm connected to the tension guide wheel will swing between the tape tension too tight detector and the tape tension normal detector to relieve the tape tension.

[0026] 4) During the swinging process between the over-tension detector and the normal tension detector, if the tension swing arm swings to and contacts the over-tension detector, the over-tension detector will control the belt compensation motor to rotate the belt compensation guide wheel via the controller. This will cause the transparent tape wound around the belt compensation guide wheel to rotate, releasing a section of the transparent tape wound on the tape reel in a short time to relieve the tension of the tape. If the tension swing arm swings to and contacts the normal tension detector, the normal tension detector will not control the belt compensation motor to rotate the belt compensation guide wheel via the controller, thus keeping the tension of the tape within the normal range.

[0027] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0028] This invention integrates a tape supply mechanism with compensation function, comprising a tape reel, a tape compensation component, a tape tension guide component, a tape tension monitoring component, and a base plate. The tape tension over-tightness detector and the tape tension normality detector in the tape tension monitoring component are located within the swing range of the tension swing arm in the tape tension guide component. The tension swing arm is in contact with the tape tension over-tightness detector and the tape tension normality detector, respectively. The tape tension over-tightness detector and the tape tension normality detector are electrically connected to a tape compensation motor via a controller. When the tension swing arm swings to the point where the tape tension over-tightness detector detects that the tape is too tight, the over-tightness detector will drive the tape compensation guide wheel, which is wound with tape, to rotate via the controller and tape compensation motor. This releases a portion of the tape on the tape reel, easing the tape tension and preventing the tape from breaking due to excessive tightness. This solves the problem of tape breaking during the sealing process of cigarette boxes using a sealing machine. Attached Figure Description

[0046] Example

[0047] In the cigarette production process, the packing and sealing of carton cigarettes is an important step. The cigarette boxes are sealed with tape. However, in actual production, the tape often breaks, which indirectly affects the operating efficiency of the equipment and the quality of the products.

[0048] Therefore, this application proposes a tape supply mechanism with a compensation function to solve the problem that the tape in the sealing machine is often broken when sealing cigarette boxes.

[0049] Specifically, please refer to Figures 1, 2, and 4. A tape supply mechanism with compensation function includes a tape reel 1, a tape compensation component 3, a tape tension guide component 6, and a tape tension monitoring component 13. The tape reel 1 is rotatably disposed on the upper part of a substrate 2. The tape compensation component 3 is located downstream of the tape reel 1. The tape compensation component 3 includes a tape compensation motor 4 and a tape compensation guide wheel 5. The tape compensation motor 4 is located on the lower part of the substrate 2 downstream of the tape reel 1. The output shaft of the tape compensation motor 4, which is rotatably connected to the substrate 2, is connected to the tape supply mechanism located on the upper part of the substrate 2. A compensating guide wheel 5 is connected to the belt tensioning guide assembly 6, which is located downstream of the belt compensating motor 4. The belt tensioning guide assembly 6 includes a first rotating seat 7, a tensioning guide wheel 8, and a first tensioning spring 9. The tensioning guide wheel 8 is located downstream of the belt compensating motor 4 and 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 base plate 2. One end of the first support arm 11 connected to the side wall of the first rotating seat 7 is connected to one end of the first tensioning spring 9. The other end of the tension spring 9 is connected to the first connecting post 12 connected to the upper part of the base plate 2. The first tension spring 9 and the tension swing arm 10 have an angle between them. The tape tension monitoring device 13 is located within the swing range of the tension swing arm 10. The tape tension monitoring device 13 includes a tape tension over-tightness detector 14 and a tape tension normality detector 15. The tape tension over-tightness detector 14 and the tape tension normality detector 15 are electrically connected to the tape compensation motor 4 through a controller. 15 is located within the swing range of the tension swing arm 10. The tension swing arm 10 is in active contact with the tape tension over-tightness detector 14 and the tape tension normality detector 15 respectively. The second arm 17, which is located downstream of the tension swing arm 10 and connected to the bottom of the tape suction cup baffle 16, is connected to the side wall of the second rotating seat 18, which is rotatably connected to the top of the substrate 2. One end of the third arm 19, which is connected to the side wall of the second rotating seat 18, is connected to one end of the second tension spring 20. The other end of the second tension spring 20 is connected to the second connecting post 21, which is connected to the upper part of the substrate 2.

[0050] In practical applications, when using a tape supply mechanism with a compensation function to seal cigarette cartons, the transparent roll of tape for sealing the cigarette cartons is first attached to the tape reel 1, and the starting end of the transparent tape is wound sequentially around the tape compensation guide wheel 5 and the tension guide wheel 8 until it is adsorbed at the tape suction cup baffle 16, awaiting the subsequent sealing work of the cigarette cartons; when the cigarette cartons containing cigarette cartons that need to be sealed pass the tape suction cup baffle 16, the transparent tape adsorbed on the tape suction cup baffle 16 adheres to the roll. At the seam of the side wall of the cigarette box, as the cigarette box continues to move forward, it pushes against the tape suction cup baffle 16 while continuing to move forward with the adhered tape. During this process, the tape is tightened, and the tape tension changes. Under the action of the tape tension, the tension swing arm 10, connected to the tension guide wheel 8, swings between the tape tension over-tightness detector 14 and the tape tension normality detector 15 to alleviate the tape tension. Tightness; During the swinging process between the over-tightness tape tension detector 14 and the normal tape tension detector 15, if the tension swinging arm 10 swings to the normal tape tension detector 15 and contacts it, the normal tape tension 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 tension is within the normal range; If the tension swinging arm 10 swings to the over-tightness tape tension detector 14 and contacts it, the over-tightness tape tension 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 on the tape compensation guide wheel 5 to rotate, thereby releasing a section of the transparent roll tape wound on the tape reel 1 in a short time, so as to relieve the tension of the tape and avoid the tape from breaking due to excessive tension, thereby solving the problem of the tape being pulled apart in the sealing machine during the sealing of cigarette boxes by the sealing machine.

[0051] It should be noted that the over-tight tape detector 14 and the normal tape tension detector 15 are existing sensors that detect when the tape tension is in place. The over-tight tape detector 14 and the normal tape tension detector 15 can also be limit switches. These are existing technologies, and no improvements or designs have been made to them.

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

[0063] This utility model integrates a tape supply mechanism with compensation function, comprising a tape reel 1, a tape compensation component 3, a tape tension guide component 6, a tape tension monitoring component 13, and a base plate 2. The tape tension over-tightness detector 14 and the tape tension normality detector 15 in the tape tension monitoring component 13 are located within the swing range of the tension swing arm 10 in the tape tension guide component 6. The tension swing arm 10 respectively moves in contact with the tape tension over-tightness detector 14 and the tape tension normality detector 15. The normal detector 15 is electrically connected to the tape compensation motor 4 through the controller. When the tension swing arm 10 swings to the point where the tape tension over-tightness detector 14 detects that the tape is too tight, the tape tension over-tightness detector 14 will drive the tape compensation guide wheel 5, which is wrapped with tape, to rotate through the tape compensation motor 4. This will release a section of tape on the tape reel, thus relieving the tension of the tape and preventing it from being pulled apart due to excessive tightness. This solves the problem of tape being pulled apart in the sealing machine during the sealing process of cigarette boxes.
