[0032] In the prior art, after using a suction cup to adsorb and fix a stack of materials, a cutting knife is used to cut the wrapping tape to achieve automatic disassembly of the wrapping tape. However, during the cutting process, the following problems will occur: 1. The adsorption force of the suction cup itself on the stack of materials is insufficient, resulting in unstable fixation of the stack of materials; 2. There is no corresponding fixing part for the wrapping tape, and during the cutting by the cutting knife, displacement will occur, which is likely to cause cutting errors; 3. There are differences in the position and shape of the bulged part of the wrapping tape, and the fixed-point cutting by the cutting knife is likely to cause cutting errors; the above problems will all affect the efficiency of cigarette packaging production.

[0033] To solve the above problems, this embodiment provides a cigarette packaging supply line, including a wrapping tape cutting device. Among them, refer to Figures 1 - 3, the wrapping belt cutting mechanism includes a fixing component 10 and a cutting component 20. The fixing component 10 includes a bearing member 11 and a belt pressing member 12. A plurality of bearing members 11 are arranged at intervals in the first direction and the second direction. In this embodiment, the bearing members 11 are arranged in a 2x3 specification; adsorption holes are provided on the bearing members 11, and the stack is fixed to the bearing members 11 through the adsorption holes; the belt pressing member 12 is arranged on one side of the bearing member 11 and can move along the third direction to press or release the stack and the wrapping belt; the first direction (X-axis direction), the second direction (Y-axis direction), and the third direction (Z-axis direction) are all perpendicular; the cutting component 20 is arranged outside the belt pressing member 12. The cutting component 20 includes a support seat 21, a cutting knife 22, and an elastic member 23. The support seat 21 can move along the first direction or the second direction. The cutting knife 22 is rotatably arranged on the support seat 21 to cut the wrapping belt. The elastic member 23 is connected between the support seat 21 and the cutting knife 22 to elastically adjust the cutting angle and height of the cutting knife 22. By vacuum adsorbing the stack through the adsorption holes, the fixing stability of the stack is improved; the belt pressing member 12 is used to press the wrapping belt and the elastic member 23 is provided to enable the cutting knife 22 to self-adjust the cutting angle and height by the elastic force of the elastic member 23, which improves the cutting accuracy and the production efficiency of cigarette packaging.

[0034] Specifically, the bearing member 11 is set as a suction cup. Specifically, the suction cup can be made of nitrile rubber, polyurethane rubber, fluororubber, silicone rubber, etc.; the center of the suction cup is recessed downward. When the stack is placed on the suction cup, a small cavity will be formed in the recessed part, and this cavity can generate a vacuum environment to fix the stack; the adsorption holes are arranged at the center of the suction cup. The fixing component 10 further includes a first hose. One end of the first hose is connected to the adsorption hole, and the other end is connected to a vacuum component. The vacuum component makes the bearing member 11 have adsorption force through the first hose. In this embodiment, the vacuum component is set as a vacuum pump, such as a rotary vane pump, a reciprocating pump, a slide valve pump, a Roots pump, a molecular pump, a liquid ring pump, etc. In other embodiments, the vacuum component can also be set as a vacuum pump unit or a vacuum generator, etc.

[0035] Further, the diameter of the first hose is greater than 10 mm to be able to pass a larger gas flow rate and increase the stability of fixing the stack. In this embodiment, three suction cups arranged at intervals in the second direction are taken as a group, and the first hoses between a group of suction cups are communicated with each other. A group of suction cups realizes vacuum adsorption through one vacuum component to save costs.

[0036] Further, the fixing component 10 further includes a detection component. The detection component is arranged in the first hose and is communicatively connected to the upper computer. The detection component can detect the vacuum degree in the first hose. Specifically, the detection component can adopt a thermal conductivity vacuum gauge, a Pirani vacuum gauge, a capacitance diaphragm vacuum gauge, an ionization vacuum gauge, etc., which will not be elaborated here. When the vacuum degree in the first hose does not reach the specified value, the detector will send an alarm to the upper computer and stop production to avoid damaging the stack due to unstable fixation and causing economic losses.

[0037] Further, the fixing assembly 10 further includes a second hose and a solenoid valve. One end of the second hose is connected to the first hose, and the other end leads to the atmospheric environment. The solenoid valve is arranged at the connection of the first hose and the second hose, and the solenoid valve can make the second hose communicate with or disconnect from the first hose. Specifically, only one second hose is connected to the first hose under each suction cup to save material costs. The solenoid valve is an existing technology and will not be elaborated here.

[0038] Further, the fixing assembly 10 further includes feet 13 and a driving member 14. The feet 13 are provided with sliding grooves along the third direction, and the pressing belt member 12 is provided with sliding blocks. The driving member 14 can drive the pressing belt member 12 to slide on the feet 13 along the third direction. Specifically, two feet 13 are provided, and the two feet 13 are triangular in shape to support the pressing belt member 12. The driving member 14 is set as a hydraulic cylinder or an air cylinder to drive the pressing belt member 12 to move along the third direction. In this embodiment, the pressing belt member 12 is set as a pressing rod, and the pressing rod extends along the first direction or the second direction to press the wrapping belt when the wrapping belt is in any position. Specifically, the moving direction of the cutting knife 22 is the same as the extending direction of the pressing rod.

[0039] Further, since the wrapping belt has irregular bulges rubbed out in the previous process, the cutting knife 22 is in a hook shape so that during the moving process, it can extend into the gaps of the bulges, thereby smoothly cutting the wrapping belt. The blade of the cutting knife 22 is inclined, and the inclined angle is convenient for cutting. During the moving process of the cutting knife 22, the cutting knife 22 cannot cut the wrapping belt when it initially contacts the wrapping belt. At this time, since the cutting knife 22 can rotate and is provided with an elastic member 23, the wrapping belt will apply a force to the cutting knife 22, thereby driving the elastic member 23 to adjust the position and angle of the cutting knife 22. During the adjustment process, the cutting knife 22 can always have an angle to cut the wrapping belt.

[0040] Specifically, the elastic member 23 is set as a spring, and the cutting assembly 20 further includes a hinge 24. The cutting knife 22 is rotatably arranged on the support seat 21 through the hinge 24. In other embodiments, the elastic member 23 can be set as a soft rubber column, etc., and a rotating shaft can also be used instead of the hinge 24.

[0041] Further, the cutting assembly 20 includes a slide rail 25. The support seat 21 is set as a linear electric cylinder or a hydraulic cylinder. While supporting the cutting knife 22, the support seat 21 can move on the slide rail 25 by itself to drive the cutting knife 22 to move along the extending direction of the pressing rod. Further, the cutting assembly 20 further includes a proximity sensor 26, and the proximity sensor 26 can detect the position of the support seat 21 and control the movement of the support seat 21.

[0042] Further, the wrapping belt cutting mechanism further includes a vision component 30. The vision component 30 is disposed on the periphery of the carrier 11 and can locate the position of the stack material and is communicatively connected to the fixing component 10. Specifically, the vision component 30 includes a vision camera. The vision camera can capture the border of the stack material to calculate the center point of the stack material. If the position of the stack material is inaccurate, for example, it is tilted, it can alarm the operator in time for processing to avoid damaging the stack material and causing economic losses.

[0043] Further, the wrapping belt cutting mechanism further includes a housing 40. The housing 40 can accommodate the fixing component 10, the cutting component 20, and the vision component 30, enabling the wrapping belt cutting mechanism to achieve modular integration and facilitating mass application.

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here.
