[0002] Aluminum foil for cigarettes is made of aluminum foil and inner lining paper compounded by adhesive. Its main function is to wrap the cigarettes in the cigarette box, create a suitable storage environment for the cigarettes, maintain the moisture of the cigarettes, and delay the loss of the aroma components of the cigarettes. With the development of the tobacco industry and the improvement of scientific and technological levels, cigarette companies have continuously increased their requirements for the use of aluminum foil. The inner lining paper is an important material for cigarette packaging. It plays an important role in moisture-proofing and aroma preservation, and can ensure the stable smoking quality of cigarettes during storage. With good barrier properties, composite aluminum foil inner lining paper and vacuum aluminum-plated inner lining paper are widely used at home and abroad.

[0003] However, there are many problems with the existing technology. When printing the liner paper, the unwinding mechanism is used to unwind the paper, and then the paper is rewound after printing by the printing device.

DETAILED DESCRIPTION

[0029] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0030] like Figure 1-Figure 2As shown, a reeling mechanism for lining paper compounding includes a frame 1, a main roller mechanism 2, a reeling auxiliary roller 31 mechanism and a static electricity removal device, the main roller mechanism 2 is used to place the lining paper roll, the reeling auxiliary roller 31 mechanism is used to assist the main roller mechanism 2 in reeling, and the static electricity removal device is used to remove static electricity from the lining paper; the reeling auxiliary roller 31 mechanism includes an auxiliary roller 31 and a driving device 32, the driving device 32 is fixedly connected to the frame 1, one end of the auxiliary roller 31 passes through the frame 1 and is connected to the driving device 32, and the other end passes through the frame 1 and is connected to the static electricity removal device, the main roller mechanism 2 includes a main shaft 21 and an adjusting structure 22, and the adjusting structure 22 includes an adjusting driving device 221, a rotating plate 222, a support plate 223 and a placement structure 224, the support plate 223 is fixedly connected to the rotating plate 222, the rotating plate 222 is rotatably connected to the frame 1, the main shaft 21 is fixed to the upper part of the support plate 223 through the placement structure 224, the main shaft 21 is adjacent to the auxiliary roller 31, the adjustment drive device 221 is connected to the support plate 223 and drives the support plate 223 to drive the main shaft 21 to approach or move away from the auxiliary roller 31, the main shaft 21 is used to place the lining paper roll, the auxiliary roller 31 is provided with a plurality of air outlet channels, the air outlet channels face the main shaft 21, the static electricity removal device 4 generates a static electricity removal airflow and transmits it to the lining paper roll through the air outlet channel. The present invention adopts a composite linkage structure of a rotating plate 222-supporting plate 223, and accurately controls the distance between the main roller and the auxiliary roller 31 through adjusting the driving device 221 to adaptively adjust the distance. The rotating plate 222 cooperates with the rotating pair of the frame 1 to enable the support plate 223 to drive the main shaft 21 to move along a linear trajectory, ensuring that during the unwinding process of liner paper rolls with different winding diameters, the contact surface between the auxiliary roller 31 and the material always maintains an optimal pressure distribution, effectively solving the tension fluctuation problem caused by the change of winding diameter in the traditional mechanism, and improving the unwinding stability.

[0031] In addition, the present application integrates the plasma blower and the auxiliary roller 31 into an integrated design, and constructs a directional air outlet channel arranged in a multi-dimensional array inside the auxiliary roller 31, so that the plasma wind forms a uniform laminar flow through the micropores on the surface of the roller body. This structure can effectively increase the effective coverage area of ​​the ion wind and significantly improve the efficiency of static neutralization. At the same time, the rotational motion of the auxiliary roller 31 and the airflow injection form a synergistic effect to form a dynamic cleaning area on the surface of the material. The bipolar ion wind generated by high-voltage electric field ionization can effectively neutralize the static electricity on the surface of the material. The synchronously generated directional airflow can peel off the attached particles, and the treatment process is free of chemical pollution, which meets the requirements of environmentally friendly production. In addition, the present invention integrates the anti-static module and the drive mechanism into the axial space of the roller body while ensuring the functional integrity of the tension roller system through the combined connection layout design of the main shaft 21-auxiliary roller 31. The longitudinal size of the equipment is reduced, and a quick disassembly interface is reserved to facilitate modular replacement during maintenance.

[0032] like Figure 3-Figure 4As shown, the auxiliary roller 31 includes an outer roller 311, a hollow long shaft 312, a connecting short shaft 313, a flexible air outlet sleeve 314, a sealing sleeve 315 and a connector 316. The sealing sleeves 315 are respectively located at both ends of the outer roller 311. The outer roller 311 is provided with a plurality of air outlets 3111. The hollow long shaft 312 passes through the outer roller 311 and the sealing sleeves 315 at both ends are fixedly connected. One end of the hollow long shaft 312 is connected to the driving device 32, and the other end is detachably connected to the connector 316. The head 316 is connected to the static electricity removal device 4, and a plurality of gas distribution ports 3121 are provided on the hollow long shaft 312. The connecting short shaft 313 is arranged inside the outer roller 311, and one end of the connecting short shaft 313 is fixedly connected to the gas distribution port 3121, and the other end faces the gas outlet 3111. The connecting short shaft 313 is connected to the hollow long shaft 312 to form a gas outlet channel, and one end of the connecting short shaft 313 facing the gas outlet 3111 is connected to the flexible gas outlet sleeve 314, and the flexible gas outlet sleeve 314 is arranged at the gas outlet 3111. The present invention adopts a coaxial nested structure of the hollow long shaft 312 and the connecting short shaft 313, and integrates the gas path channel and the mechanical transmission shaft into a whole. One end of the hollow long shaft 312 is connected to the driving device 32, and the other end is quickly connected to the static electricity removal device through a quick-release joint. This modular design significantly reduces the assembly precision requirements while ensuring air tightness. During maintenance, components can be replaced by independent disassembly, avoiding the cumbersome operation of overall disassembly and assembly of the traditional structure. In addition, a flexible air outlet sleeve 314 is provided at the end of the connecting short shaft 313, and the deformation compensation characteristics of the elastic material are used to form a dynamic adaptive seal between the air sleeve and the air outlet 3111 of the outer roller 311. The present application can not only compensate for assembly errors, but also adapt to thermal expansion changes under high-speed rotation, thereby ensuring the long-term stability of air tightness. A branch air path is constructed through the air outlet 3121 of the hollow long shaft 312 and multiple groups of radially distributed connecting short shafts 313 to form a tree-like shunt network. By differentially designing the extension length of the connecting short shaft 313, the air flow resistance of each branch is actively adjusted to achieve balanced distribution of the flow of different air outlets 3111, thereby ensuring the uniformity and stability of the air flow distribution on the roller surface. At the same time, the sealing sleeves 315 at both ends of the outer roller 311 form a dual positioning reference with the hollow long shaft 312, and combined with the damping characteristics of the flexible air outlet sleeve 314, the vibration conduction during high-speed rotation is effectively suppressed. While ensuring the rigidity of the structure, the design absorbs dynamic disturbances through the buffering effect of the flexible unit, significantly improving the running stability of the auxiliary roller 31.

[0033] Further, such as Figure 5 As shown, a plurality of slits 3141 are provided at one end of the flexible air outlet sleeve 314, and the slits 3141 are connected to the connecting short shaft 313. The present invention sets a radial slit 3141 array at the end of the flexible air outlet sleeve 314, and each slit 3141 is precisely aligned with the outlet of the connecting short shaft 313 to form a directional diffusion flow channel, breaking the inertial distribution of the airflow with traditional uniform openings, and realizing efficient diffusion of ion wind.

[0034] like Figure 6 As shown, a connecting groove 3131 is provided at one end of the connecting short shaft 313 facing the air outlet 3111, and the other end of the flexible air outlet sleeve 314 is tightly sleeved outside the connecting groove 3131, and a convex pattern is provided on the side where the connecting groove 3131 and the flexible air outlet sleeve 314 are connected. The present application provides convex patterns in the connecting groove 3131 to further strengthen the connection friction between the connecting groove 3131 and the flexible air outlet sleeve 314 to prevent them from falling off. In addition, the convex patterns of the present application are spiral convex patterns, and the cross-section of the convex patterns is an asymmetric trapezoid (the tilt angle of the front rotation side is 45°, and the tilt angle of the back side is 60°). Through the threaded design, the radial friction force is converted into an axial locking force to adapt to the dynamic load generated by the rotation, prevent micro-wear between the convex patterns and the flexible sleeve, and improve long-term stability.

[0035] Furthermore, the auxiliary roller 31 also includes a dust cover 317, a support ring 3142 is provided on the outer peripheral surface of the gap 3141 of the flexible air outlet sleeve 314, the dust cover 317 is clamped at the air outlet 3111 and is connected to the support ring 3142, and a pry hole 3171 is provided on the dust cover 317. The dust cover 317 of the present invention integrates three different working modes, and the function switching can be achieved through simple operation. Mode 1, when a larger static removal effect is not required, the dust cover 317 can be easily removed by using the pry hole 3171, and the plasma wind is directly output through the flexible air outlet sleeve 314. This method can provide a more conventional static removal effect, and the airflow output is more dispersed. Mode 2, when a larger static removal wind force is required, the dust cover 317 is kept at the air outlet 3111, but the plasma wind is output through the pry hole 3171 on the dust cover 317, and the wind speed is significantly improved by using the narrow tube effect, thereby enhancing the static removal ability. Mode 3: When no processing operation is required, the dust cover 317 is completely in a protective state, tightly connected to the support ring 3142, effectively preventing dust from entering the air outlet 3111 and protecting the internal structure of the equipment from dust pollution. This structure can be flexibly adjusted without replacing the entire equipment or complex structural adjustments, which improves the versatility and adaptability of the equipment and reduces the equipment maintenance cost of the enterprise.

[0036] like Figure 7As shown, the connector 316 includes a connecting sleeve 3161, an inserted flexible shaft 3162, a gas nozzle 3163 and a fixed sealing plate 3164. One end of the connecting sleeve 3161 is sleeved on the outside of the hollow long shaft 312, and the other end is connected to the fixed sealing plate 3164. The inserted flexible shaft 3162 is arranged inside the connecting sleeve 3161. One end of the inserted flexible shaft 3162 is fixedly connected to the fixed sealing plate 3164, and the other end is sealed and inserted into the hollow long shaft 312. One end of the gas nozzle 3163 passes through the connecting sleeve 3161 and is connected to the inserted flexible shaft 3162, and the other end is connected to the static electricity removal device 4. In this application, the connecting sleeve 3161 is used as an outer structure to provide protection and an overall fixed frame for the connector 316. The inserted flexible shaft 3162 is located in the connecting sleeve 3161 and is sealed and connected to the hollow long shaft 312. This nested structure constructs an airway in a limited space, and each component is tightly connected to prevent gas leakage. The air nozzle 3163 is connected to the inserted flexible shaft 3162 to further improve the airway, forming a continuous airflow channel from the plasma blower to the hollow long shaft 312. This structure makes the equipment layout more compact, which is conducive to miniaturized design, and the components are tightly connected and well sealed. Gas leakage and pressure loss can be reduced during plasma wind transmission, ensuring stable static electricity removal effect. Specifically, the outer diameter of the inserted flexible shaft 3162 is smaller than the inner diameter of the hollow long shaft 312, and a conical sealing head is provided at the insertion end for sealing connection with the hollow long shaft 312. The air nozzle 3163 is made of metal, and the connection part with the inserted flexible shaft 3162 can be connected by means of threads or the like. At the same time, the integrated connector 316 design can reduce the number of parts, simplify the assembly process, improve assembly efficiency, reduce manufacturing and assembly costs, and reduce the possibility of assembly errors.

[0037] Furthermore, a sealing convex ring is provided on the outside of one end of the inner flexible shaft 3162 inserted into the hollow long shaft 312, and the sealing convex ring abuts against the inner wall surface of the hollow long shaft 312. The sealing convex ring improves the local sealing without increasing the complexity of the overall structure, thereby improving the performance of the entire connector 316. At the same time, the sealing convex ring has a simple and reliable structure, good compatibility with the existing structure, and can stably play a sealing role during long-term use to ensure the stable operation of the equipment.

[0038] Furthermore, the connecting head 316 also includes a sliding ring 3165 and a positioning piece 3166. A positioning through hole is provided on the connecting sleeve 3161, and the positioning piece 3166 is arranged in the positioning through hole. The sliding ring 3165 is sleeved on the outside of the connecting sleeve 3161 and is slidably connected to the connecting sleeve 3161. A movable hole is provided on the side where the sliding ring 3165 is connected to the connecting sleeve 3161, and a limiting ring groove 3122 is provided at one end of the hollow long axis 312 close to the connecting sleeve 3161.

[0039] When the sliding ring 3165 slides to the point where the positioning perforation is misaligned with the movable hole, one end of the positioning member 3166 is connected to the sliding ring 3165, and the other end passes through the positioning perforation and is connected to the limiting ring groove 3122; when the sliding ring 3165 slides to the point where the positioning perforation is aligned with the movable hole, the positioning member 3166 is separated from the limiting ring groove 3122. The quick-connect structure formed by the sliding ring 3165 and the positioning member 3166 makes the connection and disassembly of the connector 316 and the hollow long shaft 312 simple and quick, without the need for complex tools, saving time and labor costs, and improving production efficiency. In addition, the sliding ring 3165 is fixed by bolts, and the positioning member 3166 is a steel ball. The spring failure that is prone to occur in traditional quick connectors and the long rotation of the hollow long shaft 312 to avoid wear problems improve the durability of the connector 316, reduce the maintenance and replacement frequency, and ensure the long-term stable operation of the equipment.

[0040] like Figure 8 As shown, the placement structure 224 includes a first fixing frame 2241, a second fixing frame 2242 and an adjustment handle 2243. The first fixing frame is fixedly connected to the frame 1, the second fixing frame 2242 is rotatably connected to the frame 1, the adjustment handle 2243 is rotatably connected to the first fixing frame 2241, and the second fixing frame 2242 is provided with a locking opening.

[0041] When the second fixing frame 2242 is rotated to the first state, the second fixing frame 2242 and the first fixing frame 2241 form a placement space, the adjustment handle 2243 abuts against the locking port, and bearings are fixed at both ends of the main shaft 21, and the bearings are fixed at the placement space; when the second fixing frame 2242 is rotated to the second state, the second fixing frame 2242 is separated from the first fixing frame 2241, the adjustment handle 2243 is separated from the second fixing frame 2242, and the main shaft 21 can be detached and separated. The present invention uses the adjustment handle 2243 to achieve the fixation of the second fixing frame 2242 in a specific state. The operation of the adjustment handle 2243 is relatively simple. By rotating the adjustment handle 2243, the abutment or separation with the locking port can be achieved, thereby fixing the second fixing frame 2242 in a state of forming a placement space with the first fixing frame 2241. When the main shaft 21 needs to be disassembled, the adjustment handle 2243 is also operated to separate it from the locking port, and then the second fixing frame 2242 is rotated. This simple operation process reduces the technical requirements for operators and also reduces the time cost during the operation.

[0042] like Fig. 9As shown, the unwinding mechanism also includes an elastic auxiliary wheel mechanism 5, which includes a fixed seat 51, a support plate 52, an adjusting gas rod 53 and an auxiliary pressure wheel 54. The fixed seat 51 is fixedly connected to the frame 1, one end of the support plate 52 is rotatably connected to the fixed seat 51, and the other end is connected to the side of the auxiliary pressure wheel 54 close to the main shaft 21, and the auxiliary pressure wheel 54 faces the main shaft 21. One end of the adjusting gas rod 53 is fixedly connected to the fixed seat 51, and the other end is connected to the side of the support plate 52 away from the auxiliary pressure wheel 54. The adjusting gas rod 53 drives the support plate 52 to drive the auxiliary pressure wheel 54 close to the main shaft 21. In the traditional unwinding process, the loose roll will increase the physical friction between the film rolls, and this friction is an important source of static electricity. The elastic auxiliary wheel mechanism 5 accurately controls the pressing force of the auxiliary pressure wheel 54 on the inner lining paper roll by adjusting the gas rod 53, so that the roll maintains a stable winding state, fundamentally reducing the possibility of static electricity generated by friction. The method of reducing static electricity generation by controlling the looseness of the lining paper roll is more direct, which reduces the impact of static electricity on the unwinding process and product quality to a certain extent, and ensures that the lining paper roll is neither loose nor damaged during the unwinding process. In addition, the auxiliary pressure wheel 54 is made of rubber, and its surface is provided with anti-skid patterns. When the regulating gas rod 53 is started, the auxiliary pressure wheel 54 will continue to drive the pressure on the lining paper roll, and the softness of the rubber material can better fit the surface of the roll, and compared with other hard materials, it can reduce the accumulation of static electricity caused by poor contact. Moreover, the anti-skid patterns further optimize the contact state while ensuring the pressing effect, making the distribution of charges more uniform and reducing the static electricity caused by local charge concentration. The tension auxiliary wheel mechanism 5 can work in conjunction with other existing static electricity removal methods (such as ion fan static electricity removal, etc.). When static electricity removal equipment such as ion fans perform static electricity removal operations on the unwinding area, since the tension auxiliary wheel mechanism 5 has reduced the generation of static electricity from the source, the workload of these static electricity removal equipment is reduced, the overall static electricity removal efficiency is improved, and the static electricity removal cost is reduced. What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application.
