The main roller mechanism is used for placing the inner liner paper reel, the unwind assist roller mechanism is used to assist the main roller mechanism in unwinding, and the anti-static device is used for anti-static treatment of the inner liner paper. Through the integrated design of the plasma blower and the assist roller and the design of the tension assist wheel mechanism, the present invention realizes the anti-static treatment during the unwinding process of the inner liner paper reel. In the integrated design of the plasma blower and the assist roller, a multi-dimensional array type directional air outlet channel is constructed inside the assist roller, so that the plasma wind forms a uniform laminar flow through the roller body air duct.

Cooperating with the plasma anti-static method, the overall anti-static efficiency is improved and the cost is reduced.

Description

Technical Field

[0001] The present invention relates to the technical field of inner lining paper, and particularly to an unwinding mechanism for inner lining paper compounding. Background Art

[0002] The aluminum foil paper for cigarettes is composed of aluminum foil and inner lining paper compounded with an adhesive. Its main function is to wrap the cigarettes in the cigarette case, create a suitable storage environment for the cigarettes, maintain the moisture of the cigarettes, and delay the loss of the flavor components of the cigarettes. With the development of the tobacco industry and the improvement of the scientific and technological level, the requirements for the use of aluminum foil paper by cigarette enterprises are constantly increasing. The inner lining paper is an important material for cigarette packaging, playing an important role in moisture-proof and flavor-preserving, and can ensure the stable suction quality of cigarettes during storage. Due to its good barrier properties, composite aluminum foil inner lining paper and vacuum aluminized inner lining paper are widely used at home and abroad.

[0003] However, there are many problems in the prior art. When printing the inner lining paper, it is unwound by an unwinding mechanism, and then wound up after being printed by a printing device. The unwinding mechanism sleevs the inner lining paper reel on the unwinding shaft. During unwinding, due to the interaction of various physical factors, static electricity will be generated on the inner lining paper, and the static electricity will adsorb the surrounding adhesives onto the surface of the inner lining paper. Once these adhesives adhere, they are very difficult to remove, causing great obstacles to the unwinding of the inner lining paper and seriously interfering with the smooth progress of the entire printing process. Therefore, there is an urgent need for an unwinding mechanism for inner lining paper printing to solve these problems. Summary of the Invention

[0024] The beneficial effects of the present invention:

[0025] 1. The present invention innovatively adopts a composite linkage mechanism of a rotating plate - support plate. By adjusting the driving device, it controls the rotation of the rotating plate around the frame, drives the support plate to drive the main roller to move along a linear trajectory, and dynamically matches the change in the winding diameter. This structure enables precise self - adaptive adjustment of the distance between the main roller and the auxiliary roller, ensuring a constant contact pressure between different - specification inner - liner paper reels and the auxiliary roller during unwinding, eliminating the tension fluctuation caused by the difference in winding diameter in the traditional mechanism, and significantly improving the stability of unwinding.

[0026] 2. Through the integrated design of a plasma blower and an auxiliary roller, the present invention constructs a multi - dimensional array - type directional air - outlet channel inside the auxiliary roller, enabling the plasma wind to form a uniform laminar flow through the roller body air duct, and significantly improving the uniformity of ion coverage. When the auxiliary roller rotates, it cooperates with the air - flow jet to form a dynamic cleaning area on the material surface: while the bipolar ion wind efficiently neutralizes static electricity, the directional air flow synchronously peels off attached particles, and the whole process is a physical treatment without chemical pollution, meeting the requirements of environmental - friendly production.

[0027] 3. Through the combined connection layout design of the main shaft - auxiliary roller, on the premise of ensuring the functional integrity of the tension roller system, the static - elimination module and the driving mechanism are integrated into the axial space of the roller body, reducing the longitudinal dimension of the equipment. At the same time, a quick - disassembly and installation interface is reserved, facilitating modular replacement during maintenance.

[0028] 4. By the pressing force of the loose - tight auxiliary wheel mechanism on the inner - liner paper reel, the reel is kept in a stable winding state, fundamentally reducing the possibility of generating static electricity due to friction. Working in coordination with other existing static - elimination methods, the working load of the static - elimination equipment is reduced, thereby improving the overall static - elimination efficiency and reducing the static - elimination cost.

Detailed implementation manners

[0040] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0041] As shown in Figure 1 - Figure 2As shown in the figure, an unwinding mechanism for inner liner paper compounding includes a frame 1, a main roller mechanism 2, an unwinding auxiliary roller 31 mechanism, and an electrostatic elimination device. The main roller mechanism 2 is used to place the inner liner paper reel. The unwinding auxiliary roller 31 mechanism is used to assist the main roller mechanism 2 in unwinding. The electrostatic elimination device is used to perform electrostatic elimination treatment on the inner liner paper. The unwinding 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 electrostatic elimination device. The main roller mechanism 2 includes a main shaft 21 and an adjusting structure 22. The adjusting structure 22 includes an adjusting driving device 221, a rotating plate 222, a supporting plate 223, and a placing structure 224. The supporting 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 on the upper part of the supporting plate 223 through the placing structure 224. The main shaft 21 is arranged adjacent to the auxiliary roller 31. The adjusting driving device 221 is connected to the supporting plate 223 and drives the supporting 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 inner liner paper reel. The auxiliary roller 31 is provided with a plurality of air outlet channels, and the air outlet channels face the main shaft 21. The electrostatic elimination device 4 generates an electrostatic elimination air flow and transmits it to the inner liner paper reel through the air outlet channels. The present invention adopts a composite linkage structure of the rotating plate 222 - supporting plate 223, and precisely controls the distance between the main roller and the auxiliary roller 31 to be adaptively adjusted through the adjusting driving device 221. Through the cooperation of the rotating pair of the rotating plate 222 and the frame 1, the supporting plate 223 drives the main shaft 21 to move along a linear trajectory, ensuring that during the unwinding process of inner liner paper reels with different diameters, the contact surface between the auxiliary roller 31 and the material always maintains the best pressure distribution, effectively solving the problem of tension fluctuation caused by the change of the reel diameter in the traditional mechanism and improving the unwinding stability.

[0042] In addition, in this application, the plasma blower and the auxiliary roller 31 are integrally designed, and a multi-dimensional array arrangement of directional air outlet channels is constructed 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 electrostatic neutralization efficiency. At the same time, the rotational movement of the auxiliary roller 31 and the air flow jet form a synergistic effect, forming a dynamic cleaning area on the material surface. The bipolar ion wind generated by the ionization of the high-voltage electric field can efficiently neutralize the static electricity on the material surface, and the simultaneously generated directional air flow can peel off the attached particles, and the treatment process has no chemical pollution, meeting the requirements of environmental protection production. In addition, through the combined connection layout design of the main shaft 21 - auxiliary roller 31, on the premise of ensuring the functional integrity of the tension roller system, the electrostatic elimination module and the driving mechanism are integrated into the axial space of the roller body, reducing the longitudinal dimension of the equipment, and at the same time reserving a quick disassembly and assembly interface for modular replacement during maintenance.

[0043] As Figure 3 - Figure 4As shown in the figure, the auxiliary roller 31 includes an outer roller barrel 311, a hollow long shaft 312, a connecting short shaft 313, a flexible air outlet sleeve 314, a shaft sealing sleeve 315 and a connector 316. The shaft sealing sleeves 315 are respectively located at both ends of the outer roller barrel 311. The outer roller barrel 311 is provided with a plurality of air outlet holes 3111. The hollow long shaft 312 passes through the outer roller barrel 311 and is fixedly connected to the shaft sealing sleeves 315 at both ends respectively. 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 connector 316 is communicated with the static eliminator 4. The hollow long shaft 312 is provided with a plurality of air distribution holes 3121. The connecting short shaft 313 is arranged inside the outer roller barrel 311. One end of the connecting short shaft 313 is fixedly connected to the air distribution hole 3121, and the other end faces the air outlet hole 3111. The connecting short shaft 313 and the hollow long shaft 312 are connected to form an air outlet channel. The end of the connecting short shaft 313 facing the air outlet hole 3111 is connected to the flexible air outlet sleeve 314. The flexible air outlet sleeve 314 is arranged at the air outlet hole 3111. The present invention adopts a coaxial nested structure of the hollow long shaft 312 and the connecting short shaft 313, integrates the air 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 docked with the static eliminator through a quick-release joint. This modular design not only ensures airtightness, but also significantly reduces the requirements for assembly accuracy. During maintenance, components can be independently disassembled and replaced, avoiding the cumbersome operation of overall disassembly and assembly of the traditional structure. In addition, a flexible air outlet sleeve 314 is arranged at the end of the connecting short shaft 313. By using the deformation compensation characteristic of the elastic material, a dynamic adaptive seal is formed between the air outlet sleeve and the air outlet hole 3111 of the outer roller barrel 311. This application can not only compensate for assembly errors, but also adapt to thermal expansion changes under high-speed rotation, ensuring the long-term stability of airtightness. A branch air path is constructed through the air distribution holes 3121 of the hollow long shaft 312 and multiple groups of radially distributed connecting short shafts 313 to form a tree-shaped shunt network. By differentially designing the extension lengths of the connecting short shafts 313, the air flow resistance of each branch is actively adjusted to achieve balanced distribution of the flow rates of different air outlet holes 3111, thereby ensuring the uniformity and stability of the air flow distribution on the roller surface. At the same time, the shaft sealing sleeves 315 at both ends of the outer roller barrel 311 and the hollow long shaft 312 form a double positioning reference. Combining with the damping characteristic of the flexible air outlet sleeve 314, the vibration conduction during high-speed rotation is effectively suppressed. While ensuring the structural rigidity, this design absorbs dynamic disturbances through the buffering effect of the flexible unit, significantly improving the running smoothness of the auxiliary roller 31.

[0044] Further, as Figure 5 shown, one end of the flexible air outlet sleeve 314 is provided with a plurality of slits 3141. The slits 3141 are communicated with the connecting short shaft 313. The present invention arranges an array of radial slits 3141 at the end of the flexible air outlet sleeve 314. Each slit 3141 is accurately aligned with the outlet of the connecting short shaft 313 to form a directional dispersion flow channel, breaking the inertial distribution of the air flow with traditional uniform openings and realizing efficient dispersion of the ion wind.

[0045] As shown Figure 6 in the figure, one end of the connecting short shaft 313 facing the air outlet 3111 is provided with a connecting groove 3131. The other end of the flexible air outlet sleeve 314 is tightly sleeved outside the connecting groove 3131, and the surface of the connecting groove 3131 connected to the flexible air outlet sleeve 314 is provided with convex stripes. In the present application, convex stripes are arranged in the connecting groove 3131 to further strengthen the connection friction force between the connecting groove 3131 and the flexible air outlet sleeve 314 and prevent detachment. In addition, the convex stripes in the present application are spiral convex stripes, and the cross-section of the convex stripes is an asymmetric trapezoid (the inclination angle on the side facing the rotation is 45°, and the inclination angle on 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 rotation, prevent fretting wear between the convex stripes and the flexible sleeve, and improve the long-term stability.

[0046] Furthermore, the auxiliary roller 31 further includes a dust-proof cover 317. A support ring 3142 is arranged on the outer peripheral surface of the gap 3141 of the flexible air outlet sleeve 314. The dust-proof cover 317 is clamped at the air outlet 3111 and abuts against the support ring 3142. The dust-proof cover 317 is provided with a pry hole 3171. The dust-proof cover 317 of the present invention combines three different working modes, and the function can be switched through simple operations. Mode 1: When a large anti-static effect is not required, the dust-proof cover 317 can be easily removed by using the pry hole 3171. At this time, the plasma wind is directly output through the flexible air outlet sleeve 314. This method can provide a relatively conventional anti-static effect, and the air flow output is relatively dispersed. Mode 2: When a large anti-static wind force is required, the dust-proof cover 317 is kept at the air outlet 3111, but the plasma wind is output through the pry hole 3171 on the dust-proof cover 317. By using the Venturi effect, the wind speed is significantly increased, enhancing the anti-static ability. Mode 3: When processing operations are not required, the dust-proof cover 317 is completely in a protective state, tightly abuts against the support ring 3142, effectively preventing dust from entering the inside of the air outlet 3111, and protecting the internal structure of the device from dust pollution. This structure can be flexibly adjusted without replacing the entire device or complex structural adjustments, improving the versatility and adaptability of the device and reducing the equipment maintenance cost of the enterprise.

[0047] As shown Figure 7As shown in the figure, the connector 316 includes a connecting outer sleeve 3161, an inserted flexible shaft 3162, a nozzle 3163, and a fixed sealing plate 3164. One end of the connecting outer sleeve 3161 is sleeved outside 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 outer sleeve 3161. One end of the inserted flexible shaft 3162 is fixedly connected to the fixed sealing plate 3164, and the other end is hermetically inserted into the hollow long shaft 312. One end of the nozzle 3163 passes through the connecting outer sleeve 3161 and is connected to the inserted flexible shaft 3162, and the other end is connected to the static eliminator 4. In this application, the connecting outer sleeve 3161 serves as an outer structure, providing protection and an overall fixing framework for the connector 316. The inserted flexible shaft 3162 is located inside the connecting outer sleeve 3161 and is hermetically connected to the hollow long shaft 312. This nested structure constructs an air passage in a limited space, and the components are tightly connected to prevent gas leakage. The nozzle 3163 is connected to the inserted flexible shaft 3162 to further improve the air passage, forming a continuous air flow channel from the plasma blower to the hollow long shaft 312. This structure makes the equipment layout more compact, conducive to miniaturized design, and the components are tightly connected and well-sealed. When the plasma wind is transported, gas leakage and pressure loss can be reduced, ensuring stable static elimination effect. Specifically, the outer diameter of the inserted flexible shaft 3162 is smaller than the inner diameter of the hollow long shaft 312, and the inserted end is provided with a conical sealing head for hermetically connecting with the hollow long shaft 312. The 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 design of the connector 316 can reduce the number of components, simplify the assembly process, improve the assembly efficiency, reduce the manufacturing and assembly costs, and reduce the possibility of assembly errors.

[0048] Furthermore, a sealing convex ring is provided outside one end of the inserted 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. This sealing convex ring improves the local sealing performance 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 structure is simple and reliable, has good compatibility with the existing structure, and can stably play a sealing role during long-term use, ensuring the stable operation of the equipment.

[0049] Still further, the connector 316 further includes a sliding ring 3165 and a positioning member 3166. The connecting outer sleeve 3161 is provided with a positioning through hole, the positioning member 3166 is arranged in the positioning through hole, the sliding ring 3165 is sleeved outside the connecting outer sleeve 3161 and is slidably connected to the connecting outer sleeve 3161. One surface of the sliding ring 3165 connected to the connecting outer sleeve 3161 is provided with a movable hole, and a limiting ring groove 3122 is provided at one end of the hollow long shaft 312 close to the connecting outer sleeve 3161.

[0050] When the sliding ring 3165 slides to a position where the positioning perforation and the movable hole are misaligned, one end of the positioning member 3166 abuts and connects with the sliding ring 3165, and the other end passes through the positioning perforation and abuts and connects with the limiting ring groove 3122; when the sliding ring 3165 slides to a position where the positioning perforation and the movable hole are aligned, the positioning member 3166 separates from the limiting ring groove 3122. The quick-connection structure formed by the sliding ring 3165 and the positioning member 3166 makes the connection and disassembly operations of the connector 316 and the hollow long shaft 312 simple and fast, without the need for complex tools, saving time and labor costs and improving production efficiency. In addition, the sliding ring 3165 of the present invention is fixed by bolts, and the positioning member 3166 is a steel ball, which solves the problems of spring failure prone to occur in traditional quick connectors and the need for the hollow long shaft 312 to rotate for a long time to avoid wear, improves the durability of the connector 316, reduces the maintenance and replacement frequency, and ensures the long-term stable operation of the equipment.

[0051] As Figure 8 shown, the placement structure 224 includes a first fixing frame 2241, a second fixing frame 2242 and an adjusting handle 2243. The first fixing frame is fixedly connected to the machine frame 1, the second fixing frame 2242 is rotatably connected to the machine frame 1, the adjusting handle 2243 is rotatably connected to the first fixing frame 2241, and a locking port is provided on the second fixing frame 2242.

[0052] When the second fixing frame 2242 rotates to the first state, the second fixing frame 2242 and the first fixing frame 2241 form a placement space, the adjusting handle 2243 abuts against the locking port, 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 rotates to the second state, the second fixing frame 2242 separates from the first fixing frame 2241, the adjusting handle 2243 separates from the second fixing frame 2242, and the main shaft 21 can be detachably separated. The present invention uses the adjusting handle 2243 to fix the second fixing frame 2242 in a specific state. The operation of the adjusting handle 2243 is relatively simple. By rotating the adjusting handle 2243, it can abut against or separate from the locking port, so as to fix the second fixing frame 2242 in the state of forming a placement space with the first fixing frame 2241. When the main shaft 21 needs to be disassembled, the adjusting 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 the operator and also reduces the time cost during the operation.

[0053] As Figure 9As shown in the figure, the unwinding mechanism further includes a tension assisting wheel mechanism 5. The tension assisting wheel mechanism 5 includes a fixed seat 51, a support plate 52, an adjusting air cylinder 53 and an auxiliary pressing 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 pressing wheel 54 close to the main shaft 21. The auxiliary pressing wheel 54 faces the main shaft 21. One end of the adjusting air cylinder 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 pressing wheel 54. The adjusting air cylinder 53 drives the support plate 52 to drive the auxiliary pressing wheel 54 to approach the main shaft 21. During the traditional unwinding process, the looseness of the reel will increase the physical friction between the film reels, and this friction is an important source of static electricity generation. The tension assisting wheel mechanism 5 precisely controls the pressing force of the auxiliary pressing wheel 54 on the inner liner paper reel through the adjusting air cylinder 53, so that the reel maintains a stable winding state, fundamentally reducing the possibility of static electricity generation due to friction. The method of reducing static electricity generation by controlling the looseness of the inner liner paper reel is more direct, and to a certain extent, reduces the impact of static electricity on the unwinding process and product quality, ensuring that the inner liner paper reel is neither loose nor damaged during the unwinding process. In addition, the auxiliary pressing wheel 54 is made of rubber, and its surface is provided with anti-slip patterns. When the adjusting air cylinder 53 is started, it will continuously drive the auxiliary pressing wheel 54 to generate a pressing force on the inner liner paper reel. The softness of the rubber material can better fit the surface of the reel. Compared with other hard materials, it can reduce the static electricity accumulation caused by poor contact. Moreover, the anti-slip patterns further optimize the contact state while ensuring the pressing effect, making the distribution of charges more uniform and reducing the static electricity phenomenon caused by local charge concentration. The tension assisting wheel mechanism 5 can work in cooperation with other existing anti-static methods (such as anti-static by ion blowers, etc.). When anti-static equipment such as ion blowers performs anti-static operations on the unwinding area, since the tension assisting wheel mechanism 5 has reduced the generation of static electricity from the source, the working load of these anti-static equipment is reduced, improving the overall anti-static efficiency and reducing the anti-static cost.
