[0044] The cigarette rod packing device adopting the pressing and pushing mechanism of the embodiment will be described below, so that the pressing and pushing mechanism of the embodiment can be better understood.

[0045] As shown in Figures 3 to 14 The cigarette rod packing device for tobacco logistics adopting the pressing and pushing mechanism of the embodiment includes a rack 9, a film guiding mechanism 11, the above-mentioned pressing and pushing mechanism, an upper cutter assembly 14, a lower cutter assembly 13, an output table 2, a film placing roller 8, a counterweight film passing assembly 10 and a conveyor 1.

[0046] The pressing and pushing mechanism of the embodiment is arranged at the upper end of the rack 9, and the horizontal guide rail 3.3 of the pressing and pushing mechanism is fixed to the inner side of the upper end of the rack 9.

[0047] The middle part of the rack 9 is provided with a cigarette rod staying space 12, the translation assembly 3 of the pressing and pushing mechanism is arranged above the cigarette rod staying space 12, one end of the conveyor 1 is arranged in the cigarette rod staying space 12, and the conveying belt of the conveyor 1 is provided with a partition plate 1.1, which divides the space on the conveying belt into a plurality of cigarette rod stacking positions 1.2. The cigarette rod to be packed is stacked in the cigarette rod stacking position 1.2, and is conveyed to the cigarette rod staying space 12 by the conveyor 1 for packing. The conveyor 1 of the embodiment is a chain plate conveyor.

[0048] As shown in Figure 6 and Figure 7As shown, the film unwinding roller 8 and the counterweight film passing assembly 10 are arranged on the two side edges of the cigarette staying space 12, and the counterweight film passing assembly 10 is located between the film unwinding roller 8 and the conveyor 1. The structure of the film unwinding roller 8 can adopt the unpowered film feeding mechanism provided in the Chinese patent with the application number 202021433095.3, or can adopt the conventional mechanism in which the film unwinding roller is driven to rotate by a film unwinding motor. In use, the film roll 7 is mounted on the film unwinding roller 8 on the two sides, and the packaging films 7.1 of the film rolls 7 on the two sides are connected together and span over the cigarette staying space 12 from above.

[0049] As shown, Figure 9 The counterweight film passing assembly 10 is provided with two corresponding limiting frames 10.3 and a counterweight rod 10.1, the limiting frames 10.3 are fixedly connected to the rack 9, the two limiting frames 10.3 are respectively provided with vertical long limiting holes 10.4, the counterweight rod 10.1 is located between the two limiting frames 10.3, the two ends of the counterweight rod 10.1 are respectively matched with the long limiting holes 10.4, and the counterweight rod 10.1 can freely move up and down. The counterweight film passing assembly is also provided with two fixed guide rollers 10.2, the two fixed guide rollers 10.2 are respectively installed between the two limiting frames 10.3 and located on the two sides above the long limiting holes 10.4. Figure 6 As shown, in use, the packaging films 7.1 on the two sides will first pass over the fixed guide rollers 10.2 close to the film roll 7 from above, then pass under the counterweight rod 10.1, and finally pass over the fixed guide rollers 10.2 away from the film roll 7 from above. During use, the counterweight rod 10.1 applies its own gravity to the packaging film 7.1, the counterweight rod 10.1 can keep the packaging film 7.1 under a certain tension, which can prevent the packaging film 7.1 from sagging due to the rotational inertia of the film roll 7, and the packaging film 7.1 kept under a certain tension can better ensure the tightness of the packaging.

[0050] As shown, Figure 6 and Figure 7 The film guide mechanisms 11 are arranged on the two side edges of the cigarette staying space 12, and the packaging films 7.1 spanning over the cigarette staying space 12 are simultaneously lifted and lowered by the film guide mechanisms 11 on the two side edges during use. Figure 8 As shown, the film guide mechanism includes a second lifting assembly, an upper guide roller 11.3 and a lower guide roller 11.4. The second lifting assembly includes a second lifting cylinder 11.1 and a second lifting frame 11.2, the second lifting cylinder 11.1 is vertically upwardly installed on the two side edges of the cigarette staying space 12, and the second lifting frame 11.2 is connected to the upper end of the second lifting cylinder 11.1 and moves up and down driven by the second lifting cylinder 11.1. The upper guide roller 11.3 and the lower guide roller 11.4 are respectively horizontally arranged on the upper edge and the lower edge of the second lifting frame 11.2 of the second lifting assembly. Figure 6As shown, the packaging film 7.1 is used to pass under the lower guide roller 11.4 and over the upper guide roller 11.3. When the second lifting cylinder 11.1 drives the second lifting frame 11.2 to rise, the packaging film 7.1 across the cigarette resting space 12 is lifted. During the rising process, the packaging film 7.1 is naturally tightened. When the second lifting cylinder 11.1 drives the second lifting frame 11.2 to descend, the packaging film 7.1 covers the cartons of cigarettes resting in the cigarette resting space 12, and the lower guide roller 11.4 pulls the packaging film 7.1 downward, so that the packaging is more compact.

[0051] As shown in Figure 6 The output table 2 is arranged at one side of the cigarette resting space 12 and above the film placing roller 8 at the same side. The output table 2 uses a conveying belt to convey the packaged cartons of cigarettes outward. The upper conveying surface of the output table 2 is flush with the upper conveying surface of the conveying machine 1.

[0052] The upper knife assembly 14 of the present embodiment is arranged at the lower edge of the first lifting frame 6.1 and below the push plate 5. The upper knife assembly 14 includes an upper knife seat 14.1 and two upper pressing strips 14.2. The upper knife seat 14.1 is made of metal and can conduct heat. The upper knife seat 14.1 is fixed at the lower edge of the first lifting frame 6.1. An upper heating pipe 14.5 is arranged in the upper knife seat 14.1. Two parallel clamping grooves are arranged at the lower surface of the upper knife seat 14.1, and a concave cutting groove 14.3 is arranged between the two clamping grooves. The upper pressing strips 14.2 are made of foamed silica gel and have a buffering effect. The upper surface of the upper pressing strips 14.2 is provided with clamping blocks 14.4, which are clamped into the clamping grooves, so that the upper pressing strips 14.2 are fixed at the lower surface of the upper knife seat 14.1.

[0053] The lower knife assembly 13 is arranged on the mounting platform 13.6 of the input end of the output table, as shown in Figures 10 to 14As shown, the lower cutter assembly 13 includes two lower cutter seats 13.3, two heating wires 13.8, a Teflon film 13.2, a cutter 13.10 and a third lifting assembly. The two lower cutter seats 13.3 are fixedly installed side by side on the mounting platform 13.6 at the input end of the output table, and the lower cutter seat 13.3 is provided with a lower heating pipe 13.9. A groove 13.33 is provided on the upper surface of the lower cutter seat 13.3, and the heating wire 13.8 is embedded in the groove 13.11, so that the heating wire and the lower cutter seat have better heat transfer, and the temperature during welding is more stable and uniform. Tensioning assemblies 15 are respectively arranged at both ends of the lower cutter seat 13.3, and the tensioning assemblies 15 are connected with the end portions of the heating wire 13.8. The tensioning assemblies 15 always keep the heating wire 13.8 taut, so that the heating wire 13.8 remains in a flat state, and the heating wire 13.8 can better adhere to and more fully contact the packaging film during welding, thereby better ensuring the welding quality and improving the packaging quality. The surface of the lower cutter seat 13.3 is provided with a Teflon film 13.2, and the Teflon film 13.2 covers the upper surface of the heating wire 13.8, so that the heating wire 13.8 does not directly contact the packaging film during welding. The isolation of the Teflon film 13.2 prevents the packaging film from adhering to the lower cutter seat 13.3 and the heating wire 13.8.

[0054] The groove 13.11 on the lower cutter seat 13.3 near the output table 2 is arranged near the edge of the output table 2 (the lower cutter seat 13.3 on the right side of the middle) Figure 12 , so that the heating wire 13.8 on the lower cutter seat 13.3 near the output table 2 is closer to the output table 2, and the welding position during packaging is closer to the packaged cigarette rod.

[0055] During use, the upper cutter seat 14.1 and the lower cutter seat 13.3 can always be kept at a certain low temperature by the upper heating pipe 14.5 and the lower heating pipe 13.9, i.e., the upper cutter seat 14.1 and the lower cutter seat 13.3 have heat tracing. Of course, the temperature is a relatively low temperature, and contact with the packaging film or the cigarette rod will not cause the outer packaging of the packaging film or the cigarette rod to be scalded. The heat tracing is generated to make the heating during subsequent welding more rapid and stable. The heating wire 138 is installed in an embedded manner on the lower cutter seat 13.3 with heat tracing, so that the temperature during welding is more stable and uniform.

[0056] It can be seen that the heating tube only functions to generate heat tracing, and in use, the heating tube provides heat tracing energy for the upper and lower knife assemblies to eliminate the influence of external temperature or operation waiting, etc. The upper and lower knife assemblies are kept in a low temperature state when the packaging film is not being welded, and even if the packaging film or the stick of cigarettes touches it, it will not be scalded, even if the stick of cigarettes is damaged, and it will not cause the packaging film to stick to the upper and lower knife assemblies. It only generates high temperature in a short time through the heating wire 13.8 when welding is needed.

[0057] As shown in Figure 13 and Figure 14 , the tensioning assembly 15 of the present embodiment includes a fixed seat 15.2, a pull plate 15.1, and a spring 15.5. The fixed seat 15.2 is fixed to the mounting platform 13.6 of the input end of the output table and is close to the end face of the lower knife seat 13.3. The lower end of the pull plate 15.1 is rotationally connected to the end of the fixed seat 15.2 away from the lower knife seat 13.3 through a pin shaft 15.4. The spring 15.5 is sleeved on the pin shaft 15.4, one end of the spring 15.5 is pressed against the upper surface of the fixed seat 15.2, and the other end is pressed against the inner side surface of the pull plate 15.1. The spring 15.5 provides a force to keep the pull plate 15.1 turned outward. A pull hook 15.3 is provided at the upper end of the pull plate 15.1, and a pull ring 13.7 is provided at the end of the heating wire 13.8. The pull hook 15.3 is hooked on the pull ring 13.7, thereby tensioning the heating wire 13.8. The two ends of the lower knife assembly of the present embodiment are provided with end covers 13.5, and the position of the tensioning assembly 15 is covered by the end covers 13.5.

[0058] A cutter installation groove 13.4 is provided between the two lower knife seats 13.3, and a cutter 13.10 is installed in the cutter installation groove 13.4. The third lifting assembly includes a third lifting cylinder 13.1, which is installed vertically upward below the cutter installation groove 13.4. The lower end of the cutter 13.10 is connected to the upper end of the third lifting cylinder 13.1, and the cutter 13.10 is driven to lift by the third lifting cylinder 13.1 to achieve cutting of the packaging film 7.1.

[0059] The use process of the stick of cigarettes packaging equipment of the present embodiment is as follows:

[0060] Before use, as shown in Figure 6As shown, the film roll 7 is installed on the film roll mounting roller 8, the film roll 7 is wound around the counterweight film passing assembly 10 and the film guide mechanism 11, and the packaging film 7.1 on both sides of the film roll 7 is welded together. In the initial state, the second lifting frame 11.2 of the film guide mechanism 11 is in the state of being lifted to the high position, the packaging film 7.1 above the conveyor 1 is lifted upward, and the packaging film 7.1 does not hinder the operation of the conveyor 1 and the feeding of the carton cigarette. At the same time, the upper heating tube 14.5 and the lower heating tube 13.9 are always kept in the state of heating, so that the upper cutter assembly and the lower cutter assembly are always kept in a certain low temperature state.

[0061] The next packaging process is as follows:

[0062] 1. The carton cigarettes 16 neatly stacked in the carton cigarette stacking position 1.2 are conveyed to the carton cigarette stopping space 12 by the conveyor 1 and stopped, at this time, the carton cigarettes 16 stacked in the carton cigarette stacking position 1.2 are just below the packaging film 7.1 which is lifted.

[0063] 2. The second lifting frame 11.2 of the film guide mechanism 11 is driven to descend, the packaging film 7.1 is lowered and wrapped around the carton cigarettes 16, and in this process, the lower guide roller 11.4 pulls the packaging film 7.1 downward, so that the packaging film 7.1 can be wrapped more tightly around the carton cigarettes 16. When the second lifting frame 11.2 is lowered to the position, the upper surface of the upper guide roller 11.3 is basically flush with the upper conveying surface of the conveyor 1.

[0064] 3. The first lifting frame 6.1 of the pressing and conveying mechanism is lowered, which drives the push plate 5 and the upper cutter assembly 14 to descend together, and the pressing plate 4 also descends at the same time. In the descending process, the pressing plate 4 first presses against the upper surface of the carton cigarettes 16, and then the first lifting frame 6.1 continues to descend, the first limiting plate 6.2 is separated from the second limiting plate 4.2, and the pressing plate 4 is pressed against the carton cigarettes 16 by its own gravity. When the first lifting frame 6.1 is lowered to the position, the lower surface of the upper cutter assembly 14 is only a small distance away from the upper conveying surface of the conveyor 1, and the preferred distance is 5 mm. At this time, as shown in the figure. Figure 15

[0065] 4. The translation assembly 3 of the pressing and conveying mechanism is translated to the side where the output table 2 is located, and the carton cigarettes 16 wrapped with the packaging film 7.1 are pushed to the output table 2 by the push plate 5. In the pushing process, the packaging film 7.1 is pulled, so that the packaging film 7.1 is wrapped more tightly around the carton cigarettes 16, and finally the carton cigarettes 16 are completely pushed onto the output table. At this time, the upper cutter assembly 14 is aligned with the lower cutter assembly 13, that is, the upper pressing strip 14.2 is aligned with the lower cutter seat 13.3, the cutting knife 13.10 is aligned with the cutting groove 14.3, and the positions of the upper cutter assembly 14 and the lower cutter assembly 13 are close to the carton cigarettes to be packaged.

[0066] ​5. The first lifting frame 6.1 of the pressing mechanism descends again, causing the upper knife assembly 14 and the lower knife assembly 13 to close vertically. The upper pressure strip 14.2 of the upper knife assembly 14 presses onto the lower knife seat 13.3. The upper pressure strip 14.2, made of foamed silicone material, provides cushioning. The packaging film 7.1 will be pressed between the upper knife assembly 14 and the lower knife assembly 13. At this time, if... Figure 16 As shown. Then the heating wire 13.8 heats up instantly, and the upper and lower layers of packaging film 7.1 at the positions of the two heating wires 13.8 are fused together. After that, the third lifting component drives the cutter 13.10 to rise and cut the packaging film 7.1 between the two fused positions.

[0067] 6. Simultaneously, the film guiding mechanism 11 drives its second lifting frame 11.2 to rise, lifting the packaging film 7.1 again. The conveyor 1 transports the neatly stacked cartons of cigarettes 16 from the next cigarette stacking position 1.2 to the cigarette holding space 12. At this time, if... Figure 17 As shown.

[0068] 7. Next, the first lifting frame 6.1 of the pressing mechanism rises and resets.
