Description

Technical Field

[0001] The present application relates to the field of cigarette packaging, and in particular to a cigarette pack anti-scorching device and method for the seventh wheel of a cigarette packaging machine. Background Art

[0002] A cigarette packaging machine refers to a packaging device that packages a certain number of cigarettes into cigarette packs, and then packages the cigarette packs into strip boxes. The current mainstream GDX2 packaging machine uses eight rotating packaging wheels to realize the action of packaging cigarettes into cigarette packs. Among them, the seventh wheel is composed of thirty-six intermittently rotating mold boxes and upper and lower soldering irons, which are responsible for drying the adhesive glue on the two sides of the cigarette pack to ensure the packaging quality of the cigarette pack. Its working process is that after the process of the sixth wheel is completed, the cigarette pack is pushed into the mold box by the push rod in the static phase of the seventh wheel, and then rotated forward with the seventh wheel in turn, and entered the eighth wheel after passing through twenty-seven stations. The upper and lower sides of the seventh wheel are provided with soldering irons that move up and down. In the static phase, the upper and lower soldering irons are close to the two sides of the cigarette pack, and the white latex used for pasting on the side of the cigarette pack is quickly solidified through heating and extrusion.

[0003] In the production process of existing packaging machines, when the equipment temporarily stops running, the upper and lower soldering irons need to be kept on for heating to ensure that the soldering irons are kept at a constant heating temperature so that the equipment can work normally immediately when it resumes running. However, when the temporary shutdown time of the packaging machine exceeds the set value, the cigarette packs trapped in the seventh wheel will still be damaged by the long-term baking of the soldering iron, and the damaged cigarette packs will be removed in the eighth wheel according to the production process requirements. However, due to equipment failures, raw material replacements and other reasons during the production process of the packaging machine, multiple temporary shutdowns are inevitable, and each shutdown will produce a large number of burnt and damaged cigarette packs, resulting in a large amount of material waste.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0034] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0035] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings represent the same or similar parts, and thus their repeated description will be omitted.

[0036] In this exemplary embodiment, a cigarette pack anti-scorching device for the seventh wheel of a cigarette packaging machine is first provided. Figure 1 to Figure 2 As shown in the figure, the cigarette pack anti-scorching device for the seventh wheel of the cigarette packaging machine includes:

[0037] The jet heat insulation component 100 is fixed on the seventh wheel component 400 of the cigarette packaging machine, and the output end is used to jet heat insulation to the first gap between the bottom surface of the upper soldering iron 410 of the seventh wheel component 400 and the top surface of the cigarette pack 430 and the second gap between the top surface of the lower soldering iron 420 of the seventh wheel component 400 and the bottom surface of the cigarette pack 430;

[0038] The air source component 200 has an output end connected to the input end of the air jet heat insulation component 100 and is used to supply air to the air jet heat insulation component 100 .

[0039] Through the above technical scheme, air can be supplied to the jet insulation component 100 through the air source component 200, and air can be sprayed into the first gap and the second gap between the upper soldering iron 410 and the lower soldering iron 420 of the seventh wheel component 400 and the cigarette pack 430, so as to isolate the heat of the upper soldering iron 410 and the lower soldering iron 420 from the cigarette pack 430, thereby preventing the cigarette pack 430 from being scorched by high temperature.

[0040] In a possible implementation, the jet heat insulation assembly 100 includes a jet component 110 and a fixing component 120 , one end of the fixing component 120 is fixed to the bracket 440 of the seventh wheel assembly 400 , and the other end is fixedly connected to the jet component 110 .

[0041] It should be noted that the jetting member 110 is fixedly connected to the bracket 440 of the seventh wheel assembly 400 via the fixing member 120, so that the installation can be performed with little impact on the equipment structure and the working process.

[0042] Optionally, the fixing member 120 is detachably connected to the bracket 440 and the jet member 110, so as to facilitate disassembly, repair, maintenance and cleaning of the jet heat insulation assembly 100.

[0043] Furthermore, the jet component 110 has an air inlet end 111, a first jet end 112 and a second jet end 113, and the air inlet end 111 is connected to the output end of the gas source component 200; the first jet end 112 is located between the bottom surface of the upper soldering iron 410 of the seventh wheel assembly 400 and the top surface of the cigarette pack 430, and is used to spray air into the first gap for heat insulation; the second jet end 113 is located between the top surface of the lower soldering iron 420 of the seventh wheel assembly 400 and the bottom surface of the cigarette pack 430, and is used to spray air into the second gap for heat insulation.

[0044] It is understandable that, optionally, the jet component 110 has two output ends, namely a first jet end 112 and a second jet end 113, and the first jet end 112 and the second jet end 113 are aligned with the first gap and the second gap respectively, and can spray into the first gap and the second gap when the air source component 200 supplies air.

[0045] In a possible implementation manner, there are a plurality of the air jet insulation components 100 , and the air jet ranges of every two adjacent air jet components 110 have an overlapping area.

[0046] It should be noted that the plurality of jet insulation assemblies 100 are evenly distributed along the circumference of the seventh wheel, and the airflow injection areas of the jet insulation assemblies 100 overlap with each other, covering the entire upper soldering iron 410 and the lower soldering iron 420 area, thereby achieving comprehensive insulation.

[0047] In a possible implementation manner, the gas source assembly 200 includes a gas source 210 and a switch valve 220 ; the gas source 210 is connected to the gas jet insulation assembly 100 through the switch valve 220 .

[0048] It is understandable that the air source 210 is controlled by the switch valve 220 to supply air to the air jet insulation assembly 100, thereby controlling the air jet start and stop of the air jet insulation assembly 100.

[0049] Furthermore, the gas source assembly 200 further includes a refrigeration element 230 , an input end of the refrigeration element 230 is in communication with the gas source 210 , and a refrigeration element cold end 232 of the refrigeration element 230 is in communication with the air jet insulation assembly 100 .

[0050] It should be noted that the refrigeration component 230 has a refrigeration component hot end 231 and a refrigeration component cold end 232. The refrigeration component hot end 231 is emptied for heat dissipation, and the refrigeration component cold end 232 is connected to the jet insulation component 100 to transport low-temperature airflow to the jet insulation component 100 to enhance the insulation effect.

[0051] Optionally, the refrigeration element 230 is a vortex tube refrigerator.

[0052] In a possible implementation manner, the gas source assembly 200 further includes a pressure reducing valve 240 , and the pressure reducing valve 240 is connected between the gas source 210 and the switch valve 220 to adjust the gas supply pressure.

[0053] It is understandable that the air supply pressure is regulated by the pressure reducing valve 240 to prevent the air supply pressure from being too high, thereby avoiding the influence of the heat insulation effect and the damage of the equipment caused by the excessive air supply pressure.

[0054] In a possible implementation, the gas source assembly 200 further includes a throttle valve 250 , and the throttle valve 250 is connected between the gas source 210 and the switch valve 220 to adjust the gas supply flow rate.

[0055] It is understandable that the air supply flow rate is adjusted by the throttle valve 250 to prevent the air supply flow rate from being too large / too small and affecting the thermal insulation effect.

[0056] In a possible implementation manner, the air jet insulation assembly 100 is connected to the air source assembly 200 via an air pipe 300 .

[0057] It is understandable that when there are multiple air jet heat insulation assemblies 100 , the air source assembly 200 has multiple output ends and can be connected to the multiple air jet heat insulation assemblies 100 through multiple air pipes 300 .

[0058] Further, such as Figure 3As shown, in this exemplary embodiment, a method for preventing cigarette packs from being scorched on the seventh wheel of a cigarette packaging machine is also provided, comprising:

[0059] Step S100 is that when the cigarette packaging machine is temporarily stopped, the upper soldering iron and the lower soldering iron of the seventh wheel assembly are located in a closed position to continue drying the cigarette packs.

[0060] Step S200 is that when the cigarette packaging machine is temporarily stopped for more than a preset time, the upper soldering iron and the lower soldering iron are opened and respectively away from the side of the cigarette pack to form a first gap and a second gap, and jet insulation is performed to the first gap and the second gap through a jet insulation component.

[0061] Step S300 is that when the cigarette packaging machine resumes operation, the air source component stops supplying air to the jet insulation component, the upper soldering iron and the lower soldering iron are closed and work normally, and the cigarette packs retained in the No. 7 wheel component enter the No. 8 wheel of the cigarette packaging machine in sequence.

[0062] It is understandable that the preset time is determined between 10s and 90s according to the type and specification of the cigarette pack, ensuring that the cigarette pack will not be burnt within the preset time, and shortening the jet time of the jet insulation component as much as possible to reduce gas source consumption.

[0063] It should be noted that when the cigarette packaging machine is working normally, the cigarette pack is pushed into the mold box by the push rod in the static phase of the No. 7 wheel assembly, and then rotated forward in sequence with the No. 7 wheel assembly and entered the No. 8 wheel after passing through twenty-seven stations. The upper and lower surfaces of the No. 7 wheel assembly are provided with upper and lower soldering irons that move up and down. In the static phase, the upper and lower soldering irons are pressed against the two sides of the cigarette pack, and the white latex used for pasting on the sides of the cigarette pack is quickly solidified through heating and extrusion. When the packaging machine is temporarily stopped, the upper and lower soldering irons remain in the closed position, and the cigarette packs are continuously dried to ensure that the cigarette packs retained in the No. 7 wheel assembly are firmly bonded. After the cigarette packaging machine is temporarily stopped for more than the preset time, the upper and lower soldering irons are opened by the mechanism, and are about 5mm away from the sides of the cigarette pack. The switch valve is opened, and the compressed air is converted into cooling airflow through the vortex tube cooler and ejected from the first and second jet ends of the jet element. The airflow continues to flow through the first gap and the second gap, isolating the high-temperature baking effect of the upper and lower soldering irons, providing a protective environment for the cigarette packs and preventing them from being scorched. After the packaging machine resumes operation, the switch valve is closed, the jet is stopped, and the upper and lower soldering irons are closed to work normally. The undamaged cigarette packs retained in the seventh wheel assembly enter the eighth wheel in turn and are no longer rejected.
