Description

Technical Field

[0001] The present invention relates to the technical field of cigarette boxes, and in particular to a system and method for splicing transparent paper on the outer surface of a cigarette box. Background Art

[0002] The ZB416 unit's design concept further caters to market demand. Besides improving packaging speed, it also offers unique advantages in product quality, efficiency, flexibility, reduced production costs, and ease of maintenance. As major tobacco factories continue to innovate in cigarette and package sizes, the number of product models and customized devices produced using the ZB416 unit is also steadily increasing.

[0003] Currently, the ZB416 machine utilizes a servo motor to automatically splice the transparent paper on the cigarette carton. The tape is held to the roller by negative pressure, and the servo motor rotates the roller, allowing the tape to adhere to both the new and old transparent paper on the cigarette carton. A cutter then cuts the old paper. While this solution automatically splices the new and old transparent paper, it requires an operator to apply the tape to the roller, which requires precise positioning of the tape, is difficult, and expensive, resulting in low production efficiency.

[0056] The embodiment of the present invention provides a system for splicing transparent paper on the outer surface of a cigarette box. Figure 1 1 is a schematic structural diagram of a transparent paper splicing system for a cigarette box provided by an embodiment of the present invention. Figure 2 This is a partial structural diagram of a transparent paper splicing system for a cigarette box provided by an embodiment of the present invention. Figure 3 This is a partial structural diagram of another system for splicing transparent paper on the outer surface of a cigarette box provided by an embodiment of the present invention. Figure 4 This is a partial structural diagram of another transparent paper splicing system for a cigarette box provided according to an embodiment of the present invention, with reference to Figure 1-Figure 4 , the transparent paper splicing system for cigarette box includes:

[0057] Control module 01, pressure sensor group, heater 3, heating wire module 5, valve island module 02, cylinder module 03, two negative pressure modules, upper pressure plate 7, connecting plate 22, first platform 12 and second platform 1;

[0058] The upper pressing plate 7 and the first platform 12 are arranged in sequence, and the upper pressing plate 7 is connected to the first platform 12 through the connecting plate 22. The heater 31 is arranged on the side of the upper pressing plate 7 close to the first platform 12. The two negative pressure modules are respectively arranged on the first platform 12 and the second platform 1. The heating wire module 5 is arranged on the second platform 1;

[0059] The first end of the control module 01 is electrically connected to the pressure sensor group, which is used to detect the vacuum pressure value of the negative pressure module on the platform corresponding to the new transparent paper roll in real time and transmit the vacuum pressure value to the control module 01;

[0060] The second end of the control module 01 is connected to the first end of the valve island module 02, the second end of the valve island module 02 is connected to the first end of the cylinder module 03, the second end of the cylinder module 03 is connected to the first platform 12 and the upper pressure plate 7, and the third end of the cylinder module 03 is connected to the heating wire module 5. The control module 01 is used to compare the vacuum pressure value with the preset vacuum pressure value when the old transparent paper roll and the new transparent paper roll need to be spliced. When the vacuum pressure value is less than the preset vacuum pressure value, a sealing and cutting signal is sent to the valve island module 02, and the first platform 12 and the upper pressure plate 7 are controlled to rotate to drive the heater 31 to perform heat sealing treatment on the old transparent paper and the new transparent paper, and the heating wire module 5 is controlled to cut the old transparent paper so that the old transparent paper and the new transparent paper are spliced.

[0061] The pressure sensor group includes a first pressure sensor 26 and a second pressure sensor 27. The two negative pressure modules are the first negative pressure module 9 and the second negative pressure module 4. For example, the second pressure sensor 27 is used to detect the vacuum pressure value of the first negative pressure module 9 on the first platform 12 in real time after a new transparent paper roll is replaced on the first platform 12. The first pressure sensor 26 is used to detect the vacuum pressure value of the second negative pressure module 4 on the second platform 1 in real time after a new transparent paper roll is replaced on the second platform 1. The valve island module 02 includes a valve island 17, a first valve disc 18, a second valve disc 19, a third valve disc 20, a fourth valve disc 21, a fifth valve disc 23, and a sixth valve disc 24. The cylinder module 03 includes a first cylinder 16, a second cylinder 31, and a third cylinder 32. The control module 01 may include a PLC unit, an input unit, and an output unit. The first end of the input unit is connected to the first pressure sensor 26 and the second pressure sensor 27. The second end of the input unit is connected to the first end of the PLC unit. The second end of the PLC unit is connected to the first end of the output unit. The second end of the output unit is connected to the first end of the valve island module 02. The sealing and cutting signals include a sealing signal and a cutting signal.

[0062] Specifically, when the old transparent paper roll on the platform is used up and the old transparent paper roll needs to be spliced ​​with a new transparent paper roll, the control module 01 compares the received vacuum pressure value with the preset vacuum pressure value. For example, the control module 01 can determine whether the old transparent paper roll is used up and whether the old transparent paper roll needs to be spliced ​​with the new transparent paper roll based on the received paper roll diameter information; it can also determine whether the old transparent paper roll needs to be spliced ​​with the new transparent paper roll based on the splicing signal generated by the manual splicing button triggered by the staff. The embodiment of the present invention is not limited to this. At this time, if the vacuum pressure value is greater than or equal to the preset vacuum pressure value, it means that the new transparent roll of paper has not been preset on the platform. At this time, the control module 01 will perform an alarm process to warn the staff to preset the new transparent roll of paper on the platform in time. For example, a red "roll not preset" message can be displayed on the display module 04. If the vacuum pressure value is less than the preset vacuum pressure value, it means that the new transparent roll of paper has been preset on the platform, and a sealing signal is sent to the valve island module 02. The valve island module 02 controls the cylinder module 03 to drive the first platform 12 and the upper pressure plate 7 to rotate, so that the heater 3 performs heat sealing treatment on the old transparent paper and the new transparent paper, and after the heater 31 performs heat sealing treatment on the old transparent paper and the new transparent paper, a cutting signal is sent to the valve island module 02. The valve island module 02 controls the cylinder module 03 to drive the heating wire module 5 to rotate to cut the old transparent paper, so that the old transparent paper and the new transparent paper are completed. Before splicing the old transparent paper roll and the new transparent paper roll, the staff needs to pre-place the new transparent paper roll on the platform in advance. At this time, if the vacuum pressure value is greater than or equal to the preset vacuum pressure value, it means that the new transparent paper roll has not been pre-placed on the platform. For example, a blue "new roll not pre-placed" message can be displayed on the display module 04 to remind the staff to pre-place the new transparent paper roll on the platform.

[0063] Exemplarily, the control module 01 determines whether the transparent paper roll on the first platform 12 is the old transparent paper roll or the transparent paper roll on the second platform 1 is the old transparent paper roll by receiving the rotation information of the transparent paper roll in real time. Exemplarily, if the rotation information comes from the transparent paper roll on the first platform 12, it means that the transparent paper roll on the first platform 12 is the old transparent paper roll and the transparent paper roll on the second platform 1 is the new transparent paper roll; if the rotation information comes from the transparent paper roll on the second platform 1, it means that the transparent paper roll on the second platform 1 is the old transparent paper roll and the transparent paper roll on the first platform 12 is the new transparent paper roll.

[0064] like Figure 2As shown, if the transparent paper roll on the second platform 1 is old and the transparent paper roll on the first platform 12 is new, before splicing the old and new transparent paper rolls, a staff member must pre-position the new transparent paper roll on the first platform 12. The first new transparent paper roll 10 on the first platform 12 is pulled to the first platform 12, and the control module 01 sends a first suction signal to the valve island 17, so that the sixth valve plate 24 on the valve island 17 receives the first suction signal. At this time, the first negative pressure module 9 continuously applies negative pressure to the first new transparent paper roll 10, so that the first new transparent paper roll 10 is pre-positioned on the first platform 12. When the old transparent paper roll on the second platform 1 is used up and the old and new transparent paper rolls need to be spliced, the vacuum pressure value of the first negative pressure module 9 detected by the second pressure sensor 27 can be compared with the preset vacuum pressure value. If the vacuum pressure value of the first negative pressure module 9 is less than the preset vacuum pressure value, it indicates that the first new transparent paper roll 10 has been pre-positioned on the first platform 12.

[0065] like Figure 3 As shown, if the transparent paper roll on the first platform 12 is old and the transparent paper roll on the second platform 1 is new, before splicing the old and new transparent paper rolls, a staff member must pre-position the new transparent paper roll on the second platform 1. The second new transparent paper roll 14 on the second platform 1 is pulled to the second platform 1, and the control module 01 sends a second suction signal to the valve island 17, so that the fifth valve plate 23 on the valve island 17 receives the second suction signal. At this time, the second negative pressure module 4 continuously applies negative pressure to the second new transparent paper roll 14, so that the second new transparent paper roll 14 is pre-positioned on the second platform 1. When the old transparent paper roll on the first platform 12 is used up and the old and new transparent paper rolls need to be spliced, the vacuum pressure value of the second negative pressure module 4 detected by the first pressure sensor 26 can be compared with the preset vacuum pressure value. If the vacuum pressure value of the second negative pressure module 4 is less than the preset vacuum pressure value, it indicates that the second new transparent paper roll 14 has been pre-positioned on the second platform 1.

[0066] The embodiment of the present invention provides a system for splicing the outer transparent paper of a cigarette box, which detects the vacuum pressure value of the negative pressure module on the platform corresponding to the new transparent paper roll in real time through a pressure sensor group, and transmits the vacuum pressure value to the control module 01. When the old transparent paper roll and the new transparent paper roll need to be spliced ​​together, the control module 01 compares the vacuum pressure value with the preset vacuum pressure value. When the vacuum pressure value is less than the preset vacuum pressure value, the control module 01 sends a sealing and cutting signal to the valve island module 02, controls the first platform 12 and the upper pressure plate 7 to rotate and drive the heater 31 to heat-seal the old transparent paper and the new transparent paper, and controls the heating wire module 5 to cut the old transparent paper so that the old transparent paper and the new transparent paper are spliced ​​together. Compared with the prior art in which a servo motor is used to drive the roller to rotate so that the tape sticks the old transparent paper roll and the new transparent paper roll together, and then the old transparent paper roll is cut by a cutter, the operation difficulty is small, and the splicing efficiency of the outer transparent paper of the cigarette box is improved. In addition, the present invention does not require the installation of a servo motor and has lower cost.

[0067] Further, Figure 5 This is a schematic diagram of the structure connection of another transparent paper splicing system for cigarette box provided by an embodiment of the present invention, with reference to Figure 2-Figure 5 , the transparent paper splicing system for cigarette box also includes:

[0068] Relay module 05;

[0069] The first end of the relay module 05 is connected to the third end of the control module 01, and the second end of the relay module 05 is connected to the heater 3 and the heating wire module 5;

[0070] Control module 01 is used to:

[0071] After the transparent paper splicing system on the outside of the cigarette box is started, the heater 3 is heated;

[0072] When the vacuum pressure value is less than the preset vacuum pressure value, a heating signal is sent to the relay module 05 to control the heating wire module 5 to be powered on for heating for a first preset time period;

[0073] Send a sealing signal to the valve island module 02, which controls the cylinder module 03 to rotate the first platform 12 and the upper pressing plate 7, so that the heater 3 performs heat sealing on the old transparent paper and the new transparent paper;

[0074] A cutting signal is sent to the valve island module 02, which controls the cylinder module 03 to drive the heating wire module 3 to rotate, so as to cut the old transparent paper and complete the splicing of the old transparent paper and the new transparent paper.

[0075] Among them, the relay module includes a first relay and a second relay. The first relay and the second relay can be solid-state relays of the same model or solid-state relays of different models. For example, the first relay is connected to the heater, and the first relay can be loaded with 110V AC power; the second relay is connected to the heating wire module, and the second relay can be loaded with 24V AC power.

[0076] Specifically, after the control module 01 starts the system for splicing the transparent paper outside the cigarette box, the control module 01 controls the heater 3 to heat the cigarette box via the relay module 05. Furthermore, when the vacuum pressure value is less than a preset vacuum pressure value, the relay module 05 controls the heating wire module 5 to energize and heat the cigarette box for a first preset time period to complete the preparation work before splicing the old transparent paper with the new transparent paper. For example, the first preset time period can be set according to actual conditions and is not limited in this embodiment of the present invention. After completing the preparations for splicing the old transparent paper and the new transparent paper, the cylinder module 03 is controlled by the valve island module 02 to drive the first platform 12 and the upper pressure plate 7 to rotate, so that the heater 3 performs heat-sealing treatment on the old transparent paper and the new transparent paper. For example, a first proximity switch 25 can be set in the splicing system, and the first proximity switch 25 is connected to the control module 01. The state of the first proximity switch 25 is used to judge whether the heater 3 of the upper pressure plate 7 has reached the specified position. If the state of the first proximity switch 25 is on, it means that the heater 3 of the upper pressure plate 7 has reached the specified position. If the state of the first proximity switch 25 is off, it means that the heater 3 of the upper pressure plate 7 has not reached the specified position. At this time, the splicing system can be controlled to perform a stop alarm process to interrupt the splicing, and a red "box transparent paper splicing heater has not moved" message is displayed on the display module 04 to remind the staff to perform maintenance. After the heater 3 heat-seals the old transparent paper and the new transparent paper, the valve island module 02 controls the cylinder module 03 to drive the heating wire module 5 to rotate to cut the old transparent paper and complete the splicing of the old transparent paper and the new transparent paper. For example, a second proximity switch 28, a third proximity switch 29 and a fourth proximity switch 30 can be set in the splicing system, and the second proximity switch 28, the third proximity switch 29 and the fourth proximity switch 30 are connected to the control module 01. The status of the second proximity switch 28, the third proximity switch 29 and the fourth proximity switch 30 is used to determine whether the heating wire module 5 has reached the specified position. If the heating wire module 5 has not reached the specified position, the splicing system can be controlled to perform a stop alarm to interrupt the splicing, and a red message "The strip box transparent paper splicing heating wire module has not moved" can be displayed on the display module 04 to remind the staff to perform maintenance.

[0077] For example, Figure 2As shown, if the transparent paper roll on the second platform 1 is an old transparent paper roll and the transparent paper roll on the first platform 12 is a new transparent paper roll, after completing the preparations for splicing the old and new transparent paper rolls, the control module 01 sends a first control signal to the valve island 17 to energize the first valve disc 18 on the valve island 17, thereby extending the first cylinder 16, thereby driving the heater 3 to heat-seal and press the first new transparent paper roll 10 and the second old transparent paper roll 13 through the first platform 12 and the upper pressure plate 7. After the first new transparent paper roll 10 and the second old transparent paper roll 13 are heat-sealed and pressed, the control module 01 sends a second control signal to the valve island 17 to energize the second valve disc 19 and the third valve disc 20 on the valve island 17, thereby extending the second cylinder 31 and the third cylinder 32, thereby driving the heating wire module 5 to rotate upward via the rotating rod 8 connected to the heating wire module 5. If the state of the second proximity switch 28 is closed, the state of the third proximity switch 29 is open, and the state of the fourth proximity switch 30 is open, it means that the heating wire module 5 has reached the specified position. If the second proximity switch 28, the third proximity switch 29 and the fourth proximity switch 30 do not meet the above conditions, it means that the heating wire module 5 has not reached the specified position.

[0078] like Figure 3 As shown, if the transparent paper roll on the first platform 12 is an old transparent paper roll and the transparent paper roll on the second platform 1 is a new transparent paper roll, after completing the preparations for splicing the old and new transparent paper rolls, the control module 01 sends a first control signal to the valve island 17 to energize the first valve disc 18 on the valve island 17, thereby extending the first cylinder 16, thereby driving the heater 3 to heat-seal and press the second new transparent paper roll 14 and the first old transparent paper roll 15 through the first platform 12 and the upper pressure plate 7. After the second new transparent paper roll 14 and the first old transparent paper roll 15 are heat-sealed and pressed, the control module 01 sends a second control signal to the valve island 17 to de-energize the second valve disc 19 and the third valve disc 20 on the valve island 17, thereby preventing the second cylinder 31 and the third cylinder 32 from extending, thereby driving the heating wire module 5 to rotate downward via the rotating rod 8 connected to the heating wire module 5. If the second proximity switch 28 is in the on state, the third proximity switch 29 is in the on state, and the fourth proximity switch 30 is in the off state, it means that the heating wire module 5 has reached the specified position. If the second proximity switch 28, the third proximity switch 29 and the fourth proximity switch 30 do not meet the above conditions, it means that the heating wire module 5 has not reached the specified position.

[0079] For further reference, Figure 2 and Figure 3 , the transparent paper splicing system for cigarette box also includes:

[0080] The first blowing module 11 is provided on one side of the second platform 1 close to the connecting plate 22, and the first blowing module 11 is connected to the fourth end of the control module through the valve island module;

[0081] The control module is used to:

[0082] When the old transparent paper is cut by the heating wire module 5 , a first blowing signal is sent to the first blowing module 11 to control the first blowing module 11 to perform the blowing process.

[0083] Specifically, when the old transparent paper is cut by the heating wire module 5, the first blowing signal is sent to the valve island 17 through the control module to energize the fourth valve plate 21 on the valve island 17, and then the first blowing module 11 receives the first blowing signal and performs blowing processing, so that the cut old transparent paper is kept away from the heating wire module 5 to prevent the temperature emitted by the heating wire module 5 from causing the cut old transparent paper to curl.

[0084] For further reference, Figure 1-Figure 3 , control module 01 is used to:

[0085] After the old transparent paper is cut by the heating wire module 5, a return signal of the heating wire module 5 is sent to the valve island module 02, so that the valve island module 02 controls the cylinder module 03 to drive the heating wire module 5 to rotate to the position before the cutting process.

[0086] Specifically, after the old transparent paper is cut by the heating wire module 5, the control module 01 sends a heating wire module reset signal to the valve island 17, so that the second valve plate 19 on the valve island 17 is energized and the third valve plate 20 is not energized, thereby causing the second cylinder 31 to extend and the third cylinder 32 to not extend, thereby achieving the goal of driving the heating wire module 5 back to its initial horizontal position, i.e., the position before the cutting process, by the rotating rod 8 connected to the heating wire module 5. At this time, if the state of the second proximity switch 28 is closed, the state of the third proximity switch 29 is closed, and the state of the fourth proximity switch 30 is closed, it means that the heating wire module 5 has reached the initial horizontal position. If the three proximity switch states do not meet the above conditions, it means that the heating wire module 5 has reached the initial horizontal position. At this time, the splicing system can be controlled to perform a stop alarm process to interrupt the splicing. For example, a red message "The strip box transparent paper splicing heating wire module has not moved" can be displayed on the display module 04. At this time, the control module 01 can send a blowing stop signal to the valve island 17 to de-energize the fourth valve plate 21 on the valve island 17, so that the first blowing module 11 receives the blowing stop signal to control the first blowing module 11 to stop blowing.

[0087] For further reference, Figure 1-Figure 3 , the control module is also used to:

[0088] After the heating wire module 5 rotates to the position before cutting, the heater 3 is controlled to perform heat sealing on the old transparent paper and the new transparent paper for the second preset time, and a heater return signal is sent to the valve island module 02, so as to control the cylinder module 03 through the valve island module 02 to drive the first platform 12 and the upper pressure plate 7 to rotate to the position before heat sealing.

[0089] The second preset duration can be set according to actual conditions, and the embodiment of the present invention does not limit this.

[0090] Specifically, after the heating wire module 5 rotates to the position before cutting, the heater 3 is controlled to heat-seal the old and new transparent paper for a second preset time, ensuring that the old and new transparent paper are spliced ​​together and avoiding separation. After the heater 3 is controlled to heat-seal the old and new transparent paper for a second preset time, the control module 01 sends a heater reset signal to the valve island 17, so that the first valve plate 18 on the valve island 17 is de-energized, thereby preventing the first cylinder 16 from extending, thereby enabling the first platform 12 and the upper platen 7 to drive the heater 3 to rotate to the initial position, that is, to the position before heat sealing. At this time, if the state of the first proximity switch 25 is closed, it can be determined that the heater 3 of the upper platen 7 has reached the specified position. If it has not reached the specified position, the splicing system is controlled to perform a stop alarm process to interrupt the splicing, and a red message "Strip box transparent paper splicing heater has not moved" is displayed on the display module to remind the staff to perform maintenance.

[0091] After the splicing of the old and new transparent papers is completed, the overlapping mark at the connection between the old and new transparent papers is removed. After the mark is removed, the machine runs at a low speed for a third preset time to end the splicing.

[0092] Further, Figure 6 This is a structural connection diagram of another transparent paper splicing system for a cigarette box provided according to an embodiment of the present invention, with reference to Figure 6 , the transparent paper splicing system for cigarette box also includes:

[0093] Protective door status monitoring module 06, cooling and blowing module 6;

[0094] The protective door status monitoring module 06 is connected to the fifth terminal of the control module 01. The protective door status monitoring module 06 is used to monitor the working status of the protective door in real time, generate protective door status information, and transmit the protective door status information to the control module 01;

[0095] The control module 01 is connected to the cooling and blowing module 6. The control module 01 is used to control the transparent paper splicing system outside the cigarette box to stop working when the protective door status information is the protective door open state, and control the cooling and blowing module 6 to perform cooling and blowing treatment on the transparent paper splicing system outside the cigarette box.

[0096] Specifically, the protective door status monitoring module 06 needs to monitor the working status of the protective door in real time, and when it detects that the protective door is open, it controls the transparent paper splicing system outside the cigarette box to stop working through the control module 01 to avoid fire caused by excessive temperature inside the transparent paper splicing system outside the cigarette box. At this time, the cooling and blowing module 6 can be controlled to perform cooling and blowing treatment on the transparent paper splicing system outside the cigarette box to reduce the temperature inside the splicing system, and at the same time, an alarm can be issued to the staff. For example, a red "splicing safety protective door is open" message can be displayed on the display module.

[0097] Further, Figure 7 This is a structural connection diagram of another transparent paper splicing system for a cigarette box provided according to an embodiment of the present invention, with reference to Figure 2 and Figure 7 , the transparent paper splicing system for cigarette box also includes:

[0098] Thermocouple module 2;

[0099] The thermocouple module 2 is connected to the sixth end of the control module 01; the thermocouple module 2 is used to detect the heating temperature of the heater 3 in real time and transmit the heating temperature to the control module 01;

[0100] The control module 01 is used to control the transparent paper splicing system outside the cigarette box to stop working when the heating temperature is not within the first preset temperature range.

[0101] Among them, the first preset temperature range can be set according to the first preset temperature, and the first preset temperature can be set according to actual conditions. For example, the first preset temperature range can be within 10°C above and below the first preset temperature. If the first preset temperature is 130°C, the first preset temperature range is between 120°C and 140°C.

[0102] Specifically, if the heating temperature of the heater 3 is not within the first preset temperature range at this time, it means that the heating temperature of the heater 3 is too low or too high, and the effect of heat sealing the old transparent paper and the new transparent paper is not good at this time. For example, if the heating temperature of the heater 3 is lower than the first preset temperature range, it means that the heating temperature of the heater 3 is too low, and the old transparent paper and the new transparent paper cannot be spliced ​​together. At this time, it is necessary to control the transparent paper splicing system outside the cigarette box to stop working, improve the heating temperature of the heater 3, and perform alarm processing. For example, a red message "Transparent paper splicing heater is not ready" can be displayed on the display module.

[0103] For further reference, Figure 1 , the transparent paper splicing system for cigarette box also includes:

[0104] Display module 04; Display module 04 is connected to control module 01;

[0105] Control module 01 is used to:

[0106] When an abnormality occurs in the operation of the transparent paper splicing system on the outer side of the cigarette box, the control display module 04 displays a splicing abnormality message.

[0107] Specifically, serious fault information in the transparent paper splicing system outside the cigarette box can be indicated by red information. For example, serious fault information includes "splicing safety protection door is open" information, "transparent paper splicing heater for cigarette box is not ready" information, "reel not preset" information, etc. If the display module 04 displays red information, the staff can trigger the zero switch to reset the splicing system to zero, so that the splicing system returns to the initial position before splicing, which is convenient for the staff to deal with the problem; blue information can also be used to indicate prompt fault information in the transparent paper splicing system outside the cigarette box. For example, prompt fault information includes "new reel not preset" etc.

[0108] Further, such as Figure 2 As shown, the control module is used to:

[0109] When the vacuum pressure value of the negative pressure module on the second platform 1 is less than the preset vacuum pressure value, second blowing information is sent to the first blowing module 11 to control the first blowing module 11 to perform blowing processing.

[0110] Specifically, if the vacuum pressure value of the second negative pressure module 4 on the second platform 1 is less than the preset vacuum pressure value, it means that the second new transparent paper roll has been pre-placed on the second platform 1. Since a part of the second new transparent paper roll needs to be extended outside the second platform 1, the first blowing module 11 is controlled to blow air to the second new transparent paper roll extending outside the second platform 1 to avoid wrinkles and deformation of the second new transparent paper roll due to the close distance between the second new transparent paper roll and the heating wire module 5.

[0111] The embodiment of the present invention provides a method for splicing the transparent paper outside a cigarette box. Figure 8 This is a flow chart of a method for splicing transparent paper on the outer surface of a cigarette box according to an embodiment of the present invention. Figure 8 , the methods for splicing the transparent paper outside the cigarette box include:

[0112] S110 , the pressure sensor group detects the vacuum pressure value of the negative pressure module on the platform corresponding to the new transparent paper roll in real time, and transmits the vacuum pressure value to the control module.

[0113] S120. When the old transparent paper roll and the new transparent paper roll need to be spliced ​​together, the control module compares the vacuum pressure value with the preset vacuum pressure value. When the vacuum pressure value is less than the preset vacuum pressure value, the control module sends a sealing and cutting signal to the valve island module, controls the first platform and the upper pressure plate to rotate to drive the heater to heat-seal the old transparent paper and the new transparent paper, and controls the heating wire module to cut the old transparent paper so that the old transparent paper and the new transparent paper are spliced ​​together.

[0114] The embodiment of the present invention provides a method for splicing transparent paper outside a cigarette box, which corresponds to the system for splicing transparent paper outside a cigarette box. A pressure sensor is used to detect in real time the vacuum pressure value of the negative pressure module on the platform corresponding to the new transparent paper roll, and the vacuum pressure value is transmitted to the control module. When the old transparent paper roll and the new transparent paper roll need to be spliced ​​together, the control module compares the vacuum pressure value with a preset vacuum pressure value. When the vacuum pressure value is less than the preset vacuum pressure value, a sealing and cutting signal is sent to the valve island module to control the first platform and the upper pressure plate to rotate and drive the heater to heat-seal the old transparent paper and the new transparent paper, and control the heating wire module to cut the old transparent paper so that the old transparent paper and the new transparent paper are spliced ​​together. Compared with the prior art in which a servo motor is used to drive the roller to rotate so that the tape sticks the old transparent paper roll and the new transparent paper roll together, and then the old transparent paper roll is cut by a cutter, the operation difficulty is small, the splicing efficiency of the transparent paper outside the cigarette box is improved, and the present invention does not require the arrangement of a servo motor, and the cost is lower.

[0115] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in the present invention can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solution of the present invention can be achieved. This is not limited herein.

[0116] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
