[0051] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0052] like Figure 1 As shown, according to a first aspect of the embodiments of this application, a glue supply system is proposed, including: a glue tank assembly 11, a first glue dispensing tube assembly 12, a second glue dispensing tube assembly 13, and an air supply system 14; the glue tank assembly 11 contains glue; a first end of the first glue dispensing tube assembly 12 is connected to the glue tank assembly 11, and a second end of the first glue dispensing tube assembly 12 extends to a first glue application point; a first end of the second glue dispensing tube assembly 13 is connected to the glue tank assembly 11, and a second end of the second glue dispensing tube assembly 13 extends to a second glue application point; the air supply system 14 includes a first air blowing tube 141 and a second air blowing tube assembly 142, the output end of the first air blowing tube 141 is connected to the glue tank assembly 11 to force glue into the first glue dispensing tube assembly 12 through the first air blowing tube 141; the first output end of the second air blowing tube assembly 142 is connected to the glue tank assembly 11 to force glue into the second glue dispensing tube assembly 13 through the second air blowing tube assembly 142.

[0053] The glue supply system provided in this embodiment includes a glue tank assembly 11, a first glue dispensing pipe assembly 12, a second glue dispensing pipe assembly 13, and an air supply system 14. The air supply system 14 pressurizes the glue into the first glue dispensing pipe assembly 12 and the second glue dispensing pipe assembly 13. The first glue dispensing pipe assembly 12 supplies glue to the first glue application point, and the second glue dispensing pipe assembly 13 supplies glue to the second glue application point. The dual-channel structure allows for glue supply to different workstations, ensuring that the glue supply amounts at the first and second glue application points do not interfere with each other. This facilitates separate control of the glue supply amounts at the first and second glue application points, thereby reducing glue overflow and glue detachment in cigarette packs and improving the packaging qualification rate of cigarette packs.

[0054] Furthermore, the adhesive container assembly 11 contains different types of adhesive. The first adhesive is delivered to the first adhesive application point through the first adhesive dispensing pipe assembly 12, and the second adhesive is delivered to the second adhesive application point through the second adhesive dispensing pipe assembly 13. This satisfies the different viscosity requirements of the side ear position and the side seal position of the cigarette pack, thereby reducing the occurrence of adhesive overflow and opening of the cigarette pack. At the same time, it ensures the adhesion of the side ear position and the side seal position of the cigarette pack, and improves the packaging qualification rate of the cigarette pack.

[0055] Furthermore, the glue supply system was modified based on the original YP418 hard box packaging machine. It adopts a dual-channel form to supply glue to the first glue application point and the second glue application point separately, which realizes effective control of the glue supply at the side ears and side seals of the finished cigarette boxes, and solves the problem of glue opening or overflow at the side ears and side seals of the finished cigarette boxes.

[0056] Specifically, the first glue application point is the side ear of the cigarette pack, and the second glue application point is the side seal of the cigarette pack.

[0057] like Figure 1 As shown, in one feasible embodiment, the adhesive container assembly 11 includes a first adhesive container 111 and a second adhesive container 112. The first adhesive container 111 contains adhesive, and the second adhesive container 112 contains adhesive. The first end of the first dispensing tube assembly 12 is connected to the first adhesive container 111, and the output end of the first air blowing tube 141 is connected to the first adhesive container 111, so that the adhesive in the first adhesive container 111 is pressed into the first dispensing tube assembly 12 through the first air blowing tube 141. The first end of the second dispensing tube assembly 13 is connected to the second adhesive container 112, and the first output end of the second air blowing tube assembly 142 is connected to the second adhesive container 112, so that the adhesive in the second adhesive container 112 is pressed into the second dispensing tube assembly 13 through the second air blowing tube assembly 142.

[0058] In this technical solution, two glue storage areas are divided within the glue tank assembly. The glue in the first glue tank 111 is pumped into the first glue outlet assembly 12 via the first air blowing pipe 141, enabling independent glue supply from the first glue tank 111 to the first glue outlet assembly 12, thus facilitating control of the glue supply amount at the first glue application point. Similarly, the glue in the second glue tank 112 is pumped into the second glue outlet assembly 13 via the second air blowing pipe assembly 142, enabling independent glue supply from the second glue tank 112 to the second glue outlet assembly 13, thus facilitating control of the glue supply amount at the second glue application point. The separate glue supply from the first glue tank 111 and the second glue tank 112 ensures that the glue outlet channels at the first and second glue application points are completely independent, improving the accuracy of glue supply control at both points.

[0059] Furthermore, the first glue tank 111 contains the first glue liquid, which is delivered to the first glue application point through the first glue dispensing pipe assembly 12; the second glue tank 112 contains the second glue liquid, which is delivered to the second glue application point through the second glue dispensing pipe assembly 13, in order to meet the different viscosity requirements of the side ear position and the side seal position of the cigarette pack, thereby reducing the occurrence of glue opening of the cigarette pack, improving the packaging qualification rate of the cigarette pack, and at the same time preventing the overflowing glue liquid from sticking to the equipment and causing equipment failure, so as to improve the safety of production.

[0060] In some examples, the first glue bucket 111 and the second glue bucket 112 can also contain the same type of glue. By controlling the amount of glue supplied, the problems of glue opening and glue overflow in the cigarette packs can be reduced, thereby improving the pass rate of the cigarette packs.

[0061] In some examples, the first glue bucket 111 and the second glue bucket 112 can be placed separately, or the first glue bucket 111 and the second glue bucket 112 can be placed together. The positions of the first glue bucket 111 and the second glue bucket 112 are adjusted according to the actual available space of the glue supply system.

[0062] like Figure 1 As shown, in one feasible embodiment, the glue supply system further includes: a first glue pump 15, the drive end of the first glue pump 15 being connected to the first air blowing pipe 141, the first end of the first glue pump 15 being connected to the first glue tank 111, and the second end of the first glue pump 15 being connected to the first glue outlet assembly 12, so as to send the glue in the first glue tank 111 into the first glue outlet assembly 12 through the first glue pump 15.

[0063] In this technical solution, a first glue pump 15 is provided on the first glue dispensing tube assembly 12. The first glue pump 15 is driven by compressed air blown out by the first air blowing tube 141. The glue in the first glue tank 111 is sucked into the first glue dispensing tube assembly 12 by the first glue pump 15, and the amount of glue entering the first glue dispensing tube assembly 12 is controlled by the first glue pump 15.

[0064] Furthermore, the first adhesive pump 15 is a diaphragm pump. The first adhesive pump 15 has a built-in first suction tube. The first adhesive pump 15 is driven by the compressed air discharged from the first air blowing pipe 141, and then draws out the adhesive in the first adhesive tank 111 through the first suction tube inside the first adhesive pump 15 and delivers it to the first adhesive outlet tube assembly 12.

[0065] like Figure 1 As shown, in one feasible embodiment, the first dispensing tube assembly 12 includes: a first pipe 121 and a glue sprayer 122; the first end of the first pipe 121 is connected to the first glue tank 111, and the second end of the first pipe 121 extends to the first glue application point; the glue sprayer 122 is disposed at the second end of the first pipe 121, and the glue sprayer 122 sprays glue onto the first glue application point.

[0066] In this technical solution, the first adhesive pump 15 is installed on the first pipeline 121. The first adhesive pump 15 transports the adhesive in the first adhesive tank 111 to the adhesive sprayer 122 through the first pipeline 121, and sprays the adhesive onto the first adhesive application point through the adhesive sprayer 122, thereby achieving the supply of adhesive to the first adhesive application point.

[0067] like Figure 1 As shown, in one feasible embodiment, the first dispensing tube assembly 12 further includes a filter adjustment device 123, which is disposed on the first pipe 121 and located between the glue sprayer 122 and the first glue tank 111.

[0068] In this technical solution, the filter regulating device 123 is installed at the inlet end of the glue sprayer 122. The glue liquid is filtered by the filter regulating device 123, and the pressure and flow rate of the glue liquid in the first pipe 121 are controlled to deliver glue liquid with stable parameters to the glue sprayer 122, prevent the glue sprayer 122 from being blocked, and improve the uniformity of glue supply from the glue sprayer 122.

[0069] Furthermore, the filtration and adjustment device 123 includes a filter and a regulator. The filter filters out impurities in the adhesive liquid to prevent the glue sprayer 122 from becoming clogged or the adhesive supply from being uneven, while also extending the service life of the pump valve. The regulator controls the pressure and flow rate of the adhesive liquid in the first pipeline 121 to ensure that the adhesive liquid is delivered to the glue sprayer 122 with stable parameters, thus ensuring that the glue sprayer 122 is stably spraying adhesive at the first application point.

[0070] like Figure 1 As shown, in one feasible embodiment, the glue supply system further includes: a second glue pump 16, the drive end of the second glue pump 16 being connected to the second air blowing pipe assembly 142, the first end of the second glue pump 16 being connected to the second glue tank 112, and the second end of the second glue pump 16 being connected to the second glue outlet pipe assembly 13, so as to send the glue in the second glue tank 112 into the second glue outlet pipe assembly 13 through the second glue pump 16.

[0071] In this technical solution, a second glue pump 16 is provided on the second glue dispensing tube assembly 13. The second glue pump 16 is driven by compressed air blown out by the second air blowing tube assembly 142. The glue in the second glue tank 112 is sucked into the second glue dispensing tube assembly 13 by the second glue pump 16, and the amount of glue entering the second glue dispensing tube assembly 13 is controlled by the second glue pump 16.

[0072] Furthermore, the second adhesive pump 16 is a diaphragm pump. The second adhesive pump 16 has a built-in second suction tube. The second adhesive pump 16 is driven by the compressed air discharged from the second air blowing tube assembly 142, and then draws out the adhesive in the second glue tank 112 through the second suction tube inside the second adhesive pump 16 and delivers it to the second glue outlet tube assembly 13.

[0073] like Figure 1 As shown, in one feasible embodiment, the second dispensing tube assembly 13 includes: a second pipe 131, a roller 132, and a glue reservoir 133; the first end of the second pipe 131 is connected to the second glue tank 112, and the second end of the second pipe 131 extends to the second glue application point; the roller 132 is disposed at the second end of the second pipe 131, and the roller 132 applies glue to the second glue application point by roller application of glue liquid; the glue reservoir 133 is disposed on the second pipe 131, and the glue reservoir 133 is located between the roller 132 and the second glue tank 112.

[0074] In this technical solution, the second adhesive pump 16 is installed on the second pipe 131. The second adhesive pump 16 transports the adhesive in the second adhesive tank 112 to the roller 132 through the second pipe 131. The roller 132 then applies adhesive to the second adhesive application point, thus supplying adhesive to the second adhesive application point. By installing an adhesive reservoir 133 on the second pipe 131, the adhesive entering the second pipe 131 is temporarily stored, stabilizing the pressure change of the adhesive in the second pipe 131. This helps to improve the stability and uniformity of the adhesive supply from the roller 132.

[0075] It should be noted that the original YP418 hard box packaging machine's glue supply system uses two glue outlet pipes on the glue reservoir 133 to distribute the glue stored in the reservoir 133 to two glue application points for glue supply. This application eliminates one glue outlet pipe of the glue reservoir 133 and adds a second glue tank 112 and a second glue outlet pipe assembly 13, making the glue supply pipe of the second glue application point independent of the first glue application point. This results in less modification to the original structure of the YP418 hard box packaging machine, simpler operation, and less engineering work. At the same time, it also enables the glue supply of the first and second glue application points to be controlled separately, thereby achieving precise glue supply to the first and second glue application points.

[0076] like Figure 1As shown, in one feasible embodiment, the air supply system 14 further includes: an air source 143 and a pneumatic diaphragm valve 144; the first output end of the air source 143 is connected to the first air blowing pipe 141, and the second output end of the air source 143 is connected to the second air blowing pipe assembly 142; the pneumatic diaphragm valve 144 is disposed on the second pipe 131, and the pneumatic diaphragm valve 144 is located between the glue reservoir 133 and the glue roller 132; the second air blowing pipe assembly 142 includes a second air blowing pipe 1421 and a pressure regulating valve 1422, the pressure regulating valve 1422... The pressure regulating valve 1422 is installed on the second air blowing pipe 1421. The input end of the pressure regulating valve 1422 is connected to the air source 143, and the first output end of the pressure regulating valve 1422 is connected to the second glue tank 112 to force the glue in the second glue tank 112 into the second glue outlet assembly 13. The second output end of the pressure regulating valve 1422 is connected to the pneumatic diaphragm valve 144 to input gas into the pneumatic diaphragm valve 144 and drive the pneumatic diaphragm valve 144. The pneumatic diaphragm valve 144 is equipped with a solenoid valve 145, which controls the pneumatic diaphragm valve 144.

[0077] In this technical solution, the air source 143 supplies air to the first air blowing pipe 141 and the second air blowing pipe assembly 142; the air source 143 supplies air to the first glue container 111 through the first air blowing pipe 141 to force the glue in the first glue container 111 into the first glue outlet assembly 12; when the air source 143 supplies air to the second air blowing pipe assembly 142, the first output end of the pressure regulating valve 1422 is the first output end of the second air blowing pipe assembly 142, and the second output end of the pressure regulating valve 1422 is the second output end of the second air blowing pipe assembly 142; the second output end of the second air blowing pipe assembly 142 is connected to the pneumatic diaphragm valve 144 to allow for the flow of air through the pneumatic diaphragm valve 144. The second air blowing pipe assembly 142 drives the pneumatic diaphragm valve 144, and the solenoid valve 145 is used to control the pneumatic diaphragm valve 144. The pneumatic diaphragm valve 144 is installed on the second pipe 131 between the roller gluer 132 and the glue reservoir 133. After the glue reaches the glue reservoir 133, the pneumatic diaphragm valve 144 precisely controls the flow rate of the glue entering the roller gluer 132 from the glue reservoir 133, thereby accurately supplying glue to the second glue application point. The pressure of the compressed gas entering the second glue tank 112 is adjusted by the first output end of the pressure regulating valve 1422 to precisely control the flow rate of the glue flowing from the second glue tank 112 to the second glue outlet pipe assembly 13.

[0078] It is understandable that the first output end of the pressure regulating valve 1422 is used to drive the second glue pump 16, and the flow rate of glue from the second glue tank 112 to the second glue dispensing tube assembly 13 is controlled by controlling the second glue pump 16; the air source 143 supplies air to the first air blowing tube 141, drives the first glue pump 15, and the flow rate of glue from the second glue tank 112 to the second glue dispensing tube assembly 13 is controlled by the first glue pump 15.

[0079] Furthermore, a pressure regulating device is provided on the first air blowing pipe 141 to control the driving pressure of the first adhesive pump 15.

[0080] Specifically, the pressure regulating valve 1422 is a pneumatic pressure regulating valve, driven by the gas discharged from the second air blowing pipe 1421.
