[0002] When packaging small cigarette packs into cartons, glue needs to be sprayed onto the wrapping paper. In actual production, the cigarette cartons are transported via a conveyor belt to a gluing station equipped with a glue valve. This valve is connected to a barrel of glue liquid and sprays it onto the wrapping paper. However, existing glue spraying devices often experience glue breakage during use, impacting the quality of the cigarette cartons. Utility Model Content

[0003] The purpose of the present invention is to solve the problem that existing glue spraying devices often break glue, which affects the packaging quality of cigarette cartons. The present invention provides a glue spraying device that can effectively avoid the problem of glue breaking, thereby improving the packaging quality of cigarette cartons.

[0004] The inventors discovered that existing glue spraying devices often experience glue breakage due to the composition of the glue. When the glue spraying device is not in operation, the glue liquid in the glue feed pipe will not flow for a short period of time, resulting in particles or glue lumps. When the glue spraying device is activated again, these particles or glue lumps will flow to the glue nozzle, causing the nozzle to clog and resulting in glue breakage on the wrapping paper, thus affecting the quality of cigarette packaging.

[0010] By adopting the above technical solution, by connecting the glue delivery tube to the vibration mechanism, the glue delivery tube can produce a small range of vibration under the drive of the vibration mechanism, thereby causing the glue liquid in the glue delivery tube to vibrate, and then evacuate the accumulated particles or glue blocks, thereby preventing the glue spray valve from being blocked and improving the quality of cigarette packaging.

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1As shown, an embodiment of the present utility model discloses a glue spraying device for spraying glue onto cigarette packaging paper 14, and the glue spraying device includes: a glue barrel 1, a glue feeding pipe 3, a hose 4, a glue spraying valve 6 and a vibration mechanism. Among them, a cavity is provided in the glue barrel 1, and the cavity is used to contain the glue liquid. The glue barrel 1 is provided with a glue inlet 15 and a glue outlet 2. Specifically, the glue inlet 15 is provided at the top of the glue barrel 1, and the glue liquid enters the cavity through the glue inlet 15. The glue outlet 2 is provided at the bottom of the glue barrel 1, and the glue liquid flows out from the glue outlet 2. One end of the glue feeding pipe 3 is connected to the glue outlet 2 through the hose 4, and the other end of the glue feeding pipe 3 is closed. The glue feeding pipe 3 is provided with at least two glue spraying ports 5, and each glue spraying port 5 is along the extension direction of the glue feeding pipe 3 (such as Figure 1 The glue feeding pipe 3 is preferably made of stainless steel. The number of the glue spray valves 6 is equal to the number of the glue spray ports 5, and each glue spray port 5 is provided with a glue spray valve 6, which is used to control the opening and closing of the glue spray port 5. In this embodiment, the number of the glue spray valves 6 and the glue spray ports 5 are both six, and the six glue spray ports 5 are evenly spaced along the extension direction of the glue feeding pipe 3, and each glue spray port 5 is connected to a glue spray valve 6. The glue liquid flows through the glue outlet 2, the hose 4, the glue feeding pipe 3, and the glue spray port 5 in sequence before arriving at the glue spray valve 6. When the glue spray valve 6 is opened, the glue liquid is sprayed from the glue spray valve 6 to be coated on the cigarette wrapping paper 14 near it. A vibration mechanism is connected to the glue feeding pipe 3, and the vibration mechanism can cause the glue feeding pipe 3 to vibrate. In this embodiment, the structure and form of the vibration mechanism are not limited, and any mechanism that can cause the glue feeding pipe 3 to vibrate is within the scope of protection of this application. For example, the vibration mechanism may be an eccentric motor, a motor, an ultrasonic vibration mechanism or the like.

[0029] By adopting the above technical solution, by connecting the glue feeding tube 3 with the vibration mechanism, the glue feeding tube 3 can generate a small range of vibration under the drive of the vibration mechanism, thereby causing the glue liquid in the glue feeding tube 3 to vibrate, and then evacuate the accumulated particles or glue blocks, thereby preventing the glue spray valve 6 from being blocked and improving the quality of cigarette packaging.

[0030] Furthermore, the inventors considered that there is a ejector pin in the glue spray valve 6, which is made of ceramic material, and the vibration amplitude of the eccentric motor and the motor is too large, which can easily cause damage to the ejector pin. Therefore, in this embodiment, the vibration mechanism is preferably an ultrasonic vibration mechanism 7. Figure 1 As shown, the ultrasonic vibration mechanism 7 includes a generator 71 and a transducer 72, and the generator 71 is electrically connected to the transducer 72. The transducer 72 is provided on the glue feeding tube 3 and is used to convert the electrical energy generated by the generator 71 into mechanical vibration to vibrate the glue feeding tube 3.

[0031] Alternatively, as Figure 1As shown, the transducer 72 is arranged in the middle of the glue feeding tube 3, that is, the transducer 72 is arranged in the center relative to the glue feeding tube 3, so that the amplitudes at both ends of the glue feeding tube 3 can be relatively consistent, thereby improving the uniformity of the glue liquid.

[0032] Optionally, the operating frequency range of the generator 71 is 2000 Hz to 4000 Hz. The inventors have determined through multiple tests that when the operating frequency range of the generator 71 is 2000 Hz to 4000 Hz, the vibration generated by the transducer 72 is just enough to disperse particles or glue lumps accumulated in the glue delivery tube 3 without damaging parts such as the glue spray valve 6 due to excessive vibration.

[0033] Alternatively, as Figure 1 As shown, the glue spraying device further includes a support member 8, on which the glue feeding tube 3 is placed. The support member 8 is used to provide upward support for the glue feeding tube 3 to improve the stability of the glue spraying. Furthermore, the support member can be made of a rigid material, such as stainless steel, or an elastic material, such as rubber or a spring.

[0034] Optionally, each glue spraying valve 6 is an electric valve, so that the glue spraying valve 6 can be automatically opened and closed.

[0035] Alternatively, as Figure 1 As shown, each glue spraying valve 6 is provided with a glue spraying station on one side (such as Figure 1 (As shown in area A in the figure), the cigarette wrapping paper 14 is transported by the conveying mechanism 9 to the corresponding glue spraying station. Specifically, the conveying mechanism 9 is a belt conveyor. When each cigarette wrapping paper 14 is transported to the corresponding glue spraying station, the cigarette wrapping paper 14 is located in the spraying area of ​​the glue spraying valve 6. At this time, the ultrasonic vibration mechanism 7 starts to work, the glue feeding pipe 3 starts to vibrate, and at the same time, each glue spraying valve 6 opens to spray glue onto the cigarette wrapping paper 14. When the glue spraying is completed, the ultrasonic vibration mechanism 7 stops working, the glue spraying valves 6 are closed, and the belt conveyor transports the cigarette wrapping paper 14 to the next process.

[0036] Optionally, the glue spraying device disclosed in the present application also includes a control system, which is electrically connected to each glue spraying valve 6, ultrasonic vibration mechanism 7 and conveying mechanism 9 respectively; when the conveying mechanism 9 is running, the control system controls the ultrasonic vibration mechanism 7 to work and controls each glue spraying valve 6 to open, and each glue spraying valve 6 sprays glue to the cigarette packaging paper 14 corresponding to the glue spraying station; when the conveying mechanism 9 stops running, the control system controls the ultrasonic vibration mechanism 7 to stop working and controls each glue spraying valve 6 to close. By setting up a control system, the automation level of the glue spraying process can be improved.

[0037] Optionally, the cavity of the glue barrel 1 is a sealed cavity, specifically, Figure 1As shown, a sealing cover 16 is provided on the glue inlet 15 to seal the cavity in the glue barrel 1. Since the glue liquid has a certain viscosity, the glue barrel 1 of the present application is also provided with a compressed air inlet 10 and an air inlet pipe 11. The compressed air inlet 10 is provided at the top of the glue barrel 1. One end of the air inlet pipe 11 is connected to the compressed air inlet 10, and the other end of the air inlet pipe 11 is connected to an air source 12. The air source 12 is a high-pressure air source and can be provided by a fan. Compressed air enters the glue barrel 1 through the compressed air inlet 10.

[0038] By adopting the above technical solution, the air pressure in the glue barrel 1 can be increased by introducing compressed air into the glue barrel 1, thereby ensuring that the glue liquid in the glue barrel 1 continues to enter the glue spray valve 6 under the action of pressure, thereby preventing glue breakage due to low air pressure, and thus improving the packaging quality of cigarettes.

[0039] Alternatively, as Figure 1 As shown, the glue spraying device disclosed in the present application further includes a manual valve 13, which is provided on the air inlet pipe 11. The manual valve 13 is used to control the opening and closing of the air inlet pipe 11. The provision of the manual valve 13 can facilitate the operator to adjust the opening and closing of the air inlet pipe 11 according to actual conditions, thereby improving the convenience of use of the device.

[0040] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above description is provided to further illustrate the present invention in conjunction with specific embodiments, and that the present invention should not be construed as being limited to these descriptions. Those skilled in the art may make various changes in form and detail, including simple deductions or substitutions, without departing from the spirit and scope of the present invention.
