Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for cigarette packaging machines, and in particular to a detection and alarm device for preventing glue overflow in cigarette packaging machines. Background Technology

[0002] In the cigarette tipping production process, white glue is typically used to bond the cigarette tipping paper. The equipment used is a glue-applying roller box, which includes a glue cylinder and a glue-applying roller. The glue cylinder holds the white glue, and the glue-applying roller is positioned above the glue cylinder. The circumference of the glue-applying roller has a portion that contacts the glue in the glue cylinder. When the power mechanism of the cigarette machine drives the glue-applying roller to rotate, the glue in the glue cylinder is transferred to the cigarette tipping paper.

[0003] Because the glue cylinder is located below the paper feeding device, operators cannot directly observe the glue level and must rely on a liquid level detection system. In actual production, glue overflow occurs. The main reasons are as follows: First, the surface of the photoelectric switch in the existing liquid level detection system is easily covered with glue and difficult to clean in time. The resulting glue film interferes with the detection signal, leading to inaccurate liquid level judgment. Second, the glue nozzle may not close tightly, causing glue to slowly seep into the glue cylinder even when there is no need for replenishment, ultimately leading to glue overflow. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a glue overflow detection alarm device for cigarette packaging machines, so as to solve the glue overflow problem in the glue cylinder of cigarette packaging machines in the prior art.

[0005] This utility model solves the above-mentioned technical problems through the following technical means: a detection and alarm device for preventing glue overflow in a cigarette packaging machine, including a glue cylinder body with a glue supply nozzle, the glue supply nozzle being connected to a solenoid valve for controlling glue supply, an overflow groove being provided on one side of the top of the glue cylinder body, a high viscosity liquid detector extending into the overflow groove being provided on one side of the overflow groove, and the high viscosity liquid detector being electrically connected to the solenoid valve.

[0006] An overflow port is provided between the overflow trough and the glue cylinder body. The bottom edge of the overflow port has a preset height difference with the maximum working liquid level of the glue cylinder. One side of the overflow port of the overflow trough is inclined to the bottom to form a flow guide slope. The high viscosity liquid detector is located in the overflow trough on the side away from the flow guide slope.

[0007] Optionally, a transparent observation window is provided on the side of the overflow channel away from the glue cylinder body. This allows the operator to visually determine whether the glue level in the glue cylinder body is abnormally high.

[0008] Optionally, the transparent viewing window is provided with scale lines.

[0009] Optionally, the overflow trough is detachably connected to the glue cylinder body. This facilitates the disassembly, cleaning, and maintenance of the overflow trough.

[0010] Optionally, an overflow pipe is provided at the top of the overflow tank. The overflow pipe is used to connect to an external waste glue recycling system, and the height of the overflow pipe is lower than the height of the overflow port. This prevents secondary glue overflow or glue backflow into the glue cylinder body caused by overflow tank overload due to detector failure, thus preventing secondary contamination.

[0011] Optionally, the high-viscosity liquid detector is also connected to an audible and visual alarm device.

[0012] Optionally, both the high-viscosity liquid detector and the solenoid valve are electrically connected to the control system of the cigarette packaging machine. This allows the detection signal from the high-viscosity liquid detector to be converted into a control signal for opening and closing the solenoid valve via the control system.

[0013] The beneficial effects of this utility model are:

[0014] This invention features an overflow trough on one side of the top of the glue cylinder body. A high-viscosity liquid detector, extending into the top of the overflow trough, is electrically connected to a solenoid valve. This combination of the high-viscosity liquid detector and the solenoid valve improves the response speed and accuracy of the glue supply. Simultaneously, the overflow port side of the overflow trough slopes downwards to form a guide slope. The high-viscosity liquid detector is located on the side of the overflow trough away from the guide slope. This guide slope allows the overflowing glue in the overflow trough to accumulate rapidly. When the volume exceeds the high-viscosity liquid detector's level, an alarm signal is triggered, resulting in a faster alarm response. Attached Figure Description

In the description of this utility model, it should be understood that if terms such as "upper", "lower", "left", "right", "front", "rear", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figure, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.

[0022] like Figures 1-4 As shown, this utility model discloses a glue overflow detection and alarm device for a cigarette packaging machine. It includes a glue cylinder body 1 with a glue supply nozzle 11. The glue supply nozzle 11 is connected to a solenoid valve 12 for controlling glue supply. An overflow groove 21 is provided on one side of the top of the glue cylinder body 1. A high-viscosity liquid detector 22 is provided on one side of the overflow groove 21, extending into the overflow groove 21. The high-viscosity liquid detector 22 is electrically connected to the solenoid valve 12. Simultaneously, both the high-viscosity liquid detector 22 and the solenoid valve 12 are electrically connected to the control system (controller) of the cigarette packaging machine. This allows the detection signal from the high-viscosity liquid detector 22 to be converted into a control signal for opening and closing the solenoid valve 12 through the control system. By configuring the high-viscosity liquid detector 22 and the solenoid valve 12, the response speed and accuracy of the glue supply action are improved.

[0023] In this embodiment, an overflow port 23 is provided between the overflow trough 21 and the glue cylinder body 1. The bottom edge height of the overflow port 23 has a preset height difference with the maximum working liquid level height of the glue cylinder. When the glue (white latex is usually used in cigarette factories) in the glue cylinder body 1 is too high, the glue flows into the overflow trough 21 through the overflow port 23. At the same time, one side of the overflow port 23 of the overflow trough 21 is inclined to the bottom to form a guide slope 24. The high viscosity liquid detector 22 is located in the overflow trough 21 on the side away from the guide slope 24. The setting of the guide slope 24 makes the overflow glue in the overflow trough 21 accumulate rapidly. When it exceeds the high viscosity liquid detector 22, an alarm signal is triggered. The alarm signal is used to remind the operator or to cut off the solenoid valve 12 that controls the glue supply in time.

[0024] In this embodiment, as a backup, a transparent observation window 25 is provided on the side of the overflow trough 21 away from the glue cylinder body 1. The transparent observation window 25 is provided with scale lines, so that the operator can visually judge that the glue level in the glue cylinder body 1 is too high through the transparent observation window 25, and thus take emergency measures.

[0025] In this embodiment, the overflow trough 21 is detachably connected to the glue cylinder body 1. For example, the overflow trough 21 can be fixed to the side of the glue cylinder body 1 by clips or bolts, which facilitates the disassembly, cleaning and maintenance of the overflow trough 21.

[0026] In this embodiment, an overflow pipe 26 is provided at the top of the overflow tank 21. The height of the overflow pipe 26 is lower than the height of the overflow port 23. The overflow pipe 26 is used to connect to an external waste glue recycling system. This prevents secondary glue overflow or glue backflow into the glue tank body 1 caused by overload of the overflow tank 21 due to detector failure, thus preventing secondary contamination.

[0027] In this embodiment, the detection alarm module is connected to the existing control system (controller) of the cigarette packaging machine, including a high-viscosity liquid detector 22 and a solenoid valve 12. The high-viscosity liquid detector 22 is also connected to an audible and visual alarm device through the controller. When the controller receives a signal from the high-viscosity liquid detector 22, it controls the audible and visual alarm device to sound an alarm and simultaneously controls the solenoid valve 12 to close, cutting off the supply of glue to the glue cylinder body 1. The audible and visual alarm device is relatively conventional and will not be described in detail here.

[0028] The working principle of this utility model is as follows:

[0029] When using the detection and alarm device of this utility model, when the glue level in the glue cylinder body 1 is too high, the glue flows into the overflow tank through the overflow port 23. The glue flows through the guide slope 24, causing the overflow glue in the overflow tank 21 to accumulate rapidly and the liquid level to rise rapidly. The high viscosity liquid detector 22 is located on the side of the overflow tank 21 away from the guide slope 24. When the high viscosity liquid level is exceeded, an alarm signal is triggered. The alarm signal is used to remind the operator or to cut off the solenoid valve 12 that controls the glue supply in time.

[0030] In addition, due to the principle of communicating vessels, operators can also visually determine the excessive glue level in the glue cylinder body 1 through the transparent observation window 25 on the overflow trough 21, and take emergency measures to deal with extreme situations of electrical component failure.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
