[0002] Most of the outer packaging of cigarette products is glued. There are two ways to apply glue: gluing with a glue wheel or contactless glue spraying. Since contactless glue spraying has the advantages of precise gluing points, uniform gluing, and fast gluing speed, it can be more widely used in modern cigarette machine equipment. Generally speaking, the glue spraying device generally includes a glue pump, a high-pressure glue delivery pipeline, a voltage stabilizing mechanism, a distributor, a spray gun, a glue spray nozzle and other components. Since the glue is placed for a long time, the water is lost after mixing with the air, and the glue is easily dried. It is also possible that the glue spraying device is easily blocked due to impurities in the glue, long maintenance downtime, dust and droplets in the air, etc., and regular cleaning and maintenance are required. The cleaning method in the prior art can only be to disassemble the parts and clean them one by one in a dedicated cleaning room. Cleaning is time-consuming and inefficient. In addition, the maintenance quality of the parts after cleaning and maintenance, such as the voltage stabilizing mechanism and the spray gun, cannot be tested separately, and can only be tested on the machine. If there is a problem, it must be disassembled again for secondary maintenance, which is troublesome. Utility Model Content

[0028] Example 1

[0029] like Figure 1 to Figure 2The first embodiment of the cleaning and testing platform of the glue spraying device of the utility model is shown. The platform is applied to the glue spraying device, which at least includes: a pressure stabilizing mechanism 3 for adjusting the glue spraying pressure; a spray gun 6 for spraying glue, and the glue flows into the spray gun 6 after passing through the pressure stabilizing mechanism 3 and is sprayed out from the spray gun 6; the platform includes: a raw material storage mechanism 1 for storing a cleaning solution or a testing solution; a power mechanism 2 for providing suction and transportation power so that the cleaning solution or the testing solution can enter the spray gun 6 from the raw material storage mechanism 1, and one end of the power mechanism 2 is connected to the raw material storage mechanism 1, and the other end is connected to the stabilizing mechanism 2. The power mechanism 2, the pressure detector 4 and the spray gun 6 are all connected to the controller 8 for communication; the cleaning solution or the detection solution flows from the raw material storage mechanism 1 through the power mechanism 2, the pressure stabilizing mechanism 3, the pressure detector 4 and the spray gun 6 in sequence and then reaches the waste storage mechanism 7.

[0030] The raw material storage mechanism 1 can have the function of storing the cleaning solution and the detection solution at the same time, which can be achieved by setting two different accommodating chambers, or it can have only one accommodating chamber, and the cleaning solution is placed in the raw material storage mechanism 1 during the cleaning process, and the detection solution is placed in the raw material storage mechanism 1 during the detection process to achieve the corresponding functions. The controller 8 can control the operation of the power mechanism 2, the pressure detector 4, and the spray gun 6.

[0031] As an embodiment of the present invention, it further includes a liquid level monitoring mechanism 9 , which is movably mounted on the raw material storage mechanism 1 and is in communication connection with the controller 8 .

[0032] The liquid level monitoring mechanism 9 is used to monitor the liquid level of the cleaning solution or the detection solution in the raw material storage mechanism 1 to prevent the raw material from being exhausted, causing vacuum suction of the power mechanism 2 and damaging the performance of the power mechanism 2 .

[0033] As an embodiment of the present utility model, the liquid level monitoring mechanism 9 includes a liquid level sensor 91, a fixed rod 92, and a float 93. The liquid level sensor 91 is installed on the fixed rod 92 and is communicated with the controller 8. The end of the fixed rod 92 protrudes from the raw material storage mechanism 1 and is deeply arranged in the raw material storage mechanism 1. The float 93 floats on the solution surface in the raw material storage mechanism 1 and is movably mounted on the fixed rod 92. The liquid level sensor 91 is inductively connected to the float 93.

[0034] The float 93 is used to follow the liquid level fluctuation of the raw material, ie, the cleaning solution or the detection solution, in the raw material storage mechanism 1 , and the liquid level sensor 91 on the fixed rod 92 is sensed by the float 93 to obtain the liquid level change of the raw material.

[0035] As an embodiment of the present invention, the liquid level sensor 91 is a magnetic displacement sensor, and the float 93 is made of metal material.

[0036] Using a magnetic displacement sensor to achieve inductive connection with a float 93 made of a metal material is one implementation method. Within the knowledge of those skilled in the art, the inductive connection between the liquid level sensor 91 and the float 93 can also be achieved through other structures.

[0038] The detachable connection between the cover 11 and the barrel 12 can facilitate the injection of the cleaning solution and the detection solution, and can also facilitate the cleaning of the barrel 12. The fixed rod 92 can be used as a reference for the liquid level. The fixed rod 92 can be used to grasp the capacity of the barrel 12 as a whole, similar to a ruler. When the float 93 is located at the bottom of the fixed rod 92, it means that the liquid level is low, and when the float 93 is located at the upper part of the fixed rod 92, it means that the liquid level is high.

[0039] The power mechanism 2 includes a high-pressure pump 22 and an air pressure regulating valve 21, the air outlet of the air pressure regulating valve 21 is connected to the air inlet of the high-pressure pump 22, and the high-pressure pump 22 and the air pressure regulating valve 21 are both communicatively connected to the controller 8. The air pressure regulating valve 21 can adjust the pressure by adjusting the amount of air entering the high-pressure pump 22, thereby realizing the control of the power.

[0040] As an embodiment of the present invention, a display screen is installed on the controller 8. The display screen can make the control information more intuitive, such as the pressure comparison result of the pressure stabilizing mechanism 3 can be more clearly presented through the display screen, and the liquid level of the raw material in the raw material storage mechanism 1 can also be more intuitively presented.

[0041] As an embodiment of the present invention, the spray gun 6 is a contactless point spray gun. The contactless point spray gun has the advantages of precise gluing points, uniform gluing, and fast gluing speed, and can be better applied in modern smoke exhaust hood equipment.

[0042] like Figure 1As shown, the raw material storage mechanism 1 and the waste material storage mechanism 7 are placed on the ground. A cover 11 and a liquid level sensor 91 are installed above the barrel 12 of the raw material storage mechanism 1. The liquid level sensor 91 is arranged along the length direction of the fixed rod 92. The liquid level sensor 91 transmits the liquid level signal in the raw material storage mechanism 1 to the controller 8 and displays the liquid level information on the LCD screen. One end of the conveying pipeline is connected to the raw material storage mechanism 1, and the other end is connected to the inlet of the high-pressure pump 22. Preferably, the model of the high-pressure pump 22 is a HHS KPE-9 piston pump, which is a proportional amplification pump. The air outlet of the air pressure regulating valve 21 is connected to the air inlet of the high-pressure pump 22 and is fixed to the bracket together with the high-pressure pump 22. The bracket is fixed to the shell of the detection platform. The glue outlet of the high-pressure pump 22 is connected to the inlet end of the pressure stabilizing mechanism 3, and the pressure stabilizing mechanism 3 is also fixed to the bracket. The glue outlet of the pressure stabilizing mechanism 3 is connected to the distributor 5 through a pipeline, and the distributor 5 is connected to the spray gun 6 through a pipeline. Preferably, the spray gun 6 is of model DDL500, which is a contactless point spray gun. The spray gun 6 is located above the waste storage mechanism 7 .

[0043] The cleaning and testing platform of the glue spraying device of the utility model mainly includes the following functions: a cleaning function, a testing function, and a liquid level display function.

[0044] (1) When the cleaning function is turned on, 2 / 3 of clean water is injected into the raw material storage mechanism 1, the air source is turned on, and the air pressure regulating valve 21 should be connected to an air source of not less than 6 bar. At the same time, the air pressure is adjusted to 4-5 bar. The controller 8 sends a signal to the high-pressure pump 22, and the high-pressure pump 22 starts to work. The high-pressure pump 22 is a proportional amplification pump, model HHS KPE-9 piston pump, and its output pressure is 9 times the air source input pressure, that is, the glue pressure can reach 36-45 bar. The high-pressure water passes through the pipeline, flows through the pressure stabilizing mechanism 3, the distributor 5 and the spray gun 6, and is discharged into the waste storage mechanism 7. The cleaning flow and cleaning time are set by the internal program. After the glue inside the pressure stabilizing mechanism 3 and the spray gun 6 is completely cleaned, the cleaning function is turned off.

[0045] (2) The detection function mentioned in the present invention is mainly to detect the effectiveness of the pressure stabilizing device and the effectiveness of the nozzle of the spray gun 6. When the detection function is turned on, 2 / 3 of the water-soluble glue is injected into the raw material storage mechanism 1, the air source is turned on, and the air pressure regulating valve 21 should be connected to the air source of not less than 6 bar. At the same time, the air pressure is adjusted to 4-5 bar. The controller 8 sends a signal to the high-pressure pump 22, and the high-pressure pump 22 starts to work. The outlet pressure of the high-pressure pump 22 reaches 36-45 bar. The high-pressure water-soluble glue passes through the pipeline, flows through the pressure stabilizing mechanism 3, the distributor 5 and the spray gun 6, and is discharged to the waste storage mechanism 7. A pressure detector 4 is installed at the outlet of the pressure stabilizing mechanism 3. The pressure detector 4 converts the glue pressure signal into an electrical signal and transmits it to the controller 8. The preset electronic adjustment value P1 and the actual measured value P2 detected by the pressure detector 4 are displayed on the display screen of the controller 8. By comparing the relative error between P1 and P2, it is determined whether the pressure stabilizing mechanism 3 is effective. The detection of the nozzle of the spray gun 6 is performed by sending a signal to the controller 8 to control the opening and closing function of the nozzle, and judging whether the glue spraying effect of the spray gun 6 is normal by visual observation.

[0046] (3) The liquid level display function is realized by the floating ball 93 and the fixed rod 92 built into the raw material storage mechanism 1. The inner hole of the floating ball 93 is inserted into the fixed rod 92. When the raw material liquid level changes, the position of the floating ball 93 relative to the fixed rod 92 also changes. By detecting the position of the floating ball 93 relative to the fixed rod 92, it can be converted into the liquid level of the raw material, and the converted electrical signal is transmitted to the controller 8 and displayed on the display screen on the controller. When the liquid level in the raw material storage mechanism 1 exceeds or falls below the set level, the controller 8 will automatically sound an alarm through the alarm mechanism and immediately shut down to protect the internal components of the system.

[0047] Example 2

[0048] like Figure 2 The second embodiment of the cleaning and testing platform of a glue spraying device of the utility model is shown. This embodiment is similar to the first embodiment, except that it also includes a distributor 5 and at least two spray guns 6. One end of the distributor 5 is connected to the pressure detector 4, and the other end is connected to different spray guns 6.

[0049] The distributor 5 can be used to distribute the cleaning solution or the detection solution flowing through the power mechanism 2 and the pressure regulating mechanism, so that each spray gun 6 can be cleaned or detected at the same time.

[0050] Example 3

[0051] The following is a third embodiment of a cleaning and detection platform for a glue spraying device of the utility model. This embodiment is similar to the first embodiment, except that it further includes an alarm mechanism, and the alarm mechanism is communicatively connected with the controller 8 .

[0052] The alarm mechanism can be a buzzer or a vibration motor. The alarm mechanism can be used to give an alarm when the raw material liquid level exceeds or falls below a set value. The alarm mechanism can also be set to give an alarm when the platform operates abnormally, thereby protecting the equipment.

[0053] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here.
