[0002] In the field of cigarette making machine production, electronic glue spraying technology is a commonly used technology and equipment; a conventional electronic glue spraying device includes a spray gun, kraft paper and a glue scraper head. When the electronic glue spraying device is spraying glue, the glue from the spray gun enters the glue scraper head, the kraft paper and the glue scraper head come into contact, forming glue coating on different types of kraft paper.

[0003] However, there is an uneven problem when the glue of electronic glue spraying is transferred to the tipping paper through the spray gun; because the amount of glue sprayed by each spray gun is uneven, different thicknesses of glue layers will be produced on the tipping paper, and because the glue layer is white, the amount of glue cannot be perceived or defined visually; the amount of glue on the tipping paper has an important impact on the wrapping of cigarettes. If there is too much glue, it is not easy to dry and bond, and the cigarettes will have quality defects such as air leakage and wrinkles. If there is too little glue, it is not easy to bond, and the cigarettes will have flanging and warping, blocking the equipment conveying channel. If the glue is unevenly distributed, it will not only produce the above two problematic cigarettes, but also affect the key indicator of the cigarette, the ventilation of the mouthpiece, and fail to meet the physical indicators of high-quality products.

[0015] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0016] The application principle of the present invention is described in detail below in conjunction with the accompanying drawings.

[0017] Example 1 like Figure 1 As shown, an embodiment of the present invention provides a method for defining the glue coating amount of an electronic glue spraying machine, comprising the following steps: S01: Obtaining a preset spray gun pressure, a preset glue coating amount and a spraying time corresponding to the spray gun; S02: Under the condition that the preset spray gun pressure is constant, the electronic glue spraying device of the cigarette making machine is controlled to spray glue to produce glue, the glue is weighed by the electronic glue spraying branch glue weighing device, and the valve opening of the spray gun is calibrated based on the comparison result between the weighing result and the preset glue amount to obtain the calibrated valve opening; S03: When the calibrated valve opening is constant, the electronic glue spraying device of the cigarette making machine is controlled to spray glue to produce glue, the glue is weighed by the electronic glue spraying branch glue weighing device, and the spray gun pressure is calibrated based on the comparison result between the weighing result and the preset glue amount to obtain the calibrated spray gun pressure; S04: Define the glue application amount of the spray gun based on the calibrated valve opening and the calibrated spray gun pressure.

[0018] The method for defining the glue amount of electronic glue spraying in a cigarette making machine proposed in the present invention controls the electronic glue spraying device of the cigarette making machine to spray glue to produce glue, utilizes the electronic glue spraying branch glue weighing device to weigh the glue, and based on the comparison result between the weighing result and the preset glue amount, sequentially performs valve opening calibration and spray gun pressure calibration on the glue sprayed from the spray gun, thereby quantifying the glue amount to a fixed valve opening spray gun pressure, thereby realizing the quantitative perception and definition of the glue amount on the tipping paper, and avoiding the problem of uneven glue coating on the tipping paper.

[0019] In this embodiment, if Figure 2 As shown, the electronic glue spraying device of the cigarette making machine adopts the glue spraying device of the connecting machine disclosed in patent CN 118060103 A, which is composed of 5 spray guns (first spray gun 1, second spray gun 2, third spray gun 3, fourth spray gun 4, fifth spray gun 5) installed on the base 10, and glue with fixed pressure is input by the glue supply hose 6. After control, the glue of the spray gun enters the glue scraping head 7, and the tipping paper 8 contacts the glue scraping head 7. In the process of continuous forward movement, glue is applied on the surface of the tipping paper 8. By controlling the second spray gun 2 and the fourth spray gun 4 at a certain frequency, a glue-free area 9 can also be formed on the tipping paper 8 to meet the production requirements of some cigarette brands.

[0020] Among them, the structure of the spray gun is as follows Figure 3 As shown, the spray gun includes an electromagnetic coil 11, a nozzle scraper head (glue scraper head) 7, an ejector pin 13, a reset spring 14, a gun seat 12 and other parts. When not in use, the ejector pin 13 will be pressed against the nozzle base under the restoring force of the reset spring 14, and the nozzle is in a closed state, blocking the outflow of glue. When the spray gun is in operation, the coil is energized to generate an electromagnetic effect, pulling the ejector pin 13 to move in the opposite direction of the spring force of the reset spring 14. The ejector pin 13 is separated from the ejector pin base, and the glue flows out through the opened hole to the glue scraper head 7. The glue scraper head 7 is in direct contact with the glue-coated surface of the tipping paper 8 to form the glue 19. During the continuous movement of the tipping paper 8, the glue 19 squeezed out by the scraper head is continuously taken away; Then it enters the cutting and wrapping stage, and the cut tipping paper 8 is glued to the cigarette and the mouthpiece, and the wrapping is completed under the action of the equipment. At this time, the amount of glue on the tipping paper has an important influence on the wrapping. If there is too much glue, it will not be easy to dry and stick, and the cigarette will have quality defects such as leakage and wrinkles. If there is too little glue, it will not be easy to stick, and the cigarette will have flanging and warping, blocking the equipment conveying channel. If the glue is unevenly distributed, it will not only produce the above two problematic cigarettes, but also affect the key indicator of the cigarette, the ventilation of the mouthpiece, and fail to meet the physical indicators of high-quality products. Therefore, the perception of the amount of glue (amount of glue) is very important.

[0021] Specifically, when it is found that the glue coating state is not correct during production, the glue coating amount needs to be adjusted. Usually, the glue coating amount can be adjusted by adjusting the spray gun pressure and the spray gun valve opening, as follows: 1) Spray gun valve opening: The principle of this adjustment is to adjust the opening distance of the ejector pin (the cross section through which the liquid flows) to control the flow rate of glue per unit time, thereby controlling the amount of glue applied.

[0022] 2) Spray gun pressure: The amount of glue applied can be adjusted by adjusting the output pressure of the spray gun piston pump. The principle of this adjustment is that the amount of glue applied per unit time can be controlled by adjusting the pressure while the cross-section through which the liquid flows remains unchanged.

[0023] That is, the spray gun valve opening and the spray gun pressure can be used to quantitatively sense the amount of glue applied, thereby avoiding the problem of uneven glue application on the tipping paper.

[0024] In this embodiment, in step S02, under the condition that the preset spray gun pressure is constant, the electronic glue spraying device of the cigarette making machine is controlled to spray glue to produce glue coating, the glue coating is weighed by the electronic glue spraying branch glue weighing device, and the valve opening of the spray gun is calibrated based on the comparison result between the weighing result and the preset glue coating amount to obtain the calibrated valve opening, including: S021: According to a preset spray gun pressure, control the spray gun in the electronic glue spraying device of the cigarette making machine to spray glue, and obtain glue coating under the preset spray gun pressure; S022: Weigh the glue applied under the preset spray gun pressure by using an electronic glue spraying branch connection weighing device to obtain the glue applied amount under the preset spray gun pressure; S023: Compare the glue coating amount under the preset spray gun pressure with the preset glue coating amount to obtain a first comparison result; S024: According to the first comparison result, the valve opening of the spray gun is adjusted; specifically, when the amount of glue applied under the preset spray gun pressure is greater than the preset amount of glue applied, the valve opening of the spray gun is reduced; when the amount of glue applied under the preset spray gun pressure is less than the preset amount of glue applied, the valve opening of the spray gun is increased.

[0025] S025: Repeat S021 to S024 until the glue coating amount under the preset spray gun pressure is consistent with the preset glue coating amount, and the adjusted valve opening is the calibrated valve opening.

[0026] In this embodiment, in step S03, when the calibrated valve opening is constant, the electronic glue spraying device of the cigarette making machine is controlled to spray glue to produce glue, the glue is weighed by the electronic glue spraying branch glue weighing device, and the spray gun pressure calibration process is performed based on the comparison result between the weighing result and the preset glue amount to obtain the calibrated spray gun pressure, which specifically includes: S031: According to the calibrated valve opening, control the spray gun in the electronic glue spraying device of the cigarette making machine to spray glue, and obtain the glue coating under the calibrated valve opening; S032: Weigh the glue applied under the calibrated spray gun pressure using an electronic glue spraying branch connection weighing device to obtain the glue applied under the calibrated spray gun pressure; S033: Compare the glue application amount under the calibrated valve opening with the preset glue application amount to obtain a second comparison result; specifically, when the glue application amount under the calibrated valve opening is greater than the preset glue application amount, reduce the spray gun pressure; when the glue application amount under the calibrated valve opening is less than the preset glue application amount, increase the spray gun pressure.

[0027] S034: adjusting the spray gun pressure according to the second comparison result; S035: Repeat S031 to S034 until the glue coating amount under the calibrated valve opening is consistent with the preset glue coating amount, and the adjusted spray gun pressure is the calibrated spray gun pressure.

[0028] Specifically, when the glue spray gun pressure is determined, the valve opening is linearly related to the output glue amount, thereby calibrating the valve opening of the spray gun; after the valve opening is fixed, the spray gun pressure is linearly related to the output glue amount, thereby calibrating the pressure of the spray gun; after two calibrations, the glue amount per unit time can be controlled, and the ratio of glue pressure (spray gun pressure) to glue amount is fixed, thereby quantitatively defining the glue amount.

[0029] Example 2 The present invention provides a system for defining the amount of glue applied by electronic glue spraying of a cigarette making machine, comprising: a host computer, an electronic glue spraying device of the cigarette making machine, a glue connection weighing device for a branch line of electronic glue spraying and a controller; the host computer is connected to the controller and is used to input a preset spray gun pressure, a preset glue application amount and a glue spraying time corresponding to the spray gun, and transmit them to the controller; the electronic glue spraying device of the cigarette making machine and the glue connection weighing device for the branch line of electronic glue spraying are respectively connected to the controller; the controller is used to implement the method for defining the amount of glue applied by electronic glue spraying of a cigarette making machine described in Example 1.

[0030] Specifically, the electronic glue spraying device of the cigarette making machine comprises: a plurality of spray guns, a glue supply pipe 6 and a glue scraping head 7 installed on a base.

[0031] Specifically, the electronic glue spraying branch glue connecting and weighing device is used to receive and weigh the glue sprayed by the electronic glue spraying device of the cigarette making machine, and includes: a water box base 16, a weighing base 17 fixed on the water box base 16, a mounting block 18 fixed on the weighing base 17, a weighing sensor 19, and a weighing box 20 corresponding to the spray gun in the electronic glue spraying device of the cigarette making machine; the weighing sensor 19 is placed at a fixed position on the weighing base 17; the weighing box 20 is placed on the mounting block 18, and is used to receive the glue sprayed by the spray gun.

[0032] When defining the glue coating amount, the water box (the water box in the original electronic glue spraying device) can be removed, and the electronic glue spraying branch glue connection weighing device can be installed. Five weighing boxes 20 are installed on the weighing device, corresponding to the five spray guns of the electronic glue spraying device. The weighing boxes 20 are placed on the mounting block 18, and the mounting block 18 is fixed on the weighing base 17. The corresponding position of the weighing box 20 on the weighing base 17 is installed with a weighing sensor 19, which can directly collect and feedback the glue coating amount on the human-machine interface through the change of the electrical signal caused by the weight change.

[0033] Specifically, relevant function buttons are developed on the host computer, which are divided into three parts: valve opening calibration, spray gun pressure calibration, and operation process. The valve opening calibration is used to calibrate the valve opening by quantitatively applying glue under standard pressure (preset spray gun pressure). The spray gun pressure calibration is used to calibrate the pressure after the valve opening is determined to ensure the glue output per unit time during production. The buttons in the operation process are used to start / end the process, and to display and reset the feedback weight of the weighing device.
