Description

Technical Field

[0001] This invention relates to the field of tobacco production technology, specifically to a dual-channel dry-wet separation refueling device and refueling method for the inner lining paper of small cigarette packs. Background Technology

[0002] During use, the YB45 small box packaging machine generally needs to evenly spray an appropriate amount of lubricating oil (liquid paraffin is generally used as lubricating oil in cigarette factories) onto the surface of the aluminum foil-coated inner liner paper (hereinafter referred to as inner liner paper) to facilitate the folding of the inner liner paper and thus ensure the quality stability of the cigarettes packaged with the inner liner paper.

[0003] Currently, there are two methods for applying liquid paraffin: manual spraying and automatic spraying. In manual spraying, the operator uses an oil can to apply liquid paraffin to the felt block that is in close contact with the inner lining paper. The felt has a dense structure and small pores, allowing the liquid paraffin to be absorbed, soaked, slowly diffused, and slightly overflowing. Finally, it is carried away by the inner lining paper through friction, thus achieving the function of applying liquid paraffin to the inner lining paper. Manual spraying has the following drawbacks: ① The amount of liquid paraffin added each time varies depending on the operator, making consistency difficult to guarantee. If too much is added at once, excessive paraffin overflow will occur, contaminating the inner lining paper and cigarettes, resulting in waste. This is a serious defect, and if it enters the market, it will have a severe impact. ② The time interval between two applications varies depending on the operator. Too short an interval can easily cause excessive paraffin overflow, while too long an interval can easily lead to insufficient lubrication of the inner lining paper, affecting the packaging quality.

[0004] To avoid the aforementioned problems, most YB45 small box packaging machines are equipped with automatic refueling devices. After years of use, the following drawbacks of these automatic refueling devices have been identified: ① The electrical control module (dry) and refueling control module (wet) of the refueling machine are integrated into one housing, without separation of dry and wet components. During refueling, liquid paraffin easily splashes, contaminating electronic components and accelerating their aging, causing the refueling machine to malfunction and reducing its lifespan (far shorter than the lifespan of the YB45 small box packaging machine's electrical control system); ② The refueling machine generally uses a circuit board (microcontroller) as the control unit and employs a 2032 button battery to store the refueling machine's settings. When the battery is low, the refueling machine lacks an alarm function, and the settings are lost, preventing normal operation; ③ The refueling machine's refueling pipeline lacks an automatic venting device.

[0005] If too much air gets into the fuel line, it can cause the amount of fuel dispensed to fluctuate, affecting the refueling effect. Summary of the Invention

[0006] This invention proposes a dual-channel dry-wet separation refilling device and method for the inner lining paper of small cigarette packs, aiming to partially solve the problems of existing technologies. The specific technical solution is as follows:

[0007] On one hand, a dual-channel dry-wet separation oiling device for the inner lining paper of small cigarette packs is proposed. The oiling device is used to spray oil onto the felt that is in precise contact with the inner lining paper of the cigarette pack, thereby indirectly oiling the inner lining paper of the cigarette pack. The oiling device includes:

[0008] The refueling module and the refueling electrical control module are used to control the refueling module to perform refueling operations. The refueling electrical control module uses a programmable logic controller as the control unit, or it uses a combination of a counter and an electronic time relay as the control unit.

[0009] The compartment is divided into a dry chamber and a wet chamber. The dry chamber houses the refueling electrical control module, while the wet chamber houses the refueling module. The refueling module includes a refueling machine with a left refueling line and a right refueling line connected to its two sides. The left refueling line connects to the left refueling point, and the right refueling line connects to the right refueling point. The left and right refueling lines are equipped with an exhaust valve, a refueling valve, and a line switch valve, respectively. The refueling machine includes an oil mist lubricator connected to a first air valve, which is connected to an external air compressor. The first air valve controls the intake of compressed air into the oil mist lubricator.

[0010] The control panel, located on the outer wall of the partitioned enclosure, integrates a high-speed counter adjustment knob, a time relay adjustment knob, a manual refueling button, and a side selection knob.

[0011] As a preferred technical solution, liquid paraffin is installed in the oil mist lubricator, and the oiling valve is used to control the opening or closing of the oiling point and control the output of liquid paraffin to the felt.

[0012] As a preferred technical solution, the exhaust valve is located on the pipeline between the refueling valve and the pipeline switch valve.

[0013] As a preferred technical solution, two independent valve groups are installed side by side in the wet chamber, each valve group including an exhaust valve, a refueling valve and a pipeline switch valve.

[0014] As a preferred technical solution, when a programmable logic controller (PLC) is used as the control unit, the parameters are stored in the non-volatile memory of the PLC; when a combination of a high-speed counter and an electronic time relay is used as the control unit, the parameters are set by a mechanical knob and do not require battery storage.

[0015] As a preferred technical solution, the volume of the dry chamber is larger than that of the wet chamber, and the partitioned chamber is equipped with a chamber cover.

[0016] As a preferred technical solution, the counter adjustment knob on the control panel is connected to a high-speed counter to set the threshold number of cigarette packs required for the refueling interval.

[0017] On the other hand, a refueling method is proposed for use in the dual-channel dry-wet separation refueling device for the inner lining paper of small cigarette packs as described above. The refueling method includes a manual refueling method and an automatic refueling method; wherein, the automatic refueling method includes:

[0018] Step 1: The small cigarette pack packaging machine is powered on and automatically identifies whether the inner lining paper being used is on the left or right side. If it is determined that the inner lining paper is on the left side, then this refueling will be done by refueling the left refueling point through the left refueling pipeline.

[0019] Step 2: The cigarette pack counting sensor on the small cigarette pack conveying channel detects the passage of the small cigarette pack and sends the signal to the high-speed counter for counting. The high-speed counter is an additive counter. When the high-speed counter reaches the set value, the high-speed counter outputs a signal to the electronic time relay.

[0020] Step 3: The electronic time relay outputs a time pulse signal, which passes through the first solid-state relay to the first air valve. The first air valve is opened, and clean compressed air enters the oil mist lubricator, which contains liquid paraffin.

[0021] Step 4: Liquid paraffin reaches the left filling valve, and another path reaches the electronic time relay of the left filling pipeline. The electronic time relay of the left filling pipeline outputs a time pulse signal. The time pulse signal passes through the second solid-state relay to the left filling valve, the left filling valve is turned on, the left pipeline switch valve is opened, and the liquid paraffin reaches the left felt.

[0022] Step 5: After refueling is complete, the high-speed counter is reset.

[0023] As a preferred technical solution, when refueling using the manual refueling method, the left or right channel can be selected by using the side selection knob, and the corresponding side refueling valve can be directly driven by pressing the manual refueling button.

[0024] As a preferred technical solution, when refueling using the manual refueling method, if manual venting is required, the following steps are taken: closing the pipeline switch valve, manually opening the vent valve, and triggering the manual refueling button until all gas is vented.

[0025] Compared with the prior art, the present invention achieves the following technical advantages: the refueling device of the present invention realizes complete separation of dry and wet refueling, independent refueling through dual channels, and has manual refueling and manual venting functions. The refueling interval of the new refueling device is set by adjusting the counter on the tank panel, and the refueling time is set by adjusting the electronic time relay, making parameter adjustment convenient and quick.

[0026] Other features and advantages of this application will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing this application. Attached Figure Description

This oiling device includes:

[0042] The refueling module and the refueling electrical control module are used to control the refueling action. The refueling electrical control module can use a programmable logic controller (PLC) as the control unit, offering good stability and high reliability; alternatively, it can use a combination of a counter and an electronic time relay as the control unit, allowing for easy adjustment of refueling quantity and refueling time interval parameters, and eliminating the problem of parameter loss when the battery is low.

[0043] The compartment 1 comprises a dry chamber 11 and a wet chamber 12. The dry chamber 11 houses the refueling electrical control module, while the wet chamber 12 houses the refueling module. The refueling module includes a refueling dispenser with left and right refueling lines connected to its sides. The left refueling line connects to a left-side refueling point, and the right refueling line connects to a right-side refueling point. The left and right refueling lines are equipped with an exhaust valve 50, a refueling valve, and a line switch valve 70, respectively. The refueling dispenser includes an oil mist lubricator 40, which is connected to a first air valve 30 and an external air compressor. The first air valve 30 controls the entry of compressed air into the oil mist lubricator 40, which contains liquid paraffin. The refueling module is housed within the wet chamber 12, isolating the dry chamber 11 from the wet chamber 12 to prevent liquid paraffin from splashing and contaminating electronic components during refueling.

[0044] It also includes an operation panel, which is located on the outer wall of the partitioned housing 1, and integrates a high-speed counter adjustment knob, a time relay adjustment knob, a manual refueling button, and a side selection knob.

[0045] Preferably, liquid paraffin is provided in the oil mist lubricator 40, and the oil filling valve is used to control the opening or closing of the oil filling point. The liquid paraffin is then controlled to be output to the felt.

[0046] Preferably, the exhaust valve 50 is located on the pipeline between the refueling valve and the pipeline switch valve 70.

[0047] Preferably, two independent valve groups are installed side by side in the wet chamber 12. Each valve group includes an exhaust valve 50, a refueling valve (including a left refueling valve 60 and a right refueling valve 80), and a pipeline switch valve 70.

[0048] Preferably, when a programmable logic controller (PLC) is used as the control unit, the parameters are stored in the non-volatile memory of the PLC; when a combination of a high-speed counter and an electronic time relay is used as the control unit, the parameters are set by a mechanical knob and do not require battery storage.

[0049] Preferably, the volume of the dry chamber 11 is larger than the volume of the wet chamber 12, and the partitioned box 1 is equipped with a box cover 2.

[0050] Preferably, the counter adjustment knob on the control panel is connected to a high-speed counter to set the threshold number of cigarette packs required for the refueling interval.

[0051] Example 2

[0052] like Figure 2 As shown, this embodiment presents a refueling method for use in the dual-channel dry-wet separation refueling device for the inner lining paper of small cigarette packs, as described in Embodiment 1. The refueling method includes a manual refueling method and an automatic refueling method. The automatic refueling method includes:

[0053] Step 1: The small cigarette pack packaging machine is powered on and automatically identifies whether the inner lining paper being used is on the left or right side. If it is determined that the inner lining paper is on the left side, then this refueling will be done by refueling the left refueling point through the left refueling pipeline.

[0054] Step 2: The cigarette pack counting sensor on the small cigarette pack conveying channel detects the passage of the small cigarette pack and sends the signal to the high-speed counter for counting. The high-speed counter is an additive counter. When the high-speed counter reaches the set value, the high-speed counter outputs a signal to the electronic time relay.

[0055] Step 3: The electronic time relay outputs a time pulse signal, which passes through the first solid-state relay to the first air valve 30. The first air valve 30 is turned on, and clean compressed air enters the oil mist lubricator 40, which contains liquid paraffin.

[0056] Step 4: Liquid paraffin reaches the left filling valve 60, and another path leads to the electronic time relay of the left filling pipeline. The electronic time relay of the left filling pipeline outputs a time pulse signal. The time pulse signal passes through the second solid-state relay to the left filling valve 60, and the left filling valve 60 is turned on, opening the left pipeline switch valve 70, and the liquid paraffin reaches the left felt.

[0057] Step 5: After refueling is complete, the high-speed counter is reset.

[0058] The above implementation method only shows the method of refueling the left refueling point. Similarly, if the refueling paper is identified as being on the right, the method is the same.

[0059] Preferably, when using the manual refueling method, the left or right channel can be selected by using the side selection knob on the control panel, and the manual refueling button can be pressed to directly drive the refueling valve on the corresponding side.

[0060] Preferably, when using the manual refueling method, if manual venting is required, the method includes: closing the pipeline switch valve 70, manually opening the vent valve 50, and triggering the manual refueling button until all gas is released. After venting is complete, it is necessary to manually return to automatic refueling mode. All of the above operations can be performed and switched via the control panel.

[0061] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
