Description

Technical Field

[0001] This application relates to the field of tobacco equipment technology, and in particular to rubber storage devices. Background Technology

[0002] In the cigarette production process, the adhesive used for the joint of the cigarette machine is crucial, and its stable and efficient operation directly affects the production quality and efficiency of cigarettes.

[0003] In related technologies, most cigarette rolling machines require a glue supply system for supplying and storing the adhesive used for the joint. A typical glue supply system consists of a glue tank, glue drawer, valve, glue filter, glue pump, and glue hose. The glue tank is placed on the glue drawer at the back of the cigarette rolling machine. The glue tank is used to store and transfer the joint adhesive; when the joint adhesive is needed, the glue pump transfers the adhesive from the tank to the required area.

[0004] However, in the existing technology, when it is necessary to add the joint adhesive to the glue bucket, the lid of the glue bucket needs to be opened to inject the adhesive. The adhesive is easily exposed to air, which aggravates the evaporation of the adhesive moisture and easily forms rubber skin and lumps. This can cause blockage of the glue supply device during operation, affect the bonding effect of the joint of the cigarette machine, and result in poor storage effect of the joint adhesive. Utility Model Content

[0020] The glue storage device also includes a seal; the seal is located on the side of the glue supply box away from the direction of gravity, and the seal is connected to the glue supply box to seal the glue supply box.

[0021] In some embodiments, an isolation valve is provided between the air inlet of the drive pump and the air supply source. The isolation valve is used to control the connection or disconnection of gas between the air inlet of the drive pump and the air outlet of the air supply source.

[0022] In some embodiments, the adhesive storage device further includes:

[0023] The controller, electrically connected to the isolation valve, is used to control the opening or closing of the isolation valve.

[0024] In some embodiments, the isolation valve is configured as a three-way valve; and / or

[0025] The isolation valve is configured as a solenoid valve.

[0026] In some embodiments, the adhesive storage device further includes:

[0027] The level gauge is connected to the glue supply tank and electrically connected to the controller. It is used to determine the liquid level of the glue in the glue supply tank and input the liquid level signal to the controller.

[0028] An alarm is connected to the glue supply tank and electrically connected to the controller. The controller receives the liquid level signal and determines whether the liquid level in the glue supply tank has reached the preset liquid level based on the liquid level signal.

[0029] When the glue level in the glue supply tank reaches the preset level, the controller activates the alarm.

[0030] In some embodiments, the adhesive storage device further includes:

[0031] A filter element is installed between the glue supply tank and the glue storage tank; the inlet of the glue storage tank and the outlet of the glue supply tank are connected through the filter element.

[0032] The aforementioned adhesive storage device includes an adhesive supply tank, an adhesive storage tank, and a drive pump.

The inlet of the adhesive storage tank is connected to the outlet of the adhesive supply tank. When the adhesive in the storage tank is low and it is necessary to add adhesive, it is only necessary to ensure the connection of adhesive between the adhesive supply tank and the adhesive storage tank. The adhesive in the adhesive supply tank can be transferred to the adhesive storage tank by gravity. Thus, during the transfer of adhesive, the adhesive will not come into contact with external gas, thereby extending the storage time of the adhesive without solidification and improving the storage effect of the adhesive.

[0034] In addition, since the air inlet of the drive pump is connected to the air supply source and the liquid inlet of the drive pump is connected to the liquid outlet of the glue storage tank, and the liquid outlet of the drive pump is used to discharge the glue, when the pressure of the gas inside the drive pump changes, the glue in the storage tank can be driven to be discharged through the liquid outlet of the drive pump. On the one hand, this can improve the stability of glue supply; on the other hand, during the process of transferring the glue, the glue will only flow in the liquid channel of the drive pump and will not come into contact with the gas in the gas channel of the drive pump, thereby further extending the storage time of the glue without solidification and further improving the storage effect of the glue.

[0041] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0042] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0043] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0044] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0046] It should be noted that the adhesive used in the cigarette making machine is crucial in the cigarette production process, and its stable and efficient operation directly affects the production quality and efficiency of cigarettes.

[0047] In related technologies, most cigarette rolling machines require a glue supply system for supplying and storing the adhesive used for the joint. A typical glue supply system consists of a glue tank, glue drawer, valve, glue filter, glue pump, and glue hose. The glue tank is placed on the glue drawer at the back of the cigarette rolling machine. The glue tank is used to store and transfer the joint adhesive. When the joint adhesive is needed, the glue pump transfers the adhesive from the tank to the desired location.

[0048] However, existing technology uses manual glue application. When it is necessary to add adhesive to the glue tank, the lid of the glue tank needs to be opened to inject the glue. The glue is easily exposed to air, which aggravates the evaporation of the glue moisture and easily forms glue skin and glue lumps. This can cause blockage of the glue supply device during operation, affect the bonding effect of the cigarette machine's joint, and cause serious quality problems such as air leakage and cigarette tipping.

[0049] Furthermore, the solidification of adhesive inside the glue drum is a common and significant problem. Generally, cigarette factories need to clean the glue drums during monthly maintenance, and such long-term storage leads to a large amount of solidified adhesive, resulting in substantial waste and reduced quality of the cigarette joints. At the same time, the significant amount of solidified adhesive makes cleaning difficult, requiring a combination of tools to achieve effective cleaning of the glue drum.

[0050] In summary, the existing methods for supplying and storing adhesives for cigarette making machines have several drawbacks in practical applications, including easy solidification and deterioration of the adhesive, poor storage performance of the adhesive, poor supply stability, and cumbersome manual operation. There is an urgent need for an adhesive storage device to solve these problems and improve the overall level and efficiency of cigarette production.

[0051] See Figure 1As shown. An embodiment of this application provides a glue storage device 1, including a glue supply tank 101, a glue storage tank 102, and a drive pump 103. The glue supply tank 101 is used to supply glue; the glue storage tank 102 is located on one side of the glue supply tank 101 in the direction of gravity; the liquid inlet of the glue storage tank 102 is connected to the liquid outlet of the glue supply tank 101; the drive pump 103 has an air inlet connected to an air supply source, a liquid inlet connected to the liquid outlet of the glue storage tank 102, and a liquid outlet for discharging glue.

[0052] It should be noted that, in this application, "overlap" refers to the area where the edges of cigarette paper overlap and adhere during the rolling process. Overlap adhesive refers to a functional adhesive specifically used in cigarette production to bond the overlap of cigarette paper (i.e., the overlapping area during cigarette paper rolling), and is a tobacco industry-specific auxiliary material. This overlap adhesive can also be called overlap glue, cigarette overlap glue, cigarette splicing glue, etc. Furthermore, the adhesive liquid in this application can be the aforementioned overlap adhesive, used to bond the overlap of cigarette paper. Of course, the adhesive liquid in this application can also be other types of adhesives and can be applied to other usage scenarios; therefore, the adhesive liquid in this application will not be limited or elaborated upon here.

[0053] Thus, by placing the glue storage tank 102 on one side of the glue supply tank 101 in the direction of gravity, and connecting the inlet of the glue storage tank 102 to the outlet of the glue supply tank 101, when the glue in the glue storage tank 102 is low and glue needs to be added, it is only necessary to ensure the connection of glue between the glue supply tank 101 and the glue storage tank 102. The glue in the glue supply tank 101 can be transferred to the glue storage tank 102 by gravity. Thus, during the transfer of glue, the glue will not come into contact with external gas, thereby extending the storage time of the glue without solidifying and improving the storage effect of the glue.

[0054] In addition, since the air inlet of the drive pump 103 is connected to the air supply source and the liquid inlet of the drive pump 103 is connected to the liquid outlet of the glue storage tank 102, the liquid outlet of the drive pump 103 is used to discharge the glue. Thus, when the pressure of the gas inside the drive pump 103 changes, the glue in the glue storage tank 102 can be driven to be discharged through the liquid outlet of the drive pump 103. On the one hand, this can improve the stability of glue supply; on the other hand, during the process of transferring the glue, the glue will only flow in the liquid channel of the drive pump 103 and will not come into contact with the gas in the gas channel of the drive pump 103. This can further extend the storage time of the glue without solidification and further improve the storage effect of the glue.

[0055] Specifically, the glue storage tank 102 is located on one side of the glue supply tank 101 in the direction of gravity (e.g., glue supply tank 101 is on top and glue storage tank 102 is below). The height difference creates a natural liquid level difference. The glue flows from the glue supply tank 101 into the glue storage tank 102 through the pipe. No opening of the lid or manual intervention is required throughout the process. This completely avoids the glue from contacting the air. As a result, the rate of water evaporation is reduced after the glue is isolated from the air. The curing and skinning phenomena caused by water loss are significantly reduced. This can extend the storage time of the glue without solidifying and improve the storage effect of the glue.

[0056] Based on the above description, the glue storage tank 102 is located on one side of the glue supply tank 101 in the direction of gravity, and glue replenishment can be completed by gravity alone. Compared with traditional pump transmission, it can reduce energy consumption. Furthermore, when the traditional pump or electrical control system fails, gravity transmission can still serve as a backup glue supply method to maintain basic production and ensure the normal operation of glue supply and storage.

[0057] Furthermore, since the air inlet of the drive pump 103 is connected to the air supply source, and the liquid inlet of the drive pump 103 is connected to the liquid outlet of the adhesive storage tank 102, the liquid outlet of the drive pump 103 is used to discharge the adhesive. It is understood that the drive pump 103 also includes an air outlet; the air inlet and outlet of the drive pump 103 form a gas channel, and the liquid inlet and outlet of the drive pump 103 form a liquid channel. That is, the gas channel and liquid channel of the drive pump 103 are isolated. Exemplarily, the air supply source only acts on the gas chamber of the drive pump 103, causing a change in the gas pressure within the gas chamber. The adhesive flows independently in the liquid chamber, without direct contact with the gas source (such as compressed air or nitrogen), thereby preventing oil, water, and impurities in the gas from mixing into the adhesive, and preventing volatile substances from the adhesive from contaminating the gas source system. This provides bidirectional protection, further extending the storage time of the adhesive without solidification and further improving the storage effect of the adhesive.

[0058] It is understandable that the glue storage device 1 of this application is simple to install and modify, low in cost, and easy to maintain. It can meet the practical needs of long-term glue storage and supply, effectively reduce glue solidification, and greatly reduce glue waste.

[0059] Optionally, the volume of the glue storage tank 102 is smaller than the volume of the glue supply tank 101. The glue storage tank 102 is used for temporary storage before use.

[0060] Thus, a hierarchical storage structure is formed by the volume difference design: "large-capacity glue supply tank 101 for storage + small-capacity glue storage tank 102 for temporary storage". The glue supply tank 101 is used to store batch glue, while the glue storage tank 102 only temporarily stores the amount of glue required for current production. This avoids the glue supply tank 101 being frequently opened, which would result in excessive contact area between the glue and air, reducing the risk of glue oxidation, moisture absorption, or contamination. This further extends the storage time of the glue without solidification and improves the storage effect of the glue.

[0061] In some embodiments, the adhesive storage device 1 further includes a heat sink 104 and a cooler 105. The heat sink 104 covers at least a portion of the outer surface of the adhesive supply tank 101; wherein, the outlet of the cooler 105 is connected to the inlet 1041 of the heat sink, and the outlet 1042 of the heat sink is connected to the inlet of the cooler 105.

[0062] In this way, the heat sink 104 and the refrigerator 105 form a circulating cooling system, which continuously absorbs the heat of the adhesive liquid in the glue supply tank 101 through the low temperature medium, and controls the temperature within a suitable process range. This can prevent the adhesive liquid from becoming abnormally viscous, deteriorating, or curing faster due to high temperature, and can ensure the stability of the adhesive strength and fluidity, and improve the storage effect of the adhesive liquid.

[0063] In addition, the heat sink 104 covers the outer surface of the glue supply box 101 and works in conjunction with the refrigerator 105 to build a stable heat exchange mechanism. This can effectively control the temperature fluctuation inside the glue storage device 1, reduce problems such as pipe aging and valve sealing failure caused by temperature stress, and extend the service life of the glue storage device 1.

[0064] Optionally, the chiller 105 uses electric cooling for water, with chilled water circulating through the heat sink 104 to maintain a low temperature inside the glue supply box 101. It is important to note that before starting the chiller 105, it is necessary to confirm that the power supply to the unit and control mechanism is connected, and that the cooling tower fan, cooling water pump, and chilled water pump are all turned on before proceeding with the startup.

[0065] Optionally, the temperature of the heat sink 104 can be set according to actual production needs. The temperature can be set to 10~25℃. At this temperature, the adhesive can be stored for a long time without solidifying.

[0066] Optionally, the heat sink 104 is made of stainless steel.

[0067] Based on the above description, in this embodiment, through the synergistic effect of heat dissipation component 104 and refrigerator 105, the adhesive storage device 1 can achieve the dual effect of continuous low temperature and sealed storage, which can isolate external air and moisture, greatly delay the solidification and deterioration of the adhesive, thereby further improving the storage effect of the adhesive.

[0068] In some embodiments, the liquid inlet 1041 of the heat sink is located on the side of the liquid outlet 1042 of the heat sink in the direction of gravity.

[0069] In this way, on the one hand, gravity can be used to drive the coolant to flow naturally, forming a stable "top-in, bottom-out" circulation path. This ensures that the low-temperature coolant fully contacts the surface of the glue supply tank 101, enhancing heat transfer efficiency and effectively controlling glue temperature fluctuations. On the other hand, gravity-assisted coolant flow reduces the risk of air blockage and bubble accumulation caused by pipe resistance or abnormal pump pressure, ensuring continuous and stable coolant circulation and improving the operational safety of the heat sink 104.

[0070] In some embodiments, the drive pump 103 is located on one side of the glue storage tank 102 in the direction of gravity.

[0071] In this way, gravity can be used to assist the flow of adhesive, reducing the suction resistance of the drive pump 103, lowering the energy loss of the adhesive in the pipeline, and ensuring that the adhesive can flow more smoothly from the storage tank 102 into the drive pump 103, thereby improving the efficiency and stability of the drive pump 103 in transferring adhesive. In addition, under the action of gravity, the adhesive can flow naturally into the drive pump 103, reducing the suction force that the pump body needs to overcome during startup and operation, which can reduce the energy consumption and mechanical wear of the drive pump 103 motor, extend the service life of the equipment, and reduce maintenance costs.

[0072] In some embodiments, the adhesive storage device 1 further includes a heat insulation element 106. The heat insulation element 106 covers at least a portion of the outer surface of the heat dissipation element 104.

[0073] In this way, the insulation component 106 can effectively block the heat exchange between the heat dissipation component 104 and the external environment, reduce the interference of ambient temperature fluctuations on the temperature control of the adhesive, and ensure that the temperature control system constructed by the refrigerator 105 and the heat dissipation component 104 accurately maintains the temperature of the adhesive within the process requirements range, avoiding changes in the performance of the adhesive caused by temperature loss or external heat intrusion, thereby further improving the storage effect of the adhesive.

[0074] In addition, the insulation component 106 provides protection for the heat dissipation component 104 and the internal coolant pipeline, which can prevent condensation, freezing or thermal expansion and contraction caused by environmental temperature differences, prevent pipeline rupture, aging of the seal 108 and other problems, extend the service life of the glue storage device 1, and reduce maintenance frequency and cost.

[0075] Optionally, the insulation component 106 may be made of polyurethane foam or polystyrene foam.

[0076] In some embodiments, the drive pump 103 is configured as one of a diaphragm pump, a magnetic pump, a shielded pump, and a bellows pump.

[0077] In this way, the drive pump 103 can avoid direct contact between the adhesive and the drive components through structures such as elastic diaphragms, magnetic coupling, shielding sleeves or bellows, effectively preventing wear and blockage of the drive pump 103 by high-viscosity adhesives or adhesives containing particles, and ensuring stable transmission of adhesives with different properties.

[0078] Specifically, by using structures such as diaphragms, magnetic couplers, shielding sleeves, or bellows, the channel for transmitting the adhesive can be completely separated from the air / mechanical component area of ​​the drive pump 103. This prevents air from seeping into the adhesive during mechanical movement and prevents the adhesive from coming into contact with air, thereby further extending the storage time of the adhesive without solidifying and further improving the storage effect of the adhesive.

[0079] Optionally, the drive pump 103 is configured as a pneumatic diaphragm pump. On one hand, the pneumatic diaphragm pump does not directly contact the adhesive, which is beneficial for the transportation, storage, and use of the adhesive. On the other hand, the pneumatic diaphragm pump has a metering function, which can quantitatively measure the amount of adhesive passing through the pump, making it convenient and practical.

[0080] In some embodiments, the glue storage device 1 further includes an air compressor 107; the air supply source is configured to be provided via the air compressor 107.

[0081] In this way, the compressed air in the air compressor 107 can directly act on the glue storage or transportation process, apply constant air pressure to the sealed glue storage tank 102 to overcome the flow resistance of high viscosity glue, and absorb the transportation pulse pressure through air pressure buffer at the end of the pipeline to make the glue output more stable. In conjunction with the vacuum pump, air pressure circulation is formed to accelerate the glue output process, which can improve glue supply efficiency and improve the stability and reliability of glue supply.

[0082] In some embodiments, see Figure 2 As shown, the glue storage device 1 also includes a sealing element 108; the sealing element 108 is located on the side of the glue supply box 101 away from the direction of gravity, and the sealing element 108 is connected to the glue supply box 101 to seal the glue supply box 101.

[0083] Thus, through the connection and cooperation between the sealant 108 and the glue supply box 101, a reliable sealing structure is formed in the direction away from gravity (such as the top and non-load-bearing surfaces of the box). This can prevent external air, dust, and other impurities from entering the glue supply box 101, avoiding oxidation, curing, or contamination of the glue upon contact with air, and maintaining the stability of the glue's performance. At the same time, it can prevent the glue from leaking from the non-load-bearing surfaces of the glue supply box 101 during storage or transportation, ensuring the cleanliness and safety of the glue supply box 101.

[0084] Optionally, the seal 108 is a sealing cap. When it is necessary to add adhesive, unscrew the sealing cap, add the adhesive, and tighten the sealing cap to maintain a seal.

[0085] In some embodiments, an isolation valve 109 is provided between the air inlet of the drive pump 103 and the air supply source. The isolation valve 109 is used to control the connection or disconnection of gas between the air inlet of the drive pump 103 and the air outlet of the air supply source.

[0086] Thus, by opening and closing the isolation valve 109, the gas connection between the air inlet of the drive pump 103 and the air outlet of the air supply source can be directly controlled. Specifically, when open, compressed air is smoothly input into the drive pump 103 (such as a pneumatic diaphragm pump) to drive the delivery of adhesive; when closed, the air supply is cut off to stop the pump, thereby realizing the start-stop control and working state switching of the adhesive storage device 1, meeting the operational needs of intermittent adhesive supply or emergency shutdown, and thus facilitating the operation of the operator.

[0087] In some embodiments, the adhesive storage device 1 further includes a controller 110. The controller 110 is electrically connected to the isolation valve 109 and is used to control the isolation valve 109 to open or close.

[0088] In this way, the opening and closing state of the isolation valve 109 can be precisely controlled by the electrical signal output of the controller 110. The connection or disconnection of the isolation valve 109 can be automatically controlled according to the preset program or real-time monitoring data, replacing manual operation to realize the unmanned operation of the glue storage device 1, meeting the automated glue supply needs in continuous production scenarios, and further facilitating the operation of operators.

[0089] In some embodiments, the isolation valve 109 is configured as a three-way valve.

[0090] Thus, multi-path control of the air supply to the drive pump 103 can be achieved through the three ports of the three-way valve. For example, the main path connects the air supply source to the air inlet of the drive pump 103 for normal glue supply, while the bypass port can be connected to a backup air source or the controller 110. When the main air source fails, the three-way valve switches to the bypass path to maintain glue supply. During shutdown, residual gas in the drive pump 103 is discharged into the atmosphere to prevent pressure buildup and component damage. Alternatively, the bypass port can be connected to the controller 110, which can then apply an open or closed signal to the isolation valve 109 to control the connection or disconnection between the air supply source and the air inlet of the drive pump 103.

[0091] In some embodiments, the isolation valve 109 is configured as a solenoid valve.

[0092] In this way, the electrical signal interface of the solenoid valve can be directly connected to automated control systems such as the controller 110 and industrial computers, enabling remote control without the need for mechanical linkages or pneumatic assistance. Operators can send switching commands via host computer software, and the solenoid valve synchronously executes the air circuit opening and closing actions, making it suitable for isolation switching requirements in unmanned workshops or hazardous environments. Simultaneously, the on / off state of the solenoid valve can be converted into an electrical signal and fed back to the control system, forming a closed-loop control of "command-execution-feedback," which can improve the system's automation level.

[0093] In some embodiments, the adhesive storage device 1 further includes a level gauge 111 and an alarm 112. The level gauge 111 is connected to the adhesive supply tank 101 and electrically connected to the controller 110, and is used to determine the liquid level of the adhesive in the adhesive supply tank 101 and input a liquid level signal to the controller 110; the alarm 112 is connected to the adhesive supply tank 101 and electrically connected to the controller 110; the controller 110 is used to receive the liquid level signal and determine whether the liquid level of the adhesive in the adhesive supply tank 101 has reached a preset liquid level; if the liquid level of the adhesive in the adhesive supply tank 101 reaches the preset liquid level, the controller 110 controls the alarm 112 to sound an alarm.

[0094] Thus, the level of adhesive in the glue supply tank 101 is continuously measured by the level gauge 111 (e.g., ultrasonic ranging, magnetic float level gauge 111), and the physical quantity of the liquid level is converted into an electrical signal and transmitted to the controller 110. Furthermore, the controller 110 analyzes the liquid level signal in real time and compares it with a preset threshold. When the liquid level is lower than the minimum threshold or higher than the maximum threshold, the alarm 112 is immediately triggered to issue an audible and visual alarm. This can prevent glue supply interruption due to insufficient adhesive or glue overflow caused by overfilling, thereby improving the safety of the production process.

[0095] In some embodiments, the glue storage device 1 further includes a filter element 113. The filter element 113 is disposed between the glue supply tank 101 and the glue storage tank 102; the liquid inlet of the glue storage tank 102 and the liquid outlet of the glue supply tank 101 are connected through the filter element 113.

[0096] Thus, the adhesive liquid is physically intercepted by the filter element 113 (such as a filter screen, filter element, or sintered metal filter). Specifically, when the adhesive liquid is output from the supply tank 101 to the storage tank 102, the filter element 113 can remove solid particles (such as adhesive liquid solidification clumps, metal fragments), fibrous impurities, or microbial coagulations in the adhesive liquid. This can prevent impurities from clogging the drive pump 103 or pipelines, and can maintain the purity of the adhesive liquid to ensure the accuracy of subsequent adhesive application processes.

[0097] Furthermore, the purification effect of filter element 113 on the adhesive can extend the service life of the adhesive. Specifically, it intercepts colloidal impurities generated by oxidation and polymerization reactions in the adhesive, preventing impurity deposition that could lead to abnormal viscosity or performance degradation of the adhesive. At the same time, stable adhesive cleanliness can reduce wear on components such as drive pump 103, extending the pump's operating life and reducing equipment maintenance costs caused by wear due to impurities.

[0098] Optionally, the filter membrane can be made of stainless steel or nylon. The filter membrane is a consumable and should be replaced every six months to one year, depending on the material and frequency of use. The pore size of the filter membrane can range from 40 mesh to 300 mesh, selected according to specific process requirements.

[0099] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0100] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
