Description

Technical Field

[0001] This disclosure relates to the field of tobacco manufacturing technology, and in particular to a liquid supply device and liquid supply system. Background Technology

[0002] Liquid supply systems are generally used to store and supply various liquids (such as water, adhesives, oils, etc.), including liquid supply devices for real-time liquid storage, and may also include additional liquid storage devices to replenish the liquid in the tank.

[0003] In the tobacco manufacturing industry, a liquid supply device is used to supply adhesive to the glue gun, enabling it to continuously apply adhesive lines along the cigarette paper overlap. For example... Figure 1 As shown, the related liquid supply device includes a housing 1', a moving device 2', a filtering device 3', and a liquid supply channel 4'. The housing 1' is a cylindrical housing containing adhesive liquid. By applying compressed air into the housing 1', the adhesive liquid is forced out of the housing 1'. One end of the liquid supply channel 4' is connected to the adhesive outlet of the housing 1'. After being forced out of the housing 1', the adhesive liquid flows through the liquid supply channel 4' into the filtering device 3' for filtration, and finally flows to the glue gun via a liquid pump. The moving platform of the moving device 2' is configured to place the housing 1' and drive the housing 1' to reciprocate along a first direction A' for easy maintenance.

[0004] However, during the liquid supply process, the moisture in the adhesive gradually evaporates upon contact with compressed air, causing the solid components in the adhesive to become fixed on the inner wall of the housing 1'. Furthermore, the polymers in the adhesive react with the chemicals in the compressed air, contaminating the adhesive and forming a dense adhesive film inside the housing 1'. This can lead to poor adhesive dispensing from the outlet and blockage of the filter, reducing the liquid supply efficiency of the device and even causing malfunctions such as cigarette clip breakage and cigarette pack slippage, thus lowering production quality. To mitigate these issues, the liquid supply device needs frequent cleaning, increasing maintenance time and workload, and further reducing production efficiency. Utility Model Content

[0071] like Figure 2As shown, this embodiment of the present disclosure provides a liquid supply device. The liquid supply device includes: a housing 100, a liquid storage bag 200, and a liquid supply channel 800. The housing 100 includes a receiving space 100A and a first connection port. The liquid storage bag 200 is located within the receiving space 100A and is configured to store liquid. The liquid storage bag 200 includes a liquid outlet 200a. The first end of the liquid supply channel 800 is located outside the liquid storage bag 200 and enters the receiving space 100A through the first connection port, communicating with the liquid outlet 200a. The second end of the liquid supply channel 800 is configured to supply liquid to the outside of the housing 100.

[0072] Based on the liquid supply device provided in this disclosure, a liquid storage bag 200 is provided in the accommodating space 100A of the housing 100. The liquid storage bag 200 is configured to store liquid, and a liquid supply channel 800 is provided to communicate with the liquid outlet 200a of the liquid storage bag 200, thereby supplying liquid to the outside through the second end of the liquid supply channel 800. This liquid supply device helps to avoid contact between the liquid and the external environment, and helps to prevent the liquid from evaporating or being contaminated, thereby helping to improve production quality and production efficiency.

[0073] In some embodiments, the liquid is an adhesive. This liquid supply device helps to prevent the adhesive from coming into contact with air, thereby avoiding problems such as the adhesive evaporating and solidifying, and the adhesive reacting with chemicals in the air to form an adhesive film, which could cause blockages in the outlet 200a and the supply channel 800. It also helps to save time in cleaning the liquid supply device, thereby improving production efficiency.

[0074] In some embodiments, the liquid storage bag 200 can be a refillable liquid storage bag 200. Corresponding to the refillable liquid storage bag 200, a fixed liquid storage device can be provided for filling the liquid storage bag 200, or a flowing liquid storage device can be used to fill the liquid storage bag 200. The liquid storage bag 200 can also be a disposable liquid storage bag 200, that is, the liquid is replenished by replacing the liquid storage bag 200. This arrangement helps to save time and cost in cleaning the liquid storage bag 200, and also facilitates the replacement of the liquid storage bag 200 at any time when quality problems occur, thereby improving production efficiency.

[0075] like Figure 2 As shown, in some embodiments, the liquid supply device further includes a filter 300 and a liquid pump 400. The filter 300 is connected between a first end and a second end of the liquid supply channel 800 and is configured to filter the liquid. The liquid pump 400 is connected between the first end and the second end of the liquid supply channel 800 and is configured to provide power to allow the liquid to flow from the outlet 200a to the second end.

[0076] The filter device 300 facilitates the filtration of the liquid, thereby improving production quality. The liquid pump 400 facilitates the rapid flow of liquid from the outlet 200a to the second end, thereby improving production efficiency.

[0077] In some embodiments, the filtration device 300 includes a filter element with a volume ranging from 1L to 3L.

[0078] Compared with related technologies, the volume of the filter element in this application is increased several times, for example, up to about 33 times. This arrangement is beneficial for increasing the filtration area and improving the filter element's ability to handle contaminants, thereby increasing the filtration efficiency and service life of the filter device 300, and also reducing the frequency of filter element replacement and maintenance costs.

[0079] like Figure 2 and Figure 5 As shown, in some embodiments, the height of the filter inlet 301a of the filter device 300 is lower than the height of the filter outlet 301b of the filter device 300.

[0080] This setting allows the adhesive to come into more thorough contact with the filter element during the filtration process, thereby improving the filtration quality.

[0081] like Figure 2 As shown, in some embodiments, the height of the filter outlet 301b of the filter device 300 is lower than the height of the liquid outlet 200a. Along the flow direction of the liquid within the liquid supply channel 800, the liquid pump 400 is located downstream of the filter device 300. The liquid pump 400 is configured to provide power to cause the liquid to flow from the filter outlet 301b to the second end.

[0082] The height of the filter outlet 301b is lower than that of the liquid outlet 200a. Driven by its own gravity and pressure difference, the liquid can flow from the liquid outlet 200a to the filter outlet 301b. This allows the liquid pump 400 to provide the power to propel the liquid from the filter outlet 301b to the second end, which helps reduce energy consumption and extend the service life of the liquid pump 400. Due to gravity, the lower height of the filter outlet 301b compared to the liquid outlet 200a helps create a pressure difference. This pressure difference facilitates the rapid flow of liquid from the liquid outlet 200a to the filter device 300, thereby reducing reliance on the liquid pump 400, further reducing energy consumption, and extending the service life of the liquid pump 400.

[0083] like Figure 2 As shown, in some embodiments, the liquid supply device further includes a tank support 500. The top of the tank support 500 supports the tank 100.

[0084] The housing support 500 helps to provide stable support for the housing 100, thereby preventing the housing 100 from shaking and causing air and other impurities to be mixed into the liquid at the outlet 200a.

[0085] In some embodiments, the filter device 300 is detachably connected to the housing support 500. For example, the filter device 300 may be detachably connected to the housing support 500 via a threaded connection.

[0086] This setup facilitates quick assembly and disassembly of the filter unit 300 and the housing support 500, promotes a compact structure, and allows for flexible arrangement of the height of the filter unit 300.

[0087] In some embodiments, the liquid pump 400 is detachably connected to the housing support 500.

[0088] This setup facilitates quick assembly and disassembly of the pump 400 and the housing support 500, contributes to a compact structure, and allows for flexible arrangement of the pump 400's height.

[0089] In some embodiments, the height of the filter outlet 301b of the filter device 300 is lower than the height of the top of the housing support 500.

[0090] The housing support 500 raises the height of the housing 100, which makes the height of the liquid outlet 200a higher than the height of the filter inlet 301a and the filter outlet 301b, thereby facilitating the rapid flow of liquid from the liquid outlet 200a to the filter device 300.

[0091] In some embodiments, the liquid pump 400 is detachably connected to the housing support 500. The height of the filter outlet 301b of the filter device 300 is higher than the liquid pump inlet of the liquid pump 400.

[0092] This design helps reduce energy loss during the flow of liquid within the supply channel 800, thereby improving the supply efficiency.

[0093] In some embodiments, the liquid supply device further includes a moving device. The moving device includes a slide rail and a moving stage 601. The slide rail extends along a first direction A. The moving stage 601 includes a slide rail extending along the first direction A. The slide rail is configured to slide in engagement with the slide rail along the first direction A, so that the moving stage 601 reciprocates along the first direction A. A housing support 500 is placed on the moving stage 601.

[0094] The housing support 500 is placed on the moving platform 601, which facilitates the stable movement of the housing 100, the filter device 300, and the liquid pump 400 mounted on the housing support 500 along the first direction A, thereby facilitating the maintenance of the liquid supply device. Furthermore, compared to directly connecting the housing 100 to the moving platform 601, placing the housing 100 on the housing support 500 and placing the housing support 500 on the moving platform 601 increases the support area for the housing 100, thus helping to prevent the housing 100 from falling during movement due to insufficient support area on the slide rail.

[0095] In some embodiments, the liquid supply device further includes a detection device 900 and an alarm device. The detection device 900 is configured to detect the liquid level within the storage bag 200. The alarm device is signal-connected to the detection device 900 and configured to sound an alarm based on the detection result of the detection device 900. For example, when the detection device 900 detects that the liquid level has reached or fallen below a preset lower limit, it sends a signal to the alarm device, which then activates the alarm upon receiving the signal. The alarm device may be, for example, an alarm siren, an alarm light, etc.

[0096] This feature allows the detection device 900 to promptly alert staff when the liquid level in the storage bag 200 is low, enabling them to replace the storage bag 200 or replenish the liquid in a timely manner.

[0097] In some embodiments, the storage bag 200 includes a level plate. The level plate is located at the top of the storage bag 200. The detection device 900 is configured to detect the liquid level by detecting the height position of the level plate.

[0098] Setting up a liquid level plate helps improve the accuracy of the detection device 900 and also helps to visually indicate the extent of the liquid level drop, thus facilitating manual observation of the liquid level in the storage bag 200.

[0099] like Figure 2 As shown, in some embodiments, the box 100 is a cube.

[0100] Setting the enclosure 100 as a cube helps to increase the cross-sectional area of ​​the enclosure 100 in the horizontal direction, which in turn helps to shorten the height of the enclosure 100, saves installation space in the vertical direction, and also helps to improve the stability of the enclosure 100 on the enclosure support 500.

[0101] In other embodiments, the housing 100 may also be any suitable shape or structure other than a cube.

[0102] like Figure 2 As shown, in some embodiments, the housing 100 includes an opening at the top, through which the liquid storage bag 200 is inserted into the receiving space 100A. The liquid supply device may include a lid 110. The lid 110 is detachably connected to the housing 100 to open or close the opening. Figure 4 As shown, in some other embodiments, the cover 110 may include an observation hole 110a. The observation hole 110a allows for observation of the status of the liquid storage bag 200 inside the box 100 at any time, which is beneficial for timely checking of the liquid level and whether the liquid storage bag 200 is damaged or leaking, thereby facilitating timely replacement of the liquid storage bag 200 or replenishment of liquid into the liquid storage bag 200.

[0103] In some embodiments, the lid 110 further includes two handles located on both sides of the observation hole 110a along the length of the lid 110, thereby facilitating the operator to open or close the lid 110 at any time. Figure 4 As shown, in some embodiments, each handle (not shown) is threaded to the cover 110 via two threaded mounting holes 110b.

[0104] In some embodiments, the outlet 200a is located at the bottom of the storage bag 200.

[0105] This arrangement facilitates the flow of liquid from the outlet 200a to the filter device 300 by gravity, thereby preventing impurities such as air from entering the storage bag 200 through the outlet 200a and contaminating the liquid.

[0106] In some embodiments, the storage bag 200 further includes an inlet 200b for replenishing liquid.

[0107] This setup helps reduce the frequency of changing the reservoir bag 200, thereby reducing the cost of replenishing the fluid.

[0108] Another aspect of this disclosure provides a liquid supply system, which includes a liquid supply device and a liquid storage device provided in this disclosure. The liquid storage device is configured to store liquid for replenishing the liquid storage bag 200.

[0109] The liquid supply system of this disclosure has the advantages of the liquid supply device of this disclosure. In addition, the liquid supply system includes a liquid storage device, which facilitates timely replenishment of liquid into the storage bag 200, thereby improving the liquid supply efficiency of the liquid supply device.

[0110] In some embodiments, the liquid storage device can be configured to be continuously connected to the liquid supply device to continuously supply the required liquid to the liquid supply device. In other embodiments, the liquid storage device can also be detachably connected to the liquid supply device, so that when the liquid level in the storage bag 200 is high, the liquid supply device can operate independently, which improves the flexibility of the liquid supply device. When the liquid level in the storage bag 200 is low, the liquid storage device can quickly replenish the liquid, more timely meeting the liquid demand of the liquid supply device and improving the liquid supply efficiency of the liquid supply system.

[0111] like Figure 6As shown, in some embodiments, the liquid supply system further includes an inlet connector 2. The inlet connector 2 is configured to connect the liquid storage device and the liquid storage bag 200, and includes a connector body 21 and a sealing cap 22. The connector body 21 includes an exhaust port 2a, a first interface 2b, a second interface 2c, and a connector cavity 2A connecting the exhaust port 2a, the first interface 2b, and the second interface 2c. The first interface 2b is configured to communicate with the liquid storage bag 200, and the second interface 2c is configured to communicate with the liquid storage device. The sealing cap 22 is detachably connected to the connector body 21 and is configured to seal the exhaust port 2a.

[0112] On the one hand, the first interface 2b, the second interface 2c of the inlet connector 2, and the connector cavity 2A connecting the first interface 2b and the second interface 2c facilitate the connection between the liquid storage bag 200 and the liquid storage device, which helps prevent leakage and also facilitates the detachable and quick connection between the liquid storage device and the liquid supply device. On the other hand, the liquid supply device facilitates the discharge of gas from the liquid storage bag 200 through the vent 2a of the inlet connector 2, thereby reducing liquid evaporation and contamination.

[0113] like Figure 6 As shown, in some embodiments, the inlet connector 2 further includes a pressure cap 23 disposed at the first interface 2b and covering the first interface 2b. The pressure cap 23 is configured to press against the liquid storage bag 200 while the first interface 2b is connected to the liquid storage bag 200.

[0114] The pressure cap 23 helps to restrict the connection position between the liquid inlet connector 2 and the liquid storage bag 200, thereby helping to prevent leakage and also helping to prevent impurities such as gas from entering the liquid storage bag 200 through the gap at the connection position between the first interface 2b and the liquid storage bag 200.

[0115] like Figure 7 As shown, in some embodiments, the liquid storage device includes a pneumatic pump and a pressure regulating valve 14. The pneumatic pump is configured to provide power to flow liquid from the liquid storage device to the liquid storage bag 200. The pressure regulating valve 14 is connected to the air supply line 17 of the pneumatic pump and is configured to regulate the air pressure in the air supply line 17.

[0116] The pneumatic pump facilitates the rapid and smooth flow of liquid from the accumulator to the storage bag 200, thereby improving the liquid supply efficiency of the supply system. The pressure regulating valve 14 helps regulate the air pressure generated by the pneumatic pump, thus controlling the air pressure to prevent excessive pressure from causing liquid to overflow from the connection point, or insufficient pressure from preventing liquid from flowing from the accumulator to the supply device. Controlling the opening and closing of the pressure regulating valve 14 also allows control over whether the accumulator begins or stops supplying liquid to the supply device.

[0117] In some embodiments, the pressure regulating valve 14 is coupled to the detection device 900 of the liquid supply device and is configured to adjust the air pressure according to the detection result of the detection device 900.

[0118] This setting allows for precise control of the air pressure based on the liquid level within the storage bag 200. For example, when the detection device 900 detects that the liquid level is higher than a preset lower limit, the pressure regulating valve 14 adjusts the air pressure to zero, thus preventing liquid from being supplied to the liquid supply device. Alternatively, when the detection device 900 detects that the liquid level is lower than a preset lower limit, the pressure regulating valve 14 increases the air pressure, thereby supplying liquid to the liquid supply device, facilitating timely replenishment of the storage bag 200.

[0119] In some embodiments, the liquid supply system further includes a control device. The pressure regulating valve 14 and the detection device 900 can be signal-connected via the control device.

[0120] The control device automatically receives signals and controls the pressure regulating valve 14 to adjust the air pressure, which helps improve the level of automation. By connecting with the detection device 900, the control device can quickly respond to the detection results of the detection device 900. This allows for rapid and accurate control of the pressure regulating valve 14 to adjust the air pressure when the liquid level in the storage bag 200 reaches or falls below the preset lower limit, thereby replenishing the liquid in the storage bag 200 and ensuring the stability and reliability of production.

[0121] The control device may be implemented as a general-purpose processor, a programmable logic controller (PLC), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic device, discrete gate or transistor logic device, discrete hardware component, or any suitable combination thereof for performing the functions described in this disclosure.

[0122] The following combination Figures 2 to 7 The liquid supply device and liquid supply system according to the embodiments of this disclosure will be described in detail.

[0123] like Figure 2As shown, the liquid supply device includes a housing 100, a lid 110, a storage bag 200, a supply channel 800, a filter 300, a pump 400, a housing support 500, a moving device, a detection device 900, a control device, and an alarm device. The housing 100 includes a containing space 100A, a first connection port, and an opening at the top of the housing 100. The lid 110 is detachably connected to the housing 100 and is configured to close the opening of the housing 100 when connected to it. The storage bag 200 is placed within the containing space 100A and is configured to store liquid. The liquid is a gel. The storage bag 200 is a vacuum bag, including a liquid outlet 200a located at the bottom of the storage bag 200. The first end of the supply channel 800 is located outside the storage bag 200 and enters the containing space 100A through the first connection port, communicating with the liquid outlet 200a. The second end of the liquid supply channel 800 is configured to supply liquid to the outside of the housing 100. A filter device 300 is connected between the first and second ends of the liquid supply channel 800 and is configured to filter the adhesive liquid. A pump 400 is connected between the filter outlet 301b of the filter device 300 and the second end of the liquid supply channel 800 and is configured to provide power for the adhesive liquid to flow from the filter outlet 301b to the second end. The housing 100 is placed on top of the housing support 500. The filter device 300 is fixedly connected to the housing support 500 and is lower than the housing 100. The pump 400 is fixedly mounted on the housing support 500 and is lower than the filter device 300, thereby facilitating the rapid flow of the adhesive liquid from the outlet 200a to the second end by its own weight and the drive of the pump 400. The housing support 500 is supported on a moving platform 601 of a moving device. The moving platform 601 drives the housing support 500 to reciprocate along a first direction A, thereby facilitating maintenance of the liquid supply device. The detection device 900 is located above the cover 110 and is configured to detect the liquid level of the adhesive in the storage bag 200. The control device is connected to both the alarm device and the detection device 900 and is configured to control the alarm device to sound an alarm based on the detection result of the detection device 900.

[0124] This liquid supply device, by incorporating a storage bag 200 and an outlet 200a located at the bottom of the storage bag 200, facilitates the flow of the adhesive from the outlet 200a by its own weight. This helps prevent the adhesive from evaporating or becoming contaminated due to contact with compressed air or other impurities. It also prevents blockages in the outlet 200a, supply channel 800, filter device 300, and pump 400 caused by adhesive solidification or the formation of a dense film. This reduces the need for cleaning and maintenance, improving production quality and efficiency. The device includes a detection device 900 and an alarm device for real-time monitoring of the adhesive level in the storage bag 200, allowing for timely replenishment and further enhancing production efficiency.

[0125] like Figure 2 As shown, the housing 100 is configured as a cubic structure, which facilitates the stable placement of the housing 100 on top of the housing support 500.

[0126] The first connection port of the housing 100 is located at the bottom of the housing 100, which is convenient to be close to the outlet 200a located at the bottom of the liquid storage bag 200, which is beneficial to reduce the length of the liquid supply channel 800 within the accommodating space 100A, and facilitates the first end of the liquid supply channel 800 to pass through the first connection port and connect with the outlet 200a.

[0127] The bottom surface of the lid 110 has the same shape and structure as the top surface of the box 100, which is conducive to sealing the accommodating space 100A of the box 100.

[0128] like Figure 5 As shown, the filter device 300 includes a housing 301, a mounting protrusion 302, a filter inlet 301a, and a filter outlet 301b. The filter device 300 is mounted vertically on a housing support 500. The mounting protrusion 302 of the filter device 300 has a threaded hole that engages with a screw on the housing support 500, allowing the filter device 300 to be detachably connected to the housing support 500. The height of the filter inlet 301a is lower than the height of the filter outlet 301b. This design allows the adhesive to enter from the bottom of the filter element and flow out from the top, facilitating thorough contact between the adhesive and the filter element. It also promotes the natural settling of impurities in the adhesive due to gravity, thereby improving filtration quality and efficiency.

[0129] The liquid pump 400 is configured as a gear pump, including gears. When the gears inside the liquid pump 400 rotate, the space volume on the disengaged side of the gears increases and a vacuum environment is formed, thereby drawing the adhesive from the filter device 300 into the liquid pump 400. At the same time, the space volume on the meshing side of the gears decreases, transporting the adhesive in the liquid pump 400 from the liquid pump 400 to the second end of the liquid supply channel 800, thereby supplying the adhesive to the outside through the second end of the liquid supply channel 800.

[0130] The liquid pump 400 is located downstream of the filter device 300 along the flow direction of the adhesive in the liquid supply channel 800. Therefore, it is beneficial to reduce the impact of impurities in the adhesive on the liquid pump 400, extend the service life of the liquid pump 400, and enhance the working reliability of the liquid pump 400.

[0131] like Figure 2As shown, the housing 100 is placed on top of the housing support 500. The filter device 300 is suspended from the housing support 500 at a position below the top of the housing 100. The liquid pump 400 is fixedly installed on the housing support 500 at a position below the filter device 300. The housing support 500 facilitates the staggered arrangement of the housing 100, filter device 300, and liquid pump 400 along the height direction. This arrangement is simple and reliable, and facilitates the flow of the adhesive from the outlet 200a along the supply channel 800 to the filter inlet 301a and filter outlet 301b of the filter device 300 by its own weight.

[0132] like Figure 2 As shown, the moving device includes a slide rail and a moving platform 601. The slide rail extends along a first direction A. The moving platform 601 includes a slide rail extending along the first direction A. The slide rail is configured to slide in conjunction with the slide rail along the first direction A, so that the moving platform 601 reciprocates along the first direction A. The housing support 500 includes a square platform and four legs. The four legs support the four bottom corners of the platform respectively. The four legs are supported on the moving platform 601. The housing support 500 helps to prevent the housing 100 from directly contacting the slide rail, which helps to increase installation stability and prevents the housing 100 from falling off during reciprocating movement along the first direction A.

[0133] The storage bag 200 includes a level plate at its top. As the level of the adhesive in the storage bag rises and falls, the level plate changes height accordingly. A detection device 900 detects the level plate's position. When the level plate drops to its lower limit, the detection device 900 sends a signal to the control device. The control device receives the signal and activates an alarm to alert the operator to add adhesive promptly. This prevents the adhesive from running out and causing supply failures, reduces the need for the supply device to stop for replenishment, and avoids insufficient supply leading to cigarette popping. Ultimately, this improves production quality and efficiency.

[0134] The liquid supply system of this embodiment includes a liquid supply device, a liquid storage device, and a liquid inlet connector 2. The liquid storage device is configured to store adhesive liquid for replenishing the liquid storage bag 200. The liquid inlet connector 2 is configured to connect the liquid storage device and the liquid storage bag 200. The liquid supply system including the liquid storage device facilitates timely replenishment of adhesive liquid into the liquid storage bag 200, thereby improving the liquid supply efficiency of the liquid supply device. The liquid inlet connector 2 helps prevent leakage at the connection between the liquid supply device and the liquid storage device, and also facilitates quick connection between the liquid storage device and the liquid supply device.

[0135] In this embodiment, the liquid storage device is a mobile glue cart, which facilitates rapid replenishment of the liquid supply device. The glue cart has containers for different types of glue, thus enabling the liquid supply system to be adapted to the production of cigarettes of different specifications. Figure 2The middle arrow indicates the flow path of the adhesive from the liquid storage device to the liquid storage bag 200.

[0136] like Figure 6 As shown, the inlet connector 2 includes a connector body 21, a sealing cap 22, a pressure cap 23, and a connector 24. The connector body 21 is a three-way pipe, including an exhaust port 2a, a first interface 2b, a second interface 2c, and a connector cavity 2A connecting the exhaust port 2a, the first interface 2b, and the second interface 2c, wherein the exhaust port 2a and the first interface 2b are arranged opposite to each other. The first interface 2b is configured to communicate with the liquid storage bag 200, and the second interface 2c is configured to communicate with the liquid storage device. The inlet connector 2 facilitates a quick connection between the liquid storage device and the liquid storage bag 200.

[0137] The sealing cap 22 is threadedly connected to the connector body 21 and is configured to seal the vent 2a. When gas is detected in the liquid storage bag 200, the gas is discharged from the vent 2a by unscrewing the sealing cap 22 and squeezing the liquid storage bag 200. This arrangement facilitates the rapid discharge of gas from the liquid storage bag 200, thereby helping to ensure the quality of the adhesive.

[0138] like Figure 6 As shown, connector 24 includes a through hole 24a. Through hole 24a includes a first threaded section. Liquid storage bag 200 includes a liquid storage bag body, a rigid pressure plate, and an inlet tube. The rigid pressure plate is embedded in the liquid storage bag body. The inlet tube extends from the rigid pressure plate in a direction away from the liquid storage bag body. The port at the end of the inlet tube away from the rigid pressure plate is configured as an inlet port 200b. The inlet tube includes a second threaded section located on the outer wall of the section of the inlet tube near the inlet port 200b and mates with the first threaded section of the through hole 24a of connector 24. Through the threaded engagement of the first and second threaded sections, the inlet tube of liquid storage bag 200 is detachably connected to the through hole 24a of connector 24, thereby detachably connecting to inlet tube connector 2. The section of connector body 21 including a first interface 2b is installed in the end of through hole 24a away from the first threaded section. With the inlet pipe connected to the inlet pipe connector 2, the inlet port 200b and the first interface 2b are positioned opposite each other along the extension direction of the pipe section including the first interface 2b of the connector body 21.

[0139] like Figure 6 As shown, connector 24 includes an annular groove on its outer wall. Gland 23 includes an annular mounting wall 231. The mounting wall 231 is mounted within the groove. Gland 23 is rotatably connected to connector 24 via the mounting wall 231 and covers the first interface 2b and the first threaded section. Gland 23 is configured to restrict the connection position of the inlet pipe to the inlet pipe connector 2, thereby preventing excessive extension of the inlet pipe within the connector cavity 2A.

[0140] By rotating the connector 24, the connector 24 moves closer to the liquid storage bag 200 in a direction perpendicular to the first interface 2b. During this process, the connector 24 is threadedly connected to the inlet pipe through the first threaded section and the second threaded section. The connector 24 applies pressure to the cap 23 through the mounting wall 231 so that the cap 23 is squeezed between the connector 24 and the rigid pressure plate of the liquid storage bag 200. This arrangement helps to limit the connection position of the threaded connection between the first threaded section and the second threaded section.

[0141] like Figure 2 As shown, the housing 100 also includes a second connection port 100b provided on the side wall, the moving platform 601 includes a quick connector 602, the liquid outlet pipe of the liquid storage bag 200 passes through the second connection port 100b and is connected to the liquid inlet pipe connector 2, and the second interface 2c of the liquid inlet pipe connector 2 is connected to the quick connector 602, thereby enabling quick connection between the liquid supply device and the liquid storage device.

[0142] like Figure 7 As shown, the liquid storage device includes a meter 13, a pressure regulating valve 14, a liquid storage tank 15, a pneumatic pump (not shown), and a quick-connect air connector 16. The pneumatic pump is located inside the liquid storage tank 15. The pneumatic pump includes a pneumatic pump air connector, which is configured to be detachably connected to the quick-connect air connector 16. The pressure regulating valve 14 is connected to the quick-connect air connector 16 and is configured to regulate the gas pressure in the air supply pipe 17 of the pneumatic pump by adjusting the air pressure output by the quick-connect air connector 16, thereby regulating the amount of power provided by the pneumatic pump to make the liquid flow from the liquid storage device to the liquid storage bag 200. The pressure regulating valve 14 is signal-connected to a control device. When the control device receives a detection signal from the detection device 900, it controls the pressure regulating valve 14 to open and adjust the pressure to 0.5 bar, thereby providing power to the pneumatic pump through the quick-connect air connector 16. Finally, the pneumatic pump delivers the adhesive liquid in the liquid storage tank 15 to the connector cavity 2A of the liquid inlet connector 2. The meter 13 is configured to detect the pressure of the gas output from the pressure regulating valve 14.

[0143] like Figure 2 As shown, the mobile station 601 includes a quick-connect air interface 603, through which gas-generated power is provided. A quick-connect air connector 16 is configured to be detachably connected to the quick-connect air interface 603 via an air supply conduit 17 to obtain power.

[0144] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and not to limit them; although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this disclosure or equivalent substitutions can be made to some technical features, all of which should be covered within the scope of the technical solutions claimed in this disclosure.
