Description

Technical Field

[0001] This utility model relates to the field of packaging bag manufacturing technology, and in particular to a glue spraying device and a cleaning device for a bag making machine. Background Technology

[0002] Adhesive spraying is a crucial step in the sealing process of packaging bags, and its quality directly affects the sealing strength and product reliability. Compared to other methods such as heat sealing and sewing, adhesive bonding has advantages such as strong adaptability, stable sealing effect, and minimal damage to the bag body. Therefore, more and more packaging bags are now being sealed using adhesive bonding.

[0003] In practical applications, it is usually necessary to pre-spray adhesive onto the areas of the bag that need to be sealed using a glue spraying mechanism, and then use a pressing sealing mechanism to press the bag joint to seal the bag. Throughout the adhesive sealing process, the amount of adhesive sprayed and the area sprayed significantly affect the stability of the bag seal. Some existing technologies use ball-bearing glue applicators for this purpose. Specifically, when the ball-bearing glue applicator contacts the bag, it rolls relative to the bag, dispensing adhesive onto the bag. However, even when the equipment is not in operation, adhesive may continue to overflow. This overflowing adhesive can contaminate the bag, and after prolonged inactivity, the overflowing adhesive can solidify on the applicator, preventing normal glue dispensing upon restarting, resulting in uneven glue application or even complete interruption of spraying. Ultimately, this leads to poor bag sealing or production interruption, affecting the sealing effect and even causing bag sealing failure. Currently, operators often rely on manual cleaning or replacement of the applicator to solve this problem, which is not only complex but also results in high maintenance costs.

[0004] Therefore, existing glue spraying devices have problems such as overflowing glue and contaminating the bag or failing to dispense glue due to blockage. Utility Model Content

[0005] The purpose of this invention is to solve the problems of glue spraying devices in the prior art, such as glue overflow contaminating the bag or glue not being dispensed due to blockage.

[0006] To achieve the above objectives, this application provides a cleaning device for the glue spraying mechanism of a bag making machine, comprising: a frame, a cleaning assembly, and a sealing cover; the cleaning assembly is mounted on the frame, and one end of the cleaning assembly has a filling port, and the other end has a cleaning liquid outlet communicating with the filling port; one end of the sealing cover is disposed around the cleaning liquid outlet at the other end of the cleaning assembly, and the other end of the sealing cover extends outward along the length direction of the cleaning assembly and forms a cleaning chamber inside; furthermore, the end face of the sealing cover away from the other end of the cleaning assembly is provided with a sealing joint portion adapted to engage with the outer peripheral wall of the glue spraying mechanism.

[0007] Using the above technical solution, the cleaning device provided in this application includes a frame, a cleaning component, and a sealing cover. The frame provides stable installation for the cleaning component and the sealing cover. The cleaning component injects cleaning fluid through the filling port and directs the cleaning fluid to the glue spraying mechanism through the cleaning fluid outlet to directly dissolve or flush away residual glue, preventing glue overflow from accumulating and blocking the glue outlet of the glue spraying mechanism, affecting normal secondary use, or contaminating the bag during secondary glue spraying. One end of the sealing cover forms a sealed connection around the cleaning fluid outlet, and the other end extends to form a cleaning chamber to accommodate the glue spraying mechanism for cleaning. The sealing joint at its end face is tightly fitted to the outer peripheral wall of the glue spraying mechanism, which can completely seal the chamber during the cleaning process of the glue spraying mechanism, thereby preventing glue or cleaning fluid from leaking out and contaminating the bag.

[0008] Therefore, the cleaning device provided in this application, when applied to the glue spraying mechanism of a bag making machine, can not only prevent the glue spraying device from overflowing and contaminating the bag or failing to spray glue due to blockage during use, ensuring that the bag is always sealed with an appropriate amount of glue and has good structural stability; it can also avoid the risk of contaminating the bag during the cleaning process, which is conducive to further improving the bag making stability of the bag making equipment, thereby improving the pass rate and aesthetics of the bag production.

[0009] According to the cleaning device for the glue spraying mechanism of the bag making machine provided in this application, the sealing joint is an annular elastic protrusion structure fixed to the end face of the other end of the sealing cover, and the sealing cover is a telescopic member that can deform along the length direction.

[0010] Using the above technical solution, the annular elastic protrusion structure is fixed to the end face of the sealing cover. Based on the shape change and contact pressure of the outer peripheral wall of the glue spraying mechanism, the annular elastic protrusion structure can adapt to deformation and always maintain a sealed contact, which can reduce the risk of cleaning fluid leakage at the joint. Moreover, the sealing cover adopts a telescopic component that can deform along the length direction, which can adapt to the position of the glue spraying mechanism, making it more adaptable. Even if there is a slight change in the position of the glue spraying mechanism, it can still fit and engage with the outer peripheral wall of the glue spraying mechanism. This allows the glue spraying mechanism to be cleaned in a closed environment in various applications, which can further reduce the risk of the cleaning fluid and glue mixture contaminating the bag during the cleaning process.

[0011] According to the cleaning device for the glue spraying mechanism of a bag making machine provided in this application, the sealing cover is configured as a corrugated cylindrical structure, and the annular elastic protrusion structure is configured as an annular elastic protrusion formed on the inner edge of the opening of the corrugated cylindrical structure.

[0012] By adopting the above technical solution, the sealing cover is set as a corrugated cylindrical structure. Since the corrugated structure has the advantages of high flexibility in its length direction and high support in its circumferential direction, the sealing cover can adapt to the slight changes in the position of the glue spraying mechanism while avoiding excessive deformation that would affect the sealing effect of the cleaning environment. The annular elastic protrusion is directly formed on the inner edge of the opening of the corrugated cylindrical structure, so that the sealing cover can be wrapped around the glue spraying mechanism in a wrapping manner, resulting in a better sealing effect.

[0013] According to the cleaning device for the glue spraying mechanism of a bag making machine provided in this application, the cleaning assembly further includes a flow guiding member, which is disposed inside a sealing cover, and the flow guiding member has a contoured hole aligned with the cleaning liquid outlet in the length direction.

[0014] By employing the above technical solution, a flow-guiding component is installed inside the sealed cover. This component guides the cleaning fluid, constrains its flow path, and prevents disorderly diffusion within the cleaning chamber, thus ensuring a stable and controllable cleaning process. Furthermore, the flow-guiding component features contoured holes aligned with the cleaning fluid outlet along its length. The shape of these holes can be adapted to the outer contour of the adhesive spraying mechanism, allowing the cleaning fluid to be directionally guided according to the actual geometric characteristics of the mechanism. This ensures the cleaning fluid is precisely concentrated in areas prone to residue, preventing scattering or waste and effectively removing stubborn adhesive residue. This also facilitates the restoration of smooth adhesive dispensing after cleaning.

[0015] According to the cleaning device for the glue spraying mechanism of a bag making machine provided in this application, the diversion component is set as a diversion plate fixed to the cleaning liquid outlet of the cleaning assembly, and the contour hole is a strip hole formed on the diversion plate.

[0016] According to the cleaning device for the glue spraying mechanism of a bag making machine provided in this application, the cleaning component includes an atomizing core, the inlet end of which is connected to the cleaning liquid filling port and the outlet end of which is connected to the cleaning liquid outlet; and an air inlet is formed on the side of the atomizing core near the inlet end; and a waste liquid outlet is formed on the bottom wall of the sealing cover.

[0017] By employing the above technical solution, the cleaning component includes an atomizing core, which transforms the cleaning fluid into fine mist particles. This allows the cleaning fluid to more evenly cover the surface of the adhesive spraying mechanism during cleaning, effectively penetrating into the tiny gaps in the adhesive residue for a more thorough removal of stubborn residue. Furthermore, an air inlet is formed on the side of the atomizing core near the inlet end. This inlet introduces external air, which mixes with the cleaning fluid inside the atomizing core. On one hand, the gas-liquid interaction enhances the atomization process, resulting in finer and more uniformly distributed droplets, improving the cleaning fluid's solubility and coverage, and providing a better softening effect on solidified adhesive residue. On the other hand, introducing external air also pressurizes the cleaning fluid's air passages, resulting in a more effective impact cleaning of the adhesive residue.

[0018] The cleaning device for the glue spraying mechanism of a bag making machine provided in this application also includes a pushing component; the pushing component is fixedly mounted on the frame, and the driving end of the pushing component is connected to the cleaning component to drive the cleaning component to move along the length direction.

[0019] By adopting the above technical solution, a pushing component is set up, and the driving end of the pushing component is connected to the cleaning component, which drives the cleaning component to move along the length direction. This allows the cleaning component to automatically move to the position of the spray nozzle, and the sealing joint tightly fits the outer peripheral wall of the spray nozzle to prevent cleaning fluid leakage, thus achieving a higher degree of automation.

[0020] According to the cleaning device for the glue spraying mechanism of a bag making machine provided in this application, the pushing component includes a driving body and a driving block that is slidably connected to the driving body along the length direction, and the side wall of the driving block away from the driving body is fixedly connected to the cleaning component.

[0021] By adopting the above technical solution, the side wall of the drive block away from the drive body is directly fixed to the cleaning component, which makes the cleaning component more stable during movement, thereby achieving precise sealing docking with the glue spraying mechanism.

[0022] According to the cleaning device for the glue spraying mechanism of a bag making machine provided in this application, a fixed base is fixedly connected to the frame, the drive body is fixedly connected to the fixed base, a connecting plate is fixedly connected to the cleaning component, and the side wall of the drive block away from the drive body is fixedly connected to the connecting plate.

[0023] This application also provides a glue spraying device for a bag making machine, including a glue spraying mechanism and a cleaning device for the glue spraying mechanism of the bag making machine in the above structure; the glue spraying mechanism includes a flipping frame and a glue spraying head mounted on the flipping frame, the flipping frame is rotatably connected to the frame of the bag making machine, and the cleaning component is mounted on the frame of the bag making machine and located on one side of the glue spraying mechanism; the flipping frame flips so that the glue spraying head is facing the glue base material to be sprayed or facing the opening of the sealing cover of the cleaning device.

[0024] By adopting the above technical solution, the glue spraying mechanism includes a flipping frame and a glue spraying head mounted on the flipping frame. The glue spraying head can move with the flipping frame. The flipping frame can rotate so that the glue spraying head is directly facing the substrate to be sprayed or the opening of the sealing cover of the cleaning device. During the glue spraying stage, the glue is applied to the substrate. During the non-working stage, the glue spraying head can be aligned with the opening of the cleaning device to perform a cleaning operation and remove residual glue. This not only prevents the glue spraying mechanism from overflowing and contaminating the bag or failing to spray glue due to blockage during use, ensuring that the bag is always sealed with an appropriate amount of glue and has good structural stability, but also avoids the risk of contaminating the bag during the cleaning process. This is conducive to further improving the bag making stability of the bag making equipment, thereby improving the pass rate and aesthetics of the bag production. Attached Figure Description

[0040] This application provides a cleaning device for the glue spraying mechanism of a bag making machine, such as... Figures 1 to 3 As shown, it includes: rack 10 (reference) Figure 5 ), cleaning component 100 and sealing cover 200.

[0041] Regarding the cleaning component 100, its main function is to dissolve or rinse away residual adhesive on the adhesive spraying mechanism 400 with cleaning fluid. The cleaning component 100 is mounted on the frame 10 (see...). Figure 5 The cleaning assembly 100 has a filling port 101 at one end and a cleaning fluid outlet 102 communicating with the filling port 101 at the other end. Specifically, the cleaning assembly 100 can deliver the cleaning fluid through pipes, guide channels or other forms of fluid channels, such as multi-segment connecting pipes or integrated flow guide structures, to ensure that the cleaning fluid can reach the glue spraying mechanism 400 efficiently.

[0042] Regarding the sealing cover 200, the sealing cover 200 is a structure used to form a closed space. Its main function is to accommodate the glue spraying mechanism 400 and prevent the cleaning fluid or residual glue from leaking out during the cleaning process. Specifically, one end of the sealing cover 200 is provided around the cleaning fluid outlet 102 at the other end of the cleaning assembly 100, and the other end of the sealing cover 200 extends outward along the length direction of the cleaning assembly 100 and forms a cleaning chamber 201 inside; furthermore, the end face of the sealing cover 200 away from the cleaning assembly 100 is also provided with a sealing joint portion 210 that is adapted to engage with the outer peripheral wall of the glue spraying mechanism 400.

[0043] More specifically, in this application, the sealing cover 200 can be made of a flexible material, such as rubber or silicone, to adapt to different shapes of the glue spraying mechanism 400. The sealing joint 210 can be configured as a flat sealing gasket, an annular sealing cover opening, or a multi-segment sealing strip, so that the sealing cover 200 can fit tightly against the outer peripheral wall of the glue spraying mechanism 400.

[0044] The cleaning device provided in this application effectively solves the problems of glue overflow from the glue spraying mechanism 400 contaminating the bag or preventing glue from being dispensed due to blockage. Specifically, during use, cleaning fluid is injected into the cleaning assembly 100 through the filling port 101 and directed to the glue spraying mechanism 400 through the cleaning fluid outlet 102, thereby dissolving or rinsing off residual glue on the glue spraying mechanism 400, preventing glue overflow from accumulating and causing blockage of the outlet, and thus avoiding the situation where glue cannot be dispensed normally or the bag is contaminated due to glue overflow during secondary use. One end of the sealing cover 200 forms a sealed connection around the cleaning fluid outlet 102, and the other end extends outward along the length of the cleaning assembly 100 and forms a cleaning chamber 201 inside, which is used to accommodate the glue spraying mechanism 400 for cleaning operations. Furthermore, the end face of the sealing cover 200 away from the cleaning assembly 100 is provided with a sealing joint 210 that is adapted to engage with the outer peripheral wall of the glue spraying mechanism 400. When the glue spraying mechanism 400 enters the cleaning chamber 201, the sealing joint 210 can fit tightly with the outer peripheral wall of the glue spraying mechanism 400, making the cleaning chamber 201 completely sealed. Thus, during the cleaning process, the cleaning fluid and residual glue are confined within the cleaning chamber 201, preventing leakage and contamination of the bag. Through this design, the cleaning device effectively solves the problem of glue overflow from the glue spraying mechanism 400 contaminating the bag or preventing glue from being dispensed due to blockage, while also avoiding the risk of secondary contamination during the cleaning process, thereby improving the stability of the bag-making equipment and the quality of the bag production.

[0045] The specific structure of the sealing cover 200 disposed outside the cleaning assembly 100 is not limited. For example, it can be a rigid cylindrical structure or a retractable elastic structure.

[0046] In one implementation, such as Figure 2 and Figure 4 As shown, the sealing cover 200 is a telescopic component that can deform along its length. The sealing joint 210 is an annular elastic protrusion structure fixed to the end face of the other end of the sealing cover 200. The annular elastic protrusion structure is an elastic annular protrusion component, which can be made of rubber or silicone material and is fixed to the end face of the sealing cover 200 by bonding or integral molding. Its purpose is to adapt to the shape changes and contact pressure of the outer peripheral wall of the glue spraying mechanism 400 to achieve sealing. The sealing cover 200 can be set as a telescopic component that deforms along its length, for example, it can be a bellows structure or a folded cylindrical structure, the purpose of which is to adaptively expand and contract according to the position changes of the glue spraying mechanism 400.

[0047] Specifically, the annular elastic protrusion structure is fixed to the end face of the sealing cover 200. When it comes into contact with the outer peripheral wall of the glue spraying mechanism 400, it can generate elastic deformation based on the contact pressure, thereby forming a tight seal. Even if there are dimensional deviations or surface irregularities on the outer peripheral wall of the glue spraying mechanism 400, the annular elastic protrusion structure can maintain good sealing performance through its own elastic properties. At the same time, the sealing cover 200 adopts a telescopic component design that can deform along the length direction. When the glue spraying mechanism 400 shifts in position, the sealing cover 200 can extend and retract accordingly, ensuring that the sealing joint 210 always maintains an adapted engagement with the outer peripheral wall of the glue spraying mechanism 400. This allows the glue spraying mechanism 400 to be cleaned in a closed environment in various applications, further reducing the risk of contamination of the bag by the mixture of cleaning fluid and glue during the cleaning process.

[0048] Furthermore, in this application, the sealing cover 200 is configured as a corrugated cylindrical structure, and the annular elastic protrusion structure is configured as an annular elastic protrusion formed on the inner edge of the opening of the corrugated cylindrical structure.

[0049] Those skilled in the art should understand that a corrugated cylindrical structure refers to a cylindrical component with continuous wavy folds. It can be made of thin-walled metal corrugated pipe, injection-molded plastic corrugated pipe, or rubber-pressed corrugated pipe, etc. This structure provides good elongation and contraction performance while possessing sufficient support strength in the circumferential direction. An annular elastic boss can be understood as a protruding structure surrounding the inner edge of the opening of the corrugated cylindrical structure. It can be integrally formed with the corrugated cylindrical structure through a one-piece molding process, or it can be fixed to the opening end of the corrugated cylindrical structure through insert assembly.

[0050] Specifically, this application sets the sealing cover 200 as a corrugated cylindrical structure. Since the corrugated structure has the advantages of high flexibility in its length direction and high support in its circumferential direction, the sealing cover 200 can adapt to slight changes in the position of the glue spraying mechanism 400 while avoiding excessive deformation that would affect the sealing effect of the cleaning environment. The annular elastic protrusion is directly formed on the inner edge of the opening of the corrugated cylindrical structure, so that the sealing cover 200 can be wrapped around the glue spraying mechanism 400 in a wrapping manner, resulting in a better sealing effect.

[0051] Based on the above description, the cleaning component 100 will be further described below.

[0052] In one embodiment of this application, such as Figure 2 As shown, the cleaning assembly 100 also includes a drainage member 110, which is disposed inside the sealing cover 200, and the drainage member 110 has a contoured hole 111 that is aligned with the cleaning fluid outlet 102 in the length direction.

[0053] Those skilled in the art should understand that the flow guiding component 110 refers to a component capable of guiding the flow path of the cleaning fluid, which can be a component with a guide groove or guide plate structure. In practical applications, the flow guiding component 110 can be made of corrosion-resistant materials, such as stainless steel or engineering plastics, to accommodate different types of cleaning fluids. Its purpose is to constrain the flow path of the cleaning fluid, preventing disorderly diffusion of the cleaning fluid within the cleaning chamber 201, thereby ensuring a stable and controllable cleaning process. The contoured hole 111 refers to a through hole of a specific shape designed according to the outer periphery of the adhesive spraying mechanism 400. It can be adapted to the actual geometric characteristics of the adhesive spraying head 410, allowing the cleaning fluid to be precisely concentrated in areas prone to residue.

[0054] Specifically, this application provides a flow guiding component 110 within the sealing cover 200. The flow guiding component 110 guides the cleaning fluid, constrains its flow path, and prevents disorderly diffusion within the cleaning chamber 201, thereby ensuring a stable and controllable cleaning process. Furthermore, the flow guiding component 110 has a contoured hole 111 aligned with the cleaning fluid outlet 102 along its length. The shape of the contoured hole 111 can be adapted to the outer periphery of the adhesive spraying mechanism 400, allowing the cleaning fluid to be directionally guided according to the actual geometric characteristics of the adhesive spraying mechanism 400. This ensures the cleaning fluid is precisely concentrated in areas prone to residue, preventing scattering or waste, effectively removing stubborn adhesive residue, and facilitating the restoration of smooth adhesive dispensing after cleaning of the adhesive spraying mechanism 400.

[0055] Furthermore, in this application, the drainage member 110 can be configured as a drainage plate fixed to the cleaning fluid outlet 102 of the cleaning assembly 100, and the contour hole 111 is a strip hole formed on the drainage plate.

[0056] Specifically, the drainage component 110 can be installed at the cleaning fluid outlet 102 by welding, bolting or other fixing methods to ensure a rigid connection with the cleaning fluid outlet 102, thereby avoiding the diffusion or leakage of cleaning fluid due to vibration or pressure changes.

[0057] Furthermore, the cleaning component 100 is not limited to being configured as a pipe, flow channel, or other similar structure. In one embodiment of this application, such as Figures 2 to 3 As shown, the cleaning assembly 100 may include an atomizing core 120, the inlet end of which is connected to the cleaning fluid filling port 101 and the outlet end of which is connected to the cleaning fluid outlet 102; and an air inlet 121 is formed on the side of the atomizing core 120 near the inlet end; and a waste liquid outlet 220 is formed on the bottom wall of the sealing cover 200.

[0058] Those skilled in the art will understand that the atomizing core 120 refers to a device capable of converting liquid into fine mist particles, which can be an ultrasonic atomizer, a pressure nozzle atomizer, or a centrifugal atomizer, etc. In practical applications, the air inlet 121 is a channel structure for introducing external air, specifically controlled by a one-way valve or a regulating valve to control the gas flow rate. The waste liquid outlet 220 refers to an opening for discharging residual liquid generated during the cleaning process, such as a drain hole with a filter screen or a siphon drain pipe.

[0059] Specifically, the cleaning component 100 in this application includes an atomizing core 120, which can convert the cleaning liquid into fine mist particles. This allows the cleaning liquid to more evenly cover the surface of the adhesive spraying mechanism 400 during cleaning, effectively penetrating into the tiny gaps in the adhesive residue and more thoroughly removing stubborn adhesive residue. Furthermore, an air inlet 121 is formed on the side of the atomizing core 120 near the inlet end. The air inlet 121 introduces external air to mix with the cleaning liquid inside the atomizing core 120. On one hand, the gas-liquid interaction enhances the atomization process, resulting in finer and more uniform droplet size, improving the dissolving power and coverage of the cleaning liquid, and providing a better softening effect on solidified adhesive residue. On the other hand, the introduction of external air also pressurizes the cleaning liquid air passage, resulting in a better impact cleaning effect on the adhesive residue.

[0060] Furthermore, cleaning devices based on the above structure, such as Figures 1 to 3 As shown, the cleaning device may also include a pushing component 300; the pushing component 300 is fixedly mounted on the frame 10, and the driving end of the pushing component 300 is connected to the cleaning component 100 to drive the cleaning component 100 to move along the length direction.

[0061] Those skilled in the art will understand that the push assembly 300 is a mechanism capable of providing driving force and adjusting the position of the cleaning assembly 100, such as a linear drive device like a cylinder, hydraulic cylinder, or electric push rod. The drive end refers to the part of the push assembly 300 that is directly connected to the cleaning assembly 100 and transmits driving force, and can be connected by bolts, snap-fit ​​connections, or other mechanical connection methods.

[0062] Specifically, this application sets up a push component 300, the drive end of the push component 300 is connected to the cleaning component 100, and drives the cleaning component 100 to move along the length direction, so that the cleaning component 100 can automatically move to the position of the spray nozzle 410, and use the sealing joint 210 to tightly fit the outer peripheral wall of the spray nozzle 410 to prevent cleaning fluid leakage, thus achieving a higher degree of automation.

[0063] The following provides further explanation of the driving component 300.

[0064] The structure of the actuating component 300 is not limited, and can include any of the linear drive devices such as cylinders, hydraulic cylinders or electric push rods as described above, and corresponding connection structures.

[0065] In one embodiment, the pushing assembly 300 includes a driving body 310 and a driving block 320 slidably connected to the driving body 310 along its length. The side wall of the driving block 320 away from the driving body 310 is fixedly connected to the cleaning assembly 100. A fixing seat 330 is fixedly connected to the frame 10, the driving body 310 is fixedly connected to the fixing seat 330, and a connecting plate 340 is fixedly connected to the cleaning assembly 100. The side wall of the driving block 320 away from the driving body 310 is fixedly connected to the connecting plate 340.

[0066] Those skilled in the art should understand that the drive body 310 refers to the structure that provides power, such as any of the linear drive devices described above, such as a cylinder, hydraulic cylinder, or electric push rod; the drive block 320 can be a sliding component that moves linearly along the length of the drive body 310, such as a slide plate that can be slidably connected to the drive body 310 via a ball bearing guide, linear guide, or slide groove structure, the purpose of which is to accurately transmit driving force and ensure stability during movement. The fixed seat 330 refers to a structural component that provides stable support for the drive body 310, and it can be a metal plate that is fixedly connected to the frame 10 by welding or bolting through connecting rods. The connecting plate 340 is an intermediate connecting component that can be fixedly connected to the cleaning assembly 100 and the drive block 320 by bolts, riveting, or welding, the purpose of which is to reduce the impact of movement on the cleaning assembly 100 and improve assembly convenience through indirect connection.

[0067] This application directly fixes the side wall of the drive block 320 away from the drive body 310 to the cleaning assembly 100, which makes the cleaning assembly 100 more stable during movement, thereby achieving precise sealing docking with the glue spraying mechanism 400.

[0068] This application also provides a glue spraying device for a bag making machine, such as... Figure 5 As shown, the structure includes a glue spraying mechanism 400 and a cleaning device for the glue spraying mechanism of the bag making machine. The glue spraying mechanism 400 includes a flipping frame 420 and a glue spraying head 410 mounted on the flipping frame 420. The flipping frame 420 is rotatably connected to the frame 10 of the bag making machine. The cleaning assembly 100 is mounted on the frame 10 of the bag making machine and located on one side of the glue spraying mechanism 400. The flipping frame 420 flips so that the glue spraying head 410 is facing the glue-to-be-sprayed base material or the opening of the sealing cover 200 of the cleaning device.

[0069] Those skilled in the art should understand that the spray head 410 can be a ball-type spray head or a spray gun-type spray head; this application does not make it the only requirement.

[0070] The glue spraying device provided in this application includes a glue spraying mechanism 400 comprising a flipping frame 420 and a glue spraying head 410 mounted on the flipping frame 420. The glue spraying head 410 can move with the flipping frame 420, and the flipping frame 420 can be flipped so that the glue spraying head 410 is facing either the substrate to be sprayed or the opening of the sealing cover 200 of the cleaning device. During use, the glue spraying head can be aligned with the substrate to complete the glue application, and during non-working periods, it can be aligned with the opening of the cleaning device for cleaning operations to remove residual glue. This not only prevents the glue spraying mechanism 400 from overflowing and contaminating the bag or failing to dispense glue due to blockage, ensuring that the bag is always sealed with the appropriate amount of glue and has good structural stability, but also avoids the risk of contaminating the bag during the cleaning process, which is beneficial for further improving the bag-making stability of the bag-making equipment, thereby improving the pass rate and aesthetics of the bag production.

In addition, in order to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description.
