Description

Technical Field

[0001] This application relates to the field of mask sealing technology, and in particular to a mask sealing machine. Background Technology

[0002] In the field of cosmetic packaging technology, facial mask products are often sealed in aluminum foil bags. The packaging process requires placing the mask sheet and essence into the aluminum foil bag and then sealing the bag. Existing mask sealing machines mostly achieve heat sealing by clamping the aluminum foil bag opening with a heating strip, but they generally suffer from a core defect: the lack of a dedicated aluminum foil bag positioning structure, resulting in the aluminum foil bag being placed arbitrarily and inconsistently during sealing. This problem directly causes irregular sealing marks, affecting the consistency of product appearance, and may even lead to incomplete sealing due to sealing misalignment, reducing product packaging quality. Furthermore, some sealing machines have a horizontal placement area, which easily allows the essence inside the aluminum foil bag to leak out during the sealing operation, further affecting production efficiency and product quality. To solve these problems, there is an urgent need for a mask sealing machine with precise positioning capabilities that can reduce liquid leakage. Therefore, this mask sealing machine is provided. Utility Model Content

[0003] The purpose of this application is to provide a mask sealing machine with precise positioning function and the ability to reduce liquid leakage.

[0004] The mask sealing machine provided in this application adopts the following technical solution: it includes an inclined placement platform for placing aluminum foil bags, a sealing assembly for heat sealing, and a driving assembly for driving the sealing assembly. A limiting mechanism is provided at the upper end of the inclined placement platform. The limiting mechanism includes a housing. A groove for accommodating the housing is formed on the bearing surface of the inclined placement platform, and the housing passes through the groove. The top surface of the housing is flush with the bearing surface of the inclined placement platform. A dual-axis motor is fixedly connected inside the housing. The two output shafts of the dual-axis motor extend horizontally. A threaded column is fixedly connected to the end of each of the two sets of output shafts away from the dual-axis motor. The ends of the two sets of threaded columns away from the dual-axis motor are rotatably connected inside the housing with opposite thread directions. Threaded caps are threadedly connected to the outer surfaces of the two sets of threaded columns, and connecting rods are fixedly connected to the outer surfaces of the two sets of threaded caps. A limiting groove extending horizontally is formed on the upper surface of the housing. The end of the connecting rod away from the threaded cap passes through the limiting groove and extends to the outside of the housing. A limiting plate is fixedly connected to the end of each set of connecting rods located on the outside of the housing. By adopting the above technical solution and setting a limiting mechanism at the top of the inclined placement platform, a complete aluminum foil bag positioning structure is constructed. The shell provides a stable mounting base for each component of the limiting mechanism, ensuring the overall structure is solid and reliable. The dual-axis motor serves as the power source, and its output shaft drives two sets of threaded columns with opposite thread directions to rotate synchronously. This causes the two sets of threaded caps to move smoothly relative to or in opposite directions along the threaded columns, which in turn drives the two sets of limiting plates to open and close precisely through the connecting rod. The limiting groove on the shell guides and limits the connecting rod, preventing deviation or jamming during movement. Ultimately, the two sets of limiting plates accurately clamp and position the left and right sides of the aluminum foil bag, fundamentally solving the problem of irregular sealing marks caused by the non-fixed placement position of the aluminum foil bag in the existing technology. This ensures the consistency of the sealing position and lays a core foundation for improving sealing quality.

[0005] Preferably, a pressure sensor for detecting clamping pressure is embedded inside the limiting plate, and a controller is provided on the left side of the sealing assembly. The controller is electrically connected to the dual-axis motor and the pressure sensor.

[0006] By adopting the above technical solution, a pressure sensor is embedded inside the limiting plate, which can detect the clamping pressure of the limiting plate on the aluminum foil bag in real time and accurately, avoiding pressure control imbalance caused by improper manual operation; the controller set on the left side of the sealing assembly forms a complete electronic control closed loop with the dual-axis motor and the pressure sensor, which can automatically adjust the operating status of the dual-axis motor according to the signal fed back by the pressure sensor.

[0007] Preferably, the sealing component and the limiting mechanism are correspondingly arranged. The sealing component includes heating strips arranged opposite each other, both sets of heating strips are black heat-conducting structures, and the two sets of heating strips are correspondingly arranged to form a sealing area. The lower heating strip is arranged at the upper end of the inclined placement platform plane.

[0008] By adopting the above technical solution, the sealing component and the limiting mechanism are set up accordingly, and the upper and lower heating strips form the sealing area. The heating strips are black heat-conducting structures, which improve heating efficiency and heat sealing uniformity. Combined with the positioning effect of the limiting mechanism, the sealing quality and appearance regularity are further guaranteed.

[0009] Preferably, the drive assembly includes an electric push rod and a guide rod, and the drive assembly is equipped with a foot sensor. The foot sensor is electrically connected to the electric push rod, and the lower ends of the electric push rod and the guide rod are fixedly connected to the upper surface of the upper heating strip.

[0010] By adopting the above technical solution, the drive component uses an electric push rod and a guide rod to cooperate, which ensures stable transmission and precise action. It can drive the upper heating strip to move smoothly vertically, ensuring uniform sealing pressure and further improving sealing quality. Moreover, there is no need to manually operate the sealing component, reducing labor intensity, adapting to mass production scenarios, and improving production efficiency.

[0011] Preferably, the inclined placement platform is a slope structure, with its slope extending from a low point to a high point and facing the sealing area of ​​the sealing component.

[0012] By adopting the above technical solution, the inclined placement platform is a sloping structure with the slope extending from low to high and facing the sealing area of ​​the sealing component, so that the opening of the aluminum foil bag is naturally aligned with the sealing area, while reducing the outflow of essence inside the bag, reducing material loss, and maintaining a clean production environment.

[0013] Preferably, the working surfaces of the limiting plates are all smooth.

[0014] By adopting the above technical solution, the working surface of the limiting plate is set to a smooth structure, which can reduce friction with the surface of the aluminum foil bag during clamping, prevent the aluminum foil bag from being scratched or damaged due to clamping, and protect the integrity of the packaging.

[0015] Preferably, the guide rod surface is provided with a wear-resistant coating.

[0016] By adopting the above technical solution, the wear-resistant coating on the surface of the guide rod can enhance the wear resistance of the guide rod, reduce wear during long-term use, and extend the service life of the drive assembly.

[0017] Preferably, the length of the limiting groove is adapted to the length of the threaded post, and the width of the limiting groove is adapted to the diameter of the connecting rod.

[0018] By adopting the above technical solution, the length of the limiting groove is matched with the threaded column and the width is matched with the diameter of the connecting rod. This can accurately limit the movement trajectory of the threaded cap and the connecting rod, ensure that the two sets of limiting plates move in parallel, avoid uneven force on the aluminum foil bag during clamping, and ensure positioning accuracy and sealing consistency.

[0019] In summary, this application includes at least one of the following beneficial technical effects: This mask sealing machine uses a dual-axis motor to drive two sets of opposing threaded columns to rotate, which in turn moves the threaded caps and connecting rods along the limiting grooves. This allows the two limiting plates to precisely clamp the aluminum foil bag, preventing positional deviation during sealing and significantly improving the regularity of the sealing marks. This solves the core problem of irregular sealing in existing technologies. Pressure sensors inside the limiting plates monitor the clamping pressure in real time, and the controller starts and stops the dual-axis motor based on the pressure signal. This prevents excessive pressure from damaging the aluminum foil bag or insufficient pressure from causing insecure positioning, improving operational safety and positioning accuracy. The inclined placement table's slope structure directs the aluminum foil bag opening towards the sealing area, reducing the outflow of essence from the bag, minimizing material loss, and ensuring a clean production environment. This solves the problem of easy liquid leakage in existing technologies. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0023] Example 1: Facial mask sealing machine, refer to Figure 1 , Figure 3 and Figure 4The system includes an inclined placement platform 3 for placing aluminum foil bags, a sealing assembly 2 for heat sealing, and a drive assembly 1 for driving the sealing assembly 2. A limit mechanism 4 is provided at the upper end of the inclined placement platform 3. The limit mechanism 4 includes a housing 41. A groove for accommodating the housing 41 is formed on the bearing surface of the inclined placement platform 3, and the housing 41 is inserted inside the groove. The top surface of the housing 41 is flush with the bearing surface of the inclined placement platform 3. A dual-axis motor 42 is fixedly connected inside the housing 41. The two output shafts of the dual-axis motor 42 extend horizontally. A threaded post 43 is fixedly connected to the end of each of the two sets of output shafts away from the dual-axis motor 42. The ends of the two sets of threaded posts 43 away from the dual-axis motor 42 are rotatably connected inside the housing 41 with opposite thread directions. Threaded caps 44 are threadedly connected to the outer surfaces of the two sets of threaded posts 43, and connecting rods 45 are fixedly connected to the outer surfaces of the two sets of threaded caps 44. A limit groove 46 extending horizontally is formed on the upper surface of the housing 41. The end of the connecting rod 45 away from the threaded cap 44 passes through the limit groove. The slot 46 extends to the outside of the housing 41; the two sets of connecting rods 45 are fixedly connected to the limiting plate 47 at one end on the outside of the housing 41. By setting the limiting mechanism 4 at the upper end of the inclined placement platform 3, a complete aluminum foil bag positioning structure is constructed. The housing 41 provides a stable installation base for each component of the limiting mechanism 4, ensuring that the overall structure is firm and reliable. The dual-axis motor 42 serves as a power source, and its output shaft drives the two sets of threaded columns 43 with opposite thread directions to rotate synchronously, causing the two sets of threaded caps 44 to move smoothly relative to or in opposite directions along the threaded columns 43. Then, the connecting rods 45 drive the two sets of limiting plates 47 to open and close precisely. The limiting slot 46 on the housing 41 guides and limits the connecting rods 45, preventing deviation or jamming during movement. Finally, the two sets of limiting plates 47 accurately clamp and position the left and right sides of the aluminum foil bag, fundamentally solving the problem of irregular sealing marks caused by the non-fixed placement position of the aluminum foil bag in the prior art, ensuring the consistency of the sealing position, and laying a core foundation for improving sealing quality.

[0024] Reference Figure 1 , Figure 3 and Figure 5The limiting plate 47 is internally fitted with a pressure sensor for detecting clamping pressure. A controller 5 is located on the left side of the sealing assembly 2. The controller 5 is electrically connected to the dual-axis motor 42 and the pressure sensor. The sealing assembly 2 and the limiting mechanism 4 are correspondingly arranged. The sealing assembly 2 includes two sets of heating strips 21 arranged opposite each other. Both sets of heating strips 21 are black heat-conducting structures, and the two sets of heating strips 21 are correspondingly arranged to form a sealing area. The lower heating strip 21 is located at the upper end of the inclined placement platform 3. The pressure sensor is internally fitted with the limiting plate 47, which can detect the limiting pressure in real time and accurately. The clamping pressure of plate 47 on the aluminum foil bag avoids pressure control imbalance caused by improper manual operation; the controller 5 set on the left side of the sealing component 2 forms a complete electronic control closed loop with the dual-axis motor 42 and pressure sensor. It can automatically adjust the running status of the dual-axis motor 42 according to the signal fed back by the pressure sensor. The sealing component 2 and the limiting mechanism 4 are set accordingly. The upper and lower opposite heating strips 21 form the sealing area. The heating strips 21 are black heat-conducting structures, which improve heating efficiency and heat sealing uniformity. Combined with the positioning effect of the limiting mechanism 4, it further ensures sealing quality and appearance regularity.

[0025] Reference Figure 1 , Figure 2 and Figure 5 The drive assembly 1 includes an electric push rod 11 and a guide rod 12. The drive assembly 1 is equipped with a foot sensor 13, which is electrically connected to the electric push rod 11. The lower ends of the electric push rod 11 and the guide rod 12 are fixedly connected to the upper surface of the upper heating strip 21. The inclined placement platform 3 is a sloping structure with its slope extending from low to high and facing the sealing area of ​​the sealing assembly 2. The drive assembly 1 uses the electric push rod 11 and the guide rod 12 in cooperation, which provides stable transmission and precise action. It can drive the upper heating strip 21 to move smoothly vertically, ensuring uniform sealing pressure and further improving sealing quality. Moreover, it eliminates the need for manual operation of the sealing assembly 2, reducing labor intensity and adapting to mass production scenarios, thereby improving production efficiency. The inclined placement platform 3 is a sloping structure with its slope extending from low to high and facing the sealing area of ​​the sealing assembly 2, so that the opening of the aluminum foil bag is naturally aligned with the sealing area, while reducing the outflow of essence inside the bag, reducing material loss, and maintaining a clean production environment.

[0026] Reference Figure 1 , Figure 3 and Figure 4The working surfaces of the limiting plates 47 are all smooth, and the surface of the guide rod 12 is coated with a wear-resistant coating. The length of the limiting groove 46 is matched with the length of the threaded post 43, and the width of the limiting groove 46 is matched with the diameter of the connecting rod 45. The smooth working surfaces of the limiting plates 47 reduce friction with the surface of the aluminum foil bag during clamping, preventing the aluminum foil bag from being scratched or damaged during clamping, thus protecting the integrity of the packaging. The wear-resistant coating on the surface of the guide rod 12 enhances the wear resistance of the guide rod 12, reduces wear during long-term use, and extends the service life of the drive assembly 1. The length of the limiting groove 46 is matched with the threaded post 43, and the width is matched with the diameter of the connecting rod 45, which can accurately limit the movement trajectory of the threaded cap 44 and the connecting rod 45, ensuring that the two sets of limiting plates 47 move in parallel, avoiding uneven force on the aluminum foil bag during clamping, and ensuring positioning accuracy and sealing consistency.

[0027] In this embodiment, the dual-axis motor 42 drives two sets of reverse threaded columns 43 to rotate, which in turn moves the threaded cap 44 and the connecting rod 45 along the limiting groove 46. This allows the two sets of limiting plates 47 to accurately clamp the aluminum foil bag, preventing positional deviation during sealing and significantly improving the regularity of the sealing marks. This solves the core problem of irregular sealing in the prior art. The pressure sensor inside the limiting plate 47 detects the clamping pressure in real time, and the controller 5 controls the start and stop of the dual-axis motor 42 based on the pressure signal. This prevents excessive pressure from damaging the aluminum foil bag or insufficient pressure from causing insecure positioning, thus improving operational safety and positioning accuracy. The inclined structure of the tilting platform 3 causes the opening of the aluminum foil bag to face the sealing area, reducing the outflow of the essence inside the bag, reducing material loss, and ensuring a clean production environment. This solves the problem of easy liquid outflow in the prior art.

[0028] The implementation principle of this embodiment is as follows: Before production, the controller 5 presets the operating parameters of the dual-axis motor 42 and the pressure threshold of the pressure sensor. The heating strip 21 of the sealing assembly 2 begins to heat up, and the electric push rod 11 of the drive assembly 1 is in standby mode. The aluminum foil bag containing the face mask is placed on the slope of the inclined placement platform 3. The slope direction makes the opening of the aluminum foil bag face the sealing area of ​​the sealing assembly 2, reducing the leakage of essence inside the bag. The limiting mechanism 4 is activated, and the controller 5 controls the dual-axis motor 42 to run. Its output shaft drives two sets of reverse threaded columns 43 to rotate synchronously. The threaded cap 44 moves relative to the threaded column 43 and drives two sets of limiting plates 47 to move closer together through the connecting rod 45. The connecting rod 45 moves smoothly along the limiting groove 46 on the housing 41 to ensure that the limiting plates 47 clamp the two sides of the aluminum foil bag in parallel. When the clamping pressure detected by the pressure sensor reaches the preset threshold, a signal is sent to the controller 5, and the controller 5 controls the dual-axis motor 42 to stop running, completing the precise positioning of the aluminum foil bag. The operator steps on the foot sensor 13, triggering the drive assembly 1. The electric push rod 11 drives the upper heating strip 21 of the sealing assembly 2 to move downwards, clamping the aluminum foil bag opening together with the lower heating strip 21, thus achieving heat sealing. After sealing, the foot sensor 13 resets, the upper heating strip 21 moves upwards, the controller 5 controls the dual-axis motor 42 to run in reverse, the two sets of limit plates 47 separate, and the operator removes the sealed aluminum foil bag, completing one sealing process.
