[0002] A mask sealing machine is an automated device used to place masks into packaging bags and seal them, playing a significant role. It improves the hygiene and safety of masks by effectively sealing them to prevent external contaminants from entering, extending the lifespan of the masks, and facilitating their storage and transportation. Its applications are wide-ranging. In the medical field, high-standard sealing machines meet the sterile environment requirements of hospitals for packaging medical protective masks. In the industrial field, durable sealing machines meet workers' needs for protective equipment, ensuring the production of industrial protective masks. In the everyday consumer market, convenient sealing machines meet consumers' hygiene and safety needs, assisting in the packaging of everyday consumer masks and playing an indispensable role in ensuring mask supply.

[0003] An existing patent (publication number: CN217295134U) describes a sealing machine for mask production. This sealing machine reduces the humidity in the air around the heating box, thereby recovering the heat emitted around the heating box and reducing resource waste. However, the heat sealing strip of this sealing machine cannot be adjusted in angle according to different mask models, which makes it unable to meet the sealing processing needs of various masks, resulting in poor performance. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a multi-angle adjustable sealing machine for mask processing, which effectively solves the problem that the heat sealing strip of the existing sealing machine cannot be adjusted according to different models of masks, resulting in the inability to meet the sealing processing needs of various masks and poor performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle adjustable sealing machine for mask processing, comprising a base plate, a support frame fixedly installed on one side of the top of the base plate, an iron plate fixedly installed on the top of the base plate, two limiting strips symmetrically rotated on the top of the iron plate, a magnet fixedly installed at one end of each of the two limiting strips, the bottom of each magnet being magnetically attracted to the iron plate, two heat sealing strips provided above the iron plate, an electric push rod fixedly installed on the top of the support frame, the transmission end of the electric push rod penetrating downwards into the interior of the support frame and fixedly installed with a connecting frame, an installation box fixedly installed at the bottom of the connecting frame, a servo motor fixedly installed on one side of the top of the installation box, a transmission component provided at the output end of the servo motor, the transmission component being connected to the two heat sealing strips, when the servo motor is running, power is output to the two heat sealing strips through the transmission component, causing the two heat sealing strips to rotate and adjust their angle.

[0006] Preferably, the transmission assembly includes an external gear, which is fixedly installed at the output end of the servo motor. A positioning seat is rotatably installed on one side of the external gear. The bottom of the positioning seat is fixedly connected to the top of the mounting box. An internal gear is meshed with the lower part of the external gear. A threaded sleeve is fixedly installed inside the internal gear. The surface of the threaded sleeve is rotatably connected to the inside of the mounting box through a shaft seat. A threaded rod is threadedly connected inside the threaded sleeve.

[0007] Preferably, a connecting strip is fixedly installed at one end of the threaded rod, an upper positioning frame is fixedly installed at the front end of the top of the mounting box, a lower positioning frame is fixedly installed at the front end of the bottom of the mounting box, a shaft is rotatably installed on the upper and lower positioning frames, and two adjusting rods are rotatably installed on the surface of the shaft, with the lower parts of the two adjusting rods respectively fixedly connected to two heat sealing strips.

[0008] Preferably, each of the adjusting rods has a sliding rod fixedly installed inside, and each of the two sliding rods has a sliding sleeve fitted on its surface. Each sliding sleeve has a support arm fixedly installed on its surface. One end of each of the two support arms is fixedly connected to one end of the connecting strip. Two limiting sleeves are fixedly installed on the surface of the connecting strip. Each of the two limiting sleeves has a limiting rod inserted inside its interior. One end of each of the two limiting rods is fixedly connected to the bottom of the mounting box.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator places the mask on the iron plate, and then adjusts the angle of the two limiting strips according to the shape of the mask. The two limiting strips are positioned by two magnets so that they are aligned with the outer contour of the mask, ensuring the accuracy of subsequent sealing. Then, the operator starts the servo motor to drive the external gear to rotate along the positioning seat. When the external gear rotates, it drives the threaded sleeve to rotate along the inside of the shaft seat through the internal gear. When the threaded sleeve rotates, it drives the threaded rod to move.

[0010] When the threaded rod moves, it drives the two support arms to move via the connecting bar. The movement of the connecting bar also causes the two limiting sleeves to slide along the surfaces of the two limiting rods, increasing the stability of the connecting bar's movement. The movement of the two support arms causes the two sliding sleeves to slide along the surfaces of the two sliding rods, thereby causing the two adjusting rods to rotate along the two shafts. The rotation of the two adjusting rods causes the two heat-sealing strips to adjust their angles, aligning them with the angles of the two limiting strips. Then, the electric push rod is activated, causing the connecting frame and mounting box to move downwards. As the mounting box moves downwards, it causes the two heat-sealing strips to move downwards, achieving the sealing operation of the mask. This allows the heat-sealing strips of this sealing machine to have their angles adjusted according to different mask models, enabling it to meet the sealing needs of various mask types and providing excellent performance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1 to 6The present invention includes a base plate 1, a support frame 2 fixedly installed on one side of the top of the base plate 1, an iron plate 5 fixedly installed on the top of the base plate 1, two limiting strips 3 symmetrically rotated on the top of the iron plate 5, a magnet 4 fixedly installed at one end of each of the two limiting strips 3, and the bottom of each of the two magnets 4 magnetically attracted to the iron plate 5. Two heat sealing strips 6 are provided above the iron plate 5. An electric push rod 7 is fixedly installed on the top of the support frame 2. The transmission end of the electric push rod 7 extends downward into the interior of the support frame 2 and is fixedly installed with a connecting frame 8. An installation box 9 is fixedly installed at the bottom of the connecting frame 8. A servo motor 10 is fixedly installed on one side of the top of the installation box 9. The output end of the servo motor 10 is provided with a transmission component, which is connected to the two heat sealing strips 6. When the servo motor 10 is running, it outputs power to the two heat sealing strips 6 through the transmission component, causing the two heat sealing strips 6 to rotate and adjust their angle.

[0022] In use, the operator places the mask on the iron plate 5, then adjusts the angle of the two limiting strips 3 according to the shape of the mask, and positions the two limiting strips 3 with the two magnets 4 to align them with the outer contour of the mask, ensuring accuracy during subsequent sealing. The operator then starts the servo motor 10 to drive the transmission component, which in turn adjusts the angle of the two heat sealing strips 6 to match the angle of the two limiting strips 3. Next, the electric push rod 7 is activated to move the connecting frame 8 and the mounting box 9 downwards. As the mounting box 9 moves downwards, it moves the two heat sealing strips 6 downwards to seal the mask. This allows the heat sealing strips 6 of this sealing machine to be angled according to different mask models, enabling it to meet the sealing needs of various masks and providing excellent performance.

[0023] The transmission assembly includes an external gear 11, which is fixedly mounted on the output end of the servo motor 10. A positioning seat 12 is rotatably mounted on one side of the external gear 11. The bottom of the positioning seat 12 is fixedly connected to the top of the mounting box 9. An internal gear 13 is meshed with the lower part of the external gear 11. A threaded sleeve 14 is fixedly mounted inside the internal gear 13. The surface of the threaded sleeve 14 is rotatably connected to the inside of the mounting box 9 through a shaft seat 15. A threaded rod 16 is threadedly connected inside the threaded sleeve 14.

[0024] The operator starts the servo motor 10 to drive the external gear 11 to rotate along the positioning seat 12. When the external gear 11 rotates, it drives the threaded sleeve 14 to rotate along the inside of the shaft seat 15 through the internal gear 13. When the threaded sleeve 14 rotates, it drives the threaded rod 16 to move.

[0025] A connecting strip 17 is fixedly installed at one end of the threaded rod 16. An upper positioning frame 24 is fixedly installed at the front end of the top of the mounting box 9. A lower positioning frame 26 is fixedly installed at the front end of the bottom of the mounting box 9. A shaft 25 is rotatably installed on the upper positioning frame 24 and the lower positioning frame 26. Two adjusting rods 23 are rotatably installed on the surface of the shaft 25. The lower parts of the two adjusting rods 23 are fixedly connected to two heat sealing strips 6 respectively.

[0026] The adjusting rod 23 has a sliding rod 22 fixedly installed inside. The surface of the two sliding rods 22 is covered with a sliding sleeve 21. The surface of the sliding sleeve 21 is fixedly installed with a support arm 20. One end of the two support arms 20 is fixedly connected to one end of the connecting strip 17. The surface of the connecting strip 17 has two limiting sleeves 18 fixedly installed. The inside of the two limiting sleeves 18 is inserted with a limiting rod 19. One end of the two limiting rods 19 is fixedly connected to the bottom of the mounting box 9.

[0027] When the threaded rod 16 moves, it drives the two support arms 20 to move through the connecting bar 17. When the connecting bar 17 moves, it drives the two limit sleeves 18 to slide along the surface of the two limit rods 19, which increases the stability of the connecting bar 17 when it moves. When the two support arms 20 move, they drive the two sliding sleeves 21 to slide along the surface of the two sliding rods 22, which causes the two adjusting rods 23 to rotate along the two shafts 25. When the two adjusting rods 23 rotate, they drive the two heat sealing strips 6 to adjust their angles, so that the angles of the two heat sealing strips 6 and the two limit strips 3 are consistent.
