Description

Technical Field

[0001] This utility model belongs to the technical field of edge sealing devices, specifically a mask edge sealing device for the production of KN95 masks. Background Technology

[0002] The KN95 mask sealing device is a machine used in the production of folded mask bodies. It can precisely bond 3 to 5 layers of PP non-woven fabric, activated carbon, and filter materials. The device is characterized by high efficiency, simple operation, and stable quality. It has a wide range of applications and is suitable for high-pollution industries such as construction and mining. It can effectively block harmful substances such as dust and particulate matter, protecting the wearer's respiratory health. In addition, the device can quickly change molds according to different needs to produce different models of masks, meeting diverse market demands and playing a key role in mask production.

[0003] An existing patent (publication number: CN219276700U) discloses a mask sealing device that can quickly position masks for sealing. The positioning structure is adjustable to accommodate masks of different sizes. However, this device requires manual insertion of the mask into the lower part of the hot press head for sealing. After sealing, the mask is removed from the bottom of the hot press head. The hot press head is very hot, which can easily cause burns to the operator, posing a safety hazard. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a mask sealing device for the production of KN95 masks. It effectively solves the problem that the existing mask sealing device requires manual feeding of the mask into the lower part of the hot press head and removal from the lower part of the hot press head after sealing, which can easily lead to burns to the operator.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mask sealing device for KN95 mask production, comprising a workbench, with support legs fixedly installed at the four corners of the bottom of the workbench, an installation opening on one side of the workbench, a collection bucket inside the installation opening, and the collection bucket being fixedly connected to the workbench on both sides by connecting pieces and bolts, a support frame fixedly installed on one side of the top of the workbench, an electric push rod fixedly installed on the inner top of the support frame, a heat-sealing head fixedly installed at the transmission end of the electric push rod, a rotating disk above the middle of the workbench, four placement seats fixedly installed at equal intervals in a ring on the upper side of the rotating disk, a servo motor fixedly installed in the middle of the bottom of the workbench, a transmission component at the output end of the servo motor, the transmission component being connected to the rotating disk, the servo motor outputting power to the rotating disk through the transmission component, causing the rotating disk to rotate and feed materials, and an automatic opening and closing mechanism between the upper part of the workbench and the lower part of the rotating disk for opening or closing the placement seats.

[0006] Preferably, limiting rods are fixed on both sides of the top of the hot-pressed head, and limiting sleeves are fitted on the surface of the two limiting rods. Support rods are fixedly installed on the surface of the two limiting sleeves, and the tops of the two support rods are fixedly connected to the top of the support frame.

[0007] Preferably, the transmission assembly includes a drive shaft, which is fixedly installed at the output end of the servo motor. The top end of the drive shaft is fixedly connected to the middle of the bottom of the rotating disk. A positioning bushing is rotatably installed on the surface of the drive shaft. Three fixed legs are fixedly installed on the surface of the positioning bushing, and the bottom ends of the three fixed legs are fixedly connected to the top of the worktable.

[0008] Preferably, the automatic opening and closing mechanism includes four feeding plates, which are rotatably mounted on the lower part of the rotating disk via a rotating shaft, and the four feeding plates are located below four placement seats. Four limiting arms for restricting the downward rotation of the feeding plates are fixedly installed at equal intervals in a ring at the bottom of the rotating disk. Contact heads are fixedly installed in the middle of the bottom of each of the four feeding plates. A transmission ring seat is fixedly installed on the top of the worktable via three fixed seats, and the upper surface of the transmission ring seat is in contact with the contact head.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator loads the material through the placement seat on the side away from the heat-sealing head, thus avoiding accidental burns to the operator's hands during loading; at the same time, the servo motor drives the drive shaft to rotate inside the positioning bushing, and when the drive shaft rotates, it drives the placement seat to rotate through the rotating disk, thereby conveying the KN95 mask directly below the heat-sealing head.

[0010] Then, the electric push rod drives the hot-pressing head to move downwards. As the hot-pressing head moves downwards, it drives two limiting rods to move downwards along the inside of the two limiting sleeves, thus ensuring the stability of the hot-pressing head during downward movement. During the downward movement of the hot-pressing head, the KN95 mask undergoes hot-pressing edge sealing. Immediately afterwards, the servo motor continuously drives the rotating disk to rotate. When the rotating disk rotates the edge-sealed KN95 mask to the side near the collection bucket, the transmission ring seat has an opening on the side near the collection bucket. Under the action of gravity, the material feeding plate located at this point rotates downwards and opens, allowing the KN95 mask on top to slide and fall into the collection bucket automatically, thus achieving automatic material feeding and collection, avoiding the risk of burns from manual material handling. As the rotating disk continues to rotate, it drives the material feeding plate and the contact head to rotate. Through the cooperation of the transmission ring seat, the contact head can be pushed, causing the material feeding plate to rotate upwards and close, thus allowing for continued material feeding. This allows the mask sealing device to feed materials away from the hot-pressing head during use, and automatically collect materials after sealing, avoiding accidental burns to the operator's hands, providing excellent protection.

[0018] 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.

[0019] Depend on Figures 1 to 4The present invention includes a workbench 1, with support legs 2 fixedly installed at the four corners of the bottom of the workbench 1. An installation port 22 is opened on one side of the workbench 1, and a collection bucket 9 is installed inside the installation port 22. Both sides of the collection bucket 9 are fixedly connected to the workbench 1 through the cooperation of connecting pieces 21 and bolts. A support frame 3 is fixedly installed on one side of the top of the workbench 1. An electric push rod 4 is fixedly installed on the inner top of the support frame 3. A hot-pressed end cap 5 is fixedly installed on the transmission end of the electric push rod 4. A rotating disk 10 is provided above the middle of the workbench 1. Four placement seats 11 are fixedly installed in a ring at equal intervals on the upper side of the rotating disk 10. A servo motor 12 is fixedly installed in the middle of the bottom of the workbench 1. A transmission component is provided at the output end of the servo motor 12. The transmission component is connected to the rotating disk 10. The servo motor 12 outputs power to the rotating disk 10 through the transmission component, so that the rotating disk 10 rotates to feed materials. An automatic opening and closing mechanism is provided between the upper part of the workbench 1 and the lower part of the rotating disk 10 to open or close the placement seats 11.

[0020] Limiting rods 6 are fixed on both sides of the top of the hot-pressed head 5. Limiting sleeves 7 are fitted on the surface of the two limiting rods 6. Supporting rods 8 are fixedly installed on the surface of the two limiting sleeves 7. The tops of the two supporting rods 8 are fixedly connected to the top of the support frame 3.

[0021] During use, the operator loads the material through the placement seat 11 on the side away from the heat-sealing head 5 to avoid accidental burns to the operator's hands during loading; at the same time, the servo motor 12 is started to drive the rotating disk 10 and the placement seat 11 to rotate through the transmission component, thereby conveying the KN95 mask to the area directly below the heat-sealing head 5.

[0022] Then, the electric push rod 4 drives the hot-pressing head 5 to move down. When the hot-pressing head 5 moves down, it drives the two limiting rods 6 to move down along the inside of the two limiting sleeves 7, thereby ensuring the stability of the hot-pressing head 5 when it moves down. When the hot-pressing head 5 moves down, it will perform hot-pressing edge sealing processing on the KN95 mask.

[0023] Next, the servo motor 12 continues to drive the rotating disk 10 to rotate. When the rotating disk 10 drives the sealed KN95 mask to the side close to the collection bin 9, the KN95 mask slides down into the collection bin 9 through the automatic opening and closing mechanism to automatically collect the material, avoiding the risk of burns from manual material handling.

[0024] The transmission assembly includes a drive shaft 13, which is fixedly installed at the output end of the servo motor 12. The top end of the drive shaft 13 is fixedly connected to the middle of the bottom of the rotating disk 10. A positioning bushing 14 is rotatably mounted on the surface of the drive shaft 13. Three fixed legs 15 are fixedly mounted on the surface of the positioning bushing 14. The bottom ends of the three fixed legs 15 are all fixedly connected to the top of the worktable 1.

[0025] The automatic opening and closing mechanism includes four feeding plates 16. The four feeding plates 16 are rotatably mounted on the lower part of the rotating disk 10 via a rotating shaft, and the four feeding plates 16 are located below the four placement seats 11. Four limiting arms 17 are fixedly installed at equal intervals in a ring at the bottom of the rotating disk 10 to limit the downward rotation of the feeding plates 16. Contact heads 18 are fixedly installed in the middle of the bottom of each of the four feeding plates 16. A transmission ring seat 19 is fixedly installed on the top of the worktable 1 via three fixed seats 20. The upper surface of the transmission ring seat 19 is in contact with the contact head 18.

[0026] The servo motor 12 drives the drive shaft 13 to rotate inside the positioning sleeve 14. When the drive shaft 13 rotates, it drives the placement seat 11 to rotate through the rotating disk 10, thereby conveying the KN95 mask directly below the heat-sealing head 5.

[0027] When the servo motor 12 continuously drives the rotating disk 10 to rotate, when the rotating disk 10 drives the sealed KN95 mask to rotate to the side near the collection bucket 9, since the transmission ring seat 19 has an opening on the side near the collection bucket 9, the material feeding plate 16 located there will rotate downward and open under the action of gravity, so that the KN95 mask on it will slide down and fall into the collection bucket 9 to automatically collect the material, avoiding the risk of burns from manual material handling; when the rotating disk 10 continues to rotate, it will drive the material feeding plate 16 and the contact head 18 to rotate, and through the cooperation of the transmission ring seat 19, it can push the contact head 18, so that the material feeding plate 16 will rotate upward and close, so that the feeding can continue.
