[0002] Sealing machines for packaging bags are automated equipment used to heat-seal or press the edges of packaging bags. Their core function is to seal three sides or edges of materials such as plastic films and composite films through heating and pressurization processes, forming sealed packaging. This equipment uses a PLC control system, enabling precise adjustment of temperature, pressure, and speed. It is also equipped with automatic correction, photoelectric tracking, and static elimination functions to ensure stable and efficient sealing quality. Its applications are wide-ranging, covering food packaging, pharmaceutical moisture-proof sealing, leak-proof daily chemical products, anti-static treatment of electronic products, dustproof packaging of industrial parts, and sealing for express logistics. It is particularly suitable for product packaging requiring high cleanliness and high sealing performance, and is a key piece of equipment in modern packaging production lines for improving production efficiency and product safety.

[0003] The heat sealing strips on existing edge banding machines are usually exposed, and accidental contact by operators can cause burns, posing an operational risk. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a sealing machine for packaging bag production, which effectively solves the problem that the heat sealing strip on the existing sealing machine is usually exposed, and accidental contact by the operator can cause burns, which poses an operational risk.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing machine for packaging bag production, comprising a base, a support frame fixedly installed on the top of the base, 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 an upper protective box, a lower protective box fixedly installed on the inner top of the base, two support seats fixedly installed in the upper and lower parts of the interior of the upper and lower protective boxes, an upper hot pressing strip provided in the lower part of the interior of the upper protective box, a lower hot pressing strip provided in the upper part of the interior of the lower protective box, support arms fixedly installed on the sides of the lower and upper hot pressing strips that are far apart from each other, slide rods movably inserted at both ends of the two support arms, the two ends of the four slide rods respectively connected to the interior of the upper and lower protective boxes, a return spring sleeved on the surface of the four slide rods, the two ends of the four return springs respectively fixedly connected to the interior of the upper and lower protective boxes and the two ends of the two support arms, an elastic adjustment component provided on one side of the interior of the support frame, the elastic adjustment component being drivenly connected to the two support arms.

[0006] Preferably, the elastic adjustment component includes two rectangular sleeves, which are respectively disposed on one side of the upper protective box and the lower protective box. Both sides of the two rectangular sleeves are fixedly connected to the upper protective box and the lower protective box by fixing strips. Rectangular rods are inserted into the interior of the two rectangular sleeves. Push heads are fixedly installed at one end of the two rectangular rods. Telescopic springs are sleeved on the surface of the two rectangular rods. Both ends of the two telescopic springs are fixedly connected to the two push heads and the two rectangular sleeves, respectively.

[0007] Preferably, the ends of the two rectangular rods away from the push head extend into the interior of the upper and lower protective boxes respectively, and each is fixedly installed with a push block. One side of each push block is closely attached to an inclined block, and the sides of the two inclined blocks that are close to each other are fixedly connected to the two support arms respectively.

[0008] Preferably, the ends of the two push heads furthest from the rectangular rod are respectively attached to the first push strip and the second push strip. One side of the first push strip is fixedly connected to the inner top of the support frame through the first support rod, and the second push strip is fixedly connected to the upper protective box through the two second support rods.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator starts the electric push rod to drive the upper protective box to move down. When the upper protective box moves down, the second support rod drives the second pushing strip to move down, so that the first pushing strip and the second pushing strip can push the two pushing heads simultaneously. When the pushing heads are pushed, they drive the rectangular rod to move along the inside of the rectangular sleeve to the inside of the upper and lower protective boxes, and at the same time squeeze the two telescopic springs. The two telescopic springs enable the two rectangular rods to have the ability to elastically return to their original position. When the two rectangular rods move, the two pushing blocks push the two inclined blocks to move towards each other. When the two inclined blocks move towards each other, they will drive the two support arms to move towards each other.

[0010] When the two support arms move towards each other, they slide along the surfaces of the two slide bars and simultaneously compress the four return springs. This ensures the stability of the two support arms while giving them elastic return capability. When the two support arms move towards each other, they drive the upper and lower hot pressing strips to the outside of the upper and lower protective boxes. As the electric push rod continuously drives the upper protective box downward, the cooperation of the upper and lower hot pressing strips can heat-seal the packaging bag. This ensures that the upper and lower hot pressing strips are inside the upper and lower protective boxes before sealing, reducing operational risks. The hot pressing strips of this sealing machine are only exposed during the sealing operation, effectively preventing accidental burns to operators and greatly reducing operational risks.

[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 base 1, a support frame 2 fixedly mounted on the top of the base 1, an electric push rod 3 fixedly mounted on the top of the support frame 2, the transmission end of the electric push rod 3 extending downwards into the interior of the support frame 2 and fixedly mounted with an upper protective box 4, a lower protective box 5 fixedly mounted on the inner top of the base 1, and two support seats 22 fixedly mounted on the upper and lower parts of the interior of both the upper and lower protective boxes 4 and 5. An upper heat-pressing strip 6 is provided in the lower part of the interior of the upper protective box 4, and a lower heat-pressing strip 7 is provided in the upper part of the interior of the lower protective box 5. Support arms 10 are fixedly installed on the sides of strip 7 and upper hot pressing strip 6 that are far apart from each other. Slide rods 8 are movably inserted at both ends of the two support arms 10. The two ends of the four slide rods 8 are respectively connected to the interior of the upper protective box 4 and the lower protective box 5. Return springs 9 are sleeved on the surface of the four slide rods 8. The two ends of the four return springs 9 are respectively fixedly connected to the interior of the upper protective box 4 and the lower protective box 5 and the two ends of the two support arms 10. An elastic adjustment component is provided on one side inside the support frame 2. The elastic adjustment component is connected to the two support arms 10 in a transmission manner.

[0020] In use, the operator activates the electric push rod 3 to move the upper protective box 4 downwards. As the upper protective box 4 moves downwards, the elastic adjustment component drives the two support arms 10 to move towards each other. When the two support arms 10 move towards each other, they slide along the surfaces of the two slide rods 8 and simultaneously compress the four return springs 9. This ensures the stability of the movement of the two support arms 10 while giving them the ability to elastically return to their original position. When the two support arms 10 move towards each other, they drive the upper hot pressing strip 6 and the lower hot pressing strip 7 to move to the outside of the upper protective box 4 and the lower protective box 5. As the electric push rod 3 continues to drive the upper protective box 4 downwards, the cooperation of the upper hot pressing strip 6 and the lower hot pressing strip 7 can heat-seal the packaging bag. This ensures that the upper hot pressing strip 6 and the lower hot pressing strip 7 are inside the upper protective box 4 and the lower protective box 5 before sealing, reducing operational risks. The hot pressing strips of this sealing machine are only exposed during the sealing operation, which can effectively prevent accidental burns to the operator and greatly reduce operational risks.

[0021] The elastic adjustment assembly includes two rectangular sleeves 11, which are respectively disposed on one side of the upper protective box 4 and the lower protective box 5. Both sides of the two rectangular sleeves 11 are fixedly connected to the upper protective box 4 and the lower protective box 5 by fixing strips 12. A rectangular rod 13 is inserted into the inside of each of the two rectangular sleeves 11. A push head 14 is fixedly installed at one end of each of the two rectangular rods 13. A telescopic spring 15 is sleeved on the surface of each of the two rectangular rods 13. Both ends of the two telescopic springs 15 are fixedly connected to the two push heads 14 and the two rectangular sleeves 11, respectively.

[0022] Two rectangular rods 13 extend into the interior of the upper protective box 4 and the lower protective box 5 respectively, with push blocks 20 fixedly installed on each. One side of each push block 20 is closely attached to an inclined block 21. The sides of the two inclined blocks 21 that are close to each other are fixedly connected to two support arms 10 respectively. The ends of the two push heads 14 away from the rectangular rods 13 are closely attached to the first push strip 16 and the second push strip 19 respectively. One side of the first push strip 16 is fixedly connected to the inner top of the support frame 2 through the first support rod 17. The second push strip 19 is fixedly connected to the upper protective box 4 through two second support rods 18.

[0023] When the upper protective box 4 moves downward, the second support rod 18 drives the second pushing strip 19 to move downward, so that the first pushing strip 16 and the second pushing strip 19 can push the two pushing heads 14 simultaneously. When the pushing heads 14 are pushed, they drive the rectangular rods 13 to move along the inside of the rectangular sleeve 11 into the upper protective box 4 and the lower protective box 5, and at the same time squeeze the two telescopic springs 15. The two telescopic springs 15 enable the two rectangular rods 13 to have the ability to elastically return to their original position. While the two rectangular rods 13 are moving, the two pushing blocks 20 push the two inclined blocks 21 to move towards each other. When the two inclined blocks 21 move towards each other, they will drive the two support arms 10 to move towards each other.
