[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figures 1-3 As shown, a food packaging sealing device includes a body 1, a sterilization lamp strip 2, a nitrogen generator 3, and a collection box 4. The sterilization lamp strip 2 for sterilization is bolted to the upper part of the inner wall of the body 1. The nitrogen generator 3 for gas filling is connected through the upper part of the inner wall of the body 1 near the sterilization lamp strip 2. The collection box 4 for collecting food is slidably connected through one side of the inner wall of the body 1. Cooling fans 7 for cooling the packaging are connected through the front and rear parts of the inner wall of the body 1. The body 1 is also equipped with a conveying mechanism 5 for feeding and a sealing mechanism 6 for sealing.

[0030] The conveying mechanism 5 includes a conveying roller z501 placed inside the machine body 1. The conveying roller z501 is used to support the conveyor belt z502. The conveyor belt z502 for guiding food is sleeved on the outside of the conveying roller z501.

[0031] In this embodiment, the door on one side of the machine body 1 is opened, and the food to be packaged is placed on the conveyor belt y505 for conveying. During the conveying process, the sterilization lamp strip 2 irradiates the packaged food in the conveying process to sterilize it. Then, the nitrogen generator 3 injects nitrogen into the packaged food. The two sets of heat sealing strips 609 are pressed against each other on the packaging bag of the packaged food to seal it. When the sealed packaged food passes through the cooling fan 7, it is quickly cooled by the cold air blown out by the cooling fan 7.

[0032] The surface of the conveyor roller z501 has raised retaining rings to prevent the conveyor belt z502 from falling off the conveyor roller z501. The conveyor belt z502 moves synchronously with the conveyor belt y505 to prevent the packaged food from tilting back and forth when the conveyor belt y505 moves the packaged food. Another set of conveyor rollers z501 is rotatably connected to the bottom of the cross frame 513 through a bracket, and the other set of conveyor rollers z501 can be slightly adjusted to both sides to tension the conveyor belt z502. The motors used in this solution are all servo motors and are controlled by a servo controller.

[0033] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the front of the machine body 1 is connected to a conveyor motor 503 for driving the conveyor roller y504 to rotate via a motor base. The output end of the conveyor motor 503 passes through the inner wall of the machine body 1 and is connected to the conveyor roller y504 via a coupling. The conveyor roller y504 passes through and is rotatably connected to the inner wall of the machine body 1, and a conveyor belt y505 for conveying food is sleeved on the outer side of the conveyor roller y504.

[0034] The conveyor motor 503 drives the conveyor roller y504 to rotate, and the conveyor roller y504 drives the conveyor belt y505 to move, conveying the packaged food. The conveyor belt y505 is tensioned by a tensioning wheel.

[0035] In one embodiment, such as Figure 3 and Figure 4 As shown, the rear part of the conveying roller y504 is bolted to a synchronous pulley a506. The outer side of the synchronous pulley a506 is meshed with a synchronous belt 507. The synchronous belt 507 is also meshed with a synchronous pulley b508. The synchronous pulley a506, the synchronous belt 507 and the synchronous pulley b508 are used to transmit power. The front part of the synchronous pulley b508 is bolted to an outer patterned roller 509. The outer patterned roller 509 passes through and is rotatably connected to the inner wall of the machine body 1.

[0036] When the conveyor roller y504 rotates, the conveyor roller y504 drives the synchronous pulley a506 to rotate. The synchronous pulley a506 drives the synchronous pulley b508 and the outer pattern roller 509 to rotate via the synchronous belt 507, so that the outer pattern roller 509 rotates together with the conveyor roller y504.

[0037] In one embodiment, such as Figure 4 and Figure 5As shown, the outer side of the outer roller 509 is provided with a housing 510 for mounting components. A bevel gear a511 for transmission is connected through a bearing on the inner wall of the housing 510. A bevel gear b512 for transmission is meshed below the bevel gear a511. The bevel gear b512 is connected through a bearing on the inner wall of the housing 510 and is bolted to the top of the conveyor roller z501.

[0038] When the outer roller 509 rotates, it drives the bevel gear a511 to rotate, the bevel gear a511 drives the bevel gear b512 to rotate, and the bevel gear b512 drives the conveyor roller z501 to rotate, so that the conveyor roller z501 and the conveyor roller y504 rotate together, thereby allowing the conveyor belt z502 and the conveyor belt y505 to move synchronously. This prevents the packaged food from tipping over due to friction when the two sets of conveyor belts z502 limit the packaged food.

[0039] In one embodiment, such as Figure 1 and Figure 4 As shown, the upper surface of the outer casing 510 is bolted to a crossbeam 513 for moving the outer casing 510. The crossbeam 513 abuts against the inner wall of the machine body 1. A guide rod 514 passes through and slides through the crossbeam 513 via a linear bearing. The guide rod 514 is bolted to the inner wall of the machine body 1. A bidirectional threaded rod 515 for moving the crossbeam 513 is threaded to the crossbeam 513 away from the guide rod 514. The bidirectional threaded rod 515 passes through and is connected to the inner wall of the machine body 1 via a bearing. The front part of the bidirectional threaded rod 515 is connected to an adjusting motor 516 for rotating the bidirectional threaded rod 515 via a coupling. The adjusting motor 516 is connected to the front part of the machine body 1 via a motor mount.

[0040] By starting the adjusting motor 516, the bidirectional threaded rod 515 is driven to rotate. The bidirectional threaded rod 515 drives the two sets of crossbars 513 to slide in opposite directions along the slide bar 514, thereby driving the two sets of outer shells 510, bevel gear a511, bevel gear b512, conveyor roller z501 and conveyor belt z502 to move in opposite directions, thereby adjusting the distance between the two sets of conveyor belts z502 and limiting the packaging of different specifications of food.

[0041] In one embodiment, such as Figures 1-3 and Figure 6As shown, the sealing mechanism 6 includes a sliding groove 601 opened at the front and rear of the inner wall of the machine body 1. A drive motor 602 for driving the lead screw 603 to rotate is connected to the upper part of the inner wall of the sliding groove 601 via a motor base. The output end of the drive motor 602 is connected to the lead screw 603 for driving the support frame 604 to slide via a coupling. The other end of the lead screw 603 is connected to the inner wall of the sliding groove 601 via a bearing, and the outer side of the lead screw 603 is threadedly connected to the support frame 604 for installing parts.

[0042] The drive motor 602 is started, which drives the lead screw 603 to rotate on the inner wall of the slide 601. The lead screw 603 drives the support frame 604 to slide up and down in the slide 601, adjusting the height of the heat sealing strip 609 to seal packaged food of different heights.

[0043] In one embodiment, such as Figure 6 and Figure 7 As shown, one side of the support frame 604 is connected to a cylinder 605 for sliding the toothed plate a606 via a bracket. The output end of the cylinder 605 is connected to the toothed plate a606 for moving the heat sealing strip 609 via bolts. The toothed plate a606 is slidably connected to the inner wall of the support frame 604.

[0044] A through slot is provided on one side of the support frame 604 for the toothed plate a606 to pass through. When the cylinder 605 extends or retracts, it drives the toothed plate a606 to slide within the support frame 604.

[0045] In one embodiment, such as Figure 7 As shown, a spur gear 607 is meshed with one side of the toothed plate a606 to drive the toothed plate b608 to slide. The spur gear 607 is connected to the upper part of the inner wall of the support frame 604 through a bearing, and a toothed plate b608 is meshed with one side of the spur gear 607. The toothed plate b608 is slidably connected to the inner wall of the support frame 604. Both the toothed plate a606 and the toothed plate b608 are connected to a heat sealing strip 609 for sealing through a bracket below them.

[0046] When the toothed plate a606 slides, it drives the spur gear 607 to rotate. The spur gear 607 drives another set of toothed plates b608 to slide in the opposite direction, thereby driving the two sets of heat sealing strips 609 to slide in the opposite direction.

[0047] The above embodiment discloses a food packaging sealing device. First, the cylinder 605 is shortened to move the two sets of heat-sealing strips 609 away from each other. Based on the specifications of the packaged food, the adjusting motor 516 is activated to adjust the distance between the two sets of conveyor belts z502. The drive motor 602 is activated to adjust the height of the two sets of heat-sealing strips 609. Then, the conveyor motor 503 is activated to move the conveyor belt y505 and the conveyor belt z502 together. The door on one side of the machine body 1 is opened, and the packaged food to be sealed is placed on the conveyor belt y505. After sterilization and nitrogen filling, it is detected by a proximity sensor. The cylinder 605 is then extended, causing the two sets of heat-sealing strips 609 to move closer together, pressing against the packaged food for sealing. After sealing, the heat-sealing strips 609 are reset. Then, the packaged food is rapidly cooled by the cold air blown out by the cooling fan 7 and falls into the collection box 4. The collection box 4 is then pulled out, and the sealed packaged food is removed for the next step.

[0048] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
