DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] Embodiment 1:

[0029] In one embodiment, Figure 1-Figure 8As shown, a vacuum packaging equipment includes a workbench 11 and a top cover 33. Fixed frames 22 are symmetrically fixed on the front and rear sides of the upper end of the workbench 11, and adjusting frames 26 are symmetrically fixed on the front and rear sides of the lower end of the top cover 33. A moving structure is arranged at the corner of the lower end of the workbench 11 for moving the equipment to a specified position. A transport structure is arranged inside the workbench 11 for transporting food bags. Limiting structures are symmetrically arranged at the opposite ends of the two fixed frames 22 for clamping the food bags. A sealing structure is arranged at the lower end of the top cover 33 for sealing the food bags. An adjusting structure is arranged at the upper end of the fixed frame 22, and the upper end of the adjusting structure is fixedly connected to the adjusting frame 26 for adjusting the height of the sealing structure according to the height of the food bag.

[0030] In this embodiment, the staff moves the equipment to the specified position through the mobile structure, and then uses the transportation structure to transport the food bag to the position of the limiting structure. The limiting structure clamps and limits the food bag, and adjusts the height of the sealing structure through the adjustment structure according to the height of the food bag. Then, the food bag is sealed through the sealing structure.

[0031] In one embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the movable structure includes four rotating columns 12, which are fixedly connected to the lower corners of the workbench 11. The lower ends of the rotating columns 12 are rotatably connected to the wheel cover 13, and the inside of the wheel cover 13 is rotatably connected to the roller 14. The upper end of the wheel cover 13 is installed with a first telescopic rod 15, and the telescopic end of the first telescopic rod 15 is fixedly connected to the limiting block 16.

[0032] The rollers 14 facilitate the workers to move and transport the equipment. When the equipment is moved to a designated position, the first telescopic rod 15 pushes the limiting block 16 downward so that the limiting block 16 is in close contact with the ground, thereby fixing the equipment at the designated position.

[0033] In one embodiment, Figure 3 and Figure 5 As shown, the transport structure includes a transport motor 18, which is installed on the left side of the front end of the workbench 11. The output end of the transport motor 18 extends to the inside of the workbench 11 and is fixedly connected to the active roller 19. The right side of the inside of the workbench 11 is rotatably connected to the auxiliary roller 20. The outer walls of the active roller 19 and the auxiliary roller 20 are movably connected with a transport belt 21.

[0034] The staff puts the food bag on the upper end of the conveyor belt 21, and drives the active roller 19 to rotate through the conveyor motor 18, and the active roller 19 drives the conveyor belt 21 to move, so as to transport the food bag to the limiting structure for limiting.

[0035] In one embodiment, Figure 1 and Figure 6As shown, the limiting structure includes two second telescopic rods 23, which are respectively installed on the outer walls of the two fixing frames 22 on the front and rear sides. The telescopic ends of the second telescopic rods 23 extend to the opposite end surfaces of the two fixing frames 22 and are fixedly connected to the limiting clamping plates 24.

[0036] When the food bag is transported to the position of the two limit clamps 24, the transport structure stops running, and the two second telescopic rods 23 simultaneously push the limit clamps 24 fixedly connected to their telescopic ends. The two limit clamps 24 clamp and limit the food bag, and then seal it through the sealing structure to prevent the food bag from tipping over during sealing and avoid a loose seal.

[0037] In one embodiment, Figure 6 , Figure 7 and Figure 8 As shown, the sealing structure includes a vacuum pump 30 and a fourth telescopic rod 27. The vacuum pump 30 is installed on the upper end of the top cover 33. The suction end of the vacuum pump 30 is fixedly connected to the suction piece 31. A plurality of suction pipes 32 are distributed in an array at the lower end of the suction piece 31. The fourth telescopic rod 27 is installed on the opposite end surfaces of the two adjustment frames 26. The telescopic end of the fourth telescopic rod 27 is fixedly connected to the fixed plate 28. The bottom of the fixed plate 28 away from the fourth telescopic rod 27 is fixedly connected to the heat sealing plate 29.

[0038] By running the vacuum pump 30, the air inside the food bag is extracted through the exhaust pipe 32. After the gas in the food bag is completely extracted, the fourth telescopic rod 27 is started to make the two symmetrically distributed heat-sealing pressing plates 29 seal the upper outer wall of the food bag, thereby completing the sealing work of the food bag.

[0039] In one embodiment, Figure 2 and Figure 6 As shown, the adjustment structure includes four third telescopic rods 25, which are installed at the upper corners of the fixed frame 22. The telescopic ends of the four third telescopic rods 25 correspond to the four corners of the lower end of the adjustment frame 26, and the telescopic ends of the third telescopic rods 25 are fixedly connected to the lower end of the adjustment frame 26.

[0040] The third telescopic rod 25 pushes the adjustment frame 26 to move up and down, thereby adjusting the sealing structure to a suitable height, so that the sealing structure can seal food bags of different sizes and heights, and has wide applicability.

[0041] Embodiment 2:

[0042] In one embodiment, Figure 1 , Figure 2 and Figure 3 As shown, handles 17 are fixedly installed at both the front and rear ends of the workbench 11.

[0043] The staff cooperates with the mobile structure through the handle 17 to push the device to move and control the moving direction of the device.

[0044] In one embodiment, Figure 4 As shown, the lower end of the limiting block 16 is provided with an anti-slip layer.

[0045] By providing an anti-skid layer at the lower end of the limiting block 16, the friction coefficient at the lower end of the limiting block 16 is increased, thereby increasing the friction between the limiting block 16 and the ground, ensuring that the device can be stably fixed at a designated position.

[0046] The above embodiment discloses a vacuum packaging device, in which the staff moves and transports the device through the handle 17 and the roller 14. When the device is moved to the specified position, the limiting block 16 is pushed downward by the first telescopic rod 15 so that the limiting block 16 is in close contact with the ground, thereby fixing the device at the specified position. The staff places the food bag on the upper end of the conveyor belt 21, and drives the active roller 19 to rotate through the conveyor motor 18. The active roller 19 drives the conveyor belt 21 to move, so that the food bag is transported to the position where the two limit clamps 24 are located. The transport motor 18 stops running, and the two first telescopic rods 15 are used to push the limiting block 16 downward. The two telescopic rods 23 simultaneously push the limiting clamps 24 fixedly connected to the telescopic ends thereof, and the two limiting clamps 24 clamp and limit the food bag. The third telescopic rod 25 pushes the adjusting frame 26 to move up and down, thereby adjusting the heat sealing plate 29 to a suitable height. By running the vacuum pump 30, the air inside the food bag is extracted through the exhaust pipe 32. After the gas in the food bag is completely extracted, the fourth telescopic rod 27 is started to make the two symmetrically distributed heat sealing plates 29 seal the upper outer wall of the food bag, thereby completing the sealing work of the food bag. Finally, the transport motor 18 is started to transport the packaged food bag out.

[0047] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
