Description

Technical Field

[0001] The invention belongs to the technical field of packaging equipment, and in particular relates to a vacuum-sealing integrated device for bagged materials and a sealing method. Background Art

[0002] During the production process, granular materials usually need to be vacuum packed. Vacuum packaging can form a closed environment, effectively isolating external pollutants such as dust and microorganisms to maintain the purity of the materials. In addition, the volume of the materials after vacuum packaging is reduced, making them easy to stack, store and transport, saving space, and not easy to break, which is convenient for logistics and warehousing management.

[0003] Before vacuum sealing, the material will be concentrated at the bottom of the packaging bag due to its own gravity. The existing equipment will directly perform vacuum sealing, which will cause the sides of the bagged material to be curved, making it inconvenient to stack and store. Summary of the invention

[0008] The initial position of the lifting plate is above the placement platform. When the bagged material is placed on the lifting plate, it will be pushed toward the placement platform. The linkage assembly drives the rack to move, and through the engagement with the gear, the leveling plate is driven from the initial lying state to the side close to the bagged material, thereby squeezing and leveling it.

[0018] The sealing method of the integrated device for vacuuming and sealing bagged materials according to any one of the above items comprises the following steps:

[0019] S1. Leveling of bagged materials:

[0020] Place the unsealed bagged material on the lifting plate, which will fall into the groove of the placement platform.

[0035] It should be noted that the leveling plate 412 is also threadedly connected to a threaded rod, one end of which is fixedly and rotatably connected to a clamp, and the clamp is fixedly connected to a movable sleeve provided on a guide rod of the leveling plate 412, which is used to prevent the leveling plate 412 from rotating when the threaded rod is rotated, but to push the leveling plate 412 towards or away from the bagged material, so as to adapt to bagged materials of different sizes and specifications and level them.

[0036] Specifically, the initial position of the lifting plate 47 is above the placement platform 41. When the bagged material is placed on the lifting plate 47, it will be pushed toward the placement platform 41. The linkage assembly drives the rack 410 to move, and through the engagement with the gear 413, the leveling plate 412 is driven from the initial lying state to the side close to the bagged material, thereby squeezing and leveling it.

[0037] like Figure 2 and Figure 3 As shown, the pushing assembly includes a telescopic rod 46, which is fixedly connected to a lifting plate 47, a groove whose shape and size are matched with the lifting plate 47 is opened on the placement platform 41, a through opening is opened on the side of the groove close to the pushing assembly, a spring 45 is fixedly connected to one side of the lifting plate 47, and one end of the spring 45 away from the lifting plate 47 is fixedly connected to a fixing seat 43, the fixing seat 43 is fixedly connected to the placement platform 41, and one end of the telescopic rod 46 away from the lifting plate 47 is fixedly connected to the fixing seat 43.

[0038] Specifically, through the force of the spring 45, when there is no object above the lifting plate 47, the lifting plate 47 will be pushed away from the groove of the placement platform 41, and at the same time, the leveling plates 412 on both sides of the placement platform 41 are also in a laid-down state. When the bagged material is placed above the lifting plate 47, it will be pressed into the groove due to gravity. At this time, the linkage component will pull the rack 410 to move, and through the engagement with the gear 413, the laid-down leveling plate 412 is driven to flip toward the bagged material.

[0039] like Figure 2 and Figure 3As shown, a cylinder 44 is provided on the inner wall of the fixing seat 43 , and a pad is fixedly connected to the output end of the cylinder 44 , and the pad is located directly below the lifting plate 47 .

[0040] Specifically, the cylinder 44 can push the bagged materials placed on the lifting plate 47 to rise, and the linkage assembly can drive the rack 410 to move, thereby driving the leveling plate 412 to fall down, so as to facilitate pushing the bagged materials to the working area of ​​the vacuum sealing machine 10.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, the linkage assembly includes a connecting rod 48, which is hinged to the lifting plate 47, and the placement platform 41 is provided with a sliding opening with a shape and size matching the connecting rod 48.

[0043] Specifically, through the sliding cooperation between the guide block and the guide groove, the connecting rod 2 49 can only move linearly toward the direction approaching the lifting plate 47 or away from the lifting plate 47 .

[0044] like Figure 2 and Figure 5 As shown, the lifting mechanism 30 includes a lifting plate 31, a lifting arm 33 is fixedly connected to the side wall of the lifting plate 31, a sliding sleeve 42 is fixedly connected to one side of the placement platform 41, the sliding sleeve 42 is movably mounted on the outer ring of the lifting arm 33, and a removable anti-slip baffle 34 is installed at the end of the lifting arm 33 away from the lifting plate 31.

[0045] Specifically, a ball bearing may be provided between the lifting arm 33 and the second sliding sleeve 42 to reduce friction, so as to facilitate the placement platform 41 to slide above the lifting arm 33 and push the bagged material away from or close to the vacuum sealing machine 10 .

At the same time, the lifting plate 31 is slidably connected to the column of the vacuum sealing machine 10 through a sliding sleeve 32, which is used to prevent the lifting plate 31 from rotating with the screw rod 20, so that when the screw rod 20 rotates, the lifting plate 31 will drive the placement platform 41 to rise and fall through the lifting arm 33.

[0048] The sealing method of the integrated device for vacuum sealing of bagged materials comprises the following steps:

[0049] S1. Leveling of bagged materials:

[0050] The unsealed bagged material is placed on the lifting plate 47, and the lifting plate 47 will fall into the groove of the placing platform 41.
