Technical Field

[0001] The utility model belongs to the field of vacuum pumping devices, and in particular relates to a single-bag vacuum pumping device. Background Art

[0002] At present, after the materials are packaged in valve bags, they are generally transported to the palletizing station via a conveyor belt. Robots grab the bags one by one and stack them on pallets. Finally, they are picked up by forklifts and loaded onto trucks for shipment.

[0003] However, in the actual packaging process, when the material is packaged in a valve bag, some gas is easily mixed into the material and enters the valve bag. Due to the presence of gas, not only will the material composition change, but also the valve bag will be in a bulging state. When the robot is stacking (5-10 layers are required), the overall height of the stacking will increase, exceeding the stacking requirements, affecting subsequent transportation and delivery, and also increasing the risk of the entire stack collapsing. Therefore, it is urgent to design a device that can vacuum the material after packaging. Summary of the invention

[0004] In order to overcome the defects of the prior art, the purpose of the utility model is to provide a new single-bag vacuum pumping device.

[0007] According to a specific implementation and preferred aspect of the utility model, the vacuum box includes an upper box body and a lower box body arranged up and down, and a driving component for driving the upper box body and the lower box body to move relatively close or away. When the vacuum chamber is open, the upper box body and the lower box body are separated from each other up and down, and a single package of materials is horizontally transported between the upper box body and the lower box body; when the vacuum chamber is sealed, the upper box body and the lower box body are sealed and connected up and down. Here, a single package of materials can be vacuumed through the vacuum box during horizontal transmission. Therefore, the vacuum extraction device of the present application can be flexibly incorporated into the material packaging production line to realize continuous packaging-vacuum extraction-palletizing-loading operations of materials, which is convenient for realizing high automation operations and improving production efficiency.

[0008] Preferably, the lower box is fixedly connected to the frame, and the driving component includes a lifting cylinder connected to the upper box.

[0009] Preferably, the vacuum box also includes a connecting rod assembly connected between the upper box body and the frame, and when the lifting cylinder drives the upper box body to move up and down, the connecting rod assembly drives the upper box body to remain horizontal. Here, the upper box body is ensured to move up and down smoothly, and the upper and lower boxes are accurately connected to form a seal.

[0010] Specifically, the connecting rod assembly includes a plurality of upper connecting rods spaced side by side, lower connecting rods corresponding to the plurality of upper connecting rods, and a synchronous rod, wherein the upper end of each upper connecting rod is rotatably connected to the frame, the lower end of each lower connecting rod is rotatably connected to the top surface of the upper box body, and the lower end of each upper connecting rod is rotatably connected to the upper end of the corresponding lower connecting rod through a pivot, and the synchronous rod is rotatably connected to the plurality of pivots.

Here, the automatic input and output of the packaging bag is realized.

[0013] According to another specific implementation and preferred aspect of the utility model, the shaping module is fixedly arranged in the upper box body, and the shaping module forms a shaping surface from the bottom surface. Here, as the upper and lower boxes move toward each other, the shaping module can gradually squeeze the packaging bag to implement preliminary exhaust.

[0014] Preferably, a plurality of vents are formed on the shaping module and are arranged to pass through from top to bottom, thereby ensuring that the upper surface of the packaging bag can also be vented normally, thereby improving the venting efficiency.

[0030] like Figures 1 to 3 As shown, the single bag vacuuming device involved in this embodiment includes a frame 1, a vacuum box 2 with a vacuum cavity, a vacuuming component connected to the vacuum cavity, and a shaping module 3 arranged in the vacuum cavity. The valve bag material used for the material packaging of this embodiment is a breathable material, which can be any material with a breathability of 40%-60% in the prior art.

[0031] Specifically, the vacuum box 2 can be opened or closed to drive the vacuum chamber to be open or sealed, that is, when the vacuum chamber is open, a single package of material A can be sent into the vacuum chamber or taken out of the vacuum chamber; when the vacuum chamber is sealed, vacuum can be evacuated.

[0032] The vacuum box 2 includes an upper box body 20 and a lower box body 21 arranged vertically, and a driving component 22 for driving the upper box body 20 and the lower box body 21 to move relatively closer or farther away. When the vacuum chamber is open, the upper box body 20 and the lower box body 21 are separated from each other vertically, and a single package of material is horizontally transported between the upper box body 20 and the lower box body 21; when the vacuum chamber is sealed, the upper box body 20 and the lower box body 21 are sealed and connected vertically.

[0033] In some specific embodiments, the upper box body 20 can be movably arranged up and down, and the lower box body 21 is fixedly connected to the frame 1; the driving component 22 includes a lifting cylinder 220 connected to the upper box body 20, and the upper box body 20 is driven to move up and down by the lifting cylinder 220; at the same time, when the upper box body 20 rises to the highest position, a nylon slider is set between the side wall of the upper box body 20 and the frame 1 to form a limit, thereby improving safety.

[0034] For the convenience of implementation, the vacuum box 2 also includes a connecting rod assembly 23 connected between the upper box body 20 and the frame 1, and a plurality of transmission rollers 24 rotatably connected to the lower box body 21 and distributed side by side and at intervals along the feeding direction of a single bag of material. When the lifting cylinder 220 drives the upper box body 20 to move up and down, the connecting rod assembly 23 drives the upper box body 20 to remain horizontal.

[0035] In some specific embodiments, there are two groups of connecting rod assemblies 23 and they are arranged side by side in a width direction or a length direction of the upper box body; each group of connecting rod assemblies 23 includes a plurality of upper connecting rods 230 arranged side by side in a spaced manner, a lower connecting rod 231 corresponding to the plurality of upper connecting rods 230, and a synchronization rod 232, wherein the upper end of each upper connecting rod 230 is rotationally connected to the frame 1, the lower end of each lower connecting rod 231 is rotationally connected to the top surface of the upper box body 20, and the lower end of each upper connecting rod 230 is rotationally connected to the upper end of the corresponding lower connecting rod 231 through a pivot, and the synchronization rod 232 is synchronously rotationally connected to the plurality of pivots. In other words, each upper connecting rod 230 forms a crank structure with the corresponding lower connecting rod 231, and under the linkage of the synchronization rod 232, the upper box body 20 is kept in a horizontal state.

[0036] At the same time, with the cooperation of the external transmission line, the single package of materials is horizontally transmitted from the outside to the inside to the multiple transmission rollers 24, or the multiple transmission rollers 24 output the single package of materials horizontally from the inside to the outside.

[0037] In this example, a negative pressure port k1 is formed at the top of the upper box body 20, and an exhaust port k2 is formed at the bottom of the lower box body 21. The vacuum pumping component adopts conventional technology and is connected to the negative pressure port k1. When the vacuum chamber is sealed, the vacuum pumping component removes the air in the vacuum chamber and forms a vacuum; a sealing gasket d and a power component j connected to the sealing gasket d are provided at the exhaust port k2, wherein the power component j drives the sealing gasket d to open or seal the exhaust port k2.

[0038] In order to further facilitate implementation, a regulating port k3 for adjusting the negative pressure value is also formed at the bottom of the lower box body 21.

[0039] That is to say, when the vacuum pumping component draws vacuum through the negative pressure port k1, the sealing gasket d seals the exhaust port k2, and adjusts the negative pressure amount and time by adjusting the size of the adjustment port k3; after a single package of material is exhausted, the sealing gasket d opens the exhaust port k2, allowing outside air to enter the vacuum box 2 to restore the air pressure in the box, and open the upper and lower boxes.

[0040] In this example, the shaping module 3 is fixedly arranged in the upper box body 20, and the shaping module 3 forms a shaping surface m from the bottom surface that can cover the front side (ie, the upper surface) of the material valve bag, and the shaping surface m simultaneously flattens the front side of the material valve bag.

[0041] Specifically, the shaping module 3 adopts a horizontally arranged mesh plate, and a plurality of vents k4 are formed on the shaping module 3 and are arranged to penetrate vertically.

[0042] In summary, after adopting the vacuum pumping device, first open the vacuum box to open the vacuum cavity, and place the material packaged with breathable material in the vacuum cavity; then close the vacuum box to drive the vacuum cavity to seal, and use the vacuum pumping component to extract the air in the vacuum cavity to form a vacuum, and then use the shaping surface on the shaping module to simultaneously flatten the front and / or back of the packaging bag to discharge the gas in the material. Therefore, compared with the prior art, the utility model, on the one hand, places a single package of material packaged with breathable material in the vacuum cavity, and discharges the gas in the valve bag under vacuum, thereby ensuring that the material composition meets the shipping requirements; on the other hand, with the cooperation of the shaping module, the surface of the valve bag is ensured to be flat, so that the surrounding and upper surfaces of the stack stacked by the robot remain flat, and the risk of the whole stack collapsing during transportation and delivery is reduced; thirdly, a single package of material can be vacuumed through the vacuum box during horizontal transmission. Therefore, the vacuum pumping device of the present application can be flexibly incorporated into the material packaging production line to achieve continuous material delivery. The packaging - vacuuming - palletizing - loading operations are carried out to facilitate high-automatic operations and improve production efficiency; fourthly, by setting a connecting rod assembly, the upper box body can be guaranteed to move up and down smoothly, and the upper and lower boxes can be accurately docked to form a seal; fifthly, with the mutual movement of the upper and lower boxes, the shaping module can gradually squeeze the packaging bag to implement preliminary exhaust. At the same time, through the vents on the shaping module, it is ensured that the upper surface of the packaging bag can also be exhausted normally, thereby improving the exhaust efficiency; sixthly, by setting a transmission roller, the automatic input and output of the packaging bag can be realized; seventhly, the structure is simple and easy to install and implement.

[0043] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
