Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging technology, and in particular to a vacuum packaging machine for sheet materials. Background Technology

[0002] Vacuum packaging machines for sheet materials are specially designed for sheet, plate, and film materials (such as sliced ​​meat, leather, and thin metal sheets). Their core function is to achieve moisture protection, oxidation prevention, extended shelf life, and convenient storage and transportation of sheet materials through vacuuming and sealing processes.

[0003] When vacuum packaging sheet materials, it is difficult to achieve a tight fit after the sheet materials are dropped in. At this time, the gas inside the packaging bag will be trapped between the sheet materials. If the gas is not discharged in time, it will be difficult to meet the requirement of vacuum packaging to compress the volume as much as possible. The trapped gas can also cause damage to the sheet materials (oxidation, deterioration, mold and rust, etc.). Therefore, it is very necessary to study a vacuum packaging machine for sheet materials. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that sheet materials are difficult to tightly adhere after being fed into the packaging bag. At this time, the gas inside the packaging bag will be trapped between the sheet materials. If the gas is not discharged in time, it is difficult to meet the requirement of vacuum packaging to compress the volume as much as possible. The trapped gas can also cause damage to the sheet materials (oxidation, deterioration, mold and rust, etc.). Therefore, a sheet material vacuum packaging machine is proposed.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A vacuum packaging machine for sheet materials includes a packing table body, a material bag for vacuum packaging is provided in the middle of the packing table body, a discharge pipe of the vacuum packaging machine is provided at the rear end of the packing table body, and air bags for intermittently discharging residual gas from the material bag are provided on both sides inside the packing table body.

[0007] Furthermore, a miniature air pump is installed on one side of the packaging platform body, and an air distribution pipe is fixed to the output end of the miniature air pump. A flexible hose is connected between the air bag and the input end of the air distribution pipe. A control component is also installed on the air distribution pipe. The control component is an electromagnetic reversing valve, which is installed on the side close to the miniature air pump.

[0008] Furthermore, there are four airbags on each side, and the four airbags are arranged in a rectangular shape. The initial installation positions of the four airbags on the same side are all on the same vertical plane.

[0009] This utility model has the following beneficial effects:

[0010] 1. This product is used to intermittently tap the material bag with an air bladder when packaging sheet materials, thereby timely expelling the residual gas inside the material bag, which effectively ensures the maximum compression volume required for vacuum packaging, while also preventing the phenomenon of residual gas damaging the sheet materials.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example:

[0016] A vacuum packaging machine for sheet materials includes a packaging table body 1. The packaging table body 1 is made of 304 stainless steel, which meets the requirements of food-grade / industrial-grade corrosion resistance. The overall structure is rectangular, and the flatness error of the table surface is ≤0.5mm to ensure that the material bag 2 is placed stably. The material bag 2 for vacuum packaging is set in the middle of the packaging table body 1. The discharge pipe 3 of the vacuum packaging machine is set at the rear end of the packaging table body 1. Airbags 4 are set on both sides inside the packaging table body 1 to intermittently discharge the residual gas of the material bag 2.

[0017] A miniature air pump 5 is installed on one side of the packaging table body 1. The miniature air pump 5 is a DC 12V / 24V miniature piston air pump with a displacement of 1-2L / min and a maximum air pressure of 0.8MPa. It is fixed to the mounting bracket on one side of the packaging table body 1 by bolts. An air filter with a filtration accuracy of 5μm is installed at its air inlet end to prevent dust from entering the air pump and affecting its lifespan. A distribution pipe 6 is fixed at the output end of the miniature air pump 5. A flexible hose 7 is connected between the air bladder 4 and the input end of the distribution pipe 6. A control component is also installed on the distribution pipe 6. The control component is an electromagnetic reversing valve 8. The electromagnetic reversing valve 8 is installed on the side close to the miniature air pump 5 to realize the synchronous control of the expansion and contraction of all air bladders 4. The electromagnetic reversing valve 8 is a two-position three-way electromagnetic reversing valve with the same working voltage as the miniature air pump and a diameter of 6mm. It is installed in series at the end of the distribution pipe 6 close to the miniature air pump 5. Its control end is connected to the main control circuit board of the packaging machine (not shown in the diagram) through a wire to switch the air path on / off and direction.

[0018] Four airbags 4 are provided on each side. The airbags 4 are embedded inside the packaging table body 1 on both sides, with four on each side. The four airbags 4 on the same side are distributed in a 2×2 rectangular shape. The distance between adjacent airbags 4 is 30-50mm, which is suitable for packaging bags of sheet materials with a width of 100-300mm. The initial installation surfaces of the four airbags 4 on the same side are all on the same vertical plane with an error of ≤0.2mm, which ensures that the material bag 2 can be uniformly squeezed on both sides when inflated. The airbags 4 are made of aging-resistant silicone with a thickness of 2-3mm and a maximum expansion thickness of 15mm. The surface is smooth and without protrusions to avoid scratching the material bag 2.

[0019] During operation, the material bag 2 is first placed on the discharge pipe 3 and fixed. At this time, the vacuum packaging machine draws a vacuum while feeding the material. The sheet material falls into the packaging. At this time, the micro air pump 5 and the electromagnetic reversing valve 8 work together to realize the intermittent expansion and contraction of the eight air bags 4, thereby sending out the gas remaining in the material bag 2 from the discharge pipe 3, thus ensuring that the sheet material is packaged and compressed more fully and smoothly.

[0020] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
