Description

Technical Field

[0002] The present invention relates to a cleaning device, and more specifically, to a cleaning device for vacuum food packaging bags. Background Art

[0003] Food packed in vacuum bags is to put the product into a packaging container with high airtightness, and then evacuate the air inside the container to reach a predetermined vacuum state. In this way, the shelf life of food can be significantly extended, and the freshness and excellent taste of food can be maintained to the greatest extent.

[0004] After the vacuum bagged food completes the packaging process, it also needs to be sterilized. However, there is often oil stain remaining on the surface of the packaging bag after sterilization. Currently, the mainstream cleaning device in the market uses a bubble cleaning machine to improve the cleaning effect on the packaging bag by causing the cleaning liquid to tumble. Then, the packaging bag is sent to a vibrating drainer, and during continuous vibration, the excess water is quickly thrown off. Finally, the packaging bag enters a drying machine, and under the strong up and down air flow, its surface becomes dry and clean without any oil stain.

[0005] However, the existing cleaning machines have some defects that cannot be ignored in actual applications: On the one hand, during the cleaning process, in order to ensure that the bagged food can be completely covered by the liquid, a large amount of water needs to be injected. This not only results in a huge amount of water consumption for each cleaning, but also the cleaning time is relatively long, greatly affecting the overall production efficiency.

[0006] On the other hand, in order to improve the cleaning efficiency, surfactants, citric acid, sodium bicarbonate and other solvents are usually added to the clean water. These solvents mainly act on the scale, rust, specific chemical residues, grease and stubborn stains on the surface of the packaging bag. But in order to enhance the activity of the solvent, the temperature of the liquid must be increased and maintained throughout the cleaning process, which will undoubtedly consume a large amount of energy and increase the production cost. Summary of the Invention

[0007] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a cleaning device for vacuum food packaging bags, which can reduce energy loss, quickly raise the water level and maintain the temperature in the water.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Referring to Figures 1 to 5 As shown, to achieve the above object, the present invention provides the following technical solution: A vacuum food packaging bag cleaning device includes a mounting rack, a cleaning component, a drying component, and a conveying component. The conveying component is arranged on the mounting rack and is used to sequentially convey the packaging bags through the cleaning component and the drying component; The cleaning component includes a cleaning tank, in which a material distribution drum and an inflatable airbag are arranged. The material distribution drum is rotatably connected in the cleaning tank, and a plurality of ventilation holes are arranged on the material distribution drum. There is a driving structure between the inflatable airbag and the material distribution drum. When the inflatable airbag inflates and deflates, it respectively drives the material distribution drum to rotate; The drying component includes a drying chamber and a hot air blower. The hot air blower is used to convey hot air into the drying chamber. An air inlet pipe and an exhaust pipe are arranged between the drying chamber and the inflatable airbag, and an air inlet valve and an exhaust valve are respectively arranged on the air inlet pipe and the exhaust pipe.

[0023] The air extraction and exhaust structure is a prior art and will not be elaborated here.

[0024] In the design of the present invention, the device can quickly increase the liquid level height by the inflation of the inflatable airbag, thereby reducing the water volume requirement. And by using the heat of the drying chamber, it is conveyed into the inflatable airbag and then exchanges heat with the liquid in the cleaning tank to keep the liquid temperature, provide the activity of the solvent in the liquid, and improve the cleaning efficiency. During the above operation process, the water consumption can be reduced and the energy use efficiency can be improved.

[0025] The specific operation steps are as follows: 1. First, preheat the drying chamber, and input a certain amount of water and add a certain amount of cleaning agent into the cleaning tank; 2. Open the air inlet valve and the exhaust valve to make the drying chamber communicate with the inflatable airbag. The gas in the drying chamber enters the inflatable airbag through the circulating air pump. At this time, the inflatable airbag expands and heats up.

[0026] 3. When the temperature of the inflatable airbag is higher than the liquid temperature, heat conduction will occur, causing the liquid temperature to rise, thereby increasing the activity of the cleaning agent.

[0027] 4. When the inflatable airbag continuously expands, it will occupy the space of the cleaning tank, which can quickly raise the liquid level, facilitating the cleaning operation.

[0028] 5. When the inflatable airbag expands, the material distribution roller is rotated through the driving structure. At this time, the storage opening of the material distribution roller faces the conveying direction of the packaging bag. During the conveying process of the packaging bag, since there is no gas inside the vacuum packaging bag and its density is relatively large, it will sink to the bottom of the liquid. While for inferior products, there are gaps, and external air enters the packaging bag, causing the packaging bag to float above the liquid and move forward along the water flow and the conveying component. The inferior products will enter the material distribution roller, while the high-quality products will pass through the gaps and move towards the drying component direction.

[0029] 6. When the inflatable airbag contracts, the liquid level drops. At this time, the material distribution roller resets and pours out the inferior products along with the trend.

[0030] The present invention is further provided as follows: the roller body, the rotating shaft, and the torsion spring of the material distribution roller. The rotating shaft is fixedly connected to the mounting frame, and the roller body is rotationally connected to the rotating shaft through the torsion spring; When the inflatable airbag expands, the roller body is driven to rotate through the driving structure, and the torsion spring is compressed; When the inflatable airbag contracts, the torsion spring resets, thereby driving the roller body to reset and rotate; A gap for the packaging bag to pass through is left between the roller body and the bottom of the cleaning tank.

[0031] The design of this structure can meet the automatic reset process of step 6 above. When the inflatable airbag expands, the inflatable airbag will cause the roller body to rotate through the driving structure, and the torsion spring on the rotating shaft is compressed during the rotation of the roller body. When the inflatable airbag withdraws gas under the action of the circulating air pump, the restrictive force on the roller body is released. At this time, the roller body reversely resets under the action of the torsion spring.

[0032] The present invention is further provided as follows: the conveying component includes a conveyor belt and conveying plates. There are multiple groups of conveying plates, which are arranged at equal intervals along the conveying direction of the conveyor belt. The conveying component is used to push the packaging bag through the gap.

[0033] In order to improve the cleaning effect, a bubble cleaning machine can be set in the cleaning tank to make the liquid roll, thereby improving the cleaning effect. However, in order to separate inferior products and non-inferior products, the bubble cleaning machine needs to be installed behind the material distribution roller and started at intervals, which can ensure the separation of the front-end packaging bags and also ensure the separation of inferior products and non-inferior products during conveying.

[0034] The present invention is further provided as follows: the conveying plate includes a main body plate and a hinged plate. The main body plate is arranged in a "C" - shaped structure. The hinged plate is hinged to the middle of the main body plate, and a moving space for the main body plate to pass through is left between the roller body and the side wall of the mounting frame.

[0035] Such as Figure 5As shown, the design of the conveyor plate can completely push each batch of packaging bags forward, and clean the stains on them during the process of the packaging bags being soaked and colliding with each other.

[0036] And when the conveyor plate touches the roller body, the hinge plate will flip and avoid, so as to ensure the stable movement of the conveyor plate.

[0037] As Figure 2 shown, due to the large area of the conveyor plate, when putting the packaging bags, the operator needs to put them from the side in front of a conveyor plate.

[0038] The present invention is further arranged as: a storage cavity and a storage opening are arranged on the roller body, a material guiding bottom surface is arranged in the storage cavity, and when the inflatable airbag expands, the storage opening is directly opposite to the conveyor plate; When the inflatable airbag contracts, the packaging bags move out of the storage cavity along the material guiding bottom surface.

[0039] With the design of this structure, when the storage opening is directly opposite to the conveying direction of the packaging bags, the packaging bags can enter the storage cavity along with the storage opening, completing the material separation and storage operations during the cleaning process.

[0040] When the inflatable airbag contracts, the roller body rotates in reverse. At this time, the packaging bags can slide out along the material guiding bottom surface. Preferably, the rotation angle of the roller body is 90°. Thus, when receiving materials, the storage of the packaging bags is stable. And when discharging materials, they can slide out stably.

[0041] As Figure 3 shown, it is the state of receiving materials, the storage opening faces obliquely upward. At this time, the materials above can be stuck at the position of the storage opening, and with the extrusion of the conveyor plate, the liquid is poured into the packaging bags, and the density of the packaging bags increases and they fall, entering the storage cavity. Therefore, preferably, this structure is suitable for being placed near the position of discharging materials.

[0042] When in the state of discharging materials, the storage opening faces obliquely downward, and the liquid level drops. At this time, the materials slide out along with the storage opening, completing the collection of defective products. The operator only needs to check whether the defective products are soaked in water to quickly check whether they are defective products and quickly complete the quality inspection.

[0043] The present invention is further arranged as: the inflatable airbag includes an airbag frame and an airbag body. The airbag frame is arranged on one side of the roller body, an opening groove is arranged on the airbag frame, and the airbag body is installed in the airbag frame.

[0044] The present invention is further arranged as: the driving structure includes a driving gear, a driving rack and a driving plate. The driving gear is fixedly installed at one end of the roller body, the driving rack is meshed with the driving gear through a linkage gear, the driving plate is slidably connected in the airbag frame, and the airbag body is arranged on one side of the driving plate; The driving rack is installed on the driving plate.

[0045] The design of this structure, such as Figure 4 shown, when the airbag body expands, the drive plate moves downward. At this time, the drive rack is driven to move downward, the linkage gear rotates clockwise, and the drive gear rotates counterclockwise to complete the steering problem of the drum body.

[0046] When the airbag body contracts, under the action of the torsion spring, the drum body rotates clockwise, so that the drive plate moves upward through the linkage gear and the drive rack.

[0047] The present invention is further provided that: a storage rack is detachably connected to the upper end of the airbag frame. When the airbag body contracts and the liquid level drops, the packaging bag can fall into the storage rack, which is convenient for the staff to take away the storage rack and the packaging bag together.

[0048] The present invention is further provided that: multiple sets of material distribution drums and inflatable airbags are provided and arranged at equal intervals along the length direction of the cleaning tank. An inlet and an outlet are provided in the cleaning tank; An independent airbag is also provided in the cleaning tank, and the independent airbag is communicated with the drying chamber through a control valve.

[0049] The design of this independent airbag is preferably under the conveyor belt to improve space utilization.

[0050] When recycling inferior packaging bags, the independent airbag can be first controlled to contract to lower the liquid level. Then, the storage rack is placed on the airbag frame. Subsequently, the airbag body is controlled to contract and the drum body is rotated, and finally the packaging bag falls into the storage rack.

[0051] This independent airbag includes a remotely controlled control valve and a circulating air pump for air extraction and inflation.

[0052] The present invention is further provided that: the conveying component includes a lifting mechanism for conveying the packaging bags in the cleaning tank to the drying chamber; There is a material area left between the lifting mechanism and the conveyor belt, and an inclined plane is provided at the bottom of the material area.

[0053] With this structure design, the packaging bags that have completed the cleaning operation will accumulate on the side of the material area away from the conveyor belt along with the water flow and the inclined plane. At this time, the packaging bags move to the drying area along with the lifting mechanism.

[0054] In addition, in order to increase the temperature in the drying chamber, heat preservation curtains are designed at the inlet and outlet of the drying chamber to keep the temperature in the drying chamber as much as possible.

[0055] This lifting mechanism can be Figure 2 the structure shown, or other structures, which will not be elaborated here.

[0056] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
