Description

Technical Field

[0001] This utility model relates to a cleaning device, and more specifically, to a packaging bag cleaning and drying device. Background Technology

[0002] Packaging bags play a crucial role in the material packaging process. For certain products, the packaging bags often require sterilization after the packaging process is complete. Taking food vacuum packaging as an example, oil residue often remains on the surface of the packaging bags after sterilization. Therefore, it is necessary to clean and dry the packaging bags before they enter the transportation and transfer process.

[0003] Currently, the mainstream cleaning equipment on the market uses bubble washing machines, which improve the cleaning effect on packaging bags by causing the cleaning solution to tumble. However, existing washing machines have some significant drawbacks in practical applications:

[0004] Firstly, during the cleaning process, a large amount of water needs to be injected to ensure that the packaged food is completely submerged in the liquid. This not only results in a high water consumption for each cleaning, but also a longer cleaning time, which affects the overall cleaning efficiency.

[0005] Secondly, to improve cleaning efficiency, solvents such as surfactants, citric acid, and sodium bicarbonate are usually added to the water. These solvents are mainly effective against scale, rust, specific chemical residues, grease, and stubborn stains on the surface of the packaging bags. However, to enhance the activity of the solvents, the temperature of the liquid needs to be increased and maintained throughout the cleaning process, which undoubtedly consumes a lot of energy. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a packaging bag cleaning and drying device that can quickly raise the water level and reduce the energy loss of heat preservation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a packaging bag cleaning and drying device, comprising a cleaning tank, a conveying component, and a drying component, wherein the conveying component is used to sequentially convey the packaging bags through the cleaning tank and the drying component, and an inflatable air bladder is provided in the cleaning tank;

[0008] The drying assembly includes a drying chamber and a hot air blower, and the inlet and outlet ends of the drying chamber are equipped with flexible sealing curtains.

[0009] An air supply assembly is provided between the inflatable airbag and the drying chamber.

[0010] The present invention is further configured such that: an airbag frame is provided in the cleaning tank, the inflatable airbag is installed in the airbag frame, and a conveying gap is left between the airbag frame and the bottom of the cleaning tank for the packaging bag to pass through.

[0011] The present invention is further configured such that: the conveying assembly includes a conveyor belt and a conveyor plate, the conveyor plate is provided in multiple sets and is arranged at equal intervals along the conveying direction of the conveyor belt, and the conveyor plate moves through the conveying gap during the conveying process of the conveyor belt.

[0012] The present invention is further configured such that: multiple sets of airbag frames and inflatable airbags are provided and are arranged at equal intervals along the length of the cleaning tank.

[0013] The present invention is further configured such that: the air supply component includes an air inlet pipe, an air outlet pipe, an air inlet valve, an air outlet valve, and an air pump; the expansion airbag is connected to the drying chamber through the air inlet pipe and the air outlet pipe respectively.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] Reference Figures 1 to 3 As shown, in order to achieve the above objectives, the present invention provides the following technical solution: a packaging bag cleaning and drying device, including a cleaning tank 1, a conveying component 2, and a drying component 3. The conveying component 2 is used to convey the packaging bags sequentially through the cleaning tank 1 and the drying component 3. An inflatable airbag 4 is provided in the cleaning tank 1.

[0025] The drying assembly 3 includes a drying chamber 31 and a hot air blower 32. Both the inlet and outlet ends of the drying chamber 31 are equipped with flexible sealing curtains.

[0026] An air supply assembly 5 is provided between the inflatable airbag 4 and the drying chamber 31.

[0027] This invention utilizes an expansion bladder 4 to rapidly increase the liquid level, thereby reducing water consumption. The heat from the drying chamber 31 is then transferred to the expansion bladder 4, where it exchanges heat with the liquid in the cleaning tank 1, maintaining the liquid temperature, enhancing solvent activity, and improving cleaning efficiency. This process reduces water consumption and improves energy efficiency.

[0028] The specific operating steps are: 1. First, preheat the drying chamber 31, and then input a certain amount of water and add a certain amount of cleaning agent into the cleaning tank 1;

[0029] 2. Open the air inlet valve and the air outlet valve to connect the drying chamber 31 with the expansion air bag 4. The gas in the drying chamber 31 enters the expansion air bag 4 through the air pump 53. At this time, the expansion air bag 4 expands and heats up.

[0030] 3. When the temperature of the inflatable airbag 4 is higher than the temperature of the liquid, heat conduction will occur, causing the liquid temperature to rise, thereby increasing the activity of the cleaning agent.

[0031] 4. As the inflatable airbag 4 expands, it will occupy the space of the cleaning tank 1, which can quickly raise the liquid level and facilitate the cleaning operation.

[0032] The above conditions require the following: the temperature of the cleaning fluid must be lower than the gas temperature inside the drying chamber 31; the flexible sealing curtain must effectively seal the drying chamber 31, creating a certain heat accumulation effect inside. A temperature detection device is installed inside the cleaning tank.

[0033] The present invention is further configured such that: an airbag frame 41 is provided inside the cleaning tank 1, and an inflatable airbag 4 is installed inside the airbag frame 41, with a conveying gap between the airbag frame 41 and the bottom of the cleaning tank 1 for the packaging bag to pass through. This structural design ensures that the inflatable airbag 4 can inflate in an orderly manner and will not inflate downwards, preventing the packaging bag from passing through.

[0034] This invention is further configured such that the conveying assembly 2 includes a conveyor belt 21 and conveyor plates 22. Multiple sets of conveyor plates 22 are arranged equidistantly along the conveying direction of the conveyor belt 21. During the conveying process, the conveyor plates 22 move through the conveying gap. Due to the absence of gas inside the vacuum packaging bag, its higher density causes it to sink to the bottom of the liquid. Under the action of the conveyor plates 22, it is pushed in the conveying direction, and the cleaning operation is completed during this pushing process.

[0035] The bubble cleaning machine is not shown in the diagram, but it can be installed in the cleaning tank 1 as needed.

[0036] This invention is further configured such that multiple sets of airbag frames 41 and inflatable airbags 4 are arranged equidistantly along the length of the cleaning tank 1. This structural design, by increasing the liquid surface area through multiple sets of inflatable airbags 4, is suitable for use in larger cleaning tanks 1.

[0037] The present invention is further configured such that: the air supply component 5 includes an air inlet pipe 51, an air outlet pipe 52, an air inlet valve, an air outlet valve, and an air pump 53; the expansion airbag 4 is connected to the drying chamber 31 through the air inlet pipe 51 and the air outlet pipe 52 respectively.

[0038] An intake valve and an air pump 53 are installed on the intake pipe 51;

[0039] An exhaust valve is installed on the exhaust pipe 52.

[0040] In this design, the air pump 53, the air inlet valve, and the air outlet valve are all controlled by an external controller.

[0041] When the exhaust valve and the intake valve are opened, the air pump 53 can form a cycle between the expansion air bag 4 and the drying chamber 31, which improves the utilization rate of heat energy and conducts the temperature to the liquid through the expansion air bag 4, so that the temperature of the liquid is maintained.

[0042] The cleaning tank 1 is equipped with a heater, which can maintain a constant temperature. The addition of the inflatable air bladder 4 can reduce the heating frequency of the heater, thereby saving energy.

[0043] This invention is further characterized by having multiple sets of water-permeable holes 411 extending through the airbag frame 41. The design of these water-permeable holes 411 ensures smooth liquid flow.

[0044] The present invention is further configured such that: the conveying assembly 2 also includes a lifting belt 23 and a lifting plate 24, the lifting belt 23 is provided with drainage holes, and multiple sets of lifting plates 24 are provided and are arranged at equal intervals along the conveying direction of the lifting belt 23.

[0045] like Figure 2 As shown, the lifting belt 23 is existing technology and is used to lift the packaging bag into the drying chamber 31, where the height of the drying chamber 31 is higher than the liquid surface.

[0046] The design of this hydrophobic hole enables effective drainage during the transportation process.

[0047] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
