Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a three-side sealing equipment for aseptic packaging. Background Technology

[0002] Aseptic packaging refers to packaging materials produced under strictly controlled aseptic conditions to protect the contents from microbial contamination. This type of packaging is widely used in the food (bagged condiments), traditional Chinese medicine (processed medicinal herbs), and cosmetics industries to ensure products remain sterile during transportation and storage, thereby extending shelf life and guaranteeing product quality. Aseptic packaging typically uses multi-layered composite film materials, which have excellent barrier properties, effectively preventing oxygen, moisture, and other contaminants from entering the packaging.

[0003] Commonly used three-side sealing packaging equipment includes vertical packaging machines, whose structure consists of: a frame (the supporting part of the machine, providing the mounting base for other components); a transmission system (providing power to the machine, enabling coordinated operation of all components); a control system (usually using a PLC combined with a touch screen interface, responsible for the automated control of the entire machine, allowing setting and adjustment of packaging parameters such as filling amount and sealing temperature, and possessing fault self-diagnosis functions); a bag-making system (including components such as forming devices, used to form packaging bags of the required shape from the roll film); a filling system (composed of hoppers, metering devices, etc., responsible for accurately filling the packaging bags with materials); a sealing system (including heat sealing or cold sealing devices, used to seal the filled packaging bags); and a finished product output system (generally composed of equipment such as conveyor belts, transporting the packaged finished products to the designated location).

[0004] Existing packaging machines, after sealing the filled bags, require a cutter to separate the seal into two parts. The lower part, containing the contents, falls automatically, while the upper part awaits filling. However, in practice, incomplete cutting often occurs, leading to adhesion and affecting the machine's performance. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the prior art, when dividing filled packaging bags, incomplete cutting and adhesion often occur, and a sterile three-side sealing processing equipment is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A sterile package three-side sealing processing device includes a packaging machine body. The packaging machine body is provided with a film feeding unit, a feeding section, a bag guide, a side sealing unit, and a conveying roller unit. It also includes a horizontal sealing unit, which is installed on the packaging machine body and located below the output end of the feeding section. The horizontal sealing unit has a fixed heat sealing block and a movable heat sealing block. The fixed heat sealing block is fixedly connected to the outer wall of the packaging machine body, and the movable heat sealing block is slidably connected to the packaging machine body. A receiving groove is opened at the horizontal middle position of the movable heat sealing block, and a cutting blade is slidably connected in the receiving groove. A cutting groove corresponding to the receiving groove is opened on the fixed heat sealing block.

[0007] To facilitate horizontal sealing by the horizontal sealing unit, preferably, the horizontal sealing unit also has a fixed plate, the movable heat sealing block is fixedly connected to the inner wall of the fixed plate, and a first cylinder for driving the fixed plate to slide is installed in the packaging machine body. When the first cylinder is activated, the movable heat sealing block moves closer to or away from the fixed heat sealing block.

[0008] To facilitate the cutting blade's division and replacement, a second cylinder is fixedly connected to the fixed plate, and a mounting plate is fixedly connected to the output end of the second cylinder. A slot is provided on the end face of the mounting plate away from the second cylinder. A plug-in plate is fixedly connected to the cutting blade, and one end of the plug-in plate extending out of the receiving groove is slidably connected to the slot. A bolt assembly for fixing the plug-in plate is connected to the mounting plate.

[0009] To improve the cutting effect, preferably, the cutting blade has an arc-shaped structure.

[0010] Preferably, the feeding unit includes a hopper fixedly connected to the top of the packaging machine body, a conveying pipe fixedly connected to the bottom of the hopper, a discharge pipe connected to the conveying pipe through a metering unit, and the discharge pipe extending through the bag guide to the horizontal sealing unit.

[0011] Preferably, the side sealing unit has two side heat sealing blocks that are close to or far apart from each other, and heating wires are fixedly connected inside both side heat sealing blocks, as well as the fixed heat sealing block and the movable heat sealing block.

[0012] Compared with the prior art, this utility model provides a three-side sealing processing equipment for aseptic packages, which has the following beneficial effects: 1. This aseptic bag three-side sealing processing equipment achieves horizontal sealing of the packaging bag by moving the movable heat sealing block closer to the fixed heat sealing block. Since the movable heat sealing block and the fixed heat sealing block have a certain clamping effect on the packaging bag during the horizontal sealing process, and the cutting blade slides from the receiving groove to the cutting groove, it can achieve complete separation, reduce the phenomenon of the upper and lower packaging bags sticking to each other, and improve the use effect.

[0013] 2. This aseptic bag three-side sealing processing equipment uses a fixed connecting plate on the cutting blade, which is then bolted to the mounting plate. This facilitates the replacement of the cutting blade. Furthermore, the cutting blade can be arc-shaped, which can puncture the packaging bag first, making it easier to cut as the cutting blade continues to slide into the blade groove, thus improving the usage effect.

[0014] All parts not mentioned in this device are the same as or can be implemented using existing technology. This utility model achieves horizontal sealing of the packaging bag by moving the movable heat sealing block closer to the fixed heat sealing block. Since the movable heat sealing block and the fixed heat sealing block have a certain clamping effect on the packaging bag during the horizontal sealing process, and the cutting blade slides from the receiving groove to the cutting groove, it can achieve complete separation, reduce the phenomenon of the upper and lower packaging bags sticking to each other, and improve the use effect.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] The working principle of the packaging machine body 1 is as follows: Material feeding: Packaging materials are conveyed to the hopper 7 of the packaging machine through an automatic feeding device to ensure a continuous and stable material supply; Bag forming: Using roll film material, the roll film is rolled into the shape of a bag through a forming device (bag guide 3 and side sealing unit 4). The forming device ensures that the size and shape of the bag meet the preset standards; Filling: After the bag is formed, the material enters the bag through the filling device (feeding pipe, metering unit and discharge pipe 701). The filling device can select different filling methods according to the material characteristics, such as screw filling, bucket elevator, etc.; Sealing: After filling, the top of the packaging bag is automatically sealed (through the horizontal sealing unit 6). The sealing device usually adopts heat sealing or cold sealing technology to ensure that the seal is firm and reliable and to prevent material leakage; Cutting: After sealing, the packaging bag is cut into individual packaging bags by a cutting device (cutting blade 9 and second cylinder 8, etc.). The cutting device usually adopts blade cutting or thermal cutting to ensure neat cuts.

[0020] Example: Reference Figures 1-5A sterile three-side sealing packaging equipment includes a packaging machine body 1, which is equipped with a film feeding unit 2, a feeding section, a bag guide 3, a side sealing unit 4, and a conveying roller unit 5. It also includes a horizontal sealing unit 6 for horizontally sealing the packaging bag, which cooperates with the side sealing unit 4 to achieve three-side sealing of the packaging bag. The horizontal sealing unit 6 is installed on the packaging machine body 1 and is located below the output end of the feeding section. Here, the feeding section includes a hopper 7 fixedly connected to the top of the packaging machine body 1. A conveying pipe is fixedly connected to the bottom of the hopper 7. The conveying pipe is connected to a discharge pipe 701 through a metering unit. The discharge pipe 701 extends through the guide bag component 3 to the horizontal sealing unit 6. The metering unit is preferably a spiral metering tube for conveying. The film feeding unit 2 is an unwinding mechanism used to convey plastic film onto the guide bag component 3. The conveying roller unit 5 consists of two sets of rollers, located below the side sealing unit 4. A motor for driving the rollers to rotate is installed inside the packaging machine body 1. The side sealing unit 4 has two side heat sealing blocks that are close to or far apart from each other. A third cylinder is fixedly connected inside the packaging machine body 1 to drive the side heat sealing blocks to be close to or far apart from each other. When the two side heat sealing blocks are close to each other, the side of the packaging bag is heat-sealed. The guide bag component 3 mainly consists of two parts, namely a round tube. The system uses a cylindrical body shaped like an inverted frustum, with its small end fixedly connected to the top of a cylindrical tube. Furthermore, a limiting ring can be fitted around the outside of the cylindrical body and the cylindrical tube, with a gap between the inner wall of the limiting ring and the outer wall of the cylindrical body and the cylindrical tube to facilitate the guidance and shaping of the plastic film. In use, the plastic film enters the bag guide 3 from the film feeding unit 2. Under the action of the bag guide 3, it is folded in half, and then the side sealing unit 4 seals its sides. The conveying roller unit 5 continues to convey the side-sealed plastic film downwards. The horizontal sealing unit 6 seals the bottom of the initial plastic film. After sealing, the horizontal sealing unit 6 moves away from the plastic film, and filling begins. After filling, the horizontal sealing unit 6 performs a second horizontal seal, this time with a width greater than the initial horizontal seal, facilitating subsequent segmentation from the middle of the horizontal seal to form the top of the lower packaging bag and the bottom of the upper packaging bag. This is a conventional technical solution and will not be elaborated further here.

[0021] Reference Figures 1-3Here, the horizontal sealing unit 6 has a fixed heat-sealing block 601 and a movable heat-sealing block 602. The fixed heat-sealing block 601 is fixedly connected to the outer wall of the packaging machine body 1, and the movable heat-sealing block 602 is slidably connected to the packaging machine body 1. A receiving groove 603 is provided at the horizontal middle position of the movable heat-sealing block 602, and a cutting blade 9 is slidably connected in the receiving groove 603. A cutting edge groove corresponding to the receiving groove 603 is provided on the fixed heat-sealing block 601. Heating wires are fixedly connected in both side heat-sealing blocks and in both the fixed heat-sealing block 601 and the movable heat-sealing block 602. Heating tubes or electric heating wires, preferably electric heating wires, are embedded inside both side heat-sealing blocks and in both the fixed heat-sealing block 601 and the movable heat-sealing block 602. The surfaces are flattened to ensure uniform heat conduction. In use, the movable heat-sealing block 602 moves closer to the fixed heat-sealing block 601 to achieve horizontal sealing of the packaging bag. Since the movable heat-sealing block 602 and the fixed heat-sealing block 601 have a certain clamping effect on the packaging bag during the horizontal sealing process, and the cutting blade 9 slides from the receiving groove 603 into the cutting groove, it can achieve complete separation, reduce the phenomenon of the upper and lower packaging bags sticking to each other, and improve the use effect.

[0022] Reference Figure 4 The horizontal sealing unit 6 also has a fixing plate 604, which fixes the movable heat sealing block 602 to the inner wall of the fixing plate 604. A first cylinder for driving the fixing plate 604 to slide is installed in the packaging machine body 1. When the first cylinder is activated, the movable heat sealing block 602 moves closer to or further away from the fixed heat sealing block 601, thereby achieving horizontal sealing or moving away from the packaging bag, which is convenient to use.

[0023] Reference Figure 1 , Figure 4 and Figure 5A second cylinder 8 is fixedly connected to a fixed plate 604. A mounting plate 801 is fixedly connected to the output end of the second cylinder 8. A slot 802 is provided on the end face of the mounting plate 801 away from the second cylinder 8. A plug-in plate 901 is fixedly connected to the cutting blade 9. One end of the plug-in plate 901 extending into a receiving groove 603 is slidably connected to the slot 802. A bolt assembly for fixing the plug-in plate 901 is connected to the mounting plate 801. A first through hole penetrating the slot 802 is provided on the mounting plate 801. A second through hole corresponding to the first through hole is provided on the plug-in plate 901. A bolt is inserted into both the first and second through holes, and a nut is threaded onto one end of the bolt that passes through the mounting plate 801 to fix the plug-in plate 901. In use, by activating the second cylinder 8, the cutting blade 9 can be driven to slide into the blade groove, thus cutting the packaging bag. The plug-in plate 901 is fixedly connected to the cutting blade 9 and secured to the mounting plate 801 with bolts, facilitating the replacement of the cutting blade 9. The blade of the cutting blade 9 can be flat or curved; here, a curved structure is preferred. The curved structure is convex, which can initially pierce the packaging bag, facilitating cutting as the cutting blade 9 continues to slide into the blade groove, thus improving the effectiveness of use.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
