Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically a double-headed compression sealing bagging device. Background Technology

[0002] The double-head compression sealing bagging device is a piece of equipment used to compress and seal packaging bags. During use, after packaging cotton items, the staff needs to place the packaging bags on the double-head compression sealing bagging device to compress the packaging bags, expel excess air, and then heat seal both ends of the packaging bags, thereby effectively reducing the volume of the packaged products and providing convenience for transportation and handling.

[0003] However, during the compression process, the placement of packaging bags is mostly done manually, which easily leads to uneven placement. This results in discrepancies in the amount of space remaining beyond the heat-sealed lines at both ends of the packaging bags after heat sealing. (See reference...) Figure 6 As shown, this affects the neatness and aesthetics of the compressed packaging bag, thus impacting the quality of the product packaging.

[0004] To address the aforementioned problems, we propose a dual-head compression sealing bagging device. Utility Model Content

[0005] To address the problems in the background art, this utility model provides a double-headed compression sealing bagging device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A double-headed compression sealing bagging device includes a cabinet. A pressing platform is provided at the upper center of the cabinet, and a pressing plate is provided at the upper center of the pressing platform. The pressing plate is driven by a hydraulic cylinder to move up and down. Sealing modules are provided at the center of both ends of the pressing plate. Each sealing module includes a pressing component. A heat sealing knife and a cutting knife are respectively provided at both ends of the pressing component. A support frame is provided at the center of both ends of the pressing plate. Two sets of cylinders are provided at the center of the upper end of the support frame. A lifting plate is connected to the bottom of the cylinders. The pressing component, heat sealing knife, and cutting knife are all fixedly installed on the bottom end face of the lifting plate.

[0008] Preferably, the pressing assembly includes a base plate, which is fixedly installed at the bottom center of the lifting plate. A movable block is movably installed on the inner bottom of the base plate. Multiple sets of springs are provided on the top of the movable block, and a pressing block is provided at the bottom center of the movable block.

[0009] Preferably, a blade holder is provided on the outer side of the bottom end of the lifting plate, and the cutter is fixedly installed on the bottom side of the blade holder by multiple sets of screws.

[0010] Preferably, the upper two sides of the cabinet are provided with material guide grooves, which are located at both ends of the pressing table. A collection box is provided at the end of the material guide groove, and the collection box is movably installed in the middle of the inner side of the cabinet.

[0011] Preferably, the top of the cabinet is equipped with a top plate by four sets of support columns, and the hydraulic cylinder is fixedly installed in the upper middle part of the top plate.

[0012] Preferably, limit guide rods are provided on both sides of the hydraulic cylinder, and the limit guide rods are movably connected to the top plate and fixedly connected to the top of the pressing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this solution, by setting up a pressing component, the bag opening is first pressed and fixed by the pressing component when heat-sealing the bag opening, thereby effectively enhancing the stability of the bag when the heat-sealing knife heat-seals the bag opening, thus improving the quality of the heat-sealing work. In addition, by setting up a cutter, when heat-sealing the bag opening, the cutter can simultaneously cut off the excess part of the bag opening, so that the excess part outside the heat-sealing line at both ends of the bag is of uniform length, thereby effectively improving the neatness of the compressed shape of the bag and enhancing the aesthetics and quality of the compressed packaged product.

[0015] In this solution, the setting of the guide chute and the collection box can guide and collect the cut-off parts of the packaging bag. After the excess parts at both ends of the packaging bag are cut off by the cutter, the excess packaging bag fragments will fall into the guide chute and then be guided into the collection box for centralized collection. This facilitates the cleaning work and prevents the packaging bag fragments from scattering everywhere, which would affect the environmental hygiene of the work area. Attached Figure Description

[0023] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0024] Example: Refer to Figures 1-5 As shown, a double-headed compression sealing bagging device of this embodiment includes a cabinet 1, a pressing platform 2 is provided at the upper middle part of the cabinet 1, and a pressing plate 3 is provided at the upper middle part of the pressing platform 2. The pressing plate 3 is driven by a hydraulic cylinder 4 to move up and down. A sealing module is provided at the middle of both ends of the pressing plate 3. The sealing module includes a pressing component. A heat sealing knife 13 and a cutter 15 are respectively provided at both ends of the pressing component. A support frame 6 is provided at the middle of both ends of the pressing plate 3. Two sets of cylinders 8 are provided at the middle of the upper end of the support frame 6. A lifting plate 7 is connected to the bottom of the cylinders 8. The pressing component, the heat sealing knife 13 and the cutter 15 are all fixedly installed on the bottom end face of the lifting plate 7.

[0025] Hydraulic cylinder 4 pushes the pressing plate 3 down, compressing the packaged product, expelling excess air, and reducing the volume of the product packaging. As the sealing module is pushed down by cylinder 8, the two ends of the packaging bag are first pressed and fixed. Then, the heat sealing knife 13 and the cutter 15 simultaneously heat seal and cut the opening of the packaging bag.

[0026] refer to Figure 5 As shown, when the cutter 15 descends, it will come into contact with the side end face of the pressing table 2, forming a shearing surface, thereby cutting the packaging bag on the pressing table 2.

[0027] In some examples, the pressing assembly includes a base plate 9, which is fixedly installed at the bottom center of the lifting plate 7. A movable block 11 is movably installed on the inner bottom of the base plate 9. Multiple sets of springs 10 are provided on the top of the movable block 11, and a pressing block 12 is provided at the bottom center of the movable block 11. When the pressing assembly presses down, its pressing block 12 will first contact the opening of the packaging bag, thereby pressing and fixing the opening of the packaging bag. This effectively enhances the stability of the heat sealing knife 13 when heat-sealing the packaging bag and the cutting knife 15 when cutting the packaging bag, thereby improving the quality of the heat sealing and cutting processes of the packaging bag.

[0028] In some examples, a blade holder 14 is provided on the outer side of the bottom end of the lifting plate 7, and the cutter 15 is fixedly installed on the bottom side of the blade holder 14 by multiple sets of screws.

[0029] In some examples, guide troughs 16 are provided on both sides of the upper end of the cabinet 1. The guide troughs 16 are located at both ends of the pressing table 2. A collection box 17 is provided at the end of the guide troughs 16. The collection box 17 is movably installed in the middle of the inner side of the cabinet 1. The guide troughs 16 can guide the cut-off packaging bag fragments into the collection box 17 for collection, and then wait for the staff to handle them in a centralized manner, so as to avoid the packaging bag fragments from scattering everywhere and affecting the environmental hygiene of the work area.

[0030] In some examples, the top of the cabinet 1 is fitted with a top plate 18 by four sets of support columns, and a hydraulic cylinder 4 is fixedly installed at the upper middle part of the top plate 18.

[0031] In some examples, limit guide rods 5 are provided on both sides of the hydraulic cylinder 4. The limit guide rods 5 are movably connected to the top plate 18 and fixedly connected to the top of the pressing plate 3. The limit guide rods 5 are mainly used to limit the lifting and sliding of the pressing plate 3, enhance the stability of the pressing plate 3 when it is lifted and lowered, and thus enhance the quality of pressing the packaged product.

[0032] The working principle of this utility model is as follows:

[0033] When in use, first place the packaging bag to be compressed on the pressing table 2, then start the hydraulic cylinder 4, and push the pressing plate 3 through the hydraulic cylinder 4, so that the pressing plate 3 presses down until it presses the packaging bag and the cotton items placed inside the packaging bag, expelling excess air, thereby compressing the items in the packaging bag.

[0034] Then, the cylinders 8 at both ends of the pressing plate 3 are activated, pushing the lifting plate 7 down. The lifting plate 7 drives the sealing module down. The pressing component located at the bottom center of the lifting plate 7 will first press and fix the bag opening of the packaging bag. After the pressing block 12 presses and fixes the bag opening of the packaging bag, as the cylinder 8 continues to push the lifting plate 7 down, the movable block 11 will retract into the base plate 9 under the compression of the spring 10 until the heat sealing knife 13 contacts the bag opening of the packaging bag, thereby performing heat sealing processing on the bag opening of the packaging bag.

[0035] At the same time, when the lifting plate 7 is pressed down, the cutter 15 located at the bottom outer end of the lifting plate 7 will cut off the excess part of the bag opening. As both ends of the bag are cut off by the cutters 15 on both sides, the excess part outside the heat seal line at both ends of the bag is of the same length, thereby effectively improving the neatness of the shape of the bag after compression and enhancing the aesthetics and quality of the packaged product after compression.

[0036] In addition, the setting of the guide trough 16 and the collection box 17 means that after the excess parts at both ends of the packaging bag are cut off by the cutter 15, the excess packaging bag fragments will fall into the guide trough 16 and then be guided by the guide trough 16 into the collection box 17 for centralized collection, which provides convenience for cleaning work.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
