Description

Technical Field

[0001] This utility model relates to the field of paper roll packaging technology, and in particular to a paper roll vacuum packaging device. Background Technology

[0002] Because paper rolls are susceptible to moisture and dust contamination during storage, transportation, and subsequent processing, and are prone to end-face misalignment and roll diameter deformation when loose, a paper roll vacuum sealing device is established to quickly vacuum and seal the paper rolls, isolate them from external moisture and impurities, fix the internal fiber structure and end-face shape of the paper rolls, ensure the stability of paper roll storage and processing adaptability, and improve the quality control efficiency of the entire paper product production process.

[0003] A search revealed Chinese patent publication number CN220682888U, which discloses a vacuum sealing machine with a double-sided heating structure. The machine includes a worktable and an elastic pressure strip. A fixing block is fixed to the center of the top of the worktable, and an air extraction port is provided on one side of the fixing block. This invention, through the inclusion of a heating mechanism, allows the packaging bag to be placed inside the fixing block. Air is extracted through the extraction port. After extraction, a lifting structure is activated, moving a push plate directly above the packaging bag. The elastic pressure strip simultaneously closes the bag, pressing down on and securing it. The elastic pressure strip ensures the heat-sealing strips on the packaging bag align perfectly. Connecting a heating rod to a power source allows the heating rod to heat the packaging bag via a heating base. This facilitates heating and improves the applicability of the vacuum sealing machine with a double-sided heating structure.

[0004] The aforementioned patent has the following shortcomings: Since the positions of the heating and pressing structures of the existing device are relatively fixed, it can only be adapted to packaging bag sizes of specific specifications. For paper rolls with large differences in diameter and width, it is impossible to flexibly adjust the spacing and height of the pressing components, resulting in poor adaptability of the device to paper rolls of different sizes. When packaging large-diameter or narrow-width paper rolls, it is easy to have poor sealing and incomplete vacuuming, making it difficult to meet diverse paper roll packaging needs.

[0005] To address this, a paper roll vacuum sealing device is proposed. Utility Model Content

[0006] In view of this, the present invention aims to provide a paper roll vacuum sealing device to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of this utility model embodiment is implemented as follows: a paper roll vacuum sealing device, including a frame, and further including: A partition is fixed to the top of the frame, and a sealing strip is fixed to the edge of the top of the partition.

Detailed Implementation

[0022] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0023] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] Example 1: As Figures 1 to 6 As shown, a paper roll vacuum sealing device includes a frame 1, a partition 4 fixed to the top of the frame 1, a sealing strip 3 installed at the edge of the top of the partition 4, a sealing cover 5 correspondingly provided above the sealing strip 3, a spacing adjustment structure 6 installed at both ends of the partition 4, a bag fixing structure 7 for fixing the bag body is provided on one side of the top of the moving plate 601, and a leveling structure 8 for pressing and leveling the surface of the bag body is provided inside the sealing cover 5.

[0026] Support frames 10 are installed at the top of both sides of the frame 1. Hydraulic cylinders 9 are built into the top of the support frames 10, and the telescopic end of the hydraulic cylinders 9 is connected to the sealing cover 5, which can drive the sealing cover 5 to rise and fall. A connecting bucket 12 is fixed at the bottom of the partition 4, and a filter 13 is installed at the bottom of the connecting bucket 12. A vacuum pump 2 is installed on one side inside the frame 1. The input end of the vacuum pump 2 is connected to the filter 13, and air above the partition 4 can be extracted through the connecting bucket 12.

[0027] In this embodiment, when the paper roll vacuum sealing device is needed, the paper roll with the bag attached is placed on top of the partition 4. First, the spacing adjustment structure 6 is used to adjust the position of the bag fixing structure 7 and the heat sealer 11 to adapt to the heat sealing requirements of different specifications of paper rolls. Then, the bag fixing structure 7 is used to fix the position of the openings at both ends of the bag. Subsequently, the hydraulic cylinder 9 is started to drive the sealing cover 5 to move downward until it is in contact with the partition 4. The vacuum pump 2 is started to extract the air between the bag and the partition 4 through the connecting bucket 12. The filter 13 is used to filter the impurities in the extracted air to prevent them from entering the vacuum pump 2. At the same time, the leveling structure 8 presses and flattens the surface of the bag and discharges the gas in the gap of the paper roll. After the vacuum exhaust is completed, the heat sealer 11 is started to seal the bag, thus completing the vacuum sealing of the paper roll.

[0028] like Figures 1 to 4 As shown, the spacing adjustment structure 6 includes a guide rail 604 fixed to the bottom of the partition 4. A movable frame 605 is slidably connected to the outside of the guide rail 604. A movable plate 601 is fixed to the top of the movable frame 605. The movable plate 601 is connected to the heat sealing machine 11. A power component is provided on one side of the movable frame 605. The power component includes a fixed frame 603 fixed inside the connecting bucket 12. A drive motor 602 is installed at the bottom of the fixed frame 603. A gear 608 is fixed to the end of the output shaft of the drive motor 602. A rack 607 is meshed on both sides of the gear 608 and is connected to the movable frame 605. A limit seat 606 is also fixed to the bottom of the partition 4. The rack 607 is slidably connected to the limit seat 606. The two racks 607 are centrally symmetrically distributed on the vertical center line of the gear 608. The movable frame 605 extends upward to the top of the partition 4 and is connected to the movable plate 601.

[0029] In this embodiment, when it is necessary to heat seal bags of different sizes, the drive motor 602 drives the gear 608 to rotate. At the same time, the gear 608 meshes with the racks 607 on both sides, causing the moving frame 605 to slide along the guide rail 604. Simultaneously, the moving frame 605 drives the moving plate 601 to move synchronously, thereby adjusting the distance between the moving plates 601 on both sides to adapt to the heat sealing position of bags of different widths. The sliding direction of the rack 607 is restricted by the limiting seat 606, so that the rack 607 and the gear 608 are tightly meshed. At the same time, the racks 607 are centrally symmetrically distributed to ensure that the moving distance of the moving plates 601 on both sides is consistent.

[0030] Example 2: A paper roll vacuum sealing device. This example is an improvement on Example 1, as follows: Figures 1 to 5 As shown, the bag fixing structure 7 includes a lower clamping plate 701 fixed to one side of the top of the movable plate 601. Guide rods 704 are fixed on both sides of the top of the lower clamping plate 701. An upper clamping plate 702 is slidably connected to the outer side of the guide rods 704. A connecting rod 705 is inserted inside the upper clamping plate 702 and is connected to the lower clamping plate 701. A pressure roller 706 is rotatably connected to the top of the connecting rod 705. A return spring 703 is sleeved on the outer side of the guide rod 704. One end of the return spring 703 is connected to the lower clamping plate 701, and the other end is connected to the upper clamping plate 702.

[0031] In this embodiment, when it is necessary to fix the edge of the bag, the edge of the bag is placed between the lower clamping plate 701 and the upper clamping plate 702, and then the pressure roller 706 is pushed to rotate, so that it presses the upper clamping plate 702, so that the upper clamping plate 702 and the lower clamping plate 701 clamp the bag, thereby preventing the bag from shifting during vacuuming and heat sealing. The guide rod 704 is used to guide the movement direction of the upper clamping plate 702.

[0032] like Figures 1 to 6 As shown, the leveling structure 8 includes multiple sets of buffer springs 805 fixed inside the top of the sealing cover 5. The buffer springs 805 are arranged in a rectangular shape inside the sealing cover 5. The bottom end of the buffer springs 805 is fixed with a leveling plate 801. An electromagnetic vibrator 804 is installed at the top of the leveling plate 801. A limit rod 802 is also fixed at the top of the leveling plate 801. A limit sleeve 803 is sleeved on the outside of the limit rod 802. The limit sleeve 803 is connected to the sealing cover 5, and an elastic buffer pad is installed on the inner side wall of the limit sleeve 803.

[0033] In this embodiment, when the sealing cap 5 moves downward, the flat plate 801 first contacts the surface of the bag, and the buffer spring 805 is compressed to provide buffering force, so that the flat plate 801 fits tightly against the surface of the bag. Then, the electromagnetic vibrator 804 is activated to drive the flat plate 801 to vibrate, pressing and flattening the surface of the bag. At the same time, the vibration accelerates the discharge of gas from the gaps inside the paper roll, improving the vacuum effect and improving the vacuum sealing effect and the storage quality of the paper roll to a certain extent. The movement range of the flat plate 801 is limited by the cooperation of the limiting rod 802 and the limiting sleeve 803, while the elastic buffer pad is used to reduce the vibration transmitted from the limiting rod 802 to the limiting sleeve 803.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
