Technical Field

[0001] This utility model relates to the field of paper bag processing technology, and in particular to a sealing device for paper bag processing. Background Technology

[0002] Packaging paper bags are made from environmentally friendly paper and are lightweight, easy to print on, and biodegradable. They come in various shapes, including tote bags and square-bottom bags, to meet different carrying needs. The surface can be printed with attractive designs and brand information, combining practicality and promotional value. Widely used in shopping, gifts, and food industries, they are a popular choice for green packaging.

[0003] In existing technologies, sealing devices used for paper bag processing are prone to deviation during the paper bag conveying process due to the thin and light material of the paper bags being easily affected by external forces. This causes the paper bags to deviate from the predetermined conveying path, resulting in deviations in the sealing position and quality defects such as incomplete sealing and misalignment. This seriously affects the consistency and pass rate of the finished paper bags, and restricts the improvement of production efficiency and the output of good products.

[0004] To address the above problems, a sealing device for paper bag processing is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bottom sealing device for paper bag processing, aiming to improve the existing bottom sealing devices for paper bag processing, which are often prone to deviation during the paper bag conveying process due to the thin and light material of the paper bag being easily affected by external forces. This causes the paper bag to deviate from the predetermined conveying path, resulting in deviation of the bottom sealing position and causing problems such as incomplete sealing and misalignment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sealing device for paper bag processing, comprising a support base, a U-shaped frame fixedly connected to the top of the support base, a driving component provided on the middle side of the top of the U-shaped frame, a fixing plate provided on the outer side of the driving component, a sealing device installed at the bottom of the fixing plate, a conveyor installed on the inner wall of the U-shaped frame, an anti-deviation component provided on the outer side of the conveyor, and a smoothing component provided on the top of the conveyor;

[0033] Specifically, support base 1 provides a stable support foundation for the entire bottom sealing device; U-shaped frame 2 is used to install drive components and other parts, serving as a load-bearing and fixing function; drive components provide power for bottom sealing device 5 to seal downwards; fixing plate 4 connects and fixes bottom sealing device 5 to ensure stable operation; bottom sealing device 5 is installed at the bottom of fixing plate 4 and is used for sealing the bottom of paper bags by hot pressing or gluing; conveyor 6 is used to transport paper bags, moving them towards the bottom sealing station; support plate 7 and connecting frame 12 support and fix other parts of the anti-deviation component; support frame 8 is used to install motor 9, which provides power to drive turntable 10 to rotate. When turntable 10 rotates, it drives slider 14 to slide in limit groove 13 through connecting rod 11. Limit groove 13 restricts the sliding trajectory of slider 14. Slider 14 drives anti-deviation adjustment plate 16 to move left and right through adjustment frame 15. Anti-deviation adjustment plate 16 is used to correct paper bags that deviate during conveying; smoothing component is set on top of conveyor 6 to smooth the bottom of paper bags and ensure their flatness.

[0034] Reference Figure 3 The smoothing component includes two supports 17. A slide rod 18 is fixedly connected to the inner wall of the support 17. A spring 19 is sleeved on the outer side of the slide rod 18. A moving block 20 is slidably connected to the outer side of the slide rod 18. A smoothing roller 21 is rotatably connected between the two moving blocks 20.

[0035] Specifically, bracket 17 is used to support and fix the smoothing assembly, providing a mounting base for other components; slide bar 18 is fixedly connected to the inner wall of bracket 17, providing sliding guidance for moving block 20; spring 19 is used to provide elastic force to push moving block 20 to drive smoothing roller 21 downward; moving block 20 is used to move up and down under the action of spring 19, and drive smoothing roller 21 to adjust its position; smoothing roller 21 is used to smooth out wrinkles and uneven areas at the bottom of paper bag during paper bag conveying by rolling contact, ensuring that the bottom of paper bag is flat so that the subsequent bottom sealing process can proceed smoothly.

[0036] Reference Figure 1 - Figure 3The drive assembly includes a cylinder 3, which is fixedly connected to the top middle side of the U-shaped frame 2 on the outside. The output end of the cylinder 3 is fixedly connected to the top of the fixed plate 4. The outer side of the moving block 20 is slidably connected to the inner wall of the bracket 17. One end of the spring 19 is fixedly connected to the inner wall of the bracket 17, and the other end of the spring 19 is fixedly connected to the top of the moving block 20. The bottom outer side of the adjusting frame 15 is slidably connected to the top of the connecting frame 12. The anti-deviation adjusting plate 16 is set above the support base 1. One end of the connecting rod 11 is rotatably connected to the top edge of the turntable 10, and the other end of the connecting rod 11 is rotatably connected to the bottom of the slider 14.

[0037] Specifically, cylinder 3 generates telescopic power and is fixedly connected to the top middle side of U-shaped frame 2. Its output end is connected to the top of fixed plate 4, pushing fixed plate 4 and bottom sealing device 5 up and down to achieve bottom sealing. U-shaped frame 2 supports and fixes drive components and other parts, providing a stable frame structure for the entire device. Fixed plate 4 connects cylinder 3 and bottom sealing device 5, transmitting the power of cylinder 3 to bottom sealing device 5 to ensure its stability during the sealing process. Moving block 20 slides on slide bar 18 and, through rotational connection with smoothing roller 21, drives smoothing roller 21 up and down to adapt to different paper bag thicknesses, achieving smoothing operation on the bottom of the paper bag. Bracket 17 fixes slide bar 18, spring 19, and other components, providing installation support for the smoothing assembly. Slide bar 18 provides a sliding track for moving block 20, ensuring the stability and guidance of moving block 20's movement. Spring 19 provides elastic support force, pushing moving block 20 to make smoothing roller 21 contact the paper bag. The bottom of the bag is kept under appropriate pressure to achieve a smoothing effect; the adjusting frame 15 is used to connect the slider 14 and the anti-deviation adjusting plate 16. Driven by the slider 14, the anti-deviation adjusting plate 16 slides on the top of the connecting frame 12, thereby adjusting the position of the anti-deviation adjusting plate 16; the connecting frame 12 is used to support the adjusting frame 15, providing a track and support for the left and right movement of the anti-deviation adjusting plate 16; the anti-deviation adjusting plate 16 is used to move left and right above the support seat 1 to correct the paper bag that deviates during the conveying process and ensure that the paper bag is conveyed along the correct path; the connecting rod 11 is used to connect the turntable 10 and the slider 14, converting the circular motion of the turntable 10 into the linear reciprocating motion of the slider 14 in the limiting groove 13, thereby driving the adjusting frame 15 and the anti-deviation adjusting plate 16 to move; the turntable 10 is used to rotate in a circle under the drive of the motor 9, driving the slider 14 to move through the connecting rod 11; the slider 14 is used to slide in the limiting groove 13, driving the anti-deviation adjusting plate 16 to move left and right through the adjusting frame 15, thereby realizing the anti-deviation adjustment of the paper bag.

[0038] Working principle: A sealing device for paper bag processing. When in operation, the paper bag is placed on the conveyor 6, and the conveyor 6 starts to run, driving the paper bag forward.

[0039] During the paper bag conveying process, when the paper bag passes under the smoothing roller 21, the moving block 20, under the action of the spring 19, drives the smoothing roller 21 to press down, smoothing the uneven parts at the bottom of the paper bag and ensuring that the bottom of the paper bag is flat.

[0040] At the same time, the anti-deviation component plays a role. After the motor 9 starts, its output end drives the turntable 10 to rotate. When the turntable 10 rotates, it drives the slider 14 to slide in the limit groove 13 through the connecting rod 11. The adjustment frame 15 on the top of the slider 14 also moves accordingly, thereby driving the anti-deviation adjustment plate 16 to move left and right above the support seat 1, correcting the paper bags that deviate during the conveying process, ensuring that the paper bags are conveyed along the correct path, and effectively reducing problems such as inaccurate sealing position and unstable quality caused by the deviation of the paper bags.

[0041] When the paper bag is conveyed to the bottom sealing position, the drive assembly starts to work. After the cylinder 3 starts, it pushes the fixing plate 4 to move downward. The bottom sealing device 5 installed at the bottom of the fixing plate 4 then descends to seal the bottom of the paper bag, which has been smoothed and anti-displacement treated and is in an accurate position, thus completing the bottom sealing process of the paper bag.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
