[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] This invention provides a vacuum sealing device to solve the problem that the sealing of notebook monitor packaging bags in the prior art is mainly done manually, which results in low sealing efficiency and unreliable sealing quality.

[0033] Furthermore, the product targeted in this utility model is a laptop monitor packaged in a bag, used to seal the opening of the bag. Of course, the product inside the bag is not limited to a laptop monitor and can also be other products.

[0034] For ease of understanding, the specific processes in the embodiments of this application are described below. Please refer to [link / reference]. Figures 1 to 3 A vacuum sealing device according to an embodiment of this application includes a frame 1, a transmission component 2, a mounting bracket 3, a heat-sealing component 4, a spreading component 5, a pressing component 6, and a vacuuming component 7. The transmission component 2 is mounted on the frame 1 for transmitting packaging bags containing products. The mounting bracket 3 is mounted on the frame 1. The heat-sealing component 4 is mounted on the mounting bracket 3 and located on the side of the opening end of the packaging bag on the transmission component 2 for heat-sealing the opening end. The spreading component 5 is located above and below the packaging bag for opening the opening end of the packaging bag. The pressing component 6 is located at the front end of the heat-sealing component for pressing the opening end of the packaging bag. The vacuuming component 7 is mounted on the mounting bracket and located on one side of the heat-sealing component 4. The vacuuming component can extend forward into the opening end of the packaging bag to vacuum the packaging bag.

[0035] This invention relates to a vacuum sealing device. The device moves the open end of a packaging bag to the spreading component 5 via the transmission component 2. The spreading component 5 expands the open end. Then, the vacuuming component 7 moves into the open end, and the pressing component 6 presses the front end of the open end. The vacuuming component 7 then vacuums the packaging bag. After vacuuming, the vacuuming component 7 retracts, and the hot-melt component 4 seals the packaging bag. Finally, the pressing component and the hot-melt component return to their original positions. The entire process is automated, with high sealing efficiency and quality, meeting the processing needs of enterprises.

[0036] based on Figures 5 to 7 Furthermore, the hot-melt assembly 4 includes a lifting cylinder 40 disposed on the lower surface of the mounting bracket 3, with the piston end of the lifting cylinder 40 facing downwards; the lifting cylinder 40 drives the lifting plate 41 to move up and down below the mounting bracket 3, and the upper surface of the lifting plate 41 is provided with two lifting rods 43 that pass through the bushings of the mounting bracket 3 and extend upwards to the top of the transmission assembly; the tops of the two lifting rods 43 are fixedly connected by a mounting plate 44; the mounting plate 44 is provided with an upper hot-melt part 45 pointing towards the opening end of the packaging bag, and the mounting bracket 3 is provided with a lower hot-melt part 46 corresponding to the upper hot-melt part 45.

[0037] In actual operation, the lifting cylinder 40 drives the upper heat-sealing part 45 to move downward, thereby cooperating with the lower heat-sealing part 46 to seal the opening end of the packaging bag. The sealing operation is completed after the vacuuming component 7 vacuums the packaging bag.

[0038] based on Figure 5 and Figure 7 Furthermore, the opening component 5 includes an upper suction cup 50 and a lower suction cup 51; the lower suction cup 51 is installed inside the lower pressing block 62; a bracket 54 is provided at the front end of the upper heat-melting part 45; a vertical rod 52 is provided on the bracket 54, and the lower suction cup 51, which is compressible by a spring 53, is sleeved inside the vertical rod 52, and the lower suction cup 51 is located above the product in the transfer component 2. When the packaging bag is transferred to one side of the heat-melting component 4, the lower suction cup 50 first adsorbs the lower part of the packaging bag, and then the upper suction cup 50 adsorbs the upper part of the opening end of the packaging bag, thereby opening the opening end of the packaging bag, which facilitates the subsequent vacuuming operation after the vacuuming component 7 enters the packaging bag. The spring 53 is provided to protect the packaging bag and the lower suction cup, and to prevent the lower suction cup 51 from directly colliding with the product in the packaging bag.

[0039] based on Figures 5 to 7 Furthermore, the pressing assembly 6 includes two downward pressing cylinders 60 mounted on the mounting plate 44. The two downward pressing cylinders 60 drive the upper pressing block 61 downwards, and the upper pressing block 61 is located to the right of the upper heat-sealing part 45. Simultaneously, a lower pressing block 62 is located to the right of the lower heat-sealing part 46 on the mounting bracket 3, corresponding vertically to the upper pressing block 61. In actual operation, after the downward pressing cylinders 60 drive the upper pressing block 61 downwards, the upper pressing block 61 and the lower pressing block 62 cooperate to press the open end of the packaging bag, facilitating the subsequent vacuuming operation of the vacuuming assembly 7 and the heat-sealing operation of the heat-sealing assembly on the open end. Here, the upper pressing block 61 is made of a deformable material, thus enabling it to seal the open end when the vacuuming assembly 7 performs vacuuming.

[0040] based on Figure 6 and Figure 8 Furthermore, the vacuuming assembly 7 includes a movable slide rail 70 mounted on the mounting bracket 3, and a vacuum nozzle 72 that can move back and forth via a movable cylinder 71 is provided on the movable slide rail 70. During operation, when the spreading assembly 5 opens the opening of the packaging bag, the vacuum nozzle 72 moves forward under the drive of the movable cylinder 71, thereby extending into the opening. When the pressing assembly presses the opening closed, the vacuum nozzle 72 performs a vacuuming operation on the packaging bag.

[0041] The vacuum nozzle 72 is a flat, elongated shape, which is designed to facilitate the quick entry of the vacuum nozzle into the opening of the packaging bag; of course, its shape is not limited to this and can be adjusted according to actual needs.

[0042] based on Figure 6Furthermore, the mounting bracket 3 is provided with a side guard 8 on one side of the transmission component 2, and the side guard 8 is located on the transmission component 2 on the opposite side from the opening end of the packaging bag. The side guard 8 is rectangular in shape and is used to limit the position of the packaging bag and prevent it from shifting.

[0043] based on Figures 1 to 3 Furthermore, it also includes a feeding mechanism 9 that interfaces with the transmission component 2. The feeding mechanism 9 is used to deliver the packaging bag with the laptop display located at the previous workstation into the transmission component 2. In this embodiment, the feeding mechanism 9 includes multiple transmission rollers 90 arranged perpendicular to the transmission direction of the transmission component 2, that is, if the transmission component 2 is for horizontal transmission, then the transmission rollers 90 are for vertical transmission. Below the multiple transmission rollers 90 is a feeding transmission component that can be raised and lowered by multiple feeding cylinders 91. The feeding transmission component is composed of multiple driveable transmission timing belts 92, and the transmission timing belts 92 are located exactly between the gaps of the multiple transmission rollers 90.

[0044] When the packaging bag is transported to the set position of the transmission roller 90, the feeding cylinder 91 drives the transmission timing belt 92 to be pushed upward from the gap between the transmission rollers 90. The transmission direction of the transmission timing belt 92 is consistent with the direction of the transmission component 2, so that the transmission timing belt 92 can quickly transport the packaging bag from the transmission roller 90 to the transmission component 2.

[0045] based on Figures 1 to 8 The actual application process of this utility model is as follows.

[0046] S1. The transfer roller 90 drives the packaging bag with the display to move above the transfer timing belt 92;

[0047] S2. When the feeding cylinder 91 drives the packaging bag located on the transmission timing belt 92 to be lifted to a certain position, the transmission timing belt 92 connects with the transmission component 2, and the transmission timing belt 92 transfers the product to the transmission component 2.

[0048] S3. The conveying component 2 drives the open end of the packaging bag to be conveyed to the hot melt component 4;

[0049] S4. The lower suction cup 51 adsorbs the lower surface of the packaging bag, and the upper suction cup 50 adsorbs the upper surface of the packaging bag in the air, thereby opening the opening end of the packaging bag.

[0050] S5. The vacuum nozzle 72 moves into the opening end under the drive of the moving cylinder 71;

[0051] S6. The clamping component 6 clamps the open end;

[0052] S7. Vacuum nozzle 72 performs vacuuming operation on the packaging bag;

[0053] S8. After vacuuming is completed, the hot melt assembly 4 seals the packaging bag, and then the hot melt assembly and the pressing assembly return to their original positions, thus completing the automatic sealing operation of the packaging bag.

[0054] This invention relates to a vacuum sealing device that can automatically connect to packaging bags with displays coming from the previous workstation. After the opening end is opened by the spreading assembly, the opening end is pressed by the pressing assembly, and the vacuum assembly vacuums the packaging bag. Finally, the heat-melting assembly completes the sealing operation after heat fusion. The entire process is automated, with high sealing efficiency and the sealing quality is maintained at a high standard, meeting the production and processing needs of enterprises.
