[0002] An automatic sealing mechanism for storage bags is an automated device used in the production process of storage bags to seal the opening edges of the bags, thereby achieving the function of storage. However, existing sealing devices for storage bags are fixed during the sealing process and are difficult to adjust. When faced with storage bags of different widths, the sealing cannot be adjusted in advance, thus affecting the overall sealing efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an automatic sealing mechanism for storage bags, which has the advantage of being able to adjust the sealing of storage bags of different widths.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic sealing mechanism for storage bags, including a worktable, a hydraulic sleeve fixedly installed at the bottom of the worktable, a hydraulic rod slidably connected inside the hydraulic sleeve, a spring sleeved on the outside of the hydraulic rod, a top plate fixedly installed above the spring, a sliding groove opened inside the top plate, a slider slidably connected inside the sliding groove, a heating component fixedly installed at the bottom of the slider, and a pressure block fixedly installed at the bottom of the heating component.

[0005] As a preferred embodiment of this utility model, an installation groove is provided above the top plate, and a stud is engaged inside the installation groove, which engages with the slider.

[0006] As a preferred embodiment of this utility model, a hydraulic pump is fixedly installed at the bottom of the workbench, and an oil supply pipe is fixedly installed on the outside of the hydraulic pump. The oil supply pipe is fixedly connected to the hydraulic sleeve.

[0007] As a preferred embodiment of this utility model, a bracket is fixedly installed on the right side of the workbench, a fixed shaft is rotatably connected inside the bracket, and a transmission roller is fixedly installed on the outside of the fixed shaft.

[0008] As a preferred technical solution of this utility model, a fixing plate is fixedly installed above the workbench, a sliding groove is provided inside the fixing plate, a slider is slidably connected inside the sliding groove, a fixing block is fixedly installed on the outside of the slider, and a pressure roller is rotatably connected to the outside of the fixing block.

[0009] As a preferred technical solution of this utility model, a second fixing plate is fixedly installed on the side of the first fixing plate near the pressure roller, a telescopic rod is fixedly installed on the bottom of the second fixing plate, a second spring is sleeved on the outside of the telescopic rod, a connecting plate is provided at the bottom of the second spring, and the connecting plate is fixedly connected to the fixing block.

[0010] As a preferred embodiment of this utility model, there are four hydraulic sleeves and four hydraulic rods. The four hydraulic sleeves are located at the four corners of the workbench, and the four hydraulic rods pass through the interior of the workbench and are fixedly connected to the top plate. There are four springs, and the four springs are fixedly connected to the workbench.

[0011] As a preferred embodiment of this utility model, there are two slide grooves, both of which are located below the mounting groove, and there are four sliders, which are slidably connected to the two slide grooves respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model features a sliding groove inside the top plate, with a slider slidably connected inside the groove. A heating component is fixedly installed at the bottom of the slider, and a pressure block is fixedly installed at the bottom of the heating component. When sealing the edges of a storage bag, the bag is first moved to the top of the worktable. Then, the hydraulic sleeve is activated, causing the hydraulic rod to retract downwards, which in turn moves the top plate downwards. The heating component is then installed at the bottom of the top plate through the sliding action of the slider and the groove. As the top plate moves downwards, it moves the heating component and the pressure block downwards. When the pressure block contacts the storage bag, it seals the edges. Furthermore, because the heating component is installed through the sliding action of the slider and the groove, it allows for easy adjustment of the position of the pressure block to accommodate storage bags of different widths, facilitating the sealing of bags of varying widths.

[0014] 2. This utility model features a groove 2 inside a fixed plate 1, a slider 2 slidably connected inside the groove 2, a fixed block fixedly installed on the outside of the slider 2, and a pressure roller rotatably connected on the outside of the fixed block. When the transmission roller tightens the storage bag, the fixed block is installed above the workbench through the sliding connection between the slider 2 and the groove 2, so that the bottom of the pressure roller contacts the top of the storage bag, and the storage bag is kept flush with the surface of the workbench. This ensures that the surface of the storage bag remains flat, preventing wrinkles from appearing on the surface of the storage bag during edge sealing, thus improving the success rate and aesthetics of edge sealing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides an automatic sealing mechanism for storage bags, including a workbench 1. A hydraulic sleeve 2 is fixedly installed at the bottom of the workbench 1. A hydraulic rod 3 is slidably connected inside the hydraulic sleeve 2. A spring 4 is sleeved on the outside of the hydraulic rod 3. A top plate 5 is fixedly installed above the spring 4. A sliding groove 6 is opened inside the top plate 5. A slider 7 is slidably connected inside the sliding groove 6. A heating component 8 is fixedly installed at the bottom of the slider 7. A pressure block 9 is fixedly installed at the bottom of the heating component 8.

[0023] When sealing the edges of a storage bag is required, first, the area of ​​the storage bag to be sealed is moved to the top of the workbench 1. Then, the hydraulic sleeve 2 is activated, causing the hydraulic rod 3 to retract downwards, which in turn moves the top plate 5 downwards. At this time, the heating component 8 is installed at the bottom of the top plate 5 through the sliding action of the slider 7 and the slide groove 6. As the top plate 5 moves downwards, it will cause the heating component 8 and the pressure block 9 to move downwards. When the pressure block 9 comes into contact with the storage bag, the edge sealing effect is achieved. At the same time, because the heating component 8 is installed through the sliding action of the slider 7 and the slide groove 6, when dealing with storage bags of different widths, the position of the heating component 8 and the pressure block 9 can be easily adjusted through the sliding action of the slider 7 and the slide groove 6, so as to facilitate the edge sealing of storage bags of different widths.

[0024] The top plate 5 has an installation groove 10 on its upper part, and a stud 11 is engaged inside the installation groove 10. The stud 11 engages with the slider 7.

[0025] After the heating component 8 is installed by sliding the slider 7 and the groove 6, the stud 11 engages with the slider 7, thereby fixing the position of the slider 7. This allows for convenient limiting of the heating component 8 and ensures that the heating component 8 will not move arbitrarily.

[0026] The workbench 1 has a hydraulic pump 12 fixedly installed at the bottom, and an oil supply pipe 13 fixedly installed on the outside of the hydraulic pump 12. The oil supply pipe 13 is fixedly connected to the hydraulic sleeve 2.

[0027] The main function of the hydraulic pump 12 is to control the internal hydraulic pressure, so that the hydraulic rod 3 can slide up and down inside the hydraulic sleeve 2 to adjust the height of the top plate 5.

[0028] A bracket 14 is fixedly installed on the right side of the workbench 1. A fixed shaft 15 is rotatably connected inside the bracket 14, and a transmission roller 16 is fixedly installed on the outside of the fixed shaft 15.

[0029] The bracket 14 supports the fixed shaft 15. When the fixed shaft 15 rotates around the bracket 14, the transmission roller 16 will drive the storage bag on the surface, so that the storage bag always remains taut and improves the flatness of the storage bag.

[0030] Among them, a fixed plate 17 is fixedly installed above the workbench 1. A sliding groove 18 is opened inside the fixed plate 17. A slider 19 is slidably connected inside the sliding groove 18. A fixed block 20 is fixedly installed on the outside of the slider 19. A pressure roller 21 is rotatably connected to the outside of the fixed block 20.

[0031] After the transmission roller 16 tightens the storage bag, the fixing block 20 is slidably connected to the slide groove 18 through the slider 19 and installed above the workbench 1, so that the bottom of the pressure roller 21 contacts the top of the storage bag, and at the same time the storage bag is kept flush with the surface of the workbench 1, thereby ensuring that the surface of the storage bag remains flat. When sealing the edges, this prevents wrinkles from appearing on the surface of the storage bag, which could lead to sealing failure, thus improving the success rate and aesthetics of sealing.

[0032] Among them, a second fixed plate 23 is fixedly installed on the side of the first fixed plate 17 near the pressure roller 21. A telescopic rod 24 is fixedly installed at the bottom of the second fixed plate 23. A second spring 25 is sleeved on the outside of the telescopic rod 24. A connecting plate 22 is provided at the bottom of the second spring 25. The connecting plate 22 is fixedly connected to the fixed block 20.

[0033] Spring 25 always provides elastic force to push the connecting plate 22 downward. Since the connecting plate 22 and the fixed block 20 are fixedly connected, the fixed block 20 will drive the pressure roller 21 to squeeze downward, thereby making the pressure roller 21 fit the storage bag more closely.

[0034] There are four hydraulic sleeves 2 and four hydraulic rods 3. The four hydraulic sleeves 2 are located at the four corners of the workbench 1. The four hydraulic rods 3 pass through the inside of the workbench 1 and are fixedly connected to the top plate 5. There are four springs 4. The four springs 4 are fixedly connected to the workbench 1.

[0035] The main function of the four springs 4 is to ensure the overall stability of the device when the four hydraulic rods 3 move up and down, driving the top plate 5 to move up and down, and to prevent the device from shaking too much, which could lead to unstable sealing.

[0036] There are two slide grooves 6, both of which are located below the mounting groove 10. There are four sliders 7, which are slidably connected to the two slide grooves 6 respectively.

[0037] There are two heating components 8, both located at the bottom of the top plate 5. When edge sealing is required, the two heating components 8 are slidably connected to the two sliding grooves 6 via four sliders 7, enabling the two heating components 8 to be quickly installed and disassembled, thereby improving installation and maintenance efficiency.

[0038] Working principle and usage process of this utility model:

[0039] Firstly, a groove 6 is provided inside the top plate 5, and a slider 7 is slidably connected inside the groove 6. A heating component 8 is fixedly installed at the bottom of the slider 7, and a pressure block 9 is fixedly installed at the bottom of the heating component 8. When it is necessary to seal the edge of the storage bag, the storage bag to be sealed is first moved to the top of the workbench 1. At this time, the hydraulic sleeve 2 is activated, causing the hydraulic rod 3 to retract downward, which drives the top plate 5 to move downward. At this time, the heating component 8 is installed at the bottom of the top plate 5 through the sliding action of the slider 7 and the groove 6. When the top plate 5 moves downward, it will drive the heating component 8 and the pressure block 9 to move downward. When the pressure block 9 contacts the storage bag, the edge sealing effect of the storage bag is achieved. At the same time, since the heating component 8 is installed through the sliding action of the slider 7 and the groove 6, when facing storage bags of different widths, the position of the heating component 8 and the pressure block 9 can be easily adjusted through the sliding action of the slider 7 and the groove 6, so as to facilitate the edge sealing effect of storage bags of different widths.

[0040] Secondly, a bracket 14 is fixedly installed on the right side of the workbench 1. A fixed shaft 15 is rotatably connected inside the bracket 14, and a transmission roller 16 is fixedly installed on the outside of the fixed shaft 15. The bracket 14 supports the fixed shaft 15. When the fixed shaft 15 rotates around the bracket 14, the transmission roller 16 will drive the storage bag on the surface, so that the storage bag always remains taut and improves the flatness of the storage bag.

[0041] Finally, a groove 18 is provided inside the fixed plate 17, and a slider 19 is slidably connected inside the groove 18. A fixing block 20 is fixedly installed on the outside of the slider 19, and a pressure roller 21 is rotatably connected on the outside of the fixing block 20. When the transmission roller 16 tightens the storage bag, the fixing block 20 is installed above the workbench 1 through the sliding connection between the slider 19 and the groove 18, so that the bottom of the pressure roller 21 contacts the top of the storage bag, and at the same time, the storage bag is kept flush with the surface of the workbench 1, thereby ensuring that the surface of the storage bag remains flat. When sealing the edges, this prevents wrinkles from appearing on the surface of the storage bag, which could lead to sealing failure, thus improving the success rate and aesthetics of sealing.
