Description

Technical Field

[0001] This utility model relates to the field of welding wire packaging technology, specifically a welding wire vacuum packaging machine. Background Technology

[0002] A continuous welding wire vacuum packaging machine is a device used for continuous automated vacuum packaging of welding wire. It typically uses belt or chain conveyors to sequentially feed the packaging bags containing the welding wire into the vacuum chamber. After the vacuum chamber is evacuated, the packaging bag is sealed, completing the vacuum packaging process. This allows for continuous, uninterrupted operation. Manually, the welding wire reels (spools) to be packaged are neatly placed into the feeding conveyor belt. The conveyor belt starts, transporting the welding wire reels to the "bag picking / opening station." Once the photoelectric sensor detects the material, the conveyor belt pauses for positioning. After bagging, the conveyor belt restarts, continuously feeding the packaging bags containing the welding wire into the vacuum chamber. After the packaging bags enter the vacuum chamber with the conveyor belt, the vacuum chamber inlet sealing plate presses down, forming a sealed space with the conveyor belt surface. The vacuum pump starts, evacuating the packaging bags from the vacuum chamber through the vacuum pipeline. The air inside the bag exits through the vent at the sealing point. The heating sealing strip inside the vacuum chamber presses down, heat-sealing the packaging bag opening. After sealing, the cooling fan starts, forcibly cooling the sealing area. The vacuum chamber outlet sealing plate lifts, and the conveyor belt continues running, transporting the packaged welding wire reels to the discharge conveyor belt. In the vacuum packaging process of welding wire, the traditional process adopts a step-by-step operation mode of "first heat sealing one side → transfer to the vacuum station to extract vacuum → then heat sealing the other side". It cannot seal both sides of the packaging bag at the same time, then vacuum extract the packaging bag, and then heat seal both sides of the packaging bag after extraction. The heat sealing process needs to be completed in stages, resulting in low work efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a vacuum packaging machine for welding wire to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A welding wire vacuum packaging machine includes an opening component and a movable plate. An extension column is fixedly connected to the bottom end of the movable plate. A hollow column is slidably connected to the bottom end of the extension column. A movable block is fixedly connected to the bottom end of the hollow column. A guide plate is slidably connected to one side of the movable block. A limit frame is slidably connected to the bottom end of the movable block. A connecting component is fixedly connected to one side of the limit frame. A fixed frame is slidably connected to the bottom end of the limit frame. A servo motor is fixedly connected inside the fixed frame. The main body of the packaging machine is fixedly connected to the top of the fixed frame. An auxiliary component includes a sealing plate. An extension component is fixedly connected to the bottom end of the sealing plate. A top block is movably connected to one side of the extension component. One side of the top block is fixedly connected to one side of the hollow column. A guide component is fixedly connected to the top of the fixed frame near the hollow column. A connecting rod is slidably connected inside the guide component. One end of the connecting rod is fixedly connected to one side of the extension column.

[0005] In a preferred embodiment of this utility model, the connecting assembly includes a toothed plate, one side of which is fixedly connected to one side of the limiting frame, and a gear meshing on the surface of the toothed plate, the bottom end of which is fixedly connected to the output end of the servo motor.

[0006] In a preferred embodiment of this utility model, the extension assembly includes an extension plate, the top end of which is fixedly connected to the top end of a sealing plate, and the bottom end of which is slidably connected to a hollow plate, the bottom end of which is fixedly connected to the top end of a fixed frame.

[0007] As a preferred embodiment of this utility model, a groove is provided on one side of the extension plate, and the interior of the groove is movably connected to one side of the top block.

[0008] In a preferred embodiment of this utility model, the guide assembly includes a fixed post, one side of which is fixedly connected to one side of the top block, and a guide frame is fixedly connected to the top of the fixed post. The interior of the guide frame is slidably connected to the surface of the connecting rod.

[0009] As a preferred embodiment of this utility model, a groove is provided at the top edge of the fixed frame, and the interior of the groove is slidably connected to the surface of the hollow column.

[0010] Compared with the prior art, the beneficial effects of this utility model are: By using the movable plate and guide plate, the servo motor drives the gear to rotate during operation. As the gear rotates, it simultaneously moves two toothed plates, causing the two limiting frames to move closer together. During this movement, the two movable blocks within the limiting frames move away from each other along the direction of the guide plate. As the movable blocks move away, the hollow column and extension column drive the two moving plates away from each other, allowing the limiting frames to insert the movable plates into the packaging bag and open their sides. The main body of the packaging machine then performs vacuum packaging, thus improving work efficiency.

[0011] With the extension plate and the movable plate in use, as the limiting frame moves the two movable blocks away from each other, the hollow column and the extension column move together with the movable blocks. The connecting rods on the two extension columns move along the guide frame, and the extension column drives the movable plate to descend. After the movable plate is inserted into the packaging bag, it drives one side of the packaging bag to descend. At the same time, as the hollow column moves, it drives the top block to insert into the groove on the extension plate. As the top block inserts into the extension plate, it drives the extension plate to rise inside the hollow plate. The cooperation between the extension plate and the movable plate makes the two sides of the packaging bag relatively flat, which facilitates the sealing and heat sealing of the packaging bag by the main body of the packaging machine, thereby improving the heat sealing quality.

[0014] 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.

[0015] Example 1 Reference Figure 1 This is the first embodiment of the present invention, which provides a welding wire vacuum packaging machine, including an opening component and a movable plate 10. An extension column 11 is fixedly connected to the bottom end of the movable plate 10, and a hollow column 12 is slidably connected to the bottom end of the extension column 11. A movable block 13 is fixedly connected to the bottom end of the hollow column 12, and a guide plate 14 is slidably connected to one side of the movable block 13. A limiting frame 15 is slidably connected to the bottom end of the movable block 13, and a connecting component 16 is fixedly connected to one side of the limiting frame 15. A fixed frame 17 is slidably connected to the bottom end of the limiting frame 15, and a servo motor 18 is fixedly connected inside the fixed frame 17. A packaging machine body 19 is fixedly connected to the top end of the fixed frame 17. Due to the misalignment design between the moving block 13 and the guide plate 14, during the movement of the limiting frame 15, the two moving blocks 13 inside the limiting frame 15 will move away from each other along the direction of the guide plate 14 within the limiting frame 15, thereby allowing the limiting frame 15 to drive the moving plate 10 to insert into the packaging bag and open its sides during the movement.

[0016] Furthermore, the connecting assembly 16 includes a toothed plate 161, one side of which is fixedly connected to one side of the limiting frame 15. A gear 162 is meshed on the surface of the toothed plate 161, and the bottom end of the gear 162 is fixedly connected to the output end of the servo motor 18.

[0017] The servo motor 18 inside the fixed frame 17 is started by an external power supply, which drives the gear 162 to rotate. During the rotation of the gear 162, the two toothed plates 161 will move simultaneously. As the two toothed plates 161 move, the two limiting frames 15 will move closer to each other, so that the main body of the packaging machine 19 can simultaneously heat seal both sides of the packaging bag.

[0018] Preferably, a groove 26 is provided at the top edge of the fixed frame 17, and the interior of the groove 26 is slidably connected to the surface of the hollow column 12.

[0019] It should be noted that during the movement of the limiting frame 15, the two moving blocks 13 inside the limiting frame 15 will move away from each other in the direction of the guide plate 14 within the limiting frame 15. The moving blocks 13 will drive the hollow column 12 to move together, and the hollow column 12 will also move away from each other in the groove 26 opened at the fixed top, thereby enhancing the stability of the device.

[0020] In use, when the welding wire is placed into the packaging bag and then conveyed to the middle of the fixed frame 17 by the transmission belt, the servo motor 18 inside the fixed frame 17 can be started by an external power supply, so that the servo motor 18 drives the gear 162 to rotate. During the rotation of the gear 162, the two toothed plates 161 will move simultaneously. During the movement of the two toothed plates 161, the two limiting frames 15 will move closer to each other. Due to the misalignment design between the moving block 13 and the guide plate 14, during the movement of the limiting frame 15, the two moving blocks 13 inside the limiting frame 15 will move away from each other along the direction of the guide plate 14. During the movement of the moving blocks 13 away from each other, the hollow column 12 and the extension column 11 will drive the two moving plates 10 away from each other, so that the limiting frame 15 will drive the moving plates 10 to insert into the packaging bag and open its sides during the movement. Then, the packaging machine body 19 will be used to perform vacuum packaging of the packaging bag.

[0021] Example 2 Reference Figure 1 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides auxiliary components, including a sealing plate 20. An extension assembly 21 is fixedly connected to the bottom end of the sealing plate 20. A top block 22 is movably connected to one side of the extension assembly 21. One side of the top block 22 is fixedly connected to one side of the hollow column 12. A guide assembly 23 is fixedly connected to the top of the fixing frame 17 near the hollow column 12. A connecting rod 24 is slidably connected inside the guide assembly 23. One end of the connecting rod 24 is fixedly connected to one side of the extension column 11. The extension assembly 21 includes... The system includes an extension plate 211, the top end of which is fixedly connected to the top end of a sealing plate 20. A hollow plate 212 is slidably connected to the bottom end of the extension plate 211, and the bottom end of the hollow plate 212 is fixedly connected to the top end of a fixing frame 17. A groove 25 is formed on one side of the extension plate 211, and the interior of the groove 25 is movably connected to one side of a top block 22. The guide assembly 23 includes a fixing post 231, one side of which is fixedly connected to one side of a top block 22. A guide frame 232 is fixedly connected to the top end of the fixing post 231, and the interior of the guide frame 232 is slidably connected to the surface of a connecting rod 24. Specifically, the connecting rod 24 on the extension column 11 will move along the guide frame 232. During the movement, the extension column 11 will gradually retract into the hollow column 12, causing the extension column 11 to drive the moving plate 10 to descend. After the moving plate 10 is inserted into the packaging bag, it will drive one side of the packaging bag to descend.

[0022] During use, as the limiting frame 15 moves the two moving blocks 13 away from each other, the hollow column 12 and the extension column 11 move together with the moving block 13. The connecting rods 24 on the two extension columns 11 move along the guide frame 232. During the movement, the extension column 11 gradually retracts into the hollow column 12, causing the extension column 11 to lower the moving plate 10. After the moving plate 10 is inserted into the packaging bag, it causes one side of the packaging bag to lower. At the same time, the movement of the hollow column 12 will cause the top block 22 to move. During the movement, the top block 22 will be inserted into the groove 25 on the extension plate 211. Due to the inclined design of the top block 22, the top block 22 will cause the extension plate 211 to rise inside the hollow plate 212 during the insertion of the top block 22. The cooperation between the extension plate 211 and the moving plate 10 makes the two sides of the packaging bag relatively flat, which facilitates the sealing and heat sealing of the packaging bag by the main body 19 of the packaging machine.
