Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to an automated vacuum packaging equipment for materials. Background Technology

[0002] In modern industrial production and product packaging, the demand for vacuum packaging of materials is increasing.

[0003] In the prior art, such as the Chinese patent CN220682777U "A Vacuum Packaging Equipment", there is a main body of the equipment, a sealing device connected to the upper end of the main body, and a filter mechanism installed inside the main body. Its beneficial effect is that when the device vacuum packages meat products, the packaged meat products are first placed inside the main body of the equipment, and the sealing cover is closed to form a sealed space inside the main body of the equipment. The vacuum pump generates a suction force on the drying chamber through the connecting pipe, so that the drying chamber evacuates the inside of the main body of the equipment through the air supply pipe. The air filtered by the filter screen inside the equipment is guided into the drying chamber through the air supply pipe, so that the desiccant adsorbs the water vapor in the air. The dried air moves to the adsorption sponge side by suction force, and the adsorption sponge filters the residual desiccant powder and fine dust in the air, so as to avoid water vapor and dust powder from damaging the vacuum pump.

[0004] However, the vacuum packaging equipment still requires operators to manually open and close the sealing cap during use, and the manual opening and closing method is inefficient. In large-scale production scenarios, frequent manual opening and closing of the sealing cap will consume a lot of time and affect the overall packaging efficiency. In addition, manual operation makes it difficult to ensure the accuracy and consistency of each opening and closing of the sealing cap, which may lead to incomplete sealing and thus affect the quality of vacuum packaging, affecting the shelf life and quality of the materials. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to propose an automated vacuum packaging equipment for materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automated vacuum packaging equipment for materials, comprising a workbench and a top cover, wherein a mounting frame is fixedly installed on the top of the top cover, a vacuum pump is fixedly installed inside the mounting frame, a connecting pipe one is fixedly installed at the input end of the vacuum pump, a connecting pipe two is fixedly installed at the output end of the vacuum pump, an electric telescopic rod is symmetrically fixedly installed on the top of the top of the top cover, a heat sealing knife is fixedly installed at the output end of the electric telescopic rod, a connecting plate is fixedly installed on one side of the top of the workbench, guide rods are symmetrically fixedly installed on the top of the connecting plate, a limit block is fixedly installed at the top end of the guide rod, a motor is fixedly installed at the bottom of the connecting plate, a lead screw is fixedly installed at the output end of the motor, a sliding plate is threadedly connected to the outer wall of the lead screw, and a heat sealing knife holder is symmetrically fixedly installed on the top of the workbench.

[0007] Preferably, the upper cover is fixedly connected to the sliding plate, and the sliding plate is slidably connected to the guide rod.

[0008] Preferably, the connecting pipe is fixedly connected to the upper cover.

[0009] Preferably, a sealing gasket is fixedly installed on the top of the workbench, and the heat sealing knife is slidably connected to the heat sealing knife holder.

[0010] Preferably, the heat-sealing knife holder is rotatably connected to both ends of a rotating shaft, a connecting rod is fixedly installed on the outer wall of the rotating shaft, a metal pressure rod is fixedly installed at the end of the connecting rod away from the rotating shaft, and magnetic strips are symmetrically fixedly installed on the top of the worktable.

[0011] Preferably, the magnetic strip is magnetically connected to the metal pressure rod.

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

[0013] 1. In this utility model, by starting the motor, the motor will drive the lead screw to rotate. Since the lead screw and the sliding plate are threadedly connected, and the sliding plate and the guide rod are slidably connected, the rotation of the lead screw will cause the sliding plate to move up and down along the guide rod. Since the top cover is fixedly connected to the sliding plate, the automatic opening and closing action of the top cover is realized. This design, with the motor driving the top cover to open and close automatically, is much faster than manual operation. Manually opening and closing the top cover frequently is time-consuming and laborious, while the automatic opening and closing device can quickly and continuously complete the opening and closing action of the top cover, greatly saving the time spent opening and closing the cover in each packaging operation, effectively improving the overall packaging efficiency. At the same time, the mechanical structure of the motor drive, lead screw, guide rod and sliding plate can ensure the accuracy and consistency of the opening and closing action of the top cover each time.

[0014] 2. In this utility model, the open end of the packaging bag containing the material is passed between the metal pressure rod and the magnetic strip and placed on the upper surface of the heat sealing knife holder. After placement, the rotating shaft is rotated, causing the connecting rod to drive the metal pressure rod to rotate towards the location of the magnetic strip. After rotating a certain angle, the metal pressure rod will cooperate with the magnetic strip to press the packaging bag. This design ensures that the packaging bag will not shift or loosen during the subsequent vacuum extraction and heat sealing operations, ensuring the accuracy of the entire packaging process.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4As shown, this utility model provides a technical solution: an automated vacuum packaging equipment for materials, including a workbench 1 and a top cover 2. A mounting frame 3 is fixedly installed on the top of the top cover 2. A vacuum pump 4 is fixedly installed inside the mounting frame 3. A connecting pipe 5 is fixedly installed at the input end of the vacuum pump 4, and a connecting pipe 6 is fixedly installed at the output end of the vacuum pump 4. Electric telescopic rods 7 are symmetrically fixedly installed on the top of the top cover 2. A heat sealing knife 8 is fixedly installed at the output end of the electric telescopic rod 7. A connecting plate 9 is fixedly installed on one side of the top of the workbench 1. Symmetrically fixed on the top of the connecting plate 9 are... A guide rod 10 is fixedly installed at the top of the guide rod 10 with a limit block 11. A motor 12 is fixedly installed at the bottom of the connecting plate 9. A lead screw 13 is fixedly installed at the output end of the motor 12. A sliding plate 14 is threadedly connected to the outer wall of the lead screw 13. A heat sealing knife holder 16 is symmetrically fixedly installed on the top of the worktable 1. The upper cover 2 is fixedly connected to the sliding plate 14. The sliding plate 14 is slidably connected to the guide rod 10. The connecting pipe 5 is fixedly connected to the upper cover 2. A sealing gasket 15 is fixedly installed on the top of the worktable 1. The heat sealing knife 8 is slidably connected to the heat sealing knife holder 16.

[0023] In this embodiment, by starting the motor 12, the motor 12 drives the lead screw 13 to rotate. Since the lead screw 13 is threadedly connected to the sliding plate 14 and the sliding plate 14 is slidably connected to the guide rod 10, the rotation of the lead screw 13 causes the sliding plate 14 to move up and down along the guide rod 10. Since the upper cover 2 is fixedly connected to the sliding plate 14, the automatic opening and closing action of the upper cover 2 is realized. This design, driven by the motor 12, achieves an automatic opening and closing speed of the upper cover 2 that is much faster than manual operation. Manually opening and closing the upper cover 2 frequently is time-consuming and laborious, while the automatic opening and closing device can quickly and continuously complete the opening and closing action of the upper cover 2, greatly saving the time spent opening and closing the cover in each packaging operation and effectively improving the overall packaging efficiency. At the same time, the mechanical structure of the motor 12 driving the lead screw 13, guide rod 10 and sliding plate 14 can ensure the accuracy and consistency of each opening and closing action of the upper cover 2.

[0024] Example 2: As Figures 3-4 As shown, the two ends of the heat sealing knife holder 16 are rotatably connected to the rotating shaft 17. The outer wall of the rotating shaft 17 is fixedly installed with the connecting rod 18. The end of the connecting rod 18 away from the rotating shaft 17 is fixedly installed with the metal pressure rod 19. The top of the worktable 1 is symmetrically fixedly installed with magnetic strips 20. The magnetic strips 20 and the metal pressure rod 19 are connected by adsorption.

[0025] In this embodiment, the open end of the packaging bag containing the material is passed between the metal pressure rod 19 and the magnetic strip 20 and placed on the upper surface of the heat sealing knife holder 16. After placement, the rotating shaft 17 is rotated, causing its connecting rod 18 to drive the metal pressure rod 19 to rotate towards the location of the magnetic strip 20. After rotating a certain angle, the metal pressure rod 19 will cooperate with the magnetic strip 20 to press the packaging bag. This design ensures that the packaging bag will not shift or loosen during the subsequent vacuum extraction and heat sealing operations, ensuring the accuracy of the entire packaging process.

[0026] The working principle of this embodiment is as follows: In use, the open end of the packaging bag containing the material is first passed between the metal pressure rod 19 and the magnetic strip 20 and placed on the upper surface of the heat sealing knife holder 16. After placement, the rotating shaft 17 is rotated so that its connecting rod 18 drives the metal pressure rod 19 to rotate towards the location of the magnetic strip 20. After rotating a certain angle, the metal pressure rod 19 will cooperate with the magnetic strip 20 to press the packaging bag. This design ensures that the packaging bag will not shift or loosen during the subsequent vacuum extraction and heat sealing operations, ensuring the accuracy of the entire packaging process. After pressing down the packaging bag, start the motor 12. When the motor 12 is working, it will drive the lead screw 13 to rotate. Since the lead screw 13 is threadedly connected to the sliding plate 14 and the sliding plate 14 is slidably connected to the guide rod 10, the rotation of the lead screw 13 will cause the sliding plate 14 to move up and down along the guide rod 10. Since the upper cover 2 is fixedly connected to the sliding plate 14, the upper cover 2 can be automatically opened and closed. When the upper cover 2 is closed, the vacuum pump 4 is started. The air in the sealed space formed between the upper cover 2 and the worktable 1 is extracted through the connecting pipe 1 5 to realize the vacuum operation. The extracted air is discharged through the connecting pipe 2 6. After the vacuum extraction is completed, start the electric telescopic rod 7. The electric telescopic rod 7 drives the heat sealing knife 8 to move downward, so that the heat sealing knife 8 and the heat sealing knife seat 16 cooperate to perform heat sealing operation on the packaging bag. After the heat sealing operation, the entire vacuum packaging process is completed.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
