Description

Technical Field

[0001] The patent technology field of this utility model belongs to the field of packaging equipment and vacuum technology, specifically relating to an improvement of a manual packaging bag vacuum sealing machine. Background Technology

[0002] Traditional food storage methods make food susceptible to moisture, oxidation, or spoilage, while vacuum sealing technology can effectively extend the shelf life of food. Currently, the most common vacuum sealing equipment on the market includes: Household handheld vacuum sealers: compact and suitable for everyday home use, but with limited vacuuming effect. Industrial-grade vacuum packaging machines: suitable for large-scale production, with strong vacuuming capabilities, but higher equipment cost. Fully automatic vacuum sealers: integrated with an intelligent control system, offering a high degree of automation.

[0003] These devices all have certain shortcomings for everyday household use. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a manual multi-functional vacuum sealing machine. It has a simple and compact structure, is easy to operate, has a stable sealing effect, is low in cost, has a strong vacuuming capacity, good vacuum performance, and can be compatible with bags of various materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes an upper cover 1 and a base 2, the upper cover 1 and the base 2 are connected by a hinge 3 and are fitted together; a sealing strip 4 is provided on the mating surfaces of the upper cover 1 and the base 2, and a vacuum chamber 5 is formed by the sealing strips 4 on both sides after the upper cover 1 and the base 2 are fitted together; a heated sealing metal strip 6 is provided on the inner side of the upper cover 1, and a sealing base 7 is provided on the base 2 corresponding to the heated sealing metal strip 6;

[0006] The upper cover 1 is composed of an upper cover 12 and a lower cover 13, which are fixedly attached to each other to form the upper cover 1. A cavity 14 is provided between the upper cover 12 and the lower cover 13. A vacuum pump 15 and a control circuit board 16 are provided in the cavity 14. The power supply terminal of the vacuum pump 15 is electrically connected to the control circuit board 16. The suction end of the vacuum pump 15 is connected to the suction end 51 of the vacuum chamber 5 through an air pipe. The return air hole 52 of the vacuum chamber 5 is connected to the return air release mechanism 53 through an air pipe.

[0007] The gas return release mechanism 53 includes a fixing plate 531, a spring groove 532, a compression spring 533, a top block 534, and a gas return column 535. The fixing plate 531 and the spring groove 532 are both fixed on the main body of the lower cover 13. One end of the top block 534 extends out of the main body of the lower cover 13, and the other end of the top block 534 is pressed into the spring groove 532 by the compression spring 533. The gas return column 535 is fixedly installed on the top block 534 and is connected to the gas return hole 52 through an air pipe.

[0008] The sealing strip 4 is a rubber strip. The rubber strip is widened and thickened, and rubber strips are set at both the top and bottom. With the thickened and widened rubber strips on both sides, a better sealing effect can be obtained, resulting in less air content in the cavity and a higher vacuum degree, thereby ensuring the vacuum degree inside the packaging bag.

[0009] When the rubber strips are pressed together, they can provide a good seal.

[0010] The vacuum chamber 5 is equipped with a bag opening mechanism 8, which is a columnar mechanism with a forked front end. In use, the two ends of the bag opening are respectively connected to the two bag opening mechanisms 8 to ensure that the air inside the bag is smoothly extracted during vacuuming.

[0011] The upper pressure cover 1 has positioning holes 11 on both sides inside. The base 2 corresponding to the positioning holes 11 is provided with positioning posts 21. The positioning posts 21 are inserted into the positioning holes 11 when the upper pressure cover 1 and the base 2 are in contact with each other. The positioning holes 11 and positioning posts 21 can ensure the stability of the position of the sealing machine during operation, and also ensure the accuracy of vacuuming and sealing positions.

[0012] The sealing base 7 is a semi-circular rubber strip, which is fixed to the base 2. The base 2 is made of a wider and thicker rubber strip. The use of a thicker and wider sealing base 7 can achieve a better sealing effect.

[0013] The workflow of this utility model is as follows:

[0014] Place the bag opening, open the upper pressure cover 1, and the user puts the bag opening that needs to be vacuum sealed into the vacuum chamber 5 of this utility model, and opens the bag opening through the bag opening opening mechanism 8.

[0015] Closing device: When the upper pressure cover 1 is closed, the air in the vacuum chamber 5 is extracted by the vacuum pump. At the same time, because the bag opening is opened for filling, the air inside the bag is also extracted. The bag body can tightly adhere to the material inside the bag, forming a vacuum in the vacuum chamber 5 and inside the bag.

[0016] Sealing: After reaching the preset vacuum level, the equipment starts the heating and sealing metal strip 6 to heat the opening of the packaging bag and press it to complete the sealing.

[0017] Cooling and Completion: After the sealing strip cools down, the equipment stops working, and the user can remove the sealed packaging bag to complete the work.

[0018] By adopting the above technical solution, this utility model uses an optimized vacuum pump system that can quickly and stably extract air from the packaging bag, creating a high vacuum environment inside. This effectively inhibits food oxidation, bacterial growth, and moisture loss, significantly extending the shelf life of food. It is suitable for household, commercial, and industrial food packaging needs.

[0019] It employs a precise temperature control system to ensure uniform sealing temperature, preventing damage to packaging materials due to overheating or weak seals due to insufficient temperature. Combined with appropriate sealing pressure, it ensures a uniform and secure seal, improving packaging integrity and sealing performance, and preventing air backflow and leakage.

[0020] Through a reasonable internal structure design, airflow resistance is reduced, the pumping efficiency of the vacuum pump is improved, the entire vacuum sealing process is made faster, the operation time is shortened, and the work efficiency is improved, making it suitable for continuous sealing needs.

[0021] This utility model equipment is simple to operate, equipped with intelligent buttons or a one-button control system, allowing users to achieve vacuum sealing without complex settings. Some high-end models support multiple sealing modes, such as dry and wet food mode adjustment and adjustable vacuum level, to meet the packaging needs of different types of products.

[0022] This invention provides a vacuum packaging device that not only improves the storage and preservation of food and other items, but also optimizes packaging efficiency and safety. It is applicable to multiple fields such as home, catering, and food processing, and has high market competitiveness. Attached Figure Description
