[0002] Soy products are foods made from soybeans, mung beans, green beans, peas, broad beans, and other legumes as the main raw materials. Most soy products are tofu and its derivatives, which are made by coagulating soybean milk. Soy products need to be packaged after production, usually using packaging bags.
[0003] In practical use, it was found that traditional equipment relies on manual assistance for positioning the packaging bags, resulting in large positioning errors. This can easily lead to problems such as incomplete sealing and air leakage in the packaging, which not only reduces the product's airtightness but may also cause the product to deteriorate prematurely during transportation and storage. Therefore, we have proposed a rapid sealing device for vacuum packaging of bean products to solve the above problems. Utility Model Content

The vacuum tube 301 is located at the bottom of the lifting plate 201. The vacuum tube 301 and the vacuum pump 3 are connected by the same flexible hose. The vacuum pump 3 is electrically connected to the controller.
[0034] Specifically, the lead screw mechanism includes a lead screw 401 and a lead screw seat 402. The same lead screw 401 is rotatably installed on the inner walls of both sides of the function box 4. The same lead screw seat 402 is threaded onto the lead screw 401. A slide rod 403 is fixedly installed on the inner side of the lead screw seat 402. The other end of the slide rod 403 passes through the function box 4. A connecting plate 404 is fixedly installed on the other end of the slide rod 403. A gear mechanism is provided between the lead screw 401 and the lifting plate 201.
[0035] Specifically, the gear mechanism includes a rack plate 202 and a gear 203. The rack plate 202 is fixedly installed at the bottom of the lifting plate 201. The rack plate 202 is located outside the vacuum tube 301 and is adapted to the through hole 7. The gear 203 is fixedly sleeved on the lead screw 401. The gear 203 is located on the right side of the lead screw seat 402. The rack plate 202 is adapted to the corresponding gear 203.
[0036] Specifically, the positioning mechanism includes a mounting frame 5, a roller 501 and an annular groove 502. The mounting frame 5 is provided inside the connecting plate 404. The roller 501 is rotatably mounted inside the mounting frame 5. The roller 501 has an annular groove 502, which is adapted to the vacuum tube 301. A buffer mechanism is provided between the mounting frame 5 and the connecting plate 404.
[0037] Specifically, the buffer mechanism includes a telescopic rod 503 and a spring 504. The same telescopic rod 503 is provided between the mounting frame 5 and the connecting plate 404. The spring 504 is sleeved on the telescopic rod 503, and the two ends of the spring 504 are fixedly connected to the mounting frame 5 and the connecting plate 404 respectively.
[0038] Specifically, the sealing mechanism includes a heating seat 602 and a heating strip 603. The heating seat 602 is provided at the outer end of the output shaft of the hydraulic cylinder 601, and the heating strip 603 is provided on the inner side of the heating seat 602. The heating seat 602 is electrically connected to the controller.
[0039] In this application, during device operation, the operator first places the packaging bag containing the bean products into the placement box 102. The weighing plate 101 can detect the weight in real time and transmit the data to the controller to ensure that the weight of each package of bean products meets the standard, avoiding the impact on packaging quality and subsequent sales due to insufficient or excessive contents. After the controller confirms that the weight is qualified, it starts the electric push rod 2, whose output shaft pushes the lifting plate 201 to slide down along the inner wall of the housing 1, which can drive the vacuum tube 301 down and extend into the opening of the packaging bag, thus preparing for vacuuming. In the middle, the rack plate 202 at the bottom of the lifting plate 201 moves down synchronously, which can mesh with the gear 203 on the lead screw 401, driving the lead screw 401 to rotate, causing the lead screw seat 402 to move inward along the lead screw 401. It can push the mounting frame 5 and the roller 501 closer to the vacuum tube 301 through the slide rod 403 and the connecting plate 404. It can squeeze the two sides of the packaging bag through the roller 501 and the annular groove 502. The buffer mechanism composed of the spring 504 and the telescopic rod 503 provides elastic support, which can stabilize the packaging bag and avoid damage to the packaging due to excessive clamping force. This system enables precise positioning and protection of the packaging bag, ensuring its stability during vacuuming and sealing. When the lifting plate 201 reaches the set position, the controller activates the vacuum pump 3, which is connected to the vacuum tube 301 via a hose. This pump quickly extracts air from the packaging bag, efficiently removing it to achieve the preset vacuum level. This inhibits oxidation and microbial growth in the bean products, extending their shelf life. After vacuuming, the hydraulic cylinder 601 is activated. Its output shaft pushes the heating seat 602, which in turn moves the heating strip 603 towards the sealing area of the packaging bag, applying pressure. The heating strip 603 rapidly heats up to the set temperature, melting the material at the sealing point. The pressure allows the two layers of material to fuse tightly, forming a strong seal and preventing air from re-entering. After sealing, the controller resets all mechanisms. The electric push rod 2 lifts the lifting plate 201, causing the vacuum tube 301 and roller 501 to detach from the packaging bag. Simultaneously, the lead screw 401 reverses, resetting the roller 501. The hydraulic cylinder 601 retracts the heating seat 602, allowing the operator to remove the packaged bean products.
