Description

Technical Field

[0001] This utility model relates to the field of quick-frozen corn packaging technology, and more specifically, it relates to a sealing machine specifically for quick-frozen corn. Background Technology

[0002] Quick-frozen corn is a processed food made from carefully selected fresh corn that has been peeled, washed, blanched, and then rapidly frozen, perfectly preserving its sweet taste and rich nutrients. Its plump, golden kernels lock in vitamins, dietary fiber, and minerals. After thawing, it can be used directly in stir-fries, soups, or salads, offering convenient cooking options and year-round enjoyment. Utilizing -18℃ or lower low-temperature freezing technology, it maintains freshness for extended periods without the need for additives, making it an ideal ingredient choice for home kitchens and the catering industry, especially suitable for modern people who prioritize healthy eating in their fast-paced lives.

[0003] In the current process of processing frozen corn, it is first vacuum-frozen and then multiple vacuum-sealed frozen corns are packaged together in one bag. This improves the appearance of the frozen corn packaging, and the packaging bag can be printed with brand, production information and other relevant information for consumers to understand.

[0004] In the process of packaging, the existing technology is mostly carried out in an exposed environment. Since the overall temperature of the production workshop is higher than that of the frozen corn, heat exchange can easily occur between the frozen corn and the working environment during the packaging process, which affects the freezing effect of the frozen corn.

[0005] In addition, in the existing technology, when quick-frozen corn is packaged, the processing part for dispensing and the processing part for sealing are usually set up in two places, and are transported in between by a belt conveyor. After the packaging bags are dispensed, they also need to be transferred for boxing. This makes the production line of quick-frozen corn longer and affects the processing efficiency.

[0036] Please see Figures 1-6As one implementation of the bag-feeding structure: The bag-feeding structure includes a bag inlet 15, which is located on one side of the insulation cover 1. A cutting seat 16 is provided at the top inside the insulation cover 1, and a cutting blade 17 is provided above the cutting seat 16. A fourth electric push rod 18 is provided on the insulation cover 1, and the cutting blade 17 is installed at the output end of the fourth electric push rod 18.

[0039] The present invention provides a guide frame 24 on the inner wall of the heat preservation cover 1. A guide groove 25 is formed between the guide frame 24 and the nearby drive roller 19. The position of the guide groove 25 is matched with the vacuum suction cup 6. Through the cooperation of the guide frame 24 and the guide groove 25, the cut packaging bag can be stably dropped between the two sets of suction cups.

[0040] This utility model has a guide roller 26 at the bag inlet 15, which can reduce the friction of the quick-frozen corn packaging bag at the inlet.

[0041] In summary:

[0042] In use, the packaging bag for sealing is conveyed into the heat insulation cover 1 through the bag inlet 15.

[0043] During this process, the drive motor 20 is started, and the corresponding mounting shaft 21 is rotated through the drive motor 20. The mounting shaft 21 controls the rotation of the corresponding gear 22 and the synchronous belt drive structure 23, thereby realizing the rotation of the corresponding drive roller 19.

[0044] Among them, the two upper and lower drive rollers 19 on the same side rotate relative to each other, the two upper drive rollers 19 rotate synchronously, and the two lower drive rollers 19 rotate synchronously, thereby achieving stable and automatic feeding of the packaging bag when the quick-frozen corn is packaged.

[0045] During this process, the closed end of the packaging bag will enter the loading area formed between the two sets of vacuum suction cups 6 along the guide groove 25 under the action of the guide frame 24, until the cutting gap between the packaging bag used for sealing and the next set of packaging bags reaches the position of the cutting knife 17, and the conveying of the drive roller 19 will stop.

[0046] Simultaneously, the fourth electric push rod 18 is controlled to drive the cutting blade 17 to descend, so that the cutting blade 17 cooperates with the cutting seat 16 to cut the connection of the packaging bag. During this process, the packaging bag can be locked by friction through the drive roller 19 to achieve stable control during the cutting of the packaging bag. In the prior art, a material clamping structure is also assembled on the mold seat of the cutting blade 17, which is a known technology. This utility model does not further limit the clamping during the cutting process, and the existing technology can be fully implemented.

[0047] After the packaging bag is cut, the open end of the packaging bag is obtained, and the drive roller 19 is controlled to continue to transport the packaging bag further until the packaging bag is removed from the drive roller 19 and descends along the guide groove 25 onto the support plate 7;

[0048] During this process, two sets of vacuum suction cups 6 can be controlled to be located on both sides of the packaging bag, so that after the packaging bag is separated from the guide groove 25, it can be pressed and adsorbed. Then, the vacuum suction cups 6 are moved by the second electric push rod 4, so that the vacuum suction cups 6 carry the packaging bag and unfold in the middle position above the support plate 7, so that the opening of the packaging bag is aligned with the discharge tube 2.

[0049] The corn, which has been quick-frozen and vacuum-sealed, is guided into the packaging bag through the feeding pipe 2, achieving stable and precise feeding.

[0050] Once the appropriate amount of quick-frozen corn has been fed, the feeding is stopped. The two sets of vacuum suction cups 6 are brought closer together by the second electric push rod 4. At the same time, the hot pressing strips 5 are brought closer together by the first electric push rod 3, so that the hot pressing strips 5 can achieve the hot pressing seal at the top of the packaging bag. The hot pressing strips 5 can be heated by electric heating wire.

[0051] After sealing is completed, release the vacuum suction cup 6 from the vacuum adsorption on the surface of the packaging bag, and simultaneously control the heat sealing strip 5 to return to its original position;

[0052] At the same time, the third electric push rod 12 is controlled to move the two sets of support plates 7 to the sides respectively, so that the two sets of support plates 7 are opened between them. The frozen corn packaging bag located on the support plate 7 after sealing will automatically fall downward under the action of gravity.

[0053] The receiving box 10 is conveyed to the underside of the support plate 7 by the conveyor belt 9, so that when the quick-frozen corn packaging bag falls, it can land directly into the receiving box 10 and be conveyed by the conveyor belt 9 to realize automatic boxing. The receiving box 10 is preferably an existing foam insulation box.
