[0021] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The present invention provides a food packaging sealing device. Figure 1-4As shown, the food packaging sealing device includes: a base 1 and a box body 2 arranged on the base 1; a sealing plate 3 detachably mounted on one side of the box body 2, and a feed port 4 is provided on the sealing plate 3; a group of fixing plates 5 arranged in the box body 2; a group of heating plates 6 fixedly mounted on a group of the fixing plates 5 for sealing the packaging bags; pressing plates 7 respectively arranged on one side of a group of the heating plates 6, and a group of the pressing plates 7 are detachably connected to a group of the fixing plates 5; a finishing mechanism arranged in the box body 2 for smoothing the wrinkles on the surface of the packaging bag; a fixing mechanism arranged on the box body 2 and the sealing plate 3 for fixing the sealing plate 3.

[0023] In this embodiment, the control device first controls the heating plate 6 to heat the pressing plate 7, and then seals the packaging bag. First, the packaging bag is inserted into the box body 2 through the feed port 4, and then the clamping plate 10 clamps the packaging bag between the clamping plate 10 and the placement plate 25 to fix the packaging bag. Then, the sorting mechanism is started to smooth out the wrinkles of the packaging bag. At the same time, the scraper 11 does not separate from the bag during the sorting process, so that the sealing part of the bag is kept in a taut state. Then, a group of first electric telescopic rods 8 are started to drive the pressing plates 7 to slide closer to each other, and the packaging bag is hot-pressed and sealed. After sealing, the bag can be taken out.

[0024] When the pressure plate 7 needs to be replaced, first operate the fixing mechanism to disassemble the sealing plate 3, then remove the bolts on the pressure plate 7 to separate the pressure plate 7 from the fixing plate 5, and then the pressure plate 7 can be removed for replacement. The detachable connection between the pressure plate 7 and the fixing plate 5 makes it simple and quick to replace pressure plates with different patterns, thereby improving the replacement efficiency and flexibility. The existence of the sorting mechanism can ensure that the surface of the packaging bag is flat before sealing, thereby improving the sealing quality and aesthetics. The sealing plate can be disassembled more quickly through the setting of the fixing mechanism.

[0025] In a further preferred embodiment of the present invention, a first electric telescopic rod 8 is fixedly installed in the box body 2, the output rod of the first electric telescopic rod 8 is fixedly connected to the fixed plate 5, and a placement plate 25 is fixedly installed on one side of the sealing plate 3, and the placement plate 25 is located at the lower left of the feed port 4.

[0026] In this embodiment, the packaging bag to be sealed is placed on the placement plate 25, and the packaging bag is fed into the interior of the box body 2 through the feed port 4. The first electric telescopic rod 8 is controlled to extend, so that the fixed plate 5, the heating plate 6 and the pressing plate 7 slide close to each other, and the packaging bag is hot-pressed and sealed. After the sealing is completed, the first electric telescopic rod 8 is controlled to shorten, so that the fixed plate 5, the heating plate 6 and the pressing plate 7 slide away from each other, and then the sealed packaging bag is taken out through the sealing plate 3. The first electric telescopic rod 8 is used to realize automatic control of the sealing components, reducing the difficulty and intensity of manual operation. The design of the placement plate 25 makes the placement and removal of packaging bags more convenient and quick, thereby improving operational efficiency.

[0027] In a further preferred embodiment of the present invention, a second electric telescopic rod 9 is fixedly mounted on one side of the sealing plate 3 , and a clamping plate 10 is fixedly mounted on the output rod of the second electric telescopic rod 9 , and the clamping plate 10 is located above the placement plate 25 .

[0028] In this embodiment, when it is necessary to smooth out the wrinkles of the packaging bag, first insert the packaging bag into the box body 2 through the feed port, then start the second electric telescopic rod 9 to extend its output rod, driving the splint 10 to move downward until the packaging bag is clamped between the splint 10 and the placement plate 25 to fix the packaging bag. After the packaging bag is fixed, the sorting mechanism can be started to smooth out the wrinkles of the packaging bag. Through the setting of the second electric telescopic rod 9 and the splint 10, the packaging bag is firmly fixed, avoiding the movement or deformation of the packaging bag during the wrinkle sorting or sealing process, and improving the sealing quality. The clamping space formed by the splint 10 and the placement plate 25 can quickly and conveniently fix the packaging bag without manual adjustment or fixation, saving operation time and improving overall work efficiency.

[0029] In a further preferred embodiment of the present invention, the finishing mechanism includes: a group of scrapers 11, all arranged in the box body 2, for finishing the wrinkles of the packaging bags; a first cylinder 12 fixedly mounted on one side of the inner wall of the box body 2; a bracket 13 fixedly mounted on the output rod of the first cylinder 12; a group of second cylinders 14, all mounted on the bracket 13, and the output rods of a group of the second cylinders 14 are respectively fixedly connected to a group of the scrapers 11.

[0030] In this embodiment, when the packaging bag enters the box body 2 through the feed port 4, the first cylinder 12 is first started to extend its output rod, driving the bracket 13 and the scraper 11 to slide to the left close to the feed port until the scraper 11 is above the packaging bag. Then, a group of second cylinders 14 are started to extend synchronously. Since a group of scrapers 11 are relatively arranged up and down, the extension of the second cylinders 14 will drive the scrapers 11 to slide relatively close until the scrapers 11 contact the surface of the packaging bag and clamp the packaging bag. After the scraper 11 clamps the packaging bag, the first cylinder 12 is started again to extend its output rod. Recycling, at this time the scraper 11 will slide along the surface of the packaging bag and scrape the wrinkles on the surface of the packaging bag flat. During the entire sorting process, the scraper 11 will never leave the packaging bag, ensuring that the sealing position of the packaging bag is in a tight state, which is convenient for subsequent hot pressing and sealing processing. Through the upper and lower relative setting and synchronous movement of a group of scrapers 11, the surface of the packaging bag can be fully sorted to ensure the flatness and sealing quality of the packaging bag. The introduction of the first cylinder 12 and the second cylinder 14 realizes the automatic control of the scraper 11, reduces the difficulty and intensity of manual operation, and improves production efficiency.

[0031] In a further preferred embodiment of the present utility model, the fixing mechanism includes: an L-shaped plate 16 fixedly installed on one side of the sealing plate 3; a connecting box 17 fixedly installed on one side of the box body 2, and a connecting port for the L-shaped plate 16 to pass through is opened on one side of the connecting box 17; a clamping rod 18 rotatably installed in the connecting box 17, and the clamping rod 18 is L-shaped and clamped with the L-shaped plate 16; a reset spring 19 fixedly installed in the connecting box 17, and one end of the reset spring 19 is fixedly connected to the clamping rod 18.

[0032] When the sealing plate 3 needs to be fixed, the L-shaped plate 16 is aligned with the connection port and pushed in until the right-angled corner of the L-shaped plate 16 contacts the protruding part of the clamping rod 18. At this time, continuing to push the sealing plate 3 will cause the L-shaped plate 16 to squeeze the clamping rod 18, causing it to rotate around the rotation point and compress the return spring 19. When the L-shaped plate 16 completely passes the clamping rod 18, the elastic force of the return spring 19 will cause the clamping rod 18 to rotate back to its original position. At this time, the protruding part of the clamping rod 18 will be stuck in the other right-angled side of the L-shaped plate 16, thereby locking the sealing plate 3. When the sealing plate 3 needs to be removed, it is only necessary to pull the clamping rod 18 to rotate it around the rotation point and stretch the return spring 19 to move the clamping rod 18 away from the L-shaped plate 16 to remove the sealing plate 3. Through the L-shaped plate 16, the connecting box 17, the clamping rod 18 and the return spring 19 and other components, the sealing plate 3 is conveniently locked and unlocked without the need for additional locks or tools, thereby reducing the difficulty of operation.

[0033] In a further preferred embodiment of the present invention, a pull rod 20 is slidingly provided on one side of the connecting box 17, a pull rope 21 is fixedly installed at one end of the pull rod 20, a guide wheel 23 is rotatably installed in the connecting box 17, the pull rope 21 passes around the guide wheel 23 and is fixedly connected to the clamping rod 18, and a pull ring 22 is fixedly installed at one end of the pull rod 20.

[0034] In this embodiment, when it is necessary to unlock and remove the sealing plate 3, the operator only needs to hold the pull ring 22 and pull the pull rod 20 outward. The pull rope 21 will bypass the guide wheel 23 and pull the clamping rod 18 to rotate, so that it is disengaged from the L-shaped plate 16. At this time, the sealing plate 3 can be easily opened or removed, which improves the safety and convenience of the operation.

[0035] In a further preferred embodiment of the present invention, the scraper 11 is arranged in a triangular shape, a protective pad 15 is installed on the scraper 11, a limit block 24 is fixedly installed in the connection box 17, and the limit block 24 is slidably connected to the pull rod 20.

[0036] In this embodiment, the scraper 11 is arranged in a triangular shape. This design enables the scraper 11 to better adapt to the curves and edges of the packaging bags when arranging the packaging bags, thereby improving the arranging effect. At the same time, the protective pad 15 is made of soft and wear-resistant silicone material to protect the packaging bags from being scratched or worn, while increasing the friction between the scraper 11 and the packaging bags to improve the arranging effect. It is slidably connected to the pull rod 20 through the limit block 24. This design limits the moving trajectory of the pull rod 20, ensuring that the pull rod 20 can slide along a predetermined path when moving, thereby avoiding operational errors caused by shaking or offset of the pull rod 20.

[0037] In summary, compared with related technologies, this device can adapt to packaging bags of different specifications and meet the company's needs for different sealing patterns by replacing the pressing plate. At the same time, the pressing plate replacement efficiency is high.

[0038] In the several embodiments provided in this application, it should be understood that the disclosed device can be implemented in other ways.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments. Based on these embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope to be protected by the present invention.
