[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1-7 , an embodiment provided by the present invention: a vacuum packaging and sealing device for pickled chicken feet, including a support base 1 and a conveyor belt 2. A conveyor belt 2 is installed inside the support base 1, a placing rack 8 is installed on the surface of the conveyor belt 2, a protective cover 3 is fixedly installed on the top of the support base 1, a sealing film rack 4 is fixedly installed on the right side of the protective cover 3, a driving mechanism 5 is arranged on the top of the protective cover 3, and flattening components 6 are arranged on both sides of the driving mechanism 5;

[0029] The driving mechanism 5 includes a telescopic rod 501, a fixing plate 502, a connecting plate 503 and a heat-sealing plate 504. Two groups of telescopic rods 501 are fixedly installed on the top of the protective cover 3. The lower ends of the two groups of telescopic rods 501 are fixedly connected to a fixing plate 502. The lower end of the fixing plate 502 is movably connected to a connecting plate 503. A heat-sealing plate 504 is arranged at the lower end of the connecting plate 503. A stabilizing component 7 is arranged between the fixing plate 502 and the connecting plate 503;

[0030] The flattening component 6 includes a first connecting block 61, a first connecting rod 62, a roller 63, a limiting component 64 and a limiting block 65. Two groups of first connecting blocks 61 are respectively arranged on the front and rear sides of the connecting plate 503. Two groups of first connecting rods 62 are respectively arranged on the left and right sides of the two groups of first connecting blocks 61. A roller 63 is arranged between the lower ends of the front and rear two groups of first connecting rods 62. A limiting component 64 is arranged inside the first connecting block 61. Two groups of limiting blocks 65 are arranged on the lower side of the first connecting block 61;

[0031] Through the arrangement of the flattening component 6 and the stabilizing component 7, this device solves the problems that during the sealing process, it is impossible to ensure that the packaging film is tightly pressed and evenly attached, preventing air from entering the bag; at the same time, the parameter changes of the packaging film and the packaging box affect the sealing effect and are prone to causing damage.

[0032] Furthermore, the stabilizing component 7 includes a fixed rod 71, a second movable rod 72, a second spring 73, a third spring 74, and an adjusting rod 75. Fixed rods 71 are respectively fixedly connected to the four corners on the lower side of the fixed plate 502. A second movable rod 72 is movably connected inside the fixed rod 71. The lower end of the second movable rod 72 passes through the connecting plate 503 and is connected to the heat-sealing plate 504. A second spring 73 is movably sleeved on the outer surface of the second movable rod 72 between the connecting plate 503 and the heat-sealing plate 504. The two ends of the second spring 73 are respectively connected to the inner walls of the connecting plate 503 and the heat-sealing plate 504. A third spring 74 is arranged inside the fixed rod 71 at the top of the second movable rod 72. An adjusting rod 75 is threadedly connected to the top of the fixed rod 71 above the third spring 74. The two ends of the third spring 74 are respectively abutted against the second movable rod 72 and the adjusting rod 75. The adjusting rod 75 passes through the surface of the fixed plate 502. As Figure 5 shown, this structure is used to enable the second spring 73 to contract when the heat-sealing plate 504 contacts packaging films and packaging boxes with different thicknesses. At the same time, the heat-sealing plate 504 drives the second movable rod 72 to rise inside the fixed rod 71, squeezing the third spring 74 and causing the third spring 74 to deform, improving the applicability of the device. When data changes, it can prevent the packaging film and the packaging box from being too tight or having gaps, causing packaging damage. And according to different packaging requirements, the adjusting rod 75 can be rotated to adjust the movement range of the second movable rod 72.

[0033] Furthermore, a fixed plate 502 is fixedly connected to the inner side of the first connecting block 61. The upper end of the first connecting rod 62 is rotatably connected to the first connecting block 61. The other end of the first connecting rod 62 is rotatably connected to the roller 63. As Figure 6 shown, this structure is used to first contact the packaging film through the roller 63. Under the action of the rotational connection of the first connecting rod 62, the packaging film is flattened on the surface of the packaging box, enabling the packaging film to be evenly attached to the surface of the packaging box. At the same time, it prevents dust particles from being caught between the packaging film and the packaging box, improving the sealing effect.

[0034] Further, the limiting component 64 includes a first movable rod 641, a blocking block 642, a first spring 643, and a second connecting rod 644. The first movable rod 641 is movably connected within the first connecting block 61. The lower end of the first movable rod 641 is fixedly connected to the blocking block 642. The outer surface of the first movable rod 641 is movably sleeved with the first spring 643. The two ends of the first spring 643 are respectively abutted against the first connecting block 61 and the blocking block 642. The left and right sides of the blocking block 642 are respectively rotatably connected to the second connecting rods 644. The other ends of the second connecting rods 644 are rotatably connected to the inner sides of the first connecting rods 62. As Figure 6 shown, when the telescopic rod 501 drives the heat-sealing plate 504 to move downward, the blocking blocks 642 on both sides abut against the inner wall of the conveyor belt 2, driving the first movable rod 641 to rise, deforming the first spring 643, and playing a limiting role on the heat-sealing plate 504. And through the second connecting rods 644 rotatably connected to both sides of the blocking block 642 and rotatably connected to the first connecting rods 62, the first connecting rods 62 can move stably.

[0035] Further, a dust removal component 9 is arranged at the left opening of the protective cover 3. The dust removal component 9 includes a curtain 91, a second connecting block 92, and a cleaning wheel 93. A plurality of groups of curtains 91 are rotatably connected at equal intervals at the left opening of the protective cover 3. The bottom of the curtain 91 is fixedly connected to the second connecting block 92. The cleaning wheel 93 is rotatably connected within the second connecting block 92. As Figure 7 shown, this structure is used to provide a certain dust-proof effect on the inside of the protective cover 3 under the protection of the curtain 91 and the cleaning wheel 93, preventing dust from entering the protective cover 3 and affecting the packaging of the product. And through the cleaning wheel 93, the surface of the packaging film after packaging is cleaned, improving the aesthetics of the product.

[0036] Further, four groups of observation windows 10 are respectively rotatably connected to the front and back sides of the protective cover 3. The outer surface of the observation window 10 is fixedly connected to a handle 11. As Figure 4 shown, this structure is used to facilitate the observation of the internal packaging situation through the observation window 10, and through the handle 11, it is convenient to open the observation window 10 for maintaining the internal equipment.

[0037] Further, limiting blocks 65 are located on the left and right sides of the first connecting block 61. Grooves adapted to the first connecting rods 62 are formed within the limiting blocks 65. The limiting blocks 65 are inclined outward. As Figure 6 shown, this structure is used to guide the first connecting rods 62 through the arrangement of the limiting blocks 65, keeping the first connecting rods 62 in an open state all the time, and preventing the rotation of the first connecting rods 62 from being affected.

[0038] Working principle: When in use, as Figure 1As shown, place the packaging box in the placement rack 8, then put the chicken feet into the packaging box, and convey it through the conveyor belt 2. During the conveyance, it passes through the sealing film rack 4, and the packaging film is covered on the surface of the packaging box. As the conveyor belt 2 conveys, when the unsealed packaging box moves to the bottom of the heat-sealing plate 504 through the placement rack 8, the conveyor belt 2 stops conveying. At this time, as Figure 2 and Figure 6 shown, start the telescopic rod 501. When the heat-sealing plate 504 is driven by the telescopic rod 501 to move downward, the roller 63 first contacts the packaging film. Under the action of the rotational connection of the first connecting rod 62, the packaging film is smoothed on the surface of the packaging box, so that the packaging film fits evenly on the surface of the packaging box, and at the same time, it avoids dust particles being caught between the packaging film and the packaging box. With the push of the telescopic rod 501, the abutting blocks 642 on both sides abut against the inner wall of the conveyor belt 2, driving the first movable rod 641 to rise, causing the first spring 643 to deform, playing a limiting role on the heat-sealing plate 504, and through the second connecting rod 644 rotatably connected to both sides of the abutting block 642 and the first connecting rod 62 rotatably connected, the first connecting rod 62 rotates stably. As Figure 5 shown, when the heat-sealing plate 504 contacts the packaging film and the packaging box with different thicknesses, the second spring 73 contracts. At the same time, the heat-sealing plate 504 drives the second movable rod 72 to rise in the fixed rod 71, squeezing the third spring 74, causing the third spring 74 to deform, improving the applicability of the device. As Figure 4 and Figure 7 shown, the sealed packaging box disengages from the inner wall of the protective cover 3 from the left opening of the protective cover 3 and contacts the cleaning wheel 93 at the bottom of the curtain 91 to clean the surface of the packaged packaging film. The above is the entire working principle of the present invention.

[0039] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
