[0038] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0039] Refer to Figure 1 、 Figure 3 and Figure 4 , an embodiment provided by the present utility model: a sandwich packaging sealing machine, including a frame 1, a vertical plate 3 is fixedly connected to the right side of the top wall of the frame 1, a vertical shell 5 is fixedly connected to the left side of the top wall of the frame 1, an electric push rod 6 is rotatably connected to the left side of the inner wall of the vertical shell 5, the right end of the electric push rod 6 is rotatably connected to an adjusting plate 7, a rotating column 8 is fixedly connected to the bottom wall of the adjusting plate 7, the bottom end of the rotating column 8 is rotatably connected to the left side of the top wall of the frame 1, a plurality of rollers 4 are rotatably connected to the right side of the adjusting plate 7 and the left side of the vertical plate 3 at equal intervals, a conveying device 9 is fixedly installed on the inner wall of the frame 1, a thermal pressing device 11 is fixedly installed on the inner top wall of the vertical shell 5, and a cooling mechanism 2 is provided on the top wall of the vertical shell 5;

[0040] Specifically, by starting the conveying device 9, the sandwich packaging bags placed on the top of the conveying device can be smoothly conveyed. If the sandwich packaging bags are angled off, the electric push rod 6 is started to drive the adjusting plate 7, so that it rotates under the restricted displacement of the rotating column 8, thereby realizing the deflection adjustment of the angle of the sandwich packaging bags. Through the rotation of the adjusting plate 7, the sandwich packaging bags that were originally angled off can be effectively corrected back to the correct position. Multiple rollers 4 assist in the conveying to ensure that the sandwich packaging bags remain stable during the conveying process. The sandwich packaging bags reach the bottom of the hot pressing device 11 smoothly, and the sandwich packaging bags will carry out the sealing work to ensure that each packaging bag can be correctly sealed, effectively avoiding the problem that the packaging bags cannot be sealed due to angle deviation, thereby significantly improving the yield rate of the product.

[0041] Refer to Figure 1 , Figure 2 and Figure 5 , the cooling mechanism 2 includes a protective shell 201. The bottom wall of the protective shell 201 is fixedly connected to the top wall of the vertical shell 5. The inner bottom wall of the protective shell 201 is fixedly connected with a blower 202. The right end of the blower 202 is communicated with a conveying pipe 203. The rear end of the conveying pipe 203 is communicated with a drying box 204. The inner wall of the drying box 204 is fixedly installed with a drying sponge 205. The right end of the drying box 204 is communicated with a connecting pipe 206. The bottom end of the connecting pipe 206 is communicated with a porous nozzle 207. The top wall of the porous nozzle 207 is fixedly connected to the rear side of the inner bottom wall of the vertical shell 5;

[0042] Specifically, by starting the blower 202, it starts to extract the outside air. As the blower operates, the outside air enters the drying box 204 through the conveying pipe 203. There is a drying sponge 205 inside the drying box 204, which can effectively adsorb the water vapor in the air flow. When the air flow containing water vapor passes through the drying sponge 205, the water vapor is absorbed by the drying sponge 205, thereby making the air flow dry. The dried air flow then passes through the connecting pipe 206 and is transmitted to the porous nozzle 207. When the sealed packaging bag comes into contact with these dry and evenly sprayed air flows, the packaging bag will cool down, and since the air flow is dry, there will be no water vapor affecting the sealing effect, ensuring the quality of the seal and significantly improving the cooling efficiency at the same time.

[0043] Refer to Figure 1 , Figure 4 and Figure 5, the cooling mechanism 2 further includes a rubber ring 208. The inner wall of the rubber ring 208 is fixedly installed in the middle of the outer wall of the connecting pipe 206, and the outer wall of the rubber ring 208 is fixedly connected to the right side of the top wall of the vertical shell 5; a control switch 14 is fixedly connected to the top of the front side of the frame 1. The control switch 14 is electrically connected to the blower 202, the conveying device 9, and the electric push rod 6 respectively; both the left and right sides of the frame 1 are fixedly connected with two support seats 15, and support columns 16 are fixedly connected inside the plurality of support seats 15;

[0044] Specifically, the rubber ring 208 enables the contact position between the connecting pipe 206 and the vertical shell 5 to be protected, thereby improving the service life of the connecting pipe 206. The control switch 14, which is electrically connected to the blower 202, the conveying device 9, and the electric push rod 6 respectively, enables the control switch 14 to complete the opening and closing of the device. The support seats 15 and the support columns 16 improve the lateral stability of the device.

[0045] Refer to Figure 1 and Figure 3 , the cooling mechanism 2 further includes a plurality of heat dissipation grooves 209, and the plurality of heat dissipation grooves 209 are respectively opened on the rear side of the protective shell 201; two limiting belts 10 are fixedly connected to the outside of the conveying device 9, and the two limiting belts 10 are both arranged symmetrically; a sloping plate 12 is fixedly connected to the right side of the inner wall of the frame 1, and a plurality of rubber strips 13 are fixedly connected at equal intervals inside the sloping plate 12;

[0046] Specifically, the plurality of heat dissipation grooves 209 improve the heat dissipation effect of the blower 202, thereby reducing the accumulation of heat. The limiting belts 10 enable the conveyance of the sandwich packaging bags to be restricted, thereby effectively avoiding lateral placement. The sloping plate 12 facilitates the guiding of the sealed sandwiches.

[0047] Working principle: When starting to use, by starting the conveying device 9, the sandwich packaging bags placed on its top can be conveyed. Furthermore, when the sandwich packaging bags are placed with an angular deviation, by starting the electric push rod 6, the adjusting plate 7 is driven. Then, under the limited displacement of the rotating column 8 on the adjusting plate 7, the angle is deflected. Thus, through the rotation of the adjusting plate 7, the angular deviation of the sandwich packaging bags can be corrected. Then, with the auxiliary rotation of multiple rollers 4, the conveying of the sandwich packaging bags is completed. Furthermore, the sandwich packaging bags reach the bottom of the hot pressing device 11 for sealing work, avoiding the situation where the packaging bags with angular deviation cannot be sealed. Thus, the yield rate of the product is improved. And by starting the blower 202, it extracts the external air, and the air flow enters the drying box 204 through the conveying pipe 203. Then, the air flow passes through the drying sponge 205, and the water vapor contained in the air flow can be adsorbed by the drying sponge 205. The dried air flow is sprayed through the porous nozzle 207 via the connecting pipe 206, achieving the purpose of quickly cooling the sealed packaging bags, and at the same time, there is no water vapor affecting the sealing effect, thus improving the cooling efficiency.

[0048] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
