DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Referring to Figures 1 - 4 , the present utility model provides two technical solutions:

[0025] The first implementation mode: A food packaging machine with a sealing structure, including a packaging machine body 1. A sealing mechanism 2 is arranged on the front side of the packaging machine body 1 for sealing the packaging bag. The sealing mechanism 2 includes:

[0026] A sealing component 21, arranged on the front side of the packaging machine body 1 for pressing the packaging bag for sealing. The sealing component 21 includes a groove plate 211 fixedly installed on the front side of the packaging machine body 1. An activity plate 217 is movably installed inside the groove plate 211. A front plate 214 is fixedly installed on the bottom surface of the activity plate 217. An activity groove 2110 is opened on the rear side of the front plate 214. A second heat sealing block 219 is movably installed inside the activity groove 2110;

[0027] The connecting component 22 is arranged inside the active slot 2110 to prevent the second heat-sealing block 219 from damaging the packaging bag. The connecting component 22 includes limiting blocks 228 fixedly installed on the left and right sides of the bottom surface of the active slot 2110. Limiting rods 224 are fixedly installed on both the left and right sides of the active slot 2110. A slider 225 and a spring 227 are movably installed on the outer side of the limiting rod 224. A connecting plate 226 is movably hinged to the rear side of the slider 225. An adjusting component for adjusting the elastic force of the spring 227 is arranged inside the active slot 2110. The adjusting component includes a left-right threaded screw 221 movably installed inside the active slot 2110. Moving blocks 223 are threadedly installed at both the left and right ends of the outer side of the left-right threaded screw 221. A DC motor 222 is fixedly installed on the right side of the front plate 214. One end of the limiting rod 224 movably penetrates through one side of the moving block 223 and is fixedly installed on one side of the limiting block 228. One end of the connecting plate 226 is movably hinged to the front side of the second heat-sealing block 219. The opposite ends of the spring 227 are closely attached to one side of the slider 225. The end of the spring 227 away from the slider 225 is fixedly installed on one side of the moving block 223. And the spring 227 drives the slider 225 to make the second heat-sealing block 219 seal the packaging bag through the connecting plate 226. The left end of the left-right threaded screw 221 threadedly penetrates through one side of the moving block 223 and is movably installed on the left side of the active slot 2110. The right end of the left-right threaded screw 221 movably penetrates through the active slot 2110 and is fixedly installed on the output end of the DC motor 222. And starting the DC motor 222 can drive the moving block 223 to move to compress the spring 227 and adjust the stiffness of the spring 227.

[0028] The extrusion force of the second heat-sealing block 219 can be adjusted through the arranged slider 225 and moving block 223. During use, the elastic force of the spring 227 drives the slider 225 to drive the second heat-sealing block 219 to stick to one side of the packaging bag for sealing. When encountering packaging bags with different thicknesses, start the DC motor 222 to drive the left-right threaded screw 221 to rotate. Then the left-right threaded screw 221 drives the moving block 223 to squeeze the spring 227 to adjust the stiffness of the spring 227, so as to adjust the extrusion force of the second heat-sealing block 219. The elastic force of the spring 227 can prevent the second heat-sealing block 219 from excessively squeezing the packaging bag and causing damage, and it has good practicability.

[0029] The second implementation mode is mainly different from the first implementation mode in that: the sealing component 21 further includes a rear plate 213 fixedly installed at the rear side of the bottom surface of the groove plate 211. An installation groove 215 is formed on the front side of the rear plate 213. A first heat-sealing block 218 is fixedly installed on one side of the installation groove 215, and the first heat-sealing block 218 is located at the rear side of the second heat-sealing block 219. A movable screw 216 is movably installed inside the groove plate 211. A driving motor 212 is fixedly installed on the front side of the groove plate 211. The front end of the movable screw 216 threadedly penetrates through the front side of the movable plate 217 and is movably installed at the rear side of the inner cavity of the groove plate 211. The front end of the movable screw 216 movably penetrates through the inside of the groove plate 211 and is fixedly installed at the output end of the driving motor 212. Starting the driving motor 212 can drive the movable screw 216 to rotate and make the movable plate 217 move back and forth.

[0030] The first heat-sealing block 218 and the second heat-sealing block 219 are provided to facilitate the sealing of the packaging bag. When in use, start the driving motor 212 to drive the movable screw 216 to rotate, and adjust the front plate 214 to a suitable position through the movable plate 217. When the packaging bag passes between the rear plate 213 and the front plate 214, it will squeeze the buckle on the packaging bag to make it closed. At the same time, the first heat-sealing block 218 and the second heat-sealing block 219 can seal the packaging bag, which is simple and convenient and has good practicability.

[0031] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0032] When in use, the user connects the device to electricity, then starts the driving motor 212 to drive the movable screw 216 to rotate, adjusts the front plate 214 to a suitable position through the movable plate 217, then the packaging machine body 1 will load snacks into the packaging bag, and then the conveying device of the packaging machine body 1 will drive the packaging bag to move between the rear plate 213 and the front plate 214. When the packaging bag passes between the rear plate 213 and the front plate 214, it will squeeze the buckle on the packaging bag to make it closed. At this time, the elastic force of the spring 227 can drive the slider 225 to drive the second heat-sealing block 219 to stick to one side of the packaging bag for sealing. When encountering packaging bags with different thicknesses, start the DC motor 222 to drive the forward and reverse screw 221 to rotate, and then the forward and reverse screw 221 will drive the movable block 223 to squeeze the spring 227 to adjust the stiffness of the spring 227 to achieve the adjustment of the extrusion force of the second heat-sealing block 219. The elastic force of the spring 227 can prevent the second heat-sealing block 219 from excessively squeezing the packaging bag and causing damage.
