DETAILED DESCRIPTION

[0019] The implementation modes of the present invention are described below in conjunction with the accompanying drawings and relevant embodiments. The implementation modes of the present invention are not limited to the following embodiments, and the present invention relates to relevant necessary components in the technical field, which should be regarded as the known technology in the technical field and can be known and mastered by the technical personnel in the technical field.

[0020] like Figures 1 to 5 As shown, a food automatic heat-sealing packaging machine comprises a processing platform 1, a feeding device, a heat-sealing device and a blanking device 2, wherein the feeding device comprises a first feeding track 3 and a second feeding track 4 arranged in the same direction, one end of the processing platform 1 is provided with a first feeding track 3 extending toward the middle of the processing platform 1, and the middle of the processing platform 1 is provided with a second feeding track 4 extending along the length direction of the processing platform 1, and the horizontal height of the first feeding track 3 is higher than the horizontal height of the second feeding track 4; like Figure 1 and Figure 2 As shown, the heat sealing device comprises a longitudinal heat sealing device 5 and a transverse heat sealing device 6 which are sequentially arranged along the conveying direction of the second feeding track 4, and a first driving device 602 for driving the transverse heat sealing device 6 to reciprocate along the horizontal height direction is provided on the processing platform 1, and cutting components 8 with a blade vertically downward are provided on both sides of the transverse heat sealing device 6; In the structure of the processing platform 1 of the present invention, the first loading track 3 is arranged at one end of the processing platform 1 and aligned with the second loading track 4, and is used to transport the food to be packaged to the second loading track 4. The second loading track 4 is arranged in the middle of the processing platform 1. The plastic film for packaging is transported from the bottom of the first loading track 3 toward the second loading track 4 and transported to the top of the sinking groove 101. When the food to be packaged in the first loading track 3 is transported to the second loading track 4, it falls directly on the plastic film. Furthermore, the processing platform 1 is provided with a longitudinal heat sealing device 5 corresponding to the length direction of the lower groove. When the food to be packaged falls on the plastic film, both sides of the plastic film are heat-sealed by the longitudinal heat sealing device 5 during the transportation of the second feeding track 4. The transverse heat sealing device 6 is provided at one end of the second feeding track close to the sunken groove 101 principle. The plastic film that has completed the longitudinal heat sealing is transported to the bottom of the transverse heat sealing device 6, and the first driving device 602 drives the transverse heat sealing device 6 to press down, heat-seal the two ends of the packaging film, and complete the segmentation through the cutting component 8.

[0021] Further, in the structure of the first loading track 3, the first loading track 3 includes a first conveyor belt 301 arranged on the end surface of the processing platform 1, a first winding roller 302 arranged between the end surface of the processing platform 1 and the first conveyor belt 301, and a second winding roller 303 arranged below the processing platform 1, and the end of the first conveyor belt 301 extends to the top of the second loading track 4; like Figure 2 As shown, it should be noted that an unwinding roller for unwinding the plastic mold is provided below the processing platform 1, and the plastic film is sequentially wound around the second winding roller 303 and the second winding roller 303 and then extends to the top of the second feeding track 4, and a plurality of loading platforms 404 are provided on the second feeding track 4, and the plastic film is transported to the upper end surface of the loading platform 404, and the first feeding track 3 transports the food to be packaged to the top of the plastic film corresponding to the position of the loading platform 404; It should be noted that the loading platforms 404 are arranged at equal intervals on the second loading track 4. Correspondingly, the first loading track 3 adopts a loading speed that matches the second loading track 4, and the material interval on the first loading track 3 matches the interval between two adjacent loading platforms on the second loading track 4, so that the food to be packaged on the first loading track 3 can accurately fall on the plastic film at the position corresponding to the loading platform 404; like Figure 2As shown, as an improvement of the above solution, a sinking groove 101 is provided in the middle of the processing platform 1 corresponding to the position of the second loading track 4, and an opening 102 and an opening 2 103 are respectively provided at both ends of the sinking groove 101, and the second conveyor belt 403 penetrates into the sinking groove 101 along the opening 102, and passes out of the sinking groove 101 along the opening 2 103; It should be noted that the horizontal height of the first loading track 3 is higher than the horizontal height of the second loading track 4, the horizontal height of the processing platform 1 is higher than the horizontal height of the second loading track 4, the plastic film is attached to the end surface of the processing platform 1 and covers the notch position of the sunken groove 101, and when the material falls into the second loading track 4 through the first loading track 3, the plastic film is driven by its own weight to fall onto the loading platform 404 synchronously, and at the same time, the material is transported forward synchronously with the loading platform 404 clamping the plastic film by its own weight.

[0022] like Figure 2 and Figure 5 As shown, further, the transverse heat sealing device 6 needs to be pressed down on the stage 404 to achieve heat sealing. During this period, the stage 404 needs to withstand the downward pressure of the transverse heat sealing device 6. The sinking groove 101 is formed by sinking at a position on the surface of the processing platform 1 corresponding to the second loading track 4, and the second conveyor belt 403 is passed along both ends of the sinking groove 101. When the transverse heat sealing device 6 performs transverse heat sealing on the stage 404, the bottom of the stage 404 contacts the bottom of the sinking groove 101, so that the stage 404 can withstand the downward force of the transverse heat sealing device 6 during hot pressing.

[0023] In the structure of the second loading track 4 of the present invention, the second loading track 4 includes a first rotating shaft 401 and a second rotating shaft 402 arranged near the two ends of the processing platform 1, and a second conveyor belt 403 sleeved on the outer surfaces of the first rotating shaft 401 and the second rotating shaft 402, and a plurality of loading platforms 404 are arranged along the length direction of the second conveyor belt 403; It should be noted that the first rotating shaft 401 and the second rotating shaft 402 are respectively arranged at the two ends of the processing platform 1, and the first rotating shaft 401 and the second rotating shaft 402 are arranged horizontally. The first rotating shaft 401 and / or the second rotating shaft 402 rotates while driving the second conveyor belt 403 to rotate. The outer surface of the second conveyor belt 403 is provided with the loading platform 404, and the loading platform 404 is used to carry the food to be packaged; It should be noted that before heat sealing, the plastic film is conveyed to the surface of the loading platform 404 by the first winding roller 302 and the second winding roller 303, the material is conveyed to the plastic film on the first feeding track 3, the packaging film is transversely heat-sealed by the longitudinal heat-sealing device 5, and the two ends of the packaging film at the position of the loading platform 404 are transversely heat-sealed by the transverse heat-sealing device 6, thereby completing the heat sealing of the food.

[0024] like Figure 2 As shown, further, the first rotating shaft 401 and the second rotating shaft 402 are equal polygons of equal size, a second driving device 407 for driving the first rotating shaft 401 to rotate is provided on one side of the first rotating shaft 401, the outer surfaces of the first rotating shaft 401 and the second rotating shaft 402 are tightly fitted with the inner surface of the second conveyor belt 403, the outer surface of the second conveyor belt 403 is provided with the loading platforms 404 at equal intervals, and a gap is reserved between two adjacent loading platforms 404 corresponding to the second conveyor belt 403, It should be noted that the first rotating shaft 401 and the second rotating shaft 402 are equipolygons of equal size. When the first rotating shaft 401 and the second rotating shaft 402 rotate, the second conveyor belt 403 vibrates up and down while conveying forward. The vibration of the second conveyor belt 403 is used to correct the food that falls on the edge of the loading platform 404, so that the food will not be stuck at the edge of the loading platform 404 and affect the heat sealing when it is conveyed to the bottom of the transverse heat sealing device 6. The up and down vibration amplitude of the second conveyor belt 403 is related to the number of side lengths and the rotation speed of the rotating shaft. At the same rotation speed, the more the number of side lengths of the rotating shaft, the smaller the vibration, and vice versa, the smaller the number of side lengths of the rotating shaft, the larger the vibration. In the specific implementation process, the rotation speed of the rotating shaft is adjusted according to the weight of the food to be packaged, so that the position of the food can be corrected by shaking and excessive shaking can be prevented.

[0025] It should be noted that the loading platform 404 is arranged on the second conveyor belt 403, and the second conveyor belt 403 cannot be bent into a certain arc, so when the first rotating shaft 401 and the second rotating shaft 402 are cylinders, the transmission effect cannot be achieved. An equipolygonal cylinder is used as the first rotating shaft 401 and the second rotating shaft 402, and the second conveyor belt 403 is in a crawler type and fits the outer surfaces of the first rotating shaft 401 and the second rotating shaft 402. When the second driving device 407 drives the first rotating shaft 401 to rotate, the second conveyor belt 403 rotates synchronously, thereby driving the second rotating shaft 402 to rotate, and the loading platform 404 on the second conveyor belt 403 matches the outer surfaces of the first rotating shaft 401 and the second rotating shaft 402; Furthermore, in the above scheme, the loading platform 404 is composed of a base 405 and a block 406, the base 405 is rectangular, and the base 405 is fixed on the outer surface of the second conveyor belt 403 at equal intervals, and the block 406 is arranged near the outer edge of the base 405. The number of the block 406 is 4, and they are arranged to form a loading platform 404 with an opening upward. When the material falls onto the loading platform 404 through the first feeding device, under the action of the block 406 and the weight of the material, the two sides of the plastic film stand upright, which is convenient for the longitudinal heat sealing device 5 to heat seal.

[0026] In the structure of the longitudinal heat sealing device 5 of the present invention, the longitudinal heat sealing device 5 comprises a directional wheel 501 and a heat sealing wheel 502 arranged in pairs, a third driving device 503 connected to the directional wheel 501 is arranged below the processing platform 1, the output end of the third driving device 503 is connected to the axis of the directional wheel 501, the outer surfaces of two adjacent directional wheels 501 are in contact with each other, an annular heat sealing strip is wound around the outer surface of the heat sealing wheel 502, and the outer surfaces of two adjacent annular heat sealing wheels 502 are in contact with each other; It should be noted that, under the action of the stopper 406 and the weight of the material, the two sides of the plastic film stand upright, and while the weight of the material and the stage 404 clamp the plastic film and convey it forward synchronously, the longitudinal heat sealing device 5 clamps the erected plastic film through the directional wheel 501 and conveys it to the heat sealing wheel 502 in a close fit, and the two sides of the plastic film are heat-sealed by the heat sealing wheel 502 that is set in a close fit; In the structure of the transverse heat sealing device 6 of the present invention, the transverse heat sealing device 6 includes a fixed bracket 601 fixed to the end face of the processing platform 1, a first driving device 602 arranged above the end of the fixed bracket 601, and a connecting bracket 603 arranged below the end of the fixed bracket 601 and connected to the output end of the first driving device 602. The bottom end face of the connecting bracket 603 is provided with a heat sealing component 7 and a cutting component 8.

[0027] It should be noted that the width dimension of the heat sealing component 7 corresponds to the width dimension of the loading platform 404. When the second loading track 4 moves the plastic film that has completed longitudinal heat sealing to the bottom of the heat sealing component 7, the loading platform 404 is aligned with the heat sealing component 7 in the horizontal height direction, and the first driving device 602 drives the heat sealing component 7 to press down and contact the loading platform 404, thereby heat sealing both ends of the plastic film in the length direction.

[0028] Further, in the above scheme, the heat sealing component 7 includes a first strip heat sealing strip 701 and a second strip heat sealing strip 702 arranged on the bottom end surface of the connecting bracket 603, the first strip heat sealing strip 701 and the second strip heat sealing strip 702 are aligned with the width direction of the second feeding track 4, and the cutting component 8 includes a first blade 801 and a second blade 802 with the blade facing downward, the first blade 801 is fitted on the side of the first strip heat sealing strip 701 away from the second strip heat sealing strip 702, and the second blade 802 is fitted on the side of the second strip heat sealing strip 702 away from the first strip heat sealing strip 701; It should be noted that an elastic component 9 is provided between the rear ends of the first heat-sealing strip 701 and the second heat-sealing strip 702 and the connecting bracket 603, and the elastic component 9 includes a sleeve rod 901 connected between the heat-sealing strip and the connecting bracket 603 and a return spring 902 sleeved on the sleeve rod 901, and the two ends of the return spring 902 are respectively in contact with the back of the heat-sealing strip and the end surface of the connecting bracket 603; When in use, the first blade 801 and the second blade 802 are arranged in contact with the outer surface of the heat sealing component 7, and the horizontal height of the blade edges of the first blade 801 and the second blade 802 is higher than the horizontal height of the strip heat sealing strip. When the heat sealing component 7 is pressed down, the first blade 801 and the second blade 802 are pressed down synchronously. When the heat sealing component 7 is attached to the stage 404 for heat pressing, the first driving device 602 temporarily suspends pressing down. After achieving sufficient heat pressing and sealing, the first driving device 602 drives the heat sealing component 7 to be pressed down, the return spring 902 is compressed, and the heat sealing component 7 maintains the contact state of the stage 404. The first blade 801 and the second blade 802 are driven by the first driving device 602 to press down to cut the heat-sealed plastic film. The contact position between the heat sealing component 7 and the stage 404 is hardened due to the influence of the temperature during hot pressing, which is convenient for the first blade 801 and the second blade 802 to cut.

[0029] Further, in the above scheme, the end of the second loading track 4 in the conveying direction is provided with the blanking device 2, and the blanking device 2 includes a first blanking bracket 201, a second blanking bracket 202 and a blanking frame 203, the top horizontal height of the first blanking bracket 201 is higher than the top horizontal height of the second blanking bracket 202, a bag 204 is connected between the first blanking bracket 201 and the second blanking bracket 202, and the blanking frame 203 is arranged below the second blanking bracket 202; It should be noted that after the loading platform 404 and the heat sealing assembly 7 complete transverse heat sealing and cutting, the second feeding device continues to transport in the direction of the blanking frame 203. Because the second feeding track 4 is a crawler-type rotation, the loading platform 404 flips along the outer surface of the second rotating axis 402 when it is close to the second rotating axis 402, and the heat-sealed food placed on the surface of the loading platform 404 falls onto the bag cloth 204, and slides into the blanking frame 203 through the bag cloth 204, thereby playing a buffering role.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
