[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0026] refer to Figure 1The vacuum sealing machine of this embodiment includes a frame 1. A pressing mechanism is provided on the top of the frame 1, and a material discharge trough 3 is provided at the bottom of the pressing mechanism. A heating mechanism 6 is detachably connected to the edge of the material discharge trough 3. The heating mechanism 6 includes a mounting base 601. A baffle 603 is fixedly connected to the top edge of the mounting base 601. A pair of through holes 612 are symmetrically provided on both sides of the bottom of the side wall of the mounting base 601. A guide groove 602 is provided between the through holes 612 and the end side wall of the mounting base 601. A pair of rotating platforms 607 are fixedly connected to both sides of the side wall of the mounting base 601. The rotating platforms 607 are coaxially arranged with the through holes 612 and face the through holes 612. A first rotating rod 611 is rotatably connected to one side of the rotating platform 607. A slot 613 is provided in the middle of the first rotating rod 611, and a gap is left between the first rotating rod 611 and the through hole 612. A second rotating rod 608 is rotatably connected to the side of the rotating platform 607 away from the through hole 612. The second rotating rod 608 is coaxially and fixedly connected to the first rotating rod 611. A conductive connector is fixedly connected to the outer end of the second rotating rod 608, and a pair of butterfly handles 609 are fixedly connected to the side wall of the second rotating rod 608. A positioning pin 610 is provided on the side of the rotating platform 607 away from the guide groove 602 to limit the butterfly handles 609. The slots 613 are symmetrically arranged on opposite side walls. A pair of spring contacts 614 are provided, and the spring contacts 614 are electrically connected to the first rotating rod 611. When installing the heating strip, the heating strip is placed on the top of the mounting base 601, and the heating strip abuts against the stop bar 603 during installation. The stop bar 603 limits the installation position of the heating strip. Then, both ends of the heating strip are bent along the side walls of both ends of the mounting base 601, so that the ends of the heating strip are inserted into the through hole 602 along the guide groove 602. When the ends of the heating strip enter the through hole 612 along the guide groove 602, the butterfly handle 609 is rotated, so that the second rotating rod 608 and the first rotating rod 611 start to rotate. When the butterfly handle 609 rotates to the horizontal position and... When the positioning pin 610 abuts, the groove 613 in the middle of the first rotating rod 611 faces the guide groove 602. After the end of the heating strip enters the through hole 612 along the guide groove 602, it continues to move into the groove 613. At this time, the spring piece 614 inside the groove 613 undergoes elastic deformation, fixing the end of the heating strip inside the groove 613. Then, the butterfly handle 609 is rotated away from the positioning pin 610, causing the second rotating rod 608 and the first rotating rod 611 to rotate accordingly. When the first rotating rod 611 rotates, it causes the end of the heating strip inside its groove 613 to deform accordingly, thereby installing and fixing the end of the heating strip.

[0027] The pressing mechanism includes a mounting frame 2. A first lifting cylinder 4 is vertically fixed to the top of the mounting frame 2. The piston rod of the first lifting cylinder 4 passes through the top of the mounting frame 2 and is horizontally fixed to a pressure plate 5. A pair of second lifting cylinders 7 are symmetrically arranged along the top edge of the pressure plate 5. The second lifting cylinders 7 are vertically arranged with the pressure plate 5. An upper pressure bar 8 is horizontally fixed to the bottom of the piston rod of the second lifting cylinder 7. The heating mechanism 6 is located directly below the upper pressure bar 8. A flat push cylinder 9 is fixedly connected to the top of the side wall of the frame 1 facing the heating mechanism 6. A suction nozzle 10 is fixedly connected to the piston rod of the flat push cylinder 9 for evacuating air from the inside of the packaging bag. When sealing, the packaging bag to be sealed is placed inside the material feeding trough 3, with the edge to be sealed positioned above the heating mechanism 6. At this time, the suction nozzle 10 is pushed into the packaging bag by the flat-push cylinder 9. Then, the first lifting cylinder 4 drives the pressure plate 5 and the second lifting cylinder 7 to move downwards until the pressure plate 5 moves downwards and stops when it contacts the packaging bag to be sealed. The pressure plate 5 initially squeezes out the gas inside the packaging bag and fixes it. At this time, the second lifting cylinder 7 drives the upper pressure bar 8 to move downwards until it abuts against the top of the heating mechanism 6, clamping the opening of the packaging bag to be sealed. Then, the gas inside the packaging bag is extracted by the suction nozzle 10. When the inside of the packaging bag is in a vacuum state, the flat-push cylinder 9 drives the suction nozzle 10 to be pulled out. At this time, the heating component 6 starts heating to seal the opening of the packaging bag.

[0028] A limiting groove 604 is formed on the upper part of the side wall of the mounting base 601. A limiting frame 605 is detachably provided on the outside of the limiting groove 604. Several limiting holes 606 are formed on the side wall of the limiting frame 605 and the top of the side wall of the mounting base 601. The side wall of the limiting frame 605 and the mounting base 601 are connected by a bolt assembly. After the heating strip is installed, high-temperature tape is attached to the top of the mounting base 601 to protect the heating strip. Then, the limiting frame 605 is fitted onto the outside of the limiting groove 604, so that the positions of the limiting holes 606 on the side wall of the limiting frame 605 and the side wall of the mounting base 601 correspond one-to-one. The limiting frame 605 and the mounting base 601 are fixedly connected by the bolt assembly, thereby further fixing the high-temperature tape and the heating strip.

[0029] Working principle: When installing the heating strip, place it on top of the mounting base 601, ensuring it abuts against the stop bar 603. The stop bar 603 limits the installation position of the heating strip. Then, bend both ends of the heating strip along the side walls of the mounting base 601, inserting the end of the heating strip into the through hole 602 along the guide groove 602. When the end of the heating strip enters the through hole 612 along the guide groove 602, rotate the butterfly handle 609, causing the second rotating rod 608 and the first rotating rod 611 to start rotating. When the butterfly handle 609 rotates to a horizontal position and abuts against the positioning pin 610, the first... The groove 613 in the middle of the rotating rod 611 faces the guide groove 602. After the end of the heating strip enters the through hole 612 along the guide groove 602, it continues to move into the groove 613. At this time, the spring piece 614 inside the groove 613 undergoes elastic deformation, fixing the end of the heating strip inside the groove 613. Then, the butterfly handle 609 is rotated away from the positioning pin 610, causing the second rotating rod 608 and the first rotating rod 611 to rotate accordingly. When the first rotating rod 611 rotates, it causes the end of the heating strip inside its groove 613 to deform accordingly, thereby installing and fixing the end of the heating strip.

[0030] After the heating strip is installed, high-temperature tape is attached to the top of the mounting base 601 to protect the heating strip. Then, the limiting bracket 605 is fitted onto the outside of the limiting groove 604, so that the positions of the limiting holes 606 on the side wall of the limiting bracket 605 and the side wall of the mounting base 601 correspond one-to-one. The limiting bracket 605 and the mounting base 601 are fixedly connected by bolt assembly, thereby further fixing the high-temperature tape and the heating strip.

[0031] When sealing, the packaging bag to be sealed is placed inside the material feeding trough 3, with the edge to be sealed positioned above the heating mechanism 6. At this time, the suction nozzle 10 is pushed into the packaging bag by the flat-push cylinder 9. Then, the first lifting cylinder 4 drives the pressure plate 5 and the second lifting cylinder 7 to move downwards until the pressure plate 5 moves downwards and stops when it contacts the packaging bag to be sealed. The pressure plate 5 initially squeezes out the gas inside the packaging bag and fixes it. At this time, the second lifting cylinder 7 drives the upper pressure bar 8 to move downwards until it abuts against the top of the heating mechanism 6, clamping the opening of the packaging bag to be sealed. Then, the gas inside the packaging bag is extracted by the suction nozzle 10. When the inside of the packaging bag is in a vacuum state, the flat-push cylinder 9 drives the suction nozzle 10 to be pulled out. At this time, the heating component 6 starts heating to seal the opening of the packaging bag.

[0032] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
