Describe one use process of the present invention below in conjunction with accompanying drawing:

In this embodiment, the upper vacuum chamber 2 cooperates with the lower vacuum chamber 3 to complete the sealing of two food packaging boxes at the same time each time, and according to actual production needs, the upper vacuum chamber 2 and the lower vacuum chamber 3 can be adjusted as needed. The upper vacuum chamber 2 and the lower vacuum chamber 3 contain a larger number of empty spaces for food packaging boxes, so that a larger number of food packaging boxes can be sealed at the same time each time.

Before the official start of the sealing work, the upper vacuum chamber 2 is at a high position, and the lower vacuum chamber 3 is at the filling position of the food packaging box. At this time, the upper vacuum chamber 2 and the lower vacuum chamber 3 are in a staggered state. In this state, the packaging film 10 is first performed. For installation, first put the rolled packaging film 10 on the original film unwinding roller 4, then pull out the end of the packaging film 10, then pull the end of the packaging film 10, bypass the third film guide roller 8 and the first The film guide roller 6 passes between the upper vacuum chamber 2 and the lower vacuum chamber 3, then bypasses the second film guide roller 7 and the film tension roller 9 in turn, and finally is fixed on the waste film recovery roller 5, and then adjusts The position of the film tensioning roller 9 makes the entire packaging film 10 change from a relaxed state to a tensioned state.

After the packaging film 10 is tensioned, the food packaging box containing food can be placed in the lower vacuum chamber 3. The box body of the food packaging box passes through the clamping hole 28 on the edge of the food packaging box, and the edge of the food packaging box is It is supported at the opening of the hole to realize the clamping and positioning of the food packaging box; then start the lower vacuum chamber translational driving cylinder 11, so that the piston rod of the lower vacuum chamber translational driving cylinder 11 is retracted, and the lower vacuum chamber 3 is removed from the food packaging box. Pull the bit back to just below the upper vacuum chamber 2.

After the lower vacuum chamber 3 reaches directly below the upper vacuum chamber 2, the upper vacuum chamber lift driving cylinder 14 is activated, so that the piston rod of the upper vacuum chamber lifting driving cylinder 14 is retracted, and then the force transmission reversing frame 15 is pulled backward until the translation guide The first cylindrical pin 22 at the lower end of the rod 16 slides from the left end of the translation guide hole 20 to the right end, while the second cylindrical pin 23 at the lower end of the lifting guide rod 17 slides from the upper left end of the lifting guide hole 21 to the lower right end until the lifting force transmission rod 18 and the upper vacuum chamber support rod 19 move down synchronously with the lifting guide rod 17, and then the upper vacuum chamber 2 and the lower vacuum chamber 3 are buckled together.

When the upper vacuum chamber 2 and the lower vacuum chamber 3 are buckled together, the packaging film 10 is also clamped between the upper vacuum chamber 2 and the lower vacuum chamber 3, while covering the top of the opening of the food packaging box; then start vacuuming equipment, the air in the upper vacuum chamber 2 and the lower vacuum chamber 3 is exhausted, and then the protective gas supply equipment is started, and the upper vacuum chamber 2 and the lower vacuum chamber 3 are filled with protective gas.

When the protective gas in the upper vacuum chamber 2 and the lower vacuum chamber 3 is fully charged, the food packaging box sealing cylinder 33 is activated, so that the piston rod of the food packaging box sealing cylinder 33 extends downward, and synchronously drives the lower pressure transmission plate 34. Moving downward, during the downward movement of the downward pressure force transmission plate 34, the lamination plate 35 is first pressed on the edge clamping plate 27 of the food packaging box, and at the same time, the packaging film 10 is repositioned. The plate 34 continues to move down, the first return spring 46 is compressed, and the heat-sealing plate 36 continues to follow the downward pressure transfer plate 34 to move downward until the heat-sealing plate 36 presses the packaging film 10 and the edge of the food packaging box against the food packaging in turn. On the box edge clamping plate 27, the packaging film 10 and the edge of the food packaging box are heat-sealed together by the heat sealing plate 36, and the food packaging box is sealed; then the downward pressure force transmission plate 34 will continue to move down, and the second return spring 47 is compressed, the annular cutter 37 will continue to follow the downward pressure transmission plate 34 to move downward until the annular cutter 37 enters the annular groove 29 on the outer periphery of the clamping hole 28 on the edge of the food packaging box, and the packaging film used for sealing. 10 was cut from the entire film strip.

After the packaging film 10 for sealing is cut from the entire film tape, the food packaging box sealing cylinder 33 is reversely activated, so that the piston rod of the food packaging box sealing cylinder 33 is retracted to the initial position, and the annular cutter 37 will As the lower pressure force transmission plate 34 can directly return to the initial position, the lamination plate 35 and the heat sealing plate 36 will be reset with the lower pressure force transmission plate 34 through their respective return springs, and then the lower pressure force transmission plate 36 will be reset. 34 and then pull the lamination plate 35 and the heat sealing plate 36 together to the initial position through the respective guide studs.

When the lamination plate 35 and the heat sealing plate 36 all return to their initial positions, the upper vacuum chamber lift driving cylinder 14 is activated, so that the piston rod of the upper vacuum chamber lifting driving cylinder 14 extends to the left, and then pushes forward the force transmission direction. frame 15 until the first cylindrical pin 22 at the lower end of the translation guide rod 16 slides from the right end of the translation guide hole 20 to the left end, while the second cylindrical pin 23 at the lower end of the lifting guide rod 17 slides from the lower right end of the lifting guide hole 21 to the upper left end , until the lifting force transmission rod 18 and the upper vacuum chamber support rod 19 move up synchronously with the lifting guide rod 17, and the upper vacuum chamber 2 and the lower vacuum chamber 3 are separated.

When the separation of the upper vacuum chamber 2 and the lower vacuum chamber 3 is completed, the lower vacuum chamber translation driving cylinder 11 is activated, so that the piston rod of the lower vacuum chamber translation driving cylinder 11 is extended to the left, and the lower vacuum chamber 3 is moved from the upper vacuum chamber 2 to the front. Push down to the food packaging box filling station, first take out the sealed food packaging box, and then put it into the food packaging box to be sealed; at the same time, the original film feeding roller 4 and the waste film recycling roller 5 rotate synchronously to set the angle Carry out the moving and unloading of the packaging film 10 to prepare for the next sealing.

By repeating the above process, the sealing work of the food packaging box can be carried out continuously.

The solutions in the examples are not intended to limit the scope of patent protection of the present invention, and all equivalent implementations or changes that do not depart from the present invention are included in the scope of the patent of this case.
