Detailed Description

The present invention will be further described with reference to the accompanying drawings. The utility model provides a product heat-sealing die of function is managed to area, its characterized in that: it comprises an upper die assembly 43 and a lower die assembly 44;

the upper die assembly 43 comprises an upper bottom plate 431, the upper bottom plate 431 is provided with an upper middle die plate 433 through a plurality of upper upright posts 432, the upper middle die plate 433 is connected with an upper pressing plate 435 through spring guide posts 434, the upper pressing plate 435 is provided with a plurality of upper cavities 436, upper heating plates 437 are arranged in the upper cavities 436 and connected with the upper middle die plate 433, upper heating rings 438 are arranged on the upper heating plates 437 in a downward protruding manner corresponding to the outer contour of the packing box, the outer contour of the upper heating plates 437 is provided with cutter rings 439, and the cutter rings 439 are connected with the upper middle die plate 433;

the lower mold assembly 44 comprises a lower base plate 441, a lower panel 442 covers the lower base plate 441, a lower cavity 443 is arranged on the lower panel 442, a lifting area 444 is formed by hollowing out the middle of the lower cavity 443, a lower supporting plate 445 is installed in the lifting area 444 and connected with the lower jacking mechanism 5, and a vacuum groove 446 connected with a vacuum pump is arranged on the periphery of the lower cavity 443.

The middle part of the upper heating plate 437 is recessed inwards to form a clearance cavity 4310, and a heat insulation plate 4311 is arranged in the clearance cavity 4310.

The cutter ring 439 is designed into a ring shape similar to the shape of the shell of the product, and a serrated knife 4391 is arranged on the lower end face of the cutter ring.

The end face of the heat insulation plate 4311 is higher than the end face of the heating ring 438.

The outer contour of the lower cavity 443 is provided with a support ring, and the surface of the support ring is covered with a sealing ring 447.

The front end and the rear end of the lower supporting plate 445 are provided with limit cards 448, and the limit cards protrude out of the upper end face of the lower supporting plate 445.

The working principle is as follows: in production, when a product box to be packaged is fed into the lower die assembly, the product box is placed on the lower carriage 445, and when the upper die and the lower die are combined, the lower carriage descends to load the outer edge port of the product box onto the die orifice of the lower die cavity 443. After the upper die set and the lower die set are closed, a heat-sealing film is covered on the surface of a product box to be packaged, a relative seal is formed between the lower panel 442 and the upper pressure plate 435 of the upper die assembly, a vacuum groove 446 is formed in the periphery of the lower cavity 443 and connected with a vacuum pump, and after the vacuum pump works, the vacuum groove is vacuumized, so that air in the product box is pumped out, and the product box is in a negative pressure state. Then the jacking mechanism jacks the lower die assembly upwards, and at the same time, the heating ring 438 on the upper die assembly 43 works to heat the heat-sealing film and then adhere the heat-sealing film to the upper edge of the product box, so that the heat-sealing of the product box is realized. Then, the lifting mechanism continues to rise, and the cutter ring 439 mounted on the outer contour of the upper heating plate 437 is forced to move downwards, so that the heat-sealing film is cut off, and the heat-sealing film is separated from the product box. After the jacking mechanism is reset, the heat sealing is completed, the lower carriage is reset upwards, and the product box after the heat sealing is completed is lifted upwards, so that the main body of the product box is higher than the lower die assembly.

In order to ensure that the sealing performance between the die and the product box is better and the pressure is more uniform and stable when the die is subjected to heat sealing and pressing, a support ring is arranged on the outer contour of the lower cavity 443 in the scheme, and a sealing ring 447 is covered on the surface of the support ring. The sealing ring plays a role in bearing the product box, and when the upper die and the lower die are closed, the elastic support of the sealing ring 447 is utilized, so that the heat sealing film and the product box are in an elastic compression state, and the sealing performance of the product box is ensured.

Wherein, in order to make things convenient for the mould in the present case can match the manipulator, realizes automatic unloading of going up, and the middle part fretwork of lower die cavity 443 in the present case forms lifting area 444, installs bottom plate 445 in the lifting area 444 and is connected with lower climbing mechanism 5, and lower climbing mechanism 5 can be before the product packaging and pack the back upwards jack-up packing carton, makes to have certain clearance between its edge and the lower mould to make things convenient for the manipulator anchor clamps to press from both sides and get. And in the heat sealing process, the lower jacking mechanism 5 drives the lower supporting plate to move downwards, so that the edge of the packaging box can be supported on the sealing ring.

Compared with the prior art, the mould in the present case can realize that the automation of product box is managed to find time, and automatic heat-seal has easy operation, and is high-efficient convenient, avoids manual operation error and the sealed advantage such as not tight that takes place, so can extensively use widely.
