Technical Field
The invention belongs to the technical field of inflatable packaging, and particularly relates to an automatic opening device for an air channel opening of an air column packaging body.
Background
The air column packaging body is a buffering packaging material with a reverse air stop valve, two layers of films form a plurality of independent air columns under the hot pressing of a specific grinding tool, each air column is provided with an air valve (a one-way valve or a reverse air stop valve), all the air columns share one inflation inlet, the air columns are stored and transported in a flat film shape before use, the air columns are inflated immediately, and the air valves can automatically lock air after inflation, so that the inflation air pressure can be adjusted as required.
However, the reverse air stop valve is sealed and locked by the self-adhesion between films, and is not like a locking mode such as heat sealing or adhesion, and the air pressure in the air column is greatly reduced within one or two months, so that the protection is greatly reduced, and therefore, the air column packaging body is only used in short-distance and short-time express delivery or logistics transportation. In addition, the current inflation mode of the air column packaging body with the one-way air stop valve can be manual inflation or automatic inflation, manual inflation needs manual air nozzles to be aligned to air channel openings for inflation, and the manual inflation is flexible, but low in efficiency and unstable in manual inflation quality.
At present, the automatic inflator carries out automatic inflation to the gas column packing body of rolling up membrane form, but can cut the air flue after aerifing, otherwise can't take out the gas column packing body after aerifing, and this also leads to can't carrying out the heat-seal to the gas channel mouth again and seals, consequently, because the air flue cuts the back, and the membrane of air flue has already the fold uneven, not only pleasing to the eye, and the lock gas effect is poor moreover.
In order to improve the reliability of the heat sealing of the air column packaging body and avoid the operations such as air flue cutting, and the like, the air is filled into an inner cavity from an inlet (an air flue opening) of the air flue, the air can be filled into each air column through a one-way valve, after the air filling is finished, the air flue opening is subjected to heat sealing, and a long-time air locking effect can be achieved, so that the air column packaging body is used for long-time storage and transportation scenes (such as packaging of express delivery or logistics), however, because the air flue opening is formed by two layers of films (generally, the films are attached to each other), if the air filling is needed, the two layers of films are firstly relatively opened, and then the inflating nozzle is inserted, so that the air filling can be implemented, and in the actual operation, the following defects exist during the opening and the inflating of the air flue opening:
1. the two layers of films are viscous, so that the films are difficult to separate, the inflation efficiency is low, and meanwhile, the deformation of the films is difficult to avoid in the opening process, so that the later-stage heat sealing qualification rate is low, and the air locking effect is poor;
2. after the air passage opening, because the inner diameter of the air passage opening is certainly larger than the outer diameter of the inflating nozzle, when quantitative inflation is carried out, partial air leaks from the inflating nozzle to the air passage opening, so that the internal inflating quantity or the inflating air pressure of the air column packaging body is insufficient.

Specifically, the lower mold 1 includes a lower mold body 10 having an internal vacuum pumping cavity, and a lower mold sleeve 11 sleeved on the lower mold body 10.
A lower arc-shaped groove 100 which is recessed inwards from the top surface is formed on the lower die body 10, and the lower die sleeve 11 is a flexible sleeve which closes the lower arc-shaped groove 100 to form a lower deformation cavity q1.
A plurality of adsorption holes x1 are formed on the lower arc-shaped groove 100, and air holes x2 are formed at the parts of the lower die sleeve 11 corresponding to the lower arc-shaped groove 100.
Specifically, the lower arc-shaped slot 100 is semicircular.
As shown in fig. 4, a plurality of adsorption holes x1 are distributed in an array around the semicircular groove surface.

The vacuum adsorption component 4 comprises a vacuum-pumping interface 40, a vacuum-pumping pump and a vacuum-pumping pipe which are positioned at the same end and respectively communicated with the vacuum-pumping cavities of the upper die 2 and the lower die 1.
As shown in fig. 6, after the air vent of the air column package body moves to the inflation and sealing station, the lower film of the air vent is attached to the lower mold sleeve 11 of the lower mold 1 and seals the air vent x2, the upper mold 2 moves downward to attach, so that the upper mold sleeve 21 and the lower mold sleeve 11 are pressed to the air vent, and the upper film of the air vent is attached to the upper mold sleeve 21 of the upper mold 2 and seals the air vent x2, at this time, the vacuum adsorption component 4 provides negative pressure, and during the upward movement of the upper film m1 and the downward movement of the lower film m2, the portions at the two sides of the air vent move inward gradually along the compression joint formed by the flexible modules to open the air vent k. Therefore, the membrane larger than the outer diameter part of the inflating nozzle is positioned in the pressure joint formed by the flexible modules, and the probability of inflation leakage is further reduced.

Due to the arrangement, the flexible sleeve and the upper layer film m1 are kept attached, and the opening of the airway opening k is facilitated.
Of course, there is a case where the air holes x2 are correspondingly communicated with the adsorption holes x1, and at this time, the adsorption force is provided maximally.
In addition, the inflation end part 50 of the inflation nozzle 5 is in a frustum shape, when inflation is completed, the vacuum pumping cavity gradually releases negative pressure, the flexible sleeve is attached and reset, the inflation nozzle 5 is extruded out of the air passage opening k, and the upper film m1 and the lower film m2 are relatively flattened and closed synchronously. That is to say, the effect of flexible cover not only plays laminating diaphragm and forms flexible sealed effect with the charging connector, but also can with the charging connector cooperation in order to implement upper and lower tunic flattening and sealing.
Furthermore, the inflating nozzle comprises a cylindrical body and an inflating end part formed at the inserting end part of the cylindrical body, wherein the inflating end part is in a conical shape or a frustum shape, and the upper layer film and the lower layer film are relatively pressed and sealed at the periphery of the cylindrical body during inflation; when the inflation is finished, the vacuum pumping cavity gradually releases negative pressure, the air nozzle is actively pumped out, the flexible sleeve is attached and reset, the air nozzle is extruded out of the air channel opening, and the upper film and the lower film are relatively flattened and closed.
