Description

Technical Field

[0001] The invention belongs to the technical field of packaging equipment, and in particular relates to a side air intake type air column packaging automatic inflator. Background Art

[0002] Side-inlet air column packaging is an innovative packaging technology that is mainly used to provide cushioning protection for products, especially during transportation. This packaging method uses natural air to fill the air column to form a soft but effective protective layer, which can significantly reduce the risk of damage to the product due to vibration or impact. The side-inlet design makes the inflation process more convenient and efficient. Users only need to insert the inflation tube into the designated air inlet and then perform the inflation operation. This design not only saves time, but also reduces the risk of air bag damage caused by improper operation, and makes the entire packaging process more labor-saving.

[0003] The Chinese patent document with publication number CN216100681U discloses an inflation device for the production of cushioning packaging bags, including a box body, an inflation device, a track, a clamping assembly and a box door. The upper surface of the box body is provided with an inflation device and a track, the inflation device and the track are respectively fixedly connected to the box body, and a box door is provided on the front of the box body, the box door is rotatably connected to the box body through a fixed shaft, the clamping assembly is divided into four groups, and the four groups of clamping assemblies are respectively used in conjunction with the tracks. By adding a clamping assembly to this device, the device can clamp the cushioning packaging bag, thereby reducing manpower. The staff only needs to place the cushioning packaging bag between the two groups of clamping plates. Through the spring, the two groups of clamping plates can tightly clamp the cushioning packaging bag. When the cushioning packaging bag is inflated, the staff can remove it again, which can effectively improve the work efficiency, thereby improving the staff's use experience.

[0004] In the above patent scheme, it is necessary to manually hold the packaging bag, place it on the clamping device and fix it, insert the inflation device into the inflation port for inflation, and manually remove the inflated packaging bag. The operation steps of the clamping assembly and the inflation process after clamping need to be accurately operated manually, and the operation steps are cumbersome, and the operation cycle of a single packaging bag is long. Summary of the invention

[0005] In order to overcome the technical problems in the prior art that the side-inlet type air column package needs to be manually clamped and positioned, and the inflation device needs to be manually operated to align with the inflation port for inflation, resulting in a long inflation cycle for a single side-inlet type air column package and low working efficiency; one purpose of the present invention is to provide an automatic inflator for side-inlet type air column package, by using a rubber ring to press the inflatable package onto a chassis, and the air outlet holes in the rubber ring release air to increase the air pressure in the rubber ring, thereby causing the lower end film of the air column package inflation port to be recessed into the long groove on the chassis, forming an inflation passage for inflating the inflatable package, without the need for clamping and manual alignment with the inflation port for inflation, which is simple and convenient.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a side-inlet type air column packaging automatic inflator, comprising a chassis, a pressure plate longitudinally slidably connected to the chassis, and two rubber rings arranged at the lower end of the pressure plate; wherein, the lower end of the pressure plate is provided with two air outlet holes connected to the compressor, and the two air outlet holes are respectively located in the two rubber rings; the upper end of the chassis is provided with two long grooves, one end of the long groove is opposite to the interior of the rubber ring, and the other end is located on the outside of the rubber ring; the rubber ring can selectively press the air column package tightly against the upper end of the chassis, and the two inflation ports of the air column package are respectively located in the two rubber rings.

[0007] When the rubber ring is located at the lower extreme position, the rubber ring seals the air column package tightly against the upper end of the chassis, and the air outlet increases the air pressure in the rubber ring, so that the film at the lower end of the inflation port of the air column package is pressed into the long groove by the air pressure to form an inflation passage, and the continuously delivered compressed air enters the air column package through the inflation passage to realize the inflation process.

[0008] Furthermore, two positioning holes are provided through one end of the air column package near the inflation port; at least two array holes are provided on the upper end of the chassis, and the array holes are located between the two long grooves; wherein, positioning pins are detachably connected to the two array holes respectively; and the two positioning pins are respectively opposite to the two positioning holes.

Therefore, the air pressure requirements of the two inflatable units are different. The two hand-pull valves control the order of inflation of the two inflatable units, and the time relay controls the inflation interval of the two inflatable units.

[0014] Specifically, the cover shell includes a first cover shell arranged at the upper end of the chassis and a second cover shell arranged on the side of the first cover shell facing the long groove; the second cover shell is located directly above the long groove; a cylinder is arranged at the lower part of the second cover shell; and the pressure plate is arranged on the moving end of the cylinder.

[0015] Furthermore, an L-shaped plate is arranged at the upper end of the chassis, and a sensor is horizontally arranged on the L-shaped plate; the detection end of the sensor is directly opposite to the area directly below the pressure plate.

[0016] The sensor is used to prevent the pressing plate from being pressed down due to misoperation or accident when operating the air column package, thereby causing harm to the user.

[0017] Optionally, two parallel adjustment grooves are provided at the lower end of the L-shaped plate; and the detection direction of the sensor is parallel to the arrangement direction of the two rubber rings.

[0048] When hand-pull valve A and hand-pull valve B are pressed at the same time, relay A controls solenoid valve A to discharge air → solenoid valve A discharges air to hand-pull valve A → then L1 air blowing pipe is connected, correspondingly, air is discharged from the left air outlet first, after a delay, relay B is connected → solenoid valve B is connected → hand-pull valve B → R1 air blowing pipe blows air, correspondingly, air is discharged from the right side, that is, when the two hand-pull valves are pressed at the same time, air is discharged from the left side first after a delay and then simultaneously.

[0049] When hand-pull valve A and hand-pull valve B are pulled up at the same time, relay A controls solenoid valve A to discharge air → solenoid valve A discharges air to hand-pull valve A → R2 air blowing pipe blows air, which corresponds to the right air outlet first. After a delay, relay B controls solenoid valve B to discharge air → solenoid valve B discharges air to hand-pull valve B → L2 air blowing pipe blows up, which corresponds to the left air outlet. That is, when the two hand-pull valves are pulled up at the same time, the right air outlet is first and then both air outlets are simultaneously discharged.
