Description

Technical Field

[0001] This utility model belongs to the field of packaging machinery technology, and in particular relates to an air-leakage-proof sealing nozzle for e-commerce bubble wrap inflators. Background Technology

[0002] An e-commerce bubble wrap inflator is an automated device used to produce bubble wrap packaging materials, primarily for e-commerce logistics and product transportation. Its core function is to inject air into a double-layered plastic film via an inflation system, forming a cushioning bubble structure to protect goods from impacts during transport.

[0003] Traditional bubble wrap inflators typically use a single inflation nozzle. When the nozzle becomes clogged, leaks, or has insufficient air pressure, it can lead to uneven inflation of the bubble wrap, or even complete failure to inflate, affecting production efficiency and causing material waste. Manual intervention is required when the nozzle malfunctions, as it cannot automatically switch to a backup nozzle. To address these issues, we offer leak-proof sealing nozzles for e-commerce bubble wrap inflators. Utility Model Content

[0004] The purpose of this utility model is to provide a leak-proof sealing nozzle for an e-commerce bubble wrap inflator. By coordinating the adjustment mechanism and the detection mechanism, it solves the problem in the existing bubble wrap inflator nozzles that cause uneven inflation of the bubble wrap, or even complete failure to inflate, thus affecting production efficiency, when the nozzle is blocked, leaks air, or has insufficient air pressure.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to an air-tight sealing nozzle for an e-commerce bubble wrap inflator, comprising an inflation box, an inflation pipe connected to the front of the inflation box, an inflation nozzle connected to the surface of the inflation pipe, an adjustment mechanism inside the inflation pipe, the adjustment mechanism comprising a sealing plate disposed inside the inflation pipe, a push plate fixedly connected to one side of the sealing plate, and a push block fixedly connected to one side of the push plate, a detection mechanism disposed on the top of the inflation box, a detection plate disposed on the top of the detection mechanism, a pressure sensor fixedly connected to the bottom of the detection plate, a pulley disposed at the bottom of the detection plate, and a contact rod fixedly connected to the top of the pulley.

[0007] The present invention is further configured such that the number of the inflation nozzles is four, and the surface of the sealing plate is provided with two ventilation holes, which are staggered.

[0008] The present invention is further configured such that a pushing groove adapted to the pushing block is opened on the surface of the inflation tube, and a sliding cylinder is fixedly connected to the side of the pushing block away from the pushing plate, and the sliding cylinder is fixedly connected inside the inflation box.

[0009] The present invention is further configured such that the sealing plate and the pushing plate are both coaxial annular plate structures, and the sealing plate and the pushing plate cooperate to form a hollow cavity assembly.

[0010] The present invention is further configured such that the pressure sensor and the contact rod are designed on the same axis, and the pulley is located on the front side of the inflation tube.

[0011] The present invention is further configured such that a vertical rod is fixedly connected to the top of the pulley, and a spring is sleeved on the surface of the vertical rod.

[0012] The present invention is further configured such that a sliding through hole is provided inside the detection plate, and an anti-detachment plate is provided on the top of the detection plate.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model achieves automatic and seamless switching in case of nozzle failure by using two sets of alternating inflation nozzles and a sealing plate switching mechanism driven by a slide cylinder. When the detection mechanism detects inflation failure, the adjustment mechanism can switch to the backup inflation nozzle, ensuring zero production interruption. Compared with the traditional single-nozzle design, this solution reduces downtime due to malfunctions, making it particularly suitable for high-intensity production scenarios such as e-commerce logistics.

[0015] 2. This invention utilizes a pulley-spring buffer system to monitor the bubble wrap inflation status in real time, and a pressure sensor to accurately report pressure changes. Combined with a hollow cavity assembly formed by a coaxial annular sealing plate and a pusher plate, gas leakage is effectively prevented. This dual protection improves the bubble wrap inflation pass rate, reduces material waste, and lowers production costs.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figures 1-5 This utility model is a leak-proof sealing nozzle for an e-commerce bubble wrap inflator, including an inflation box 1, an inflation pipe 2 connected to the front of the inflation box 1, an inflation nozzle 3 connected to the surface of the inflation pipe 2, an adjustment mechanism inside the inflation pipe 2, the adjustment mechanism including a sealing plate 4 inside the inflation pipe 2, a push plate 5 fixedly connected to one side of the sealing plate 4, and a push block 6 fixedly connected to one side of the push plate 5, a detection mechanism on the top of the inflation box 1, a detection plate 7 on the top of the detection mechanism, a pressure sensor 8 fixedly connected to the bottom of the detection plate 7, a pulley 9 at the bottom of the detection plate 7, and a contact rod 10 fixedly connected to the top of the pulley 9.

[0027] Specifically: By adjusting the mechanism settings, rapid switching and airflow control of the inflation nozzles 3 are achieved, ensuring seamless switching to backup nozzles in case of nozzle failure and avoiding production interruptions. The staggered ventilation holes 11 on the sealing plate 4 divide the four inflation nozzles 3 into two groups (nozzles 1 and 3, and nozzles 2 and 4). When one group of nozzles becomes blocked or leaks air, the slide cylinder 12 drives the push block 6 to move, adjusting the position of the sealing plate 4 and switching the airflow to the other group of nozzles, achieving zero-downtime switching. The sealing plate 4 and the push plate 5 form a coaxial annular hollow cavity, ensuring the airflow channel is sealed. The push plate 5 simultaneously closes the push channel during movement to prevent gas leakage. The detection mechanism monitors the inflation status in real time and triggers fault response to ensure the inflation quality of the bubble film. The contact rod 10 moves with the surface of the bubble film and judges whether the inflation is sufficient by the pressure change. When inflation failure is detected, the pressure sensor 8 sends a signal to the control system to trigger the adjustment mechanism to switch the nozzle group. Through the coordinated design of the adjustment mechanism and the detection mechanism, the problems of low reliability, high failure rate and high maintenance cost of traditional air inflators are solved, which is especially suitable for high-efficiency scenarios such as e-commerce logistics.

[0028] Example 2

[0029] Please see Figures 1-5 Based on Example 1, the number of inflation nozzles 3 is four, the surface of the sealing plate 4 is provided with two ventilation holes 11, and the two ventilation holes 11 are staggered. The surface of the inflation tube 2 is provided with a pushing groove that matches the pushing block 6. The side of the pushing block 6 away from the pushing plate 5 is fixedly connected to a sliding cylinder 12, which is fixedly connected inside the inflation box 1. The sealing plate 4 and the pushing plate 5 are both coaxial circular plate structures. The sealing plate 4 and the pushing plate 5 cooperate to form a hollow cavity assembly. The pressure sensor 8 and the contact rod 10 are designed on the same axis. The pulley 9 is set on the front side of the inflation tube 2. The top of the pulley 9 is fixedly connected to a vertical rod 13. The surface of the vertical rod 13 is fitted with a spring 14. The inside of the detection plate 7 is provided with a sliding through hole. The top of the detection plate 7 is provided with an anti-detachment plate 15. The vertical rod 13 is located inside the sliding through hole. The anti-detachment plate 15 is fixedly connected to the top of the vertical rod 13.

[0030] Specifically: Through the staggered design of the ventilation holes 11, two inflation nozzles 3 can be staggered to connect, allowing the four inflation nozzles 3 to spray gas in the order of first and third, and second and fourth. If one set of inflation nozzles 3 fails to inflate, another set of inflation nozzles 3 can be used for inflation in a timely manner. The setting of the push channel allows the push block 6 to have moving space, thereby driving the push plate 5 to move. At the same time, the push plate 5 can seal the push channel during use to prevent air leakage. Through the setting of the sealing plate 4 and the push plate 5, the position of the sealing plate 4 can be adjusted by the push plate 5. The setting of the hollow cavity assembly allows the airflow to pass smoothly and flow to the inflation nozzles 3. Through the setting of the pressure sensor 8 and the contact rod 10, the pressure change is used to detect whether the bubble film has been inflated. Through the setting of the vertical rod 13 and the spring 14, the pulley 9 can move up and down following the curve of the bubble film.

[0031] The working principle of this utility model is as follows: When the air inflator is working normally, the slide cylinder 12 is in the initial position, the air passage 11 of the sealing plate 4 is connected to the first set of air inflator nozzles 3 (first and third air inflator nozzles 3), and the gas enters the corresponding air inflator nozzle 3 through the hollow cavity assembly to complete the inflation.

[0032] At this time, the pulley 9 of the detection mechanism is in contact with the inflated bubble film, and the pressure sensor 8 receives the stable pressure signal transmitted by the contact rod 10. When the inflation nozzle 3 is blocked or leaks, the surface of the uninflated bubble film is depressed, and the pulley 9 is pressed down by the spring 14, causing the contact rod 10 to move. After the pressure sensor 8 detects the abnormal pressure value, it sends an electrical signal to the control system, which triggers the PLC controller to control the start of the slide cylinder 12.

[0033] The sliding cylinder 12 then pushes the push block 6 to move laterally, causing the sealing plate 4 to move and switch the vent hole 11 to the corresponding position of the second set of inflation nozzles 3 (the second and fourth inflation nozzles 3). During this process, the push plate 5 simultaneously closes the push groove, and the vent hole 11 of the sealing plate 4 and the standby inflation nozzles 3 form a sealed air path, achieving uninterrupted switching. At the same time, the annular hollow cavity structure maintains the continuity of airflow, ensuring stable inflation pressure of the bubble film.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
