Description

Technical Field

[0001] The utility model belongs to the technical field of bubble bag production, and particularly relates to a transmission device for detecting air leakage of bubble bags. Background Technique

[0002] Bubble bags, also known as air cushion films, air bead adhesives, bubble rolls, etc., are a widely used packaging material. With the rapid development of e-commerce, the demand in the express delivery industry has been increasing year by year. As an important part of express packaging, bubble bags have become an indispensable part of industries such as e-commerce and logistics with their unique cushioning and protective properties. Currently, the bubble bag market is in a situation of supply falling short of demand, and the future market prospect is broad.

[0003] In the production process of bubble bags, a common challenge is that bubble bags may be damaged or air leak. This is directly related to the product quality and protection efficiency. Traditional methods for detecting air leakage of bubble bags often rely on manual visual inspection. This method is not only inefficient but also easily affected by human factors, resulting in missed inspections or false inspections occurring frequently, and it is difficult to meet the requirements of large-scale bubble bag production. Content of the Utility Model

[0004] The purpose of the utility model is to provide a transmission device for detecting air leakage of bubble bags, which can prompt the staff whether the bubble bag leaks air, has good detection effect, further improves the detection efficiency, reduces the labor intensity, and can adapt to the production of large quantities of bubble bags.

[0005] The technical solution adopted by the utility model is specifically as follows:

[0006] A transmission device for detecting air leakage of bubble bags includes a detection box. On both sides of the top of the detection box, first conveyor rollers are rotatably installed. Inside the detection box, two partition plates are fixed. There is a gap between the bottom of the partition plate and the inner bottom wall of the detection box. A second conveyor roller is rotatably installed at the bottom of the partition plate. A grid frame plate is fixed between the two partition plates, and pressure sensors are arranged in the grids on the grid frame plate.

[0007] Further, a sloping plate is fixed on one side of the top of the detection box. On one side of the top of the sloping plate, a drying box is arranged. On one side of the drying box, a single-chip microcomputer controller electrically connected to the pressure sensor is arranged.

[0008] Further, an alarm electrically connected to the single-chip microcomputer controller is arranged on one side of the detection box.

[0009] Further, a unwinding mechanism is arranged on the outside of one side of the detection box, and a winding mechanism is arranged on the outside of one side of the drying box.

[0010] Further, an observation window is provided on one side of the detection box, and the glass of the observation window is made of convex mirror glass.

[0011] Further, mounting rods are fixed on both sides of the top of the inclined plate. A first arc-shaped rod is slidably mounted between the outer walls of the two mounting rods. A spring is provided on the outer wall of the mounting rod and above the first arc-shaped rod. A second arc-shaped rod is fixed between the outer walls of the two mounting rods and below the first arc-shaped rod. Rubber scraping blades in contact with each other are provided on the outer walls of the second arc-shaped rod and the first arc-shaped rod.

[0012] The technical effects achieved by the present utility model are as follows:

[0013] For the transmission device for detecting air leakage of bubble bags of the present utility model, the provided detection box immerses the bubble bags in water. When the bubble bags move between the two partition plates, the bubbles generated by air leakage flow through the squares on the grid frame plate and are detected by the pressure sensor. The detected signal is transmitted to the single-chip microcomputer controller, and the single-chip microcomputer controller controls the alarm to start, prompting the staff whether the bubble bags are leaking air. The detection effect is good, which further improves the detection efficiency, reduces the labor intensity, and can adapt to the production of a large number of bubble bags.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0020] Such as Figures 1-3As shown in the figure, a transmission device for detecting air leakage of bubble bags includes a detection box 1. On both sides of the top of the detection box 1, first conveyor rollers 2 are rotatably installed. Inside the detection box 1, two partition plates 3 are fixed. There is a gap between the bottom of the partition plate 3 and the inner bottom wall of the detection box 1. A second conveyor roller 4 is rotatably installed at the bottom of the partition plate 3. A grid frame plate 5 is fixed between the two partition plates 3. Pressure sensors 6 are arranged in the grids on the grid frame plate 5. When a bubble passes through the liquid flowing over the pressure sensor 6, it will cause an instantaneous change in pressure. The pressure sensor 6 can identify the bubble by monitoring these pressure changes. The arranged partition plate 3 prevents the bubble bag from making a large noise when entering the water, affecting the detection of the pressure sensor 6. The structure is simple, the operation is convenient, the detection effect of the bubble bag air leakage is good, and the staff can intuitively observe the air leakage place of the bubble bag, improving the detection effect and efficiency;

[0021] As Figures 1-2 shown, on one side of the top of the detection box 1, an inclined plate is fixed. On one side of the top of the inclined plate, a drying box 10 is arranged. The arranged drying box 10 is a prior art. For the specific structure and working principle, please refer to the Chinese patent of a bubble bag and its air leakage detection process with the publication number CN 116812340 A. This drying box 10 is not within the protection scope of this application either, so it will not be described in detail. On one side of the drying box 10, a single-chip microcomputer controller 11 electrically connected to the pressure sensor 6 is arranged;

[0022] As Figure 1 shown, on one side of the detection box 1, an alarm 8 electrically connected to the single-chip microcomputer controller 11 is arranged. When the pressure sensor 6 detects a signal and transmits it to the single-chip microcomputer controller 11, the single-chip microcomputer controller 11 controls the alarm 8 to start, playing a prompting role and facilitating the staff to timely discover the air leakage place;

[0023] As Figures 1-2 shown, on the outside of one side of the detection box 1, a unwinding mechanism 12 is arranged. On the outside of one side of the drying box 10, a winding mechanism 13 is arranged. The unwinding mechanism 12 and the winding mechanism 13 are both composed of brackets and rollers, and on one side of the winding mechanism 13, a motor connected to the roller is arranged, making the equipment relatively perfect and facilitating the movement of the bubble bag;

[0024] As Figure 1 shown, on one side of the detection box 1, an observation window 7 is arranged. The glass of the observation window 7 uses convex mirror glass, which is convenient for clearly observing the internal situation of the detection box 1 and is relatively practical;

[0025] As Figures 1-2As shown in the figure, mounting rods 14 are fixed to both sides of the top of the inclined plate. A first arc-shaped rod 16 is slidably mounted between the outer walls of the two mounting rods 14. A spring 15 is arranged on the outer wall of the mounting rod 14 and above the first arc-shaped rod 16. A second arc-shaped rod 17 is fixed between the outer walls of the mounting rods 14 and below the first arc-shaped rod 16. Rubber scraping blades 18 which are in contact with each other are arranged on the outer walls of the second arc-shaped rod 17 and the first arc-shaped rod 16, which can scrape the moisture on the surface of the bubble bag and improve the subsequent drying efficiency of the bubble bag.

[0026] The working principle of the present utility model is as follows: When in use, the detection box 1 is placed in water, and the water level added should be above the grid frame plate 5. The bubble bag roll is placed on the unwinding mechanism 12, and the other end passes under the two partition plates 3, then passes between the two rubber scraping blades 18, and then passes through the air drying box 10 and is finally fixed on the winding mechanism 13. The motor drives the winding mechanism 13 to rotate and drives the bubble bag to move. When the bubble bag has air leakage, when the bubble bag returns to the bottom of the detection box 1, it causes bubbles in the water. The bubbles rise and flow through the grids on the grid frame plate 5 and are detected by the pressure sensor 6. The detection signal is transmitted to the single-chip microcomputer controller 11, and the single-chip microcomputer controller 11 controls the alarm 8 to start, enabling the staff to make a response. The observation window 7 is provided to facilitate observing the situation of the bubble bag in the detection box 1.

[0027] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in this field.
