Technical Field

[0002] With the rapid development of the modern packaging industry, packaging materials such as soft bags are widely used in food, medicine, chemical and daily necessities industries due to their lightness, durability and plasticity. The sealing performance of soft bags is directly related to the quality of the product. For example, when liquid is placed in a soft bag, if the soft bag is not sealed well, it is easy to cause the liquid in the soft bag to leak. Therefore, the sealing test of soft bags is particularly important.

[0003] In the related art, a non-leaking soft bag is selected as a standard soft bag in advance, and a detection device is used to detect the pressure value of the standard soft bag, which is recorded as the standard pressure value. When testing the produced soft bags, the soft bag is first squeezed by the squeezing device, and then the detection device detects the pressure value of the squeezed soft bag, and the detected pressure value is compared with the standard pressure value to determine whether the tested soft bag is leaking.

[0004] However, in actual production, there are certain differences between soft bags produced in different batches, which affects the test results and the test accuracy. If the standard pressure value is measured for each batch of soft bags, the test efficiency will be affected. Summary of the invention

[0039] refer to Figure 1 and Figure 4 An extrusion channel is formed between the extrusion belt 513 and the belt of the transport mechanism 2. The extrusion belt 513 and the belt of the transport mechanism 2 move in the same direction and at the same speed, so that the soft bag passes through the extrusion channel. When the soft bag passes through the extrusion channel, under the elastic force of the elastic member 524, the extrusion pressing block 523 applies an extrusion force to the soft bag, which can accelerate the leakage speed of the damaged soft bag.

[0040] refer to Figure 1 The second inspection station 6 has the same mechanism as the first inspection station 4, and can detect the pressure value of the soft bag. The height adjustment component 3 makes the first inspection station 4 and the second inspection station 6 have the same distance from the transportation mechanism 2, that is, the first inspection station 4 and the second inspection station 6 have the same squeezing force on the soft bag, which is conducive to comparing the changes in the pressure value before and after squeezing, so as to determine whether the soft bag is leaking.

[0042] The implementation principle of a soft bag leak detection and rejection device in Example 1 of the present application is as follows: the conveyor belt 41 and the transport mechanism 2 are abutted to allow the soft bag to pass through the feed channel, the soft bag squeezes the force measuring pulley 422, and the pressure sensor 423 detects the pressure value of the soft bag. Then, the conveyor belt 51 and the transport mechanism 2 are squeezed to allow the soft bag to pass through the extrusion channel, and the elastic member 524 pushes the extrusion block 523 to apply extrusion force to the soft bag. The second inspection station 6 detects the pressure value of the soft bag again, and compares the pressure value of the soft bag before and after extrusion to determine whether the current soft bag is leaking. Finally, the rejection drive source 71 pushes the leaking soft bag into the drop bin 73 through the push plate 72 to achieve the rejection of defective products.

[0043] Embodiment 2: Embodiment 2 of the present application provides a soft bag leak detection and rejection device.

For the extrusion stations 5 on both sides, the moving directions of the extrusion belts 513 are opposite, so that the soft bag rotates on the horizontal plane.

[0044] In the present application, for the contact area between the extrusion belt 513 and the soft bag, if the damaged area of ​​the soft bag is located in the contact area, the extrusion belt 513 will block the damaged area of ​​the soft bag to a certain extent, which may cause the soft bag to leak slowly and it is difficult to produce obvious volume changes, which is not conducive to subsequent detection and comparison. The extrusion station 5 located on both sides of the transport mechanism 2 allows the product to rotate on the transport mechanism 2, which can make the extrusion belt 513 contact different areas of the soft bag, which is conducive to the leakage of the damaged soft bag.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
