Description

Technical Field

[0001] The present application relates to the technical field of bag detection, and in particular to a soft bag leak detection and rejection device. Background Art

[0002] With the rapid development of the modern packaging industry, flexible bags and other packaging materials are widely used in industries such as food, pharmaceuticals, chemicals, and daily necessities due to their lightness, durability, and plasticity. The sealing performance of flexible bags is directly related to product quality. For example, if a flexible bag is not properly sealed, the liquid inside can easily leak. Therefore, the sealing performance of flexible bags is particularly important.

[0003] In related technologies, a non-leaking soft bag is pre-selected as a standard soft bag. A detection device is used to detect the pressure applied to the standard soft bag and record the pressure as the standard pressure value. When testing the produced soft bags, the bag is first squeezed using a squeezing device. The detection device then detects the pressure applied to the squeezed soft bag. The detected pressure value is then compared with the standard pressure value to determine whether the tested soft bag is leaking.

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

[0005] In order to improve the detection accuracy of soft bags and improve the detection efficiency, the present application provides a soft bag leak detection and rejection device.

[0006] This application provides a soft bag leak detection and rejection device, which adopts the following technical solutions:

[0008] frame;

[0012] The second inspection station is set on the frame. The product passes through the first inspection station, the extrusion station and the second inspection station in sequence. The second inspection station has the same structure as the first inspection station. The second inspection station detects the pressure value of the product when passing through.

[0013] By employing this technical solution, the transport mechanism moves the product.

[0065] refer to Figure 1 and Figure 2The height adjustment assembly 3 includes a support frame 31, a connecting block 32, a screw 33, an adjusting hand wheel 34, a height scale 35 and an indicating ruler 36.

[0066] refer to Figure 2 and Figure 3 The first inspection station 4 includes an abutment conveyor belt 41 and a force measuring assembly 42. The abutment conveyor belt 41 includes a bearing seat 411, an abutment pulley 412, an abutment belt body 413 and a rotation drive source 414. The connecting block 32 of the height adjustment assembly 3 corresponding to the first inspection station 4 is fixedly connected to the bearing seat 411, and the abutment pulley 412 is rotationally connected to the bearing seat 411. There are multiple abutment pulleys 412, and the abutment belt body 413 is sleeved on the multiple abutment pulleys 412.

The rotation drive source 414 can drive the abutment pulley 412 to rotate, and the abutment pulley 412 causes the abutment belt body 413 to move.

[0067] refer to Figure 2 and Figure 3 A conveying channel is formed between the abutting belt 413 and the conveying mechanism 2. The abutting belt 413 and the belt of the conveying mechanism 2 move in the same direction and at the same speed, allowing the soft bags to pass through the conveying channel. The abutting belt 413 and the conveying mechanism 2 can provide a certain amount of squeezing force on the soft bags. The height adjustment assembly 3 can adjust the distance between the first inspection station 4 and the conveying mechanism 2, that is, it can adjust the size of the conveying channel, thereby adjusting the squeezing force on the soft bags.

[0068] refer to Figure 3 The force measuring assembly 42 includes an auxiliary pressure wheel 421, a force measuring pulley 422, and a pressure sensor 423. The auxiliary pressure wheel 421 is rotatably connected to the support base 411, the pressure sensor 423 is fixedly connected to the support base 411, and the force measuring pulley 422 is rotatably connected to the pressure sensor 423.

There are multiple auxiliary pressure wheels 421, each located on either side of the force measuring pulley 422.

[0069] refer to Figure 2 and Figure 3A detection gap is formed between the force measuring pulley 422 and the transport mechanism 2. When the soft bag moves to the detection gap in the feeding channel, multiple auxiliary pressure wheels 421 apply pressure to both ends of the soft bag, causing the middle part of the soft bag to bulge. The force measuring pulley 422 is squeezed by the middle part of the soft bag, which is conducive to the pressure sensor 423 detecting the pressure value, and the pressure value is recorded as the initial pressure value.

[0070] refer to Figure 1 and Figure 4 The extrusion station 5 includes an extrusion conveyor belt 51 and an extrusion assembly 52. ​​The extrusion conveyor belt 51 includes a support base 511, an extrusion pulley 512, an extrusion belt body 513, a rotational drive source 514, and an extrusion assembly 52. ​​The connecting block 32 of the height adjustment assembly 3 corresponding to the extrusion station 5 is fixedly connected to the support base 511. The extrusion pulley 512 is rotationally connected to the support base 511. There are multiple extrusion pulleys 512, and the extrusion belt body 513 is sleeved on multiple extrusion pulleys 512. The rotational drive source 514 is specifically a motor. The rotational drive source 514 is fixedly connected to the support base 511. The rotational drive source 514 drives the extrusion pulley 512 to rotate, and the extrusion pulley 512 causes the extrusion belt body 513 to move.

[0071] refer to Figure 4 and Figure 5 The extrusion assembly 52 includes a support base 521, a guide rod 522, an extrusion pressing block 523, and an elastic member 524. The support base 521 is fixedly connected to the support seat 511, and the guide rod 522 passes through the support base 521. The guide rod 522 is slidably connected to the support base 521. The extrusion pressing block 523 is fixedly connected to the guide rod 522, and the extrusion pressing block 523 abuts the inner side of the extrusion belt 513. The elastic member 524 is specifically a spring. The elastic member 524 is sleeved on the guide rod 522 and abuts the extrusion pressing block 523 and the support base 521 respectively.

[0072] refer to Figure 1 and Figure 4 An extrusion channel is formed between the extrusion belt 513 and the belt of the conveyor 2. The extrusion belt 513 and the belt of the conveyor 2 move in the same direction and at the same speed, allowing the soft bag to pass through the extrusion channel. As the soft bag passes through the extrusion channel, the elastic force of the elastic member 524 exerts an extrusion force on the soft bag, which can accelerate the leakage of damaged soft bags.

[0073] refer to Figure 1, the second detection work station 6 is same as the mechanism of the first detection work station 4, the second detection work station 6 can detect the pressure value that the soft bag receives. The height adjusting assembly 3 makes the distance between the first detection work station 4 and the second detection work station 6 and the transport mechanism 2 equal, that is, makes the extrusion force of the first detection work station 4 and the second detection work station 6 on the soft bag same, which is beneficial to compare the change of the pressure value before and after extrusion, so as to judge whether the soft bag leaks.

[0074] Reference Figure 1 , the soft bag leak detection and rejection device further comprises a rejection assembly 7, the rejection assembly 7 comprises a rejection driving source 71, a push plate 72 and a material falling bin 73. The rejection driving source 71 specifically adopts a pneumatic cylinder, the rejection driving source 71 is fixedly connected with the transport mechanism 2, the push plate 72 is fixedly connected with the moving end of the rejection driving source 71, and the material falling bin 73 is fixedly connected with the transport mechanism 2. When it is detected that the soft bag transported by the transport mechanism 2 leaks, the soft bag is a defective product, the rejection driving source 71 drives the push plate 72 to move, so that the push plate 72 pushes the defective product on the transport mechanism 2 into the material falling bin 73, and the rejection of the defective product is realized.

[0075] The implementation principle of the soft bag leak detection and rejection device in the embodiment 1 is as follows: the abutting conveying belt 41 and the transport mechanism 2 make the soft bag pass through the material conveying channel, the soft bag is extruded by the force measuring belt wheel 422, and the pressure sensor 423 detects the pressure value that the soft bag receives. Then the extrusion conveying belt 51 and the transport mechanism 2 make the soft bag 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 detection work station 6 detects the pressure value that the soft bag receives again, compares the pressure values of the soft bag before and after extrusion, and judges whether the current soft bag leaks. Finally, the rejection driving source 71 pushes the soft bag that leaks into the material falling bin 73 through the push plate 72, and the rejection of the defective product is realized.

[0076] Embodiment 2:

[0077] The soft bag leak detection and rejection device is provided in the embodiment 2 of the application, and the difference between the embodiment 2 and the embodiment 1 is as follows:

[0078] Reference Figure 6 and Figure 7 In the embodiment, three extrusion work stations 5 are arranged, and the three extrusion work stations 5 are respectively located at the top side and the left and right sides of the transport mechanism 2, that is, the extrusion work station 5 at the top side and the transport mechanism 2 can extrude the top side and the bottom side of the soft bag, and the extrusion work stations 5 at the left and right sides can extrude the left and right sides of the soft bag, so that sufficient extrusion force is provided. For the extrusion work stations 5 at the left and right sides, the moving directions of the extrusion belt bodies 513 are opposite, so that the soft bag rotates on the horizontal plane.

[0079] In this application, if the damaged area of ​​the soft bag is located within the contact area between the extrusion belt 513 and the soft bag, the extrusion belt 513 will block the damaged area to a certain extent, which can easily lead to a slow leakage rate of the soft bag and difficulty in producing a significant volume change, which is not conducive to subsequent detection and comparison. The extrusion stations 5 located on both sides of the conveyor 2 allow the product to rotate on the conveyor 2, which can make the extrusion belt 513 contact different areas of the soft bag, which is conducive to preventing the damaged soft bag from leaking.

[0080] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
