Description

Technical Field

[0001] This utility model relates to the field of flexible packaging product processing technology, and in particular to a self-standing bag product packaging inspection system. Background Technology

[0002] With economic development and technological progress, people's market demands for various commodities are increasingly showing a trend towards high quality, convenience, and diversification, which is particularly prominent in industries such as food, pharmaceuticals, and chemicals. Stand-up pouches, with their good airtightness and ease of carrying, have emerged to meet this demand (a stand-up pouch is a type of flexible packaging bag with a screw-on top, allowing the product to stand upright after being filled). The filling equipment industry, which is associated with it, is experiencing rapid development, especially with the introduction of automation and intelligent control technologies, which have improved filling speed and efficiency.

[0003] However, while a large number of stand-up pouches are being produced, the inspection of their packaging quality has become a bottleneck for the shipment of qualified products. In particular, problems such as leakage and improper sealing of product packaging are difficult to detect. Relying solely on manual inspection is inefficient and has a high error rate, which in turn affects the company's economic benefits, brand reputation, and customer trust.

[0004] Based on this, the present invention provides a self-standing bag product packaging inspection system to solve one or more of the problems mentioned above. Utility Model Content

[0012] Preferably, a gap is left between the second and third side belts for the product to pass through. A horizontally adjustable bracket is installed on the outer wall of the leak detection bracket. The output end of the linear motor is fixedly connected to the horizontally adjustable bracket. The linear motor can drive the leak detection bracket to move, thereby changing the gap between the second and third side belts.

[0013] Preferably, a baffle is fixedly installed on the first support frame, a baffle is fixedly installed on the second support frame, a rotating shaft is installed on the side of the first support frame away from the baffle through a fixed bracket, a mounting bracket is fixedly connected to the end of the first support frame away from the pressure testing box, a rotating shaft is installed on the top of the mounting bracket, and a rotating shaft is symmetrically installed on both ends of the second support frame.

The linear motor drives the first leak detection bracket to move, allowing flexible adjustment of the spacing between the second and third side-mounted belts to accommodate products of different sizes and improve equipment versatility. The product conveying path is rationally designed; the "S"-shaped turn from the flat belt to the first side-mounted belt smoothly converts horizontal products to vertical positions. Combined with the geared motor and drive motor driving the relevant transmission components, this achieves fully automated conveying, reducing manual intervention and improving efficiency. The pressure detection chamber adopts a symmetrical support structure with a precise layout of rollers and belt components. The stable installation of each component ensures long-term stable operation and reduces maintenance costs. The modular component design also facilitates daily inspection and replacement of vulnerable parts, making operation convenient. This effectively solves the problems of low leakage detection efficiency, poor adaptability, and high labor costs associated with stand-up pouch packaging, demonstrating significant practical value.

[0032] Preferably, a filling machine turntable 35 is installed on the surface of the testing table 38, and a support frame 2 8, a support frame 1 5 and a pressure testing box 1 are arranged sequentially on the side of the testing table 38 along the product conveying direction.

[0033] Preferably, the detection signal from the pressure sensor is transmitted via a wire (or wireless module) to a conventional signal identification system (such as a PLC controller). This signal identification system has a built-in comparison algorithm that can automatically calculate the pressure difference between the inlet and outlet and determine whether the product is leaking.

[0034] Preferably, the signal recognition system transmits the judgment result to the rejection device (pneumatic push rod) installed at the outlet of the pressure testing box, and the rejection device rejects the unqualified products.

[0035] The working principle and beneficial effects of the above scheme are as follows: During use, the filled and capped products are pushed down from the filling machine turntable 35 in sequence by the cylinder and conveyed to the flat belt 7. The products are then conveyed by the flat belt 7 to the side upright belt 6 and the chain conveyor belt 4. Through this conveying, the products are vertically lifted and conveyed to the pressure detection box 1 between the side upright belt 34 and the side upright belt 16, which forms a compression on the abdomen of the stand-up pouch products. The two sets of pressure sensors 13 installed at the inlet and outlet of the pressure detection box 1 measure the pressure value of the stand-up pouch products passing through the inlet and outlet. The signal recognition system compares and subtracts the pressure values ​​before and after the pressure. Products with a certain difference are suspected of leakage. The rejection device rejects the unqualified products according to the system instructions. Products with no difference or a reasonable difference pass normally.

[0036] The movement of the stand-up pouch within the pressure testing chamber 1 is powered by a geared motor 18, which drives the drive roller 11 to rotate. This, in turn, causes the side belt 16 to reciprocate under the support of nylon roller 12 and nylon roller 15. Friction then drives the stand-up pouch between the side belt 34 and the side belt 16. The bottom-mounted chain conveyor belt 4 also assists in the movement, driving the pulley 26 to rotate via a drive motor 25. The belt 33 drives the pulleys 29 and 30 to rotate synchronously, which in turn drives the side belt 6 and the flat belt 7 to continuously transport products. Due to the "S"-shaped design of the side belt 6, products transported horizontally from the flat belt 7 can be changed to a vertical position via the side belt 6, making it convenient to enter the pressure testing chamber 1 for pressure testing. Furthermore, the linear motor can drive the leak detection bracket 9 to move, thereby changing the distance between the side belt 16 and the side belt 34, thus adapting to stand-up pouches of different sizes.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
