A packaging machine equipped with a barcode scanning device

Abstract

This utility model relates to a packaging machine equipped with a barcode scanning device, aiming to solve the technical problem that irregular wrinkles on the surface of current packaging bags prevent the scanning device's recognition lens from clearly capturing the complete barcode image, resulting in a reduced scanning success rate. This affects the continuous operation efficiency of the production line and increases the error risk of quality traceability. The device includes: a belt conveyor with a packaging machine mounted on one side of its top for transporting packaged items; and a barcode scanning mechanism located on the top of the belt conveyor away from the packaging machine for barcode scanning and traceability. This utility model uses circumferentially evenly distributed air jets to create an airflow field, blowing from the bottom of the sleeve onto the surface of the packaging bag. This generates a dispersed smoothing force on the irregular wrinkles, ensuring that the airflow on the bag diffuses from the center to the edge, stretching and flattening randomly distributed wrinkles, such as corner wrinkles of film bags and local bulges of aluminum foil bags, keeping the QR code area flat and thus improving the success rate of QR code scanning on the bag.

Description

Technical Field

[0001] This utility model relates to the technical field of barcode scanning devices for packaging machines, specifically a packaging machine equipped with a barcode scanning device. Background Technology

[0002] In packaging production lines in industries such as food and daily chemicals, packaging machines often integrate barcode scanning devices to achieve automated traceability of product information. These devices scan the QR codes or barcodes on the surface of the packaging bags to associate key data such as production batches and shelf life.

[0003] Existing packaging machines often experience irregular wrinkles on their conveyor mechanisms when transporting bags, especially soft materials like film bags and aluminum foil bags. This is due to fluctuations in conveying speed, uneven tension control, or deviations in material distribution within the bag. These wrinkles can deform the barcode area, stretch the pattern, or partially obscure it, preventing the barcode scanner's lens from clearly capturing the complete barcode image. This reduces the scanning success rate, impacting the continuous operation efficiency of the production line and increasing the risk of errors in quality traceability. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a packaging machine equipped with a barcode scanning device to solve the technical problem that irregular wrinkles on the surface of the current packaging bag make it impossible for the scanning device's recognition lens to clearly capture the complete barcode image, resulting in a reduced scanning success rate, which not only affects the continuous operation efficiency of the production line, but also increases the error risk of quality traceability.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A packaging machine equipped with a barcode scanning device is designed, comprising:

[0006] A belt conveyor with a packaging machine on one side of its top for transporting packaged items;

[0007] A barcode scanning mechanism, located at the top of the belt conveyor on the side away from the packaging machine, is used for barcode scanning and traceability. The barcode scanning mechanism includes:

[0008] A sleeve, open at the bottom and hollow inside, is mounted on a belt conveyor at both ends by mounting components;

[0009] The scanning head, fixed inside the sleeve, is used to scan the QR code on packaged items;

[0010] Multiple air jets are equidistantly distributed along the circumference of the inner wall of the sleeve, all of which are connected to the hollow interlayer of the sleeve and are set corresponding to the scanning head;

[0011] The jet assembly, located at the top of the sleeve, supplies air to the hollow interlayer, allowing the airflow to be ejected through the jet holes to clean dust from the scanning head and flatten the outer packaging of the items.

[0012] Preferably, the jet assembly includes:

[0013] The blower is fixedly connected to one side of the top of the sleeve;

[0014] The air inlet pipe has one end fixedly connected to the air outlet of the blower and the other end fixedly connected to the top of the sleeve, and is connected to the hollow interlayer of the sleeve.

[0015] Preferably, a filter screen is installed at the air inlet of the blower.

[0016] Preferably, the mounting assembly includes two connecting columns, both of which are mounted on both sides of the surface of the belt conveyor. A telescopic component is provided between the two connecting columns and the sleeve. A connecting plate is fixedly connected to the bottom of each of the two connecting columns. A fixing bolt passes through each of the two connecting plates, and the two fixing bolts are threadedly connected to the surface of the belt conveyor.

[0017] Preferably, the telescopic assembly includes two connecting cylinders and two screws. The two connecting cylinders are symmetrically fixedly connected to the sleeve, and the two screws are slidably connected to the two connecting cylinders respectively. Nuts are threaded onto the outer side of each of the two screws.

[0018] Preferably, a plurality of supplementary lighting beads are installed at the bottom opening of the sleeve, and the plurality of supplementary lighting beads are distributed in a circular pattern at equal intervals at the bottom of the sleeve.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. Airflow smoothing wrinkles: An airflow field is formed by circumferentially evenly distributed jet holes, blowing from the bottom of the sleeve onto the surface of the packaging bag. This generates a dispersed smoothing force on irregular wrinkles, ensuring that the airflow on the bag diffuses from the center to the edge, stretching and flattening randomly distributed wrinkles, such as corner wrinkles of film bags and local bulges of aluminum foil bags, keeping the QR code area flat, thereby improving the success rate of QR code scanning on the bag.

[0021] 2. Simultaneous cleaning: The airflow from the jet nozzles blows away dust particles from the surface of the scanner head while flattening the packaging bag, preventing dust accumulation from affecting scanning clarity, avoiding error problems caused by dust accumulation in open scanner heads, and reducing the frequency of manual cleaning.

[0022] 3. Airflow adjustment: The airflow intensity can be automatically adjusted according to the packaging bag material and conveying speed to ensure that wrinkles can be effectively smoothed and the scanning head can be kept clean under different working conditions, adapting to the diverse packaging needs of the production line and improving the equipment's versatility.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0028] Example 1: A packaging machine equipped with a barcode scanning device, see [link to example]. Figures 1 to 3 The system includes: a belt conveyor 1 with a packaging machine 11 on one side of its top for conveying packaged items; a barcode scanning mechanism located on the top of the belt conveyor 1 away from the packaging machine 11 for barcode scanning and traceability, the barcode scanning mechanism including: a sleeve 4 with an open bottom and a hollow interior, both ends of which are mounted on the belt conveyor 1 via mounting components; a scanning head 6 fixed to the inner cavity of the sleeve 4 for scanning the QR code of the packaged items; multiple air jets 41 equidistantly distributed along the circumference of the inner wall of the sleeve 4, all communicating with the hollow interlayer of the sleeve 4 and corresponding to the scanning head 6; and an air jet assembly located at the top of the sleeve 4 for supplying air to the hollow interlayer, so that the airflow is ejected through the air jets 41 to clean the dust from the scanning head 6 and flatten the outer packaging of the items.

[0029] This device, through its belt conveyor 1, barcode scanning mechanism, and air jet assembly, achieves the following during use:

[0030] Airflow smooths wrinkles: An airflow field is formed by circumferentially equidistant jet holes 41, which blows from the bottom of the sleeve 4 onto the surface of the packaging bag, generating a dispersed smoothing force on irregular wrinkles. This ensures that the airflow on the bag diffuses from the center to the edge, stretching and flattening randomly distributed wrinkles, such as the corner wrinkles of film bags and the local bulges of aluminum foil bags, keeping the QR code area flat and thus improving the success rate of QR code scanning on the bag.

[0031] Simultaneous cleaning: The airflow through the jet nozzle 41 blows away dust particles from the surface of the scanner head 6 while flattening the packaging bag, preventing dust accumulation from affecting scanning clarity, avoiding the error problem caused by dust accumulation in the open scanner head 6, and reducing the frequency of manual cleaning.

[0032] Airflow regulation: The airflow intensity can be automatically adjusted according to the packaging bag material and conveying speed to ensure that wrinkles can be effectively smoothed and the scanning head 6 can be kept clean under different working conditions, adapting to the diverse packaging needs of the production line and improving the equipment's versatility.

[0033] For details, see Figure 1 The jet assembly includes: a blower 5, fixedly connected to the top side of the sleeve 4; and an air inlet pipe 52, one end of which is fixedly connected to the air outlet of the blower 5, and the other end is fixedly connected to the top of the sleeve 4 and communicates with the hollow interlayer of the sleeve 4. By starting the blower 5 and cooperating with the air inlet pipe 52, air is directly supplied to the hollow interlayer of the sleeve 4 to form a stable positive pressure environment, ensuring that the airflow intensity of each jet hole 41 is consistent, avoiding local wrinkles not being smoothed due to uneven airflow or excessive blowing causing the packaging bag to shift, and improving the scanning success rate.

[0034] Further, see Figure 1 A filter screen 51 is installed at the air inlet of the blower 5. The filter screen 51 can intercept large particulate impurities in the air, preventing them from entering the blower 5 with the airflow and causing impeller wear or blockage of the jet hole 41. The clean air intake ensures that the ejected airflow is free of impurities that contaminate the surface of the scanning head 6, thus ensuring the scanning effect of the scanning head 6.

[0035] It is worth noting that, see Figure 1 The mounting assembly includes two connecting posts 2, both of which are mounted on both sides of the surface of the belt conveyor 1. A telescopic assembly is provided between each of the connecting posts 2 and the sleeve 4. A connecting plate 21 is fixedly connected to the bottom of each of the two connecting posts 2, and a fixing bolt 22 passes through each of the two connecting plates 21. Both fixing bolts 22 are threaded onto the surface of the belt conveyor 1. The rigid fixing of the connecting plates 21 and the fixing bolts 22 securely locks the scanning mechanism in a preset position on the belt conveyor 1. Combined with the height adjustment of the telescopic assembly, this ensures that the scanning head 6 and the QR code on the packaging bag remain vertically aligned. Furthermore, the stable connection between the connecting posts 2 and the connecting plates 21 absorbs the vibration of the belt conveyor 1, preventing the scanning head 6 from producing ghost images due to vibration and ensuring clear code capture.

[0036] It is worth noting that, see Figure 3 The telescopic assembly includes two connecting cylinders 31 and two screws 3. The two connecting cylinders 31 are symmetrically fixedly connected to the sleeve 4, and the two screws 3 are slidably connected to the two connecting cylinders 31 respectively. Nuts 32 are threaded on the outer side of the two screws 3. By turning the nuts 32, the connection length between the connecting cylinders 31 and the screws 3 can be adjusted, so that the scanning device can be installed on belt conveyors 1 of different widths, thereby improving the practicality of the device.

[0037] It is worth mentioning that, see Figure 2Multiple supplementary light beads 7 are installed at the bottom opening of the sleeve 4, and the multiple supplementary light beads 7 are distributed in a circular pattern at equal intervals at the bottom of the sleeve 4. By the supplementary light beads 7 being distributed in a circular pattern along the bottom of the sleeve 4, uniform light can be projected onto the surface of the packaging bag from multiple angles, avoiding differences in the brightness of the code image caused by uneven light, and ensuring that the scanning head 6 captures a complete and clear code image.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
