[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] like Figures 1-2 As shown, a coding device includes: a conveyor belt 1, a pressure roller device 2, an encoder 3, a coding machine 4, and a detector 5. The pressure roller device 2 tensions the conveyor belt 1; the encoder 3 is signal-connected to the pressure roller device 2 and is located above the conveyor belt 1; the coding machine 4 is located above the conveyor belt 1; and the detector 5 is also located above the conveyor belt 1. The coding machine and the detector 5 are arranged sequentially along the transport direction of the conveyor belt 1.

[0028] It is worth noting that the product is laid flat on the conveyor belt 1. As the conveyor belt 1 transports the product past the inkjet printer 4 and the detector 5, the inkjet printer 4 prints the product and the detector 5 checks the printed product.

[0029] In use, the detector 5 and the inkjet printer 4 are aligned along the conveyor belt 1 to facilitate the inspection of the printed products.

[0030] The encoder 3 is connected to the pressure roller device 2. The encoder 3 is used to detect the flatness of the conveyor belt 1, whether the belt jumps or shakes, and the operating speed of the conveyor belt 1. The pressure roller device 2 tensions the conveyor belt 1. The encoder 3 and the pressure roller device 2 are connected by a signal. The pressure roller device 2 adjusts the tension according to the pressure roller device 2 to achieve dynamic adjustment and ensure the stability of the conveyor belt 1 during transportation.

[0031] Preferably, the conveyor belt 1 serves as the main carrier for product transportation. The conveyor belt 1 operates in a cyclic motion, and its two ends are driven and guided by drive devices and steering wheels. A pressure roller device 2 is installed above the conveyor belt 1 to apply appropriate tension. The pressure roller device 2 includes a tensioning roller 21 and a mounting assembly 22. One end of the mounting assembly 22 is fixedly mounted, and the tensioning roller 21 is mounted on the other end of the mounting assembly 22, resting against the conveyor belt 1.

[0032] Furthermore, such as Figure 3 As shown, the mounting assembly 22 includes a rotating shaft 221 and a mounting arm 222. The rotating shaft 221 is fixedly mounted, and the mounting arm 222 is mounted on the rotating shaft 221. The mounting arm 222 swings about the rotating shaft 221 as an axis, and the tension wheel 21 is mounted on the mounting arm 222. The tension of the conveyor belt 1 is adjusted by the swinging of the mounting arm 222.

[0033] The encoder 3 is installed above the conveyor belt 1, and its detection part maintains a certain contact with the conveyor belt 1 or has a small gap. The encoder 3 is used to detect the flatness of the conveyor belt 1, whether the belt jumps or vibrates, and the operating speed of the conveyor belt 1.

[0034] Preferably, the encoder 3 and the pressure roller device 2 are connected via a signal line to transmit signals. The encoder 3 has a control system, which sends adjustment commands to the pressure roller device 2 via the signal line based on the status information of the conveyor belt 1 detected by the encoder 3.

[0035] Preferably, when the encoder 3 detects a flatness problem in the conveyor belt 1, such as local depressions or bulges, the control system will immediately send an adjustment command to the pressure roller device 2. The pressure roller device 2 adjusts the tension on the conveyor belt 1 according to the command, so that the conveyor belt 1 returns to a flat state.

[0036] Preferably, the encoder 3 can also detect whether the conveyor belt 1 jumps or vibrates during operation. When such a problem is detected, the control system will also send an adjustment command to the pressure roller device 2. The pressure roller device 2 will dynamically adjust the tension according to the command to eliminate the jumping or vibrating and ensure the stable operation of the conveyor belt 1.

[0037] Preferably, the encoder 3 can also detect the operating speed of the conveyor belt 1 in real time and transmit the data to the control system. The control system monitors the speed of the conveyor belt 1 according to a preset speed range. When the speed of the conveyor belt 1 exceeds the preset range, the control system sends an adjustment command to the pressure roller device 2 to change the operating speed of the conveyor belt 1 by adjusting the tension, so as to keep it within the preset range.

[0038] The encoder 3 can be selected according to the requirements. For example, the encoder 3 in the Chinese application publication CN114313821A, which describes a conveyor belt tension adjustment device and an encoder 3 shock absorption device and its usage method, is used as an example only to illustrate that the encoder 3 is a conventional technical means in this field.

[0039] The control system receives the detection signal from the encoder 3 and dynamically adjusts the pressure roller device 2 according to the signal. The control system can employ a PLC programmable logic controller or a microprocessor such as a microcontroller. By programming and setting parameters, the control system can achieve precise control over the stability of the conveyor belt 1.

[0040] In this application, the inkjet printer 4 and detector 5 are sequentially arranged along the conveyor belt 1 in the transport direction, allowing for real-time monitoring of the inkjet printing effect after printing, facilitating adjustments to the production line based on the inkjet printing results. Specifically, the transport direction of the conveyor belt 1 is... Figure 2 In the direction from right to left, the inkjet printer 4 is located to the right of the detector 5.

[0041] The encoder 3 is connected to the pressure roller device 2 via a signal connection, enabling real-time monitoring of the movement status of the conveyor belt 1, including its speed and position. This real-time information feedback provides precise control information for the inkjet printer 4, ensuring that the inkjet printing operation is performed at the correct position and speed, thereby improving the accuracy and consistency of the inkjet printing.

[0042] The tensioning effect of the pressure roller device 2 on the conveyor belt 1 not only ensures the smooth operation of the conveyor belt 1, but also reduces the coding error caused by the slack or vibration of the conveyor belt 1. This design improves the overall stability and reliability of the coding device, enabling it to maintain high performance in various production environments.

[0043] The inkjet printer 4 and detector 5 are arranged sequentially along the conveyor belt 1 in the transport direction, allowing products to continuously pass through the coding area and be inspected after coding is completed. This compact layout design reduces product waiting time and improves production efficiency.

[0044] The coding device of this application can adapt to products of different sizes, shapes and weights. The adjustability of the pressure roller device 2 and the conveyor belt 1 ensures that the product can pass through the coding area in a stable state, while the flexibility of the encoder 3 and the coding machine 4 allows for adjustments according to different coding requirements.

[0045] Preferably, the coding device of this application is an important component of an automated production line. By cooperating with upstream automatic feeders and downstream automatic receiving machines, it can achieve fully automated processing of products from input to output, greatly reducing manual intervention and production costs.

[0046] Furthermore, the coding device also includes a sensor 6, which is located in front of the coding machine 4 on the conveyor belt 1 along the conveying direction.

[0047] Sensor 6 can detect the status of a product about to enter the coding area in advance, such as its position, size, and shape. This early warning mechanism allows the coding device to be fully prepared before the product arrives at the coding machine 4, avoiding coding errors or equipment malfunctions caused by abnormal product status.

[0048] By using sensor 6 to monitor the product in real time, the coding device can more precisely control the start-up timing and coding position of the coding machine 4. This precise control reduces waiting time and resource waste during the coding process, further improving coding efficiency.

[0049] Sensor 6 can detect subtle differences in the product, such as dimensional deviations and shape variations. This information can be fed back to the control system, enabling inkjet printer 4 to perform personalized inkjet printing operations based on the actual condition of the product, thereby enhancing product quality control.

[0050] The coordinated operation of sensor 6 and inkjet printer 4 enables the inkjet device to react quickly to abnormal situations, such as pausing inkjet printing or adjusting inkjet parameters. This intelligent response mechanism improves the reliability and stability of the equipment and reduces production interruptions caused by equipment failure.

[0051] The addition of sensor 6 further enhances the automation level of the inkjet printing device. Sensor 6 can automatically detect and process product information, completing the inkjet printing operation without manual intervention. This highly automated production method improves production efficiency and reduces labor costs.

[0052] like Figures 4-5 As shown, the coding device also includes a first mounting bracket 7, on which the sensor 6 and the coding machine 4 are both mounted. The first mounting bracket 7 includes a first mounting part 71 and a second mounting part 72. The first mounting part 71 is fixedly disposed, and the sensor 6 is mounted on the first mounting part 71. The second mounting part 72 is slidably connected to the first mounting part 71 in a direction close to or away from the conveyor belt 1, and the coding machine 4 is mounted on the second mounting part 72.

[0053] Specifically, see Figure 5The first mounting part 71 is provided with a slide rail 711, and the second mounting part 72 is provided with a slide rail 712 that cooperates with the slide rail 711. The first mounting part 71 and the second mounting part 72 are slidably connected through the cooperation of the slide rail 711 and the slide rail 712.

[0054] Furthermore, the first mounting bracket 7 also includes an adjustment knob 73 for adjusting the position of the second mounting part 72 relative to the first mounting part 71. The adjustment knob 73 is arranged in a direction perpendicular to the conveyor belt 1. The second mounting part 72 and the adjustment knob 73 are fixedly connected, and the adjustment knob 73 and the first mounting part 71 are threadedly connected.

[0055] The second mounting part 72 is slidably connected to the first mounting part 71 along the direction close to or away from the conveyor belt 1, allowing the inkjet printer 4 to be positioned according to products of different sizes or types. This flexibility ensures that the inkjet printer 4 can accurately align with the product, achieving high-quality coding regardless of changes in product size or position.

[0056] Through the cooperation of slide rail 711 and slide path 712, the second mounting part 72 can slide smoothly and precisely, thereby realizing fine adjustment of the position of inkjet printer 4. This precise adjustment capability is crucial to ensuring the accuracy of the inkjet printing position, especially when dealing with products with high precision requirements.

[0057] The design of the first mounting bracket 7 makes the installation of the sensor 6 and the inkjet printer 4 simpler and more intuitive. At the same time, because the second mounting part 72 can slide, maintenance personnel can more easily access the inkjet printer 4 to perform necessary maintenance or repair work, reducing maintenance difficulty and cost.

[0058] The quick adjustment of the inkjet printer's 4-position capability means that the production line can adapt to different types or sizes of products more quickly, reducing the time required for product changeovers or equipment adjustments. This helps improve the overall efficiency and flexibility of the production line.

[0059] The compact design of the first mounting bracket 7 reduces the space occupied by the entire coding unit, helping to optimize the spatial layout of the production site. Furthermore, since it is not necessary to configure a separate coding machine 4 for each product of different sizes, equipment costs can be saved.

[0060] The adjustment knob 73 allows the operator to easily adjust the position of the second mounting section 72 without the need for complex tools or equipment. This convenience improves operational efficiency and reduces the risk of equipment damage due to improper operation.

[0061] The threaded connection between the adjustment knob 73 and the first mounting part 71 ensures the stability of the second mounting part 72 after adjustment. This design prevents the inkjet printer 4 from shifting due to vibration or impact during the inkjet printing process, thereby ensuring the stability of the inkjet printing quality.

[0062] like Figure 6 As shown, the coding device also includes a second mounting bracket 8, which includes a third mounting part 81 and a fourth mounting part 82. The third mounting part 81 is fixedly disposed, and the fourth mounting part 82 is slidably mounted on the third mounting part 81. The detector 5 is mounted on the fourth mounting part 82. The second mounting bracket 8 also includes a locking nut 83. The third mounting part 81 is provided with a sliding groove 811, and the fourth mounting part 82 slides in the sliding groove 811. The locking nut 83 passes through the fourth mounting part and is operably locked in the sliding groove 811.

[0063] The fourth mounting section 82 slides within the groove 811 of the third mounting section 81, allowing the detector 5 to adjust its position as needed. This design enhances overall flexibility, enabling it to adapt to the inspection requirements of products of different sizes, shapes, or positions.

[0064] The rapid adjustment of detector 5's position means the production line can adapt to different types or sizes of products more quickly, reducing the time required for product changeovers or equipment adjustments. This helps improve the overall efficiency and flexibility of the production line.

[0065] The design of the locking nut 83 ensures the stability of the fourth mounting part 82 after adjustment. The locking nut 83 prevents the detector 5 from shifting due to vibration or impact during detection, thus guaranteeing the stability and accuracy of the detection results.

[0066] The locking nut 83 is simple and convenient to operate, allowing the operator to easily adjust and secure the position of the detector 5. This convenience improves operational efficiency and reduces the risk of equipment damage due to improper operation.

[0067] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
