[0001] The utility model relates to the technical field of corrugated paperboard production equipment, in particular to a paper loading device used for corrugated paper printing. Background Art

[0002] Corrugated cardboard has become a widely used packaging material. Due to its lightness, durability and recyclability, corrugated cardboard has been widely used in many industries. In order to meet the diverse needs of the market, the printing of corrugated cardboard has become particularly important, and it needs to provide product-related information so that users can know the contents of the box.

[0003] Corrugated cardboard is often used to make packaging boxes or packaging cases, so it is usually a rectangular structure. In traditional corrugated paper printing production lines, the production line is often optimized and set for only one specification of corrugated cardboard. This means that when different specifications of corrugated cardboard need to be printed, the factory must make cumbersome manual adjustments to the entire production line, which is not only inefficient, but also prone to errors, affecting the printing quality. What's more, when there is a demand for rectangular corrugated cardboard of various sizes in the market, the factory often needs to configure multiple production lines. This not only increases production costs, but also brings huge space and management challenges. Moreover, during the production process, manual sorting is required to put corrugated cardboard of different specifications into the corresponding production line, which undoubtedly increases labor costs and operational complexity.

[0020] See also Figure 1-2 As shown, the utility model relates to a paper loading device for corrugated paper printing.

[0021] Example 1

[0022] A paper feeding device for corrugated paper printing, comprising: a camera 7, a limit device and a control terminal 9, wherein the camera 7 is arranged above the limit device, the control terminal 9 is arranged on one side of the limit device, and the control terminal 9 is communicatively connected with the camera 7 and the limit device;

[0023] The limiting device comprises a printing platform 1 and four limiting blocks 6, wherein the limiting blocks 6 are arranged on the table of the printing platform 1, and the limiting blocks 6 are connected to the printing platform 1 through a movable rod 2, and the limiting blocks 6 are of a right-angle structure, and the four limiting blocks 6 are used to be separably matched with the four corners of the rectangular corrugated cardboard; both ends of the limiting blocks 6 are provided with distance sensors 3, and the distance sensors 3 are connected to the control terminal 9 for communication, and a pressure sensor 4 is arranged in the groove of the limiting block 6, and the pressure sensor 4 is connected to the control terminal 9 for communication;

[0024] A control chip is disposed in the printing platform 1 , the movable rod 2 is electrically connected to the control chip, and the control chip is communicatively connected to the control terminal 9 .

[0025] In this embodiment, when a rectangular corrugated cardboard is fed into the production line, the camera 7 is immediately activated to monitor the size, shape and position of the cardboard in real time. These data are then transmitted to the control terminal 9, which is located on one side of the limit device for easy observation and operation by the operator. The movable rod 2 can be adjusted up and down and can also be translated to accommodate corrugated cardboards of different sizes and shapes. When a rectangular corrugated cardboard is fed into the printing platform 1, the control chip receives the command of the control terminal 9 to control the movable rod 2, and fine-tunes it according to the size and shape of the cardboard to ensure that the four limit blocks 6 are perfectly aligned with the four corners of the cardboard. This combination of telescoping and translation allows the movable rod 2 to quickly and accurately position each limit block 6, regardless of the size of the cardboard. This design not only keeps the cardboard stable during the printing process, but also ensures the accuracy and quality of the printing.

[0026] When the four limit blocks 6 have completed the positioning of the rectangular corrugated cardboard, the distance sensor 3 collects the distance between the adjacent limit blocks 6 and compares and corrects the distance data through the data of other distance sensors 3, and then sends it to the control terminal 9 to determine the length and width of the rectangular corrugated cardboard, so that rectangular corrugated cardboards of different sizes can be printed according to the preset printing task later. The function of the pressure sensor 4 is to monitor the contact pressure between the cardboard and the limit blocks 6 in real time. When the cardboard is fixed, if the pressure is too high or too low, it may cause the cardboard to shift or the printing quality to decline. Therefore, through these pressure sensors 4, the control terminal 9 can ensure that the pressure between the cardboard and the limit blocks 6 is always maintained within an ideal, preset range, thereby ensuring that the cardboard remains stable throughout the printing process and obtains the best printing effect. Finally, the rectangular corrugated cardboard is accurately moved to the printing area through the limit blocks 6 and the movable rod 2 to achieve accurate printing.

[0027] Example 2

[0028] According to the paper loading device for corrugated paper printing described in Example 1, a buffer colloid is also arranged in the groove of the limit block 6; an alarm light 8 is arranged on one side of the control terminal 9, and the alarm light 8 is electrically connected to the control terminal 9; a display screen 10 is arranged on the other side of the control terminal 9, and the display screen 10 is electrically connected to the control terminal 9; a speaker is arranged on one side of the display screen 10, and the speaker is electrically connected to the control terminal 9.

[0029] In this embodiment, the setting of the buffer colloid can effectively absorb and disperse the impact force that may be generated during the placement or movement of the corrugated cardboard, thereby ensuring the integrity of the cardboard and the long service life of the printing platform 1. The alarm light 8 can emit warning signals of different colors and frequencies according to the production status, machine failure or other critical situations, helping the operator to understand the production situation in time and respond quickly. The display screen 10 allows the operator to view production data, machine status and other key information in real time, and can also intuitively perform equipment settings and parameter adjustments. In order to improve the convenience of operation, a speaker is also added to one side of the display screen 10. This speaker is electrically connected to the control terminal 9 and can provide the operator with real-time audio feedback, such as machine startup sound, warning sound or other key operation prompts, to ensure the smoothness and safety of the production process.

[0030] Example 3

[0031] According to the paper loading device for corrugated paper printing described in Example 2, the table top of the printing platform 1 is also provided with a light-emitting device; the table top of the printing platform 1 is also provided with a temperature sensor 5, and the temperature sensor 5 is communicatively connected with the control terminal 9; the material of the movable rod 2 is stainless steel.

[0032] In this embodiment, the light emitting device provides uniform and bright backlight, so that the camera 7 can more accurately identify the light-shielded part, that is, the position of the corrugated cardboard, from the video image. Under this setting, when the corrugated cardboard is placed on the printing platform 1, the camera 7 and the control terminal 9 can easily distinguish the position of the corrugated cardboard on the printing platform 1, thereby improving the accuracy of positioning the corrugated cardboard. The temperature sensor 5 monitors the temperature in real time to prevent and warn of possible fire situations. There is a risk of overheating or fire caused by mechanical friction, electrical failure or other reasons during the production process. Therefore, the temperature sensor 5 is set on the printing platform 1 to monitor the temperature of the platform in real time. Once the temperature exceeds the preset safety range, the sensor will immediately transmit this information to the control terminal 9. The movable rod 2 made of stainless steel also adds a layer of protection to the safety of the entire device. The characteristics of stainless steel make it stable even in a high temperature environment and not easy to deform or damage, thereby ensuring that the corrugated cardboard can be accurately and stably positioned under any circumstances. The safety and reliability of the equipment under long-term and high-intensity work are improved.
