DETAILED DESCRIPTION

[0022] The utility model is further described in detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides a side pattern printing device for the production of paper-plastic packaging boxes, including a support frame 1 and a conveyor belt 2 arranged on the inner side of the support frame 1, a mounting frame 3 is fixedly installed on the top of the support frame 1, a fixing component 4 is fixedly installed inside the mounting frame 3, a printing plate 5 is fixedly installed on the bottom of the fixing component 4, a correction component 6 and a drying component 7 are fixedly installed on the top of the support frame 1, the correction component 6 is arranged on the front side of the mounting frame 3, and the drying component 7 is arranged on the rear side of the correction component 6.

[0024] The packaging box cardboard is conveyed by the conveyor belt 2, and the fixing component 4 arranged in the mounting frame 3 on the support frame 1 cooperates with the correction component 6 on the front side of the fixing component 4, and the position of the packaging box cardboard on the conveyor belt 2 is corrected by the correction component 6 to keep it in the middle, and the printing plate 5 is driven down by the fixing component 4 to press the packaging box cardboard during printing, so as to fix it to avoid deviation during printing and blurred printing, and at the same time, through the drying component 7 arranged on the rear side of the mounting frame 3, the printed packaging box cardboard enters the drying component 7, and the external air is inhaled by the drying component 7, and then heated and blown out from the side without direct contact with the packaging box cardboard, and the drying of the ink on the packaging box cardboard is accelerated by the heat in the drying component 7, so as to accelerate the drying while avoiding direct blowing of hot air to the ink, and achieve a packaging drying effect.

[0025] like Figures 2 to 4 As shown, the correction component 6 includes a fixed frame 61, a bidirectional screw 62 is rotatably installed on the upper inner side of the fixed frame 61, a driving motor 63 connected to the bidirectional screw 62 is fixedly installed on the outer side of the fixed frame 61, a slider 64 is movably hinged on the outer side of the bidirectional screw 62, a clamping plate 65 is fixedly connected to the bottom of the slider 64, a pressure sensor 66 is fixedly installed on the inner side of the clamping plate 65, and an infrared sensor 67 is fixedly installed on the inner side of the fixed frame 61.

[0026] The fixing assembly 4 includes a telescopic rod 41, a mounting frame 2 42 located on the inner side of the mounting frame 1 3 is fixedly installed at the bottom of the telescopic rod 41, a printing plate 5 is fixedly installed at the bottom of the mounting frame 2 42, connecting side panels 43 are fixedly installed on the left and right sides of the mounting frame 2 42, a sleeve 44 is fixedly installed on the top of the connecting side panel 43, a spring 45 is movably connected inside the sleeve 44, an anti-skid plate 46 is fixedly connected to the bottom of the sleeve 44, and a visual sensor 47 is fixedly installed at the front of the inner side of the mounting frame 3.

[0027] When the packaging box reaches the bottom of the infrared sensor 67 and is detected, the driving motor 63 on the outside of the fixed frame 61 is automatically controlled by the controller to drive the bidirectional screw 62 to rotate. The rotation of the bidirectional screw 62 drives the sliders 64 on both sides of the outside to drive the clamping plate 65 to slide inward, and the ball bearings 68 at the bottom of the clamping plate 65 roll along the surface of the conveyor belt 2 to move the clamping plate 65 inward. The clamping plate 65 moves inward to make the pressure sensor 66 contact the side of the package and push the clamping plate 65 inward to keep the packaging box body in the middle position of the conveyor belt 2. The threshold value of the packaging box is preset by the pressure sensor 66. When the clamping force is too large, the driving motor 63 drives the bidirectional screw 62 to reverse and reset the slider 64. The infrared sensor 67 captures the position image of the packaging box and stops the conveyor belt 2 after reaching the predetermined position. The telescopic rod 41 drives the mounting frame 42 to descend. The anti-skid plate 46 located under the mounting frame 42 contacts the other folded surfaces of the packaging box. When the mounting frame 42 drives the printing plate 5 to move downward, the anti-skid plate 46 compresses the spring 45 in the sleeve 44 to fix the packaging box, thereby ensuring that the position of the packaging box is corrected and fixed, avoiding the deviation of the packaging box and ensuring the printing quality.

[0028] like Figure 5 As shown, the drying component 7 includes a drying bin 71, a mounting box 72 is fixedly installed on the top of the inner side of the drying bin 71, a heating pipe 73 is fixedly installed inside the mounting box 72, exhaust ports 74 are provided on the left and right sides of the mounting box 72, a suction fan 75 and a temperature control switch 76 are fixedly installed on the top of the drying bin 71, the suction fan 75 is connected to the mounting box 72, and the temperature control switch 76 is electrically connected to the heating pipe 73.

[0029] The packaging box is sent into the drying chamber 71, and air is sucked into the installation box 72 by the suction fan 75. The air is heated by the heating tube 73 whose temperature is controlled by the thermostat 76, and then discharged into the drying chamber 71 from the exhaust port 74 on the side of the installation box 72. The heat in the drying chamber 71 dries the ink on the packaging box, thereby avoiding direct blowing of hot air on the ink and ensuring the drying effect.

[0030] like Figure 2 As shown, the infrared sensor 67 is arranged at the front side of the bidirectional screw 62, and the slider 64 is arranged outside the bidirectional screw 62 in a left-right symmetrical manner.

[0031] Infrared rays are emitted by the infrared sensor 67 located on the front side of the bidirectional screw 62 to the conveyor belt 2 where they are absorbed. When the infrared rays touch the packaging box, they bounce back and receive signals which are transmitted to the controller for sensitive control. The symmetrically arranged sliders 64 clamp the packaging box cardboard from the side to limit its position to the middle of the conveyor belt 2.

[0032] like Figure 3 and Figure 4As shown, the visual sensor 47 is arranged at the front side of the second mounting frame 42, and the sleeve 44 is symmetrically arranged at the front and rear sides of the top of the connecting side plate 43.

[0033] The visual sensor 47 located in front of the second mounting frame 42 captures the image of the packaging box on the conveyor belt 2 and prints it after the controller determines that it has reached the specified position. The sleeve 44 moves downward with the telescopic rod 41 to press and fix the packaging box shell.

[0034] like Figure 2 As shown, a ball 68 that fits the surface of the conveyor belt 2 is movably engaged at the bottom of the clamping plate 65 .

[0035] The balls 68 adhere to the surface of the conveyor belt 2 and roll as the clamping plate 65 moves to provide support.

[0036] like Figure 5 As shown, a baffle 77 is movably hinged on the rear side of the drying chamber 71 .

[0037] The baffle 77 is provided to shield the drying chamber 71 during drying to reduce heat dissipation.

[0038] The working principle of the side pattern printing device for producing paper-plastic packaging boxes is described in detail below.

[0039] like Figures 1 to 5As shown, the packaging box to be printed is placed on the conveyor belt 2 according to the printing direction and conveyed in the direction of the mounting frame 3. When the packaging box reaches below the infrared sensor 67 and is detected, the conveyor belt 2 is automatically controlled to stop by the controller, and then the driving motor 63 on the outside of the fixing frame 61 is controlled to drive the bidirectional screw 62 to rotate. The rotation of the bidirectional screw 62 drives the sliders 64 on both sides of the outside to drive the clamping plate 65 to slide inward, and the ball bearings 68 at the bottom of the clamping plate 65 roll along the surface of the conveyor belt 2 to move the clamping plate 65 inward. The clamping plate 65 moves inward and the pressure sensor 66 contacts the side of the package and moves inward with the clamping plate 65 to keep the packaging box in the middle position of the conveyor belt 2. The pressure sensor 66 presets a threshold value suitable for the packaging box. When the clamping force is too large, the driving motor 63 drives the bidirectional screw 62 to reverse and reset the slider 64. The packaging box body is then transported to the mounting frame 3 through the conveyor belt 2 again. The infrared sensor 67 captures the packaging box position image. After reaching the predetermined position, the conveyor belt 2 is stopped, and the mounting frame 42 is driven to descend through the telescopic rod 41. The anti-skid plate 46 located under the mounting frame 42 contacts the other folded surfaces of the packaging box. When the printing plate 5 is driven downward by the mounting frame 42, the spring 45 in the sleeve 44 is compressed by the anti-skid plate 46 to fix the packaging box, and the packaging box is printed by the printing plate 5. After that, the conveyor belt 2 is started to send the packaging box into the drying bin 71, and the air is sucked into the mounting box 72 by the suction fan 75. The air is heated by the heating tube 73 whose temperature is controlled by the thermostat 76, and then discharged into the drying bin 71 from the exhaust port 74 on the side of the mounting box 72. The ink on the packaging box is dried by the heat in the drying bin 71, and then transported out of the drying bin 71 in the direction of the baffle 77.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
