Description

Technical Field

[0001] This utility model relates to the field of white cardboard processing technology, and in particular to a white cardboard drying device. Background Technology

[0002] White cardboard, due to its relatively uniform fiber structure, surface layer containing fillers and sizing agents, and a coating, undergoes multi-roll calendering, resulting in a denser texture, more uniform thickness, and generally a whiter, smoother surface. It exhibits more even ink absorption, less surface dusting and linting, and is stronger and more durable. Widely used in painting, writing, and printing, white cardboard's smooth surface makes it suitable for various drawing media. The drying process is particularly crucial in white cardboard production, directly impacting its final quality.

[0003] In existing white cardboard drying processes, the white cardboard is usually placed on a conveyor belt and heated from above. However, this can lead to incomplete drying of the bottom of the white cardboard, affecting its quality. Utility Model Content

[0004] The purpose of this invention is to provide a white cardboard drying device that can heat and dry both sides of white cardboard, thereby improving the quality of white cardboard.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a white cardboard drying device, including a frame, an inlet and an outlet on the frame, a first drying plate fixedly arranged inside the frame, a feeding component at one end of the first drying plate located at the inlet, a second drying plate located at the end of the first drying plate away from the feeding component, a flipping component inside the frame for grabbing white cardboard on the first drying plate and flipping it 180° to place it on top of the second drying plate; a heating component is arranged above both the first and second drying plates, and a discharging component is arranged at the end of the second drying plate away from the first drying plate located at the outlet.

[0006] By adopting the above technical solution, the white cardboard that needs to be dried is fed into the feeding assembly through the inlet. The feeding assembly sends the white cardboard to the first drying plate. The heating assembly at the top of the first drying plate dries the upper surface of the white cardboard. Then, the flipping assembly grabs the white cardboard from the first drying plate, flips it 180°, and places it on top of the second drying plate with the lower surface of the white cardboard facing up. Then, the heating assembly above the second drying plate dries the lower surface of the white cardboard, thereby achieving the effect of drying both sides of the white cardboard separately, ensuring complete drying, improving the quality of the white cardboard, and then the unloading assembly sends the white cardboard out through the discharge port.

[0007] A further feature of this invention is that the flipping assembly includes a support frame disposed in the frame, a rotating rod rotatably connected to the support frame, pneumatic grippers fixedly connected to both ends of the rotating rod, the pneumatic grippers being used to grip white cardboard, and a drive assembly for driving the rotating rod to rotate being disposed on the support frame.

[0008] By adopting the above technical solution, the pneumatic gripper starts to pick up the white cardboard, and the drive component controls the rotating rod to rotate, thereby controlling the pneumatic gripper to flip 180 degrees and place the white cardboard on the second drying plate.

The transmission rod is rotatably connected to a support frame, and a first cylinder is hinged to the end of the driving rod away from the transmission rod. The end of the first cylinder away from the driving rod is hinged to the support frame.

[0010] By adopting the above technical solution, the first cylinder in the drive assembly is started, controlling the drive rod to rotate, which in turn drives the transmission rod to rotate, thereby controlling the second gear fixedly connected to the transmission rod to rotate, and then controlling the first gear meshing with the second gear to rotate, thereby controlling the pneumatic gripper to flip and place the white cardboard on the second drying plate.

[0011] A further feature of this invention is that the upper surfaces of both the first drying plate and the second drying plate are provided with grooves for the pneumatic grippers to be inserted, and the pneumatic grippers are provided with buffers made of rubber.

[0012] By adopting the above technical solution, a clamping rod of the pneumatic gripper can be placed in the groove. When the pneumatic gripper opens, the white cardboard can smoothly enter the first drying plate, which helps to keep the white cardboard in a horizontal state. The pneumatic gripper is a rigid clamp, and the buffer can prevent damage to the white cardboard during clamping.

[0013] A further feature of this invention is that the drying assembly includes a fixed frame fixedly connected to the top of the frame, and a heating plate is disposed inside the fixed frame.

A control assembly is provided on the frame to control the robotic arms to feed the white cardboard on the second drying plate into the second conveyor belt.

[0016] By adopting the above technical solution, the first conveyor belt feeds the white cardboard onto the first drying plate; the robotic arm grabs the white cardboard from the second drying plate and feeds it into the second conveyor belt through the control component, and the second conveyor belt sends it out through the discharge port.

[0017] A further feature of this invention is that the control component includes a screw rotatably connected to the frame, a sliding block threaded onto the screw, a robotic arm fixedly connected to the sliding block, a drive motor fixedly connected to the end of the screw, the drive motor fixedly connected to the frame, a horizontal groove provided on the frame, the sliding block embedded in the groove and slidably connected to the groove.

[0018] By adopting the above technical solution, the robotic arm grasps both ends of the white cardboard, the drive motor controls the screw to rotate, and the control slider drives the robotic arm to move the white cardboard from the second drying plate to the second conveyor belt.

[0019] A further feature of this invention is that: a flattening roller is provided at the discharge port in the horizontal direction; a second cylinder is fixedly connected to the frame in the vertical direction; a portal frame is fixedly connected to the output end of the second cylinder; and the flattening roller is disposed in the portal frame and is rotatably connected to the portal frame.

[0020] By adopting the above technical solution, during the process of conveying white cardboard, the second cylinder controls the flattening roller to descend, shaping and flattening the white cardboard, thereby improving the production quality of white cardboard.

[0021] A further feature of this invention is that both the first drying plate and the second drying plate are provided with several strip grooves.

[0022] By adopting the above technical solution, it is convenient for moisture to drip off during the drying of white cardboard.
