Description

Technical Field

[0001] The present invention belongs to the technical field related to paper production equipment, and more specifically, particularly relates to a drying system and a drying method for papermaking. Background Art

[0002] During the papermaking process, paper contains a lot of water. Drying is mainly to reduce the water content of paper to a suitable level to meet the quality requirements of paper, such as strength, flatness, printing adaptability, etc. The appropriate moisture content can prevent problems such as mold and deformation of paper during storage and use.

[0003] During the paper production process, burrs may appear on the edge of the paper due to certain factors. After drying, the paper may need to be deburred by other equipment. However, it takes a certain amount of time to transport the paper to other equipment, which affects efficiency to a certain extent. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a drying system for papermaking to solve the technical problem in the prior art that after drying, the paper may need to be deburred by other equipment, but it takes a certain amount of time to transport the paper to other equipment, which affects the efficiency to a certain extent.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a drying system for papermaking, including a frame, a box body is connected to the frame, one end and the other end of the frame are rotatably connected to a rod body, one end and the other end of two groups of the rod bodies are connected to sprockets, multiple groups of sprockets are meshingly connected to mesh belts, one end of the frame is equipped with a motor, the motor is connected to a group of rod bodies, one end of the box body is equipped with a hot air blower, one end of the hot air blower is connected to a pipe group, the pipe group passes through the box body, one end of the pipe group is connected to multiple groups of nozzles, the box body is rotatably connected to two groups of threaded rods, the two groups of threaded rods are threadedly connected to blocks, the two groups of blocks are provided with grooves, and the two groups of grooves are movably penetrated by cutting components.

[0006] As a preferred technical solution of the present invention, a door body is hinged at one end of the box body, the two groups of blocks are threadedly connected with bolts, and the two groups of bolts are respectively threadedly connected to the corresponding cutting components.

[0007] As a preferred technical solution of the present invention, one end of the two groups of threaded rods are connected to a hand wheel.

[0008] As a preferred technical solution of the present invention, the box body is connected with two groups of round rods, and the two groups of round rods are respectively slidably connected to the corresponding blocks.

[0009] As a preferred technical solution of the present invention, the box body is rotatably connected with multiple groups of rollers, and the multiple groups of rollers are in contact with the mesh belt.

[0010] As a preferred technical solution of the present invention, one end of the two groups of bolts are connected to a knob.

[0011] The present invention provides a drying system for papermaking, which has the following beneficial effects:

[0012] 1. The new type cooperates with the threaded rod, the motor and the mesh belt. First, the two sets of threaded rods are rotated respectively to accurately adjust the positions of the two sets of cutting components until they can fit closely with the edge of the paper. Since the fibers inside the wet paper are saturated with more water, the fibers at this time are in a relatively soft state and have a certain degree of plasticity. When faced with the task of trimming burrs, such as using tools such as scrapers, the fibers of the wet paper can be smoothed more easily or removed smoothly, and will not break easily during the trimming process like dry paper. Then, the motor is started, and the sprocket and the mesh belt are driven by the rod body to engage with each other, thereby realizing the stable transportation of the paper. Before the paper is transported to the drying stage, the burrs on its edge will first contact the cutting component, so that the burrs on the edge of the paper can be removed smoothly. Such an operation process largely avoids the cumbersome process of transporting the paper to other specialized deburring equipment for processing, effectively saving time and labor costs, and thus significantly improving the overall production efficiency to a certain extent.

[0013] 2. Through the coordination between the bolts, blocks and cutting components, first open the door and unscrew the bolts that fix the cutting components. After the bolts are completely unscrewed, smoothly pull out the old cutting components and carefully check whether there are any impurities remaining in the tank. If there are, clean them up in time to provide good basic conditions for the installation of the new cutting components. Then, put the new cutting components into the tank accurately, align the bolts with the screw holes and screw them in step by step. The bolts fix the cutting components in the tank. Through this convenient operation method, the replacement of the cutting components can be completed in a short time, which improves production efficiency, enables the equipment to quickly return to the best working state, continuously and stably handles the burrs on the edge of the paper, and further guarantees the quality and progress of paper production and processing.
