Detailed Description
Example 1
The invention relates to a device for improving the dryness of paper web, which comprises a paper breaking detector, a support, a drying structure, an air supply structure and a control structure, wherein the drying structure is arranged on the upper side of the support, the drying structure is connected with the air supply structure, the air supply structure is connected with the control structure, and the control structure is connected with the drying structure and the paper breaking detector. The drying structure comprises an air beam, a heating air box and a mounting frame, wherein the air beam is installed on the lower side of the heating air box, the mounting frame is installed at two ends of the air beam, the mounting frame is installed on the support, an air outlet is formed in the air beam, and the heating air box is connected with an air supply structure through an air pipe. The air supply structure comprises a heater, an air feeder and a regulating valve, the heater is connected with a power supply, the heater is connected with the air feeder, the fan is connected with a heating air box through an air pipe, and a thermometer is installed on the air pipe. The control structure comprises a control cabinet, an electromagnetic valve and a cylinder, the control cabinet is connected with the electromagnetic valve through a control cable, the electromagnetic valve is connected with the cylinder through an air rod, and the cylinder is installed on the support and located on the lower side of the drying structure. The movable track is installed on the upper side of the support, a movable block is installed on the movable track, and an installation frame is installed on the movable block.
Two groups of hot air devices are added behind the sizing machine and at the position of a No. 93 cylinder, and hot air is taken from an air supply pipeline of the pre-coated MCB. The paper breaking detector transmits a paper signal to the PLC control cabinet through a detection cable, outputs a signal through a control cable to enable the electromagnetic valve to be electrified, and controls the cylinders on two sides to act through the air pipes, so that the air beams and the heating air boxes are close to the paper web when paper exists; meanwhile, the fan is started, hot air is delivered to the air box through the air pipe, moisture is taken away by the hot air, and the paper web is dried. The temperature of the hot air is accurately controlled by a thermometer and a regulating valve PID. The invention has the advantages of saving, low cost and effectively improving the dryness of the paper web.
The working principle of the invention is as follows: when the paper breaking detector of the sizing machine detects a paper signal, the signal is sent to the PLC control cabinet through the detection cable, the corresponding electromagnetic valve is electrified, the air source prompts the air cylinders on the two sides to act through the air pipes, so that the air beam (9) and the heating air box are close to the paper surface, and the paper web is dried in an auxiliary manner; when the electromagnetic valve is electrified, the fan is started to supply hot air, the temperature of the hot air is accurately controlled by the thermometer and the PID of the regulating valve, and the temperature can be set in the PLC control cabinet. Finally, the hot air reaching the surface of the paper web takes away the water to improve the dryness of the paper web. The invention has the advantages of saving, low cost and effectively improving the dryness of the paper web.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. While the invention has been described with reference to various components which are conventional in the art, it will be understood by those skilled in the art that the present invention is not limited to the details of the foregoing embodiments, which are provided to illustrate the principles of the invention and various changes and modifications which can be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
