[0009] Figure 1 It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION

[0010] The present invention is further described below in conjunction with all the accompanying drawings. The preferred embodiments of the present invention are as follows: Figure 1 The transfer tension adjustment device for the coating dryer described in this embodiment includes a transfer frame 34 installed between the front-stage drying box and the rear-stage drying box, a transfer entry roller 35 is installed at the input end of the transfer frame 34, a transmission roller frame 36 is provided above the transfer frame 34, a suction fan is installed in the transmission roller frame 36, the bottom of the output end of the transmission roller frame 36 and the top of the output end of the transfer frame 34 are hinged by a hinge plate, and a tension cylinder 37 is provided at the hinge, the cylinder body of the tension cylinder 37 is hinged to the transfer frame 34, the piston rod of the tension cylinder 37 is tilted upward and hinged to the transmission roller frame 36, and an upper transmission roller assembly is installed at the bottom of the transmission roller frame 36; an intermediate roller group is installed at the center of the top of the transfer frame 34; a tension adjustment assembly is installed below the output end of the transfer frame 34, and an output pressure roller 38 is installed on the transfer frame 34 above the tension adjustment assembly.

[0011] The upper transmission roller assembly includes a front fixed roller 39 and a rear adjusting roller 40, wherein the front fixed roller 39 is installed at the bottom of the input end of the transmission roller frame 36. After installation, the front fixed roller 39 is driven by the corresponding front fixed roller motor. A roller plate is fixed to the bottom of the transmission roller frame 36 in the output direction of the front fixed roller 39, and a roller seat 41 is movably hinged on the roller plate. The rear adjusting roller 40 is installed at the lower part of the roller seat 41, and a roller seat cylinder is hinged on the top of the roller seat 41. The roller seat cylinder is hinged to the bottom of the transmission roller frame 36 upward.

[0012] The intermediate roller group includes an intermediate movable roller 42 and an intermediate fixed roller 43, wherein an intermediate roller rod is vertically fixed on the transfer frame 34 in the output direction of the rear adjusting roller 40, an intermediate hinge plate 44 is movably hinged on the intermediate roller rod, an intermediate roller plate cylinder is hinged on the transfer frame 34, the intermediate roller plate cylinder is hinged to the intermediate hinge plate 44, the intermediate movable roller 42 is installed on the upper part of the intermediate hinge plate 44, and the intermediate fixed roller 43 is installed on the transfer frame 34 in the output direction of the intermediate movable roller 42.

[0013] The tensioning adjustment assembly includes an intermediate output adjustment roller 45, an intermediate adjustment cylinder 46, and an intermediate roller adjustment seat 47, wherein one end of the intermediate roller adjustment seat 47 is hinged to the output end of the transfer frame 34, and the other end of the intermediate roller adjustment seat 47 is suspended, and the intermediate adjustment cylinder 46 is hinged to the bottom of the suspended end, and the other end of the intermediate adjustment cylinder 46 is tilted downward and hinged to the transfer frame 34; the intermediate output adjustment roller 45 is installed on the top of the suspended end.

[0014] When the tension of the paper / cloth in the front and rear drying boxes is kept at a good level (the tension remains consistent), the piston rod of the tension cylinder contracts, driving the movable end of the transmission roller frame upward, and the front fixed roller and the rear adjusting roller leave the paper / cloth and do not contact the paper / cloth;

[0015] The paper / cloth to be dried enters from the middle transfer roller, passes through the middle movable roller, middle fixed roller, and middle output adjustment roller, and then is output; the suction fan sucks air as needed to take away part of the heat on the paper / cloth, thereby preventing the paper / cloth from carbonizing;

[0016] When the tension of the passing paper / cloth needs to be fine-tuned (the adjustment force is small), the piston rod of the intermediate adjustment cylinder extends to drive the upper part of the movable end of the intermediate roller adjustment seat. When the intermediate roller adjustment seat moves upward, it simultaneously drives the intermediate output adjustment roller upward. When the intermediate output adjustment roller moves upward, it pushes up the paper / cloth, and the output pressure roller begins to contact the surface of the paper / cloth. Through the cooperation of the intermediate output adjustment roller and the output pressure roller, the paper / cloth is output in a step-by-step manner, thereby completing the fine-tuning of the tension of the paper / cloth;

[0017] When the traction difference between the front and rear of the drying process is large or the drying speed needs to be reduced, the piston rod of the tension cylinder extends to drive the movable end of the transmission roller frame downward, and the front fixed roller and the rear adjustment roller begin to contact the surface of the paper / cloth, and press the paper / cloth between the transfer roller and the middle movable roller downward to form a tension;

[0018] When it is necessary to tension and slow down again, the piston rod of the roller seat cylinder extends out, driving the rear adjusting roller to move downward again, and at the same time, the piston rod of the middle roller plate cylinder extends out, driving the middle hinge plate to move upward, so that the middle movable roller moves upward synchronously, and the paper / cloth is tensioned and slowed down again by the cooperation of the rear adjusting roller and the middle movable roller. The rear adjusting roller is driven by the corresponding roller motor, and the surface of the rear adjusting roller is provided with a concave and convex friction pattern, and the traction force of the rear adjusting roller on the paper / cloth is increased by the friction pattern; the above scheme can adjust the tension and conveying speed of the drying box in the front and rear sections, and at the same time, the heat on the surface of the paper / cloth can be absorbed by the suction fan, so as to prevent the carbonization of the paper / cloth, and the tension control effect is good, so that the quality of the dried paper / cloth is more stable.

[0019] The embodiments described above are only preferred embodiments of the present invention, and are not intended to limit the scope of implementation of the present invention. Therefore, all changes made based on the shape and principle of the present invention should be included in the protection scope of the present invention.
