Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model relates to a high-tension high-speed printing cutting device, as shown in figure 1, an integral frame of a cutting mechanism is composed of an air bag supporting baffle 2, a frame upper supporting baffle 15, a frame lower supporting baffle 17 and a frame wallboard 16, and the whole cutting station, namely the cutting device, is arranged at the upper part of the frame; the tension detection swing roller 14 is arranged on the frame wall plate 16 and used for providing a tension change signal for the material receiving motor to adjust the rotating speed of the motor, the tension detection swing roller 14 is pushed by the low-friction cylinder to detect the tension, and the air bag support 2 provides a stable air source for the low-friction cylinder;

the cutting device comprises a cutting frame, a cutter travelling mechanism is arranged on the cutting frame, the cutter travelling mechanism comprises a driving motor 3, the driving motor 3 drives a gear 4, the gear 4 displaces on a rack 5 so as to drive the cutting frame to move back and forth, and the cutting device travels through a rear limit 1 and a front and rear limit safety switch;

the cutting frame is internally embedded with a cutting walking support through a linear guide rail 10, a guide roller B18 is arranged between the cutting walking support and a frame wallboard 16, a cutting knife 12 is arranged on the cutting walking support, a cutting knife cylinder 11 is arranged on the cutting frame, the output end of the cutting knife cylinder 11 is connected with the cutting knife 12, the cutting knife 12 is connected with the surface of the frame wallboard 16 through a cutting compression roller 13, the cutting knife 12 is connected with the cutting compression roller 13 through a movable shaft, when a cutting control signal is detected, the compression roller cylinder 9 pushes the cutting walking support forwards along the linear guide rail 10, the cutting walking support pushes the cutting compression roller 13 to extrude to a new coiling shaft, and the cutting knife cylinder 11 pushes the cutting knife 12 to cut a coil of material, so that cutting is realized;

the cutter walking bracket is provided with a plurality of sliding blocks on the linear guide rail 10, so that impact deformation of the cutter frame during cutting action of a high-tension material can be eliminated;

the tension detection swing roller 14 adopts a lengthened swing arm to compensate and stabilize the tension of the printing part by the tension change caused by the fact that the material roll is changed from an old roll to a new roll when the material roll is cut at a high speed, and the printing overprinting printing quality can be improved only if the tension of the printing part is stable.

When the automatic winding machine is in actual use, after printing of the paper of the winding material is finished, the paper enters the cutting unit through the guide roller, the tension detection swing roller detects the tension and then rolls the paper, the linear speed of the whole machine is kept constant, the tension is stable, and the printing overprinting accuracy can be guaranteed only when the tension is stable; the winding diameter of the winding is gradually increased, the rotating speed of a motor is required to be gradually reduced, and the change trend of the motor speed is detected by a winding tension roller to provide a signal, so that the constant tension and the constant speed of the material roll are realized; when the old roll is increased to a set value, the old roll needs to be cut to a new roll, the diameter of the paper core of the new roll is small, the rotating speed of the driving motor of the new roll is very high, the change of tension is easily influenced by impact caused by changing the constant speed of the driving motor of the new roll into the variable speed at the moment of replacement, particularly, the material with large tension, such as thick paper with a large roll diameter, is very obvious under the condition of high speed, and the stability of the cut tension is directly influenced by the stability of the wound tension.
