DETAILED DESCRIPTION

[0021] like Figure 1-4 As shown, a die-cutting and slitting machine includes a machine body, on which a deviation correction controller 1 is arranged, one side of the deviation correction controller 1 is arranged with a positioning electric eye 2, the other side of the deviation correction controller 1 is arranged with an adjustable tensioning roller 3, the top of the deviation correction controller 1 is arranged with a deviation correction seat 4, both ends of the deviation correction seat 4 along the running direction of the printing material are arranged with guide rollers 5, and between the two guide rollers 5, two pressure sensors 6 installed on the deviation correction seat 4 for measuring the tension of the printing material are arranged.

[0022] The pressure sensor 6 can measure the tension on both sides of the printing material. The pressure sensor 6 transmits the pressure signal to the deviation correction controller 1, and the deviation correction controller 1 controls the tension roller 3 to adjust the tension on both sides of the printing material to ensure the normal subsequent printing.

[0023] The two ends of the adjustable tensioning roller 3 are respectively hinged with two adjusting cylinders 7, which are arranged on the deviation correction controller 1, the pressure sensor 6 signal is connected to the deviation correction controller 1, and the deviation correction controller 1 signal is connected to the adjusting cylinder 7; the two adjusting cylinders 7 can adjust the two ends of the tensioning roller 3 respectively, and the adjusting cylinders 7 can be adjusted according to the value of the pressure on both sides of the printing material.

[0024] A plurality of slide rails are arranged on the top of the correction controller 1, on which a slide seat 15 is slidably arranged, and the slide seat 15 is rotatably connected to the correction seat 4; when the positioning electric eye 2 detects that the position of the printed material is offset, the correction seat 4 corrects the printing material by sliding on the slide rails, so that the position of the printing material returns to the preset position.

[0025] A correction cylinder 16 is provided on the top of the correction controller 1, and the telescopic rod of the correction cylinder 16 is hinged to the correction seat 4; the direction in which the correction seat 4 slides depends on whether the telescopic rod of the correction cylinder 16 is extended or retracted. The correction controller 1 controls the operation of the correction cylinder 16 according to the deviation direction of the printed material detected by the positioning electric eye 2.

[0026] The deviation correction controller 1 is provided with a display screen 11 and control buttons 12 ; the display screen 11 is used to display parameter settings, and the parameters on the deviation correction controller 1 are set through the control buttons 12 .

[0027] The plurality of slide rails include a first slide rail 13 and a second slide rail 14, which are symmetrically arranged. At least one group of first slide rails 13 and second slide rails 14 is arranged on the top of the deviation correction controller 1; the deviation correction seat 4 moves on the slide rails, and the slide seat 15 is rotationally connected to the deviation correction seat 4. The deviation correction seat 4 rotates during the movement, and the position of the printed material is moved back to the set position by rotation.

[0028] During use, the printing material passes through the inner side of the tension roller 3, passes through two guide rollers 5, and then passes through the electric eye to enter the subsequent printing process. Two pressure sensors 6 respectively detect the pressure on both sides of the printing material.

[0029] However, in the process of correcting the position of the printing material, the correction seat 4 may also cause the pressure detected by the pressure sensor 6 to change. Therefore, in order to ensure that the tensioning roller 3 does not fall into invalid adjustment, the pressure difference between the two pressure sensors 6 is set to be maintained for a certain period of time before adjusting the position of the tensioning roller 3; and when the correction seat 4 moves, the tensioning roller 3 is not adjusted.

[0030] After the pressure difference between the two pressure sensors 6 lasts for a period of time, the telescopic rod of the regulating cylinder 7 on the side with smaller pressure retracts, and this end of the tensioning roller 3 moves inward, and the loose side of the printing material is tensioned, so that the tension on both sides of the printing material tends to be consistent.

[0031] The positioning electric eye 2 can locate the position of the printing material. When the printing material deviates to one side, the correcting seat 4 rotates to the deviated side, and brings the printing material back to the set position when the correcting seat 4 rotates.

[0032] This embodiment is suitable for the deviation correction of narrow-sized printing materials. The tension roller 3 is used to keep the printing material in a state suitable for printing, thereby improving the printing quality.

[0033] For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
