The bottom welding of loop bar 4 has slider 301, has seted up on the roof of third support column 3 with slider 301 assorted second spout 302, through slider 301 and the second spout 302 that sets up for loop bar 4 is more stable when the roof of third support column 3 rotates, is difficult for empting, thereby has increased the life of device.

The extrusion mechanism comprises an expansion link 505 and a spring 506, the spring 506 is movably sleeved on the outer surface of the expansion link 505, two ends of the expansion link 505 and two ends of the spring 506 are respectively welded on the lower surface of the sliding rod 504 and the bottom wall of the first cavity 501, and through the arrangement of the printing roller 101, the fixed roller 201 and the pressing roller 6, the paper slides on the lower surface of the printing roller 101, the upper surface of the fixed roller 201, and the lower surface of the pressure roller 6, driven by the outer paper receiving device, the paper applies a pressing force to the pressure roller 6, the slide bar 504 is pulled to slide downwards by the resilience of the spring 506 inside the fixed block 5, thereby driving the pressure roller 6 to extrude the paper, avoiding that the printing roller 101 extrudes the paper in the using process and brings a vertical force to the paper, thereby drive the paper and take place small displacement in vertical, produce the condition of fold, greatly reduced the emergence of fold.

The lifting mechanism mainly comprises a threaded rod 507 and a threaded groove 401, the threaded rod 507 is welded on the top wall of the second cavity 502, the threaded groove 401 is arranged on the inner wall of the sleeve rod 4, the threaded rod 507 is in threaded connection with the threaded groove 401, the rotating handle 402 is pushed through the arranged lifting mechanism to drive the sleeve rod 4 to rotate, so that the sleeve rod 4 is driven to slide up and down on the outer surface of the threaded rod 507, the extending length of the sleeve rod 4 is further adjusted, when printing paper with different strengths, the pressing roller 6 is moved upwards when the sleeve rod 4 is extended, the angle between the upper surface of the fixed roller 201 and the lower surface of the pressing roller 6 is reduced, so that the pressure of the pressing roller 6 on the paper is reduced, otherwise, the height of the pressing roller 6 is reduced, the pressure on the paper is increased, when the extrusion force of the paper on the pressing roller 6 is too small, the pressing roller 6 cannot be pressed upwards, and the spring 506 cannot, the pressing roller 6 is regulated to move downward by rotating the sleeve lever 4, thereby stretching the spring 506, and the pressing of the pressing roller 6 against the sheet is increased by the repulsive force of the spring 506.

The welding has rotating handle 402 on the surface of loop bar 4, through the rotating handle 402 who sets up to be convenient for rotate loop bar 4, and then control loop bar 4 and slide from top to bottom at the surface of threaded rod 507, reach the effect that the length was stretched out to regulation loop bar 4.

The lower surface of the printing roller 101 and the upper surface of the fixing roller 201 are on the same horizontal plane, and the lower surface of the printing roller 101 and the upper surface of the fixing roller 201 are arranged on the same horizontal plane, so that the printing roller 101 can perform rolling printing on paper conveniently.

The vertical axis homogeneous phase coincidence of third support column 3, loop bar 4 and fixed block 5 through the vertical axis homogeneous phase coincidence setting with third support column 3, loop bar 4 and fixed block 5, has increased the stability of device to the life of device has been improved.

The working principle is as follows: driven by the outer paper receiving device, the paper slides on the lower surface of the printing roller 101, the upper surface of the fixed roller 201 and the lower surface of the pressure roller 6, in the sliding process, because of the inclination angle between the upper surface of the fixed roller 201 and the lower surface of the pressure roller 6, the paper has an extrusion force on both the upper surface of the fixed roller 201 and the lower surface of the pressure roller 6, the pressure roller 6 is extruded to move upwards, the pressure roller 6 moves upwards to drive the sliding rod 504 to slide upwards, thereby extending the spring 506, the rebound force generated by the spring 506 presses the paper through the slide bar 504 and the pinch roller 6 until the stress is balanced, thereby the pressure roller 6 always extrudes the paper, the paper is prevented from being extruded by the printing roller 101 in the using process, a vertical force is brought to the paper, thereby drive the paper and take place small displacement in vertical, produce the condition of fold, greatly reduced the emergence of fold.

When printing the paper of different intensity, thereby promote turning handle 402 and drive loop bar 4 and rotate, the diapire of loop bar 4 rotates on the roof of third support column 3, the inside thread groove 401 of loop bar 4 slides from top to bottom at the surface of threaded rod 507, and then reached the effect of adjusting loop bar 4 and stretching out length, rebound pinch roller 6 during extension loop bar 4, the angle between the upper surface of fixation roller 201 and the 6 lower surfaces of pinch roller has been reduced, thereby the pressure of pinch roller 6 to the paper has been reduced, otherwise, reduce the height of pinch roller 6, the pressure to the paper has been increased.

When the extrusion force of the paper to the pressing roller 6 is too small, the pressing roller 6 cannot be extruded to move upwards, and therefore the spring 506 cannot be stretched, the pressing roller 6 is adjusted to move downwards through the rotating sleeve rod 4, so that the spring 506 is stretched, and the extrusion force of the pressing roller 6 to the paper is increased through the resilience force of the spring 506.
