Technical Field
[0001] The utility model relates to the technical field of printing machines, in particular to a limiting feeding mechanism of a semi-rotary printing machine. Background Art
[0002] Semi-rotary printing press is a common equipment in mechanical printing. The printing process is completed by the rotation of the printing wheel and the pressure of the printing on the material. Compared with other printing machines, semi-rotary printing press has the advantages of fast printing speed and high printing precision. It is widely used in packaging, labeling and other industries;
[0003] However, the traditional half-rotary printing machine still has some defects when in use. For example, there is no special limit and guide mechanism at the feed port of the half-rotary printing machine, and the printing paper will be tilted when feeding, so that the printing paper will rub against the side of the conveyor due to the tilt during transportation, which will cause the printing paper to be damaged and cause unnecessary losses. For this reason, we propose a limit feeding mechanism for a semi-rotary printing machine. Utility Model Content

[0024] Example:
[0025] See also Figure 1-5 , the utility model provides a technical solution of a limit feeding mechanism of a semi-rotary printing press: comprising a conveyor 1 and a feeding guide plate 2;
[0026] Frames are provided on the left and right sides of the conveyor 1. Four feed guide plates 2 are symmetrically provided at the four corners of the conveyor 1. Fastening bolts 3 are provided on the tops of the feed guide plates 2, and the fastening bolts 3 screw the feed guide plates 2 to the frame.
[0027] The feed guide plates 2 are symmetrically arranged on the front and rear sides of the conveyor 1, and a guide groove 7 is provided in the middle of the feed guide plates 2. A conveyor belt is provided on the conveyor 1, and the guide groove 7 is clamped on the edge of the conveyor belt.
[0028] A height limiting plate 6 is provided on the side of the top of the feed guide plate 2 facing the conveyor belt, the height limiting plate 6 extends above the conveyor belt, and the height limiting plate 6 covers the top of the guide groove 7;
[0029] Guide wheels 9 are equidistantly arranged in the guide groove 7, and the guide wheels 9 are inwardly close to the top surface of the conveyor belt;
[0030] A buffer spring 10 is provided at one end of the guide wheel 9 close to the feed guide plate 2, and a blocking panel 8 is installed in the guide groove 7. A through rectangular notch is provided at the position of the blocking panel 8 close to the guide wheel 9, so that the blocking panel 8 is sleeved on the guide wheel 9, and the blocking panel 8 is slidably installed in the guide groove 7;
[0031] An arc-shaped notch is formed at one end of the feed guide plate 2 away from the conveyor 1, and an adjustment groove 4 is formed in each of the arc-shaped notches. A mounting cavity 11 is formed at one side of the feed guide plate 2 close to the adjustment groove 4, and the adjustment groove 4 and the mounting cavity 11 are communicated with each other.
[0032] An electric push rod 12 and a guide plate 5 are installed in the installation cavity 11. The guide plate 5 is a rugby-shaped arc plate, and the guide plate 5 slides in the adjustment groove 4.
[0033] An electric push rod 12 is installed in the installation cavity 11, and the electric push rod 12 is connected to the guide plate 5;
[0034] When this solution is used, the feeding mechanism is docked at the feeding port of the printing machine. The printing paper will be tilted when feeding, resulting in inaccurate feeding and discharging positions, affecting the printing rate. In this solution, the feeding mechanism of the printing machine corrects the position of the feeding and discharging printing paper through the limiting effect.
[0035] Specifically, the guide groove 7 is clamped at the edge of the conveyor belt, and the height limiting plate 6 is abutted against the top of the conveyor belt. The printing paper is limited by the height limiting plate 6 so that the edges on both sides are more aligned, and the guide wheel 9 abuts against the top surface of the conveyor belt.
[0036] When the printing paper is fed, it is conveyed along the guide groove 7 and the conveyor belt, and the guide wheels 9 on both sides abut against the side edges of the printing paper. When the printing paper exerts a force on the guide wheel 9 due to its tilt, the buffer spring 10 contracts inwards for buffering. When the printing paper continues to be conveyed forward, the direction will be corrected by the guide wheel 9. At the same time, a blocking panel 8 is sleeved on the guide wheel 9 to block between the buffer spring 10 and the conveyor belt to prevent the printing paper from being twisted into the buffer spring 10.
[0037] The blocking panel 8 is movably connected to the guide groove 7. When the blocking panel 8 is subjected to force, it can also be retracted into the guide groove 7 and return to its initial position outward under the action of the buffer spring 10.
[0038] An adjustable guide plate 5 is arranged in the arc groove 4. The guide plate 5 is pushed by an electric push rod 12. The extension distance of the guide plate 5 is adjusted by the electric push rod 12. When the guide plate 5 is extended outward, the arc gap area of the feed guide plate 2 can be controlled, so as to adjust the inclination of the printing paper during feeding. The arc gap can be flexibly filled by extending the guide plates 5 on both sides, which is very convenient.
[0039] Likewise, a feed guide plate 2 is also provided at the discharge port of the conveyor 1, so that the output situation can be corrected again when entering the printing press.
