[0038] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0039] like Figures 1 to 6 As shown, the embodiment of the present invention provides a pneumatic ink-distributing roller for printing production of easy-open cover sheets, comprising:

[0040] Printing machine body 1;

[0041] A mounting frame 2, the mounting frame 2 is welded and mounted on a side surface of the printing machine body 1;

[0042] The ink transfer wheel 3 and the water transfer wheel 4 are rotatably mounted inside the printing machine body 1;

[0043] PS plate wheel 5, PS plate wheel 5 is rotatably mounted inside the printing machine body 1;

[0044] The ink distribution mechanism 6 is respectively provided on the surface of the printing machine body 1 and the mounting frame 2, and is used to achieve an axial ink and water distribution effect, so that the ink and water are mixed more evenly;

[0045] The adjusting mechanism 7 is respectively arranged on the surface of the printing machine body 1 and the mounting frame 2, and is used to adjust the distance between the ink distribution mechanism 6 and the ink transfer wheel 3 and the water transfer wheel 4.

[0046] The ink transfer wheel 3 and the water transfer wheel 4 can transfer ink and water to the string roller 604 in the ink distribution mechanism 6, and then cooperate with the PS plate wheel 5 to perform printing.

[0047] like Figure 3 As shown, the ink uniformity mechanism 6 includes a stringing roller 604, which is arranged inside the printing machine body 1. A sliding block 601 is slidably installed on the surface of the upper groove of the mounting frame 2. A connecting block 602 is installed in the inner cavity of the sliding block 601. The axial end of the connecting block 602 is slidably connected in the inner cavity of the sliding block 601. One end of the connecting block 602 is snap-fitted and installed in the inner cavity of the stringing roller 604. The stringing roller 604 is rotatably connected on the connecting block 602. A bearing 603 is embedded in the outer surface of the connecting block 602. The bearing 603 is embedded in the inner cavity of the stringing roller 604.

[0048] The connecting block 602 is a setting with two discs connected to an axis, and the outer disc has the same diameter as one end of the stringing roller 604, and the other disc matches the size of the inner cavity of the stringing roller 604, so that the stringing roller 604 can be stuck in the connecting block 602 without affecting the rotation. A bearing 603 is embedded in the axis of the connecting block 602, and the outer surface of the bearing 603 is embedded in the inner cavity of the stringing roller 604, thereby enhancing the connectivity between the stringing roller 604 and the connecting block 602 and making the rotation between the stringing roller 604 and the connecting block 602 smoother.

[0049] like Figure 3 and Figure 5 As shown, a cylinder 605 is fixedly installed at one end of the connecting block 602 inside the stringing roller 604, a hard tube 606 is installed at the air inlet of the cylinder 605, and the other end of the hard tube 606 is arranged on the outside of the stringing roller 604 and is installed with a hose 609, an electromagnetic valve 610 is installed on the surface of the lower groove of the mounting frame 2, and the hose 609 passes through the middle groove of the mounting frame 2 and is connected to the air inlet of the electromagnetic valve 610.

[0050] One end of the hose 609 is connected to the hard tube 606, and the other end is installed on the electromagnetic valve 610. By adjusting the electromagnetic valve 610, the reciprocating speed of the cylinder 605 can be adjusted.

[0051] like Figure 5 As shown, a limit block 607 is welded and installed on the working end of the cylinder 605, a cross block 608 is welded and installed on the inner surface of the stringing roller 604, the working end of the cylinder 605 is slidably connected in the cross block 608, a gear 611 is meshed and installed in the inner cavity of the stringing roller 604, and a pulley 612 with a shaft is welded and installed on one end of the gear 611.

[0052] When the cylinder 605 is working, the limit block 607 at the working end will touch the cross block 608 welded and installed on the inner cavity surface of the stringing roller 604. The reciprocating extension and contraction of the working end of the cylinder 605 causes the stringing roller 604 to move back and forth. At the same time, the axial end of the connecting block 602 is slidably connected in the cavity of the sliding block 601. The hose 609 is a telescopic tube and will not affect the normal reciprocating motion of the stringing roller 604.

[0053] like Figure 2 and Figure 4 As shown, a clamping block 613 is slidably connected in the upper groove opened in the printing body 1, and two clamping blocks 613 are provided. The shaft ends of the shaft pulley 612 are rotatably connected in the two clamping blocks 613. A sliding plate 77 is slidably installed in the lower groove opened in the printing body 1, and a motor 614 is installed on the upper surface of the sliding plate 77. A shaftless pulley 615 is fixedly installed on the working end of the motor 614. The clamping block 613 is connected to the shaftless pulley 615 through a belt 616 to form a transmission connection.

[0054] The clamping block 613 clamps the shaft end of the shaft pulley 612 without affecting the rotation of the shaft pulley 612. The motor 614 can drive the shaft pulley 612 to rotate through the shaftless pulley 615 and the belt 616. At the same time, the inner cavity of the stringing roller 604 is meshed with the gear 611, so that the stringing roller 604 can rotate. The gear 611 has a certain length, and the stringing roller 604 will not affect the reciprocating motion when rotating.

[0055] like Figure 1 and Figure 5 As shown, the adjustment mechanism 7 includes a spring 71, one end of which is welded and mounted on the surface of the sliding block 601, and the other end of the spring 71 is welded and mounted on the surface of the upper groove of the mounting frame 2. A threaded rod 72 is threadedly connected in the upper groove of the mounting frame 2, and a twisting block 73 is fixedly mounted on one end of the threaded rod 72.

[0056] Spring 1 71 is always in an extended state, so that when the ink transfer wheel 3 and the water transfer wheel 4 transfer ink and water to the stringing roller 604, it has a certain buffering effect, ensuring uniform ink and water transfer. By turning the screw block 1 73, the threaded rod 1 72 can be adjusted so that the threaded rod 1 72 presses against the solenoid valve 610 to adjust the distance between the stringing roller 604 and the ink transfer wheel 3 and the water transfer wheel 4.

[0057] like Figure 3 and Figure 6 As shown, a spring 2 76 is welded and installed on one side surface of the clamping block 613, and the other end of the spring 2 76 is welded and installed on the upper groove surface of the printing body 1. A threaded rod 2 74 is threadedly connected in the upper groove of the printing body 1, and a twisting block 2 75 is fixedly installed on one end of the threaded rod 2 74.

[0058] Spring 2 761 is always in an extended state, so that when the ink transfer wheel 3 and the water transfer wheel 4 transfer ink and water to the stringing roller 604, it has a certain buffering effect, ensuring uniform ink and water transfer. The number of turns of twisting block 2 75 and twisting block 1 73 is the same, ensuring the same movement of the two ends of the stringing roller 604.

[0059] like Figure 4 As shown, a threaded rod 3 78 is threadedly connected in the lower groove of the printing machine body 1, and a twisting block 3 79 is fixedly installed at one end of the threaded rod 3 78.

[0060] The threaded rod 3 78 is rotated by turning the block 3 79 to adjust so that the shaftless pulley 615 and the shafted pulley 612 are in the same straight line.

[0061] In the embodiment of the present invention, first, by rotating the same number of twisting blocks 1 73, 2 75 and 3 79, the sliding block 1 601, the clamping block 613 and the sliding plate 77 are adjusted respectively by using the threaded rod 1 72, the threaded rod 2 74 and the threaded rod 3 78, wherein the solenoid valve 610 and the clamping block 613 can adjust the distance between the string roller 604 and the ink transfer wheel 3 and the water transfer wheel 4, and the sliding plate 77 can make the shaftless pulley 615 and the shafted pulley 612 in the same straight line without affecting the normal rotation of the motor 614. When mixing ink and water, first turn on the motor 614. The motor 614 can drive the shaft pulley 612 to rotate through the shaftless pulley 615 and the belt 616. At the same time, the inner cavity of the stringing roller 604 is engaged with the gear 611 to rotate the stringing roller 604, so that the surface of the stringing roller 604 is smeared with ink and water. Then open the solenoid valve 610 and adjust the solenoid valve 610 to a suitable speed. The limit block 607 at the working end of the cylinder 605 touches the cross block 608, pushing the stringing roller 604 to slide repeatedly, so that the ink and water are evenly distributed.

[0062] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
