DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] See also Figures 1 to 7 A roller device for ink printing comprises a mounting plate 1, a grip 5 and a placement plate 15. A print to be coated with ink is placed on the placement plate 15, and then the ink is brushed.

[0034] A moving plate 2 is slidably mounted inside the mounting plate 1, and a fixed roller assembly 3 and a moving roller assembly 4 are rotatably mounted on the mounting plate 1 and the moving plate 2, respectively.

[0035] The length of the whole formed by the mounting plate 1 and the movable plate 2 can be adjusted, and then the length of the whole formed by the fixed roller assembly 3 and the movable roller assembly 4 can be adjusted synchronously, so that the length of the components performing the printing activity can be changed, and the overall length of the equipment can be adjusted in a targeted manner according to actual needs, which is convenient for use and carrying and can avoid waste of ink.

[0036] The fixed roller assembly 3 can move on the movable roller assembly 4 .

[0037] A threaded rod 18 is rotatably mounted inside the mounting plate 1, a transverse bevel gear 19 is fixedly mounted on the threaded rod 18, a nut pair 20 is threadedly connected to the threaded rod 18, a connecting piece 21 is fixedly mounted on the nut pair 20, and the connecting piece 21 is fixedly connected to the moving plate 2;

[0038] When the threaded rod 18 rotates, the nut pair 20 will move on the threaded rod 18, and then the movable plate 2 can be driven to move along with the nut pair 20 through the connecting piece 21, so that the movable plate 2 can be moved inside the mounting plate 1, thereby realizing the change of the overall equipment length.

[0039] A vertical bevel gear 17 is rotatably mounted inside the mounting plate 1, a connecting rod 9 is fixedly mounted at the center of the vertical bevel gear 17, and a rotating block 10 is fixedly mounted on the connecting rod 9 which penetrates the mounting plate 1;

[0040] The vertical bevel gear 17 is in meshing relationship with the transverse bevel gear 19 .

[0041] When the rotating block 10 is rotated, the rotation of the rotating block 10 will cause the vertical bevel gear 17 to rotate, and the vertical bevel gear 17 is in meshing relationship with the transverse bevel gear 19, so it will drive the transverse bevel gear 19 to rotate, and the transverse bevel gear 19 is fixedly mounted on the threaded rod 18, so the threaded rod 18 will rotate.

[0042] The fixed roller assembly 3 and the movable roller assembly 4 have the same structure, but are installed in a staggered manner.

[0043] The fixed roller assembly 3 and the movable roller assembly 4 include a fixed plate 11 on which fixed strips 12 are evenly and equidistantly fixed in a circular shape. The fixed plate 11 also has mounting blocks 13 evenly and equidistantly fixed in a circular shape. Each mounting block 13 has an elastic pad 14 fixedly mounted thereon.

[0044] The fixing plate 11 and the elastic pad 14 are both made of porous materials that can absorb ink.

[0045] When the elastic pad 14 is not subjected to pressure from the fixed plate 11, the elastic pad 14 is in an expanded state. At this time, when the entire device comes into contact with the print, the elastic pad 14 and the fixed plate 11 are at the same height, so that ink printing activities can be performed.

[0046] The fixed plate 11 on the fixed roller assembly 3 is plugged into the corresponding fixed plate 11 on the movable roller assembly 4. The fixed plate 11 on the fixed roller assembly 3 and the fixed plate 11 on the movable roller assembly 4 are combined together to form an approximately cylindrical structure.

[0047] When the movable roller assembly 4 moves on the fixed roller assembly 3, the fixed plate 11 on the movable roller assembly 4 will move on the elastic pad 14 of the fixed roller assembly 3. Since the elastic pad 14 has a certain elasticity, the elastic pad 14 can be compressed smoothly, thereby realizing the plug-in fit between the fixed plate 11 on the fixed roller assembly 3 and the movable roller assembly 4.

[0048] The fixing plate 11 and the uncompressed elastic pad 14 form a cylindrical polygonal curved surface, thereby ensuring the ink printing effect.

[0049] The fixed plate 11 on the fixed roller assembly 3 is above the elastic pad 14 on the movable roller assembly 4, and the fixed plate 11 on the movable roller assembly 4 is above the elastic pad 14 on the fixed roller assembly 3. As the fixed plate 11 moves, the corresponding elastic pad 14 is in a compressed or rebound state.

[0050] A support rod 6 and a connecting block 7 are fixedly mounted on the ends of the mounting plate 1 and the movable plate 2 that are away from each other. When the support rod 6 and the connecting block 7 are in contact with the supporting surface, the fixed roller assembly 3 and the movable roller assembly 4 are in a suspended state.

[0051] When the equipment is not in use, the support rod 6 and the connecting block 7 are in direct contact with the contact surface. At this time, the fixed roller assembly 3 and the movable roller assembly 4 are suspended, and the parts containing ink will not directly contact the supporting surface, avoiding accidental marks left by the ink and ensuring the cleanliness of the printing process.

[0052] A limit slider 8 is fixedly mounted on the connecting block 7 , and two slide grooves 16 adapted to the two limit sliders 8 are provided on the placement plate 15 .

[0053] The size of the placement plate 15 can be specifically designed according to common print sizes.

[0054] When in use, the limit slider 8 can be placed in the slide groove 16, and then the handle 5 can be used to slide the entire device, and then the limit slider 8 slides in the slide groove 16, then the entire device can only move in a straight line, ensuring the consistency of the direction of the printing link, and the angle of the device and the pressure relationship with the print can be kept constant during the movement of the device, ensuring the uniformity and consistency of printing of various parts of the print.

[0055] The working process of the utility model is that when it is needed to be used, the overall length of the device is adjusted according to actual use requirements.

[0056] The rotating block 10 rotates, and then the vertical bevel gear 17 drives the horizontal bevel gear 19 to rotate, and then the threaded rod 18 rotates. When the threaded rod 18 rotates, the nut pair 20 drives the movable plate 2 to move through the connecting piece 21, so that the movable plate 2 can be moved inside the mounting plate 1, thereby realizing the change of the overall equipment length.

[0057] While the moving plate 2 moves, the moving roller assembly 4 moves synchronously.

[0058] The fixed plates 11 on the fixed roller assembly 3 and the movable roller assembly 4 and the uncompressed elastic pad 14 form a cylindrical-like polygonal curved surface, thereby ensuring the effect of ink printing.

[0059] When in use, the device is dipped in ink, and then the limit slider 8 is placed inside the slide groove 16. The entire device slides through the handle 5, and then the limit slider 8 slides inside the slide groove 16. The entire device can only move in a straight line to complete the ink printing activity.

[0060] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
