One end of the ink supply roller, the ink distribution roller group and the printing roller passes through the support plate facing the driving motor and is equipped with a driven gear, which cooperates with the meshing gear on the support plate for continuous driving.

[0007] Preferably, the front end of the support frame is provided with a strip-shaped opening for placing a material receiving tray.

[0008] Preferably, a supporting seat for mounting the ink cartridge is welded on the inner side of the support plate.

[0009] Preferably, a fixed shaft for assembling meshing gears is also welded on the support plate facing the drive motor.

[0010] Preferably, an opening is provided at the inner upper end of the ink cartridge for facilitating installation of an inking roller, and L-shaped fixing pieces are welded on both sides of the ink cartridge.

[0011] Preferably, the ink distribution roller group consists of five roller bodies.

[0012] Preferably, the output end of the driving motor is connected to a chain, and the driving motor and the inking roller are connected via the chain.

[0013] Preferably, a flip cover is installed on one end of the dust cover close to the ink cartridge via a hinge.

[0014] The beneficial effects of the present invention are as follows: the ink distribution roller group in the present invention ensures that the ink is evenly distributed during the entire transmission process, thereby improving the printing quality; the installation structure of the supporting frame ensures the stability of the entire system, reduces the risk of failure, and can improve the efficiency and stability of ink delivery through the cooperation of the driving motor with the driven gear and meshing gear.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0024] Example

[0025] An ink hopper for a full-wheel transfer printing machine, such as Figure 1-7 As shown, it includes an ink hopper body 1 , a dust cover 2 installed above the ink hopper body 1 , and a dust cover 3 installed on the side of the ink hopper body 1 .

[0026] The ink hopper body 1 includes a support frame 11, a material receiving tray 12 inserted under the support frame 11, support plates 13 fixedly installed on both sides above the support frame 11, an ink cartridge 14 fixed at the front end of the support plate 13, an inking roller 15 located inside the ink cartridge 14 and assembled with the support plate 13 at both ends, an ink leveling roller group 16 assembled in the middle part of the support plate 13 and in contact with the inking roller 15, a printing roller 17 assembled at the rear end of the support plate 13 and in contact with the ink leveling roller group 16, an auxiliary frame 18 fixedly installed on one side of the support frame 11, and a drive motor 19 installed on the auxiliary frame 18. One end of the inking roller 15, the ink leveling roller group 16 and the printing roller 17 pass through the support plate facing the drive motor 19 and are equipped with a driven gear to cooperate with the meshing gear on the support plate for continuous drive.
