Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 The utility model provides a technical solution: an automatic ink supply device for an offset printing machine, comprising a storage mechanism 1 and a uniform mechanism 2 assembled at the bottom of the storage mechanism 1, the storage mechanism 1 comprising an ink tank 101, a plurality of groups of ink supply tubes 102 are fixedly installed at the bottom of the ink tank 101 at equal distances, a plurality of groups of quantitative motors 3 are fixedly installed at the top of the ink tank 101 at equal distances, an output end of the quantitative motor 3 is fixedly installed with a shaft 301 that penetrates the ink tank 101 and extends to the ink supply tube 102, a quantitative reel 302 is fixedly installed at the bottom of the outer wall of the shaft 301, the uniform mechanism 2 comprises a processing cover 201, two groups of assembly grooves 203 are arranged on the front side of the inner wall of the processing cover 201, uniform scrapers 202 are fixedly installed inside the assembly grooves 203, a cleaning cover 204 is fixedly installed on the rear side of the processing cover 201, a cleaning motor 6 is fixedly installed on one side of the cleaning cover 204, a cleaning brush wheel 601 is fixedly installed on the output end of the cleaning motor 6 that penetrates the cleaning cover 204, and a recovery box 5 is arranged below the cleaning cover 204.

[0022] Based on the above-mentioned structural setting, the automatic ink supply device of the offset printing press is composed of a storage mechanism 1 and a uniform mechanism 2, wherein the storage mechanism 1 is an ink storage and quantitative discharge mechanism, with the help of the storage mechanism 1, the offset printing press can be automatically supplied with ink during operation, and the uniform mechanism 2 is a uniform processing mechanism during automatic ink supply. Specifically, during the working process, the ink tank 101 can store ink, and the ink supply tube 102 can discharge the ink stored in the ink tank 101, thereby realizing automatic ink supply operation for the offset printing press, and the quantitative motor 3 drives the quantitative reel 302 to rotate in the ink supply tube 102 through the shaft 301, and the rotation of the quantitative reel 302 can quantitatively discharge the ink in the ink tank 101 through the ink supply tube 102, thereby realizing accurate quantitative ink supply to the offset printing press and improving the accuracy of ink supply to the offset printing press. The processing cover 201 is installed on the printing plate of the offset printing press. The ink supply tube 102 penetrates the processing cover 201 to supply ink to the printing roller of the offset printing press. The two sets of uniform scrapers 202 are fixedly installed in the assembly groove 203 at the bottom of the processing cover 201, so that the ink injected into the printing roller through the ink supply tube 102 can be uniformly processed by the uniform scraper 202, thereby improving the uniformity of the device when supplying ink to the printing press and ensuring the quality of the offset printing press when printing products. The cleaning motor 6 drives the cleaning brush wheel 601 to rotate inside the cleaning cover 204 to clean the surface of the printing roller after printing is completed, thereby removing the residual ink on the surface of the printing roller, avoiding the situation where the residual ink on the printing roller affects the printing of subsequent products, and improving the stability of the offset printing press when printing products. The recovery box 5 can recycle the ink removed by the cleaning brush wheel 601, which is convenient for the staff to centrally process later.

[0023] Furthermore, two sets of heating rods 103 are fixedly installed at the lower part of the ink tank 101, and a display screen 106 used in conjunction with the heating rods 103 is fixedly installed on one side of the front of the ink tank 101. The heating rods 103 can heat and maintain the ink stored in the ink tank 101 at a constant temperature, so that the ink in the ink tank 101 is always kept at an optimal printing temperature of 20-28 degrees, and the display screen 106 can display the state of the heating rods 103 when it is in operation, so that the staff can observe and understand it.

[0024] Furthermore, multiple sets of vibration motors 401 are fixedly installed at equal distances on the front and back of the bottom of the ink tank 101, and a vibration rod 4 is fixedly installed at the output end of the vibration motor 401 through the ink tank 101. The vibration motor 401 drives the vibration rod 4 to vibrate the ink inside the ink tank 101, thereby avoiding the condensation of the ink in the ink tank 101 and improving the stability of the device when automatically supplying ink to the offset printing machine.

[0025] Furthermore, two groups of injection tubes 104 are fixedly installed on the rear side of the top of the ink tank 101. The injection tubes 104 facilitate the staff to add ink to the ink tank 101 later, thereby improving the uniformity of the staff when adding ink to the ink tank 101.

[0026] Furthermore, the bottom of the front and back sides of the cleaning cover 204 are fixedly mounted with a card sleeve 205, and the top of the front and back sides of the recycling box 5 are fixedly mounted with a card plate 501 used in conjunction with the card sleeve 205. The card plate 501 is inserted into the card sleeve 205 to mount the recycling box 5 on the bottom of the cleaning cover 204, so that the staff can dismantle and clean the recycling box 5 later.

[0027] Furthermore, two sets of fixing frames 105 are fixedly installed on the front and back of the bottom of the ink tank 101. The fixing frames 105 can support the front and back of the bottom of the ink tank 101, thereby improving the stability of the ink tank 101 during operation.
