[0002] Generally, before printing a preselected customized trademark pattern on paper by a transfer method, an ink supply device in a printing machine generally needs to coat ink on an ink roller through an ink cartridge, and then the ink on the ink roller is transferred to a printing roller to complete the ink supply operation in cooperation with the entire printing machine.

[0003] According to the Chinese patent with the announcement number CN221022855U, an ink supply device of an intermittent relief trademark printing machine, comprising a main bracket, the inner side of the main bracket is fixedly connected with an inner bracket at the upper middle position, an ink cartridge is clamped at the lower left position in the inner bracket, and a sealing clamping seat is clamped at the upper left position of the ink cartridge, and the top end of the sealing clamping seat is provided with a combined cover frame through integral molding.

[0004] In the above scheme, the ink roller is used to supply ink to the printing roller body, which leads to the following shortcomings: when the ink supply device is used, the surface of the ink roller may have a local ink excess condition, which causes uneven ink distribution when the ink is transferred to the printing roller, thereby reducing the printing quality. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a pattern printing ink supply mechanism to solve the problem that when the ink supply device is used, the surface of the ink roller may have a local ink excess condition, which causes uneven ink distribution when the ink is transferred to the printing roller, thereby reducing the printing quality.

[0006] In order to achieve the above utility model purposes, the utility model adopts the following technical scheme: a pattern printing ink supply mechanism, comprising an ink cartridge, an ink inlet hole is formed in the top surface of the ink cartridge, an ink outlet hole is formed in the bottom surface of the ink cartridge, an ink roller is rotatably arranged in the ink outlet hole, a drive motor is fixed to the right side of the outer wall of the ink cartridge, the output shaft of the drive motor is fixedly connected with the right end of the ink roller, two support plates are fixed to the front side of the outer wall of the ink cartridge, a printing roller is rotatably arranged between the two support plates, the printing roller is in contact with the ink roller, a scraper is movably arranged below the ink roller, and an ink delivery pipe is detachably arranged above the ink cartridge.

[0007] Preferably, the bottom surface of the scraper is fixed with a collection box.

[0008] Preferably, a fixed plate is fixed to the rear side of the outer wall of the ink cartridge, an electric push rod is fixed to the bottom surface of the fixed plate, and one end of the telescopic rod of the electric push rod is fixedly connected with the top surface of the collection box.

[0009] Preferably, the top surface of the fixing plate is provided with two limiting holes, and the top surface of the collecting box is fixed with two limiting columns, which are respectively and slidably inserted into the two limiting holes.

[0010] Preferably, the ink cartridge and the ink delivery pipe are detachably provided with a connecting barrel, and the inside of the connecting barrel is fixed with a filter screen.

[0011] Preferably, the inner wall of the ink inlet hole is provided with a first internal thread, the bottom end of the connecting barrel is fixed with a fixing ring, the outer wall of the fixing ring is provided with a first external thread, the first external thread is threadedly connected with the first internal thread, the inner wall of the connecting barrel is provided with a second internal thread, the bottom end of the ink delivery pipe is fixed with a connecting ring, the outer wall of the connecting ring is provided with a second external thread, and the second external thread is threadedly connected with the second internal thread.

[0012] Compared with the prior art, the pattern printing ink supply mechanism has the following beneficial effects:

[0013] I. In use, the staff can supplement the ink in the ink cartridge through the ink delivery pipe. When the staff needs to supply ink to the printing roller, the drive motor is started first, so that the ink roller rotates in the ink outlet hole, and then the ink in the ink cartridge covers the surface of the ink roller. At this time, the excess ink can be scraped off by the scraper to prevent the ink roller surface from having too much ink locally and ensure that the ink on the ink roller surface is evenly distributed. At this time, the printing roller is in contact with the ink roller, and the ink on the ink roller is transferred to the surface of the printing roller through contact, thereby ensuring that the ink on the printing roller is evenly distributed during printing and improving the printing quality.

[0014] II. In use, when the scraper scrapes off the excess ink, the part of the ink is scraped into the collecting box below. The collecting box is convenient for the staff to collect and process the excess ink, avoiding waste of ink and environmental pollution. The collecting box can be adjusted in lifting by starting the electric push rod, and then the scraper can be adjusted in lifting, so that the distance between the scraper and the ink roller can be adjusted according to actual needs, thereby optimizing the ink scraping effect.

[0015] III. In use, the cooperation of the limiting hole and the limiting column is conducive to limiting the collecting box and the scraper, preventing deviation or shaking during lifting, and improving the stability. The cooperation of the connecting barrel and the filter screen is conducive to filtering when the ink delivery pipe delivers ink in the ink cartridge, ensuring the quality of the ink entering the ink cartridge and preventing impurities from affecting the printing quality. The cooperation of the fixing ring and the connecting ring is conducive to the staff to disassemble the connecting barrel and the filter screen, facilitating cleaning or replacement, and ensuring long-term stable operation of the equipment.
