[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figures 1-4 The lubrication mechanism of the printing plate roller of the gravure printing machine for test papers shown includes:

[0030] The control panel 001 is used to support the equipment. The interior of the control panel 001 includes two columns 101, which are distributed relatively to each other.

[0031] The lubrication mechanism 002 is installed above the operating table 001 and is used to keep the equipment lubricated when it is running at high speed. There are two lubrication mechanisms 002, which are distributed opposite to each other. The interior of the lubrication mechanism 002 includes an oil scraper 205, which is made of soft material.

[0032] The adjustment mechanism 003 is installed on the outside of the lubrication mechanism 002 and is used for quick installation and removal of the printing roller. There are two adjustment mechanisms 003, which are symmetrically distributed with the operating table 001 as the central axis. The lubrication mechanism 002 reduces wear on the printing press during the printing process.

[0033] Two columns 101 are fixedly connected to the top of the operating table 001. A long shaft 102 is detachably connected between the two columns 101. A roller body 103 is rotatably connected to the outer wall of the long shaft 102. Gears 104 are fixedly connected to both ends of the roller body 103. An ink tank 105 is fixedly connected to the top of the operating table 001. The ink tank 105 is located directly below the roller body 103. Ink is injected into the ink tank 105. When the roller body 103 rotates, it can be dipped in ink.

[0034] A housing 201 is fixedly connected above the operating table 001. A motor 202 is fixedly connected inside the housing 201. A gear 203 is fixedly connected to the output end of the motor 202. An oil groove 204 is opened inside the housing 201. The motor 202 drives the gear 203 to rotate, thereby driving the gear 104 to rotate, which in turn drives the roller body 103 to rotate.

[0035] Both sides of the inner wall of the housing 201 are fixedly connected with oil scraping brushes 205. The oil scraping brushes 205 cooperate with gear 203, and gear 203 meshes with gear 104. The side of the housing 201 is detachably connected with an oil cap 206. The oil scraping brushes 205 can scrape off excess oil, so that when the oil scraping brushes 205 mesh with gear 104, the wear during printing is reduced.

[0036] A telescopic rod 301 is slidably connected to the end of the long shaft 102. A spring 302 is fixedly connected to the end of the telescopic rod 301. A handle 303 is fixedly connected to the top of the telescopic rod 301. The telescopic rod 301 slides in the groove 304 to compress the spring 302, so that the telescopic rod 301 is far away from the groove 305, and the long shaft 102 and roller body 103 are replaced.

[0037] The side wall of the long shaft 102 is provided with a sliding groove 304, and the handle 303 cooperates with the sliding groove 304. The side of the column 101 is provided with a slot 305, which cooperates with the telescopic rod 301. The telescopic rod 301 is locked with the slot 305 to complete the quick installation.

[0038] The working principle of this utility model is as follows: When the power is turned on, the oil cap 206 is opened to inject oil into the interior. The drive motor 202 drives the gear 203 to rotate. The oil scraper 205 scrapes off the excess oil. The gear 203 drives the gear 104 to rotate, thereby enabling the gear 104 to drive the roller body 103 to maintain good operation, reduce wear, and extend service life. When it is necessary to replace the long shaft 102, two people are required to operate it. The handle 303 is slid in the slide groove 304 to compress the spring 302 inside the long shaft 102, so that the telescopic rod 301 is away from the groove 305. Then, a new long shaft 102 can be replaced. The handle 303 is slid in the slide groove 304 to place the long shaft 102 between the two columns 101, so that the telescopic rods 301 at both ends of the long shaft 102 are locked with the grooves 305 on the side walls of the columns 101.
