Detailed Description
The technical solution of the present invention is further illustrated by the following specific examples.
As shown in fig. 1 and 2, the power source of the ink supply system with the planetary reduction cam device is a main shaft 2 with a duplicate gear, one end of the main shaft 2 is arranged in the machine frame, the other end of the main shaft 2 is supported by a gear shaft bracket 11, and shaft head covers 3 and 9 are arranged at two ends of the main shaft 2. The power source of the main shaft 2 is a duplicate gear adjacent to the main shaft. The central gear 10 rotates synchronously with the main shaft 2 through a flat key, preferably, the number of teeth of the central gear 10 is 40, the central gear 10 drives the pinion gears 14 to rotate, the number of the pinion gears 14 is 2-10, preferably, the number of the pinion gears 14 is 8, the number of the teeth of the pinion gears 14 is 20, the pinion gears 14 are freely sleeved on the pinion shaft 13, and the pinion shaft 13 is fixed in the shaft seat 16. The shaft seat 16 is sleeved on the main shaft 2 through a bearing, and a stop rod 17 is arranged below the shaft seat 16 to prevent the shaft seat 16 from rotating.
