[0002] With the development of the times, people pay more and more attention to clean energy and the research and development of clean energy equipment. Therefore, the processing and reuse of agricultural and animal husbandry wastes has also received more and more attention. Since most ordinary agricultural and animal husbandry wastes generally have the disadvantage of low calorific value, secondary processing of agricultural and animal husbandry wastes and improving the calorific value of agricultural and animal husbandry wastes can effectively improve the utilization efficiency of agricultural and animal husbandry wastes. The briquetting machine that extrude agricultural and animal husbandry wastes has also received more attention. The vertical ring die briquetting machine improved by this utility model is widely used in the processing fields such as biomass energy. It relies on the rotation of the ring die to drive the biomass material into the ring die and the pressure roller, and the biomass is made into a dense block, which can effectively improve the calorific value of agricultural and animal husbandry wastes. When the briquetting machine processes different biomasses, in order to adapt to the different physical properties of different biomasses, it is sometimes necessary to adjust the different die roller gaps to meet the processing needs; in addition, when processing biomass, the ring die and the pressure roller will produce greater wear during the working process, which will lead to an increase in the die roller gap, causing the production efficiency of the briquetting machine to drop sharply.

[0055] When the handle 7 is rotated counterclockwise, the handle 7 drives the adjusting shaft 14 to rotate, and then drives the secondary gear 15 to rotate counterclockwise, and drives the upper adjusting plate 16 to rotate clockwise through the main gear 20 meshing with the secondary gear 15, and the upper adjusting plate 16 drives the secondary adjusting plate 10 to rotate. The secondary adjusting plate 10 is subjected to the resistance of the pressure roller shaft 5 when rotating, and the pressure roller shaft 5 is further subjected to the thrust of the secondary adjusting plate 10. The upper adjusting plate 16 and the lower adjusting plate 18 are fixed together by the double adjusting plate main shaft sleeve 17, and then drives the secondary adjusting plate 10 on the lower adjusting plate 18 to apply thrust to the pressure roller shaft 5 at the same time. The pressure roller shaft 5 is constrained in the guide rail groove 3 of the upper plate 2 and the lower plate 12. When the pressure roller shaft 5 is subjected to the thrust, the pressure roller shaft 5 moves along the guide rail groove 3 to the side close to the ring die, so as to adjust the gap between the pressure roller 4 and the ring die.
