Detailed Description

The following describes specific embodiments of the present invention.

As shown in fig. 1, 2 and 3, the adjustable knife grinder comprises a stand 1, a guide seat 102 is integrally formed at the top of the stand 1, the cross section of the guide seat 102 is in a rectangular frame structure, two opposite sides of the guide seat 102 are respectively provided with an upper guide groove 5, a guide plate 101 is further connected to one side of the stand 1 below the guide seat 102, a pair of lower guide grooves 14 are formed on the guide plate 101, the lower guide grooves 14 are symmetrically arranged with the stand 1 as a center, and scales are arranged on the surfaces of the upper guide grooves 5 and the lower guide grooves 14. The pair of motors 2 are arranged on the inner side of the guide plate 101, each motor 2 is connected with one end of the grinding wheel shaft 4 through a motor connecting shaft 9 and a motor connecting bolt 10, the other end of the grinding wheel shaft 4 penetrates through the bearing 8 and is matched with the grinding wheel 3, each bearing 8 is positioned in the guide seat 102, and the grinding wheel 3 is a conical grinding wheel. A plurality of guide shafts 7 screwed with guide fixing nuts 6 extend into the upper guide grooves 5 and are integrally connected with the bearings 8, and a plurality of guide shafts 7 screwed with the guide fixing nuts 6 extend into the lower guide grooves 14 and are integrally connected with the motor 2; as shown in fig. 1 and 4, the opposite sides of the pair of motors 2 are respectively abutted against third links 1203, one end of each third link 1203 is hinged to one end of one second link 1202, and the other end of each second link 1202 is hinged to both ends of one first link 1201; the adjusting screw 11 penetrates the first link 1201, and an adjusting nut 13 for adjusting the up-down position of the first link 1201 is further screwed to the first link 1201.
