DETAILED DESCRIPTION

[0014] Reference Figures 1 to 4 The utility model is further described in detail.

[0015] A liquid three-roll grinding device comprises a frame 1, three groups of grinding rollers 2 located on the frame 1, a feeding device 3 located above the three groups of grinding rollers 2, and a stirring device 4 located on one side of the frame 1, wherein the feeding device 3 comprises a driving shaft 30 and two flip arms 31 located on the driving shaft 30, the tail end of the flip arm 31 is hinged with a swing arm 32, and the tail ends of the two swing arms 32 are detachably assembled on both sides of a barrel 33, when the driving shaft 30 drives the flip arm 31 to flip counterclockwise, the barrel 33 is in an ascending and lifting state until the outer wall of the barrel 33 contacts the driving shaft 30, so that the barrel 33 is flipped along the driving shaft 30 to complete the unloading, and a roller 34 is provided at the bottom of the barrel 33, and the stirring device 4 comprises a stirring shaft 40, and the barrel 33 can slide to the bottom of the stirring shaft 40.

[0016] The two side walls of the barrel 33 are provided with an assembly block 330 with a slot 331, and the side wall of the slot 331 is provided with a socket 1 332. The tail end of the swing arm 32 is provided with a U-shaped plug block 320, and the inner side wall of the plug block 320 is provided with a socket 2 321, and the outer side wall is provided with a socket 3 322. The outer side wall of the plug block 320 is also provided with a bracket 35, and a retractable positioning bolt is inserted into the bracket 35. When the inner wall end of the plug block 320 is fitted into the slot 331, the socket 1 332, the socket 2 321, and the plug block 320 are in a coaxial state, and the positioning bolt successively penetrates the socket 3 322 and the socket 1 332 of the plug block 320 until it is clamped in the socket 2 321. The positioning bolt includes a bolt column 323, a bolt head 324 at the front end, a bolt block 325 at the rear end, and a retaining ring 326 located in the middle of the bolt column 323. A spring 327 is also provided on the bolt column 232. One end of the spring 327 contacts the inner wall of the bracket 35, and the other end contacts the retaining ring 326. The spring 327 drives the retaining ring 326 to contact the outer wall of the plug block 320. The bolt block 325 includes a round block 328 integral with the bolt column 323, and two clamping blocks 329 distributed along the circumference of the round block 328. The bolt block 325 is adapted to the shapes of the slots 331 1, 331 2, and 331 3.

[0017] Working principle: the barrel 33 moves to the bottom of the stirring device 4 through the roller 34, and after the liquid in the barrel 33 is fully stirred by the stirring shaft 40, it moves to the feeding device 3 through the roller 34, and assembles the plug block 320 on the swing arm 32 with the assembly block 330 of the barrel 33. First, the positioning bolt is pulled to make the spring 327 contracted. At this time, the bolt block 325 is separated from the assembly block 330, which is convenient for the plug block 320 to be inserted into the slot 331 of the assembly block 330. At this time, the socket 1 332, the socket 2 321 and the socket 322 are in a coaxial state, and no force is applied to the positioning bolt. The positioning bolt drives the retaining ring 326 to move toward the socket 322 through the driving force of the spring 327, and at the same time drives the bolt block 325 to pass through the socket 1 332 until it is stuck in the socket 2 321 of the plug block 320, thereby realizing the fixed assembly of the swing arm 32 and the barrel 33. The drive shaft 30 is driven by the motor to rotate counterclockwise, driving the flip arm 31 to flip counterclockwise, and the barrel 33 is in an upward state until the outer wall of the barrel 33 conflicts with the drive shaft 30, and the flip arm 31 continues to operate, so that the barrel 33 flips along the drive shaft 30, so that the liquid material is poured onto the three sets of grinding rollers 2, and the automatic loading is completed. Such structural improvement enables the barrel 33 to immediately carry out the loading process after the mixing is completed, and through the cooperation of the loading device 3, fast loading is achieved, saving labor and improving production efficiency.
