[0035] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0036] Referring to Figures 1 to 2 , an independently adjustable feeding device for a roller mill is proposed. It is arranged on the machine body 1, and the machine body 1 has a feeding port 2. It includes a hopper 3, and the hopper 3 has a flaring part 4, a telescopic part 5, and a feeding part 6 arranged in sequence from top to bottom. The flaring part 4 is rotatably arranged relative to the machine body 1, the feeding part 6 is fixedly arranged relative to the machine body 1, and the feeding part 6 is located above the feeding port 2. Further, the cross-sections of the bottom end of the flaring part 4 and the feeding part 6 are both rectangular.

[0037] In this embodiment, in order to solve the problem that the feeding port 2 of the roller mill in the related art cannot be adjusted in angle and cannot adapt to different feeding directions, a hopper 3 is added to the machine body 1 of the roller mill. This hopper 3 is different from the conventional hopper 3, and a telescopic part 5 is designed in the middle. The telescopic part 5 is similar to a telescopic pipe and has the ability to expand and contract itself. Therefore, it can cooperate to realize the angle adjustment of the flaring part 4, and then can dock the feeding methods at multiple angles, solving the problem of not being able to adapt to different feeding directions and improving the flexibility and efficiency of material handling.

[0038] Further, it further includes a feeding adjustment member 7. The feeding adjustment member 7 is swingably or movably arranged relative to the machine body 1, is located between the feeding part 6 and the feeding port 2, the feeding adjustment member 7 abuts against the bottom end of the feeding part 6, the feeding adjustment member 7 has a plurality of material dropping ports 8 distributed at intervals, the material dropping ports 8 are located above the feeding port 2, and after the feeding adjustment member 7 swings or moves, the number of the material dropping ports 8 communicating with the feeding part 6 and the feeding port 2 increases or decreases.

[0039] Further, the feeding adjustment member 7 is swingably arranged relative to the machine body 1, the abutting surfaces of the feeding adjustment member 7 and the feeding part 6 are both arc-shaped surfaces, and it further includes a guiding track 9. The guiding track 9 is arranged on the machine body 1 and is located below the feeding adjustment member 7; a track wheel 10 is rotatably arranged on the feeding adjustment member 7 and is located on the guiding track 9. Further, the guiding track 9 is arc-shaped.

[0040] In this embodiment, an innovative feed regulating member 7 is introduced. This member can swing or move in front of the machine body 1 to flexibly adjust the material flow rate. The bottom of the regulating member closely adheres to the feed portion 6, and its surface is provided with a plurality of material dropping openings 8 with variable positions. These material dropping openings 8 are located above the feed opening 2. By the action of the regulating member, some of the material dropping openings 8 can be selectively opened or closed, thereby achieving fine control of the feeding rate. Further, the contact surfaces of the regulating member and the feed portion 6 are both designed in an arc shape to facilitate the smooth transition of the material. In addition, in order to guide the precise movement of the regulating member, a guiding track 9 and a track wheel 10 cooperating with it are added. The track is arranged in a specific arc to ensure the smoothness and stability of the adjusting action.

[0041] Furthermore, it further includes a bracket 11. The bracket 11 is arranged on the machine body 1 and is located on one side of the hopper 3; a rotating shaft 12 is rotatably arranged on the bracket 11, and a flaring portion 4 is arranged on the rotating shaft 12 to rotate therewith; a fixed shaft 13 is arranged on the bracket 11, and the feed portion 6 is arranged on the fixed shaft 13.

[0042] In this embodiment, a set of rotating mechanisms is designed for the flaring portion 4 of the hopper 3. Through the rotating shaft 12 supported by the bracket 11 installed on one side of the machine body 1, the flaring portion 4 can rotate together with the rotating shaft 12, realizing flexible adjustment of the material introduction angle. At the same time, the feed portion 6 maintains a static position through the fixed shaft 13 to ensure the stability of the feeding process.

[0043] Furthermore, the feed regulating member 7 further has a plurality of guiding portions 14, and the plurality of guiding portions 14 are respectively located between two adjacent material dropping openings 8. Further, the guiding portions 14 are in a semi-circular shape.

[0044] In this embodiment, the design of the guiding portions 14 is to prevent the material from accumulating on the feed regulating member 7. The semi-circular design can enable the material to slide down, pass through the material dropping openings 8 and enter the feed opening 2, further improving the guiding effect of the material flow.

[0045] Furthermore, it further includes a first connecting rod 15. The first connecting rod 15 is hinged on the inner wall at the bottom end of the flaring portion 4 and is inclined towards the central direction along the inner wall; a second connecting rod 16 is hinged on the inner wall of the feed portion 6 and is inclined towards the central direction along the inner wall; one end of a third connecting rod 17 is rotatably arranged on the first connecting rod 15, and the other end is rotatably arranged on the second connecting rod 16. Further, two of the first connecting rod 15, the second connecting rod 16 and the third connecting rod 17 are symmetrically arranged respectively.

[0046] In this embodiment, the designs of the first connecting rod 15, the second connecting rod 16, and the third connecting rod 17 are to shield the telescopic part 5 to prevent materials from hitting and damaging the telescopic part 5. Moreover, the hinged connections of the first connecting rod 15, the second connecting rod 16, and the third connecting rod 17 can cooperate with the rotation of the flared part 4 without interference. In addition, by setting the inclination direction of the first connecting rod 15, the materials can slide down along its surface instead of being stuck between the first connecting rod 15 and the inner wall, which improves the fluidity of the materials and prevents material jamming.
