This application does not improve upon commercially available sugarcane pressing machines, and the existing specific structure is not described in detail here.

[0034] The feed roller 1 includes: a roller body 111 and toothed protrusions 11; multiple toothed protrusions 11 are arranged in an array on the surface of the roller body 111; an inclined surface 142 is provided on the side of the toothed protrusions 11 facing the pressing chamber 3; a cutting end face 141 is provided on the side of the toothed protrusions 11 away from the pressing chamber 3; the cutting end face 141 is arranged perpendicular to the top surface of the toothed protrusions 11. This arrangement can reduce the speed at which the material passes through the pressing chamber 3, increase the area and depth of material pressing, extend the time of entering the roller, and improve the juicing efficiency.

[0035] Flange guide plates 2 are respectively provided on both ends of the top roller 23; the diameter of the flange guide plate 2 is larger than the cross-sectional diameter of the top roller 23, thereby realizing the directional guidance of the material entering the pressing chamber 3, preventing the material from being hoisted into the gap between the frame and the top roller 23 or getting stuck, and fully extracting sugarcane juice. The flange guide plate 2 can also guide the flow inside the juicer.

[0036] In one specific embodiment, the flange guide plate 2 is accommodated between the frame and the top roller 23.

After adjustment, the volume of the pressing chamber 3 can be controlled to ensure that the squeezing force of the sugarcane between adjacent pressing rollers meets the production requirements. The specific structure and installation position are the same as those of commonly used sugarcane presses, and will not be described in detail here.

[0047] In one specific embodiment, the outer diameter of the roller body 111 of the lower feed roller 1 is φ800mm.

[0048] The device was fabricated by replacing the fixed flange of the top roller of the press with a large flange that integrates with the top roller. Using spare parts for the top roller of the No. 1 press at the Jingzhen Sugar Factory, 10-M42 screw holes were made at both ends of the press roller to create a large flange that mates with it. A 20mm thick stainless steel fishtail plate was designed and manufactured. This solved the problem of residue trapping in the fixed flange and eliminated safety hazards.

[0049] The old shaft sleeve of the ordinary feed roller of the press was replaced with a high-efficiency toothed feed roller with better roller feeding effect, and then installed. The new high-efficiency toothed feed roller is made of cast steel with an outer diameter of φ800mm and includes comb plates and comb plate adjustment device; the feed roller bracket was remade; the feed roller bearings, drive sprockets, chains, etc. were reused from old parts of the original Jingzhen Sugar Factory.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
