Description

Technical Field

[0001] This utility model relates to the field of konjac processing technology, and in particular to a multi-stage grinding device for konjac processing. Background Technology

[0002] The underground tuber of konjac is flattened-spherical, large, with a stout, cylindrical, light green petiole with dark purple spots. It has palmate compound leaves with a white interior. When processing konjac into food, it is primarily ground into powder first, and then further processed into food products.

[0003] An existing multi-stage grinding device for konjac processing, with publication number CN 222446650 U, involves feeding konjac onto a conveyor plate. A sealing plate blocks the konjac on the conveyor plate, and two electric push rods extend to lower a grid-like dividing plate on the conveyor plate. The descending grid-like dividing plate cuts the konjac into uniformly sized small pieces. The electric push rods then retract, causing the grid-like dividing plate to rise. At this point, several push rods enter the dividing holes on the grid-like dividing plate to push out the cut konjac. When the grid-like dividing plate and the conveyor plate are at their maximum distance, a positioning sleeve connects to allow the sealing plate to rise and release the blockage on the left side of the conveyor plate. The small pieces of konjac slide down the conveyor plate through the inlet to the grinding chamber. The drive assembly drives two large-tooth grinding rollers for initial grinding, followed by two small-tooth grinding rollers for secondary fine grinding, before sliding out through the outlet. However, this device requires pre-grinding of the konjac, adding a processing step and causing inconvenience. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage grinding device for konjac processing in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A multi-stage grinding device for konjac processing includes a support mechanism. The support mechanism includes a base frame, a support bracket fixed to the upper end of the base frame, and a processing cylinder mounted vertically on the support bracket. The upper end of the processing cylinder is open and equipped with a feeding hopper. A discharge port is provided on the lower part of the outer wall of the processing cylinder. The support mechanism is equipped with a grinding mechanism for feeding, rotary cutting, and grinding konjac sequentially from top to bottom. The grinding mechanism includes a rotating shaft vertically passing through the center of the processing cylinder. A grinding assembly is fixed on the outer diameter of the rotating shaft inside the processing cylinder. The grinding assembly includes a fine grinding roller fixed to the lower part of the rotating shaft. A coarse grinding roller is fixed to the upper end of the fine grinding roller. A rotary cutter is provided on the upper side of the coarse grinding roller on the outer wall of the rotating shaft. A spiral feeding blade is provided on the upper side of the rotary cutter. A power assembly is connected to the lower end of the rotating shaft.

[0007] Further configuration: The coarse grinding roller is conical in shape and has raised ribs evenly distributed around its outer wall. The inner wall of the processing cylinder is provided with raised strips that are opposite to the raised ribs.

[0008] Further configuration: The rotary cutting blades are evenly distributed and fixed on the outer diameter of the rotating shaft, and the rotary cutting blades are configured in at least two layers.

[0009] Further configuration: The spiral feed blades are welded to the rotating shaft, and the spiral feed blades are tangent to the inner wall of the processing cylinder.

[0010] Further configuration: The rotating shaft is rotatably connected to the bottom frame and the processing cylinder. The bottom of the inner wall of the processing cylinder is set as an inclined surface towards the discharge port.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By setting up a grinding mechanism, the power unit drives the grinding component to rotate. During the rotation of the grinding component's shaft, the konjac in the feeding hopper is gradually fed downwards to the rotary cutter through the rotating spiral feed blades. The rotating rotary cutter cuts the konjac, which then moves downwards to the coarse grinding roller. The rotating coarse grinding roller and the inner wall of the processing cylinder perform preliminary grinding on the rotary-cut konjac. Then, it moves downwards to the fine grinding roller, where the rotating fine grinding roller and the inner wall of the processing cylinder perform further grinding on the coarsely ground konjac. Finally, it is discharged through the outlet. The entire feeding and grinding process is completed within the processing cylinder, simplifying the processing steps and improving processing efficiency. Attached Figure Description

[0024] like Figures 1-4 As shown, a multi-stage grinding device for konjac processing includes a support mechanism, on which a grinding mechanism is provided for feeding, rotary cutting and grinding konjac sequentially from top to bottom.

[0025] In this embodiment: the support mechanism includes a base frame 11, a support frame 12 is fixed at the upper end of the base frame 11, and a processing cylinder 13 installed on the base frame 11 is vertically fixed on the support frame 12.

A guide hopper 16 is provided on the outer wall of the processing cylinder 13 at the discharge port 15 to facilitate the guiding and outflow of the ground konjac.

[0026] In this embodiment: the grinding mechanism includes a rotating shaft 21 that is vertically inserted through the center of the processing cylinder 13. A grinding assembly is fixed on the outer diameter of the rotating shaft 21 inside the processing cylinder 13. The grinding assembly includes a fine grinding roller 22 fixed on the lower part of the rotating shaft 21. A coarse grinding roller 23 is fixed on the upper end of the fine grinding roller 22. A rotary cutter 24 is provided on the upper side of the coarse grinding roller 23 on the outer wall of the rotating shaft 21. A spiral feed blade 25 is provided on the upper side of the rotary cutter 24. A power assembly is connected to the lower end of the rotating shaft 21.

[0027] The coarse grinding roller 23 is conical in shape and has raised ribs evenly distributed around its outer wall. The inner wall of the processing cylinder 13 has raised strips opposite to these ribs. The rotary cutter 24 is evenly distributed around the outer diameter of the rotating shaft 21 and has at least two layers. The spiral feed blade 25 is welded to the rotating shaft 21 and is tangential to the inner wall of the processing cylinder 13. The rotating shaft 21 is rotatably connected to the bottom frame 11 and the processing cylinder 13. During the rotation of the rotating shaft 21… The konjac in the feeding hopper 14 is fed downwards through the rotating spiral feed blades 25 to the rotary cutter 24. The rotating rotary cutter 24 cuts the konjac, which then moves downwards to the coarse grinding roller 23. The rotating coarse grinding roller 23 and the inner wall of the processing cylinder 13 perform preliminary grinding on the rotary cut konjac. Then it moves downwards to the fine grinding roller 22.

The motor 27 drives the drive member 28 to rotate, and the power is transmitted through the transmission belt to drive the secondary drive member 26 and the rotating shaft 21 to rotate as a whole.

[0029] The working principle and usage process of this utility model are as follows: The motor 27 drives the active component 28 to rotate, which in turn drives the auxiliary component 26 and the rotating shaft 21 to rotate via the transmission component. The fine grinding roller 22, coarse grinding roller 23, rotary cutter 24 and spiral feed blade 25 on the rotating shaft 21 rotate as a whole, adding konjac into the feeding hopper 14. The spiral feed blade 25 feeds the konjac downwards to the rotary cutter 24, where the rotating rotary cutter 24 cuts the konjac. Then, the konjac moves downwards to the coarse grinding roller 23, where the rotating coarse grinding roller 23 and the inner wall of the processing cylinder 13 perform preliminary grinding on the cut konjac. Then, the konjac moves downwards to the fine grinding roller 22, where the rotating fine grinding roller 22 and the inner wall of the processing cylinder 13 perform further grinding on the coarsely ground konjac. Finally, the konjac is discharged through the discharge port 15.
