Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to a segment cutter roller and a segment cutter. Background Art

[0002] Dried chili peppers usually need to be cut into segments before packaging and transportation. The existing dried chili pepper segmentation machines on the market use a cutting roller and a rubber roller to squeeze and cut the chili peppers. The principle is that the cutting roller is installed above the rubber roller, and the blade on the surface of the cutting roller contacts the rubber roller. During the rotation of the cutting roller, the dried chili peppers are cut with the rubber roller as the bottom pad. Since chili residues are easily accumulated on the cutting roller during the cutting process, it is necessary to design a segmentation machine roller knife that can avoid residue accumulation, has a simple structure, and is easy to install.

[0021] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] Example 1

[0023] See also Figures 1 to 3 The present embodiment provides a segment cutting machine roller cutter, comprising a roller shaft 1, a roller disc 2 and a blade 3. The roller disc 2 is a circular ring with supporting ribs. There are more than two roller discs 2. The roller shaft 1 passes through the center of each roller disc 2 and is fixed to the roller disc 2. The roller disc 2 is provided with a knife-through groove 21 distributed around the circumference. The blade 3 is a long strip and is installed in the knife-through groove 21. The blade 3 is provided at the back of the blade 32 corresponding to the position of the roller disc 2, and the L-shaped hook 31 is extended away from the blade toward the center of the roller disc 2. The L-shaped hook 31 hooks the inner circle of the roller disc 2.

[0024] Furthermore, the roller cutter is also provided with a fixed blade disc 4, which is in the shape of a disc. The roller shaft 1 passes through the center of the fixed blade disc 4. The fixed blade disc 4 is arranged on the outer side of the outermost roller disc on the same side as the L-shaped hook 31. The fixed blade disc 4 is tightly attached to the end of the blade 3 or the L-shaped hook 31 to press the blade 3.

[0025] Specifically, the fixed blade disc 4 is annular with a fixed blade rib 42, and a through hole 41 is provided in the center of the fixed blade rib 42, and the roller shaft 2 passes through the through hole 41 and is fixedly installed with the fixed blade disc 4. The through hole 41 is provided with a screw hole, and a screw passes through the screw hole to fix the fixed blade disc 4 on the roller shaft 1.

[0026] A through hole 25 is provided in the center of the support rib 23, and the roller shaft 2 passes through the through hole 25 and is fixedly installed with the roller disc 2. The height of the L-shaped hook 31 matches the width of the roller disc ring. A hanging hole 24 is provided on the support rib 23, and the L-shaped hook 31 hooks the hanging hole 24.

[0027] Among the multiple roller discs 2, a plurality of knife-piercing grooves 21 of the same size are evenly distributed on the outer circumference of each roller disc 2. A positioning groove 26 is provided on each roller disc 2, and the positioning groove 26 is used to correspond to the protrusion (not shown in the figure) on the clamping roller shaft 1 to ensure that the roller disc 2 can be fixedly installed on the roller shaft 1. In other embodiments, screw holes can also be provided on the positioning ring 25 to fix the roller disc 2 on the roller shaft 1 by screws, but the utility model is not limited to this.

[0028] The installation method of the roller cutter of the segment cutter provided in this embodiment is as follows: first, align the positioning groove 26 of the roller disc 2 with the corresponding clamping position on the roller shaft, that is, clamp and fix the roller disc 2 on the roller shaft 1 according to the preset position on the roller shaft 1. Then, clamp the blade back 32 of the blade 3 in the blade penetration groove 21 of multiple roller discs 2, and then push the blade 3 until the L-shaped hook 31 hooks the inner circle of the roller disc 2. Repeat the operation, and after all the blades 3 are installed on the roller disc 2, install the fixed blade disc 4 on the outer side of the outermost roller disc 2 on the same side as the L-shaped hook 31, so that the fixed blade disc 4 is tightly attached to the end of the blade 3 or the L-shaped hook 31, press the blade 3, and then fasten the fixed blade disc 4 to the roller shaft 2, and the installation of the segment cutter roller cutter is completed.

[0029] Example 2

[0030] Please refer to Figure 4 The utility model also provides a segmenting machine having the segmenting machine roller cutter of embodiment 1, the segmenting machine comprises a frame 5, a conveying device 6, a roller cutter 7 and a bottom roller 8, the conveying device 6, the roller cutter 7 and the bottom roller 8 are installed on the frame 5, the roller cutter 7 and the bottom roller 8 are installed at the discharge end of the conveying device 6, the bottom roller 8 is installed below the roller cutter 7, and when the roller cutter 7 rotates, the blade on the roller cutter 7 will contact the surface of the bottom roller 8.

[0031] Furthermore, the conveyor device 6 includes a motor, a conveyor belt, a baffle 9 and a conveyor wheel 10. The baffles 9 are arranged on both sides of the conveyor belt, and the conveyor wheel 10 is installed above the discharge end of the conveyor belt. The motor drives the conveyor belt, the conveyor wheel 10 and the roller cutter 7 to rotate respectively. The dried chilies to be processed are shaken off from the hopper 11 onto the conveyor belt and are conveyed forward by the conveyor belt.

[0032] A plurality of flexible paddles are installed on the transmission dial wheel 10, and the rotation direction of the transmission dial wheel 10 is the same as the feeding direction of the conveyor belt. The surface of the conveyor belt is provided with a plurality of parallel straight ridges along the conveying direction of the conveyor belt. The gap between two adjacent straight ridges is slightly larger than the width of the pepper. The end of the flexible paddle contacts the straight ridges. When the dry pepper falls onto the conveyor belt, part of the pepper falls into the gap between the straight ridges along the length direction of the pepper. The pepper is conveyed to the roller knife by the conveyor belt and cut into sections along the length direction of the pepper. Due to the direction of the other part of the pepper when it falls, it fails to fall into the gap between the straight ridges, but rests on the straight ridges. At this time, the flexible paddle pushes it down and falls into the gap between the straight ridges. At this time, the pepper moves forward along its length direction and is cut into sections along the length direction of the pepper by the roller knife.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as within the protection scope of the present invention.
