[0001] This utility model relates to the technical field of bamboo product processing equipment, specifically a sharpening tool for bamboo chopsticks. Background Technology
[0002] In the bamboo chopstick manufacturing industry, the sharpening process is a crucial step. With the development of mechanical automation technology, bamboo chopstick sharpening tools have emerged. These tools use mechanical drives to achieve rapid and precise sharpening of bamboo chopsticks, greatly improving production efficiency and product quality.
[0003] However, during the cutting process, the bamboo chopsticks often shift due to uneven force, which seriously affects the accuracy and efficiency of sharpening. At the same time, the tip of the traditional tool is subjected to great stress concentration, and chipping occurs frequently. Frequent tool replacements will also interrupt production continuity, further reducing production efficiency. Utility Model Content
[0004] To address the shortcomings of existing technologies, such as the displacement of bamboo chopsticks due to uneven force, which seriously affects the accuracy and efficiency of sharpening, frequent chipping, and the need for frequent tool replacements that disrupt production continuity and further reduce production efficiency, this utility model provides a sharpening tool for bamboo chopsticks.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] This utility model discloses a sharpening tool for bamboo chopsticks, including a blade disc. The outer wall of the blade disc is provided with L-shaped mounting seats evenly distributed in a ring around it. Each L-shaped mounting seat away from the blade disc is fixedly mounted with a chamfered cutting blade for cutting. The chamfered cutting blade is fixedly mounted to the L-shaped mounting seat by a mounting structure.
[0007] The upturned cutting tool includes a blade, and a straight cutting edge and an upturned tip are provided on one side of the outer wall of the blade. The included angle between the straight cutting edge and the upturned tip is 178°.
[0008] As a preferred embodiment of this utility model, a connecting hole for connecting the cutter head to the drive shaft is provided at the center of the cutter head.
[0009] As a preferred technical solution of this utility model, the mounting structure includes a mounting groove opened at the end of the L-shaped mounting base away from the cutter head, and the mounting groove is adapted to the cutter body, and openings are provided on both sides of the outer wall of the cutter head.
[0010] As a preferred technical solution of this utility model, the outer side wall of the L-shaped mounting base is provided with threaded holes that are adapted to the opening on both sides of the mounting groove near the opening.
[0011] As a preferred embodiment of this utility model, both the straight blade and the upturned tip are made of diamond.
[0012] As a preferred technical solution of this utility model, the outer side wall of the blade is provided with countersunk holes around the opening on the side away from the threaded hole.
[0013] The beneficial effects of this utility model are:
[0014] 1. This type of bamboo chopstick sharpening tool, through the cooperation of the blade disc, L-shaped mounting base, and curved cutting blade, generates greater friction when the curved blade tip contacts the bamboo chopstick due to the 178° angle between the curved blade tip and the blade body. This helps to fix the bamboo chopstick in the cutting position and improves the stability of the bamboo chopstick during the cutting process. At the same time, due to the tilt angle, the cutting force can be more evenly distributed between the curved blade tip and the straight blade, which helps to reduce the concentrated stress on the blade tip during the cutting process. This can minimize the risk of chipping during the cutting process and help improve the processing accuracy and production efficiency of the product.
[0015] 2. This type of bamboo chopstick sharpening tool, through the cooperation of the mounting groove, opening and threaded hole, allows the bolt to be removed from the threaded hole when one of the chopsticks is damaged. Then the damaged chopstick can be removed from the L-shaped mounting base and replaced with a new chopstick. This allows for individual replacement of damaged chopsticks, avoiding the need to replace the entire tool after a single tool tip is damaged or severely worn, thus minimizing tool maintenance costs.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0023] Reference Figure 1 and Figure 2 This utility model discloses a sharpening tool for bamboo chopsticks, including a blade disc 1. A connecting hole 4 is provided at the center of the blade disc 1 for connecting it to a drive shaft. In use, the blade disc 1 is installed on the drive shaft through the connecting hole 4. L-shaped mounting seats 2 are evenly distributed in a ring around the outer wall of the blade disc 1. A chamfered cutting blade 3 is fixedly installed at the end of each L-shaped mounting seat 2 away from the blade disc 1. The chamfered cutting blade 3 is fixedly installed on the L-shaped mounting seat 2 by a mounting structure. When it is necessary to cut the bamboo chopsticks, the drive shaft drives the blade disc 1 along... Figure 2 Rotating in direction A, which in turn drives the L-shaped mounting base 2 and the chamfered cutting tool 3 fixedly mounted on the L-shaped mounting base 2 along... Figure 2 As the chopsticks rotate in direction A, the upward-pointing cutting blade 3 sharpens them as it passes by.
[0024] Reference Figure 1 , Figure 2 and Figure 3 The curved cutting blade 3 includes a blade body 31. A straight blade 32 and a curved tip 33 are provided on one side of the outer wall of the blade body 31. The included angle between the straight blade 32 and the curved tip 33 is 178°. Since there is a 2° tilt angle between the curved tip 33 and the blade body 31, a greater friction force can be generated when the curved tip 33 contacts the bamboo chopsticks, which helps to fix the bamboo chopsticks in the cutting position and improves the stability of the bamboo chopsticks during the cutting process.
[0025] Meanwhile, due to the tilt angle, the cutting force can be more evenly distributed between the curved tip 33 and the straight cutting edge 32, which helps to reduce the concentrated stress on the tip during cutting and thus minimizes the risk of chipping. Both the straight cutting edge 32 and the curved tip 33 are made of diamond. Due to the extremely high hardness and wear resistance of diamond, the diamond straight cutting edge 32 and the curved tip 33 can still maintain a sharp cutting edge after long-term use, which helps to reduce cutting instability and bamboo chopstick slippage caused by tool wear.
[0026] Reference Figure 2 , Figure 3 and Figure 4 The installation structure includes a mounting groove 5 at the end of the L-shaped mounting base 2 away from the cutter head 1, and the mounting groove 5 is adapted to the blade body 31. Openings 6 are provided on both sides of the outer wall of the blade body 31. Threaded holes 7 that are adapted to the openings 6 are provided on both sides of the outer wall of the L-shaped mounting base 2 near the openings 6 in the mounting groove 5. Countersunk holes 8 are provided on one side of the outer wall of the cutter head 1 around the openings 6. When it is necessary to fix the curved cutting blade 3 to the cutter head 1, the blade body 31 is first placed in the mounting groove 5, and then the bolt is threaded through the openings 6 and connected to the threaded holes 7. At the same time, the end of the bolt away from the threaded holes 7 is sunk into the countersunk holes 8 to ensure the flatness of the outer wall of the blade body 31 as much as possible, and to avoid the bottom of the bolt being lower than the height of the blade body 31, the straight blade 32 and the curved blade tip 33, which would affect the sharpening of the bamboo chopsticks.
[0027] The working principle of this utility model is as follows:
[0028] During operation, the blade 31 is first placed in the mounting slot 5, and then the bolt is threaded through the opening 6 and connected to the threaded hole 7, thereby fixing the chamfered cutting blade 3 to the L-shaped mounting base 2 and the blade disc 1. After all the chamfered cutting blades 3 are installed, the blade disc 1 is installed on the drive shaft through the coupling hole 4.
[0029] When it is necessary to cut the bamboo chopsticks, the drive shaft drives the cutter head 1 along... Figure 2 Rotating in direction A, which in turn drives the L-shaped mounting base 2 and the chamfered cutting tool 3 fixedly mounted on the L-shaped mounting base 2 along... Figure 2 When the blade rotates in direction A, the pointed cutting blade 3 sharpens the bamboo chopsticks as it passes by.
[0030] Because there is a 2° tilt angle between the tip 33 and the blade 31, the tip 33 can generate greater friction when it contacts the bamboo chopsticks. This helps to fix the bamboo chopsticks in the cutting position and improves their stability during the cutting process. At the same time, the tilt angle allows the cutting force to be distributed more evenly between the tip 33 and the blade 31, which helps to reduce the concentrated stress on the tip during the cutting process and thus minimizes the risk of chipping.
[0031] When one of the jacking cutters 3 is damaged, the bolt can be removed from the internal thread of the threaded hole 7, and then the damaged jacking cutter 3 can be removed from the L-shaped mounting base 2. A new jacking cutter 3 can be replaced, and then the new jacking cutter 3 can be re-fixed to the L-shaped mounting base 2 with bolts.
[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
