Description

Technical Field

[0001] This utility model relates to the technical field of bamboo processing equipment, and more specifically, to a bamboo chopsticks lengthening and sharpening knife. Background Technology

[0002] Bamboo chopsticks are made from bamboo, a natural and renewable resource with advantages such as fast growth and environmental friendliness. Using bamboo chopsticks can reduce environmental pollution and aligns with modern people's pursuit of a green lifestyle.

[0003] Due to manufacturing issues, the mounting surface of existing bamboo chopstick sharpening blades is not perfectly flat. If a material with high hardness and low toughness is used to make the sharpening blade, it is easy to break at the blade fixing groove when the sharpening blade is locked. Therefore, at present, only materials with relatively high toughness and relatively low hardness can be used to make the sharpening blade, which ultimately makes the sharpening blade very undurable.

[0004] A search revealed that Chinese patent CN205799778U discloses a sharpening tip for bamboo chopsticks, which can fix the sharpening blade without creating a fixing groove, thereby improving the strength of the sharpening blade itself. This allows the use of materials with high hardness and low toughness to make the sharpening blade, greatly extending its service life.

[0005] In actual use, the aforementioned bamboo chopstick sharpening blades are currently being produced because the bamboo chopsticks are subjected to high force, making them prone to slipping and damaging the blade tip. The process of replacing the blade is cumbersome for operators, resulting in excessive time spent on this task and impacting production progress. Utility Model Content

[0009] The disassembly assembly includes a pull rod mounted on the outside of a first tool holder. A connecting rod is fixedly connected to the bottom end of the pull rod, and a first sliding block is fixedly connected to the bottom end of the connecting rod. Two first sliding rods are fixedly connected to the outside of the first sliding block. Two guide plates are installed inside the first tool holder. A second sliding block is slidably connected to the inside of the guide plates. A second sliding groove is formed on one side of the second sliding block. A fixing plate is fixedly connected to the bottom end of the second sliding block, and a connecting plate is fixedly connected to one side of the second sliding block. A spring is fixedly connected to one side of the connecting plate. A second tool holder is fixedly connected to the rear of the first tool holder. Multiple extended blades are fixedly connected to the outside of the second tool holder. The first sliding rods are slidably connected to the inside of the second sliding groove. The springs are symmetrically distributed on the outside of the second sliding block.

[0010] By adopting the above technical solution, the second sliding block drives the locking rod to move, which facilitates the separation and locking of the locking rod from the inside of the locking groove, thereby making it easier for operators to disassemble and replace the blade.

[0011] As a further description of the above technical solution: two locking rods are fixedly connected to one side of the fixing plate, a second sliding rod is slidably connected to the inner side of the first sliding groove, a blade is fixedly connected to the bottom end of the second sliding rod, and multiple locking slots are opened on the outer side of the second sliding rod. The locking slots are symmetrically distributed on the outer side of the second sliding rod, and the locking rod engages with the inner side of the locking slot.

[0012] By adopting the above technical solution: the blade facilitates the sharpening of the extended bamboo chopsticks, and the clamping rod can limit and fix the second slide rod inside the first tool holder.

[0013] As a further description of the above technical solution: a protective mechanism is installed on the outside of the first tool holder, the protective mechanism including a tool disc, the tool disc being fixedly connected to the inside of the first tool holder, and connecting grooves being opened on the surfaces of both the tool disc and the second tool holder, the connecting grooves being symmetrically distributed on the outside of the tool disc, a protective shell is installed on the outside of the first tool holder, and two connecting slip rings are fixedly connected to the inside of the protective shell, the connecting slip rings being slidably connected to the inside of the connecting grooves, the first sliding rod being slidably connected to the inside of the second sliding groove, and the springs being symmetrically distributed on the outside of the second sliding block.

[0014] By adopting the above technical solution, the first tool holder rotates inside the protective shell, so that the protective shell can provide protection outside the first tool holder.

[0015] As a further description of the above technical solution: the first and second tool holders are fixedly connected to the output end of the drive device of the bamboo chopstick sharpening machine, so as to drive the two sets of tool holders through the bamboo chopstick sharpening machine. One side of the protective shell is fixedly connected to the bamboo chopstick sharpening machine through two sets of connecting lugs for fixing the protective shell.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. By setting up a disassembly component, compared with the existing technology, the second sliding block can drive the locking rod to move inside the first tool holder, which makes it easy for operators to quickly disassemble and replace the blade, thereby saving the time and effort required to replace the blade, improving work efficiency, and making it easier to clean and inspect the blade, thus extending the service life of the sharpening tool.

[0018] 2. By setting up a protective mechanism, compared with the existing technology, the connecting slip ring is used to slide the connection inside the connecting groove, which makes it easy for the first tool holder to rotate inside the protective shell. This can effectively prevent scratches or cuts caused by accidental contact during use or storage, prevent accidental injuries, and at the same time make the first tool holder more stable during use, thus enhancing the stability of the first tool holder.

The locking rod 11 is engaged with the inside of the slot 15. By pulling the pull rod 3, the pull rod 3 drives the first sliding block 5 to move upward through the connecting rod 4. The first slide rod 6 is slidably connected to the inside of the second slide groove 8. At the same time, the cut surface on the outside of the first sliding block 5 is in contact with one side of the second sliding block 7, so that the first sliding block 5 can push the two second sliding blocks 7 to move outward. The second sliding block 7 can drive the two locking rods 11 to separate from the inside of the slot 15 through the fixing plate 10, so as to facilitate the disassembly of the blade 14. While the second sliding block 7 is moving, the connecting plate 12 can pull the spring 13 to extend. When the blade 14 is replaced, the pull rod 3 is released. The return force of the spring 13 can pull the two second sliding blocks 7 to move relative to each other, so that the two second sliding blocks 7 can drive the locking rod 11 to be inserted into the slot 15. This allows the operator to quickly disassemble and replace the blade 14, thus saving the time and effort required to replace the blade.

[0031] Reference Figure 1 As shown, a protective mechanism is installed on the outside of the first tool holder 1. The protective mechanism includes a cutter disc 20, which is fixedly connected to the inside of the first tool holder 1. Both the cutter disc 20 and the second tool holder 21 have connecting grooves 17 on their surfaces, which are symmetrically distributed on the outside of the cutter disc 20. A protective shell 18 is installed on the outside of the first tool holder 1. Two connecting slip rings 19 are fixedly connected to the inside of the protective shell 18, and the connecting slip rings 19 are slidably connected to the inside of the connecting grooves 17. The first sliding rod 6 is slidably connected to the inside of the second sliding groove 8. Springs 13 are symmetrically distributed on the outside of the second sliding block 7. The first tool holder 1 and the second tool holder 21 are fixedly connected to the drive mechanism of the bamboo chopstick sharpening machine. The output end is used to drive the two sets of tool holders through the bamboo chopstick sharpening machine. One side of the protective shell 18 is fixedly connected to the bamboo chopstick sharpening machine through two sets of connecting lugs to fix the protective shell 18. The connecting slip ring 19 is rotatably connected to the inner side of the connecting groove 17, so that the first tool holder 1 can rotate inside the protective shell 18. This allows the protective shell 18 to protect the first tool holder 1 from the outside, effectively preventing scratches or cuts caused by accidental contact during use or storage, thereby reducing the risk of use. At the same time, it makes the rotation of the first tool holder 1 more stable during use, thereby improving the processing quality.

[0032] Working principle of this utility model: This utility model designs an extended and sharpened bamboo chopstick sharpener, the specific structure of which is shown in the attached instruction manual. Figure 1-6As shown, in this technical solution, through the cooperation between various structures, when the damaged blade 14 needs to be replaced, firstly, the pull rod 3 is pulled. The pull rod 3 drives the first sliding block 5 to move upward through the connecting rod 4, so that the first sliding block 5 can drive the two first sliding rods 6 to slide and connect inside the second sliding groove 8. Through the fit between the slope on the outside of the first sliding block 5 and the slope on one side of the second sliding block 7, the upward movement of the first sliding block 5 can push the two second sliding blocks 7 to move to both sides. The second sliding blocks 7 and the guide plate are used to... The inner sliding connection of the guide plate 9 provides guidance for the movement of the second sliding block 7, facilitating the separation of the second sliding block 7 from the inner side of the slot 15 via the fixing plate 10 and the locking rod 11. Simultaneously, the two second sliding blocks 7 extend to both sides via the connecting plate 12 pulling the spring 13. Then, the damaged blade 14 is pulled out, and the second sliding rod 16 at the tip of the replacement blade 14 is inserted into the first sliding groove 2. One end of the second sliding rod 16 is pressed against the deep inner side of the first sliding groove 2. Then, the pull rod 3 is released, and the restoring force of the two springs 13 can be used to pull... The two second sliding blocks 7 move relative to each other, which facilitates the insertion of multiple locking rods 11 into the locking slots 15. The second sliding rod 16 can be limited, thus completing the replacement of the blade 14. When the first knife holder 1 is needed to sharpen the bamboo chopsticks, the drive device is fixed to the blade disc 20 and drives the blade disc 20 to rotate. This allows the first sliding groove 2 to drive the multiple blades 14 and the extended blades 22 on one side of the first knife holder 1 and the second knife holder 21 to stably sharpen the conical surface of the extended bamboo chopsticks. At the same time, the connecting sliding ring 19 is rotatably connected to the inner side of the connecting groove 17. The protective shell 18 is fixedly connected to the bamboo chopstick sharpening machine through two sets of connecting lugs on one side, which is used to fix the protective shell 18. This allows the first knife holder 1 and the second knife holder 21 to rotate inside the protective shell 18, so that the protective shell 18 can protect the outside of the first knife holder 1 and the second knife holder 21. At the same time, the multiple extended blades 22 are openly distributed on the outside of the second knife holder 21, which is conducive to chip removal and heat dissipation, and works with the protective shell 18 to avoid accidents caused by flying knives.
