Description

Technical Field

[0001] This invention relates to the field of bamboo chopsticks processing, and more particularly to a sharpening device for bamboo chopsticks processing. Background Technology

[0002] Chopsticks are an indispensable utensil in daily life. They are long and thin sticks, and most chopsticks commonly seen are made of bamboo or wood. The process of making chopsticks from bamboo and wood involves first processing the bamboo or wood into boards, then cutting the boards into strips, then cutting the strips into short strips of uniform length, and finally polishing the short strips. The polished product is a semi-finished bamboo chopstick, which is then sharpened and rounded to become the finished bamboo chopstick.

[0003] Bamboo chopsticks are sharpened using a sharpening device. Patent application number CN202022214968.8 discloses a raw material sharpening machine for bamboo chopstick production and processing, which includes a worktable, a first mounting frame, a second mounting frame, a fixing plate, a brake motor, and a stepper motor. A fixing seat is installed at the top of the worktable, and a groove is opened at the top of the fixing seat. A first slider is arranged inside the groove, and a first mounting frame is installed at the top of the first slider. A first threaded rod is installed inside the first mounting frame through a bearing, and a mounting seat is provided on the outer wall of the first threaded rod. A second mounting frame is installed at the top of the mounting seat, and fixing plates are installed at both ends of the top of the second mounting frame. When using the device, the raw material is first placed on the top of the second mounting frame. Then, the operator rotates the turntable, which drives the second threaded rod to rotate. The second threaded rod is connected to the second threaded hole by a thread. While the second threaded rod rotates, it moves back and forth inside the second threaded hole. This movement of the second threaded rod drives the extrusion plate to clamp and fix the raw material. After the material is fixed, it is sharpened by a cutting blade. However, this type of sharpening device requires workers to fix the material before sharpening. After sharpening, the product needs to be removed and fixed again, resulting in low production efficiency of bamboo chopsticks.

[0004] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sharpening device for processing bamboo chopsticks.

[0006] This invention can be achieved through the following technical solutions: This invention discloses a sharpening device for processing bamboo chopsticks, comprising a frame, a feeding hopper fixed on the frame, a distributing motor fixed on the frame at the end of the feeding hopper, a rotating shaft fixed at the output end of the distributing motor, multiple distributing plates fixed on the rotating shaft, distributing grooves evenly arranged on the distributing plates, multiple sliding rods fixed on the frame on one side of the distributing plates, a sliding plate above the sliding rods, sliding tubes fixed on the sliding plate at positions corresponding to the sliding rods, the sliding rods passing through the sliding tubes and slidably connected to the sliding tubes, the sliding plate being driven to move by a positioning motor, a sharpening shaft also being provided on the sliding plate, a fixing plate fixed on the sharpening shaft, multiple fixing seats evenly fixed on the fixing plate, each fixing seat having a blade fixed on it, a grinding shaft also being provided on the sliding plate, multiple conical grinding rollers fixed on the grinding shaft, the grinding shaft and the sharpening shaft being driven to rotate by a sharpening motor.

[0010] Preferably, a receiving hopper is also fixed on the frame on one side of the distributing plate, and a baffle plate is also fixed on the receiving hopper. The baffle plate is arranged between adjacent distributing plates. When the polished bamboo chopsticks rotate with the distributing plate, they come into contact with the baffle plate. Due to the baffle plate's obstruction, the bamboo chopsticks separate from the distributing trough and slide into the receiving hopper for collection.

[0011] Preferably, the bottom of the hopper is provided with an opening penetrating the hopper, and a slider is provided on one side of the opening. Multiple support rods are fixed to the slider, and the support rods pass through the frame and are slidably connected to it.

[0014] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings: Example

[0015] like Figures 1 to 5As shown, this embodiment discloses a sharpening device for processing bamboo chopsticks, comprising a frame 1, a feeding hopper 2 fixed on the frame 1, a distributing motor 3 fixed on the frame 1 at the end of the feeding hopper 2, a rotating shaft 4 fixed on the output end of the distributing motor 3, multiple distributing plates 5 fixed on the rotating shaft 4, distributing grooves 6 evenly arranged on the distributing plates 5, and multiple sliding rods 7 fixed on the frame 1 on one side of the distributing plates 5, and a sliding plate 8 above the sliding rods 7, with corresponding positions on the sliding plate 8 fixed to the sliding rods 7. The slide has a slide tube, and the slide rod 7 passes through the slide tube and is slidably connected to the slide tube. The slide plate 8 is driven to move by the positioning motor 9. The slide plate 8 is also equipped with a sharpening shaft 16, and a fixing plate 17 is fixed on the sharpening shaft 16. Multiple fixing seats 18 are evenly fixed on the fixing plate 17, and blades 19 are fixed on each fixing seat 18. The slide plate 8 is also equipped with a grinding shaft 20, and multiple conical grinding rollers 22 are fixed on the grinding shaft 20. Both the grinding shaft 20 and the sharpening shaft 16 are driven to rotate by the sharpening motor 14. The bamboo chopsticks to be sharpened are piled in the feeding hopper 2. The bottom chopsticks slide to the distribution plate 5, and the outermost chopsticks enter the distribution groove 6 of the distribution plate 5. The distribution motor 3 drives the rotating shaft 4 to rotate at a certain angle, and the chopsticks re-enter the distribution groove 6. After the chopsticks rotate with the distribution plate 5 to the designated position, the sharpening motor 14 drives the sharpening shaft 16 and the grinding shaft 20 to rotate. The blade 19 rotates around the chopsticks. The positioning motor 9 drives the slide plate 8 to move, and the blade 19 moves with the slide plate 8. After the high-speed rotating blade 19 contacts the chopsticks, it rotates around them. Since the blade 19 is tilted and fixed, it sharpens the chopsticks as it moves. After one end of the chopsticks is sharpened, the positioning motor 9 drives the slide plate 8 back to the initial position, and then the distribution motor 3 drives the rotating shaft 4 again. After rotating a certain angle, the next bamboo chopstick to be sharpened reaches the position of the blade 19, and the sharpened bamboo chopstick reaches the position of the grinding roller 22. The positioning motor 9 drives the slide plate 8 to move again, and the bamboo chopstick is sharpened again. The sharpened bamboo chopstick contacts the grinding roller 22. Since the grinding roller 22 rotates around the bamboo chopstick and the grinding roller 22 has a conical structure, it contacts the bamboo chopstick when rotating around it, and grinds the sharpened part of the bamboo chopstick. After the bamboo chopstick is ground smooth, the slide plate 8 returns to the initial position, and the rotating shaft 4 rotates again at a certain angle. The cycle continues, and the ground bamboo chopsticks are collected. This device can sharpen bamboo chopsticks, grind the sharpened bamboo chopsticks, and sharpen and grind bamboo chopsticks one by one, which greatly improves the production efficiency of bamboo chopsticks.

[0016] An arc-shaped baffle 23 is fixed on the frame 1 above the material distribution plate 5. The baffle 23 prevents the bamboo chopsticks from separating from the material distribution trough 6 during sharpening and polishing.

[0017] The slide plate 8 is fixed with a positioning rod 13, and the output end of the positioning motor 9 is fixed with a positioning disk 10. The positioning disk 10 is fixed with a positioning shaft 11, and the positioning shaft 11 is connected to the positioning rod 13 through a positioning push rod 12. The positioning motor drives the positioning disk to rotate, and when the positioning disk rotates, the positioning push rod pushes the slide plate to move back and forth.

[0018] Among them, the output end of the sharpening motor 14 is fixed with a main gear 15, and both the grinding shaft 20 and the sharpening shaft 16 are fixed with driven gears 21, and both driven gears 21 mesh with the main gear 15.

[0019] A receiving hopper 24 is fixed on the frame 1 on one side of the distributing plate 5, and a baffle plate 25 is fixed on the receiving hopper 24. The baffle plate 25 is set between adjacent distributing plates 5. When the polished bamboo chopsticks rotate with the distributing plate 5, they come into contact with the baffle plate 25. After being blocked by the baffle plate 25, the bamboo chopsticks separate from the distributing trough 6 and slide into the receiving hopper 24 for collection. Example

[0020] This embodiment discloses a sharpening device for processing bamboo chopsticks. Based on the structure and principle of embodiment 1, the bottom of the feeding hopper 2 in this embodiment is also provided with an opening 26 that penetrates the feeding hopper 2. A slider 31 is also provided on one side of the opening 26. Multiple support rods 32 are fixed on the slider 31. The support rods 32 pass through the frame 1 and are slidably connected to the frame 1. A shaking plate 34 is also fixed on the slider 31. A protrusion 35 is evenly fixed on the upper end of the shaking plate 34. A limit rod 33 is also fixed on the slider 31. A shaking motor 27 is also fixed on the frame 1. A turntable 28 is fixed at the output end of the shaking motor 27. A limit shaft 29 is also fixed on the turntable 28. The limit shaft 29 is connected to the limit rod 33 through a limit push rod 30. Bamboo chopsticks are piled up in the feeding hopper 2. The rotating disk 28 is driven to rotate by the shaking motor 27. When the rotating disk 28 rotates, the slider 31 moves back and forth, the shaking plate 34 moves back and forth, and the protrusion 35 moves with the shaking plate 34, causing the bamboo chopsticks to vibrate, thus preventing the bamboo chopsticks from piling up and pushing them into the distributing trough 6.

[0021] The above are merely preferred embodiments of the present invention. It should be noted that, for those skilled in the art, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the technical principles of the present invention. These changes, modifications, substitutions and variations should also be considered within the scope of protection of the present invention.
