Description

Technical Field

[0001] This utility model relates to the field of chopsticks processing, specifically a chopsticks polishing and grinding machine. Background Technology

[0002] Polishing is a crucial step in the chopsticks production process, as it directly affects the chopsticks' appearance and feel.

[0003] Current manual or simple mechanical polishing methods are inefficient and cannot meet the needs of large-scale production due to the limited contact area between the polishing tools and chopsticks, and the difficulty in uniformly controlling the polishing force and speed. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a chopstick polishing and grinding machine.

[0005] The technical solution adopted by this utility model is as follows:

[0006] A chopstick polishing machine includes a support frame. Two support frames are symmetrically distributed left and right. The support frames are plate-shaped. A base plate is fixedly connected between the front and rear ends of the bottom of the two support frames. Support legs are fixedly connected to both ends of the bottom of the two base plates. Several support shafts pass through the middle of the support frames, and the support frames are rotatably connected to the several support shafts. The support shafts are equidistantly distributed. The foremost support shaft passes through the middle of a second connecting rod and is fixedly connected to the middle of the second connecting rod. Each of the remaining support shafts passes through the bottom of several first connecting rods and is fixedly connected to the bottom of a first connecting rod. A linkage rod is rotatably connected between the bottom of the opposite side walls of two second connecting rods. A fixing frame is located between the middle of the bottom of the two support frames. The middle part of the fixed frame is straight, and the left and right ends of the fixed frame extend upward.

[0018] like Figure 1-5The following describes a chopstick polishing machine: It includes a support frame 1, with two support frames 1 symmetrically distributed left and right. Each support frame 1 is plate-shaped. A base plate 2 is fixedly connected between the front and rear ends of the bottom of each of the two support frames 1. Support legs 3 are fixedly connected to both ends of the bottom of each of the two base plates 2. Several support shafts 6 pass through the middle of each support frame 1, and the support frames 1 are rotatably connected to the support shafts 6. The support shafts 6 are equidistantly distributed. The foremost support shaft 6 passes through the middle of a connecting rod 8 and is fixedly connected to the middle of the connecting rod 8. Each of the remaining support shafts 6 passes through the bottom of several connecting rods 7, and each support shaft 6 is fixedly connected to the bottom of a connecting rod 7. A linkage rod 9 is rotatably connected between the bottom of the opposite side walls of the two connecting rods 8. A fixing frame 10 is located between the middle of the bottom of the two support frames 1. The middle part is straight plate-shaped. The left and right ends of the fixing frame 10 extend upward. The top of the left and right ends of the fixing frame 10 are fixedly connected to the bottom of the two support frames 1 respectively. The left and right ends of the front side wall of the fixing frame 10 are fixedly connected to the fixing shaft 11. The bottom of the cylinder of the cylinder 12 is rotatably sleeved on the outer wall of the fixing shaft 11. The piston rod 13 of the cylinder 12 extends forward and upward. The front end of the piston rod 13 is fixedly connected to the middle of the outer wall of the linkage rod 9. There is a polishing box 15 between the tops of the two support frames 1. Several connecting shafts 14 are fixedly connected to the bottom of the polishing box 15. The connecting shafts 14 extend left and right and are equidistant from front to back. The left and right ends of the connecting shafts 14 pass through the top of the connecting rod 7 and the top of the connecting rod 8 on both sides respectively. The left and right ends of the connecting shafts 14 are rotatably connected to the top of the connecting rod 7 and the top of the connecting rod 8 on both sides respectively.

[0019] The lower part of the support leg 3 has a support block 20, and the lower part of the support leg 3 is fixedly connected to the support block 20. The spring 4 is located between the foot plate 5 and the support block 20, and the two ends of the spring 4 are fixedly connected to the bottom of the support block 20 and the top of the foot plate 5, respectively.

[0020] The top opening of the polishing box 15 is connected to the top right side of the polishing box 15 by a rotating box cover 16. The middle of the left side wall of the box cover 16 and the top of the middle of the left side wall of the polishing box 15 are both fixedly connected to the connecting plate 17. The locking bolt 18 passes through the upper connecting plate 17 and is threadedly connected to the lower connecting plate 17. The top middle of the box cover 16 is fixedly connected to the handle 19.

[0021] The chopsticks are placed in the polishing box 15, and a certain amount of polishing sand, which is diamond sand, is added into the polishing box 15. The polishing box 15 is connected to the connecting rod 7 and the connecting rod 8 through the connecting shaft 14. These connecting rods are connected to the support frame 1 through the support shaft 6. The cylinder 12 is in the initial position, and the piston rod 13 is not extended.

[0022] The lid 16 is fixed to the polishing box 15 by locking bolts 18 to ensure that the chopsticks will not fall out during the polishing process.

[0023] When cylinder 12 is started, piston rod 13 begins to extend rapidly forward and upward. The extension of piston rod 13 drives linkage rod 9 to move. Since linkage rod 9 is connected between two connecting rods 8, it will drive connecting rod 8, as well as the support shaft 6 and connecting rod 7 connected to it, to move together.

[0024] This motion is transmitted to the polishing box 15 through the connecting shaft 14, causing the polishing box 15 to shake and vibrate, which in turn drives the spring 4 to swing and vibrate, thus intensifying the shaking and vibration of the polishing box 15.

[0025] The chopsticks inside the polishing box 15 come into full contact with the polishing sand under the action of shaking or vibration, and are polished.

[0026] Once the predetermined polishing time is reached, cylinder 12 stops working, piston rod 13 retracts to its initial position, locking bolt 18 is unscrewed, cover 16 is opened, and polished chopsticks are taken out.

[0027] This utility model only protects the mechanical parts; the functions implemented by the software control part are not within the scope of protection of this utility model.
