Description

Technical Field

[0001] The invention relates to the field of bar polishing, in particular to a bar polishing machine. Background Art

[0002] Rods are long and thin sticks, mostly used as tableware. They are made of bamboo, wood, ivory, bone, metal, etc., and have different shapes, such as square or round. During the processing, burrs will appear on the surface, which needs to be polished and grinded to make the surface smooth. In the early days, workers did the polishing by hand on each rod, and the polishing effect was inconsistent and the efficiency was very low. In recent years, some mechanical equipment for automatic polishing of chopsticks has been launched on the market, such as the bamboo wood round bar screening and polishing method and its integrated production machine disclosed in CN 113926709 A. The bamboo wood round bars in the screening frame can be continuously rolled in an O shape by reciprocating the inferior product screen bracket. During the rolling process, the bamboo wood round bars rub against each other for polishing; during the rolling process, the bamboo wood round bars with both ends thinner than the qualified diameter fall from the screening groove on the side wall of the screening frame; during the rolling process, the bamboo wood round bars with the middle rod thinner than the qualified diameter fall into the screening groove on the first quality screen connected to the end of the inferior product screen bracket, and the breaking block connected to the side of the screening frame breaks the bamboo wood round bars in the screening groove. The broken bamboo wood round bars fall naturally and leave the screening groove, so that the screening of bamboo wood round bars with unqualified diameters at both ends and in the middle can be realized through a simple mechanical structure principle, and efficient and automatic screening of inferior bamboo wood round bars can be realized. However, the production process will be carried out in batches, and continuous flow production is impossible, which is not conducive to improving production efficiency. In addition, the rod material is not subjected to pressure and relies on its own gravity friction, so the polishing efficiency is not high and it takes a long time.

[0029] In a specific embodiment: during adjustment, the connection between the third side plate 6 and the first side plate 2 is released by bolts, and the position of the third side plate 6 is adjusted by the screw rod 9 below, thereby changing the gap between the first side plate 2 and the third side plate 6 to adapt to rods of different lengths.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the rod polishing machine includes a feeding device, which includes a connecting rod 8, a slide rail 11 and a movable plate 12. The connecting rod 8 is arranged on the base frame 1 and is powered by a belt group and connected to the first motor 7. The slide rail 11 is arranged on the base frame 1 and is located between the first side plate 2 and the third side plate 6. The movable plate 12 is slidably installed on the slide rail 11. The movable plate 12 is powered by the connecting rod 8, and a plurality of ratchet-shaped protrusions are provided above the movable plate 12.

[0031] In a specific embodiment: when in use, the rods to be polished are placed in the material bin formed by the first side plate 2 and the third side plate 6, and the connecting rod 8 is driven by the second motor 24, so that the connecting rod 8 pushes the movable plate 12 to reciprocate on the slide rail 11, and the ratchet-shaped protrusions on the movable plate 12 drive the rods to move in one direction, thereby continuously feeding the rods.

[0035] During the process, the feeding speed can be changed by adjusting the height of the first partition 22. At the same time, due to the limitation of the feeding speed by the first partition 22, new rods can be continuously added to the silo. Different from the traditional manual intermittent feeding, it realizes flow operation, thereby greatly improving efficiency.

[0036] like Figure 3 , Figure 4 and Figure 5 As shown, the rod polishing machine includes a polishing device, which includes a second side plate 3, a polishing roller 10, a cover plate 4 and a second partition plate 23. The second side plate 3 is hinged to one end of the first side plate 2. The polishing roller 10 is installed on the base frame 1 through a support frame and is located between the second side plate 3 and the third side plate 6. The polishing roller 10 is powered by a belt group and is connected to the first motor 7. The polishing roller 10 is ratchet-shaped. The cover plate 4 is hinged to the top of the base frame 1 through a support frame and is located above the polishing roller 10. A state sensor is provided above the cover plate 4. The state sensor can detect the opening state of the cover plate 4 and automatically stop the machine when the cover plate 4 is opened, thereby providing safety protection. The second partition plate 23 is supported at the end of the second side plate 3, and the second partition plate 23 can adjust the height.

[0037] In a specific embodiment, the rod material fed in by the feeding device is driven to rotate under the action of the polishing roller 10, so as to be polished by mutual friction and extrusion.

[0038] When in use, the discharge speed of the rod material in the polishing device can be controlled by adjusting the height of the second partition plate 23, thereby controlling the polishing time and polishing degree.

[0039] like Figure 5 and Figure 6 As shown, the bar polishing machine includes a discharging device, which includes a first mounting plate 13, a guide plate 14, a pulley 15, a support assembly, a chain belt 20, a limit plate 21 and a second motor 24.

[0040] In a specific embodiment: when in use, the second motor 24 drives the chain belt 20 to rotate, and the pulley 15 drives the cam 16 to rotate, thereby intermittently lifting the upper roller and the guide plate 14, so that the guide plate 14 vibrates, and the polished wood above is shaken and separated. At the same time, the middle part of the separated rod material will fall into the slot of the chain belt 20, so that the material is discharged under the rotation of the chain belt 20. During this process, the second support plate 18 will support both ends of the rod material to prevent the rod material from falling between the protrusions of the chain belt 20 to avoid blockage.

[0041] During use, the position of the upper end of the limit plate 21 can be adjusted by means of bolts, thereby controlling the discharge position of the bar material, which is convenient for docking with the next processing link.

At the same time, the middle part of the separated rod will fall into the slot of the chain belt 20, so that it can be discharged under the rotation of the chain belt 20. During this process, the second support plate 18 will support both ends of the rod to prevent the rod from falling between the protrusions of the chain belt 20 to avoid blockage.
