[0023] Example 1

[0024] like Figure 1 , Figure 2 As shown, this is an embodiment of the present invention, specifically: a stone polishing machine, including a material tray 1 and a polishing tray 2, the material tray 1 is provided with a loading plane 11, and a loading space 12 for loading stone is provided between the loading plane 11 and the polishing tray 2; it also includes an eccentric driving device for driving the material tray 1 to rotate eccentrically, and the material tray 1 has an eccentric motion path parallel to the loading plane 11; the eccentric driving device includes an eccentric driving mechanism, and the eccentric driving mechanism includes a rotating driving body 32 provided with a first rotating shaft 31, and the axial direction of the first rotating shaft 31 is arranged perpendicular to the loading plane 11; the eccentric driving device also includes a first connecting body 33, one end of the first connecting body 33 is fixedly connected to the first rotating shaft 31, and the other end of the first connecting body 33 is pivotally connected to the side of the material tray 1. Figure 1 In the embodiment shown, the polishing plate 2 and the material plate 1 are arranged in parallel, and the polishing plate 2 is located above the material plate 1. Figure 2As shown, under the action of the rotating driving body 32, the first rotating shaft 31, and the first connecting body 33, the side portion of the material tray 1 connected to the first connecting body 33 generates an eccentric rotation as shown by the arrow direction. The material tray 1 has an eccentric motion path parallel to the loading plane 11, which enables a larger area of ​​the loaded stone to be contacted by the polishing disc 2, thereby reducing the number of times the stone is clamped.

[0025] Example 2

[0026] Different from the first embodiment, the eccentric drive device further includes at least one driven mechanism; the driven mechanism includes a fixed shaft 41, the axis direction of the fixed shaft 41 is perpendicular to the loading plane 11; the driven mechanism further includes a second connecting body 42, one end of the second connecting body 42 is pivotally connected to the fixed shaft 41, and the other end of the second connecting body 42 is pivotally connected to the side of the material tray 1. The driven mechanism ensures the eccentric movement of the material tray 1.

[0027] As a further preferred embodiment, the eccentric driving mechanism and at least one driven mechanism are evenly distributed along the circumference of the material tray 1, so that the circumferential force points of the material tray 1 are more uniform, thereby increasing the service life of the stone polishing machine.

[0028] Example 3

[0029] Different from Example 1, the stone polishing machine also includes a polishing liquid circulation device, which includes a nozzle 51 for outputting polishing liquid to the carrying space 12, a recovery channel 52 arranged on the polishing disc 2, and a circulation pipeline connected to the recovery channel 52. The circulation pipeline is provided with a liquid driving device 53 for driving the polishing liquid from the recovery channel 52 to the nozzle 51. The polishing liquid circulation device enables the polishing liquid to be recycled, reducing the loss of raw materials. The liquid driving device 53 can be configured to include a containing box and a liquid pump, and the containing box is arranged below the material tray, so that the polishing liquid can flow into the containing box by its own weight, reducing the energy loss of the liquid circulation. The liquid pump then transports the liquid in the containing box to the nozzle 51.

[0030] As a further preferred embodiment, the recovery channel 52 is configured as a through hole, which passes through the material tray 1 in the thickness direction, so as to better utilize the dead weight of the polishing liquid to recover the polishing liquid.

[0031] Example 4

[0032] Different from the third embodiment, the nozzle 51 is fixedly connected to the material tray 1, and the nozzle 51 is provided with a liquid outlet arranged toward the polishing tray 2, that is, the nozzle 51 can spray the polishing liquid onto the polishing tray 2. The material tray 1 has an eccentric motion path parallel to the loading plane 11, and can be used to drive the stone to produce eccentric motion, that is, the polishing tray 2 also moves eccentrically relative to the stone, so the nozzle 51 can be arranged to spray the polishing liquid onto the part of the polishing tray 2 that moves eccentrically and away from the stone, and the polishing liquid then flows along the polishing surface of the polishing tray 2 to the stone, so that the polishing liquid can better enter between the polishing tray 2 and the stone, and improve the use effect of the polishing liquid.

[0033] Example 5

[0034] Different from the first embodiment, the stone polishing machine further comprises a polishing drive device for driving the polishing disc 2 to move, the polishing drive device comprises a rotation drive device for driving the polishing disc 2 to rotate, the rotation drive device comprises a rotation drive body 61 and a second rotation shaft 62, the second rotation shaft 62 is circumferentially fixedly connected to the polishing disc 2; the polishing drive device further comprises an axial drive device for driving the polishing disc 2 to move along the axial direction of the second rotation shaft 62. The second rotation shaft 62 is circumferentially fixedly connected to the polishing disc 2, that is, the polishing disc 2 is circumferentially fixed, which can ensure the stability of the rotational motion. The axial drive device can move the polishing disc 2 closer to the stone, increase the contact pressure between the polishing disc 2 and the stone, and further improve the polishing efficiency.

[0035] As a further preferred embodiment, the axial drive device includes an axial drive body and a telescopic mechanism 63 driven by the axial drive body, the telescopic direction of the telescopic mechanism 63 is arranged along the axial direction of the second rotating shaft 62, one end of the telescopic mechanism 63 is fixedly connected to the second rotating shaft 62, and the other end of the telescopic mechanism 63 is fixedly connected to the polishing disc 2. The axial drive body can be arranged as a cylinder to provide a more stable axial driving force. The telescopic mechanism 63 can be arranged to be driven by the output shaft of the cylinder to telescope, thereby driving the polishing disc 2 to move.

[0036] Example 6

[0037] What is different from Example 1 is that the first rotating shaft 31 has a forward rotation direction and a reverse rotation direction, so that the polishing disc 2 can both increase the relative rotation speed of the polishing disc 2 and the material disc 1 and the stone, and reduce the relative rotation speed of the polishing disc 2 and the material disc 1 and the stone, thereby increasing the adjustment range of the polishing rate and making the polishing rate adjustment more flexible.

[0038] At least two blocking bodies are arranged on the material tray 1, and at least two blocking bodies are arranged along the circumference of the material tray 1; the blocking bodies include a first vertical plate 71 and a second vertical plate 72 for abutting against the stone, the side of the first vertical plate 71 is fixedly connected to the plate plane of the second vertical plate 72, and a buffer body 73 is arranged on the plate plane of the second vertical plate 72 away from the first vertical plate 71.

The buffer body 73 can be set as a sponge, cotton cloth, etc. At least two blocking bodies are arranged along the circumference of the material tray 1, which can simultaneously cope with the forward and reverse rotation of the material tray 1 caused by the first rotating shaft 31, thereby improving the protection of the stone.
