A rotating shaft 24 is rotatably connected to one side of the driving plate 21, and the rotating shaft 24 is transmission-connected to the motor 22 through gears. A grinding roller 25 is sleeved on the surface of the rotating shaft 24; two arc holes 27 corresponding to the two gear boxes 23 are opened inside the driving plate 21, and a central shaft 231 penetrating the arc holes 27 and extending to one side of the driving plate 21 is provided on one side of the driving plate 21. A transmission rod 28 sleeved with the central shaft 231 is movably provided on one side of the driving plate 21, and an adjusting screw 29 is sleeved on the internal thread of the transmission rod 28.

[0024] Specifically, the two central shafts 231 are coaxially arranged with the two rotating shafts 24 respectively, a graphite slip ring 251 is movably embedded inside one end of the grinding roller 25, and a bolt 26 with one end fitted with the graphite slip ring 251 is threadedly sleeved at one end of the rotating shaft 24. The bolt 26 is used to lock the grinding roller 25. The setting of the graphite slip ring 251 reduces the pressure loss caused by the bolt 26 on the end of the grinding roller 25.

[0025] Specifically, a fixing block 211 is disposed on one side of the driving plate 21 , and one end of the adjusting screw 29 is rotatably disposed inside the fixing block 211 through a bearing. The fixing block 211 is disposed for mounting the adjusting screw 29 .

The setting of the slider further ensures the stability of the center shaft 231. When it is necessary to adjust the spacing between the two grinding rollers 25, the adjusting screw 29 is rotated to squeeze the transmission rod 28 to move forward or backward horizontally. At the same time, the transmission rod 28 drives the center shaft 231 to slide inside the arc hole 27 through the waist-shaped hole 281. At the same time, the center shaft 231 slides inside the waist-shaped hole 281 through the slider for adaptation, thereby realizing the adjustment of the spacing between the two grinding rollers 25, and can adapt to the grinding of synthetic leather or leather of different thicknesses.

[0027] Specifically, the two arc-shaped holes 27 are respectively aligned with the centers of the two output ends of the motors 22, see Figure 1 The gear box 23 is internally provided with two gears connected by a chain or a toothed belt drive, and the two gears are respectively connected to the output end of the motor 22 and the rotating shaft 24, so that when the motor 22 is started, the motor 22 drives the rotating shaft 24 to rotate.

The setting of the stabilizing rod 282, in conjunction with the fixing seat 212, makes the transmission rod 28 more stable when it moves.

[0029] Specifically, two support plates 12 are symmetrically arranged at both ends of the top of the bottom plate 1, and a clamping plate 13 is arranged on the top of the support plate 12 through a screw. The screw is removed to place the polished synthetic leather between the clamping plate 13 and the support plate 12, and finally locked by the screw.

[0030] To sum up, the grinding device for synthetic leather production drives the transmission rod 28 to move by rotating the adjusting screw 29. The transmission rod 28 can drive the two center shafts 231 to slide inside the arc hole 27. The center shaft 231 drives the two grinding rollers 25 to move for spacing adjustment. According to the rotation direction of the adjusting screw 29, the two grinding rollers 25 are moved closer to or farther away from each other to adapt to synthetic leathers of different thicknesses, which is more convenient to use.
