In existing glass cover polishing machines, the longitudinal distance between the tensioning wheel and the driving and driven wheels is relatively large, resulting in a large space occupation of the equipment, and the uneven spraying of polishing liquid affects the polishing effect.
Multiple tensioning rollers arranged side by side are used instead of a single tensioning roller, and a transfer valve and liquid outlet are set on the support to achieve uniform spraying of polishing fluid and full coverage wetting of the glass cover plate. At the same time, the longitudinal space occupied by the equipment is reduced by the design of synchronous belt and rotating wheel.
This design achieves a compact layout and better polishing results, improving ease of use and polishing efficiency.

[0028] In one embodiment, the outer side of the cabinet 10 is provided with a rack 50, the top of the rack 50 is provided with a servo motor 51, and the rack 50 is provided with a screw rod 52 and a screw rod slider. The output shaft of the servo motor 51 is coaxially connected to the screw rod 52 to drive the screw rod 52 to rotate in a direction. The screw rod 52 extends vertically, and the screw rod slider is threadedly connected to the screw rod 52. The rack 50 and the screw rod slider are slidably connected through a vertical guide structure. When the screw rod 52 rotates, the screw rod slider moves up and down along the screw rod 52 based on the sliding connection and the threaded connection. The vertical guide structure can include a guide rail provided on the rack 50 and a guide rail slider provided on the screw rod slider and slidably connected to the guide rail.

The rotating shaft of the lower rotating motor 11 is coaxially connected to the wheel shaft of the second driving wheel 32 to drive the directional rotation of the second driving wheel 32, which in turn drives the directional rotation of the lower polishing belt 30 through the cooperation of the second driven wheel 33 to polish the bottom surface of the glass cover plate. The lower support 12 is located between the second driving wheel 32 and the second driven wheel 33 and has a second smooth bottom surface 121. The lower support 12 abuts against the upper inner surface of the lower polishing belt 30 through the second smooth bottom surface 121. The second support 12 is provided with a second adapter valve 122 for connecting external polishing liquid. The second smooth bottom surface 121 is provided with a plurality of second liquid outlets 101.

[0032] The first adapter valve 552 and the second adapter valve 122 can be three-way valves.
[0033] In one embodiment, the cabinet 10 is provided with two rotating wheels 60 for driving the directional rotation of the glass cover plate carrier 40. The circumferential side of the glass cover plate carrier 40 is provided with teeth that engage with the gear teeth 63 of the rotating wheels 60. The wheel shaft of any rotating wheel 40 is coaxially connected to a carrier motor, and the wheel shafts of the two rotating wheels 60 are drivingly connected through a synchronous belt 61. In addition, the cabinet 10 is provided with two tensioning wheels 62 on the outer surface of the synchronous belt 61. The two tensioning wheels 62 are distributed on the same side along the rotation direction of the synchronous belt 61 to tension the synchronous belt 61. This can reduce the transverse occupation space of the device at the synchronous belt 61, so that the overall structure of the device can be more compact, or the device can be more conveniently arranged at the synchronous belt 61, and the use is more convenient.
