Specifically, the transmission assembly 3 and the grinding brush 2 at the left end can grind and polish the lower surface of the part to be ground and polished, the part to be ground and polished moves out from the outlet end of the transmission assembly 3 and enters from the inlet end of the transmission assembly 3 at the right end, and the transmission assembly 3 at the right end can grind and polish the upper surface of the part to be ground and polished and finally moves out from the outlet end of the transmission assembly 3 at the right end. This structure, through setting up two drive assembly 3, and with two drive assembly 3 realization upper and lower corresponding settings, can treat to grind to throw the piece and carry out two-sided mill and throw, and then improve and grind and throw efficiency.

And each transmission assembly 3 is provided with two spray heads 6 for supplying water to each grinding brush 2, the spray heads 6 are preferably arranged at the left side and the right side of the corresponding grinding brush 2 respectively, and the water spray nozzle of each spray head 6 points to the joint of the corresponding grinding brush 2 and the corresponding conveyor belt 32.

In other embodiments, the number of the transmission assemblies 3 may also be multiple, and the two transmission assemblies 3 are arranged according to the arrangement mode of the two transmission assemblies 3, so that the two surfaces of the workpiece to be polished can be repeatedly polished, and the polishing effect of the workpiece to be polished is further improved, which is not limited herein.

Further, referring to fig. 1, as an embodiment of the plate grinding machine provided by the embodiment of the present invention, the conveyor belt 32 at the lower end of one transmission assembly 3 is aligned with the conveyor belt 32 at the upper end of the other transmission assembly 3. Specifically, the conveyor belt 32 at the lower end of the left-end transmission assembly 3 is parallel and collinear with the conveyor belt 32 at the upper end of the right-end transmission assembly 3. According to the structure, the part to be polished coming out of the transmission assembly 3 at the left end can enter the transmission assembly 3 at the right end along a straight line, so that the double-sided polishing effect of the part to be polished is consistent, the polishing effect of the part to be polished is good, and the appearance effect of a product is good.

The following table shows the use of the conveyor belt 32 and the wear of the pallet 4 after 12 months of experiments in the case of a pallet 4 of a grinder, both without the provision of the recess 411 (before modification) and with the provision of the recess 411 (after modification).

(1) Use of the conveyor belt 32

Before the improvement: the conveyor belt 32 is used for 1 month, has no defects of looseness, abrasion and the like, and can be normally used; the conveyor belt 32 will slightly relax after 2-3 months of use, but normal use is not affected; when the conveyor belt 32 is used for 4-7 months, the conveyor belt 32 is seriously loosened, and the conveyor belt 32 can be normally used only after the plate grinding machine is debugged; when the using time of the conveyor belt 32 exceeds 7 months, the conveyor belt 32 cannot be normally used and needs to be replaced in time.

After the improvement: the conveyor belt 32 has good use effect, has no loose abrasion phenomenon and does not need debugging or replacement within the service life of 12 months.

(2) Wear of the pallet 4

Before the improvement: the supporting plate 4 is used for 1 month, the abrasion of the friction surface between the supporting plate 4 and the conveyor belt 32 is not obvious, and the supporting plate can be normally used; when the supporting plate 4 is used for 2-3 months, the friction surface of the supporting plate 4 and the conveyor belt 32 is slightly worn, and the grinding and polishing effect of a part to be ground and polished is not influenced; when the supporting plate 4 is used for 4-5 months, the friction surface between the supporting plate 4 and the conveyor belt 32 is in medium abrasion, and the grinding and polishing effect of a part to be ground and polished is reduced; after the supporting plate 4 is used for 6-7 months, the friction surface between the supporting plate 4 and the conveyor belt 32 is seriously worn, and the grinding and polishing effect of a part to be ground and polished is seriously reduced; when the pallet 4 is used for more than 7 months, the surface of the pallet 4 and the conveyor belt 32 has obvious defects such as abrasion pits, scratches and the like, and the pallet 4 is unusable.

After the improvement: the supporting plate 4 has good use effect in the service life of 12 months, the friction surface of the supporting plate 4 and the conveyor belt 32 has no obvious abrasion pits or scratches, the surface flatness is good, debugging or replacement is not needed, and the polishing effect of the to-be-polished part is good.

In summary, the supporting plate 4 of the conventional plate grinding machine is not provided with the groove 411, so that the conveyor belt 32 is usually required to be replaced and debugged after being used for 4-7 months, and the maximum service life of the conveyor belt 32 is 7 months; along with the increase of the service life of the supporting plate 4, the abrasion of the friction surface of the supporting plate 4 and the conveyor belt 32 is gradually deepened, the defects of abrasion pits, scratches, surface flatness reduction and the like can occur, and the maximum service life of the supporting plate 4 is 7 months.

The improved plate grinding machine is provided with the groove 411 on the supporting plate 4, the conveyor belt 32 is used for more than one year without debugging or replacement, the abrasion of the friction surface of the supporting plate 4 and the conveyor belt 32 is not obvious, the using effect of the supporting plate 4 is good, and the grinding and polishing effect of a part to be ground and polished is good. Therefore, the service life of the conveyor belt 32 and the supporting plate 4 can be greatly prolonged by arranging the groove 411 on the supporting plate 4, and the utilization rate of the plate grinding machine is further improved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
