Description

Technical Field

[0001] The invention belongs to the technical field of metal processing equipment, and in particular relates to a metal plate surface grinding machine. Background Art

[0002] The metal plate surface grinder is a mechanical device used for surface treatment of metal plates. It is mainly used to remove rust, oxide layer, old coating or burr on the metal surface and improve the surface finish. The surface grinding of metal plates usually requires double-sided grinding, but traditional grinders are usually used for single-sided grinding. After one side of the metal plate is polished, it needs to be manually turned over and put into the grinder for grinding again. If the metal plates are polished in large quantities, such operation will have low production efficiency. The double-sided grinders on the market are usually expensive and have high maintenance costs, which increases the production costs of enterprises.

[0003] Impurities such as metal debris generated by traditional grinders during the grinding process may adhere to the surface of the metal plate, which greatly affects the effect of coating treatments such as painting after the metal plate is ground, and affects the quality of the product. Therefore, a metal plate surface grinder with good cleaning effect and double-sided grinding is needed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a metal plate surface grinder. The present invention can allow the metal plate to automatically flip over during the conveying process of multi-pass grinding to achieve the effect of double-sided grinding, and can effectively clean impurities on the surface of the metal plate during the multi-pass grinding process. Combined with the comprehensive cleaning of the metal plate during the flipping process, the cleaning effect of the metal plate is effectively guaranteed to prevent the metal plate from sticking to impurities such as metal debris, which affects the final product quality of the metal plate.

[0005] The technical solution adopted to solve the above technical problems is: a metal plate surface grinder, comprising a clamp mechanism, a limit shell and a driving mechanism, wherein the clamp mechanism is slidably connected to the driving mechanism, the limit shell is arranged above the clamp mechanism, the driving mechanism can drive the clamp mechanism to move horizontally, a feeding platform is fixedly arranged at the front end of the limit shell, a first grinding component is fixedly arranged at the front end of the feeding platform, a dust cleaning bin is fixedly arranged at the front end of the first grinding component, and a second grinding component is fixedly arranged at the front end of the dust cleaning bin; The feeding platform, the first grinding assembly and the second grinding assembly are all provided with a passage allowing the clamp mechanism to pass through; The clamp mechanism can clamp the metal plate to be processed, and the clamp mechanism can drive the metal plate to be processed to pass through the first grinding component, the dust cleaning bin and the second grinding component; When the clamp mechanism clamps the metal plate to be processed and passes through the dust cleaning bin, it can drive the metal plate to be processed to flip.

When passing through the cleaning bin, the clamping mechanism drives the metal plate to be processed to flip over, so that the first grinding component grinds the front side of the metal plate to be processed, and the second grinding component grinds the back side of the metal plate to be processed. When the metal plate to be processed is flipped in the cleaning bin, the cleaning bin can comprehensively clean the metal plate to be processed. Compared with the traditional processing method in which the metal plate is in a horizontal state for cleaning, the cleaning effect is more thorough. After the grinding is completed, the driving mechanism drives the clamping mechanism to return. After the metal plate to be processed falls into the feeding platform, it is output from the side of the feeding platform, and the grinding processing of the metal plate to be processed is completed.

The metal plate 9 to be processed is turned over before entering the second grinding assembly 6, so that the first grinding assembly 5 grinds the front side of the metal plate 9 to be processed, and the second grinding assembly 6 grinds the back side of the metal plate 9 to be processed. During the grinding process, an air compressor can be connected through the air inlet connector 17 to allow the blowing slot 18 to blow out high-pressure air to blow air to both sides of the metal plate 9 to be processed, which can effectively blow metal debris and other impurities out of the metal plate 9 to be processed, thereby preventing the metal plate 9 from being adhered to impurities; When the metal plate 9 to be processed is turned over in the dust cleaning bin 7, the air blower joint 82 can be connected to the blower, so that the air jet port 71 can perform air jet cleaning on the metal plate 9 to be processed, so that the air jet port 71 can fully clean the metal plate 9 to be processed. Compared with the air jet cleaning when the metal plate 9 to be processed is horizontal, the cleaning effect is more thorough. Wind curtains can also be hung at the front and rear ends of the dust cleaning bin 7 to prevent air from being blown out of the dust cleaning bin 7, thereby improving the cleaning effect and preventing impurities from splashing. After the metal plate 9 to be processed is polished, the driving mechanism 3 drives the clamping mechanism 1 to retract horizontally. After the metal plate 9 to be processed enters the feeding platform 4, the electric push rod 142 adjusts the distance between the upper clamping plate 15 and the lower clamping plate 16, so that the metal plate 9 to be processed after polishing is placed in the feeding platform 4, and then discharged from the side of the feeding platform 4; After the first grinding component 5 completes the front grinding of the metal plate 9, it enters the cleaning bin 7 for flipping and cleaning. Then, after the second grinding component 6 completes the back grinding of the metal plate 9, the metal plate 9 passes through the cleaning bin 7 during the return process and can be flipped and cleaned again, which effectively ensures the cleaning effect and improves product quality.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
