Description

Technical Field

[0001] The utility model relates to the technical field of centerless grinders, in particular to a centerless grinder with automatic feeding and discharging of materials. Background Art

[0002] Centerless grinders are a type of grinder that does not require the axis of the workpiece to perform grinding. They are widely used in the field of mechanical processing. For example, in the field of stainless steel production, in order to obtain stainless steel bars with ideal smoothness, or to make adjustments to meet tolerance requirements, centerless grinders are required for processing.

[0003] Existing centerless grinders can only process smaller workpieces. The processed workpieces are not fine, and the force when grinding the workpieces is not strong enough. After the centerless grinder completes the grinding of the workpiece, the temperature of the workpiece increases. If the staff directly pick up the workpiece with their hands, they are easily burned and it is manpower-consuming.

[0004] The existing patent (publication number: CN216264982U) is a centerless grinder with automatic feeding and unloading, including a motor box and a ceiling. By providing a roller mechanism, when the second roller and the first roller grind the workpiece, the first spring rod on the top of the second roller will continuously squeeze the second roller, thereby increasing the grinding force of the second roller through squeezing, and because the second roller is obliquely laid on the inner wall of the ceiling, the device can process larger workpieces. By providing a collecting mechanism, the workpiece will fall from the ceiling into the collection box after processing, which is convenient for cooling the overheated workpiece after processing. When the collection box is full, the workpiece will also fall from the collection box into the collection box, which is convenient for the staff to collect the workpiece, and the staff can push the workpiece by pushing the push plate. While the workpiece is being pushed, the workpiece debris remaining on the outer wall of the workpiece will also be pushed, and the pushed debris will fall into the collection box through the slot, and the staff only needs to clean the collection box regularly.

[0005] However, the above technical solution still has certain shortcomings. Workers are required to operate when loading materials, and when unloading the workpiece, workers are required to push the push rod to unload the workpiece. Workers need to wait next to the grinder for a long time, which makes them overworked, resulting in reduced efficiency and affecting the grinding efficiency of the grinder. Utility Model Content
