Description

Technical Field

[0001] The utility model belongs to the technical field of numerical control machine tools and relates to a feeding mechanism of a numerical control machine tool. Background Art

[0002] A CNC lathe is a high-performance, high-precision, low-noise, walk-behind machine tool. It is an automatic processing machine tool that uses a numerical control system to control the processing program. When processing materials, CNC machine tools require a material feeding mechanism.

[0003] An automatic CNC machine tool feeding device disclosed in Chinese patent CN218808684U, when the feeding device is used, first pour the material into the storage box, at this time the material is on the partition, and then the solenoid valve is opened to allow the material to enter the storage box. At this time, the pressure sensor detects the weight of the material. When the material reaches the preset value, the pressure sensor transmits the signal to the control panel, the control panel controls the solenoid valve to close, and then the first electric push rod is used to open the door body, so that the material falls onto the conveyor belt, which can accurately control the unloading of the material and improve the feeding efficiency.

[0004] After long-term use, the conveyor belt of this feeding device will accumulate dust and impurities, so the conveyor belt needs to be cleaned. Water is directly pumped out of the water tank through the water pump, and the water enters the nozzle through the first connecting pipe and the second connecting pipe. The water is sprayed onto the conveyor belt through the nozzle and cleaned with a brush. When using water for flushing, dust and impurities will flow into the feeding mechanism with the water, and the water will also splash onto the entire feeding mechanism. The feeding mechanism needs to be completely air-dried before it can be used again, which affects the use of the feeding mechanism. If only a brush is used for cleaning without adding water, the impurities removed by the brush tend to accumulate on one side of the brush, making it difficult to collect.
