Description

Food processor with stable operation Technical Field The invention relates to the technical field of food processing devices, in particular to a food processor with stable operation. Background An existing food processor, such as a meat grinder capable of dough kneading, is provided with a dough kneading rod arranged in a meat mincing cup, the meat mincing cup cover covers the upper opening part of the meat mincing cup, and a host is arranged above the meat mincing cup cover. When the food processor is used for dough kneading, the motor in the main machine drives the dough kneading rod to rotate through the speed reduction of the secondary reduction gearbox, so that food materials in the minced steak cup are stirred. The main machine is driven by duplex gears, a fixed gear ring, duplex gears, a movable gear ring and a planet carrier which are matched with each other are arranged in a reduction gearbox, the duplex gears comprise an upper gear meshed with the fixed gear ring and a lower gear meshed with the movable gear ring, a motor shaft is transmitted to the upper gear through a sun gear, the lower gear drives the planet carrier and the movable gear ring to rotate respectively, and therefore two-stage output is formed, the movable gear ring is meshed with a dough kneading rod after two-stage reduction is achieved through the planet carrier and the duplex gears, and a higher rotating speed of the planet carrier output can be used for driving a meat mincing knife. Under dough mixing working condition, dough is distributed on one side of the minced steak cup after being clustered, and the position is continuously adjusted in the stirring process, so that the dough forms larger radial force on the dough mixing rod in the working process, the radial force is transmitted to the inner wall of the shell of the reduction gearbox through the movable gear ring, the whole reduction gearbox bears the radial force transmitted by the lower part and the dough mixing rod in the operation meshing process, and the movable gear ring forms deflection in the working process. Because the upper gear of duplex tooth meshes with the fixed gear ring, the lower gear meshes with the movable gear ring of certain deflection, and the whole of duplex tooth receives great deflection force, make whole reducing gear box noise big, the gear shaft of duplex tooth is along axial direction by being located upper bracket and the lower carriage at duplex tooth both ends respectively and do axial and radial spacing, the shaft hole of duplex tooth and the little clearance fit of gear shaft, when the duplex tooth received great deflection force, the gear shaft can do certain correction to duplex tooth deflection, but when gear shaft and shaft hole long-time because of moving gear ring deflection and causing duplex gear to receive deflection force and lead to gear shaft and duplex gear center shaft hole to take place the reaming problem. Once the reaming problem occurs, the centering correction effect of the intermediate gear shaft on the duplex gear is lost, the deflection of the duplex gear is more aggravated, the end faces of the duplex gear and the upper end face and the lower end face of the brackets at the two ends of the gear can be further crushed, and therefore the overall durability of the reduction gearbox is invalid, and the working stability of the whole machine is affected.
