With the continuous improvement of people's living standards, the requirements for food are also gradually increasing, which not only includes the deliciousness and nutritional value of food, but also the appearance requirements. Among the meringue methods currently on the market, the method of frying meringues is purely manual. The frying and mixing steps of meringue are simply divided into the following steps: 1. Stir eggs and sugar fully; 2. Heat the oil in the oil pan, pour the mixed egg liquid into the hot oil; 3. Mix the egg liquid After the oil is poured in, the worker operates the spoon to make a series of actions. A set of movements are all manually operated. Workers suffer from backaches and health damage all day long, and workers cannot accurately grasp the strength and time of stirring. They are all determined by experience. The oil in the pot is spilled outside, which directly causes waste; at the same time, a large number of unqualified meringues are wasted, and the output is very low and the quality cannot be guaranteed.

The working principle of the present invention: the meringue automatic frying and mixing device is composed of gray cast iron 22, profiles and lower bottom plate 18 to form a support part 21, three 86 stepping motors and a reduction box to form a power part, and the part above the lower bottom plate 18 to form a mechanical arm 37 . The mechanical arm 37 adopts a parallelogram four-bar linkage mechanism to realize the forward and backward movement of the spoon 2 in the oil pan 3. On the first motor reduction box 19, a motor gear 34 with a modulus of 1 and a number of teeth of 20 is driven by external engagement. A slewing bearing 33 with a modulus of 1 and a number of teeth of 106 realizes the left and right movement of the upper base plate 17, thereby realizing the left and right movement of the spoon 2.

To realize the movement of the spoon 2 in the vertical direction can be realized in the following manner. Upward movement: the second motor 16 rotates clockwise, driving the second motor reducer 14 to rotate clockwise, the output shaft of the second motor reducer 14 drives the b coupling 35 to move, and finally drives the boom assembly 29 to rotate clockwise, also That is to say, the process of realizing the lifting of the B and C booms.

The output shaft of the third motor reduction box 32 drives the c-coupling 30, and the c-coupling 30 drives the stepped shaft 36 to rotate, so that the a-coupling 31 on the stepped shaft 36 rotates clockwise, and finally realizes the clockwise rotation of the a-connecting rod 13.
