Description
Technical Field
[0001] The invention relates to the technical field of cooking machines, in particular to a mechanical arm cooking machine with a transmission shaft sealing structure. Background Art
[0002] As the pace of life accelerates, people increasingly hope to cook delicious dishes more conveniently and efficiently. At the same time, the continuous progress of electronic technology, sensor technology, and automatic control technology has provided technical support for the research and development and production of cooking machines. For example, accurate temperature sensors can monitor and feedback the temperature in the pot in real time, so that the control system can accurately adjust the heating power.
[0003] People are paying more and more attention to healthy diet and balanced nutrition, and hope to better control the amount of oil and salt used in the cooking process. The catering industry is facing problems such as rising labor costs, shortage of chef resources, and standardization of food quality. Stir-frying machines can provide standardized cooking processes, ensure the consistency of food taste, improve food delivery efficiency, and reduce labor costs. Therefore, they are attracting the attention and demand of catering companies.
[0004] The cooking machine can efficiently and stably prepare takeaway dishes, ensuring the rapid delivery of orders and the stability of the quality of dishes, which helps to improve the competitiveness of the takeaway business. At the same time, the cooking machine used in school canteens can cook a large number of dishes at the same time to meet the dining needs of students, and can ensure the nutritional balance and stable taste of the dishes, which is convenient for the canteen to carry out unified management and cost control.
[0005] The transmission shaft sealing structure usually includes a mounting ring, an inner seal, an outer seal and a possible sealing kit. The mounting ring is mounted on the transmission shaft, the inner seal is mounted in the inner mounting groove of the mounting ring and abuts against the transmission shaft, and the outer seal is mounted in the outer mounting groove and abuts against the mounting structure, thereby forming a seal between the transmission shaft and the mounting structure to prevent leakage of oil, water, etc. Some transmission shaft devices are also provided with an observation notch to facilitate observation of whether the seal has failed.
[0006] The robotic arm is composed of multiple joints and connecting rods, and can achieve multi-degree-of-freedom motion through motors, reducers and other driving devices. The motion trajectory, speed and strength of the robotic arm can be precisely controlled to simulate the stir-frying, mixing, adding ingredients and other actions of human chefs.
[0007] The robotic arm has high-precision positioning and control capabilities, and can accurately control the strength, angle and speed of stir-frying to ensure that the ingredients are evenly heated, improve the cooking quality, and ensure that the color, aroma and shape of each dish are highly consistent. The robotic arm can achieve a variety of cooking operations such as stir-frying, cutting, stirring, frying, deep-frying, etc. by replacing different tools or accessories, such as stirring spatulas and knives, to meet diverse cooking needs.
