In order to determine the basic size of the main parts of the fabric rolling machine, the following 5 tasks must be done:
1) Kinematics design of fabric rolling machine. According to the determined structural scheme, determine the parameters of the original moving part (power, rotational speed, linear speed, etc.). Then do kinematic calculations to determine the motion parameters (speed, speed, acceleration, etc.) of each moving component.
2) Dynamic calculation of fabric rolling machine. Combined with the structure and motion parameters of each part of the cloth winding machine, the magnitude and characteristics of the load on each main part are calculated. The load obtained at this time is only the nominal (or nominal) load acting on the part because the part has not been designed.
3) The working capacity design of the parts. The preliminary design of parts and components can be done if the size and characteristics of the nominal load on the main parts are known. The working capacity criteria based on the design of the fabric rolling machine must be reasonably formulated with reference to the general failure conditions, working characteristics, and environmental conditions of parts and components. Generally, there are criteria such as strength, stiffness, vibration stability, and life. By calculation or analogy, the basic dimensions of parts and components can be determined. the
4) Design of component assembly sketches and general assembly sketches. According to the basic dimensions of the main parts and components that have been determined, the assembly sketches of the cloth winding machine components and the general assembly sketches are designed. The outline and dimensions of all parts need to be structurally designed on the sketch. In this step, it is necessary to coordinate the structure and size of each part of the cloth winding machine well, and comprehensively consider the structural manufacturability of the designed parts and components, so that all parts have the most reasonable configuration.
5) Checking of main parts. For some parts, in the above step 3), due to the undecided specific structure, it is difficult to carry out detailed work capacity calculation, so only preliminary calculation and design can be done. After the component assembly sketch and the general assembly sketch are drawn, the structure and size of all parts are known, and the relationship between adjacent parts is also known. Only at this time can the load acting on the part be determined more accurately, and various detailed factors that affect the working ability of the part can be determined. Only under this condition, it is possible and necessary to carry out accurate check calculations for some important parts or parts with complex shapes and stress conditions. According to the results of the check, modify the structure and size of the fabric winder parts repeatedly until satisfactory.
