[0067] The relationship between the vibration frequency of the vibration plate 401 and the spring feeding speed is calculated by the following formula:

[0068] v = f * d * 1000;

[0069] The vibration frequency of the vibration plate 401 is f (Hz), and the distance the spring moves each time is d (mm). Then the feeding speed of the spring per unit time is v (mm / s);

[0070] The frequency f is usually determined by the rotation speed of the vibration motor 402 , while d depends on the design of the vibration plate 401 and the elastic coefficient of the spring.

[0071] The relationship formula between the vibration frequency of the vibration plate 401 and the spring feeding speed can help engineers or technicians accurately calculate the spring feeding speed under a specific vibration frequency and moving distance, which is of great significance for optimizing the feeding process and improving production efficiency.

[0072] By adjusting the vibration frequency f and the moving distance d, the material supply rate can be controlled to adapt to different production needs and rhythms;

[0073] The relationship between the conveyor belt speed and the motor speed is calculated by the following formula:

[0074] vband = π*D*N;

[0075] Wherein the speed of the cover conveying motor 204 is N (rpm), the diameter of the cover conveying rotating shaft 202 is D shaft, and the linear speed of the conveying belt is v belt;

[0076] If you need to convert the linear velocity to speed per second (mm / s), you need to divide by 60:

[0077] The relationship between the conveyor belt speed and the motor speed: The conveyor belt speed can be precisely controlled by controlling the motor speed N and the diameter of the conveyor shaft D_{shaft}. This is crucial to ensure the synchronization and accuracy of material transportation during the production process.

[0078] Converting line speed from per minute to per second helps to more finely adjust and monitor the conveying speed to ensure smooth operation of the production line;

[0079] The relationship between pressure and force in a pneumatic system is calculated using the following formula:

[0080] F=P*A;

[0081] Where the air pressure of the pneumatic system is P (Pa), the cross-sectional area of ​​the cylinder is A (m²), then the force generated by the cylinder is F (N);

[0082] Here P can be obtained by the working pressure of the pneumatic cylinder, and A is the area of ​​the cylinder piston, which is usually calculated from the diameter of the cylinder;

[0083] Through the relationship between pressure and force in the pneumatic system, the force F generated by the cylinder can be calculated directly from the air pressure P and the cylinder cross-sectional area A. This is very critical for debugging the pneumatic system to ensure that the force output by the cylinder meets the working requirements.
