By setting a preset first pressure difference, a preset second pressure difference, a preset first speed adjustment coefficient, and a preset second speed adjustment coefficient, the central control module uses the corresponding speed adjustment coefficient to adjust the conveying motor speed according to the pressure difference, thereby improving the qualified rate of the molded chess pieces and further improving the production efficiency and production quality of the chess pieces.

[0045] Furthermore, the chess piece production method described in the present invention sets a preset allowable roughness, and the central control module uses a roughness sensor to determine the smoothness of the chess piece. If the smoothness of the chess piece surface is lower than the allowable range, the running smoothness will be reduced. By setting a preset first roughness difference, a preset second roughness difference, a preset third speed adjustment coefficient, and a preset fourth speed adjustment coefficient, the central control module uses the corresponding speed adjustment coefficient according to the roughness difference to perform a secondary adjustment on the conveying motor speed, thereby reducing the surface roughness of the chess piece and further improving the production efficiency and production quality of the chess piece.

If the conveying motor rotates too slowly, the chess pieces will be stacked and squeezed, causing the average angular defect length of the molded chess pieces to exceed the allowable range. By setting a preset first pressure difference, a preset second pressure difference, a preset first speed adjustment coefficient, and a preset second speed adjustment coefficient, the central control module adjusts the conveying motor speed using the corresponding speed adjustment coefficient according to the pressure difference, thereby improving the qualification rate of the molded chess pieces and further improving the production efficiency and production quality of the chess pieces.

[0090] Please continue reading Figure 1 As shown, the central control module determines whether the smoothness of chess pieces is within the allowable range according to the average roughness of several chess pieces within a unit period using two determination methods, wherein:

[0091] The first degree determination method is that the central control module determines whether the smoothness of the chess piece is within an allowable range under a preset first roughness condition;

[0092] The second degree determination method is that the central control module determines that the smoothness of the chess piece exceeds the allowable range under a preset second roughness condition, and adjusts the conveying motor speed to the second corresponding speed by calculating the difference between the average roughness of the chess piece and the preset allowable roughness;

[0096]

[0097] Among them, Re is the average roughness of the chess piece, Re i is the roughness of the i-th chess piece, and n is a natural number greater than or equal to 1.

[0098] The central control module determines three secondary adjustment methods for the conveying motor speed according to the difference between the average roughness of the chess piece and the preset allowable roughness, wherein:

[0099] The first secondary adjustment method is that the central control module adjusts the speed of the conveying motor to the corresponding speed under the preset first roughness difference condition;

[0100] The second secondary adjustment method is that the central control module adjusts the conveying motor speed to the third speed using a preset fourth speed adjustment coefficient under a preset second roughness difference condition;

[0101] The third secondary adjustment method is that the central control module adjusts the conveying motor speed to a fourth speed using a preset third speed adjustment coefficient under a preset third roughness difference condition;
