8. The automatic density measuring device for the solid workpieces as claimed in claim 1, wherein a wind screen is arranged on the feeding window.
9. The apparatus of claim 1, wherein a connecting member is disposed between the first and second support modules, and the weight loaded on the second support module is transferred to the second support module through the connecting member, thereby performing weighing and density calculation through the same weighing and measuring module.
10. An automatic density measuring method for a solid workpiece, which is used for the automatic density measuring device for the solid workpiece as claimed in any one of claims 1 to 9, and comprises the following working steps:
s1: placing a solid workpiece to be measured on a bracket of a transportation module;
s2: the transportation module moves to transport the solid workpiece to a dry weighing station;
s3: a first supporting module of the dry-type weighing station supports the solid workpiece, and a weighing measurement module acquires the dry-type weight of the fixed workpiece;
s4: after the dry-type weighing is finished, the transportation module moves again to lift the solid workpiece on the first bearing module and then transports the solid workpiece to the carrying module;
s5: the carrying module is used for carrying the solid workpiece and carrying the solid workpiece to a second supporting module of the wet-type weighing workpiece, the second supporting module is connected with the first supporting module so as to transfer the wet-type weight of the solid workpiece to the first supporting workpiece, the wet-type weight of the solid workpiece is detected by the weighing and measuring module, and the density of the solid workpiece is calculated;
s6: after wet weighing is finished, the carrying module moves again to lift the solid workpiece on the second bearing module and then carries the solid workpiece to the transportation module;
s7: the transport module holds up the solid workpiece and transports the solid workpiece back to the start position.
