Specifically, the support assembly 12 is fixed by the fixed frame 13 that is surrounded by a square, and the positioning protective plate 14 is protruded at both ends of the fixed frame 13 and is perpendicular to the support column 121. The positioning protective plate 14 and the connecting cross bar 122 are connected by a connecting member c, one end of the connecting member c is fixed to the connecting cross bar 122, and the other end is fixed to one surface of the positioning protective plate 14. The connection point between the connecting member c and the connecting cross bar 122 is parallel to the Z-axis slide rail and faces the extension line of the positioning protective plate 14. The connection line with the connection point between the connecting line c and the positioning protective plate 14 is along the surface of the positioning protective plate 14 facing the intersection of the extension line. The extension line, the connecting line and the connecting member c are connected in a triangle. This structural arrangement effectively improves the stability of the support assembly 12. The connecting line c is a steel wire. More specifically, the limit limiting structure b is installed on the support column 121. The limit limiting structure b includes a limit bracket, and a sensor installed on the limit bracket and connected to the control cabinet 5. When it senses that the mesh belt part 3 has risen to a preset position, it sends an instruction to the lifting mechanism 2 to stop driving the mesh belt part 3 to rise.

[0041] The driving structure 21 of the lifting mechanism 2 drives the transmission assembly 22 installed on the two Z-axis slide rails to rise and fall. Specifically, the lifting mechanism 2 includes: a driving structure 21 respectively installed at the lower end of the support assembly 12, a transmission shaft 23 connected to the driving structure 21 and the transmission assembly 22, the transmission assembly 22 is a transmission chain, the transmission chain is wound around the transmission shaft 23 and a horizontal bar installed horizontally at the upper end of the support assembly 21, the driving structure 21 is a servo motor, the driving structure 21 operates according to the received instructions and drives the transmission shaft 23 to rotate, the transmission shaft 23 drives the transmission chain to transmit, further, the reducer on the transmission shaft 23 matches the driving structure 21 to realize the function of raising and lowering the transmission chain. More specifically, the driving structure 21 is arranged between the two support columns 121, and a transmission chain is installed on the Z-axis guide rail of each support column 121, and each transmission chain corresponds to a driving structure 21.
