Collecting cup device of integrated negative pressure system

An integrated negative pressure system collecting cup device comprises a horizontal collecting pipe, a plurality of negative pressure collecting cups which are parallel left and right are installed at the lower end of the collecting pipe through a tray structure, and the lower ends of the negative pressure collecting cups are connected with an external formation mechanism through negative pressure suction nozzles. A first connector is arranged on the left side of the flow guide pipe, a second connector is arranged at the right end of the front side of the flow guide pipe, and a third connector is arranged at the left end of the front side of the flow guide pipe. The integrated negative pressure system collecting cup device is simple in structure and convenient to assemble, concentration is carried out on the basis of an existing design, and the equipment strength and the transportation cost are reduced. Meanwhile, a hose connecting mode is omitted, and common faults such as hose breakage, hose folding and shr
