The invention discloses a pneumatic flat pressing
machine for sticking a
carton box and belongs to the field of
carton box formation machines. The pneumatic flat pressing
machine comprises a pneumatic pressing
bed, a first support, a second support, a cross beam and a flat pressing mechanism, wherein the first support and the second support are arranged vertical to the working plane of the pneumatic pressing
bed, the cross beam is fixedly connected between the first support and the second support, and the flat pressing mechanism is arranged on the cross beam; the flat pressing mechanism comprises an air cylinder, a mounting plate, a self-adaption inclining device, a press plate and a pneumatic
system; the air cylinder is fixedly arranged on the mounting plate and is connected with the cross beam through the self-adaption inclining device; a
piston rod of the air cylinder is connected with the press plate through the cross beam; the air cylinder is connected with the pneumatic
system and controls the lifting of the air cylinder through a control valve arranged on the outer wall of the pneumatic pressing
bed. According to the pneumatic flat pressing
machine disclosed by the invention, the problem that the pressure of a sticking part of the
carton box is uneven is modified; the flatly pressed carton box is firm in sticking and is flat; the position of the flat pressing mechanism is adjustable, and the press plate is rotatable, so that the use of the flat pressing machine is convenient, the applicability of the flat pressing machine is improved, the structure is simple, the operation is convenient, the cost is low, and the use effect is remarkable.
