Description

Technical Field

[0001] The utility model specifically relates to the technical field of cardboard punching, in particular to a cardboard punching device. Background Art

[0002] After the cardboard is produced and processed, it needs to be punched on its surface to facilitate the transportation of the carton after the packaging is completed. At the same time, the punching of the cardboard is convenient for the heat dissipation of the packaged objects.

[0003] However, the conventional punching device directly uses a pressing method when punching, which easily causes burrs to appear at the hole position of the cardboard during punching, making the surface of the support plate unsightly. In addition, the pressing method may also cause damage to the edge position of the hole position of the cardboard during processing.

[0004] After searching, Chinese patent publication number CN201811377230.4 discloses a punching device for packaging cardboard; it includes a bottom plate, an H-shaped bracket, a support plate, a vertical plate and a support frame are respectively arranged on the bottom plate, U-shaped plates are symmetrically distributed on the support frame, pressure rollers are movably connected between the U-shaped plates, a conveying roller group and a material receiving trough are arranged between the U-shaped plates, a driving motor is arranged on the vertical plate, the driving motor is connected to a turntable, a transmission plate is eccentrically connected to the turntable, a mounting plate is slidably connected to the vertical plate, a swing rod is arranged between the mounting plate and the transmission plate, an L-shaped fixing block is arranged on the mounting plate, a punch is arranged on the L-shaped fixing block, a transmission wheel is movably connected to the H-shaped bracket, a material receiving motor is arranged on the support plate, the material receiving motor is connected to the driving plate, a transmission pin is arranged on the driving plate, and a stop groove is circumferentially distributed on the outer circumference of the transmission wheel, and the stop groove corresponds to the transmission pin;

[0005] The processing in the above patent can achieve continuous punching during processing, but when the punch contacts the support plate, it can only penetrate the support plate, and cannot effectively cut the paperboard material at the position where the support plate needs to be opened. The structure in the above patent cannot effectively separate the paperboard material at the opening from the paperboard during operation, and the structure in the above patent will cause a relatively rough situation at the bottom of the paperboard during processing, affecting the overall aesthetics of the paperboard;

[0006] In view of the above situation, we provide a cardboard punching device. In this device, a flywheel is driven to rotate by a driving motor, so that the flywheel drives the rotating shaft to drive the eccentric wheel to rotate. An upper punch is detachably installed at the bottom of the eccentric wheel. Through the rotation of the eccentric wheel, the groove opened inside the hard plate of the upper punch is effectively overlapped with the steel ring on the lower punch, so that the cardboard material at the place where the hole needs to be opened is effectively separated from the cardboard; through the rotation of the eccentric wheel, the continuous working effect is effectively achieved.
