Paperboard rolling machine

Abstract

The invention discloses a paperboard rolling machine and belongs to the field of packaging machines. The paperboard rolling machine comprises a machine base, a connection plate and a pressure supply device. The connection plate is connected with one end of the pressure supply device to be suspended above the machine base. A pressing plate is arranged between the connection plate and the machine base and connected with the connection plate. The lower surface of the connection plate is provided with upper bumper blocks. The portions, corresponding to the upper bumper blocks, on the machine base are provided with lower bumper blocks. The vertical heights of the upper bumper blocks and the lower bumper blocks can be adjusted. The sum of the heights of the upper bumper blocks and the lower bumper blocks is slightly larger than the height between the lower surface of the connection plate and the lower surface of the pressing plate. According to the paperboard rolling machine, the upper bumper blocks make contact with the lower bumper blocks before the pressing plate is combined with a paperboard, the reaction force borne by the pressing plate is relieved, and the pressing plate is protected effectively; meanwhile, the heights of the upper dumper blocks and the lower dumper blocks can be adjusted to meet the rolling requirements of paperboards of different specifications; and multiple springs are arranged between the pressing plate and the connection plate, and the buffering effect can be further provided to protect the pressing plate.

Description

technical field [0001] The invention relates to a cardboard rolling machine, in particular to a cardboard rolling machine capable of preventing pressure plate impact damage, belonging to the field of packaging machinery. Background technique [0002] The rolling forming of cardboard is a necessary process in the production process of cardboard. Usually, rollers are used for rolling, and the cardboard is rolled and formed by the weight of the roller itself. However, this kind of roller has only one weight, which is suitable for all pressing plates. It is a kind of pressure, which will cause uneven rolling of the cardboard. In the prior art, the upper and lower platens are used for rolling, and the air pump provides different rolling pressures to meet the rolling needs of different cardboards; but it cannot be combined with the cardboard during the downward running of the platen The reaction force generated during the operation is effectively buffered, causing the pressure pl...
