Automatic thin knife longitudinal cutting device for paperboard

Abstract

The invention discloses an automatic thin knife longitudinal cutting device for paperboard. The device comprises a rack, wherein conveying rollers are rotatably arranged at two ends of the rack, a conveying belt is rotatably mounted on the surfaces of the conveying rollers, a mounting plate is fixedly mounted at one end of the rack, fixing plates are fixedly connected to the surface of the other side of the mounting plate, an inclined connecting plate is hinged to the surface of one side of each fixing plate through a hinge seat, the other end of each inclined connecting plate is fixedly connected with a mounting frame, the side surface of each mounting frame is rotatably provided with a longitudinal cutter, the shaft end of each longitudinal cutter is fixedly provided with a driven belt wheel, the surface of the other side of each mounting frame is fixedly connected with connecting springs, the other ends of the connecting springs are fixedly provided with auxiliary pressing plates, and the side surfaces of the auxiliary pressing plates are provided with a strip cutting groove. In this way, the convenience and stability of use can be greatly improved, and the safety and high efficiency can be ensured.

Description

technical field [0001] The invention relates to the field of slitting devices, in particular to an automatic thin knife slitting device for cardboard. Background technique [0002] In the production process of corrugated paper, it needs to be cut and divided, which requires the use of a knife slitting device, which can be cut longitudinally along the rolled cardboard and divided into different widths for use. [0003] However, in the existing slitting devices, most of the slitting knives are directly installed on the main shaft, and then driven up and down to connect, so that not only is it not conducive to guide and compress the cardboard when it is used again, it is easy to shift and misplace and affect the cutting quality. Up and down adjustment needs to drive the frame and the main shaft to move synchronously. The driving weight is heavy, which is not conducive to ensuring the stability of the main shaft. Moreover, all slitting knives need to be adjusted synchronously, w...

[0003] However, in the existing slitting devices, most of the slitting knives are directly installed on the main shaft, and then driven up and down to connect, so that not only is it not conducive to guide and compress the cardboard when it is used again, it is easy to shift and misplace and affect the cutting quality. The up and down adjustment needs to drive the frame and the main shaft to move synchronously. The driving weight is heavy, which is not conducive to ensuring the stability of the main shaft. Moreover, all slitting knives need to be adjusted synchronously, which is poor in practicability. A new slitting device needs to be proposed
