Anti-blocking cutter for paperboard drilling

Abstract

An anti-blocking cutter for paperboard drilling comprises a top plate, a connecting piece is fixedly connected to the circle center of the top plate, cutter cylinders are evenly arranged at the bottom of the top plate and located on the periphery of the connecting piece, fixing rods are arranged in the cutter cylinders, the interiors of the cutter cylinders are dredged, a stabilizing plate is arranged between the fixing rods and the connecting piece to limit and stabilize the cutter cylinders, an exhaust mechanism is arranged between the top plate and the stabilizing plate, a retractable air cylinder is arranged between the stabilizing plate and the top plate, and a limiting assembly is arranged on the surface of the stabilizing plate to limit and stabilize the overall stability of a cutter. Through cooperation of the cutter cylinders and the fixing rods, the fixing rods can clean the interior of the cutter cylinders after drilling of the cutter cylinders, paper scraps entering the interior of the cutter cylinders are discharged, in addition, the end openings of the fixing rods are located on the outer side of the cutter cylinders through relative movement between the fixing rods and the cutter cylinders, and therefore the cutter cylinders are not affected by the paperboard scraps.

Description

technical field [0001] The invention belongs to the technical field of cardboard processing, in particular to an anti-clogging cutter for drilling holes in cardboard. Background technique [0002] Cardboard is usually made of various plant fibers, and non-plant fibers are also added, which are made on a cardboard machine. Some special cardboards are also mixed with animal fibers such as wool or mineral fibers such as asbestos. Cardboard can be seen everywhere in daily life, and the use of cardboard is also diverse. In some cardboard processing, in order to meet the needs of actual use, it is necessary to drill the formed cardboard to meet the actual use. [0003] However, when drilling cardboard, since the material of the cardboard itself is light and fragile, if the internal solid tool can be directly used to achieve the drilling operation, it is very likely that the drilled hole of the cardboard will be cracked, resulting in the failure of the cardboard to work properly. ...

AI Technical Summary

Problems solved by technology

[0003] However, when drilling cardboard, since the material of the cardboard itself is light and fragile, if the internal solid tool can be directly used to achieve the drilling operation, it is very likely that the drilled hole of the cardboard will be cracked, resulting in the cardboard not being able to work normally. Used or even scrapped, if a hollow tool is used, although it can reduce the possibility of cracking the cardboard drilling hole, it can also meet the drilling requirements of the cardboard, but the hollow design will make it easy to block the cardboard debris inside the tool. The inside is blocked by cardboard debris, and the drilling effect will be greatly reduced. In addition, because the material of the cardboard itself is light, it is difficult to discharge it when it enters the cutter. If too many debris enters the cutter, it is difficult to break the cardboard. Chips escape from the inside of the tool, requiring a hollow tool that is less prone to clogging
