Case board paper perforating machine

Abstract

A case board paper perforating machine comprises a support. Conveying belt rollers are arranged at the two ends of the support, conveying belts are arranged on the conveying belt rollers in a tightening mode, a clearance is reserved between the conveying belts, a bottom cutter is fixedly arranged in the clearance, a needle knife is arranged over the bottom cutter, the needle knife and the bottom cutter are closely attached when the needle knife and the bottom cutter are in butt joint and contact, the upper end of the needle knife is fixed with a telescopic rod, and the telescopic rod is fixedly arranged on an arch-shaped frame supported above the conveying belts. The top end of the needle knife is fixedly arranged on a fixed boss ring, a forested layer is arranged on the inner side of the fixed boss ring, and a fixed pipe is arranged at the upper end of a fixed boss. The needle knife is formed by fixing more than two narrow blades in the fixed boss ring, and the width of the narrow blades is matched with the clearance between the adjacent narrow blades. When the telescopic rod stretches to the longest distance, the needle knife surrounds the bottom cutter, and the cutter edge of the bottom cutter is in break-in with the forested layer. Through the case board paper perforating machine, the pressing prints of holes can be manufactured on case board paper mechanically and continuously, the case board paper in the holes exists, and the case board paper in the holes can be selected to be removed or retained according to use condition needs.

Description

technical field [0001] The invention relates to a cardboard punching machine, which is a device for punching holes on cardboard by needles, and belongs to the field of machinery. Background technique [0002] Carton is a commonly used tool for holding items in the process of transportation. In order to facilitate the handling of the carton, it is usually necessary to have a hole on the side of the carton that can be inserted into the finger. Such a hole is usually formed on the carton. will be made before. Traditionally, to make such a hole, you need to press the cardboard paper on the punching edge and hit it with a wooden hammer. The cardboard paper is cut off by the punching edge, and the punching edge can be formed into a corresponding hole according to the shape and size of the hole. Shape and specifications, the hole made in this way is completely hollowed out. After being made into a carton, the hole is directly connected to the outside. When using a carton that doe...

Problems solved by technology

Traditionally, to make such a hole, you need to press the cardboard paper on the punching edge and hit it with a wooden hammer. The cardboard paper is cut off by the punching edge, and the punching edge can be formed into a corresponding hole according to the shape and size of the hole. Shape and specifications, the hole made in this way is completely hollowed out. After being made into a carton, the hole is directly connected to the outside. When using a carton that does not need to be transported, or for placing items that need to be sealed and stored, the hole Existence affects the use of cartons instead, and the traditional method of making holes is low in efficiency and labor-intensive
