Description

Small rough edge comb

Technical Field

The utility model belongs to the technical field of computer rip cutting trimmer spare part, especially, relate to a little deckle edge comb.

Background

The corrugated board is mainly cut by a computer longitudinal cutting and trimming machine, so that the production efficiency is high, and the cutting precision is high. The cutting quality of the corrugated board by the computer longitudinal cutting edge trimmer is mainly determined by a knife anvil matched with a cutter wheel, the more fully the knife anvil supports the corrugated board, the smaller the burr of the corrugated board after cutting, and the smaller the trimming width of the corrugated board. At present, knife anvils of a computer longitudinal cutting edge trimmer mainly comprise a roller type knife anvil and a comb type knife anvil, but have the following defects:

roller type knife anvil: the roller type knife anvil consists of a roller shaft and about 1500 epoxy resin sheets sleeved on the roller shaft, the whole weight of the roller type knife anvil reaches 400 jin and 500 jin, so that the roller type knife anvil is very inconvenient to maintain and replace and extremely expensive in price, the market price of one group of roller type knife anvil is about 2 ten thousand to 3 ten thousand, and the price of only the epoxy resin sheets is 8 yuan/1500 yuan/12000 yuan; after the roller type knife anvil is used, the epoxy resin sheet can be abraded by the cutter wheel to form burrs, pits and the like, and the cut waste paper edge is easy to roll on the epoxy resin sheet, so that the daily maintenance is very difficult; the existing computer longitudinal cutting edge trimmer using the roller type knife anvil can achieve the edge trimming width of about 2 centimeters due to the sufficient jacking degree, the waste of corrugated boards is large, the edge trimming width is the width of cutting off the rough edges of the corrugated boards, and the smaller the edge trimming width is, the smaller the waste is.

Comb-type knife anvil: for example, the fiber knife felt of a slitter of a national patent (patent No. 2019207654442) comprises a knife holder and a fiber blade with high elasticity, wherein a plurality of fiber blades are uniformly arranged on the knife holder along the vertical direction. The fiber blades are made of elastic fibers, so that the elastic restoring force is high, the friction resistance is high, the knife holder is arranged on the knife bracket, and the cutting can be performed after the tangent plane of the cutter faces the gap between the two fiber blades. The cutting knife wheel is matched with the cutting knife wheel, although the cutting quality is better, in the cutting process, the cutting knife wheel extrudes the fiber blades, the fiber blades on two sides of the cutting knife wheel are elastically bent towards two sides, the distance between the two fiber blades on the front side of the cutting knife wheel is increased, the cutting knife wheel has downward acting force on the cutting position and the position to be cut of the corrugated board when the corrugated board is cut, the increase of the distance weakens the jacking support on the cutting position and the position to be cut of the corrugated board, and finally the lower side edge of the corrugated board after cutting generates larger burrs and has the same larger trimming width.
