A knife sharpening reciprocating device and control method for a shredding machine

Abstract

The invention discloses a knife sharpening reciprocating device for a wire cutter, which comprises: a bottom plate, a driving system, a movable pulley transmission system, a knife sharpening device, and a guide rail; the two driving systems are respectively connected to the knife sharpening device through corresponding movable pulley transmission systems, The knife sharpening devices are respectively driven to move in the same direction, so that the knife sharpening devices do reciprocating motion on the guide rail. In addition, the present invention also discloses a method for controlling the knife sharpening device of the shredding machine. The first driving system and the second driving system alternately push the knife sharpening device to move leftward or rightward along the guide rail through the corresponding movable pulley transmission system, so that the grinding The knife device produces reciprocating motion. The present invention adopts the driving mode of linear motion, utilizes the moving pulley mechanism, effectively uses short-stroke driving, realizes large-stroke motion, realizes the reciprocating motion of the sharpening system more effectively and concisely, can effectively save the structural space of the equipment, and simplifies the sharpening device The reciprocating design structure reduces the design cost, is simple and practical, and has great social and economic benefits and application prospects.

Description

technical field [0001] The invention belongs to the field of tobacco cutting equipment, and in particular relates to a knife sharpening reciprocating device and a control method for a shredding machine. Background technique [0002] The cutting machine is an important equipment in the tobacco shredding equipment and a main process equipment in the tobacco processing process. The uniformity and stability of the cut width play a very important role in the moisture balance and filling value of cut tobacco after drying. Most shredders are rolling shreds, and because of their functional requirements, the blades must be kept sharp. To achieve this, the shredding equipment must be equipped with a sharpening system. At present, except for the TOBSPIN wire cutting machine, the wire cutting equipment at home and abroad all use a reciprocating grinding wheel mechanism as the sharpening system of the wire cutting machine, and most of the wire cutting machines use a rotating motor to dr...

Problems solved by technology

At present, except for the TOBSPIN wire cutting machine, the wire cutting equipment at home and abroad all use a reciprocating grinding wheel mechanism as the sharpening system of the wire cutting machine, and most of the wire cutting machines use a rotating motor to drive the screw guide rail to realize the grinding wheel. Most of the reasons for the reciprocating movement instead of linear drive such as cylinders are because the overall use space of the drive components needs to be at least twice the reciprocating travel stroke of the sharpening device in order to truly realize the normal reciprocating movement of the sharpening device. The equipment is not enough Structural space for arranging drive components
