Cutter device for flexible pipe for medical purpose

Abstract

The present invention relates to a medical hose cutting device, which comprises a knife holder assembly, an anvil wheel assembly, an air cylinder and a foot plate and so on. A full-cutting blade and a semi-cutting blade are arranged on the rotary knife head of the knife holder assembly. A servo motor is fixed and arranged on a linear bearing by a motor bracket. The linear bearing is covered and arranged on a mandrel which is supported by and arranged on the foot plate. An anvil wheel is fixed on an anvil wheel shaft and is driven to whirl by the servo motor and through a synchronous belt. Theair cylinder is fixed on the foot plate by a crow foot. The knife holder assembly is driven by the air cylinder and moves from left to right, which realizes the work switch between the full-cutting blade and the semi-cutting blade. The rotary linear speed of the rotary knife head and a cutter is equal to the transmission linear speed of the hose. At the cutting moment, the cutter and the hose arerelatively static, which can realize online dynamic cutting. The invention is of simple and reasonable structure and convenient to be operated and used, which significantly improves the productivity effect. The full-cutting and semi-cutting of the hose can be completed in the state that the hose transport goes on and the cutting dimension accuracy is high.

Description

Technical field [0001] The invention relates to a hose cutting device, in particular to a medical hose cutting device. Background technique [0002] We know that the traditional PVC medical hose cutting methods are all manual operations, which have poor cutting size accuracy, low work efficiency and high material waste. Some use an automatic shearing machine to complete the cutting. For example, the patent 022922083 discloses a fully automatic PVC medical hose shearing machine, which is driven by a motor to drive a driving roller to drive a driven roller to make the PVC hose on the supporting guide frame. It runs along the gap between the guide rails. The guide rail is equipped with a lower knife slot and a cutter is installed at the corresponding position. The active roller drive and shear drive of the cutter, as well as the operation of ruler and counting, are all controlled and operated by the photoelectric switch. The conveying of the hose is at a standstill when cutting, an...
