The utility model relates to a kind of mud bar cutting machine, especially can cut the mud bar in advancing on a moving belt.
The open a kind of synchronous mud bar cutting machine of patent CN202763996U, comprises frame, frame is provided with velocity sensor, with the mud bar conveying mechanism of the extruded velocity synchronous transport mud bar of mud bar and cutting mechanism, and automatic control system; Mud bar conveying mechanism comprises mud bar conveying motor, mud bar conveying reductor and Belt Conveying assembly; Cutting mechanism comprises four root posts being laid in frame top, the steel wire rack being arranged on the cutting knife on column and being connected to above cutting knife, and mud bar cutting motor and mud bar cutting speed reducer, the frame top being positioned at the space that four root posts surround is provided with cutting bed, the bottom of cutting bed is provided with slide block, steel wire rack is connected with many cutting steel wires, mud bar cutting speed reducer is connected with frame and cutting knife by link assembly.In this patent formula, action drives by the mode of motor by speed change and connecting rod, and use mechanism complicated, continuity of movement is poor, the defect that mismatch error is large.How to improve the deficiency that prior art exists, design the scheme that a kind of structure is simple, reliable, namely become the object of the utility model research.
Summary of the invention:
The purpose of this utility model is that a kind of cutting mechanism of design moves back and forth, cutting action is by the mud bar cutting machine of advancing of air cylinder driven.
Technical solutions of the utility model are achieved in that one is advanced mud bar cutting machine, comprise frame, conveyer belt, cutting mechanism and controlling organization, it is characterized in that conveyer belt feed end is arranged with a movable stand, this movable stand is arranged on pair of frame slide rail, be provided with a reciprocating air cylinder between itself and frame, drive movable stand to move back and forth on pair of frame slide rail by this reciprocating air cylinder; Described movable stand rear portion is fixed with a pair guide shaft, guide shaft be arranged in be fixed on frame both sides pulley assembly on, can do along pulley assembly the reciprocating motion being parallel to direction of belt travel; Described guide shaft is positioned with induction frame, this induction frame and movable stand spacing adjustable, and on this induction frame, sensor is installed; Described cutting mechanism comprises steel wire, framework, tensioning wheels and stretcher, and described steel wire one end system is solid on framework, and the other end is through being be located on stretcher after tensioning wheels, and stretcher is fixed on framework; Described cutting mechanism is slidably mounted on the guide rail of movable stand by framework, is provided with cutting cylinder between described movable stand and framework, is moved back and forth along described guide rail by cutting air cylinder driven framework; Described frame is provided with limit assembly in described guide shaft or movable stand range of movement; Described limit assembly, sensor, reciprocating air cylinder and the action of cutting cylinder are controlled by controlling organization.
Described limit assembly is arranged in the frame of described guide shaft rear end.
The utility model adopts air cylinder driven cutting mechanism and cutting action, and structure is more reasonable and simple; Moreover, coordinate the linear motion rail of slide rail, guide rail and guide shaft, reach higher running precision; Have the advantages that registration, cross-cutting fault do not tilt and pug head is complete.
