Description

Single cutting structure

Technical Field

The utility model relates to a tailor the equipment, especially relate to a cut sola structure of cutting paper.

Background

The paper needs to be cut and separated into one piece after being printed or processed by other processes, but the existing cutting equipment has a complex structure and higher manufacturing and maintenance cost; and the cutting precision is difficult to ensure by the cutting equipment with poor quality.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a simple structure and work are quick, accurate cuts out sola structure to simplify equipment structure and improve the machining precision.

The utility model discloses a sheet cutting structure, which comprises a fixed knife, a movable knife, a motor and a fixed shaft, wherein the fixed knife is fixedly arranged, the movable knife is movably arranged, the motor outputs power, and the fixed shaft rotates around a fixed axis; the cutting edges of the fixed knife and the movable knife are oppositely arranged, the output end of the motor is provided with a cam, the axis directions of the cam and the fixed shaft are parallel to the arrangement direction of the movable knife, the two ends of the fixed shaft are respectively provided with a driving rotating plate and a driven rotating plate, the cam and the driving rotating plate and the one end of the movable knife are connected through a connecting rod assembly, the other end of the movable knife and the driven rotating plate are respectively connected through a connecting rod assembly, and the end part of each connecting rod assembly is respectively hinged with the cam, the driving rotating plate or the driven rotating plate.

In the single-sheet cutting structure of the utility model, the fixed knife is fixedly arranged, and the movable knife opposite to the cutting edge can move towards or back to the fixed knife; the motor drives the cam to rotate, the cam drives the driving rotating plate and the fixed shaft to rotate through the connecting rod assembly, and when the fixed shaft rotates, the driving rotating plate and the driven rotating plate on the cam drive the two ends of the movable cutter to move through the connecting rod assembly connected to the driving rotating plate and the driven rotating plate respectively, so that the movable cutter is in contact with the fixed cutter to cut paper, or the movable cutter leaves the fixed cutter to allow the paper to pass through. The single cutting sheet has a simple structure, but works accurately, stably and quickly, can effectively simplify the structural complexity of equipment, simultaneously improves the processing precision and the working efficiency, and ensures the cutting quality of paper.

Detailed Description

A single-sheet cutting structure comprises a fixed knife 1, a movable knife 2, a motor 3 and a fixed shaft 4, wherein the fixed knife 1 is fixedly arranged, the movable knife 2 is movably arranged, the motor is used for outputting power, and the fixed shaft rotates around a fixed axis; the cutting edges of the fixed knife and the movable knife are oppositely arranged, the output end of the motor is provided with a cam 5, the axis directions of the cam and the fixed shaft are parallel to the arrangement direction of the movable knife, the two ends of the fixed shaft are respectively provided with a driving rotating plate 6 and a driven rotating plate 7, the cam and the driving rotating plate, the driving rotating plate and one end of the movable knife are connected through a connecting rod assembly 8, and the end part of each connecting rod assembly is hinged with the cam, the driving rotating plate or the driven rotating plate.

As shown in fig. 1, the upper fixed knife is fixed, and the lower movable knife is opposite to the cutting edge of the fixed knife and can move up and down. The motor drives the cam to rotate, the cam drives the driving rotating plate and the fixed shaft to rotate through the connecting rod assembly, and when the fixed shaft rotates, the driving rotating plate and the driven rotating plate on the cam drive the two ends of the movable cutter to move through the connecting rod assembly connected to the driving rotating plate and the driven rotating plate respectively, so that the movable cutter is in contact with the fixed cutter to cut paper, or the movable cutter leaves the fixed cutter to allow the paper to pass through. The single cutting sheet has a simple structure, but works accurately, stably and quickly, can effectively simplify the structural complexity of equipment, simultaneously improves the processing precision and the working efficiency, and ensures the cutting quality of paper.

And the single cutting structure is characterized in that the driving rotating plate 6 and the driven rotating plate 7 are in a long strip shape and are parallel to each other in the arrangement direction, the middle part of the driving rotating plate and one end of the driven rotating plate are respectively arranged at two ends of the fixed shaft 4, one end of the driving rotating plate is opposite to the other end of the driven rotating plate and is respectively connected with the movable knife 2 through the connecting rod assembly 8, and the other end of the driving rotating plate is connected with the cam 5 through another connecting rod assembly. The single-sheet cutting structure can improve the smoothness and accuracy of moving the moving blade, further simplify the structural complexity of the device and improve the working efficiency.

In addition, the connecting rod assembly 8 comprises two connecting rods, one end of each connecting rod is connected with the corresponding connecting rod through a coupler, and the other ends of the two connecting rods are hinged to the cam 5, the driving rotating plate 6 or the driven rotating plate 7, so that a double-connecting-rod structure is formed, the smoothness of linkage is improved through the couplers, and the mounting precision requirement is lowered.
