BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a side cutter device for a PVC manufacturing device,

More particularly, the present invention relates to a side cutter apparatus for a take-up reel which is provided on both sides of a roll holder for receiving a take-up roll, And a cutter control section provided on both sides of the cutter apparatus body for cutting the F / V shear wrap at both ends of the take-up roll rotated by the spindle rotation section, and a cutter control section for controlling cutting of the cut edge section, So that it is possible to quickly and easily finish the both ends of the winding roll on which the V-shaped wrap is wound and work can be performed without damaging the branch pipe.

Generally, a PVC wrap is manufactured in a thin film form using PVDF as its main raw material.

The above-mentioned PVS rap is manufactured through a PVS wrap making apparatus comprising an extruder, a stretching machine and a winding machine.

Here, the extruder extrudes the PVC raw material supplied through the hopper into a thin film sheet.

Meanwhile, in the extruding process through the extruder as described above, since the content of air in the raw material must be minimized, the raw material is supplied through the hopper that has been vacuum-processed.

The stretching machine stretches the sheet extruded from the extruder into a thin sheet.

Further, the winding machine winds the sheet drawn by the thinned sheet on the stretching machine in the form of a roll.

However, since the winding rolls wound around the PV yarn produced through the conventional PV manufacturing apparatus as described above are not smoothly finished at both ends thereof, they are cut by manual operation, resulting in poor productivity and clear work There was an issue that did not work.

Therefore, in the present invention, as described above, the winding roll on which the PVR wrap is wound in the manufacture of the PVR through the conventional PVR manufacturing apparatus is not smooth at both ends thereof, And the problem that the productivity is low and the clear work is not done can be solved.

That is, the present invention relates to a cutter apparatus comprising: a roll holder for receiving a take-up roll; a shaft rotating portion provided on both sides of the roll holder for restraining both ends of a branch of the take- And a cutter control section for controlling the cutting of the cut edge portion and the cutter blade portion for cutting the F / V shear wrap at both ends of the take-up roll rotated by the rotary portion.

Accordingly, the present invention provides a side cutter device for a fabricating apparatus, so that both ends of the winding roll wound around the fabric are quickly, easily, and smoothly improved in workability and merchantability.

The roll holder 610 is formed with supporting slopes 611 on both sides thereof so as to form a gap between itself and the outer surface of the wound roll.

The shaft rotating part 620 is provided on both sides of the winding roll and has a branch shaft rotating shaft 621 formed in a cone shape so that an end thereof can be inserted into the center of the winding roll and a branch tube running actuator 621, 622), and a branch pipe driving motor (623) for rotating the branch pipe rotating shaft (621).

The cutting blade portion 630 includes a cutting blade 631 having an outwardly inclined surface and formed in a circular shape, a blade lifting actuator 632 for lifting and moving the cutting blade 631 in two stages, And a blade feed device 633 for moving the blade actuator to be operated in the longitudinal direction of the winding roll.

The blade lifting actuator 632 includes a wrap part cutting pneumatic actuator 632a for raising and lowering the cutting blade 631 so as to form a cutting clearance gap of 2 mm between itself and the paper tube in a partial cutting process at a constant pitch, And a lab-separating cutting hydraulic actuator (632b) for raising and lowering the cutting blade (631) so as to be transversely cut to a depth of 0.5mm into the branch pipe so as to be able to completely separate the wraps of the cutting portion in the cutting process, The cutting hydraulic actuator 632b is formed in the labial cutting pneumatic actuator piston.

The blade feeder 633 feeds the blade at a predetermined pitch during the partial cutting process of the lap and performs a return operation in a state where the cutting blade 631 is inserted so that the blade can be separated from the branch tube of the lap after the lapping and cutting process .

Hereinafter, the operation of the present invention will be described.

The side cutter device 600 includes a side cutter device 600 that cuts both sides of the V-shaped wrap roller manufactured by the P-V seep wrap manufacturing device as described above. The side cutter device 600 includes a cutter device body 601 The roll holder 610 is provided on both sides of the roll holder 610 to accommodate the winding rolls of the winding rolls. A cutting blade portion 630 provided on both sides of the cutter body 601 for cutting the FPC wrap at both ends of the winding roll rotated by the axial rotation portion 620, And a cutter control unit 640 for controlling cutting of the cutter 630,

It is possible to cut quickly, clearly and easily without damaging the branch pipe at both ends of the winding roll.

In addition, since the end portion of the branch pipe rotation shaft 621 is formed in a cone shape, the winding roll placed on the roll holder 610 is spaced apart from the roll holder 610 during the shaking process to prevent interference during the rotation process.

When the blade lifting actuator 632 for lifting and lowering the cutting blade 630 is constructed by the wrap portion cutting pneumatic actuator 632a and the labial separation cutting hydraulic actuator 632b, The cutting blade portion 630 has a gap of 2 mm between the cutting blade portion 630a and the branch pipe so that the branch portion cutting pneumatic actuator 632a is prevented from damaging the branch tube at the time of the partial cutting, The cut blade portion 630 is inserted and cut into the branch pipe by a depth of 0.5 mm by the cutter blade 632b so that the PV seed wrap can be easily separated from the branch pipe.
