Abstract

The utility model discloses a rolling lateral slicer device which is installed between a big film roll and a hollow steel core rolling roller. The rolling lateral slicer device comprises a cutting arm and a lateral slicer, wherein the cutting arm is provided with the lateral slicer; the blade of the lateral slicer is set into a crescent shape. The rolling lateral slicer device has small lateral cutting resistance, so that the cut film is not blocked by fragments cut by a lateral-slicing rotary tool bit because the sharp tool bit is operated at a high lateral speed so as to solve the problem of various production faults, and the phenomena of breaking film and halt because of a lateral slicer problem in the rolling and roll changing processes are avoided.

Description

A kind of rolling revolving knife device

Technical field

The utility model relates to a kind of rolling revolving knife device.

Background technology

In the bidirectional stretching plastic film flow production line, this link of rolling is last key link behind the film forming, and it means that premium-quality product is about to off-line and walks processing enterprise downstream.And full automaticity change of lap process is the procedure auto-control process that rolling station equipment station is many, the position is the most accurate, running is the sensitiveest.Manufacturing line is supporting is installed in disc type between big film volume and the empty steel core wind-up roll and revolves cutter and can occur following problem through regular meeting during in change of lap cutting automatically: the one, it is stuck to arrive preseting length or the rupture of membranes of the starting shooting fragment film that cutterhead is downcut when needing change of lap of starting shooting again in manufacturing line rolling film length, cause cutting can't accomplish produce the traction rupture of membranes, serious having to shut down and handled; The 2nd, the dise knife that in the change of lap process, rotates equally is when laterally high-speed cruising is at the face that floats; Because disk diameter is limited; If floating, face surpasses its rotating diameter; This moment, film can't cut, and the change of lap failure has only the film of watching between two wind-up rolls, to tear, and final rupture of membranes or shutdown are handled.

The utility model content

The purpose of the utility model is to provide a kind of rolling revolving knife device; The utility model transverse cuts resistance is little; Sharp cutter head is under horizontal high-speed cruising; The film of cutting does not brokenly block as the fragment that the crosscut rotary cutter downcuts, thereby has solved several big production failure problems, has stopped the revolving knife problem causes in rolling change of lap process rupture of membranes and shutdown phenomenon.

In order to achieve the above object, the technical scheme of the utility model is:

A kind of rolling revolving knife device is installed between big film volume and the empty steel core wind-up roll; Described rolling revolving knife device comprises cutting arm and revolving knife; Described cutting arm is divided into control position and two kinds of locations of off-position; Revolving knife is installed on the cutting arm; The blade part of described revolving knife is arranged to falcate.

The beneficial effect of the utility model is: the device of the utility model is because not rotation; Do not control the heavy burden such as slip groove and motor of its driving yet; The transverse cuts resistance is little, and sharp cutter head is under horizontal high-speed cruising, and the film of cutting does not brokenly block as the fragment that the crosscut rotary cutter downcuts; Thereby solved several big production failure problems, stopped the revolving knife problem causes in rolling change of lap process rupture of membranes and shutdown phenomenon.

The specific embodiment

Embodiment 1

A kind of rolling revolving knife device of present embodiment is installed between big film volume 1 and the empty steel core wind-up roll 2; Described rolling revolving knife device comprises cutting arm 5 and revolving knife 4; Described cutting arm is divided into control position and two kinds of locations of off-position; That as shown in Figure 1 is the control position A of cutting arm 5, and cutting arm 5 off-position B are equipped with revolving knife 4 on the described cutting arm 5; The blade part 7 of described revolving knife 4 is arranged to falcate.

As shown in Figure 1, when rolling arrives change of lap length, big film volume 1 and empty steel core wind-up roll 2 turnup in-positions; When touch roll 3 slowly was close to sky steel core wind-up roll 2, cutting arm 5 moved down into working position by instruction, moves on to off-position B on the cutting arm 5; At this moment, the falcate blade 7 on the revolving knife of installing on the cutting arm 54 is between the big film volume 1 and empty steel core wind-up roll 2 like Fig. 1, and at this moment cutting arm gets into control position A; The film 8 that falcate blade 7 is passed want crosscut; Because not rotation, do not control the heavy burdens such as slip groove and motor of its driving yet, the transverse cuts resistance is little; Sharp cutter head is under horizontal high-speed cruising; The film of cutting brokenly 8 does not block as the fragment that the crosscut rotary cutter downcuts, thereby has solved several big production failure problems, has stopped the revolving knife problem causes in rolling change of lap process rupture of membranes and shutdown phenomenon! After cutting is accomplished, turn back to off-position B by instruction with the cutting arm 5 of revolving knife 4.

The device of present embodiment is because not rotation; Do not control the heavy burden such as slip groove and motor of its driving yet; The transverse cuts resistance is little, and sharp cutter head is under horizontal high-speed cruising, and the film of cutting does not brokenly block as the fragment that the crosscut rotary cutter downcuts; Thereby solved several big production failure problems, stopped the revolving knife problem causes in rolling change of lap process rupture of membranes and shutdown phenomenon.

Claims
