Background technology
BOPP is the abbreviation of " Biaxially Oriented Polypropylene ", i.e. bidirectional stretching polypropylene film.Its production is that at first the melt of macromolecule polypropylene is made sheet material or thick film by long and narrow head, then in the stretching-machine of special use, under the speed of certain temperature and setting, simultaneously or the stretching carried out on vertical both direction (vertically, laterally) of substep, and the film of making through suitable cooling or heat treatment or special processing (as corona, coating etc.).
Vertical machine drawing is in the BOPP production line, film to be carried out the machine of longitudinal stretching, the for example disclosed vertical machine drawing of Chinese patent literature [CN102285107A], comprise vertical machine drawing body, vertical machine drawing body comprises drive end wallboard, Partner wallboard and bearing assembly, roller is installed between the drive end wallboard of indulging the machine drawing body and Partner wallboard is, be positioned at each roller of roller system on the axle of Partner wallboard inboard a cover manual system is installed, the roller outside vertical machine drawing body drive end wallboard is on each roll shaft of a side, the set of gears transmission system to be installed.Should vertical machine drawing realize the longitudinal stretching of film by roller, making film remain at relatively high temperature according to properties of materials needs when stretching could stretch smoothly, because this vertical machine drawing is open, therefore dust is easy to just be attached on film surface, the quality of the material of this moment is relatively soft, dust may be combined with film, affects the physical characteristic of film, makes the quality of film reduce.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed the dust guard of vertical machine drawing in a kind of BOPP film line, and this dust guard has can prevent that dust from entering the characteristics in vertical machine drawing.
The purpose of this utility model can realize by following technical proposal: the dust guard of vertical machine drawing in a kind of BOPP film line, described vertical machine drawing comprises frame, it is characterized in that, this dust guard is fixed on frame, comprise shell and some dust-catching boards, described shell is fixed on frame and with the frame parcel, described dust-catching board is fixed on the medial surface of shell, and described dust-catching board is connected with electrostatic generator.
Shell wraps the minimizing dust with frame and enters in shell, the dust that the while dust-catching board can will enter in housing adsorbs, make the BOPP film complete in dustless environment and stretch and winding process, guarantee that the BOPP film can not be subject to contamination by dust in stretching, improves the quality of product; Electrostatic generator can make and produce static on dust-catching board, can control dust suction by the switch electrostatic generator, and by static, that the dust adsorption structure is simple, noise is little, can not have influence on the production of BOPP film.
Indulge in the dust guard of machine drawing in above-mentioned BOPP film line, the rectangular cylinder of described shell, have opening one and opening two, the rectangular frame of described dust-catching board, described dust-catching board are separately fixed at shell and are positioned on the medial surface that opening one and opening two go out.Dust-catching board be fixed on opening once and opening two places can with its absorption before dust enters shell, guarantee the dustfree environment in shell.
In the dust guard of vertical machine drawing, the both ends of the surface of described dust-catching board are fixed with respectively insulation board in above-mentioned BOPP film line, the medial surface projection of the relative dust-catching board of described insulation board.Insulation board can prevent that staff's the dust-catching board that touches from getting an electric shock, and guarantees production safety.
In the dust guard of vertical machine drawing, described insulation board adopts plastic material to make in above-mentioned BOPP film line.
In the dust guard of vertical machine drawing, described dust-catching board adopts ferrous material to make in above-mentioned BOPP film line.
Compared with prior art, in this BOPP film line, the dust guard of vertical machine drawing has the following advantages:
1, will indulge the machine drawing parcel by shell and make vertical machine drawing be semi-closed state, and reduce dust and enter.
2, the opening by dust-catching board being arranged shell once and opening two can with its absorption before dust enters shell, guarantee the dustfree environment in shell.
3, by static, that the dust adsorption structure is simple, noise is little, can not have influence on the production of BOPP film.
