Abstract
The invention discloses a cross grain online detection device for a high-transparency polycarbonate sheet. The cross grain online detection device comprises the high-transparency polycarbonate sheet capable of being transmitted on a guide roller, an intensive light source is arranged at one side of the high-transparency polycarbonate sheet, and an image receiving device for receiving images by applying a white-background lighttight large wide-width curtain grained fabric is arranged at a corresponding position at the other side of the high-transparency polycarbonate sheet; and a heat radiating device is arranged on the outer part of the intensive light source. According to the cross grain online detection device for the high-transparency polycarbonate sheet, the cross grain conditions of the transparent sheet can be easily projected on the image receiving device under the action of intensive light, so that the cross grain condition of the transparent sheet is monitored in real time; in addition, the cross grain online detection device not only can be applied to production of the transparent polycarbonate sheet, but also can be applied to cross grain detection of all transparent sheets including transparent polymethyl methacrylate (PMMA) sheets, transparent polyethylene terephthalate (PET) films and the like, and has a wide application range.
Description
Technical field
The present invention relates to a kind of on-line measuring device, especially relate to a kind of high transparency polycarbonate sheet material band on-line measuring device.
Background technology
Polycarbonate sheet is that (Polycarbonate PC) makes through extrusion calendaring by the raw material polycarbonate.Transparent polycarbonate sheets has good light transmittance (transmittance reaches about 90%), excellent shock resistance, high temperature tolerance, good flame-retarding characteristic, combination property such as nontoxic; Can the instead of glass material, be widely used in the aspect such as outer cover material, display panel of the transparent building materials of transparency window material, curtain wall for high rise building, airport and stadiums, lighting.
The polycarbonate sheet of specialty is manufactured device and mainly is made up of extruder, mould, three-roller calendar, traction engine, side cut system, stacking system etc.Servicing unit has quantifying feed system, net exchanging device, Melt Pump etc.The polycarbonate raw material gets into three-roller calendar by mould and carries out cooling and shaping behind the extruder fusion plastification.Because the squeezing action of three rollers, be easy to form in a lateral direction and push lines continuously on the polycarbonate sheet surface, this lines is called the gear line, also claims band.The existence of band can cause transparent polycarbonate sheets in processing technologys such as follow-up printing, to produce surface imperfection, uses thereby influence it, so will alleviate the surperficial band of polycarbonate sheet in process of production as far as possible.
At present, transparent polycarbonate sheets surface band situation is regulated in the variation of technologies such as generally fast through roller temperature, roller, three roller positions, and detection efficiency is not slower, and easy omission.
Summary of the invention
Technical matters to be solved by this invention provides the high high transparency polycarbonate sheet material band on-line measuring device of a kind of detection efficiency.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme.
This high transparency polycarbonate sheet material band on-line measuring device; Comprise and be arranged on the high transparency polycarbonate sheet material that transmits on the deflector roll; One side of said high transparency polycarbonate sheet material is provided with intense light source, and the opposite side correspondence position is provided with the video receiver that the lighttight big wide cut curtain line cloth of utilization white background receives image.
Scrap because of heat is too high in order to prevent that the band on-line measuring device from using for a long time, further, said intense light source outer setting has heat abstractor.
In order to guarantee the serviceable life of intense light source, more further, said intense light source is halogen tungsten lamp, gas-discharge lamp, high-intensity gas discharge lamp, HF lamp without electrodes or light emitting diode.
Different Light is shone the band in the whole clear sheet wide cut scope for ease, further, said intense light source position be provided with one with the parallel track of high transparency polycarbonate sheet material horizontal direction.
Compared with prior art; Usefulness of the present invention is: this high transparency polycarbonate sheet material band on-line measuring device can make the band situation of clear sheet be easy to be projected on the video receiver in the effect of high light, thereby has reached real-time monitoring clear sheet band situation; And this band on-line measuring device not only can be applied to the production of transparent polycarbonate sheets; But also can be applied to comprise that the band of all clear sheets such as transparent polymethacrylate methyl esters (PMMA) sheet material, transparent polyethylene terephthalate (PET) film detects, usable range is wide.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is a kind of high transparency polycarbonate sheet material of the present invention band on-line measuring device structural representation.
Among the figure: 1, image receiving device; 2, high transparency polycarbonate sheet material; 3, deflector roll;
4, intense light source; 5, heat abstractor.
Embodiment:
Describe the present invention below in conjunction with accompanying drawing and embodiment:
A kind of high transparency polycarbonate sheet material band on-line measuring device shown in Figure 1; Comprise the high transparency polycarbonate sheet material 2 that is arranged on the deflector roll 3; One side of said high transparency polycarbonate sheet material 2 is provided with intense light source 4, and the opposite side correspondence position is provided with the video receiver 1 that the lighttight big wide cut curtain line cloth of utilization white background makes to receive image; Prevent that long-term use of on-line measuring device from scrapping because of heat is too high, said intense light source 4 outer setting have heat abstractor 5; Said intense light source 4 is halogen tungsten lamp, gas-discharge lamp, high-intensity gas discharge lamp, HF lamp without electrodes or light emitting diode, thereby has strengthened the serviceable life of intense light source 4; Said intense light source 4 can be pointolite, area source or line source.If the light beam that pointolite sent is difficult to cover whole clear sheet wide cut scope; Can design one with the parallel track of high transparency polycarbonate sheet material 2 horizontal directions; Let pointolite come flyback retrace with certain speed in orbit, in order to shine the band in the whole clear sheet wide cut scope.Because the band pick-up unit that this high transparency polycarbonate sheet material band on-line measuring device is provided comprises intense light source 2 that is used to shine and the video receiver 1 that is used to receive image; So the band situation of clear sheet is easy to be projected on the video receiver 1 in the effect of high light, thereby reached real-time monitoring clear sheet band situation.
This band on-line measuring device not only can be applied to the production of transparent polycarbonate sheets 2, but also can be applied to comprise that the band of all clear sheets such as transparent polymethacrylate methyl esters (PMMA) sheet material, transparent polyethylene terephthalate (PET) film detects.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
