Udhibiti sahihi wa hali ya joto na kanuni ya nguvu: Aina tofauti za inks za kuchapa zina joto tofauti za kuponya. Kwa mfano, joto la kuponya la wino wa kuchapa msingi wa maji kwa ujumla ni kati ya 80-120 ℃, wakati wino wa kuchapa-msingi wa kutengenezea unaweza kuhitaji joto la juu la karibu 120-160 ℃. Imewekwa na sensorer za joto za hali ya juu na vidhibiti vya joto kwenye mashine ya kuchapa, joto la taa ya joto ya infrared hurekebishwa kwa usahihi kulingana na aina ya wino wa kuchapa unaotumiwa ili kuhakikisha kuwa wino wa kuchapa unaweza kukaushwa haraka na kutibiwa kwa joto la juu, wakati wa kuzuia kubadilika au uharibifu wa muundo uliochapishwa kwa sababu ya joto kali. Chini ya msingi wa kuhakikisha ubora wa uchapishaji, nguvu ya taa ya kupokanzwa inarekebishwa kwa sababu kulingana na sababu kama kasi ya uchapishaji na unene wa wino. Ikiwa kasi ya uchapishaji ni haraka au safu ya wino ni nene, nguvu inaweza kuongezeka ipasavyo ili kuhakikisha kuwa wino ina wakati wa kutosha wa kukamilisha uponyaji katika eneo la joto. Walakini, utunzaji unapaswa kuchukuliwa ili kuzuia nguvu nyingi kusababisha kuongezeka kwa joto na kuathiri athari ya uchapishaji. Kwa mfano, kwa mashine za kuchapa zenye kasi kubwa, nguvu inaweza kuwa karibu 2-3 kW/m²; Kwa mashine za uchapishaji wa kasi ya kawaida, inafaa zaidi kudhibiti nguvu kwa 1-2 kW/m².
Synchronize na kasi inayoendesha ya kanuni ya kulinganisha ya mashine ya kuchapa: kasi inayoendesha ya mashine ya kuchapa na wakati wa joto wa taa ya joto ya infrared inahitaji kuendana kwa karibu. Wakati mashine ya kuchapa inapoenda haraka, inahitajika kuhakikisha kuwa nguvu ya joto ya taa ya kupokanzwa inaweza kuendelea na wimbo wa uchapishaji, ili wino uweze kufikia mahitaji ya kuponya katika muda mfupi unaopita katika eneo la joto. Kwa mfano, wakati kasi inayoendesha ya mashine ya kuchapa ni mita 10-20/dakika, wakati wa joto wa taa ya joto (imedhamiriwa na urefu wa kukimbia na kasi ya mashine ya kuchapa) inapaswa kuwezesha wino kukaushwa kikamilifu na kuponywa ndani ya safu hii ya wakati. Kasi ya kukimbia na vigezo vya taa ya kupokanzwa inaweza kubadilishwa kupitia mfumo wa kudhibiti wa mashine ya kuchapa ili kufikia uboreshaji wa mkakati wa marekebisho mawili.Dynamic: kulingana na ugumu wa muundo wa uchapishaji na sifa za kukausha za wino, kasi ya mashine ya kuchapa na vigezo vya taa ya joto hubadilishwa kwa nguvu. Kwa mifumo rahisi ya kuchapa na inks rahisi-kavu, kasi ya mashine ya kuchapa inaweza kuongezeka ipasavyo; Kwa mifumo ngumu na inks ngumu-kavu, kasi inapaswa kupunguzwa au nguvu ya joto ya taa ya joto inapaswa kuongezeka ili kuhakikisha ubora wa uchapishaji.
Mara kwa mara kudumisha na kusafisha taa ya joto inapokanzwa vumbi na uchafu: wakati wa mchakato wa kuchapa, uchafu kama vile vumbi, nyuzi na matone ya wino yanaweza kujilimbikiza kwenye uso wa taa ya joto. Uchafu huu utaathiri uzalishaji na kupenya kwa mionzi ya infrared na kupunguza ufanisi wa joto. Futa uso wa taa ya kupokanzwa mara kwa mara (kama vile mara moja kwa wiki) na kitambaa laini laini au zana maalum ya kusafisha ili iwe safi. Kwa uchafu wa ukaidi, unaweza kutumia kiasi kidogo cha sabuni kali kuisafisha, lakini kuwa mwangalifu ili kuepusha sabuni kutoka kwa kuingia ndani ya taa ya kupokanzwa ya glasi ya quartz. Kwamba vifaa vya ndani ya balbu ya joto ya halogen (kama vile kipengee cha kutoa infrared) ni mbaya. Kulingana na maisha ya huduma na utendaji halisi wa taa ya kupokanzwa, badilisha sehemu zilizoharibiwa kwa wakati ili kuhakikisha kuwa vitu vya kupokanzwa vya quartz kila wakati huwa na hali nzuri ya kufanya kazi. Kwa ujumla, maisha ya huduma ya vifaa vya joto vya halogen ni karibu masaa 3000-5000. Wakati wa kukaribia maisha haya ya huduma, zingatia zaidi mabadiliko ya utendaji wake.
Synchronize with the running speed of the printing machineSpeed matching principle: The running speed of the printing machine and the heating time of the infrared heating lamp need to be closely matched. When the printing machine runs fast, it is necessary to ensure that the heating intensity of the heating lamp can keep up with the rhythm of printing, so that the ink can reach the curing requirements in the short time it passes through the heating area. For example, when the running speed of the printing machine is 10-20 meters/minute, the heating time of the heating lamp (determined by the running length and speed of the printing machine) should enable the ink to be fully dried and cured within this time range. The running speed and the parameters of the heating lamp can be adjusted through the control system of the printing machine to achieve synchronous optimization of the two.Dynamic adjustment strategy: According to the complexity of the printing pattern and the drying characteristics of the ink, the speed of the printing machine and the parameters of the heating lamp are dynamically adjusted. For simple printing patterns and easy-to-dry inks, the speed of the printing machine can be appropriately increased; for complex patterns and difficult-to-dry inks, the speed should be reduced or the heating intensity of the heating lamp should be increased to ensure the printing quality.
Regularly maintain and clean the heating lampClean the surface dust and impurities: During the printing process, impurities such as dust, fibers and ink droplets may accumulate on the surface of the heating lamp. These impurities will affect the emission and penetration of infrared rays and reduce heating efficiency. Wipe the surface of the heating lamp regularly (such as once a week) with a clean soft cloth or a special cleaning tool to keep it clean. For stubborn impurities, you can use a small amount of mild detergent to clean it, but be careful to avoid the detergent from entering the inside of the quartz glass heating lamp.Check performance and replace parts: Regularly check the performance of the heating lamp, including temperature uniformity, luminous intensity, etc. If the temperature of the tungsten near infrared lamp is found to be uneven or the luminous intensity decreases, it may be that the components inside the IR Halogen Heating Bulb(such as the infrared emitting element) are faulty. According to the service life and actual performance of the heating lamp, replace the damaged parts in time to ensure that the Quartz Infrared Heating Elements always maintains an efficient working state. Generally speaking, the service life of halogen heat element is about 3000-5000 hours. When approaching this service life, pay more close attention to its performance changes.
