Ucwaningo lwe-ultrasonic plastic welding equipment structure-I

Enqubweni yokukhiqiza imikhiqizo yepulasitiki, ubuchwepheshe be-welding be-ultrasonic bungavala imikhiqizo yepulasitiki ngokushesha nangempumelelo.Ngaphandle kwalokho, ngesikhathi sokubekwa uphawu, asikho isidingo sokuba nemikhiqizo yepulasitiki yokushisa ngaphandle noma asikho isidingo sanoma iyiphi i-flux, umphumela wokushisela muhle kakhulu futhi amandla okushisela nawo aphezulu kakhulu.Ngesikhathi sobuchwepheshe be-welding ye-ultrasonic ekusetshenzisweni kwesicelo, izici zezindleko eziphansi nokuphepha okuphezulu futhi kwenza ukuthi kusetshenziswe kabanzi emikhiqizweni yemishini yepulasitiki, imboni yokubhala, imboni yezimonyo, imboni yamathoyizi, imboni kagesi.

1. Ubuchwepheshe bokushisela ipulasitiki ye-ultrasonic kanye nezici zayo

1. 1 Ubuchwepheshe bokushisela ipulasitiki be-ultrasonic

Ubuchwepheshe bokushisela ipulasitiki be-ultrasonic ukushisela imikhiqizo yepulasitiki ndawonye ngokusebenzisa isimiso sokudlidliza se-ultrasonic.Lapho i-wave ye-ultrasonic isetshenziselwa ukushisela ama-welds epulasitiki, ukungqubuzana kuzokwenzeka phakathi kwama-molecule e-wave ye-ultrasonic kanye nendawo yokuxhumana yemikhiqizo yepulasitiki, bese izinga lokushisa lokushisela endaweni yokushisela epulasitiki lifinyelela ngokushesha endaweni yokuncibilika. ipulasitiki.Ngalesi sikhathi, ukuncibilika kwezinsimbi ezimbili zepulasitiki kuzogeleza ndawonye.Lapho ama-molecule e-ultrasonic wave eyeka ukudlidliza, Ipulasitiki iyancibilika ingaphansi kwengcindezi futhi iqina ngokushesha futhi icwebezele, okwenza ukushisela kulingane.Amandla wephoyinti lokushisela asondelene nalawo wempahla eluhlaza.Ukuze uhlanganise ama-welds emishini epulasitiki ndawonye, ​​kuyadingeka ukuqinisekisa ukuthi ukushisa okukhiqizwa igagasi le-ultrasonic kungenzeka kuphela endaweni yokushisela, futhi isakhiwo esiqondisayo samandla esihambisanayo kufanele sisetshenziselwe ukudlulisa nokuqondisa ukushisa okukhiqizwa igagasi le-ultrasonic, futhi isakhiwo sokuqondisa amandla sibizwa nangokuthi isakhiwo se-welding wire.

1.2 Izici zobuchwepheshe bokushisela ipulasitiki ye-ultrasonic

Ubuchwepheshe bokushisela ipulasitiki be-ultrasonic bufaneleka kuphela i-thermoplastics, futhi kwezinye izinto azifanele ukusetshenziswa.isizathu sokukhetha i-thermoplastics ukuthi izakhiwo zamakhemikhali nezomzimba ze-thermoplastics zihlala zingashintshile lapho zincibilika bese zelashwa.I-Thermoplastics ingahlukaniswa ibe yi-crystalline ne-amorphous ngokusho kwezakhiwo zabo.Phakathi kwazo, indawo encibilikayo yepulasitiki ye-crystalline iyabonakala, futhi ama-molecule ayo angaphakathi azohlelwa ngokuhambisana nemithetho ehambisanayo lapho ephulukisa ukuze enze isifunda se-crystal.
