ning igna ipiTugma teshigi tikuv mashinasi is cut by a cutter and then broken off, which is mainly caused by the failure of left and right, front and back, height, and opening time of cutter. It is recommended to check and adjust according to the following methods.
1. Yuqori ipni kesishning old va orqa harakatini sozlash
(1) Yuqori ipli qaychining old va orqa harakati 4 5 mm.
(2) Sozlash usuli: bosuvchi oyoq dastagining old uchida rolik milining mahkamlash vintini bo'shating, qaychining old va orqa harakatini oshirish uchun uni o'ngga siljiting va chapga kamaytiring.
2. Yon ip kesgichning chap va o'ng holatini sozlashTugma teshigi tikuv mashinasi
(1) Yuqori chiziqli qaychi tepaga harakat qilganda, u igna markaziga mos kelishi kerak va yuqori chiziqli qaychining old uchi kesuvchining tushgan markazidan o'ngga 5 mm dan oshishi kerak (1-rasm). ).
(2) Yuqori ipli qaychi yopilganda, harakatlanuvchi pichoq va mahkamlangan pichoq o'rtasida 0,3 0,5 mm qoplama yo'qligiga ishonch hosil qiling. Yuqori ip qaychi ustki ipni kesganda, ular mashina ignasida qolgan ip boshini ham qisishlari kerak va yana tikishda tikuv yuqori ip qaychidan tushmasligiga ishonch hosil qilishlari kerak.
(3) Yuqori ipli qaychining chap va o'ng holatini sozlash: Chap pedalga qadam qo'ying, ustki ipni kesuvchi yuqoriga qarab harakat qilganda, yuz chizig'i qaychi tebranish ramkasining mahkamlash vintini bo'shating va old, orqa tomonni rostlang. , tebranish ramkasini orqaga, chapga va o'ngga siljitish orqali yuqori ipli qaychi chap va o'ng pozitsiyalari.
(4) Yuqori ipli qaychining harakatlanuvchi to'sar va mahkamlangan kesgichning yopish miqdorini sozlash (2-rasm):
Loosen the fastening screw ② of the closing shear control board and move the closing shear control board ③ back and forth. When the closing shear control board ③ moves towards the operator, the closing time is delayed due to the reduction of the closing amount.
3. Yuqori ip kesgichning balandligini sozlashTugma teshigi tikuv mashinasi
Adjust the height of the thread cutter after the presser foot is lifted. The fixed cutter is required not to touch the presser foot. During movement, it is not allowed to touch the needle clamp, and try to lower the thread scissors. As shown in Figure 2, loosen the set screw ① of the face line scissors and move the face line scissors up and down for adjustment.
4. Ip kesgichning ochilish vaqtini sozlash
(1) Gorizontal tikuvga ta'sir qilmaslik sharti bilan, yuqori ipni uzoq vaqt davomida mahkamlash yaxshidir. Tikishni boshlaganda, yuqori ip qaychi bilan qisilgan ip boshi tashqariga chiqishiga yo'l qo'yilmaydi. Taxminan 3 5 ta tikuvdan keyin uni sekin oching.
(2) Adjustment method: loosen the screw ② in Figure 2 and move the shear opening control board ④ back and forth for adjustment. When moving towards the operator, the scissors are opened in advance. Note: do not cause the fixed shear closing control board ③ out of position.
