差速軸如何提升多捲複捲品質

A differential shaft improves multi-roll rewinding by letting each rewind roll hold its own tension, so uneven rolls wind evenly without telescoping or core slip.

如何保養差速軸

Differential shaft maintenance keeps multi-roll rewinders producing uniform rolls. Daily checks, cleaning steps, and wear-part swaps prevent uneven tension.

如何挑選正確的氣脹軸軸心轉接頭：3 吋與 6 吋對決

什麼是氣脹軸軸心轉接頭？ 氣脹軸軸心轉接頭（又稱捲芯轉接頭或夾頭轉接頭）是安裝於氣脹軸與紙、薄膜或箔材捲芯之間的機械套筒。當您捲芯內徑與軸的標準直徑不符時，它便能橋接其間差距，例如把 3 吋（76 mm）的軸改用於 6 吋（152 mm）的捲芯，或反向為之。 選錯轉接頭會導致捲芯打滑、張力不均、提早磨損，甚至機台停機。本指南帶您逐一檢視採購前該評估的關鍵規格。 該評估的關鍵規格 1. 捲芯內徑（ID） 最根本的尺寸，就是您所用捲芯的內徑。轉換加工與印刷的標準尺寸有： 3 吋（76 mm）：窄幅捲材、標籤與輕量薄膜常用 6 吋（152 mm）：寬幅轉換加工、厚紙板與大徑捲收捲的標準 務必仔細量測捲芯內徑。即使 1–2 mm 的誤差，也可能在高速下造成轉接頭抖動。 2. 軸外徑（OD） 您的氣脹軸在洩氣時有標稱外徑、充氣時有膨脹外徑。轉接頭必須緊密套合軸的膨脹外徑，才能無打滑地傳遞扭力。訂購前，請先由軸的規格表確認軸外徑規格。 3. 轉接頭長度 轉接頭要夠長，才能與捲芯完全接觸，但不可長到干涉機台側框或法蘭。一個實用的經驗法則：轉接頭長度 ≥...
