KHK-A 型吊錠支片動作過程：支片動作由棘輪、棘爪機構來實現。棘輪裝在機芯上，機芯由支撐圈推動帶動棘輪作上下運動，棘爪為一特殊形狀的彈簧鋼片，棘爪固定在機 芯旁當機芯作上下運動時會撐低效率棘輪，使棘輪旋轉過90度，機芯作上位、下位交替循環動作，上位時支片收入，下位時支片伸出。動作的可靠性由棘輪、棘爪 機構保證，棘輪由彈簧鋼片壓住保證其始終處于受控狀態，此種傳動機構可靠耐用且消除了產生動作誤差的可能性。
KHK-A type bobbin hanger is applied to creel of various spinning frame, which can be suitable for spinning of all types of roving bobbin. Registered trademark of bobbin hanger is “KHK”, “CF-KHK”.
Main purposes of bobbin hanger on creel are given as below:
1. Replace the roving with extending and shrinking of branch sheet.
2. With proper and stable attractive force of bobbin hanger, it can ensure normal rotation of roving during spinning.
Action process of KHK-A type bobbin hanger branch sheet: it can be realized by ratchet wheel and click. Ratchet wheel is installed on core, the core is driven by supporting ring, taking the ratchet wheel up and down movement, ratchet wheel will be moved, when the ratchet wheel is rotated over 90o, core make upper and lower alternative circulation action, during upper position, branch sheet shrinks, during lower position, branch sheet extends. Action security is ensured by ratchet wheel and click mechanism. Ratchet wheel is pressed by spring steel sheet to ensure that it is in controlled status all the time. This driving mechanism is reliable and endurable and eliminates possible action error.
Controlled method of attraction force of KHK-A type bobbin hanger: damping spring press damping spacer to make the bobbin hanger rotate and generate damping friction force (attractive force), we can adjust attractive force of bobbin hanger through distance of spring transformation. The spring transformation distance can be adjusted for 4 grades by tensile nozzle and tensile disc. Proper attractive force of flyer spindle can be chosen according to different spinning requirements to make the roving generate normal drafting during drafting of roving and avoid rapid rewinding.
Compared with original bobbin hanger, KHK-A bobbin hanger has such advantages as accurate action, proper attraction force and reliability and durability.
Note: the second grade is used in normal procedure.
