KHK-A 型吊锭支片动作过程：支片动作由棘轮、棘爪机构来实现。棘轮装在机芯上，机芯由支撑圈推动带动棘轮作上下运动，棘爪为一特殊形状的弹簧钢片，棘爪固定在机 芯旁当机芯作上下运动时会撑低效率棘轮，使棘轮旋转过90度，机芯作上位、下位交替循环动作，上位时支片收入，下位时支片伸出。动作的可靠性由棘轮、棘爪 机构保证，棘轮由弹簧钢片压住保证其始终处于受控状态，此种传动机构可靠耐用且消除了产生动作误差的可能性。
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.
