KHK-A型吊锭应用在各种细纱机的悬锭粗纱架上，适配各种型号粗纱管纺纱。吊锭注册商标“KHK”和
“CF-KHK”。
 吊锭在粗纱架上主要用途有两个：

        1、依靠支片的伸出和收入来更换粗纱：

        2、依靠吊锭适当而稳定的牵引力来保证粗纱在纺纱过程中的正常旋转。（牵引力过大会使粗纱产生意外牵伸，牵引力过小会使粗纱退绕过快而落纱）。

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型吊锭牵引力控制方式：吊锭牵引力由阻尼压簧对阻尼垫片施加压力使吊锭子在旋转是产生阻尼摩擦力（牵引力），我们通过弹簧变形的距离来调节吊 锭有牵引力，弹簧变形距离由张力帽和张力盘分四档调节。根据不同的纺纱要求选择合适的吊锭牵引力，使粗纱在牵伸过程不产生意外牵伸，避免退绕过快。

KHK-A吊锭与原有吊锭相比其优点为：动作精准、牵引力适当、可靠耐用。

注：常规使用第二档。

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 90?, 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.
