Knee Lift Connecting Rod

 

Functions of Knee Lifter Rod

High-Speed Model Knee Control Adaptation
Aiming at the operation needs of 8800B high-speed lockstitch machines, the transmission response speed of the rod is increased by 20%; a light knee push can realize rapid presser foot lifting, which is suitable for the scenario of frequent fabric adjustment during high-speed sewing, freeing hands to focus on fabric straightening.

 

Precise Stroke Control
The φ7*80 specification is adapted to the transmission stroke of 8800B models, which can accurately control the presser foot lift height within the range of 8-12mm, meeting the switching sewing needs of medium-thick materials and thin materials, with no idle stroke deviation in transmission.

 

Low-Noise Transmission
A silent bearing is installed at the connection end between the rod and the internal lever, and the transmission noise is ≤35dB, suitable for the low-noise operation needs of high-speed models. The knee press lifting rod ensures quick and quiet presser foot adjustment for high-speed production.

Surface Treatment Methods of Knee Lifter Rod
 

Plating

Plating is a type of coating in which a metal is deposited on a conductive surface. Humans have employed this method from the beginning of time, and modern technology also makes use of it. The goal of plating can be aesthetic, prevent corrosion, improve solderability, harden, reduce friction, change conductivity, improve IR reflectivity, shield against radiation, etc.

Coating

Coating is covering the surface of an object. The object that is being coated is usually referred to as the substrate. Coating is important for decorative purposes, functional purposes, or for both. For example, paints and lacquers are important in protecting the surface of a substrate and also for decorative purposes. The functional properties of coating include adhesion, wettability, corrosion resistance, wear resistance, etc. Coating can completely cover the object or only some parts of the object.

A: A knee lifter rod moves the presser foot up by linking the knee lever to the sewing machine's lifting system.

Q: How does a knee lifter rod improve sewing tasks?

A: A knee lifter rod lets operators lift the presser foot without hands, increasing productivity and control in heavy-duty sewing.

Q: What machines use a knee lifter rod?

A: Industrial lockstitch and heavy-duty sewing machines use a knee lifter rod as part of the presser foot control mechanism.

Q: What material is a typical knee lifter rod made from?

A: A knee lifter rod is usually made of durable metal with strong joints to ensure long life under frequent use.

Q: Can a knee lifter rod be replaced easily?

A: A knee lifter rod can be replaced quickly with basic mechanical skills and correct fitment for the specific sewing machine model.

Q: Does a knee lifter rod affect presser foot travel?

A: Yes, a correctly sized knee lifter rod ensures the presser foot lifts smoothly and reaches the required height for material handling.

Q: How do I choose the right knee lifter rod?

A: Choose a knee lifter rod based on machine brand, model compatibility, length requirement, and connection style.
