Description

TECHNICAL FIELD

[0001] The present application relates to the field of textile equipment, in particular to a full-automatic hank twisting machine twisting mechanism. BACKGROUND

[0002] The hank twisting machine is a machine that twists the yarn on the cone into hank yarn, and then dyes the hank yarn. If the hank yarn is dyed as a whole, the yarn in the middle of the hank yarn will not be dyed evenly, so the hank yarn needs to be bundled and twisted to ensure even dyeing.

[0003] Currently, the twisting step of the traditional hank twisting machine is completely manual. It takes an average of 15 minutes to complete the twisting step of one vehicle (usually 30 hanks), and the daily output limit of a worker is about 50 vehicles. Since the manual twisting speed has an upper limit, it cannot keep up with the speed of the machine, resulting in half of the machine's time being spent waiting for twisting after the winding is completed. The primary factor limiting the production of traditional hank twisting machines is the efficiency of personnel. The manual twisting of traditional hank twisting machines has process defects such as "large and small hanks", missed twisting, and loose knots.

[0004] To solve this problem, the existing automatic hank twisting machine twisting module on the market uses a mobile cart as a mobile platform, and one twisting module is responsible for twisting two machines. Although it can partially replace manual work, the overall twisting efficiency is not improved compared to manual work. The existing automatic hank twisting machine twisting module on the market lacks automation and cannot cooperate with variable frame length spools.
