Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of flat knitting machine, more particularly to a head front and back symmetry degree detection frock of double needle bar flat knitting machine. BACKGROUND

[0002] The head of the flat knitting machine is the core component of the flat knitting machine, which is responsible for assembling the cam bottom plate and each cam block, connecting the front and rear two cam devices into one, and driving the cam device to move along the needle bed transversely to push the knitting needle to complete the knitting action.

[0003] The head of the double needle bar flat knitting machine is a saddle-shaped structure, which is straddled on the needle bed arranged in an inverted V shape. This structure design enables the head to work with the front and rear two needle beds at the same time, realizing the front and back symmetric knitting action.

[0004] During knitting, the needle bed is stationary, and the yarn guide is driven by the head to move along the needle bed to push the knitting needle to rise and fall in the needle groove. One to several loop forming systems can be configured in the head, and the "cam" structure of each loop forming system is usually symmetrical in front and back and left and right.

[0005] The front head and the rear head are connected through the connecting arm, which ensures the synchronous movement of the front and rear heads during knitting and maintains the front and back symmetry. The existing double needle bar flat knitting machine is difficult to ensure the consistency of the head assembly structure when assembling and adjusting the symmetric structure of the head through the experience of the staff.

[0006] Therefore, how to realize the rapid construction of the head assembly structure is a problem to be solved by the technical personnel in the field. CONTENT OF THE UTILITY MODEL
