Description

The built-in quilting machines head of split

Affiliated technical field:

The built-in quilting machines head of the utility model split, it is a kind of novel quilting machines head.

Background technology:

The existing long-armed car of Sewing machines is subjected to the type restriction can not make large-scale bedding and clothing more, the use of the multimachine head quilting machines that can not suit, and general presser bar lifting mechanisms is installed in the casing outside more, by oily, the greasy dirt bedding and clothing that splash, and also outward appearance is not beautiful, operates dangerous.

Summary of the invention:

For overcoming the common fault of above head, the utility model provides the built-in quilting machines head of a kind of novel split to solve the common fault of above head.

The technical scheme that its technical problem that solves the utility model adopts is: go up the upper bearing (metal) (3) that main shaft (1) connects head (2) successively, the eccentric wheel that tape spool holds (4), connecting rod of eccentric wheel (5), connecting rod of eccentric wheel (5) one ends are regulated crank (6) and are dynamically connected, regulate the fixedly connected pressure foot lifting crank (8) that is installed in last two the lifting axle sleeves of head (2) (7) that penetrates of crank (6) other end, pressure foot lifting crank (8), pressure foot lifting connecting rod (9), depression bar contiguous block (10), presser bar spring bracket (11), presser bar (13) connects successively and is installed in the head (2), ball-type presser feet (14) is fixed on the presser bar (13), it is fixing by ring washer (25) that lower shaft (21) passes the lower bearing (24) that is fixed on down head (20), one end of lower shaft (21) is installed rotating shuttle (22), location hook (23) is fixed on down on the head (20) fixedly rotating shuttle (22), and last head (2) and following head (20) design for split.

The beneficial effects of the utility model are: the main shaft of quilting machines head can prolong makes large-scale bedding and clothing, built-in presser bar lifting mechanisms and shank assembly, has presser feet and shank synchronizing function up and down, make the even and input and output material convenience of foot pressure, no bouncing pilotage, broken needle, greasy dirt bedding and clothing not, characteristics such as the utility model quilting machines head noise is little, the life-span is long, handling safety is reliable can be increased the benefit greatly.
