The invention is further described below with reference to examples.

Example 1

This embodiment relates to a mechanism for braiding a dirty braid of a dirty braid machine, i.e. the portion shown in fig. 1 adjacent to the working head 20. The dirty braid knitting mechanism includes a working head 20 and a crochet hook 11 capable of reciprocating in the working head 20, the crochet hook 11 has a structure similar to that of a crochet hook in a conventional dirty braid machine, and a tip of the crochet hook 11 has a groove structure, so that part of hair can be driven to push and pull in a hair bundle inserting process. The working head 20 comprises a fixing seat 21 and a rotating sleeve 22, the fixing seat 21 is used for being connected with the machine body 10, the rotating sleeve 22 is axially and rotatably arranged on the fixing seat 21 and can perform controlled rotary motion on the fixing seat 21, a hair inlet through hole for passing a hair bundle is formed in the inner side of the rotating sleeve 22, the end part of the crochet hook 11 can extend into the hair inlet through hole to insert the hair bundle, and a hair clamping structure capable of enabling the hair bundle to rotate along with the rotating sleeve 22 is further arranged on the wall of the hair inlet through hole of the rotating sleeve 22. In the knitting process, the crochet hook 11 reciprocates while penetrating and moving, and the rotating sleeve 22 drives the hair bundle to rotate without manually rotating the hair bundle or rotating the dirty braid machine, so that the knitting work is easier and more labor-saving, and the knitting efficiency and quality are higher.

The hair clamping structure can drive the hair bundle to circumferentially rotate, and can be a boss, a tooth shape and other structures positioned on the inner wall of the rotating sleeve 22. In this embodiment, the hair clamping structure is preferably a plurality of hair clamping grooves 22-1 formed on the wall of the hair through hole of the rotating sleeve 22, and the hair clamping grooves 22-1 are preferably arranged along the direction of the bus of the hair through hole, so that the structure is simple, the manufacturing is easy, part of hair can be stably clamped in the circumferential direction of the hair bundle to drive the hair bundle to rotate, and the hair bundle can freely move along the length direction of the hair bundle, thereby being convenient and flexible to operate.

The rotating sleeve 22 can adopt a reciprocating rotating structure or a unidirectional rotating structure on the fixed seat 21, namely, the rotating sleeve 22 can rotate forward and backward within a certain angle range and can also rotate in a unidirectional way along a clockwise direction or a counterclockwise direction. The reciprocating rotation of the rotating sleeve 22 is similar to the manual repeated twisting motion, and the unidirectional rotation is similar to the manual unidirectional rotation of the hair bundle. Both rotating structures can ensure that the crochet needle 11 uniformly penetrates the hair bundles, so that the dirty braids are woven more uniformly.

Preferably, in the present embodiment, the rotation movement of the rotating sleeve 22 is associated with the reciprocal penetration movement of the crochet needle 11, so that the hair bundle rotation movement is more stable in cooperation with the reciprocal movement of the crochet needle 11, which helps to further improve the knitting uniformity. The driving of the rotating sleeve 22 can be a single driving or a driving by the reciprocating motion of the crochet needle 11. When the rotating sleeve 22 is independently driven, an independent driving motor can be arranged, an outer gear ring is arranged on the outer side of the rotating sleeve 22, the driving motor is meshed with the outer gear ring through a gear to drive the rotating sleeve 22 to rotate, at the moment, the rotating sleeve 22 can be driven to reciprocate or unidirectionally rotate through the rotating direction of the driving motor, and the association of the motion actions of the driving motor and the reciprocating driving mechanism of the crochet hook 11 can be realized through controlling the working states of the driving motor and the reciprocating driving mechanism. When the rotating sleeve 22 is driven by the reciprocating motion of the crochet needle 11, a transmission mechanism for converting the reciprocating penetrating motion of the crochet needle 11 into the rotating motion of the rotating sleeve 22 can be arranged in the fixed seat 21, compared with the independent driving of the transmission mechanism, the rotating sleeve 22 is driven to rotate by the reciprocating motion of the crochet needle 11, a driving source of the rotating sleeve 22 is not required to be additionally arranged, the structure is simpler and more compact, the rotating sleeve 22 and the crochet needle 11 are in linkage motion, and the matching is more stable and reliable. The transmission mechanism can be in a structure of a gear rack, a ratchet wheel and the like, and can be any existing transmission structure capable of converting reciprocating linear motion into rotary motion. At this time, the reciprocating rotation of the rotating sleeve 22 can be realized through the reciprocating motion of a gear rack, for example, an outer gear ring is arranged on the outer side of the rotating sleeve 22, a rack meshed with the outer gear ring is arranged on the reciprocating motion mechanism of the crochet hook 11, and the reciprocating linear motion of the rack can drive the rotating sleeve 22 to rotate forward and backward in the moving range; the unidirectional rotation of the rotating sleeve 22 can be realized by a transmission principle such as a ratchet wheel or a unidirectional bearing, for example, an outer gear ring is arranged on the outer side of the rotating sleeve 22 through the unidirectional bearing (or an overrunning clutch), a rack meshed with the outer gear ring is arranged on the reciprocating mechanism of the crochet hook 11, the rack is meshed with the outer gear ring to drive the rotating sleeve 22 to rotate forward and backward, but only one direction can drive the rotating sleeve 22 to rotate under the action of the unidirectional bearing, and the reverse rotation of the rotating sleeve 22 can be limited by a ratchet wheel pawl structure, so that the rotating sleeve 22 can intermittently rotate towards one direction. It should be appreciated that when the rotating sleeve 22 is in unidirectional rotational movement, the rotating sleeve 22 is positioned above or below the crochet hook 11 so that no moving interference occurs between the two.

In this embodiment, the rotating sleeve 22 is preferably configured to reciprocally rotate.

The transmission pin 23 is adopted to realize the transmission of the rotating sleeve 22 and the crochet hook 11, the structure is simpler and more compact, and the transmission is stable and reliable. When the hook needle 11 moves into the hair-feeding through hole to drive the transmission pin 23 to move forwards, the transmission pin 23 pushes the stop block 22-3 to enable the rotating sleeve 22 to rotate, and at the moment, the spring 24 is compressed; when the crochet hook 11 moves reversely, the transmission pin 23 loses the thrust action, the rotating sleeve 22 rotates reversely under the elastic force of the spring 24, and the transmission pin 23 is reset. In order to facilitate the assembly of the driving pin 23 and the spring 24, in this embodiment, the fixing seat 21 is composed of two parts of the seat body 21-1 and the cover 21-2, the driving pin 23 can be inserted into the seat body 21-1 from the outer side of the seat body 21-1 and has its end portion abutted against the stopper 22-3, then the spring 24 is put into from the outer side, and the cover 21-2 is fixed on the seat body 21-1 so that one end of the spring 24 abuts against the stopper 22-3 and the other end abuts against the cover 21-2. The cover 21-2 and the base 21-1 can be connected and fixed by using a buckle and/or a screw. For convenience of manufacture, the cover 21-2 in this embodiment has a U-shaped structure, which is wrapped around the outer periphery of the base 21-1 during installation. As shown in fig. 12, in this embodiment, the crochet hook 11 is located in the middle of the rotating sleeve 22, and the rotating sleeve 22 is further provided with a avoiding hole 22-2 through which the crochet hook 11 passes, and the avoiding hole 22-2 is a long strip hole, so that the rotation of the rotating sleeve 22 and the reciprocating penetration movement of the crochet hook 11 do not interfere.
