Description
Technical field
The utility model patent relates to a kind of release unit, relates in particular to a kind of shank release unit that is used for the locking-type machine of textile machine.
Background technology
Present existing locking-type plain embroidery mixer, when plain embroidery was partly worked, the drive block of locking-type part was also moving up and down, thereby shank also moves up and down, therefore constantly work by electromagnet, drive block just can turn, and shank just can quit work, and causes the electromagnet long-term work like this, influence the life-span, and constantly clash into drive block, and the life-span of drive block is also fallen, also have big noise to produce simultaneously.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, provides a kind of when plain embroidery is partly worked, and drive block can't embed the inner shank release unit that is used for the locking-type machine with top dead-centre.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of shank release unit that is used for the locking-type machine, comprise the locking-type casing, be provided with needle bar mechanism and follower lever mechanism in the described locking-type casing, described needle bar mechanism comprises shank, bottom dead centre, shank compressing tablet and back-moving spring, described shank is located in the needle bar hole of locking-type casing, the upper end of described shank is with back-moving spring, and described shank middle part is with bottom dead centre, and described shank compressing tablet and shank fix; Described follower lever mechanism comprises follower lever, cushion pad, the follower lever compressing tablet, the cylinder compressing tablet, cylinder and cylinder supports, described follower lever is located in the follower lever hole of locking-type casing, described locking-type casing is provided with cylinder supports, cylinder supports and cylinder fix, described cylinder compressing tablet and cylinder fix, described cylinder compressing tablet is locked mutually with follower lever, the top and bottom of described follower lever compressing tablet are respectively equipped with cushion pad, described cushion pad is enclosed within follower lever, described follower lever compressing tablet is locked mutually with follower lever, be provided with drive block in the described locking-type casing, it is corresponding that described drive block and bottom dead centre are complementary, and described follower lever compressing tablet drives the shank compressing tablet and does and move upward.
By cylinder supports cylinder is fixed, cylinder compressing tablet on its cylinder causes cylinder compressing tablet drive follower lever to be done and moves upward along with the running of cylinder, and the follower lever compressing tablet drives the shank compressing tablet and moves upward, it is inner that thereby drive block can't embed top dead-centre, the service life of having improved drive block.
As preferably, described cylinder supports is located at the lateral wall of locking-type casing, and the lateral wall of locking-type casing is provided with jack hole, and described cylinder compressing tablet passes jack hole and locks mutually with follower lever.
As preferably, described bottom dead centre and shank fix by lock screw, and described shank compressing tablet and shank fix by screw.
Therefore, the shank release unit that is used for the locking-type machine of the present utility model, compact conformation prolongs service life of equipment, avoids the generation of noise simultaneously.
