Description
Technical field
The utility model relates to a kind of parts of computer knitting machine, relates in particular to a kind of limit creel for thread take-up.
Background technology
The limit creel is indispensable parts in the computer knitting machine, play a part thread take-up, it mainly relies on the yarn pulling arm that is loaded with spring to finish thread take-up work, but traditional old-fashioned limit creel is when broken yarn occurring, yarn will eject the limit creel and get back to the antenna holder place, therefore need to again entry, affect the braid efficiency of straight-bar machines.
Based on this, Japan has developed a kind of improved limit creel, this limit creel is provided with the electromagnetism yarn gripper, it is important in sensor, electromagnet and burning into sand device form, operation principle: sensor is used for detecting the swing position of yarn pulling arm, in case swinging swing position, yarn pulling arm surpasses certain amplitude (situation that broken yarn namely occurs), sensor just can perceive rapidly, will drive magnet close, and then utilize the elastic force of spring that yarn gripper is closed, thus the yarn that broken clamped on the creel of limit, but this electromagnetism yarn gripper cost is higher, drop into too large, therefore be necessary to develop a kind of cheap and effect is good can yarn clipping the limit creel.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of cheap and practical reliable computer knitting machine limit creel for the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of computer knitting machine limit creel, comprise housing, be loaded with the yarn pulling arm of spring and the yarn gripper that links with yarn pulling arm, aforesaid housing has the hole of entrying of passing through for yarn, aforesaid yarn pulling arm by a rotating fulcrum lever be located on the aforesaid housing and have a hunting range, in the situation of yarn broken string, aforesaid yarn pulling arm can drive yarn gripper and finish the yarn clipping action, it is characterized in that described yarn pulling arm comprises push jack section and the body that is positioned at the rotating fulcrum two ends, this body is loaded with aforesaid spring
Described yarn gripper comprises
Sliding shoe can be located in the aforesaid housing and near push jack section and be positioned at the below, hole of entrying slidably, and this sliding shoe is connected with aforementioned push jack section by a U-shaped hook spare; And
Elastic component is located in the aforesaid housing and an end is butted on the drive block mutually,
Yarn is in running order lower, and aforesaid elastic component one end is butted on sliding shoe mutually, and it is static that sliding shoe keeps;
In the situation of yarn broken string, aforesaid yarn pulling arm amplitude of fluctuation surpasses hunting range, and aforesaid push jack section acts on the sliding shoe, and sliding shoe moves, and then makes elastic component further impel sliding shoe to move, and sliding shoe is clipped in inner walls with disconnected yarn.
Described sliding shoe comprises drive block and yarn clipping piece, and aforesaid drive block then is connected with push jack section by U-shaped hook spare, and aforesaid yarn clipping piece is connected with drive block and also can be subjected to the effect of drive block and can slides.The sliding shoe here can be that integral piece also can be comprised of drive block and yarn clipping piece, can design according to actual conditions.
Further, the front end of described yarn clipping piece has a groove, and accordingly, described inner walls has a projection that cooperates to clamp yarn with aforementioned grooves.
Described elastic component is one to be located at torsion spring in the housing by a pivot pin, and an end and the inner walls of this torsion spring offset, and the upper end of the other end and drive block offsets.Certainly elastic component can also adopt reed.
As preferably, the rear end of described drive block has for the first forced section of push jack section effect and the second forced section that drives for torsion spring, aforesaid the first force part is in the second forced section below, the bottom of described drive block has a junction, this connecting portion is provided with a minor axis, and described U-shaped hook spare then hook is located on this minor axis and can be moved around.
Further, the end of described U-shaped hook spare has the limiting section that a restriction U-shaped hook spare breaks away from short pin.
Compared with prior art, the utility model has the advantage of: in the situation of yarn broken string, yarn pulling arm is subjected to the spring action amplitude of fluctuation to surpass hunting range, push jack section acts on the sliding shoe, sliding shoe moves, and then making elastic component further impel sliding shoe to move, sliding shoe is clipped in inner walls with disconnected yarn.Adopt mechanical type to replace electromagnetic type, cost reduces greatly, and each parts no-float, and effect is reliable, can substitute the electromagnetic type yarn gripping structure fully, is beneficial on a large scale and uses.
Description of drawings
Fig. 1 is embodiment 1 yarn structural representation when in running order.
Push jack section acted on the structural representation of drive block when Fig. 2 was embodiment 1 broken yarn.
Fig. 3 be among the embodiment 1 during broken yarn torsion spring act on the structural representation of drive block.
Fig. 4 is embodiment 2 structural representations.
Fig. 5 is embodiment 3 structural representations.
The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
For making yarn clipping piece 4 can effectively clamp disconnected yarn 100, the front end of yarn clipping piece 4 has a groove 41, accordingly, housing 1 inwall have one with the projection 12 of groove fit to clamp yarn.
The rear end of drive block 5 has for the first forced section 51 of push jack section 22 effects and the second forced section 52 that drives for torsion spring, the first forced section 51 is positioned at the second forced section 5 belows, the bottom of drive block 5 has a junction 53, this connecting portion 53 is provided with a minor axis, and U-shaped hook spare 23 then hook is located on this minor axis and can be moved around.
