Abstract
The utility model discloses a joint yarn drift prevention device and belongs to the field of textile machine part devices. A yarn drifting and knotting phenomenon exists in the process of jointing yarns in a conventional joint device. The joint yarn drift prevention device disclosed by the utility model comprises a bottom plate, a limiting block which is fixedly arranged on the bottom plate, a filament retaining rod and a pressing plate, wherein a U-shaped opening which corresponds to an opening in the bottom plate is formed in the limiting block; the width of the U-shaped opening is smaller than the width of the opening in the bottom plate; the filament retaining rod comprises a mounting part, a supporting part and a limiting part; the mounting part comprises a connecting ring and a connecting rod which are connected into a whole and are fixed on the bottom plate through screws; the connecting rod is embedded in a groove formed in the connecting rod which corresponds to the bottom of the bottom plate and is fixedly pressed on the bottom plate through the pressing plate; the supporting part is a supporting rod which is vertically arranged; the bottom end of the supporting rod is fixedly connected to the connecting rod; the top end of the supporting rod is fixedly connected to a supporting leg of a U-shaped overhanging rod, so that the U-shaped overhanging rod is in a transverse overhanging shape and corresponds to the U-shaped opening; the end part of the other supporting leg of the U-shaped overhanging rod is bent outwards to form a flaring. According to the device, the yarn drifting and knotting phenomenon difficultly occurs in the process of jointing the yarns.
Description
Technical field
The utility model belongs to frame part device field, especially relevant with the anti-yarn feeding device that wafts of a kind of joint.
Background technology
The pneumatic type piecing devices of bleeder open-end spinning frame are in the time just starting joint, yarn is in loose state, can there is because do not strain one section of loose yarn in yarn, add the effect of external force, yarn there will be the phenomenon of the yarn knotting of wafing, so just reduced the success rate of joint, and yarn cylinder there will be across limit yarn, affect the processing of yarn moulding and later process.
Utility model content
The purpose of this utility model is intended to overcome yarn in existing piecing devices and in the time of joint, exists and waft yarn knotting and cause the phenomenon that joint success rate is low, provides a kind of yarn not to be prone in the time of joint to waft the anti-yarn feeding device that wafts of joint of yarn knotting.
For this reason, the utility model is by the following technical solutions: the anti-yarn feeding device that wafts of a kind of joint, it is characterized in that: the anti-yarn feeding device that wafts of described joint comprises base plate, limited block, gear screw mandrel and pressing plate, base plate is provided with an opening on one side, limited block is fixedly installed on described base plate, on limited block, be provided with the U-shaped opening corresponding with opening on described base plate, the width of U-shaped opening is less than the A/F on described base plate, described gear screw mandrel comprises installation portion, support portion and limiting section, installation portion comprises the connecting ring and the connecting rod that are connected as a single entity, connecting ring is fixed on base plate by screw, described pressing plate bottom is provided with the groove corresponding with described connecting rod, described connecting rod fixedly press-fits on described base plate by pressing plate, described connecting rod is flush-mounted in described groove, support portion is a vertical support bar arranging, support bar bottom is fixedly connected on described connecting rod, described limiting section is positioned at the top of described limited block, limiting section is the U-shaped bar that overhangs, the overhang end of a leg of bar of U-shaped is fixedly connected on described supporting bar top, make the U-shaped bar that overhangs be the shape corresponding with described U-shaped opening that laterally overhangs, overhang outwardly-bent formation one enlarging of another leg end portions of bar of U-shaped, is convenient to the advance and retreat that yarn overhangs in bar at U-shaped.
The utility model can reach following beneficial effect: by gear screw mandrel being set in the anti-yarn feeding device that wafts of joint, the U-shaped that yarn can be limited in gear screw mandrel in the time of joint overhangs in bar, by increasing the resistance of yarn, yarn is not prone to waft the phenomenon of yarn knotting, thereby improve the joint success rate of yarn, make the coiling of yarn cylinder evenly, improve the quality of yarn cylinder.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation that keeps off screw mandrel described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As depicted in figs. 1 and 2, the utility model comprises base plate 5, limited block 8, gear screw mandrel 7 and pressing plate 3, base plate 5 is provided with an opening on one side, limited block 8 is fixedly installed on base plate 5, on limited block 8, be provided with the U-shaped opening corresponding with opening on described base plate 5, the width of U-shaped opening is less than the A/F on described base plate 5, gear screw mandrel 7 comprises installation portion, support portion and limiting section, installation portion comprises the connecting ring 9 and the connecting rod 10 that are connected as a single entity, connecting ring 9 is fixed on base plate 5 by screw 2, the bottom of pressing plate 3 is provided with the groove corresponding with described connecting rod 10, connecting rod 10 fixedly press-fits on base plate 5 by pressing plate 3, connecting rod 10 is flush-mounted in described groove, support portion is a vertical support bar 4 arranging, support bar 4 bottoms are fixedly connected on connecting rod 10, described limiting section is positioned at the top of limited block 8, limiting section is the U-shaped bar 1 that overhangs, the overhang end of a leg of bar 1 of U-shaped is fixedly connected on the top of support bar 4, make the U-shaped bar 1 that overhangs be the shape corresponding with described U-shaped opening that overhangs, overhang outwardly-bent formation one enlarging of another leg end portions 6 of bar 1 of U-shaped, be convenient to the advance and retreat that yarn overhangs in bar 1 at U-shaped, U-shaped overhangs bar 1 for lateral inclination shape, when joint, yarn is resisted against overhang two legs of bar 1 of U-shaped simultaneously, increase the resistance of yarn, make yarn be limited in the phenomenon that U-shaped overhangs in bar 1 and is not prone to the yarn knotting of wafing.
