Description
Technical field
The present invention relates to a kind of Speed frames.
Background technology
Common Speed frames need end finger on flier to be separated rove with between the bobbin of full rove.In these yarn machines, by being resisted against the pressing device on the coiling stroke of last position, utilizing the raising of the rotating speed of each long measure, being thought the raising of the flier rotating speed ratio of flier supply rove by drawing frame, generating rove section.The rove section with higher-strength has drawing frame feeding, is transported to pressing device by the rotation of bobbin.Finally, the rove between pressing device and bobbin is relaxed by the revolution of bobbin, and when the sinking of bobbin rail, rove is separated in withdrawn position.
There is certain defect in such Speed frames, namely the length of rove rove end that pressing device is sagging when being separated has very large change depending on concrete condition.Therefore, separation point position is not accurately had.
Summary of the invention
Object of the present invention, is for solving the above-mentioned defect of prior art, and provides one to have Speed frames, and these Speed frames can accurate promptly cutting and separating rove.
The technical solution adopted in the present invention is:
Rove yarn cylinder;
Bobbin, is rotatably placed on described rove yarn cylinder;
Wire turn, is wound in described bobbin;
Pressing device, for being resisted against described bobbin by wire turn;
Flier;
Bobbin rail, is provided with described rove yarn cylinder, and can vertical lift;
Described pressing device comprises the upper pressing device of horizontal segmentation and lower pressing device, and lower pressing device is articulated in flier; The side of described upper pressing device bobbin is dorsad fixed with support bar, and described lower pressing device is provided with the through hole passed for support bar; Support bar, and to be declined when described bobbin rail is in and replaces position by jack-up when described bobbin rail is in operating position, pushes down lower pressing device to described upper pressing device; The medial surface of described pressing device for axis, enters at medial surface rove the bellmouth entrance that side concave shaped becomes symmetrical with the contact surface of described upper pressing device and lower pressing device, and the horizontal groove that rear, bellmouth entrance connects; The upper and lower of the junction of groove and bellmouth entrance has vertical blade.
Therefore, the beneficial effect of these Speed frames is: when these Speed frames utilize coiling, bobbin rotates to be the horizontal pull driving rove to produce, and the pressure of pressing device, make rove when by pressing device, be easy to enter bellmouth entrance inside pressing device, and pass through groove according to the shape of bellmouth entrance, when bobbin rail declines, blade on pressing device applies pressure to the rove at groove mouth place, and coordinate bobbin to rotate the horizontal pull produced, the rove in groove is easily ruptured, thus reaches the object of accurately cutting and separating rove rapidly.

Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not limitation of the present invention being interpreted as.
In describing the invention, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, connect integratedly, also can be removably connect; Can be mechanical connection, also can be the connection of two element internals; Can be directly be connected, also indirectly can be connected by intermediary, for the ordinary skill in the art, the concrete meaning of above-mentioned term can be understood as the case may be.
It should be noted that, unless otherwise clearly defined and limited, term " first ", " second " etc. do not represent order and install, and do not represent the importance of described element yet.
And exemplify following examples to describe Speed frames of the present invention in detail below with reference to the accompanying drawings:
Please refer to Fig. 1 to Fig. 3,
A kind of Speed frames rove yarn cylinder 10;
Bobbin 20, is rotatably placed on rove yarn cylinder 10;
Wire turn 30, is wound in bobbin 20;
Pressing device 40, for being resisted against bobbin 20 by wire turn 30; Pressing device 40 in Speed frames run, according to the access location of wire turn 30, can change the position relative to bobbin 20 along bobbin 20 periphery in certain area.
Flier 60;
Bobbin rail 70, be provided with rove yarn cylinder 10, bobbin rail 70 is other stands guider 73, guider 73 is provided with the horizontal support arms 74 that vertically can regulate height, support arm 74 is provided with multiple for controlling the hydraulic cylinder 72 that bobbin rail 70 is elevated above, and hydraulic cylinder 72 can support bobbin rail 70 vertical lift; When being in operating position, bobbin rail 70 is in its extreme higher position; When bobbin 20 replaced by needs, bobbin rail 70 drops to the replacement position of lowest order;
Pressing device 40 comprises the upper pressing device 42 of horizontal segmentation and lower pressing device 44, and lower pressing device 44 is articulated in flier 60; The side of upper pressing device 42 bobbin 20 is dorsad fixed with support bar 46, and lower pressing device 44 is provided with the through hole 48 passed for support bar 46; Support bar 46 when bobbin rail 70 is in operating position by jack-up, and bobbin rail 70 be in replace position time decline, supreme pressing device 42 pushes down lower pressing device 44; The above pressing device 42 of medial surface of pressing device 40 and the contact surface of lower pressing device 44 are axis, enter at medial surface rove the bellmouth entrance 52 that side concave shaped becomes symmetry, and the horizontal groove 54 that rear, bellmouth entrance 52 connects; Groove 54 has vertical blade 56 with the upper and lower of the junction of bellmouth entrance 52.
Please refer to Fig. 2 and Fig. 3, the using method of these Speed frames is: during work, bobbin 20 rotates and draws rove becomes wire turn 30 to be wound around, the position of adjustment pressing device 40 is in the access location of rove 32, be resisted against by pressing device 40 on wire turn 30, now, bobbin rail 70 withstands support bar 46, pressing device 42 is separated with lower pressing device 44, and blade 56 separately; Rove, by the pressure of pressing device 40, enters from the bellmouth entrance 52 of indent, and successively by after blade 56 and groove 54, is enwinded by bobbin 20; When wire turn 30 is wound around complete, when being separated from rove yarn cylinder 10 by wire turn 30, bobbin rail 70 declines, and support bar 46 and upper pressing device 42 are moved down jointly, after the rove 32 at blade 56 closing of cutting cutting edge place, and wire turn 30 and rove below and separable.
