Description
[technical field]
The utility model relates to a kind of drafting system of textile machine, is that a kind of to adopt the squeezer apparatus of the spinning, drawing part that is applied to rove or spun yarn of pneumatic pressurization be reel cage specifically.
[technical background]
Progress along with spinning technique, pneumatic pressurizing cradle more and more receives publicity and payes attention to, present pneumatic pressurizing cradle can be divided into integral gasbag and independent air bags two classes, wherein the pneumatic pressurizing cradle of integral gasbag is not good because of the decay of its pressure and air pressure thereof and stressed linear relationship, exposed inevitable defective, generally will not adopt; Adopt the pneumatic pressurizing cradle of independent air bags then to highlight its advantage in the superperformance aspect above-mentioned two because of it, but there are following two aspect defectives in current independent air bags pneumatic pressurizing cradle: 1. adopt plug-type handle, and control the inflation of air bag and lose heart with this, the shortcoming of this mode is that mode of operation and traditional reel cage difference are too big, general woman worker is difficult for grasping, and this plug-type handle difficulty that resets, thereby cause the inflation of air bag and the control of losing heart malfunctioning; 2. adopt elasticity to start the location after the reel cage release, this elastic positioning device makes the user can cause the swing by a relatively large margin of reel cage body when the loading and unloading top roller, has reduced the convenience of using.
[summary of the invention]
For overcoming the existing defective that adopts the pneumatic pressurizing cradle of independent air bags, the utility model provides a kind of novel spinning, drawing and pressuring device, and to improve the reliability of reel cage to gas control, handled easily reduces cost.
For solving its technical problem, the technical solution adopted in the utility model is: on the structure that has the pneumatic pressurizing cradle that adopts independent air bags now, plug-type handle changed into be the swing type handle, the open type stay changed into contain the enclosed stay, change former bearing pin into cam pin, and comprising handle (18), rocking arm and base (10), reel cage body (1), have additional shift fork (13) in the four-bar mechanism of stay (8) and cam pin (6), this shift fork (13) can rotate around the straight pin (14) on the reel cage body (1), one end is located at gas valve core (16) top, the other end has the track groove of an opening, the straight pin of being located on the handle (18) (12) is positioned at its track groove, by the rotation of handle (17), shift fork (13) compresses or unclamps gas valve core (15) and makes air bag (18) inflate or lose heart; Reliable self-locking and the release that this device is obtained under pressurized state by the four-bar mechanism that includes stay (8) simultaneously starts stable rigidity location, back; By the rotation of air valve seat (17), realize the break-make of this device and external main gas circuit in addition with reel cage body (1).
Compared with prior art, the advantage of this utility model is: 1. because by swing handle control shift fork, overcome the problem that the handle difficulty resets, make to the inflation of air bag and the control of losing heart reliable; 2. because reel cage is the rigidity location after starting, be very easy to the loading and unloading of roller and to the work of saving from damage of roller etc.; 3. because adopted longer than former use open type stay in service life that the enclosed stay makes retaining mechanism; 4. because adopted cam pin, it is simple and convenient that the reel cage working depth is regulated.

[specific embodiment]
The rocking arm and base of this embodiment (10) is fixed on the special-shaped pole axle (4), the cooperation of its profiled holes can prevent the rotation of rocking arm and base (10) well, reel cage body (1) connects by bearing pin (14) and rocking arm and base (15), and can rotate around bearing pin (15), connect with straight pin (11) between handle of particular design (18) and the reel cage body (1), and can rotate around straight pin (11), establish in addition on the handle (18) by two straight pins (9) and (12), wherein straight pin (12) is in the track groove of shift fork (13) of particular design, lean on the amplitude of fluctuation of the curve controlled shift fork (13) of track groove with the rotation of handle (18), realize control with this to gas valve core (16) position, straight pin (9) then is in the track groove of enclosed stay (8), with the rotation of handle (18) and reel cage body (1) swing by the curve controlled enclosed stay (8) of track groove, and the appearance and size of enclosed stay (8) be particular design can finish in the process of starting to reel cage body (1) lift and start finish after to the rigidity positioning action of reel cage body (1).
Operation principle of the present utility model:
1, the duty and the gas passage in when pressurization, referring to Fig. 1:
During work, handle (18) is depressed until the upper surface that is adjacent to reel cage body (1), connect between external source of the gas and the air valve seat (17) this moment, gas enters air valve seat (17) cavity of resorption through flexible pipe (5), leakage display device (3), and the position that breaks away from gas valve core (15) also adjusted to shift fork (13) simultaneously by handle, and gas valve core (18) rises, air valve seat is communicated with air bag (19) inner chamber, gas enters into air bag (19) inner chamber, and gas compressing presser unit (2) produces the pressurization effect to roller.
2, the long relation of the bar of the tight mechanism of when pressurization four lever locks, referring to Fig. 2:
Be respectively L1, L2, L3, L4 by its bar length of four-bar mechanism that constitutes between enclosed stay (8), handle (17), reel cage body (1) and the rocking arm and base (10) during work, wherein L4 is a cradling piece, L2 is a driving lever, long L3 is invariable for bar, this mechanism produces self-locking down at the reaction force N ' of bottom roll, start handle (18) and just can make driving lever L2 action, otherwise self-locking can not be removed, so reliable lock, can also change the length of L1 and L4 in the four-bar mechanism by the direction that changes cam pin (6), thereby reach the purpose of adjusting reel cage body (1) working depth.
3, the gas release conditions in location of the rigidity during release and the air bag, referring to Fig. 3:
During release, manually start handle (18), at handle (18) when beginning to rotate, just can make shift fork (13) depress gas valve core (16), block air valve seat (17) cavity of resorption, stop source of the gas gas to continue to enter, and air valve seat (17) epicoele is communicated with atmosphere, the gas of air bag (19) inner chamber discharges thereupon, and the pressure of bottom roll is soon unloaded, this moment, starting of handle became light, when handle continues to start, straight pin (9) drives enclosed stay (8) and rotates, when the gabarit contact straight pin (7) of enclosed stay (8), in the process that continues to start, can lift reel cage body (1) gradually, in the groove of sliding people's enclosed stay (8) gabarit of straight pin (7), obtain reliable rigidity location thus, be convenient to carry out the maintenance partly of various counter extensioins, depress handle (18) except that non-return, otherwise can not remove.
