Description

Novel spinning, drawing and pressuring device

[technical field]

The present invention 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.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 invention provides a kind of novel spinning, drawing and pressuring device, to improve the reliability of reel cage to gas control, handled easily reduces cost.

For solving its technical problem, the technical solution used in the present invention is: on the structure that has the pneumatic pressurizing cradle that adopts independent air bags now, change plug-type handle into the swing type handle, change the open type stay into 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 machineries of stay 8 and cam pin 6, this shift fork 13 can rotate around the straight pin on the reel cage body 1 14, one end of shift fork 13 is located at gas valve core 16 tops, the other end is provided with the track groove of an opening, be located at the track groove that straight pin 12 on the handle 18 is positioned at shift fork 13, by the rotation of handle 18, shift fork 13 compresses or unclamps gas valve core and makes air bag 19 inflate or lose heart; Reliable self-locking and the release that this device is obtained under pressurized state by the four bar machineries that include stay simultaneously starts stable rigidity location, back; By the rotation of air valve seat 17, realize the break-make of the external main gas circuit of this device in addition with reel cage body 1.

Compared with prior art, the advantage of this invention 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 10 of this embodiment 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 straight pin 14 and rocking arm and base 10, and can rotate around bearing pin 15, connect with straight pin 11 between handle 18 and the reel cage body 1, and can rotate around straight pin 11, also be provided with two

straight pins

9 and 12 on the handle 18, wherein straight pin 12 is positioned at the track groove of shift fork 13, lean on the amplitude of fluctuation of the curve controlled shift fork 13 of track groove on the shift fork with the rotation of handle 18, realize control with this to gas valve core 16 positions, 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 enclosed stay 8 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 invention:

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 resorptions through tracheae 5, leakage display device 3, and the position that breaks away from gas valve core 16 also adjusted to shift fork 13 simultaneously by handle, and gas valve core 16 rises, air valve seat is communicated with air bag 19 inner chambers, gas enters into air bag 19 inner chambers, 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:

During work by the four-bar mechanism that constitutes between enclosed stay 8, handle 18, reel cage body 1 and the rocking arm and base 10, its bar length is respectively L1, L2, L3, L4, 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, when handle 18 begins to rotate, just can make shift fork 13 depress gas valve core 16, block air valve seat 17 cavity of resorptions, prevent that source of the gas gas from continuing to enter, and make air valve seat 17 epicoeles and atmosphere connect can, the gas of air bag 19 inner chambers 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 staies 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 straight pin 7 slips into the groove of enclosed stay 8 gabarits, obtain reliable rigidity location thus, be convenient to carry out the maintenance of various counter extensioin parts, remove the non-return handle 18 of depressing, otherwise can not remove.
