Description
The utility model relates to the direct-type air bag that adopts in the textile industry spinning machinery drafting system gentle locking reel cage that pressurizes, and is particularly useful for the spinning, drawing process of ring spinning frame.
Spinning machineries such as drawing frame, Speed frames, ring spinning frame adopt several pressurization roller and roller mechanisms to friction speed that processed fibrous material is gripped and tractive usually, realize drafting process.In order to spin fibres such as uniform strip, rove, spun yarn, the reel cage in the drafting system must apply certain satisfactory pressure to each roller, controls the motion of processed fiber, guarantees that the bar evenness of fibre reaches requirement.With used drafting system on the ring spinning frame, existing pneumatic pressurizing cradle is comparatively advanced German Yi Na (INA-V type) drawing-off reel cage, 88304141.X Chinese patent, 98225203.X Chinese patent; 00217413.8 number patent application then provides a kind of pneuma-lock reel cage.
Germany Yi Na drafting system adopts the reel cage of air bag or cylinder pressurization.During work, compressed air enters air bag or cylinder, and roller was realized the roller pressurization before, during and after the pressure of generation arrived pressure distribution by one group of interlock lever.This drafting system compression motion speed is fast, installs simply relatively, and management and maintenance is easy, and is strong to ambient temperature and humidity adaptability; But when spinning different cultivars, different fineness spun yarn, spacing between required pressure of each roller and roller has nothing in common with each other, this arm of force that need regulate relevant interlock lever is realized, reaches consistent but such adjusting can not guarantee every suit drafting system, causes the bar evenness that spins yarn inconsistent.
88304141.X the characteristics of number disclosed pneumatic pressurizing cradle of Chinese patent are, the cylinder and the gas that be provided with that several groups of relative pressures are stable, internal diameter size and sectional area vary in size distribute the conducting connecting rod to form moving system, respectively to corresponding roller pressurization, to guarantee that roller is applied stable and satisfactory pressure, mechanism is relatively complicated.
98225203.X number Chinese patent is disclosed also to be the cylinder pressurized cradle, structure is more complicated also.
00217413.8 the characteristics of the pneuma-lock reel cage that number patent application proposes are, rocking arm and base is enclosed within on the reel cage support, both are fixed by lock-screw, reel cage fulcrum upper end has groove, establish the gas circuit pipe that runs through complete machine length in the groove, gas circuit pipe and exhaust hood UNICOM, the valve of control gas path on-off is established in the connection position, utilizes the break-make of the gas circuit that adds air cylinder of reel cage to realize the locking and the unlatching of reel cage and spinning machine.
The purpose of this utility model is above existing reel cage to be made improvements perfect, designs a kind of direct-type air bag gentle locking reel cage that pressurizes.
The rocking arm and base that the utility model comprises the reel cage shell, be connected with the reel cage shell by rotating shaft, supporting rocking arm and base and by the fixing reel cage axle of bolt and spinning machine main frame, the roller etc. that pressurizes, its primary structure feature is as follows.Its pressures partially comprises air bag and the bearing thereof that is connected with the compressed air source air inlet pipe and directly is arranged at the reel cage enclosure, amount to the preceding middle rear leather roller seat that the limit is screwed with the reel cage outer casing underpart, rear leather roller seat and top and air bag bottom directly contacts in before passing preceding in the back depression bar, directly push down respectively bottom the depression bar of middle back middle after the roller axle; The forward press bottom then contacts with the rocking arm top, and rocking arm and front leather roller seat link into an integrated entity, and the front leather roller axle is then pushed down in the rocking arm bottom.
Lock portion is characterised in that and comprises: a J-shaped latch hook that is enclosed within the rotating shaft that connects reel cage shell and rocking arm and base, the lock pin that is fixed on the rocking arm and base is hooked at the hook position of J-shaped latch hook, the bottom of J-shaped latch hook then is provided with retainer spring, a reverse side of the top of J-shaped latch hook, latch hook hook then be positioned at reel cage shell top on the plush copper of pull bar contact; Also be provided with the valve pull bar that to block the air bag gas circuit on the top of reel cage shell; The rear portion of reel cage also is provided with an end and relies on rocking arm and base, the other end and rely on the reel cage outer casing top surface and have the upwards torsion spring of thrust.
The direct-type air bag of said structure pressurize gentle locking reel cage by the air bag that is positioned at the reel cage shell directly to before, during and after roller pressure rod pressurization, can guarantee that pressurization is consistent, the roller spacer is easy to adjust, does not need during installation to adjust one by one, leaks gas and lacks.
Accompanying drawing 1 is the utility model structural representation.Among the figure:
1. air bag; 2. front leather roller seat; 3. medium rubber roller seat; 4. rear leather roller seat; 5. air bag bearing; 6. forward press; 7. middle depression bar; 8. depression bar after; 9. rocking arm; 10. air inlet pipe; 11. rocking arm and base; 12. reel cage axle; 13. alignment pin; 14. reel cage shell; 15. valve pull bar; 16. torsion spring; 17. lock pin; 18. lock-screw; 19. pull bar; 20.J shape latch hook; 21. valve; 22.J shape latch hook retainer spring; 23. connect the rotating shaft of reel cage shell and rocking arm and base.
Below the utility model is described in further detail.
During pressurization, be contained in air bag 1 in the reel cage shell 14 after air inlet pipe 10 inflations, before air bag 1 promotes in 6,7,8 pressurizations of back depression bar, the pressurization size is determined by depression bar top and air bag 1 contact-making surface size.The fixed-site of front leather roller seat 2, in, rear leather roller seat 3,4 can move forward and backward along reel cage shell 14, and by trip bolt 18 the 2mm of reel cage shell 14 bottoms wide amount on the limit fixing.In have elongated slot in the middle of the rear leather roller seat 3,4, and the protrusion position with described elongated slot coupling is arranged at the top of middle back depression bar 7,8, protrude the position insert in the middle of the rear leather roller seat 2,3 in the elongated slots, in making, back depression bar 7,8 can only move up and down and can not move forward and backward.Front leather roller seat 2 is connected as a single entity with rocking arm 9 and forward press 6.
The action principle of lock portion is as follows.Under the air bag 1 inflation pressurized state, J-shaped type latch hook 20 hooks lock pin 17, thus reel cage shell 14 can't on lift and be locked, and J-shaped latch hook 20 is subjected to the effect of retainer spring 22 can not throw off lock pin 17 again.During release, pull valve pull bar 15, valve 21 cuts off gas circuit, pull bar 19 is pulled in the roller release simultaneously, and the plush copper of pull bar 19 promotes the top of J-shaped latch hook 20, make J-shaped latch hook 20 overcome the pressure of retainer spring 22 and break away from lock pin 17, reel cage shell 14 is being lifted on automatically under the thrust of torsion spring 16.When locking, depress reel cage shell 14 in the time of pulling pull bar 19, under retainer spring 22 effects, J-shaped latch hook 20 enters lock pin 17 automatically; Pulling valve pull bar 15, gas circuit is connected, and reel cage is in running order once more.
