Abstract
A pressurizing and holding device of a direct-typed pneumatic pressurizing cradle applied to a spinning machine in the textile industry comprises a cradle shell and an air cylinder or an air bag arranged inside the shell. The utility model is characterized in that the device also comprises a leather-roller seat that can move along the cradle shell and can be fixed on the shell, a pressurizing rod with the upper end part passing through the upper end of the leather-roller seat and being directly contacted with the air cylinder or the air bag and with the lower end directly acting on a leather roller, a spring retainer that is fixed on the leather-roller seat and is used for holding the leather roller, and a bolt and a nut which are used to fix the leather-roller seat. The device has the advantages that the structure is simple, the pressure application is correct and uniform, and the pressure-distribution deviation among all ingots of the whole device is small. Since the pressurizing rod only plays the role of pressurizing, and the leather-roller seat only plays the role of holding the leather roller and guaranteeing the parallelism, and the influence caused by the elements such as the forward-rushing of the leather roller on the pressurizing process can be prevented.
Description
1. technical field
The utility model relates to pneumatic pressurization of direct-type and the grip device that the spinning machinery drafting system adopts in a kind of production of weaving, and mainly is applicable to Speed frames and ring spinning frame.
2. background technology
Spinning machinery such as Speed frames, ring spinning frame all adopts several pressurization roller and roller mechanisms to friction speed that processed fibrous material is gripped and tractive, realizes drafting process.Pressurized cradle in the drafting system must apply certain satisfactory pressure to each roller, and to control the motion of processed fiber, fibre bars such as the rove that assurance spins out, spun yarn are done evenly.The comparatively advanced cylinder or the pneumatic pressurizing cradle of air bag form have been adopted at present on Speed frames and the ring spinning frame, as German Yi Na (INA-V type) drawing-off reel cage, Chinese patent 88304141.X, 98225203.X cylinder pressurized cradle, 00217413.8 the air bag of number Chinese patent locking reel cage etc., but there are problems such as mechanism's complexity, the pressurization uniformity be inconsistent mostly.
00249418.3 the structural feature of Chinese patent " the direct-type air bag of spinning machinery pressurize gentle locking reel cage " is to be provided with air bag (referring to Fig. 1) in the reel cage shell, and rear leather roller seat and top and air bag bottom directly contact in before passing preceding middle after depression bar, airbag aeration pusher dynamic pressure bar is realized the pressurization to roller respectively by rocking arm or self push down the roller axle.Shortcoming is a complex structure, and it is inhomogeneous to pressurize.The reverse component of roller that the preshoot of roller etc. causes acts on pressure rod, and pressure rod is deflected, and produces friction with roller, causes output pressure difference; The control depth of parallelism requires the accuracy of manufacture height of part, processed complex.
3. summary of the invention
The utility model is made architecture advances at the defective of No. 00249418.3 Chinese patent, sets up simple in structure, pressurization uniform direct-type pneumatic pressurizing cradle and a grip device.
Direct-type pneumatic pressurizing cradle and grip device that the utility model provides comprise the reel cage housing, the cylinder or the air bag that be located in the housing, are connected with compressed gas source, it is characterized in that also being provided with and to move and to be fixed on leather roller seat on the housing along the reel cage housing, the upper end pass top on the leather roller seat and directly contact with cylinder or air bag, pressure rod that the lower end then directly acts on the roller axle, be fixed on the leather roller seat, the spring jump ring of clamping roller, the fixedly screw bolt and nut of leather roller seat.
The utility model has the advantages that simple in structurely, exert pressure accurately, evenly that the pressure distribution error is little between each ingot of complete machine.Because the pressure rod of this device only plays pressurization, leather roller seat only plays and grips roller and guarantee depth of parallelism effect, so the reverse component of roller that is caused by the roller preshoot acts on leather roller seat and is delivered on the housing, has avoided the influence to pressurization.
4. description of drawings
Accompanying drawing 1 is the structural representation of 00249418.3 Chinese patent " the direct-type air bag of spinning machinery pressurize gentle locking reel cage "; Organigram when accompanying drawing 2 adopts air bag for the utility model; Fig. 3 is the A-A profile of Fig. 2.
Among Fig. 2 and Fig. 3: 1. reel cage housing; 2. air bag; 3. pressure rod; 4. leather roller seat; 5. spring jump ring; 6. ring flange nut; 7. half-round head square neck bolt; 8. pan head screw; 9. roller.
5. the specific embodiment
The main distinction of the reel cage structure of the utility model and No. 00249418.3 Chinese patent proposition is: 3 of pressure rods play pressurizations (Fig. 2), leather roller seat 4 grips roller 9, the depth of parallelism of roller 9 is guaranteed by the machining accuracy of leather roller seat 4, and is better than Chinese patent No. 00249418.3.
As shown in Figure 2: start working after being contained in power source air bag 2 inflations in the reel cage housing 1, make the upper end of pressure rod 3 stressed, pressure rod 3 passes leather roller seat 4 and moves downward along guide groove, the lower surface directly withstands on the roller axle, therefore, the pressure that is produced by air bag 2 acts directly on the roller axle by pressure rod 3, and to roller 9 pressurizations, roller 9 grips sliver realization drawing-off jointly with corresponding roller.The U type groove of leather roller seat 4 is used to grip the roller axle, promptly is the locating slot that guarantees the roller depth of parallelism, and its positioning accuracy is guaranteed by processing technology.The roller axle can move up and down in U type groove, to transmit different pressure by pressure rod 3.When reel cage is opened, do not deviate from U type groove, spring jump ring 5 clamping roller axles are housed in the both sides of leather roller seat 4, make the unlatching associated movement of roller 9 with reel cage for making the roller axle.Leather roller seat 4 both sides have groove, therefore can move forward and backward along the slideway on reel cage housing 1 base, so that require adjustment to space according to the different yarns kind, adjust the back and are fixed tightly on the reel cage housing 1 by semicircle square neck bolt 7 and ring flange nut 6.
When power source adopted cylinder to replace air bag, only the power source form changed, and described pressure rod 3 plays pressurization with the form of cylinder piston rod, and the structure of all the other each mechanisms and action are identical during with the employing air bag.
Claims (3)
1. the pressurization of direct-type pneumatic pressurizing cradle and grip device, comprise reel cage housing 1, the cylinder or the air bag 2 that be located in the housing 1, are connected with compressed gas source, it is characterized in that also being provided with and to move and to be fixed on leather roller seat 4 on the housing 1 along reel cage housing 1, the pressure rod 3 that the upper end is passed top on the leather roller seat 4 and directly contacted with cylinder or air bag 2, be fixed on the leather roller seat 4, the spring jump ring 5 of clamping roller 9, the fixedly bolt 7 of leather roller seat and nut 6, the lower end of pressure rod 3 directly acts on the roller axle.
