Description

Roller type reel cage

Technical field

The invention belongs to spinning machinery, relate to the innovation that improves the stressed stability of airload cradle, uniformity and the installation of raising reel cage, regulated efficiency.

Background technology

China's existing gas pressurization lever-type cradle is to domesticize and form on the DA2122P type reel cage basis of digesting and assimilating German INA company substantially.Its pressurization to jaw, by pressure transmission plate (2), power to be passed to pressure transmission main lever (3) by the air bag that is filled with certain pressure gas (1), power is passed to roller by pressure transmission main lever (3), power is passed to roller pin by roller, power is passed to handle (4) by roller pin, and handle (4) is passed to power by leverage that a set of like this mechanism of each upper and lower roller nip place completes again.Because pressure transmission link is many, and make the plus-pressure error between the each ingot of spinning machine of this class reel cage of current outfit larger, even if reach its error of national sector standard also up to 15%.This and cotton mill are expected to be not more than 5% requirement and are greatly differed from each other.The reason that between whole the each ingot of spinning machine, stressed inconsistency produces is that between the stressed unstability of reel cage itself and each reel cage, plus-pressure inconsistency causes jointly.In order to improve stressed uniformity between each ingot, must improve the stressed stability of single reel cage, also to there is a set of advanced person's the pressure fine-adjustment device can be by quick the pressure of each reel cage Correctly adjust unanimously simultaneously.With regard to a specific reel cage, its plus-pressure unstability, more than generally can reaching 10N, more than can reaching 20N on a small quantity.Through test and analysis, affect plus-pressure unstability, be mainly the nonconcentricity due to endoporus and the cylindrical of roller, then amplify through pressure transmission main lever (3), pressure transmission plate (2) is departed from due to nominal position.In the time again pressurizeing after reel cage release, because the circumferential position of roller cylindrical and the binding site of pressure transmission main lever (3) are random, roller is generally to be processed or powder metallurgy is made by conventional mechanical, therefore the concentricity of its inside and outside circle is not high enough, therefore after each pressurization, because the circumferential position of roller is not fixed and had again above-mentioned nonconcentricity, therefore its plus-pressure is just unstable.In order to improve the concentricity of roller, also after heat treatment to carry out multiple tracks grinding process in its roughing, this has just improved cost greatly.Again because its endoporus and cylindrical are not just grindings simultaneously of clamped one time, thus its nonconcentricity also can not eliminate completely, therefore grinding process is all reluctant to increase by general factory.So the plus-pressure unstability of this type of reel cage just seems too large at present.

With regard to whole spinning machine, because the transmission link of this type of Pendulum Weighting Arm System power is more, there is certain foozle in the part of each link, add the error of reel cage installation and reference for installation, make the decentralization of each Pendulum Weighting Arm System power on a spinning machine very large, and pressure micro-adjusting mechanism must be set.Now widely used this type of reel cage, substantially to copy the German INA DA2122P of company type reel cage as main.Its pressure fine setting and the installation of reel cage are fixed, and are to share (referring to " structural analysis of draft pressurizing cradle and use ", Tang Wenhui etc. write, Beijing China Textiles Press, in December, 2009, the 161st page and 214 pages) that a set of mechanism realizes.This often because mutually interfere and be difficult to accomplish to put in place simultaneously, must just may reach through repeated multiple times adjustment in the time of practical operation.Because its tubular axis is circular pipe, easily walk about and plus-pressure changed in long-term use location again.In addition, because the two ends system of its roller pin is riveted on handle and can not rotates, between it and roller, there is a little gap, its length of fit is longer again, and the dust of domestic spinning workshop, flyings are more, easily enter in above-mentioned gap, in the time that situation is serious, just may make roller stuck and do not turn, make reel cage resistance in the time adding release increase and cause handle to damage to reel cage is scrapped.This just has to the thickness of slab of handle is thick from the 1.5mm of DA2122P type reel cage, changes the thick the problems referred to above that solve of 2mm into, thereby increased cost after production domesticization.Although this type of reel cage has many good qualities, cause certain difficulty to for above-mentioned reasons the further popularization of such reel cage.And the reel cage that the domestic autonomous innovation patent No. is ZL200710009270.9 has been done a lot of improvement to its shortcoming, but still the plus-pressure that has a reel cage is stable not, owe simple when pressure fine setting, owe the deficiency such as convenient while installing.

Summary of the invention

The present invention is directed to the deficiencies in the prior art, a kind of improved gas pressurization lever-type cradle is provided.It both can increase substantially the stability of single Pendulum Weighting Arm System power, can reduce again manufacturing cost, can also make the installation of reel cage fixing independent separately with stressed micro-adjusting mechanism, make the installation of reel cage fixing more convenient, more reliable, make stressed fine setting more convenient, more accurate, thereby the plus-pressure uniformity of whole spinning machine is increased substantially, and can guarantee the design that plus-pressure is steady in a long-term constant.This scheme can meet cotton mill requirement well.

Technical solution of the present invention is this roller type reel cage that is applied to ring spinner, mainly comprise rocking arm and base (5), reel cage body (6), handle (4), gripping claw, leverage, four connecting rod pressurization retaining mechanisms, reel cage mechanism for installing, it is characterized in that: independently pressure fine-adjustment device is set in reel cage, this device makes and pressure transmission main lever (3) combination, plays the center of the roller bearing (7) of pressurization locking effect and can do appropriate variation with respect to rocking arm and base (5); Roller bearing (7) is axial workpiece, and its two ends can be overlapped separately to have or do not overlap roller bearing end cap (14) and be arranged on roller bearing frame (13) or handle (4); It is upper that rocking arm and base (5) is fixed on a tubular axis (8), fixing rear its invariant position.

The scheme that makes the center of roller bearing (7) can do appropriate variation with respect to rocking arm and base (5) is a lot, as arranged and contain screw-nut, eccentric shaft, rack-and-pinion, cam in device ... drive mechanism, suitably regulates these structures to achieve the above object.But, in pressure fine-adjustment device independently, at least arrange and contain pressure regulating screw (17) or look nut (19), can do to change in right amount with respect to rocking arm and base (5) with the center that regulates above-mentioned screw or nut to reach to make roller bearing (7) is the scheme of simple.

Because roller bearing (7) only needs clamped one time just can complete fast whole processing for axial workpiece in manufacture process, therefore the concentricity between its each cylindrical section is just easy to the level that reaches high, replace the structure originally be made up of roller and roller pin just can make the plus-pressure stability of reel cage greatly improve with roller bearing (7), the while can also be reduced manufacturing cost.

In order to make reel cage upper fixing more reliable at a tubular axis (8), a tubular axis (8) can be selected polygon pipe or special pipe.In order to make reel cage more convenient, quicker in the upper handling of a tubular axis (8), can will originally be fixed in the structure on a tubular axis (8) by upper rocking arm and base (5) and bottom cradle seat by the screw at two ends, change the structure with clamping seats (9) by rocking arm and base (5) into.Clamping seats (9) is designed to hinge with one end of rocking arm and base (5) and is connect structure, and the other end adopts the structure of nut (10) and anti-turn screw (11) composition.

Advantage of the present invention and good effect are: can make whole the stressed uniformity of spinning machine, stability increase substantially and can guarantee steady in a long-term constant.Make reel cage installation, adjust more fast, more accurate, provide strong guarantee thereby the ingot when reducing to spin is poor and improve yarn count quality.And the enterprise that can make to spin improves work efficiency, reduces recruitment, enhances one's market competitiveness.

Detailed description of the invention

Example 11,2,3,4,5,6,7,8 is described as follows by reference to the accompanying drawings:

To be fixed on handle originally and overlap this section of handle that has the roller pin of roller and be used for fixing roller pin and together remove, replace roller and roller pin be contained on roller bearing frame (13) with roller bearing (7), roller bearing frame hinge is associated on handle with pin, then the part such as pressure regulating screw (17), look nut (19) is set just forms independently pressure fine-adjustment device.

Independently pressure fine-adjustment device of basis as from the foregoing, mainly be made up of roller bearing frame (13), handle (4), roller bearing (7), pressure regulating screw (17), look nut (19), roller bearing frame (13) is associated on handle (4) by handle roller bearing frame pin (18) hinge.

Fine setting about pressure: reel cage is placed in to pressurized state, in the time finding that the plus-pressure of certain reel cage is less than setting value, available plank turns pressure regulating screw (17), roller bearing frame (13) is counterclockwise suitably swung by diagram centered by handle roller bearing frame pin (18), and the roller bearing (7) being at this moment contained on roller bearing frame (13) just forces pressure transmission main lever (3) to do in the direction of the clock appropriate swing centered by being fixed on the pressure transmission main lever point pin (12) on rocking arm and base (5).Pressure transmission main lever (3) just presses down past air bag (1) by pressure transmission plate (2), cause air bag (1) to increase the active force of pressure transmission main lever (3), thereby the plus-pressure of this reel cage is increased, until reach predetermined plus-pressure.If find, the plus-pressure of certain reel cage is bigger than normal, and the way of available above-mentioned reverse adjustment reduces plus-pressure, until reach predetermined plus-pressure.Between roller bearing frame (13) and handle (4), be provided with board-like Compress Spring (22), can produce to (13) clockwise active forces of roller bearing frame, make pressure regulating screw (17) all the time in tension.Look nut (19) is self-locking nut, adopting this nut to lock facilitates manyly than traditional locking ways such as double nut locking, two screw lock, only need an action just can complete pressure regulation and locking by this way, and at least needing three actions just can complete by other conventional approach, this significantly improves regulated efficiency.

Installation about reel cage is fixed: when unscrewing after nut (10), anti-turn screw (11) can be made left and right pendulum, in the time that it is flapped toward right side, clamping seats (9) just can clockwise rotate centered by the hingle shaft in left side, clamping seats (9) is opened, at this moment just reel cage can be contained on a tubular axis (8), then by for counterclockwise rotation clamping seats (9), make clamping seats (9) and tubular axis (8) combination, again anti-turn screw (11) is swung and is placed in the groove of clamping seats (9) left, fastening nut (10) again, the installation of reel cage is just fixed and has been accused, rocking arm and base (5) has also just maintained static simultaneously.

Assembling about roller bearing (7): if when roller bearing (7) is greater than the axial workpiece of the one end in two ends for stage casing diameter, available conventional way packs into, and when roller bearing (7) stage casing diameter is large, two ends diameter is little, situation under, cannot pack roller bearing frame (13) into by conventional way.But because roller bearing frame (13) is thin-walled metal sheet, in the time its two riser being expanded outwardly by a suitable power, roller bearing frame (13) lower end just can expand outward, at this moment just roller bearing (7) can be packed into from inside, two axle journals of roller bearing (7) are packed in the two side holes of roller bearing frame (13).Because removing after external force, roller bearing frame (13) can there is some residual deformations, make its lower end can not recover original width, at this moment can be bumped into spacing part (15), rivetted again, so just can be guaranteed the constant rigidity that simultaneously also increases roller bearing frame (13) of roller bearing frame lower end width.For two axle journals of roller bearing (7) are packed in the respective aperture of roller bearing frame (13) more easily, the short transverse in this hole can be designed to be slightly larger than the slotted hole of width.

Roller bearing (7) is contained in to way on roller bearing frame (13) except roller bearing frame (13) two riser lower ends are magnified from inner side packs into, can also be diversified.Be exemplified below:

As shown in Figure 3, roller bearing (7) packs into from roller bearing frame (13) right side, for preventing that roller bearing (7) from skidding off, can fill a circlip at the small end of roller bearing (7).In order to strengthen the rigidity of roller bearing frame (13), can set up girth member (16) thereon and its two ends are rivetted or are welded.

As shown in Figure 4, roller bearing (7) packs into from roller bearing frame (13) one sides, be loaded on roller bearing end cap (14) and it is welded on to roller bearing frame (13) upper, equally with upper example can set up girth member (16).Roller bearing end cap (14) also can be made various shape, is exactly an example as shown in Figure 8.

As shown in Fig. 5,6,7, roller bearing (7) packs into from roller bearing frame (13) one sides, be loaded on roller bearing end cap (14), its end cap groove (20) coordinates and rivets or be welded with the local flange (21) of roller bearing frame (13), also can set up girth member (16) the same as upper example.

Girth member (16) can be pin, can be also rivet, can be also lath.And it and roller bearing frame (13) is fixing except riveted joint, it can be also welding.

The hole place that roller bearing frame (13) coordinates with roller bearing, can be provided with flange, can suitably increase and the length of fit of roller bearing axle journal, also can not establish.

Example 29,10 is described as follows by reference to the accompanying drawings: this example is basic identical with example 1, and its pressure fine-adjustment device is mainly also made up of roller bearing frame (13), roller bearing (7), pressure regulating screw (17), look nut (19), handle (4) (not removing that section of fixing former roller pin).Example 1 is to make roller bearing frame (13) do appropriate swing to realize pressure fine setting, and this example is to make roller bearing frame (13) suitably move and realize fine setting upper work of handle (4).Guarantee that in order to make the track consistent (displacement and direction can be inconsistent) of above-mentioned each movement pressure regulation is stable, two groups of group holes of containing slotted hole can be at least set between roller bearing frame (13) and handle (4), first group of hole coordinates with reel cage body pin (25), handle (4) is upper is circular hole, and roller bearing frame (13) is upper is slotted hole; Second group of hole coordinates with roller bearing (7) (or containing roller bearing end cap), handle (4) is upper is slotted hole, roller bearing frame (13) is above circular hole or coordinates with girth member (16), handle (4) is upper is the hole identical with girth member (16) section, and roller bearing frame (13) is upper is slotted hole; Or there are above-mentioned three combinations simultaneously.

Figure 9 shows that the above-mentioned scheme with three groups of holes, the slotted hole in three groups of holes and be mated part and coordinate, just can make the track maintenance of roller bearing frame (13) when appropriate mobile stablize and leave mobile space.In the time that finely tuning, pressure should turn look nut (19), now pressure regulating screw (17) just moves with respect to handle (4) in right amount with roller bearing frame (13) and roller bearing (7) disposed thereon, makes pressure transmission main lever (3) do corresponding swing.The object that also can reach pressure fine setting the same as example 1, handle (4) is motionless with respect to rocking arm and base (5) in the time that pressure is finely tuned.

While removing as seen from the figure the slotted hole in arbitrary group of hole in above-mentioned second group of hole, (make the material at slotted hole place as removed or do not establish girth member), also can make roller bearing frame (13) do appropriate movement with respect to handle (4) time, guarantee mobile stablizing, equally also can realize reliable pressure fine setting.Fix and to be contained in way on roller bearing frame (13) about roller bearing (7) all identical with example 1 about the installation of reel cage.

Also pressure regulating screw (17) can be turned around in this example to install, look nut (19) is just correspondingly set on roller bearing frame (13) inner chamber, should turn pressure regulating screw (17) in the time that pressure is finely tuned.

Example 3 11 is described as follows by reference to the accompanying drawings: this example is basic identical with example 2, its difference is that pressure fine-adjustment device is mainly made up of pressure regulation frame (23), handle (4), pressure regulating screw (17), roller bearing (7), and two groups of holes containing slotted hole are set between pressure regulation frame (23) and handle (4); First group of hole coordinates with reel cage body pin (25), and handle (4) is upper is slotted hole, and pressure regulation frame (23) is upper is circular hole; Second group of hole coordinates with roller bearing (7) (or containing roller bearing end cap), and handle (4) is upper is circular hole, and pressure regulation frame (23) is upper is slotted hole.

Finely tune about pressure: in the time finding that certain Pendulum Weighting Arm System power is on the low side, can turn pressure regulating screw (17) makes it suitably downward, because pressure regulating screw (17) withstands on pressure regulation frame (23) above, pressure regulation frame (23) is that circular hole coordinates with reel cage body pin (25), therefore pressure regulation frame (23) can not move down, handle (4) is that slotted hole coordinates with reel cage body pin (25), this just forces handle (4) correspondingly upwards to do appropriate variation with roller bearing (7) (or containing roller bearing end cap) along above-mentioned slotted hole direction, thereby the pressure of this reel cage is increased.While turning on the contrary pressure regulating screw (17), between pressure regulating screw (17) and pressure regulation frame (23), should there is gap, because reel cage pressure transmission main lever (3) under pressurized state has a downward active force all the time to roller bearing (7), and roller bearing (7) and handle (4) coordinate for circular hole, this just forces roller bearing (7) to do corresponding variation downwards with handle (4), thereby the plus-pressure of this reel cage is reduced, equally also can reach the object of pressure fine setting.

Locking pad (24) has certain flexible material by plastic cement, rubber-like to be made, and is provided with the effect that just can reach locking that coordinates of suitable interference with pressure regulating screw (17).Also can establish a nut in the head of screw below of pressure regulating screw (17) comes locking.

Directly make screw thread upper at handle (4) and that pressure regulating screw (17) matches, also can directly use nut, then be fixed on handle (4).

Assembling way about roller bearing (7) on handle (4), basic identical with example 1, its difference is that example 1 is that roller bearing (7) is contained in to roller bearing frame (13) above, and this example is that roller bearing (7) is contained on handle (4).

Installation about reel cage is fixed, identical with example 1.
