The combing machine is a device widely used in carding step, and it is used to comb the fiber bundle, remove the short fiber in the fiber bundle, cut off the cross connection between fibers, and strengthen the longitudinal connection between fibers.

The cotton roll is placed on a pair of roll-bearing rollers, and the cotton layer is unwound with the rotation of the roll-bearing rollers, and the unwound cotton layer can be guided by the roll-guiding plate or directly conveyed by the cotton-feeding roller positioned on the nipper. The cotton feeding roller periodically and intermittently rotates, a cotton layer with a certain length is fed into a jaw formed by an upper nipper and a lower nipper each time, the nippers periodically swing back and forth, the jaw is closed midway along the back swing, and the cotton layer is powerfully clamped, so that the cotton layer outside the jaw is in a suspension state. At the moment, the card wire surface on the cylinder just runs to the lower part of the jaw, and the pin teeth are inserted into the cotton layer for carding to remove short fibers, impurities and defects in the cotton layer. As the cylinder card face rotates to the lower position, short fibers, defects and the like embedded between the pin teeth are removed by the brush rotating at a high speed, and the combed cotton layer is led out at a separation roller.

However, the existing nipper type combing machine has certain defects to be improved: 1. the length of the needle teeth on the cylinder of the existing nipper type combing machine cannot be adjusted, so that the existing nipper type combing machine can only comb raw materials with one fiber length, and the universality is poor. 2. The existing combing machine generally comprises a plurality of combing units, and cylinder barrels of the combing units are connected through a special coupling; however, the shaft couplings used among the cylinder barrels of the combing units in the prior art have the problems of complex structure, large processing difficulty and high manufacturing cost; or poor connection performance and poor stability. 3. In the carding process of the existing combing machine, static electricity is easily accumulated in the carding process due to over-drying of a cotton layer, so that the combing process is not favorable for straightening fibers, and the separating and removing effect of short fibers is influenced.

Detailed Description

A spinning machine with high stability, as shown in FIGS. 1-9, comprises a frame and a feeding mechanism, a carding mechanism and a delivery mechanism arranged on the frame, wherein the frame, the feeding mechanism, the carding mechanism and the delivery mechanism are substantially the same as those of the prior nipper type combing machine, and the invention is not explained in detail in the text of the specification for saving space and saving space in the prior art. Generally, the feeding mechanism comprises a roll-supporting roller 1 and a cotton feeding roller 2, the carding mechanism comprises a nipper component 3 and a cylinder 4, and the output mechanism comprises two groups of separating rollers 5. Compared with the prior nipper type combing machine, the invention mainly comprises three major points, 1, and the improvement of a cylinder card needle part; 2. the improvement of the connection mode between the cylinders; 3. and the surface layer 0 is improved by humidifying before entering the carding mechanism. The improvements in the three aspects can be applied independently to a conventional combing machine, although alternatively two or all of them can be applied to a combing machine.

With respect to the first great difference, as shown in fig. 2 and 3, the cylinder 4 includes a drum 8, a carding assembly, which is a main working part of carding cotton flocks, mounted on the drum 8, and a counter weight assembly, which periodically combs cotton flocks held by the nipper assemblies 3 as the drum 8 rotates. The counterweight assembly is used for being arranged at the opposite side of the cotton carding assembly to balance the weight and prevent the rotary drum 8 from vibrating due to overlarge eccentricity. Therefore, the cotton carding assembly and the counterweight assembly of the invention are both installed on the circumferential surface of the rotary drum 8 and are oppositely arranged by taking the axis of the rotary drum 8 as the center. As shown in connection with fig. 5 and 6, the cotton comb assembly includes a mounting box 6 and an adjusting plate 7. The mounting box 6 is provided on the circumferential surface of the drum 8, and the mounting box 6 is in a rectangular parallelepiped shape with an open top surface and extends in the longitudinal direction of the drum 8. The top surface of the mounting box 6 is the surface of the mounting box 6 away from the rotary drum 8, and the bottom surface of the mounting box 6 is the surface of the mounting box 6 close to the rotary drum 8.

All be provided with a plurality of bar mouths 9 on the lateral wall of the mounting box 6 left and right sides, bar mouth 9 is played by the top of the 6 lateral walls of mounting box and is followed vertical extension down, the shape and the size of regulating plate 7 and the inner chamber looks adaptation of mounting box 6 can slide in the inner chamber of mounting box 6. Of course, in order to further ensure the sliding stability of the adjusting plate 7, it is preferable that a plurality of vertical guide rods 22 are fixedly disposed on the inner wall of the bottom surface of the mounting box 6, a plurality of guide holes matched with the guide rods 22 are disposed on the adjusting plate 7 corresponding to the guide rods 22, and the guide rods 22 are inserted into the guide holes. The guide bar 22 is capable of providing excellent positioning and guiding of the adjusting plate 7, said guide bar 22 being generally circular, but preferably the guide bar 22 is square. The position and the number of the edges of the left side and the right side of the adjusting plate 7 corresponding to the strip-shaped openings 9 are provided with a plurality of short studs 10, and locking nuts 11 are adapted on the short studs 10. Short stud 10 wears to establish in bar mouth 9, regulating plate 7 passes through lock nut 11 and locks on the wall of the mounting box 6 left and right sides to realize regulation and fixed. A plurality of comb pins 50 are fixedly arranged on the adjusting plate 7.

The carding needle 50 of the invention is arranged on the adjusting plate 7, and carding is mainly carried out on cotton flocks by utilizing a section of the carding needle 50 which exceeds the top of the mounting box 6. When carding of cotton clumps of different thickness, in fact raw materials of different fiber lengths, is required, the adjusting plate 7 can be adjusted along the length direction of the strip-shaped opening 9 by first unscrewing the lock nut 11, and the length of the strip-shaped opening 9 substantially performs the adjustment range of the carding wire 50. But bar mouth 9 symmetric distribution on the lateral wall of mounting box 6 both sides, but better practice is, is located the bar mouth 9 of the mounting box 6 left and right sides is crisscross each other, also is bar mouth 9 on the wall of mounting box 6 left side and the bar mouth 9 on the wall of right side stagger each other to can promote regulating plate 7 and lock the stability when nut 11 is fixed. The invention can change the height of the carding wire 50 exceeding the top surface of the mounting box 6 according to the thickness of the raw material cotton layer 0, as shown in fig. 5 and 6, when needing to comb the cotton clump with larger thickness, the extending length of the carding wire 50 should be lengthened. In most cases, the height of the comb 50 above the adjusting plate 7 is 10-15CM, and the length of the strip-shaped opening 9 is 5-10 CM. After the adjusting plate is adjusted in place, the adjusting plate 7 and the mounting box 6 are locked by the locking nut 11. Compared with the traditional cylinder 4 structure of the combing machine, the invention can adapt to various raw materials with different cotton layer 0 thicknesses, has stronger universality and simple structure, and is convenient to process and produce.

The card wire 50 of the present invention may be in the form of a conventional straight wire body, but in order to improve the carding effect, it is preferable that the top end of the card wire 50 is bent to form the hook 12, and the bending direction of the hook 12 is the same as the rotation direction of the drum 8. When the card wire 50 contacts with the cotton cluster, the hook part 12 has a certain pulling force to the fiber of the cotton cluster, thereby the carding effect is better, and the separation rate of the short fiber can be increased. For the raw material with a large thickness of the cotton clump, because the card wire 50 is subjected to a larger resistance in the process of contacting with the fiber, if a conventional card wire is adopted, on one hand, the card wire is easy to damage itself in the process of long-term use, and on the other hand, the excessive rigidity is easy to damage the fiber. To this end, the present invention further improves the card wire 50, and as shown in fig. 7, a section of the card wire 50 near the bottom end is bent in an S-shape to form the buffer 13. The arrangement of the buffer part 13 ensures the strength of the card wire 50, so that the card wire 50 has certain flexibility, the service life of the card wire is prolonged, the maintenance cost is reduced, and the fiber damage is avoided.

Generally, the lower end of the comb 50 is welded directly to the adjusting plate 7 to be fixed, but this way, the stability of the comb 50 is poor, and the welding surface is narrow, which is inconvenient to weld. Therefore, the adjusting plate 7 of the invention is provided with a plurality of pin blind holes corresponding to the number of the comb pins 50, and one side of the comb pins 50 close to the bottom end and back to the hook part 12 is fixedly provided with a triangular reinforcing piece 14. The distance between the lower edge of the triangular reinforcing piece 14 and the bottom end of the comb pin 50 is equal to the length of the blind pin hole. The bottom end of the comb pin 50 is inserted into the pin blind hole, and the bottom end of the comb pin 50 and the lower edge of the triangular reinforcing piece 14 are welded with the adjusting plate 7. In this way, because there is a section of the comb 50 in the blind hole of the pin, the comb 50 and the adjusting plate 7 have better combination. Meanwhile, the triangular reinforcing pieces 14 also play a role of auxiliary support to prevent the comb pins 50 from being deformed. It should be noted, however, that the triangular reinforcing plate 14 should be positioned opposite to the bending direction of the hook 12 during welding, i.e., opposite to the rotation direction of the drum 8. Practice proves that the triangular reinforcing plate 14 has a very special effect besides the above-mentioned effects, and the triangular reinforcing plate 14 can effectively prevent short fibers, impurities and the like from winding and depositing at the root of the comb needle 50 due to the partition effect, so that the short fibers and the like can be conveniently removed by subsequent brushes.

Regarding the installation of the installation box 6 and the rotary drum 8, generally, it can be welded directly on the rotary drum 8 or cast integrally with the rotary drum 8, but the installation box 6 of the first method cannot be detached, is inconvenient to maintain, and the second method is relatively complex to process. For this purpose, it is also preferable that, as shown in fig. 2 and 4, two installation planes extending in the length direction of the drum 8 are symmetrically arranged on the circumferential surface of the drum 8 with respect to the axis of the drum 8, and the cotton comb assembly and the weight assembly are respectively located at the two installation planes. The bottom surface of the mounting box 6 is matched with the mounting plane and is placed on the mounting plane, the placement essentially means that the bottom surface of the mounting box 6 is contacted with the mounting plane, and the bottoms of the left side and the right side of the mounting box 6 are provided with arc-shaped plates 15 matched with the radian of the circumferential surface of the rotary drum 8. The arc-shaped plate 15 extends along the length direction of the rotary drum 8 and is fixedly connected with the rotary drum 8 through a first connecting bolt 16. After the arrangement, the mounting box 6 can be quickly and integrally taken down, so that the maintenance is convenient. On the other hand, the mounting plane plays a role in positioning and limiting the mounting box 6, and the mounting box 6 can be effectively prevented from moving. In addition, in order to prevent the mounting box 6 from being axially dislocated along the rotary drum 8, the front end surface and the rear end surface of the mounting box 6 of the invention extend downwards to form an axial limiting plate 17, and the axial limiting plate 17 is fixedly connected with the end surface of the rotary drum 8 through a second connecting bolt 18.

In the adjusting process of the adjusting plate 7 and the comb pins 50 on the rotary drum 8, when the extension length of the comb pins 50 is changed, the total gravity center of the cylinder 4 is in continuous shift, and for this reason, in order to reduce the shaking of the cylinder 4, the counterweight assembly of the invention should also be adjustable, as shown in fig. 2 and 4, and the counterweight assembly comprises a counterweight plate 19, a mounting screw rod 20 and a bearing nut 21. And a plurality of mounting screws 20 vertical to the mounting plane are arranged on the mounting plane of the rotary drum 8 far away from the cotton carding assembly. The mounting screws 20 are symmetrically and uniformly distributed on two sides of the mounting plane, and two bearing nuts 21 are adapted to each mounting screw 20. The weight plate 19 is a rectangle extending along the length direction of the rotary drum 8, a plurality of rod holes matched with the installation screw rods 20 are correspondingly arranged on the left side and the right side of the weight plate 19, the installation screw rods 20 are arranged in the rod holes in a penetrating mode, and the weight plate 19 is clamped between the bearing nuts 21. After adopting such a mode, can change the skew mounting plane's of counter weight plate 19 distance through bearing nut 21, and then with the regulating variable who matches gill pin 50, make the overall balance of cylinder 4 better, alleviated the shake phenomenon of cylinder 4. In order to improve the clamping force of the bearing nut 21 on the counterweight plate 19, a rubber gasket is arranged between the bearing nut 21 and the counterweight plate 19 in the invention, and the rubber gasket is sleeved on the mounting screw rod 20.

The second great difference with respect to the present invention, as shown in fig. 2, 3 and 8, is mainly that: the carding mechanism is characterized in that a plurality of groups of carding mechanisms are arranged on the rack along the width direction of the rack, the structure is simple, the carding mechanism is not shown in the figure, and connecting shafts are arranged on two end faces of a cylinder 4 of the carding mechanism. That is, as shown in the cylinder 4 of fig. 3, a plurality of cylinders 4 are arranged in order in the left-right direction, and the cylinders 4 of two adjacent sets of carding mechanisms are connected to each other by a connecting shaft. The connecting shaft comprises a bearing mounting section 23 and a connecting combined section 24 in sequence along the direction far away from the end face of the cylinder 4. The cross-section of bearing installation section 23 is circular, and bearing installation section 23 overcoat is equipped with bearing 25 to be connected with the frame through bearing 25, set up the bearing frame in the frame, be used for installing bearing 25. The cross section of the connecting and combining section 24 is semicircular, and bolt holes 26 which are obliquely arranged are arranged on the connecting and combining section 24. The connecting and combining sections 24 on the connecting shafts of two adjacent cylinders 4 are mutually combined and locked through connecting shaft bolts, each connecting shaft bolt comprises a double-headed screw 27 and connecting shaft nuts 28 matched with two ends of the double-headed screw 27, and the double-headed screws 27 penetrate through bolt holes 26.

Since combing machines usually comprise a plurality of combing mechanisms, it is conventional practice in the prior art to connect the cylinders 4 directly in series via couplings and thus to drive them as a whole. However, the commercially available coupling has high cost and a complicated structure, or has poor stability and is easy to deform. Connecting shafts are arranged at two ends of the cylinder 4, and connecting combined sections 24 of the two connecting shafts are connected by inclined connecting shaft bolts. Because the connecting shaft bolt is arranged in an inclined mode, the connecting shaft bolt is more compliant with the rotation direction of the connecting shaft, more force applied to the connecting shaft bolt by the connecting shaft is pulling force along the length direction of the double-headed screw 27, and the transverse shearing force applied to the double-headed screw 27 is relatively weaker. By so doing, the risk of deformation of the double-threaded screw 27 can be greatly reduced, and the stability of the connection between the cylinders 4 is further ensured. Meanwhile, the mode has the advantages of extremely simple structure, convenient processing and extremely low manufacturing cost. In order to prevent the coupling nut 28 from protruding beyond the surface of the coupling shaft as a whole, the arc surface of the coupling segment 24 opposite to the bolt hole 26 is provided with a receiving groove 29 adapted to the coupling nut 28, and the coupling nut 28 is located in the receiving groove 29.

Further, on this basis, it may be better to further use a square groove is arranged in the middle of the plane on the connecting and combining section 24, a wedge 30 is clamped between the two connecting and combining sections 24 that are combined with each other, a groove cavity formed by the square grooves on the two connecting and combining sections 24 that are combined with each other is matched with the wedge 30, and a section of the bolt hole 26 is located on the wedge 30. The wedge block 30 not only can play a role in positioning the two connecting combined sections 24, improve the axial accuracy of the connecting shaft and reduce the installation difficulty, but also can play a role in key connection, further disperse the stress on the double-threaded screw 27 and further ensure that the connecting shaft has better stability. Further, it is also possible to connect the drive shafts of the various functional rollers by the same configuration.

The third great difference of the invention is that although the general principle is simpler, the improvement has excellent effect after long-term practice, the combing effect is greatly improved, and the invention is particularly suitable for producing high-grade yarns. As shown in fig. 9, the present invention further includes an atomizing and humidifying assembly 31 for humidifying the cotton layer 0 between the feeding mechanism and the carding mechanism, the atomizing and humidifying assembly 31 includes a water mist generator 32 and an axial flow fan 33, the axial flow fan 33 generally includes a cylindrical casing and a fan impeller arranged inside the casing, one end of the casing is an air inlet end, the other end is an air outlet end, the air outlet end of the axial flow fan 33 faces the cotton layer 0, and the inside of the casing, which is close to the air inlet end, of the axial flow fan 33 is communicated with an outlet of the water mist generator 32 through a conveying hose 34.

When the invention is used for humidification, firstly, the water mist generator 32 is started to generate water mist, the water mist is conveyed into the shell close to the air inlet end of the axial flow fan 33 along the conveying hose 34, then the water mist moves along the air flow direction, is mixed with air under the stirring and conveying action of the axial flow fan 33, and is blown to the cotton layer 0 to humidify the cotton layer 0. Then the cotton layer 0 enters the carding mechanism to be carded, the humidified cotton layer 0 can reduce the influence of static electricity, on one hand, fibers are easier to comb and straighten, on the other hand, impurities such as short fiber can be more thoroughly separated from cotton flocks, and the combing effect is further improved. The water mist generator 32 according to the present invention is preferably an ultrasonic type water mist generator 32, which has a better water mist generating effect. In addition, the phenomenon that the edge effect is poor due to the fact that air with water mist directly impacts the local cotton layer 0 to cause local over-wetting is avoided. A shell at the air outlet end of the axial flow fan 33 is provided with a trumpet-shaped diffusion opening 35, and the diffusion opening 35 can blow water mist to a cotton layer 0 in a dispersing manner.
