Description
Technical Field
The invention relates to a low-extension fiber stretch-breaking and stretch-making technology, in particular to a roller mechanism and a stretch-breaking machine for stretch-breaking and stretching low-extension fibers.
Background
The low-elongation fiber means that the extensibility of the fiber in the stretch breaking and drafting process is lower than that of common textile fibers, including but not limited to stainless steel metal fibers, glass fibers, carbon fibers and the like, in the processing industry of low-elongation fibers and derivative products, stretch breaking and drafting equipment is a conventional stretch breaking machine used in the textile field for stretch breaking, slivering and yarn making, and the stretch breaking machine is not produced according to the characteristics of the low-elongation fiber.
The rollers for the stretch-breaking and drafting of the textile fiber are standard S series synchronous belt tooth forms or tooth-form rollers for a spinning machine. The drawing and drafting equipment is provided with a plurality of pairs of drafting rollers, the fed fiber bundle is subjected to the continuous drafting action of the pairs of drafting rollers for a plurality of times, and when the degree of the drafting rollers for the fiber bundle exceeds the limit of the breaking elongation of the fiber, the fiber bundle is broken at any weak point of each monofilament. Since the tensile breaking points are randomly distributed, the breaking points are not located on a cross section of the drawn tow band, and the entire fiber band is not broken although the monofilaments in the fiber filament tow are already broken into a short fiber state. Therefore, the fiber bundles processed by the drawing and cutting direct slivering machine are directly processed into short fiber slivers, and the regular disc-shaped slivers with one circle and one circle can be conveniently formed by winding the coiler.
However, compared with organic/inorganic chemical fibers in the textile industry, low-elongation fibers such as metal fibers have the inherent characteristics of high elastic modulus, high bending resistance, tensile strength and the like of certain specific materials, and have the characteristics of higher low elasticity, high bending resistance, tensile strength and the like, and the problem caused by large static electricity of chemical fiber strips is not considered. However, other problems such as difficulty in fiber stretch-breaking are also increased, since the currently used rollers are standard synchronous belt tooth shapes or rollers suitable for spinning machines in the stretch-breaking and drafting processes, the conventional stretch-breaking machine needs more pressure and stronger holding force to stretch-break the fibers than the conventional fibers, and the stretch-breaking strip is easily bent excessively in the stretch-breaking and drafting processes under the action of huge pressure and holding force, has poor cohesion, and generates a large amount of broken fibers, thereby causing loss of raw materials and damage to the fiber strips.
Disclosure of Invention
The technical problem solved by the invention is as follows: aiming at the problem that the common spinning roller is used for low-extension fibers and has much broken fibers, a roller mechanism and a stretch breaker for stretch breaking and drafting of the low-extension fibers are provided.
The invention is realized by adopting the following technical scheme:
a roller mechanism for low extension fibre is drawn and is cut and draft, smooth roller and profile of tooth roller including the pair roller setting, smooth roller has elastic surface, evenly be equipped with a plurality of skewed teeth along the circumferencial direction on the profile of tooth roller, all skewed teeth on the profile of tooth roller are compared in the setting of slope of the same side of the radial direction orientation of place separately, and the variation of the closed interval distance that skewed tooth on the profile of tooth roller formed at the pair roller in-process reduces the disconnected fibre that the centre gripping fibre caused simultaneously between two adjacent teeth.
One kind is used for low roller mechanism who extends fibre stretch-breaking and draft in the above-mentioned scheme, and is further, the skewed tooth includes one side inclined plane and the tooth top with the direct butt joint of inclined plane of adjacent skewed tooth, the tooth top is the evagination circular arc tooth top tangent with the inclined plane of affiliated skewed tooth, tooth top one end is tangent in the inclined plane of affiliated skewed tooth, and the other end extends to the tooth root of adjacent skewed tooth.
In the roller mechanism for stretch-breaking and drafting of the low-elongation fiber, further, the inclination angle of the inclined plane and the radial direction of the inclined teeth is 50-70 degrees.
In the roller mechanism for stretch-breaking and drafting of the low-elongation fiber, further, the arc radius of the tooth top is R1.2-R2.2.
In the roller mechanism for the drafting and drafting of the low-elongation fiber in the scheme, furthermore, the number of the teeth on the toothed roller is 1/2 of the circumferential diameter of the roller.
In the roller mechanism for the traction cutting and drafting of the low-extension fibers, the inclined direction of the helical teeth faces the direction of the roller pair of the tooth-shaped roller, so that the traction cutting effect on the fibers required by the change of the distance between closed areas formed by the adjacent helical teeth in the roller pair process can be ensured.
In the roller mechanism for the stretch breaking and drafting of the low-elongation fiber, further, the inclined angles of all the inclined teeth on the toothed roller are the same.
The invention also discloses a stretch breaking machine which comprises a stretch breaking system formed by a plurality of groups of roller mechanisms, wherein a pre-stretching area, a main stretching area and a leakage-proof stretching area are sequentially formed between two adjacent groups of roller mechanisms, and a first relaxing area and a second relaxing area are respectively arranged between the pre-stretching area and the main stretching area and between the main stretching area and the leakage-proof stretching area through the two adjacent groups of roller mechanisms.
In the stretch breaker in the above scheme, the stretch breaker further comprises a coiler butted with the stretch breaker system, and coiling are performed on the stretch breaker fiber.
When low-elongation fibers such as stainless steel metal fibers are subjected to stretch cutting, the roller pressure is required to be increased to ensure the holding force in the stretch cutting process, when the holding force is too large, the fiber strips are excessively bent and have more broken fibers due to the tooth shape of the roller, and when the pressure is not increased and the holding force is not enough, the phenomenon that the fiber strips are uneven due to the fact that excessive overlong fibers exist in the fiber strips, hard ends and broken ends occur in the spinning process is caused. The invention aims at the prior traction cutting processing of low-extension fiber, which generally adopts a standard S series roller and a roller for a spinning machine, ensures the evenness and the low fiber amount of the traction cutting strip by designing and adopting a helical tooth roller and selecting a tooth form of the traction cutting roller special for the low-extension fiber, ensures that the traction cutting strip has enough holding force aiming at the fiber in the traction cutting process by selecting the tooth number of the helical tooth, changes the tooth form shape of the tooth form roller, the holding force of a smooth roller and the roller to the traction cutting strip can be increased under the same pressure, can increase the pressure adjusting range under different pressures without generating excessive bending of a large amount of broken fibers and fiber strips caused by the traction cutting of a common roller, ensures the full breaking of the fiber and the quality of the evenness after the traction cutting strip, and solves the traction loss caused by the low-extension fiber in the traction cutting process, and influence on subsequent processes caused by uneven stretch-breaking strips.
The invention is further described with reference to the following figures and detailed description.

Detailed Description
Referring first to fig. 1-3, the analysis was performed for the state of the stainless steel fiber bundle in the low elongation fibers as it passed through the nip of the roller rollers. The illustration is for a standard conventional S5M tooth form: when the leather roller and the roller are contacted, the contact area is only converted into an integer of n & gt 0 from n teeth to n +1 teeth (namely, the leather roller and the roller are only converted between odd teeth and even teeth).
Take the example of the diameter of the roller of the leather roller being 100mm, the tooth shape being standard S5M, and the pressure of the leather roller being 60 KG. The contact between the leather roller and the roller is shot by a camera to be 2-3 teeth, and the running process is divided into two states: as shown in FIG. 1, the crest of the tooth form of the spur teeth 21 of the toothed roller 2 is aligned with the center of the smoothing roller 1, and as shown in FIG. 2, the center of the tooth groove of the spur teeth 21 of the toothed roller 2 is aligned with the center of the belt roller.
In the analysis of fig. 1, in a semi-closed area 301 formed by two adjacent straight teeth 21 and the smooth roller 1, the fiber gripping point of the tooth-shaped roller 2 and the smooth roller 1 only has one straight tooth 21 which is firstly pressed against the smooth roller 1, the center distance between the smooth roller 1 and the tooth-shaped roller 2 is the farthest, and in the area, a single gripping point cannot damage the stainless steel fibers, and only the fibers are normally broken. When the toothed roller 2 rotates to make the smooth roller 1 tangent to the next adjacent straight tooth 21, a first closed area 302 is formed, the tooth of which is contacted with the smooth roller 1 in the rotating direction, the length of the stainless steel fiber in the first closed area 302 is limited to a fixed value L1, when two straight teeth are measured, L1 is 2.523mm, when the smooth roller 1 is switched to be uniformly pressed on a tooth space between the adjacent straight teeth 21, the fiber in the closed area has two holding points, when two closed areas 303 are formed, the straight teeth 21 are symmetrically contacted with the smooth roller 1, when the smooth roller deforms and expands in the closed area due to pressure and the distance between the center of the smooth roller and the center of the roller is reduced, when the fiber length L2 in the closed area is measured as L2 is 2.936mm, and L2 is greater than L1, the process causes the two adjacent straight teeth and smooth roller to press the fiber to change the length, when the elastic deformation amount of the stainless steel metal fiber is exceeded, the fibers are crushed. In this process, every time the stainless steel metal fiber passes through a closed space between adjacent spurs 21, a portion of the stainless steel metal fiber is crushed, resulting in a large amount of broken fibers and a damaged evenness.
Example one
Referring to fig. 4 and 5, the roller mechanism shown in this embodiment is a specific embodiment of the present invention, and is used for stretch-breaking and drafting of stainless steel metal fibers, and includes a smooth roller 1 and a tooth-shaped roller 2, which are arranged in a pair-roller manner, the smooth roller 1 is a leather roller, and has an elastic circumferential surface, so as to avoid directly pinching off the metal fibers with the tooth-shaped roller 2 in the pair-roller process, the tooth-shaped roller 2 is uniformly provided with a plurality of helical teeth 22 along the circumferential direction, a single helical tooth 22 extends along the axial direction of the tooth-shaped roller, and on the cross section of the tooth-shaped roller 2, all the helical teeth 22 on the tooth-shaped roller 2 are inclined toward the same side in the radial direction as the respective.
As shown in fig. 5, the helical tooth 22 includes a side inclined surface 221 and a tooth top 222 directly abutting against the inclined surface 221 of the adjacent helical tooth, the helical tooth 22 in this embodiment has only one side inclined surface 221, the tooth top 222 is a convex arc tooth top tangent to the inclined surface 221 of the associated helical tooth, such that one end of the tooth top 222 is tangent to the inclined surface of the associated helical tooth, the other end extends to the tooth root of the inclined surface 221 of the adjacent helical tooth, and the arc-shaped structure of the tooth top 222 extends to form the other side edge of the helical tooth. The toothed roller 2 is of a rigid structure, and the tooth tops 222 of the helical teeth can be partially pressed into the elastic surface of the smooth roller 1 in the process of being paired with the smooth roller 1.
Experiments prove that the inclined direction of the inclined teeth 22 of the toothed roller 2 is to face the direction of the roller pair of the toothed roller 2, the inclination angle of the inclined surface 221 of the inclined teeth 22 and the radial direction of the inclined teeth is 50-70 degrees, so that the change of the distance between the closed areas formed by the inclined teeth 22 on the toothed roller 2 in the roller pair process can reduce the broken fiber caused by simultaneously clamping the metal fiber between two adjacent teeth, and the inclination angles of all the inclined teeth 22 on the toothed roller 2 are the same.
Hereinafter, a process of stretch-breaking the stainless steel metal fibers 5 by the roller structure of the present embodiment will be described as an example, and a principle of the toothed roller 2 of the present embodiment that the stainless steel metal fibers are less pinched and broken when passing through the nip point of the roller will be described in detail with reference to fig. 6 and 7.
In the roller structure in fig. 6 and 7, in the helical teeth 22 of the toothed roller 2, the inclination angle of the inclined surface 221 is 65 °, and the circular arc radius of the tooth crest 222 is R1.6, in fig. 6, when the smooth roller 1 newly contacts the next helical tooth 22 in the stretch-breaking process, that is, when the first closed area 302 is to be formed, the length L1 of the stainless steel metal fiber in the first closed area 302 in the present embodiment is 2.736mm due to the inclined surface 221 of the helical tooth 22, which is longer than the length L1 of the straight-tooth roller in fig. 2. In fig. 7, when the center of the first closed area 302 turns to the center line of the smooth roll 1 and the toothed roller 2, the leather roll on the left side of the stainless steel metal fiber is continuously pressed downwards by the tooth top of the oblique tooth contacted with the leather roll, but the contact area of the oblique tooth and the surface of the smooth roll 1 is increased due to the inclined surface of the tooth form 22, the tooth top 222 is pressed into the surface of the smooth roll 1 by a smaller amount than the straight tooth form in fig. 2, meanwhile, the tooth top 222 of the oblique tooth 22 of the leather roll pressed into the right side of the stainless steel metal fiber is gradually lifted from the deepest position pressed into the surface of the smooth roll 1, the stainless steel metal fiber held by the oblique tooth is released, in the second closed area 303 where two oblique teeth 22 are simultaneously pressed into contact with the smooth roll 1, the length L2 of the stainless steel metal fiber is 2.668mm, and is reduced compared with the straight tooth roller in fig. 3, and the closed area 2 rotates back and forth, l1 is more than L2, the stainless steel metal fiber can not be broken, and the broken fiber can not be generated, so that the evenness of the yarn can not be damaged.
The inclination angle of the helical teeth 22 of the toothed roller 2 is selected according to the pressing depth of the toothed roller to the smooth roller, when the inclination angle of the inclined surface of the helical teeth 22 is higher than 70 degrees, the helical teeth 22 are basically and completely pressed into the surface of the smooth roller 1, ninety percent of two adjacent helical teeth are in contact with the smooth roller 1, so that L1 is larger than L2, the contact surface between the two is large, the fiber strips are free of cohesive force, and when the inclination angle of the inclined surface of the helical teeth 22 is lower than 50 degrees, the tooth tops of the helical teeth 22 are far lower than the pressing depth, and the effect of stretch-breaking on the stainless steel metal fibers is completely avoided.
When the diameters of the toothed rollers 2 are the same, the more the number of the helical teeth 22 is, the more the closed area on the holding point of each smooth roller and roller is increased, the increased contact area can cause the cohesive force of the fiber strips after coiling to be poor, and multiple experimental researches find that the number of the helical teeth 22 on the toothed rollers 2 is selected to be the most appropriate half of the diameter of the rollers, so that the strips are ensured to keep a certain cohesive force after the whole stretch-breaking process of the stainless steel metal fibers.
Example two
Referring to fig. 8, the stretch breaker for stainless steel metal fiber disclosed in this embodiment is a specific embodiment of the stretch breaker of the present invention, which includes several groups of stretch breaker systems formed by roller mechanisms in the first embodiment and a coiler 42. The stretch-breaking system comprises six groups of roller mechanisms which are arranged along the horizontal direction, a pre-stretching area 401, a first loosening area 402, a main stretching area 403, a second loosening area 404 and a leakage-proof stretching area 405 are sequentially formed between two adjacent groups of roller mechanisms, the structural parameters of each roller mechanism are the same, the draft ratio between the front roller mechanism and the rear roller mechanism in different areas is determined according to process requirements, the rotating speed of the roller pairs of the roller mechanisms in the outlet direction of the pre-stretching area 401, the main stretching area 403 and the leakage-proof stretching area 405 is higher than that of the roller mechanisms in the inlet direction, and the rotating speed of the roller pairs of the roller mechanisms in the outlet direction and the inlet direction of the first loosening area 402 and the second loosening area 404 are the same. After being led out from the raw material frame 41, the stainless steel fibers 5 sequentially pass through the space between smooth rollers and toothed rollers of a six-roller mechanism, are pulled to sequentially pass through a pre-pulling area 401, a first loosening area 402, a main pulling area 403, a second loosening area 404 and an anti-leakage pulling area 405, and are then pulled to a coiler 42 to coil.
