Description
Technical Field
The invention relates to the technical field of yarn bundle unreeling creels, in particular to a multi-yarn bundle unreeling creel for forming two-dimensional yarn faces and three-dimensional preformed bodies.
Background
High performance fibers, such as carbon fibers, aramid, ultra high molecular weight polyethylene, and the like, are increasingly being used. All high performance fibers are presented in the form of a spindle and then the application of these fibers to make an intermediate material requires an unreeling process. This is the first process step downstream of the high performance fiber, and the result output from the unreeling process directly affects the quality and manufacturing efficiency of the downstream product. With the deep understanding of the downstream process, the workers of each process gradually find that the existing unreeling creel design can not meet the requirement of high-performance fiber post-treatment, the expensive fiber treatment is rough, the quality refinement requirement is continuously improved, and the discovery that the spindle unreeling process comprises a plurality of technical and innovative spaces is carried out.
The existing unreeling creel seriously ignores the self characteristics of high-performance fibers, and only serves the high-performance fibers by means of the unreeling creel (or creel) of the traditional textile industry. Compared with common chemical fibers, the high-performance fibers are more sensitive to the outside, such as carbon fibers, have very strong toughness in the axial direction, but have very weak mechanical properties in the radial direction, and the higher the modulus is, the more easily the radial direction is damaged. We use high performance fibres in order to develop their excellent mechanical properties, but if they are damaged in the first (unreeling) step, they will destroy their properties and cause problems for downstream process manufacture. On the other hand, all of our conventional unwind reels, more than one tow face (plane) is formed downstream, one tow face is formed, i.e. all tows are in the same plane, without forming a three-dimensional unidirectional multi-tow preform. Traditionally, this preform is done in a downstream process, which can multi-tamper the tow, resulting in more serious damage to the tow and affecting the quality of the downstream product.

Detailed Description
The invention will be described in further detail with reference to the drawings and the detailed description.
In order to facilitate the unified viewing of the various reference numerals within the drawings of the specification, the reference numerals appearing in the drawings of the specification are now collectively described as follows:
1 is a bracket, 2 is a lifting mechanism, 3 is a first limiting wheel, 4 is a second limiting wheel, 5 is a spindle, 6 is a silk bundle, and 7 is an oblique beam.
For convenience of description, the following orientations will be described below: the direction of the axis of the spindle is the longitudinal direction, the direction of the axis of the first limiting wheel is the transverse direction, and the direction of the axis of the second limiting wheel is the vertical direction.
Referring to fig. 1,2,3 and 4, a multi-tow unreeling creel for forming a two-dimensional wire surface and a three-dimensional preform comprises a bracket and a plurality of unreeling mechanisms arranged on the bracket. Regarding the unreeling mechanism as a whole, a plurality of unreeling mechanisms are arranged in sequence along the transverse direction. Each unreeling mechanism comprises a plurality of unreeling units. Each unreeling unit comprises a spindle rotatably mounted on the support, and a first limiting wheel and a second limiting wheel rotatably mounted. The spindle, the first limiting wheel and the second limiting wheel can rotate, and the first limiting wheel and the second limiting wheel can be fixed on the support or other places. The spindle axis is along the longitudinal direction, the axis of the first spacing wheel with adjustable height position and longitudinal position is along the transverse direction, the axis of the second spacing wheel with adjustable height position and longitudinal position is along the vertical direction, and the height position and longitudinal position of the first spacing wheel and the second spacing wheel are adjustable. The yarn bundles are precisely staggered and wound into yarn ingots, namely the yarn bundles are spirally wound on the yarn ingots, and after the yarn bundles are wound, the whole yarn ingots are cylindrical. The yarn bundles coming out from the tangential direction of the spindle sequentially tangentially wind into the first limiting wheel, tangentially wind out of the first limiting wheel, tangentially wind into the second limiting wheel and tangentially wind out of the second limiting wheel; the yarn bundle is fed out from the tangential direction of the spindle, then enters the first limiting wheel from the tangential direction of the first limiting wheel, then is fed out from the tangential direction of the first limiting wheel, then enters the second limiting wheel from the tangential direction of the second limiting wheel, and then is fed out from the tangential direction of the second limiting wheel.
As shown in fig. 1,3 and 4, the support is provided with a plurality of inclined beams, and all the spindles in each unreeling mechanism are arranged along the inclined direction and are rotationally arranged on the same inclined beam, namely, all the spindles are arranged upwards along the inclined direction and are fixedly arranged on the same inclined beam in the same unreeling mechanism. The axes of all the spindles in each unreeling mechanism are in the same inclined plane, and the included angle between the inclined plane and the horizontal plane is an acute angle. All the first limiting wheels of each unreeling mechanism are sequentially arranged along the transverse direction, namely in the same unreeling mechanism, all the first limiting wheels are arranged and fixed along the transverse direction, and the heights of the first limiting wheels can be consistent or inconsistent. All the second limiting wheels of each unreeling mechanism are sequentially arranged along the oblique direction, namely, all the second limiting wheels are arranged and fixed along the oblique direction in the horizontal plane in the same unreeling mechanism, and the heights of the second limiting wheels can be consistent or inconsistent. The first limiting wheels in different unreeling mechanisms are not positioned at the same height position, and the second limiting wheels in different unreeling mechanisms are not positioned at the same height position; i.e. different unreeling mechanisms, the heights of the first limit wheel and the second limit wheel are not uniform. Since the height positions of all the first limiting wheels and the second limiting wheels are adjustable, the positions in the longitudinal direction are also adjustable, and after all the tows come out of the second limiting wheels, the gaps among the tows in the height direction can be controlled and adjusted, so that a two-dimensional silk surface and various types of three-dimensional preformed bodies can be formed, wherein the two-dimensional silk surface is the same height as all the tows, the three-dimensional preformed bodies are the same height as some tows, and some tows are not the same height as the three-dimensional preformed bodies, for example, the two-dimensional silk surface is the strip-shaped preformed bodies; FIG. 6 is a cylindrical preform; FIG. 7 is a tube preform; fig. 8 is an i-shaped type preform.
All first limiting wheels of each unreeling mechanism are located at the same height, and all second limiting wheels of each unreeling mechanism are located at the same height. Thus, after all tows exit the second limiting wheel, all tows in the same unreeling mechanism are positioned at the same position, and a strip-shaped preformed body is formed as shown in fig. 5.
The mounting modes of the first limiting wheel and the second limiting wheel are two, and the first is: in order to adjust the heights of the first limit wheel and the second limit wheel, a lifting mechanism can be arranged on the bracket; the first limiting wheel and the second limiting wheel are fixed on the lifting mechanism. In order to adjust the positions of the first and second spacing wheels in the longitudinal direction, the lifting mechanism is provided with a plurality of mounting positions (mounting areas) which are arranged along the longitudinal direction and used for fixing the first and second spacing wheels, i.e., the lifting mechanism is provided with a plurality of mounting positions (mounting areas), and then the first and second spacing wheels are fixed at the positions. The lifting mechanisms are multiple, and all the first limiting wheels and the second limiting wheels in the same unreeling mechanism are fixed on the same lifting mechanism.
The second is: the support is provided with a plurality of lifting mechanisms, at least one longitudinal translation mechanism is arranged on each lifting mechanism, and all the first limiting wheels and the second limiting wheels in the same unreeling mechanism are arranged on the longitudinal translation mechanism of the same lifting mechanism, so that the first limiting wheels and the second limiting wheels can be controlled by one longitudinal translation mechanism. Of course, two longitudinal translation mechanisms may be used to control the first and second spacing wheels, respectively. Lifting mechanism and vertical translation mechanism belong to prior art.
The tow forms a wrap angle of 90 degrees after winding into the first limiting wheel, and forms a wrap angle of 90 degrees after winding into the second limiting wheel. The wrap angle of 90 degrees can ensure that all tows are in parallel relation.
The tows are chemical fibers in multifilament form or prepreg tapes pre-soaked by resin, and the cross section of the tows is rectangular.
The first limiting wheel and the second limiting wheel are both positioned above the spindle, and the rollers of the first limiting wheel and the second limiting wheel are V-shaped rollers, arc-shaped rollers or flat-bottom rollers.
The unreeling creel disclosed by the invention also relates to other electrical equipment, and the like, and the tension control of the spindle is ensured under the factors of machinery, electricity or magnetic field, namely the constant Zhang Liqie of the filament bundles under various conditions is ensured to unreel. The yarn bundle usually adopts a precise staggered winding (spiral winding) mode to become a yarn spindle, when the yarn bundle is unreeled, the yarn bundle comes out from the tangential direction of the yarn spindle and moves back and forth in the axial direction (longitudinal direction) of the yarn spindle, but the yarn bundle enters the first limiting wheel from the middle position of the first limiting wheel and from the tangential direction, so that the yarn bundle is prevented from moving back and forth in the axial direction (transverse direction) of the first limiting wheel, if the axial direction of the yarn spindle is parallel to the axial direction of the first limiting wheel, the yarn bundle moves back and forth in the axial direction (transverse direction) of the first limiting wheel, the friction between the yarn bundle and the first limiting wheel is increased, the performance of the yarn bundle is damaged, the yarn bundle can collide with a baffle plate at the edge of the first limiting wheel, and the yarn bundle width of the first limiting wheel is narrowed passively. The first limiting wheel and the second limiting wheel are used for guiding and conveying the tows, and damage to the tows is minimized. The unreeling creel eliminates friction generated by the reciprocating motion of the yarn bundle in the axial direction of the roller (namely, the reciprocating motion in the axial direction of the roller) by changing the relative motion of the working surface of the roller (namely, the roller of the spindle, the first limiting wheel or the second limiting wheel) and the yarn bundle surface, thereby further causing damage to the yarn bundle. The guiding of the yarn bundles of the unreeling creel is completed by a roller, each yarn bundle has a respective yarn path, the yarn paths are not shared with other yarn bundles, sliding friction with mechanical parts is avoided, if the moving direction of the yarn bundles is changed, the yarn bundles need to be completed in one plane (for example, the yarn bundles are wound in and wound out of a first limiting wheel from the tangential direction, and the yarn bundles are wound in and wound out of the tangential direction, so that the yarn bundles are in one plane), the angle of each direction change is 90 degrees, and the yarn bundles are kept straight in the plane. The concentration and preforming of the multiple tows are realized by rolling friction rollers, the three-dimensional space positions of all the rollers are adjustable, and the position relation among the tows is adjustable. By guiding and collecting the tows, a two-dimensional tow surface with controllable and adjustable tow width and adjustable tow gap can be formed, and a three-dimensional unidirectional multi-tow preformed body can be formed, wherein the preformed body comprises the shape of all industrial sectional materials such as a cylinder, a ring, an I-beam and the like; two-dimensional tow facets and three-dimensional unidirectional tow preforms. After the unreeling process, prepreg tows can be adopted, and the tows are heated by a die to realize adhesion and solidification, so that a two-dimensional tow surface and a three-dimensional unidirectional tow preform with stable structures can be formed.
Conventionally, after unreeling, a three-dimensional unidirectional multi-tow preform is not formed, and then a plurality of tows are separated by axial friction of a downstream process, such as porcelain eye (a ceramic with a plurality of holes), a yarn dividing comb (similar to a comb) and a roller, so that the tows can touch the porcelain eye and the yarn dividing comb in the radial direction, and mechanical damage is caused to the tows. The unreeling creel has the beneficial effects that as the whole system does not have porcelain eyes, yarn splitting combs and axial friction of rollers, the mechanical damage to the yarn bundles is minimized; the yarn spindle unreeling tension is constant, rolling friction is adopted, so that the original width of the yarn bundles can be kept, and the yarn bundle width is well controlled; the porcelain eyes and the yarn splitting combs are not needed to guide and concentrate the yarn bundles, the yarn channel of each yarn bundle does not forcefully change the direction, and all the direction changes softly and smoothly; and forming the two-dimensional tow surfaces and the three-dimensional unidirectional multi-tow preformed body with controllable and adjustable filament widths and adjustable gaps required by downstream processes by utilizing a roller system in a three-dimensional space. And various mechanical devices are not needed to be used downstream for secondary damage to the filament bundles. Therefore, the product quality of the downstream process can be greatly improved, and meanwhile, as the number of broken filaments is small, the cleaning work is small, a large amount of manpower can be saved, and the production efficiency is improved.
The invention also relates to an unreeling creel of the silk bundle, which comprises a spindle, a first limiting wheel and a second limiting wheel which are rotatably arranged; the axis of spindle is along longitudinal direction, and the axis of first spacing wheel is along horizontal direction, and the axis of second spacing wheel is along vertical direction, and the silk bundle that comes out from spindle tangential direction is tangential to wind into first spacing wheel, tangential to wind out first spacing wheel, tangential to wind into second spacing wheel, tangential to wind out second spacing wheel in proper order.
