TECHNICAL FIELD
[0001] The present application belongs to the field of carbon fiber production equipment, and particularly relates to a carbon fiber warping equipment. BACKGROUND
[0002] Before carbonization of PAN-based carbon fibers, the precursor filaments need to be evenly spread into a certain width according to a certain arrangement. Since the width of the pre-oxidation furnace mouth is limited, in order to improve the production efficiency, increasing the number of filaments in the limited width of the furnace mouth becomes the most direct and effective method. However, the increase in the number of filaments leads to the decrease in the filament spacing, thereby causing the overlapping phenomenon between the adjacent tows to different degrees. During the process of passing through the pre-oxidation furnace, the precursor filaments with overlapping will cause defects such as doubling, broken filaments and split filaments in the resulting carbon fiber tows after the severe high-temperature oxidation and the stretching of the equipment, which greatly affects the production quality and production efficiency of the carbon fibers.
[0003] In order to reduce the generation of carbon fiber doubling defects, the operation of beating-up warping is generally increased during the production of carbon fibers nowadays, so that the precursor filaments are isolated by the weft threads to prevent doubling. In the prior art, the opening type cam beating-up method is adopted, that is, the front and rear beam frames with tows are controlled to move up and down relatively by a cam, so as to form an opening with a certain angle between the adjacent tows. The bobbin with weft threads is arranged in the opening as a weft thread carrier. When the equipment is running, the opening between the tows is too large, which greatly increases the tension of the tows and easily causes fiber breakage. Moreover, the mechanical structure of the warping equipment is complex. Some other methods use manual weft threading, which has low mechanization degree, cannot realize automation, wastes manpower and is prone to errors. In these methods, the bobbin with weft threads inevitably passes through the opening together, which causes the opening to be limited by the size of the bobbin.
[0004] The invention application with the application number CN200410077113.8 discloses a sampling warping machine with a straight-line yarn guide mechanism, which has a plurality of yarn guide units arranged in a straight line in front of the warping drum, and the yarn guide units are repeatedly rotated and stopped while the yarns drawn from the yarn supply bobbins arranged on the yarn guide units are wound on the conveying belt moving on the warping drum at a predetermined conveying amount according to a preset yarn arrangement sequence.
[0005] The application No. CN200610084501.8 discloses a sample warping method and a sample warping machine, in which during one rotation of the yarn guide, the multiple warps wound on the warping drum are arranged in the interval of the distance R with the warping density, the yarn guide ends are arranged in the interval of the distance R with the warping density, and the warps are wound on the warping drum from the warping direction to the reverse direction according to the winding sequence of the yarns wound on the warping drum.

[0071] Working process and principle
[0072] according to Figure 1 , Figure 2 The display shows a carbon fiber warping device comprising two symmetrically arranged fixed supports. A lifting device (i.e., a cylinder that drives the drive shaft to move up and down) is installed inside the support box. Two guide wires, a warping mechanism, and two upper and lower weft support rails (i.e., rails for the sliding of the active component) are arranged sequentially on the support. The warping mechanism consists of two parallel crossbeams installed on the support, a pair of magnetically coupled weft supports (i.e., a pair of moving pairs consisting of the active component and the driven component) symmetrically distributed along the upper and lower ends of the fastener, and a pair of weft feeding mechanisms installed on both sides of the support.
[0073] The modified snap-fit structure consists of several snaps with two grooves in the middle. The snaps are fixed to the upper and lower crossbeams at both ends. Under system control, the snaps can be pulled down or lifted by the guide wheel to create a certain gap (i.e., an open area) between adjacent wire bundles.
[0074] The buckles are spaced apart by two appropriately sized guide rollers, one above the other.
[0075] The opposing surfaces of the active and passive components are respectively provided with mutually attracting permanent magnets, which can stably suspend the passive component below the active component and allow it to move synchronously with the active component.
[0076] The driving member is installed on the slide rail, and the driving member can reciprocate on the slide rail under the system control through the motor driving.
[0077] The sliding block on the driven member is embedded in the track formed by the sliding groove of the buckle on the clasp, and the driven member has a shuttle hook of appropriate size on one side, which can hook the weft from the weft feeding mechanism and move with the driving member to the other side, and after the weft is taken into position, the driving member returns to the original position.
[0078] During operation, the warp yarns are separated into two groups of odd and even numbers by the drawing frame, and one group of yarns is periodically lifted and lowered to a fixed position by the driving of the guide rollers distributed between the clamps under the up-and-down periodic motion of the drawing frame, so as to form a certain opening between adjacent yarns, and then the weft is arranged in the middle of the warp yarns through the transverse motion of the magnetic coupling weft carrier, and since only the driven member of the magnetic coupling weft carrier needs to pass through the opening formed by the two groups of yarns during the weft carrying process, the opening angle is small, the filament tension is small, the risk of carbon fiber breakage is reduced, and the quality of finished carbon fiber is improved. The opening in the scheme can be controlled between 2-10 cm.
[0079] The technical features of the device are that: 1. Two smooth grooves are formed in the clamps in the warp drawing frame, and the clamps are arranged in parallel to form two groups of slide rails through which the driven parts of the weft carrier can pass;
[0080] 2. Two symmetrically arranged guide rollers are installed between the parallel arranged clamps, which lift (lower roller) and press (upper roller) the filaments to the specified position during the lifting and lowering of the drawing frame;
[0081] 3. The magnetic coupling weft carrier is divided into a driving part and a driven part, wherein the driving part is driven by a motor and can move on the guide rail of the drawing frame, and the sliding block of the driven part is embedded in the slide rail formed by the grooves of the clamps, and the driving part can drive the driven part to move synchronously through magnetic attraction.
[0082] Compared with the prior art, the carbon fiber warping device can lower or lift the filaments pressed on the guide rollers of the warp drawing frame under the system control, form a certain opening gap between adjacent filaments, and the magnetic coupling weft carrier and the weft processing device can complete the up-and-down interlacing weft action when the drawing frame lifts and lowers part of the filaments under the system control. The raw filaments reach an orderly distributed state before entering the pre-oxidation furnace, thereby preventing doubling, reducing hair and splitting, and improving the quality of finished carbon fiber in the carbon fiber production process.
[0083] The carbon fiber warping equipment of the present application, by establishing the improvement of the buckle piece, first of all, by setting two parallel beams on the upper and lower ends of the buckle piece, the buckle piece can be driven to move up and down, then the adjacent buckle pieces are set with godets at intervals, by the cooperation of the godets and the up and down movement of the buckle piece, the pulling of the yarn and the formation of the carding area are established; then by setting the slide rails along the direction of the warp distribution, the slide rail members that can be driven to slide are set in the slide rails, so that the weft insertion area becomes feasible, on this basis, on the one hand, by setting the slide rail area formed by the buckle on the buckle piece and setting the slide member in the slide rail area, the shuttle hook is set on the slide member, then the slide rail member is set as the driving member and the slide member is set as the driven member, by driving the driving member to move, the slide of the driven member along each slide rail area is established to complete the weft insertion; wherein the setting position of the slide rail area formed by the buckle on the buckle piece is set according to the buckle piece being pulled, and the slide rail area is just in the yarn opening area. And in order to cooperate with the precision control of the up and down weft insertion, a weft feeding mechanism is configured for each weft insertion. In summary, the carbon fiber warping equipment of the present application has a clever overall structure, can well control the tension of the yarn within a safe range, reduces the original opening of at least 20-30 cm to 2-10 cm, makes the original yarn bundle reach an orderly distribution state before entering the pre-oxidation furnace, thereby preventing the carbon fiber production process from plying, reducing the hair and splitting, and improving the quality of the finished carbon fiber.
