Description

Technical Field

[0001] The utility model relates to the technical field of fiber winding machines, in particular to a yarn spreading and arranging mechanism of a winding machine. Background Art

[0002] The winding machine is the main equipment for fiber winding. After the fiber tow is laid on the yarn rack, it goes through processes such as dipping and then is wound on the winding machine.

[0003] During the winding process, the tension of the fiber bundle plays a vital role in the molding effect. If the tension values ​​of multiple fiber bundles are not uniform, the winding on the mold will appear bulging or denting. Therefore, most winding machines are equipped with a tension adjustment mechanism. Figure 1 As shown, in the prior art, the tension adjustment of the yarn bundle is mainly regulated by the servo motor of the yarn release roller 11, and the control signal of the servo motor is issued by the tension sensor 13. The tension sensor is used to obtain the tension value of the yarn bundle 2 and transmit the tension value signal to the servo motor of the yarn release roller 11 to realize the tension control of the fiber yarn bundle.

[0004] In the prior art, after the fiber bundle 2 is drawn out by the yarn release roller 11, it first passes through a steering roller 12, and then the tension value is detected by the tension sensor 13. At least two sets of guide rollers in the horizontal direction and the vertical direction are set at the tension sensor 13. The guide roller group in the horizontal direction is composed of a first horizontal guide roller 14 and a second horizontal guide roller 15, and the guide roller group in the vertical direction is composed of a first vertical guide roller 16 and a second vertical guide roller 17. Under the action of the two sets of guide roller groups, the fiber bundle is guided in the X-axis and Y-axis directions, so that the fiber bundle can be located at a specific position on the tension sensor 13. After passing through the guide rollers, the fiber bundle will be subject to friction resistance from the guide roller group, especially the guide roller group in the vertical direction, which will cause the bundle tension value felt by the tension sensor to be distorted. The more guide roller groups the fiber bundle passes through, the more obvious its distortion is, which will eventually affect the winding molding effect.

[0005] In addition, the fiber bundle is prone to breakage after being rubbed by the guide roller group. Utility Model Content

[0006] The utility model aims to provide a yarn spreading and arranging mechanism for a winding machine, which can effectively control the tension value of a fiber bundle, thereby achieving a fiber winding and forming effect.

[0007] The technical solution of the utility model is:

[0008] A yarn spreading and arranging mechanism of a winding machine comprises a yarn putting roller, a tension sensor and a common roller, wherein the yarn putting roller is connected to the output end of a servo motor, the servo motor is connected to the tension sensor signal, guide wheels are respectively arranged on both sides of the tension sensor, and the circumference of the guide wheel is in the shape of a V-shaped groove.

[0009] The utility model replaces the arrangement of two groups of guide rollers in the horizontal direction and the vertical direction, which are four guide rollers in total, in the prior art by respectively arranging a guide wheel with a V-shaped groove on both sides of the tension sensor. Under the premise of ensuring the guiding function of the guide rollers on the fiber bundles, the friction resistance of the guide rollers on the fibers is effectively reduced by reducing the vertical guide roller group, thereby making the tension value obtained at the tension sensor more accurate, and then accurately controlling the servo motor at the yarn release roller, so that multiple groups of fiber bundles maintain a stable tension value, and improving the forming effect of the winding machine on the workpiece. Due to the reduction of the guide rollers, the overall structure of the yarn spreading structure of the winding machine is simpler.

[0010] The tension sensor and the guide wheels on both sides of the tension sensor are arranged on the same mounting seat.

[0011] In the utility model, the tension sensor and the guide wheel are arranged on the same mounting base. It is only necessary to ensure the horizontal state of the mounting base during installation to determine the relative position of the tension sensor and the guide wheel in the vertical direction, thereby ensuring the function of the tension sensor and reducing the difficulty of installation.

[0012] Specifically, the yarn spreading and arranging mechanism of the winding machine includes a mounting vertical plate, and the mounting seat is a C-shaped structure, including a front side plate parallel to the mounting vertical plate and an upper side plate and a lower side plate perpendicular to the front side plate, and the tension sensor and the guide wheel are vertically arranged on the front side plate.

[0013] Furthermore, a through hole is provided on the mounting plate corresponding to the mounting seat. The mounting plate is used to carry components such as the yarn release roller and the mounting seat, and the through hole is provided to facilitate wiring and to facilitate adjustment and maintenance of the tension sensor and the guide wheel.

[0014] The advantages and positive effects of the utility model are as follows: due to the adoption of the above technical scheme, under the premise of ensuring the function of the tension sensor, the friction resistance of the guide roller to the fiber bundle can be effectively reduced, so that the tension value of the fiber bundle felt by the tension sensor is more realistic, and the yarn unwinding and yarn arrangement mechanism of the winding machine is simplified.

[0022] like Figure 2 , 3 As shown, the utility model:

[0023] A yarn unwinding and arranging mechanism of a winding machine comprises a yarn unwinding roller 11, a tension sensor 13 and a common roller 3, wherein the yarn unwinding roller 11 is connected to the output end of a servo motor, the servo motor is connected to the signal of the tension sensor 13, guide wheels 4 are respectively arranged on both sides of the tension sensor 13, and the circumferential surface of the guide wheel 4 is in the shape of a V-shaped groove.

[0024] The utility model provides a V-shaped groove guide wheel 4 on both sides of the tension sensor, replacing the arrangement of two groups of guide rollers in the horizontal direction and the vertical direction, which are a total of four guide rollers in the prior art. Under the premise of ensuring the guiding function of the guide rollers to the fiber bundles, the vertical guide roller group is reduced, which effectively reduces the friction resistance of the guide rollers to the fibers, thereby making the tension value obtained at the tension sensor more accurate, and then accurately controlling the servo motor at the yarn release roller, so that multiple groups of fiber bundles maintain a stable tension value, and improving the forming effect of the winding machine on the workpiece. Due to the reduction of the guide rollers, the overall structure of the yarn spreading structure of the winding machine is simpler.

[0025] The tension sensor and the guide wheels on both sides of the tension sensor are arranged on the same mounting base 5.

[0026] In the utility model, the tension sensor and the guide wheel are arranged on the same mounting base. It is only necessary to ensure the horizontal state of the mounting base during installation to determine the relative position of the tension sensor and the guide wheel in the vertical direction, thereby ensuring the function of the tension sensor and reducing the difficulty of installation.

[0027] Specifically, the yarn spreading and arranging mechanism of the winding machine includes a mounting vertical plate 6, and the mounting seat is a C-shaped structure, including a front side plate parallel to the mounting vertical plate and an upper side plate and a lower side plate perpendicular to the front side plate, and the tension sensor and the guide wheel are vertically arranged on the front side plate.

[0028] Furthermore, a through hole 61 is provided on the mounting plate at a position corresponding to the mounting seat. The mounting plate is used to carry components such as the yarn release roller and the mounting seat. The through hole is provided to facilitate wiring and to facilitate adjustment and maintenance of the tension sensor and the guide wheel.

[0029] The working process of this example:

[0030] On the mounting vertical plate 6, multiple groups of yarn spreading components are arranged, each group of yarn spreading components includes a yarn release roller 11, a tension sensor 13 and guide wheels 4 arranged on both sides of the tension sensor 13, the tension sensor 13 and the guide wheels 4 on both sides of the tension sensor are arranged on the same mounting seat 5, the yarn release roller 11 and the common roller 3 are arranged above the mounting seat 5 in the vertical direction, and some mounting seats are arranged above the common roller, so it is necessary to arrange a guide wheel higher than the mounting seat between the mounting seat and the common roller 3 to ensure that the fiber bundle passes through the tension sensor 13 and the guide wheel 4 in a V-shaped path. The fiber bundle is drawn out from the yarn drum on the yarn release roller 11, first passes through the guide wheel on the left side of the tension sensor 13, then passes through the tension sensor and reaches the guide wheel on the right side of the tension sensor, and finally reaches the common roller 3.
