Description

Technical Field

[0001] This utility model relates to the field of circular loom supporting facilities, specifically to a CNC take-up machine. Background Technology

[0002] A circular loom is an industrial device used to process woven tube fabric. The warp frame of a circular loom has many spindles. The number of warp yarns used is within a specified range according to the width of the woven fabric and the width of the flat yarn. Before the warp yarns enter the circular loom, the warp yarn frame makes a cross opening between the warp yarns. The weft shuttle moves in a circular motion through the warp yarns in the cross opening to weave the tube fabric.

[0003] Therefore, a weft bobbin needs to be installed on the weft shuttle, and the weft yarn on the weft bobbin needs to be wound by a take-up machine. A traditional take-up machine includes a frame and a swing frame. The swing frame is equipped with a twisting shaft, a guide rail, and a guide roller. The guide rail is equipped with a guide gauge that is adapted to the twisting shaft to move back and forth on the guide rail. The front of the frame is also equipped with a take-up shaft that is parallel to the axis of the twisting shaft. The take-up shaft is equipped with a take-up clamp for fixing the weft bobbin.

[0004] When the take-up shaft rotates, the twisted shaft drives the guide gauge to move back and forth to arrange the weft yarn and wind it onto the weft bobbin. Therefore, existing take-up machines have a high-power motor at the rear of their frame, which distributes power to the take-up shaft through synchronous pulleys, synchronous belts, and tension pulleys. At the same time, a drive shaft coaxial with the hinge axis is installed at the hinge joint between the swing frame and the frame, transmitting the power located at the rear of the frame to the end of the swing frame away from the frame, and then transmitting the power to the twisted shaft through synchronous pulleys, synchronous belts, and tension pulleys. This process consumes a lot of motor power. At the same time, since the whole machine is synchronously driven, as the diameter of the weft bobbin gradually increases with the take-up (with the rotation speed remaining constant), the take-up linear speed increases (which is a variable), while the reciprocating speed of the guide gauge in synchronous drive does not change, resulting in a speed difference between take-up and take-up, which affects the take-up effect. Utility Model Content

[0005] Based on the above problems, the purpose of this utility model is to provide a CNC winding machine that can control the winding speed and the winding speed according to the winding state.

[0006] To address the above problems, the following technical solution is provided: A CNC take-up machine includes a frame, with a swing frame hinged to one side of the frame's front side, the hinge axis of the swing frame being perpendicular to the front side of the frame; the swing side of the swing frame is provided with a twisting shaft, a wire guide rail, and a wire roller parallel to the swing axis, the wire guide rail being provided with a wire gauge adapted to the twisting shaft to reciprocate on the wire guide rail; the front side of the frame also has a take-up shaft parallel to the axis of the twisting shaft, the take-up shaft being provided with a take-up clamp; the swing frame swings to move the wire roller closer to or away from the take-up shaft, the back side of the frame is provided with a take-up servo / stepper motor for driving the take-up shaft to rotate; the swing frame is provided with a wire guide servo / stepper motor for driving the twisting shaft to rotate; and a controller is also included for controlling the speed of the take-up servo / stepper motor and the wire guide servo / stepper motor.

[0008] The present invention is further configured such that the cable servo / stepper motor is an external rotor motor or an internal rotor motor.

[0010] The present invention is further configured such that the swing side of the swing frame is provided with a concave shaft cavity, and the twisted shaft is located inside the shaft cavity; the cable guide rail and the wire gauge are located at the cavity opening of the shaft cavity.

[0011] The present invention is further configured such that the guide rod is arc-shaped, and the distance from its middle section to the guide roller is greater than the distance from its two ends to the guide roller.

[0012] The present invention is further configured such that the frame is also provided with a tension switch, the tension switch is provided with a tension arm extending outward from the front of the frame, the end of the tension arm is provided with a tension wheel, and the axis of the tension wheel and the swing axis of the tension arm are parallel to each other while being offset from each other.

[0013] The present invention is further configured such that a groove is provided at the middle section of the outer wall of the tension wheel in the axial direction, and the groove corresponds to the middle section of the reciprocating stroke of the guide gauge.

[0014] The present invention is further configured such that the power output end of the take-up servo / stepper motor is directly coaxially connected to the take-up shaft; and the power output end of the cable laying servo / stepper motor is directly coaxially connected to the twist shaft.

The speed is adjusted according to the change of weft yarn bobbin diameter after take-up to ensure the stability of take-up.

[0019] 2. At the same time, since the take-up servo / stepper motor and the cable servo / stepper motor are direct drives without intermediate power transmission components, they can effectively ensure sufficient power, reduce energy loss, and are suitable for adapting to low-power motors.

[0020] 3. For the take-up servo / stepper motor and the cable laying servo / stepper motor, servo motors are preferred for driving, which avoids step loss while ensuring torque at high speeds;

[0021] 4. By reducing the intermediate transmission mechanism and replacing it with a smaller motor, the weight can be effectively reduced, thus enabling weight reduction of the frame;

[0022] 5. Since the high-power motor and complex transmission structure have been eliminated, the weight has been effectively reduced. Therefore, the frame is made of metal material and directly molded by injection molding, avoiding subsequent drilling and other processing. Attached Figure Description
