Description
Technical Field
[0001] The utility model relates to the technical field of wire pay-off machines, in particular to an active wire pay-off unit and an active wire pay-off machine. Background Art
[0002] When the wire is being paid off, active pay-off is usually adopted. In order to ensure the stability of the wire tension during the pay-off process, the tension is generally detected by the rotation angle of the tension swing rod, and the rotation speed of the wire drum is adjusted according to the detection data to keep the tension stable.
[0003] At present, the existing pay-off machine does not have a break protection mechanism. When the wire breaks accidentally, the tension swing arm will rotate counterclockwise quickly, causing it to collide and rub with the rotating wire drum shaft below, thereby causing wear and tear on the tension swing arm and the wire drum shaft, affecting the service life. In addition, the existing pay-off machine mainly guides the wire outlet direction through the guide wheel. Since the wire may deviate in the wheel groove of the guide wheel, the guiding effect is poor, which does not meet the process requirements of accurate wire outlet. Utility Model Content

[0008] Furthermore, the guide assembly includes a guide shaft, a guide wheel and a guide block. There are two guide shafts, which are installed in parallel and at intervals on the front side of the frame. The guide wheel is installed at the front end of the guide shaft, and the guide block is installed at the front end of the leftmost guide shaft. A guide hole is opened on the guide block.
[0009] Furthermore, the tension detection assembly also includes a rotating shaft, a tension wheel, a counterweight and a detector.

DETAILED DESCRIPTION
[0025] The present invention is now further described in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0026] Example 1
[0027] like Figure 1As shown, an active pay-off unit includes a frame 100, an active pay-off assembly 200 installed in the middle of the frame 100, a guide assembly 300 installed in the upper left corner of the frame 100, a controller 400 installed in the upper right corner of the frame 100, and a tension detection assembly 500 arranged between the active pay-off assembly 200 and the guide assembly 300, the controller 400 controls the active pay-off assembly 200 and the tension detection assembly 500, the tension detection assembly 500 includes a tension swing rod 510 rotatably installed on the front side of the frame 100, and a limit column 600 is installed on the front side of the frame 100, and the limit column 600 is located between the active pay-off assembly 200 and the tension swing rod 510. By setting the limit column 600 between the active pay-off assembly 200 and the tension swing rod 510, when the silk thread is accidentally disconnected, the limit column 600 will limit the rotation angle of the tension swing rod 510 to prevent it from colliding and rubbing with the rotating wire drum shaft 210 below, thereby ensuring the service life of the tension swing rod 510 and the wire drum shaft 210. Specifically, the tension swing rod 510 is L-shaped. It should be noted that during the normal tension adjustment process of the output line, the tension swing rod 510 and the limit column 600 will not come into contact, and will only come into contact when the silk thread is accidentally disconnected or the silk thread is used up.
[0028] like Figure 1 and Figure 2 As shown, the active pay-off assembly 200 includes a wire drum shaft 210, a motor 220 and a transmission assembly 230. The wire drum shaft 210 is inserted into the frame 100 and rotates with the frame 100. The motor 220 is installed at the rear side of the frame 100, and its output end is connected to the rear end of the wire drum shaft 210 through the transmission assembly 230. The motor 220 is connected to the controller 400, and the limit column 600 is arranged between the wire drum shaft 210 and the tension swing rod 510. Specifically, the motor 220 is a brushless motor; the transmission assembly 230 includes a main pulley 231, a slave pulley 232 and a belt 233. The main pulley 231 is installed at the output end of the motor 220, the slave pulley 232 is installed at the rear end of the wire drum shaft 210, and the belt 233 is sleeved on the main pulley 231 and the slave pulley 232.
[0029] like Figure 1 As shown, the guide assembly 300 includes a guide shaft 310, a guide wheel 320 and a guide block 330. There are two guide shafts 310, which are installed in parallel at intervals on the front side of the frame 100. The guide wheel 320 is installed at the front end of the guide shaft 310, and the guide block 330 is installed at the front end of the leftmost guide shaft 310. A guide hole 331 is provided on the guide block 330. Through the setting of the guide block 330, the wire passes through the guide wheel 320 and exits from the guide hole 331, so that the direction of the wire is accurate, which meets the process requirements of accurate exit. Specifically, the guide block 330 is L-shaped; the aperture of the guide hole 331 is slightly larger than the diameter of the wire.
[0030] like Figure 1-Figure 3 As shown, the tension detection assembly 500 also includes a rotating shaft 520, a tension wheel 530, a counterweight 540 and a detector 550. The rotating shaft 520 is inserted through the frame 100 and rotates with the frame 100. The right end of the tension swing rod 510 is connected to the front end of the rotating shaft 520, and the left end thereof is connected to the tension wheel 530. The counterweight 540 is installed in the middle of the tension swing rod 510. The detector 550 is installed at the rear end of the rotating shaft 520 and is connected to the controller 400. Specifically, the detector 550 is an encoder, an angle sensor or a potentiometer, which is used to obtain the angle data of the rotation of the tension swing rod 510, wherein the encoder can identify slight angle changes and has higher sensitivity.
[0031] During operation, the wire drum (not shown in the figure) is mounted on the wire drum shaft 210, and then the wire is passed around the right guide wheel 320, the tension wheel 530 and the left guide wheel 320 in sequence, and then passes through the guide hole 331 and enters the wire drawing machine (not shown in the figure). Figure 4 As shown, at this time, the wire lifts the tension wheel 530 and does not contact the tension swing rod 510. Finally, the wire drawing machine pulls the wire, and at the same time, the controller 400 starts the motor 220 to drive the wire drum shaft 210 to rotate for active wire release. During the process, the detector 550 detects the rotation angle of the tension swing rod 510 and sends the relevant data (rotation direction and rotation angle) to the controller 400. The controller 400 controls the speed of the motor 220 according to the data, so that the tension of the wire remains consistent during the wire drum release process. When the tension of the wire is large, the tension wheel 530 will be lifted and the tension swing rod 510 will be driven to rotate clockwise. At this time, the controller 400 controls the motor 220 to speed up.
[0032] Example 2
[0033] This embodiment adds a sensor head 700 and a sensor 800 on the basis of the embodiment 1. Figure 5 As shown, the left end of the tension swing rod 510 is installed with a sensor head 700, and the front side of the frame 100 is installed with a sensor 800, the sensor head 700 corresponds to the sensor 800, and the sensor 800 is connected to the controller 400. Through the coordinated setting of the sensor head 700 and the sensor 800, when the silk thread is accidentally disconnected or the silk thread is used up, the tension swing rod 510 suddenly rotates counterclockwise quickly until it contacts the limit column 600, at which time the sensor head 700 contacts the sensor 800, and the sensor 800 sends a contact signal to the controller 400, and the controller 400 controls the motor 220 to stop to avoid subsequent disordered wire output or idling. Of course, an alarm light can also be added to the frame 100 to indicate that the silk thread is accidentally disconnected or the silk thread is used up.
