Description

Technical Field

[0001] The invention belongs to the technical field of wire packaging equipment, and in particular relates to a four-point tie device with a compact structure. Background Art

[0002] In the production process of civil wires, after the wires are coiled by the shaking plate coiling machine, they need to go through processes such as four-point tie or winding film to achieve the shaping and fixation of the coils. For coils that require four-point tie, they are usually bundled at four equal positions in the circumferential direction of the coil (see Figure 1 ), the equipment to achieve this function consists of a front arm device, a one-point and two-point cable tie machine, a turntable, a rear arm device, and a three-point and four-point cable tie machine. Each component is placed on the same center line in sequence. The working steps of the four-point cable tie (see Figure 2 ) is: the coil after the shaking plate coil forming machine is coiled is held tightly by the front arm device and moved right along the center line of the equipment to the one-two point tie machine, so that the right half of the coil is within the tie range, the one-two point tie machine moves to achieve the first point tie, the front arm device holds the coil and continues to move right along the center line of the equipment, so that the left half of the coil is within the tie range, the one-two point tie machine moves to achieve the second point tie, at this time the one-two point tie is distributed at 180°, the front arm device holds the coil and continues to move right along the center line of the equipment to hold the coil to On the turntable, the front arm device returns to the original position and waits for the next coil to be held. At the same time, the turntable drives the coil to rotate 90°. The rear arm device takes the coil from the turntable and moves right along the center line of the equipment to the three- and four-point tie-tying machines, so that the right half of the coil is within the tie-tying range. The three- and four-point tie-tying machines are actuated to achieve the third-point tie-tying. The rear arm device continues to move right with the coil, so that the left half of the coil is within the tie-tying range. The three- and four-point tie-tying machines are actuated to achieve the fourth-point tie-tying. At this point, the four-point tie-tying is completed and the four points are evenly distributed in the circumferential direction. Then, the rear arm device continues to move right along the center line of the equipment, and holds the coil that has completed the four-point tie-tying to the conveyor belt. The rear arm releases the coil and moves left to reset, ready to hold the next coil. This cycle works in this way to achieve the function of the equipment. This equipment layout is distributed in a row along the center line (see Figure 4 ), occupies a large space, and a turntable is required between the one-point and two-point cable tie machines and the three-point and four-point cable tie machines. Therefore, the single-step time is long, the production efficiency is low, and the rotation position of the turntable requires high accuracy. Summary of the invention

[0003] In order to solve the above problems, the present invention proposes a four-point cable tie device with a compact structure.

[0006] The top of the frame is equipped with a front arm device, a one-point and two-point tie-tie machine, a rear arm device, a three-point and four-point tie-tie machine in sequence. The one-point and two-point tie-tie machines and the three-point and four-point tie-tie machines are installed in a vertical position, and the two tie-tie machines are close together.

[0007] The front arm device is used to move the coil to the one-point or two-point cable tie machine position, and the rear arm device is used to move the coil to the three-point or four-point cable tie machine.

The swing arm is hinged to the top of the cross slide through the arm shaft. The double-axis cylinder is fixedly connected to the top of the cross slide. The double-axis cylinder is used to drive the swing arm to rotate around the arm shaft. When the coil needs to be clamped, the double-axis cylinder is electrically controlled to intake air into the cylinder body, and the piston shafts on both sides extend outward, pushing the two swing arms to rotate towards each other around the arm shaft, thereby clamping the coil. When the cylinder body is exhausted, the piston shafts on both sides retract inward, and the two swing arms rotate in opposite directions around the arm shaft under the action of the tension spring, thereby loosening the coil.

[0010] Preferably, the cross slide is provided with a transverse slide rail and a longitudinal slide rail, the transverse slide rail is fixedly connected to the frame, the longitudinal slide rail slides on the top of the transverse slide rail, the center line of the transverse slide rail and the frame is parallel, the center line of the longitudinal slide rail and the frame is perpendicular, the top of the longitudinal slide is slidably connected to a support plate, the swing arm is installed on the top of the support plate, the cross slide provides guidance and power for the swing arm to move left and right and forward and backward, the swing arm is provided with two symmetrical groups, which are respectively hinged by the arm rotating shaft and the support plate, and a tension spring is fixedly connected between the inner ends of the swing arms on both sides.

Two synchronous belts are movably connected to the two sides of the mobile drive system, and the two synchronous belts are fixedly connected to the holding block mounting seats on both sides respectively.

[0013] Preferably, when the synchronous pulley of the mobile drive system rotates forward and reversely, the two synchronous belts drive the holding block mounting seats and the holding blocks on both sides to move left and right along the guide rail. When air is taken in the compression chamber of the cylinder, the piston rod extends to push the holding block toward the center line of the equipment. When air is taken in the contraction chamber of the cylinder, the piston rod retracts to drive the holding block away from the center line of the equipment.

[0014] Preferably, the three-point and four-point cable tie machines have the same structure as the one-point and two-point cable tie machines, and the three-point and four-point cable tie machines and the one-point and two-point cable tie machines are both standard sword-piercing cable tie machines.

[0015] Compared with the prior art, the present invention has the following beneficial effects: compact structure design and reliable function.

[0016] The directions of coil movement are perpendicular to each other when tying at one or two points and at three or four points, and the installation positions of the two tie machines are also vertical, which ensures the even division accuracy of the four-point tie positions. The two tie machines are close together, which shortens the distance the coil moves during the tie process and reduces the time required. There is no need for a turntable between the two tie machines, which further simplifies the equipment and shortens the working time of a single piece. Therefore, the device has significant reliability and advancement. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] refer to Figure 7, wherein the front arm device 2 includes a cross slide 6, a swing arm 7, an arm shaft 8, a double-axis cylinder 9 and a tension spring 10. The cross slide 6 is fixedly installed on the top of the frame 1 by bolts. The top of the cross slide 6 is movably connected with a swing arm 7. The swing arm 7 is provided with two symmetrical groups. The swing arm 7 is hinged on the top of the cross slide 6 through the arm shaft 8. The double-axis cylinder 9 is fixedly connected to the top of the cross slide 6. The double-axis cylinder 9 is used to drive the swing arm 7 to rotate around the arm shaft 8. When the coil 18 needs to be tightened, the double-axis cylinder 9 is electrically controlled to take air into the cylinder body, and the piston shafts on both sides extend outward, pushing the two swing arms 7 to rotate in opposite directions around the arm shaft 8, thereby tightening the coil 18. When the cylinder body is exhausted, the piston shafts on both sides retract inward, and the two swing arms 7 rotate in the opposite direction around the arm shaft 8 under the action of the tension spring 10, thereby loosening the coil 18. It is used to fix the mobile coil 18 in the first binding process.
