Description

Technical Field

[0001] This utility model relates to the field of untwisting machine technology, specifically a vertical untwisting machine. Background Technology

[0002] A wire untwisting machine is a device used for untwisting cables, ropes, and other products. Its main function is to eliminate torsional stress caused by the twisting or rotation process, restoring the cable to its original shape and preventing excessive twisting from affecting its performance, lifespan, and safety. It is widely used in the power, telecommunications, and communications industries, improving production efficiency, ensuring product quality, improving appearance, and enhancing cable stability. The structure of a wire untwisting machine mainly includes an infeed system, an untwisting device, a tension control system, an outfeed system, and an electrical control system. The untwisting machine, through the coordinated action of mechanical devices and a tension control system, gradually releases the internal stress of the cable after it has undergone reverse torque or tension adjustment, restoring it to an ideal state. For example, a vertical network cable untwisting machine disclosed in authorization announcement number CN216054048U includes a support frame, anchor holes, a bearing plate, a wheel, a first annular toothed groove, an internal toothed transmission belt, a large circular hole, a protective ring, a second annular toothed groove, an annular block, a cylinder, small circular holes, ball bearings, perforations, a disc, steel balls, a column hole, and a motor. Multiple small circular holes are set on the end face of the cylinder, and perforated ball bearings are installed within these small holes. This method can pass network cables through perforations and reduce cable wear, making it suitable for untwisting network cables with multiple branches. However, during use, the cables themselves have a certain degree of flexibility and deformability. Since the cables are not pulled or guided in a distributed manner, they are subjected to uneven tension and torque during radial stress and untwisting. This uneven force can cause the cables to bend, twist, or even collide or knot. When the cables collide or knot, it not only interrupts the production process but also leads to instability in the untwisting effect, thereby increasing the time for rework and adjustment. Utility Model Content

[0003] The purpose of this utility model is to provide a vertical untwisting machine, which sets up a wire pressing mechanism and an anti-deviation structure in the wire feeding frame to guide the wire to be untwisted into the belt-type untwisting structure. After being untwisted by the belt-type untwisting structure, the wire is pulled out by the roller-type wire feeding structure, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vertical untwisting machine, comprising a wire feeding frame and a wire support platform fixed at the top of the wire feeding frame, wherein a wire pressing mechanism for upper-positioning the cable in the Z-axis direction is installed on the top of the wire feeding frame on one side of the wire support platform; an anti-deviation structure providing lateral support force to the wire is provided on the upper surface of the wire feeding frame; a roller-type wire feeding structure for pulling the wire to move in the X-axis direction is provided on the outer wall of the wire feeding frame away from the wire pressing mechanism; a belt-type untwisting structure is provided inside the wire feeding frame between the roller-type wire feeding structure and the anti-deviation structure; a bevel gear drive unit for driving the belt-type untwisting structure and the roller-type wire feeding structure to work synchronously is installed on the outer wall of the wire feeding frame on one side of the roller-type wire feeding structure; and a PLC control panel electrically connected to the input end of the bevel gear drive unit is installed on one side of the back of the wire feeding frame.

[0005] Preferably, the wire pressing mechanism includes a U-shaped frame mounted on one side of the top of the wire feeder, a cylinder mounted on the top of the U-shaped frame, and a lower rubber seat fixed to the bottom of the cylinder piston rod, the lower rubber seat being located above the wire support platform.

[0006] Preferably, the anti-deviation structure includes two guide posts installed in parallel on the upper surface of the wire feeder and several partition plates slidably installed on the surfaces of the two guide posts.

[0007] Preferably, the belt-type unwinding structure includes an upper belt unwinding structure, a lower belt unwinding structure disposed inside the wire feeder, and a belt drive structure between the upper belt unwinding structure and the lower belt unwinding structure for maintaining power connection.

[0008] Preferably, the roller-type wire feeding structure includes two rubber rollers rotatably mounted inside one side of the wire feeding frame and a gear disk fixed at the same end of the two rubber rollers. The two gear disks fit together, and the bevel gear drive unit is used to drive one of the rubber rollers and the upper belt unwinding structure to work synchronously.

[0009] Preferably, the bevel gear drive unit includes a stepper motor mounted on the outer wall of one side of the wire feeder and a bevel gear transmission structure mounted on the output end of the stepper motor for driving the rubber roller and the upper belt unwinding structure to work synchronously. The input end of the stepper motor is electrically connected to the output end of the PLC control panel.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This vertical untwisting machine feeds the wire through a wire feeding frame, and the wire support table provides support to prevent the wire from sagging or twisting. The wire pressing mechanism and the anti-deviation structure provide appropriate pressure and guidance to ensure that the wire smoothly enters the belt-type untwisting structure. During the untwisting process, the belt-type untwisting device releases the torque of the wire, allowing the wire to return to its normal state. Subsequently, through the traction of the roller-type wire feeding structure, the wire is stably transported to the next process. The wire pressing mechanism prevents the wire from swaying or deviating irregularly due to gravity or inertia during the transport process, while the anti-deviation structure effectively prevents the wire from shifting laterally, ensuring that the wire always stays on the correct path. This reduces resistance and instability factors during the wire feeding process, ensuring the accuracy and consistency of the untwisting effect. Furthermore, with the guidance of the wire pressing mechanism and the anti-deviation structure, the wire can accurately enter the belt-type untwisting structure, making the contact between the belt and the wire more uniform and stable, thereby improving the untwisting efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figure 1-5 An embodiment of this utility model provides a vertical untwisting machine, including a wire feeder 1 and a wire support platform 2 fixed at the top of the wire feeder 1. A wire pressing mechanism 3 for upper limit positioning of the cable in the Z-axis direction is installed on the top of the wire feeder 1 on one side of the wire support platform 2. An anti-deviation structure 4 for providing lateral support force to the wire is provided on the upper surface of the wire feeder 1. A roller-type wire feeding structure 6 for pulling the wire to move in the X-axis direction is provided on the outer wall of the wire feeder 1 away from the wire pressing mechanism 3. A belt-type untwisting structure is provided inside the wire feeder 1 between the roller-type wire feeding structure 6 and the anti-deviation structure 4. A bevel gear drive unit 5 for driving the belt-type untwisting structure and the roller-type wire feeding structure 6 to work synchronously is installed on the outer wall of the wire feeder 1 on one side of the roller-type wire feeding structure 6. A PLC control panel 10 electrically connected to the input end of the bevel gear drive unit 5 is installed on one side of the back of the wire feeder 1.

[0019] The wire pressing mechanism 3 includes a U-shaped frame 301 mounted on one side of the top of the wire feeding frame 1, a cylinder 302 mounted on the top of the U-shaped frame 301, and a lower rubber seat 303 fixed at the bottom of the piston rod of the cylinder 302. The lower rubber seat 303 is located above the wire support table 2. When the wire pressing mechanism 3 is working, the operator uses the PLC control panel 10 to start the cylinder 302. The cylinder 302 drives the lower rubber seat 303 to move down, so that the lower surface of the lower rubber seat 303 contacts the cable to reduce the amount of runout of the cable on the Z-axis.

[0020] The anti-deviation structure 4 includes two guide posts that are installed in parallel on the upper surface of the wire feeder 1 and several partition plates that are slidably installed on the surfaces of the two guide posts;

[0021] The belt-type unwinding structure includes an upper belt unwinding structure 7, a lower belt unwinding structure 8, and a belt drive structure 9 for maintaining power connection between the upper belt unwinding structure 7 and the lower belt unwinding structure 8, which are installed inside the wire feeder 1. The wire, after being suppressed by the wire pressing mechanism 3 and the anti-deviation structure 4, enters between the upper belt unwinding structure 7 and the lower belt unwinding structure 8. The stepper motor 501 drives the upper belt unwinding structure 7 to rotate first, and then the upper belt unwinding structure 7 drives the lower belt unwinding structure 8 to rotate together through the belt drive structure 9. The belts of the two belts generate friction through contact with the wire, eliminating the torque of the wire and restoring the wire to a near-straight state.

[0022] The roller-type wire feeding structure 6 includes two rubber rollers 601 rotatably mounted inside one side of the wire feeding frame 1 and a gear disk 602 fixed at the same end of the two rubber rollers 601. The two gear disks 602 fit together. The bevel gear drive unit 5 is used to drive one of the rubber rollers 601 and the upper belt unwinding structure 7 to work synchronously. The bevel gear drive unit 5 includes a stepper motor 501 mounted on the outer wall of one side of the wire feeding frame 1 and a bevel gear transmission structure 502 mounted on the output end of the stepper motor 501 to drive the rubber roller 601 and the upper belt unwinding structure 7 to work synchronously. The input end of the stepper motor 501 is electrically connected to the output end of the PLC control panel 10.

[0023] After the untwisted wire is introduced between the two rubber rollers 601, the rotational power of the stepper motor 501 is transmitted to one of the rubber rollers 601 through the bevel gear transmission structure 502. Then, the two rubber rollers 601 rotate synchronously in opposite directions under the drive of the gear disk 602, so that the untwisted wire is drawn out.

[0024] In this embodiment, the operator first guides multiple untwisted wires from between the wire support platform 2 and the wire pressing mechanism 3 to the wire feeder 1, and then guides the wires from the anti-deviation structure 4 into the belt-type untwisting structure. The wire support platform 2 provides necessary support to prevent the wires from sagging or becoming excessively twisted during transport. The wire pressing mechanism 3 applies pressure to the wires to maintain their stability during transport, preventing unnecessary Z-axis swaying or deviation due to inertia or other external forces. The anti-deviation structure 4 uses lateral support to prevent lateral deviation between adjacent wires, ensuring that the wires accurately enter the subsequent untwisting structure. Then, the operator uses P... When the LC control panel 10 starts the bevel gear drive unit 5, the bevel gear drive unit 5 provides power to the belt-type untwisting structure and the roller-type wire feeding structure 6. The main function of the belt-type untwisting structure is to release the torque in the wire through friction, thereby restoring the wire to a straight state. After being untwisted by the belt-type untwisting structure, the wire usually becomes straighter and smoother, but it still needs further traction and conveying to ensure that it can smoothly enter the subsequent process. The roller-type wire feeding structure 6 uses a pair of rollers to pull the wire and maintain the continuous flow of the wire. That is, the clamping force and friction between the two rollers make the wire pass through the entire wire feeding system stably, ensuring that the wire can be smoothly delivered to the next process, such as shearing and stretching.
