Description

Technical Field

[0001] This utility model relates to the field of wire feeding machine technology, and in particular to a wire feeding machine. Background Technology

[0002] A wire release machine is a device used to release wire from a reel. It is widely used in many fields such as wire and cable production, power engineering, and communication network construction to meet the needs of subsequent production or construction. The design and function of the wire release machine make it an indispensable piece of equipment in modern industrial production, which can significantly improve production efficiency and quality.

[0003] Meanwhile, existing wire feeding machines typically use tension sensors for individual monitoring. However, these sensors cannot fully reflect the dynamic changes during the wire feeding process when there are changes in roll diameter, speed, or emergency stops. This can lead to the wire becoming loose or breaking during the wire feeding process, affecting the stable operation of the wire feeding machine. Summary of the Invention

[0004] To overcome the problem that existing wire feeding machines typically use tension sensors for individual monitoring, which cannot fully reflect the dynamic changes during the wire feeding process when there are changes in roll diameter, speed, or emergency stops, leading to wire slack or breakage during the wire feeding process and affecting the stable operation of the wire feeding machine, this utility model provides a wire feeding machine.

[0005] The technical solution is as follows: A wire feeding machine includes a housing and a collection frame; collection frames are installed at both the front and rear ends of the housing; it also includes an I-beam wheel, a brake drum, a cylinder, an encoder, a linear speed sensor, a circular roller, an insulating column, and a copper clamp. The I-beam wheel is installed inside the housing, and an encoder is installed at one end of the I-beam wheel. A linear speed sensor is installed below the encoder. A connecting cable is provided between the linear speed sensor and the encoder. The linear speed sensor is electrically connected to the encoder through the connecting cable. Two sets of positioning frames are installed inside the housing, and a current detection module is installed inside the positioning frames.

[0006] Furthermore, a brake drum is installed on the outer end of the I-beam wheel, and a brake band is fitted between the brake drum and the I-beam wheel. A cylinder is fixed on one side of the I-beam wheel on the inner wall of the outer shell, and the cylinder is fixedly connected to the brake band.

[0007] Furthermore, a lead screw is fixed to the inner wall of the housing above the cylinder. A spring is installed at one end of the lead screw, and a spring rubber damper is installed inside the spring. One end of the lead screw is fixedly connected to the brake band, and a handwheel is installed at the end of the lead screw away from the brake band on the outer side of the housing.

[0008] Furthermore, positioning blocks are symmetrically installed on the upper end of the outer shell, and round rollers are installed on the inner side of the positioning blocks. An insulating column is installed on one side of the round rollers, and a connecting block is fixed to the upper end of the insulating column.

[0009] Furthermore, a connecting rod is fixed inside the connecting block, and a fixing ring is sleeved on the outer end of the connecting rod. Two sets of copper clips are installed at the lower end of the fixing ring, and connecting springs are installed inside the two sets of copper clips. The connecting springs are fixedly connected to the lower end of the fixing ring.

[0010] Furthermore, carbon brushes are installed on the inner walls of the two sets of copper clips, and the carbon brushes are fitted into the circular rollers. The two sets of copper clips are electrically connected to the current detection module.

[0011] Furthermore, a protective cover is installed on the outer wall of the outer casing, and two sets of hinges are installed between the protective cover and the outer casing. The protective cover is movably set along the outer wall of the outer casing through the two sets of hinges.

[0012] Furthermore, a drive motor is installed inside the outer casing at the end away from the I-beam wheel, and one end of the drive motor is fixedly connected to the positioning frame.

[0013] The beneficial effects are: This utility model realizes the synchronous monitoring of the operation of the wire feeding machine by using an encoder and a linear speed sensor. The encoder can accurately measure the speed and position information of the motor, provide high-precision feedback signals, monitor the operating status of the wire feeding machine in real time, ensure the precise control of the wire feeding speed and tension, and the synchronous monitoring can accurately calculate the remaining winding diameter of the I-beam and adjust the tension of the wire feeding machine in real time to achieve constant tension wire feeding and avoid the wire from becoming loose or breaking during the wire feeding process;

[0014] By using a linear velocity sensor, the speed of the pay-off machine can be automatically reduced when the roll diameter decreases, ensuring that the steel strip release process maintains a constant linear velocity, reducing the risk of strip breakage caused by inertial impact, and ensuring the stable operation of the pay-off machine;

[0015] By utilizing the current detection module, the control equipment can be immediately stopped when power is lost, and a new I-beam shaft can be quickly replaced, achieving uninterrupted production, reducing downtime caused by steel strip replacement, and improving production efficiency.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-4 As shown, a wire feeding machine has collection frames 2 installed at both the front and rear ends of the outer casing 1; it also includes a bobbin 3, a brake drum 5, a cylinder 7, an encoder 9, a linear velocity sensor 10, a circular roller 11, an insulating column 13, and a copper clamp 17. The bobbin 3 is installed inside the outer casing 1, and the encoder 9 is installed at one end of the bobbin 3. The linear velocity sensor 10 is installed below the encoder 9, and a connecting cable is provided between the linear velocity sensor 10 and the encoder 9. The linear velocity sensor 10 is electrically connected to the encoder 9 through the connecting cable. Two sets of positioning devices are installed inside the outer casing 1. The frame 22 has a current detection module installed inside. A brake drum 5 is installed on the outer end of the I-beam wheel 3. A brake band 4 is fitted between the brake drum 5 and the I-beam wheel 3. A cylinder 7 is fixed on one side of the I-beam wheel 3 on the inner wall of the outer casing 1. The cylinder 7 is fixedly connected to the brake band 4. A lead screw 6 is fixed on the inner wall of the outer casing 1 above the cylinder 7. A spring is installed on one end of the lead screw 6. A spring rubber damper is installed inside the spring. One end of the lead screw 6 is fixedly connected to the brake band 4. A handwheel 8 is installed on the outer side of the outer casing 1 at the end of the lead screw 6 away from the brake band 4.

[0024] Please see Figures 2-4 In this embodiment, positioning blocks 12 are symmetrically installed on the upper end of the outer shell 1. A circular roller 11 is installed on the inner side of the positioning block 12. An insulating post 13 is installed on one side of the circular roller 11. A connecting block 14 is fixed at the upper end of the insulating post 13. A connecting rod 15 is fixed inside the connecting block 14. A fixing ring 16 is sleeved on the outer end of the connecting rod 15. Two sets of copper clips 17 are installed at the lower end of the fixing ring 16. A connecting spring is installed inside the two sets of copper clips 17. The connecting spring is fixedly connected to the lower end of the fixing ring 16. Carbon brushes 18 are installed on the inner wall of the two sets of copper clips 17. The carbon brushes 18 are fitted with the circular roller 11. The two sets of copper clips 17 are electrically connected to the current detection module.

[0025] Please see Figures 3-5In this embodiment, a protective cover 19 is installed on the outer wall of the outer shell 1, and two composite hinges 20 are installed between the protective cover 19 and the outer shell 1. The protective cover 19 is movably arranged along the outer wall of the outer shell 1 through the two composite hinges 20. A drive motor 21 is installed at the end of the outer shell 1 away from the I-beam wheel 3. One end of the drive motor 21 is fixedly connected to the positioning frame 22.

[0026] During the operation of the wire feeding machine, the required wire is first installed inside the housing 1 via the positioning frame 22. The drive motor 21 is started and connected to the positioning frame 22 to rotate and release the wire. During the rotation and release of the wire, the encoder 9 is used to accurately measure the motor speed and position information, providing high-precision feedback signals. At the same time, the linear speed sensor 10 monitors the wire feeding speed to ensure that the wire is released at a constant speed. The synchronous monitoring of both can accurately calculate the remaining winding diameter of the I-beam and adjust the tension of the wire feeding machine in real time to achieve constant tension wire feeding and prevent the wire from becoming slack or breaking during the wire feeding process. When it is necessary to stop the wire feeding or perform an emergency braking, the cylinder 7 is used to drive the brake. The brake band 4 is tightly attached to the brake drum 5, and the friction prevents the rotation of the I-beam 3, achieving rapid braking. The tension of the brake band 4 can be adjusted by the screw 6 via the handwheel 8. The spring and spring rubber damper provide a buffering effect, reducing the impact and vibration during braking. The carbon brush 18 is tightly attached to the circular roller 11 and slides as the circular roller 11 rotates to collect or transmit current signals. The current detection module monitors the working current of the wire feeding machine. In the event of a power failure, the current detection module immediately triggers the emergency stop mechanism to stop the equipment from running, so as to quickly replace the new I-beam shaft, reduce downtime, achieve uninterrupted production, and ensure the normal operation of the equipment.
