Description

Technical Field

[0001] This utility model relates to the field of wire feeding frame technology for wire feeding machines, and in particular to a wire feeding frame for wire feeding machines that prevents wire breakage. Background Technology

[0002] The wire feeding frame of the wire drawing machine, also known as the multi-head wire drawing reel double-head power feeding machine, double-head wire feeding frame, power feeding frame, etc., is a device that is matched with the multi-head wire drawing machine. It is an important component of the wire and cable manufacturing equipment. It is specially used for multi-strand wire feeding operations or single-strand feeding operations of the stranding machine. It is widely used in the wire and cable manufacturing industry, especially in the metal shielding outer mesh layer braiding operation of fine wire high-speed braiding machines.

[0003] Patent application number 202322424476.5 discloses a wire feeding frame for a wire-breaking prevention twinning machine, including a fixed base frame and several wire feeding blocks installed on the fixed base frame; characterized in that a movable guide is detachably installed on the fixed base frame; a spring is installed between each wire feeding block and the fixed base frame; the movable guide includes an elastic sleeve and a guide rod rotatably installed on the elastic sleeve.

[0004] However, in the production environment, the air often contains many dust particles, fibers, metal shavings and other debris. When the wire feeding frame of the wire feeding machine is exposed to such an environment for a long time, these debris can easily adhere to the surface of the wire hole and gradually accumulate. In addition, if the operation is improper during the feeding process, such as excessive tension of the wire or excessive speed, the friction between the wire and the wire hole may increase, thereby accelerating the accumulation of dust and debris, which will hinder the smooth passage of the wire, and may even cause the wire to get stuck or break.

[0005] For example, dust and debris may contain hard particles. These particles will rub against components such as wire holes, wire holes and shafts when the equipment is running. Prolonged friction will cause wear on the surface of the components and may even damage the components, affecting the normal operation and service life of the equipment. Utility Model Content

[0006] This utility model discloses a wire feeding rack for a wire drawing machine to prevent wire breakage. It aims to solve the technical problem that in the production environment, the air often contains many dust particles, fibers, metal shavings and other debris. When the wire feeding rack of the wire drawing machine is exposed to such an environment for a long time, these debris can easily adhere to the surface of the wire hole and gradually accumulate. In addition, if the operation is not done properly during the wire feeding process, such as excessive tension of the wire or excessive speed, the friction between the wire and the wire hole may increase, thereby accelerating the accumulation of dust and debris, which will hinder the smooth passage of the wire, and may even cause the wire to get stuck or break.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A wire feeding frame for a wire-breaking prevention device includes a base frame, a mounting bracket on the top outer wall of the base frame, and a fixing rod inside the base frame. It also includes:

[0009] Cleaning mechanism: Located on one side of the fixed rod, the cleaning mechanism includes six first guide rings, six second guide rings, and six mounting plates. Two limiting grooves are formed on the outer circumference of the first guide rings. Two sliders are provided on the inner circumference of the second guide rings, and the sliders are slidably connected to the inner wall of the limiting grooves. A guide hole is formed between the first and second guide rings. The mounting plate is mounted on the inner circumference of the first guide rings. A mounting groove is formed on the top outer wall of the mounting plate, and a movable plate is slidably connected to the inner wall of the mounting groove. Several cleaning brushes are provided on the bottom outer wall of the movable plate. Movable components are provided on the outer circumference of the first guide rings. Adjustment mechanism: Located on one side of the base frame.

[0010] The above technical solution reduces wire jamming and breakage, extends equipment lifespan, and improves wire twisting quality. Specifically, during operation, the wire to be twisted passes through the wire hole formed by the first and second guide rings. As the wire is released, the moving plate moves back and forth along the mounting groove, allowing the cleaning brush on the moving plate to clean the inner circumference of the first guide ring. Then, a fan draws external air into the mounting pipe and delivers it to the top of the second guide ring via a connecting pipe, blowing away the dust scraped off by the cleaning brush from top to bottom. This design prevents the wire from directly contacting the inner wall of the first guide ring and causing friction that could lead to breakage. It also reduces the accumulation of metal debris and dust particles on the inner wall of the first guide ring. The connecting rod can be adjusted according to the direction of wire movement to prevent breakage during twisting. The first and second guide rings can slide relative to each other through the cooperation of a slider and a limiting groove to accommodate wires of different diameters, while the wire hole formed between them allows the wire to pass through.

[0011] In a preferred embodiment, the adjusting mechanism includes three connecting frames. One outer wall of each connecting frame is connected to a limiting plate via a bearing. One outer wall of the limiting plate has four mounting holes. Four return springs are provided on the inner circumference of each mounting hole. One end of each return spring is fixedly connected to a clamping plate. A limiting component is provided on one outer wall of the limiting plate.

[0012] In this design, the clamping and fixing of the wire is achieved through the combined action of the clamping plate and the return spring. The clamping plate fits tightly against the wire, while the return spring provides a certain elastic force, ensuring that the clamping plate can elastically deform when subjected to external force and automatically return to its original position after the external force disappears, thus maintaining stable clamping of the wire. When the clamping plates in two of the mounting holes become worn, the limiting assembly can be opened, and then the other two mounting holes on the limiting plate can be rotated to the positions corresponding to the wire holes, thereby extending the service life of the entire adjustment mechanism. The combined action of the clamping plate and the return spring ensures the stability of the wire during the wire release process, reducing the risk of wire breakage due to shaking or detachment.

[0013] In a preferred embodiment, the limiting assembly includes six threaded posts, six connecting grooves are provided on one outer wall of the base frame, four limiting openings are provided on one outer wall of the limiting plate, one end of each threaded post penetrates the inner wall of the limiting opening, and the other end of each threaded post is threadedly connected to the inner wall of the connecting groove.

[0014] In this design, the limiting plate is connected to the base frame by a threaded post, which ensures that the limiting plate will not move or rotate due to external force after the position is adjusted. When it is necessary to replace the worn clamp or return spring, the user can easily loosen the threaded post, rotate the limiting plate to the appropriate position, and then tighten the threaded post again to fix it.

[0015] As described above, a wire feeding frame for a wire-breaking prevention twinning machine includes a base frame, a mounting bracket on the top outer wall of the base frame, and a fixing rod inside the base frame. It also includes: a cleaning mechanism located on one side of the fixing rod, comprising six first guide rings, six second guide rings, and six mounting plates. The outer circumference of each first guide ring has two limiting grooves, and the inner circumference of each second guide ring has two sliders slidably connected to the inner wall of the limiting grooves. A wire hole is formed between the first and second guide rings. The mounting plates are mounted on the inner circumference of the first guide rings. The top outer wall of the mounting plate has a mounting groove, and a movable plate is slidably connected to the inner wall of the mounting groove. The bottom outer wall of the movable plate has several cleaning brushes. A movable component is located on the outer circumference of each first guide ring. An adjustment mechanism is also provided on one side of the base frame. This wire feeding frame for a twinning machine provides the technical effect of reducing wire jamming or breakage, extending the service life of the equipment, and improving the quality of twinning.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] The wire feeding rack of the wire drawing machine disclosed in this utility model is mainly used in production environments where the air often contains many dust particles, fibers, metal shavings and other debris. When the wire feeding rack of the wire drawing machine is exposed to such an environment for a long time, these debris can easily adhere to the surface of the wire hole and gradually accumulate. In addition, if the operation is improper during the wire feeding process, such as excessive tension of the wire or excessive speed, the friction between the wire and the wire hole may increase, thereby accelerating the accumulation of dust and debris, which will hinder the smooth passage of the wire, and may even lead to the wire getting stuck or breaking.

[0023] Reference Figure 1 and Figure 2A wire feeding frame for a wire-breaking prevention device includes a base frame 1, a mounting bracket 2 on the top outer wall of the base frame 1, and a fixing rod 3 inside the base frame 1. It also includes: a cleaning mechanism located on one side of the fixing rod 3, comprising six first guide rings 12, six second guide rings 13, and six mounting plates 16. The outer circumference of each first guide ring 12 has two limiting grooves 15, and the inner circumference of each second guide ring 13 has two sliders 14 slidably connected to the inner wall of the limiting grooves 15. A wire hole is formed between the first guide rings 12 and the second guide rings 13. The mounting plates 16 are mounted on the inner circumference of the first guide rings 12. The top outer wall of the mounting plates 16 has a mounting groove 17, and a movable plate 18 is slidably connected to the inner wall of the mounting groove 17. The bottom outer wall of the movable plate 18 has several cleaning brushes, and the outer circumference of each first guide ring 12 has movable components. An adjustment mechanism is also located on one side of the base frame 1.

[0024] It should be noted that the mounting plate 16 is fixed to the front and rear sides of the first guide ring 12 by screws. This arrangement facilitates quick replacement when the moving plate 18 or cleaning brush is worn, extends the service life of the first guide ring 12, and avoids wear caused by direct contact between the inner wall of the first guide ring 12 and the wire.

[0025] The movable component includes six elastic sleeves 4 and a connecting rod 11 hinged to the elastic sleeves 4. The elastic sleeves 4 are fitted onto the outer circumferential wall of the fixed rod 3. This arrangement allows the connecting rod 11 to make slight directional adjustments during the wire feeding process, which helps maintain the stability and tension of the conductor and prevents the wire from breaking during the wire feeding process. The elasticity of the elastic sleeves 4 can also absorb the vibration and impact generated during the wire feeding process, further protecting the conductor from damage.

[0026] In the specific implementation process, the movable plate 18 has an arc-shaped structure. The design of the arc-shaped movable plate 18 allows it to fit more closely to the shape of the line. This fit helps to reduce the gap between the line and the movable plate 18, thereby reducing the risk of wear and damage to the wire feeding frame, and helping to extend the service life of the equipment and reduce maintenance costs.

[0027] The mounting frame 2 has a mounting frame 19 on one side of its outer wall. A fan 20 is fixedly connected to the bottom inner wall of the mounting frame 19. A mounting pipe 21 is provided at the air outlet of the fan 20. An air inlet is provided on the outer circumference of the second guide ring 13. A connecting pipe 22 is provided on the inner wall of the air inlet. One end of the connecting pipe 22 is connected to the inner circumference of the mounting pipe 21. When the fan 20 is started, the airflow generated enters the connecting pipe 22 through the mounting pipe 21 and is ejected from the air inlet of the second guide ring 13. The airflow can blow away dust, fibers and other impurities attached to the second guide ring 13 and its surrounding area, thereby keeping the pay-off frame clean. Especially when used in conjunction with the moving plate 18 and the cleaning brush, the airflow can more effectively blow away the scraped dust and impurities. During long-term operation, the pay-off frame and the wire may generate heat due to friction and current flow. The airflow of the fan 20 can carry away this heat, thereby reducing the temperature of the pay-off frame and the wire and preventing damage or wire breakage caused by overheating.

[0028] Specifically, during the use of the wire-splitting machine, the wire to be split passes through the wire hole formed by the first guide ring 12 and the second guide ring 13. Then, as the wire is released, the moving plate 18 moves back and forth along the mounting groove 17. The cleaning brush on the moving plate 18 cleans the inner circumference of the first guide ring 12. Then, the blower 20 is turned on, drawing external air into the mounting pipe 21, and then transporting it through the connecting pipe 22 to the top of the second guide ring 13. This blows away the dust scraped off by the cleaning brush from top to bottom, preventing the wire from directly contacting the first guide ring 13. The direct contact between the inner wall of the conductor ring 12 and the conductor ring 13 generates friction that can cause wire breakage. At the same time, it can also reduce the accumulation of metal debris and some dust particles on the inner wall of the first conductor ring 12. The connecting rod 11 can be adjusted according to the direction of wire movement to prevent wire breakage during the wire twisting process. The first conductor ring 12 and the second conductor ring 13 can slide relative to each other through the cooperation of the slider 14 and the limiting groove 15 to accommodate wires of different diameters. At the same time, the conductor hole formed between them allows the wire to pass through. This device can reduce wire jamming or breakage, extend the service life of the equipment, and improve the quality of wire twisting.

[0029] Reference Figure 1 and Figure 4 In a preferred embodiment, the adjustment mechanism includes three connecting frames 5. One outer wall of the connecting frame 5 is connected to a limiting plate 6 via a bearing. One outer wall of the limiting plate 6 has four mounting holes. Four return springs 8 are provided on the inner circumference of the mounting holes. One end of the return spring 8 is fixedly connected to a clamping plate 9. A limiting component is provided on one outer wall of the limiting plate 6.

[0030] The four mounting ports are symmetrically distributed about the connecting frame 5.

[0031] Specifically, the clamping and fixing of the wire is achieved through the cooperation of the clamping plate 9 and the return spring 8. The clamping plate 9 can fit tightly against the wire, while the return spring 8 provides a certain elastic force, ensuring that the clamping plate 9 can elastically deform when subjected to external force and automatically return to its original position after the external force disappears, thereby maintaining stable clamping of the wire. When the clamping plates 9 in two of the mounting holes become worn, the limiting assembly can be opened, and then the other two mounting holes on the limiting plate 6 can be rotated to the positions corresponding to the wire holes, thereby extending the service life of the entire adjustment mechanism. The cooperation of the clamping plate 9 and the return spring 8 ensures the stability of the wire during the wire release process and reduces the risk of wire breakage caused by shaking or falling off.

[0032] During the wire feeding process, the wire feeding frame can also be equipped with tension adjustment devices such as adjustment frames and nut seats to adjust the tension of the wire. By adjusting the tension adjustment, users can maintain the consistency of the wire tension during the wire feeding process, thereby improving the wire feeding quality.

[0033] Reference Figure 1 and Figure 3 In a preferred embodiment, the limiting component includes six threaded posts 10, six connecting grooves are provided on one outer wall of the base frame 1, four limiting ports 7 are provided on one outer wall of the limiting plate 6, one end of the threaded post 10 passes through the inner wall of the limiting port 7, and one end of the threaded post 10 is threadedly connected to the inner wall of the connecting groove.

[0034] Specifically, by connecting the limiting plate 6 to the base frame 1 through the threaded post 10, it can be ensured that the limiting plate 6 will not move or rotate due to external force after the position is adjusted. When it is necessary to replace the worn clamping plate 9 or the return spring 8, the user can easily loosen the threaded post 10, rotate the limiting plate 6 to the appropriate position, and then tighten the threaded post 10 again to fix it.

[0035] Working principle: During use, the wire to be wired passes through the wire hole formed by the first guide ring 12 and the second guide ring 13. As the wire is released, the moving plate 18 moves back and forth along the mounting groove 17. The cleaning brush on the moving plate 18 cleans the inner circumference of the first guide ring 12. Then, the blower 20 is turned on, and the blower 20 draws external air into the mounting pipe 21, and then delivers it to the top of the second guide ring 13 through the connecting pipe 22. This blows away the dust scraped off by the cleaning brush from top to bottom. This design prevents the wire from directly contacting the inner wall of the first guide ring 12 and causing friction that could break the wire. It also reduces the accumulation of metal shavings and dust particles on the inner wall of the first guide ring 12. The connecting rod 11 can be adjusted according to the direction of wire movement to prevent the wire from breaking during the wire spinning process. The first guide ring 12 and the second guide ring 13 can slide relative to each other through the cooperation of the slider 14 and the limiting groove 15 to accommodate wires of different diameters.

[0036] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
