Description

Technical Field

[0001] This invention relates to the technical field of production equipment for cables with braided shielding layers, and in particular to a device for removing burrs from the metal braided layer of cables. Background Technology

[0002] In the cable manufacturing industry, metal wire braiding is a commonly used shielding method for cables that need to meet specific electrical performance indicators. Its core function is to isolate external electromagnetic interference and ensure the stability and reliability of cable signal transmission. Due to the structural limitations of braiding equipment, there is an upper limit to the total amount of metal wire that the braiding machine spindle can carry, which cannot meet the continuous production needs of long-length cables. Therefore, during the production process, metal wires must be spliced ​​by changing spindles. In addition, metal wires are prone to breakage during the braiding process due to factors such as wire material and tension control. For these two production conditions of changing spindles and metal wire breakage, the industry's common approach is to braid the broken or spliced ​​metal wires into the braided shielding layer and then trim the excess wire ends to keep the surface of the braided shielding layer flat.

[0003] However, in actual production, it is difficult to achieve absolute flatness during wire trimming. Furthermore, cables inevitably bend during subsequent transport and processing, causing even trimmed wire ends to easily curl up again, forming sharp burrs. These burrs can puncture the cable's outer insulation layer during the subsequent sheath extrusion process due to extrusion pressure, exposing the internal conductive layer and leading to defective cable products. This not only increases raw material waste and production costs, reduces production efficiency, but also creates serious safety hazards, potentially causing electrical safety accidents such as leakage and short circuits during cable use.

[0004] To address the aforementioned burr problem, the industry currently lacks an efficient and universally applicable solution. Existing methods mainly fall into two categories: one is manual processing, which requires a significant investment of human resources, resulting in high labor intensity for workers and low processing efficiency, failing to meet the demands of large-scale, continuous cable production; the other is using fixed-specification cylindrical sleeves or wrapping non-woven fabric sleeves to cover the braided shielding layer. This method has very limited adaptability and cannot completely remove burrs. Furthermore, the metal shavings generated during the process are easily scattered into the production environment, causing environmental pollution and failing to meet the requirements of modern clean production.

[0005] It is evident that current methods for treating burrs in cable wire braided shielding layers have significant shortcomings. They cannot efficiently and stably solve the burr problem that occurs during production, and are difficult to adapt to the needs of large-scale, high-quality cable production. Therefore, developing a new burr treatment technology to address the deficiencies of existing technologies has become an urgent technical problem to be solved in the current cable production field. Summary of the Invention

[0006] The technical problem to be solved by this invention is that the current methods for dealing with burrs in the braided shielding layer of cables are all obviously insufficient, and cannot efficiently and stably solve the burr problem that occurs in the production process, making it difficult to adapt to the needs of large-scale and high-quality cable production.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a cable metal braid burr removal device, including a horizontal operating frame, the horizontal operating frame being composed of an L-shaped first mounting bracket and a second mounting bracket slidably mounted on the first mounting bracket, both the first and second mounting brackets having symmetrically opened arc-shaped cable guide grooves on their longitudinal sections, each arc-shaped cable guide groove having a detachable limiting frame installed at its upper opening, both the arc-shaped cable guide grooves and the detachable limiting frames having adjustable cable wheels inside, a bottom storage cover being fixedly mounted on the inner side of the first mounting bracket via a bottom bracket, a top flip cover being hinged to the upper opening of the bottom storage cover, and a detachable removal module being installed inside the bottom storage cover via a ring-shaped electrically controlled guide rail.

[0008] The first mounting bracket has several horizontally arranged bottom adjustment rails fixedly mounted on its upper surface. The second mounting bracket is slidably adjusted with the first mounting bracket by inserting a bottom slider into the upper opening of the bottom adjustment rail. The outer side of the bottom adjustment rail is threaded with a lateral locking bolt.

[0009] The detachable limiting frame is fixedly installed on the upper opening of the arc-shaped cable guide groove by bolts on both sides.

[0010] The position-adjustable cable wheel includes an electrically controlled support rod fixed to a first mounting bracket and a detachable limiting frame, an adjusting frame fixed to the extended end of the electrically controlled support rod, and an electrically driven wheel installed inside the adjusting frame.

[0011] The bottom storage cover and the top flip cover are symmetrically provided with arc-shaped cable-passing grooves on both sides to cooperate with the cable, and dust-proof brushes are provided on the inner wall of the arc-shaped cable-passing grooves.

[0012] The annular electrically controlled guide rail is fixedly installed inside the bottom storage cover by a lateral bracket. The annular electrically controlled guide rail includes an annular guide rail fixedly assembled with the lateral bracket, a sliding adjustment cover slidably installed at the opening of the annular guide rail, a guide slider and an adjustment electric drive wheel installed inside the sliding adjustment cover.

[0013] The outer side of the sliding adjustment cover has a limiting dust cover that bends toward the other side of the annular guide rail, and the outer side of the sliding adjustment cover has a lateral mounting groove corresponding to the guide slider position.

[0014] The detachable cleaning module includes an external mounting cover with mounting blocks on the side and an oblique friction strip fixed to the external mounting cover.

[0015] The bottom dust collection box is bolted to the side wall of the bottom support. A built-in dust pump and a filter frame located outside the built-in dust pump are fixedly mounted on the top surface of the bottom dust collection box. The bottom storage cover is fixedly connected to the inside of the bottom dust collection box through the bottom dust exhaust pipe. The top flip cover is connected to the air outlet of the built-in dust pump through the top exhaust pipe.

[0016] The bottom dust collection box has a telescopic opening on its side wall. A detachable quick-release box is slidably inserted into the telescopic opening. An arc-shaped notch is opened on one side of the upper end of the detachable quick-release box to match the bottom dust discharge pipe.

[0017] The beneficial effects of this invention are: (1) The cable metal braid burr removal device of the present invention achieves stable support and transportation of the cable through a horizontal operating frame. The position adjustable cable wheel can be adapted to cables of different specifications, ensuring that the cable does not deviate or get damaged during transportation. (2) The ring-shaped electric control rail drives the detachable cleaning module to move around the circumference of the cable, realizing all-round and efficient removal of burrs, which solves the problem of incomplete removal by existing processing methods; (3) The bottom storage cover, the top flip cover and the bottom dust collection box work together to achieve centralized collection of waste, avoid environmental pollution and meet the requirements of clean production; (4) Each component adopts a detachable structure, which facilitates installation, maintenance and replacement, and improves the practicality and service life of the device; (5) The overall structure is reasonably designed and highly adaptable, which can meet the needs of large-scale and continuous cable production, effectively solve the defects of existing technology, reduce production costs, improve production efficiency, and eliminate safety hazards.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The cable braided layer burr removal device shown includes a horizontal operating frame, which is composed of an L-shaped first mounting bracket 1 and a second mounting bracket 2. The second mounting bracket 2 is slidably connected to the bottom adjusting guide rail 11 on the upper surface of the first mounting bracket 1 via a bottom slider 12. The bottom adjusting guide rail 11 is locked and fixed to the bottom slider 12 on the outside by a lateral locking bolt 13. The longitudinal sections of the first mounting bracket 1 and the second mounting bracket 2 are symmetrically provided with arc-shaped cable guide grooves 3. A detachable limiting frame 4 is fixedly installed at the upper opening of the arc-shaped cable guide groove 3 by bolts 14 on both sides. An adjustable cable wheel 5 is fixed to the inner side of the arc-shaped cable guide groove 3 and the detachable limiting frame 4, respectively. One end of the electrically controlled support rod 15 of the adjustable cable wheel 5 is fixedly connected to the first mounting bracket 1 or the detachable limiting frame 4, and the extended end of the electrically controlled support rod 15 is fixedly connected to the adjusting frame 16. An electric drive wheel 17 is installed inside the adjusting frame 16. The inner side of the first mounting bracket 1 is fixedly connected to the bottom storage cover 7 via the bottom bracket 6. The top flip cover 8 is hinged to the upper opening of the bottom storage cover 7. Both the bottom storage cover 7 and the top flip cover 8 have symmetrical arc-shaped cable grooves 18 on both sides. The dust-proof brush 19 is fixed on the inner wall of the arc-shaped cable groove 18. The bottom storage cover 7 is fixedly connected to the annular electric control rail 9 via the side bracket 20. The annular guide rail 21 of the annular electric control rail 9 is fixedly assembled with the side bracket 20. The sliding adjustment cover 22 is slidably installed at the opening of the annular guide rail 21 via the guide slider 23 and the adjusting electric drive wheel 24. The limiting dust cover 25 is integrally formed on the outer side of the sliding adjustment cover 22. The side mounting slot 26 is opened on the outer side of the sliding adjustment cover 22 and corresponds to the position of the guide slider 23. The detachable cleaning module 10 is engaged with the side mounting slot 26 via the side mounting block 27 of the outer mounting cover 28. The inclined friction strip 29 is fixed on the outer mounting cover 28. The bottom dust collection box 30 is fixed to the side wall of the bottom bracket 6 by bolts. The built-in dust pump 31 and the filter frame 32 are both fixedly assembled on the inner top surface of the bottom dust collection box 30, and the filter frame 32 is sleeved on the outside of the built-in dust pump 31. The bottom storage cover 7 is connected to the inside of the bottom dust collection box 30 through the bottom dust discharge pipe 33, and the top flip cover 8 is connected to the air outlet of the built-in dust pump 31 through the top exhaust pipe 34. The side wall of the bottom dust collection box 30 is provided with a telescopic opening 35, and the detachable quick-release box 36 is slidably inserted into the telescopic opening 35. The arc-shaped notch 37 on the upper side of the detachable quick-release box 36 corresponds to and cooperates with the bottom dust discharge pipe 33.

[0029] The annular guide rail 21 is a fixed structure with an annular groove on one side. A sliding adjustment cover 22 fits onto the annular guide rail 21 on the same side as the opening of the annular groove. A guide slider 23 is fixed inside the sliding adjustment cover 22, and the guide slider 23 is inserted into the annular groove. An adjusting electric drive wheel 24 installed inside the guide slider 23 rotates, thereby controlling the rotation of the sliding adjustment cover 22 outside the annular guide rail 21. The limiting dust cover 25 can be understood as an extension of the annular guide rail 21, preventing dust from entering between the annular guide rail 21 and the sliding adjustment cover 22. A lateral mounting slot 26 is provided on the outside of the sliding adjustment cover 22 for insertion and fixing with a mounting block 27, facilitating the installation and removal of the external mounting cover 28 and its external detachable cleaning module 10.

[0030] Based on the above connection relationship, the working principle of this device is as follows: the adjustable cable wheel 5 achieves stable cable transportation; the annular electrically controlled guide rail 9 drives the detachable cleaning module 10 to move around the circumference of the cable, removing burrs from the surface of the cable braid layer in all directions; at the same time, the bottom dust collection box 30, in conjunction with the built-in dust pump 31, achieves centralized collection of waste, avoiding environmental pollution. All components work together to achieve efficient and stable burr removal, adapting to the production needs of cables of different specifications. Among them, the bottom adjustable guide rail 11 and the bottom slider 12 cooperate to adjust the bracket spacing to adapt to cables of different lengths; the electrically controlled support rod 15 adjusts the position of the electric drive wheel 17 to ensure smooth cable transportation; the adjustable electric drive wheel 24 drives the sliding adjustment cover 22 to slide along the annular guide rail 21 to achieve all-round cleaning by the brush; the built-in dust pump 31 sucks waste into the bottom dust collection box 30 through the bottom dust discharge pipe 33, the filter frame 32 filters the waste, and the detachable quick-release box 36 collects the waste, achieving clean production.

[0031] The working process is as follows: First, according to the specifications of the cable to be processed, adjust the position of the second mounting bracket 2 on the first mounting bracket 1. Slide the bottom slider 12 along the bottom adjusting guide rail 11 until it reaches the appropriate position, then tighten the side locking bolts 13 to secure it, ensuring that the distance between the two brackets matches the cable length. Next, remove the bolts 14 on both sides of the detachable limiting frame 4, place the cable inside the arc-shaped cable guide groove 3, and then fix the detachable limiting frame 4 to the upper opening of the arc-shaped cable guide groove 3 with bolts 14 to limit the cable movement. Then, activate the electric control support rod 15, which is fixedly connected to the first mounting bracket 1 and the detachable limiting frame 4, and adjust the position of the electric drive wheel 17 so that the electric drive wheel 17 is in close contact with the cable surface, ensuring that the cable does not... The device is tilted and does not wobble. Next, the top flip cover 8, hinged to the bottom storage cover 7, is opened. The detachable cleaning module 10 is then engaged with the lateral mounting slot 26 on the sliding adjustment cover 22 via the mounting clip 27 of the outer mounting cover 28, enabling quick installation of the detachable cleaning module 10. The top flip cover 8 is closed, allowing the cable to pass through the arc-shaped cable grooves 18 on both sides of the bottom storage cover 7 and the top flip cover 8, ensuring the cable is inside the detachable cleaning module 10. The dust-proof brush 19 on the inner wall of the arc-shaped cable groove 18 prevents external dust from entering the bottom storage cover 7. The device is started, and the electric drive wheel 17 connected to the adjustment frame 16 rotates, driving the cable forward at a uniform speed. The conveying speed can be flexibly adjusted according to the burr removal requirements. When the adjusting electric drive wheel 24 connected to the inner side of the sliding adjustment cover 22 is working, it drives the sliding adjustment cover 22 to slide at a constant speed along the annular guide rail 21, thereby driving the detachable cleaning module 10, which is engaged with the sliding adjustment cover 22, to move around the circumference of the cable. The limiting dust cover 25 on the outer side of the sliding adjustment cover 22 can prevent waste from entering the interior of the annular guide rail 21, thus avoiding affecting the sliding flexibility. The inclined friction strip 29 on the detachable cleaning module 10 performs all-round and efficient removal of burrs on the surface of the cable braid. The inclined structure can better fit the cable surface and improve the cleaning effect. At the same time, the built-in dust pump 31, which is fixed to the top surface of the bottom dust collection box 30, starts and generates negative pressure, which drives the metal waste generated by burr removal in the bottom collection cover 7 through the bottom. Dust pipe 33 draws dust into bottom dust collection box 30. Inside bottom dust collection box 30, filter frame 32, which works with built-in dust pump 31, filters waste debris to prevent it from entering the built-in dust pump 31 and causing damage. Filtered waste debris falls into detachable quick-release box 36, which is slidably connected to telescopic port 35. Purified air is discharged through top exhaust pipe 34, achieving centralized collection of waste debris. After the equipment has been working for a period of time, the equipment is turned off, and detachable quick-release box 36, which is slidably connected to telescopic port 35, is pulled out to clean the accumulated waste debris inside. After cleaning, detachable quick-release box 36 is inserted back into its original position through telescopic port 35. The arc-shaped notch 37 at the top of detachable quick-release box 36 fits tightly with bottom dust pipe 33 to prevent waste debris leakage.If the detachable cleaning module 10 needs to be replaced, the top flip cover 8 can be opened, and the detachable cleaning module 10 can be removed from the side mounting slot 26 through the mounting clip 27. After replacing it with a new detachable cleaning module 10, it can be reassembled. The operation is convenient. During equipment operation, the dust-proof brush 19 continuously plays a role in preventing dust and chips, and the limiting dust cover 25 protects the annular guide rail 21, ensuring long-term stable operation of the equipment and adapting to the needs of large-scale, continuous cable production.

[0032] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
