Description

Technical Field

[0001] This invention relates to the field of cable polishing technology, and more specifically, to a cable insulation layer polishing device and a polishing method thereof. Background Technology

[0002] Cable insulation refers to the critical material layer specifically wrapped around the outside of the cable conductor. Its main function is to provide both electrical insulation and mechanical protection. This material can effectively prevent current from leaking out of the conductor, thereby ensuring that the cable will not experience potential safety accidents such as short circuits or leakage during normal operation. In addition, the insulation layer also has a certain mechanical strength, which can withstand various external mechanical forces, such as tension, compression, and bending, thereby protecting the internal conductor from physical damage. It can be said that cable insulation plays a vital and fundamental role in ensuring the overall performance and operational safety of the cable, and is an indispensable and important component of the cable structure.

[0003] According to patent document CN116117661B, a cable insulation layer grinding device and method are disclosed. The cable insulation layer grinding device includes a cutting tool capable of rotating around the cable's axis, moving along a first direction and a second direction, and simultaneously cutting the cable's insulation layer. It also includes a detection component that, when detecting contact between the cutting tool and the cable's conductor core, stops the cutting tool from rotating along the cable's axis and from cutting the cable's insulation layer along the second direction, preventing damage to the conductor core and protecting the cable's service life. The cable insulation layer grinding method, after detecting contact between the cutting tool and the conductor core, moves the cutting tool a fourth preset distance in the opposite direction along the second direction, further protecting the conductor core while fully cutting the cable's insulation layer, increasing work efficiency and protecting the cable's service life.

[0004] When performing cable insulation layer polishing, sandpaper is generally used for manual polishing, or fine polishing is carried out by hand. Alternatively, a grinding wheel machine may be used for semi-automatic polishing. Regardless of whether manual polishing with sandpaper, hand polishing, or semi-automatic polishing with a grinding wheel machine is used, all these methods inevitably require a large amount of manpower. Moreover, due to significant differences in polishing skills and experience among different operators, it may be difficult to achieve uniformity in the polishing process of the outer surface of the cable insulation layer. In addition, a large amount of dust is generated during polishing. This dust not only harms the health of the operators, such as causing respiratory diseases, but also pollutes the working environment and affects the normal operation and service life of the equipment. Summary of the Invention

[0015] In addition, the present invention also relates to a polishing method for a cable insulation layer polishing device, comprising the following steps: Step 1: Place the stripped cable to be polished inside the two arc-shaped clamping plates, ensuring the cable is in the right position for subsequent clamping operations; Step 2: Start the lifting electric push rod, pull the triangular stop block downwards, so that the two triangular expansion plates slide inwards under the action of spring force, driving the two arc-shaped clamping plates to move closer to the middle until the cable is clamped.

The gears rotate with the columnar rotating rods and mesh with the outer wall of the C-shaped external gear disc to drive the C-shaped external gear disc to make circular motion on the circular slide plate. When the C-shaped external gear disc rotates, it drives the guide plate to rotate synchronously through the columnar connecting rod, so that the grinding belt makes circular motion around the cable axis. Step Six: Start the second motor. The second motor drives the grinding belt to rotate through the drive shaft and the third track, driving the grinding belt to perform circumferential grinding on the cable surface. As the cable continues to move forward, multiple grinding seats perform continuous and uniform grinding operations on the cable insulation layer to ensure that the insulation layer surface is smooth and flat, without defects or protrusions. Step 7: During the polishing process, the dust collection box, together with the dust extraction pipe and dust collection pipeline, works continuously to suck up and collect the dust and debris generated during the polishing process into the dust storage pipe.

Throughout the grinding process, the coordinated operation of various components not only ensures grinding quality and improves grinding efficiency, making the insulation layer surface smooth, flat, and free of defects and protrusions, but also effectively solves the problem of dust and debris flying during the grinding process. The cooperation between the dust collection box, dust extraction pipe, and dust collection pipeline can promptly suck the generated dust and debris into the dust collection pipe, avoiding the impact of dust on the working environment and the health of operators, achieving the dual goals of environmental protection and high efficiency, and greatly improving the overall efficiency of cable insulation layer grinding work.

During the forward movement of the cable, multiple grinding components 2252 on the front side of the multiple grinding control components 2251 are first activated. The electric push rods 22524 of the multiple grinding components 2252 are activated to push multiple L-shaped moving plates 22526 to expand and contract, so that the grinding strips 22535 of the multiple grinding components 2252 are attached to the surface of the cable insulation layer. Then, the motor 216 is activated. The motor 216 activates the transmission columnar transmission rod 224 to rotate. When the columnar transmission rod 224 rotates, it drives the third transmission disc 22510 to rotate. The third transmission disc 22510 is connected to the second... Track 22519 drives the second transmission disc 22518 to rotate synchronously, which in turn causes the top columnar rotating rod 22514 to drive the transmission disc 22516 to rotate. The transmission disc 22516 drives multiple sets of columnar rotating rods 22514 to rotate synchronously via track 22517. Gear 22515 rotates with the columnar rotating rods 22514 and meshes with the outer wall of the C-shaped external gear disc 225101, driving the C-shaped external gear disc 225101 to perform circular motion on the circular slide plate 22512. When the C-shaped external gear disc 225101 rotates, it drives the guide plate via the columnar connecting rod 22522. 22521 rotates synchronously, causing the grinding belt 22535 to move in a circular motion around the cable axis. At this time, the second motor 22532 starts, driving the grinding belt transmission roller 22529 to rotate through the transmission shaft 22533 and the third track 22534, thereby driving the grinding belt 22535 to perform circumferential grinding on the cable surface. As the cable continues to move forward, multiple grinding seats 225 perform continuous and uniform grinding operations on the cable insulation layer, ensuring that the insulation layer surface is smooth and flat, without defects or protrusions. During this process, the dust collection box 217 works in conjunction with the dust extraction pipe 2110 and the dust collection pipe. The grinding channel 219 operates continuously, promptly sucking in and collecting the dust and debris generated during the grinding process into the dust collection pipe 218. This effectively prevents dust from affecting the working environment and the health of operators, while also ensuring the cleanliness and normal operation of the grinding equipment. Multiple grinding control components 2251 work in concert, greatly improving the precision and efficiency of grinding. The grinding equipment has a compact and reasonable structural design, with stable connections between components, stable and reliable operation, reducing the probability of failure and lowering maintenance costs, thus providing a strong guarantee for high-quality grinding of cable insulation layers.

[0023] In addition, the present invention also relates to a polishing method for a cable insulation layer polishing device, comprising the following steps: Step 1: Place the stripped cable to be polished inside the two arc-shaped clamping plates 147, ensuring that the cable is in the right position for subsequent clamping operations; Step 2: Start the lifting electric push rod 144, pull the triangular stop block 145 downward, so that the two triangular expansion plates 146 slide inward under the elastic force of the spring 143, driving the two arc-shaped clamping plates 147 to move closer to the middle until the cable is clamped. Step 3: Activate the multiple grinding components 2252 on the front side of the multiple grinding control components 2251, so that the electric push rods 22524 of the multiple grinding components 2252 push the multiple L-shaped moving plates 22526 to move in and out, so that the grinding belts 22535 of the multiple grinding components 2252 adhere to the surface of the cable insulation layer. Step 4: Start motor 216. Motor 216 drives columnar transmission rod 224 to rotate. Columnar transmission rod 224 drives third transmission disk 22510 to rotate. Third transmission disk 22510 drives second transmission disk 22518 to rotate synchronously through second track 22519, so that top columnar transmission rod 22514 drives transmission disk 22516 to rotate. Step 5: The transmission disc 22516 drives multiple sets of columnar rotating rods 22514 to rotate synchronously through the track 22517. The gear 22515 rotates with the columnar rotating rods 22514 and meshes with the outer wall of the C-shaped external gear disc 225101 to drive the C-shaped external gear disc 225101 to make circular motion on the circular slide plate 22512. When the C-shaped external gear disc 225101 rotates, it drives the guide plate 22521 to rotate synchronously through the columnar connecting rod 22522, so that the grinding belt 22535 makes circular motion around the cable axis. Step Six: Start the second motor 22532. The second motor 22532 drives the grinding belt transmission roller 22529 to rotate through the transmission shaft 22533 and the third track 22534, driving the grinding belt 22535 to perform circumferential grinding on the cable surface. As the cable continues to move forward, multiple grinding seats 225 perform continuous and uniform grinding operations on the cable insulation layer to ensure that the surface of the insulation layer is smooth and flat, without defects or protrusions. Step 7: During the polishing process, the dust collection box 217 works continuously with the dust extraction pipe 2110 and the dust collection pipe 219 to promptly suck in and collect the dust and debris generated during the polishing process into the dust storage pipe 218.

[0024] Working principle of this invention: When it is necessary to grind the cable insulation layer, the stripped cable is first placed inside the two arc-shaped clamping plates 147. Then, the lifting electric push rod 144 is activated to pull the triangular stop block 145 downward. At this time, the two triangular expansion plates 146 slide inward under the elastic force of the spring 143, thereby driving the two arc-shaped clamping plates 147 to move closer to the middle until the cable is tightly clamped. Multiple pulleys 148 play an auxiliary sliding role during the movement of the cable. During the forward movement of the cable, multiple grinding control components are first activated. Multiple grinding components 2252 on the front side of 2251, with electric push rods 22524 activating to drive multiple L-shaped moving plates 22526 to expand and contract, causing the grinding belts 22535 of the multiple grinding components 2252 to adhere to the surface of the cable insulation layer. Then, motor 216 is activated, and motor 216 starts the transmission columnar rotating rod 224 to rotate. The rotation of the columnar rotating rod 224 drives the third transmission disc 22510 to rotate. The third transmission disc 22510, through the second track 22519, drives the second transmission disc 22518 to rotate synchronously, thereby causing the top columnar... The rotating rod 22514 drives the transmission disc 22516 to rotate. The transmission disc 22516 drives multiple sets of columnar rotating rods 22514 to rotate synchronously via the track 22517. The gear 22515 rotates with the columnar rotating rods 22514 and meshes with the outer wall of the C-shaped external gear disc 225101, driving the C-shaped external gear disc 225101 to perform circular motion on the circular slide plate 22512. When the C-shaped external gear disc 225101 rotates, it drives the guide plate 22521 to rotate synchronously via the columnar connecting rod 22522, causing the grinding belt 22535 to perform circular motion around the cable axis. At this time, the second electric... When the machine 22532 is started, the transmission shaft 22533 and the third track 22534 drive the grinding belt transmission roller 22529 to rotate, thereby driving the grinding belt 22535 to perform circumferential grinding on the cable surface. As the cable continues to move forward, multiple grinding seats 225 perform continuous and uniform grinding operations on the cable insulation layer to ensure that the surface of the insulation layer is smooth and flat, without defects or protrusions. During this process, the dust collection box 217 works continuously with the dust extraction pipe 2110 and the dust collection pipe 219 to suck up the dust and debris generated during the grinding process and collect them into the dust storage pipe 218 in a timely manner.
