Description

Technical Field

[0001] This utility model relates to the field of materials processing technology, and in particular to a calendering device for data cable production. Background Technology

[0002] A calendering device is a specialized piece of equipment that uses mechanical pressure to extrude and stretch metal or polymer materials, transforming them from their original form into a specific shape with uniform thickness and a smooth surface. The core function of the device is to solve the problems of material thickness control and shape shaping. It is applied in the processing field and is one of the key pieces of equipment in material forming and processing.

[0003] In the data cable production process, the rolling mill is a key piece of equipment used to roll the core metal conductor material of the data cable. Its core function is to extrude and extend the metal wire through mechanical pressure, processing it into a specific shape that meets the specifications of the data cable. It is one of the core links to ensure the conductivity, structural stability and appearance accuracy of the data cable. The rolling mill extrudes the original round metal wire through rollers and extends it into a flat conductor with uniform thickness, while ensuring that the cross-sectional area of ​​the conductor is consistent, avoiding local overheating during current transmission, and eliminating tiny gaps inside the metal conductor to improve the conductivity of the conductor. However, the metal conductor sticks to the surface of the rollers during high-temperature rolling. Traditional structures rely on scrapers for cleaning, but the gap between the scraper and the rollers is difficult to control. If the gap is too large, the cleaning is not thorough, and if the gap is too small, the roller surface will be scratched. The sticky material causes indentations in the subsequent rolled material, affecting the appearance and performance of the data cable. Utility Model Content

The relative movement of the upper and lower pressure rollers 303 and 304 completes the calendering process. The grooves 305 are engraved on the surfaces of the upper and lower pressure rollers 303 and 304, and are fine grooves. After liquid seeps in, it remains in the grooves, forming a protective film on the surface of the rollers. The oil tank 306 contains silicone oil, which is a good mold release agent. After the oil drip nozzle 307 is opened... The silicone oil can slowly seep out and replenish the groove 305. The silicone oil flows from the drip nozzle 307 through the brush 308 and is applied to the upper pressure roller 303 by the brush 308. Some of the silicone oil in the upper pressure roller 303 drips down and is captured by the lower pressure roller 304, completing the replenishment. The connecting column 3091 is located on the output side of the calendering mechanism 3. The sensor 3092 is used to monitor the thickness of the finished product. If it exceeds the error range, it will automatically provide feedback and adjustment. The groove structure reduces the contact area between the wire and the roller surface.

An electrical box 403 is fixedly connected to the rear of the heating box 401 to provide electrical energy. Multiple heating plates 404 are fixedly connected to the inner wall of the heating box 401. When the heating plates 404 are energized, they dissipate electricity. It can be converted into heat energy to heat the internal air. The top of the heating box 401 is provided with an air outlet 405, which is directly opposite the bottom of the guide roller 4071. It is used to heat the wire passing through the surface of the guide roller 4071. Multiple louvers 406 are fixedly connected to the inner wall of the air outlet 405. The louvers 406 make the air blowing more uniform, that is, the heating is uniform. The outer wall of the support frame 2 is provided with a guide component 407, which is used to guide.

[0037] The guide assembly 407 includes a guide roller 4071, the outer wall of which is rotatably connected to the outer wall of the support frame 2.

[0039] Reference Figure 1 , Figure 2 and Figure 3 The unwinding mechanism 5 includes an unwinding roller 501. The outer wall of the unwinding roller 501 is rotatably connected to the outer wall of the support frame 2. The unwinding roller 501 is used to store the wire coil before calendering and outputs it by rotation. The outer wall of the unwinding roller 501 is fixedly connected to a limiting plate 502. The limiting plate 502 divides the unwinding roller 501 into two parts, which means that both ends can work at the same time and double the speed. The limiting plate 502 is used to block both ends and prevent deviation.

[0040] The winding mechanism 6 includes a third motor 601, the rear side of which is fixedly connected to the front side of the support frame 2. The third motor 601 provides rotational power to the take-up roller 602. The output end of the third motor 601 is fixedly connected to the take-up roller 602, which is an active roller used to wind up the calendered wire.

[0041] The outer wall of the support frame 2 is rotatably connected to a guide roller 7. The guide roller 7 has the same function as the guide roller 4071, which is to guide the wire. When rotating, it tightens the wire and provides tension to facilitate the collection after calendering. The outer wall of the guide roller 7 is fixedly connected to a limit ring 8. The limit ring 8 is used to separate the wires on both sides to prevent them from shifting and overlapping, which would cause the wires to become tangled. The outer wall of the support frame 2 is fixedly connected to multiple fixing plates 9. The fixing plates 9 are used to support the motor and facilitate the installation of the motor. The top of the bottom plate 1 is provided with a collection groove 10. The collection groove 10 is used to collect the dripping silicone oil at the bottom to reduce the pollution caused by splashing.

[0042] Specifically, the unwinding roller 501 is used to store the wire coil before calendering. Through rotation output, the limiting plate 502 divides the unwinding roller 501 into two parts, which means that both ends can work simultaneously, doubling the speed. The limiting plate 502 is used to block both ends to prevent deviation. The third motor 601 provides rotational power to the take-up roller 602. The take-up roller 602 is an active roller used to take up the calendered wire. The second guide roller 7 has the same function as the first guide roller 4071, both serving as guides. When rotating, it tightens the wire and provides tension to facilitate collection after calendering. The second limiting ring 8 is used to separate the wire on both sides to avoid offset and overlap, which would cause tangled wire. The fixing plate 9 is used to support the motor and facilitate motor installation. The collection trough 10 is used to collect the dripping silicone oil at the bottom to reduce pollution caused by splashing.

[0043] Working principle: When the device is working, the upper pressure roller 303 and the lower pressure roller 304 move relative to each other to complete the calendering of the wire. The groove 305 is a fine groove engraved on the surface of the upper pressure roller 303 and the lower pressure roller 304. After the silicone oil seeps in, it remains in the groove. When the wire passes through, it is coated with silicone oil. Silicone oil is a good release agent. At the same time, the oil tank 306 contains silicone oil. When the oil dripping nozzle 307 is working, it can slowly seep out silicone oil to replenish the groove 305. The silicone oil flows from the oil dripping nozzle 307 through the brush 308 and is applied to the upper pressure roller 304 by the brush 308. On the 03, some of the silicone oil dripping from the upper pressure roller 303 is captured by the lower pressure roller 304, completing the replenishment. The sensor 3092 monitors the thickness of the finished product after calendering. If it exceeds the error range, it automatically provides feedback and adjustment. The first motor 301 is responsible for providing power for the counterclockwise rotation of the upper pressure roller 303, while the second motor 302 is responsible for providing power for the clockwise rotation of the lower pressure roller 304. The groove structure reduces the contact area between the wire and the roller surface, reducing the possibility of sticking to the roller. Moreover, the silicone oil is evenly adhered to the material surface, further preventing sticking to the roller.

[0044] Furthermore, before the wire is rolled, the unrolled wire needs to be heated in the heating box 401. The fan 402 is started to provide airflow, and the electrical box 403 provides power to the heating plate 404. After the heating plate 404 is powered on, it converts electrical energy into heat energy to heat the air inside the heating box 401. The air outlet 405 is directly opposite the bottom of the guide roller 4071 to heat the wire passing over the surface of the guide roller 4071. The louvered plate 406 makes the airflow more uniform, that is, the heating is uniform. The guide roller 4071 is used to tighten the wire when rotating to provide tension. The limiting ring 4072 is used to prevent the wire from deviating. The wire is preheated to allow it to be rolled better and to form a protective layer with the silicone oil to prevent oxidation.
