Description

Technical Field

[0001] The invention relates to the technical field of cable manufacturing, and in particular to an extrusion device for multiple cable insulation layers. Background Art

[0002] Cable is a general term for optical cables, electrical cables, etc. Cables have many uses, mainly used for controlling installation, connecting equipment, transmitting electricity, and other multiple functions. They are common and indispensable in daily life. Multi-core cables refer to cables with more than one insulated core.

At present, in the process of extruding the insulation layer of the multi-core cable, the insulation layer of the multi-core cable is usually directly extruded. In this operation mode, during the process of extruding the insulation layer of the multi-core cable, if the multi-core cable itself shakes or the multi-core cable is not aligned with the center position of the extruder when entering the extruder, the insulation layer extruded from the outside of the multi-core cable will be uneven, which seriously affects the production quality of the multi-core cable.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the present invention, a first electric telescopic rod and an arc plate are provided. When it is necessary to extrude an insulating layer on the cable, the cable passes through the inside of the fixed cylinder, and the arc plate abuts against the outside of the cable. At this time, the arc plate fixes and positions the passed cable, and the cable is fixed and positioned by the arc plate, so that the cable can maintain a stable state and pass through the center of the insulation layer extrusion head, thereby preventing the cable from shaking before the insulation layer is extruded. Therefore, when the insulation layer is extruded on the outside of the cable, the insulation layer coated on the outside of the cable can be more uniform, thereby preventing the insulation layer on the outside of the cable from being unevenly thickened due to the cable not being aligned with the insulation layer extrusion head when entering the insulation layer extrusion head, thereby affecting the production quality of the cable.

[0018] In the present invention, a first fixed block and a first rotating roller are provided, and the outer side of the cable abuts the first rotating roller. At this time, the pressure sensor monitors the outer side of the cable passing through the first rotating roller in real time and transmits the detection data to the background control system. There is a standard pressure value inside the background control system. The background control system compares the pressure value measured by the pressure sensor with the background standard pressure value. When the pressure value measured by the pressure sensor is less than the standard pressure value, it indicates that there is a depression on the outer side of the cable at this time. When the pressure value measured by the pressure sensor is greater than the standard pressure value, it indicates that there is a bulge on the outer side of the cable at this time. Since the multi-core cable is composed of multiple cables woven together, the detection result at this time can indicate that a single cable in the multi-core cable is not wound in place. At this time, the staff can detect the cable and the cable winding step, and can troubleshoot the equipment on the production line, which can effectively prevent the occurrence of product production defects and prevent the insulation layer from being unevenly coated when the insulation layer is extruded from the cable, thereby affecting the actual production quality of the cable.

[0019] In the present invention, by providing a third fixed block and a second rotating roller, when talcum powder is applied to the outer side of the cable, the sponge installed on the third fixed block abuts against the outer side of the cable, and then the fixed rod rotates around the cable. At this time, the sponge on the third fixed block can evenly apply the talcum powder on the outer side of the cable, and then the cable is extruded with an insulating layer. This operation method can improve the production quality of the finished cable.

[0020] When the outside of the cable needs to be wrapped with thin paper, the second rotating roller squeezes the outside of the cable, and the fixed rod rotates around the cable. At this time, the second rotating roller rolls on the outside of the cable, which can squeeze out the air inside the cable when the thin paper is wrapped on the outside of the cable, thereby preventing air from existing inside the cable when the cable is squeezed out of the insulation layer, affecting the tightness of the insulation layer covering the cable. This operation method can improve the production quality of the finished cable products.

[0021] In the present invention, a precooling box is provided. After the cable passes through the insulation layer extruder head, the cable coated with the insulation layer enters the interior of the precooling box from the inlet and outlet slots of the precooling box. At this time, the cold air in the precooling slot can quickly cool and shape the insulation layer on the outside of the cable. Then the cable passes through the precooling box and enters the cooling water tank. The precooling box cools and shapes the insulation layer on the outside of the cable, which can prevent the cable from directly entering the cooling water tank due to production defects such as insulation layer depression caused by water pressure and flow rate, thereby improving the production quality of the cable.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figure 1-8 , a multi-cable insulation layer extrusion device, comprising a mounting plate 1, a cooling water tank 2 is mounted on one side of the mounting plate 1, an insulation layer extrusion head 4 is mounted on the side of the mounting plate 1 close to the cooling water tank 2, a pre-cooling mechanism is provided between the cooling water tank 2 and the insulation layer extrusion head 4, a fixing cylinder 5 is mounted on the side of the mounting plate 1 close to the insulation layer extrusion head 4, a stabilizing mechanism is provided inside the fixing cylinder 5, a first detection mechanism is provided at one end of the fixing cylinder 5 close to the insulation layer extrusion head 4, and a second detection mechanism is provided at one end of the fixing cylinder 5 away from the insulation layer extrusion head 4. The stabilizing mechanism can stabilize and position the cable in the cable, improve the quality of the insulation layer coated on the cable, the first detection mechanism can detect the flatness of the outer side of the cable to ensure the production quality of the cable, and the second detection mechanism can pre-process the cable to improve the production quality of the cable.

[0033] As a technical optimization scheme of the present invention, the precooling mechanism includes a precooling box 3 and an opening 8. The mounting plate 1 is provided with a precooling box 3 between the cooling water trough 2 and the insulating layer extruder head 4. A precooling box 7 is provided inside the precooling box 3. The top and bottom of the inner wall of the precooling box 7 are evenly provided with a plurality of openings 8. The precooling box 3 is provided with an inlet and outlet groove 6 at one end close to the insulating layer extruder head 4 and one end close to the cooling water trough 2. After the cable passes through the insulating layer extruder head 4, the cable coated with the insulating layer enters the interior of the precooling box 3 from the inlet and outlet groove 6 of the precooling box 3. At this time, the cold air in the precooling groove 7 can quickly cool and shape the insulating layer on the outside of the cable. Then, the cable passes through the precooling box 3 and enters the cooling water trough 2. The precooling box 3 cools and shapes the insulating layer on the outside of the cable, thereby preventing the cable from directly entering the cooling water trough 2 and causing production defects such as insulating layer depression caused by the pressure and flow rate of the water flow, thereby increasing the production quality of the cable.

[0034] As a technical optimization solution of the present invention, the stabilizing mechanism includes a first electric telescopic rod 11 and an arc plate 27. The outer side of the fixed cylinder 5 is uniformly provided with a plurality of first slots 10 along the circumferential direction. The first electric telescopic rod 11 is installed inside the first slot 10. The telescopic end of the first electric telescopic rod 11 faces the inside of the fixed cylinder 5, and the telescopic end of the first electric telescopic rod 11 is located inside the fixed cylinder 5. The telescopic end of the first electric telescopic rod 11 is installed with an arc plate 27. The arc plate 27 abuts against the outer side of the cable. At this time, the arc plate 27 plays a role in fixing and positioning the passing cable. Moreover, the fixing and positioning of the cable by the arc plate 27 can make the cable pass through the center of the insulation layer extruder head 4 in a stable state, and prevent the cable from shaking before the insulation layer is extruded. Therefore, when the insulation layer is extruded outside the cable, the insulation layer coated on the outer side of the cable can be more uniform, and the thickness of the insulation layer on the outer side of the cable is not uniform due to the cable not being aligned with the insulation layer extruder head 4 when the cable enters the insulation layer extruder head 4, which affects the production quality of the cable.

[0035] As a technical optimization solution of the present invention, the first detection mechanism includes a first fixed block 9 and a first rotating roller 19. The first fixed block 9 is installed at one end of the arc plate 27 close to the insulating layer extruder head 4, and the first rotating roller 19 is movably installed at one end of the first fixed block 9 facing the center of the fixed cylinder 5. The first rotating roller 19 rolls on the outside of the cable, thereby completing the detection of the flatness of the outside of the cable.

[0036] As a technical optimization solution of the present invention, a second slot 15 is provided at one end of the first fixed block 9 facing the center of the fixed cylinder 5, a first movable block 18 is slidably installed inside the second slot 15, and a first rotating roller 19 is rotatably installed on a side of the first movable block 18 away from the bottom end of the inner wall of the second slot 15. The sliding of the first movable block 18 in the second slot 15 allows the first rotating roller 19 to have a movement stroke, thereby increasing the detection effect of the device.

[0037] As a technical optimization solution of the present invention, a pressure sensor 16 is installed at the bottom end of the inner wall of the second slot 15, and a spring telescopic rod 17 is installed on the side of the first movable block 18 away from the first rotating roller 19, and the telescopic end of the spring telescopic rod 17 is connected to the pressure sensor 16. The outer side of the cable abuts the first rotating roller 19. At this time, the pressure sensor 16 monitors the outer side of the cable passing through the first rotating roller 19 in real time and transmits the detection data to the background control system. There is a standard pressure value inside the background control system. The background control system compares the pressure value measured by the pressure sensor 16 with the background standard pressure value. When the pressure value measured by the pressure sensor 16 is less than the standard pressure value, it means that there is a depression on the outer side of the cable. When the pressure value measured by the pressure sensor 16 is greater than the standard pressure value, it means that there is a bulge on the outer side of the cable. Since the multi-core cable is composed of multiple cables woven together, the detection result at this time can indicate that a single cable in the multi-core cable is not wound in place. At this time, the staff can detect the cable and the cable winding steps, and can troubleshoot the equipment on the production line, which can effectively prevent the occurrence of product production defects and prevent the insulation layer from being unevenly coated when the cable is extruded. The actual production quality of the cable is affected.

[0038] As a technical optimization solution of the present invention, the second detection mechanism includes a fixed rod 13, a second fixed block 14 and a third fixed block 21. The fixed barrel 5 is movably mounted with multiple fixed rods 13 at one end away from the insulating layer extruder head 4, the fixed rod 13 is movably mounted with a third fixed block 21 at one end facing the center of the fixed barrel 5, and the fixed rod 13 is movably mounted with a second fixed block 14 at one end away from the center of the fixed barrel 5. Auxiliary detection of the cable can be completed by the third fixed block 21 and the second fixed block 14 installed on the fixed rod 13.

[0039] As a technical optimization solution of the present invention, an annular guide rail 12 is installed at one end of the fixed cylinder 5 away from the insulating layer extruder head 4, and an electric slider 20 is connected to the side of the fixed rod 13 close to the annular guide rail 12, and the electric slider 20 is slidably installed inside the annular guide rail 12. By sliding the electric slider 20 in the annular guide rail 12, the fixed rod 13 can make a circular motion outside the annular guide rail 12.

[0040] As a technical optimization solution of the present invention, a rotating motor 28 is movably embedded and installed on one side of the fixed rod 13 close to the annular guide rail 12, and the installation end of the rotating motor 28 is connected to the electric slider 20. The second electric telescopic rod 23 is embedded and installed at both ends of the fixed rod 13, and the telescopic end of the second electric telescopic rod 23 is away from the fixed rod 13. The second fixed block 14 and the third fixed block 21 are connected to the telescopic end of the second electric telescopic rod 23 on one side close to the fixed rod 13. The rotating motor 28 can drive the fixed rod 13 to rotate, so that the third fixed block 21 and the second fixed block 14 can complete the switching of the use function, and the second electric telescopic rod 23 can drive the third fixed block 21 and the second fixed block 14 to extend, so that they can be better used in conjunction with the cable, increasing the convenience of use of the device.

[0041] As a technical optimization scheme of the present invention, a sponge is installed on the side of the third fixed block 21 away from the fixed rod 13, a third slot 24 is provided on the side of the second fixed block 14 away from the fixed rod 13, a second movable block 26 is slidably installed inside the third slot 24, a second rotating roller 22 is rotatably installed on the side of the second movable block 26 away from the second fixed block 14, and a plurality of buffer springs 25 are evenly connected between the bottom end of the second movable block 26 and the bottom end of the inner wall of the third slot 24. When talcum powder is applied to the outside of the cable, the sponge installed on the third fixed block 21 abuts against the outside of the cable, and then slides in the annular guide rail 12 through the electric slider 20, so that the fixed rod 13 rotates around the cable. At this time, under the movement of the fixed rod 13, the sponge on the third fixed block 21 can evenly apply the talcum powder on the outside of the cable, and then the cable is extruded with an insulating layer. This operation method can improve the production quality of the finished cable;

[0042] When the outside of the cable needs to be wrapped with thin paper, the second rotating roller 22 squeezes the outside of the cable, and the electric slider 20 slides in the annular guide rail 12, so that the fixed rod 13 rotates around the cable. At this time, under the movement of the fixed rod 13, the second rotating roller 22 rolls on the outside of the cable, which can squeeze out the air inside the cable when the thin paper is wrapped on the outside of the cable, thereby preventing air from existing inside the cable when the cable is squeezed out of the insulating layer, which affects the tightness of the insulating layer covering the cable. This operation method can improve the production quality of the finished cable.

[0043] When the present invention is in use, a background control system is provided on the device, and the background control system can control all the electric drive mechanisms on the device. The cooling water trough 2 and the insulating layer extruder head 4 used in the device are existing mature technologies, so their working principles and usage methods are not elaborated too much. When it is necessary to extrude the insulating layer of the cable, the cable is transmitted from the end of the fixed cylinder 5 away from the cooling water trough 2, and then the cable passes through the inside of the fixed cylinder 5, and then passes through the insulating layer extruder head 4. When the cable passes through the insulating layer extruder head 4, the insulating layer is successfully attached to the outside, and then the cable passes through the pre-cooling box 3 and passes through the inlet and outlet grooves 6 on the pre-cooling box 3, and then the cable enters the cooling water trough 2 for cooling. After the cable passes through the cooling water trough 2, there is a pulling device at the end to pull the cable, so as to provide power support for the cable passing through multiple mechanisms on the device. The pulling device is an existing mature technology, so it is not elaborated too much. The opening 8 is externally connected to the cooling fan through a conduit.

[0044] When the cable passes through the fixed tube 5, the first electric telescopic rod 11 drives the arc plate 27 to extend, so that the arc plate 27 abuts against the outside of the cable. At this time, the arc plate 27 fixes and positions the passed cable, and the arc plate 27 fixes and positions the cable, so that the cable can maintain a stable state and pass through the center of the insulation layer extruder head 4, preventing the cable from shaking before the insulation layer is extruded. When the insulation layer is extruded on the outside of the cable, the insulation layer wrapped on the outside of the cable can be more uniform, preventing the cable from entering The insulation layer extruder head 4 is not aligned with the insulation layer extruder head 4, which causes the thickness of the insulation layer on the outside of the cable to be inconsistent, thereby affecting the production quality of the cable.

[0045] When the cable passes through the fixed tube 5, the outer side of the cable abuts the first rotating roller 19, and the first movable block 18 squeezes the spring telescopic rod 17, and the spring telescopic rod 17 squeezes the pressure sensor 16. At this time, the pressure sensor 16 monitors the outer side of the cable passing through the first rotating roller 19 in real time and transmits the detection data to the background control system. There is a standard pressure value inside the background control system. The background control system compares the pressure value measured by the pressure sensor 16 with the background standard pressure value. When the pressure value measured by the pressure sensor 16 is less than the standard pressure value, it means that there is a depression on the outer side of the cable. When the pressure value measured by the pressure sensor 16 is greater than the standard pressure value, it means that there is a protrusion on the outer side of the cable. Since the multi-core cable is woven by combining multiple cables, the detection result at this time can indicate that a single cable in the multi-core cable is not wound in place. At this time, the staff can detect the cable and the cable winding step, and can troubleshoot the device on the production line, which can effectively prevent the occurrence of product production defects and prevent the cable from being unevenly coated with the insulation layer when the insulation layer is extruded, thereby affecting the actual production quality of the cable.

[0046] After the cable passes through the insulation layer extruder head 4, the cable coated with the insulation layer enters the interior of the pre-cooling box 3 from the inlet and outlet groove 6 of the pre-cooling box 3. At this time, the cold air in the pre-cooling groove 7 can quickly cool and shape the insulation layer on the outside of the cable. Then the cable passes through the pre-cooling box 3 and enters the cooling water tank 2. The cooling and shaping of the insulation layer on the outside of the cable by the pre-cooling box 3 can prevent the cable from directly entering the cooling water tank 2 due to production defects such as insulation layer depression caused by water pressure and flow rate, thereby increasing the production quality of the cable.

[0047] Before extruding the insulating layer of a multi-core cable, talcum powder or thin paper will be applied to the outside of the cable. When talcum powder is applied to the outside of the cable, the current operation method of applying talcum powder to the cable is that the cable passes through a pile of talcum powder, so that the outside of the cable is coated with talcum powder. Through this operation method, since the multi-core cable is made of multiple cables wound and woven, most of the talcum powder has the problem of uneven application. At this time, the third fixed block 21 is driven by the second electric telescopic rod 23 to extend toward the fixed cylinder 5, so that the sponge installed on the third fixed block 21 abuts against the outside of the cable, and then the electric slider 20 slides in the annular guide rail 12, so that the fixed rod 13 rotates around the cable. At this time, under the movement of the fixed rod 13, the sponge on the third fixed block 21 can evenly apply the talcum powder on the outside of the cable, and then the cable is extruded with an insulating layer. This operation method can improve the production quality of the finished cable.

[0048] When the outside of the cable needs to be wrapped with thin paper, the method of wrapping the thin paper on the outside of the cable is to use an existing winding machine, so it will not be elaborated on in detail. At this time, the fixed rod 13 is driven to rotate by the rotating motor 28, so that the second fixed block 14 is rotated to a position facing the center of the fixed cylinder 5, and then the second fixed block 14 is driven to extend by the second electric telescopic rod 23, so that the second rotating roller 22 squeezes the outside of the cable, and the electric slider 20 slides in the annular guide rail 12, so that the fixed rod 13 rotates around the cable. At this time, under the movement of the fixed rod 13, the second rotating roller 22 rolls on the outside of the cable, which can squeeze out the air inside the cable when the thin paper is wrapped on the outside of the cable, so as to prevent the existence of air inside the cable when the cable is squeezed out of the insulating layer, which affects the tightness of the insulating layer covering the cable. This operation method can improve the production quality of the finished cable.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
