Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and in particular to a coating device and a use method for processing ultra-light fluoroplastic extrusion cables. Background Art

[0002] The ultra-light fluoroplastic extrusion cable is a kind of cable, and its insulation adopts the insulation form of a polytetrafluoroethylene coating. The polytetrafluoroethylene surface coating can effectively homogenize the electric field and reduce the influence of mechanical noise on the product. The existing coating method is to immerse the cable to be processed in a polytetrafluoroethylene solution, and then complete the coating process after sintering and shaping in a sintering furnace. Since the solution has good fluidity and the insulation surface of the ultra-light fluoroplastic extrusion cable is smooth, the existing production line, such as the pay-off device, coating device, sintering device, and take-up device, etc., are all horizontally placed and arranged in a line. The horizontal tank used in traditional coating processing not only makes the production line too long and requires more factory building area, but also after the cable leaves the solution inside the horizontal tank, the solution hanging on the insulation surface shifts to one side of the cable under the influence of its own gravity and the liquid surface tension, resulting in uneven distribution of the coating on the insulation surface and the coating thickness not meeting the standard.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, the container is arranged below the sintering furnace, and three guiding mechanisms are provided, so that the cable moves upward into the sintering furnace after entering the container deeply, realizing vertical soaking and vertical sintering. Firstly, it avoids the problems of too long tank body in the prior art and the sintering furnace being arranged on one side of the coating tank body, resulting in too large occupied space.

Further, the buffer assembly can use double-headed studs, connecting screw holes and nuts to quickly assemble the platform and the mounting plate, with convenient installation; 3. A guiding wheel, a swing rod and a locking bolt are provided. After loosening the locking bolt, the swing angle of the swing rod can be adjusted, thereby realizing the adjustment of the spacing of the first gap, facilitating the adaptation of cables with different outer diameters. After tightening the locking bolt, the stability of the swing rod and the guiding wheel is ensured; 4. A first lifting mechanism and a second lifting mechanism are provided. By moving the lifting cylinder body in the second sleeve, the vertical height of the container is adjusted, and by moving the lifting rod body in the first sleeve, the cable inlet position is synchronously moved, ensuring the full utilization of the vertical space in the factory area and ensuring that the cable inlet position corresponds to the upper opening position of the container, ensuring that the cable can enter the container. On this basis, an extension rod is provided at the top of the lifting cylinder body to ensure that the cable outlet position is always above the container, ensuring the stable installation of each guiding mechanism; 5. A solution replenishing mechanism is provided. When the content of the coating solution in the container is lower than the preset value, the water pump will extract the coating solution from the liquid storage tank and send it into the container through the liquid extraction pipe, water pump, liquid supply pipe, solution replenishing channel and liquid discharge pipe, ensuring a stable and continuous coating effect. The solution replenishing channel is arranged inside the lifting cylinder body and the second sleeve, eliminating the need for additional piping and avoiding the drawbacks of external piping being prone to damage and occupying extra space.

It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. In addition, it should be noted that for the convenience of description, only the parts related to the invention are shown in the drawings.

[0019] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and embodiments.

[0020] Embodiment 1

[0021] Please refer to Figures 1 to 6 , this embodiment provides a coating device for processing ultra - light fluoroplastic extruded cables, which is arranged below the sintering furnace 75 and includes: The coating mechanism 2 includes a container 21 arranged below the sintering furnace 75. The container 21 is internally provided with a coating solution. An outlet position is arranged above one side of the container 21 along the first direction, and an inlet position is arranged on the side of the container 21 away from the outlet position along the first direction; Three guiding mechanisms 1 are respectively arranged at the inner bottom surface of the container 21, the wire outlet position and the wire inlet position, and each includes a first gap for clamping the cable. The extending direction of the first gap corresponding to the guiding mechanism 1 at the wire inlet position and the inner bottom surface of the container 21 is parallel to the first direction, and the extending direction of the first gap corresponding to the guiding mechanism 1 at the wire outlet position is parallel to the second direction; On both sides of the first gap, there are respectively a first platform 12 and a second platform 13. On the mutually approaching sides of the first platform 12 and the second platform 13, there are respectively a first guide wheel group and a second guide wheel group. Both the first guide wheel group and the second guide wheel group include a number of guide wheels 113 arranged along the extending direction of the first gap. The number of guide wheels 113 in the first guide wheel group and the number of guide wheels 113 in the second guide wheel group are staggeredly arranged. A first gap is formed between the two groups of guide wheels 113. The extending direction of the axis of each guide wheel 113 is the third direction. The first direction, the second direction and the third direction are perpendicular to each other; wherein, the first direction is Figure 1 the left - right direction in Figure 1 , the second direction is Figure 1 the up - down direction in , and the third direction is the front - back direction in Figure 1 . Figure 2 In addition, a connecting beam 11 is arranged between the first platform 12 and the second platform 13 to ensure the relative positions between them are stable and ensure the stability of the guiding mechanism 1 after assembly; Figure 3 On both the first platform 12 and the second platform 13, a number of buffer components are installed. Each buffer component is used to reduce the vibration of the cable along the fourth direction. The fourth direction, the third direction and the extending direction of the first gap are perpendicular to each other; wherein, the fourth direction will change with the installation position of the guiding mechanism 1, and it is parallel to the normal direction of the first platform 12 and the second platform 13; Further, due to the buffer components, the cable is pressed by the staggeredly arranged guide wheels 113. During the cable movement process, part of the vibration energy of the cable is absorbed, the vibration during the cable transportation is reduced, and the problem that the solution on the insulating surface of the cable flows due to vibration and finally causes uneven distribution of the coating on the insulating surface is avoided.

[0022] In some embodiments, the buffer assembly includes a plurality of limiting columns 17 arranged and distributed along the extension direction of the first gap at the ends close to each other of the first platform 12 and the second platform 13, the limiting column 17 on the first platform 12 is movably sleeved with a first mounting plate 14 at the end away from the first platform 12, and the limiting column 17 on the second platform 13 is movably sleeved with a second mounting plate 15 at the end away from the second platform 13, and a plurality of compression springs 18 are evenly arranged between the first mounting plate 14 and the first platform 12 and between the second mounting plate 15 and the second platform 13, and the moving direction of the first mounting plate 14 and the second mounting plate 15, the axial direction of the compression spring 18, and the axial extension direction of the limiting column 17 are all fourth directions; Each guide wheel 113 of the first guide wheel group is installed on the first mounting plate 14, and each guide wheel 113 of the second guide wheel group is installed on the second mounting plate 15; like Figure 1 , Figure 2 and Figure 3 As shown, when the cable vibrates, the vibration energy of the cable is absorbed by the compression springs 18 on both sides to alleviate or completely prevent the vibration of the cable. In addition, the compression spring 18 can be mounted on the outside of the limiting column 17 to ensure the stability of the compression spring 18 during contraction or extension. Furthermore, the staggered guide wheel pressures 113 and the evenly arranged compression springs 18 can greatly restrict the cable, ensuring that the first mounting plate 14 and the guide wheel 113 of the first guide wheel group can stably and synchronously buffer and reduce shock. Similarly, it also ensures that the second mounting plate 15 and the guide wheel 113 of the second guide wheel group can stably and synchronously buffer and reduce shock, ensuring excellent shock-absorbing effect.

[0023] In some embodiments, the limiting column 17 is a double-headed screw, one end of which is threadedly connected to the first platform 12 or the second platform 13, and the other end passes through the first mounting plate 14 or the second mounting plate 15 and is threadedly connected with a nut 19.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, taking the guiding mechanism 1 at the incoming line position as an example, a connecting screw hole 16 connected to a stud is provided at the bottom end of the first platform 12, and a connecting through hole 110 for the stud to pass through is provided on the first mounting plate 14. The stud is a nut 19 threadedly connected through the connecting through hole 110, and the nut 19 rests against the bottom end of the first mounting plate 14. Similarly, a connecting screw hole 16 is also provided on the second platform 13, and a connecting through hole 110 corresponding to a limiting column 17 is also provided on the second mounting plate 15, so as to achieve the purpose of quick disassembly and assembly. At the same time, the nut 19 also serves to limit the first mounting plate 14 or the second mounting plate 15 from being separated from the corresponding limiting column 17, and to give an initial compression amount to the clamping spring 18 to ensure that the clamping spring 18 needs to be restored to its original shape to clamp the cable.

[0025] In some embodiments, the guiding mechanism 1 further includes swing rods 111 disposed on both sides of the guiding wheel 113. There is a first included angle between the extending direction of the swing rod 111 and the extending direction of the first gap, and the opening direction of the first included angle faces the cable inlet direction. A locking bolt 112 is disposed through the end of the swing rod 111 away from the guiding wheel 113, and the locking bolt 112 is threadedly connected to the first mounting plate 14 or the second mounting plate 15; As Figure 1 , Figure 2 and Figure 3 shown, after loosening the locking bolt 112, the swinging angle of the swing rod 111 can be adjusted, and then the distance of the first gap can be adjusted to facilitate adapting to cables with different outer diameters. After tightening the locking bolt 112, the stability of the swing rod 111 and the guiding wheel 113 is ensured.

[0026] In some embodiments, a pre - guiding pipe 22 communicating with the inside of the container 21 is provided at the end of the container 21 near the inlet position. The pre - guiding pipe 22 is L - shaped, and a guiding wheel 23 is provided at the internal corner of the pre - guiding pipe 22; As Figure 1 , Figure 2 and Figure 3 shown, the cable coming out from the inlet position will first pass through the pre - guiding pipe 22 and then enter the inside of the container 21. The guiding wheel 23 is provided to avoid the situation where the cable rubs against the inner wall of the pre - guiding pipe 22 or the container 21, and avoid the extra vibration caused by friction. When the cable enters or exits the coating solution, it will cause fluctuations in the liquid level. Entering through the pre - guiding pipe 22 and exiting through the container 21 makes the entry and exit of the cable not in the same space, thereby avoiding mutual interference during entry and exit and making the distribution of the coating solution more uniform.

[0027] In some embodiments, a second lifting mechanism 4 is provided on the side of the container 21 away from the inlet position. The second lifting mechanism 4 includes a second sleeve 41, and a lifting cylinder body 43 is slidably inserted into the second sleeve 41. The axis extending directions of the second sleeve 41 and the lifting cylinder body 43 are both the second direction. A second locking structure is provided between the second sleeve 41 and the lifting cylinder body 43, and the second locking structure is used to limit the movement of the lifting cylinder body 43; An extension rod 46 is provided on the top end of the lifting cylinder body 43 near the inlet position side. The end of the extension rod 46 away from the lifting cylinder body 43 is the outlet position, and one side surface of the top of the lifting cylinder body 43 is detachably connected to the container 21; As Figure 1 , Figure 4 and Figure 5As shown, by moving the lifting cylinder body 43 within the second sleeve 41, the vertical height of the container 21 is driven to be adjusted, facilitating the adjustment of the positions of the sintering furnace 75 and the container 21 according to the workpieces in the factory building, and facilitating the full utilization of the space in the factory building. Additionally, an extension rod 46 is provided at the top of the lifting cylinder body 43 to ensure that the wire outlet position is always above the container 21, and the guiding mechanism 1 at the wire outlet position can correctly guide the extended cable. Optionally, a first connecting plate 27 is provided on the side of the container 21 away from the front guiding pipe 22, and a second connecting plate 47 is provided on one side of the lifting cylinder body 43. At least two corresponding mounting holes are provided on both the first connecting plate 27 and the second connecting plate 47, and the detachable connection of the first connecting plate 27 and the second connecting plate 47 is achieved through a bolt-nut combination, facilitating the convenient and rapid installation and disassembly of the container 21. Optionally, the second locking structure includes a second through hole 42 provided on the second sleeve 41 and a plurality of second screw holes 44 arranged in the vertical direction. After the lifting cylinder body 43 moves, a bolt passes through the second through hole 42 and is threadedly connected to the corresponding second screw hole 44 to achieve the limiting and locking of the lifting cylinder body 43.

[0028] In some embodiments, a first lifting mechanism 3 is provided on the side of the container 21 away from the second lifting mechanism 4. The first lifting mechanism 3 includes a first sleeve 31, and a lifting rod body 33 is slidably inserted into the first sleeve 31. The axial extension directions of both the first sleeve 31 and the lifting rod body 33 are the second direction. A first locking structure is provided between the first sleeve 31 and the lifting rod body 33, and the first locking structure is used to limit the movement of the lifting rod body 33. The top of the lifting rod body 33 is the wire inlet position. As Figure 1 、 Figure 4 and Figure 5 shown, by moving the lifting rod body 33 within the first sleeve 31, the wire inlet position is driven to move synchronously, ensuring the full utilization of the vertical space in the factory area and ensuring that the wire inlet position corresponds to the upper opening position of the container 21, ensuring that the cable can enter the container 21. Optionally, the first locking structure includes a first through hole 32 provided on the first sleeve 31 and a plurality of first screw holes 34 arranged in the vertical direction. After the lifting rod body 33 moves, a bolt passes through the first through hole 32 and is threadedly connected to the corresponding first screw hole 34 to achieve the limiting and locking of the lifting rod body 33.

[0029] In some embodiments, the coating device further includes a solution replenishing mechanism 5, and the solution replenishing mechanism 5 is used to inject the coating solution into the container 21; to replenish the solution in the container 21 and ensure continuous and effective coating processing.

[0030] In some embodiments, the solution replenishing mechanism 5 includes a liquid storage tank 53, a water pump 55 is provided on one side of the liquid storage tank 53, and a liquid suction pipe 54 connected to the inlet of the water pump 55 is provided at the bottom of the liquid storage tank 53; A solution replenishment channel 45 is provided inside the second sleeve 41 and the lifting cylinder body 43.

The coating solution passes through the liquid extraction pipe 54, the water pump 55, the liquid delivery pipe 56, the solution replenishment channel 45 and the outlet pipe 25 and is sent into the container 21 to ensure a stable and continuous coating effect. Moreover, the solution replenishment channel 45 is arranged inside the lifting cylinder body 43 and the second sleeve 41, eliminating the need for additional piping and avoiding the defects of external piping being prone to damage and occupying extra space. Optionally, a collapsible hose that can be compressed and extended in the vertical direction, such as a corrugated pipe, is provided inside the second sleeve 41 and the lifting cylinder body 43. Its top end is connected to the outlet pipe 25, and its bottom end is connected to the liquid delivery pipe 56, which will not affect the normal telescoping of the second sleeve 41 and the lifting cylinder body 43. Additionally, a jack is provided at the top of the container 21, and a sealing ring is provided on the inner wall of the jack, preventing the coating solution from leaking out from the connection when the outlet pipe 25 enters the container 21. Further preferably, the outlet of the water pump 55 is connected to the liquid delivery pipe 56 through a valve, and the inlet of the water pump 55 is connected to the liquid extraction pipe 54 through a valve. Through valve operation, it is convenient to close the liquid flow for replacing and overhauling the water pump 55.
