A coating device for processing ultra-light fluoroplastic extruded cables and its use method

Abstract

The present invention discloses a coating device for processing ultra-light fluoroplastic extruded cables and a method for using the same. The present invention arranges a container below a sintering furnace and provides three guiding mechanisms, so that the cable penetrates into the container and then moves upward into the sintering furnace, thereby realizing vertical immersion and vertical sintering. Firstly, the present invention avoids the problem in the prior art that the tank body is too long and the sintering furnace is arranged on one side of the coating tank body, resulting in excessive space occupation. Secondly, the solution hanging on the surface of the cable insulation will not move to one side, but will flow downward as a whole, thereby ensuring that the coating on the insulation surface is evenly distributed and the coating thickness meets the standard. During the travel of the cable, the contraction of the compression spring can absorb part of the vibration energy of the cable, thereby reducing the vibration during the transportation of the cable and preventing the solution on the insulation surface from flowing due to the influence of vibration, thereby ultimately causing the problem of uneven coating distribution on the insulation surface.

Description

Technical Field

[0002] Ultra-light fluoroplastic extruded cable is a type of cable, and its insulation adopts polytetrafluoroethylene coating. The polytetrafluoroethylene surface coating can effectively homogenize the electric field and reduce the impact of mechanical noise on the product. The existing coating method is to immerse the cable to be processed into a polytetrafluoroethylene solution, and then sinter it in a sintering furnace to complete the coating process. Because the solution has good fluidity and the insulation surface of the ultra-light fluoroplastic extruded cable is smooth, the existing production line is a pay-off device, coating device, sintering device and take-up device. The machines are all placed horizontally and arranged in a line.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The present invention places the container below the sintering furnace and provides three guiding mechanisms, so that the cable can penetrate into the container and then move upward into the sintering furnace, realizing vertical immersion and vertical sintering. Firstly, it avoids the problems of the existing technology that the tank body is too long and the sintering furnace is located on one side of the coating tank body, resulting in excessive space occupation. Secondly, the solution hanging on the cable insulation surface will not move to one side, but will flow downward as a whole, ensuring that the coating on the insulation surface is evenly distributed and the coating thickness meets the requirements.

[0033] 2. A buffer assembly is provided. Under the action of the compression spring, the cable is compressed by the staggered guide wheels. During the cable travel, the contraction of the compression spring can absorb part of the cable's vibration energy, reducing the vibration during cable transportation and preventing the solution on the insulation surface from flowing due to the vibration, which ultimately causes the problem of uneven coating distribution on the insulation surface. Furthermore, the buffer assembly can use studs, connecting screw holes and nuts to quickly assemble the platform and mounting plate, making installation convenient.

[0034] 3. A guide wheel, a rocker arm, and a locking bolt are provided. After loosening the locking bolt, the swing angle of the rocker arm can be adjusted, thereby adjusting the spacing of the first gap to facilitate adaptation to cables of different outer diameters. After tightening the locking bolt, the stability of the rocker arm and the guide wheel is ensured.

[0035] 4. A first lifting mechanism and a second lifting mechanism are provided. The vertical height of the container is adjusted by moving the lifting cylinder in the second sleeve, and the incoming line position is moved synchronously by moving the lifting rod in the first sleeve, ensuring that the vertical space of the factory is fully utilized and that the incoming line position corresponds to the opening position on 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 to ensure that the outgoing line position is always above the container, ensuring the stable installation of each guide mechanism.

[0036] 5. A solution replenishing mechanism is set up. When the coating solution content in the container is lower than the preset value, the water pump will extract the coating solution in the liquid storage tank and send it into the container through the liquid extraction pipe, water pump, liquid delivery pipe, solution replenishing channel and liquid outlet pipe to ensure a stable and continuous coating effect. The solution replenishing channel is set inside the lifting cylinder and the second sleeve, and no additional pipeline is required. It also does not have the defects of external pipelines being easily damaged and occupying additional space.

[0037] It should be understood that the contents described in the summary of the invention are not intended to limit the key or important features of the embodiments of the present invention, nor are they intended to limit the scope of the present invention. Other features of the present invention will become readily understood through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0056] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0057] Example 1

[0058] 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:

[0059] The coating mechanism 2 includes a container 21 disposed below the sintering furnace 75. The container 21 contains a coating solution. A wire outlet is provided above one side of the container 21 along the first direction. A wire inlet is provided on the side of the container 21 away from the wire outlet along the first direction.

[0060] Three guide mechanisms 1 are respectively provided on the bottom surface of the container 21, at the outlet position, and at the inlet position. Each guide mechanism 1 includes a first gap for clamping the cable. The first gaps corresponding to the guide mechanisms 1 at the inlet position and the bottom surface of the container 21 extend in a direction parallel to the first direction, while the first gaps corresponding to the guide mechanisms 1 at the outlet position extend in a direction parallel to the second direction.

[0061] The first platform 12 and the second platform 13 are respectively provided on both sides of the first gap, and the first guide wheel group and the second guide wheel group are respectively provided on the sides close to each other. The first guide wheel group and the second guide wheel group each include a plurality of guide wheels 113 arranged along the extension direction of the first gap. The plurality of guide wheels 113 of the first guide wheel group and the plurality of guide wheels 113 of the second guide wheel group are staggered, and a first gap is formed between the two groups of guide wheels 113. The axis extension direction of each guide wheel 113 is the third direction, and the first direction, the second direction and the third direction are perpendicular to each other; wherein, the first direction is Figure 1 The left and right directions in the second direction are Figure 1 The up and down directions in the third direction are Figure 1 In the front-to-back direction, in addition, a connecting beam 11 is provided between the first platform 12 and the second platform 13 to ensure that the relative position between the two remains stable and to ensure the stability of the guide mechanism 1 after assembly;

[0062] A plurality of buffer components are installed on both the first platform 12 and the second platform 13, each buffer component being used to reduce vibration of the cable along a fourth direction. The fourth direction, the third direction, and the extension direction of the first gap are mutually perpendicular. The fourth direction changes with the installation position of the guide mechanism 1 and is parallel to the normal direction of the first platform 12 and the second platform 13.

[0063] like Figure 1 、 Figure 2 and Figure 3 As shown, the cable is sequentially passed through the first gap of the guide mechanism 1 at the incoming line position, the first gap of the guide mechanism 1 inside the container 21, and finally through the first gap of the guide mechanism 1 at the outgoing line position, thereby achieving vertical immersion and vertical sintering. Firstly, the problem of the existing technology in which the tank body is too long and the sintering equipment is located on one side of the coating tank body, resulting in excessive space occupation, is avoided. Secondly, the solution hanging on the surface of the cable insulation does not move to one side, but flows downward as a whole, ensuring that the coating on the insulation surface is evenly distributed and the coating thickness meets the standard.

[0064] Furthermore, due to the buffer component, the cable is compressed by the staggered guide wheels 113, which absorbs part of the cable's vibration energy during its movement, reduces the vibration during cable transportation, and prevents the solution on the insulating surface from flowing due to the vibration, ultimately causing the problem of uneven coating distribution on the insulating surface.

[0065] In some embodiments, the buffer assembly includes a plurality of limiting columns 17 arranged and distributed along the first gap extension direction at the ends close to each other of the first platform 12 and the second platform 13. The limiting column 17 located on the first platform 12 is movably sleeved with a first mounting plate 14 at an end away from the first platform 12, and the limiting column 17 located on the second platform 13 is movably sleeved with a second mounting plate 15 at an end away from the second platform 13. 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. 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.

[0066] Each guide wheel 113 of the first guide wheel group is mounted on the first mounting plate 14, and each guide wheel 113 of the second guide wheel group is mounted on the second mounting plate 15;

[0067] 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, thereby alleviating or completely preventing 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 absorb 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 absorb shock, thereby ensuring excellent shock absorption effect.

[0068] 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 to the nut 19.

[0069] like Figure 1 、 Figure 2 and Figure 3 As shown, taking the guiding mechanism 1 at the incoming line position as an example, the bottom end of the first platform 12 is provided with a connecting screw hole 16 connected to the stud, and the first mounting plate 14 is provided with a connecting through hole 110 for the stud to pass through. The stud is a nut 19 threaded through the connecting through hole 110, and the nut 19 is against the bottom end of the first mounting plate 14. Similarly, the second platform 13 is also provided with a connecting screw hole 16, and the second mounting plate 15 is also provided with a connecting through hole 110 corresponding to the limiting column 17, 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 the compression spring 18 an initial compression amount to ensure that the compression spring 18 needs to return to its original shape to compress the cable.

[0070] In some embodiments, the guide mechanism 1 further includes a swing rod 111 disposed on both sides of the guide wheel 113. A first angle is formed between the extension direction of the swing rod 111 and the extension direction of the first gap. The opening direction of the first angle is toward the cable feed direction. A locking bolt 112 is provided through the end of the swing rod 111 away from the guide wheel 113. The locking bolt 112 is threadedly connected to the first mounting plate 14 or the second mounting plate 15.

[0071] like Figure 1 、 Figure 2 and Figure 3 As shown, after loosening the locking bolt 112, the swing angle of the rocker arm 111 can be adjusted, thereby adjusting the spacing of the first gap to facilitate adaptation to cables with different outer diameters. After tightening the locking bolt 112, the stability of the rocker arm 111 and the guide wheel 113 is ensured.

[0072] In some embodiments, a front guide pipe 22 communicating with the interior of the container 21 is provided near the inlet position of the container 21. The front guide pipe 22 is L-shaped, and a guide wheel 23 is provided at the inner corner of the front guide pipe 22.

[0073] like Figure 1 、 Figure 2 and Figure 3As shown, the cable coming out from the line entry position will first pass through the front guide tube 22 and then enter the container 21, and a guide wheel 23 is provided to avoid friction between the cable and the front guide tube 22 or the inner wall of the container 21, so as to avoid additional vibration caused by friction. When the cable enters or extends out of the coating solution, it will cause fluctuations in the liquid level. The cable enters through the front guide tube 22 and then extends through the container 21, so that the cable entering and extending the liquid level are not in the same space, thereby avoiding mutual interference when entering and exiting, and making the distribution of soil bees more uniform.

[0074] In some embodiments, a second lifting mechanism 4 is provided on the side of the container 21 away from the incoming line position. The second lifting mechanism 4 includes a second sleeve 41. A lifting cylinder 43 is slidably inserted into the second sleeve 41. The axes of the second sleeve 41 and the lifting cylinder 43 extend in the second direction. A second locking structure is provided between the second sleeve 41 and the lifting cylinder 43. The second locking structure is used to limit the movement of the lifting cylinder 43.

[0075] An extension rod 46 is provided at the top of the lifting cylinder 43 near the line inlet position, and the end of the extension rod 46 away from the lifting cylinder 43 is the line outlet position. A side surface of the top of the lifting cylinder 43 is detachably connected to the container 21;

[0076] like Figure 1 、 Figure 4 and Figure 5 As shown, by moving the lifting cylinder 43 in the second sleeve 41, the vertical height of the container 21 is driven to be adjusted, so that the position of the sintering furnace 75 and the container 21 can be adjusted according to the workpiece in the factory, so as to make full use of the space in the factory. In addition, an extension rod 46 is provided at the top of the lifting cylinder 43 to ensure that the outlet position is always above the container 21, and the guiding mechanism 1 at the 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 guide tube 22, and a second connecting plate 47 is provided on one side of the lifting cylinder 43. Each of the connecting plate 27 and the second connecting plate 47 is provided with at least two corresponding mounting holes, and the detachable connection between the first connecting plate 27 and the second connecting plate 47 is achieved by a combination of bolts and nuts, so as to facilitate convenient and quick 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 a vertical direction. After the lifting cylinder 43 moves, the bolt passes through the second through hole 42 and is threadedly connected to the corresponding second screw hole 44 to achieve restricted locking of the lifting cylinder 43.

[0077] 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. A lifting rod 33 is slidably inserted into the first sleeve 31. The axes of the first sleeve 31 and the lifting rod 33 extend in the second direction. A first locking structure is provided between the first sleeve 31 and the lifting rod 33. The first locking structure is used to limit the movement of the lifting rod 33. The top of the lifting rod 33 is the line entry position.

[0078] like Figure 1 、 Figure 4 and Figure 5 As shown, by the movement of the lifting rod body 33 in the first sleeve 31, the incoming line position is driven to move synchronously, ensuring that the vertical space of the factory is fully utilized, and ensuring that the incoming line position corresponds to the opening position on the container 21, ensuring that the cable can enter the interior of 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 is passed through the first through hole 32 and is threadedly connected to the corresponding first screw hole 34 to achieve restricted locking of the lifting rod body 33.

[0079] In some embodiments, the coating device further includes a solution replenishing mechanism 5, which is used to inject coating solution into the interior of the container 21; thereby replenishing the solution in the container 21 to ensure continuous and effective coating processing.

[0080] 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 extraction pipe 54 connected to the inlet of the water pump 55 is provided at the bottom end of the liquid storage tank 53 ;

[0082] like Figure 1 、 Figure 4 、 Figure 5 and Figure 6As shown, the water pump 55 will extract the coating solution in the liquid storage tank 53, and the coating solution will be sent into the container 21 through the liquid extraction pipe 54, the water pump 55, the liquid delivery pipe 56, the solution replenishment channel 45 and the liquid outlet pipe 25 to ensure a stable and continuous coating effect. The solution replenishment channel 45 is arranged inside the lifting cylinder 43 and the second sleeve 41, and no additional pipelines are required. It also does not have the defects of external pipelines being easily damaged and occupying additional space. Optionally, a foldable hose that can be compressed and extended in the vertical direction is provided inside the second sleeve 41 and the lifting cylinder 43. , such as a bellows, the top of which is connected to the liquid outlet pipe 25 and the bottom end is connected to the liquid delivery pipe 56, which will not affect the normal expansion and contraction of the second sleeve 41 and the lifting cylinder 43. In addition, a socket is provided on the top of the container 21, and a sealing ring is provided on the inner wall of the socket to prevent the coating solution from seeping out from the connection after the liquid outlet pipe 25 reaches the inside of 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. The valve operation is convenient for closing the liquid flow and replacing the water pump 55 for maintenance.

[0083] In some embodiments, the container 21 is embedded with an observation window 24, such as Figure 1 and Figure 4 As shown, it is convenient to observe the solution content inside the container 21.
