Description

Technical Field

[0001] This invention relates to the field of cable filling, specifically to a flame-retardant layer filling device for processing flame-retardant charging pile cables. Background Technology

[0002] The wire and cable industry offers a wide variety of products with diverse applications, spanning sectors such as power, petrochemicals, communications, and manufacturing. It is closely linked to all sectors of the national economy. Fire-resistant and flame-retardant cables maintain circuit integrity in the event of a fire, ensuring the safe and normal operation of critical emergency systems. Abroad, they are widely used in fire alarm systems, smoke detection systems, emergency lighting and power systems, and public address systems in large shopping malls, hospitals, offices, train stations, airports, and residential buildings. Flame-retardant cables are filled with non-combustible flame retardants such as metal oxides, achieving a fire-resistant and flame-retardant effect. To enhance the cable's waterproof and flame-retardant properties, a filling layer is typically installed inside the cable. This filling layer usually consists of inorganic flame-retardant materials such as clay, placed between the cable core and the outer protective layer to increase the overall strength and flame-retardant performance of the cable.

[0003] When using existing filling devices, one end of the cable is usually fed into the filling device manually. After adjusting the angle at various points, the other end of the cable is sent out from the outlet of the filling device. At this point, the filling device can be started. The stirring device inside the filling device can stir the flame retardant material inside the filling device. With the continuous feeding of the cable, the cable that has been coated can be sent out from the outlet of the filling device, while the cable that has not been coated will also enter the filling device for coating.

[0004] However, in the above-mentioned process, manually feeding the cable makes the entire cable coating process extremely slow. This manual feeding method results in a large amount of manual work and low efficiency. In addition, after one end of the cable is manually fed into the filling device, it needs to be manually adjusted to pull the cable out of the outlet. This method takes a lot of time to pull out the cable, which greatly reduces efficiency. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a flame-retardant layer filling device for processing flame-retardant charging pile cables, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flame-retardant layer filling device for processing flame-retardant charging pile cables, comprising a filling barrel, two sets of supports fixedly installed above the filling barrel, a rotating roller slidably arranged on one side of each of the two sets of supports, a first pulley movably arranged on one side of one set of supports, the first pulley being coaxially arranged with one set of rotating rollers, a third pulley movably arranged on one side of the other set of supports, the third pulley being movably connected to another set of rotating rollers, an installation frame fixedly installed above the filling barrel, a second pulley movably arranged above the installation frame, and the second pulley connecting the first pulley and the third pulley via a belt, two sets of clamps slidably arranged above the filling barrel, a brush cylinder installed inside the filling barrel via two sets of bearings, and multiple sets of inclined plates fixedly arranged on the outer wall of the brush cylinder.

[0007] By adopting the above technical solution, after the cable enters the inlet, the rotation of the roller will cause the cable to actively enter the filling barrel. At this time, the two sets of clamps will make the cable move vertically into the brush barrel, thus avoiding the need for manual feeding of the cable into the filling barrel and improving the efficiency of applying the flame retardant layer. At the same time, the setting of the roller and clamps will prevent the cable from moving during the process, ensuring the stability of the cable entry. In addition, by fixing the cable barrel, it is possible to prevent material leakage when working with cables of different diameters.

[0008] The present invention is further configured such that a set of brackets is provided with two sets of second springs inside, one end of the second spring is fixedly connected to a first mounting bracket, a first motor is fixedly mounted on one side of the first mounting bracket, one end of the other set of second springs is fixedly connected to a second mounting bracket, a rotating roller is rotatably mounted on the ends of the first mounting bracket and the second mounting bracket, a first pulley is rotatably mounted on the second mounting bracket, and the output end of the first motor is coaxially arranged with the rotating roller.

[0009] By adopting the above technical solution, after the first motor is started, a set of rotating rollers will rotate, and the rotation of the rotating rollers will cause the first pulley to rotate synchronously.

[0010] The invention is further configured such that two sets of second springs are provided inside another set of the brackets. One end of one set of second springs is fixedly connected to a third mounting bracket, and one end of the other set of second springs is fixedly connected to a fourth mounting bracket. A third pulley is rotatably mounted on one side of the fourth mounting bracket, and a first gear is rotatably mounted on one side of the fourth mounting bracket. The first gear and the third pulley are coaxially arranged. A second gear is rotatably mounted on one side of the fourth mounting bracket. The second gear and another set of rotating rollers are coaxially arranged, and the second gear and the first gear mesh with each other.

[0011] By adopting the above technical solution, when the first pulley rotates, the second gear will rotate synchronously through the cooperation between various parts, and the rotation between the two sets of rollers will become relative rotation.

[0012] The present invention is further configured such that a movable rod is slidably disposed inside the mounting frame, a first spring is fixedly disposed at the bottom of the movable rod, the first spring is located inside the mounting frame, and a second pulley is rotatably mounted on one side of the movable rod.

[0013] By adopting the above technical solution, the distance between the first pulley and the third pulley can be adjusted. At this time, the movable second pulley will tighten the belt to ensure the connection between the first pulley, the second pulley and the third pulley.

[0014] The present invention is further configured such that an inlet is provided above the filling barrel, and fixed cylinders are provided on both sides of the inlet. A sliding groove is provided inside the fixed cylinder, and a fixed rod is slidably arranged inside the sliding groove. A clamp is fixedly arranged at one end of the fixed rod, and a third spring is provided at the other end of the fixed rod. The third spring is located inside the sliding groove, and the lower surface of the clamp overlaps with the upper surface of the brush barrel.

[0015] By adopting the above technical solution, the two sets of clamps can be moved horizontally above the brush cylinder without rotating, and the cable can be kept from moving while being held by the clamps.

[0016] The present invention is further configured such that multiple sets of stirring rods are fixedly arranged on the outer wall of the brushing cylinder, the stirring rods are inclined, and a scraper is fixedly installed on one side of the stirring rod, and one side of the scraper is arranged to fit against the inner wall of the filling barrel.

[0017] By adopting the above technical solution, when the brush cylinder rotates, the inclined stirring rod can make the material vortex inside the filling barrel, which can fill the cable more quickly and fully.

[0018] The present invention is further configured such that multiple sets of brushing ports are provided on the outer wall of the brushing cylinder, and inclined plates are fixedly installed on the brushing ports.

[0019] By adopting the above technical solution, when the brush cylinder rotates, the inclined plate will collect the material and fill the inside of the cable through the brush port.

[0020] The invention is further configured such that a fixed cable cylinder is threadedly installed on the inner wall of the brush cylinder, the inner wall of the fixed cable cylinder is in contact with the outer wall of the cable, an external connecting cylinder is threadedly installed at the bottom of the fixed cable cylinder, the inner wall of the external connecting cylinder is flush with the inner wall of the brush cylinder, and a fifth pulley is fixedly installed on the outer wall of the external connecting cylinder.

[0021] By adopting the above technical solution, cables of different diameters can be filled with flame-retardant layers inside the same filling barrel, which is convenient and quick.

[0022] The present invention is further configured such that a feed inlet is provided on one side of the filling barrel, an observation hole is provided on the barrel body, a base is fixedly installed at the bottom of the filling barrel, a second motor is fixedly installed inside the base, a fourth pulley is fixedly installed at the output end of the second motor, and the fourth pulley is connected to a fifth pulley via a belt.

[0023] By adopting the above technical solution, the brush cylinder can be rotated inside the filling barrel after the second motor is started, so that the cable can be quickly filled with the flame retardant layer.

[0024] The present invention is further configured such that the bottom of the inner wall of the filling barrel is inclined, the bottom of the filling barrel is provided with a discharge port, the discharge port is provided with a valve, and the discharge port is located at the lowest point of the inclined bottom of the filling barrel.

[0025] By adopting the above technical solution, the bottom of the inner wall of the filling barrel is inclined during material discharge, which allows the material to be discharged quickly.

[0026] In summary, the present invention has the following main beneficial effects:

[0027] 1. This invention, through the arrangement of two sets of rotating rollers and a fixed spool, allows the cable to actively enter the filling barrel after entering the inlet, driven by the rotation of the rollers. The two sets of clamps then ensure the cable moves vertically into the material barrel, preventing manual feeding of the cable and improving the efficiency of applying the flame-retardant layer. The rotating rollers and clamps also prevent the cable from shifting during movement, ensuring the stability of the cable entry. Furthermore, the fixed spool prevents material leakage when working with cables of different diameters.

[0028] 2. The present invention, through the arrangement of the brush cylinder, scraper and inclined plate, enables the fourth and fifth pulleys to rotate after the second motor is started. When the fifth pulley rotates, the brush cylinder will rotate. When the brush cylinder rotates, the scraper can remove the material on the inner wall of the filling barrel, ensuring that the material on the inner wall is fully mixed during stirring. It also ensures that when the material is discharged, all the material will enter the discharge port from the inclined surface at the bottom of the filling barrel, without causing waste.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0044] The embodiments of the present invention will now be described.

[0045] Example 1

[0046] Flame-retardant layer filling device for processing flame-retardant charging pile cables, such as Figures 1-13 As shown, the device includes a filling barrel 1, with two sets of brackets 3 fixedly installed above the filling barrel 1. Rollers 6 are slidably arranged on one side of each set of brackets 3. A first pulley 8 is movably arranged on one side of one set of brackets 3, and the first pulley 8 is coaxially arranged with one set of rollers 6. A third pulley 15 is movably arranged on one side of the other set of brackets 3, and the third pulley 15 is movably connected to another set of rollers 6. An installation frame 9 is fixedly installed above the filling barrel 1, and a second pulley 11 is movably arranged above the installation frame 9. The second pulley 11 is connected to the first pulley 8 and the third pulley 15 through a belt. Two sets of clamps 19 are slidably arranged above the filling barrel 1.

[0047] When using this device, first place the cable 21 between the two sets of rotating rollers 6. At this time, the diameter of the cable 21 will cause the two sets of rotating rollers 6 to fit the cable 21, ensuring that the distance between the two sets of rotating rollers 6 fits the cable 21 with different diameters. When the distance between the two sets of rotating rollers 6 changes, the belt will pull the second pulley 11. At this time, the second pulley 11 will drive the moving rod 10 to move inside the mounting frame 9 under the pull. The movement of the moving rod 10 will pull the first spring 1001, ensuring that the second pulley 11 will tighten the belt.

[0048] Then, the first motor 5 is started. The rotation of the first motor 5 causes a set of rollers 6 to rotate. The rotation of the rollers 6 causes the first pulley 8 to rotate synchronously. Under the action of the belt, the second pulley 11 and the third pulley 15 rotate synchronously. The rotation of the third pulley 15 causes the first gear 16 to rotate, which in turn causes the second gear 17 to rotate. The rotation of the second gear 17 then causes another set of rollers 6 to rotate. At this point, the two sets of rollers... The roller 6 will rotate relative to the cable 21 and pull it downward. At this time, the end of the cable 21 will contact the two sets of clamps 19. The upper surface of the clamps 19 will contact the end of the cable 21 first. With the continuous movement of the cable 21, the clamps 19 will move inside the inlet 18. Under the limit of the clamps 19, the cable 21 will move vertically into the brush cylinder 20. The brush cylinder 20 is installed inside the filling barrel 1 through two sets of bearings 2001. Multiple sets of inclined plates 2005 are fixedly installed on the outer wall of the brush cylinder 20.

[0049] After the cable 21 moves to the bottom of the brush cylinder 20, turn off the first motor 5. Then, add the material into the filling tank 1 from the feed inlet 101. Then, start the second motor 201. The rotation of the second motor 201 will cause the fourth pulley 202 to rotate. Under the rotation of the fourth pulley 202, the fifth pulley 2008 will rotate synchronously. The rotation of the fifth pulley 2008 will cause the brush cylinder 20 to rotate inside the filling tank 1 through the bearing 2001. At this time, the stirring rod 2002 fixed on the outer wall of the brush cylinder 20 will stir the material inside the filling tank 1. Under the setting of the stirring rod 2002, the material will be fully mixed and stirred.

[0050] Simultaneously, the inclined stirring rod 2002 allows the material inside the filling tank 1 to move from the edge towards the center during stirring. While the brushing cylinder 20 rotates, multiple inclined plates 2005 push the material inside the filling tank 1 towards the brushing port 2004. As the brushing cylinder 20 rotates, the material can be fully coated onto the cable 21. The brushing cylinder 20 also ensures the vertical movement of the cable 21 inside the filling tank 1, guaranteeing its trajectory. To discharge the material from the filling tank 1, the pre-set valve inside the discharge port 103 is first opened. With the brushing cylinder 20 rotating, the scraper 2003 cleans the material from the inner wall of the filling tank 1, and finally, all the material is discharged through the discharge port 103.

[0051] Please see Figure 2 , Figure 6 and Figure 7A set of brackets 3 has two sets of second springs 13 inside. One end of one set of second springs 13 is fixedly connected to a first mounting bracket 4. A first motor 5 is fixedly installed on one side of the first mounting bracket 4. One end of the other set of second springs 13 is fixedly connected to a second mounting bracket 7. A rotating roller 6 is rotatably installed at the ends of the first mounting bracket 4 and the second mounting bracket 7. A first pulley 8 is rotatably installed on the second mounting bracket 7. The output end of the first motor 5 is coaxially set with the rotating roller 6, so that when the first motor 5 is started, the set of rotating rollers 6 will rotate. At this time, the rotation of the rotating roller 6 will cause the first pulley 8 to rotate synchronously.

[0052] Please see Figure 2 , Figure 6 and Figure 7 The other set of brackets 3 has two sets of second springs 13 inside. One end of one set of second springs 13 is fixedly connected to a third mounting bracket 12, and the other end of the second springs 13 is fixedly connected to a fourth mounting bracket 14. A third pulley 15 is rotatably mounted on one side of the fourth mounting bracket 14, and a first gear 16 is rotatably mounted on one side of the fourth mounting bracket 14. The first gear 16 and the third pulley 15 are coaxially arranged. A second gear 17 is rotatably mounted on one side of the fourth mounting bracket 14. The second gear 17 is coaxially arranged with another set of rotating rollers 6. The second gear 17 and the first gear 16 mesh with each other, so that when the first pulley 8 rotates, the second gear 17 will rotate synchronously through the cooperation between various parts. At this time, the rotation between the two sets of rotating rollers 6 will become relative rotation.

[0053] Please see Figure 2 , Figure 6 and Figure 7 A movable rod 10 is slidably arranged inside the mounting frame 9. A first spring 1001 is fixedly arranged at the bottom of the movable rod 10. The first spring 1001 is located inside the mounting frame 9. A second pulley 11 is rotatably mounted on one side of the movable rod 10, which allows the distance between the first pulley 8 and the third pulley 15 to be adjusted. At this time, the movable second pulley 11 will tighten the belt to ensure the connection relationship between the first pulley 8, the second pulley 11 and the third pulley 15.

[0054] Please see Figure 8 and Figure 9A cable inlet 18 is provided above the filling barrel 1. Fixed cylinders 1801 are provided on both sides of the cable inlet 18. A sliding groove 1802 is provided inside the fixed cylinder 1801. A fixed rod 1901 is slidably arranged inside the sliding groove 1802. A clamp 19 is fixedly arranged at one end of the fixed rod 1901. A third spring 1902 is arranged at the other end of the fixed rod 1901. The third spring 1902 is located inside the sliding groove 1802. The lower surface of the clamp 19 overlaps the upper surface of the brush barrel 20, which allows the two sets of clamps 19 to move horizontally above the brush barrel 20 without rotating, and ensures that the cable 21 will not move under the clamp of the clamp 19.

[0055] Please see Figure 8 and Figure 10 Multiple sets of stirring rods 2002 are fixedly installed on the outer wall of the brush cylinder 20. The stirring rods 2002 are inclined, and a scraper 2003 is fixedly installed on one side of the stirring rod 2002. The scraper 2003 is attached to the inner wall of the filling barrel 1. When the brush cylinder 20 rotates, the material can be made to vortex inside the filling barrel 1 by the inclined stirring rods 2002. At this time, the material can be filled into the cable 21 more quickly and fully.

[0056] Please see Figure 10 and Figure 11 The outer wall of the brush cylinder 20 has multiple brush ports 2004. An inclined plate 2005 is fixedly installed on the brush port 2004, so that when the brush cylinder 20 rotates, the inclined plate 2005 will collect the material and fill the material into the inside of the cable 21 through the brush port 2004.

[0057] Please see Figure 1 , Figure 2 and Figure 4 The filling barrel 1 has a feed inlet 101 on one side and an observation hole 102 on its body. A base 2 is fixedly installed at the bottom of the filling barrel 1. A second motor 201 is fixedly installed inside the base 2. A fourth pulley 202 is fixedly installed at the output end of the second motor 201. The fourth pulley 202 is connected to a fifth pulley 2008 via a belt. This allows the second motor 201 to start and cause the brush cylinder 20 to rotate inside the filling barrel 1, so that the cable 21 can quickly fill the flame retardant layer.

[0058] Please see Figure 8 The bottom of the inner wall of the filling barrel 1 is inclined, and the bottom of the filling barrel 1 is provided with a discharge port 103. A valve is pre-installed inside the discharge port 103, and the discharge port 103 is located at the lowest point of the inclined bottom of the filling barrel 1. This allows the material to be discharged quickly when the discharge port 103 is discharging material.

[0059] Example 2

[0060] Please see Figure 12 and Figure 13 The inner wall of the brush tube 20 is threaded with a fixing tube 2006, and the inner wall of the fixing tube 2006 is in contact with the outer wall of the cable 21. The bottom of the fixing tube 2006 is threaded with an outer tube 2007, and the inner wall of the outer tube 2007 is flush with the inner wall of the brush tube 20. A fifth pulley 2008 is fixedly installed on the outer wall of the outer tube 2007, which allows cables 21 of different diameters to be filled with flame retardant layer in the same filling barrel 1, which is convenient and quick.

[0061] When dealing with cables 21 of different diameters, simply replace the retaining spool 2006. At this point, find a retaining spool 2006 whose inner diameter matches the cable diameter.

[0062] The working principle of this invention is as follows: When using this device, the cable 21 is first placed between the two sets of rotating rollers 6. At this time, the diameter of the cable 21 will cause the two sets of rotating rollers 6 to fit the cable 21, ensuring that the distance between the two sets of rotating rollers 6 fits the cable 21 with different diameters. When the distance between the two sets of rotating rollers 6 changes, the belt will pull the second pulley 11. At this time, the second pulley 11 will drive the moving rod 10 to move inside the mounting frame 9 under the pull. The movement of the moving rod 10 will pull the first spring 1001, ensuring that the second pulley 11 will tighten the belt. Then, the first motor 5 is started. At this time, the rotation of the first motor 5 will cause one set of rotating rollers 6 to rotate. Under the rotation of the set of rotating rollers 6, the first belt will... When wheel 8 rotates synchronously, the second pulley 11 and the third pulley 15 will also rotate synchronously under the action of the belt. The rotation of the third pulley 15 will cause the first gear 16 to rotate, and the first gear 16 will cause the second gear 17 to rotate. The rotation of the second gear 17 will cause another set of rotating rollers 6 to rotate. At this time, the two sets of rotating rollers 6 will rotate relative to each other, pulling the cable 21 downward. At this time, the end of the cable 21 will contact the two sets of clamps 19. The upper surface of the clamps 19 will first contact the end of the cable 21. With the continuous movement of the cable 21, the clamps 19 will move inside the inlet 18. Under the limit of the clamps 19, the cable 21 will be vertically directed towards the brush. The material cylinder 20 moves inside. After the cable 21 moves to the bottom of the brush cylinder 20, the first motor 5 is turned off, and the material can be added into the filling tank 1 from the feed inlet 101. Then, the second motor 201 can be started. At this time, the rotation of the second motor 201 will cause the fourth pulley 202 to rotate. Under the rotation of the fourth pulley 202, the fifth pulley 2008 will rotate synchronously. The rotation of the fifth pulley 2008 will cause the brush cylinder 20 to rotate inside the filling tank 1 through the bearing 2001. At this time, the stirring rod 2002 fixed on the outer wall of the brush cylinder 20 will stir the material inside the filling tank 1. Under the setting of the stirring rod 2002, the material will be fully mixed and stirred, and at the same time, the inclined stirring will further enhance the effect. Rod 2002 allows the material inside the filling tank 1 to move from the edge towards the center during mixing. Simultaneously, as the brush cylinder 20 rotates, multiple inclined plates 2005 push the material inside the filling tank 1 towards the brush port 2004. This ensures thorough coating of the material onto the cable 21 during rotation. The brush cylinder 20 also ensures the vertical movement of the cable 21 within the filling tank 1, guaranteeing its trajectory. To discharge the material from the filling tank 1, the pre-set valve inside the discharge port 103 is opened. With the brush cylinder 20 rotating, the scraper 2003 cleans the material from the inner wall of the filling tank 1, and finally, all the material is discharged through the discharge port 103.
