Description

Technical Field

[0001] This invention relates to the field of molybdenum wire processing, and in particular to a molybdenum wire cleaning device. Background Technology

[0002] In the manufacturing process of molybdenum wire, the molybdenum wire is first drawn. To ensure the tension and smoothness of the molybdenum wire after drawing, a graphite emulsion lubricant (black in color) is usually coated on the surface of the molybdenum wire. After the graphite emulsion lubricant is removed by alkaline solution, the surface of the molybdenum wire is cleaned to ensure that the surface of the molybdenum wire is relatively clean, which facilitates subsequent coating operations.

[0003] Related technology can be found in Chinese Patent No. CN206535788U, which discloses a self-cleaning device for tungsten-molybdenum electrodes. The device includes a tungsten-molybdenum electrode mounted on a robotic arm and a cleaning platform. At least one cleaning abrasive disc is mounted on the cleaning platform, and the abrasive disc is fixed to the platform by a pushing mechanism. Compared to the previous method of removing the welding head and manually cleaning it, this method is much more convenient and faster.

[0004] Regarding the aforementioned technologies, when cleaning the surface of a molybdenum wire, the wire is usually passed directly through a pool filled with clean water. However, some residual graphite emulsion lubricant may remain on the surface of the wire and cannot be cleaned away by the water, resulting in poor cleaning effect. Summary of the Invention

[0005] To improve the cleaning effect on molybdenum wire, this application provides a molybdenum wire cleaning device.

[0006] This application provides a molybdenum wire cleaning device, which adopts the following technical solution:

[0007] A molybdenum wire cleaning device includes a base, a positioning platform and a cleaning box on the base, a double-layer gauze that cooperates with the molybdenum wire on the positioning platform, a pressure plate that cooperates with the positioning platform above the positioning platform, a cylinder fixedly installed on the base near the positioning platform, a positioning rod fixedly connected to the output end of the cylinder, the positioning rod being fixedly connected to the pressure plate, and a moving component for controlling the intermittent movement of the double-layer gauze on one side of the positioning platform.

[0008] By employing the above technical solution, when cleaning the molybdenum wire, a double layer of gauze is arranged on a positioning platform. The molybdenum wire passes between the two layers of gauze, and alcohol is dripped onto the gauze. The output end of the cylinder clamps the double layer of gauze between the pressure plate and the positioning platform. Then, the molybdenum wire is moved, passing sequentially through the alcohol-soaked double layer of gauze and a cleaning tank filled with clean water. The intermittent movement of the moving component facilitates changing different areas of the double layer of gauze for wiping and cleaning the molybdenum wire. Adding alcohol-soaked gauze to wipe the molybdenum wire improves the cleaning effect and results in a better overall cleaning effect.

[0009] Optionally, the base is fixedly connected to a support rod, and the moving assembly includes a take-up roller, a ratchet, a pawl, a positioning plate, a lever, a spring, and several levers. The take-up roller is rotatably connected to the support rod, and the end of the take-up roller away from the support rod is fixedly connected to the positioning plate. All levers are fixedly connected to the positioning plate, and the positioning rod is rotatably connected to the lever. The two ends of the spring are fixedly connected to the positioning rod and the lever, respectively. The end of the take-up roller near the support rod is fixedly connected to the ratchet, and the pawl cooperates with the ratchet and is rotatably connected to the support rod.

[0010] By adopting the above technical solution, the cylinder output end drives the paddle to move upward. As the paddle gradually moves upward, it drives the lever to rotate, which in turn drives the take-up roller to rotate slightly. When the take-up roller rotates, the contact position between the double-layer gauze and the molybdenum wire changes, so that the new, cleaner area of ​​the double-layer gauze comes into contact with the molybdenum wire. This makes it easier to change different areas of the double-layer gauze to wipe and clean the molybdenum wire, ensuring the cleaning effect on the molybdenum wire.

[0011] Optionally, the pressure plate has a groove and several liquid guiding holes that communicate with the groove. A vertical rod is fixedly installed on the base near the pressure plate. A top plate is fixedly connected to the vertical rod. Several plugs that cooperate with the liquid guiding holes are fixedly connected to the top plate. The top plate has a liquid filling hole corresponding to the groove.

[0012] By adopting the above technical solution, when the cylinder output end drives the pressure plate to move upward, the blocking strips on the top plate block the corresponding liquid guiding holes respectively. Then, alcohol is poured into the groove from the liquid filling hole. When the pressure plate moves downward, the blocking strips separate from the liquid guiding holes, and the alcohol is poured from the liquid guiding holes onto the double-layer gauze, which improves the convenience of adding alcohol.

[0013] Optionally, the cleaning box includes an inner box and an outer box. Both the inner box and the outer box are provided with limiting grooves that cooperate with molybdenum wires. A hydraulic pump is provided at the lower end of the inner box. The inner box is provided with a liquid inlet that cooperates with the hydraulic pump. Several support rods are fixed at the lower end of the inner box, and filter screens are provided between adjacent support rods.

[0014] By adopting the above technical solution, the limiting groove facilitates the restraint of the molybdenum wire when it enters the cleaning tank for cleaning, which helps improve the stability of the molybdenum wire during transportation. After entering the inner tank, the molybdenum wire is rinsed with clean water and then exits sequentially through the limiting groove on the side opposite to the positioning platform, making the cleaning of the molybdenum wire more convenient. The installation of a filter screen and a hydraulic pump enables water recycling, which helps save resources.

[0015] Optionally, the base is provided with an adjusting rod that cooperates with the take-up roller. The end of the take-up roller away from the support rod is provided with a circular groove, and the adjusting rod is provided with an arc-shaped opening that matches the circular groove.

[0016] By adopting the above technical solution, the arc-shaped opening is inserted into the circular groove, which helps to improve the stability of the take-up roller during rotation and ensures the cleaning effect on the molybdenum wire.

[0017] Optionally, the adjusting rod includes a thick rod and a thin rod slidably connected to the thick rod, the thin rod is connected to a bolt, and the thick rod has several through holes that mate with the bolt.

[0018] By adopting the above technical solution, the thick rod and the thin rod are slidably connected, and the thin rod and the take-up roller can be separated, making it easy to remove the dirty double-layer gauze from the take-up roller.

[0019] Optionally, the base is provided with an oven on the side near the cleaning box, and the oven has wiring holes on both sides that are compatible with molybdenum wires.

[0020] By adopting the above technical solution, the molybdenum wire is heated and dried in the oven, which facilitates the removal of residual moisture on the surface of the molybdenum wire and ensures the subsequent processing of the molybdenum wire.

[0021] Optionally, the pressure plate is made of an elastic material.

[0022] By adopting the above technical solution, the elastic material can alleviate the rigid force when the pressure plate presses down on the molybdenum wire, thus ensuring the quality of the molybdenum wire.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When cleaning the molybdenum wire, place the double-layered gauze on the positioning table. The molybdenum wire passes between the two layers of gauze. Alcohol is dripped onto the double-layered gauze. The cylinder output clamps the double-layered gauze between the pressure plate and the positioning table. Then, move the molybdenum wire, passing sequentially through the alcohol-soaked double-layered gauze and the cleaning tank containing clean water. The intermittent movement of the moving component facilitates changing different areas of the double-layered gauze for wiping and cleaning the molybdenum wire. Adding alcohol-soaked gauze to wipe the molybdenum wire improves the cleaning effect and provides a better overall cleaning result.

[0025] 2. When the cylinder output end drives the pressure plate to move upward, the blocking strips on the top plate block the corresponding liquid guide holes. Then, alcohol is poured into the groove from the liquid filling hole. The pressure plate moves downward and the blocking strips separate from the liquid guide holes. The alcohol is then poured from the liquid guide holes onto the double-layer gauze, which improves the convenience of adding alcohol. Attached Figure Description

[0033] The present application will be further described in detail below with reference to all the accompanying drawings.

[0034] This application discloses a molybdenum wire cleaning device. Example

[0035] Reference Figure 1 and Figure 2 A molybdenum wire cleaning device includes a base 1, on which a positioning platform 2 and a cleaning tank 3 are mounted. The positioning platform 2 and the cleaning tank 3 are located on the same horizontal line. A double-layered gauze 4 is mounted on the positioning platform 2 to cooperate with the molybdenum wire. To clean the molybdenum wire, the operator first places the double-layered gauze 4 on the positioning platform 2, passes the molybdenum wire through the gaps between the double-layered gauze 4, and then drips alcohol onto the double-layered gauze 4.

[0036] Reference Figure 1 and Figure 2 Above the positioning platform 2, there is a pressure plate 21 that cooperates with the positioning platform 2. A cylinder 5 is fixedly installed on the base 1 near the positioning platform 2. A positioning rod 51 is fixedly connected to the output end of the cylinder 5. The positioning rod 51 is fixedly connected to the pressure plate 21. When the operator starts the cylinder 5, the output end of the cylinder 5 retracts, causing the positioning rod 51 and the pressure plate 21 to move downwards, clamping the double-layer gauze 4 between the pressure plate 21 and the positioning platform 2. The pressure plate 21 is made of elastic material, which can alleviate the rigid force when the pressure plate 21 presses down on the molybdenum wire, reducing the probability of deformation of the molybdenum wire and facilitating the assurance of the quality of the molybdenum wire.

[0037] Reference Figure 1 and Figure 2Then, the molybdenum wire is moved along its length. As it moves, the molybdenum wire passes through a double-layered gauze 4 soaked in alcohol and a cleaning tank 3 filled with clean water. The alcohol-moistened gauze wipes the molybdenum wire, improving the cleaning effect and resulting in a better overall cleaning effect.

[0038] Reference Figure 3 and Figure 4 When the molybdenum wire is wiped in the same spot for an extended period using double-layered gauze 4, the area where the double-layered gauze 4 is located is prone to becoming quite dirty. Base 1 (refer to...) Figure 1 A support rod 11 is fixedly connected to the positioning platform 2, and a moving component 6 is provided on one side to control the intermittent movement of the double-layer gauze 4 (see reference). Figure 2 ), Mobile component 6 (see reference) Figure 2 It includes a take-up roller 61, a ratchet 62, a pawl 63, a positioning plate 64, a paddle 65, a spring 66, and six levers 67. The take-up roller 61 is rotatably connected to the upper end of the support rod 11, and one end of the double-layer gauze 4 is wound around the take-up roller 61.

[0039] Reference Figure 3 and Figure 4 The positioning rod 51 is rotatably connected to the lever 65. The two ends of the spring 66 are fixedly connected to the positioning rod 51 and the lever 65 respectively, and the spring 66 is connected to the upper surface of the lever 65. When the moving component 6 moves the double-layer gauze 4, the operator activates the cylinder 5. The output end of the cylinder 5 drives the positioning rod 51 and the lever 65 upwards. The end of the take-up roller 61 facing away from the support rod 11 is fixedly connected to the positioning disk 64. All levers 67 are fixedly connected to the positioning disk 64, and all levers 67 are set at equal angles along the circumference of the positioning disk 64. When the lever 65 moves upwards, it contacts the lever 67. As the lever 65 gradually moves upwards, it drives the lever 67 to rotate, which in turn drives the positioning disk 64 and the take-up roller 61 to rotate slightly.

[0040] Reference Figure 3 and Figure 4 When the take-up roller 61 rotates, it takes up the double-layer yarn 4, thereby changing the contact position between the double-layer yarn 4 and the molybdenum wire. This causes the new, cleaner area of ​​the double-layer yarn 4 to come into contact with the molybdenum wire, and the moving component 6 (refer to...) Figure 2 The molybdenum wire moves intermittently without moving with the double-layer gauze 4, making it easy to change different areas of the double-layer gauze 4 to wipe and clean the molybdenum wire, ensuring effective cleaning. No manual adjustment of the position of the double-layer gauze 4 is required, saving manpower and improving processing efficiency.

[0041] Reference Figure 3 and Figure 4When the output end of cylinder 5 drives the pressure plate 21 to move upward, the paddle 65 separates from the corresponding lever 67, and the pressure plate 21 continues to move upward. The pressure plate 21 has a groove 211 and multiple liquid guiding holes 212 that communicate with the groove 211. The base 1 (refer to...) Figure 1 A vertical rod 12 is fixed near the pressure plate 21. A top plate 121 is fixedly connected to the upper end of the vertical rod 12. Several blocking strips 122 that cooperate with the liquid guiding hole 212 are fixedly connected to the lower end face of the top plate 121. At this time, the blocking strips 122 on the top plate 121 are inserted into the corresponding liquid guiding hole 212, thereby blocking the liquid guiding hole 212.

[0042] Reference Figure 3 and Figure 4 The top plate 121 has a liquid filling hole 123 in the middle that corresponds to the groove 211. An alcohol bottle is placed on the upper surface of the top plate 121. The operator pours the alcohol from the bottle into the groove 211 through the liquid filling hole 123. Then, the output end of the cylinder 5 drives the pressure plate 21 to move down, thereby separating the plug 122 from the liquid guiding hole 212. The alcohol in the groove 211 is poured onto the new area of ​​the double-layer gauze 4 through the liquid guiding hole 212. Alcohol can be added to the double-layer gauze 4 without manually removing the top plate 121, making it convenient to add alcohol.

[0043] Reference Figure 3 and Figure 4 One end of the take-up roller 61 near the support rod 11 is fixedly connected to the ratchet 62. The pawl 63 engages with the ratchet 62 and is rotatably connected to the support rod 11. When the take-up roller 61 rotates, the ratchet 62 on the other side rotates simultaneously. After the ratchet 62 rotates, the pawl 63 still limits the ratchet 62 and the take-up roller 61. When the output end of the cylinder 5 moves down, it drives the positioning rod 51 and the paddle 65 to move down. When the paddle 65 abuts against the lever 67, the pawl 63 always limits the ratchet 62 and the take-up roller 61, so the take-up roller 61 will not rotate. As the paddle 65 continues to move down, the spring 66 is compressed, the paddle 65 rotates, and finally the paddle 65 separates from the lever 67.

[0044] Reference Figure 2 and Figure 4 Base 1 (refer to) Figure 1 An adjusting rod 7 is provided to cooperate with the take-up roller 61. The end of the take-up roller 61 away from the support rod 11 has a circular groove 611. The adjusting rod 7 has an arc-shaped opening 71 that matches the circular groove 611. The arc-shaped opening 71 is inserted into the circular groove 611, which can improve the stability of the take-up roller 61 when rotating, ensure the normal winding of the double-layer gauze 4, and ensure the cleaning effect on the molybdenum wire; at the same time, the arc-shaped opening 71 can limit the circular groove 611 to prevent the take-up roller 61 from deviating when rotating.

[0045] Reference Figure 2 and Figure 4The adjusting rod 7 includes a thick rod 72 and a thin rod 73 slidably connected to the thick rod 72. The lower end of the thin rod 73 is connected to a bolt 731. When there is a lot of bed gauze wrapped on the take-up roller 61, the operator separates the bolt 731 from the thick rod 72 and slides the thin rod 73 downward, thereby separating the arc-shaped opening 71 from the take-up roller 61, so that the dirty double-layer gauze 4 on the take-up roller 61 can be removed. After removal, the thin rod 73 is moved upward, and the arc-shaped opening 71 is inserted into the circular groove 611. The thick rod 72 has multiple through holes 721 along the height direction that cooperate with the bolt 731. Then, the bolt 731 is threaded through the corresponding through hole 721 and connected to the thin rod 73.

[0046] Reference Figure 1 and Figure 5 The cleaning box 3 includes an inner box 31 and an outer box 32. The inner box 31 is located inside the outer box 32. Both sides of the inner box 31 and the outer box 32 are provided with limiting grooves 33 that cooperate with the molybdenum wire. When the molybdenum wire enters the cleaning box 3 for cleaning, it passes through the limiting grooves 33 on the side of the outer box 32 and the inner box 31 near the positioning table 2 in sequence. The limiting grooves 33 facilitate the limiting of the molybdenum wire, prevent the molybdenum wire from deviating in the horizontal direction, and improve the stability of the molybdenum wire during movement and conveying.

[0047] Reference Figure 1 and Figure 5 The water level in the inner tank 31 is slightly higher than the lowest point of the limiting groove 33 in the inner tank 31. After the molybdenum wire enters the inner tank 31, it is cleaned with water and then exits sequentially from the limiting groove 33 on the side opposite to the positioning platform 2, making the cleaning of the molybdenum wire relatively convenient. At the same time, the water in the inner tank 31 flows into the outer tank 32 through the limiting groove 33 of the inner tank 31. Four support rods are fixed at the lower end of the inner tank 31, and the water level in the outer tank 32 is less than the height of the support rods.

[0048] Reference Figure 5 and Figure 6 A filter screen 314 is installed between adjacent support rods. Water entering the lower part of the inner box 31 is filtered by the filter screen 314. A hydraulic pump 311 is installed at the lower end of the inner box 31. The inner box 31 has an inlet hole 312 that cooperates with the hydraulic pump 311. Under the action of the hydraulic pump 311, the water enters the inner box 31 from the outer box 32 through the inlet hole 312, realizing the recycling of water and saving resources.

[0049] Reference Figure 1 An oven 8 is fixed on the side of the base 1 near the cleaning box 3. A heating wire is installed inside the oven 8. The oven 8 has wiring holes 81 on both sides that are compatible with the molybdenum wire. After the molybdenum wire is cleaned by the cleaning box 3, it passes through the wiring hole 81 on one side of the oven 8 and exits through the wiring hole 81 on the other side. The molybdenum wire enters the oven 8 for heating and drying, which can remove the residual moisture on the surface of the molybdenum wire and ensure the subsequent processing of the molybdenum wire.

[0050] The implementation principle of the molybdenum wire cleaning device in this application embodiment is as follows: When cleaning the molybdenum wire, the operator first places a double-layer gauze 4 on the positioning platform 2, and the molybdenum wire passes through the double-layer gauze 4. Then, alcohol is dripped onto the double-layer gauze 4. The output end of the cylinder 5 retracts, causing the positioning rod 51 and the pressure plate 21 to move downward, clamping the double-layer gauze 4 between the pressure plate 21 and the positioning platform 2. Then, the molybdenum wire is moved, passing through the alcohol-soaked double-layer gauze 4 and the cleaning tank 3 containing clean water in sequence. Increasing the use of alcohol-soaked gauze to wipe the molybdenum wire improves the cleaning effect and provides a better overall cleaning effect. The intermittent movement of the moving component 6 facilitates the replacement of different areas of the double-layer gauze 4 for wiping and cleaning the molybdenum wire, ensuring the cleaning effect of the molybdenum wire.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
