Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, and specifically relates to a wire mesh surface cleaning device used as an electrode. Background Technology

[0002] Metal wire mesh is often used as an electrode in water electrolysis. To increase the contact area between the wire mesh and water, a honeycomb-shaped nickel layer is usually coated on the wire mesh. Before nickel powder coating, the wire mesh is usually sandblasted to roughen its surface. After roughening, a certain amount of abrasive material (sand powder) remains on the surface of the wire mesh, so surface cleaning is necessary before coating with the nickel layer.

[0003] In existing technologies, a bellows is typically installed between the nickel coating and roughening processes for cleaning the surface of wire mesh. The bellows contains a blower structure. As the wire mesh enters the bellows from the roughening equipment's outlet, the blower structure sweeps air across its surface to remove the abrasive material. However, in actual use, when the blower structure sweeps air over the wire mesh, the small particle size of the abrasive material causes some to be blown away and dispersed throughout the bellows, eventually falling back onto the wire mesh behind the blower structure. This results in a less than ideal cleaning effect and poor practicality. Summary of the Invention

[0004] This invention provides a wire mesh surface cleaning device for use as an electrode, which aims to solve the problem of poor practicality of existing wire meshes due to poor cleaning effect after roughening.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a wire mesh surface cleaning device used as an electrode, comprising:

[0006] The housing has a cleaning cavity and is provided with an inlet and an outlet communicating with the cleaning cavity; the inlet is also used to communicate with the discharge port of the roughening equipment.

[0007] The first cleaning mechanism is disposed in the cleaning cavity and located at the inlet. It is used to guide the wire mesh entering the cleaning cavity through the inlet, and at the same time blow the abrasive material attached to the surface of the wire mesh into the deburring equipment through the inlet.

[0008] The second cleaning mechanism is located in the cleaning cavity and is positioned behind the first cleaning mechanism in the direction of wire mesh transmission. It is used to guide the wire mesh transmitted by the first cleaning mechanism and scrape off the residual spray material on the surface of the wire mesh.

[0009] A blower mechanism is disposed in the cleaning cavity and located at the outlet, and is used to sweep the wire mesh that is about to be discharged from the cleaning cavity.

[0010] In one possible implementation, the first cleaning mechanism includes an upper baffle, a lower baffle, and a guide air sweeping assembly; the upper baffle is disposed above the inlet and fixedly connected to the inner wall of the housing; the lower baffle is located below the inlet and fixedly connected to the inner wall of the housing, the lower baffle and the upper baffle enclose an auxiliary sub-cavity in the cleaning cavity, and a passage is formed between the lower baffle and the upper baffle; the guide air sweeping assembly is disposed in the auxiliary sub-cavity and located at the passage, for winding the wire mesh, and simultaneously blowing air onto the surface of the wire mesh in the opposite direction of wire mesh transmission.

[0011] In one possible implementation, the guiding air-sweeping assembly includes a rotating air duct, a fan, a sleeve, rolling bearings, and a first adjusting structure. The rotating air duct is rotatably mounted on the housing along the width direction of the wire mesh. The rotating air duct has an internal air passage chamber. An air inlet communicating with the air passage chamber is located at one end of the rotating air duct, and a long air outlet communicating with the air passage chamber is located on the side wall of the rotating air duct, the long air outlet being arranged along the axial direction of the rotating air duct. The fan is connected to the air inlet. The sleeve is fitted onto the rotating air duct, and ventilation openings are evenly distributed on the side wall of the sleeve. The sleeve is used for winding the wire mesh. Two rolling bearings are provided, located at opposite ends of the sleeve. The inner ring of each rolling bearing is interference-fitted with the rotating air duct, and the outer ring is interference-fitted with the sleeve. The first adjusting structure is mounted on the housing and connected to the other end of the rotating air duct, used to adjust the rotation angle of the rotating air duct to control the angle between the long air outlet and the wire mesh.

[0012] In one possible implementation, the first adjustment structure includes a fixed base, a first worm gear, and a first worm; the fixed base is fixed to the outer wall of the housing; the first worm gear is coaxially connected to the rotating air duct; the first worm is rotatably mounted on the fixed base and meshes with the first worm gear.

[0013] In one possible implementation, the second cleaning mechanism includes a guide roller and a scraping assembly; the guide roller is rotatably mounted on the housing along the width direction of the wire mesh, and the height of the guide roller is higher than the height of the guide sweeping assembly; the scraping assembly is located between the guide roller and the guide sweeping assembly, and abuts against the upper surface of the wire mesh, for scraping off the residual spray material on the upper surface of the wire mesh as it is passed along.

[0014] In one possible implementation, the scraping assembly includes a suspension structure, a connecting seat, a connecting structure, a scraper, and a second adjustment structure; the suspension structure is mounted on the housing; the connecting seat is located below the suspension structure and connected to it; the connecting structure is rotatably mounted on the connecting seat along the width direction of the wire mesh, and the connecting structure has two connecting ends; the scraper is detachably connected to the two connecting ends, and the scraper is used to scrape off residual spray material on the surface of the wire mesh; the second adjustment structure is mounted on the connecting seat and is used to adjust the synchronous rotation of the connecting structure and the scraper so that the scraper is parallel to the wire mesh.

[0015] In one possible implementation, the scraper has a V-shaped structure.

[0016] In one possible implementation, the connecting structure includes a rotating rod and a hinge seat; the rotating rod is rotatably mounted on the connecting seat along the width direction of the wire mesh, and both ends of the rotating rod extend to the sides of the connecting seat; two hinge seats are provided, and the two hinge seats are respectively hinged to the two extended ends of the rotating rod, with their hinge axes perpendicular to the rotation axis of the rotating rod, and the connecting end is located on the hinge seat.

[0017] In one possible implementation, the second adjusting structure includes a second worm gear and a second worm; the second worm gear is located in the connecting seat and coaxially connected to the rotating rod; the second worm is rotatably mounted on the connecting seat and meshes with the second worm gear.

[0018] In one possible implementation, the hoisting structure includes a fixed frame, a slide block, a lead screw, and a servo motor. The fixed frame is fixed to the housing and has two guide rods spaced apart along the width direction of the wire mesh, each guide rod being positioned along the horizontal direction of the wire mesh transmission. The slide block is slidably mounted on the two guide rods. The lead screw is located between the two guide rods and rotatably mounted on the fixed frame, and is helically connected to a nut portion mounted on the slide block. The servo motor is fixed to the fixed frame, and its power output end is poweredly connected to one end of the lead screw.

[0019] In this implementation, a first cleaning mechanism, a second cleaning mechanism, and a blower mechanism are sequentially arranged in the housing. As the wire mesh is transferred within the cleaning cavity, its surface is cleaned in segments, effectively ensuring the cleaning effect. Furthermore, the first cleaning mechanism blows most of the abrasive material adhering to the wire mesh into the roughening device, preventing the abrasive material from spreading within the cleaning cavity and further guaranteeing the cleaning effect. This design is highly practical. Attached Figure Description

Detailed Implementation

[0028] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0029] Please refer to the following: Figures 1 to 6The present invention will now describe a wire mesh surface cleaning device for use as an electrode. The wire mesh surface cleaning device includes a housing 10, a first cleaning mechanism 20, a second cleaning mechanism 30, and a blower 232. The housing 10 has a cleaning cavity 11 and is provided with an inlet 12 and an outlet 13 communicating with the cleaning cavity 11. The inlet 12 can also communicate with the discharge port of a roughening device. The first cleaning mechanism 20 is disposed in the cleaning cavity 11 and located at the inlet 12, and can guide the wire mesh entering the cleaning cavity 11 through the inlet 12, while simultaneously blowing the spray material adhering to the surface of the wire mesh into the roughening device through the inlet 12. The second cleaning mechanism 30 is disposed in the cleaning cavity 11 and located behind the first cleaning mechanism 20 in the direction of wire mesh transmission, and can guide the wire mesh transmitted by the first cleaning mechanism 20, while simultaneously scraping off the spray material remaining on the surface of the wire mesh. The blower 232 is installed in the cleaning cavity 11 and located at the outlet 13, and can sweep the wire mesh that is about to be discharged from the cleaning cavity 11.

[0030] The wire mesh surface cleaning device provided in this embodiment, compared with the prior art, has a first cleaning mechanism 20, a second cleaning mechanism 30, and a blower 232 sequentially arranged in the housing 10. This allows for segmented cleaning of the wire mesh surface as it is transferred within the cleaning cavity 11, effectively ensuring the cleaning effect. Furthermore, the first cleaning mechanism 20 blows most of the abrasive adhering to the wire mesh into the roughening equipment, preventing the abrasive from spreading within the cleaning cavity 11 and further guaranteeing the cleaning effect. This device is highly practical.

[0031] In some embodiments, the first cleaning mechanism 20 described above may employ, for example... Figures 2 to 4 The structure shown. See also Figures 2 to 4 The first cleaning mechanism 20 includes an upper baffle 21, a lower baffle 22, and a guide air sweeping assembly 23. The upper baffle 21 is located above the inlet 12 and is fixedly connected to the inner wall of the housing 10. The lower baffle 22 is located below the inlet 12 and is fixedly connected to the inner wall of the housing 10. The lower baffle 22 and the upper baffle 21 enclose an auxiliary sub-cavity 24 in the cleaning cavity 11, and a passage is formed between the lower baffle 22 and the upper baffle 21. The guide air sweeping assembly 23 is located in the auxiliary sub-cavity 24 and at the passage, allowing the wire mesh to be wound around it, while simultaneously blowing air onto the surface of the wire mesh in the opposite direction of the wire mesh transmission.

[0032] The auxiliary sub-cavity 24 formed by the upper baffle 21 and the lower baffle 22 enclosing the cleaning cavity 11 can effectively prevent the spray material attached to the wire mesh from spreading throughout the cleaning cavity 11 under the blowing of the guide sweeping assembly 23. At the same time, because the auxiliary sub-cavity 24 is connected to the roughening equipment, the spray material can be blown back into the roughening equipment, effectively reducing the loss of spray volume.

[0033] It should be noted that a connecting port can be opened on the housing 10. The connecting port is located at the bottom of the auxiliary sub-cavity 24 and is connected to the roughening equipment, so that the spray material falling into the auxiliary sub-cavity 24 can return to the roughening equipment.

[0034] In some embodiments, the aforementioned guide air sweeping assembly 23 may employ, for example... Figures 3 to 4 The structure shown. See also Figures 3 to 4 The guide air sweeping assembly 23 includes a rotating air duct 231, a fan 232, a sleeve 233, a rolling bearing 234, and a first adjusting structure 235. The rotating air duct 231 is rotatably mounted on the housing 10 along the width direction of the wire mesh. The rotating air duct 231 has an internal air passage chamber 236. An air inlet communicating with the air passage chamber 236 is located at one end of the rotating air duct 231, and a long air outlet 237 communicating with the air passage chamber 236 is also located on the side wall of the rotating air duct 231, arranged along the axial direction of the rotating air duct 231. The fan 232 is connected to the air inlet. The sleeve 233 is fitted onto the rotating air duct 231, and ventilation openings are evenly distributed on the side wall of the sleeve 233. The sleeve 233 allows the wire mesh to be wound around it. Two rolling bearings 234 are provided, located at opposite ends of the sleeve 233. The inner ring of each rolling bearing 234 is interference-fitted with the rotating air duct 231, and the outer ring is interference-fitted with the sleeve 233. A first adjusting structure 235 is provided on the housing 10 and connected to the other end of the rotating air duct 231, which can adjust the rotation angle of the rotating air duct 231 to control the angle between the elongated air outlet 237 and the wire mesh.

[0035] Because the sleeve 233 is rotatably connected to the rotating air duct 231 via the rolling bearing 234, the sleeve 233 can rotate as the wire mesh is transferred. However, because the rotating air duct 231 and the elongated air outlet 237 are fixed, the air blown out of the elongated air outlet 237 can act on the wire mesh through the ventilation opening. In addition, because of the cylindrical structure of the rotating air duct 231, the air blown out of the elongated air outlet 237 is tilted downwards, which can give the abrasive material attached to the wire mesh a downward component force, and at the same time give the abrasive material attached to the wire mesh a thrust in the opposite direction of the transfer to the wire mesh, which can ensure that the abrasive material falls below the wire mesh and can also ensure that the abrasive material is blown into the roughening equipment.

[0036] In some embodiments, the first adjustment component described above may employ, for example... Figure 4 The structure shown. See also Figure 4The first adjusting structure 235 includes a fixed base 2351, a first worm gear, and a first worm 2353. The fixed base 2351 is fixed to the outer wall of the housing 10. The first worm gear is coaxially connected to the rotating air duct 231. The first worm 2353 is rotatably mounted on the fixed base 2351 and meshes with the first worm gear. Both the first worm gear and the first worm 2353 need to be installed in the fixed base 2351 to ensure the rotation adjustment of the rotating air duct 231, thereby adjusting the angle between the elongated air outlet 237 and the wire mesh, and adjusting the wind force acting on the wire mesh. When the angle between the wind blown from the elongated air outlet 237 and the wire mesh is large, the distance between the wind blown from the elongated air outlet 237 and the wire mesh is relatively short, and the wind force acting on the wire mesh is large. When the angle between the wind blown from the elongated air outlet 237 and the wire mesh is small, the distance between the wind blown from the elongated air outlet 237 and the wire mesh is relatively long, and the wind force acting on the wire mesh is small. That is, the mutual conversion between horizontal wind force and vertical force.

[0037] In some embodiments, the second cleaning mechanism 30 described above may employ, for example... Figures 1 to 2 The structure shown. See also Figures 1 to 2 The second cleaning mechanism 30 includes a guide roller 31 and a scraping assembly 32. The guide roller 31 is rotatably mounted on the housing 10 along the width direction of the wire mesh, and its height is higher than that of the guide sweeping assembly 23. The scraping assembly 32 is located between the guide roller 31 and the guide sweeping assembly 23, and abuts against the upper surface of the wire mesh. As the wire mesh is moved, it scrapes off any residual spray material on the upper surface. The guide roller 31 guides the wire mesh, resulting in an inclined arrangement of the wire mesh between the guide sweeping assembly 23 and the guide roller 31. This structure allows some residual spray material on the wire mesh to slide off directly under gravity. The scraping assembly 32 acts directly on the wire mesh, scraping off the spray material and further ensuring the cleaning effect of the wire mesh.

[0038] In some embodiments, the scraping component 32 described above may employ, for example... Figures 5 to 6 The structure shown. See also Figures 5 to 6 The scraping assembly 32 includes a lifting structure 33, a connecting seat 34, a connecting structure 35, a scraper 36, and a second adjusting structure 37. The lifting structure 33 is mounted on the housing 10. The connecting seat 34 is located below and connected to the lifting structure 33. The connecting structure 35 is rotatably mounted on the connecting seat 34 along the width direction of the wire mesh, and has two connecting ends. The scraper 36 is detachably connected to the two connecting ends and can scrape off residual spray material from the wire mesh surface. The second adjusting structure 37 is mounted on the connecting seat 34 and can adjust the synchronous rotation of the connecting structure 35 and the scraper 36 so that the scraper 36 is parallel to the wire mesh.

[0039] The scraper 36 is connected to the connecting seat 34 via the connecting structure 35. The tilt of the scraper 36 can be adjusted via the second adjusting structure 37, ensuring that the scraper 36 adapts to the tilt angle of the wire mesh and is easy to adjust. The hanging structure 33 ensures the connection to the connecting seat 34.

[0040] In some embodiments, the scraper 36 may be as follows: Figures 5 to 6 The structure shown. See also Figures 5 to 6 The scraper 36 has a V-shaped structure, which allows the scraped material to move to both sides along the width of the wire mesh and then fall off on both sides of the wire mesh, ensuring the cleaning effect.

[0041] In some embodiments, the connection structure 35 described above may adopt the following form: Figures 5 to 6 The structure shown. See also Figures 5 to 6 The connecting structure 35 includes a rotating rod 351 and a hinge seat 352. The rotating rod 351 is rotatably mounted on the connecting seat 34 along the width direction of the wire mesh, with both ends of the rotating rod 351 extending to the sides of the connecting seat 34. Two hinge seats 352 are provided, each hinged to one of the two extended ends of the rotating rod 351, with their hinge axes perpendicular to the rotation axis of the rotating rod 351. The connecting ends are located on the hinge seats 352. The rotating rod 351 ensures a rotatable connection with the connecting seat 34, while the hinge seats 352 can rotate at both ends of the rotating rod 351. This structure facilitates the connection of the scraper 36, compensates for manufacturing errors, and can accommodate the shape of the scraper 36.

[0042] In some embodiments, the second adjustment structure 37 described above can be as follows: Figures 5 to 6 The structure shown. See also Figures 5 to 6 The second adjusting structure 37 includes a second worm gear 371 and a second worm 372. The second worm gear 371 is located in the connecting seat 34 and is coaxially connected to the rotating rod 351. The second worm 372 is rotatably mounted on the connecting seat 34 and meshes with the second worm gear 371. The second worm gear 371 and the second worm 372 can ensure the adjustment of the inclination of the scraper 36 to ensure adaptation to the wire mesh and facilitate the cleaning effect of the wire mesh.

[0043] In some embodiments, the aforementioned hoisting structure 33 may adopt the following... Figures 5 to 6 The structure shown. See also Figures 5 to 6The hoisting structure 33 includes a fixed frame 331, a slide block 332, a lead screw 333, and a servo motor 334. The fixed frame 331 is fixed to the housing 10 and has two guide rods spaced apart along the width of the wire mesh. Each guide rod is positioned along the horizontal direction of the wire mesh transmission. The slide block 332 is slidably mounted on the two guide rods. The lead screw 333 is located between the two guide rods and rotatably mounted on the fixed frame 331. The lead screw 333 is helically connected to a nut portion mounted on the slide block 332. The servo motor 334 is fixed to the fixed frame 331, and its power output end is poweredly connected to one end of the lead screw 333. The servo motor 334 drives the lead screw 333, which in turn moves the slide block 332, ensuring the movement of the scraper 36. In actual production, if the tension on the wire mesh surface is too high and the scraper 36 is fixed, the wire mesh may tear. In this structure, the servo motor 334 can be electrically connected to the controller on the production line. The contact force between the scraper 36 and the wire mesh can be adjusted at any time by the wire mesh tension, which can ensure the cleaning effect of the wire mesh and prevent damage to the wire mesh.

[0044] In some embodiments, the blower 232 can adopt an existing sweeping structure. Alternatively, the rotating air duct 231 can be fixed to the housing 10, with the elongated air outlet 237 facing the wire mesh. Because there is very little spray material remaining on the surface of the wire mesh at the outlet 13, the blower 232 can also prevent the spray material from overflowing at the outlet 13.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
