Description

Technical Field

[0001] The invention relates to the technical field of spraying devices, and in particular to a surface treatment device and process for an aluminum single plate for a curtain wall. Background Art

[0002] Aluminum veneer for curtain wall is a curtain wall material made of aluminum alloy sheet, mainly used for decoration and protection of building exterior walls. It can not only enhance the appearance of the building, but also effectively protect the building from erosion by the external environment. When processing aluminum veneer for curtain wall, its surface needs to be sprayed with paint. Spraying paint can protect the metal surface from erosion by moisture, oxygen and other corrosive substances, prolong the service life of the metal, and the coating can provide various colors and gloss to improve the appearance of metal products.

[0003] Most of the aluminum veneers used for curtain walls are flat, which is convenient for spraying. No matter it is automatic spraying by a machine or manual spraying, by moving the nozzle vertically up and down, the distance between the nozzle and the aluminum veneer can be well controlled to remain relatively equal, thereby relatively ensuring the uniformity of the spray coating. However, some aluminum veneers are arc-shaped or wavy. When spraying this type of aluminum veneer, it is not easy to control the distance between the nozzle and the aluminum veneer, which leads to uneven spray coating. Moreover, in the process of transferring the aluminum veneer from one process to another, dust will fall on the surface of the aluminum veneer, and this dust will also affect the spraying effect. Summary of the invention

[0004] 1. Purpose of the invention In view of this, the purpose of the present invention is to propose a surface treatment device and process for aluminum veneers for curtain walls. The technical problem to be solved is that most of the existing aluminum veneers for curtain walls are flat, and this type of aluminum veneer is convenient for spraying. Whether it is automatic spraying by a machine or manual spraying, by vertically moving the nozzle up and down, the distance between the nozzle and the aluminum veneer can be well controlled to be maintained at a relatively equal distance, thereby relatively ensuring the uniformity of the spray coating. However, some aluminum veneers are arc-shaped or wavy. When spraying this type of aluminum veneer, it is not easy to control the distance between the nozzle and the aluminum veneer, which leads to unevenness of the spray coating. Moreover, in the process of transferring the aluminum veneer from one process to another, dust will fall on the surface of the aluminum veneer, and this dust will also affect the spraying effect.

[0005] (II) Technical solution In order to achieve the above technical purpose, the present invention provides a surface treatment device for aluminum veneer for curtain wall: It includes a processing table, on the top of which two first vertical plates are fixed.

[0010] Preferably, suction pipes are provided on the sides of the two cover bodies away from each other. A plurality of conduits are fixedly connected and communicated on the sides of the two cover bodies away from each other. The ends of the conduits away from the cover bodies are fixedly connected and communicated with the corresponding suction pipes. One ends of the two suction pipes are fixedly connected and communicated with a second connecting pipe together.

[0014] The present invention also provides a surface treatment process for aluminum single plates for curtain walls, which is applied to the surface treatment device for aluminum single plates for curtain walls described in any one of the above. The treatment process includes the following steps: Step 1: First, place the corrugated aluminum single plate into the storage grooves of the two support plates; Step 2: Rotate the bidirectional screw rod to drive the two rectangular rods to approach each other. When the rectangular rods move, they drive the cover body to move, and then drive the two cover bodies to approach the support plate. Stop rotating the bidirectional screw rod until the rollers are in contact with the support plate; Step 3: Start the servo motor to drive the threaded rod to rotate. When the threaded rod rotates, it drives the rectangular plate to move. When the rectangular plate moves, it drives the U-shaped plate to move, and then drives the cover body to move. Start the pump body to transport the paint in the paint can to the aggregate pipe through the material guiding pipe, and then spray it out from the nozzle; Step 4: When the U-shaped plate moves to the outside of the wavy aluminum veneer, the roller rolls on the surface of the wavy aluminum veneer, and as the wavy aluminum veneer fluctuates, the U-shaped plate rotates on the connecting column, and the moving plate moves up and down on the guide rod as the wavy aluminum veneer fluctuates, so that the roller is always located on the surface of the wavy aluminum veneer and rolls, so that the distance between the nozzle and the surface of the wavy aluminum veneer is constant, ensuring the uniformity of spraying; Step 5: When the roller rolls on the surface of the wavy aluminum veneer, it drives the shaft to rotate. When the shaft rotates, it drives the driving wheel to rotate. When the driving wheel rotates, it drives the driven wheel to rotate through the belt, and then drives the roller brush to rotate. When the roller brush rotates, it cleans the dust on the surface of the wavy aluminum veneer. Then start the vacuum pump and extract the air in the cover through the vacuum pipe, so that the cleaned dust is sucked into the vacuum pipe and then discharged from the exhaust pipe.

[0015] It can be seen from the above technical solutions that this application has the following beneficial effects: 1: When the U-shaped plate moves on the outside of the wavy aluminum veneer, the roller rolls on the surface of the wavy aluminum veneer, and as the wavy aluminum veneer fluctuates, the U-shaped plate rotates on the connecting column, and the moving plate moves up and down on the guide rod as the wavy aluminum veneer fluctuates, so that the roller is always on the surface of the wavy aluminum veneer and rolls, so that the distance between the nozzle and the surface of the wavy aluminum veneer is constant, ensuring the uniformity of spraying.

[0016] 2: When the roller rolls on the surface of the wavy aluminum veneer, it drives the shaft to rotate. When the shaft rotates, it drives the driving wheel to rotate. When the driving wheel rotates, it drives the driven wheel to rotate through the belt, and then drives the roller brush to rotate. When the roller brush rotates, it cleans the dust on the surface of the wavy aluminum veneer. Then start the vacuum pump and extract the air in the cover through the vacuum pipe, so that the cleaned dust is sucked into the vacuum pipe and then discharged from the exhaust pipe, avoiding dust adhering to the wavy aluminum veneer and affecting the spraying effect.

[0017] 3: When the roller, the support plate and the surface of the corrugated aluminum veneer are in contact with each other, the baffle, the support plate and the corrugated aluminum veneer have been in contact with each other in advance, and the baffle has been squeezed, so that the coil spring is in a compressed state, so that the baffle above or below the support plate can be in contact with the support plate. At this time, the baffle can block the airflow when the dust in the cover is sucked away and affect the spraying process. BRIEF DESCRIPTION OF THE DRAWINGS

The plate 3 and the outer side of the corrugated aluminum single plate 5 roll, and a connecting component is arranged on one side of the cover body 7. When the roller 10 rolls on the corrugated aluminum single plate 5, the roller brush 9 is driven to rotate through the connecting component.

[0023] Among them, a rectangular groove 40 is opened in the U-shaped plate 6, and a rectangular rod 39 is fixed on one side of the cover body 7. The rectangular rod 39 is slidably fitted in the rectangular groove 40, and both sides of the rectangular rod 39 are in contact with the inner wall of the rectangular groove 40. A bidirectional screw 41 is rotatably connected in the rectangular groove 40. The bidirectional screw 41 passes through the rectangular rod 39 and is threadedly connected to the rectangular rod 39.

When the rectangular rod 39 moves, it drives the cover body 7 to move, and then drives the two cover bodies 7 to approach the support plate 3 until the roller 10 and the support plate 3 are in contact. Then stop rotating the bidirectional screw 41. At this time, the roller 10 and the support plate 3 are in contact, but there is still a gap between the bottom of the cover body 7 and the support plate 3, so that when the roller 10 rolls on the curved part on the corrugated aluminum single plate 5, the bottom of the cover body 7 will not touch the corrugated aluminum single plate 5.

[0026] In addition, a plurality of brackets 13 are fixed on the two collecting pipes 11, one end of the bracket 13 is fixed to the cover body 7, one end of the two collecting pipes 11 is fixed together and connected with a first connecting pipe 26, and a material guide pipe 27 is fixed and connected to the first connecting pipe 26, a paint tank 29 is arranged below the processing table 1, a pump body 30 is installed on the paint tank 29, one end of the material guide pipe 27 away from the nozzle 12 is fixed and connected to the discharge port of the pump body 30, a suction pipe 31 is fixed and connected to the feed port of the pump body 30, and the suction pipe 31 extends into the paint tank 29, and a suction pipe 32 is arranged on the side of the two cover bodies 7 away from each other, and the side of the two cover bodies 7 away from each other is fixed and There are multiple ducts 33 connected, and one end of the duct 33 away from the cover body 7 is fixed and connected to the corresponding suction pipe 32, one end of the two suction pipes 32 is commonly fixed and connected to the second connecting pipe 34, and the second connecting pipe 34 is fixed with an exhaust pipe 35 and connected, and an exhaust pump 37 is installed on the paint tank 29, one end of the exhaust pipe 35 away from the second connecting pipe 34 is fixed and connected to the air inlet of the exhaust pump 37, and the air outlet of the exhaust pump 37 is fixed and connected to the exhaust pipe 38, and a first stroke groove 28 and a second stroke groove 36 are opened in the processing table 1, the guide pipe 27 is slidably fitted in the first stroke groove 28, and the exhaust pipe 35 is slidably fitted in the second stroke groove 36.

[0027] When in use, start the servo motor 22 to drive the threaded rod 19 to rotate, and when the threaded rod 19 rotates, it drives the rectangular plate 21 to move, and when the rectangular plate 21 moves, it drives the U-shaped plate 14 to move, and then drives the U-shaped plate 6 to move, and when the U-shaped plate 6 moves, it drives the cover body 7 to move, and start the pump body 30 to transport the paint in the paint tank 29 to the collecting pipe 11 through the guide pipe 27, and then spray it out from the nozzle 12, and then the spraying work can be carried out. When the U-shaped plate 6 moves to the outside of the wavy aluminum single plate 5, the roller 10 rolls on the surface of the wavy aluminum single plate 5, and with the fluctuation of the wavy aluminum single plate 5, the U-shaped plate 6 rotates on the connecting column 17, and the movable plate 16 moves up and down on the guide rod 15 with the fluctuation of the wavy aluminum single plate 5, so that the roller 10 is always located on the surface of the wavy aluminum single plate 5 and rolls, so that the distance between the nozzle 12 and the surface of the wavy aluminum single plate 5 is constant, ensuring the uniformity of the spraying.

[0028] It should be noted that the nozzle 12 and the suction pipe 32 are made of metal and do not deform, the exhaust pipe 35 and the guide pipe 27 are made of PVC (polyvinyl chloride), are soft in texture, and can be bent and deformed. When the U-shaped plate 6 moves on the wavy aluminum single plate 5, the guide pipe 27 and the exhaust pipe 35 can be deformed in the direction of movement, but the thickness of the exhaust pipe 35 and the guide pipe 27 is thick enough. When the vacuum pump 37 is pumping air, the exhaust pipe 35 will not be concave, so that the exhaust pipe 35 can smoothly extract the air in the cover body 7. In addition, a feeding pipe is fixed and connected to the paint tank 29, and a pipe cap is threadedly connected to the feeding pipe, and the servo motor 2 in this embodiment 2. The pump body 30 and the vacuum pump 37 are conventional equipment purchased on the market and known to those skilled in the art. The models can be selected or customized according to actual needs. In this technical solution, we only use them and do not improve their structure and function. For technicians in this field, their setting method, installation method and electrical connection method only need to be debugged and operated according to the requirements of their instruction manual, and will not be described in detail here. The servo motor 22, the pump body 30 and the vacuum pump 37 are all provided with matching control switches. The installation position of the control switch is selected according to actual use requirements to facilitate the operator to operate and control.

[0029] Furthermore, the connecting component includes a driving wheel 23, one end of the rotating shaft 8 extending outside the cover body 7 is fixed to the driving wheel 23, and the roller of the roller brush 9 extends to one end outside the cover body 7 and is fixed with a driven wheel 24, and the driving wheel 23 and the driven wheel 24 are driven by a belt 25.

[0030] When in use, when the roller 10 rolls on the surface of the wavy aluminum single plate 5, it drives the rotating shaft 8 to rotate, and when the rotating shaft 8 rotates, it drives the driving wheel 23 to rotate. When the driving wheel 23 rotates, it drives the driven wheel 24 to rotate through the belt 25, and then drives the roller brush 9 to rotate. When the roller brush 9 rotates, it cleans the dust on the surface of the wavy aluminum single plate 5, and then starts the vacuum pump 37 to extract the air in the cover body 7 through the vacuum pipe 35, so that the cleaned dust is sucked into the vacuum pipe 35 and then discharged from the exhaust pipe 38.

[0031] Specifically, a slot 42 is provided on one side of the cover body 7, a cylindrical rod 43 is fixed in the slot 42, a baffle 44 is rotatably connected in the slot 42, and an inner cavity 45 is provided in the baffle 44, the cylindrical rod 43 is located inside the inner cavity 45, a coil spring 46 is provided in the inner cavity 45, one side of the coil spring 46 is fixed to the cylindrical rod 43, and the other side of the coil spring 46 is fixed to the inner wall of the inner cavity 45.

[0032] It should be noted that when the coil spring 46 is in the normal state, the baffle 44 is in an inclined state, and at this time the distance from the bottom of the baffle 44 to the bottom of the cover body 7 is greater than the distance from the bottom of the roller 10 to the bottom of the cover body 7, so that in the process of bringing the cover body 7 close to the support plate 3 and the wavy aluminum single plate 5, when the roller 10 and the surfaces of the support plate 3 and the wavy aluminum single plate 5 are in contact with each other, the baffle 44 and the support plate 3 and the wavy aluminum single plate 5 have already been in contact with each other in advance, and the baffle 44 has been squeezed, so that the coil spring 46 is in a compressed state, so that the baffle 44 above or below the support plate 3 can be in contact with the support plate 3, and the baffle 44 at this time can have a blocking effect to prevent the airflow when the dust in the cover body 7 is sucked away from affecting the spraying process.

[0033] Embodiment 2 A surface treatment process of an aluminum veneer for curtain wall, based on the first embodiment, comprises the following steps: Step 1: First, place the corrugated aluminum veneer 5 into the storage slots 4 of the two support plates 3; Step 2: Rotate the bidirectional screw 41 to drive the two rectangular rods 39 to move closer to each other. When the rectangular rod 39 moves, it drives the cover 7 to move, and then drives the two cover bodies 7 to move closer to the support plate 3. After the roller 10 and the support plate 3 are in contact, stop rotating the bidirectional screw 41. Step 3: Start the servo motor 22 to drive the threaded rod 19 to rotate, and when the threaded rod 19 rotates, it drives the rectangular plate 21 to move, and when the rectangular plate 21 moves, it drives the U-shaped plate 14 to move, and then drives the U-shaped plate 6 to move, and when the U-shaped plate 6 moves, it drives the cover body 7 to move, and start the pump body 30 to transport the paint in the paint tank 29 to the collecting pipe 11 through the guide pipe 27, and then spray it out from the nozzle 12 for spraying; Step 4: When the U-shaped plate 6 moves to the outside of the corrugated aluminum veneer 5, the roller 10 rolls on the surface of the corrugated aluminum veneer 5, and as the corrugated aluminum veneer 5 fluctuates, the U-shaped plate 6 rotates on the connecting column 17, and the moving plate 16 moves up and down on the guide rod 15 as the corrugated aluminum veneer 5 fluctuates, so that the roller 10 is always located on the surface of the corrugated aluminum veneer 5 and rolls, so that the distance between the nozzle 12 and the surface of the corrugated aluminum veneer 5 is constant, ensuring the uniformity of spraying; Step five: When the roller 10 rolls on the surface of the wavy aluminum veneer 5, it drives the rotating shaft 8 to rotate. When the rotating shaft 8 rotates, it drives the driving wheel 23 to rotate. When the driving wheel 23 rotates, it drives the driven wheel 24 to rotate through the belt 25, and then drives the roller brush 9 to rotate. When the roller brush 9 rotates, it cleans the dust on the surface of the wavy aluminum veneer 5, and then starts the vacuum pump 37 to extract the air in the cover body 7 through the vacuum pipe 35, so that the cleaned dust is sucked into the vacuum pipe 35 and then discharged from the exhaust pipe 38.

[0034] The exemplary implementation scheme of the present disclosure is described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
