Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of surface treatment devices, in particular to a steel plate surface treatment device. BACKGROUND

[0002] Steel plate is a flat plate-shaped steel material poured and rolled from molten steel, which is a widely used basic material in industrial production. Its performance, classification and application scenarios are very rich. After the production of steel plate is completed, its surface usually needs to be treated in multiple processes, including paint spraying treatment. Because the main component of steel plate is iron, it is prone to electrochemical corrosion in the natural environment. Therefore, after painting, a continuous and dense physical barrier is formed on the surface of the steel plate, thereby blocking the occurrence of corrosion reaction.

[0003] When spraying paint on the surface of the steel plate, the surface of the steel plate can be sprayed by an automatic paint spraying device or manual paint spraying. Because both sides of the steel plate need to be painted, after painting one side of the steel plate, it usually needs to be turned over to paint the other side. When painting some small steel plates or steel plates with relatively light weight, after painting one side, the surface paint needs to be air dried and then manually turned over by the worker, and then the other side is painted. This way is more laborious, and when the worker touches the steel plate, some paint may also be attached. SUMMARY

[0004] To overcome the above-mentioned defects, embodiments of the present disclosure provide a steel plate surface treatment device to solve the technical problem that in the prior art, after painting one side of the steel plate, the worker needs to manually carry and rotate to paint the other side, which is more laborious.

[0005] According to one aspect, at least one embodiment of the present disclosure provides a steel plate surface treatment device, which comprises a treatment table, and further comprises a placing rack, a plate turning assembly, a turning box, a plate fixing assembly and a relative moving assembly. The top end of the treatment table is fixedly provided with two placing racks. The top end of the treatment table is provided with two plate turning assemblies. The turning box is provided with two turning boxes, and the two turning boxes are respectively arranged on the two plate turning assemblies. The turning box is provided with two plate fixing assemblies for fixing the steel plate in the turning box. The relative moving assembly is arranged on the side of the treatment table to drive the two turning boxes to move relative to or opposite to each other, so as to place the steel plate on the placing rack.

[0006] Furthermore, the plate flipping assembly includes a moving frame, a first electric cylinder, a support frame, and a first motor. There are two moving frames, both of which are slidably mounted on the side of the processing table. The first electric cylinder is mounted on the moving frame. The bottom end of the support frame is fixedly mounted on the output ends of the two first electric cylinders. The first motor is mounted inside the support frame, and the side of the flipping box is fixedly connected to the output end of the first motor.

[0007] Furthermore, the plate fixing assembly includes a second electric cylinder and a clamping block. Two second electric cylinders are installed on the top of the flipping box, and the clamping block is fixedly connected to the output end of the second electric cylinder.

[0008] Furthermore, the relative movement assembly includes a moving frame, a moving rack, a rotating shaft, a second motor, a rotating gear ring, a drive assembly, and a push assembly. The moving frame is slidably mounted on the side of the processing table. The moving rack is fixedly mounted on both sides of the flip box. Two rotating shafts are rotatably mounted on the moving frame. The second motor is mounted on the moving frame, and the output end of the second motor is coaxially connected to one of the rotating shafts. The rotating gear ring is fixedly mounted on both rotating shafts. The drive assembly is disposed on the moving frame, and the push assembly is disposed on the side of the processing table.

[0009] Furthermore, the drive assembly includes a drive shaft, drive gears, and drive gear rings. The drive shaft is rotatably mounted on the movable frame via a support plate. The drive gears are fixedly mounted on both sides of the drive shaft. The drive gear rings are fixedly mounted on both of the two rotating shafts, and the two drive gear rings mesh with the two drive gears respectively.

[0010] Furthermore, the pushing assembly includes a third electric cylinder and a connecting frame. Two of the third electric cylinders are mounted on the side of the processing table. One end of the connecting frame is fixedly mounted on the output end of the third electric cylinder, and the other end of the connecting frame is fixedly mounted on the side of the movable frame.

[0011] In order to enable the movable frame and the movable frame to move on the side of the processing table, a slide rail is fixedly installed on the side of the processing table, and the bottom ends of the movable frame and the movable frame are slidably installed on the slide rail.

[0012] In order to clamp the steel plate on both sides, the two flip boxes are located on the sides of the two placement racks respectively.

[0013] In order to place the steel plate into the flip box, the height of the flip box is greater than the thickness of the steel plate.

[0014] In order to enable spraying on the surface of the steel plate, a gun holder is fixedly installed on the side of the processing table, and a spray gun is placed on the gun holder.

[0015] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, when painting a steel plate, the two flip boxes are first moved in opposite directions by a relative moving component to place the steel plate on a mounting rack, and then the painting is performed. After the painting is completed, the two flip boxes are moved in opposite directions again by the relative moving component, so that a portion of both sides of the steel plate is located inside the flip boxes. Then the plate is clamped by a plate fixing component, and finally the steel plate is rotated 180° by a plate flipping component, thereby rotating it to paint the other side.

[0016] In summary, this device, through the cooperation of the placement rack, the plate flipping assembly, the flipping box, the plate fixing assembly, and the relative moving assembly, can flip a steel plate after one side has been sprayed, and then spray the other side. Compared with manual flipping, it is more labor-saving and does not require workers to touch the steel plate. Attached Figure Description

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figures 1-6 As shown, a steel plate surface treatment device according to an embodiment of the present disclosure is illustrated, including a treatment table 1, a placement rack 2, a plate flipping assembly, a flipping box 3, a plate fixing assembly, and a relative movement assembly. Two placement racks 2 are fixedly installed on the top of the treatment table 1, two plate flipping assemblies are provided on the top of the treatment table 1, and two flipping boxes 3 are provided. The two flipping boxes 3 are respectively provided on the two plate flipping assemblies, and two plate fixing assemblies are provided on the flipping boxes 3 for fixing the steel plate inside the flipping boxes 3. The relative movement assembly is provided on the side of the treatment table 1 for driving the two flipping boxes 3 to move relative to or in opposite directions, thereby placing the steel plate on the placement rack 2.

[0027] like Figure 5 As shown, when spraying the steel plate, the steel plate is first placed on the placement rack 2. Because the side of the processing table 1 is fixedly installed with a gun holder 21, and a spray gun 22 is placed on the gun holder 21, the worker holds the spray gun 22 to spray one side of the steel plate. After the spraying is completed, it is air-dried for a period of time until the paint on the surface of the steel plate is dry.

[0028] like Figure 2 and Figure 6As shown, after air drying, the two flip boxes 3 are moved relative to each other by a relative moving component. The relative moving component includes a moving frame 10, a moving rack 11, a rotating shaft 12, a second motor 13, a rotating gear ring 14, a drive component, and a push component. The moving frame 10 is slidably mounted on the side of the processing table 1. Moving racks 11 are fixedly mounted on both sides of the flip boxes 3. Two rotating shafts 12 are rotatably mounted on the moving frame 10. The second motor 13 is mounted on the moving frame 10, and the output end of the second motor 13 is coaxially connected to one of the rotating shafts 12. Rotating gear rings 14 are fixedly mounted on both rotating shafts 12. The drive component is located on the moving frame 10 and pushes... The drive assembly is located on the side of the processing table 1. The drive assembly includes a drive shaft 15, a drive gear 16, and a drive gear ring 17. The drive shaft 15 is rotatably mounted on the movable frame 10 via a support plate. Drive gears 16 are fixedly mounted on both sides of the drive shaft 15. Drive gear rings 17 are fixedly mounted on both rotating shafts 12, and the two drive gear rings 17 mesh with the two drive gears 16 respectively. The push assembly includes a second electric cylinder 8 and a connecting frame 19. Two second electric cylinders 8 are mounted on the side of the processing table 1. One end of the connecting frame 19 is fixedly mounted on the output end of the second electric cylinder 8, and the other end of the connecting frame 19 is fixedly mounted on the side of the movable frame 10.

[0029] Specifically, since the two flip boxes 3 are located on the sides of the two placement racks 2 respectively, the second motor 13 is started. The output end of the second motor 13 drives one of the rotating shafts 12 to rotate. The rotating shaft 12 drives the rotating gear ring 14 and the drive gear ring 17 to rotate synchronously. At this time, the rotating gear ring 14 meshes with the moving rack 11 on the side of the flip box 3. The rotating gear ring 14 then drives the moving rack 11 to move. The moving rack 11 then drives the flip box 3 to move forward. Under the movement of the moving frame 4, the flip box 3 can move forward. At the same time, the rotating shaft 12 drives one of the drive gear rings 17 to rotate. The drive gear ring 17 drives one of the drive gear rings 17 to rotate. When gear 16 rotates, the drive gear 16 drives the drive shaft 15 to rotate, which in turn causes the drive gear ring 17 and the drive gear 16 at the other end to rotate. Another drive gear ring 17 drives another rotating shaft 12 to rotate, which in turn drives another rotating gear ring 14 to rotate, thereby causing the moving rack 11 that meshes with it to move, which in turn causes another flip box 3 to move forward. Because the height of the flip box 3 is higher than the thickness of the steel plate, the two flip boxes 3 move forward until their inner bottom ends contact the bottom end of the steel plate, and a portion of both ends of the steel plate are located inside the flip box 3. It should be added that when the steel plate is placed on the placement rack 2, the bottom end of the steel plate and the inner top end of the flip box 3 are at the same horizontal position.

[0030] like Figure 3As shown, after the movement is completed, the top of the steel plate is clamped by the plate fixing assembly. The plate fixing assembly consists of a third electric cylinder 18 and a clamping block 9. Two third electric cylinders 18 are installed on the top of the flip box 3. The clamping block 9 is fixedly connected to the output end of the third electric cylinder 18. Specifically, when the third electric cylinder 18 is started, the output end of the third electric cylinder 18 drives the clamping block 9 to move down, thereby clamping the top of the steel plate.

[0031] After clamping is completed, the second electric cylinder 8 is activated. The output end of the second electric cylinder 8 drives the connecting frame 19 to move forward. The connecting frame 19 drives the moving frame 10 to move forward. Since the side of the processing table 1 is fixedly installed with the slide rail 20, and the bottom ends of the moving frame 10 and the moving frame 4 are slidably installed on the slide rail 20, the moving frame 10 can slide forward, thereby separating the rotating gear ring 14 from the moving rack 11 so as not to affect the subsequent steel plate flipping.

[0032] like Figure 4 As shown, after the movement is completed, the steel plate is flipped by the plate flipping assembly. The plate flipping assembly includes a moving frame 4, a first electric cylinder 5, a support frame 6 and a first motor 7. There are two moving frames 4, and both moving frames 4 are slidably installed on the side of the processing table 1. The first electric cylinder 5 is installed on the moving frame 4. The bottom end of the support frame 6 is fixedly installed on the output end of the two first electric cylinders 5. The first motor 7 is installed in the support frame 6, and the side of the flipping box 3 is fixedly connected to the output end of the first motor 7.

[0033] Specifically, the first electric cylinder 5 is activated, and its output end drives the support frame 6 and the first motor 7 to move upward, thereby moving the steel plate upward. When the plate is able to be flipped, the first motor 7 is activated, and its output end drives the two flipping boxes 3 to rotate 180°, thus flipping the steel plate. The plate is then moved downward and placed on the placement rack 2. The second electric cylinder 8 is activated, which drives the moving frame 10 to move towards the position of the steel plate. The rotating gear ring 14 then meshes with the moving rack 11 at the other end of the flipping box 3. The second motor 13 is activated, which causes the two flipping boxes 3 to move in opposite directions again, placing the steel plate on the placement rack 2 and exposing it completely. Finally, the surface of the plate is sprayed with paint again.

[0034] Working principle: When spraying paint on the steel plate, the steel plate is first placed on the placement rack 2. A gun holder 21 is fixedly installed on the side of the processing table 1, and a spray gun 22 is placed on the gun holder 21. The worker holds the spray gun 22 and sprays one side of the steel plate. After spraying, it is allowed to air dry for a period of time until the paint on the steel plate surface is dry. Then, the second motor 13 is started. The output end of the second motor 13 drives one of the rotating shafts 12 to rotate. One of the rotating shafts 12 drives the rotating gear ring 14 and the drive gear ring 17 to rotate synchronously. At this time, the rotating gear ring 14 meshes with the moving rack 11 on the side of the flip box 3, and the rotating gear ring 14 drives the moving rack 11 to move. The moving rack 11 drives the flip box 3 to move forward, and the moving frame 4 also moves the flip box 3 forward. At the same time, the rotating shaft 12 drives one of the drive gear rings 17 to rotate, the drive gear ring 17 drives one of the drive gears 16 to rotate, the drive gear 16 drives the drive shaft 15 to rotate, which in turn causes the other drive gear ring 17 and drive gear 16 to rotate. The other drive gear ring 17 drives the other rotating shaft 12 to rotate, which in turn drives the other rotating gear ring 14 to rotate, thereby driving the moving rack 11 that meshes with it to move, which in turn causes the other flip box 3 to move forward. Then the two flip boxes 3 move forward until their inner bottom ends contact the bottom end of the steel plate, and a portion of both ends of the steel plate are located inside the flip box 3.

[0035] After the movement is complete, the second electric cylinder 8 is activated. The output end of the second electric cylinder 8 drives the clamping block 9 to move downward, thereby clamping the top of the steel plate. After clamping, the third electric cylinder 18 is activated. The output end of the third electric cylinder 18 drives the connecting frame 19 to move forward. The connecting frame 19 drives the moving frame 10 to move forward, thereby separating the rotating gear ring 14 from the moving rack 11 so as not to affect the subsequent steel plate flipping. Finally, the first electric cylinder 5 is activated. The output end of the first electric cylinder 5 drives the support frame 6 and the first motor 7 to move upward, thereby driving the steel plate to move upward. When the steel plate is moved up to the point where it can be flipped, the first motor 7 is started. The output end of the first motor 7 drives the two flipping boxes 3 to rotate 180°, thereby flipping the steel plate. Then it is moved down and placed on the placement rack 2. Then the second electric cylinder 8 is started, which drives the moving frame 10 to move to the position of the steel plate. Then the rotating gear ring 14 is engaged with the moving rack 11 at the other end of the flipping box 3. Then the second motor 13 is started, which makes the two flipping boxes 3 move in opposite directions again, placing the steel plate on the placement rack 2 and exposing it completely. Finally, paint is sprayed on its surface again.

[0036] It should be added that the output ends of the first motor 7 and the second motor 13 can be self-locked, and the two first motors 7 are synchronously controlled by the controller, so that when controlling the two flip boxes 3 to rotate, the direction and speed can be consistent. The two third electric cylinders 18 and the two second electric cylinders 8 are also controlled by the controller, so that they can be synchronous when the output ends extend or retract. Furthermore, the protective cover can be detachably installed on the moving frame 10 by bolts, and the drive gear 16 and the drive gear ring 17 are placed inside to protect their meshing.

[0037] It should also be added that when the rotating gear ring 14 moves in the direction of the moving gear rack 11, it can mesh with the moving gear rack 11 after the rotating gear ring 14 and the moving gear rack 11 are in contact.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
