Description

Technical Field

[0001] This invention relates to the field of spraying equipment technology, and in particular to a steel drum spraying production line. Background Technology

[0002] The steel drums produced by the factory consist of a cylindrical body and two circular plates. To improve the service life of the steel drums, it is necessary to spray paint on the inside and outside of the drums. Currently, many factories still use manual hand-held spray guns for spraying, which is time-consuming and labor-intensive and affects the overall production efficiency. It is necessary to design a spraying production line to automate the spraying of the inner and outer walls of the steel drums, the bottom cover and the top cover. Summary of the Invention

[0003] The purpose of this invention is to provide a steel drum spraying production line that has the effects of automated spraying and improved overall production efficiency.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a material distribution device, a turning device, a diversion device, and a spraying device are sequentially arranged on a base plate. The material distribution device includes a first conveyor belt with its lower end inclined toward the turning device. A material distribution rod is provided in the middle of the conveyor belt and rotatably connected to a first supporting vertical plate on one side. The second conveyor belt of the turning device is perpendicular to the first conveyor belt. The turning device is used to turn the horizontally placed steel drum into a vertical state. A diversion device is provided at the end of the second conveyor belt away from the first conveyor belt. Spraying devices are provided on both sides of the diversion device.

[0005] By adopting the above technical solution, the material distribution device separates multiple horizontally lying steel drums one by one and brings them close to the turning device. The turning device turns the horizontally lying steel drums into a vertical state and places them on the second conveyor belt of the diversion device. The diversion device then feeds the continuously conveyed steel drums into two identical spraying devices on both sides of the diversion device. In this way, the two spraying devices can alternately complete the spraying of the steel drums, which significantly improves the spraying efficiency. The design of the entire production line realizes automated transportation and spraying, replaces manual spraying, reduces the labor force of manual operation, and significantly improves the overall production efficiency.

[0006] A further configuration of the present invention is as follows: the spraying device includes an inner spray head and an outer spray head. Several inner spray heads are arranged circumferentially around the bottom end of a first drive rod. Two outer spray heads are located at the bottom ends of two drive rods. The first and second drive rods are parallel. The top of the second drive rod is vertically fixed to opposite sides of the bottom surface of the rotating plate. The first drive rod passes through the center of the rotating plate and a limiting block in the drive assembly that drives the first drive rod to rotate. The limiting block is slidably connected to a slide rail supporting the vertical plate. The first drive rod is rotatably connected to the limiting block. A retaining ball is vertically fixed at the top end of the first drive rod. The retaining ball engages in a groove on the inner side of a fixed arc plate. The fixed arc plate is located directly above the slide rail. The groove includes a connected groove segment 1 and a groove segment 2. The groove segment 1 is a straight line located on one side of the fixed arc plate, and the groove segment 2 is an arc that gradually moves away from the groove segment 1 along the direction closer to the rotating plate.

[0007] A further configuration of the present invention is that the driving assembly further includes a first connecting rod hinged to the limiting block, the other end of the first connecting rod being hinged to a second connecting rod, and the other end of the second connecting rod being fixedly connected to the output shaft of the driving motor.

[0008] By adopting the above technical solution, when a vertical steel drum with open ends is transported into the spraying device, it stops below the first drive rod. The output motor is then started, driving the second connecting rod to rotate. This drives the first connecting rod to move the limiting block in the slide rail supporting the vertical plate. Since the first drive rod is connected to the limiting block for limiting rotation, when the limiting block slides towards the steel drum, the ball at the top of the first drive rod first slides in the first section of the slide groove, causing both the first and second drive rods to descend. At this time, both the first and second drive rods descend simultaneously. As the connecting rod 2 rotates further and the limiting block slides further down, the ball slides in the groove section 2, causing the driving rod 2 to rotate. At this time, the driving rod 1 extends into the steel drum while rotating inside. The inner nozzle is then sprayed onto the inner wall of the steel drum. Simultaneously, the rotation of the driving rod 1 drives the rotating plate to rotate, causing the driving rod 2 to also descend and rotate. The outer nozzle then sprays onto the outer wall of the steel drum. This lifting and rotating spraying process improves spraying efficiency, ensures that the inside and outside of the steel drum are sprayed, and guarantees the spraying effect.

[0009] A further configuration of the present invention is as follows: the material distribution rod is U-shaped, the material distribution rod is rotatably connected to the support vertical plate, the two horizontal bars of the material distribution rod include an upper long horizontal bar and a lower short horizontal bar, the ends of the long horizontal bar and the short horizontal bar are provided with material distribution plates, the two material distribution plates are arranged facing each other, and the bottom surface of the short horizontal bar is in contact with the cam plate.

[0010] By adopting the above technical solution, when multiple horizontally placed steel drums approach the turning device on the conveyor belt, the cam plate rotates. When its convex part rotates to lift the short horizontal bar below, the long horizontal bar rises, and the steel drums located between the two distribution plates are released and slide closer to the turning device. As the cam plate rotates again, the short horizontal bar falls, and the steel drums blocked by the short horizontal bar slide down to the distribution plate near the long horizontal bar, realizing the individual distribution of steel drums. The individual feeding and subsequent individual turning provide coordination to realize the complete production line operation.

[0011] A further configuration of the present invention is as follows: the flipping device includes two clamping cylinders disposed opposite to each other on both sides of the clamping plate; the clamping plate is fixed to one end of the clamping rod; the clamping rod is rotatably connected to the second supporting vertical plate, and the other end is slidably connected to the second sliding groove of the second supporting vertical plate; the second sliding groove includes an arc segment one and straight segments two and three connected to the two ends of the arc segment; the central angle of the circle corresponding to the arc segment one is a right angle; the straight segments two and three form acute angles with the arc segment one and are both right angles; a rotating bar is rotatably connected to the second supporting vertical plate; the rotating bar is provided with a slot hole; and the short rod at the end of the clamping rod passes through the slot hole and is slidably connected to the second sliding groove.

[0012] By adopting the above technical solution, when the horizontally placed steel drum is at one end of the conveyor belt, the clamping rod rotates. When the clamping rod rotates to the straight section three of the conveyor belt two near the diversion device in the chute two, since the straight section three is a vertical straight section, the clamping cylinder descends to clamp the horizontal steel drum on the conveyor belt. Then the clamping rod rotates further, rotating along the straight section three, the arc section one, and the straight section two. Since the straight section two is a horizontal straight section, the horizontally placed steel drum is finally flipped into a vertical state and placed on the conveyor belt two of the diversion device, preparing for subsequent spraying of the inside and outside of the steel drum. The setting of the slot on the rotating rod provides space for the clamping rod to slide in the straight section two and the straight section three.

[0013] A further configuration of the present invention is as follows: the diversion device includes limiting rods disposed on opposite sides of the second conveyor belt; a diversion arc plate is rotatably connected to the end of the second conveyor belt near the spraying device; an incomplete gear one and an incomplete gear two are fixed on both the upper and lower sides of the rotating shaft fixed to the end of the diversion arc plate; the incomplete gear one and the incomplete gear two are both externally meshed with an incomplete gear three; the incomplete gear three has two toothed portions; and the incomplete gear three is coaxially fixedly connected to the output shaft of the diversion motor.

[0014] By adopting the above technical solution, when the shunt motor rotates, when the incomplete gear three rotates clockwise, and its first toothed part meshes with the incomplete gear one, the incomplete gear one rotates counterclockwise, and the shunt arc plate rotates counterclockwise toward the spraying device on one side. Subsequently, the toothless part of the incomplete gear three rotates, and the shunt arc plate remains stationary. With further rotation, the second toothed part meshes with the incomplete gear two, and the incomplete gear two rotates clockwise, causing the shunt arc plate to return to its original position clockwise. With further rotation, the first toothed part meshes with the incomplete gear two, and the incomplete gear two rotates clockwise, causing the shunt arc plate to rotate clockwise toward the spraying device on the other side. With the incomplete gear three rotating again, the second toothed part meshes with the incomplete gear one, and the shunt arc plate rotates counterclockwise back to its original position. This achieves the goal of feeding the two steel barrels into the spraying devices on both sides respectively. The shunt device is set up to cooperate with the two spraying devices, improving the spraying efficiency.

[0015] A further configuration of the present invention is as follows: a connecting plate is provided for limiting rotational connection of the drive rod located below the rotating plate, and a pressure plate is connected to the bottom of the connecting plate by a spring. The bottom surface of the pressure plate is provided with a concave annular groove, and a through arc-shaped strip is provided around the periphery of the pressure plate. The two drive rods are slidably connected through the corresponding arc-shaped strip.

[0016] By adopting the above technical solution, when the rotating plate descends, the connecting plate descends, and the pressure plate descends. The annular groove on the bottom surface of the pressure plate first contacts the top of the steel drum and fixes it, improving the stability of the steel drum and preventing the steel drum from shaking during spraying. As the rotating plate descends further, the pressure plate remains stationary, and the spring between the pressure plate and the connecting plate is compressed, ensuring that the connecting plate descends smoothly. At the same time, the arc-shaped strip on the pressure plate can play a certain limiting role on the drive rod, ensuring the spraying effect on the outside of the steel drum.

[0017] A further configuration of the present invention is that the two outer nozzles are arranged facing each other, and the inner nozzle is arranged toward the shaft core away from the drive rod.

[0018] By adopting the above technical solution, the outer nozzle sprays the outside of the steel drum, while the inner nozzle sprays the inner wall of the steel drum.

[0019] A further provision of the present invention is that a recycling bin is provided in the support seat below the conveyor belt of each of the spraying devices.

[0020] By adopting the above technical solution, the recycling bin is set up to recover the spray liquid that flows down during the spraying process.

[0021] A further feature of the present invention is that the clamping rod is coaxially fixedly connected to the output shaft of the stepper motor.

[0022] The beneficial effects of this invention are as follows: the material distribution device separates multiple horizontally placed steel drums one by one and brings them close to the turning device. The turning device turns the horizontally placed steel drums into a vertical state and places them on the second conveyor belt of the diversion device. The diversion device then feeds the continuously conveyed steel drums into two identical spraying devices on both sides of the diversion device. In this way, the two spraying devices can alternately complete the spraying of the steel drums, which significantly improves the spraying efficiency. The design of the entire production line realizes automated transportation and spraying, replaces manual spraying, reduces the labor force of manual operation, and significantly improves the overall production efficiency.

[0033] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Example: A steel drum spraying production line, such as Figure 1-8 As shown, the device includes a material distribution device 1, a tilting device 2, a diversion device 3, and a spraying device 4, which are sequentially arranged on the base plate. The material distribution device 1 includes a conveyor belt 101 with its lower end inclined towards the tilting device 2. A material distribution rod 102 is rotatably connected to a support vertical plate 103 on one side of the conveyor belt in the middle of the conveyor belt. The conveyor belt 201 of the tilting device 2 is perpendicular to the conveyor belt 101. The tilting device 2 is used to tilt the horizontally placed steel drum to a vertical position. A diversion device 3 is provided at the end of the conveyor belt 201 away from the conveyor belt 101. Spraying devices are provided on both sides of the diversion device 3. The material distribution device 1 separates multiple horizontally lying steel drums one by one and brings them close to the turning device 2. The turning device 2 turns the horizontally lying steel drums into a vertical position and places them on the conveyor belt 201 of the diversion device 3. The diversion device 3 then feeds the continuously conveyed steel drums into two identical spraying devices 4 on both sides of the diversion device 3. In this way, the two spraying devices 4 can alternately complete the spraying of the steel drums, which significantly improves the spraying efficiency. The design of the entire production line realizes automated transportation and spraying, replaces manual spraying, reduces the labor force of manual operation, and significantly improves the overall production efficiency.

[0035] Furthermore, the spraying device 4 includes an inner spray head 401 and an outer spray head 402. Several inner spray heads 401 are arranged around the bottom circumference of the drive rod 403. Two outer spray heads 402 are located at the bottom of the drive rod 404. The drive rod 403 and drive rod 404 are parallel. The top of the drive rod 404 is vertically fixed to opposite sides of the bottom surface of the rotating plate 405. The drive rod 403 passes through the center of the rotating plate 405 and the limiting block 406 in the drive assembly that drives the drive rod 403 to rotate. The limiting block 406 is slidably connected to the slide rail 410 supporting the vertical plate. The drive rod 403 is rotatably connected to the limiting block 406. In the positioning block 406, a retaining ball 407 is vertically fixed at the top of the drive rod 403. The retaining ball 407 is engaged in the sliding groove 409 on the inner side of the fixed arc plate 408. The fixed arc plate 408 is located directly above the slide rail 410. The sliding groove 409 includes a connected groove segment 1 and groove segment 2. Groove segment 1 is a straight line located on one side of the fixed arc plate 408, and groove segment 2 is an arc that gradually moves away from groove segment 1 along the direction close to the rotating plate 405. The drive assembly also includes a connecting rod 411 hinged to the limiting block 406. The other end of connecting rod 411 is hinged to connecting rod 412, and the other end of connecting rod 412 is fixed to the output shaft of the drive motor 413. When the vertical, open-end steel drum is conveyed into the spraying device 4, it stops below drive rod 403. The output motor is then started, driving connecting rod 412 to rotate. This drives connecting rod 403 to slide in the slide rail 410 supporting the vertical plate. Since drive rod 403 is rotatably connected to the limiting block 406, when the limiting block 406 slides towards the steel drum, the ball 407 at the top of drive rod 403 first slides in the first section of the slide groove 409, causing drive rod 403 and drive rod 404 to descend. At this time, drive rod 403 and drive rod 404 move together... As the rod descends and approaches the steel drum, the connecting rod 412 rotates further, and the limiting block 406 slides further downward. At this time, the ball 407 slides in the groove section 2, that is, the driving rod 404 rotates. At this time, the driving rod 403 extends into the steel drum and rotates inside the steel drum. At this time, the inner nozzle 401 sprays the coating onto the inner wall of the steel drum. Simultaneously, the rotation of the driving rod 403 drives the rotating plate 405 to rotate, that is, the driving rod 404 also descends and rotates at the same time, so the outer nozzle 402 sprays the coating onto the outer wall of the steel drum. The lifting and rotating spraying improves the spraying efficiency, ensures that the coating of the inside and outside of the steel drum is completed, and ensures the coating effect.

[0036] Furthermore, the material distribution rod 102 is U-shaped and rotatably connected to the support vertical plate 103. The two horizontal bars of the material distribution rod 102 include an upper long horizontal bar and a lower short horizontal bar. Both the long and short horizontal bars are equipped with material distribution plates 104 at their ends. The two material distribution plates 104 are arranged facing each other. The bottom surface of the short horizontal bar is in contact with the cam plate 105. When multiple horizontally placed steel drums approach the turning device 2 on the conveyor belt 101, the cam plate 105 rotates. When its protrusion rotates to lift the lower short horizontal bar, the long horizontal bar rises. The steel drums located between the two material distribution plates 104 are released and slide close to the turning device 2. As the cam plate 105 rotates again, the short horizontal bar falls, and the steel drums blocked by the short horizontal bar slide down to the material distribution plate 104 close to the long horizontal bar, realizing the individual material distribution of the steel drums. The individual feeding and subsequent individual turning provide coordination to realize the complete production line operation.

[0037] Further, the flipping device 2 includes two clamping cylinders 202 disposed opposite to each other on both sides of the clamping plate. The clamping plate is fixed to one end of the clamping rod 203. The clamping rod 203 is coaxially fixedly connected to the output shaft of the stepper motor 11. The clamping rod 203 is rotatably connected to the second supporting vertical plate 204, and the other end is slidably connected to the second sliding groove 205 of the second supporting vertical plate 204. The second sliding groove 205 includes an arc segment 1 and straight segments 2 and 3 connected to the two ends of the arc segment. The central angle of the circle corresponding to the arc segment 1 is a right angle. The straight segments 2 and 3 form acute angles with the arc segment 1 and are both right angles. A rotating bar 206 is rotatably connected to the second supporting vertical plate 204. The rotating bar 206 is provided with a bar hole. The short rod at the end of the clamping rod 203 passes through the bar hole and is slidably connected to the second supporting vertical plate 204. In chute 205, when the horizontally placed steel drum is at the end of conveyor belt 101, the clamping rod 203 rotates. When the clamping rod 203 rotates to the straight section three of conveyor belt 201 near the diversion device 3 in chute 205, the clamping cylinder 202 descends to clamp the horizontal steel drum on conveyor belt 101 because straight section three is a vertical straight section. Then the clamping rod 203 rotates further along straight section three, arc section one, and straight section two. Because straight section two is a horizontal straight section, the horizontally placed steel drum is finally flipped into a vertical state and placed on conveyor belt 201 of diversion device 3, in preparation for subsequent spraying of the inside and outside of the steel drum. The setting of the slot on the rotating bar 206 provides space for the clamping rod 203 to slide in straight section two and straight section three.

[0038] Furthermore, the diversion device 3 includes a second conveyor belt 201 and limiting rods 301 disposed on opposite sides of the second conveyor belt 201. A diversion arc plate 302 is rotatably connected to the end of the second conveyor belt 201 near the spraying device 4. Incomplete gears 1 and 2 are fixed on both the upper and lower sides of the rotating shaft fixed to the end of the diversion arc plate 302. Both incomplete gears 1 and 2 mesh with incomplete gears 305. Incomplete gears 305 have two toothed portions. Incomplete gears 305 are coaxially fixedly connected to the output shaft of the diversion motor 306. When the diversion motor 306 rotates, when incomplete gears 305 rotate clockwise, when the first toothed portion meshes with incomplete gears 1 and 303, incomplete gears 1 and 303 rotate counterclockwise. The spraying device 4 facing one side is rotated counterclockwise. Then, the toothless part of the incomplete gear 305 rotates, and the flow-dividing arc plate 302 remains stationary. With further rotation, the second toothed part meshes with the incomplete gear 2 304. The incomplete gear 2 304 rotates clockwise, and the flow-dividing arc plate 302 returns to its original position clockwise. With further rotation, the first toothed part meshes with the incomplete gear 2 304. The incomplete gear 2 304 rotates clockwise, and the flow-dividing arc plate 302 rotates clockwise towards the spraying device 4 on the other side. With the incomplete gear 305 rotating again, the second toothed part meshes with the incomplete gear 1 303, and the flow-dividing arc plate 302 rotates counterclockwise back to its original position. This allows the two steel barrels to be fed into the spraying devices 4 on both sides respectively. The flow-dividing device 3 is set up to cooperate with the two spraying devices 4 to improve the spraying efficiency.

[0039] Furthermore, a connecting plate 5 is rotatably connected to the drive rod 403 located below the rotating plate 405. The bottom of the connecting plate 5 is connected to a pressure plate 7 via a spring 6. The bottom surface of the pressure plate 7 is provided with a concave annular groove, and a through arc-shaped strip 8 is provided around the periphery of the pressure plate 7. The two drive rods 404 are slidably connected through the corresponding arc-shaped strips 8. When the rotating plate 405 descends, the connecting plate 5 descends, and the pressure plate 7 descends. The annular groove on the bottom surface of the pressure plate 7 first contacts and fixes the top of the steel barrel, improving the stability of the steel barrel and preventing it from shaking during spraying. As the rotating plate 405 descends further, the pressure plate 7 remains stationary, and the spring 6 between the pressure plate 7 and the connecting plate 5 is compressed, ensuring that the connecting plate 5 descends smoothly. At the same time, the arc-shaped strip 8 on the pressure plate 7 can provide a certain limiting effect on the drive rod, ensuring the spraying effect on the outside of the steel barrel.

[0040] Furthermore, the two outer nozzles 402 are arranged facing each other, and the inner nozzle 401 is arranged toward the shaft core away from the drive rod 403. The outer nozzles 402 spray the outside of the steel barrel, and the inner nozzles 401 spray the inner wall of the steel barrel.

[0041] Furthermore, each spraying device 4 has a recovery box 10 installed in the support base below the conveyor belt 9. The recovery box 10 is used to recover the spraying liquid that flows down during the spraying process.

[0042] The working principle of a steel drum spraying production line:

[0043] The material distribution device 1 separates multiple horizontally lying steel drums one by one and brings them close to the turning device 2. The turning device 2 turns the horizontally lying steel drums into a vertical position and places them on the conveyor belt 201 of the diversion device 3. The diversion device 3 then feeds the continuously conveyed steel drums into two identical spraying devices 4 on both sides of the diversion device 3. In this way, the two spraying devices 4 can alternately complete the spraying of the steel drums, which significantly improves the spraying efficiency. The design of the entire production line realizes automated transportation and spraying, replaces manual spraying, reduces manual labor, and significantly improves the overall production efficiency.
