Description

Technical Field

[0001] This utility model belongs to the field of sheet metal spraying technology, and in particular relates to a spraying device for composite sheets. Background Technology

[0002] In modern industrial production, composite panels have been widely used in many fields such as construction, furniture, and automobile manufacturing due to their excellent comprehensive performance. As the market demand for composite panels continues to rise, the requirements for their surface treatment quality are becoming more and more stringent. As a key link in the surface treatment of composite panels, the spraying process can give the panels a beautiful appearance, good protective performance and specific functional characteristics. Therefore, a spraying device for composite panels is needed to spray the panels efficiently.

[0003] However, existing composite panel spraying equipment is not convenient for fixing the composite panels during spraying. The panels may shake or shift during the spraying process, resulting in uneven coating of the paint and local coatings that are too thick or too thin, thus affecting the appearance quality and overall performance of the panels. Utility Model Content

[0004] The purpose of this utility model is to provide a spraying device for composite panels. By setting up a clamping mechanism, it solves the problem that existing composite panel spraying devices are not easy to fix during spraying, and the panels may shake or shift during the spraying process, resulting in uneven coating of the paint and local coatings that are too thick or too thin, thus affecting the appearance quality and overall performance of the panels.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a spraying device for composite panels, including a support frame, on which a clamping mechanism and a flipping mechanism are provided;

[0007] The top of the support frame is fixedly connected to an annular block 1. The clamping mechanism includes an annular block 2 disposed within the annular block 1. A rotating shaft 1 is rotatably connected to the left side of the annular block 2. The right side of the rotating shaft 1 extends into the annular block 2. A hinge rod 1 is fixedly connected to the right extension of the rotating shaft 1. Two hinge rods 2 are hingedly disposed on the right side of the hinge rod 1. The flipping mechanism includes rotating shafts 3 fixedly connected to the left and right sides of the annular block 1, respectively. The two rotating shafts 3 extend into the annular block 1 on the side closest to each other. The left extension of the rotating shaft 3 on the right side is fixedly connected to the annular block 2.

[0008] Furthermore, each of the two hinge rods has a pivot shaft passing through it, and the two pivot shafts are rotatably connected to the two hinge rods. The right side of each of the two pivot shafts is fixedly connected to a clamping plate. A rectangular groove is provided on the inner wall of the right side of the annular block. Two sliders are slidably connected to the inner wall of the rectangular groove. The left side of each slider is fixedly connected to the two clamping plates. A composite plate is provided between the two clamping plates.

[0009] Furthermore, a motor housing is fixedly connected to the left side of the second annular block, the left side of the motor housing is fixedly connected to the third rotating shaft located on the left side, a motor is fixedly connected to the inner wall of the motor housing, and the output shaft of the motor is fixedly connected to the first rotating shaft through a coupling.

[0010] Furthermore, a U-shaped frame is fixedly connected to the top of the annular block, a pipe runs through the U-shaped frame, a valve is provided on the outer wall of the pipe, and a nozzle is connected to the bottom of the pipe.

[0011] Furthermore, a ring 1 is fixedly connected to the outer wall of the rotating shaft 3 on the right side, and a ring 2 is rotatably connected to the outer wall of the ring 1. The left side of the ring 2 is fixedly connected to the annular block 1.

[0012] Furthermore, two cylindrical grooves are formed on the outer wall of the ring, and spring telescopic rods are fixedly connected to the side of the two cylindrical grooves that are close to each other.

[0013] Furthermore, a hemispherical limiting block is fixedly connected to each of the two spring telescopic rods on the side away from each other, and two limiting grooves are opened on the inner wall of the second ring, which are adapted to the two hemispherical limiting blocks.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a clamping mechanism, the composite board to be processed is placed between two clamping plates. Then, the motor inside the motor housing is turned on. The motor drives the hinge rod to rotate around the hinge rod through the first rotating shaft. The hinge rod drives the two hinge rods to rotate around their hinge axes with the first hinge rod and move closer to each other. This causes the two rotating shafts on them to move closer to each other. The two clamping plates are stably moved closer to each other by the two sliders limited by the rectangular slide groove. The two rotating shafts drive the two clamping plates to move closer to each other until the composite board is clamped. Then, the motor is stopped. Then, the valve on the pipeline is opened, and the paint is sprayed onto the composite board on the clamping mechanism through the nozzle below the U-shaped frame. Then, the valve is closed to further apply the paint to the composite board, so that the composite board can be fixed during spraying. After the spraying is completed, the motor is reversed to drive the two clamping plates to release the composite board, thereby removing the composite board. This ensures that it will not shake or shift during the spraying process, so as to avoid the paint not being evenly adhered to the board, resulting in local coatings that are too thick or too thin, which would affect the appearance quality and overall performance of the board.

[0016] 2. By setting up a flipping mechanism, after one side is coated, the knob on the left rotating shaft three is turned. The left rotating shaft three drives the right rotating shaft three to rotate through the ring block two. The right rotating shaft three drives the ring one to rotate within the ring two. The two hemispherical limiting blocks are squeezed by the ring two and move closer to each other, thereby squeezing the two spring telescopic rods and causing them to retract. After the two hemispherical limiting blocks are completely retracted into the two cylindrical grooves, the ring one continues to rotate until the two cylindrical grooves slide to the vicinity of the corresponding rectangular grooves. As the ring one rotates, the two spring telescopic rods rebound and respectively drive the hemispherical limiting blocks to reset and lock in the corresponding limiting grooves. At this time, the rotation of the rotating shaft three stops, and the clamping mechanism completes the flipping, thus completing the flipping of the composite board. The coating of the other side can then begin. This allows both sides of the board to be in the appropriate coating positions in sequence, thereby realizing continuous coating of the composite board, reducing manual operation, saving labor and time costs, and improving production efficiency.

[0027] Please see Figure 1-5As shown, this utility model is a spraying device for composite panels, including a support frame 1. The support frame 1 is equipped with a clamping mechanism 2 and a flipping mechanism 3. An annular block 111 is fixedly connected to the top of the support frame 1. The clamping mechanism 2 includes an annular block 211 disposed inside the annular block 111. A rotating shaft 212 is rotatably connected to the left side of the annular block 211. The right side of the rotating shaft 212 extends into the annular block 211. A fixed connection is made to the right extension of the rotating shaft 212. There is a hinge rod 213. Two hinge rods 214 are hinged to the right side of the hinge rod 213. A pivot 215 passes through each of the two hinge rods 214, and the two pivots 215 are rotatably connected to the two hinge rods 214 respectively. A clamping plate 216 is fixedly connected to the right side of each pivot 215. A composite plate 219 is placed between the two clamping plates 216. A rectangular groove 217 is formed on the inner right side of the annular block 211, allowing for sliding along the inner wall of the rectangular groove 217. Two sliders 218 are connected, and the left sides of the two sliders 218 are fixedly connected to two clamping plates 216 respectively. The left side of the second annular block 211 is fixedly connected to a motor housing 2110. The left side of the motor housing 2110 is fixedly connected to a rotating shaft 311 located on the left side. The inner wall of the motor housing 2110 is fixedly connected to a motor 2111. The output shaft of the motor 2111 is fixedly connected to a rotating shaft 212 via a coupling. The top of the first annular block 111 is fixedly connected to a U-shaped frame 112. A pipe 113 passes through the U-shaped frame 112. A valve 114 is provided on the outer wall of the pipe 113. A nozzle 115 is connected to the bottom of the pipe 113. By setting up the clamping mechanism 2, the composite board 219 can be fixed during spraying, thereby ensuring that it will not shake or shift during the spraying process, so as to avoid the paint not being evenly adhered to the board, resulting in local coatings that are too thick or too thin, thus affecting the appearance quality and overall performance of the board.

[0028] The flipping mechanism 3 includes two rotating shafts 311 fixedly connected to the left and right sides of the annular block 111. The two rotating shafts 311 extend into the annular block 111 on their closest sides. The left extension of the right-side rotating shaft 311 is fixedly connected to the annular block 211. A circular ring 312 is fixedly connected to the outer wall of the right-side rotating shaft 311. A circular ring 313 is rotatably connected to the outer wall of the circular ring 312. The left side of the circular ring 313 is fixedly connected to the annular block 111. Two cylindrical grooves 314 are formed on the outer wall of the circular ring 312. Spring telescopic rods 315 are fixedly connected to the sides of the column grooves 314 that are close to each other, and hemispherical limiting blocks 316 are fixedly connected to the sides of the two spring telescopic rods 315 that are far from each other. Two limiting grooves 317 are opened on the inner wall of the ring 313. The two limiting grooves 317 are adapted to the two hemispherical limiting blocks 316. By setting the flipping mechanism 3, the two sides of the board can be placed in the appropriate spraying position in sequence, thereby realizing the continuous spraying operation of the composite board, reducing the manual operation links, saving labor and time costs, and improving production efficiency.

[0029] A specific application of this embodiment is as follows: In use, the composite board 219 to be processed is first placed between two clamping plates 216. Then, the motor 2111 inside the motor housing 2110 is opened. The motor 2111 drives the hinge rod 213 to rotate around the hinge rod 212 via the first rotating shaft 212. The first hinge rod 213 drives the two second hinge rods 214 to rotate around their hinge axes with the first hinge rod 213 and move closer to each other, thereby driving the two second rotating shafts 215 on them to move closer to each other. The two clamping plates 216 are then separated. The two sliders 218 are stably brought closer together under the limitation of the rectangular slide groove 217. The two rotating shafts 215 drive the two clamping plates 216 to move closer together until the composite board 219 is clamped. Then the motor 2111 is stopped, and the valve 114 on the pipe 113 is opened. The paint is then sprayed onto the composite board 219 on the clamping mechanism 2 by the nozzle 115 below the U-shaped frame 112. Then the valve 114 is closed, and the paint on the composite board 219 is further applied. After the spraying is completed, the paint is then applied to the composite board 219. The knob on the left rotating shaft 311 rotates the left rotating shaft 311. The left rotating shaft 311 drives the right rotating shaft 311 to rotate through the annular block 211. The right rotating shaft 311 drives the first ring 312 to rotate within the second ring 313. The two hemispherical limiting blocks 316 are squeezed by the second ring 313 and move closer to each other, thereby squeezing the two spring telescopic rods 315 and causing them to retract. After the two hemispherical limiting blocks 316 are completely retracted into the two cylindrical grooves 314, the first ring 312 continues to rotate until... The two cylindrical grooves 314 slide to the vicinity of the corresponding rectangular grooves 217. As the first ring 312 rotates, the two spring telescopic rods 315 rebound and respectively drive the hemispherical limit block 316 to reset and lock in the corresponding limit groove 317. At this time, the rotating shaft 311 stops rotating, the clamping mechanism 2 completes the flipping, and the composite board 219 completes the flipping, so that the spraying of the other side can begin. After the spraying is completed, the control motor 2111 reverses to drive the two clamping plates 216 to release the composite board 219, thereby removing the composite board 219.
