Description

Technical Field

[0001] This utility model relates to the field of spraying machine technology, and in particular to a spraying device for improving the uniformity and density of coatings. Background Technology

[0002] A coating spraying machine is a specialized coating equipment that uses spraying technology. During operation, the airflow is controlled to drive the air distribution and reversing device, causing the pneumatic motor piston to make a stable and continuous reciprocating motion. This pressurizes the inhaled paint, which is then delivered to the spray gun through a high-pressure hose. The paint is instantly atomized and sprayed onto the surface of the object being coated. It mainly consists of a feeding device, a spray gun, and an atomization source. This equipment has many advantages, including enhanced paint film adhesion, extended coating life, ensuring uniform paint film thickness, and improved paint utilization. It can spray high-viscosity paints and easily reaches corners and gaps. It is widely used in many industries such as leather goods and handbags, gift packaging, furniture, footwear, and automobile manufacturing.

[0003] However, when coating spraying machines spray cylindrical objects, the coating thickness varies across different parts of the cylindrical surface, especially at the junction of the sides and ends. In addition, due to the special structure of the cylinder, frequent manual or mechanical flipping is required to ensure full coverage. This not only increases the number of operation steps and labor costs, but also causes coating overlap or missed spraying due to positioning deviations during the flipping process, thus reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the coating spraying machine when spraying cylindrical objects. Specifically, the coating thickness is inconsistent on different parts of the cylindrical object surface, especially at the junction of the side and end faces. In addition, due to the special structure of the cylinder, frequent manual or mechanical flipping is required to ensure full coverage. This not only increases the operation steps and labor costs, but also causes coating overlap or missed spraying due to positioning deviations during the flipping process, reducing production efficiency. Therefore, this invention proposes a spraying device to improve the uniformity and density of the coating.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a spraying device for improving the uniformity and density of coatings, comprising a body, a robotic arm, a spray head, a support platform, and a rotating device. The robotic arm is fixedly connected to the body, and a spray head is fixedly connected to one end of the robotic arm. The support platform is fixed to one end of the body, and the rotating device is disposed on the surface of the support platform. The rotating device includes a worktable, which is fixedly connected to the support platform. A mounting bracket is fixedly connected to the upper surface of the worktable, and a roller is rotatably connected to the surface of the mounting bracket. A threaded hole is formed on the surface of the roller, and a lead screw is threaded into the inner wall of the threaded hole. A motor is fixedly connected to the lower surface of the worktable, and a wheel is fixedly connected to the drive end of the motor. By setting up the rotating device, in conjunction with the motor drive belt and the roller, the workpiece is rotated at a uniform speed. This allows all areas of the workpiece surface to contact the paint evenly during the painting process, effectively reducing the problems of uneven spraying and thickness differences at the junction of the sides and ends. It eliminates the need for frequent flipping, reducing operation steps and labor costs, while also reducing positioning deviations, coating overlaps, or missed spraying caused by flipping.

[0006] Preferably, a belt is fitted onto the surface of the wheel, and the end of the belt away from the wheel is fitted onto the reel. By setting the belt, the power of the motor is transmitted in the rotating device. After the motor starts, it will drive the belt to move, and the moving belt will drive the reel to rotate. In turn, the reel will drive the cylindrical workpiece clamped and fixed by the lead screws on both sides to rotate synchronously and uniformly, so that the surface of the workpiece can be evenly contacted with the paint during the painting process.

[0007] Preferably, there are two lead screws arranged symmetrically. By rotating the two lead screws, the distance between their ends and the workpiece can be adjusted, thereby firmly clamping cylindrical workpieces of different sizes in the middle of the mounting bracket. This prevents the workpiece from shifting or shaking during the rotation driven by the motor belt and the roller, ensuring that the workpiece can rotate at a uniform speed to guarantee the uniformity of the spraying.

[0008] Preferably, a recycling component is provided at one end of the workbench. The recycling component includes a rectangular rod, which is fixedly connected to the workbench. An arc-shaped groove is provided at one end of the workbench, and a clamping plate is slidably connected to the inner wall of the arc-shaped groove at one end of the workbench. An arc-shaped box is provided on the surface of the workbench, and a slope is provided on the surface of the workbench. By setting up the recycling component, paint waste and workbench contamination are reduced, and material costs are lowered. Pulling the clamping plate allows the arc-shaped box to be pulled out and removed, facilitating subsequent processing of the recycled paint. After the insertion rod is inserted into the arc-shaped box, the spring force can compress the clamping plate and the arc-shaped box to hold the arc-shaped box firmly on the workbench, ensuring that the arc-shaped box will not shift during the recycling process and ensuring stable recycling results.

[0009] Preferably, a fixing rod is fixedly connected to one end of the workbench, and an insertion rod is fixedly connected to one end of the fixing rod. A round hole is opened at one end of the arc-shaped box, and the insertion rod is inserted into the round hole at one end of the arc-shaped box.

[0010] Preferably, a rectangular rod is fixedly connected to one end of the workbench, and the arc-shaped box is arranged in an arc shape.

[0011] Preferably, a spring is fixedly connected to one end of the clamping plate, and the end of the spring away from the clamping plate is fixedly connected to a rectangular rod. By setting the spring, when the clamping plate is released, the spring loses its restraint and generates elastic force. The elastic force squeezes the clamping plate, so that the clamping plate and the arc-shaped box are tightly pressed together, thereby firmly clamping the arc-shaped box on the worktable and preventing the arc-shaped box from shifting due to external force or paint flow during the process of recycling excess paint.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting a rotating device, the workpiece is placed in the middle of the mounting bracket during painting, and then the cylinder is clamped by the lead screws on both sides. Then the motor is started, the motor drives the belt, the belt drives the roller to rotate, and the roller rotates the workpiece together. During the rotation, the workpiece surface is sprayed with paint, which makes it easier to spray the coating evenly on the workpiece. After the painting is completed, the lead screw is rotated to release the fixation. By setting a rotating device, in conjunction with the motor driving the belt and the roller to drive the workpiece to rotate at a constant speed, the paint can be evenly contacted in all areas of the workpiece surface during the painting process, which effectively reduces the problems of uneven spraying and thickness difference at the junction of the side and end faces. There is no need to frequently flip the workpiece, which reduces operation steps and labor costs, and at the same time reduces the positioning deviation, coating overlap or missed spraying caused by flipping.

[0014] 2. In this utility model, by setting up a recycling component, when painting the workpiece, excess paint accumulates on the worktable. The paint that has not yet solidified flows into the arc-shaped box under the guidance of the ramp and is recycled by the arc-shaped box. Pulling the clamping plate releases the arc-shaped box, allowing it to be pulled out and removed. When the inserting rod is inserted into the arc-shaped box, the clamping plate is released, and the spring, freed from its restraint, generates elastic force that presses the clamping plate against the arc-shaped box, clamping the arc-shaped box onto the worktable and completing the fixation. By setting up the recycling component, paint waste and worktable contamination are reduced, material costs are lowered, and the arc-shaped box can be pulled out and removed by pulling the clamping plate, facilitating subsequent processing of the recycled paint. When the inserting rod is inserted into the arc-shaped box, the spring force can press the clamping plate against the arc-shaped box, firmly clamping the arc-shaped box onto the worktable, ensuring that the arc-shaped box will not shift during the recycling process and guaranteeing a stable recycling effect.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a spraying device for improving the uniformity and density of coatings, including a body 1, a robotic arm 2, a nozzle 3, a support platform 4 and a rotating device 5. The robotic arm 2 is fixedly connected to the body 1, and a nozzle 3 is fixedly connected to one end of the robotic arm 2. The support platform 4 is fixed to one end of the body 1, and the rotating device 5 is disposed on the surface of the support platform 4.

[0022] In this implementation scheme: the rotating device 5 includes a worktable 58, which is fixedly connected to the support platform 4. A mounting bracket 51 is fixedly connected to the upper surface of the worktable 58. A roller 53 is rotatably connected to the surface of the mounting bracket 51. A threaded hole is opened on the surface of the roller 53. A lead screw 52 is threadedly connected to the inner wall of the threaded hole of the roller 53. A motor 57 is fixedly connected to the lower surface of the worktable 58. A wheel 55 is fixedly connected to the drive end of the motor 57. By setting up the rotating device 5, the motor 57 drives the belt 54 and the roller 53 to drive the workpiece to rotate at a uniform speed. This allows the paint to be evenly applied to all areas of the workpiece surface during the painting process, effectively reducing the problems of uneven spraying and thickness differences at the junction of the side and end faces. It eliminates the need for frequent flipping, reducing operation steps and labor costs. It also reduces positioning deviations, coating overlaps, or missed spraying caused by flipping.

[0023] Preferably, a belt 54 is fitted onto the surface of the wheel 55. The end of the belt 54 away from the wheel 55 is fitted onto the reel 53. By setting the belt 54, the power of the motor 57 is transmitted in the rotating device 5. After the motor 57 starts, it will drive the belt 54 to move. The moving belt 54 will then drive the reel 53 to rotate. In turn, the reel 53 will drive the cylindrical workpiece clamped and fixed by the lead screws 52 on both sides to rotate synchronously and uniformly, so that the surface of the workpiece can be evenly contacted with the paint during the painting process.

[0024] Preferably, there are two lead screws 52, which are symmetrically arranged. By rotating the two lead screws 52, the distance between their ends and the workpiece can be adjusted, thereby firmly clamping cylindrical workpieces of different sizes in the middle of the mounting bracket 51. This prevents the workpiece from shifting or shaking during the rotation driven by the motor 57, belt 54, and roller 53, and ensures that the workpiece can rotate at a uniform speed to guarantee the uniformity of the spraying.

[0025] Preferably, a recycling component 56 is provided at one end of the workbench 58. The recycling component 56 includes a rectangular rod 565, which is fixedly connected to the workbench 58. An arc-shaped groove is provided at one end of the workbench 58, and a clamping plate 563 is slidably connected to the inner wall of the arc-shaped groove at one end of the workbench 58. An arc-shaped box 562 is provided on the surface of the workbench 58, and a ramp 561 is provided on the surface of the workbench 58. By setting up the recycling component 56, paint waste and workbench 58 contamination are reduced, and material costs are lowered. Pulling the clamping plate 563 allows the arc-shaped box 562 to be pulled out and removed, facilitating subsequent processing of the recycled paint. After the insertion rod 567 is inserted into the arc-shaped box 562, the elastic force of the spring 564 can compress the clamping plate 563 and the arc-shaped box 562 to abut against each other, firmly clamping the arc-shaped box 562 on the workbench 58, ensuring that the arc-shaped box 562 will not shift during the recycling process, and ensuring stable recycling results.

[0026] Preferably, a fixing rod 566 is fixedly connected to one end of the workbench 58, and an insertion rod 567 is fixedly connected to one end of the fixing rod 566. A round hole is opened at one end of the arc-shaped box 562, and the insertion rod 567 is inserted into the round hole at one end of the arc-shaped box 562.

[0027] Preferably, a rectangular rod 565 is fixedly connected to one end of the workbench 58, and the arc-shaped box 562 is arranged in an arc shape.

[0028] Preferably, a spring 564 is fixedly connected to one end of the card plate 563, and the end of the spring 564 away from the card plate 563 is fixedly connected to the rectangular rod 565.

[0029] In this embodiment: by setting a spring 564, when the clamping plate 563 is released, the spring 564 loses its restraint and generates elastic force. The elastic force squeezes the clamping plate 563, so that the clamping plate 563 and the arc-shaped box 562 are tightly pressed together, thereby firmly clamping the arc-shaped box 562 on the worktable 58, and preventing the arc-shaped box 562 from shifting due to external force or paint flow during the process of recycling excess paint.

[0030] Working principle: By setting up a rotating device 5, the workpiece is placed in the middle of the mounting bracket 51 during painting. Then, the cylinder is clamped by the lead screws 52 on both sides. Then, the motor 57 is started, and the motor 57 drives the belt 54. The belt 54 drives the roller 53 to rotate. The roller 53 rotates and the workpiece rotates together. During the rotation, the workpiece surface is sprayed with paint, which makes it easy to spray the coating evenly on the workpiece. After the painting is completed, the lead screw 52 is rotated to release the fixation. By setting up a rotating device 5, in conjunction with the motor 57 driving the belt 54 and the roller 53 to drive the workpiece to rotate at a constant speed, the paint can be evenly contacted in all areas of the workpiece surface during the painting process. This effectively reduces the problems of uneven spraying and thickness difference at the junction of the side and end faces. There is no need to flip the workpiece frequently, which reduces operation steps and labor costs. At the same time, it also reduces positioning deviation, coating overlap or missed spraying caused by flipping.

[0031] By setting up the recycling component 56, when painting the workpiece, excess paint accumulates on the worktable 58. Paint that hasn't yet solidified flows into the curved box 562 under the guidance of the ramp 561, where it is recycled. Pulling the clamping plate 563 releases it from the curved box 562, allowing the box to be removed. When the insertion rod 567 is inserted into the curved box 562, releasing the clamping plate 563 causes the spring 564 to lose its restraint, generating elastic force that presses the clamping plate 563 against the curved box 562, clamping the box 562. Hold it on the workbench 58 to complete the fixation. By setting up the recycling component 56, paint waste and workbench 58 pollution are reduced, and material costs are lowered. Pulling the clamping plate 563 allows the arc-shaped box 562 to be pulled out and removed, facilitating subsequent processing of the recycled paint. After the insertion rod 567 is inserted into the arc-shaped box 562, the elastic force of the spring 564 can squeeze the clamping plate 563 against the arc-shaped box 562, firmly clamping the arc-shaped box 562 on the workbench 58, ensuring that the arc-shaped box 562 will not shift during the recycling process, and ensuring stable recycling results.
