Description

Technical Field

[0001] This invention belongs to the technical field of automated equipment, and particularly relates to a spraying device. Background Technology

[0002] An automatic spraying device is used to automatically spray a protective or decorative coating onto the surface of a product. Since everyday products are often covered with these coatings, spraying devices are frequently found on product production lines.

[0003] In existing automated spraying equipment, due to the different uses of the products, some areas of the product may not require coating. Therefore, in current product manufacturing, coating is mainly achieved by wrapping the uncoated areas with waste paper or placing baffles above these areas to prevent paint from being sprayed onto them. However, using waste paper to prevent paint from being sprayed onto uncoated areas requires removing the paper after spraying, resulting in low production efficiency and high manpower or equipment resource consumption. Using baffles to prevent paint from being sprayed onto uncoated areas can lead to paint accumulation on the baffles during spraying. When the paint accumulates to a certain amount, it drips onto the product, affecting its quality and performance. Summary of the Invention

[0004] The purpose of this invention is to provide a spraying device to solve the technical problems described in the background art.

[0005] The spraying device includes a frame, on which clamps for holding both ends of a product are mounted. A spray head assembly is mounted above the clamps. A baffle plate is provided next to the clamps. A recirculating baffle belt is wound around the baffle plate. A portion of the baffle belt is located between the product held by the clamps and the spraying area. A baffle motor is mounted on the baffle plate to drive the baffle belt to move. A scraper blade that is in contact with both sides of the baffle belt is mounted on the baffle plate.

[0006] In some implementations, the frame is equipped with a soaking tank, and a portion of the baffle belt is located within the soaking tank.

[0007] In some embodiments, a roller brush is installed in the soaking tank and is in contact with both sides of the baffle belt, and a brush motor is installed on the frame to drive the roller brush to move in the opposite direction to the baffle belt.

[0008] In some implementations, a hot air blower is installed above the soaking tank to dry both sides of the baffle belt.

[0009] In some embodiments, the frame is equipped with a lead screw slide, the lead screw slide is equipped with a moving spray plate, the nozzle assembly is mounted on the moving spray plate, and the moving spray plate is provided with a belt guide hole for the material guide belt to pass through, the width of the belt guide hole being greater than the moving stroke of the moving spray plate.

[0010] In some embodiments, the fixture includes two mutually symmetrical clamping frames, each clamping frame being provided with clamping rollers for clamping both ends of the product, and one of the clamping frames being equipped with a clamping motor for driving the clamping rollers to rotate.

[0011] In some implementations, the baffle belt is a steel belt.

[0012] In some embodiments, the frame is provided with a transverse plate, the transverse plate is equipped with a transverse slide rail and a transverse cylinder, the baffle plate is equipped with a transverse slider that cooperates with the transverse slide rail, and the transverse cylinder is connected to the baffle plate.

[0013] In some embodiments, the frame is equipped with a lifting frame, the lifting frame is equipped with a lifting slide rail and a lifting cylinder, the transverse plate is equipped with a lifting slider that cooperates with the lifting slide rail, and the lifting cylinder is connected to the transverse plate.

[0014] In some embodiments, two baffles are provided next to the fixture. The baffles are equipped with drive rollers that are connected to the baffle belt. The drive roller on one baffle is provided with a synchronous shaft that is connected to the drive roller on the other baffle. The baffle motor is connected to the synchronous shaft.

[0015] The following are the beneficial effects of the present invention:

[0016] The product spraying device prevents the spraying head assembly from spraying paint onto areas of the product that do not need to be sprayed by placing a portion of the baffle belt between the product held by the clamp and the spray head assembly. This avoids spraying paint onto areas of the product that do not need to be painted, compared to over-wrapping the product. After the product is sprayed, the product spraying device does not require a lot of manpower or equipment resources to remove the wrapping material, thereby improving the production efficiency of the product.

[0017] The product spraying device drives the baffle belt wound around the baffle plate to move via a baffle motor, thereby preventing paint from accumulating on the baffle belt above the product and causing paint to drip onto the product. At the same time, the scraper removes the paint on the baffle belt, thereby preventing paint from accumulating on the baffle belt after long-term operation. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0025] like Figures 1 to 3 As shown, the spraying device includes a frame 1, on which a clamp 2 for holding both ends of a product is mounted. A nozzle assembly 3 is mounted above the clamp 2. A baffle plate 4 is arranged beside the clamp 2. A recyclable baffle belt 41 is wound around the baffle plate 4. A portion of the baffle belt 41 is located between the product held by the clamp 2 and the spraying area. A baffle motor 42 for driving the baffle belt 41 to move is mounted on the baffle plate 4. A scraper blade 51 that is in contact with both sides of the baffle belt 41 is mounted on the baffle plate 4.

[0026] During operation, the clamp 2 clamps and fixes both ends of the product. At this time, the baffle belt 41 is located above the part of the product that does not need to be coated and below the bumper group. When the coating group sprays the product, the baffle belt 41 blocks the coating and sprays it to the part of the product that does not need to be coated. At the same time, the baffle motor 42 drives the baffle belt 41 to move in a cycle, and transfers the coating accumulated when the baffle belt 41 blocks the coating to the scraper blade 51. The scraper blade 51 scrapes off the coating on the baffle belt 41.

[0027] The product spraying device prevents the spray nozzle assembly 3 from spraying paint onto the parts of the product that do not need to be coated by positioning a portion of the baffle belt 41 between the clamp 2 and the sprayer and above the parts of the product that do not need to be coated. This is different from using waste paper to wrap the product, as it prevents paint from being sprayed onto the parts of the product that do not need to be coated. After the product is coated, the product spraying device does not require a lot of manpower or equipment resources to remove the wrapping material, thereby improving the production efficiency of the product.

[0028] The product spraying device drives the baffle belt 41, which is wound around the baffle plate 4, to move via the baffle motor 42, thereby preventing paint from accumulating on the baffle belt 41 above the product and causing paint to drip onto the product. At the same time, the scraper blade 51 scrapes off the paint on the baffle belt 41, thereby preventing paint from accumulating on the baffle belt 41 after long-term operation.

[0029] The frame 1 is equipped with an immersion tank 52, and a portion of the baffle belt 41 is located inside the immersion tank 52; the immersion tank 52 can hold an immersion solution for dissolving the paint, thereby removing the paint residue on the baffle belt 41.

[0030] The soaking tank 52 is equipped with roller brushes 53 that are in contact with both sides of the baffle belt 41. The frame 1 is equipped with a brush motor that drives the roller brushes 53 and the baffle belt 41 to move in opposite directions. The brush motor drives the roller brushes 53 and the baffle belt 41 to move in opposite directions, so that the baffle belt 41 can better remove the paint on the baffle belt 41 when it is soaked in the soaking tank 52.

[0031] A hot air blower 54 is installed above the soaking tank 52 to dry both sides of the baffle belt 41; to dry the baffle belt 41 after soaking, so as to prevent the soaking residue from remaining on the baffle belt 41.

[0032] The frame 1 is equipped with a lead screw slide 31, and the lead screw slide 31 is equipped with a transfer spray plate 32. The spray head assembly 3 is installed on the transfer spray plate 32. The transfer spray plate 32 is provided with a guide hole 33 for the material blocking belt 41 to pass through. The lead screw slide 31 drives the transfer spray plate 32 to move, thereby driving the spray head assembly 3 to move, so as to achieve more uniform spraying of paint onto the product. The width of the guide hole 33 is greater than the stroke of the lead screw slide 31 driving the transfer spray plate 32, thereby avoiding the material blocking belt 41 from blocking the movement of the transfer spray plate 32, and saving the length of the guide belt wrapped on the material blocking plate 4.

[0033] The fixture 2 includes two symmetrical clamping frames 21, which can be driven by a cylinder to move closer and open to clamp the toner cartridge. The clamping frames 21 are equipped with clamping rollers 22 for clamping the two ends of the product. One of the clamping frames 21 is equipped with a clamping motor that drives the clamping rollers 22 to rotate, thereby causing the clamped product to rotate and thus achieving uniform coating of paint around the product.

[0034] The guide belt 41 is made of steel to reduce wear on the guide belt 41.

[0035] The frame 1 is equipped with a transverse plate 61, which is fitted with a transverse slide rail 62 and a transverse cylinder 63. The baffle plate 4 is fitted with a transverse slider 64 that cooperates with the transverse slide rail 62. The transverse cylinder 63 is connected to the baffle plate 4. The transverse cylinder 63 drives the baffle plate 4 to move on the transverse slide rail 62, thereby adjusting the position of the baffle strip 41 when it is above the product. This allows the baffle strip 41 to more accurately cover the parts of the product that do not need to be coated when the spraying group sprays paint onto the product.

[0036] The frame 1 is equipped with a lifting frame 71, which is equipped with a lifting slide rail 72 and a lifting cylinder 73. The transverse plate 61 is equipped with a lifting slider 74 that cooperates with the lifting slide rail 72. The lifting cylinder 73 is connected to the transverse plate 61. The lifting cylinder 73 drives the transverse plate 61 to move up and down on the lifting slide rail 72, thereby adjusting the height of the baffle belt 41 so that the baffle belt 41 can be adjusted to better accommodate products of different diameters or so that the clamp 2 can more easily clamp the products.

[0037] When two baffle plates 4 are provided next to the fixture 2, the baffle plates 4 are equipped with drive rollers 44 that are connected to the baffle belts 41. The drive rollers 44 on one baffle plate 4 are provided with a synchronous shaft 43 that is connected to the drive rollers 44 on the other baffle plate 4. The synchronous shaft 43 is a splined shaft. The drive rollers 44 are provided with splined holes that mate with the splined shaft. The baffle motor 42 is connected to the synchronous shaft 43 so that one baffle motor 42 can synchronously drive the two baffle belts 41 to move synchronously, thereby reducing the size and cost of the equipment.

[0038] It should be understood that the specific embodiments described above are for illustrative purposes only and are not intended to limit the scope of the invention. Therefore, any modifications, equivalent substitutions, or improvements made without departing from the spirit and scope of the invention should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or their equivalents.
