Description

Technical Field

[0001] The present application relates to the technical field of thermoplastic elastic material processing, and in particular to a spraying device for thermoplastic elastic material used in cleaning brush processing. Background Art

[0002] Thermoplastic elastomers (TPE) are a class of materials that soften when heated, solidify when cooled, and can be processed and reused repeatedly. They combine the elasticity of rubber and the processing properties of plastics and are often used to manufacture a variety of products, including cleaning brushes. Thermoplastic elastomers of cleaning brushes are usually sprayed to add additional features to the product, such as color, anti-slip or enhanced durability. Commonly used materials are polyurethane coatings and epoxy resin coatings.

[0003] At present, when the surface of the thermoplastic elastic bristles used in the cleaning brush is sprayed, some of the paint and protective liquid sprayed out by the spray gun will drip onto the processing table, and the material receiving frame provided is generally removed for processing after all the spraying processes are completed, and cannot be removed after the spraying process is completed. This causes the sprayed paint in the material receiving frame to adhere after drying, thereby reducing the recovery amount of the spraying and polluting the material receiving frame. Therefore, a spraying device for thermoplastic elastic material for complex brush processing is designed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The present application embodiment discloses a spraying device for thermoplastic elastic material for cleaning brush processing. Figure 1-3 A spraying device for thermoplastic elastic material for cleaning brush processing, comprising a fixed frame 1, the upper end of the fixed frame 1 is fixedly connected to the spray box 2, the middle part of the fixed frame 1 is rotatably connected to the first gear 5, the front side of the first gear 5 is meshed with the first gear plate 6, the upper end of the first gear plate 6 is fixedly connected to the mounting frame 61, the upper end of the mounting frame 61 is fixedly connected to the fixing plate 8, one side of the fixing plate 8 is rotatably connected to the clamping frame 10, one side of the rear end of the first gear 5 is meshed with the second gear plate 7, and the upper end of one side of the second gear plate 7 is fixedly connected to the connecting block 11, the upper end of the connecting block 11 is rotatably connected to the mounting block 13, and one side of the mounting block 13 is plugged into the material receiving frame 14, and the No. 1 gear plate 6 drives the No. 1 gear 5 to rotate, so that the No. 1 gear 5 drives the No. 2 gear plate 7 to move, so that the material receiving frame 14 can follow the movement of the clamping frame 10 and move closer to or away from the spray box 2, so that the material receiving frame 14 can be transported out of the spray box 2 every time after receiving the paint, and can be cleaned and replaced in time to prevent the paint from drying and adhering to the material receiving frame 14 to cause pollution and waste;

[0022] By adopting the above technical solution, one side of the clamping frame 10 passes through one side of the fixed plate 8 and is fixedly connected to the reducer, and one side of the reducer is fixedly connected to the servo motor 9. The servo motor 9 can be started to drive the clamping frame 10 to rotate slowly and drive the brush to rotate, so that the spray gun can evenly spray the brush.

[0023] By adopting the above technical solution, the middle part of the lower end of the mounting block 13 is fixedly connected to the No. 2 gear 12, the front part of the No. 2 gear 12 engages with the No. 3 gear plate 15, one side of the No. 3 gear plate 15 is fixedly connected to the support rod, and one side of the support rod is fixedly connected to the side wall of the fixed frame 1, and the No. 2 gear 12 is driven to rotate by the No. 3 gear plate 15, so that the No. 2 gear 12 drives the mounting block 13, and the mounting block 13 drives the material receiving frame 14 to rotate, so that the material receiving frame 14 can be rotated to the side away from the spray box 2, thereby facilitating the removal and replacement of the material receiving frame 14.

[0024] By adopting the above technical solution, the spray box 2 is fixedly connected to the nozzle 3, one end of the nozzle 3 is fixedly connected to the spray gun, the upper end of the nozzle 3 is fixedly connected to the storage box 4, and a pump is also installed at the connection between the nozzle 3 and the storage box 4, which is used to transport the paint in the storage box 4 to the spray gun on one side of the nozzle 3.

[0025] By adopting the above technical solution, the lower ends of the No. 1 gear plate 6 and the No. 2 gear plate 7 are fixedly connected to the support block 16, and the lower ends of the support blocks 16 are slidably connected to the bottom wall of the fixed frame 1. The set support blocks 16 play a supporting role to ensure the stable movement of the No. 1 gear plate 6 and the No. 2 gear plate 7.

[0026] By adopting the above technical solution, one side of the No. 1 gear plate 6 is fixedly connected to the spring 62, and one side of the spring 62 is fixedly connected to the inner wall of the fixed frame 1. The set spring 62 is convenient for pushing the No. 1 gear plate 6 to move, so that the No. 1 gear plate 6 is restored, which is beneficial for the upper clamping frame 10 to drive the thermoplastic elastic brush to separate from the spray box 2.

[0027] By adopting the above technical solution, a through slot is opened on one side of the upper end of the fixing frame 1, and the through slot is slidably connected to the mounting frame 61. The through slot is used to limit the mounting frame 61, so that the mounting frame 61 drives the movement of the clamping frame 10 to be more stable.

[0028] The implementation principle of the spraying device for thermoplastic elastic material for cleaning brush processing of the embodiment of the present application is as follows: the thermoplastic elastic brush to be sprayed is mounted on the clamping frame 10, and then the No. 1 gear plate 6 is pushed, so that the No. 1 gear plate 6 drives the clamping frame 10 and the servo motor 9 on the mounting frame 61 to move, and drives the thermoplastic elastic brush into the spray box 2. At the same time, the No. 1 gear plate 6 drives the No. 1 gear 5 to rotate during the movement, and the No. 1 gear 5 drives the No. 2 gear plate 7 to move, so that the No. 2 gear plate 7 drives the mounting block 13 and the material receiving frame 14 at the upper end of the connecting block 11 to move close to the spray box 2, and the mounting block 13 When moving, it will drive the second gear 12 to move. Since the second gear 12 is meshed with the third gear plate 15, it will also rotate around its own center when moving, and drive the upper mounting block 13 and the material receiving frame 14 to rotate 180 degrees, so that the material receiving frame 14 is rotated to face the side of the spray box 2, and follows the drive of the second gear plate 7 to enter the bottom of the spray box 2, and then use the spray gun to spray the thermoplastic elastic brush, and during this period, start the servo motor 9, so that the servo motor 9 drives the clamping frame 10 to rotate slowly, and drives the brush to rotate, so that the spray gun can evenly spray the brush.

[0029] After spraying, the mounting frame 61 can be pulled away from the spray box 2, so that the No. 1 gear plate 6 drives the No. 1 gear 5 to rotate, and drives the No. 2 gear plate 7 on one side to move toward the side away from the spray box 2, and drives the mounting block 13 and the material receiving frame 14 away. After the material receiving frame 14 is completely separated from the spray box 2, the No. 2 gear plate 7 continues to drive the mounting block 13 to move, so that the No. 2 gear 12 engages with the No. 3 gear plate 15 again, and drives the material receiving frame 14 to rotate 180 degrees, so that the material receiving frame 14 is facing away from the spray box 2, and then the material receiving frame 14 is removed and replaced with a new one.
