Description

Technical Field

[0001] This utility model relates to the field of ABS plastic processing technology, specifically to a surface hardening spraying device for ABS plastic processing. Background Technology

[0002] ABS plastic surface hardening spray coating treatment is mainly used to improve the wear resistance and scratch resistance of ABS plastic products. ABS has low original hardness and is prone to scratches from frequent friction. Spraying a hardening coating can increase its hardness, such as in car dashboards and electronic product housings. Before spraying, ABS plastic products are usually flame treated. Flame treatment can clean the surface and increase active genes, improving coating adhesion. However, because the surface temperature of ABS plastic after flame treatment is high, it is not suitable for direct spraying. Furthermore, if the ABS plastic surface is transferred for drying before initial drying after spraying, sagging is likely to occur on the ABS plastic surface. Utility Model Content

[0028] This utility model provides a surface hardening spraying device for ABS plastic processing. After the ABS plastic is flame-treated, it is rotated to the underside of the air-cooling rack by the rotation of the turntable. The ABS plastic is cooled by the fan.

[0029] Figures 1-6 The diagram shown is an overall structural schematic of one embodiment of the surface hardening spraying device for ABS plastic processing according to this utility model. Please refer to [link / reference]. Figures 1-6This embodiment of an ABS plastic processing surface hardening spraying device includes a device body 1. A first drive shaft 2 is rotatably connected to the inner top of the device body 1. A first gear 3 is fixedly disposed through the outer ring of the first drive shaft 2 near the lower part. The first gear 3 is meshed with a second gear 4. The second gear 4 is fixedly disposed through the outer ring of a first rotating shaft 5. The first rotating shaft 5 is connected to the output shaft of a first motor 6. The first motor 6 is disposed inside the device body 1. A turntable 7 is fixedly connected to the upper end of the first drive shaft 2. Six second drive shafts 8 are rotatably connected through the turntable 7 in a circular array. A storage tray 9 is fixedly connected to the upper end of the second drive shafts 8. The second drive shafts 8 are connected to the output shaft of a second motor 11 through a meshing gear set 10. The second motor 11 is disposed at the lower end of the turntable 7.

[0030] The device body 1 has six trays 9 arranged in a circular array. Under the action of the first motor 6, the first rotating shaft 5, the second gear 4, the first gear 3, and the first transmission shaft 2, the turntables 7 are rotated and adjusted. This is used for continuous processing of ABS plastic products for flame treatment, cooling, spraying, and pre-curing. The second motor 11 drives the second transmission shaft 8 to rotate through the meshing gear set 10, thereby rotating and adjusting the ABS plastic products on the trays 9. This helps to ensure that the ABS plastic products are flame treated, cooled, sprayed, and pre-cured evenly and fully. An angle sensor is provided to detect and control the rotation adjustment of the turntables 7 driven by the first transmission shaft 2. The first transmission shaft 2 rotates the turntables 7 by 60° each time. The angle sensor detection and control of the rotation angle is a prior art structure, and the angle sensor model is RSA36.

[0031] The device body 1 includes a flame treatment adjustment frame 101. The outer side wall of the device body 1 is fixedly provided with the flame treatment adjustment frame 101, the air cooling frame 102, the electrostatic spraying adjustment frame 103 and the pre-curing frame 104 in a clockwise direction.

[0032] Infrared thermometers can be installed on the flame treatment rack 101, air-cooling rack 102, and pre-curing rack 104 as needed to monitor temperature changes during the processing of ABS plastic products.

[0033] The turntable 7 includes a support rod 701 fixedly installed at the lower end of the turntable 7, and a roller 702 is connected to the lower end of the support rod 701.

[0034] The roller 702 can be set at a certain tilt angle or be a universal wheel to facilitate rotation and improve support. This part is a prior art structure and is not a novel part of this patent.

[0035] The flame treatment adjustment frame 101 includes a second rotating shaft 1011 that is rotatably connected to the side wall of the flame treatment adjustment frame 101. One end of the second rotating shaft 1011 is connected to the output shaft of the third motor 1012. A first bracket 1013 is fixedly connected to the end of the second rotating shaft 1011 away from the third motor 1012. A flame spray gun assembly 1014 is installed through the upper end of the first bracket 1013.

[0036] The ABS plastic product is flame-treated by the flame gun assembly 1014. This part of the flame gun assembly 1014 is a prior art structure. It is connected to an external gas supply device. Under the action of the third motor 1012 and the second rotating shaft 1011, the first bracket 1013 is rotated and adjusted, thereby adjusting the tilt angle of the flame gun assembly 1014, which helps to fully treat the ABS plastic product.

[0037] The air-cooled frame 102 includes a fan 1021 that is installed through the side wall of the air-cooled frame 102. An electric telescopic rod 1022 is fixedly installed through the upper end of the air-cooled frame 102. A pressure plate 1023 is rotatably connected to the telescopic end of the electric telescopic rod 1022.

[0038] The ABS plastic product is cooled by the fan 1021, and the pressure plate 1023 is pushed by the electric telescopic rod 1022 to press and limit the ABS plastic product, thereby improving the stability of the ABS plastic product during air cooling.

[0039] The electrostatic spraying frame 103 includes a third rotating shaft 1031 that is rotatably connected to the side wall of the electrostatic spraying frame 103. One end of the third rotating shaft 1031 is connected to the output shaft of the fourth motor 1032. A second bracket 1033 is fixedly connected to the end of the third rotating shaft 1031 away from the fourth motor 1032. An electrostatic spray gun assembly 1034 is installed through the upper end of the second bracket 1033.

[0040] Electrostatic spraying is performed on ABS plastic products using an electrostatic spray gun assembly 1034. The electrostatic spray gun assembly 1034 is a conventional technology structure connected to an external paint supply device. The second bracket 1033 is rotated by a fourth motor 1032 and a third rotating shaft 1031, thereby adjusting the tilt angle of the electrostatic spray gun assembly 1034. This helps to fully and completely spray the ABS plastic products. During electrostatic spraying, the electrostatic field charges the paint and attracts it to the workpiece. The mechanical force on the workpiece is minimal and negligible. Therefore, when spraying ABS plastic products, unless the product is extremely light or small, there is no need for limiting or fixing.

[0041] The pre-curing rack 104 includes a lamp holder 1041 mounted on the side wall of the pre-curing rack 104, and a UV curing lamp 1042 is mounted on the lamp holder 1041.

[0042] Pre-curing of the sprayed ABS plastic products is performed using a UV curing lamp 1042 to prevent sagging on the ABS plastic surface.

[0043] Combination Figures 1-6 The surface hardening spraying device for ABS plastic processing according to this embodiment is used as follows: ABS plastic products are placed on the corresponding tray 9. The turntable 7 is rotated and adjusted by the action of the first motor 6, the first rotating shaft 5, the second gear 4, the first gear 3, and the first transmission shaft 2, moving the ABS plastic products to a position below the flame treatment frame 101. The ABS plastic products are then flame-treated by the flame gun assembly 1014. The first support 1013 is rotated and adjusted by the action of the third motor 1012 and the second rotating shaft 1011, thereby adjusting the tilt angle of the flame gun assembly 1014, which helps to fully treat the ABS plastic products. After flame treatment, the products are rotated to a position below the air-cooling frame 102, where the fan 1021 cools the ABS plastic products. The telescopic rod 1022 pushes the pressure plate 1023 to press and limit the ABS plastic product, improving the stability of the ABS plastic product during air cooling. After cooling, it rotates to the bottom of the electrostatic spraying frame 103, and electrostatic spraying is performed on the ABS plastic product by the electrostatic spray gun assembly 1034. The second bracket 1033 is rotated by the fourth motor 1032 and the third rotating shaft 1031, thereby driving the electrostatic spray gun assembly 1034 to adjust the tilt angle, which helps to fully spray the ABS plastic product. After spraying, it rotates to the bottom of the pre-curing frame 104, and the sprayed ABS plastic product is pre-cured by the UV curing lamp 1042. The two pre-curing frames 104 help to fully pre-cur the ABS plastic product. The device is controlled by a controller, model TrioMC405.
