Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying devices, in particular to a paint spraying device for plastic products. Background Art

[0002] Plastic products are a general term for household and industrial products made from plastic as the primary raw material. They include products made from all processes, such as injection molding and blister molding. Plastic is a type of synthetic polymer material with plasticity. Together with synthetic rubber and synthetic fibers, it forms one of the three most indispensable synthetic materials in daily life. During processing, some plastic products require painting. Existing painting methods typically utilize manual handheld spray nozzles, requiring workers to stand close to the surface. This can easily lead to workers inhaling the spray material, which can cause significant damage to the human body over long periods of time. Furthermore, manual spraying results in poor uniformity, and only one-sided painting is possible on plastic products. This method has significant limitations, low efficiency, and poor quality, failing to meet user needs.

[0003] Patent publication number CN218796689U, entitled "A Painting Device for Plastic Product Production and Processing," addresses the aforementioned issues. However, the device can only paint one plastic product at a time and cannot simultaneously paint a large number of plastic products, thereby reducing the efficiency of plastic product production and processing. Based on this, the present utility model designs a painting device for plastic products to address the aforementioned issues. Utility Model Content

The driving component 5 includes a motor 501 fixed on the left side of the top of the shell 2. The external fixed sleeve of the head end of the motor 501 is provided with a driving gear 502. The middle end of the top of the shell 2 rotates and penetrates a rotating rod 503, and the rotating rod 503 rotates and penetrates the top of the mounting plate 3. The linkage gear 504 fixed on the upper end of the rotating rod 503 is engaged with the gear teeth of the driving gear 502. There is a first cavity 505, and a plurality of mounting rods 506 are connected to the top end of the shell 2, and the mounting rods 506 rotate and pass through the mounting plate 3. An L-shaped hole 507 is integrally provided inside the mounting rod 506, and a circular plate 508 is fixedly sleeved on the lower end of the outer portion of the mounting rod 506, and a second cavity 509 is integrally provided inside the circular plate 508.

[0027] A tank body 6 is provided on the right side of the outside of the operating table 1, and a connecting pipe 7 is fixedly passed through the top of the tank body 6. A paint pump 8 is fixedly provided at the end of the connecting pipe 7 away from the tank body 6, and the paint pump 8 is fixed on the right side of the top of the shell 2. A mounting pipe 9 is fixed on the top of the paint pump 8, and the end of the mounting pipe 9 away from the paint pump 8 rotates and passes through the top of the rotating rod 503. The staff first puts a large number of plastic products into the shell 2 through the discharge hole 4, and matches the plastic products with the circular plate 508 one by one, then turns on the motor 501 and the paint pump 8. The motor 501 controls the driving gear 502 to drive the linkage gear 504 together with the rotating rod 503 and the driving gear 512 to rotate. The driving gear 512 controls the driven gear 513 to drive the mounting rod 506 to rotate the linkage circular plate 508 and the connecting rod 510, thereby making the connecting rod 510 rotate with the center of the circular plate 508 as the center.

[0030] According to the operation method in Example 1, when the plastic product is placed inside the shell 2, the placement plate 13 supports the plastic product, thereby ensuring the stability of the one-to-one correspondence between the plastic product and the circular plate 508. Before starting the motor 501 and the paint pump 8, the staff first turns on the suction function of the dual-purpose pump 17, and then discharges the gas inside the suction nozzle 14, the yield hole 15 and the third cavity 10 through the exhaust hole 16 through the dual-purpose pump 17 to the outside world. At this time, the negative pressure attraction generated inside the suction nozzle 14 fixes the position of the plastic product placed on the placement plate 13.
