[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0034] First embodiment

[0035] ​The paint flow guide device is a tool or equipment for controlling and guiding the flow of paint. Its main function is to ensure the uniform distribution of paint on the surface of the object to be painted, improve the painting effect and quality. The traditional flow guide device is installed on the discharge pipe 3 of the spray gun. Since different types of spray guns have different diameters of discharge pipes 3, different flow guide devices need to be adapted to different spray guns, which not only affects the application range of the flow guide device, but also reduces the practicability of the flow guide device. In order to prevent the existing flow guide device from being difficult to adapt to different spray guns and causing limitations, referring to Figure 1 Figure 7 The present embodiment provides an environmentally friendly paint flow guide device, which is composed of a nozzle 1, a flow guide pipe 2, a discharge pipe 3 and a flow guide assembly 5. The flow guide pipe 2 is arranged at the top of the nozzle 1, and the discharge pipe 3 is installed at the top of the flow guide pipe 2. At the same time, the top of the discharge pipe 3 is installed at the bottom of the external paint spray gun. The spray gun belongs to the prior art, and its specific structure is not described in detail in this application.

[0036] The flow guide assembly 5 is arranged inside the flow guide pipe 2 and is used to connect the nozzle 1 and the discharge pipe 3, so as to ensure the stable use of the flow guide device. The flow guide assembly 5 includes a receiving hopper 51 arranged at the bottom of the inner side of the flow guide pipe 2. The bottom of the receiving hopper 51 penetrates the flow guide pipe 2 and rotates with it through a bearing. The top of the receiving hopper 51 is conical. The top of the receiving hopper 51 matches the bottom of the discharge pipe 3. The bottom of the discharge pipe 3 is in contact with the inner wall of the top of the receiving hopper 51. It can guide the flow of the discharge pipe 3 with different diameters. A sealing sleeve 52 is threadedly arranged at the top of the nozzle 1 and fixed at the bottom of the flow guide pipe 2. The bottom of the receiving hopper 51 is fixed with a discharging ring 53 matching the top of the nozzle 1. The top of the nozzle 1 is inserted into the bottom of the receiving hopper 51 and rotates with it. The nozzle 1 is detachably installed at the bottom of the flow guide pipe 2. The top of the nozzle 1 is in contact with the discharging ring 53, which ensures the sealing between the nozzle 1 and the receiving hopper 51, so as to ensure the sealing between the receiving hopper 51 and the discharge pipe 3 and the nozzle 1, so as to ensure that the flow guide pipe 2 will not produce harmful gas or pollute the environment during use, and enhance the environmental protection performance of the flow guide device.

[0037] The inner side of the receiving hopper 51 is detachably provided with a filter screen 54. The top of the filter screen 54 is fixed with a stirring rod 55. The receiving hopper 51 can simultaneously drive the filter screen 54 and the stirring rod 55 to rotate, so as to avoid the clogging of the paint in the receiving hopper 51. At the same time, the filter screen 54 can also filter the impurities and particles in the paint, preventing them from clogging the nozzle 1 or affecting the painting quality.

[0038] Further, in order to ensure that the paint flows more smoothly during the flow of the receiving hopper 51, and will not appear the situation of blockage, referring to Figure 4 ​The inner bottom of the flow guide pipe 2 is provided with a driving assembly 56 for driving the receiving hopper 51 to rotate. The driving assembly 56 comprises a supporting ring 561 which is detachably arranged on the inner bottom of the flow guide pipe 2 and is matched with the receiving hopper 51. A transmission gear ring 562 which is detachably connected with the receiving hopper 51 is arranged on the bottom of the supporting ring 561. A driving gear 563 is arranged on one side of the transmission gear ring 562. A servo motor 564 for driving the driving gear 563 to rotate is fixed on the bottom of the flow guide pipe 2. The output shaft of the servo motor 564 is fixedly connected with the driving gear 563.

[0039] When the servo motor 564 is started, the driving gear 563 is driven to rotate, the transmission gear ring 562 on one side of the driving gear 563 is driven to rotate, the receiving hopper 51 on the transmission gear ring 562 is driven to rotate on the inner side of the flow guide pipe 2, the filter screen 54 on the inner side of the receiving hopper 51 is driven to rotate, and the stirring rod 55 on the top of the filter screen 54 is driven to rotate. Thus, the paint on the inner top of the receiving hopper 51 is stirred, which not only prevents the paint from being blocked in the receiving hopper 51, but also further stirs and mixes the paint. Meanwhile, the filter screen 54 further filters the impurities and particles in the paint, which prevents them from blocking the nozzle 1 or affecting the coating quality.
