Technical Field
[0001] This utility model relates to the field of paint filling, specifically to an anti-skinning agent addition device for a semi-automatic paint filling machine. Background Technology
[0002] During storage, paints may develop a skin-like coating due to factors such as excessively high storage temperatures or improper container sealing. Anti-skinning agents, as additives that delay the skin-forming time of paints, can prevent skin formation during storage without altering the paint's drying properties, color, or odor.
[0003] To achieve precise metered dispensing of anti-skinning agent, the paint filling machine has been modified to include an anti-skinning agent addition device. This prevents the paint from forming a skin during storage, thereby improving the paint's storage stability and ensuring product quality. Utility Model Content

Detailed Implementation
[0017] The technical solutions of this invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] Please see the appendix Figure 1-4 As shown in the figure, the anti-skinning agent addition device for a semi-automatic paint filling machine provided in this embodiment includes an anti-skinning agent tank 1, a roller conveyor 9, and a support frame 2. The anti-skinning agent tank 1 is installed on the top of the support frame 2, and the support frame 2 is fixed to the side plate of the roller conveyor 9. A pneumatic filling valve 6 is installed at the bottom of the anti-skinning agent tank 1, and a drainage mechanism 7 is installed inside. A liftable barrel-blocking mechanism 4 is also installed between the side plates of the roller conveyor 9.
[0019] In this embodiment, after the semi-automatic paint filling machine 10 fills the paint, the roller conveyor 9 transports the paint bucket to the bottom of the anti-skinning agent tank 1 containing the anti-skinning agent, and the anti-skinning agent is added by controlling the pneumatic filling valve 6 to open.
[0020] Specifically, the unblocking mechanism 7 includes a stirring shaft 703 and an anchor mixer 704. The upper part of the stirring shaft 703 is rotatably mounted on the anti-scabbing agent tank 1, and the anchor mixer 704 is mounted on the lower part of the stirring shaft 703. A pneumatic motor 701 is connected to the upper end of the stirring shaft 703 via a coupling 702. The pneumatic motor 701 is fixed to the top of the anti-scabbing agent tank 1 and is connected to an air compressor 8 via an air circuit. The pneumatic motor 701 drives the stirring shaft 703 to rotate, thereby rotating the anchor mixer 704 and ensuring a stable output of the anti-scabbing agent.
[0021] Specifically, the barrel-blocking mechanism includes a barrel-blocking column 401, a support rod 402, a fixing plate 403, and a cylinder 404. The support rod 402 is fixedly connected at both ends to the side plate of the roller conveyor 9. The cylinder 404 is mounted on the support rod 402 via the fixing plate 403. The cylinder 404 is equipped with a compressed air interface 405, which is connected to the air compressor 8. A detection photoelectric sensor 3 is also installed on the side plate of the roller conveyor 9. The detection photoelectric sensor 3 is electrically connected to a PLC control panel 5 installed on the support frame 2. The PLC control panel 5 is also electrically connected to the pneumatic filling valve 6 and the air compressor 4. The detection photoelectric sensor 3 detects whether the paint barrel has reached the designated position, and the detection photoelectric sensor 3 is linked with the cylinder 404 and the pneumatic filling valve 6.
[0022] The working principle of this utility model is as follows: After the semi-automatic paint filling machine 10 fills the paint, the paint bucket is transported by the roller conveyor 9. When the photoelectric sensor 3 detects that the paint bucket has reached the designated position, it sends a feedback signal to the PLC controller set in the PLC control panel 5. The PLC controller sends instructions to the air compressor 8 and the pneumatic filling valve 6 in turn. After the air compressor 4 starts working, the compressed air output is delivered to the cylinder 404, the pneumatic motor 701, and the pneumatic filling valve 6 respectively. Through the action of the cylinder 404, the barrel blocking column 401 extends from the bottom of the roller conveyor 9 to block the paint bucket. The paint bucket is located in the anti-skinning agent filling area directly below the pneumatic filling valve 6. At this time, the pneumatic filling valve 6 opens, and the anti-skinning agent in the anti-skinning agent tank 1 is injected into the paint bucket. After the quantitative filling is completed, the pneumatic filling valve 6 automatically closes, the barrel blocking column 401 descends and resets, and the roller conveyor 9 transports the paint bucket out of the anti-skinning agent filling area. During the addition of the anti-skinning agent, the pneumatic motor 701 drives the stirring shaft 703 to rotate the anchor mixer 704, ensuring a stable output of the anti-skinning agent. The anti-skinning agent addition time can be preset via the PLC control panel 5, and the pneumatic filling valve 6 can be controlled by the PLC controller to achieve quantitative addition of the anti-skinning agent.
[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
