[0002] Paint, as the core component of color paint, covers all liquid components and is an indispensable finished product in the paint manufacturing process. In actual production and application, the accuracy of paint proportioning is crucial. Since paint has better fluidity and mixing properties in liquid state, the proportioning process is usually carried out for fluid paint;

[0003] In the process of paint production and preparation, in order to meet the performance requirements of the product and the personalized needs of customers, the paint must be accurately proportioned. For example, when coloring the base fluid paint, it is usually necessary to mix the base fluid paint with the pigment paste in a specific proportion to achieve the desired color effect. The traditional paint proportioning process often relies on manual operation, which is not only inefficient but also difficult to ensure the accuracy of the proportioning. In addition, due to the diversity and complexity of paint components, errors may occur in the proportioning process, thereby affecting product quality. Therefore, we propose a paint proportioning mixing device. Utility Model Content

The piston 53 is driven to move in the proportioning pipeline 51 by the electric telescopic rod 52. When the electric telescopic rod 52 is retracted, the proportioning pipeline 51 is The negative pressure generated in the pipeline 51, under the influence of this negative pressure, the first one-way valve 13 is passively opened, so that the paint liquid or pigment paste in the material tank 4 enters the proportioning pipeline 51, so as to obtain a certain proportion of liquid, and the electric telescopic rod 52 pushes the piston 53 to move toward the block 54 until the piston 53 contacts the block 54. Under the action of pressure, the second one-way valve 14 on the feed pipe 12 is forced to open, and the liquid in the proportioning pipeline 51 is transported to the mixing device 6. The discharge end of the feed pipe 12 is respectively connected to the inside of the mixing device 6. The mixing device 6 is composed of a mixing pipeline 61, a motor 62, a rotating shaft 63, a spiral blade 64, a discharge pipe 65 and a first electric valve 66. The mixing pipeline 61 is arranged at the bottom of the box frame 1.The front and rear ends of the top of the mixing pipe 61 are fixedly connected to the bottom of the feeding pipe 12 respectively, and the interior of the mixing pipe 61 is communicated with the interior of the feeding pipe 12 respectively. A rotating shaft 63 is provided in the middle of the inner side of the mixing pipe 61. The right end of the rotating shaft 63 is rotatably connected to the inner side of the mixing pipe 61 through a bearing. The left end of the rotating shaft 63 is fixedly connected to the output shaft end of the motor 62 fixedly installed at the left end of the mixing pipe 61. The surface of the rotating shaft 63 is welded with spiral blades 64. The spiral blades 64 are respectively in active contact with the inner wall of the mixing pipe 61. A discharge pipe 6 is provided at the right end of the bottom of the mixing pipe 61. 5, a first electric valve 66 is arranged in the middle of the discharge pipe 65, which is operated by the motor 62, and the driving shaft 63 drives the spiral blade 64 to evenly stir and mix the liquid entering the mixing pipe 61. After the mixing is completed, the first electric valve 66 is opened to discharge the mixed paint liquid from the discharge pipe 65. The controller 3 is also included.

[0020] The working principle of the utility model is as follows: when in use, the second electric valve 8 is opened through the controller 3, so that the external paint liquid and pigment paste are respectively delivered to the material tank 4 through the feed pipe 7. Since the interior of the material tank 4 is in a "sealed" state, and the discharge pressure of the first one-way valve 13 is greater than the pressure of the exhaust air and the inhaled air of the breathing valve 10, the air inside the material tank 4 is squeezed by the liquid during the process of entering the interior of the material tank 4 and is discharged outward from the breathing valve 10. After the material liquid is delivered, the second electric valve 8 is closed, and then according to the paint ratio requirements, the controller 3 is used to select the material tank 4 that stores the pigment paste and paint liquid, and then the telescopic distance of the electric telescopic rod 52 is set. The electric telescopic rod 52 is extended and retracted according to the set length to move the piston 53 in the proportioning pipe 51. When the electric telescopic rod 52 is retracted, the negative pressure generated in the proportioning pipe 51 is under the influence of this negative pressure. When the pressure inside the tank 4 is too low, the breathing valve 10 inhales air to keep the pressure inside the tank balanced. Since the retracted length of the telescopic end of the electric telescopic rod 52 is set in advance, the required proportion of the liquid can be accurately obtained. Then, when the electric telescopic rod 52 pushes the piston 53 to move toward the block 54 until the piston 53 contacts the block 54, the second one-way valve 14 on the discharge pipe 12 is forced to open under the action of pressure, and the liquid in the proportioning pipe 51 is discharged to the mixing pipe 61 through the discharge pipe 12. Then, the motor 62 is turned on by the controller 3 to drive the rotating shaft 63 to drive the spiral blade 64 to evenly stir and mix the liquid entering the mixing pipe 61. Finally, the first electric valve 66 is opened to discharge the mixed paint liquid from the discharge pipe 65.
