Technical Field
[0001] This utility model relates to the field of servo motor technology, specifically to a paint mixing device for building construction. Background Technology
[0002] In construction, the quality of paint mixing has a significant impact on the final coating effect. Existing paint mixing devices suffer from uneven mixing, particularly failing to fully mix the paint at the bottom. Furthermore, most mixing devices lack an effective paint circulation system, hindering thorough mixing and compromising on application quality. Therefore, there is an urgent need for a paint mixing device that can effectively improve mixing uniformity and circulation. Utility Model Content

[0005] Preferably, positioning ear plates are fixedly installed on the feed sleeve and the discharge sleeve. The positioning ear plates have threaded holes, and the bottom plate of the hand-held part has threaded grooves. The positioning ear plates are fixed by positioning bolts.
[0006] Preferably, the discharge port is located above the first stirring blade.
[0007] Preferably, both the feed sleeve and the discharge sleeve are composed of a cylinder and two sealed bearings, with the two sealed bearings nested at opposite ends of the cylinder, and a pipe joint is installed through the sleeve.
[0008] Preferably, the liquid pump is connected to the inlet sleeve and the outlet sleeve via a gooseneck tube.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] This utility model device has an ingenious structure. The stirring rod has a double-chamber structure. Through the design of the liquid pump and the double-chamber structure of the stirring rod, the paint can be circulated and flowed, so that the paint at the bottom can be fully sucked up and participate in the stirring process. This effectively avoids the problem of uneven paint mixing and ensures that the composition of the entire paint system is uniform after stirring. This provides a high-quality paint base for subsequent building construction and painting, thereby improving the final painting effect and construction quality. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1 to 4This utility model provides a technical solution: a paint mixing device for building construction, including a handheld part 1, on which a motor 2 is fixedly installed, and the output shaft of the motor 2 is fixedly connected to one end of a mixing rod 3; the mixing rod 3 is a hollow structure, and the interior of the mixing rod 3 is divided into a feeding chamber 3c and a discharging chamber 3b by a partition 3a. The discharging chamber 3b is a solid structure located below the discharging hole 3e. The bottom of the mixing rod 3 is provided with a feeding hole 3d communicating with the feeding chamber 3c, and a quarter of the way from the bottom is provided with a connection to the discharging chamber 3b. The discharge port 3e is connected. The top of the stirring rod 3 is sleeved with a feed sleeve 4 and a discharge sleeve 5 through a bearing. A through hole for paint input and output is opened at the sleeve. A liquid pump 10 is installed at the bottom of the hand-held part 1. The input end of the liquid pump 10 is connected to the discharge sleeve 5 and the output end is connected to the feed sleeve 4. The stirring rod 3 is equipped with a first stirring fin 8 and a second stirring fin 9. The tilt angles of the first stirring fin 8 and the second stirring fin 9 are mirrored. During stirring, a bidirectional shearing force is generated to accelerate the mixing of the paint.
[0018] Furthermore, positioning ear plates 6 are fixedly installed on the feed sleeve 4 and the discharge sleeve 5. The positioning ear plates 6 have threaded holes, and the bottom plate of the hand-held part 1 has threaded grooves. The positioning ear plates 6 are fixed by positioning bolts 7.
[0019] Furthermore, the discharge port 3e is located above the first stirring fin 8.
[0020] Furthermore, both the feed sleeve 4 and the discharge sleeve 5 are composed of a cylinder and two sealed bearings, which are nested at both ends of the cylinder. A pipe joint is installed through the sleeve 5.
[0021] Furthermore, the liquid pump 10 is connected to the inlet sleeve 4 and the outlet sleeve 5 via a gooseneck tube.
[0022] The working process of this utility model is as follows:
[0023] like Figure 1 - Figure 4 As shown, when the device is in use, both the motor and the liquid pump 10 are connected to an external power supply and control switch. The operator holds the handheld part 1 and places the stirring device into the paint. The motor 2 is started, driving the stirring rod 3 to rotate. The first stirring blade 8 and the second stirring blade 9 perform preliminary stirring of the paint. At the same time, the liquid pump 10 is started, and the paint enters the feeding chamber 3c from the feed hole 3d, flows out through the discharge sleeve 5, then enters the discharge chamber 3b through the feed sleeve 4, and finally flows out from the discharge hole 3e. This achieves circulating stirring of the paint, avoiding the situation where the paint at the bottom sinks and cannot be stirred, and ensuring uniform stirring.
[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
