Description

Technical Field

[0001] This utility model relates to the field of polyurethane paint production technology, and in particular to a defoaming device for the mixing and stirring process of polyurethane paint. Background Technology

[0002] Polyurethane paint, also known as polyurethane varnish, produces a tough, glossy film with strong adhesion, and is water-, abrasion-, and corrosion-resistant. It is widely used in high-end wooden furniture and can also be applied to metal surfaces.

[0003] In the existing technology, during the stirring process of polyurethane paint production, because the mixing tank contains air, air is mixed into the raw materials during high-speed stirring, which will generate bubbles. These bubbles need to be eliminated in time to avoid affecting the production of polyurethane paint. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that during the production of polyurethane paint, when the mixing tank contains air, air mixes into the raw materials during high-speed mixing, generating bubbles that need to be eliminated in time to avoid affecting the production of polyurethane paint. Therefore, this invention proposes a defoaming device for the mixing and stirring process of polyurethane paint.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a defoaming device for the mixing and stirring process of polyurethane paint, comprising a defoaming mechanism, the defoaming mechanism comprising a hollow tube, one end of which is fixedly connected to a retaining ring, the other end of which is fixedly connected to an end plate, an air bladder being provided at the lower end of the end plate, a second threaded hole being provided on the outer surface of the hollow tube, a threaded rod being threadedly connected inside the second threaded hole, and a defoaming rod being fixedly connected at the lower end of the threaded rod.

[0006] Preferably, a base plate is fixedly connected to the lower end of one side of the end plate, and a No. 1 threaded hole is opened in the middle of the base plate.

[0007] Preferably, the internal thread of the No. 1 threaded hole is connected to an adjusting bolt, and the lower end of the adjusting bolt is rotatably connected to a base plate, with the airbag fixedly connected to the base plate.

[0008] Preferably, the end plate has an inner sliding rod that is slidably connected inside, and the lower end of the inner sliding rod is fixedly connected to the bottom plate.

[0009] Preferably, a delay mechanism is provided on one side of the base plate, the delay mechanism including a rubber pad located at the end of the base plate.

[0010] Preferably, insertion holes are provided on both sides of the middle part of one end of the base plate, and sliding rods are fixedly connected to both sides of the middle part of one side of the rubber pad, with the sliding rods slidably connected to the insertion holes.

[0011] Preferably, a spring is fixedly connected between the end of the slide rod and the insertion hole.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the retaining ring is installed on the shaft of the stirring equipment. The air bladder allows the defoaming mechanism to be positioned above the liquid surface by utilizing buoyancy. In this way, during stirring, the defoaming rod can puncture the air bubbles, eliminating the internal air bubbles and preventing them from affecting the quality of the polyurethane paint.

[0014] 2. In this utility model, by setting up a delay mechanism, the rubber pad can be squeezed against the inner wall of the stirring device by the spring during use. In this way, the hollow tube can be prevented from rotating at the same speed as the paint liquid, thereby increasing the defoaming effect. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides a defoaming device for the mixing and stirring process of polyurethane paint, including a defoaming mechanism 1. The defoaming mechanism 1 includes a hollow tube 11, one end of which is fixedly connected to a retaining ring 12, and the other end of the defoaming mechanism 1 is fixedly connected to an end plate 15. An air bladder 18 is provided at the lower end of the end plate 15. A second threaded hole 111 is opened on the outer surface of the hollow tube 11, and a threaded rod 112 is threadedly connected inside the second threaded hole 111. A defoaming rod 13 is fixedly connected at the lower end of the threaded rod 112. The outer surface of the retaining ring 12 has a conical spiral pattern.

[0024] The specific settings and functions of this embodiment are described in detail below. The retaining ring 12 is installed on the shaft of the stirring device. The air bladder 18 is used to make the defoaming mechanism 1 located above the liquid surface by using buoyancy. In this way, during stirring, the defoaming rod 13 can puncture the air bubbles to make the interior free of air bubbles, so as to avoid the air bubbles affecting the quality of the polyurethane paint.

[0025] Example 2: Figure 1 - Figure 3 As shown, a base plate 14 is fixedly connected to the lower end of one side of the end plate 15. A threaded hole 110 is opened in the middle of the base plate 14. An adjusting bolt 19 is threaded inside the threaded hole 110. The lower end of the adjusting bolt 19 is rotatably connected to a base plate 17. The airbag 18 is fixedly connected to the base plate 17. An inner slide rod 16 is slidably connected inside the end plate 15. The lower end of the inner slide rod 16 is fixedly connected to the base plate 17. A delay mechanism 2 is provided on one side of the base plate 14. The delay mechanism 2 includes a rubber pad 21. The rubber pad 21 is located at the end of the base plate 14. Insertion holes 24 are opened on both sides of the middle of one end of the base plate 14. A slide rod 22 is fixedly connected to both sides of the middle of one side of the rubber pad 21. The slide rod 22 is slidably connected to the insertion hole 24. A spring 23 is fixedly connected between the end of the slide rod 22 and the insertion hole 24.

[0026] The overall effect of this embodiment is that, by setting the delay mechanism 2, the spring 23 can press the rubber pad 21 against the inner wall of the stirring device during use. In this way, the hollow tube 11 can not rotate at the same speed as the paint liquid, thereby increasing the defoaming effect.

[0027] The usage and working principle of this device are as follows: When in use, place the two retaining rings 12 on both sides of the stirring rod, and then use bolts to connect and fix the two ends of the retaining rings 12. Then press the rubber pad 21 to make the slide rod 22 slide into the spring 23. Place the stirring rod in the mixing tank, release the rubber pad 21, and the rubber pad 21 will squeeze the inner wall of the mixing tank. Turn on the stirring equipment. As the stirring rod rotates, it will drive the polyurethane paint raw materials to rotate together and mix. At the same time, the hollow tube 11 will rotate, and the generated air bubbles will be punctured by the defoaming rod 13.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
