Description

Technical Field

[0001] The utility model relates to the technical field of coating processing equipment, in particular to a premixer for the production of thermosetting powder coatings. Background Technique

[0002] Thermosetting coatings refer to coatings with thermosetting resins as the main film-forming substances. When these coatings cure, the film-forming substances in the coating film undergo cross-linking and other reactions to become a hard and insoluble three-dimensional polymer network structure. The main varieties include amino alkyd coatings, thermosetting acrylic coatings, epoxy resin coatings, polyester coatings, polyurethane coatings, etc.

[0003] Chinese Patent (Publication No.: CN216465505U) discloses a premixer for the production of thermosetting powder coatings, including a crushing box and a stirring box. The crushing box is fixedly installed at the top of the stirring box, and transportation boxes are fixedly installed at both ends of the crushing box. A crushing and separating mechanism for initially crushing the coating is installed inside the crushing box; in this utility model, due to the inverted V-shaped structure of the separation and screening plate, larger particle powder coatings will flow into the grooves on both sides of the top of the separation and screening plate, and then because the groove depth gradually deepens from the outside to the inside, the powder coatings will finally move into the arc-shaped groove. Through the tangential structure of the discharge port and the arc-shaped groove, the larger particle powder coatings can be transported into the transportation box. The chopping knife holder is located at the outlet of the feeding port, and the coating can be transported to the feeding port by a screw conveyor and then chopped twice by the chopping knife holder. Through repeated operations, the larger particle powder coatings can be crushed as much as possible for subsequent mixing and stirring; however, when discharging, the discharge port needs to be manually opened, and then the stirring box discharges materials, with low working efficiency.

[0004] To solve the above problems, we made improvements and proposed a premixer for the production of thermosetting powder coatings. Content of the Utility Model

Specific embodiments

[0020] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0021] Example: As Figures 1-3 shown, a premixer for the production of thermosetting powder coatings includes a top bottom plate 1. A support 2 is fixedly connected to the top end of the bottom plate 1. A crushing box 3 is fixedly installed at the top end of the support 2. A mixing box 4 is fixedly connected to the bottom end of the crushing box 3. An outlet is provided at the bottom of the mixing box 4. A plugging block 12 is arranged inside the outlet. A second telescopic cylinder 13 is fixedly connected to the bottom end of the plugging block 12. A base 14 is fixedly connected to the bottom end of the second telescopic cylinder 13. The base 14 is fixedly connected to the bottom of the mixing box 4 through a connecting rod 15. A mixing structure is arranged inside the mixing box 4;

[0022] The raw materials enter the crushing box 3 and are crushed, and then fall into the mixing box 4. The mixing mechanism stirs the coatings. After the stirring is completed, the second telescopic cylinder 13 works to push the plugging block 12 upward into the mixing box 4. The plugging block 12 is separated from the outlet, and the coatings are discharged from the outlet, assisting in discharging and improving the working efficiency.

[0023] Specifically, as Figure 2 shown, the mixing structure includes a mounting frame 8, and the mounting frame 8 is fixedly connected to the bottom of the mixing box 4. A motor 9 is fixedly connected to the top end of the mounting frame 8. The output end of the motor 9 is fixedly connected to a mixing arm 10. The output end of the motor 9 is fixedly connected to a mixing rod 11, and the mixing rod 11 extends towards the bottom of the mixing box 4. The mounting frame 8 fixes the motor 9, so that there is no obstruction above the outlet. The motor 9 works to drive the mixing arm 10 to rotate, thereby stirring the coatings. The mixing rod 11 extends to the bottom of the mixing box 4, and can stir the coatings at the bottom of the mixing box 4, improving the mixing effect.

[0024] Specifically, as Figure 2 and Figure 3As shown in the figure, a guide rail 16 is fixedly connected to the bottom of the stirring tank 4. A slider 18 is slidably connected to the outside of the guide rail 16. A lever 17 is fixedly connected to the bottom of the slider 18. A motor is fixedly installed inside the slider 18. The output end of the motor is fixedly connected to a driving rod 19, and the driving rod 19 cooperates with the stirring rod 11. When the motor works, the driving rod 19 moves, making the driving rod 19 coincide with the stirring rod 11. The rotating stirring rod 11 acts on the driving rod 19, causing the slider 18 to slide along the guide rail 16, and then making the lever 17 rotate inside the stirring tank 4. The lever 17 pushes the paint at the bottom of the stirring tank 4, pushing the paint at the bottom of the stirring tank 4 towards the discharge port, assisting the paint to be discharged, and further improving the working efficiency.

[0025] Specifically, as Figure 1 shown in the figure, a slope 5 is fixedly connected to the top end of the bottom plate 1, and the slope 5 is arranged below the top end of the stirring tank 4. A support seat 6 is arranged between the slope 5 and the bottom plate 1. A first telescopic cylinder 7 is fixedly installed at the top of the slope 5, and the movable end of the first telescopic cylinder 7 penetrates to the upper end surface of the slope 5. The material receiving box moves along the slope 5 to the lower part of the stirring tank 4, and then the first telescopic cylinder 7 extends to limit the material receiving box, avoiding manual support and making it more convenient to use.

[0026] Working principle: The material receiving box moves along the slope 5 to the lower part of the stirring tank 4, and then the first telescopic cylinder 7 extends to limit the material receiving box. The raw materials enter the crushing box 3 and are crushed, and then fall into the stirring tank 4. The motor 9 works to drive the stirring arm 10 to rotate, thereby stirring the paint. The stirring rod 11 extends from the bottom of the stirring tank 4 and can stir the paint at the bottom of the stirring tank 4. After the stirring is completed, the second telescopic cylinder 13 works to push the blocking block 12 into the stirring tank 4. The blocking block 12 is separated from the discharge port, and the paint is discharged from the discharge port. The motor works to make the driving rod 19 move, making the driving rod 19 coincide with the stirring rod 11. The rotating stirring rod 11 acts on the driving rod 19, causing the slider 18 to slide along the guide rail 16, and then making the lever 17 rotate, pushing the paint at the bottom of the stirring tank 4 towards the discharge port to assist the paint to be discharged.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
