Abstract
Description
Technical Field
[0001] This utility model relates to the field of putty production technology, specifically to a formaldehyde-free putty mixing device for interior wall latex paint. Background Technology
[0002] Putty paste is a paste-like coating made primarily from white latex, talc powder, double-flying powder, and cellulose. Currently, putty paste generally contains formaldehyde during its preparation process, and the presence of formaldehyde can harm human health. Therefore, formaldehyde-free putty paste has been developed and produced.
[0003] Formaldehyde-free putty is produced by mixing various raw materials with water in a mixing tank. Among these raw materials are powdered materials. When powdered materials come into contact with water, they tend to clump together and are not easily dispersed, resulting in poor mixing effect. Furthermore, heavier materials tend to settle at the bottom of the mixing tank, which also leads to poor mixing effect for these materials. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a formaldehyde-free putty mixing device for interior wall latex paint.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A mixing device for formaldehyde-free putty for interior wall latex paint, comprising:
[0007] A mixing tank has a vertical rod rotatably connected to its top. Multiple mixing plates are fixedly connected to the side wall of the vertical rod. First grinding tooth plates are fixedly connected to the side wall of each mixing plate away from the vertical rod. Two second grinding tooth plates are symmetrically fixedly connected to the inner wall of the mixing tank. The multiple first grinding tooth plates continuously pass over the two second grinding tooth plates during rotation. A fixing frame is fixedly connected to the upper end of the mixing tank. The upper end of the vertical rod passes through the upper end of the mixing tank and is located within the fixing frame. A motor is fixedly connected to the upper end of the fixing frame. The movable end of the motor is fixedly connected to the upper end of the vertical rod.
[0008] A loosening mechanism for loosening and mixing raw materials deposited at the bottom of a mixing tank.
[0009] Preferably, the loosening mechanism includes four rectangular rods that are slidably connected through the sealing connection below the inner wall of the mixing tank. Each of the four rectangular rods has a loosening plate fixedly connected to one end close to the other. The lower ends of the four loosening plates are in contact with the bottom of the mixing tank. The four loosening plates are symmetrically arranged. Each of the four rectangular rods has a movable plate fixedly connected to one end far from the other. The sidewalls of the movable plates near the rectangular rods are elastically connected to the sidewalls of the mixing tank by multiple springs.
[0010] Preferably, each of the four movable plates has an L-shaped plate fixedly connected to its sidewall away from the rectangular rod, and the sidewall of each of the four L-shaped plates is slidably connected to the inner wall of the fixed frame through the movable plate.
[0011] Preferably, the vertical rod is fixedly connected to two cams on the side wall inside the fixed frame. The two cams are symmetrically arranged, and the side walls of the two cams respectively fit against the side walls of the four L-shaped plates during rotation.
[0012] Preferably, a feeding pipe is fixedly connected to the upper part of the inner wall of the mixing tank, and a discharge pipe is fixedly connected to the bottom of the mixing tank. An electric butterfly valve is installed above the outlet of the discharge pipe.
[0013] This utility model has the following beneficial effects:
[0014] 1. A first grinding toothed plate and a second grinding toothed plate are set up. Multiple mixing plates rotate, driving multiple first grinding toothed plates to continuously pass over two second grinding toothed plates. As multiple raw materials flow continuously in the mixing tank, the powdered raw materials that are condensed together enter between the first grinding toothed plate and the second grinding toothed plate. This allows the condensed powdered raw materials to be ground and dispersed, accelerating the mixing efficiency of the powdered raw materials, improving the mixing quality of formaldehyde-free putty, and avoiding the situation in the prior art where powdered raw materials are easily condensed together when mixed with water, making it difficult to disperse and resulting in poor mixing effect during the mixing process.
[0015] 2. A loosening mechanism is installed, which can drive two opposing loosening plates to move back and forth, so that the loosening plates can push and loosen the raw materials deposited at the bottom of the mixing tank, further improving the mixing quality of formaldehyde-free putty and preventing the heavier raw materials from easily depositing at the bottom of the mixing tank, resulting in poor mixing effect of the raw materials in that part.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figures 1-6 A formaldehyde-free putty mixing device for interior wall latex paint includes a mixing tank 1, a feeding pipe 8 fixedly connected to the upper part of the inner wall of the mixing tank 1, and a discharge pipe 9 fixedly connected to the bottom of the mixing tank 1. An electric butterfly valve 10 is installed above the outlet of the discharge pipe 9. Figure 2 (As shown), to prevent raw materials from entering the discharge pipe 9 and thus preventing mixing.
[0025] It should be noted that the formaldehyde-free, safe and environmentally friendly interior wall latex paint putty is composed of the following raw materials in parts by weight: 40 parts of double-flying powder, 40 parts of modified talc powder, 10 parts of gypsum powder, 3 parts of polyvinyl alcohol, 2 parts of carboxymethyl cellulose, 0.5 parts of carboxymethyl starch ether, 0.5 parts of sodium rosinate, and 35 parts of water.
[0026] Preparation method of modified talc powder: Weigh talc powder, bentonite, jade powder and boron mud in a weight ratio of 6:3:2:1 and mix them evenly. Add 1.5% triethanolamine, 2% sodium polyacrylate, 1% calcium lignosulfonate and 0.8% vinyltris(β-methoxyethoxy)silane. Grind at high speed of 2000 rpm for 15 min, dry, pulverize and pass through a 400-mesh sieve. Then add an appropriate amount of water to make a slurry with a concentration of 45%. Add 2% sodium dodecylbenzenesulfonate, 4% polyvinylpyrrolidone, 5% silicone acrylic emulsion, 0.6% diethylene glycol butyl ether and 1.5% dodecyl alcohol ester. Stir for 1.5 h, filter, dry, pulverize and grind finely and pass through a 400-mesh sieve.
[0027] A vertical rod 3 is rotatably connected to the top of the mixing tank 1. Multiple mixing plates 4 are fixedly connected to the side walls of the vertical rod 3. First grinding toothed plates 5 are fixedly connected to the side walls of the mixing plates 4 away from the vertical rod 3. Two second grinding toothed plates 6 are symmetrically fixedly connected to the inner wall of the mixing tank 1. During rotation, the multiple first grinding toothed plates 5 continuously pass over the two second grinding toothed plates 6 (e.g., ...). Figure 4 As shown), a fixed frame 2 is fixedly connected to the upper end of the mixing tank 1, and the upper end of the vertical rod 3 passes through the upper end of the mixing tank 1 and is located inside the fixed frame 2. A motor 7 is fixedly connected to the upper end of the fixed frame 2, and the movable end of the motor 7 is fixedly connected to the upper end of the vertical rod 3.
[0028] During rotation, the motor 7 drives multiple mixing plates 4 to rotate via the vertical rod 3, which can mix and stir various raw materials in the mixing tank 1. The rotation of the multiple mixing plates 4 drives multiple first grinding tooth plates 5 to continuously pass over two second grinding tooth plates 6. As the various raw materials continuously flow in the mixing tank 1, the powdery raw materials that have clumped together enter between the first grinding tooth plates 5 and the second grinding tooth plates 6, which can grind and disperse the powdery raw materials, accelerate the mixing efficiency of the powdery raw materials, improve the mixing quality of formaldehyde-free putty, and avoid the situation in the prior art where the powdery raw materials are easily clumped together when they come into contact with water and are not easy to disperse, resulting in poor mixing effect of the powdery raw materials during the mixing process.
[0029] The loosening mechanism is used to loosen and mix the raw materials deposited at the bottom of the mixing tank 1. The loosening mechanism includes four rectangular rods 11 that are slidably connected to the lower part of the inner wall of the mixing tank 1 through a sealing seal. Each of the four rectangular rods 11 has a loosening plate 12 fixedly connected to one end of each rod that is close to the other. Figure 5 As shown, the lower ends of the four loosening plates 12 are attached to the bottom of the mixing tank 1. The four loosening plates 12 are symmetrically arranged. The ends of the four rectangular rods 11 that are far apart from each other are all fixedly connected to the moving plates 13. The side walls of the moving plates 13 near the rectangular rods 11 are elastically connected to the side walls of the mixing tank 1 through multiple springs 14.
[0030] Each of the four movable plates 13 has an L-shaped plate 15 fixedly connected to its sidewall away from the rectangular rod 11. The sidewalls of the four L-shaped plates 15 away from the movable plates 13 are slidably connected to the inner wall of the fixed frame 2.
[0031] The vertical rod 3 is fixedly connected to two cams 16 on the side wall inside the fixed frame 2. The two cams 16 are symmetrically arranged, and the side walls of the two cams 16 respectively fit against the side walls of the four L-shaped plates 15 during rotation.
[0032] During the rotation of the vertical rod 3, it will drive the two cams 16 to rotate. At this time, the side walls of the two cams 16 will intermittently fit against the side walls of the two L-shaped plates 15 facing each other. The two L-shaped plates 15 facing each other will move back and forth under the squeezing force of the two cams 16 and the elastic force of multiple springs 14, which will drive the two moving plates 13 facing each other to move back and forth, and drive the two loosening plates 12 facing each other to move back and forth. This will cause the loosening plates 12 to push and loosen the raw materials deposited at the bottom of the mixing tank 1, further improving the mixing quality of the formaldehyde-free putty and preventing the heavier raw materials from easily depositing at the bottom of the mixing tank 1, resulting in poor mixing effect of this part of the raw materials.
[0033] When mixing formaldehyde-free putty with interior wall latex paint, the prepared raw materials are first fed into the mixing tank 1 through the feeding pipe 8. Then, the motor 7 is driven. During the rotation of the motor 7, multiple mixing plates 4 are rotated through the vertical rod 3, which can mix and stir the various raw materials in the mixing tank 1. The rotation of the multiple mixing plates 4 drives multiple first grinding tooth plates 5 to continuously pass over two second grinding tooth plates 6. As the various raw materials flow continuously in the mixing tank 1, the powdery raw materials that are condensed together enter between the first grinding tooth plates 5 and the second grinding tooth plates 6, which can grind and disperse the condensed powdery raw materials, speed up the mixing efficiency of the powdery raw materials, and improve the mixing quality of the formaldehyde-free putty.
[0034] Simultaneously, during the rotation of the vertical rod 3, it will drive the two cams 16 to rotate. At this time, the side walls of the two cams 16 will intermittently fit against the side walls of the two L-shaped plates 15 facing each other. The two L-shaped plates 15 facing each other will move back and forth under the squeezing force of the two cams 16 and the elastic force of multiple springs 14, driving the two moving plates 13 facing each other to drive the two rectangular rods 11 to move back and forth, driving the two loosening plates 12 facing each other to move back and forth, so that the loosening plates 12 push and loosen the raw materials deposited at the bottom of the mixing tank 1, further improving the mixing quality of the formaldehyde-free putty, and avoiding the fact that the heavier raw materials are easy to deposit at the bottom of the mixing tank 1, resulting in poor mixing effect of this part of the raw materials;
[0035] After the putty paste is mixed, open the electric butterfly valve 10 to discharge the putty paste through the discharge pipe 9.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
