Description

Technical Field

[0001] This utility model relates to the field of coating mixing technology, and more specifically, to a raw material mixing device for the production of water-based sand coatings. Background Technology

[0002] Water-in-sand, a sand-textured liquid granite, also known as water-in-sand multicolor paint, is a water-based environmentally friendly exterior wall decorative coating that follows real stone paint and water-in-water multicolor paint. During its processing, a stirring device is generally used to stir the raw materials.

[0003] A search revealed a prior art patent for a raw material mixing device for producing water-based sand coatings, patent publication number CN218573365U. The specification states that a connecting plate and a rotating roller are used to drive a motor to rotate the rotating roller, which in turn drives a second rotating rod to rotate. This rotation, along with the external stirring rods of the rotating roller and the second rotating rod, is used to mix the raw materials. The crisscrossing arrangement of the rotating roller and the external stirring rods of the second rotating rod improves the mixing effect.

[0004] However, in actual use, when mixing raw materials, liquid additives such as thickener solutions and film-forming aid solutions are usually added to the mixing tank to produce coatings with different properties to suit different application scenarios. When adding additives, they are usually poured directly into the mixing tank. Due to the fluidity and surface tension of the liquid, the additives may only flow on the surface or locally in the early stages of mixing, which prevents the additives from being fully mixed with the main raw materials in time. This results in excessively high local concentrations during mixing, thus affecting the production quality of the raw materials. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a raw material mixing device for the production of water-based sand coatings, so as to solve the problem that in the prior art, the auxiliary materials are directly added into the mixing tank, which makes it impossible for the auxiliary materials and raw materials to be fully mixed in time, resulting in excessively high local concentration during mixing, thus affecting the production quality of the raw materials.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a raw material mixing device for the production of water-based sand coatings, comprising a machine body, a mixing shaft rotatably connected to one side of the machine body, a filling groove being provided inside the mixing shaft, a plurality of guide blocks being fixedly connected inside the filling groove, and filter screens being fixedly connected to the adjacent sides of the guide blocks on both the front and rear sides, a movable door being hinged to the upper side of the inner wall of the filling groove, a connecting block being fixedly connected to the left end of the movable door, a connecting groove being provided on the upper side of the inner wall of the mixing shaft, the connecting block being inserted into the inner wall of the connecting groove, a locking groove being provided on the lower side of the inner wall of the connecting groove, a locking block being locked inside the locking groove, and the locking block being slidably connected to the inner wall of the mixing shaft through the connecting block.

[0007] The filter screen is fixedly connected to both the upper and lower sides with limiting blocks. The inner wall of the filling tank is provided with multiple limiting grooves. Every two limiting blocks are respectively engaged in the upper and lower sides of the limiting groove. A filling block is slidably connected to the upper side of the inner wall of the filling tank.

[0009] The mounting groove has a sliding groove on the upper side of its inner wall, a slider is fixedly connected to the top of the pull rod, and an insert is hinged to the front side of the slider.

[0010] The outer side of the filling block is in contact with the inner side of the movable door, and the filter screen is slidably connected to the inner wall of the limiting groove.

[0011] The mounting plate is slidably connected inside the mounting groove, and one side of the pull rod is slidably connected inside the mounting groove.

[0012] One end of the elastic element is fixedly connected to the inner wall of the mounting groove, and the other end of the elastic element is fixedly connected to the mounting plate.

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1: Please refer to Figures 1 to 6This utility model provides a technical solution: a raw material mixing device for the production of water-based sand coatings, including a body 1. A stirring shaft 2 is rotatably connected to one side of the body 1. The body 1 provides installation space for the stirring shaft 2, allowing the stirring shaft 2 to stir the raw materials inside the mixing tank. A filling groove 3 is provided inside the stirring shaft 2. Multiple guide blocks 4 are fixedly connected inside the filling groove 3. The guide blocks 4 are used to guide the liquid auxiliary materials inside the filling groove 3 into the mixing tank. Filter screens 5 are fixedly connected to adjacent sides of the guide blocks 4 on both the front and rear sides, and the filter screens 5 are used to disperse the materials into the mixing tank. The auxiliary materials in the filling tank 3 are used to make the mixing more uniform. The upper inner wall of the filling tank 3 is hinged with a movable door 6. The movable door 6 is used to block the feed inlet of the filling tank 3 so that the auxiliary materials will not leak from the feed inlet of the filling tank 3. The left end of the movable door 6 is fixedly connected to a connecting block 7. The upper inner side of the stirring shaft 2 is provided with a connecting groove 8. The connecting block 7 is inserted into the inside of the connecting groove 8. The lower inner wall of the connecting groove 8 is provided with a slot 9. The slot 9 is fitted with a locking block 10. The locking block 10 passes through the connecting block 7 and is slidably connected to the inside of the stirring shaft 2. The locking block 10 is used to limit the movable door 6.

[0026] When it is necessary to stir the raw materials inside the mixing tank, the filter screen 5 is slid into the inner wall of the filling tank 3, allowing the guide block 4 to enter the filling tank 3. At this time, the stirring shaft 2 is moved into the mixing tank, and then the locking block 10 is pulled upwards, allowing the locking block 10 to disengage from the slot 9 and the connecting block 7. Then the movable door 6 is opened, allowing the auxiliary materials to be added into the filling tank 3. After the addition is completed, the movable door 6 is closed, allowing the connecting block 7 to slide into the connecting slot 8, and the locking block 10 is moved downwards, allowing the locking block 10 to penetrate the connecting block 7 and engage with the slot 9. At this time, the stirring shaft 2 can be rotated to stir the raw materials, allowing the auxiliary materials to be injected into the raw materials at multiple points continuously. As the stirring shaft 2 rotates, the materials are dispersed in time, resulting in high uniformity of the addition of auxiliary materials and thus high production quality.

[0027] Example 2: Based on Example 1, in order to achieve more stable installation of filter screen 5, limiting blocks 12 are fixedly connected to both the upper and lower sides of filter screen 5. Multiple limiting grooves 11 are opened on the inner wall of filling tank 3. Filter screen 5 is slidably connected to the inner wall of limiting groove 11. Limiting groove 11 provides installation space for filter screen 5. Each pair of limiting blocks 12 are respectively engaged in the upper and lower sides of the inside of limiting groove 11, so that filter screen 5 can be limited by limiting blocks 12, thereby making the installation stability of filter screen 5 higher. A filling block 20 is slidably connected to the upper side of the inner wall of filling tank 3. The filling block 20 is used to guide and filter the auxiliary materials entering the filling tank 3, so as to provide the mixing quality. The outside of filling block 20 is in contact with the inside of movable door 6. Movable door 6 is used to limit filling block 20, so that it can be stably installed inside filling tank 3.

[0028] When the filter screen 5 needs to be installed, the filter screen 5 is slid into the limiting groove 11, so that the limiting block 12 can slide into the limiting groove 11, thereby limiting the filter screen 5 and allowing the filter screen 5 to be installed stably.

[0029] Example 3: Based on Example 2, in order to facilitate the pulling of the locking block 10, an installation groove 13 is provided on the upper side of the inner wall of the connecting groove 8. The top of the locking block 10 is fixedly connected to the mounting piece 14. The mounting piece 14 is slidably connected inside the installation groove 13. The installation groove 13 limits the mounting piece 14 so that the mounting piece 14 will not deviate when sliding. The top of the mounting piece 14 is fixedly connected to the pull rod 15. One side of the pull rod 15 is slidably connected inside the installation groove 13. The installation groove 13 limits the pull rod 15 so that the pull rod 15 can slide smoothly. An elastic element 16 is sleeved on the outside of the pull rod 15. One end of the elastic element 16 is fixedly connected to the inner wall of the installation groove 13, and the other end of the elastic element 16 is fixedly connected to the mounting piece 14.

[0030] When the locking block 10 needs to be pulled, the pull rod 15 is pulled upward, causing the mounting piece 14 to move upward. This causes the mounting piece 14 to pull the locking block 10 upward, and the mounting piece 14 to compress the elastic element 16, causing deformation. This allows the locking block 10 to disengage from the slot 9 and the interior of the connecting block 7. Conversely, by releasing the pull rod 15, the elastic element 16 is reset, causing it to push the mounting piece 14 downward, allowing the mounting piece 14 to penetrate the interior of the connecting block 7 and the slot 9 and engage.

[0031] Example 4: Based on Example 3, in order to facilitate the pulling of the pull rod 15, a sliding groove 19 is provided on the upper side of the inner wall of the mounting groove 13. The other end of the pull rod 15 is slidably connected to the inside of the sliding groove 19. The sliding groove 19 limits the pull rod 15 so that the pull rod 15 will not deviate when moving. A slider 17 is fixedly connected to the top of the pull rod 15. The slider 17 is slidably connected to the inside of the sliding groove 19. The sliding groove 19 limits the slider 17 so that the slider 17 can slide smoothly. An insert 18 is hinged to the front side of the slider 17. The insert 18 is inserted into the stirring shaft 2 and is used to limit the slider 17.

[0032] When it is necessary to pull the lever 15, the insert block 18 is snapped off, allowing the insert block 18 to disengage from the inside of the stirring shaft 2, thereby freeing the slider 17 from restriction. Then, the slider 17 is pulled upward, causing the lever 15 to move upward.

[0033] The working process of this utility model is as follows:

[0034] When additives are needed during mixing, the filter screen 5 is slid into the limiting groove 11, allowing the limiting block 12 to slide into the limiting groove 11, thus limiting the filter screen 5 and ensuring its stable installation. Then, by engaging the insert block 18, it disengages from the mixing shaft 2, freeing the slider 17 from restriction. Pulling the slider 17 upwards causes the pull rod 15 to move upwards, which in turn pulls the mounting plate 14 upwards. This, in turn, causes the mounting plate 14 to pull the locking block 10 upwards, compressing the elastic element 16 and causing deformation. This allows the locking block 10 to disengage from the slot 9 and the connecting block 7. At this point, the movable door 6 is opened, allowing the filling block 20 to... The material is exposed to the outside, and auxiliary materials are added into the filling tank 3 through the filling block 20. The filling block 20 filters the auxiliary materials, resulting in high-quality auxiliary materials added into the mixing tank. After the addition is completed, the connecting block 7 slides into the connecting groove 8 by closing the movable door 6. The elastic element 16 is reset by releasing the pull rod 15, which pushes the mounting plate 14 downward. The mounting plate 14 passes through the connecting block 7 and engages with the slot 9, allowing the movable door 6 to close stably. At this time, the stirring shaft 2 can be rotated to stir the raw materials, allowing the auxiliary materials to be injected into the raw materials from multiple points continuously. As the stirring shaft 2 rotates, the materials are dispersed in time, resulting in high uniformity of the addition of auxiliary materials and thus high production quality.
