Description

Technical Field

[0001] This utility model relates to the field of coating grinding and dispersion technology, and in particular to a coating grinding and dispersion device. Background Technology

[0002] Paint, or varnish as we commonly refer to it, is just one type. It refers to a class of liquid or solid materials that, when applied to the surface of an object, form a thin film under certain conditions to provide protection, decoration, or other special functions (insulation, rust prevention, mildew prevention, heat resistance, etc.). Paint has a wide range of applications. Paint used in the construction field is called architectural coating. Before use, the components usually need to be mixed and stirred, thoroughly dispersed, and ground to ensure there are no particles or lumps before application, thus ensuring the quality of the paint.

[0003] The existing coating dispersion and grinding process uses two machines. First, the coating raw materials are ground by the grinding equipment. However, most existing grinding equipment is manually ground. This grinding method increases the workload and difficulty of operation for workers. Manual grinding is time-consuming and labor-intensive, resulting in low grinding efficiency and uneven particle size of the ground feed. Furthermore, the various components in the ground powder are prone to clumping or uneven distribution, which has a significant impact on the quality of the subsequent paint coatings. Utility Model Content

[0004] The purpose of this invention is to solve the technical problems existing in the prior art and to provide a coating grinding and dispersing device.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: a coating grinding and dispersing device, comprising a housing, a first motor and a feed pipe disposed on the housing, a pre-drying component disposed inside the feed pipe, a sieve plate disposed inside the housing, a sieve plate having sieve holes disposed on the sieve plate, a reciprocating grinding component disposed above the sieve plate, the reciprocating grinding component including a lead screw rotatably connected to the sieve plate, a sliding sleeve threadedly connected to the lead screw, connecting rods hinged to both sides of the sliding sleeve, a grinding roller connected to the end of the connecting rod, the grinding roller being rotatably connected to the sieve plate, the lead screw being connected to the output end of the first motor, a partition plate disposed inside the housing, forming a dispersion chamber between the partition plate and the sieve plate, a dispersion component disposed inside the dispersion chamber, the dispersion component including a rotating shaft, a dispersion disc and a spiral roller, the rotating shaft being laterally rotatably disposed in the upper dispersion chamber, and multiple dispersion discs being spaced apart along its length on the rotating shaft, a spiral roller being disposed on the rotating shaft between adjacent dispersion discs, a second motor disposed on the outer wall of the housing, the second motor being connected to the rotating shaft, and a discharge port disposed on the partition plate.

[0006] Preferably, the pre-drying component includes multiple sets of guide plates on the feed pipe wall, the guide plates are inclined and staggered, and heating tubes are fixed inside the guide plates.

[0007] Preferably, the spiral roller includes a roller body fixedly sleeved on a rotating shaft, the roller body being provided with spiral strips distributed along its peripheral surface; the peripheral surface of the roller body is also provided with uniformly distributed dispersed protrusions.

[0008] Preferably, two adjacent dispersion discs are connected by multiple sets of fixed shafts parallel to the rotation axis. The multiple sets of fixed shafts are evenly arranged around the rotation axis at the circumferential edge of the dispersion discs, and each fixed shaft is provided with a stirring plate.

[0009] Preferably, a recycling box and a finished product box are provided at the bottom of the housing, and a filter screen is provided above the finished product box. The filter screen is directly below the discharge port, and the filter screen is set at an angle with the lower end of the filter screen closest to the finished product box.

[0010] Preferably, the sieve plate is also provided with a guide rod, and the sliding sleeve is slidably connected to the guide rod.

[0011] The beneficial effects of this utility model are:

[0012] This invention utilizes the combined action of a first motor, lead screw, sliding sleeve, grinding roller, and sieve plate to enable the grinding roller to roll left and right, grinding the coating raw materials. This greatly improves grinding efficiency, allows the coating raw materials to be repeatedly ground to the required particle size, and ensures good grinding uniformity as the particles fall through the sieve plate. Compared with ordinary grinding, this invention provides a better grinding effect and reduces the labor intensity of workers.

[0013] The multiple dispersion discs in the dispersion chamber of this invention can increase the contact rate between the coating raw material and the dispersion discs, and perform multiple dispersions, thereby improving the dispersion rate and dispersion effect. Furthermore, the dispersion protrusions on the spiral roller further disperse the coating raw material, while the stirring plate can stir the coating raw material in the dispersion chamber, further enhancing the dispersion effect. As a result, the dispersion effect and dispersion efficiency of the ground coating raw material in this invention are higher. Attached Figure Description

[0024] Reference Figures 1-3 According to a preferred embodiment of the present invention, a coating grinding and dispersing device includes a housing 1, on which a first motor 5 and a feed pipe 4 are provided. A pre-drying component is provided inside the feed pipe 4. The pre-drying component includes multiple sets of guide plates 23 on the wall of the feed pipe 4. The guide plates 23 are inclined and staggered. A heating tube 24 is fixed inside the guide plate 23. Preferably, the heating tube 24 is an electric heating tube and is electrically connected to an external power source.

[0025] Specifically, the raw material is fed into the feed pipe 4 and falls into the guide plate 23 inside the feed pipe 4. At this time, the heating pipe 24 is connected to conduct electricity. The heat emitted by the heating pipe 24 dries the raw material on the guide plate 23. The guide plate 23 is inclined and staggered, thereby extending the drying time of the coating raw material, making the coating raw material dry more thoroughly, ensuring the drying efficiency of the coating raw material, and ensuring the grinding quality of the coating raw material.

[0026] In this embodiment, a sieve plate 2 is provided inside the housing 1, and sieve holes 3 are provided on the sieve plate 2. A reciprocating grinding assembly is provided above the sieve plate 2. The reciprocating grinding assembly includes a lead screw 6 rotatably connected to the sieve plate 2, a sliding sleeve 7 threadedly connected to the lead screw 6, connecting rods 8 hinged to both sides of the sliding sleeve 7, and a grinding roller 9 connected to the end of the connecting rod 8. The grinding roller 9 is tumbledly connected to the sieve plate 2. The lead screw 6 is connected to the output end of the first motor 5. Preferably, the first motor 5 is a forward and reverse motor.

[0027] Furthermore, a guide rod 25 is also provided on the sieve plate 2, and the sliding sleeve 7 is slidably connected to the guide rod 25.

[0028] Specifically, during use, the dried paint material falls onto the sieve plate 2, and then the first motor 5 is started. The first motor 5 rotates forward and backward, driving the lead screw 6 to rotate. The lead screw 6 drives the sliding sleeve 7 to move back and forth in the vertical direction. The sliding sleeve 7 drives the grinding roller 9 to move back and forth on the surface of the sieve plate 2 through the connecting rod 8. This allows the grinding roller 9 to roll left and right to grind the paint material, greatly improving the grinding efficiency. It can repeatedly grind the paint material to the required particle size, and the material falls through the sieve plate 2. The grinding uniformity is good. Compared with ordinary grinding, its grinding effect is better, and it reduces the labor intensity of the workers.

[0029] In this embodiment, a partition 15 is also provided inside the housing 1, and a dispersion cavity is formed between the partition 15 and the sieve plate 2. A dispersion assembly is provided inside the dispersion cavity. The dispersion assembly includes a rotating shaft 11, a dispersion disk 12 and a spiral roller 14. The rotating shaft 11 is rotatably arranged in the upper dispersion cavity, and a plurality of dispersion disks 12 are spaced apart along its length direction on the rotating shaft 11. A spiral roller 14 is provided on the rotating shaft 11 between adjacent dispersion disks 12. A second motor 10 is provided on the outer wall of the housing 1. The second motor 10 is connected to the rotating shaft 11. A discharge port 16 is provided on the partition 15.

[0030] Furthermore, the spiral roller 14 includes a roller body 20 fixedly sleeved on the rotating shaft 11, the roller body 20 is provided with spiral strips 21 distributed along its peripheral surface; the peripheral surface of the roller body 20 is also provided with uniformly distributed dispersed protrusions 22.

[0031] Furthermore, multiple sets of fixed shafts parallel to the rotating shaft 11 are connected between two adjacent dispersion discs 12. The multiple sets of fixed shafts are evenly arranged around the rotating shaft 11 at the circumferential edge of the dispersion disc 12, and each fixed shaft is provided with a stirring plate 13.

[0032] Specifically, after the ground coating material falls into the dispersion chamber, it undergoes multiple dispersions by passing through several dispersion discs 12. During these multiple dispersions, the spiral roller 14 pushes some of the coating material from one dispersion disc 12 to the next, thus increasing the dispersion rate. This also allows the coating material to be pushed further into the dispersion chamber and dispersed by more discs 12, increasing the contact rate with the next disc and further improving the dispersion rate and effect. As the coating material is pushed by the spiral roller 14, it is further dispersed by the dispersion protrusions on the roller 14, resulting in faster dispersion. Furthermore, the rotation of the rotating shaft 11 causes the stirring plate 13 to rotate, thus agitating the coating material in the dispersion chamber and enhancing the dispersion effect.

[0033] In this embodiment, a recycling box 19 and a finished product box 18 are provided at the bottom of the housing 1. A filter screen 17 is provided above the finished product box 18. The filter screen 17 is directly below the discharge port 16. The filter screen 17 is inclined and the direction of the filter screen 17 closest to the finished product box 18 is the lower end.

[0034] Specifically, after grinding and dispersing, the paint raw materials fall into the filter screen 16 through the discharge port on the partition 15. Paint raw material particles with qualified particle size pass through the filter screen 16 and enter the finished product box 18, while paint raw material particles with unqualified particle size slide from the filter screen 16 into the recycling box 19. The paint raw material particles in the recycling box 19 are then added back into the feed pipe 4 for further processing.

[0035] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.

[0036] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
