DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figure 1 - Fig. 9 As shown, a preparation device for 6D high-quality water-based multi-color paint includes a grinding machine body 1, a rear roller 4 is arranged at the rear of the grinding machine body 1, a middle roller 7 is arranged at the front of the rear roller 4, a front roller 8 is arranged at the front of the middle roller 7, a storage plate 2 is fixedly connected at the bottom of the front roller 8, the middle roller 7 and the rear roller 4, a discharging plate 3 is fixedly connected to the front of the storage plate 2, and an adjustment structure 5 is arranged on the side of the grinding machine body 1;

[0033] The adjustment structure 5 includes two sliding plates 12, and adjustment grooves 9 are penetrated on both sides of the grinding body 1. The front roller 8, the middle roller 7 and the rear roller 4 are respectively located inside the two adjustment grooves 9 and are fixedly connected with sliding shafts 10. A fixed plate 11 is fixedly connected to the front and rear parts of the adjustment groove 9 on one side of the grinding body 1, and a fixed plate 11 is also fixedly connected to the middle of the adjustment groove 9 on one side of the grinding body 1. A sliding plate 12 is slidably connected to one side of the grinding body 1 and between two adjacent fixed plates 11. An adjustment screw rod 16 is rotatably connected between two adjacent fixed plates 11 and near the top. A guide rod 15 is fixedly connected between two adjacent fixed plates 11 and near the bottom. The sides of the two sliding plates 12 are respectively fixedly connected with motor 13 and motor 2 14. The two adjustment screw rods 16 penetrate the middle fixed plate 11 and are fixedly connected to each other.

[0034] In actual operation, the raw materials for preparing 6D high-quality water-based multi-color paint are first slowly added between the rear roller 4 and the middle roller 7, the rear roller 4 is started and rotated counterclockwise at a slower speed, and the materials are brought into the grinding area with the middle roller 7. The middle roller 7 rotates clockwise at a moderate speed, and cooperates with the rear roller 4 to perform preliminary extrusion and grinding of the materials, so that the materials are initially crushed and mixed. The materials after preliminary grinding are transferred by the middle roller 7 to the grinding area between the front roller 8 and the middle roller 7, and the front roller 8 rotates clockwise at a faster speed to further refine and homogenize the materials. At the same time, the materials are fully mixed under the action of high-speed shearing and extrusion, and then the ground raw materials are conveyed by the front roller 8 and discharged along the discharge plate 3.

[0035] Specifically, by starting the adjustment structure 5, the spacing between the front roller 8, the middle roller 7 and the rear roller 4 can be adjusted. When the spacing becomes larger, materials with larger particles can be ground, and when the spacing becomes smaller, materials with smaller particles can be ground. The operating steps of the adjustment structure 5 are to rotate the adjustment screw 16 at the front by a hand wheel, thereby driving the adjustment screw 16 at the rear to rotate together. Since the two adjustment screws 16 are symmetrical to each other, the two adjustment screws 16 rotate synchronously, which can drive the two sliding plates 12 along the two guide rods 15 and in the direction away from each other, and then slide away from each other along the adjustment groove 9 through the two sliding shafts 10 at the front and rear parts of one side, thereby driving the front roller 8 and the rear roller 4 to move away from each other, thereby completing the adjustment of the spacing between the front roller 8, the middle roller 7 and the rear roller 4.

[0036] In this embodiment, the output shaft of motor 13 passes through the sliding plate 12 near the front and is fixedly connected to one end of the sliding shaft 10 near the front of one side, and the output shaft of motor 2 14 passes through the sliding plate 12 near the rear and is fixedly connected to one end of the sliding shaft 10 near the rear of one side.

[0037] Specifically, the first starter motor 13 drives the sliding shaft 10 near the front of one side to rotate, thereby driving the front roller 8 to rotate, and the second starter motor 14 drives the sliding shaft 10 near the rear of one side to rotate, thereby driving the rear roller 4 to rotate.

[0038] In this embodiment, one end of the sliding shaft 10 in the middle of one side passes through the side of the adjustment groove 9 on one side and is rotatably connected to the fixed plate 11 in the middle. The two adjusting screw rods 16 are symmetrical front and back along the fixed plate 11 in the middle. The two sliding plates 12 are respectively threadedly connected to the two adjusting screw rods 16, and the two guide rods 15 pass through the two sliding plates 12 respectively.

[0039] In this embodiment, a transmission structure 17 is set on the other side of the grinding machine body 1, and the transmission structure 17 includes two main gears 18 and a connecting gear 19. One ends of the two sliding shafts 10 near the front and middle of the other side pass through the adjustment groove 9 near the other side and are fixedly connected to the two main gears 18. The connecting gear 19 is located between the two main gears 18. An arc groove 21 is opened on the other side of the grinding machine body 1. One side of the connecting gear 19 is rotatably connected to a connecting shaft 20. The connecting gear 19 is slidably connected to the arc groove 21 through the connecting shaft 20. One end of the sliding shaft 10 near the rear of the other side passes through the adjustment groove 9 near the other side and is fixedly connected to a limit block 35 located on the other side of the grinding machine body 1.

[0040] The transmission structure 17 is started, so that the motor 13 drives the front roller 8 to rotate while driving the middle roller 7 to rotate together, and the rotation directions of the front roller 8 and the middle roller 7 are the same. The specific operation steps of the transmission structure 17 are as follows: when the motor 13 drives the front roller 8 to rotate, the main gear 18 at the front is driven to rotate together through the sliding shaft 10 at the front of the other side, and then the main gear 18 at the rear is driven to rotate together through the transmission of the connecting gear 19, and the rotation directions of the two main gears 18 are consistent. The main gear 18 at the rear rotates, and the middle roller 7 is driven to rotate through the sliding shaft 10 in the middle of the other side. Since the meshing friction will cause energy loss, the transmission efficiency of the gear system is reduced. Therefore, when the main gear 18 at the rear is driven to rotate together through the main gear 18 at the front, the speed of the main gear 18 at the front is faster than that of the main gear 18 at the rear, that is, the speed of the front roller 8 is higher than that of the middle roller 7, which is consistent with the principle that the front roller 8 has the fastest speed, the middle roller 7 has the second fastest speed, and the rear roller 4 has the slowest speed in the grinding step.

[0041] When the spacing between the front roller 8 and the middle roller 7 is adjusted by the adjustment structure 5, the connecting shaft 20 is slid along the arc groove 21 to squeeze and adjust the position of the connecting gear 19, so that the connecting gear 19 can still mesh with the two main gears 18 at the same time even when the position of the front roller 8 changes, thereby allowing the front roller 8 and the middle roller 7 to still rotate synchronously.

[0042] In this embodiment, the interior of the connecting shaft 20 passes through the connecting gear 19 and is threadedly connected to a rotating rod 22. A through groove is provided inside the connecting shaft 20 near one end and through the outer surface. The interior of the through groove passes through the outer surface of the connecting shaft 20 and is symmetrically slidably connected with two clamping blocks 24. A clamping groove 23 is provided inside the grinding body 1 and is located inside the arc groove 21. An extrusion groove 25 is provided between the two clamping blocks 24 and passes through them together. The extrusion groove 25 is in the shape of a truncated cone. The diameter of one side of the extrusion groove 25 is larger than the diameter of the rotating rod 22, and the diameter of the other side of the extrusion groove 25 is smaller than the diameter of the rotating rod 22.

[0043] Specifically, after adjusting the position of the connecting gear 19 along the arc groove 21, the rotating rod 22 is rotated so that the rotating rod 22 moves forward along one end of the connecting shaft 20, and then squeezes the two blocks 24 at the same time through the extrusion groove 25. Since the extrusion groove 25 is in a truncated cone shape, the diameter of one side of the extrusion groove 25 is larger than the diameter of the rotating rod 22, and the diameter of the other side of the extrusion groove 25 is smaller than the diameter of the rotating rod 22. Therefore, when the rotating rod 22 moves forward to squeeze the two blocks 24, the two blocks 24 will slide away from each other along the through groove until the two blocks 24 are respectively engaged with the top and bottom of the slot 23, the connecting shaft 20 can be fixed inside the arc groove 21, thereby fixing the position of the connecting gear 19. Moreover, since the rotating rod 22 is threadedly connected to the connecting shaft 20, and the threaded connection has self-locking ability, the rotating rod 22 squeezes the two blocks 24, so that the two blocks 24 can be firmly engaged with the slot 23.

[0044] In this embodiment, the two blocks 24 are adaptively matched with the top and bottom of the slot 23 respectively, and one end of the front adjusting screw rod 16 passes through the front part of the front fixing plate 11 and is fixedly connected with a hand wheel.

[0045] In this embodiment, a pair of fixing blocks 26 are fixedly connected to both sides of the top of the grinding machine body 1 , and a cleaning screw 27 is rotatably connected between each pair of fixing blocks 26 .

[0046] In this embodiment, a cleaning structure 6 is provided at the front and rear parts of the top of the grinding machine body 1, and the cleaning structure 6 includes three movable plates 28. Two cleaning screws 27 respectively penetrate the front part of the movable plate 28 at the front part, and the two cleaning screws 27 respectively threadedly penetrate the two movable plates 28 at the rear part. The adjacent surfaces of two adjacent movable plates 28 are rotatably connected with connecting plates 29, and the two adjacent connecting plates 29 are rotatably connected to each other. The bottom of each connecting plate 29 is fixedly connected with a horizontal nozzle group 30, and the bottom of each connecting plate 29 is fixedly connected with a vertical nozzle group 31 on both sides.

[0047] The thread of the cleaning screw 27 is composed of two mutually symmetrical thread grooves, so the lines of the two thread grooves are opposite.

[0048] Specifically, the horizontal nozzle group 30 and the vertical nozzle group 31 are connected to the external water injection hose, and the two cleaning structures 6 are started, and then the adjustment structure 5 is coordinated to clean the surfaces of the front roller 8, the middle roller 7 and the rear roller 4. The specific steps are as follows: then the two cleaning screws 27 are rotated to drive the four moving plates 28 in the middle to slide in the direction of approaching each other, thereby driving all the connecting plates 29 to be pulled and rotated until all the connecting plates 29 are in a horizontal state. At this time, all the horizontal nozzle groups 30 are facing the front roller 8, middle roller 7, rear roller 4, storage plate 2 and discharge plate 3. At this time, the transverse nozzle group 30 can be used to flush and clean the surfaces of the front roller 8, middle roller 7, rear roller 4, storage plate 2 and discharge plate 3, and the spacing between the front roller 8, middle roller 7 and rear roller 4 is adjusted to the maximum state through the adjustment structure 5. At this time, when flushing them, the gaps between the front roller 8, middle roller 7 and rear roller 4 can be flushed together to avoid the situation where the gaps between the front roller 8, middle roller 7 and rear roller 4 are too small, resulting in ineffective flushing.

[0049] The vertical nozzle group 31 can flush the two side surfaces inside the grinding body 1 , thereby avoiding the situation where the horizontal nozzle group 30 cannot effectively flush the two side surfaces inside the grinding body 1 .

[0050] After cleaning is completed, the two cleaning screws 27 are rotated in the opposite direction to fold and store the movable plate 28 and the connecting plate 29, thereby not affecting the grinding of the raw materials.

[0051] In this embodiment, the front part of the fixed block 26 on the front side is fixedly connected to a motor 32, the output shaft of the motor 32 passes through the fixed block 26 on the front side and is fixedly connected to the cleaning screw rod 27 on the side, the rear parts of the two fixed blocks 26 on the rear side are rotatably connected to pulleys 33, a belt 34 is provided between the two pulleys 33, and the rear parts of the two cleaning screw rods 27 respectively pass through the rear parts of the two fixed blocks 26 on the rear side and are fixedly connected to the two pulleys 33 respectively.

[0052] Specifically, the motor 32 is started to drive the cleaning screw 27 on one side to rotate, and then drive the pulley 33 on one side to rotate, and then through the belt 34, the two pulleys 33 can be driven to rotate synchronously, and then the two cleaning screws 27 can be driven to rotate synchronously, and then the two cleaning structures 6 can be driven to operate synchronously.

[0053] It should be noted that the present invention is a preparation device for a 6D high-quality water-based multi-color paint. When in use, the preparation raw materials of the 6D high-quality water-based multi-color paint are first slowly added between the rear roller 4 and the middle roller 7, the rear roller 4 is started and rotated counterclockwise at a slower speed, and the material is brought into the grinding area with the middle roller 7. The middle roller 7 rotates clockwise at a moderate speed, and cooperates with the rear roller 4 to perform preliminary extrusion and grinding of the material, so that the material is preliminarily crushed and mixed. The preliminarily ground material is transferred by the middle roller 7 to the grinding area between the front roller 8 and the middle roller 7, and the front roller 8 rotates clockwise at a faster speed to further refine and homogenize the material, and at the same time, the material is fully mixed under the action of high-speed shearing and extrusion, and then the ground raw materials will be transported by the front roller 8 and discharged along the discharge plate 3.

[0054] Specifically, by starting the adjustment structure 5, the spacing between the front roller 8, the middle roller 7 and the rear roller 4 can be adjusted. When the spacing becomes larger, materials with larger particles can be ground, and when the spacing becomes smaller, materials with smaller particles can be ground. The operating steps of the adjustment structure 5 are to rotate the adjustment screw 16 at the front by a hand wheel, thereby driving the adjustment screw 16 at the rear to rotate together. Since the two adjustment screws 16 are symmetrical to each other, the two adjustment screws 16 rotate synchronously, which can drive the two sliding plates 12 along the two guide rods 15 and in the direction away from each other, and then slide away from each other along the adjustment groove 9 through the two sliding shafts 10 at the front and rear parts of one side, thereby driving the front roller 8 and the rear roller 4 to move away from each other, thereby completing the adjustment of the spacing between the front roller 8, the middle roller 7 and the rear roller 4.

[0055] Specifically, the first starter motor 13 drives the sliding shaft 10 near the front of one side to rotate, thereby driving the front roller 8 to rotate, and the second starter motor 14 drives the sliding shaft 10 near the rear of one side to rotate, thereby driving the rear roller 4 to rotate. The transmission structure 17 is started, so that the motor 13 drives the front roller 8 to rotate while driving the middle roller 7 to rotate together, and the rotation directions of the front roller 8 and the middle roller 7 are the same. The specific operation steps of the transmission structure 17 are as follows: when the motor 13 drives the front roller 8 to rotate, the main gear 18 at the front is driven to rotate together through the sliding shaft 10 at the front of the other side, and then the main gear 18 at the rear is driven to rotate together through the transmission of the connecting gear 19, and the rotation directions of the two main gears 18 are consistent. The main gear 18 at the rear rotates, and the middle roller 7 is driven to rotate through the sliding shaft 10 in the middle of the other side. Since the meshing friction will cause energy loss, the transmission efficiency of the gear system is reduced. Therefore, when the main gear 18 at the rear is driven to rotate together through the main gear 18 at the front, the speed of the main gear 18 at the front is faster than that of the main gear 18 at the rear, that is, the speed of the front roller 8 is higher than that of the middle roller 7, which is consistent with the principle that the front roller 8 has the fastest speed, the middle roller 7 has the second fastest speed, and the rear roller 4 has the slowest speed in the grinding step.

[0056] When the spacing between the front roller 8 and the middle roller 7 is adjusted by the adjustment structure 5, the connecting shaft 20 is slid along the arc groove 21 to squeeze and adjust the position of the connecting gear 19, so that the connecting gear 19 can still mesh with the two main gears 18 at the same time even when the position of the front roller 8 changes, thereby allowing the front roller 8 and the middle roller 7 to still rotate synchronously.

[0057] Specifically, after adjusting the position of the connecting gear 19 along the arc groove 21, the rotating rod 22 is rotated so that the rotating rod 22 moves forward along one end of the connecting shaft 20, and then squeezes the two blocks 24 at the same time through the extrusion groove 25. Since the extrusion groove 25 is in a truncated cone shape, the diameter of one side of the extrusion groove 25 is larger than the diameter of the rotating rod 22, and the diameter of the other side of the extrusion groove 25 is smaller than the diameter of the rotating rod 22. Therefore, when the rotating rod 22 moves forward to squeeze the two blocks 24, the two blocks 24 will slide away from each other along the through groove until the two blocks 24 are respectively engaged with the top and bottom of the slot 23, the connecting shaft 20 can be fixed inside the arc groove 21, thereby fixing the position of the connecting gear 19. Moreover, since the rotating rod 22 is threadedly connected to the connecting shaft 20, and the threaded connection has self-locking ability, the rotating rod 22 squeezes the two blocks 24, so that the two blocks 24 can be firmly engaged with the slot 23.

[0058] The thread of the cleaning screw 27 is composed of two mutually symmetrical thread grooves, so the lines of the two thread grooves are opposite.

[0059] Specifically, the horizontal nozzle group 30 and the vertical nozzle group 31 are connected to the external water injection hose, and the two cleaning structures 6 are started, and then the adjustment structure 5 is coordinated to clean the surfaces of the front roller 8, the middle roller 7 and the rear roller 4. The specific steps are as follows: then the two cleaning screws 27 are rotated to drive the four moving plates 28 in the middle to slide in the direction of approaching each other, thereby driving all the connecting plates 29 to be pulled and rotated until all the connecting plates 29 are in a horizontal state. At this time, all the horizontal nozzle groups 30 are facing the front roller 8, middle roller 7, rear roller 4, storage plate 2 and discharge plate 3. At this time, the transverse nozzle group 30 can be used to flush and clean the surfaces of the front roller 8, middle roller 7, rear roller 4, storage plate 2 and discharge plate 3, and the spacing between the front roller 8, middle roller 7 and rear roller 4 is adjusted to the maximum state through the adjustment structure 5. At this time, when flushing them, the gaps between the front roller 8, middle roller 7 and rear roller 4 can be flushed together to avoid the situation where the gaps between the front roller 8, middle roller 7 and rear roller 4 are too small, resulting in ineffective flushing.

[0060] The vertical nozzle group 31 can flush the two side surfaces inside the grinding body 1 , thereby avoiding the situation where the horizontal nozzle group 30 cannot effectively flush the two side surfaces inside the grinding body 1 .

[0061] After cleaning is completed, the two cleaning screws 27 are rotated in the opposite direction to fold the movable plate 28 and the connecting plate 29, so that the grinding of the raw material will not be affected. Specifically, the motor 32 is started to drive the cleaning screw 27 on one side to rotate, and then drive the pulley 33 on one side to rotate, and then through the belt 34, the two pulleys 33 can be driven to rotate synchronously, and then the two cleaning screws 27 are driven to rotate synchronously, and then the two cleaning structures 6 are driven to operate synchronously.
