Description

Technical Field

[0001] This utility model relates to the field of stone-like paint production technology, and more specifically to a grinding machine for producing stone-like paint. Background Technology

[0002] Stone-look paint is a thick exterior wall coating that closely resembles the decorative effect of marble and granite, primarily used to create a stone-like effect on building exteriors. Once dried and hardened, it becomes very solid, possessing a natural and realistic color that evokes an elegant, harmonious, and dignified aesthetic. Stone-look paint is mainly composed of natural stone powder in various colors, and the manufacturing process typically involves grinding the raw materials using a grinding machine.

[0003] For example, Chinese patent application number CN202323064507.7 discloses a grinding machine for producing imitation stone paint coatings, including a base, a grinding cylinder on the upper part, and hydraulic cylinders on the left and right sides. The top of the grinding cylinder is open and a cylinder cover is attached to it. Lifting plates are fixed to both sides of the cylinder cover, and the piston rod of the hydraulic cylinder is detachably connected to the lifting plate on the same side. This utility model can realize the circulating grinding of materials and the rapid and thorough discharge of the ground material, making it more practical.

[0004] After improvements were made to the grinding machine used for producing imitation stone paint coatings, the material pump can be used to circulate and extract the material, making it convenient to grind the material multiple times. However, during the grinding process of imitation stone paint coatings, it is impossible to sample the material, making it difficult to know the fineness of the material grinding, which needs to be improved.

[0014] 1. This utility model employs a combination of a sampling port, a protective cylinder, a sampling head, a sampling channel, a transparent sampling cylinder, a limiting seat, an annular baffle, and an L-shaped positioning rod. By spirally rotating the protective cylinder and the sampling head, the sampling head moves to the inside of the grinding machine housing.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The grinding machine for producing imitation stone paint coatings involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1:

[0023] like Figure 1-4As shown, a grinding machine for producing imitation stone paint coatings includes a grinding machine housing 1. Feeding hoppers 3 are fixedly installed on both sides of the top of the grinding machine housing 1. A protective cover 31 is provided on the top of the feeding hoppers 3, and the inner wall of the protective cover 31 is threaded onto the top of the outer wall of the feeding hoppers 3. A discharge pipe 15 is fixedly installed in the middle of the bottom of the grinding machine housing 1, and a discharge valve 16 is installed on the discharge pipe 15. A first-order reduction motor 5 is fixedly installed in the middle of the top of the grinding machine housing 1. The output end of the first-order reduction motor 5 extends into the interior of the grinding machine housing 1 and is fixedly installed with a connecting shaft 6. Two grinding heads 7 are fixedly sleeved on the outer wall of the connecting shaft 6. Multiple first-order grinding beads 71 ​​are evenly distributed on the outer wall of the grinding heads 7. Two grinding seats 4 are fixedly connected inside the grinding machine housing 1. A grinding groove 8 is opened in the middle of each of the two grinding seats 4. Multiple second-order grinding beads 81 are evenly distributed on the inner wall of the grinding groove 8. The outer wall of the grinding head 7 is located inside the grinding groove 8, and the gap between the inner wall of the grinding groove 8 and the outer wall of the grinding head 7 gradually decreases from top to bottom.

[0024] In this embodiment, the feeding hopper 3 facilitates the discharge of the imitation stone paint material into the interior of the grinding machine housing 1. By spirally installing the protective cover 31 on the top of the feeding hopper 3, it prevents dust generated during the grinding process from drifting to the outside through the feeding hopper 3. At this time, through the cooperation of the first reduction motor 5 and the connecting shaft 6, the two grinding heads 7 are driven to rotate inside the two grinding grooves 8 to grind the material. Since the gap between the inner wall of the grinding groove 8 and the outer wall of the grinding head 7 gradually decreases from top to bottom, the material will be uniformly ground and dispersed between the grinding head 7 and the grinding groove 8, which can improve the fineness of the material and enhance the grinding effect.

[0025] Example 2:

[0026] like Figure 1-4 As shown, a sampling port 2 is provided on the left side of the bottom of the grinding machine housing 1. A protective cylinder 21 and a sampling head 22 are threadedly connected inside the sampling port 2. The bottom of the sampling head 22 is fixedly connected to the top of the protective cylinder 21. A transparent sampling cylinder 24 is movably connected inside the protective cylinder 21. The top of the transparent sampling cylinder 24 overlaps the bottom of the sampling head 22. Multiple sampling channels 23 are evenly provided inside the sampling head 22. One end of the sampling channel 23 is located on the side wall of the sampling head 22, and the other end of the sampling channel 23 is located at the bottom of the sampling head 22. A limiting seat 25 is threadedly connected to the bottom of the inner cavity of the protective cylinder 21. The bottom of the transparent sampling cylinder 24 overlaps the top of the limiting seat 25. An annular baffle 26 is fixedly connected to the lower part of the outer wall of the protective cylinder 21. Two L-shaped positioning rods 27 are symmetrically fixedly connected to the bottom of the grinding machine housing 1. The two sides of the bottom of the annular baffle 26 overlap the inner walls of the two L-shaped positioning rods 27.

[0027] In this embodiment, the L-shaped positioning rod 27 and the annular baffle 26 facilitate the blocking and limiting of the lower part of the protective cylinder 21, preventing the protective cylinder 21 and the sampling head 22 from moving out of the sampling port 2. By rotating the protective cylinder 21 and the sampling head 22 by screw, the sampling head 22 can be moved upward to the inside of the grinding machine housing 1, and the material is discharged into the transparent sampling cylinder 24 through the sampling channel 23. The transparent sampling cylinder 24 is used to collect the material. Then, the protective cylinder 21 and the sampling head 22 are rotated in the opposite direction, so that the protective cylinder 21 and the sampling head 22 move downward to reset. At this time, the limiting seat 25 is screwed down, and the transparent sampling cylinder 24 moves out from the lower part of the protective cylinder 21, which facilitates the sampling of the ground material. The staff can observe or detect the grinding fineness of the material.

[0028] Example 3:

[0029] like Figure 1-4 As shown, a conveyor cylinder 11 is fixedly installed on the right side of the grinding machine housing 1. A conveyor shaft 13 is provided inside the conveyor cylinder 11. Spiral blades are welded to the outer wall of the conveyor shaft 13. A second geared motor 12 is fixedly installed at the bottom end of the conveyor cylinder 11. The output end of the second geared motor 12 extends into the interior of the conveyor cylinder 11 and is fixedly connected to the bottom end of the conveyor shaft 13. The top end of the conveyor shaft 13 is rotatably connected to the top of the inner wall of the conveyor cylinder 11. A guide pipe 9 is fixedly installed on the right side of the bottom of the grinding machine housing 1. A control valve 10 is installed on the guide pipe 9. One end of the guide pipe 9 is fixedly installed below the left side of the conveyor cylinder 11. An inclined pipe 14 is fixedly connected above the left side of the conveyor cylinder 11. One end of the inclined pipe 14 extends into the upper right side of the interior of the grinding machine housing 1.

[0030] In this embodiment, the material in the lower part of the grinding mill housing 1 is easily discharged into the conveying cylinder 11 by the cooperation of the guide pipe 9 and the control valve 10. The material is driven to move upward inside the conveying cylinder 11 by the cooperation of the second gear motor 12, the conveying shaft 13 and the spiral blades. The material is then discharged back into the upper part of the grinding mill housing 1 through the inclined pipe 14, which facilitates repeated grinding of the material.

[0031] In summary, as Figure 1-4As shown, this grinding machine for producing imitation stone paint coatings is used by first unscrewing the protective cover 31, and then feeding the imitation stone paint material into the grinding seat 4 inside the grinding machine housing 1 through the feeding hopper 3. The protective cover 31 is then screwed back onto the top of the feeding hopper 3. The connecting shaft 6 is then driven to rotate by the first reduction motor 5, which in turn drives the two grinding heads 7 to rotate inside the two grinding grooves 8, grinding the material. After being ground between the two grinding heads 7 and the two grinding grooves 8, the material falls downwards into the lower part of the grinding machine housing 1. If sampling is required, the operator screws the protective cylinder 21, which moves the sampling head 22 upwards into the grinding machine housing 1. The ground material then flows through the sampling channel 23 inside the sampling head 22 into the transparent sampling cylinder 24, where the material is collected. The protective cylinder 24 is then rotated in the opposite direction. The protective cylinder 21 and sampling head 22 are moved downwards, and the protective cylinder 21 drives the annular baffle 26 to move to the inner wall of the L-shaped positioning rod 27, thereby limiting the protective cylinder 21. Then, the limiting seat 25 is screwed down, and the transparent sampling cylinder 24 is moved out from the lower part of the protective cylinder 21 to sample the ground material, so that the staff can observe or test the fineness of the material. If it is necessary to repeat the grinding with the material, the control valve 10 can be opened, and the material in the lower part of the grinding machine housing 1 can be discharged into the inside of the conveying cylinder 11 through the guide pipe 9. The conveying shaft 13 and the spiral blade are driven to rotate by the second gear motor 12, thereby conveying the material. The material is discharged back into the upper part of the grinding machine housing 1 through the inclined pipe 14. At this time, the material can be repeatedly ground in the same way. After grinding, the discharge valve 16 can be opened, and the material can be discharged through the discharge pipe 15.
