Description

Technical Field

[0001] The utility model relates to the field of coatings, in particular to a grinding device for research and development of architectural coatings. Background Art

[0002] The material that can be coated on the surface of an object and can bond well with the base material to form a complete and tough protective film is called architectural coating. Coating and paint are the same concept. Paint is a customary name that people have used for a long time. After being introduced into my country, it has been used in the construction industry. The role of coating can be summarized into three aspects: protective role, decorative role, and special functional role. The general composition of coating: including film-forming substances, pigments and fillers, solvents, and additives.

[0003] Membrane materials and pigments are generally in powder form, and solvents are generally liquid. Whether the paint is applied evenly and finely mainly depends on the coarseness of the membrane material and pigments. The finer the membrane material and pigments, the more even and dense the application, and the better the effect. Existing grinding devices for paint research and development mainly use one or two grinding rollers for grinding. The ground powder easily sticks to the surface of the grinding device, and the R&D personnel need to manually clean it, which increases their workload. At the same time, during manual cleaning, the dust raised is easily absorbed by the human body, which can easily damage human health.

[0004] Therefore, in order to solve the above problems, a grinding device for developing architectural coatings with a cleaning function is specially designed. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] A grinding device for the research and development of architectural coatings, such as Figure 1-Figure 8As shown, it includes a lower hopper 1, a grinding barrel 2, a limiting ring 3, a support leg 4, a support shell 5, a drive motor 6, a rotating shaft 7, a grinding roller 8, a transmission assembly 9, a protective shell 10, a grinding cone 11, a connecting rod 12, a driven gear 13, a double-axis motor 14, a transmission gear 15, a crushing wheel 16, a scraper rod 17, a lower ring 18 and a protective shell 28. A grinding barrel 2 is installed at the bottom of the lower hopper 1, a limiting ring 3 is sleeved on the outer side of the bottom of the grinding barrel 2, and a support leg 4 is installed on the side of the limiting ring 3. The support leg 4 is in contact with the ground and plays a supporting role. A grinding roller 8 is symmetrically and rotatably arranged at the bottom of the lower hopper 1, and both ends of the grinding roller 8 are connected to the rotating shaft 7, and the rotating shaft 7 is rotatably connected to the lower hopper 1. A support shell 5 is arranged on the side of the grinding barrel 2, and a drive motor 6 is installed in the support shell 5. The output shaft of the drive motor 6 is connected to one of the rotating shafts 7 through a coupling, and one end of the rotating shaft 7 is sleeved with a transmission assembly 9. Protective shells 10 are installed at both ends of the grinding roller 8. A grinding cone 11 is rotatably arranged in the grinding barrel 2. A double-axis motor 14 is installed on the side of the limit ring 3. The downward output shaft of the double-axis motor 14 is connected to a transmission gear 15 through a coupling. A connecting rod 12 is installed on the outside of the grinding barrel 2. A driven gear 13 is sleeved on the outside of the connecting rod 12. The driven gear 13 is meshed with the transmission gear 15. The connecting rods 12 are in contact with the inner wall of the bottom of the grinding barrel 2. Several layers of rolling wheels 16 are rotatably penetrated on the outside of the grinding cone 11. Several rolling wheels 16 are arranged in each layer of rolling wheels 16. Several scraping rods 17 are installed on the side of the grinding cone 11. Several unloading rings 18 are arranged in the grinding barrel 2. The number of layers of the rolling wheels 16 is the same as the number of unloading rings 18. The scraping rods 17 are in contact with the inner wall of the unloading ring 18. A protective shell 28 is sleeved on the outside of the bottom of the grinding barrel 2, and the connecting rod 12 is in contact with the inner wall of the protective shell 28.

[0026] The paint to be ground is poured into the lower hopper 1, the driving motor 6 is operated to drive the rotating shaft 7 to rotate, the rotating shaft 7 drives the transmission assembly 9 to operate, the transmission assembly 9 drives the grinding rollers 8 to move in opposite directions, and the paint is ground into powder. The powdered paint moves downward along the grinding cone 11, and the rotating grinding cone 11 continues to grind the larger paint particles. The ground paint powder moves downward, and the fine particles move downward through the lower ring 18. The larger particles contact the rolling wheel 16, and the paint particles are sandwiched between the rolling wheel 16 and the inner wall of the grinding barrel 2, squeezing the rolling wheel 16. The rotating grinding wheel 16 grinds the paint particles. At the same time, the scraper rod 17 installed on the side of the grinding cone 11 rotates to scrape off the paint powder adhering to the inner wall of the discharge ring 18. The paint leaving the discharge ring 18 moves downward under the action of its own gravity. The dual-axis motor 14 works to drive the transmission gear 15 to rotate. The transmission gear 15 pushes the driven gear 13 meshing with it to move. The driven gear 13 drives the connecting rod 12 to rotate. The connecting rod 12 scrapes off the paint adhering to the grinding cone 11 and the inner wall of the protective shell 28, thereby playing a cleaning role.

[0027] Example 2

[0028] On the basis of Example 1, Figure 5 As shown, it also includes a limit rail 23, a sliding rod 24, a knocking plate 25, a connecting frame 26 and a turntable 27. The limit rail 23 is symmetrically installed on the side of the limit ring 3. The sliding rod 24 is slidably arranged in the limit rail 23. The end of the sliding rod 24 away from the limit rail 23 is installed with a knocking plate 25. The knocking plate 25 flexibly collides with the outside of the grinding barrel 2 to shake off the paint powder of the grinding barrel 2. The upward output shaft of the inner dual-axis motor 14 is connected to the turntable 27 through a coupling. The turntable 27 is elliptical, and a connecting frame 26 is slidably arranged on the top of the turntable 27, and the connecting frame 26 is respectively connected to the knocking plate 25.

[0029] When the dual-axis motor 14 is working, it drives the turntable 27 to rotate, and the turntable 27 pushes the connecting frame 26 to move back and forth. The connecting frame 26 drives the knocking plate 25 to slide along the limiting rail 23. The knocking plate 25 collides with the outer wall of the grinding barrel 2. The grinding barrel 2 vibrates under the action of the collision force, and the paint stuck to the inner wall of the grinding barrel 2 is detached under the action of the vibration force, thereby cleaning the paint on the inner wall of the grinding barrel 2.

[0030] like Figure 3 As shown, it also includes a protective plate 19, a rotating rod 20, a torsion spring 21 and a sleeve 22. The top of the lower hopper 1 is symmetrically and rotatably provided with a protective plate 19. The protective plate 19 prevents dust and other impurities from entering the lower hopper 1. Rotating rods 20 are installed on both sides of the protective plate 19. The rotating rod 20 rotatably penetrates the side wall of the lower hopper 1. The outer side of the rotating rod 20 is covered with a torsion spring 21. One end of the torsion spring 21 is installed on the rotating rod 20, and the other end of the torsion spring 21 is installed on the side of the lower hopper 1. The outer side of the rotating rod 20 is covered with a sleeve 22.

[0031] After the paint is poured downwards, the protection plate 19 is driven to rotate under the restoring elastic force of the torsion spring 21, and the protection plate 19 is reset and then covers the top of the lower hopper 1, thereby preventing impurities from entering the lower hopper 1.
