Description

[0002] In the paint and coating production process, the grinding of raw materials is the core link that affects the quality of the finished product. Traditional grinding equipment usually uses a single crushing and rolling process, which has problems such as low crushing efficiency, poor particle uniformity, and incomplete sorting.

[0003] Existing crushing structures mostly use a one-way crushing method, which leads to insufficient material crushing and the easy retention of large particles. The crushing link lacks a pressure regulation function and is difficult to adapt to the characteristics of different materials, which can easily cause excessive crushing or insufficient crushing. In addition, the sorting system mostly relies on simple screens, and the separation efficiency of fine powder and substandard particles is low, requiring repeated processing, which increases energy consumption and time costs. Although some equipment has tried to introduce automated structures, the coordination between the components is poor, the material flow is not smooth, and there is a lack of the ability to dynamically adjust the grinding process, resulting in limited equipment adaptability. In view of this, there may be technical means to solve the above problems in the existing technology, but this case intends to provide an alternative or replacement technical solution.

[0040] When grinding paint, the staff first moves the device to the designated position, supports the device through the bottom plate 1, and connects it to the control system. Then, the raw materials are poured into the material storage box 2. Under the action of the inclined surface of the inclined guide frame 3 in the material storage box 2, the raw materials are located at the lower end of the material elevator 4. Then, the material elevator 4 works and transports the raw materials through the feed pipe 7 to the operating box 8. Then, the crushing motor 10 on one side of the crushing box 6 is driven to work, driving the first bevel gear 11 to rotate at high speed. When the two second bevel gears 14 are at the same level as the first bevel gear, the crushing motor 10 on the other side of the crushing box 6 is driven to work and drive the first bevel gear 11 to rotate at high speed. Under the meshing action of the wheel 11, the two transmission shafts 13 are driven to rotate at high speed in the two bearing seats 12. At the same time, under the connection action of the two chains 18 and the two first sprockets 15 and the two second sprockets 17, the two operating shafts 16 are made to rotate at high speed in opposite directions on both sides of the operating box 8, driving several breaking hammers 20 to rotate in the operating box 8, crushing the raw materials in the operating box 8, and screening the raw materials through the set first screen 9 to ensure the crushing effect of the raw materials. Subsequently, by adjusting the working of the crushing structure, the preliminarily crushed raw materials are further crushed and pulverized.

[0041] In the specific implementation process, the regulating and rolling structure includes: a first collection pipe 21, a rolling box 22, a second collection pipe 23, a fixing frame 24, two electric push rods 25, a rolling platform 26, a rolling motor 27, a drive shaft 28, a mounting shell 29, a protective tube 30, two rolling rollers 31, a cleaning and toggling assembly, and a filtering assembly;

[0042] The top of the first collecting pipe 21 is connected to the center of the lower end of the crushing box 6, the rolling box 22 is fixedly installed at the center of the support frame 5, and the top is connected to the bottom end of the first collecting pipe 21, the top of the second collecting pipe 23 is connected to the lower end of the rolling box 22, the fixed frame 24 is fixedly installed in the rolling box 22, the two electric push rods 25 are respectively installed on both sides of the lower end of the fixed frame 24, the rolling platform 26 is fixedly installed on the upper end of the fixed frame 24, the rolling motor 27 is fixedly installed on one side of the telescopic end of the two electric push rods 25, and the drive shaft 28 is fixedly installed in the rolling box 22. One end is connected to the driving end of the rolling motor 27, and the other end is movable through the fixed frame 24 and the center of the rolling platform 26. The mounting shell 29 is fixedly installed on the top of the driving shaft 28, and the protective tube 30 is fixedly installed at the center of the upper end of the rolling platform 26. The bottom end of the mounting shell 29 is movably fitted to the outside of the protective tube 30. One end of the two rolling rollers 31 is respectively connected to the left and right side walls of the mounting shell 29. One end of the cleaning and toggling component is movably embedded in the front and rear side walls of the mounting shell 29. The filter component is fixedly installed on the upper end of the rolling platform 26.

[0043] When the raw materials that have undergone preliminary crushing pass through the first screen 9 and fall into the first collecting pipe 21, they are transported to the rolling box 22 through the first collecting pipe 21 and fall into the filtering component and the upper end of the rolling platform 26. The rolling platform 26 is fixed by the fixing frame 24, and then the two electric push rods 25 at the lower end of the fixing frame 24 are driven to change the installation height of the rolling motor 27 and the drive shaft 28 until the two rolling rollers 31 on both sides of the installation shell 29 maintain a specified distance from the rolling platform 26. Then, the rolling motor 27 is driven to work, driving the drive shaft 28 and the installation shell 29 to rotate slowly, so that the rolling roller 31 rotates on the upper end of the rolling platform 26, and further rolling the raw materials. , and with the continuous rolling, the two electric push rods 25 located at the lower end of the fixed frame 24 continue to extend until the rolling operation of the raw materials is completed, and the cleaning and toggling components are arranged to rotate with the installation shell 29 to toggle and clean the paint adhering to the surface of the rolling platform 26. Finally, the paint that meets the rolling requirements is filtered and discharged through the filtering component, and then transported to the sorting box 37 through the second collection pipe 23 for final sorting and transportation. In addition, the protective pipe 30 is arranged to fill the gap between the installation shell 29 and the rolling platform 26 when the installation shell 29 rises, so as to prevent the paint from entering the installation shell 29 and affecting the parts, thereby ensuring the processing stability of the paint.

[0044] In the specific implementation process, the cleaning and toggling assembly includes: a fixed rubber ring 32, two cleaning rollers 33 and two rubber wheels 34;

[0046] When cleaning the paint adhered to the upper end of the rolling platform 26, as the mounting shell 29 follows the motor to descend, the two rubber wheels 34 at one end of the two cleaning rollers 33 can contact the fixed rubber ring 32 at the upper end of the rolling platform 26. Under the friction between the fixed rubber ring 32 and the rubber wheels 34, the two rubber wheels 34 roll on the upper end of the fixed rubber ring 32 and drive the two cleaning rollers 33 to rotate, stirring and cleaning the paint on the upper end of the rolling platform 26, thereby ensuring the rolling efficiency and processing effect of the paint.

[0047] In the specific implementation process, the filter assembly includes: an annular filter frame 35 and four filter plates 36;

[0048] The annular filter frame 35 is fixedly mounted on the upper end of the rolling platform 26 , and the four filter plates 36 are respectively embedded in the side walls of the annular filter frame 35 .

[0049] When the paint is crushed, the annular filter frame 35 cooperates with the four filter plates 36 to block the initially crushed raw materials to ensure the contact effect with the crushing roller 31. Then, the four filter plates 36 are set to further filter the raw materials and block large particles of raw materials.

[0050] In the specific implementation process, the sorting and conveying structure includes: a sorting box 37, a second screen 38, a conveying sleeve 39 and a screw conveyor 40;

[0051] The sorting box 37 is fixedly installed at the lower end of the support frame 5, the second screen 38 is obliquely installed in the sorting box 37, the conveying sleeve 39 is fixedly installed at the lower end of the sorting box 37 and is connected to the lower wall of the sorting box 37, and the screw conveyor 40 is installed in the conveying sleeve 39.

[0052] The crushed and ground paint is transported to the sorting box 37 through the second collecting pipe 23 and falls on the upper end of the inclined second screen 38. The paint is then further screened by the second screen 38. The paint that meets the crushing requirements falls through the second screen 38 and falls into the conveying sleeve 39. The paint that meets the requirements is conveyed by the screw conveyor 40, while the paint that does not meet the requirements is conveyed to the material storage box 2 through the inclined second screen 38 for crushing and crushing again.

[0053] In a specific implementation process, the surfaces of the rolling roller 31 and the rolling platform 26 are both frosted surfaces.

[0054] During the specific implementation process, two connecting frames 41 are installed between the material hoist 4 and the support frame 5.

[0055] A method for using a paint and coating grinding and processing device comprises the following steps:

[0056] Step S1: In the system preparation phase, the grinding device is transported to the designated workstation using a mobile chassis, the device is fixed using a base plate, the control system power is turned on, and the device self-test is completed;

[0057] Step S2: Raw material crushing process: the paint raw material to be processed is injected into the material storage bin, and the raw material is guided into the feed port of the vertical material elevator through the inclined material guide frame.
