The crushing and grinding device for paint and coating processing comprises a mixing barrel, and further comprises: a cooling mechanism; a mixing mechanism; a dispersing mechanism; and an air supply mechanism. The present invention provides a cooling mechanism so that the cooling mechanism can dissipate heat generated by grinding of a movable roller and a fixed roller, thereby preventing the pigment from heating up too high and adhering to the outer surfaces of the movable roller and the fixed roller, thereby affecting the grinding efficiency of the movable roller and the fixed roller.

Description

Technical Field

[0001] The present invention belongs to the technical field of paint and coating processing and grinding, and particularly relates to a crushing and grinding device for paint and coating processing. Background Art

[0002] The production process of paint and coating is a complex chemical process, involving multiple steps such as raw material selection, mixing, dispersion, grinding, color matching, paint adjustment, filtration, packaging, etc.; the following is the basic process of paint and coating production: Raw material preparation: Resin: Resin is the main film-forming substance of paint and coating, and commonly used ones include alkyd resin, epoxy resin, acrylic resin, etc.; Solvent: Used to dissolve the resin, and commonly used ones include toluene, xylene, acetone, etc.; Pigment: Provides the color of the coating, such as titanium dioxide, iron oxide red, etc.; Filler: Increases the thickness and strength of the coating film, such as talc powder, barium sulfate, etc.; Auxiliary agent: Improves the performance of the coating, such as leveling agent, dispersant, defoaming agent, etc.; Production process: Premixing: Preliminarily mix resin, solvent, pigment, and filler, etc. in a premixing tank; Grinding: Grind the premix through a grinding machine to refine the pigment particles and improve the uniformity and gloss of the coating; Paint adjustment: Adjust the viscosity, color, etc. of the coating according to product requirements, and some specific auxiliary agents may need to be added; Dispersion: Uniformly disperse the pigment and filler in the resin through a high-speed disperser to ensure the stability of the coating; Filtration: Filter the dispersed coating through a filter to remove undispersed particles and other impurities; Color matching: For coatings that require specific colors, perform precise color matching in a color matching machine; Packaging: After the produced coating passes the inspection, perform packaging processes such as filling, sealing, and labeling.

[0003] Currently, when grinding pigments for paint and coating, the pigments that meet the particle size after grinding need to be poured into the paint raw materials, and then the paint raw materials and pigments are mixed by stirring to form paint and coating. However, during the process of the moving roller and the stationary roller grinding the pigments, due to the extrusion and grinding of the moving roller and the stationary roller on the pigments, the moving roller and the stationary roller will heat up, and then the pigments will heat up. The heating of the pigments will cause some components in the pigments to volatilize, resulting in the produced paint and coating not meeting the standards. Moreover, it will also cause the pigments to adhere to the outer surfaces of the moving roller and the stationary roller, affecting the grinding quality and efficiency of the moving roller and the stationary roller on the pigments, and further affecting the quality of the produced paint and coating. Based on this, a crushing and grinding device for paint and coating processing is proposed. Summary of the Invention

[0018] As a further optimization solution of the present invention, the grinding assembly includes two grooves opened on the side wall of the grinding box. Two sliding plates are slidably connected in the two grooves. A first motor is fixedly connected to the side wall of one of the sliding plates. The output end of the first motor is fixedly connected to a first gear. A moving roller is rotatably connected to the adjacent side of the two sliding plates.

A plurality of magnetic strips are fixedly connected in the moving roller and the fixed roller, and the front side of the magnetic strip has the same magnetism as the front side of the magnetic sheet.

[0020] As a further optimization solution of the present invention, a feeding pipe is fixedly connected to the side wall of the mixing barrel, a discharging pipe is fixedly connected to the bottom of the mixing barrel, a feeding hopper is fixedly connected to the top of the grinding box, and the grinding box and the mixing barrel are communicated through a feeding port. The feeding port is arranged at the middle position of the top of the mixing barrel.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. Through the setting of the cooling mechanism, the present invention enables the cooling mechanism to dissipate the heat generated by the grinding of the moving roller and the fixed roller, avoiding the excessive rise in the temperature of the pigment and adhesion to the outer surfaces of the moving roller and the fixed roller, which affects the grinding efficiency of the moving roller and the fixed roller. At the same time, it reduces the wear caused by high temperature to the moving roller and the fixed roller, extends the service life of the moving roller and the fixed roller, and during the heat dissipation process, the cooling mechanism can also intermittently knock the moving roller and the fixed roller to make the moving roller and the fixed roller vibrate, so that the powdery pigment adhered to the outer surfaces of the moving roller and the fixed roller due to the temperature effect can be separated from the moving roller and the fixed roller, enabling the moving roller and the fixed roller to grind the pigment better and improving the grinding efficiency.

[0023] 2. By the combined use of a mixing mechanism, a cooling mechanism, and a dispersing mechanism, during the operation of the mixing mechanism and the cooling mechanism, the cooling mechanism will dissipate the heat generated by the grinding of the moving roller and the stationary roller, and the heated gas will be transmitted into the dispersing mechanism, driving the dispersing mechanism to perform a dispersing movement while making a circular motion along with the mixing mechanism. This enables the dispersing mechanism to not only disperse the paint raw materials and pigment powder horizontally but also vertically, facilitating the uniform dispersion of the pigment powder in the paint raw materials, making the mixing of the pigment powder and the paint raw materials more uniform, with a higher mixing effect, shortening the mixing time, improving the processing efficiency, and reducing energy consumption.

[0024] 3. By the combined use of a cooling mechanism, a gas transmission mechanism, and a dispersing mechanism, during the intermittent exhaust of the cooling mechanism, since the gas is for cooling the moving roller and the stationary roller, it has a certain temperature. The gas with temperature will be conducted into the dispersing mechanism under the action of the gas transmission mechanism and injected into the paint raw materials and pigment powder by the dispersing mechanism. When the gas with temperature is injected into the paint raw materials and pigment powder, it can increase the turbulence of the paint raw materials and pigment powder, facilitating the faster and more uniform dispersion of the raw materials in the paint raw materials. At the same time, the injection of the gas with temperature can reduce the viscosity of the mixture, making it easier for the pigment powder to disperse in the paint raw materials and improving the production efficiency. In addition, when the gas is injected into the paint raw materials, bubbles will be formed. The presence of the bubbles can prevent the sedimentation of the pigment powder and maintain the suspension state of the raw materials, which is beneficial to maintaining the uniformity of the mixture for a long time, thus further ensuring the quality of the paint coatings produced by the processing.

[0025] 4. Through the setting of the opening and closing mechanism, when the gas transmission mechanism inputs the gas with temperature into the dispersing mechanism, the opening and closing mechanism closes the gas transmission groove in the dispersing mechanism at this time, enabling the dispersing mechanism to move, expanding the dispersion range of the dispersing mechanism for the paint raw materials and pigment powder, and enabling the dispersing mechanism to perform longitudinal dispersion on the paint raw materials and pigment powder. When the dispersing mechanism reaches the maximum movement state, the opening and closing mechanism can no longer close the gas transmission groove at this time, enabling the dispersing mechanism to inject the gas with temperature into the paint raw materials and pigment powder, and at the same time enabling the dispersing mechanism to automatically reset, enabling the dispersing mechanism to disperse the paint raw materials and pigment powder and inject the gas with temperature into the paint raw materials and pigment powder, promoting the full mixing of the paint raw materials and pigment powder.

Detailed implementation manners

[0045] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following detailed implementation manners are only used to further illustrate the present application and cannot be understood as a limitation on the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0046] Example: As Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 8 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 15As shown in the figure, a crushing and grinding device for paint processing includes a mixing barrel 1 and a grinding box 4, as well as a grinding assembly installed in the grinding box 4. The grinding box 4 is fixedly connected to the top of the mixing barrel 1. The grinding assembly includes two grooves 8 opened on the side wall of the grinding box 4. Slide plates 9 are slidably connected in both of the two grooves 8. The setting of the slide plates 9 facilitates the adjustment of the position of the grinding assembly. A first motor 10 is fixedly connected to the side wall of one of the slide plates 9. The output end of the first motor 10 is fixedly connected to a first gear 11. A moving roller 13 is rotatably connected to the adjacent sides of the two slide plates 9. A first toothed ring 12 is fixedly connected to one end of the moving roller 13. The first toothed ring 12 meshes with the first gear 11. A second motor 14 is fixedly connected to the side wall of the grinding box 4. The output end of the second motor 14 is fixedly connected to a second gear 15. Both the first gear 11 and the second gear 15 are located inside the grinding box 4. A fixed roller 17 is rotatably connected inside the grinding box 4. The moving roller 13 and the fixed roller 17 rotate in opposite directions and there is a certain speed difference between them, which is convenient for grinding the pigment. A second toothed ring 16 is fixedly connected to one end of the fixed roller 17. The second toothed ring 16 meshes with the second gear 15. A pressure relief device 7 is installed on the side wall of the grinding box 4. The pressure relief end of the pressure relief device 7 is fixedly connected to the slide plate 9. The pressure relief device 7 is composed of an electric telescopic rod and a pressure relief plate. The pressure relief plate is the pressure relief end of the pressure relief device 7. The pressure relief plate is fixedly connected to the slide plate 9, which is convenient for pushing and pulling the moving roller 13 to move, so as to achieve the purpose of changing the distance between the moving roller 13 and the fixed roller 17. A feeding pipe 2 is fixedly connected to the side wall of the mixing barrel 1. The feeding pipe 2 is used to add paint raw materials into the mixing barrel 1. A discharge pipe 3 is fixedly connected to the bottom of the mixing barrel 1. A valve is installed in the discharge pipe 3. When the paint raw materials and the pigment are evenly mixed in the mixing barrel 1 to form paint coatings, the valve in the discharge pipe 3 can be opened to discharge the paint coatings. A feeding hopper 5 is fixedly connected to the top of the grinding box 4. The feeding hopper 5 is used to add the pigment to be ground into the grinding box 4. The grinding box 4 and the mixing barrel 1 are connected through a feeding port 6. The feeding port 6 is arranged at the middle position on the top of the mixing barrel 1; The mixing device further includes: a mixing mechanism 19, which is installed inside the mixing barrel 1 and is used to mix the paint raw materials and the pigment. The mixing mechanism 19 includes a mixing motor 1901 installed at the middle position of the bottom end of the mixing barrel 1. The output end of the mixing motor 1901 is fixedly connected to a rotating shaft 1902. The rotating shaft 1902 penetrates through the mixing barrel 1 and is rotatably connected to the mixing barrel 1 in a sealed manner. A material leveling plate 1903 is fixedly connected to the top of the rotating shaft 1902. Discharge holes 1904 are opened at the bottom of the material leveling plate 1903. A mixing frame 1905 is fixedly connected to the outer surface of the rotating shaft 1902.

[0047] In use, first adjust the distance between the moving roller 13 and the fixed roller 17 according to the requirements of pigment grinding. At this time, start the pressure relief device 7 so that the pressure relief device 7 extends or shortens, and then push the slide plate 9 to slide in the groove 8, causing the moving roller 13 to move. After the distance between the moving roller 13 and the fixed roller 17 meets the requirements of pigment grinding, the pressure relief device 7 can be closed. Add the paint raw materials into the mixing barrel 1 through the feeding pipe 2, and then start the first motor 10 and the second motor 14 to make the moving roller 13 and the fixed roller 17 rotate. At this time, the pigment to be ground can be added into the grinding box 4 through the feeding hopper 5. During the grinding process, start the mixing motor 1901 to make the rotating shaft 1902 rotate, thereby driving the material leveling disk 1903 and the mixing frame 1905 to rotate. The pigment powder ground by the moving roller 13 and the fixed roller 17 will fall into the material leveling disk 1903 through the feeding port 6. Due to the rotation of the material leveling disk 1903, the pigment powder will be evenly released into the paint raw materials, and in cooperation with the rotation of the mixing frame 1905, the stirring and mixing of the paint raw materials and the pigment powder are realized.

[0048] Such as Figure 2 , Figure 3 , Figure 4 , Figure 10 , Figure 11 , Figure 12 and Figure 14As shown, the crushing and grinding device further includes a cooling mechanism 18. The cooling mechanism 18 is installed inside the grinding assembly and is used to cool the grinding assembly. The cooling mechanism 18 is provided in two groups. One group is fixedly connected to the grinding box 4 through an intake solenoid tube 1801 and an exhaust solenoid tube 1808, and the other group is fixedly connected to the slide plate 9 through an intake solenoid tube 1801 and an exhaust solenoid tube 1808. And the two groups of cooling mechanisms 18 are respectively arranged inside the fixed roller 17 and the moving roller 13. The intake end of the intake solenoid tube 1801 is fixedly connected with a dust-proof net 1802, and the exhaust end of the intake solenoid tube 1801 is fixedly connected with a piston cylinder 1803. A one-way valve is installed inside the intake solenoid tube 1801, so that the piston cylinder 1803 can only draw external air through the intake solenoid tube 1801. The inner wall of the piston cylinder 1803 is hermetically slidably connected with a piston plate 1804. One side of the piston plate 1804 is fixedly connected with a piston rod 1805. The end of the piston rod 1805 is fixedly connected with a magnetic sheet 1810. A knocking spring 1806 is fixedly connected to the piston rod 1805, and the knocking spring 1806 is fixedly connected with the piston cylinder 1803. The end of the piston cylinder 1803 away from the intake solenoid tube 1801 is fixedly connected with an exhaust solenoid tube 1808. A one-way valve is installed inside the exhaust solenoid tube 1808 so that the gas in the piston cylinder 1803 can only be discharged through the exhaust solenoid tube 1808. The spiral intake solenoid tube 1801 and exhaust solenoid tube 1808 can better cool the moving roller 13 and the fixed roller 17. The exhaust end of the exhaust solenoid tube 1808 is fixedly connected with an air delivery hose 1809. A plurality of magnetic strips 1807 are fixedly connected inside both the moving roller 13 and the fixed roller 17. The magnetic strips 1807 have the same magnetic polarity as the opposite side of the magnetic sheet 1810.

[0049] During use, due to the rotation of the moving roller 13 and the fixed roller 17, the magnetic strip 1807 will intermittently align with the magnetic disk 1810. When the magnetic strip 1807 aligns with the magnetic disk 1810, the piston rod 1805 will be pushed by the magnetic repulsive force between the magnetic disk 1810 and the magnetic strip 1807 to slide the piston plate 1804 into the piston cylinder 1803, squeezing and discharging the gas that absorbs the temperature generated by the grinding of the moving roller 13 and the fixed roller 17 in the piston cylinder 1803 into the exhaust solenoid 1808. When the magnetic strip 1807 moves away from the position of the magnetic disk 1810, the piston rod 1805 will impact the inner surfaces of the moving roller 13 and the fixed roller 17 under the action of the knocking spring 1806, and the piston cylinder 1803 will draw in the air filtered by the dust-proof net 1802 through the intake solenoid 1801 into the piston cylinder 1803, enabling the outside air to absorb the temperature generated during the grinding of the moving roller 13 and the fixed roller 17. This realizes the heat dissipation operation for the heat generated by the grinding of the moving roller 13 and the fixed roller 17, avoiding the overheating of the pigment and its adhesion to the outer surfaces of the moving roller 13 and the fixed roller 17, which affects the grinding efficiency of the moving roller 13 and the fixed roller 17. At the same time, it reduces the wear caused by high temperature to the moving roller 13 and the fixed roller 17, extends the service life of the moving roller 13 and the fixed roller 17, and during the heat dissipation process, it can also intermittently knock the moving roller 13 and the fixed roller 17 to make the moving roller 13 and the fixed roller 17 vibrate, enabling the powdery pigment adhering to the outer surfaces of the moving roller 13 and the fixed roller 17 due to the temperature effect to detach from the moving roller 13 and the fixed roller 17, allowing the moving roller 13 and the fixed roller 17 to grind the pigment better and improving the grinding efficiency.

[0050] Such as Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 13 , Figure 15 , Figure 16 , Figure 17 and Figure 18As shown in the figure, the crushing and grinding device further includes: a dispersion mechanism 20, which is installed on the mixing mechanism 19 and is used to disperse the paint raw materials and pigments when mixing the paint raw materials and pigments. The dispersion mechanism 20 is provided in four groups. The dispersion mechanism 20 includes a piston chamber 2001 fixedly connected inside the mixing mechanism 19. The piston chamber 2001 is fixedly connected inside the mixing frame 1905. Two piston sheets 2002 are hermetically and slidably connected inside the piston chamber 2001. Connecting rods 2003 are fixedly connected to the opposite sides of the two piston sheets 2002. One end of the connecting rod 2003 away from the piston sheet 2002 is fixedly connected to a dispersion cross plate 2004. The dispersion cross plate 2004 is slidably connected to the inner wall of the mixing frame 1905. An inner dispersion vertical plate 2005 and an outer dispersion vertical plate 2006 are fixedly connected to the side of the dispersion cross plate 2004 close to the connecting rod 2003. The inner dispersion vertical plate 2005 and the outer dispersion vertical plate 2006 are respectively located on both sides of the piston chamber 2001. The dispersion cross plate 2004, the inner dispersion vertical plate 2005 and the outer dispersion vertical plate 2006 are used to disperse the paint raw materials and pigments. The dispersion mechanism 20 further includes a fixed block 2007 fixedly connected inside the piston chamber 2001. Elastic ropes 2008 are fixedly connected to both sides of the fixed block 2007. The elastic ropes 2008 penetrate through the connecting rod 2003 and are fixedly connected to the middle position inside the connecting rod 2003. An air delivery groove 2009 is opened inside the connecting rod 2003. An opening and closing mechanism 22 is installed inside the piston chamber 2001. The opening and closing mechanism 22 corresponds to the position of the air delivery groove 2009, and the opening and closing mechanism 22 is used to open or close the air delivery groove 2009. A one-way valve is installed in the air delivery groove 2009 so that the gas inside the piston chamber 2001 can only be discharged through the air delivery groove 2009. The air delivery groove 2009 is communicated with the inside of the piston chamber 2001. A communication groove 2010 is opened inside the dispersion cross plate 2004. The communication groove 2010 is communicated with the inside of the air delivery groove 2009. An exhaust groove 2011 is opened inside the outer dispersion vertical plate 2006. The exhaust groove 2011 is communicated with the inside of the communication groove 2010. Exhaust holes 2012 are opened on the side wall of the outer dispersion vertical plate 2006. The exhaust holes 2012 are communicated with the inside of the exhaust groove 2011. One-way valves are installed in the exhaust holes 2012 so that the gas with temperature can only flow into the paint raw materials and pigment powders through the exhaust holes 2012. A scraping rod 2013 is fixedly connected to the end of the dispersion cross plate 2004. The scraping rod 2013 is attached to the inner wall of the mixing barrel 1;The crushing and grinding device also includes: an air delivery mechanism 21, which is fixedly connected to the mixing barrel 1, and the air delivery mechanism 21 is used to transfer the gas in the cooling mechanism 18 into the dispersion mechanism 20, so as to provide power for the dispersion mechanism 20 to disperse the paint raw materials and pigments. The air delivery mechanism 21 includes a connecting pipe 2101 fixedly connected to the side wall of the mixing barrel 1, and the air delivery hose 1809 is fixedly connected to the connecting pipe 2101. The connecting pipe 2101 passes through the side wall of the mixing barrel 1 and extends to the interior of the mixing barrel 1. One end of the connecting pipe 2101 located inside the mixing barrel 1 is fixedly connected to a fixed sleeve 2102, and the fixed sleeve 2102 is sealed and rotatably connected to the outer surface of the rotating shaft 1902. The air delivery mechanism 21 also includes a conveying groove 2103 opened in the rotating shaft 1902, and the side wall of the rotating shaft 1902 is provided with an air inlet 2104. The air inlet 2104 communicates with the interior of the delivery trough 2103. The air inlet 2104 is located within the fixed sleeve 2102 and communicates with the interior of the fixed sleeve 2102. A delivery pipe 2105 is fixedly connected to the sidewall of the rotating shaft 1902. The delivery pipe 2105 communicates with the interior of the delivery trough 2103 and is fixedly connected to the middle of the piston chamber 2001. The delivery pipe 2105 communicates with the interior of the piston chamber 2001. A one-way valve is installed in the delivery pipe 2105, ensuring that gas can only flow from the delivery pipe 2105 to the piston chamber 2001. It should be noted that the combined internal volumes of the piston cylinders 1803 within the two cooling mechanisms 18 are greater than the combined internal volumes of the piston chambers 2001 within the four dispersion mechanisms 20. This allows the piston cylinders 1803 to slide the piston plate 2002 to the end of the piston chamber 2001 during exhaust.

[0051] During use, during the circular motion of the mixing rack 1905, it will drive the dispersion cross plate 2004, the inner dispersion vertical plate 2005, and the outer dispersion vertical plate 2006 to perform circular motion, causing the dispersion cross plate 2004, the inner dispersion vertical plate 2005, and the outer dispersion vertical plate 2006 to stir and mix the paint raw materials and pigment powder. During this process, the temperature-bearing gas discharged through the exhaust solenoid tube 1808 will be discharged into the connecting pipe 2101 through the gas transmission hose 1809, then enter the fixed sleeve 2102, and then enter the conveying groove 2103 through the air inlet hole 2104, and finally enter the piston chamber 2001 through the conveying pipe 2105. When the piston cylinder 1803 exhausts air, at this time, since the opening and closing mechanism 22 closes the air transmission groove 2009, the piston piece 2002 will slide towards the end in the piston chamber 2001 under the action of air pressure, stretching the elastic cord 2008, and then drive the inner dispersion vertical plate 2005 and the outer dispersion vertical plate 2006 to move towards the upper and lower sides through the dispersion cross plate 2004 until the piston cylinder 1803 stops exhausting air. And due to the reciprocating air extraction and exhaust of the piston cylinder 1803, the air pressure in the piston chamber 2001 will gradually increase. When the air pressure in the piston chamber 2001 gradually increases to when the piston piece 2002 reaches the specified position, at this time, the opening and closing mechanism 22 opens the air transmission groove 2009, and the piston piece 2002 will slide inwards under the action of the elastic cord 2008. At this time, the temperature-bearing gas inside the piston chamber 2001 will enter the communication groove 2010 through the air transmission groove 2009, then enter the exhaust groove 2011, and finally be injected into the paint raw materials and pigment powder through the exhaust hole 2012, enabling the dispersion cross plate 2004, the inner dispersion vertical plate 2005, and the outer dispersion vertical plate 2006 to not only perform horizontal dispersion on the paint raw materials and pigment powder but also perform vertical dispersion, which helps the pigment powder to be evenly dispersed in the paint raw materials, making the mixing of the pigment powder and the paint raw materials more uniform, with a higher mixing effect, shortening the mixing time, improving the processing efficiency, reducing energy consumption, and when the temperature-bearing gas is injected into the paint raw materials and pigment powder, it can increase the turbulence of the paint raw materials and pigment powder, contributing to faster and more uniform mixing between the raw materials. At the same time, the injection of the temperature-bearing gas can reduce the viscosity of the mixture, making it easier for the pigment powder to be dispersed in the paint raw materials, improving the production efficiency. In addition, when the gas is injected into the paint raw materials, bubbles will be formed. The existence of the bubbles can prevent the pigment powder from settling, maintaining the suspension state of the raw materials, which is beneficial to maintaining the uniformity of the mixture for a long time, thus further ensuring the quality of the paint coating produced by the processing;

[0052] In addition, during the circular motion and dispersion motion of the dispersion cross plate 2004, the inner dispersion vertical plate 2005, and the outer dispersion vertical plate 2006, the scraping rod 2013 will also perform circular motion and dispersion motion. Since the scraping rod 2013 is attached to the inner surface of the mixing barrel 1, it can scrape the paint raw materials on the inner wall of the mixing barrel 1 away from the inner wall of the mixing barrel 1, enabling the paint raw materials near the inner wall of the mixing barrel 1 to be fully mixed with the pigment powder, further improving the uniformity and efficiency of the mixing of the paint raw materials and the pigment powder.

[0053] As Figure 7 , Figure 9 , Figure 16 and Figure 18 shown, the crushing and grinding device further includes: an opening and closing mechanism 22, which is installed in the dispersion mechanism 20 and is used to change the motion state of the dispersion mechanism 20. The opening and closing mechanism 22 includes a sealing chute 2204 penetratingly opened on the side wall of the piston piece 2002. Two matching sealing blocks 2201 are hermetically slidably connected in the sealing chute 2204. One end of each of the two sealing blocks 2201 is fixedly connected with a magnetic block 2202. The sealing chute 2204 penetrates the air delivery groove 2009 and communicates with the inside of the air delivery groove 2009. The opening and closing mechanism 22 further includes a first magnetic plate 2203 and a second magnetic plate 2205 fixedly connected to the inner wall of the piston chamber 2001. The first magnetic plate 2203 is fixedly connected to the middle position of the piston chamber 2001, and the second magnetic plate 2205 is fixedly connected to the upper and lower sides of the piston chamber 2001. The opposite surface of the second magnetic plate 2205 and the magnetic block 2202 has opposite magnetism.

[0054] In use, at the initial stage, the magnetic block 2202 faces the first magnetic plate 2203, so that the two sealing blocks 2201 seal the air delivery groove 2009. When high-temperature gas enters the piston chamber 2001 through the delivery pipe 2105, due to the sealing of the air delivery groove 2009, the piston piece 2002 will slide towards the end of the piston chamber 2001. When the piston piece 2002 slides to the position of the piston chamber 2001 where there is a second magnetic plate 2205, the second magnetic plate 2205 will face the magnetic block 2202, causing the second magnetic plate 2205 to attract the magnetic block 2202 to slide outwards, so that the two sealing blocks 2201 cannot seal the air delivery groove 2009, and the exhaust hole 2012 starts to discharge the gas with temperature. During the process of discharging the gas inside the piston chamber 2001, the piston piece 2002 slides inwards until the gas inside the piston chamber 2001 is completely discharged. When the gas is completely discharged, at this time, the magnetic block 2202 will reach the position where the first magnetic plate 2203 is located, causing the sealing block 2201 to re-seal the air delivery groove 2009 under the repulsive force of the first magnetic plate 2203 and the magnetic block 2202, enabling the dispersion mechanism 20 to disperse the paint raw materials and pigment powder, and at the same time enabling the dispersion mechanism 20 to inject the gas with temperature into the paint raw materials and pigment powder, promoting the full mixing of the paint raw materials and pigment powder.

[0055] The specific working principle of the present invention is as follows: In use, first adjust the distance between the moving roller 13 and the fixed roller 17 according to the pigment grinding requirements. At this time, start the pressure relief device 7 to make the pressure relief device 7 extend or shorten, and then push the sliding plate 9 to slide in the groove 8, so that the moving roller 13 moves. After the distance between the moving roller 13 and the fixed roller 17 meets the pigment grinding requirements, the pressure relief device 7 can be closed. Add the paint raw materials into the mixing barrel 1 through the feeding pipe 2, and then start the first motor 10 and the second motor 14 to make the moving roller 13 and the fixed roller 17 rotate. At this time, the pigment to be ground can be added into the grinding box 4 through the feeding hopper 5. And during the grinding process, start the mixing motor 1901 to make the rotating shaft 1902 rotate, thereby driving the material leveling plate 1903 and the mixing frame 1905 to rotate. The pigment powder ground by the moving roller 13 and the fixed roller 17 will fall into the material leveling plate 1903 through the feeding port 6. Due to the rotation of the material leveling plate 1903, the pigment powder will be evenly released into the paint raw materials, and in cooperation with the rotation of the mixing frame 1905, the stirring and mixing of the paint raw materials and pigment powder are realized.

[0056] Meanwhile, due to the rotation of the moving roller 13 and the fixed roller 17, the magnetic strip 1807 will intermittently align with the magnetic disc 1810. When the magnetic strip 1807 aligns with the magnetic disc 1810, the piston rod 1805 will push the piston plate 1804 to slide into the piston cylinder 1803 under the action of the magnetic repulsive force between the magnetic disc 1810 and the magnetic strip 1807, squeezing and discharging the gas that absorbs the temperature generated by the grinding of the moving roller 13 and the fixed roller 17 in the piston cylinder 1803 into the exhaust solenoid 1808. When the magnetic strip 1807 moves away from the position of the magnetic disc 1810, the piston rod 1805 will impact the inner surfaces of the moving roller 13 and the fixed roller 17 under the action of the knocking spring 1806, and the piston cylinder 1803 will draw in the air filtered by the dust-proof net 1802 through the intake solenoid 1801 into the piston cylinder 1803, enabling the outside air to absorb the temperature generated during the grinding of the moving roller 13 and the fixed roller 17. This realizes the heat dissipation operation for the heat generated by the grinding of the moving roller 13 and the fixed roller 17, avoiding the overheating of the pigment and its adhesion to the outer surfaces of the moving roller 13 and the fixed roller 17, which affects the grinding efficiency of the moving roller 13 and the fixed roller 17. At the same time, it reduces the wear caused by high temperature to the moving roller 13 and the fixed roller 17, extends the service life of the moving roller 13 and the fixed roller 17, and during the heat dissipation process, it can also intermittently knock the moving roller 13 and the fixed roller 17 to make them vibrate, enabling the powdery pigment adhered to the outer surfaces of the moving roller 13 and the fixed roller 17 due to the temperature effect to break away from the moving roller 13 and the fixed roller 17, enabling the moving roller 13 and the fixed roller 17 to grind the pigment better and improving the grinding efficiency;

[0057] And during this process, while the mixing frame 1905 is moving in a circular motion, it will drive the dispersion cross plate 2004, the inner dispersion vertical plate 2005, and the outer dispersion vertical plate 2006 to move in a circular motion, causing the dispersion cross plate 2004, the inner dispersion vertical plate 2005, and the outer dispersion vertical plate 2006 to stir and mix the paint raw materials and pigment powder. At this time, since the magnetic block 2202 is facing the first magnetic plate 2203, the two sealing blocks 2201 seal the air delivery groove 2009. The temperature-bearing gas discharged through the exhaust solenoid pipe 1808 will be discharged into the connecting pipe 2101 through the air delivery hose 1809, then enter the fixed sleeve 2102, then pass through the air inlet hole 2104 into the delivery groove 2103, and finally enter the piston chamber 2001 through the delivery pipe 2105. During the process of the piston cylinder 1803 sucking and exhausting air, and when the air delivery groove 2009 is sealed, at this time the piston piece 2002 will slide towards the end in the piston chamber 2001, stretching the elastic cord 2008, and then drive the inner dispersion vertical plate 2005 and the outer dispersion vertical plate 2006 to move towards the upper and lower sides through the dispersion cross plate 2004 until the piston cylinder 1803 stops exhausting air. And due to the reciprocating sucking and exhausting of the piston cylinder 1803, the air pressure in the piston chamber 2001 will gradually increase. As the air pressure in the piston chamber 2001 gradually increases to when the piston piece 2002 reaches the position where the second magnetic plate 2205 is located, at this time, since the piston piece 2002 is located at the position of the piston chamber 2001 where the second magnetic plate 2205 is located, the second magnetic plate 2205 will face the magnetic block 2202, causing the second magnetic plate 2205 to attract the magnetic block 2202 to slide outwards, making the two sealing blocks 2201 unable to seal the air delivery groove 2009;

[0058] At this time, due to the opening of the air delivery groove 2009, the piston piece 2002 will slide inward under the action of the elastic cord 2008. At this time, the gas with temperature inside the piston chamber 2001 will enter the communication groove 2010 through the air delivery groove 2009, then enter the exhaust groove 2011, and finally be injected into the paint raw materials and pigment powder through the exhaust hole 2012 until the magnet 2202 reaches the position where the first magnetic plate 2203 is located. When the magnet 2202 reaches the position where the first magnetic plate 2203 is located, the sealing block 2201 will reseal the air delivery groove 2009 under the repulsive force of the first magnetic plate 2203 and the magnet 2202, so as to facilitate the next dispersion action of the dispersion cross plate 2004, the inner dispersion vertical plate 2005 and the outer dispersion vertical plate 2006, enabling the dispersion cross plate 2004, the inner dispersion vertical plate 2005 and the outer dispersion vertical plate 2006 to not only disperse the paint raw materials and pigment powder horizontally but also vertically, which helps the pigment powder to be evenly dispersed in the paint raw materials, making the mixing of the pigment powder and the paint raw materials more uniform, with a higher mixing effect, shortening the mixing time, improving the processing efficiency, reducing the energy consumption, and the gas with temperature can increase the turbulence of the paint raw materials and pigment powder when injected into them, which helps the raw materials to be mixed more quickly and evenly. At the same time, the injection of the gas with temperature can reduce the viscosity of the mixture, making it easier for the pigment powder to be dispersed in the paint raw materials and improving the production efficiency. In addition, when the gas is injected into the paint raw materials, bubbles will be formed. The existence of the bubbles can prevent the pigment powder from settling, maintaining the suspended state of the raw materials, which is beneficial to maintaining the uniformity of the mixture for a long time, thus further ensuring the quality of the paint coating produced by the processing;

[0059] In addition, during the circular motion and dispersion motion of the dispersion cross plate 2004, the inner dispersion vertical plate 2005 and the outer dispersion vertical plate 2006, the scraping rod 2013 will also perform circular motion and dispersion motion. And because the scraping rod 2013 is attached to the inner surface of the mixing barrel 1, it can scrape the paint raw materials on the inner wall of the mixing barrel 1 away from the inner wall of the mixing barrel 1, enabling the paint raw materials near the inner wall of the mixing barrel 1 to be fully mixed with the pigment powder, further improving the uniformity and efficiency of the mixing of the paint raw materials and the pigment powder;

[0060] After the stirring and mixing reach the specified time to obtain the paint coating, the first motor 10, the second motor 14 and the mixing motor 1901 can be turned off, and the valve in the discharge pipe 3 can be opened to discharge the paint coating obtained from the processing production.

[0061] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
