Description

Technical Field

[0001] This application relates to the field of coating production technology, and in particular to a grinding mill for coating production and a grinding method thereof. Background Technology

[0002] In the paint manufacturing process, raw materials are generally first poured into a grinding tool, and then the grinding device is used to grind the raw materials so that they can be fully mixed to obtain paint that meets the standards; therefore, the grinding process is one of the key steps in paint manufacturing.

[0003] In related technologies, the raw materials are usually mixed manually to obtain a quantitative ratio. Then, the mixed raw materials are fed into a grinding machine and ground by the grinding disc in the grinding machine to obtain the final ground coating.

[0004] Regarding the aforementioned technologies, traditional paint grinding machines require manual mixing of raw materials, which is very labor-intensive and has a low overall level of automation, severely reducing the grinding efficiency of paints. Therefore, improvements are needed. Summary of the Invention

[0005] To improve the grinding efficiency of coatings, this application provides a grinding mill for coating production and a grinding method thereof.

[0006] Firstly, this application provides a grinding mill for paint production, which adopts the following technical solution: A grinding mill for paint production includes a machine body and a grinding chamber located inside the machine body. A material collection box, connected to the bottom of the grinding chamber, is slidably engaged at the bottom of the machine body. A feed inlet, communicating with the interior of the grinding chamber, is penetrating through the top of the machine body. A feed pipe is connected to the feed inlet. Several storage bins for storing different raw materials are located on the top of the machine body. A batching assembly is located between the feed pipe and the storage bins for automatically batching raw materials. A pushing assembly is located on the feed pipe to push the material inside the feed pipe into the grinding chamber. A grinding assembly is located on the machine body to grind the material inside the grinding chamber.

[0007] By adopting the above technical solution, the batching component automatically proportions the raw materials in different storage bins inside the feed pipe, the pushing component pushes the proportioned material inside the feed pipe into the grinding chamber, the grinding component fully grinds the material inside the grinding chamber, and finally the ground coating product is collected through the collection box, thus realizing the automated and efficient proportioning and grinding of coatings, thereby improving the grinding efficiency of coatings.

[0008] Preferably, the batching assembly includes a feeding pipe, an electrically controlled valve, a frame, a sliding plate, a carrying plate, a moving cylinder, a weighing component, and a control component. The feeding pipe is connected between each set of storage bins and the feeding pipe. The electrically controlled valve is installed on each set of feeding pipes to control the communication state inside the corresponding feeding pipe. The frame is located on the top of the machine body, and the feeding pipe is installed on the frame. The sliding plate is slidably disposed between the feeding pipe and the machine body. The carrying plate is embedded in the top wall of the sliding plate, and the side wall of the carrying plate away from the sliding plate is in contact with the feeding pipe to carry the raw materials inside the feeding pipe. The moving cylinder is located on the top of the machine body to drive the sliding plate to slide the carrying plate relative to the feeding pipe. The sliding plate has a through-hole that connects to the feeding pipe and the feed inlet. The weighing component is disposed between the sliding plate and the loading plate, and the control component is disposed on the top of the machine body. Both the electric control valve and the weighing component are electrically connected to the control component. The weighing component is used to weigh the raw material on the loading plate and issue initial weight data. After any of the electric control valves is opened, the weighing component weighs the material and issues additional weight data. The control component is used to receive the initial weight data and the additional weight data. When the difference between the additional weight data and the initial weight data is equal to the preset value corresponding to the electric control valve inside the control component, the control component controls the electric control valve to close the corresponding feed pipe.

[0009] By adopting the above technical solution, the electric control valve, weighing device and control valve measure and control the weight of the material fed into the feed pipe in each set of feed pipes in a timely manner, so as to achieve precise feeding of a variety of different materials into the feed pipe and achieve efficient proportioning; after proportioning, the control of the moving cylinder drives the sliding plate to slide the material plate, so that the connecting port is connected to the feed pipe and the feed inlet, thereby facilitating the rapid introduction of the proportioned material into the grinding chamber.

[0010] Preferably, the pushing assembly includes a fixed frame, a pushing plate, and a pushing cylinder; the fixed frame is mounted on the machine frame, the pushing plate is slidably mounted inside the feed pipe, and the peripheral wall of the pushing plate is in contact with the inner peripheral wall of the feed pipe; the pushing cylinder is mounted on the fixed frame to drive the pushing plate closer to or away from the machine body.

[0011] By adopting the above technical solution, the pusher cylinder drives the pusher plate to move along the length of the feed pipe, so as to push the material adhering to the inner wall of the feed pipe into the grinding chamber, thereby reducing the waste and loss of material inside the feed pipe, saving costs, and ensuring the accuracy of material ratio.

[0012] Preferably, the feeding assembly further includes a sliding roller, a rotating shaft, a rotating motor, a positioning rod, a scraping rope, and a shock-absorbing component; the sliding roller is slidably disposed at the end of the feed pipe away from the machine body, and the end of the sliding roller away from the machine body is connected to the output end of the feeding cylinder; the rotating shaft is rotatably disposed at the end of the sliding roller facing the feeding plate, and the end of the rotating shaft away from the sliding roller is connected to the feeding plate; the rotating motor is disposed on the sliding roller to drive the rotating shaft to rotate; the positioning rod is disposed inside the machine body, the scraping rope is disposed on the positioning rod, and the scraping rope can abut against the side wall of the feeding plate away from the rotating shaft to scrape off the material adhering to the feeding plate; the shock-absorbing component is disposed on the rotating shaft to shock the scraping rope.

[0013] By adopting the above technical solution, after the pusher plate enters the grinding chamber and abuts against the scraper rope, the rotating motor drives the rotating shaft to rotate the pusher plate relative to the scraper rope. The scraper rope cleans the material adhering to the pusher plate and puts it into the grinding chamber. The shock-absorbing component shocks the scraper rope, reducing the material adhering to the scraper rope, reducing the waste and loss of material after proportioning, saving costs, and ensuring the accuracy of material proportioning.

[0014] Preferably, the shock-absorbing component includes a fixed rod, a sliding cylinder, an anti-detachment plate, a reset component, and a shock-absorbing plate; the fixed rod is disposed on the rotating shaft, the sliding cylinder is slidably sleeved on the fixed rod, the anti-detachment plate is disposed at the end of the fixed rod away from the rotating shaft to prevent the sliding cylinder from detaching from the fixed rod; the reset component is disposed between the anti-detachment plate and the sliding cylinder to drive the sliding cylinder closer to the rotating shaft for reset by its own elastic force; the shock-absorbing plate is disposed at the end of the sliding cylinder away from the rotating shaft to shock the positioning rod.

[0015] By adopting the above technical solution, in the initial state, both the sliding cylinder and the vibration plate are located between the inner circumferential wall of the pusher plate and the feed pipe, reducing the interference between the vibration plate and the feed pipe. When the rotating shaft drives the pusher plate to rotate, the scraper rope scrapes off the material adhering to the pusher plate. The sliding cylinder, under the action of centrifugal force, gradually drives the vibration plate away from the rotating shaft, causing the vibration plate to vibrate the positioning rod, and causing the positioning rod and the scraper rope to vibrate, reducing the material adhering to their surfaces. When the rotating shaft drives the pusher plate to stop, the reset component gradually restores its deformation using its own elasticity, causing the sliding cylinder to drive the vibration plate to gradually approach the rotating shaft to achieve reset.

[0016] Preferably, the grinding assembly includes a grinding roller, a grinding disc, a grinding motor, and grinding balls; the grinding roller is rotatably mounted on the machine body, the grinding disc is sleeved on the grinding roller, and the grinding discs are spaced apart along the length of the grinding roller; the inner diameter of the grinding chamber gradually increases towards the material collection box, and the distance between the peripheral wall of each grinding disc and the inner peripheral wall of the grinding chamber gradually decreases towards the material collection box; the grinding motor is located at the top of the machine body to drive the grinding roller to rotate; the grinding balls are located on the outer peripheral wall of each set of grinding discs for grinding materials.

[0017] By adopting the above technical solution, the grinding motor drives the grinding roller to rotate the grinding disc and grinding balls, so as to grind the material inside the grinding chamber. In addition, the spaced grinding discs facilitate the classification of the material inside the machine body, reducing the phenomenon of material accumulating in one place and affecting grinding efficiency.

[0018] Preferably, the top of the machine body is provided with a lifting frame, the grinding motor is located on the lifting frame, and the end of the grinding roller away from the collection box is connected to the lifting frame; the top of the machine frame is provided with a reference frame, and the reference frame is provided with a lifting component for driving the lifting frame and the grinding roller to move up and down synchronously; the bottom of the machine body is provided with a rotating component for driving the machine body to rotate.

[0019] By adopting the above technical solution, after the material is ground, the lifting component drives the lifting frame to lower the grinding roller, which in turn drives the grinding disc to descend inside the grinding chamber. This increases the gap between the inner wall of the grinding chamber and each set of grinding discs. The rotating component drives the machine body to rotate. Under the action of centrifugal force, the material adhering to the grinding disc and the inner wall of the grinding chamber gradually flows towards the inside of the collection box, which facilitates the rapid removal of the ground material inside the grinding chamber and reduces the waste caused by the material remaining inside the grinding chamber.

[0020] Preferably, the rotating assembly includes a base, a rotating shaft, and a rotating motor; the base is disposed at the bottom of the machine body, the rotating shaft is rotatably disposed on the side wall of the base facing the machine body, and the rotating shaft is connected to the machine body; the rotating motor is disposed inside the base to drive the rotating shaft and the machine body to rotate.

[0021] By adopting the above technical solution, the rotary motor drives the rotary shaft to rotate the machine body, thereby realizing the machine body's rotation.

[0022] Preferably, a pressure pump is provided on the top of the machine body, and the output end of the pressure pump is provided with a pressure pipe that communicates with the inside of the grinding chamber.

[0023] By adopting the above technical solution, the pressure pump increases the air pressure inside the machine body through the pressure pipe. The material inside the grinding chamber is under pressure, which causes the material inside the machine body to move quickly toward the collection box so that it can be squeezed between the grinding disc and the inner wall of the grinding chamber for grinding, thereby improving the grinding efficiency of the material inside the grinding chamber.

[0024] Secondly, This application provides a grinding method for a grinding mill used in paint production, comprising the following steps: Ingredient mixing: The ingredient mixing unit automatically mixes the raw materials from different storage bins into the feed pipe; Pushing: The pushing component pushes the proportioned material inside the feed pipe into the grinding chamber; Grinding: The grinding components thoroughly grind the material inside the grinding chamber; Discharge: The ground material falls into the collection box for collection. The collection box is then removed to take out the ground coating.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a batching component, the raw materials in different storage bins are automatically proportioned in the feed pipe. The pushing component pushes the proportioned material in the feed pipe into the grinding chamber. The grinding component grinds the material in the grinding chamber thoroughly. Finally, the ground paint product is collected through the collection box. This achieves automated and efficient proportioning and grinding of paint, thereby improving the grinding efficiency of paint. 2. By setting a pusher plate to enter the grinding chamber and abut against the scraper rope, the rotating motor drives the rotating shaft to rotate the pusher plate relative to the scraper rope. The scraper rope cleans the material adhering to the pusher plate and puts it into the grinding chamber. The vibration component vibrates the scraper rope, reducing the material adhering to the scraper rope, reducing the waste and loss of material after proportioning, saving costs, and ensuring the accuracy of material proportioning. 3. By setting up a pressure pump to increase the air pressure inside the machine body through the pressure pipe, the material inside the grinding chamber is subjected to pressure, which causes the material inside the machine body to move quickly toward the collection box, so as to squeeze into the grinding disc and the inner wall of the grinding chamber for grinding, thereby improving the grinding efficiency of the material.

After any solenoid valve 22 is opened, the weighing element 27 continuously weighs the material carrier plate 25 and sends the weight data to the control element 28 as the additional material weight data. The control element 28 receives the initial weight data and the additional material weight data, and compares the difference between the additional material weight data and the initial weight data with the preset value corresponding to each group of solenoid valves 22. When the two are consistent, the control element 28 controls the solenoid valve 22 to close the corresponding feed pipe 21, thereby achieving precise feeding into the feed pipe 14.

[0050] The implementation principle of a grinding mill for paint production according to an embodiment of this application is as follows: Opening the solenoid valve 22 connects the feed pipe 21 to the feed pipe 14. After the material inside the storage bin 15 flows into the feed pipe 14, the loading plate 25 and the weighing device 27 weigh the material flowing into the feed pipe 14. When the difference between the added weight data and the initial weight data measured before opening the solenoid valve 22 equals the preset value inside the control device 28, the corresponding solenoid valve 22 is closed to achieve precise feeding into the feed pipe 14. By using multiple sets of solenoid valves 22 and feed pipes 21 in cooperation, various different materials can be accurately fed into the feed pipe 14 to achieve efficient proportioning.

[0051] After the materials are proportioned, the moving cylinder 26 drives the sliding plate 24 to slide the carrying plate 25, connecting the connecting port 241 with the feed pipe 14 and the feed inlet 13. The carrying plate 25 abuts against the inner wall of the feed pipe 14 to scrape the material on the carrying plate 25 to the connecting port 241. The pushing plate 32 drives the sliding roller 34 to drive the rotating shaft 35 and the pushing plate 32 to push the material adhering to the inner wall of the feed pipe 14. After the pushing plate 32 passes through the feed inlet 13, it abuts against the scraper rope 38. The rotating motor 36 drives the pushing plate 32 to rotate, so that the scraper scrapes off the material adhering to the bottom of the pushing plate 32. In addition, the shock absorber 39 shocks the scraper rope 38 to reduce material loss.

[0052] The grinding motor 43 drives the grinding roller 41 and grinding ball 44 to rotate relative to the machine body 1 to grind the material that falls into the grinding chamber 11. Finally, the ground material flows into the collection box 12 through the gap between the grinding disc 42 and the inner wall of the grinding chamber 11 for collection, thereby realizing automated coating proportioning and grinding, thus improving the grinding efficiency of the coating.

[0053] This application also discloses a grinding method for a grinding mill used in paint production, comprising the following steps: Ingredient mixing: Ingredient mixing component 2 automatically mixes the raw materials inside different storage bins 15 into the feed pipe 14; Pushing: The pushing component 3 pushes the proportioned material inside the feed pipe 14 into the grinding chamber 11; Grinding: Grinding component 4 fully grinds the material inside grinding chamber 11; Discharge: The ground material falls into the collection box 12 for collection. The collection box 12 is then pulled out to remove the ground coating.

[0054] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application.
