Description

Technical Field

[0001] This invention relates to the field of coating mixing technology, specifically a brake pad coating mixer. Background Technology

[0002] As a core component of the automotive braking system, brake pads' coating performance directly determines braking efficiency, noise control, and service life. The coating mixing process is a crucial step in brake pad production, requiring precise raw material proportioning and mixing technology to achieve a balance between frictional performance, mechanical strength, and high-temperature resistance. However, traditional mixing equipment often suffers from uneven dispersion and material performance loss when dealing with complex raw material systems due to differences in functional requirements at each mixing stage.

[0003] Existing horizontal mixing machines, such as the one proposed in patent application number "CN214862663U", include a main body, a discharge port, a mixing chamber, a top cover, a controller, a power cord, a reflux mechanism, a drive motor, a stirring roller, an electric push rod, and a blocking plate. By incorporating a reflux mechanism at the bottom of the main body, a piston can compress material at the bottom of the mixing chamber and reflux it back to the top of the mixing chamber through a transmission pipe, further improving the mixing effect between materials. Furthermore, during cleaning of the mixing chamber, the piston can drive the cleaning liquid to reflux up and down and clean the inner surface of the mixing chamber, saving water resources. By incorporating an auxiliary component at the lower end of the piston chamber, a push plate can transmit air into the mixing chamber through an air guide pipe, creating gaps between the material mixture and providing oxygen, while also improving airflow within the cleaned mixing chamber, facilitating drying.

[0004] However, in practical applications, the aforementioned patented technology still reveals some significant shortcomings. Its design, which uses a motor to directly drive the stirring rollers to mix the materials in the mixing tank, shows obvious limitations when handling the transition from dry to wet mixing. Specifically, when the material state changes from dry to wet mixing, the viscosity of the coating increases significantly. In this situation, the torque output of the motor at low speeds often decreases, resulting in insufficient torque. This can cause uneven mixing, making it difficult to meet the mixing requirements of high-viscosity materials, thus affecting the stability of the mixing effect and product quality.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] A brake pad coating mixer, wherein the mixer adjusts the rotation speed and torque of the stirring rod according to the dry or wet mixing state of the coating, such as... Figure 2 and Figure 3 As shown, the speed and torque of the stirring rod are changed by adjusting the mechanism, which is a type of paint mixing device.

[0023] like Figures 1-7 As shown, it includes a base 1, a mixing tank 2 is fixedly connected to the top of the base 1, a first stirring shaft 3 and a second stirring shaft 4 are rotatably connected to the two ends of the mixing tank 2 respectively, the first stirring shaft 3 passes through the inside of the second stirring shaft 4, an inner stirring blade 5 is fixedly connected to one end of the first stirring shaft 3 and the second stirring shaft 4, and a planetary carrier 6 is fixedly connected to one end of the first stirring shaft 3 and the second stirring shaft 4. Three tipping rods 7 are rotatably connected to the end of the planetary carrier 6, and the three tipping rods 7 are distributed in a ring around the planetary carrier 6. An adjustment mechanism is installed at one end of the mixing tank 2, which is used to drive the first mixing shaft 3 and the second mixing shaft 4 to rotate, and adjust the speed and torque according to the dry or wet mixing state; The mixing tank 2 is equipped with a magnetic coupling assembly, which is used to drive the tipping rod 7 to rotate, thereby enhancing the uniformity of material dispersion.

[0024] In use, firstly, when a large amount of solid particles and fiber materials are poured into the mixing tank 2, the adjustment mechanism is activated to drive the first stirring shaft 3 and the second stirring shaft 4 to rotate synchronously and control them to enter the dry mixing mode. At this time, the first stirring shaft 3 and the second stirring shaft 4 drive the planetary carrier 6 to drive the tipping rod 7 to slowly stir the raw materials inside the mixing tank 2, and use the magnetic coupling component to drive the tipping rod 7 to rotate, so that the tipping rod 7 flips the raw materials inside the mixing tank 2 towards the center. At the same time, the first stirring shaft 3 and the second stirring shaft 4 drive the inner stirring blades 5 to perform low-speed, high-torque mixing of the materials flipped in the mixing tank 2. Subsequently, after the solid particles and fiber materials inside the mixing tank 2 have been initially mixed, liquid resin is poured into the mixing tank 2. Then, the adjustment mechanism is activated, driving the first mixing shaft 3 and the second mixing shaft 4 to synchronously reverse at high speed, and controlling the first mixing shaft 3 and the second mixing shaft 4 to enter the wet mixing mode. At this time, the first mixing shaft 3 and the second mixing shaft 4 drive the planetary carrier 6 to drive the turning rod 7 to mix the liquid resin, fiber materials, and solid particles inside the mixing tank 2 at high speed. The turning rod 7 is driven to rotate by the magnetic coupling component. At the same time, the turning rod 7 turns the raw materials inside the mixing tank 2 towards the center. Meanwhile, the first mixing shaft 3 and the second mixing shaft 4 drive the inner mixing blades 5 to mix the turned raw materials in the mixing tank 2 at high speed and low torque. This allows for the adjustment of the speed and torque of the inner mixing blades 5 and the turning rod 7 according to the different mixing states of dry and wet mixing, so as to meet the different mixing requirements under the dry and wet mixing states of the materials and improve the stability of the mixing effect of the materials.

[0025] like Figures 3-7 As shown, the adjustment mechanism includes a bevel gear 19 fixedly connected to one end of the second stirring shaft 4, a bevel gear 20 fixedly connected to one end of the first stirring shaft 3 passing through the second stirring shaft 4, and a bevel gear 31 rotatably connected to one end of the stirring box 2. The bevel gear 321 meshes synchronously with the bevel gear 19 and the bevel gear 20 to form a reverse rotation transmission. A stirring assembly is installed at one end of the base 1, which is used to drive the bevel gear 321 to rotate in order to adjust the speed and torque of the bevel gear 321. The stirring assembly includes a stirring motor 12 fixedly connected to one end of the base 1. The output end of the stirring motor 12 is fixedly connected to a drive shaft 17. A drive gear 8 is sleeved on the drive shaft 17. An adjusting gear 11 is fixedly connected to one end of the drive gear 8 and is sleeved on one end of the drive shaft 17. A driven gear 9 that meshes with the drive gear 8 is fixedly connected to one end of the bevel gear 21, and a follower gear 10 is fixedly connected to one end of the bevel gear 21. An adjusting assembly is installed at one end of the base 1. This assembly is used to drive the adjusting gear 11 and the drive gear 8 to move together along the length of the drive shaft 17, thereby changing the meshing state of the adjusting gear 11 and the follower gear 10 to achieve the switching of torque output mode. Furthermore, the adjustment assembly includes a lifting rod 13 rotatably connected to one end of the adjustment gear 11, an electric push rod 14 fixedly connected to one end of the base 1, the output end of the electric push rod 14 fixedly connected to the lifting rod 13, and a guide assembly installed at one end of the drive shaft 17, which is used to pull the adjustment gear 11 and the drive gear 8 to rotate synchronously at all times. Furthermore, the guide assembly includes an adjusting slider 15 symmetrically fixedly connected inside the adjusting gear 11, and an adjusting groove 16 symmetrically opened at one end of the drive shaft 17, with the adjusting slider 15 slidably connected inside the adjusting groove 16. Furthermore, the inner stirring blade 5 is set as a spiral stirring blade, and the bottom of the stirring box 2 is provided with a discharge port 28, and the output end of the discharge port 28 is threadedly connected to a manual discharge valve 29. Furthermore, an arc-shaped heating chamber is provided at the bottom of the mixing tank 2, and an electric heating wire 26 is fixedly connected inside the arc-shaped heating chamber. A temperature sensor 27 is fixedly connected to one end of the first stirring shaft 3.

[0026] In use, first set the diameter ratio of the follower gear 10 to the adjusting gear 11, and the driving gear 8 to the driven gear 9 to 2:1, and set the temperature sensor to use Honeywell. In the HEL-700 series, while pouring a large amount of solid particles and fiber materials into the mixing tank 2, the electric push rod 14 is activated to pull the lifting rod 13 to slide, causing the lifting rod 13 to drive the adjusting gear 11 to slide along the length of the adjusting groove 16 until it meshes with the follower gear 10. At this time, the adjusting gear 11 drives the driving gear 8 to disengage from the driven gear 9. Subsequently, the stirring motor 12 is activated to drive the adjusting gear 11 to mesh with the follower gear 10, and the diameter difference between the follower gear 10 and the adjusting gear 11 is used to reduce the speed of the follower gear 10 and increase its torque. This allows the follower gear 10 to drive the bevel gear 3 21 to mesh synchronously with the bevel gear 20 and the bevel gear 19. In turn, the bevel gear 20 and the bevel gear 19 drive the first stirring shaft 3 and the second stirring shaft 4 to rotate slowly, respectively. In this way, the first stirring shaft 3 and the second stirring shaft 4 can drive the inner stirring blades 5 to mix the raw materials tumbling inside the mixing tank 2 at low speed and high torque, ensuring that the dry materials are mixed evenly.

[0027] After the dry materials are evenly mixed inside the mixing tank 2, liquid resin is poured in, and the electric actuator 14 is activated to push the lifting rod 13, which drives the adjusting gear 11 to slide along the length of the adjusting groove 16. At the same time, the adjusting gear 11 disengages from the follower gear 10, and the adjusting gear 11 drives the driving gear 8 to mesh with the driven gear 9. Then, the stirring motor 12 is activated to drive the driving gear 8 to rotate, and the driving gear 8 meshes with the driven gear 9. The difference in diameter between the driving gear 8 and the driven gear 9 increases the speed of the driven gear 9, which drives the bevel gear 21 to rotate at high speed. The bevel gear 21 meshes synchronously with the bevel gear 20 and the bevel gear 19. This will cause the bevel gear 20 and the bevel gear 19 to drive the first stirring shaft 3 and the second stirring shaft 4 to rotate at high speed, which in turn causes the first stirring shaft 3 and the second stirring shaft 4 to drive the inner stirring blades 5 to mix the raw materials inside the mixing tank 2 at high speed and low torque, in order to adapt to the fluidity of the materials in a wet state and ensure the stability of the mixing effect.

[0028] In addition, the temperature sensor 27 is set to monitor the temperature of the raw materials in the wet mixing state inside the mixing tank 2 in real time and transmit the monitoring data to the remote control center in real time. When the temperature of the raw materials in the wet mixing state inside the mixing tank 2 is detected to be low, the electric heating wire 26 is activated to heat the bottom of the mixing tank 2 and exchange heat with the raw materials in the wet mixing state inside the mixing tank 2 to increase the temperature of the raw materials in the wet mixing state. In this way, the temperature of the raw materials inside the mixing tank 2 will be maintained between 50-60°C to reduce viscosity, ensure that the liquid resin wets the surface of the fiber and solid filler, and improve the uniformity of liquid resin coating. After mixing is completed, the adjustment mechanism is activated to drive the first stirring shaft 3 and the second stirring shaft 4 to rotate the inner stirring blades 5 and the turning rod 7. This causes the turning rod 7 to turn the raw materials inside the mixing tank 2 towards the center. At the same time, the two inner stirring blades 5 are used to spirally stir inside the mixing tank 2 and push the raw materials into the lower feed port 28. Then, the manual discharge valve 29 is manually turned to open the discharge port 28 and guide the raw materials out, which facilitates the gathering of the raw materials inside the mixing tank 2 from the discharge ports 28 at both ends, thereby improving the discharge efficiency.

[0029] like Figure 3 and Figure 4 , Figure 6 , Figure 8 As shown, the magnetic coupling assembly includes three annular mounting slots 22 evenly spaced at one end of the planetary carrier 6. The hinged end of the tipping rod 7 and the planetary carrier 6 passes through the interior of the annular mounting slots 22. A moving magnetic ring 23 is fixedly connected inside the annular mounting slots 22 and is fixedly sleeved around the tipping rod 7. An annular protective cover 24 is symmetrically fixedly connected inside the mixing tank 2. An outer magnetic ring 25 is fixedly connected inside the annular protective cover 24 and is sleeved around the planetary carrier 6. The ratio of the number of pole pairs of the outer magnetic ring 25 to the moving magnetic ring 23 is 1:3, so as to drive the tipping rod 7 to rotate three times when it revolves once, thereby enhancing the material shearing and dispersion effect.

[0030] In use, when the adjustment mechanism is activated, the first stirring shaft 3 and the second stirring shaft 4 are driven to rotate, and the inner stirring blades 5 are driven to stir and mix the raw materials inside the mixing tank 2. At the same time, the first stirring shaft 3 and the second stirring shaft 4 drive the planetary carrier 6 to rotate, and the planetary carrier 6 drives the turning rod 7 and the moving magnetic ring 23 to rotate. Simultaneously, as the magnetic field coupling between the moving magnetic ring 23 and the outer magnetic ring 25 causes the turning rod 7 to rotate on its own axis, and according to the pole pair ratio of the outer magnetic ring 25 and the moving magnetic ring 23, the planetary carrier 6 drives the turning rod 7 to revolve once, while the moving magnetic ring 23 drives the turning rod 7 to rotate three times. This effectively improves the turning efficiency of the turning rod 7 in turning the materials inside the mixing tank 2 and enhances the shearing and dispersion effect of the materials.

[0031] like Figure 1 and Figure 3 , Figure 4 , Figure 6 As shown, a storage platform 30 is fixedly connected to the top of the mixing tank 2. Storage troughs 31 are symmetrically opened on the top of the storage platform 30. Feed inlets 32 are symmetrically opened on the top of the mixing tank 2. A double-headed discharge valve 33 connected to the bottom of the storage platform 30 and communicating with the output ends of the two storage troughs 31 is fixedly connected. A feeding pipe 39 is fixedly connected to the input end of one feeding inlet 32. The output end of the double-headed discharge valve 33 extends into the interior of the feeding pipe 39, and a flow meter 34 is fixedly connected to the input end of the double-headed discharge valve 33. A feeding auger 35 is rotatably connected inside the feeding pipe 39. A synchronization component is installed at one end of the first mixing shaft 3, which is used to drive the feeding auger 35 to rotate, thereby pushing the raw material through the feeding pipe 39 into the interior of the feeding inlet 32. The synchronization component includes a drive wheel 36 fixedly connected to one end of the first stirring shaft 3, a drive wheel 37 fixedly connected to one end of the feeding auger 35, and a drive belt 38 sleeved around the drive wheel 36 and the drive wheel 37.

[0032] When in use, first set the double-headed feeding valve 33 to the rotary diverter valve of SchuF Rotary Diverter Valve (RDV-2 series), pour short fibers into the inside of one storage tank 31, and pour long fibers into the inside of another storage tank 31. Then, add solid granular filler, additives and binders into the inside of the base 1 through the feed port 32. Then, the double-headed discharge valve 33 is activated to remove the obstruction of the output end of one of the storage tanks 31, allowing the short fibers inside the storage tank 31 to flow into the feed pipe 39. At the same time, a flow meter 34 is set to monitor the flow rate of the short fibers entering the feed pipe 39. When the regulating mechanism is activated to drive the first stirring shaft 3 to rotate, it is ensured that the first stirring shaft 3 drives the first transmission wheel 36 to rotate synchronously. This will cause the first transmission wheel 36 to drive the second transmission wheel 37 to rotate through the transmission belt 38, and further cause the second transmission wheel 37 to drive the feed auger 35 to rotate, pushing the short fibers inside the feed pipe 39 through the inlet 32 ​​into the mixing tank 2 for mixing and mixing, so as to reduce the agglomeration phenomenon.

[0033] Subsequently, when the raw materials inside the mixing tank 2 reach a wet mixed state, the double-headed discharge valve 33 is activated to remove the obstruction to the output end of the other storage tank 31, allowing the long fibers inside the storage tank 31 to flow into the interior of the feeding pipe 39. At the same time, a flow meter 34 is set to monitor the flow rate of the long fibers entering the interior of the feeding pipe 39, and when the regulating mechanism is activated to drive the first stirring shaft 3 to rotate, it is ensured that the first stirring shaft 3 drives the transmission wheel 36 to rotate synchronously. This will cause the transmission wheel 36 to drive the transmission wheel 37 to rotate through the transmission belt 38, and further cause the transmission wheel 37 to drive the feeding auger 35 to rotate, pushing the long fibers inside the feeding pipe 39 through the inlet 32 ​​into the interior of the mixing tank 2 for mixing, so as to avoid the liquid resin from prematurely wetting the surface of the long fibers and causing embrittlement.

[0034] The working principle of the brake pad coating mixer provided by this invention is as follows: First, short fibers are poured into one storage tank 31, and long fibers into another storage tank 31. Next, the double-headed discharge valve 33 is activated to remove the obstruction to the output end of one storage tank 31, allowing the short fibers inside the storage tank 31 to flow into the feed pipe 39. Then, after pouring a large amount of solid particles and additives into the mixing tank 2, the electric actuator 14 is activated to drive the adjusting gear 11 to slide along the length of the adjusting chute 16 until it meshes with the follower gear 10. Simultaneously, the adjusting gear 11 disengages the driving gear 8 from the driven gear 9. At this point, the mixing motor 12 is activated to engage the adjusting gear 11 with the follower gear 10, and the diameter difference between the follower gear 10 and the adjusting gear 11 is used to reduce the rotational speed of the follower gear 10 and increase its speed. The torque of the follower gear 10 is applied, which causes the follower gear 10 to drive the bevel gear 3 21 to mesh synchronously with the bevel gear 20 and the bevel gear 19. The bevel gear 20 and the bevel gear 19 then drive the first stirring shaft 3 and the second stirring shaft 4 to rotate slowly in opposite directions. This causes the first stirring shaft 3 and the second stirring shaft 4 to drive the inner stirring blades 5 to mix the raw materials inside the mixing box 2 at low speed and high torque. At the same time, the first stirring shaft 3 drives the transmission wheel 36 to rotate synchronously, so that the transmission wheel 36 drives the transmission wheel 37 to rotate through the transmission belt 38. The transmission wheel 37 then drives the feeding auger 35 to rotate, pushing the short fibers inside the feeding pipe 39 through the feed inlet 32 ​​into the mixing box 2 for mixing. Subsequently, when liquid resin is poured into the mixing tank 2 to reach a wet mixing state, the double-headed discharge valve 33 is activated to remove the obstruction of the output end of the other storage tank 31, allowing the long fibers inside the storage tank 31 to flow into the interior of the feeding pipe 39; similarly, when the adjustment mechanism is activated to drive the first stirring shaft 3 to rotate, it is ensured that the transmission wheel 37 drives the feeding auger 35 to rotate, pushing the long fibers inside the feeding pipe 39 through the inlet 32 ​​into the interior of the mixing tank 2 for mixing; Then, the electric actuator 14 is activated to push the lifting rod 13, which in turn drives the adjusting gear 11 to slide along the length of the adjusting groove 16. At the same time, the adjusting gear 11 disengages from the follower gear 10 and drives the driving gear 8 to mesh with the driven gear 9. This activates the stirring motor 12, which drives the driving gear 8 to rotate and meshes with the driven gear 9. The difference in diameter between the driving gear 8 and the driven gear 9 increases the speed of the driven gear 9, causing the driven gear 9 to drive the bevel gear 21 to rotate at high speed. Simultaneously, the bevel gear 21 meshes synchronously with the bevel gear 20 and the bevel gear 19. This causes the bevel gear 20 and the bevel gear 19 to drive the first stirring shaft 3 and the second stirring shaft 4 to rotate at high speed, which in turn causes the first stirring shaft 3 and the second stirring shaft 4 to drive the inner stirring blades 5 to mix the raw materials inside the mixing box 2 at high speed and low torque. When the adjustment mechanism is activated, it drives the first stirring shaft 3 and the second stirring shaft 4 to rotate, and drives the inner stirring blades 5 to stir and mix the raw materials inside the mixing tank 2. At the same time, the first stirring shaft 3 and the second stirring shaft 4 drive the planetary carrier 6 to rotate, and the planetary carrier 6 drives the turning rod 7 and the moving magnetic ring 23 to rotate. Simultaneously, as the magnetic field coupling between the moving magnetic ring 23 and the outer magnetic ring 25 causes the turning rod 7 to rotate, and according to the pole pair ratio of the outer magnetic ring 25 and the moving magnetic ring 23, the planetary carrier 6 drives the turning rod 7 to revolve once, while the moving magnetic ring 23 drives the turning rod 7 to rotate three times, which effectively improves the turning efficiency of the turning rod 7 in turning the materials inside the mixing tank 2.
