Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, specifically to a vertical, anti-jamming three-roller material grinding equipment. Background Technology

[0002] Grinding equipment is an industrial equipment that uses mechanical forces, such as shearing, extrusion, and friction, to refine, disperse, or mix material particles. It is widely used in chemical, pharmaceutical, food, electronics, and building materials industries. Roller grinding equipment refers to grinding through the relative movement and gap extrusion between rollers. Three-roller material grinding equipment is a device that achieves precise grinding and dispersion of materials through the speed difference and gap extrusion of three rollers. It mainly uses shearing force and friction to refine material particles, and is especially suitable for slurries or pastes with high viscosity and high fineness requirements. It has a good grinding effect on materials with fluidity and adhesion. During the grinding process, when the rollers squeeze and shear the material, the material will adhere to the surfaces of both rollers at the same time. During the squeezing process, material is prone to dripping, causing material to accumulate inside the equipment and resulting in jamming. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides the following technical solution: The frame has a grinding chamber fixedly installed on its top and a motor fixedly installed on its outer side. A pulley is fixedly installed on the output end of the motor, and a belt is installed on the inner wall of the pulley. A roller milling mechanism is installed inside the grinding chamber and is connected to a belt drive. A material guiding mechanism is installed outside the grinding chamber and is used to discharge the material that has been ground. A limiting mechanism is installed on the top of the grinding chamber; A bottom baffle is fixedly installed on the bottom side of the inner wall of the grinding chamber away from the material guiding mechanism. An arc groove is formed on the top side of the bottom baffle away from the material guiding mechanism, and the top side of the bottom baffle near the material guiding mechanism is a gradually downward sloping surface. Side baffles are fixedly installed on both sides of the top of the bottom baffle's sloping surface, and a scraper is fixedly installed on the top of the bottom baffle. Through the cooperation of the scraper and the bottom baffle, after the scraper removes material from the surface of the feed roller, it accumulates on the top of the sloping surface of the bottom baffle. Utilizing the fluidity of the material and the sloping surface, it flows downwards, gradually approaching the grinding roller. A distribution plate blocks the material, allowing it to be gradually driven by the grinding roller for further grinding. This prevents material from adhering to the surface of the feed roller and accumulating inside, causing material jamming, during the grinding process. Simultaneously, in conjunction with the bottom guide plate, the material squeezed and dripping between the grinding roller and the discharge roller is smoothly discharged, avoiding material jamming. The scraper is located at the connection position of the arc groove and the inclined surface of the bottom baffle, and a groove is opened on the top of the bottom baffle near the material guiding mechanism. A rubber pad is engaged in the groove of the bottom baffle, and a material distribution plate is slidably installed in the groove of the bottom baffle. Through the cooperation of the rubber pad and the material distribution plate, the material distribution plate does not contact the grinding roller, while ensuring that the material adheres to the surface of the grinding roller, it limits the thickness of the material adhered to the surface of the grinding roller. This avoids that too much material adheres to the surface of the grinding roller, which would cause a large amount of material to drip during the squeezing and shearing between the grinding roller and the discharge roller, affecting the grinding of the material. The bottom guide plate is fixedly installed on the side of the bottom baffle near the material guiding mechanism.

[0004] Preferably, the roller mill mechanism includes a drive shaft rotatably mounted inside the grinding chamber. A driven wheel is fixedly mounted at one end of the drive shaft, and the groove of the driven wheel is connected to a belt drive. A gear one is fixedly mounted at the outer end of the drive shaft near the driven wheel, and a gear two is fixedly mounted at the outer end of the drive shaft away from the driven wheel. A feed shaft and a discharge shaft are rotatably mounted on the inner wall of the grinding chamber. The discharge shaft and the feed shaft are located on opposite sides of the drive shaft, with the discharge shaft located on the side closer to the guiding mechanism. A reduction gear is fixedly mounted at the end of the feed shaft near the driven wheel, and an acceleration gear is fixedly mounted at the end of the discharge shaft away from the driven wheel.

[0005] Preferably, the accelerating gear meshes with gear two, and the reducing gear meshes with gear one. The number of teeth on the accelerating gear is less than the number of teeth on gear two, and the number of teeth on the reducing gear is greater than the number of teeth on gear one. A feeding roller is fixedly installed on the outer side of the feeding shaft. Through the meshing of gear one and the reducing gear, and in conjunction with the meshing of gear two and the accelerating gear, the difference in the number of teeth creates a speed difference between the feeding roller, the grinding roller, and the discharge roller. This speed difference generates shearing force during the grinding process, which, combined with the squeezing between the rollers, improves the grinding effect on the material. A grinding roller is fixedly installed on the outer side of the transmission shaft, and a discharge roller is fixedly installed on the outer side of the discharge shaft. The bottom of the outer side of the feeding roller is rotatably adapted to the arc groove of the bottom baffle. The top of the scraper is in contact with the outer side of the feeding roller, and the top of the separating plate does not contact the outer side of the grinding roller.

[0006] Preferably, the limiting mechanism includes end blocks, which are fixedly installed on both sides of the top of the grinding chamber, and a threaded shaft is rotatably installed between the end blocks. A threaded hole block is threadedly connected to the outer side of the threaded shaft, and a limiting block is fixedly installed at the bottom of the threaded hole block. The limiting block is symmetrically installed along the center of the axis of the grinding chamber, and an arc groove is opened at the bottom of the limiting block. An anti-spill plate is fixedly installed on the side of the top of the grinding chamber away from the material guiding mechanism. Through the cooperation of the anti-spill plate and the limiting block, the material between the feed roller and the grinding roller is restricted during the feeding process, so as to prevent the free-flowing material from flowing and spreading to the surroundings when it cannot drive the grinding in time, which would prevent the material from smoothly entering the grinding position. A sliding groove is opened on the outer side of the anti-spill plate, and one end of the limiting block slides and adapts to the sliding groove of the anti-spill plate. The opposite surface of the limiting block is an inclined surface that slopes inward from top to bottom. A rotating wheel is fixedly installed at one end of the threaded shaft.

[0007] Preferably, the material guiding mechanism includes connecting plates, which are fixedly installed at both ends of the outer side of the grinding chamber. A guide plate is fixedly installed between the connecting plates. One end of the guide plate is tightly fitted to the outer side of the discharge roller, and the other end of the guide plate is inclined downwards. Side guide plates are fixedly installed on both sides of the top of the guide plate. Through the cooperation of the guide plate and the inclined guide chamber, the guide plate scrapes and discharges the material on the surface of the discharge roller, allowing the ground material to be discharged by the guide plate. Material that has not undergone complete grinding is guided by the bottom guide plate to the collection trough, and then discharged by… The guide tube at the bottom of the inclined guide chamber leads out the material separately, and also separately discharges the material that drips inside to prevent the material from getting stuck inside and causing blockage. An anti-overflow plate is fixedly installed on the top of the side guide plate away from the discharge roller. A material collection trough is fixedly installed between the connecting plates, and the bottom of the material collection trough has an empty groove. The side of the material collection trough near the discharge roller is tightly fitted to one end of the bottom guide plate. An inclined guide chamber is fixedly installed at the bottom of the material collection trough, and the material collection trough is located below the guide plate. A guide tube is fixedly installed at the bottom of the material collection trough.

[0008] This invention provides a vertical, anti-jamming three-roller material grinding device. It has the following beneficial effects: I. This vertical anti-jamming three-roller material grinding equipment uses a scraper and a bottom baffle to scrape off the material from the surface of the feed roller, causing it to accumulate on the top of the inclined surface of the bottom baffle. Utilizing the fluidity of the material and the inclined surface, it flows downwards at an angle, gradually approaching the grinding roller. The material is then blocked by a distribution plate, allowing it to be gradually driven by the grinding roller for further grinding. This prevents material from adhering to the surface of the feed roller and accumulating inside, causing jamming, during the grinding process. Simultaneously, in conjunction with the bottom guide plate, it smoothly discharges the material squeezed and dripping between the grinding roller and the discharge roller, preventing jamming.

[0009] Second, this vertical anti-jamming three-roller material grinding equipment, through the cooperation of rubber pads and distribution plates, utilizes the non-contact between the distribution plates and the grinding rollers to ensure that the material adheres to the surface of the grinding rollers while limiting the thickness of the material adhering to the surface of the grinding rollers. This avoids excessive material adhering to the surface of the grinding rollers, which would cause a large amount of material to drip off during the squeezing and shearing between the grinding rollers and the discharge rollers, thus affecting the grinding of the material.

[0010] Third, this vertical anti-jamming three-roller material grinding equipment, through the meshing of gear one with the reduction gear, and the meshing of gear two with the acceleration gear, utilizes the difference in the number of teeth to create a speed difference between the feed roller, grinding roller and discharge roller. The speed difference generates shearing force during the grinding process, which, combined with the squeezing between the rollers, improves the grinding effect on the material.

[0011] Fourth, this vertical anti-jamming three-roller material grinding equipment, through the cooperation of anti-spill plate and limiting block, restricts the material between the feed roller and the grinding roller during the feeding process, to prevent the free-flowing material from flowing and spreading to the surroundings when it cannot be driven to grind in time, thus preventing the material from smoothly entering the grinding position.

[0012] 5. This vertical anti-jamming three-roller material grinding equipment, through the cooperation of the guide plate and the inclined guide bin, uses the guide plate to scrape and discharge the material on the surface of the discharge roller, so that the material that has been ground is discharged by the guide plate, and the material that has not been fully ground is guided by the bottom guide plate to the collection trough and discharged through the guide tube at the bottom of the inclined guide bin, thus separating and discharging the material. At the same time, the material dripping inside is discharged separately to prevent the material from getting stuck inside and causing blockage. Attached Figure Description

[0015] 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.

[0016] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution: The frame 1 has a grinding chamber 6 fixedly installed on its top, and a motor 5 fixedly installed on the outside of the frame 1. A pulley 7 is fixedly installed at the output end of the motor 5, and a belt 8 is installed on the inner wall of the pulley 7. The roller grinding mechanism 3 is installed inside the grinding chamber 6 and is connected to the belt 8 for transmission. The material guiding mechanism 2 is installed on the outside of the grinding chamber 6 and is used to discharge the material that has been ground. Limiting mechanism 4 is installed on the top of grinding chamber 6; A bottom baffle 9 is fixedly installed on the bottom side of the inner wall of the grinding chamber 6, away from the material guiding mechanism 2. An arc groove is formed on the top side of the bottom baffle 9 away from the material guiding mechanism 2, and the top side of the bottom baffle 9 near the material guiding mechanism 2 is a gradually downward sloping surface. Side baffles 10 are fixedly installed on both sides of the top of the sloping surface of the bottom baffle 9, and a scraper 12 is fixedly installed on the top of the bottom baffle 9. The scraper 12 is located at the connection between the arc groove and the sloping surface of the bottom baffle 9. The bottom baffle 9 inside the grinding chamber 6, in conjunction with the scraper 12, scrapes the surface of the feed roller 303 during the grinding process, causing the material adhering to the surface of the feed roller 303 to fall onto the sloping surface at the top of the bottom baffle 9, allowing the material to move along the sloping surface. The material flows downwards at an angle and is blocked by the distribution plate 13, causing it to accumulate on the slope. A groove is provided on the top of the bottom baffle 9 near the guide mechanism 2. A rubber pad 14 is engaged in the groove of the bottom baffle 9, and the distribution plate 13 is slidably installed in the groove of the bottom baffle 9. During the accumulation process, the material gradually contacts the grinding roller 301, causing the grinding roller 301 to drive the accumulated material again and grind it. At the same time, the grinding roller 301 and the discharge roller 302 squeeze and shear the material, causing it to drip. When the material drips, it falls on the top of the bottom guide plate 11, which guides the dripping material. The bottom guide plate 11 is fixedly installed on the side of the bottom baffle 9 near the guide mechanism 2.

[0017] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figure 6As shown, the roller mill mechanism 3 includes a drive shaft 304, which is rotatably mounted inside the grinding chamber 6. A driven wheel 305 is fixedly mounted at one end of the drive shaft 304, and the groove of the driven wheel 305 is connected to the belt 8 for transmission. A gear 306 is fixedly mounted on the outer side of the drive shaft 304 near the driven wheel 305, and a gear 310 is fixedly mounted on the outer side of the drive shaft 304 away from the driven wheel 305. A feed shaft 308 and a discharge shaft 307 are rotatably mounted on the inner wall of the grinding chamber 6, located on opposite sides of the drive shaft 304. In the roller mill mechanism 3, the belt 8 drives the driven wheel 305 to rotate, which in turn drives the drive shaft 304 to rotate. During this rotation, the driven wheel 305 drives the gear 310 to rotate. Gear 306 and gear 310, through the meshing of gear 306 and reduction gear 309, and the meshing of gear 310 and acceleration gear 311, drive the feed shaft 308 and discharge shaft 307 to rotate during rotation due to the difference in the number of teeth. This causes the feed roller 303 and discharge roller 302 to rotate, resulting in a speed difference between the feed roller 303 and discharge roller 302 and the grinding roller 301. The speed difference is used to squeeze and shear the material between the rollers, thus achieving grinding of the material. The discharge shaft 307 is located on the side close to the guide mechanism 2. The reduction gear 309 is fixedly installed at the end of the feed shaft 308 near the driven wheel 305, and the acceleration gear 311 is fixedly installed at the end of the discharge shaft 307 away from the driven wheel 305.

[0018] Accelerating gear 311 meshes with gear two 310, and reducing gear 309 meshes with gear one 306. The number of teeth on accelerating gear 311 is less than the number of teeth on gear two 310, and the number of teeth on reducing gear 309 is greater than the number of teeth on gear one 306. A feeding roller 303 is fixedly installed on the outer side of the feeding shaft 308, and a grinding roller 301 is fixedly installed on the outer side of the transmission shaft 304. During the rotation of the material between the feeding roller 303 and the grinding roller 301, the grinding roller 301 rotates counterclockwise, while both the feeding roller 303 and the discharge roller 302 rotate clockwise. During the rotation of the grinding roller 301, the material between the feeding roller 303 and the material between the grinding roller 301 and the material between the feeding roller 302 and the material between the grinding roller 301 and the material between the grinding roller 301 and the material between the grinding roller 302 and the material between the grinding roller 301 and the material between the grinding roller 303 and the material between the grinding roller 301 and the material between the grinding roller 302 ...1 and the material between the grinding roller 302 and the material between the grinding roller 301 and the material between the grinding roller 302 and the material between the grinding roller 301 and the material between the grinding roller 3 The material is gradually driven downwards, and during the grinding process, some of the material adheres to the surface of the grinding roller 301. During the rotation, it gradually comes into contact with the discharge roller 302, grinding the material again. Then, it gradually adheres to the surface of the discharge roller 302. The discharge roller 302 and the guiding mechanism 2 cooperate to discharge the ground material and enter the next process. The discharge roller 302 is fixedly installed on the outside of the discharge shaft 307. The bottom of the outside of the feed roller 303 is adapted to the arc groove of the bottom baffle 9. The top of the scraper 12 is connected to the outside of the feed roller 303. The top of the dividing plate 13 does not contact the outside of the grinding roller 301.

[0019] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 7 to 9As shown, the limiting mechanism 4 includes end blocks 42, which are fixedly installed on both sides of the top of the grinding chamber 6. A threaded shaft 45 is rotatably installed between the end blocks 42. A threaded hole block 43 is threadedly connected to the outer side of the threaded shaft 45. A limiting block 41 is fixedly installed at the bottom of the threaded hole block 43. The limiting block 41 is symmetrically installed along the center position of the axis of the grinding chamber 6, and an arc groove is opened at the bottom of the limiting block 41. By rotating the rotating wheel 44, the threaded shaft 45 is driven to rotate, so that the threaded shaft 45 rotates under the restriction of the end blocks 42. At the same time, the threaded connection between the threaded hole block 43 and the threaded shaft 45 is utilized. The screw hole block 43 drives the limiting block 41 to move, restricting the position when the material is introduced. A spill prevention plate 46 is fixedly installed on the side of the top of the grinding chamber 6 away from the material guiding mechanism 2. A sliding groove is opened on the outer side of the spill prevention plate 46. One end of the limiting block 41 is slidably adapted to the sliding groove of the spill prevention plate 46, and the opposite surface of the limiting block 41 is an inclined surface that slopes inward from top to bottom. When the limiting block 41 moves, the limiting block 41 slides along the sliding groove of the spill prevention plate 46. The material introduced is restricted by the cooperation between the limiting block 41 and the spill prevention plate 46. A rotating wheel 44 is fixedly installed on one end of the threaded shaft 45.

[0020] The material guiding mechanism 2 includes connecting plates 21, which are fixedly installed at both ends of the outer side of the grinding chamber 6. A guide plate 25 is fixedly installed between the connecting plates 21. One end of the guide plate 25 is tightly fitted to the outer side of the discharge roller 302, and the other end of the guide plate 25 is inclined downwards. Side guide plates 22 are fixedly installed on both sides of the top of the guide plate 25. Through the contact between the guide plate 25 and the discharge roller 302, the material that has been ground on the surface of the discharge roller 302 is scraped off during the clockwise rotation of the discharge roller 302. The scraped material accumulates on the top of the guide plate 25. Utilizing the flowability of the material and the inclination of the guide plate 25, the ground material is discharged downwards along the guide plate 25. During the discharge process, the side guide plates 22 cooperate with the anti-overflow plate 23 to prevent spillage. The material is guided and restricted. An anti-overflow plate 23 is fixedly installed on the top of the side guide plate 22 away from the discharge roller 302. A collection trough 27 is fixedly installed between the connecting plates 21. The bottom of the collection trough 27 has an empty slot. The side of the collection trough 27 near the discharge roller 302 is tightly fitted with one end of the bottom guide plate 11. The material that is ground and squeezed between the grinding roller 301 and the discharge roller 302 is guided by the bottom guide plate 11, so that the material is introduced into the collection trough 27 and then introduced into the inclined guide chamber 24 through the empty slot of the collection trough 27. Finally, it is discharged by the conduit 26, and discharged separately from the ground material to avoid mixing. The bottom of the collection trough 27 is fixedly installed with the inclined guide chamber 24, and the collection trough 27 is located below the guide plate 25. The bottom of the collection trough 27 is fixedly installed with the conduit 26.

[0021] In use, first adjust the limiting mechanism 4 to control the grinding and diffusion width of the material. Then, introduce the material to be ground into the roller mill mechanism 3 and start the motor 5 so that the motor 5 drives the roller mill mechanism 3 through the belt 8. The roller mill mechanism 3 grinds the material and cooperates with the material guiding mechanism 2 to control the discharge of the ground material.

[0022] In the roller mill mechanism 3, the belt 8 drives the driven wheel 305 to rotate, which in turn drives the transmission shaft 304 to rotate. During rotation, this drives gear one 306 and gear two 310. The meshing of gear one 306 with reduction gear 309, combined with the meshing of gear two 310 with acceleration gear 311, causes the feed shaft 308 and discharge shaft 307 to rotate due to the difference in the number of teeth. This, in turn, causes the feed roller 303 and discharge roller 302 to rotate, creating a speed difference between the feed roller 303 and discharge roller 302 and the grinding roller 301. This speed difference is used to squeeze and shear the material between the rollers, achieving the desired grinding effect. During the grinding of the material, the material between the feed roller 303 and the grinding roller 301 rotates. The grinding roller 301 rotates counterclockwise, while the feed roller 303 and the discharge roller 302 rotate clockwise. During the rotation of the grinding roller 301, the material between it and the feed roller 303 is gradually driven downwards. During the grinding process, some of the material adheres to the surface of the grinding roller 301 and gradually comes into contact with the discharge roller 302 during the rotation, grinding the material again. Subsequently, the material gradually adheres to the surface of the discharge roller 302. The discharge roller 302, in cooperation with the guiding mechanism 2, discharges the ground material to the next process.

[0023] During the grinding process, the bottom baffle 9 inside the grinding chamber 6, in conjunction with the scraper 12, scrapes the surface of the feed roller 303 during the grinding process, causing the material adhering to the surface of the feed roller 303 to fall onto the inclined surface at the top of the bottom baffle 9. The material flows downward along the inclined surface and is blocked by the distribution plate 13, causing the material to accumulate on the inclined surface. During the accumulation process, the material gradually contacts the grinding roller 301, causing the grinding roller 301 to drive the accumulated material again for grinding. At the same time, the grinding roller 301 and the discharge roller 302 squeeze and shear the material, causing the material to drip. When the material drips, it falls onto the top of the bottom guide plate 11, which guides the dripping material.

[0024] In the limiting mechanism 4, the rotating wheel 44 drives the threaded shaft 45 to rotate, so that the threaded shaft 45 rotates under the restriction of the end block 42. At the same time, the threaded connection between the threaded hole block 43 and the threaded shaft 45 causes the threaded hole block 43 to drive the limiting block 41 to move, thus limiting the position when the material is introduced. At the same time, when the limiting block 41 moves, it slides along the groove of the anti-spill plate 46. The material is restricted by the cooperation between the limiting block 41 and the anti-spill plate 46.

[0025] In the material guiding mechanism 2, through the contact between the guide plate 25 and the discharge roller 302, the material that has been ground on the surface of the discharge roller 302 is scraped off during the clockwise rotation of the discharge roller 302. The scraped material accumulates on the top of the guide plate 25. The material's fluidity and the inclination of the guide plate 25 are used to guide the ground material downwards along the guide plate 25. During the discharge process, the material is guided and restricted by the cooperation of the side guide plate 22 and the anti-overflow plate 23. At the same time, the material that is ground and squeezed and dripped between the grinding roller 301 and the discharge roller 302 is guided by the bottom guide plate 11 and introduced into the collection trough 27. The material is then introduced into the inclined guide chamber 24 through the empty slot of the collection trough 27 and finally discharged through the guide tube 26, separated from the ground material to avoid mixing.
