Description

Technical Field

[0001] The present invention relates to the technical field of vertical grinding machines, and particularly to a vertical grinding machine with a grinding degree adjustment function. Background Art

[0002] The working principle of a vertical grinding machine is that a liquid-solid mixture that has undergone pre-dispersion and wetting treatment is fed into the grinding cylinder by a feeding pump through the bottom feeding valve of the grinding cylinder and is stirred by a high-speed rotating disperser together with the grinding medium in the grinding cylinder, so that strong shear impacts are generated between the solid particles in the material and the grinding medium, achieving the purpose of grinding fine particles and dispersing aggregates. The solid-liquid suspension after grinding and dispersion flows out through the screen at the top of the grinding cylinder. It is a high-efficiency grinding device widely used in industries such as coatings, dyes, inks, pesticides, tapes, papermaking, leather, and chemicals, and has the advantages of simple structure, stable start, high continuous production efficiency, convenient color change, easy cleaning, and simple operation.

[0003] In existing equipment, the grinding degree of a vertical grinding machine is determined by the material characteristics of the abrasive itself and the quantity of the abrasive, which results in a constant grinding degree of the vertical grinding machine. For some usage scenarios that require precise and fine grinding degrees, manual replacement of the abrasive is needed, which not only requires disassembling the grinding machine but also cannot guarantee that no impurities will enter the grinding machine during the process of adding the abrasive, greatly reducing the breadth of the usage scenarios and the grinding efficiency of the grinding machine. Summary of the Invention

[0004] The purpose of the present invention is to provide a vertical grinding machine with a grinding degree adjustment function to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A vertical grinding machine with a grinding degree adjustment function includes a chassis, a first servo motor, a first transmission seat, a feeding pipe, a liquid pumping pump, a grinding mechanism, and a detection mechanism. The chassis is fixedly connected to the first servo motor, the output end of the first servo motor is in transmission connection with the first transmission seat, the chassis is fixedly connected to the feeding pipe, the liquid pumping pump, the grinding mechanism, and the detection mechanism, and the first transmission seat is in transmission connection with the grinding mechanism.

[0006] This grinding machine is used to grind and refine the pre-wetted and pre-treated material into a slurry state. According to the degree of grinding required, the first servo motor outputs a reverse torque to separate a part of the abrasive according to the required grinding degree, and inputs the pre-treated material into the grinding mechanism through the feeding pipe. The first servo motor outputs a forward torque, and the grinding mechanism mixes the wet pre-treated material with part of the abrasive and rotates for grinding. Through the shear collision between the material and the abrasive, the material finally presents the required viscosity and roughness in a slurry state. After the detection mechanism detects whether the roughness meets the requirements, the liquid pumping pump pumps out the ground slurry.

[0007] Further, the grinding mechanism includes a housing, a main shaft, a stirring and distributing mechanism, a covering mechanism, and a filter screen. The housing is fixedly connected to the chassis, the main shaft is rotatably connected to the housing, the main shaft is drivingly connected to the first servo motor, the stirring and distributing mechanism is drivingly connected to the main shaft, the stirring and distributing mechanism is fixedly connected to the covering mechanism, a first slide rail is provided on the housing, the first slide rail is slidably connected to the covering mechanism, and the filter screen is fixedly connected to the covering mechanism.

[0008] According to the degree of grinding required, the first servo motor outputs a reverse torque to the main shaft, the stirring and distributing mechanism rotates in the reverse direction, grabs a part of the abrasive, the stirring and distributing mechanism transmits the torque to the covering mechanism, the covering mechanism descends to cover the upper part of the stirring and distributing mechanism, separating the abrasive, and then the material is injected into the housing. The first servo motor outputs a positive torque to the main shaft, the stirring and distributing mechanism rotates in the positive direction, so that the pre-wetted material is mixed with a part of the abrasive for rotary grinding. Through the shear collision between the material and the abrasive, the material finally presents the required viscosity, roughness, and slurry state.

[0009] Further, the stirring and distributing mechanism includes an outer bottom cylinder, an inner cylinder, arc plates, a linkage mechanism, and a second servo motor. The outer bottom cylinder is fixedly connected to the inner cylinder, the covering mechanism, and the filter screen. The inner cylinder is drivingly connected to the main shaft. There are several groups of arc plates, and several groups of arc plates are evenly distributed along the circumference of the outer bottom cylinder. Several groups of arc plates are fixedly connected to the linkage mechanism, and several groups of arc plates are rotatably connected to the outer bottom cylinder. The second servo motor is fixedly connected to the outer bottom cylinder, and the output end of the second servo motor is drivingly connected to the linkage mechanism.

[0010] It is set that the clockwise rotation towards the outer arc surface of the arc plate is the positive direction, and the counterclockwise rotation is the negative direction. The second servo motor determines the amount of abrasive to be separated according to the grinding degree to be adjusted, outputs the torque and transmits it to the arc plate through the linkage mechanism. The circumferentially evenly distributed arc plates rotate towards the outer arc surface. The main shaft transmits a reverse torque to the inner cylinder, and an included angle space is formed between the arc plate and the outer bottom cylinder. By rotating the outer bottom cylinder in the reverse direction, a part of the abrasive is carried by the included angle space. The proportion of the carried abrasive is determined by the rotation of the arc plate. At the same time, the outer bottom cylinder transmits the torque to the covering mechanism, and the covering mechanism slides down along the first slide rail. After the second servo motor outputs a positive torque, the material grabbed by the arc plate is thrown to the inner wall of the covering mechanism, and the remaining abrasive and the material are mixed and ground under the drive of the arc plate, achieving the effect of adjusting the final grinding degree.

[0011] Further, the linkage mechanism includes a second transmission seat, a transmission seat rod, and a third transmission seat. The second transmission seat is drivingly connected to the output end of the second servo motor. There are several groups of transmission seat rods and third transmission seats, and several groups of transmission seat rods and third transmission seats are evenly distributed along the circumference of the outer bottom cylinder. The second transmission seat is drivingly connected to the transmission seat rod through a belt, the transmission seat rod is drivingly connected to the third transmission seat through a belt, and several groups of third transmission seats are fixedly connected to the arc plate.

[0012] The second servo motor outputs torque to the second transmission seat. The second transmission seat is in belt drive with the circumferentially evenly distributed transmission seat rods. The belt drives the transmission seat rods to rotate on the outer bottom cylinder. The circumferentially evenly distributed transmission seat rods correspond to the third transmission seats one by one. The transmission seat rods drive the third transmission seats to rotate through the belt, transmit the torque to the arc plate, and drive the arc plate to rotate.

[0013] Further, the cover material mechanism includes a top shell, a connecting rod, and an anti-twist mechanism. The connecting rod is fixedly connected to the outer bottom cylinder, and the anti-twist mechanism is fixedly connected to the connecting rod. The top shell is provided with an internal thread hole and a convex block. The anti-twist mechanism is threadedly connected to the internal thread hole, and the convex block is slidably connected to the first slide rail.

[0014] When the stirring and distributing mechanism rotates in the reverse direction, torque is transmitted to the anti-twist mechanism through the connecting rod. The anti-twist mechanism rotates and, through threaded connection with the internal thread hole, causes the top shell to slide downward along the first slide rail; when the stirring and distributing mechanism rotates in the forward direction, due to the structure of the anti-twist mechanism itself, the torque transmitted by the connecting rod is offset, the anti-twist mechanism no longer rotates, and the cover material mechanism does not move upward, causing the separated abrasive to leak out.

[0015] Further, the anti-twist mechanism includes an external thread cylinder, an internal groove, a compression spring, an arc tooth part, and a tooth ring. The tooth ring is fixedly connected to the connecting rod, the tooth ring is in tooth surface engagement with the arc tooth part, the compression spring is fixedly connected to both the external thread cylinder and the arc tooth part, the internal groove is fixedly connected to the external thread cylinder, the arc tooth part is slidably connected to the internal groove, and the external thread cylinder is threadedly connected to the internal thread hole.

[0016] When the connecting rod transmits positive torque, in a top-down view, the tooth ring rotates counterclockwise. The arc tooth part is in tooth surface engagement with the tooth ring. Through the engagement of the helical tooth surface, the rotation of the tooth ring is converted into the sliding of the arc tooth part along the internal groove. The arc tooth part is reset under the action of the compression spring, and the external thread cylinder does not rotate; when the connecting rod transmits reverse torque, the arc tooth part abuts against the tooth back of the tooth ring, and the external thread cylinder is driven to rotate through the arc tooth part and the internal groove.

[0017] Further, the detection mechanism includes a flow channel, a housing, an impeller, a tooth head rod, and a resistance adjustment mechanism. The flow channel is fixedly connected to the outer shell, the housing is fixedly connected to both the flow channel and the resistance adjustment mechanism, the impeller is rotatably connected to the housing, the tooth head rod is fixedly connected to the impeller, and the resistance adjustment mechanism is in tooth surface engagement with the tooth head rod.

[0018] The material that has completed grinding and pulping enters the housing through the flow channel. The slurry materials with different grinding degrees drive the impeller to rotate at different speeds. The impeller transmits the torque to the tooth head rod. The tooth head rod is in tooth surface engagement with the resistance adjustment mechanism, and the electrical signal fed back is changed through the resistance change value of the resistance adjustment mechanism to judge the state of the material pulping.

[0019] Further, the resistance adjusting mechanism includes a fixed seat, bevel gears, a worm, a worm seat, a second slide rail, a metal electric sheet, and a rheostat. The fixed seat, the second slide rail, and the rheostat are all fixedly connected to the housing. The bevel gear is rotatably connected to the fixed seat, and the bevel gear meshes with the tooth surface of the tooth head rod. The worm is fixedly connected to the bevel gear, and the worm is threadedly connected to the worm seat. The worm seat is slidably connected to the second slide rail. The metal electric sheet is fixedly connected to the worm seat, and the metal electric sheet is slidably connected to the rheostat.

[0020] The impeller transfers the torque to the tooth head rod. The tooth head rod meshes with the tooth surface of the bevel gear, driving the bevel gear to rotate. The bevel gear transfers the torque to the worm. Through the threaded fit between the worm and the worm seat, the rotation of the worm is converted into the reciprocating displacement of the worm seat along the second slide rail. The metal electric sheet fixed on the worm seat slides on the rheostat, changing the resistance of the rheostat.

[0021] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention designs a stirring and dividing mechanism. It is set that the clockwise rotation towards the outer arc surface of the arc plate is the forward direction, and the counterclockwise rotation is the reverse direction. The second servo motor determines the amount of abrasive to be separated according to the required grinding degree, and outputs torque to be transmitted to the arc plate through the linkage mechanism. The circumferentially evenly distributed arc plates rotate towards the outer arc surface. The main shaft transmits reverse torque to the inner cylinder. An included angle space is formed between the arc plate and the outer bottom cylinder. Through the reverse rotation of the outer bottom cylinder, a part of the abrasive is carried by the included angle space. The proportion of the carried abrasive is determined by the rotation of the arc plate, achieving the effect of adjusting the final grinding degree. The present invention designs a covering mechanism. After the second servo motor outputs positive torque, the materials held by the arc plates are thrown to the inner wall of the covering mechanism. The remaining abrasive and materials are mixed and ground under the drive of the arc plates. When the stirring and dividing mechanism rotates in the reverse direction, torque is transmitted to the anti-torsion mechanism through the connecting rod. The anti-torsion mechanism rotates and slides the top shell downward along the first slide rail through threaded connection with the internal thread hole. When the stirring and dividing mechanism rotates in the forward direction, due to the structure of the anti-torsion mechanism itself, the torque transmitted by the connecting rod is offset, and the anti-torsion mechanism no longer rotates, so that the covering mechanism will not move upward to cause the separated abrasive to leak out. The present invention designs an anti-torsion mechanism for cooperating with the covering mechanism. When the connecting rod transmits positive torque, in the top view perspective, the tooth ring rotates counterclockwise, and the arc tooth part meshes with the tooth surface of the tooth ring. Through the meshing of the inclined tooth surface, the rotation of the tooth ring is converted into the sliding of the arc tooth part along the inner groove. The arc tooth part is reset under the action of the compression spring, and the external threaded cylinder does not rotate. When the connecting rod transmits reverse torque, the arc tooth part abuts against the tooth back of the tooth ring, driving the external threaded cylinder to rotate through the arc tooth part and the inner groove. The present invention can separate the internal abrasive according to the required grinding degree, enabling the ground materials to reach different roughness and viscosity of slurry and liquid states, and detecting the grinding state, with high automation and greatly improving the grinding efficiency of the grinding machine.

According to the degree of grinding required, the first servo motor 2 outputs a reverse torque to separate a part of the abrasive according to the required grinding degree, and the pre-treated materials are input into the grinding mechanism 6 through the material conveying pipe 4. The first servo motor 2 outputs a forward torque, and the grinding mechanism 6 mixes the pre-wetted and pre-treated materials with part of the abrasive for rotary grinding. Through the shear collision between the materials and the abrasive, the materials finally present the required viscosity and roughness in a slurry state. After the detection mechanism 7 detects whether the roughness meets the requirements, the liquid pumping pump 5 pumps out the ground slurry.

[0035] As Figure 1 、 Figure 2 shown, the grinding mechanism 6 includes a housing 61, a main shaft 62, a stirring and distributing mechanism 63, a covering mechanism 64, and a filter screen 65.

[0036] According to the degree of grinding required, the first servo motor 2 outputs a reverse torque to the main shaft 62, the stirring and distributing mechanism 63 rotates in the reverse direction, grasps a part of the abrasive, the stirring and distributing mechanism 63 transmits the torque to the covering mechanism 64, the covering mechanism 64 descends to cover the upper part of the stirring and distributing mechanism 63 to separate the abrasive, and then the materials are injected into the housing 61. The first servo motor 2 outputs a forward torque to the main shaft 62, the stirring and distributing mechanism 63 rotates in the forward direction, mixes the pre-wetted and pre-treated materials with part of the abrasive for rotary grinding, and through the shear collision between the materials and the abrasive, the materials finally present the required viscosity and roughness in a slurry state. The liquid pumping pump 5 pumps out the ground slurry through the filter screen 65 to retain the abrasive.

[0037] As Figure 3 、 Figure 4As shown in the figure, the stirring and feeding mechanism 63 includes an outer bottom cylinder 631, an inner cylinder 632, arc plates 633, a linkage mechanism 634, and a second servo motor 635. The outer bottom cylinder 631 is fixedly connected to the inner cylinder 632, the material covering mechanism 64, and the filter screen 65. The inner cylinder 632 is drivingly connected to the main shaft 62. There are several groups of arc plates 633, and several groups of arc plates 633 are evenly distributed along the circumference of the outer bottom cylinder 631. Several groups of arc plates 633 are fixedly connected to the linkage mechanism 634, and several groups of arc plates 633 are rotatably connected to the outer bottom cylinder 631. The second servo motor 635 is fixedly connected to the outer bottom cylinder 631, and the output end of the second servo motor 635 is drivingly connected to the linkage mechanism 634.

[0038] It is set that the clockwise rotation towards the outer arc surface of the arc plate 633 is the positive direction, and the counterclockwise rotation is the negative direction. The second servo motor 635 determines the amount of abrasive to be separated according to the required grinding degree, and the output torque is transmitted to the arc plate 633 through the linkage mechanism 634. The circumferentially evenly distributed arc plates 633 rotate towards the outer arc surface. The main shaft 62 transmits a reverse torque to the inner cylinder 632. An included angle space is formed between the arc plate 633 and the outer bottom cylinder 631. By the reverse rotation of the outer bottom cylinder 631, a part of the abrasive is carried by the included angle space. The proportion of the carried abrasive is determined by the rotation angle of the arc plate 633. At the same time, the outer bottom cylinder 631 transmits torque to the material covering mechanism 64, and the material covering mechanism 64 slides downward along the first slide rail 611. After the second servo motor 635 outputs a positive torque, the material held by the arc plate 633 is thrown to the inner wall of the material covering mechanism 64, and the remaining abrasive and material are mixed and ground under the drive of the arc plate 633, achieving the effect of adjusting the final grinding degree.

[0039] As Figure 4 As shown in the figure, the linkage mechanism 634 includes a second transmission seat 6341, a transmission seat rod 6342, and a third transmission seat 6343.

There are several groups of transmission seat rods 6342 and third transmission seats 6343, and several groups of transmission seat rods 6342 and third transmission seats 6343 are evenly distributed along the circumference of the outer bottom cylinder 631. The second transmission seat 6341 is drivingly connected to the transmission seat rod 6342 by a belt, and the transmission seat rod 6342 is drivingly connected to the third transmission seat 6343 by a belt. Several groups of third transmission seats 6343 are fixedly connected to the arc plate 633.

[0040] The second servo motor 635 outputs torque to the second transmission seat 6341. The second transmission seat 6341 is drivingly connected to the circumferentially evenly distributed transmission seat rods 6342 by a belt. The belt drives the transmission seat rods 6342 to rotate on the outer bottom cylinder 631. The circumferentially evenly distributed transmission seat rods 6342 correspond to the third transmission seats 6343 one by one. The transmission seat rods 6342 drive the third transmission seats 6343 to rotate through the belt, transmit torque to the arc plate 633, and drive the arc plate 633 to rotate.

[0041] AsFigure 5 As shown in the figure, the cover material mechanism 64 includes a top shell 641, a connecting rod 642, and an anti-torsion mechanism 643. The connecting rod 642 is fixedly connected to the outer bottom cylinder 631, and the anti-torsion mechanism 643 is fixedly connected to the connecting rod 642.

The anti-torsion mechanism 643 is threadedly connected to the internal threaded hole 6411, and the convex block 6412 is slidably connected to the first slide rail 611.

[0042] When the stirring and distributing mechanism 63 rotates in the reverse direction, torque is transmitted to the anti-torsion mechanism 643 through the connecting rod 642. The anti-torsion mechanism 643 rotates and is threadedly connected to the internal threaded hole 6411, causing the top shell 641 to slide downward along the first slide rail 611. When the stirring and distributing mechanism 63 rotates in the forward direction, due to the structure of the anti-torsion mechanism 643 itself, the torque transmitted by the connecting rod 642 is offset, the anti-torsion mechanism 643 no longer rotates, and the cover material mechanism 64 does not move upward, allowing the separated abrasive to leak out.

[0044] When the connecting rod 642 transmits positive torque, in a top-down view, the tooth ring 6435 rotates counterclockwise. The arc tooth part 6434 is in meshing engagement with the tooth surface of the tooth ring 6435. Through the meshing of the helical tooth surfaces, the rotation of the tooth ring 6435 is converted into the sliding of the arc tooth part 6434 along the inner groove 6432. The arc tooth part 6434 is reset under the action of the compression spring 6433, and the external threaded cylinder 6431 does not rotate. When the connecting rod 642 transmits reverse torque, the arc tooth part 6434 abuts against the tooth back of the tooth ring 6435, and the external threaded cylinder 6431 is driven to rotate through the arc tooth part 6434 and the inner groove 6432.

[0046] The material that has completed grinding and pulping enters the housing 72 through the flow channel 71. The slurry materials with different grinding degrees drive the impeller 73 to rotate at different speeds. The impeller 73 transmits the torque to the tooth head rod 74. The tooth head rod 74 is in meshing engagement with the tooth surface of the resistance adjustment mechanism 75.

[0047] As Figure 7 shown, the resistance adjustment mechanism 75 includes a fixed seat 751, a bevel gear 752, a worm 753, a worm seat 754, a second slide rail 755, a metal electric sheet 756, and a rheostat 757. The fixed seat 751, the second slide rail 755, and the rheostat 757 are all fixedly connected to the housing 72. The bevel gear 752 is rotatably connected to the fixed seat 751. The bevel gear 752 is in meshing engagement with the tooth surface of the tooth head rod 74. The worm 753 is fixedly connected to the bevel gear 752.

The metal electric sheet 756 is fixedly connected to the worm seat 754. The metal electric sheet 756 is slidably connected to the rheostat 757.

[0048] The impeller 73 transmits the torque to the tooth head rod 74. The tooth head rod 74 is in meshing engagement with the tooth surface of the bevel gear 752, driving the bevel gear 752 to rotate. The bevel gear 752 transmits the torque to the worm 753.

The metal electric sheet 756 fixed on the worm seat 754 slides on the rheostat 757, causing the resistance of the rheostat 757 to change.

[0049] Working principle of the present invention: This grinding machine is used to grind and refine the pre-wetted and pre-treated materials. It is set that the clockwise rotation towards the outer arc surface of the arc plate 633 is the forward direction, and the counterclockwise rotation is the reverse direction. The second servo motor 635 determines the amount of abrasive to be separated according to the required grinding degree. The circumferentially evenly distributed arc plates 633 rotate towards the outer arc surface. The main shaft 62 transmits a reverse torque to the inner cylinder 632. An included angle space is formed between the arc plate 633 and the outer bottom cylinder 631. By the reverse rotation of the outer bottom cylinder 631, a part of the abrasive is carried in the included angle space. The proportion of the carried abrasive is determined by the rotation of the arc plate 633. The stirring and distributing mechanism 63 rotates in the reverse direction and grabs a part of the abrasive. The stirring and distributing mechanism 63 transmits torque to the covering mechanism 64. The covering mechanism 64 descends to cover the upper part of the stirring and distributing mechanism 63 to separate the abrasive. The material clamped by the arc plate 633 is thrown to the inner wall of the covering mechanism 64. When the stirring and distributing mechanism 63 rotates in the reverse direction, the anti-twisting mechanism 643 rotates. Through the threaded connection with the internal thread hole 6411, the top shell 641 slides downward along the first slide rail 611. When the stirring and distributing mechanism 63 rotates in the forward direction, due to the structure of the anti-twisting mechanism 643 itself, the torque transmitted by the connecting rod 642 is offset, the anti-twisting mechanism 643 no longer rotates, and the covering mechanism 64 does not move upward, so that the separated abrasive leaks out. The remaining abrasive and the material are mixed and ground under the drive of the arc plate 633 to achieve the effect of adjusting the final grinding degree. Then, the material is injected into the outer shell 61, and the pre-wetted and pre-treated material is mixed with part of the abrasive for rotary grinding. Through the shear collision between the material and the abrasive, the material finally presents the required viscosity, roughness, and slurry state. After the detection mechanism 7 detects whether the roughness meets the requirements, the liquid extraction pump 5 pumps out the ground slurry.
