A high-efficiency tortoise shell grinding equipment

Abstract

The present invention relates to the technical field of grinding equipment, and discloses a tortoise shell high-efficiency grinding equipment, comprising a workbench, a plurality of legs fixedly mounted on the lower surface of the workbench, and a grinding assembly, wherein the grinding assembly is arranged above the workbench, and the grinding assembly comprises a grinding chassis and a grinding cover. The present invention manually rotates a knob to transmit torque through a bayonet and a block, thereby causing the worm to drive the worm wheel to rotate. Since the worm wheel and the lead screw are threadedly connected, when the worm wheel rotates, the lead screw is driven to slide downward along the direction of the hexagonal fixed column, and the lead screw drives the spline shaft to move downward, and the spline shaft drives the grinding cover to move downward through a bracket. The downward movement of the grinding cover reduces the spacing of the discharge gap, thereby facilitating the grinding of harder tortoise shells into fine powder. The present device can flexibly adjust the grinding gap according to the hardness of the tortoise shell, so that the tortoise shell is ground into powder more evenly, thereby ensuring the quality of the tortoise shell powder.

Description

Technical Field

[0001] The present invention relates to the technical field of grinding equipment, in particular to a tortoise shell high-efficiency grinding equipment. Background Art

[0002] With the continuous development of modern industry, the demand for the refinement and processing of various materials is increasing. Among them, tortoise shell materials are widely used in the pharmaceutical, chemical, food and other industries. During the processing of tortoise shell materials, the performance of the grinding equipment directly affects the production efficiency and the quality of the final product. During the processing of tortoise shells, the performance of the grinding equipment is crucial to the grinding efficiency and the quality of the final powder. The hardness of tortoise shells is an important factor affecting their grinding difficulty. Tortoise shells with higher hardness usually have stronger resistance to compression and crushing, so they are not easily broken into powder during the grinding process, and often require higher force and longer grinding time to achieve the ideal crushing effect. The relatively soft tortoise shells are easy to crack and break during the grinding process, so they can be ground into powder more easily and quickly, and with less energy consumption.

[0003] Existing grinding equipment cannot flexibly adjust the grinding gap according to the hardness of the tortoise shell, which makes it difficult to control the grinding effect when processing tortoise shells with large differences in hardness, resulting in low grinding efficiency and uneven distribution of the grinding powder particle size, affecting the quality of the tortoise shell powder.

[0036] Reference Figures 1-11 , a tortoise shell high-efficiency grinding equipment, comprising:

[0037] A workbench 1, wherein a plurality of legs are fixedly mounted on the lower surface of the workbench 1;

[0038] A grinding assembly is arranged above the workbench 1, and the grinding assembly includes a grinding chassis 3 and a grinding cover 4. The grinding cover 4 is arranged above the grinding chassis 3, and the outer surfaces of the adjacent sides of the grinding chassis 3 and the grinding cover 4 are provided with grinding grooves. A plurality of openings are provided on the upper surface of the bracket 5. A fixed cylinder 2 is fixedly installed on the upper surface of the workbench 1, and the grinding chassis 3 is rotatably installed on the top of the fixed cylinder 2. A crushing and grinding chamber 402 is provided between the grinding cover 4 and the top of the grinding chassis 3, and a discharge gap 401 is provided between the grinding cover 4 and the bottom end of the grinding chassis 3. The spacing of the discharge gap 401 is smaller than that of the crushing and grinding chamber 402. A receiving tray 6 is fixedly installed on the outer surface of the grinding chassis 3, and the receiving tray 6 is provided below the crushing and grinding chamber 402;

[0039] The user manually puts the tortoise shell from the opening on the bracket 5 into the inside of the crushing and grinding chamber 402. At this time, the tortoise shell is located between the grinding chassis 3 and the grinding cover 4. Since the upper surface of the grinding chassis 3 is conical, the tortoise shell will slide to the edge of the grinding chassis 3. The grinding cover 4 and the grinding chassis 3 rotate in opposite directions relative to each other, and the grinding grooves on the surfaces of both sides will scratch and grind the tortoise shell, so that the tortoise shell is ground into powder little by little under the back and forth scratching and friction of the grinding grooves. The ground tortoise shell powder will slide from the discharge gap 401 to the receiving tray 6 for collection.

[0040] The adjustment component is used to adjust the distance between the grinding chassis 3 and the grinding cover 4. The adjustment component includes a spline shaft 7 that is slidably inserted into the upper surface of the workbench 1. The top of the spline shaft 7 passes through the upper surface of the grinding chassis 3 and is fixedly installed with a bracket 5. The top of the grinding cover 4 is provided with a circular opening. The bracket 5 is fixedly installed with the inner wall of the circular opening. The lower surface of the workbench 1 is fixedly installed with a shell 12. The upper surface of the shell 12 is fixedly installed with a hexagonal fixed column 13. The outer surface of the hexagonal fixed column 13 is slidably installed with a screw rod 14. The bottom end of the spline shaft 7 passes through The lower surface of the workbench 1 is rotatably mounted on the top end of the screw rod 14, and a worm 16 is rotatably mounted between the inner walls on opposite sides of the shell 12. The worm wheel 15 is rotatably mounted on the lower surface of the workbench 1, and the top end of the screw rod 14 passes through the upper surface of the worm wheel 15 and is threadedly connected to it. The worm 16 is meshed with the worm wheel 15. A support block 28 is fixedly mounted on the lower surface of the workbench 1, and a slide rod 1601 is fixedly mounted on the outer surface of the support block 28 at one end of the worm 16 close to the support block 28, and a knob 17 is slidably mounted on the outer surface of the slide rod 1601.

[0041] By manually turning the knob 17, the torque is transmitted through the bayonet 1701 and the block 1602, thereby driving the worm 16 to rotate, and the worm 16 drives the worm wheel 15 to rotate. Since the worm wheel 15 is threadedly connected to the screw rod 14, when the worm wheel 15 rotates, it will drive the screw rod 14 to slide downward along the direction of the hexagonal fixed column 13. The screw rod 14 slides downward along the direction of the hexagonal fixed column 13, and the screw rod 14 drives the spline shaft 7 to move downward. The spline shaft 7 drives the grinding cover 4 to move downward through the bracket 5. The grinding cover 4 moves downward, so that the spacing of the discharge gap 401 is reduced, which makes it easier to grind the harder tortoise shell into fine powder. Through this device, the grinding gap can be flexibly adjusted according to the hardness of the tortoise shell, so that the tortoise shell is ground into powder more evenly, ensuring the quality of the tortoise shell powder.

[0042] In this embodiment, the driving mechanism is used to drive the grinding chassis 3 and the grinding cover 4 to rotate in opposite directions. The driving mechanism is arranged under the workbench 1. The driving mechanism includes a second driven bevel gear 9 fixedly installed in the middle position of the lower surface of the grinding chassis 3. The first driven bevel gear 8 is rotatably installed on the upper surface of the workbench 1. The bottom end of the spline shaft 7 passes through the interior of the second driven bevel gear 9. The bottom end of the spline shaft 7 passes through the outer surface of the first driven bevel gear 8 and is slidably installed on its inner wall. The circumferential outer surface of the spline shaft 7 is equidistantly provided with a plurality of splines 701. The inner wall of the first driven bevel gear 8 is equidistantly provided with a plurality of splines, and the plurality of splines are respectively slidably installed with the inner walls of the plurality of spline grooves 701. A driving motor 10 is fixedly installed on the upper surface of the workbench 1. The output end of the driving motor 10 is fixedly installed with a driving bevel gear 11. The driving bevel gear 11 is meshed with the second driven bevel gear 9 and the first driven bevel gear 8.

[0043] The driving motor 10 drives the driving bevel gear 11 to rotate, and the driving bevel gear 11 engages with the first driven bevel gear 8 and the second driven bevel gear 9, thereby driving the first driven bevel gear 8 and the second driven bevel gear 9 to rotate in relative opposite directions. The grinding chassis 3 is driven to rotate through the second driven bevel gear 9, and the first driven bevel gear 8 transmits torque through the spline and the spline groove 701, thereby driving the spline shaft 7 to rotate. The spline shaft 7 drives the grinding cover 4 to rotate through the bracket 5. At this time, the grinding cover 4 and the grinding chassis 3 rotate in relative opposite directions, and the tortoise shell is scratched and ground through the grinding grooves on the surfaces of both. Through this device, the tortoise shell is ground into powder bit by bit under the back and forth friction of the grinding groove, so that the tortoise shell is ground into powder.

[0044] In this embodiment, the end surface of the knob 17 near one end of the worm 16 is equidistantly provided with a plurality of bayonet holes 1701, and the end surface of the worm 16 is equidistantly provided with a plurality of blocking blocks 1602 matching the bayonet holes 1701. The blocking blocks 1602 are inserted into the interior of the bayonet holes 1701 and slidably mounted on the inner wall thereof. A countersunk hole 1703 is provided on the end surface of the other end of the knob 17. A blocking piece 1603 is fixedly mounted on the other end of the slide rod 1601 through the inner wall of the countersunk hole 1703. A slip ring 1702 is provided on the bottom wall of the countersunk hole 1703. The slip ring 1702 is sleeved on the outer surface of the slide rod 1601 and rotatably mounted thereon. The slip ring 1702 is slidably mounted on the bottom wall of the countersunk hole 1703. A third spring 1604 is sleeved on the outer surface of the slide rod 1601. The third spring 1604 is arranged between the slip ring 1702 and the blocking piece 1603.

[0045] When the tortoise shell to be ground is harder, the knob 17 is manually turned to transmit torque through the bayonet 1701 and the block 1602, thereby driving the worm 16 to rotate, and the worm 16 drives the worm wheel 15 to rotate. Since the worm wheel 15 is threadedly connected to the screw rod 14, when the worm wheel 15 rotates, it will drive the screw rod 14 to slide downward along the direction of the hexagonal fixed column 13, and the screw rod 14 drives the spline shaft 7 to move downward. The spline shaft 7 drives the grinding cover 4 to move downward through the bracket 5. The downward movement of the grinding cover 4 reduces the spacing of the discharge gap 401, thereby facilitating the grinding of the harder tortoise shell into fine powder. Through this device, the grinding gap can be flexibly adjusted according to the hardness of the tortoise shell, so that the tortoise shell is ground into powder more evenly, ensuring the quality of the tortoise shell powder.

[0046] In this embodiment, a friction assembly is provided on the outer surface of the workbench 1. When the worm 16 is rotated to adjust the distance between the grinding chassis 3 and the grinding cover 4, the operator can feel the increase or decrease of the distance between the grinding chassis 3 and the grinding cover 4 through the increase or decrease of the friction resistance. The friction assembly includes a mounting block 23 fixedly mounted on the outer surface of the support block 28 near the knob 17. A second compression cylinder 19 is fixedly mounted on the outer surface of the workbench 1 near the support block 28. A push rod 20 is slidably inserted into the upper surface of the mounting block 23. A second piston plate 1901 is fixedly mounted on the top of the push rod 20. The second piston plate 1901 is slidably mounted on the inner wall of the second compression cylinder 19. The bottom end of the push rod 20 passes through the lower surface of the mounting block 23 and is fixedly mounted with a pressure head 24. The bottom end of the pressure head 24 is against the outer surface of the worm 16, and the bottom end of the pressure head 24 is provided with a The arc surface matches the outer surface of the worm 16, and the outer surface of the arc surface is provided with a rubber pad. The first compression cylinder 18 is fixedly installed on the upper surface of the shell 12, and the first piston plate 1801 is slidably installed on the inner wall of the first compression cylinder 18. The upper surface of the first piston plate 1801 is fixedly installed with a pressure column 1802, and the top of the pressure column 1802 passes through the top of the first compression cylinder 18 and is fixedly connected to the lower surface of the screw rod 14. A plurality of exhaust holes 1804 are opened through the top of the first compression cylinder 18. The outer surface of the first compression cylinder 18 near the bottom is fixedly connected with a hydraulic pipe 1803, and the other end of the hydraulic pipe 1803 is fixedly connected to the top of the second compression cylinder 19. The first compression cylinder 18 is connected to the interior of the second compression cylinder 19 through the hydraulic pipe 1803, and the interiors of the first compression cylinder 18, the hydraulic pipe 1803 and the second compression cylinder 19 are filled with hydraulic oil.

[0047] When the screw rod 14 moves downward, the screw rod 14 will drive the first piston plate 1801 downward through the pressure column 1802. The first piston plate 1801 presses the hydraulic oil inside the first compression cylinder 18 and enters the interior of the second compression cylinder 19 through the hydraulic pipe 1803, so that the hydraulic oil inside it presses the second piston plate 1901 to move downward. The second piston plate 1901 drives the pressure head 24 downward through the push rod 20, so that the rubber pad on the arc surface at the bottom end of the pressure head 24 is against the outer surface of the worm 16. As the spacing of the discharge gap 401 gradually decreases, the pressure head 24 presses the worm 16 more and more, thereby increasing the friction between the rubber pad and the worm 16, so that when the user turns the knob 17 again, there will be a gradually increasing resistance. Through this device, the user can have obvious tactile feedback when adjusting the spacing between the grinding chassis 3 and the grinding cover 4, preventing the operator from turning in the wrong direction, resulting in an increase in the particle size of the tortoise shell and insufficient grinding into powder.

[0048] Hard tortoise shells are more resistant to compression and crushing, making them less likely to break during the grinding process. Grinding them into powder usually requires more force and a longer time. Soft tortoise shells, on the other hand, break more easily under less pressure and are less likely to rebound, allowing them to be ground into powder more quickly. Hard tortoise shells generally don't break as easily as soft ones during the grinding process. Instead, they may fragment or become excessively worn, resulting in uneven powder particles. Soft tortoise shells, on the other hand, break more evenly during grinding, producing a finer powder. The grinding process for hard tortoise shells requires a higher energy input. Due to their greater hardness, wear on the grinding equipment may also increase, increasing the burden on the equipment. Soft tortoise shells, on the other hand, are easier to break, require less energy, and have relatively higher grinding efficiency. Adjustable gaps can prevent the device from operating at high power all the time, saving the factory's electrical energy.

[0049] In this embodiment, a slip assembly is provided between the knob 17 and the worm 16. After the distance between the grinding chassis 3 and the grinding cover 4 is adjusted to a certain distance through the slip assembly, the bayonet 1701 on the knob 17 is disengaged from the block 1602. The slip assembly includes a hexagonal slide column 25 slidably inserted at the bottom end of the top rod 20. The bottom end of the hexagonal slide column 25 is fixedly mounted with a conical head 27. The end surface of the knob 17 close to the conical head 27 is provided with an annular chamfer 1704, and the outer surface of the conical head 27 is provided with a conical surface matching the annular chamfer 1704. The conical surface abuts against the outer surface of the annular chamfer 1704. The outer surface of the hexagonal sliding column 25 is sleeved with a second spring 26. The top end of the second spring 26 is fixedly connected to the bottom end of the push rod 20. The bottom end of the second spring 26 is fixedly connected to the top of the conical head 27. A limiting ring 21 is fixedly installed on the outer surface of the push rod 20 near the top. The outer surface of the push rod 20 is sleeved with a first spring 22. The top end of the first spring 22 is fixedly connected to the lower surface of the limiting ring 21, and the bottom end of the first spring 22 is fixedly connected to the upper surface of the mounting block 23.

[0050] By moving the push rod 20 downward, the conical head 27 is driven downward through the hexagonal slide column 25 and the second spring 26. The downward movement of the conical head 27 causes the conical surface of its outer surface to abut against the annular chamfer 1704, thereby driving the knob 17 to move away from the worm 16, and the bayonet 1701 on the knob 17 will slowly disengage from the block 1602. When the bayonet 1701 is disengaged from the block 1602, at this time, when the knob 17 is continued to be turned, the worm 16 will no longer be driven to rotate, thereby no longer reducing the distance between the grinding chassis 3 and the grinding cover 4. This device can avoid adjusting the distance between the grinding chassis 3 and the grinding cover 4 too small, thereby ensuring that the outer surfaces of the grinding chassis 3 and the grinding cover 4 will not abut against each other, avoiding damage to the grinding grooves on the surfaces of both.

[0051] When rotating the knob 17 to reduce the distance between the grinding base 3 and the grinding cover 4, it should be noted that the user does not need to manually apply additional force to push the knob 17 toward the worm 16. After the bayonet 1701 of the knob 17 is disengaged from the block 1602 of the worm 16, when it is necessary to rotate the knob 17 in the opposite direction to increase the distance between the grinding base 3 and the grinding cover 4, the user manually pushes the knob 17 to move it toward the worm 16, thereby pushing the block 1602 back into the bayonet 1701. At this time, the user can increase the distance between the grinding base 3 and the grinding cover 4 by rotating the knob 17 in the opposite direction.

[0052] When the knob 17 is pushed, the conical head 27 is resisted by the conical surface and the annular chamfer 1704, thereby moving upward until it slowly returns to its original position under the action of the second spring 26. The force of the second spring 26 is relatively large and can overcome the force of the third spring 1604, causing the knob 17 to disengage from the worm 16.

[0053] In this embodiment, a certain gap is provided between the inner wall of the bottom end of the top rod 20 and the hexagonal sliding column 25, so that air can flow freely when the hexagonal sliding column 25 slides on the inner wall.

[0054] The working principle of the present invention is that the user manually puts the tortoise shell into the grinding chamber 402 through the opening on the bracket 5. At this time, the tortoise shell is located between the grinding base 3 and the grinding cover 4. Since the upper surface of the grinding base 3 is conical, the tortoise shell will slide toward the edge of the grinding base 3.

[0055] During grinding, the driving motor 10 drives the driving bevel gear 11 to rotate, and the driving bevel gear 11 is engaged with the first driven bevel gear 8 and the second driven bevel gear 9, thereby driving the first driven bevel gear 8 and the second driven bevel gear 9 to rotate in opposite directions. The grinding chassis 3 is driven to rotate by the second driven bevel gear 9, and the first driven bevel gear 8 transmits torque through the spline and the spline groove 701, thereby driving the spline shaft 7 to rotate. The spline shaft 7 drives the grinding cover 4 to rotate through the bracket 5. At this time, the grinding cover 4 and the grinding chassis 3 rotate in opposite directions relative to each other, and the tortoise shell is scratched and ground by the grinding grooves on the surfaces of both. Through this device, the tortoise shell is ground into powder bit by bit under the back and forth scratching and friction of the grinding groove, so that the tortoise shell is ground into powder.

[0056] The ground tortoise shell particles will move toward the edge under the influence of the centrifugal force generated by the rotation of the grinding base 3. When they move to the discharge slot 401, since the spacing of the discharge slot 401 is smaller than that of the grinding chamber 402, the ground tortoise shells can be further ground into powder to achieve the desired powder form.

[0057] When the tortoise shell to be ground is harder, the knob 17 is manually turned to transmit torque through the bayonet 1701 and the block 1602, thereby driving the worm 16 to rotate, and the worm 16 drives the worm wheel 15 to rotate. Since the worm wheel 15 is threadedly connected to the screw rod 14, when the worm wheel 15 rotates, it drives the screw rod 14 to slide downward along the direction of the hexagonal fixed column 13, and the screw rod 14 drives the spline shaft 7 to move downward. The spline shaft 7 drives the grinding cover 4 to move downward through the bracket 5. The downward movement of the grinding cover 4 reduces the spacing of the discharge gap 401, thereby facilitating the grinding of harder tortoise shells into fine powder. Through this device, the grinding gap can be flexibly adjusted according to the hardness of the tortoise shell, so that the tortoise shell is ground into powder more evenly, ensuring the quality of the tortoise shell powder.

[0058] When the screw rod 14 moves downward, the screw rod 14 will drive the first piston plate 1801 downward through the pressure column 1802. The first piston plate 1801 presses the hydraulic oil inside the first compression cylinder 18, and enters the interior of the second compression cylinder 19 through the hydraulic pipe 1803, so that the hydraulic oil inside it presses the second piston plate 1901 to move downward. The second piston plate 1901 drives the pressure head 24 downward through the push rod 20, so that the rubber pad on the arc surface at the bottom end of the pressure head 24 abuts against the outer surface of the worm 16. As the distance between the discharge gap 401 gradually decreases, the pressure head 24 presses the worm 16 more and more, thereby increasing the friction between the rubber pad and the worm 16, so that when the user turns the knob 17 again, there will be a gradually increasing resistance. Through this device, the user can have obvious tactile feedback when adjusting the distance between the grinding chassis 3 and the grinding cover 4, to prevent the operator from turning in the wrong direction, resulting in an increase in the particle size of the tortoise shell and insufficient grinding into powder.

[0059] By moving the push rod 20 downward, the conical head 27 is driven downward via the hexagonal slide column 25 and the second spring 26. The downward movement of the conical head 27 causes the conical surface of its outer surface to abut against the annular chamfer 1704, thereby driving the knob 17 to move away from the worm 16. The bayonet 1701 on the knob 17 will slowly disengage from the block 1602. When the bayonet 1701 is disengaged from the block 1602, the worm 16 will no longer be driven to rotate when the knob 17 is continued to be turned, thereby no longer reducing the gap between the grinding base 3 and the grinding cover 4. This device can avoid adjusting the gap between the grinding base 3 and the grinding cover 4 too small, thereby ensuring that the outer surfaces of the grinding base 3 and the grinding cover 4 will not abut against each other, thereby avoiding damaging the grinding grooves on the surfaces of both.

[0060] When rotating the knob 17 to reduce the distance between the grinding base 3 and the grinding cover 4, it should be noted that the user does not need to manually apply additional force to push the knob 17 toward the worm 16. After the bayonet 1701 of the knob 17 is disengaged from the block 1602 of the worm 16, when it is necessary to rotate the knob 17 in the opposite direction to increase the distance between the grinding base 3 and the grinding cover 4, the user manually pushes the knob 17 to move it toward the worm 16, thereby pushing the block 1602 back into the bayonet 1701. At this time, the user can increase the distance between the grinding base 3 and the grinding cover 4 by rotating the knob 17 in the opposite direction.

[0061] When the knob 17 is pushed, the conical head 27 is resisted by the conical surface and the annular chamfer 1704, thereby moving upward until it slowly returns to its original position under the action of the second spring 26. The force of the second spring 26 is relatively large and can overcome the force of the third spring 1604, causing the knob 17 to disengage from the worm 16.
