Description

Technical Field

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

[0002] With the continuous development of modern industry, the demand for the refinement and processing of various materials is increasing day by day. Among them, tortoise shell materials are widely used in industries such as pharmaceuticals, chemicals, and food. During the processing of tortoise shell materials, the performance of the powder grinding equipment directly affects the production efficiency and the quality of the final product. During the processing of tortoise shell, the performance of the grinding equipment is crucial for the grinding efficiency and the quality of the final powder. The hardness of the tortoise shell is an important factor affecting the difficulty of its grinding. Tortoise shells with higher hardness usually have stronger compressive resistance and anti-breakage properties. Therefore, 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. While relatively softer tortoise shells are prone to cracking and breaking during the grinding process, so they can be more easily and quickly ground into powder with less energy consumption.

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

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. When the tortoise shell to be ground is relatively hard, by manually rotating the knob, it transmits torque through the bayonet and the clamping block, thereby driving the worm to rotate. The worm drives the worm gear to rotate. Since the worm gear is threadedly connected to the lead screw, when the worm gear rotates, it will drive the lead screw to slide downward along the direction of the hexagonal fixed column. The lead screw drives the spline shaft to move downward, and the spline shaft drives the grinding cover to move downward through the bracket. By moving the grinding cover downward, the distance between the discharge slits is reduced, so as to facilitate grinding the relatively hard tortoise shell into fine powder. With this device, the grinding gap can be flexibly adjusted according to the hardness of the tortoise shell, making the tortoise shell ground into powder more evenly and ensuring the quality of the tortoise shell powder; 2. When the lead screw moves downward, the friction component makes the pressing head press the worm more and more tightly, so that the friction between the rubber pad and the worm increases. When the user rotates the knob, there will be an increasingly large resistance. With this device, when the user adjusts the distance between the grinding chassis and the grinding cover, there will be an obvious tactile feedback, preventing the operator from rotating in the wrong direction, resulting in an increase in the particle size of the tortoise shell and insufficient grinding into powder.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and defined, terms such as "installation", "equipped with", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0019] Referring to Figures 1-11 , a high-efficiency tortoise shell powder grinding device, comprising: A workbench 1, and a plurality of legs are fixedly installed on the lower surface of the workbench 1; A powder grinding assembly, which is arranged above the workbench 1. The powder grinding assembly includes a grinding chassis 3 and a grinding cover 4. The grinding cover 4 is arranged above the grinding chassis 3. Grinding grooves are provided on the outer surfaces of the adjacent sides of the grinding chassis 3 and the grinding cover 4. A plurality of openings are provided on the upper surface of the support 5. A fixed cylinder 2 is fixedly installed on the upper surface of the workbench 1. The grinding chassis 3 is rotatably installed at the top of the fixed cylinder 2. A crushing and grinding cavity 402 is provided between the top of the grinding cover 4 and the grinding chassis 3. An outlet slit 401 is provided between the bottom ends of the grinding cover 4 and the grinding chassis 3. The spacing of the outlet slit 401 is smaller than that of the crushing and grinding cavity 402. A receiving tray 6 is fixedly installed on the outer surface of the grinding chassis 3. The receiving tray 6 is arranged below the crushing and grinding cavity 402; The user manually puts the tortoise shell into the inside of the crushing and grinding cavity 402 through the opening on the support 5. 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 conically arranged, the tortoise shell will slide towards the edge position of the grinding chassis 3. The grinding cover 4 and the grinding chassis 3 rotate in opposite directions, and the tortoise shell is scraped and ground through the grinding grooves on their surfaces, so that the tortoise shell is gradually ground into powder under the back-and-forth scraping and friction of the grinding grooves. The ground tortoise shell powder will slide down from the outlet slit 401 onto the receiving tray 6 for collection.

[0020] Adjusting assembly, used to adjust the distance between the grinding chassis 3 and the grinding cover 4. The adjusting assembly includes a spline shaft 7 slidably inserted into the upper surface of the workbench 1. The top end of the spline shaft 7 penetrates through the upper surface of the grinding chassis 3 and is fixedly installed with a bracket 5. A round opening is formed at the top end of the grinding cover 4, and the bracket 5 is fixedly installed with the inner wall of the round opening. A housing 12 is fixedly installed on the lower surface of the workbench 1. A hexagonal fixed column 13 is fixedly installed on the upper surface of the housing 12. A lead screw 14 is slidably installed on the outer surface of the hexagonal fixed column 13. The bottom end of the spline shaft 7 penetrates through the lower surface of the workbench 1 and is rotatably installed with the top end of the lead screw 14. A worm 16 is rotatably installed between the inner walls of two opposite sides of the housing 12. A worm gear 15 is rotatably installed on the lower surface of the workbench 1. The top end of the lead screw 14 penetrates through the upper surface of the worm gear 15 and is threadedly connected thereto. The worm 16 meshes with the worm gear 15. A support block 28 is fixedly installed on the lower surface of the workbench 1. One end of the worm 16 close to the support block 28 penetrates through the outer surface of the support block 28 and is fixedly installed with a slide rod 1601. A knob 17 is slidably installed on the outer surface of the slide rod 1601.

[0021] By manually rotating the knob 17, the torque is transmitted through the bayonet 1701 and the block 1602, thereby driving the worm 16 to rotate. The worm 16 drives the worm gear 15 to rotate. Since the worm gear 15 is threadedly connected to the lead screw 14, when the worm gear 15 rotates, it will drive the lead screw 14 to slide downward along the direction of the hexagonal fixed column 13. The lead screw 14 slides downward along the direction of the hexagonal fixed column 13, and the lead screw 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. By moving the grinding cover 4 downward, the spacing of the discharge slot 401 is reduced, so as to facilitate grinding the harder tortoise shell into fine powder. With this device, the grinding gap can be flexibly adjusted according to the hardness of the tortoise shell, making the tortoise shell ground into powder more evenly and ensuring the quality of the ground tortoise shell powder.

[0022] In this embodiment, a 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 below the workbench 1. The driving mechanism includes a second driven bevel gear 9 fixedly installed at the middle position of the lower surface of the grinding chassis 3. A first driven bevel gear 8 is rotatably installed on the upper surface of the workbench 1. The bottom end of the spline shaft 7 penetrates through the inside of the second driven bevel gear 9. The bottom end of the spline shaft 7 penetrates through the outer surface of the first driven bevel gear 8 and is slidably installed with its inner wall. A plurality of spline grooves 701 are equidistantly formed on the circumferential outer surface of the spline shaft 7. A plurality of splines are equidistantly arranged on the inner wall of the first driven bevel gear 8. 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 meshes with the second driven bevel gear 9 and the first driven bevel gear 8.

[0023] The driving motor 10 drives the driving bevel gear 11 to rotate. The driving bevel gear 11 meshes 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 second driven bevel gear 9 drives the grinding chassis 3 to rotate. 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. The tortoise shell is scraped and ground through the grinding grooves on their surfaces. With this device, the tortoise shell is gradually ground into pieces under the back-and-forth scraping friction of the grinding grooves, facilitating the grinding of the tortoise shell into powder.

[0024] In this embodiment, a plurality of bayonets 1701 are equidistantly formed on the end face of the knob 17 near one end of the worm 16. A plurality of blocks 1602 matching the bayonets 1701 are equidistantly arranged on the end face of the worm 16. The blocks 1602 are inserted into the interiors of the bayonets 1701 and are slidably installed on their inner walls. A counterbore 1703 is formed on the end face of the other end of the knob 17. A retaining piece 1603 is fixedly installed at the other end of the slide bar 1601 through the inner wall of the counterbore 1703. A sliding ring 1702 is arranged on the bottom wall of the counterbore 1703. The sliding ring 1702 is sleeved on the outer surface of the slide bar 1601 and is rotatably installed thereon. The sliding ring 1702 is slidably installed on the bottom wall of the counterbore 1703. A third spring 1604 is sleeved on the outer surface of the slide bar 1601. The third spring 1604 is arranged between the sliding ring 1702 and the retaining piece 1603.

[0025] When the tortoise shell to be ground is relatively hard, the knob 17 is manually rotated, so that torque is transmitted through the bayonets 1701 and the blocks 1602, thereby driving the worm 16 to rotate. The worm 16 drives the worm gear 15 to rotate. Since the worm gear 15 is threadedly connected to the lead screw 14, when the worm gear 15 rotates, the lead screw 14 will slide downward along the direction of the hexagonal fixed column 13. The lead screw 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. By moving the grinding cover 4 downward, the distance between the discharge slits 401 is reduced, thereby facilitating the grinding of the relatively hard tortoise shell into fine powder. With this device, the grinding gap can be flexibly adjusted according to the hardness of the tortoise shell, making the grinding of the tortoise shell into powder more uniform and ensuring the quality of the ground tortoise shell powder.

[0026] In this embodiment, a friction assembly is provided on the outer surface of the workbench 1. When the worm 16 rotates to adjust the distance between the grinding chassis 3 and the grinding cover 4, through the increase or decrease of the frictional resistance, the operator can feel whether the distance between the grinding chassis 3 and the grinding cover 4 increases or decreases. The friction assembly includes a mounting block 23 fixedly installed on the outer surface of the support block 28 close to the knob 17. A second compression cylinder 19 is fixedly installed on the outer surface of the workbench 1 close to the support block 28. A top rod 20 is slidably inserted into the upper surface of the mounting block 23. The top end of the top rod 20 is fixedly installed with a second piston plate 1901. The second piston plate 1901 is slidably installed on the inner wall of the second compression cylinder 19. The bottom end of the top rod 20 penetrates through the lower surface of the mounting block 23 and is fixedly installed with a pressing head 24. The bottom end of the pressing head 24 abuts against the outer surface of the worm 16. The bottom end of the pressing head 24 is provided with an arc surface matching the outer surface of the worm 16, and a rubber pad is arranged on the outer surface of the arc surface. A first compression cylinder 18 is fixedly installed on the upper surface of the housing 12. A 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 pressing column 1802. The top end of the pressing column 1802 penetrates through the top end of the first compression cylinder 18 and is fixedly connected to the lower surface of the lead screw 14. A plurality of exhaust holes 1804 are formed through the top end of the first compression cylinder 18. The outer surface of the first compression cylinder 18 close to the bottom end is fixedly connected with a hydraulic pipe 1803. The other end of the hydraulic pipe 1803 is fixedly connected to the top end of the second compression cylinder 19. The first compression cylinder 18 is internally connected to the second compression cylinder 19 through the hydraulic pipe 1803. The interiors of the first compression cylinder 18, the hydraulic pipe 1803, and the second compression cylinder 19 are filled with hydraulic oil.

[0027] When the lead screw 14 moves downward, the lead screw 14 will drive the first piston plate 1801 to move downward through the pressing 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 pressing head 24 to move downward through the top rod 20, so that the rubber pad on the bottom arc surface of the pressing head 24 abuts against the outer surface of the worm 16. As the distance of the discharge slit 401 gradually decreases, the pressing head 24 presses the worm 16 more and more tightly, so that the friction force between the rubber pad and the worm 16 increases. When the user rotates the knob 17, there will be an increasingly large resistance. Through this device, when the user adjusts the distance between the grinding chassis 3 and the grinding cover 4, there will be an obvious tactile feedback, preventing the operator from rotating in the wrong direction when turning, resulting in an increase in the particle size of the tortoise shell and insufficient grinding into powder.

[0028] The hard turtle shell has strong compressive and anti-fragmentation properties and is not easily crushed during the grinding process. Usually, more force and a longer time are required to grind it into powder. While the soft turtle shell is more likely to break under less pressure and is not prone to rebound, so it can be ground into powder more quickly. Generally, the hard turtle shell is not as likely to undergo cleavage as the soft turtle shell during the grinding process. Instead, it may experience fragmentation or excessive wear, resulting in uneven powder particles. The soft turtle shell is more likely to be evenly cleaved during grinding, producing finer powder. For the hard turtle shell, a higher energy input is required during the grinding process. Due to its greater hardness, the wear of the grinding equipment may also be exacerbated, increasing the burden on the equipment. The soft turtle shell, due to its easier breakage, requires less energy and has a relatively high grinding efficiency. By adjusting the gap, it is possible to avoid the device operating at high power all the time, saving the factory's electrical energy.

[0029] In this embodiment, a slippage component 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 slippage component, the bayonet 1701 on the knob 17 disengages from the block 1602. The slippage component includes a hexagonal sliding column 25 slidably inserted at the bottom end of the ejector rod 20. A tapered head 27 is fixedly installed at the bottom end of the hexagonal sliding column 25. An annular chamfer 1704 is provided on the end face of the knob 17 close to the tapered head 27. A conical surface matching the annular chamfer 1704 is provided on the outer surface of the tapered head 27. The conical surface abuts against the outer surface of the annular chamfer 1704. A second spring 26 is sleeved on the outer surface of the hexagonal sliding column 25. The top end of the second spring 26 is fixedly connected to the bottom end of the ejector rod 20, and the bottom end of the second spring 26 is fixedly connected to the top end of the tapered head 27. A limit ring 21 is fixedly installed on the outer surface of the ejector rod 20 close to the top end. A first spring 22 is sleeved on the outer surface of the ejector rod 20. The top end of the first spring 22 is fixedly connected to the lower surface of the limit ring 21, and the bottom end of the first spring 22 is fixedly connected to the upper surface of the mounting block 23.

[0030] By the downward movement of the ejector rod 20, it drives the tapered head 27 to move downward through the hexagonal sliding column 25 and the second spring 26. By the downward movement of the tapered head 27, the conical surface on its outer surface abuts 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 disengages from the block 1602, at this time, when the knob 17 is rotated further, it will no longer drive the worm 16 to rotate, and thus will no longer reduce the distance between the grinding chassis 3 and the grinding cover 4. Through this device, it is possible to 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 do not abut against each other and preventing damage to the grinding grooves on their surfaces.

[0031] When the knob 17 is turned 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 in the direction of 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 reversely turn the knob 17 to increase the distance between the grinding base 3 and the grinding cover 4, the user manually pushes the knob 17 to move it in the direction of the worm 16, thereby pushing the block 1602 back into the bayonet 1701. At this time, the user can reversely turn the knob 17 to increase the distance between the grinding base 3 and the grinding cover 4. 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 is slowly reset under the action of the second spring 26. The force of the second spring 26 is large enough to overcome the force of the third spring 1604, so that the knob 17 is disengaged from the worm 16.

[0032] In this embodiment, a certain gap is provided between the inner wall of the top rod 20 at the bottom and the hexagonal sliding column 25, so that air can flow freely when the hexagonal sliding column 25 slides on the inner wall.

[0033] The working principle of the present invention is that 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 bottom plate 3 and the grinding cover 4. Since the upper surface of the grinding bottom plate 3 is conical, the tortoise shell will slide to the edge of the grinding bottom plate 3. During grinding, the driving motor 10 drives the driving bevel gear 11 to rotate, and the driving bevel gear 11 meshes 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 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, and 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 through the grinding grooves on the surfaces of both. Through this device, the tortoise shell is ground into powder little by little under the back and forth scratching and friction of the grinding groove, so that the tortoise shell is ground into powder. The ground tortoise shell particles will move to the edge under the influence of the centrifugal force generated when the grinding base 3 rotates. 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. When the ground tortoise shell is hard, manually rotate the knob 17, so that it transmits torque through the bayonet 1701 and the clamping block 1602, thereby driving the worm 16 to rotate. The worm 16 drives the worm wheel 15 to rotate. Since the worm wheel 15 is threadedly connected to the lead screw 14, when the worm wheel 15 rotates, it will drive the lead screw 14 to slide downward along the direction of the hexagonal fixed column 13. The lead screw 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. By the downward movement of the grinding cover 4, the spacing of the discharge slit 401 is reduced, so as to facilitate grinding the hard tortoise shell into fine powder. With this device, the grinding gap can be flexibly adjusted according to the hardness of the tortoise shell, making the ground tortoise shell powder more uniform and ensuring the quality of the ground tortoise shell powder; When the lead screw 14 moves downward, the lead screw 14 will drive the first piston plate 1801 to move downward through the pressure column 1802. The first piston plate 1801 presses the hydraulic oil inside the first compression cylinder 18, and enters the inside 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 pressing head 24 to move downward through the ejector rod 20, so that the rubber pad on the bottom arc surface of the pressing head 24 abuts against the outer surface of the worm 16. As the spacing of the discharge slit 401 gradually decreases, the pressing head 24 presses the worm 16 more and more tightly, so that the friction between the rubber pad and the worm 16 increases. When the user rotates the knob 17, there will be an increasingly large resistance. With this device, when the user adjusts the spacing between the grinding chassis 3 and the grinding cover 4, there will be an obvious tactile feedback, preventing the operator from rotating in the wrong direction, resulting in an increase in the particle size of the tortoise shell and insufficient grinding into powder; Through the downward movement of the ejector rod 20, it drives the tapered head 27 to move downward through the hexagonal sliding column 25 and the second spring 26. Through the downward movement of the tapered head 27, the tapered surface on its outer surface abuts 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 clamping block 1602. When the bayonet 1701 disengages from the clamping block 1602, at this time, when the knob 17 is rotated continuously, it will no longer drive the worm 16 to rotate, and thus will no longer reduce the spacing between the grinding chassis 3 and the grinding cover 4. With this device, it is possible to avoid adjusting the spacing 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 do not abut against each other and avoiding damage to the grinding grooves on their surfaces; When the knob 17 is turned 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 in the direction of 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 reversely turn the knob 17 to increase the distance between the grinding base 3 and the grinding cover 4, the user manually pushes the knob 17 to move it in the direction of the worm 16, thereby pushing the block 1602 back into the bayonet 1701. At this time, the user can reversely turn the knob 17 to increase the distance between the grinding base 3 and the grinding cover 4. 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 is slowly reset under the action of the second spring 26. The force of the second spring 26 is large enough to overcome the force of the third spring 1604, so that the knob 17 is disengaged from the worm 16.
