Description

Technical Field

[0001] The invention relates to the technical field of artificial bone powder preparation, in particular to an artificial bone powder preparation device with a particle size screening function. Background Art

[0002] Artificial bone powder has excellent bone regeneration and repair capabilities, and plays a pivotal role in the fields of oral implant surgery. With its unique properties and wide application prospects, it has become an indispensable part of modern stomatology. By closely adhering to native bone, artificial bone powder can stimulate the activity of bone cells, promote the formation of new bone, and thus restore the supporting structure of teeth.

[0003] The preparation of artificial bone powder requires grinding. Existing equipment will produce bone powder particles of different particle sizes during grinding. Bone powder particles can be used in different parts according to their particle sizes. However, a large amount of fine particles of powder will be produced during grinding. These powders will cause blockage of medical equipment and cannot be used in bone grafting surgery. Not only will the bone powder raw materials be wasted, but they also need to be cleaned up, which increases the preparation steps of artificial bone powder and reduces production efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide an artificial bone powder preparation device with a particle size screening function to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an artificial bone powder preparation device with a particle size screening function, comprising a support platform, a crushing preparation device is installed on the support platform, a grinding crusher is installed in the crushing preparation device, a positioning rod is installed at the top of the support platform, the bottom end of the positioning rod is movably connected to the top of the grinding crusher, an electric telescopic rod is installed at the bottom end of the support platform, and the output shaft of the electric telescopic rod is connected to the crushing preparation device; the crushing preparation device comprises a preparation shell and a bottom bracket, a grinding disc is installed in the preparation shell, a first motor is installed in the bottom bracket, the bottom bracket is slidably connected to the preparation shell, a first rotating rod is installed on the output shaft of the first motor, and the grinding crusher is eccentrically installed on the first rotating rod; the first rotating rod comprises an upper rotating rod and a lower rotating rod, the grinding crusher is eccentrically installed on the upper rotating rod, a cross connecting column is installed at the top of the lower rotating rod, a cross connecting groove matching the shape of the cross connecting column is provided at the bottom end of the upper rotating rod, the cross connecting column is embedded in the cross connecting groove, the bottom end of the lower rotating rod is connected to the output shaft of the first motor, and the lower rotating rod is connected to the upper rotating rod through the cross connecting column.

[0006] A control system is arranged inside the support platform, and the control system is used to control the entire artificial bone powder preparation device.

[0007] When the bone meal content is detected, the control system turns on the electric telescopic rod, and the output shaft of the electric telescopic rod drives the bottom support to descend, and the bottom material box and the first motor descend with the bottom support. The output shaft of the first motor drives the lower rotating rod to separate from the upper rotating rod. After the bottom support is completely dropped, the staff removes the bottom material box, takes out the dust and unqualified aggregate inside, and cleans the bottom material box. After that, the bottom material box is reset, and the control system drives the bottom support to rise through the electric telescopic rod, and the lower rotating rod is connected to the upper rotating rod again through the cross connecting column. After that, the control system turns on the electric valve on the bottom screening box and starts the drive device. The drive device drives the screening disc to vibrate, and the vibration causes the qualified aggregate to fall quickly from the electric valve and fall into the fine material compartment. This cycle is repeated to achieve layer-by-layer material unloading.

[0008] The crushing preparation device also includes a number of vibration detectors, which are installed in the preparation shell. A screening box is movably connected to the vibration detector. The screening box is slidably connected to the lower rotating rod. A number of dust suction plates are installed in the preparation shell. A bottom material box is provided on the bottom support. The bottom material box is rotatably connected to the lower rotating rod. A driving device is installed in the preparation shell. A number of vibration rings are rotatably installed on the dust suction plate. The driving device is rotatably connected to the vibration ring. A number of electromagnetic heads are provided at the bottom end of the vibration ring. A screen is provided at the bottom end of the screening box. An electric valve is provided on the screen. A number of screening connectors are installed on the screening box. The screening box is movably connected to the vibration detector through the screening connector. The screen apertures on the several screening boxes decrease one by one.

[0009] The crushing and preparation device also includes a rotating compression disk, which is eccentrically and rotatably installed in the grinding disk, and is rotatably connected to the driving device. The rotating compression disk is provided with a plurality of sliding grooves, and compression slides are slidably installed in the sliding grooves; the grinding disk is provided with a conical slope, and the conical slope is provided with a plurality of grinding heads whose sizes decrease from top to bottom. The grinding disk is provided with a cavity, and the rotating compression disk is eccentrically and rotatably installed in the cavity. A plurality of compression chambers are formed between the rotating compression disk, the grinding disk and the compression slides, and an air outlet pipe and an air inlet pipe are respectively provided on the grinding disk. The air inlet pipe is connected with the inside of the dust suction plate through a multi-way pipe, and the air outlet pipe and the air inlet pipe are connected with the cavity.

[0010] The driving device includes a second motor, which is installed at the bottom end of the preparation shell. The output shaft of the second motor passes through the preparation shell and is equipped with a second rotating rod. The top end of the second rotating rod is rotatably connected to the preparation shell. A plurality of transmission wheels are installed on the second rotating rod, and the transmission wheels are rotatably connected to the inside of the vibration ring and the rotating compression disk through transmission belts.

[0011] The control system starts the second motor, and the second motor drives the second rotating rod to rotate. The second rotating rod drives the rotating compression disk to rotate eccentrically through the transmission wheel and the transmission belt. The rotating compression disk drives the compression slide to rotate. Under the action of centrifugal force, the compression slide slides out of the sliding groove until it contacts the inner wall of the cavity of the grinding disk. The volume of the compression chamber between the two compression slides decreases with rotation. When the compression chamber rotates to the air outlet pipe, the compressed air inside is quickly discharged from the air outlet pipe. Thereafter, when the compression chamber rotates to the air inlet pipe, the volume of the compression chamber increases, and a negative pressure is formed inside, so that the external air is sucked in from the air inlet pipe. Since the air inlet pipe is connected to the inside of the dust suction plate through the multi-way pipe, the air inside the dust suction plate is sucked away to generate negative pressure, so that the dust suction port generates suction. When the ground bone powder falls to the first-layer screening box, the powder generated during the crushing and grinding process will be sucked away by the dust suction plate to prevent dust from adhering to the surface of qualified bone powder particles and reducing the quality of the finished product. The sucked dust falls into the dust cabin of the bottom material box from the discharge port at the bottom of the dust suction plate;

[0012] The vibration detector includes a detection bracket, which is installed in a preparation shell. A detection rotating rod is rotatably installed on the detection bracket, a movable connecting head is installed at one end of the detection rotating rod, an adsorption head is installed on the detection rotating rod, a measuring rod is installed on the detection rotating rod, a vibration spring is installed between the detection rotating rod and the detection bracket, a diaphragm is installed in the detection bracket, piezoelectric elements are installed between the diaphragms, and the movable connecting head is movably connected to the screening connecting head.

[0013] When the driving device drives the rotating compression disk to rotate, the vibration ring is driven to rotate synchronously through the transmission wheel and the transmission belt. The control system energizes the electromagnetic head on the vibration ring, and the vibration ring drives the electromagnetic head to rotate. When the electromagnetic head rotates above the adsorption head, it adsorbs the adsorption head, and the adsorption head drives the detection rotating rod upward to rotate around the detection bracket. The vibration spring at the bottom of the detection rotating rod is compressed, and the vibration spring at the top of the detection rotating rod is stretched, and the screening box connected to the detection rotating rod slides upward along the lower rotating rod. After that, after the electromagnetic head turns away from the adsorption head, the detection rotating rod rotates to the opposite angle under the action of the vibration spring, and then reciprocates under the action of inertia, driving the screening box to vibrate up and down. After that, the electric The magnetic head rotates again to the top of the adsorption head to adsorb the adsorption head, and the cycle is repeated to make the screening box vibrate continuously. During the vibration, the bone powder jumps up and down, and the mixed powder in the bone powder is lifted up and further sucked away by the dust suction plate. The bone powder with large particle size remains in the first layer of the screening box, and the bone powder with smaller particle size falls into the next layer of the screening box under the action of its own gravity as it vibrates. During the falling process, the powder in the bone powder is sucked away by the dust suction plate again. By controlling the size of the magnetic force of the electromagnetic head, the deflection angle of the detection rod can be controlled, thereby realizing the adjustment of the vibration amplitude of the screening box. This cycle is repeated until the bone powder is completely screened. Finally, the unqualified bone powder with too small particle size falls into the fine material cabin at the bottom.

[0014] When the screening is completed, the finished bone powder in the screening box will sink due to gravity, and the detection rod will rotate downward under the combined action of the screening box's own gravity and the bone powder's gravity. Since the detection rod rotates on the detection bracket in the form of a lever, the gravity of the bone powder is amplified under the action of the lever, and the other end of the detection rod drives the measuring rod to push the diaphragm upward. The piezoelectric elements between the diaphragms are compressed to generate current, and the generated current is transmitted to the control system through the wire. The control system analyzes the increase in the electrical signal by comparing it with the initial value of the electrical signal, thereby calculating the content of bone powder of each particle size, and judges the quality of the preparation by analyzing the content. When the quality is reduced, a maintenance signal is sent to the staff.

[0015] The grinding crusher includes a crushing cone head, a connecting round head is installed on the top of the crushing cone head, the connecting round head is movably connected to the positioning rod, a grinding cone head is installed on the bottom of the crushing cone head, and a plurality of grinding grooves with decreasing sizes from top to bottom are arranged on the grinding cone head. A crushing chamber is formed between the crushing cone head and the preparation shell, and a grinding chamber is formed between the grinding cone head and the conical slope of the grinding disc.

[0016] The raw material is poured in from the top of the preparation shell. After the raw material enters the crushing chamber, the control system starts the first motor, and the output shaft of the first motor drives the first rotating rod to rotate, and the first rotating rod drives the grinding crusher to rotate. Since the grinding crusher is eccentrically installed on the first rotating rod, the side of the crushing cone head that is smaller than the preparation shell will perform preliminary extrusion and crushing on the raw material when the crushing cone head rotates, and the broken raw material falls evenly from the gap between the crushing cone head and the preparation shell to the grinding chamber; the grinding groove on the grinding cone head cooperates with the grinding head on the grinding disc to grind the raw material fragments. Since the grinding head and the grinding groove are arranged in a decreasing size manner, the raw material fragments are gradually ground into bone powder, and the bone powder with a standard particle size falls from the gap between the grinding cone head and the bottom of the grinding disc to the first screening box, and the bone powder with a large particle size cannot pass through the gap between the grinding cone head and the bottom of the grinding disc and continues to be ground.

[0017] The dust suction plate is provided with several dust suction ports. The dust suction plate is a hollow structure. A dust suction pipe is provided on the dust suction plate. The dust suction pipe is connected with the inside of the dust suction plate. A feeding port is provided at the bottom of the dust suction plate. The air inlet pipe is connected with several dust suction pipes through a multi-way pipe. A filter is provided between the dust suction pipe and the dust suction plate.

[0018] A dust cabin is provided on the bottom material box, and a fine material cabin is provided on the bottom material box. The position of the dust cabin corresponds to the discharge port of the dust suction plate, and the position of the fine material cabin corresponds to the screen.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The driving device drives the rotating compression disc and the compression slide to rotate, and cooperates with the compression chamber inside the grinding disc to make the dust suction plate generate negative pressure, so as to achieve the effect of sucking out the powder, preventing the dust from adhering to the surface of qualified bone powder particles and reducing the quality of the finished product. At the same time, the sucked dust falls from the discharge port at the bottom of the dust suction plate into the dust cabin of the bottom material box, realizing the effect of automatic powder collection.

[0021] 2. Use the driving device to synchronously drive the vibration ring to rotate, and use the clutch of the electromagnetic head and the adsorption head to make the detection rod drive the screening box to vibrate with the cooperation of the vibration spring, and use the vibration to make the bone powder jump up and down, which not only makes the mixed powder in the bone powder rise and be further sucked away by the dust collection plate, but also allows the bone powder with smaller particle size to fall into the next layer of screening box under the action of its own gravity with the vibration, so as to achieve the purpose of multi-stage screening and purification; finally, use the fine material cabin to collect the unqualified bone powder.

[0022] 3. When in a static state, the detection rod drives the measuring rod to deflect and squeeze the piezoelectric element under the combined action of the gravity of the screening box itself and the gravity of the bone powder. The piezoelectric element transmits the electrical signal to the control system. The control system analyzes the increase in the electrical signal by comparing it with the initial value of the electrical signal, thereby calculating the content of bone powder of each particle size. The quality of the preparation is judged by analyzing the content. When the quality is reduced, a maintenance signal is sent to the staff. At the same time, the weight of the bone powder is amplified through the lever principle, which is convenient for generating a more obvious electrical signal, making the detection of the bone powder content more accurate.

[0023] 4. Use a grinding and crushing machine to perform crushing and grinding operations at the same time. First, crush the raw materials into uniform blocks, and then grind them into bone powder that meets the particle size requirements through fine grinding, so as to achieve multi-level finishing of the raw materials, make the bone powder particles more uniform, and avoid excessive waste. The grinding cone head and the grinding disc are designed in a conical shape, and the grinding cone head is installed eccentrically, so that large-sized bone powder cannot pass through the gap between the grinding cone head and the bottom of the grinding disc, and will not fall until it is ground to a size that meets the standard, avoiding the situation where the bone powder particle size is too large.

[0024] 5. Use the electric telescopic rod to drive the bottom material box on the bottom support to descend, and complete the automatic unloading of powder and unqualified bone meal. After that, use the driving device to drive the screening box to vibrate, so that the qualified aggregate quickly falls from the electric valve, and the qualified bone meal is discharged in a graded manner.

[0045] The vibration detector 46 includes a detection bracket 461, which is installed in the preparation shell 41. A detection rotating rod 462 is rotatably installed on the detection bracket 461, a movable connecting head 468 is installed at one end of the detection rotating rod 462, an adsorption head 463 is installed on the detection rotating rod 462, a measuring rod 466 is installed on the detection rotating rod 462, a vibration spring 465 is installed between the detection rotating rod 462 and the detection bracket 461, a diaphragm 464 is installed in the detection bracket 461, a piezoelectric element 467 is installed between the diaphragms 464, and the movable connecting head 468 is movably connected to the screening connecting head 492.

[0046] The dust suction plate 45 is provided with several dust suction ports 451. The dust suction plate 45 is a hollow structure. A dust suction pipe 452 is provided on the dust suction plate 45. The dust suction pipe 452 is connected to the inside of the dust suction plate 45. A discharge port is provided at the bottom end of the dust suction plate 45. The air inlet pipe 472 is connected to the several dust suction pipes 452 through a multi-way pipe. A filter is provided between the dust suction pipe 452 and the dust suction plate 45.

[0047] A dust cabin 4101 is provided on the bottom material box 410 , and a fine material cabin 4102 is provided on the bottom material box 410 . The position of the dust cabin 4101 corresponds to the discharge port of the dust suction plate 45 , and the position of the fine material cabin 4102 corresponds to the screen 491 .

[0048] The working principle of the present invention is as follows: the raw material is poured from the top of the preparation shell 41. After the raw material enters the crushing chamber 54, the control system starts the first motor 44, the output shaft of the first motor 44 drives the first rotating rod 48 to rotate, and the first rotating rod 48 drives the grinding crusher 5 to rotate. Since the grinding crusher 5 is eccentrically installed on the first rotating rod 48, the side of the crushing cone head 52 that is closer to the preparation shell 41 when rotating will initially squeeze and crush the raw material, and the raw material that is broken into pieces will be evenly distributed from the crushing cone head 52 and the preparation shell 41. The raw material fragments are ground into bone powder gradually, and the bone powder with the standard particle size falls from the gap between the grinding cone head 51 and the bottom end of the grinding disc 47 to the first layer screening box 49, and the bone powder with large particle size cannot pass through the gap between the grinding cone head 51 and the bottom end of the grinding disc 47 and continues to be ground.

[0049] The control system turns on the second motor 431, and the second motor 431 drives the second rotating rod 432 to rotate. The second rotating rod 432 drives the rotating compression disk 412 to rotate eccentrically through the transmission wheel 433 and the transmission belt 434. The rotating compression disk 412 drives the compression slide 413 to rotate. Under the action of centrifugal force, the compression slide 413 slides out of the sliding groove until it contacts the inner wall of the cavity of the grinding disk 47. The volume of the compression chamber 473 between the two compression slides 413 decreases with the rotation. When the compression chamber 473 rotates to the air outlet pipe 471, the compressed air inside is quickly discharged from the air outlet pipe 471. Afterwards, when the compression chamber When the chamber 473 rotates to the air inlet pipe 472, the volume of the compression chamber 473 increases, and negative pressure is formed inside, so that the external air is sucked in from the air inlet pipe 472. Since the air inlet pipe 472 is connected to the inside of the dust suction plate 45 through the multi-way pipe, the air inside the dust suction plate 45 is sucked away to generate negative pressure, so that the dust suction port 451 generates suction. When the ground bone powder falls to the first-layer screening box 49, the powder generated during the crushing and grinding process will be sucked away by the dust suction plate 45 to prevent the dust from adhering to the surface of the qualified bone powder particles and reducing the quality of the finished product. The sucked dust falls from the discharge port at the bottom of the dust suction plate 45 into the dust cabin 4101 of the bottom material box 410.

[0050] When the driving device 43 drives the rotating compression disk 412 to rotate, the vibration ring 411 is synchronously driven to rotate through the transmission wheel 433 and the transmission belt 434, and the control system energizes the electromagnetic head 4111 on the vibration ring 411, and the vibration ring 411 drives the electromagnetic head 4111 to rotate. When the electromagnetic head 4111 rotates above the adsorption head 463, it adsorbs the adsorption head 463, and the adsorption head 463 drives the detection rotating rod 462 to rotate around the detection bracket 461 upward, and the vibration spring 465 at the bottom of the detection rotating rod 462 is compressed, and the vibration spring 465 at the top of the detection rotating rod 462 is stretched, and the screening box 49 connected to the detection rotating rod 462 slides upward along the lower rotating rod 482. After that, after the electromagnetic head 4111 rotates away from the adsorption head 463, under the action of the vibration spring 465, the detection rotating rod 462 rotates to the opposite angle, and then The electromagnetic head 4111 rotates back and forth under the action of the magnet, driving the screening box 49 to vibrate up and down. After that, the electromagnetic head 4111 rotates again to the top of the adsorption head 463 to adsorb the adsorption head 463. This cycle makes the screening box 49 vibrate continuously. During the vibration, the bone powder jumps up and down, and the mixed powder in the bone powder is lifted up and further sucked away by the dust suction plate 45. The bone powder with large particle size remains in the first layer of the screening box 49, and the bone powder with smaller particle size falls into the next layer of the screening box 49 under the action of its own gravity as it vibrates. During the falling process, the powder in the bone powder is again sucked away by the dust suction plate 45. By controlling the size of the magnetic force of the electromagnetic head 4111, the deflection angle of the detection rotating rod 462 can be controlled, thereby realizing the adjustment of the vibration amplitude of the screening box 49. This cycle is repeated until the bone powder is completely screened. Finally, the unqualified bone powder with too small particle size falls into the fine material cabin 4102 at the bottom.

[0051] When the screening is completed, the finished bone powder in the screening box 49 will sink due to gravity, and the detection rod 462 will rotate downward under the combined action of the screening box 49's own gravity and the bone powder's gravity. Since the detection rod 462 rotates on the detection bracket 461 in the form of a lever, the gravity of the bone powder is amplified under the action of the lever, and the other end of the detection rod 462 drives the measuring rod 466 to push the diaphragm 464 upward. The piezoelectric element 467 between the diaphragms 464 is compressed to generate current, and the generated current is transmitted to the control system through the wire. The control system analyzes the increase in the electrical signal by comparing it with the initial value of the electrical signal, thereby calculating the content of bone powder of each particle size, and judges the quality of the preparation by analyzing the content. When the quality is reduced, a maintenance signal is sent to the staff.

[0052] After the bone powder content detection is completed, the control system turns on the electric telescopic rod 2, and the output shaft of the electric telescopic rod 2 drives the bottom support 42 to descend, and the bottom material box 410 and the first motor 44 descend with the bottom support 42, and the output shaft of the first motor 44 drives the lower rotating rod 482 to separate from the upper rotating rod 481. After the bottom support 42 is completely dropped, the staff removes the bottom material box 410, takes out the dust and unqualified aggregate inside, and cleans the bottom material box 410, and then resets the bottom material box 410. The control system drives the bottom support 42 to rise through the electric telescopic rod 2, and the lower rotating rod 482 is connected to the upper rotating rod 481 again through the cross connecting column 483. After that, the control system turns on the electric valve on the bottom screening box 49 and starts the driving device 43. The driving device 43 drives the screening disk to vibrate, and the vibration causes the qualified aggregate to fall quickly from the electric valve and fall into the fine material compartment 4102. This cycle is repeated to achieve layer-by-layer material unloading.

[0053] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
