Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of artificial bone powder preparation, and particularly relates to an artificial bone powder preparation device with particle size screening function. BACKGROUND

[0002] Artificial bone powder has excellent bone regeneration and repair ability and plays an important role in oral implant surgery and other fields. It becomes an indispensable part of modern oral medicine due to its unique properties and wide application prospects. Through close adhesion with the original bone, the artificial bone powder can stimulate the activity of bone cells and promote the formation of new bone, thereby restoring the support structure of the teeth.

[0003] The preparation of artificial bone powder needs to be ground. When the existing equipment is ground, bone powder particles of different particle sizes are generated. The bone powder particles can be used in different parts according to the particle size. However, a large amount of fine powder is generated during grinding, which can cause blockage of medical equipment and cannot be used in bone graft surgery. Not only does this lead to waste of bone powder raw materials, but also increases the preparation steps of artificial bone powder and reduces production efficiency. SUMMARY

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

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

[0006] A control system is arranged in the support table, and the control system is used for controlling the whole artificial bone powder preparation device.

[0007] When the bone powder content detection is completed, the control system starts the electric telescopic rod, the output shaft of the electric telescopic rod drives the bottom support to descend, the bottom 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 completely descends, the staff takes down the bottom box, takes out the dust and unqualified aggregate in the bottom box, and cleans the bottom box, then resets the bottom box, the control system drives the bottom support to ascend through the electric telescopic rod, the lower rotating rod and the upper rotating rod are connected again through the cross connecting column, then the control system opens the electric valve on the bottommost layer of the screening box, and starts the driving device, the driving device drives the screening disc to vibrate, the vibration makes the qualified aggregate quickly fall from the electric valve and drop into the fine material cabin, and the process is repeated, so as to realize layer-by-layer discharging.

[0008] The crushing preparation device further comprises a plurality of vibration detectors installed in the preparation shell, a screening box movably connected to the vibration detector, the screening box being in sliding connection with the lower rotating rod, a plurality of dust absorption plates installed in the preparation shell, a bottom box provided on the bottom support and in rotary connection with the lower rotating rod, a driving device installed in the preparation shell, a plurality of vibration rings rotatably installed on the dust absorption plates, the driving device being in rotary connection with the vibration rings, and a plurality of electromagnetic heads provided at the bottom end of the vibration rings.

[0009] The crushing preparation device further comprises a rotary compression disc eccentrically and rotatably installed in the grinding disc, the rotary compression disc being in rotary connection with the driving device, a plurality of sliding grooves provided on the rotary compression disc, and a plurality of compression sliding plates slidably installed in the sliding grooves.

[0010] The driving device comprises a second motor installed at the bottom end of the preparation shell, a second rotating rod penetrating through the preparation shell and installed with the second motor output shaft, the second rotating rod being in rotary connection with the preparation shell at the top end, a plurality of transmission wheels installed on the second rotating rod, and the transmission wheels being in rotary connection with the inside of the vibration rings and the rotary compression disc through transmission belts.

[0011] The control system activates the second motor, which drives the second rotating rod to rotate. The second rotating rod drives the rotating compression disc to rotate eccentrically via the transmission wheel and transmission belt. The rotating compression disc drives the compression vanes to rotate. Under the action of centrifugal force, the compression vanes slide out from the sliding groove until they contact the inner wall of the cavity of the grinding disc. The volume of the compression chamber between the two compression vanes decreases as it rotates. When the compression chamber rotates to the air outlet, the compressed air inside is quickly discharged from the air outlet. Then, when the compression chamber rotates to the air inlet, the volume of the compression chamber increases, and a negative pressure is formed inside, causing external air to be drawn in from the air inlet. Since the air inlet is connected to the inside of the dust collection plate through the multi-port pipe, the air inside the dust collection plate is drawn away, creating a negative pressure, which in turn generates suction at the dust collection port. When the ground bone powder falls into the first layer screening box, the powder generated during the crushing and grinding process is drawn away by the dust collection plate to prevent dust from adhering to the surface of qualified bone powder particles and reducing the quality of the finished product. The dust drawn away falls into the dust chamber of the bottom material box from the discharge port at the bottom of the dust collection plate.

[0012] The vibration detector includes a detection bracket installed inside the preparation shell. A detection rod is rotatably mounted on the detection bracket. A movable connector is installed at one end of the detection rod. An adsorption head is installed on the detection rod. A measuring rod is installed on the detection rod. A vibration spring is installed between the detection rod and the detection bracket. A diaphragm is installed inside the detection bracket. Piezoelectric elements are installed between the diaphragms. The movable connector is movably connected to a sieving connector.

[0013] When the drive unit rotates the rotary compression disc, it synchronously drives the vibrating ring to rotate via the transmission wheel and transmission belt. The control system energizes the electromagnetic head on the vibrating ring, causing the vibrating ring to drive the electromagnetic head to rotate. When the electromagnetic head rotates above the adsorption head, it adsorbs the adsorption head. The adsorption head moves upward, causing the detection rod to rotate around the detection bracket. The vibration spring at the bottom of the detection rod is compressed, while the vibration spring at the top of the detection rod is stretched. The screening box connected to the detection rod slides upward along the lower rod. After the electromagnetic head moves away from the adsorption head, the detection rod rotates in the opposite direction under the action of the vibration spring, and then reciprocates under inertia, causing the screening box to vibrate up and down. Afterward, the electromagnetic head rotates away from the adsorption head. The magnetic head rotates again to above the adsorption head and adsorbs it. This cycle repeats, causing the sieving box to vibrate continuously. During vibration, the bone powder jumps up and down, and the powder mixed in the bone powder is lifted up and further sucked away by the dust suction plate. Large-diameter bone powder remains in the first sieving box, while smaller-diameter bone powder falls into the next sieving box under its own gravity. During the fall, the powder in the bone powder is sucked away by the dust suction plate again. By controlling the magnitude of the magnetic force of the electromagnetic head, the deflection angle of the detection rod can be controlled, thereby adjusting the vibration amplitude of the sieving box. This cycle continues until the bone powder is completely sieved. Finally, unqualified bone powder with too small a particle size falls into the fine material bin at the bottom.

[0014] When the screening ends, the finished bone powder in the screening box will sink under the gravity, and the detection rotating rod will rotate downward under the joint action of the gravity of the screening box and the bone powder, and the detection rotating rod will rotate on the detection support in the form of a lever, the gravity of the bone powder is enlarged under the lever action, the detection rotating rod drives the measuring rod to push up the diaphragm at the other end, the piezoelectric element between the diaphragms is pressed to generate an electric current, the generated electric current is transmitted to the control system through the wire, the control system compares with the initial value of the electric signal, analyzes the increase of the electric signal, and calculates the content of the bone powder of each particle size, judges the quality of the preparation through the analysis of the content, and sends a maintenance signal to the staff when the quality decreases.

[0015] The grinding crusher comprises a crushing cone head, a connecting round head mounted at the top end of the crushing cone head, and a positioning rod movably connected with the connecting round head.

[0016] The raw materials are poured from the top end of the preparation shell, and the control system starts the first motor after the raw materials enter the crushing chamber, 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.

[0017] The dust absorption plate is provided with a plurality of dust suction ports, and the dust absorption plate is a hollow structure.

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

[0019] Compared with the prior art, the beneficial effects of the present application are:

[0020] 1. The drive device drives the rotating compression disc and compression vane to rotate, which, together with the compression chamber inside the grinding disc, creates negative pressure on the dust collection plate, thereby achieving the effect of removing powder and preventing dust from adhering to the surface of qualified bone meal particles and reducing the quality of the finished product. At the same time, the dust sucked up falls from the discharge port at the bottom of the dust collection plate into the dust chamber of the bottom material box, achieving the effect of automatic powder collection.

[0021] 2. The drive device synchronously drives the vibrating ring to rotate. The engagement and disengagement of the electromagnetic head and the adsorption head cause the detection rod to vibrate the screening box under the cooperation of the vibration spring. The vibration causes the bone powder to jump up and down, which not only raises the mixed powder in the bone powder and allows it to be further sucked away by the dust suction plate, but also allows the smaller particles of bone powder to fall into the next screening box under their own gravity, achieving the purpose of multi-stage screening and purification. Finally, the fine material bin is used to collect the unqualified bone powder.

[0022] 3. In a static state, the rotating rod, under the combined action of the weight of the sieving box and the weight of the bone meal, drives the measuring rod to deflect and squeeze the piezoelectric element. The piezoelectric element transmits an electrical signal to the control system. The control system compares the signal with the initial value to analyze the increase in the signal, thereby calculating the content of bone meal of each particle size. By analyzing the content, the quality of the preparation is determined. When the quality decreases, a maintenance signal is sent to the staff. At the same time, the lever principle amplifies the weight of the bone meal, making it easier to generate a more obvious electrical signal, thus making the detection of bone meal content more accurate.

[0023] 4. The grinding and crushing process utilizes a grinding and crushing device to simultaneously crush and grind the raw material. First, it is crushed into uniform blocks, and then finely ground to gradually achieve the required bone meal size. This multi-stage refining process ensures more uniform bone meal particles and avoids excessive waste. The grinding cone and grinding disc feature a conical design, with the grinding cone eccentrically mounted. This prevents large-diameter bone meal particles from passing through the gap between the grinding cone and the bottom of the grinding disc, ensuring they are ground to the required size before falling, thus preventing excessively large bone meal particles.

[0024] 5. The electric telescopic rod drives the bottom material box on the base to descend, completing the automatic feeding of powder and unqualified bone meal. Then, the drive device drives the screening box to vibrate, so that qualified aggregate falls quickly from the electric valve, realizing the graded feeding of qualified bone meal.

[0048] The working principle of the present application is as follows: the raw material is poured into the preparation shell 41 from the top end. 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.
