Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an oral plaster model trimming device. Background Art

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used on the human body. In the field of oral restoration, when making dentures (such as porcelain teeth, complete dentures), it is necessary to first obtain a plaster model of the patient's oral cavity. This original model may have some defects, such as uneven surfaces, sharp edges, or excess plaster parts. The trimming device can trim the model so that the denture can better fit the patient's oral cavity.

[0003] During the process of making oral models, situations such as excess plaster and uneven edges may occur. This device can remove the excess plaster and make the shape of the model conform to the actual needs of the oral structure. For example, it can smooth the edges of the tooth model or trim the correct shapes of the crown and root. In terms of mechanical trimming, the device is usually equipped with cutting tools. When the device is turned on, the tools will rotate at high speed, and the cutting edges of the tools are used to cut the excess parts on the plaster model.

[0004] In the prior art, some plaster model trimming devices are difficult to remove dust. The plaster dust will affect the trimming accuracy because the dust accumulates on the working parts of the device or the model surface, interfering with the vision and making it difficult for the operator to see the details of the model clearly. As a result, errors will occur during trimming, affecting the final quality of the model. Plaster dust is easily inhaled by the human body.

The left side of the fixed barrel 1 is fixedly connected with a dust removal mechanism 4. The dust removal mechanism 4 prevents dust from spreading in the air. The inside of the dust removal mechanism 4 is fixedly connected with a vibration mechanism 5. The main function of the vibration mechanism 5 is to prevent the filter plate 403 from being blocked. The grinding mechanism 2 includes a motor 201. The bottom of the motor 201 is fixedly connected to the bottom inner wall of the fixed barrel 1. The driving end of the motor 201 is fixedly connected with a rotating rod 202. The top of the rotating rod 202 is fixedly connected with a positioning ring 203.

[0023] Specifically: The motor 201 serves as a power source and is fixed to the bottom inner wall of the fixed barrel 1, providing stable rotational power for the entire grinding process. The rotating rod 202 connects the driving end of the motor 201 and the positioning ring 203, transmitting the rotational motion of the motor. The positioning ring 203 is used to detachably fix the tool 204, ensuring the stability of the tool during high-speed rotation. The tool 204 directly acts on the gypsum model, grinding and trimming it, realizing the preliminary shaping and surface treatment of the model, ensuring the dimensional accuracy and surface flatness of the model, and meeting the subsequent processing requirements.

[0024] Please refer to the attached Figure 3 and the attached Figure 4, the disassembly mechanism 3 includes two hooks 301. The bottoms of the two hooks 301 are rotatably connected to the front and rear sides inside the rotating rod 202. A telescopic spring 302 is fixedly connected to the adjacent sides of the two hooks 301. The adjacent sides of the two telescopic springs 302 are each rotatably connected to a connecting rod 303. The adjacent sides of the two connecting rods 303 are rotatably connected to a moving block 304. A sliding plate 305 is slidably connected inside the cutter 204.

[0026] Please refer to the appendix Figure 2 and the appendix Figure 3 and the appendix Figure 5, the dust removal mechanism 4 includes a fixed box 401. The left side of the fixed box 401 is fixedly connected to the right side of the fixed barrel 1. Three suction pipes 402 are fixedly connected to the top of the fixed box 401. A filter plate 403 is slidably connected to the inner wall of the fixed box 401. A rotating column 405 is rotatably connected inside the fixed box 401. A first bevel gear 404 is fixedly connected to the right side of the rotating column 405. A first helical gear 406 is fixedly connected to the outside of the rotating column 405. A protective box 407 is rotatably connected to the outside of the rotating column 405. A rotating shaft 409 is rotatably connected to the bottom end inside the protective box 407. A second helical gear 408 is fixedly connected to the outside of the rotating shaft 409. A fan 410 is fixedly connected to the right side of the rotating shaft 409. By driving the rotation of the motor 201 and the rotating rod 202, the motor drives the second bevel gear 411 to rotate, thereby transmitting power through the gear set to drive the fan 410 to generate suction. The fan, in combination with the suction pipes 402, ensures that the dust in the air is removed in a timely manner. The connection between the fan and the rotating column 405 and the rotating shaft 409 ensures the stable transmission of power, enabling the fan to operate efficiently for a long time without excessive wear. A second bevel gear 411 is fixedly connected to the outside of the rotating rod 202. The external teeth of the second bevel gear 411 are meshed with the external teeth of the first bevel gear 404. The external teeth of the first helical gear 406 are meshed with the external teeth of the second helical gear 408. The first helical gear 406 drives the second helical gear 408 to rotate. The outside of the rotating column 405 is rotatably connected to the inside of the right side of the fixed barrel 1, and the outside of the rotating column 405 is rotatably connected to the left side inside the fixed box 401, improving the stability of the rotating column 405.

[0027] Specifically: The fixed box 401 provides an installation foundation and space for the dust removal component, and is connected to the fixed barrel 1 on the left side to ensure the continuity of dust collection. The three suction pipes 402 suck dust from inside the barrel body, above the barrel body, and the side wall of the barrel body respectively, comprehensively covering the dust generation area. The filter plate 403 is used to filter the dust in the air to prevent it from spreading out again. The rotating column 405 is a key component for power transmission. The first bevel gear 404 on its right side is meshed with the second bevel gear 411 on the rotating rod 202, transmitting power to the first helical gear 406, and then driving the second helical gear 408 and the rotating shaft 409 to rotate, causing the fan 410 to rotate and generate suction, realizing efficient dust removal for the mold repair device, reducing the harm of dust to the health of operators and the adverse effects on equipment.

[0028] Please refer to the appendix Figures 6 - 8, the vibration mechanism 5 includes a fixed plate 502. The vibration mechanism 5 enables the filter plate to shake off the attached dust through vibration, thereby ensuring good air permeability and filtration effect of the filter plate. After each vibration, the reset spring 508 will restore the filter plate to its initial position to ensure that it is always in the best working state. There are sliding structures connected to the fixed rods 506 at the four corners inside the filter plate, so as to ensure that the filter plate will not be deformed or damaged during vibration. The front and rear sides of the fixed plate 502 are fixedly connected to the inner walls of the front and rear sides of the fixed box 401. A disc 501 is fixedly connected to the outside of the rotating shaft 409. The front and rear sides of the right part of the fixed plate 502 are fixedly connected with support columns 503. A sliding frame 504 is slidably connected to the outside of the two support columns 503. The inner walls of the front and rear sides of the fixed box 401 are fixedly connected with fixed frames 505. The upper and lower sides of the left part of the fixed frame 505 are fixedly connected with fixed rods 506. A square plate 507 is fixedly connected to the left side of the two fixed rods 506. A reset spring 508 is sleeved on the outside of the fixed rod 506. The four inner corners of the filter plate 403 are slidably connected to the outside of the four fixed rods 506. The right side of the sliding frame 504 is in contact with the left side of the filter plate 403.

[0029] Specifically: The fixed plate 502 is fixed to the inner walls of the front and rear sides of the fixed box 401, providing a stable support for the support columns 503 and the fixed frames 505. When the rotating shaft 409 rotates, it drives the disc 501 to rotate. The disc 501 contacts the inner wall of the sliding frame 504, pushing the sliding frame 504 to slide on the support column 503, and then driving the filter plate 403 to move and compress the reset spring 508. After the rotating shaft 409 rotates to a certain position, under the reaction force of the reset spring 508, the filter plate 403 vibrates, shaking off the adsorbed gypsum dust, maintaining the air permeability and filtration performance of the filter plate, ensuring the continuous and efficient operation of the dust removal system, and maintaining the air quality around the die repair device.

[0030] The bottom of the contact block 308 is in contact with the top of the moving block 304. The contact block 308 drives the moving block 304 to move. The outside of the sliding plate 305 is slidably connected to the inner wall of the cutter 204. Square openings are provided on the front and rear sides of the cutter 204. The outside of the hook 301 is engaged with the inner wall of the square opening, realizing the disassembly of the cutter 204 of the gypsum model die repair device. The outside of the disc 501 is in contact with the inner wall of the sliding frame 504. The disc 501 drives the sliding frame 504 to slide. The right side of the reset spring 508 is fixedly connected to the left side of the fixed frame 505. The far sides of the two square plates 507 are fixedly connected to the inner walls of the front and rear sides of the fixed box 401. The outside of the fan 410 is fixedly connected to the inside of the right side of the fixed box 401, improving the stability of the fan 410. The right side of the support column 503 is fixedly connected to the inner wall of the right side of the fixed box 401, improving the stability of the support column 503. The inner front and rear sides of the filter plate 403 are slidably connected to the outside of the two support columns 503.

[0031] Specifically, the vertical pressing action of the button 307 is converted into the rotational action of the connecting rod 303, thereby driving the rotation of the hook 301, providing the key mechanical transmission for the disassembly of the cutting tool 204, enabling the operator to easily release the locking of the cutting tool 204 by the hook 301, achieving the rapid disassembly and replacement of the cutting tool. The stable guiding movement of the sliding plate 305 inside the cutting tool 204 ensures that the button 307 and the contact block 308 can move along the predetermined trajectory, accurately triggering the unlocking mechanism of the hook 301. The smooth sliding of the filter plate 403 on the support column 503, in cooperation with the actions of the disc 501 and the sliding frame 504, enables the filter plate 403 to achieve efficient vibration dust removal.

[0032] Working principle: When dust removal is required for the dust generated after grinding, by starting the motor 201, the motor 201 drives the rotating rod 202 to rotate, causing the rotating rod 202 to drive the second bevel gear 411 to rotate, thereby enabling the second bevel gear 411 to drive the first bevel gear 404 to rotate. The first bevel gear 404 drives the rotating column 405 to rotate, causing the rotating column 405 to drive the first helical gear 406 to rotate, resulting in the first helical gear 406 driving the second helical gear 408 to rotate. After the second helical gear 408 drives the rotating shaft 409 to rotate, the rotating shaft 409 drives the fan 410 to rotate. By sucking through the suction pipes 402 from inside the barrel body, above the barrel body, and the side wall of the barrel body respectively, dust removal of the plaster model trimming device is achieved, reducing the diffusion of dust in the air. After the plaster dust is effectively removed, the risk of the operator inhaling harmful dust will be greatly reduced, effectively avoiding the occurrence of respiratory diseases.

[0033] When disassembly is required, after pressing the button 307, the button 307 drives the sliding plate 305 to slide, causing the sliding plate 305 to drive the tension spring 306 to compress. The button 307 drives the contact block 308 to move, enabling the contact block 308 to drive the moving block 304 to move, resulting in the moving block 304 driving the connecting rod 303 to rotate. Thereby, the connecting rod 303 drives the hook 301 to rotate. After the hook 301 compresses the telescopic spring 302, the cutting tool 204 is disengaged from the positioning ring 203, achieving the disassembly of the cutting tool 204 of the plaster model trimming device, ensuring the stable cutting performance of the trimming device, maintaining the machining accuracy of the model, reducing the trimming error caused by the dullness of the cutting tool 204, and guaranteeing the production efficiency and quality.

[0034] When it is necessary to prevent the filter plate 403 from being blocked, after rotating through the rotating shaft 409, the rotating shaft 409 drives the disc 501 to rotate, causing the disc 501 to drive the sliding frame 504 to slide. The sliding frame 504 drives the filter plate 403 to move, compressing the return spring 508 driven by the filter plate 403. When the rotating shaft 409 rotates to a certain position, under the reaction force of the return spring 508, the filter plate 403 is vibrated, which helps to shake off the gypsum dust adsorbed on the surface of the filter plate 403. When a certain amount of dust accumulates on the filter plate 403, the filtration efficiency will decrease. By vibration, the dust can be separated from the filter plate 403, keeping the filter plate 403 with good air permeability and filtration performance, so as to continuously and effectively capture the dust in the air and ensure the air quality around the mold repair device.
