Description

Technical Field

[0001] The utility model relates to the field of oral model production, in particular to a dental model cutting machine. Background Art

[0002] Dental models are essential tools for research and treatment in dentistry. They are typically made to the exact shape and size of a patient's teeth, simulating the patient's oral environment. Dental models can be made from a variety of materials, such as dental plaster, plastic, or resin, which offer excellent morphological stability and durability.

[0003] The processing flow of dental models includes the following steps: data collection, model making, trimming and adjustment, and model application.

[0004] Existing dental models are usually adjusted using a cutting machine. However, because the surface of the dental model is curved and varies in size, the model is prone to slipping during the cutting process, which in turn leads to a decrease in cutting quality.

[0005] Therefore, a dental model cutting machine is proposed to address the above problems. Utility Model Content

At the same time, after the fan is started, the air inside the clamp will be extracted and the suction cup will be adsorbed on the surface of the dental model, so that the dental model and the clamp can fit tightly, thereby realizing the fixation of the dental model by the device, reducing the displacement and shaking of the dental model during cutting, and improving the accuracy of the cutting machine when cutting the dental model.

[0024] Specific examples are given below.

When working, the dental model is placed on the top of the horizontal plate 103 and close to the clamp 107, and then the device is started. When the dental model and the clamp 107 come into contact, the suction cup 108 is squeezed. When the suction cup 108 is squeezed, the air inside is discharged and adsorbed on the surface of the dental model, and the wooden plug 110 inside the suction cup 108 slides along the suction cup 108 and The suction cup 108 and the clamp 107 are in a connected state, and the suction cup 108 that is not in contact with the dental model will still be blocked by the wooden plug 110. When the device is started, the fan 106 and the cutting mechanism 105 will be powered on. The cutting mechanism 105 will rotate after being powered on, and the fan 106 will extract air from the inside of the clamp 107 through the pipeline after it is started. After the air inside the clamp 107 is extracted, a negative pressure area will be formed. Under the action of atmospheric pressure, the suction cup 108 will be adsorbed and fixed to the dental model. At this time, the device has completed the fixation of the dental model. Then the staff can apply pressure to the corners of the horizontal plate 103. After the horizontal plate 103 is pressurized, the angle will change and the first spring 111 will be in a compressed state. When the angle 03 changes, the dental model will move closer to the cutting mechanism 105 until the dental model and the cutting mechanism 105 come into contact and the cutting mechanism 105 begins to cut; the dental model can be cut by the cutting mechanism 105 by simply pressing the horizontal plate 103, which reduces the operational risk when cutting the dental model, improves the safety of the cutting machine when cutting the dental model, and is beneficial to ensuring the safety of the staff. At the same time, after the fan 106 is started, it will extract the air inside the clamp 107 and make the suction cup 108 adsorb the surface of the dental model, so that the dental model and the clamp 107 can fit tightly, thereby achieving the fixation of the dental model by the device, reducing the displacement and shaking of the dental model during cutting, and improving the accuracy of the cutting machine when cutting the dental model.

[0026] See also Figure 3As shown, a plurality of second springs 22 are fixedly connected to the middle part of the clamp 107; the ends of the adjacent second springs 22 are fixedly connected to a pressure ring 2; the pressure ring 2 and the suction cup 108 are correspondingly arranged; when the dental model squeezes the suction cup 108, the dental model will also squeeze the pressure ring 2. After the pressure ring 2 is subjected to pressure, the pressure will be transferred to the second spring 22 and the second spring 22 will be in a compressed state. Then the second spring 22 will release the elastic potential energy and apply a reaction force to the pressure ring 2. After the pressure ring 2 is subjected to the elastic force of the second spring 22, it will apply pressure to the middle part of the suction cup 108, reducing the air entering the inside of the suction cup 108; through the cooperation of the pressure ring 2 and the second spring 22, when the dental model squeezes the suction cup 108, the pressure ring 2 will squeeze the middle part of the suction cup 108, reducing the interference of external air on the suction cup 108, improving the air tightness of the suction cup 108 itself, enhancing the adsorption effect of the suction cup 108 on the dental model, and further improving the stability of the device in fixing the dental model.

[0027] See also Figure 3 As shown, a plurality of elastic rods 3 are fixedly connected to the middle portion of the suction cup 108; the elastic rods 3 are arranged in a circular array; when the suction cup 108 comes into contact with the dental model, the elastic rods 3 will also come into contact with the dental model, part of the elastic rods 3 will come into contact with the surface of the dental model and bend, while other part of the elastic rods 3 will penetrate into the gaps on the surface of the dental model, thereby increasing the contact area between the device and the dental model; by providing the elastic rods 3, when the dental model presses the suction cup 108, the elastic rods 3 will penetrate into the gaps in the dental model, thereby increasing the contact area between the device and the dental model, increasing the friction between the two, and further enhancing the stability of the dental model during cutting.

[0028] See also Figure 1 and Figure 4As shown, an air pump 4 is symmetrically arranged on the top of the horizontal plate 103; the output end of the air pump 4 is connected to an air chamber 42; a plurality of circular holes 43 are opened in the middle of the air chamber 42; when the cutting mechanism 105 cuts the dental model, debris will be generated and splashed, and after the device is started, the air pump 4 will also be powered on, and the air pump 4 will be started to send air into the air chamber 42, and the air will be ejected from the circular holes 43 in the air chamber 42. The ejected air flow will reach the surface of the dental model, and when the air flow reaches the surrounding of the dental model, the debris generated by the cutting will be diffused, thereby reducing the debris remaining on the surface of the dental model. When the air flow comes into contact with the cutting mechanism 105, the air flow will take away the heat generated by the friction of the cutting mechanism 105 when passing through the cutting mechanism 105; after the air pump 4 inflates the air chamber 42, air flow will be ejected from the circular hole 43 toward the dental model, effectively cleaning the dust and debris generated by cutting on the surface of the dental model, improving the surface finish of the dental model, and facilitating observation during subsequent cutting. At the same time, the air flow will also reach the surface of the cutting mechanism 105 and take away the heat from the surface of the cutting mechanism 105, thereby reducing the surface temperature of the cutting mechanism 105 and extending the service life of the cutting mechanism 105.

[0029] See also Figure 4 As shown, guide plates 5 are hinged on both sides of the air chamber 42; the guide plates 5 are located on the top of the horizontal plate 103; when the air pump 4 is started to blow air toward the surface of the dental model, the airflow will flow along the gap between the two guide plates 5. At this time, the distance between the two guide plates 5 can be adjusted according to the size of different dental models so that the airflow can accurately reach the dental model; by providing the guide plates 5 and adjusting the distance between the two guide plates 5, the airflow can be blown toward dental models of different sizes, thereby realizing the guiding effect of the device on the airflow, so that the device can clean dental models of different sizes, thereby improving the adaptability of the device to cleaning dental models of different sizes.

[0030] See also Figure 4 As shown, the bottom of the horizontal plate 103 is fixedly connected to a connecting plate 6; the middle of the connecting plate 6 is fixedly connected to a plurality of bristles 62; when the staff presses the horizontal plate 103, the angle of the horizontal plate 103 will change, and the horizontal plate 103 will also drive the connecting plate 6 to move when it moves, and the connecting plate 6 will also move with the bristles 62 when it moves, and the bristles 62 will come into contact with the cutting mechanism 105 when it moves, and because the cutting mechanism 105 is constantly rotating, the bristles 62 will rub and clean the surface of the cutting mechanism 105; through the cooperation of the connecting plate 6 and the bristles 62, the cutting mechanism 105 will come into contact with the bristles 62 when it rotates and be cleaned by the bristles 62, thereby reducing the debris remaining on the surface of the cutting mechanism 105, improving the smoothness of the surface of the cutting mechanism 105, and making the cutting mechanism 105 smoother when cutting the dental model.

[0031] See also Figure 1 and Figure 4As shown, a collection box 7 is fixed to the top of the support base 1; the collection box 7 is located at the bottom of the horizontal plate 103; after the air pump 4 is started, air will be blown onto the surface of the dental model, and the debris generated during cutting will diffuse from the gaps around the cutting mechanism 105, and these debris will fall into the interior of the collection box 7; by providing the collection box 7, the debris generated when the cutting machine cuts the dental model will be collected by the collection box 7, thereby reducing the debris remaining on the surface of the device and improving the cleanliness of the device surface.

[0032] Working principle: The elastic sheet 109 is normally attached to the surface of the wooden plug 110, and the wooden plug 110 passes through the hole inside the suction cup 108 and blocks it. When working, the dental model is placed on the top of the horizontal plate 103 and close to the clamp 107, and then the device is started. When the dental model and the clamp 107 come into contact, the suction cup 108 is squeezed. When the suction cup 108 is squeezed, the air inside is discharged and adsorbed to the surface of the dental model, and the wooden plug 110 inside the suction cup 108 slides along the suction cup 108 and makes the suction cup 108 and the clamp 107 in a connected state. The suction cup 108 that is not in contact with the dental model will still be blocked by the wooden plug 110. When the device is started, the fan 106 and the cutting mechanism 105 are driven to pass. When the cutting mechanism 105 is powered on, it will rotate, and when the fan 106 is started, it will draw air from the inside of the clamp 107 through the pipe. After the air inside the clamp 107 is drawn away, a negative pressure area will be formed. Under the action of atmospheric pressure, the suction cup 108 will adsorb and fix the dental model. At this time, the device has completed the fixation of the dental model. Then the staff can apply pressure to the corners of the horizontal plate 103. After the pressure is applied, the angle of the horizontal plate 103 will change and the first spring 111 will be in a compressed state. When the angle of the horizontal plate 103 changes, the dental model will move closer to the cutting mechanism 105 until the dental model and the cutting mechanism 105 come into contact and the cutting mechanism 105 begins to cut. When the dental model squeezes the suction cup 108, the dental model will be cut. When the dental model is pressed, the pressure ring 2 is squeezed. When the pressure ring 2 is under pressure, it transmits the pressure to the second spring 22 and compresses the second spring 22. Then the second spring 22 releases the elastic potential energy and applies a reaction force to the pressure ring 2. When the pressure ring 2 is subjected to the elastic force of the second spring 22, it applies pressure to the middle part of the suction cup 108, thereby reducing the air entering the suction cup 108. When the suction cup 108 comes into contact with the dental model, the elastic rod 3 also comes into contact with the dental model. Part of the elastic rod 3 comes into contact with the surface of the dental model and bends, while the other part of the elastic rod 3 drills into the gap on the surface of the dental model, thereby increasing the contact area between the device and the dental model. When the cutting mechanism 105 cuts the dental model, there will be debris. When the device is started, the air pump 4 is also powered on, and the air pump 4 is started to send air into the air chamber 42. The air in the air chamber 42 is ejected from the circular hole 43, and the ejected airflow reaches the surface of the dental model. When the airflow reaches the dental model, the debris generated by the cutting is diffused, reducing the debris remaining on the surface of the dental model. At the same time, the airflow also comes into contact with the cutting mechanism 105. When the airflow passes through the cutting mechanism 105, it takes away the heat generated by the friction of the cutting mechanism 105. When the air pump 4 is started to blow air toward the surface of the dental model, the airflow flows along the gap between the two guide plates 5. At this time, the distance between the two guide plates 5 can be adjusted according to the size of different dental models, so that the airflow can accurately reach the dental model.When a worker presses the horizontal plate 103, its angle changes. The movement of the horizontal plate 103 also moves the connecting plate 6, which in turn moves the bristles 62 with it. The bristles 62 come into contact with the cutting mechanism 105. Because the cutting mechanism 105 is constantly rotating, the bristles 62 rub and clean the surface of the cutting mechanism 105. Activating the air pump 4 blows air onto the surface of the dental model, causing debris generated during cutting to diffuse through the gaps around the cutting mechanism 105 and fall into the collection box 7.
