Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical processing machinery technology, and in particular relates to a hot melt treatment machine for dental composite materials. Background Technology

[0002] The use of thermoforming for dental composite materials is primarily based on the following principles and clinical advantages: Improved material flowability: Preheating to 37-50℃ significantly reduces the viscosity of the composite resin, making it easier to shape and fill cavity details, reducing the risk of air bubbles and delamination during the procedure; Enhanced material compatibility: Preheating to near body temperature (approximately 37℃) allows the material to adhere better to tooth tissue, reducing the risk of microleakage and thus minimizing postoperative sensitivity; Optimized curing performance: The thermoformed composite resin polymerizes more uniformly during light curing, avoiding shrinkage or edge microcracks caused by uneven internal stress, thus improving the mechanical strength and durability of the restoration; Improved clinical ease of operation: The reduced viscosity after preheating facilitates layered filling and precise shaping by the dentist, especially improving operational efficiency in complex cavity restorations.

[0003] Comparing with Chinese Patent CN220459624U, a hot-melt treatment machine for dental composite materials is disclosed, including a housing. The surface of the housing is provided with a hot-melt assembly, which includes two slide rails, a heat-conducting plate, an electric heating plate, a temperature sensor, a storage box, an adjustment component, and a heat dissipation component. The two slide rails are respectively fixedly installed on both sides of the bottom of the inner wall of the housing, and the heat-conducting plate is slidably connected between the two slide rails. The electric heating plate is fixedly installed at the bottom of the inner wall of the housing. The electric heating plate transfers heat through the heat-conducting plate, which will not directly cause contamination to the electric heating plate. When the heat-conducting plate needs to be cleaned and maintained, it can be pulled out by the handle and placed in the storage box for cooling, which is convenient for later cleaning and maintenance. Then, a new heat-conducting plate can be taken out from the storage box and inserted into the two slide rails, which can quickly complete the replacement and improve work efficiency.

[0004] However, the aforementioned patent requires stopping the machine to disassemble and reassemble the hot-melted dental composite material before it can be reloaded for hot-melting, which greatly increases auxiliary time and reduces production efficiency. Therefore, a new device needs to be designed. Utility Model Content

Before hot melting, the whole unit is transported to the hot melting position. The base plate 101 supports the top plate 103 through the guide column 102. The guide column 102 guides the movement direction of the lifting frame 201 through the limit sliding. The control panel 104 is used to control the completion of the hot melting operation. After all the hot melting is completed, the top plate 103 supports the second motor 105 to drive the fan blade 106 to rotate. Under the protection of the protective cover 107, the airflow is promoted to accelerate heat dissipation.

[0030] In this embodiment: the supporting device includes an adjusting component for adjusting the height, a rotating platform 204 is rotatably mounted on the adjusting component, a driving component providing rotational power is provided on one side of the rotating platform 204, a plurality of lower mold bases 208 are evenly distributed on the rotating platform 204, and a supporting plate 209 is placed inside the lower mold base 208; the adjusting component includes a lifting frame 201, a first electric cylinder 202 is provided at the bottom center of the lifting frame 201, and four limiting guide sleeves 203 are evenly distributed at the four corners of the lifting frame 201; the driving component includes a passive gear ring 205 circumferentially mounted on the rotating platform 204, a driving gear 206 meshing on one side of the passive gear ring 205, and a first motor 207 is provided below the driving gear 206; the limiting guide sleeves 203 and the guide column 102 slide. The bottom end of the first electric cylinder 202 is bolted to the base plate 101. Before hot melting, the whole unit is moved to the hot melting position. The base plate 101 supports the extension and retraction of the first electric cylinder 202 to push the lifting frame 201 up and down. The limit guide sleeve 203 moves up and down along the guide column 102 to ensure that the lifting frame 201 moves up and down stably. Adjust it to a suitable working height. When hot melting, the raw material is first placed on the support plate 209, and then the support plate 209 is placed into the lower mold base 208. The lifting frame 201 supports the first motor 207 to drive the active gear 206 to mesh with the passive gear ring 205 to rotate. The lower mold base 208 is rotated to the bottom of the sealing cover 303 through the rotary table 204. At the same time, the lower mold base 208 that has completed hot melting is rotated to the front to facilitate the disassembly of the support plate 209.

[0031] In this embodiment: the heating device includes a second electric cylinder 301, a cantilever frame 302 is installed at the top of the second electric cylinder 301, and a cover assembly for enclosing and sealing the heating is installed at the end of the cantilever frame 302; the cover assembly includes a sealing cover 303, a heating plate 304 is installed on the inner top surface of the sealing cover 303, and a clearance groove 305 is provided behind the sealing cover 303; the sealing cover 303 and the lower mold base 208 are plugged and plugged in; the lifting frame 201 supports the retraction of the second electric cylinder 301, and drives the sealing cover 303 to descend through the cantilever frame 302, inserting it into the lower mold base 208, covering the support plate 209 and the raw material, while the clearance groove 305 avoids the outward extension of the support plate 209, and then the heating plate 304 heats the raw material for hot melting.

[0032] Working principle: Before hot melting, the whole unit is moved to the hot melting position. The base plate 101 supports the first electric cylinder 202 to extend and push the lifting frame 201 up and down. The limit guide sleeve 203 moves up and down along the guide column 102 to ensure that the lifting frame 201 moves up and down stably and is adjusted to a suitable working height.

[0033] During hot melting, the raw material is first placed on the support plate 209, and then the support plate 209 is placed into the lower mold base 208. The lifting frame 201 supports the first motor 207 to drive the active gear 206 to mesh with the passive gear ring 205 to rotate. The rotating table 204 drives the lower mold base 208 to rotate below the sealing cover 303. At the same time, the lower mold base 208, which has completed hot melting, rotates to the front to facilitate the removal of the support plate 209. Then, the lifting frame 201 supports the second electric cylinder 301 to retract, and the cantilever frame 302 drives the sealing cover 303 to descend and insert it into the lower mold base 208, covering the support plate 209 and the raw material. The clearance groove 305 avoids the extended part of the support plate 209. Then, the heating plate 304 heats the raw material for hot melting. After completion, the above steps are followed. When the support plate 209 rotates to the front, it can be removed.

[0034] After all the heat melting is completed, the top plate 103 supports the second motor 105 to drive the fan blades 106 to rotate, which promotes airflow under the protection of the protective cover 107 and accelerates heat dissipation.
