Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis mold cleaning, and in particular to a device for washing and drying dental prostheses. Background Technology

[0002] Dental molds are a core auxiliary component in the denture fabrication process. Their surface cleanliness and dryness directly affect the molding accuracy, fit, and subsequent stability of the denture. During the denture fabrication process, after processes such as pouring and finishing, resin debris, plaster powder, adhesive, and other impurities may remain on the surface of the mold. If these are not thoroughly removed, they can lead to surface defects and fit errors after the denture is formed, affecting the restorative outcome.

[0003] Currently, the industry mainly uses manual alcohol wiping or direct rinsing to clean dental prostheses. However, these traditional methods have significant technical drawbacks: Firstly, alcohol, as a volatile and flammable liquid, easily generates alcohol vapor during wiping or rinsing. When the concentration of alcohol vapor in the environment reaches the explosive limit, it can easily cause a fire or explosion accident if it encounters static electricity, a source of ignition, or other similar conditions, posing a serious safety hazard to the personal safety of operators and the production environment. Secondly, manual operation is limited by manpower and operating space, allowing only a small number of dental prostheses to be cleaned at a time. Furthermore, the cleaning effect depends on the operator's experience, making it difficult to guarantee the uniformity and thoroughness of the cleaning. This not only leads to low cleaning efficiency but may also affect the pass rate of subsequent dental prosthesis processing due to residual impurities.

[0004] Therefore, there is an urgent need to develop a washing and drying equipment for denture molds that can achieve batch processing, thorough cleaning, and safety and reliability. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a water washing and drying device for denture molds that can achieve batch processing, thorough cleaning, and safety and reliability.

[0006] The technical solution is as follows: A washing and drying device for dental prostheses includes a cabinet, a cover, a working box, a conveying mechanism, a feeding frame, and a washing and drying mechanism. The cover is fixed to the top of the cabinet, but the top of the cover is not completely closed. A feed inlet is left on the left side of the cabinet. A working box is set in the upper part of the cabinet. The left side of the working box is an ultrasonic cleaning zone, and the right side of the working box is a washing and drying zone. A washing and drying mechanism is set in the washing and drying zone. A conveying mechanism extends to the left and right sides of the working box. The feeding frame containing the dental prosthesis is placed on the conveying mechanism from the feed inlet. The feeding mechanism conveys the feeding frame from left to right. When the feeding frame passes through the ultrasonic cleaning zone, the dental prosthesis undergoes ultrasonic cleaning. When the feeding frame passes through the washing and drying zone, the washing and drying mechanism rinses and dries the dental prosthesis.

[0007] Furthermore, the upper ultrasonic oscillator on the left side of the machine housing includes a concave cover, a liquid inlet connector, a concave isolation cover, an overflow connector, a first discharge connector, a lower ultrasonic oscillator, and a second discharge connector. The concave cover is located in the upper part of the cabinet. The left side of the concave cover is a downward-recessed ultrasonic cleaning area, and the right side of the concave cover is a downward-recessed cleaning and drying area. The connection between the ultrasonic cleaning area and the cleaning and drying area is an upward-sloping shape. A concave isolation cover is installed at this slope. After the concave isolation cover is connected to the concave cover, there is only an opening at the top. A lower ultrasonic oscillator is installed on the concave cover at the bottom of the ultrasonic cleaning area. The lower ultrasonic oscillator is below the upper ultrasonic oscillator. A liquid inlet connector is installed on the concave cover at the bottom of the ultrasonic cleaning area. An overflow connector is installed on the concave cover below the concave isolation cover. A first discharge connector is installed at the bottom of the ultrasonic cleaning area, and a second discharge connector is installed at the bottom of the cleaning and drying area.

[0008] Furthermore, the material conveying mechanism includes a material conveying motor, a drive shaft, a drive chain assembly, a guide plate, and a material conveying shaft. The drive shaft is rotatably mounted on both the left and right sides inside the concave cover. The material conveying motor is fixedly connected to the concave cover. The output shaft of the material conveying motor is connected to the end of one of the drive shafts. The drive chain assemblies are connected between the front and rear parts of the drive shaft. The front and rear walls of the middle part of the concave cover are provided with guide plates that slope upward from left to right. The chains of the drive chain assemblies are embedded in the guide plates. At least two sets of material conveying shafts are provided on the chains of the drive chain assemblies.

[0009] Furthermore, the feeding frame consists of two rotating mesh frames connected at the top and bottom. The dental model is placed between the two mesh frames. The bottom of the feeding frame is symmetrically provided with material-holding grooves, which are located on the moving path of the feeding shaft.

[0010] Furthermore, the cleaning and drying mechanism includes a horizontal moving module, an adapter plate, a cleaning nozzle, a liquid inlet head, an air inlet head, an air suction head, and an external connector. The horizontal moving module is horizontally installed on the right side inside the machine cover. The adapter plate is connected to the slider of the horizontal moving module. The cleaning nozzle is installed on the adapter plate. The cleaning nozzle is located in the cleaning and drying area and is positioned on the upper and lower sides of the material conveying mechanism. The cleaning nozzle has a liquid inlet head and an air inlet head. An air suction head and an external connector are provided on the right side wall of the concave cover. The external connector is connected to the liquid inlet head through a pipeline, and the air suction head is connected to the air inlet head through a pipeline.

[0011] Furthermore, it also includes limiting plates, with limiting plates installed on the left side of the machine cover on both the front and rear sides of the feeding frame.

[0012] Furthermore, it also includes a wastewater treatment mechanism. The wastewater treatment mechanism is located on the right side of the cabinet. The wastewater treatment mechanism includes a housing, a curing lamp, a wastewater inlet connector, a baffle plate, a filter, and a drain pipe. The housing is located on the right side of the cabinet. The wastewater inlet connector is located on the upper wall of the housing. The wastewater inlet connector is connected to the overflow connector, the first discharge connector, and the second discharge connector via pipes. A drain channel is inclined at the top of the housing. A curing lamp is located on the housing above the drain channel. Baffle plates are symmetrically arranged at the bottom of the drain channel. A filter is slidably placed between the baffle plates. The drain channel above the filter has a hole. The filter communicates with the drain channel through the hole. The lower wall of the housing is inclined. A drain pipe is located on the lowest side wall of the inclined position of the lower wall of the housing.

[0013] Furthermore, the wastewater treatment device also includes a first baffle plate. The first baffle plate is installed near the wastewater inlet inlet of the discharge channel, and there is a gap between the bottom of the first baffle plate and the lower wall of the discharge channel.

[0014] Furthermore, the wastewater treatment device also includes a second baffle plate, which is installed in the discharge channel. The second baffle plate is located above the filter, and there is a gap between the second baffle plate and the lower wall of the discharge channel. The bottom gap height of the second baffle plate is less than the bottom gap height of the first baffle plate.

[0015] The beneficial effects of this utility model are as follows: This utility model only requires placing multiple dental prostheses in a feeding frame, which is then conveyed from left to right. During the conveying process, the dental prostheses are first ultrasonically cleaned, then rinsed with water, and finally dried, achieving the effects of batch processing, thorough cleaning, and safety and reliability. The first baffle plate spreads and disperses the flowing liquid, which is then discharged into the area below the curing lamp through the gap below the first baffle plate. The curing lamp can better cure the resin in the liquid, turning the resin into granules. The second baffle plate allows the flowing liquid to stay under the curing lamp for a longer time, ensuring that the resin in the liquid is fully cured. Attached Figure Description

Detailed Implementation

[0028] The present invention will now be described in detail with reference to the accompanying drawings.

[0029] Example: A device for washing and drying denture molds, such as... Figures 1-9As shown, the device includes a cabinet 1, a cover 2, a work box 3, a conveying mechanism 4, a discharge frame 5, and a cleaning and drying mechanism 7. The top of the cabinet 1 is fixed to the cover 2 with bolts. The top of the cover 2 is not completely closed. The left side of the cabinet 1 has an inlet, and the right side has an outlet. The work box 3 is located in the upper part of the cabinet 1. The left side of the work box 3 is an ultrasonic cleaning area 32, where the dental prosthesis mold is ultrasonically cleaned. The right side of the work box 3 is a cleaning and drying area 35, where the cleaning and drying mechanism 7 is located. The dental prosthesis mold is rinsed by water and dried by air. The conveying mechanism 4 extends to the left and right sides of the work box 3. The discharge frame 5 containing the dental prosthesis mold is placed on the conveying mechanism 4 from the inlet. The conveying mechanism 4 transports the discharge frame 5 from left to right. When the discharge frame 5 passes through the cleaning and drying area 35, the cleaning and drying mechanism 7 rinses and dries the dental prosthesis mold.

[0030] A washing and drying device for dental prostheses, compared with the prior art: When cleaning the dental prostheses, the prostheses are first placed in a feeding frame 5, which can be stacked from bottom to top. Then, the conveying mechanism 4 is controlled to move the feeding frame 5 containing the dental prostheses from bottom to top, transporting it from left to right. When the feeding frame 5 containing the dental prostheses passes through the ultrasonic cleaning zone 32, residual resin and impurities on the dental prostheses are broken up by ultrasonic waves. Then, the feeding frame 5 containing the dental prostheses begins to move upwards. The dental prosthesis molds are conveyed until the feeding frame 5 containing the dental prosthesis molds moves to the cleaning and drying area 35. At this time, the dental prosthesis molds are rinsed and dried by the cleaning and drying mechanism 7. After drying, the dental prosthesis molds are sent out from the right side of the cabinet 1. This application only requires placing multiple dental prosthesis molds in the feeding frame 5. The feeding frame 5 containing the dental prosthesis molds is conveyed from left to right. During the conveying process, the dental prosthesis molds are first ultrasonically cleaned and then rinsed with water. After rinsing, the dental prosthesis molds are dried, achieving the effect of batch processing, thorough cleaning and safety.

[0031] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the upper ultrasonic oscillator 21 is located on the left side inside the housing 2. The working box 3 includes a concave cover 31, a liquid inlet connector 33, a concave isolation cover 34, an overflow connector 36, a first discharge connector 37, a lower ultrasonic oscillator 38, and a second discharge connector 39. The concave cover 31 is fixedly installed in the upper part of the cabinet 1 by bolts. The left side of the concave cover 31 is a downwardly recessed ultrasonic cleaning area 32, and the right side of the concave cover 31 is a downwardly recessed cleaning and drying area 35. The connection between the ultrasonic cleaning area 32 and the cleaning and drying area 35 is an upwardly sloping section, where a concave isolation cover 34 is installed. After being connected to the concave cover 31, the ultrasonic cleaning zone 32 has an opening only at the top. A lower ultrasonic oscillator 38 is installed on the concave cover 31 at the bottom of the ultrasonic cleaning zone 32, below the upper ultrasonic oscillator 21. A liquid inlet 33 is installed on the concave cover 31 at the bottom of the ultrasonic cleaning zone 32, through which liquid is injected into the ultrasonic cleaning zone 32. An overflow 36 is installed on the concave cover 31 below the concave isolation cover 34. When the liquid level in the ultrasonic cleaning zone 32 exceeds the upper surface of the concave isolation cover 34, the liquid enters the concave isolation cover 34 and is then discharged through the overflow 36. In addition, to drain excess liquid, the bottom of the ultrasonic cleaning zone 32 is equipped with a first discharge connector 37 with a valve. Opening the first discharge connector 37 drains the liquid in the ultrasonic cleaning zone 32. The bottom of the cleaning and drying zone 35 is equipped with a second discharge connector 39, through which the liquid used to rinse the denture mold is discharged. Liquid is injected into the ultrasonic cleaning zone 32 through the liquid inlet connector 33 until the liquid level in the ultrasonic cleaning zone 32 exceeds the denture mold. Then, the upper ultrasonic oscillator 21 and the lower ultrasonic oscillator 38 are controlled to operate. The ultrasonic cleaning zone 32 drives the liquid in the ultrasonic cleaning zone to generate synchronous high-frequency vibration. During the liquid vibration, countless tiny bubbles (vacuum cavities) are rapidly formed. The bubbles are generated and burst instantly under pressure changes, releasing a powerful instantaneous impact force (up to thousands of atmospheres). The impact force acts on the dental model in the liquid, achieving the effect of cleaning (removing impurities from the surface of the dental model). The dental model that has been ultrasonically cleaned continues to be transported to the right. When the dental model moves to the cleaning and drying zone 35, the dental model is rinsed and dried by the cleaning and drying mechanism 7. The rinsing water is discharged from the equipment through the second discharge connector 39.

[0032] like Figure 3 and Figure 4As shown, the material conveying mechanism 4 includes a material conveying motor 41, a drive shaft 42, a drive chain assembly 43, a guide plate 44, and a material conveying shaft 45. The drive shaft 42 is rotatably mounted on both the left and right sides of the concave cover 31 via bearing seats. The material conveying motor 41 is bolted to the rear right side of the concave cover 31. The output shaft of the material conveying motor 41 is connected to the rear end of the right-side drive shaft 42. Drive chain assemblies 43 are connected between the front and rear sections of the drive shaft 42. Guide plates 44, inclined upwards from left to right, are provided on both the front and rear walls of the middle section of the concave cover 31. The chains of the drive chain assembly 43 are embedded in the guide plates 44. Due to the action of the guide plates 44, the material feeding frame 5 can be conveyed from left to right and upwards. At least two sets of material conveying shafts are provided on each chain of the drive chain assembly 43. 45. The feeding shaft 45 extends inward; the feeding frame 5 consists of two rotatably connected mesh frames, with the dental prosthesis mold placed between the two mesh frames. The feeding frame 5 has symmetrically opened material-holding grooves 51 at its bottom, which are located on the moving path of the feeding shaft 45. The feeding frame 5 containing the dental prosthesis mold is placed on the left side of the concave cover 31. Then, the feeding motor 41 is controlled to rotate clockwise, which in turn drives the transmission shaft 42 to rotate clockwise, thereby driving the transmission chain assembly 43 to rotate clockwise, causing the feeding shaft 45 to rotate clockwise. When the feeding shaft 45 moves to the position of the material-holding groove 51, the feeding shaft 45 is locked in the material-holding groove 51. The feeding shaft 45 pushes the feeding frame 5 containing the dental prosthesis mold to move to the right for cleaning. After the dental prosthesis mold is cleaned, the feeding motor 41 is controlled to stop working.

[0033] like Figures 7-9As shown, the cleaning and drying mechanism 7 includes a horizontal moving module 71, an adapter plate 72, a cleaning nozzle 73, a liquid inlet head 74, an air inlet head 75, an air suction head 76, and an external connector 77. The horizontal moving module 71 is horizontally fixed to the right side of the machine cover 2 via bolts. The adapter plate 72 is bolted to the slider of the horizontal moving module 71. The adapter plate 72 extends downward into the rear of the cleaning and drying zone 35. The cleaning nozzle 73 is horizontally mounted on the adapter plate 72, extending forward and backward. The cleaning nozzle 73 is located in the cleaning and drying zone 35, on the upper and lower sides of the conveying mechanism 4. The cleaning nozzle 73 has a liquid inlet head 74 and an air inlet head 75. The right side wall of the concave cover 31 is provided with an air suction head 76 and an external connector 77. The external connector 77 is connected to the liquid inlet head 74 via a pipeline. The external connector 77 is connected to an external water source, and the suction head 76 and the air inlet head 75 are connected by a pipeline. The suction head 76 is equipped with a suction fan. When the loading frame 5 containing the dental prosthesis mold passes through the cleaning and drying area 35, the horizontal moving module 71 drives the cleaning nozzle 73 to move left and right. At the same time, liquid enters the cleaning nozzle 73 through the external connector 77, pipeline and liquid inlet head 74. The cleaning nozzle 73 sprays water onto the dental prosthesis mold in the loading frame 5 to rinse the dental prosthesis mold. After the dental prosthesis mold is rinsed, the injection of liquid into the cleaning nozzle 73 stops. At this time, the suction head 76 is controlled to start working. Gas enters the cleaning nozzle 73 through the pipeline and air inlet head 75. The cleaning nozzle 73 sprays out the gas to dry the cleaned dental prosthesis mold.

[0034] like Figure 1 and Figure 2 As shown, in order to ensure the accuracy of material feeding, a limiting plate 6 is also included. The left side of the machine cover 2 on both the front and rear sides of the feeding frame 5 is provided with a limiting plate 6. The opposite side of the limiting plate 6 contacts the front and rear walls of the feeding frame 5, thereby limiting the front and rear position of the feeding frame 5 and ensuring that the feeding frame 5 can stably enter the conveying mechanism 4.

[0035] like Figure 10 and Figure 11As shown, in order to handle the wastewater from cleaning the dental prosthesis mold, a wastewater treatment mechanism 8 is also included. The wastewater treatment mechanism 8 is located on the right side of the cabinet 1. The wastewater treatment mechanism 8 includes a housing 81, a curing lamp 82, a wastewater inlet connector 83, a first baffle plate 84, a second baffle plate 85, an insert plate 86, a filter 87, and a drain pipe 88. The housing 81 is located on the right side of the cabinet 1. The wastewater inlet connector 83 is located on the upper wall of the housing 81. The wastewater inlet connector 83 is connected to the overflow connector 36, the first discharge connector 37, and the second discharge connector 39 through pipelines, so that the ultrasonic cleaning zone 32 and the cleaning... Liquid in the drying zone 35 can enter the chamber 81. A drainage channel is inclined at the top of the chamber 81. The wastewater inlet connector 83 is located above the highest point of the drainage channel. A curing lamp 82 is installed on the chamber 81 above the drainage channel. Symmetrically arranged insert plates 86 are positioned at the bottom of the drainage channel, and a filter 87 is slidably placed between the insert plates 86. An opening is provided in the drainage channel above the filter 87, allowing the filter 87 to communicate with the drainage channel. The lower wall of the chamber 81 is inclined, and a drain pipe 88 is located on the lowest side wall of the inclined section of the lower wall of the chamber 81. The drainage channel is located near the wastewater inlet connector. A first baffle plate 84 is provided in the filter 83. There is a gap between the bottom of the first baffle plate 84 and the lower wall of the drain channel. A second baffle plate 85 is provided in the drain channel, positioned above the filter 87. There is a gap between the second baffle plate 85 and the lower wall of the drain channel, and the bottom gap height of the second baffle plate 85 is less than the bottom gap height of the first baffle plate 84. The curing lamp 82 is positioned above the area between the first baffle plate 84 and the second baffle plate 85. The liquid in the ultrasonic cleaning zone 32 and the cleaning and drying zone 35 is discharged into the drain channel through a pipeline. The liquid in the drain channel passes through the first baffle plate 84. At 4 o'clock, the first baffle plate 84 spreads and disperses the flowing liquid, which is then discharged from the gap below the first baffle plate 84 into the area below the curing lamp 82. The curing lamp 82 cures the resin in the liquid, turning it into granules. The second baffle plate 85 allows the flowing liquid to stay below the curing lamp 82 for a longer time, ensuring that the resin in the liquid is fully cured. The liquid then enters the filter 87, which filters out impurities. The filtered liquid is discharged through the drain pipe 88. After the liquid treatment is completed, the filter 87 is removed, and the collected impurities are cleaned.
