Description

Technical Field

[0001] The present application relates to the technical field of resin processing, and in particular to a composite equipment for processing model resins. Background Art

[0002] The denture base is the basic framework of the denture, located on the alveolar ridge and mucosa in the oral cavity, and plays the role of support, retention, connection and aesthetics. It not only ensures the stability and functionality of the denture, but also protects the oral tissue, improves the service life and wearing comfort of the denture. Therefore, the design of the denture base and the selection of materials are crucial to the overall quality of the denture and the patient's usage experience.

[0003] The processing and molding of denture bases is a complex and delicate process involving multiple steps. Strict operation and quality control are required from design to final molding. The processing process is mainly divided into the design stage and the processing stage. Among them, the processing stage can be divided into heat treatment and curing molding of the resin model base to make it into a denture base model resin. After molding, the model resin needs to be trimmed and polished. During trimming and polishing, sandpaper and polishing wheels of different mesh sizes are generally used to finely grind and polish the cured resin base.

[0004] The existing grinding process generally uses different grinding heads or polishing heads for grinding according to the grinding process flow. During the replacement, the efficiency is low, and during grinding, the grinding equipment is subjected to greater wear and tear, and the grinding head needs to be replaced frequently, resulting in a short service life. Summary of the Invention

[0007] By adopting the above scheme, by arranging coaxial first, second and third telescopic joints on the same rotating drive member, and correspondingly arranging first, second and third polishing members on the three, when the denture base needs to be polished in batches, the coolant can be pumped between the second telescopic joint and the third telescopic joint, or into the second telescopic joint and the first telescopic joint, so as to control the corresponding second telescopic joint to drive the second polishing member to extend, or the first telescopic joint to drive the first polishing member to extend, so that the device can perform different processes of polishing and polishing on the denture base conveniently and efficiently by extending different polishing members on the same rotating drive member, reducing the time required for replacing polishing members, and at the same time, when the coolant passes into the telescopic joint, the heat in the coolant can be quickly discharged to reduce the loss of polishing members and telescopic joints caused by heat accumulation.

[0008] In one embodiment of the present application, a three-axis linear module is provided at the top of the inner wall of one side of the equipment box, the slider on the three-axis linear module is connected and fixed to the rotating drive component, and a placement base is provided under the equipment box, which is configured to place the model resin.

[0009] By adopting the above solution, a three-axis linear module is set up and the three-axis linear module is used to drive the rotating drive component to adjust its position inside the equipment box, so that the device can adjust the grinding position of the rotating drive component, i.e., the grinding component, according to the shape of the model resin, to ensure the fineness of the grinding and polishing.

[0010] In one embodiment of the present application, an annular opening is provided on the outside of one end of the third telescopic joint along its own annular direction, and the third telescopic joint is fixedly connected to connecting columns at intervals at the annular opening, and the third telescopic joint is coaxially rotatably assembled with a rotating ring on the outside of the annular opening, and a water inlet channel and a water outlet channel connected to the third telescopic joint are provided on both sides of the rotating ring, the liquid supply equipment is connected to the water inlet channel through an inlet pipe, and the liquid supply equipment is connected to the water outlet channel through an outlet pipe, an inlet valve is provided inside the water inlet channel, and a water outlet valve is provided inside the water outlet channel, and the third polishing part is coaxially arranged on the outside of the third telescopic joint.

[0011] By adopting the above solution, an annular opening is arranged outside the third telescopic section and fixed by a connecting column. At the same time, a rotatable rotating ring is arranged on the annular opening and connected to the water inlet pipe and the water outlet pipe. The water inlet pipe and the water outlet pipe can not only pump the coolant into the third telescopic section, but also generate a certain traction force on the rotating ring, so that it will not rotate with the rotation of the third telescopic section, thus ensuring that the third telescopic section can normally drive the third grinding member to rotate and grind the model resin.

[0012] In one embodiment of the present application, the second telescopic section is arranged inside the third telescopic section and is slidably sealed with the third telescopic section. A second channel is provided on the inner wall of one end of the second telescopic section. The third telescopic section and the second telescopic section are communicated through the second channel. A second control valve is provided inside the second channel. The second grinding member is coaxially arranged outside the other end of the second telescopic section. A third receiving cavity configured to receive the second grinding member is coaxially opened on the end face of the other end of the third telescopic section; The first telescopic section is arranged inside the second telescopic section and is slidably sealed with the second telescopic section. A first channel is provided on the inner wall of one end of the first telescopic section. The second telescopic section and the first telescopic section are communicated through the first channel. A first control valve is provided inside the first channel. The first grinding member is coaxially arranged outside the other end of the first telescopic section. A second receiving cavity configured to receive the first grinding member is coaxially opened on the end face of the other end of the second telescopic section; The first telescopic section, the second telescopic section and the third telescopic section are all heat-conducting metal components.

[0013] By adopting the above solution, when the first grinding member needs to be extended, the coolant is pumped into the first telescopic section, the second telescopic section and the third telescopic section, so that the first telescopic section can extend. Under the control of the three-axis moving module, it drives the rotation driving member to move in the equipment box and perform primary grinding on the denture base. After the primary grinding, the coolant between the first telescopic section and the second telescopic section can be controlled to be pumped out. After the coolant is pumped out, the external atmospheric pressure presses the first telescopic section back into the second telescopic section. At this time, the coolant between the second telescopic section and the third telescopic section is continuously kept under pressure. At this time, the second telescopic section is controlled to rotate, and then the second grinding member can be controlled to polish the model resin. When three times of polishing are required, the coolant inside the second telescopic section and the third telescopic section is also pumped out, and the third telescopic section is driven to rotate to drive the third grinding member to polish the model resin. During the process of pumping the coolant in and out, the coolant can timely take away the heat generated by grinding in the first telescopic section, the second telescopic section and the third telescopic section, and avoid the increase in loss caused by heat accumulation.

[0014] In one embodiment of the present application, the liquid supply device includes: A water tank, wherein the interior of the water tank is filled with coolant and a plurality of cooling fins are mounted on the exterior of the water tank; A water pump is provided on one side of the outer wall of the water tank and is connected to the water tank, and one end of the water inlet pipe and one end of the water outlet pipe are both connected to one end of the water tank; The other end of the water tank is connected to a second water inlet pipe and a second water outlet pipe. The interior of the placement base is hollow, and one end of the second water inlet pipe and the second water outlet pipe is connected to the placement base.

[0015] By adopting the above solution, the water pump can pump the coolant in the water tank into the polishing workpiece and circulate it, so that the coolant can take away the heat accumulated in the polishing workpiece during polishing during the circulation process, thereby improving the heat dissipation capacity of the polishing workpiece.

[0016] In one embodiment of the present application, the placement base includes: A base body, wherein a communication cavity is formed inside the base body, and two groups of water outlet holes are provided on the inner wall of the base body above the communication cavity, each group of the water outlet hole groups includes a plurality of water outlet holes spaced apart in a circular array, and the two groups of the water outlet hole groups are concentrically arranged, and a water outlet control valve is provided between the communication cavity and the water outlet holes; A push rod, the push rod is arranged inside the water outlet and is slidably sealed with the water outlet; A placement substrate comprises a placement plate and a deflection member, wherein the placement plate is arranged on the deflection member, and the deflection member is arranged on the base body. The placement plate is configured to be arranged at an angle to the base body, and a plurality of top rods and the deflection member contact each other to maintain the angle of the placement plate.

[0017] By adopting the above solution, the water pump can not only pump the coolant into the polishing workpiece, but also pump the coolant into the ejector rod. By controlling the water outlet control valves at different positions, the ejection of the ejector rods at different positions can be controlled, so that the ejector rods can be ejected upward and squeeze and resist different positions of the deflection member. The deflection member can drive the substrate to be fixed at different angles to cope with the complex surface shape of the model resin.

[0018] In one embodiment of the present application, the deflection member includes: A fixing frame with a spherical chamber inside, the fixing frame is fixedly assembled to the base body; The ball is provided inside the fixing frame, one end of the ball protrudes from the fixing frame and is fixedly connected to a hemispherical body, and one end of the hemispherical body is connected and fixed to the placement plate.

[0019] By adopting the above solution, by setting the ball, the ball can rotate in the spherical chamber inside the fixed frame. During the rotation process, it can drive the hemispherical body to deflect, and it can also rotate itself, thereby driving the placement substrate to adjust the angle and elevation angle.

[0020] In one embodiment of the present application, the equipment box further includes a dust removal device, and the dust removal device includes: A filter element, the filter element includes a filter housing and at least two layers of filter meshes. A strip-shaped opening is provided at the bottom end of one side of the equipment box, the filter housing is assembled at the strip-shaped opening, and at least two layers of the filter meshes are arranged on the inner wall of the filter housing and are spaced apart along the width direction of the filter housing; An exhaust fan, a strip-shaped through hole is provided at the top end of the other side of the equipment box, and the exhaust fan is assembled on the inner wall of the equipment box and is located on the strip-shaped through hole.

[0021] By adopting the above solution, when grinding the model resin, turning on the exhaust fan can introduce external air flow from the lower part of the equipment box. After being filtered by the filter element, the external cold air can discharge the dust generated by grinding from the strip-shaped through hole. At the same time, when the cold air passes through the grinding part, it can accelerate the heat loss of the grinding part and avoid the influence of the residual dust and residue on the grinding part on the model resin.

[0022] In one embodiment of the present application, a disc cavity is provided inside the bottom end of the equipment box. Two connection channels respectively communicating with the second water inlet pipe and the second water outlet pipe are provided on one inner wall of the equipment box. The connection channels communicate with the disc cavity. A circular opening is provided at the bottom wall of the equipment box below the disc cavity, and an elastic pad is provided inside the circular opening.

[0023] By adopting the above solution, since the inside of the equipment box itself is filled with coolant, during the grinding process, the elastic pad can deform according to the unevenness of the placement surface, thereby improving the placement stability of the device. At the same time, the coolant can absorb the vibration generated during grinding, thereby reducing the noise generated by the device during grinding.

[0024] In one embodiment of the present application, the fixed frame is fixedly assembled on the inner wall of the bottom end of the equipment box, and the water outlet hole is located on the inner wall of the bottom end of the equipment box and communicates with the disc cavity.

[0025] By adopting the above solution, introducing the coolant into the inner wall of the bottom end of the equipment box can not only improve the stability of the equipment box during placement, but also by setting the fixed frame at the bottom end of the equipment box, the water outlet hole communicates with the communication cavity, so that the device will not affect the normal ejection of the ejector rod.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting a coaxial first telescopic joint, a second telescopic joint and a third telescopic joint, and using a hydraulic method to control the opening and closing of the first control valve, the second control valve and the third control valve, the extension of the first telescopic joint, the second telescopic joint and the third telescopic joint are controlled, thereby controlling the first polishing part, the second polishing part or the third polishing part to polish the model resin, avoiding the trouble of frequent replacement of polishing parts. At the same time, by pumping in or out the coolant, the coolant takes away the friction heat generated by the first polishing part, the second polishing part and the third polishing part during polishing, thereby reducing the loss of the polishing parts during polishing.

[0027] 2. By setting a deflection member, when polishing the model resin, the model resin is assembled on the placement base plate. When the three-axis moving module is used to drive the polishing drive member to move, the pitch angle and deflection angle of the model resin can be adjusted by adjusting the rotational orientation of the ball inside the fixed frame. In addition, the coolant hydraulic method is also used to lift the ejector pin, and the ejector pin is used to support different positions of the hemispherical body, so that the hemispherical body can be fixed at a certain angle and posture, so that the position of the placement base plate can be quickly fixed, so that the device can perform detailed polishing according to the complex shape and curve of its own surface during polishing.

[0028] 3. By installing an exhaust fan and setting the position of the inlet and outlet of the equipment box, the flow direction of the external cold air inside the equipment box can be adjusted. This allows the device to control the external cold air to pass through the model resin and sweep away the dust generated during the polishing of the model resin. At the same time, the external cold air can also be used to cool the polished parts, further reducing the loss of the polished parts during polishing. BRIEF DESCRIPTION OF THE DRAWINGS

Since the first polishing member 224 is provided on the first expansion joint 221 and the first expansion joint 221 is located at the lowermost end of the entire polishing member, the second polishing member 225 and the third polishing member 226 will not interfere with the polishing work of the first polishing member 224. At this time, by turning on the rotary drive member 21, the first expansion joint 221, the second expansion joint 222, and the third expansion joint 223 can be driven to rotate, and then the model resin can be initially polished using the first polishing member 224; After the initial polishing is completed, control the water pump 34 to extract the coolant inside the polishing member until the first expansion joint 221 and the second expansion joint 222 retract into the third expansion joint 223. After the coolant is extracted, close the first control valve 2211 and the second control valve 2221, and re-introduce the coolant between the second expansion joint 222 and the third expansion joint 223. At this time, the second expansion joint 222 extends from the third expansion joint 223, so that the model resin can be polished using the second polishing member 225 outside the second expansion joint 222; After the secondary polishing is completed, continue to extract the coolant. At this time, close the inlet valve 2234 and the outlet valve 2235, and the model resin can be polished using the third polishing member 226 outside the third expansion joint 223.

[0046] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
