Abstract

The application discloses a glue injection polymerization device, a glue injection system, a glue injection method and a wax removal device. The glue injection polymerization device comprises a pressure injection mechanism, and a polymerization mechanism is arranged below the pressure injection mechanism. The pressure injection mechanism is used for pushing the piston of a glue-containing syringe so that the glue is gradually injected into a false tooth model. The polymerization mechanism is used for providing steam so that the glue in the false tooth model is gradually polymerized from bottom to top. The glue injection polymerization device provided by the application realizes the combination of glue injection and glue boiling processes in one device. Since the polymerization mechanism is arranged below the glue pipe seat, the glue at the bottom of the false tooth model is first affected by high temperature to complete polymerization. In this process, the polymerized and solidified glue squeezes out the air in the glue, and this process gradually acts on the glue in the whole false tooth model from bottom to top, so that the generation of air bubbles can be effectively reduced or even avoided, the shrinkage rate of the glue support is reduced, the quality of the glue support after forming is improved, and the yield of the removable denture is improved.

Description

Technical Field

[0001] This invention relates to the technical field of denture manufacturing equipment and methods, and in particular to a glue injection polymerization device, glue injection system, glue injection method, and wax removal device. Background Technology

[0002] Removable dentures, also known as removable partial dentures or complete dentures, utilize the remaining natural teeth, the mucosa and bone tissue under the denture base for support, and rely on the denture retainers and base for retention. Artificial teeth restore the shape and function of missing teeth, and the base material restores the shape of the damaged alveolar ridge, jawbone and surrounding soft tissue. Patients can remove and insert the dentures themselves.

[0003] Taking removable partial dentures as an example, the fabrication process of removable dentures includes: replicating the model, making the wax pattern of the removable partial denture base, inserting the casting channel, embedding, baking, casting the removable partial denture framework, making the occlusal rim, arranging the artificial teeth, wax filling and glue injection, grinding and polishing; with the development of technology, the fabrication process of removable dentures has gradually been replaced by highly automated systems, such as glue injection systems, instead of a large amount of manual intervention.

[0004] The operation procedure of the dispensing system (including the pre-process) includes (please refer to the operation video and text instructions at the following link: https: / / mp.weixin.qq.com / s / lgAiCw7MKiIc6FaSGTNOYg):

[0005] Step 1: Observe the model, wax pattern, and occlusal relationship. Check if the model is damaged, if the wax pattern is intact, if there is enough space for glue application, and if the occlusal relationship is normal.

[0006] Step 2: Trim the model. Use a water mill to flatten the bottom of the plaster model and make it as small as possible.

[0007] Step 3: Draw the injection lines, one injection port and two exit ports. Use a five-point zero-wax line for the injection port and a four-point zero-wax line for the exit ports (the purpose is to distinguish between the injection port and the exit port). The injection port is placed on the lingual side of the anterior teeth, and the exit ports are placed on the posterior rim of the maxilla and on the posterior pad of the molars of the mandible.

[0008] Step 4: Plaster embedding. Use a prepared super-hard plaster (slightly fluid, but not too fluid) and brush a layer of plaster about two millimeters thick onto the denture base with the wax lines already laid (including the teeth, paying special attention to the tooth angles and gaps to ensure a tight fit). Then, use your hand to smooth out the functional tips of the teeth and apply a layer of glue to the exposed areas. After that, place the embedded model into the silicone mold and pour plaster into it until it is full.

[0009] Step 5: Boiling wax. Place the embedded model in 100-degree water to boil wax for ten minutes as usual. Then, use a steam gun to purge the wax from the glue inlet for about twenty seconds. After purging, use a syringe to inject the separator into the glue inlet (do not use a separator that causes severe gas formation). After filling, wait two or three seconds and then pour out the separator. Any residue inside can be blown out with an air gun. Then allow it to cool naturally.

[0010] Step 6: Prepare the adhesive. Prepare the adhesive by mixing water and powder in a 1:2 ratio. Stir gently, clockwise, two to four times until well mixed. Cover the container and wait for the adhesive to react, which takes about five minutes (depending on the temperature). When the adhesive has reacted to a consistency that is neither too thin nor too thick and has some fluidity, pour the prepared adhesive into the syringe, expel all air from the syringe, and then wait for the adhesive in the syringe to react to the point where it is ready for the stringing stage before injecting the adhesive.

[0011] Step 7: Apply glue. Place the syringe on the glue press machine, insert the injection port into the glue inlet, and then step on the foot pedal to start applying glue. Once the glue comes out of the outlet, you can slightly block the outlet with your hand.

[0012] Step 8: Boil the glue. Place the filled model in a pressure cooker and boil for 30 to 40 minutes before opening the box.

[0013] In the seventh step of glue injection, the glue is in a viscous liquid state, so it is necessary to slightly block the glue outlet with your hand to prevent the glue from flowing out and resulting in insufficient volume to form the glue tray. The eighth step of glue boiling is to speed up the solidification and molding of the glue tray. However, since air inevitably enters the glue during the injection process, the final glue tray will have more or less air bubbles. If there are too many air bubbles, the glue tray will not meet the quality standards and become a defective product. This has led to the problem of the high defect rate of existing removable dentures.

[0014] It is evident that existing technologies still need improvement and development. Summary of the Invention

[0015] In view of the shortcomings of the prior art, the purpose of this invention is to provide a glue injection polymerization device, a glue injection system, a glue injection method, and a dewaxing device, in order to solve the problem that in existing glue injection systems, air inevitably enters the glue during the glue injection process, resulting in more or less air bubbles in the final glue tray. Excessive air bubbles lead to substandard glue tray quality and defective products, resulting in a high defect rate of existing removable dentures.

[0016] The technical solution of this invention is as follows:

[0017] An injection polymerization apparatus includes: an injection mechanism, and a polymerization mechanism disposed below the injection mechanism. The injection mechanism is used to push the piston of the glue-containing syringe to gradually inject the glue into the denture model, and the polymerization mechanism is used to provide steam to gradually polymerize the glue in the denture model from bottom to top.

[0018] The advantages of the above solution are as follows: The glue injection and boiling process provided by this invention is integrated into one device. Since the polymerization mechanism is located below the glue tube seat, the lower glue in the denture model is first subjected to high temperature to complete the polymerization. During this process, the polymerized and solidified glue will squeeze out the air in the glue. This process acts on the glue in the entire denture model from bottom to top. On the one hand, it can effectively reduce or even avoid the generation of air bubbles, reduce the shrinkage rate of the glue tray, improve the quality of the molded glue tray, and thus improve the yield of removable dentures. On the other hand, there is no need to manually prevent the glue from flowing out, which reduces the errors that may occur due to manual intervention and reduces the amount of manual work. Furthermore, the integration of the two processes into one effectively improves the processing efficiency.

[0019] In a further preferred embodiment, the polymerization mechanism includes: a water storage tank, a water pump, a water pan, a heating component, and a liquid level sensor. The water pump is used to pump water from the water storage tank into the water pan, and the water pan is connected to a hose seat above it. The heating component is located inside the water pan and is used to heat the water in the water pan to generate steam. The liquid level sensor is connected to the water pump and is used to cooperate with the water pump to keep the liquid level in the water pan at a preset height.

[0020] The advantages of the above solution are as follows: First, the liquid level sensor ensures that the liquid level in the water pan remains within a certain range (for example, the preset liquid level height is set to 10 (this is just an example, so no specific unit is specified). Initially, after the water level reaches 10, the water pump stops working, and the heating component starts working. As the water continuously evaporates into steam and is constantly consumed, the liquid level continuously decreases. After it drops to 9, the liquid level sensor no longer detects liquid, and the water pump restarts, replenishing the water pan from the water tank until the liquid level returns to 10). It can be seen that since cold water is replenished after the water in the water pan evaporates, this invention controls the amount of cold water replenished each time through the liquid level sensor, thereby controlling the amount of steam to fluctuate only within a small range throughout the polymerization process, improving the polymerization effect and efficiency. Second, the liquid level sensor ensures that the water level in the water pan remains at the preset height regardless of the number of model boxes placed, thus ensuring that the water level is not affected by the number of models processed in each batch, maintaining the consistency of the quality of removable dentures processed in different batches.

[0021] In a further preferred embodiment, the aggregation mechanism further includes a cover that covers the water pan.

[0022] The above solution has two effects: 1. It fills the area below the cover and above the water surface in the water tray with steam, thereby increasing the polymerization speed of the colloid; 2. It prevents the colloid from being underheated due to excessively rapid heat exchange inside and outside the water tray, which would prevent the polymerized colloid from squeezing out air bubbles as much as possible, thus improving the polymerization effect of the colloid and improving the quality of the removable denture.

[0023] In a further preferred embodiment, the glue injection polymerization device further includes: a glue tube seat, which is sleeved on the outer edge of the glue-containing syringe and is made of a rigid material to prevent the glue-containing syringe from being damaged under the strong pressure of the injection mechanism.

[0024] The above solution has the following effect: during the injection process, the injection mechanism applies pressure to the piston. As the piston moves downward, it also transmits pressure to the wall of the glue-containing syringe due to deformation. Using rigid materials to make the syringe seat can effectively protect the glue-containing syringe and prevent it from undergoing plastic deformation or even breaking.

[0025] A dispensing system includes the dispensing polymerization apparatus as described above. Since the dispensing polymerization apparatus includes all the technical features of the dispensing system described above, it also includes all the technical effects of the dispensing system described above, and will not be elaborated further.

[0026] In a further preferred embodiment, the dispensing system further includes a dispensing shaker, which is used to drive the dispensing syringe to rotate or oscillate so that the liquid and powder in the dispensing syringe are fully mixed.

[0027] The effectiveness of the above solution lies in the following: From the description of step six (adhesive preparation) in the background section—"slightly stir, clockwise, two to four times"—it can be seen that traditional manual operation involves many unclear instructions. For example, the specific force and amplitude of "slightly" are not clearly defined. Furthermore, it's unclear whether "two to four times" refers to two, three, or four times. Depending on the operator or the force (number of stirrings) used each time, the prepared adhesive will vary. Moreover, stirring introduces air into the adhesive, resulting in a lack of consistency characteristic of industrial production. This obviously leads to inconsistent quality of removable dentures produced each time, resulting in a low product yield. This invention, through the design of the adhesive mixing machine, ensures high consistency in the rotation / oscillation amplitude of the adhesive-containing syringe each time, improving the consistency of removable denture product quality between different batches and the overall quality of each batch of removable dentures.

[0028] In a further preferred embodiment, the gel-shaping machine includes: a swing bracket, a rotation drive source, an L-shaped rotating shaft, a swing frame, and a sliding shaft. Two swing brackets are provided, arranged mirror-symmetrically, each with a rotating shaft hole and a sliding groove. Two L-shaped rotating shafts are provided, each inserted into one of the two rotating shaft holes, and either L-shaped rotating shaft passes through the rotating shaft hole and connects to the rotation drive source. Two sliding shafts are provided, each adapted to one of the two sliding grooves and fixed to both sides of the swing frame. The swing frame is used to accommodate the gel-containing syringe.

[0029] The effect of the above solution is that, by adopting the above structure, the glue-containing syringe moves in an "∞" trajectory under the combined action of the rotation drive source, the swing bracket, the L-shaped rotating shaft and the sliding shaft, so that the liquid and powder in the glue-containing syringe can be fully mixed.

[0030] In a further preferred embodiment, the dispensing system further includes a syringe refrigeration device, which is used to reduce the polymerization rate of the colloid in the dispensing syringe, and includes a refrigeration mechanism and several receiving cavities, the receiving cavities being used to contain the dispensing syringe.

[0031] The advantages of the above solution are as follows: Since the glue mixing machine needs a certain amount of time to mix the glue, and if the mixed glue cannot be used immediately, it is easy to polymerize in the glue-containing syringe, making it impossible to inject the glue; therefore, the present invention adopts a syringe refrigeration device, so that the glue mixing machine does not have to wait until the time of use to mix the glue, saving the time of mixing the glue on the spot and improving the processing efficiency of removable dentures.

[0032] In a further preferred embodiment, the glue injection system further includes a wax removal device, which is used for boiling wax, rinsing wax, injecting a separating agent into the denture model, and rinsing away excess separating agent to remove wax from the denture model.

[0033] The above solution has the following drawbacks: Based on the description of the fifth step of the background technology section, "Place the embedded model in 100-degree water to boil wax for ten minutes, then use a steam gun to flush the wax from the glue inlet for about twenty seconds. After flushing, use a syringe to inject the separator (do not use a separator that generates a lot of gas) into the glue inlet. After filling, wait two or three seconds and then pour out the separator. Any residue can be blown out with an air gun." The traditional wax boiling technique has the following defects: 1. It requires manual operation of the steam gun for wax flushing and air gun for removing the separator; 2. The manual operation instructions are unclear (using phrases like "about twenty seconds" and "after filling and waiting two or three seconds"), which can easily lead to incomplete wax removal, resulting in insufficient glue at the glue injection points due to the presence of wax, causing uneven surfaces on the bottom of the molded removable denture, rendering it a defective product; 3. It uses too much equipment, wasting a lot of time in the intermediate steps. This invention solves the above problems by using a wax removal device that integrates wax boiling, wax rinsing, and separating agent injection. Firstly, it reduces the required manpower; secondly, it eliminates the problem of removable dentures becoming waste products due to operators not knowing the operation time; and thirdly, it eliminates the need to switch between multiple devices, saving time and improving processing efficiency.

[0034] A glue injection method, implemented using the glue injection system described above, includes: a pressure injection mechanism pushing a piston of a glue-containing syringe to gradually inject the glue into a denture model, while a polymerization mechanism providing steam to gradually polymerize the glue within the denture model from bottom to top.

[0035] The advantages of the above solution are as follows: The injection method provided by this invention allows the denture model to be injected and polymerized simultaneously. During this process, the polymerized and solidified colloid will squeeze out the air in the colloid. This process acts on the colloid throughout the entire denture model from bottom to top. On the one hand, it can effectively reduce or even avoid the generation of air bubbles, reduce the shrinkage rate of the colloid, improve the quality of the molded colloid, and thus improve the yield rate of removable dentures. On the other hand, there is no need for manual prevention of colloid leakage, which reduces the errors that may occur due to manual intervention and reduces the amount of manual work. Furthermore, the integration of two processes into one effectively improves processing efficiency.

[0036] A glue injection method, implemented using a glue injection system, the glue injection system comprising: a glue shaker, a syringe refrigeration device, a dewaxing device, and a glue injection polymerization device, the glue injection method comprising the following steps:

[0037] The colloid shaker drives the glue-containing syringe to rotate or swing until the water and powder in the glue-containing syringe are fully mixed.

[0038] The receiving cavity inside the syringe refrigeration device accommodates the glue-containing syringe, and the refrigeration mechanism inside the syringe refrigeration device performs internal refrigeration.

[0039] The wax removal device is used to boil wax onto the denture model;

[0040] The dewaxing device uses water or steam to flush out the molten wax from inside the denture model;

[0041] The dewaxing device injects a separating agent into the denture model;

[0042] The wax removal device injects compressed air into the denture model;

[0043] The injection mechanism in the glue injection polymerization device pushes the piston of the glue-containing syringe to gradually inject the glue into the denture model. At the same time, the polymerization mechanism in the glue injection polymerization device provides steam to gradually polymerize the glue in the denture model from bottom to top.

[0044] The advantages of the above solution are as follows: The glue injection method adopted in this invention automates the processes of glue preparation, wax boiling, wax rinsing, injection of separating agent, rinsing out of separating agent, and simultaneous glue injection and polymerization through a glue shaker, syringe refrigeration device, wax removal device, and glue injection polymerization device. This greatly reduces the number of operators in the entire removable denture manufacturing process, thereby reducing the manufacturing cost of removable dentures. Moreover, it reduces defective products caused by human factors. Simultaneous pressure polymerization can reduce the shrinkage rate of the glue tray during polymerization, improving the product yield of removable dentures. In addition, it solves the problem that existing glue injection systems inevitably allow air to enter the glue during the injection process, resulting in more or less air bubbles in the final molded glue tray. Excessive air bubbles lead to substandard glue tray quality and defective products, resulting in a high defect rate of existing removable dentures.

[0045] A wax removal device includes: a water source, a wax boiling tank, a steam source, a flow channel cover, a separating agent source, and an air compressor; the wax boiling tank is connected to the water source and a wastewater tank, and is equipped with a water heating component inside for accommodating a denture model and wax boiling; the flow channel cover has a multi-functional flow channel, which is connected to the steam source, the separating agent source, and the air compressor and covers the wax boiling tank, for injecting steam, separating agent, and compressed air into the denture model to respectively achieve wax rinsing, separating agent injection, and model cleaning.

[0046] The advantages of the above solution are as follows: This invention integrates multiple processes such as wax boiling, wax rinsing, injection of separating agent and model cleaning into one device, which improves the integration, automation and intelligence of the glue injection system, greatly reduces the number of operators in the entire process of removable denture processing, thereby reducing the processing cost of removable dentures; moreover, it reduces defective products caused by human factors and improves the product yield of removable dentures.

[0047] In a further preferred embodiment, the lower end of the flow channel cover is connected to an elastic joint. The elastic joint is made of flexible material and has a trumpet-shaped lower end for abutting the injection port of the denture model. When the lower end of the elastic joint abuts against the denture model, the elastic joint is in a compressed state.

[0048] The above solution has the following effects: First, the flexible joint ensures that the denture model will not be damaged by collision. Second, by utilizing the characteristics of flexible materials and the trumpet-shaped lower end, the lower end of the flexible joint can cover the injection port of the denture model, thereby improving the sealing performance at the joint.

[0049] In a further preferred embodiment, the dewaxing device further includes: a clamping cylinder, wherein two clamping cylinders are provided, and the two clamping cylinders are respectively located on both sides of the flow channel cover plate, for clamping the flow channel cover plate after the denture model is placed into the wax boiling box.

[0050] The above solution has the following effect: the setting of the compression cylinder can ensure that the flow channel cover is tightly attached to the wax boiling box, which on the one hand prevents steam from overflowing and scalding the staff walking nearby, and on the other hand ensures that the elastic joint is compressed to further improve the sealing of the connection between the elastic joint and the denture model.

[0051] In a further preferred embodiment, the dewaxing device is applied to the adhesive dispensing system as described above.

[0052] Compared with existing technologies, the glue injection polymerization device provided by this invention includes: a pressure injection mechanism, below which a polymerization mechanism is disposed. The pressure injection mechanism is used to push the piston of the glue-containing syringe to gradually inject the glue into the denture model, and the polymerization mechanism is used to provide steam to gradually polymerize the glue in the denture model from bottom to top. The glue injection polymerization device provided by this invention integrates the glue injection and glue boiling processes into one device. Since the polymerization mechanism is located below the glue tube seat, the glue in the lower part of the denture model is first affected by high temperature to complete the polymerization. During this process, the polymerized and solidified glue will squeeze out the air in the glue. This process acts on the glue in the entire denture model from bottom to top, which can effectively reduce or even avoid the generation of air bubbles, reduce the shrinkage rate of the glue tray, improve the quality of the molded glue tray, and thus improve the yield of removable dentures. On the other hand, there is no need for manual prevention of glue leakage, which reduces the errors that may occur due to manual intervention and reduces the amount of manual work. Furthermore, integrating the two processes into one effectively improves processing efficiency. Attached Figure Description

[0061] This invention provides a glue injection polymerization device, a glue injection system, a glue injection method, and a dewaxing device. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and examples.

[0062] To address the problem that existing glue injection systems inevitably introduce air into the glue during the injection process, resulting in varying degrees of air bubbles and deformation in the final molded denture. Excessive air bubbles or deformation lead to substandard denture quality and a high defect rate in current removable dentures; this invention provides a glue injection polymerization device, such as... Figure 1As shown, the glue injection polymerization device includes an injection mechanism 110 and a polymerization mechanism 130. The polymerization mechanism 130 is located directly below the injection mechanism 110, with a working space 120 between them to prevent the glue-containing syringe ZT from being injected. The polymerization mechanism 130 has a cavity for containing water and the denture model MX. The injection mechanism 110 is used to push the piston of the glue-containing syringe ZT to gradually inject the glue into the denture model MX, and the polymerization mechanism 130 is used to provide steam to gradually polymerize the glue in the denture model MX from bottom to top. In other words, when the injection mechanism 110 pushes the piston of the glue-containing syringe ZT downward to inject the glue inside the syringe into the denture model MX (or before or after a certain time, the fluidity of the glue needs to be maintained before the glue reaches the designated position; since the polymerization of the glue takes a certain amount of time, the polymerization mechanism 130 can start water heating at the same time as or before and after the injection mechanism 110 starts pushing the glue-containing syringe ZT downward), the polymerization mechanism 130 simultaneously starts to provide steam to achieve the effect of simultaneous glue injection and polymerization. On the one hand, this can effectively reduce or even avoid the generation of air bubbles, improve the quality of the molded glue base, and thus improve the yield rate of removable dentures; on the other hand, there is no need to manually prevent the glue from flowing out, which reduces the errors that may occur due to manual intervention and reduces the amount of manual work; furthermore, integrating two processes into one effectively improves processing efficiency. Therefore, the injection polymerization device provided by the present invention solves the problem that in the existing injection system, air inevitably enters into the glue during the injection process, resulting in more or less air bubbles and deformation of the final molded glue tray. Too many air bubbles or deformation of the glue tray will lead to substandard glue tray quality and defective products, resulting in a high defect rate of existing removable dentures.

[0063] In a further preferred embodiment, such as Figure 2 As shown, the polymerization mechanism 130 includes: a water storage tank (not shown), a water pump (not shown), a water tray 131, a heating component 132, and a liquid level sensor (not shown). The water pump is used to pump water from the water storage tank into the water tray 131, which is connected to a hose seat above it. The heating component 132 is located inside the water tray 131 and is used to heat the water in the water tray 131 to generate steam. The liquid level sensor is connected to the water pump and is used to work with the water pump to keep the liquid level in the water tray 131 at a preset height.

[0064] Before using the injection and polymerization device for injection and polymerization, the denture model MX must first be placed in the water tray 131. Then, preferably, the outlet of the glue-containing syringe ZT should be aligned with the glue inlet of the denture model MX (this is preferred because many structures can inject the glue from the syringe ZT into the denture model MX, such as using a frame suspended between the water tray 131 and the injection mechanism 110 to align the syringe ZT with the denture model MX without applying its own weight to the model). At least the denture model MX will cause the water level in the water tray 131 to rise. The height of the rise will vary depending on the number of denture models MX being processed at one time. Furthermore, during injection and polymerization, the water in the water tray 131 will continuously evaporate into steam, causing the water level to continuously decrease. Although this process is very slow, the injection of cold water will also lower the water temperature in the water tray 131, thus affecting the processing effect of the denture model MX.

[0065] Therefore, by adopting the above structure, the present invention achieves the following effects: First, the liquid level sensor ensures that the water level in the water pan 131 remains at a preset height regardless of the number of model boxes placed, thus ensuring that the water level is not affected by the number of models processed in each batch, maintaining the consistency of the quality of removable dentures processed in different batches; Second, the liquid level sensor keeps the liquid level in the water pan 131 fluctuating within a certain range (for example, the preset liquid level height is set to 10 (this is just an example, so no specific unit is set). Initially, after the water level reaches 10, the water pump stops working, and the heating component 132 starts working. As the water continuously evaporates into steam and is constantly consumed, the liquid level continues to decrease. After it drops to 9, the liquid level sensor can no longer detect liquid, and the water pump restarts, drawing water from the water tank to replenish the water pan 131 until the liquid level reaches 10 again). It can be seen that since cold water is replenished after the water in the water pan 131 evaporates, the present invention controls the amount of cold water replenished each time through the liquid level sensor, thereby controlling the amount of steam to fluctuate only within a small range during the entire polymerization process, improving the polymerization effect and polymerization efficiency.

[0066] Furthermore, the present invention also includes a temperature sensor installed inside the water pan. This temperature sensor controls the water temperature within the pan and works in conjunction with a level sensor to control the water level. In practice, the polymerization time is only calculated after the cold water is heated to a certain temperature, for example, 95°C. Heating stops when the temperature reaches 98°C because boiling water causes agitation, which in turn changes the water level. When the water level falls below the low level, cold water is automatically added; when the water temperature drops below 95°C, heating is automatically initiated.

[0067] Furthermore, the aggregation mechanism 130 also includes a cover 140, which covers the water tray 131. Figure 3As shown, a heat-insulating handle 141 is provided on the cover 140, and the heat-insulating handle 141 is made of heat-insulating materials such as rubber. It is understood that without the cover 140, the steam generated by the heating component 132 heating the water will quickly dissipate into the air, preventing the steam from fully contacting the denture model MX, greatly reducing the polymerization efficiency of the colloid. Furthermore, the steam cannot remain in the water tray 131, and the temperature inside the water tray 131 will decrease due to rapid heat exchange with the outside environment, significantly reducing the polymerization effect of the colloid. Therefore, by providing the cover 140, this invention achieves the following technical effects: 1. It fills the area below the cover 140 and above the water surface of the water tray 131 with steam, increasing the polymerization speed of the colloid; 2. It prevents excessively rapid heat exchange inside and outside the water tray 131, which could lead to insufficient heating of the colloid, preventing the polymerized colloid from squeezing out air bubbles as much as possible, thus improving the polymerization effect of the colloid and consequently improving the quality of the removable denture.

[0068] Preferably, the dispensing polymerization device further includes a tubing seat (not shown), which is sleeved on the outer edge of the glue-containing syringe ZT and is made of a rigid material (such as thick nylon or stainless steel, which does not need to be too thick), to prevent the glue-containing syringe ZT from being damaged under the strong pressure of the injection mechanism 110. During the dispensing process, the injection mechanism 110 applies pressure to the piston. As the piston moves downward, it also transmits pressure to the wall of the glue-containing syringe due to deformation. Using a rigid material to make the tubing seat can effectively protect the glue-containing syringe ZT and prevent it from undergoing plastic deformation or even breaking.

[0069] In specific implementation, such as Figure 3 As shown, the dispensing mechanism includes a cylinder 111 and a semi-flexible material sleeve 112. The cylinder 111 is preferably a linear cylinder 111 and is hung upside down on the frame of the dispensing polymerization device. The semi-flexible material sleeve 112 is sleeved on the outer edge of the output shaft end of the cylinder 111 to prevent the output shaft of the cylinder 111 from damaging the piston of the glue-containing syringe ZT.

[0070] The present invention also provides a dispensing system comprising the dispensing polymerization apparatus as described above. Since the dispensing polymerization apparatus includes all the technical features of the dispensing system described above, it also includes all the technical effects of the dispensing system described above, and will not be elaborated further.

[0071] In a further preferred embodiment, such as Figure 4 As shown, the dispensing system further includes a dispensing machine 200, which is used to drive the glue-containing syringe ZT to rotate or swing, so as to fully mix the liquid and powder in the glue-containing syringe ZT.

[0072] The description of step six (adhesive preparation) in the background section, "slightly stir, clockwise, two to four times," reveals numerous unclear operational instructions in traditional manual processes. For example, the specific force and amplitude of "slightly" are not clearly defined, and it's unclear whether "two to four times" refers to two, three, or four times. Depending on the operator or the force (number of stirrings) used each time, the prepared adhesive will vary, lacking the high consistency required for industrial production. This obviously leads to inconsistent quality of removable dentures produced each time, resulting in a low product yield. This invention, through the setting of the adhesive shaking machine 200, ensures high consistency in the rotation / oscillation amplitude of the adhesive-containing syringe ZT each time, improving the product quality consistency of removable dentures between different batches and the overall quality of each batch of removable dentures.

[0073] Furthermore, such as Figure 4 As shown, the glue-shaping machine 200 includes: a swing bracket 250, a rotation drive source 210, an L-shaped rotating shaft 220, a swing frame 230, and a sliding shaft 240. Two swing brackets 250 are provided, arranged in a mirror-symmetrical manner, and each swing bracket 250 has a rotating shaft hole 251 and a sliding groove 252. Two L-shaped rotating shafts 220 are provided, each inserted into one of the two rotating shaft holes 251, and either L-shaped rotating shaft 220 passes through the rotating shaft hole 251 and connects to the rotation drive source 210. Two sliding shafts 240 are provided, each adapted to one of the two sliding grooves 252, and are fixed to both sides of the swing frame 230. The swing frame 230 is used to accommodate the glue-containing syringe ZT. By employing the above-described structure, the present invention enables the glue-containing syringe ZT to move along an "∞" trajectory under the combined action of the swing frame 230, the rotation drive source 210, the swing bracket 250, the L-shaped rotating shaft 220, and the sliding shaft 240, thereby ensuring that the water and powder inside the glue-containing syringe ZT are fully mixed.

[0074] According to another aspect of the invention, the dispensing system further includes: a syringe cooling device 300, such as... Figure 5 As shown, the syringe refrigeration device 300 is used to reduce the polymerization rate of the colloid in the glue-containing syringe ZT. It includes a refrigeration mechanism (not shown, but a conventional refrigerator refrigeration mechanism can be used) and several receiving cavities (not shown, the cavities filled with the glue-containing syringe ZT are the receiving cavities), which are used to contain the glue-containing syringe ZT. Since the glue mixing machine 200 requires a certain amount of time to prepare the glue, and if the prepared colloid cannot be used immediately, it is easy to polymerize in the glue-containing syringe ZT, making glue injection impossible; therefore, this invention uses the syringe refrigeration device 300, so that the glue mixing machine 200 does not have to wait until use to prepare the glue in advance, saving the glue mixing time of the glue mixing machine 200 on-site and improving the processing efficiency of removable dentures.

[0075] According to another aspect of the invention, the dispensing system further includes: a wax removal device 400, such as... Figure 6 As shown, the wax removal device 400 is used for boiling wax, rinsing wax, and injecting a separating agent into the denture model MX to remove wax from the denture model MX. From the description of the fifth step, boiling wax, in the background section: "Place the embedded model in 100-degree water to boil wax normally for ten minutes. Then, use a steam gun to rinse the wax from the glue inlet for about twenty seconds. After rinsing, use a syringe to inject the separating agent (do not use a separating agent that generates a lot of gas) into the glue inlet. After filling, wait two or three seconds and then pour out the separating agent. Any residue can be blown out with an air gun." It can be seen that the traditional wax boiling technique has the following defects: 1. It requires manual operation of the steam gun for rinsing wax and air gun for rinsing out the separating agent; 2. The manual operation instructions are unclear (using phrases like "about twenty seconds" and "after filling and waiting two or three seconds"), which easily leads to incomplete wax removal, resulting in insufficient glue at the locations where glue should be injected, causing unevenness on the bottom surface of the molded removable denture, making it a defective product; 3. Too much equipment is used, and a lot of time is wasted in the intermediate transitions. The present invention solves the above problems by using a wax removal device 400 that integrates wax boiling, wax rinsing and separating agent injection. Firstly, it reduces the required manpower; secondly, it eliminates the problem of removable dentures becoming waste products due to operators not knowing the operation time; and thirdly, it eliminates the need to transfer between multiple devices, saving time and improving processing efficiency.

[0076] This invention also provides a glue injection method, implemented using the glue injection system described above. The method includes: a pressure injection mechanism 110 pushing a piston of a glue-containing syringe ZT to gradually inject the glue into the denture model MX; simultaneously, a polymerization mechanism 130 providing steam to gradually polymerize the glue within the denture model MX from bottom to top. The glue injection method provided by this invention allows the denture model MX to be injected and polymerized simultaneously. During this process, the polymerized and solidified glue will expel air from the glue body. This process acts gradually from bottom to top on the glue within the entire denture model MX, effectively reducing or even eliminating the generation of air bubbles, improving the quality of the molded adhesive, and thus increasing the yield rate of removable dentures. Furthermore, it eliminates the need for manual prevention of glue leakage, reducing errors that may occur due to human intervention and reducing manual workload. Finally, integrating two processes into one effectively improves processing efficiency.

[0077] This invention also provides a glue injection method, which utilizes a glue injection system. The glue injection system includes: a glue shaker 200, a syringe refrigeration device 300, a dewaxing device 400, and a glue injection polymerization device. The glue injection method includes the following steps (please refer to the appendix). Figures 1 to 8 ):

[0078] S1. The shaking machine 200 drives the glue-containing syringe ZT to rotate or swing until the water and powder in the glue-containing syringe ZT are fully mixed, as described in the above device embodiment, and will not be repeated here;

[0079] S2. The receiving cavity inside the syringe refrigeration device 300 accommodates the glue-containing syringe ZT, and the refrigeration mechanism inside the syringe refrigeration device 300 performs internal refrigeration of the syringe refrigeration device 300, as described in the above device embodiment, and will not be described again.

[0080] S3. The wax removal device 400 boils wax on the denture model MX, as described in the above device embodiment, and will not be repeated here.

[0081] S4. The wax removal device 400 uses water or steam to flush out the molten wax inside the denture model MX, as described in the above device embodiment, and will not be repeated here.

[0082] S5. The dewaxing device 400 injects a separating agent into the denture model MX, as described in the above device embodiment, and will not be repeated here.

[0083] S6. The dewaxing device 400 injects compressed air into the denture model MX, as described in the above device embodiment, and will not be repeated here.

[0084] S7. The injection mechanism 110 in the glue injection polymerization device pushes the piston of the glue-containing syringe ZT to gradually inject the glue into the denture model MX. At the same time, the polymerization mechanism 130 in the glue injection polymerization device provides steam to gradually polymerize the glue in the denture model MX from bottom to top. The specific details are as described in the above device embodiment and will not be repeated.

[0085] The glue injection method employed in this invention automates the processes of glue preparation, wax boiling, wax rinsing, injection of separating agent, rinsing out separating agent, and simultaneous glue injection and polymerization via a glue shaker 200, a syringe refrigeration device 300, a wax removal device 400, and a glue injection polymerization device. This significantly reduces the number of operators involved in the entire removable denture manufacturing process, thereby lowering the manufacturing cost of removable dentures. Furthermore, it reduces defective products caused by human factors, improving the product yield of removable dentures. In addition, it solves the problem that existing glue injection systems inevitably allow air to enter the glue during the injection process, resulting in varying degrees of air bubbles and deformation in the final molded denture. Excessive air bubbles or deformation can lead to substandard quality and defective products, resulting in a high defect rate for existing removable dentures.

[0086] The present invention also provides a wax removal device 400, which includes: a water source (not shown separately), a wax boiling tank 410, a steam source (not shown separately), a flow channel cover 420, a separating agent source 450, and an air compressor; the water source is used to provide water for wax boiling (it can also provide steam water; of course, the steam water can be provided separately from the steam source or can be taken from the water source, the present invention does not specifically limit this); the steam source is used to provide steam for rinsing the wax, and the separating agent source 450 is used to provide the separating agent for injection; preferably, it also includes a wastewater tank. The wastewater tank is used to hold the wastewater after rinsing the wax and the separating agent. The wax boiling tank 410 is connected to the water source and the wastewater tank, and is equipped with a water heating component 132 inside, which is used to hold the denture model MX and the wax. The flow channel cover plate 420 has a multi-functional flow channel, which is connected to the steam source, the separating agent source 450 and the air compressor and covers the wax boiling tank 410. It is used to inject steam, separating agent and compressed air into the denture model MX to realize wax rinsing, separating agent injection and model cleaning respectively.

[0087] This invention integrates multiple processes such as wax boiling, wax rinsing, injection of separating agent, and model cleaning into one device, improving the integration, automation, and intelligence of the glue injection system. This greatly reduces the number of operators in the entire removable denture processing process, thereby reducing the processing cost of removable dentures. Moreover, it reduces defective products caused by human factors and improves the product yield of removable dentures.

[0088] In specific implementation, the water source is set as a hot water heating inner tank 440 (e.g., Figure 7 and Figure 8 As shown, the hot water heating inner tank provides both hot water and steam, which can be achieved through various solutions such as setting outlets at different heights (the specific solution is not limited). The dewaxing device 400 is equipped with a hot water steam solenoid valve 460, a wax boiling tank water supply solenoid valve 470, a wax boiling tank drain solenoid valve 480, and an inner tank water inlet solenoid valve 490. The four solenoid valves are respectively used to guide steam into the flow channel cover plate 420, supply water to the wax boiling tank 410, drain water from the wax boiling tank 410, and inlet water into the inner tank.

[0089] In a further preferred embodiment, the lower end of the flow channel cover 420 is connected to a flexible joint 421, such as... Figure 6 As shown, the elastic joint 421 is made of flexible material and has a flared lower end for abutting the glue injection port of the denture model MX. When the lower end of the elastic joint 421 abuts against the denture model MX, the elastic joint 421 is in a compressed state. The design of the elastic joint 421 ensures that the denture model MX will not be damaged by impact, and also utilizes the characteristics of the flexible material and the flared lower end to ensure that the lower end of the elastic joint can cover the glue injection port of the denture model MX, thereby improving the sealing performance at the joint.

[0090] Preferably, the dewaxing device 400 further includes: a clamping cylinder 430, such as... Figure 6 As shown, two clamping cylinders 430 are provided, located on opposite sides of the flow channel cover plate 420. These cylinders are used to clamp the flow channel cover plate 420 after the denture model MX is placed in the wax boiling tank 410. The clamping cylinders 430 ensure that the flow channel cover plate 420 is tightly attached to the wax boiling tank 410, preventing steam overflow and burns to nearby personnel. They also ensure that the elastic joint 421 is compressed to further improve the sealing at the connection between the elastic joint 421 and the denture model MX.

[0091] It should be noted that the dewaxing device provided by the present invention can be applied to the glue injection system as described above. Therefore, the glue injection system can have all the technical features and effects of the dewaxing device, which will not be elaborated further.
