Description

Technical Field

[0001] The present invention relates to the technical field of denture base manufacturing, and specifically relates to an automatic dropping and spraying forming device for denture bases. Background Art

[0002] In the field of denture manufacturing, an automatic dropping and spraying forming device for denture bases is used for the production of denture bases and is a key device to ensure the quality and performance of dentures. This device mainly sprays and drops self-curing water and self-curing powder onto a mold in a certain proportion and manner, enabling them to interact and form, thereby providing a support structure for the denture. Its working principle is to use a mechanical device to control the conveying and dropping process of the materials to achieve the automated production of denture bases. In the modern field of oral rehabilitation, this device is of great significance for improving the production efficiency of dentures, ensuring the consistency of denture quality, and meeting the growing needs of patients.

[0003] However, there are many drawbacks in the traditional method of manufacturing denture bases. On the one hand, manual operation relies on manual experience. When spraying and dropping self-curing water and self-curing powder, it is difficult to ensure the uniform distribution of the materials, resulting in uneven thickness of the denture base, affecting the comfort and stability of denture wearing, and with low manufacturing accuracy and high scrap rate. On the other hand, some traditional manufacturing methods require the use of equipment such as light-curing machines, which not only have cumbersome operations, increase the manufacturing process and time costs, but also raise the production cost, and are not conducive to the large-scale development of the denture manufacturing industry. In addition, traditional equipment lacks an effective automatic adjustment and control mechanism, is unable to accurately control the dropping amount of self-curing water and self-curing powder, is prone to material waste or shortage, and it is also difficult to clean the residual materials inside the equipment, easily causing pipeline blockage, affecting the normal operation and service life of the equipment, and urgently needs to be improved to meet the requirements of modern denture production. Summary of the Invention

[0005] The present invention provides an automatic dropping and spraying forming device for denture bases, which solves the problems mentioned in the above background art.

[0008] A dropping and spraying mechanism, which is fixedly installed on the top plate;

[0009] An auxiliary mechanism, which is fixedly installed on the dropping and spraying mechanism;

[0010] Among them, the dripping mechanism includes a hydraulic cylinder, which is fixedly embedded in the middle upper surface of the top plate. The output end of the hydraulic cylinder is fixedly connected with a pressing rod, and the bottom of the pressing rod is fixedly connected with an adjusting column. The upper surface of the adjusting column is symmetrically provided with material leakage holes, and the top of the material leakage holes is fixedly communicated with a feeding hose. The top of one of the feeding hoses is fixedly communicated with a self-curing water storage tank, and the top of the other feeding hose is fixedly communicated with a self-curing powder storage tank. The self-curing water storage tank is fixedly embedded through the upper surface of one side of the top plate, and the self-curing powder storage tank is fixedly embedded through the upper surface of the other side of the top plate.

[0011] Preferably, a driving rod is slidably connected through the middle upper surface of the adjusting column. The top of the driving rod is fixedly connected with a top ring through a connecting rod. The lower surface of the top ring is symmetrically fixedly connected with connecting plates, and the bottom of the connecting plates is fixedly connected with electromagnetic rings. Initially, the electromagnetic rings are arranged below the adjusting column.

[0012] Preferably, the outer surface of the driving rod is provided with threads, and the outer surface of the driving rod is threadedly connected with a rotating wheel. The upper and lower surfaces of the rotating wheel are rotatably connected inside the adjusting column, and the outer surface of the rotating wheel is rotatably connected with a transmission belt. The two ends of the transmission belt are rotatably connected with a diffusion pipe.

[0013] Preferably, the diffusion pipe is rotatably connected to the inner surface of the bottom of the material leakage hole, and the bottom of the diffusion pipe is fixedly communicated with a guiding pipe, and the guiding pipe is inclined.

[0014] Preferably, the auxiliary mechanism includes a first installation groove, which is opened on the top of the adjusting column. An upper adjusting disc is arranged inside the first installation groove, and the middle of the upper adjusting disc is threadedly connected to the outer surface of the top of the driving rod.

[0015] Preferably, a second installation groove is opened in the middle of the adjusting column, and the second installation groove is arranged directly below the first installation groove. A lower adjusting disc is arranged inside the second installation groove, and the middle of the lower adjusting disc is threadedly connected to the outer surface of the middle of the driving rod.

[0016] Preferably, an upper adjusting hole is opened on the upper surface of the upper adjusting disc, and the upper adjusting hole initially coincides with the material leakage hole communicated with the self-curing water storage tank. A lower adjusting hole is opened on the upper surface of the lower adjusting disc, and the lower adjusting hole is initially arranged at a 90-degree angle offset from the upper adjusting hole.

[0017] Preferably, the bottom of the driving rod is fixedly connected with a pressing disc, and the upper surface of the edge of the pressing disc is fixedly connected with a corrugated pipe.

A plurality of expansion rings are fixedly arranged at fixed intervals along the central axis of the adjustment column.

If it is necessary to manufacture a denture base, the mold can be placed under the dropping mechanism on the bottom plate, and the whole device can be placed in a sealed space. Then, the hydraulic cylinder can be driven to work to push the adjustment column downward, so that the adjustment column moves above the mold. Then, self-curing water is introduced onto the mold through the self-curing water storage tank and the leakage holes. After the introduction of the self-curing water is completed, self-curing powder is introduced onto the self-curing water just introduced onto the mold through the self-curing powder storage tank and the leakage holes until the previously dropped liquid is fully swollen. Finally, when the surface of the denture base turns white, the forming of the denture base is completed.

[0019] (III) Beneficial effects

[0020] The present invention provides a denture base automatic dropping and forming device, which has the following beneficial effects:

[0021] (I). This denture base automatic dropping and forming device uses conventional self-curing resin powder and liquid on the market, automatically completes the dropping of self-curing water and self-curing powder in a sealed environment, and accurately spreads through the rotation of the model, with the shape being easy to control, reducing the operation time and material volatilization. At the same time, the denture base is quickly formed, with the thickness being easy to control, and it avoids the problems of complicated operation in the market for making denture bases and high production costs caused by the use of a light curing machine. When the hydraulic cylinder drives the dropping mechanism to move downward, the electromagnetic ring at the bottom will first contact the bottom plate and be firmly magnetically adsorbed to the bottom plate. At this time, as the hydraulic cylinder continues to work, the driving rod connected to the top ring will gradually move upward out of the adjustment column. The adjustment column is fixed by the extrusion rod, so the driving rod moves vertically upward relative to the adjustment column. Then, the rotating wheel starts to rotate through the thread. As the rotating wheel rotates, the transmission belt starts to rotate, and the diffusion pipes on both sides are driven to rotate through the transmission belt. Finally, the guiding pipe at the bottom of the diffusion pipe rotates. By setting the guiding pipe obliquely, when the guiding pipe rotates around the central axis of the diffusion pipe, it rotates within a circular range, so that when self-curing water and self-curing powder are introduced onto the mold, the self-curing water and self-curing powder can be evenly dropped on the mold through the rotation of the guiding pipe, greatly improving the manufacturing accuracy of the denture base, making its thickness more uniform, facilitating the overall control of the thickness of the denture base, and improving the forming speed of the denture base.

[0022] (2) The original denture base automatic dropping and forming device. When the driving rod moves upward, it will simultaneously drive the upper adjusting disc and the lower adjusting disc to start rotating through the thread. Among them, the upper adjusting hole on the upper adjusting disc is aligned with the leakage hole of the self-curing water at the beginning, that is, initially the leakage hole of the self-curing water is in communication with the self-curing water storage tank. As the upper adjusting disc rotates, the leakage hole of the self-curing water will gradually be closed, and the leakage hole of the self-curing powder will be gradually opened. That is, by rotating the upper adjusting disc, the self-curing water and the self-curing powder are successively released into the leakage hole. When the upper adjusting hole is misaligned with the leakage hole of the self-curing water, the lower adjusting hole on the lower adjusting disc gradually approaches the leakage hole of the self-curing water and finally aligns with it, releasing the self-curing water in the leakage hole into the diffusion tube. That is, when the hydraulic cylinder works, the self-curing water and the self-curing powder are automatically released in segments, which can avoid the problem that it is difficult to control the quality of the base due to too much or too little of the self-curing water and the self-curing powder being released at one time. At the same time, it can also automatically open and close the self-curing water storage tank and the self-curing powder storage tank, and improve the working stability of the device through multi-stage release.

[0023] (3) The original denture base automatic dropping and forming device. When the driving rod moves upward relative to the adjusting column, it will synchronously drive the extrusion disc at its bottom to move upward, that is, start to extrude the corrugated pipe, so that the air pressure in the internal cavity of the corrugated pipe increases and is conveyed to the expansion bladder, prompting the expansion bladder to expand outward, and then causing the expansion ring to expand towards the central axis of the lower adjusting disc, and further causing the stopper on the side surface of the lower adjusting disc to gradually contact and squeeze the expansion ring. That is, when releasing the self-curing water and the self-curing powder, the intermittent vibration of the lower adjusting disc during rotation is achieved through the expansion of the expansion ring, so that the self-curing water and the self-curing powder in the diffusion tube and the guiding tube are vibrated and cleaned. This can not only further ensure the amount of self-curing water and self-curing powder released at one time, but also avoid the problem of blockage inside the diffusion tube and the guiding tube, greatly improving the working stability of the device.

[0039] The outer surface of the driving rod 38 is provided with threads. The outer surface of the driving rod 38 is threadedly connected with a rotating wheel 312. The upper and lower surfaces of the rotating wheel 312 are rotatably connected inside the adjusting column 33. The outer surface of the rotating wheel 312 is rotatably connected with a transmission belt 313. The two ends of the transmission belt 313 are rotatably connected with a diffuser pipe 314.

[0040] The diffuser pipe 314 is rotatably connected to the inner surface of the bottom of the material leakage hole 34. The bottom of the diffuser pipe 314 is fixedly communicated with a guiding pipe 315, and the guiding pipe 315 is inclined.

[0041] Second Embodiment: As Figures 1 to 8 shown, the auxiliary mechanism 4 includes a first installation groove 41, and the first installation groove 41 is opened at the top of the adjusting column 33. An upper adjusting disc 42 is arranged inside the first installation groove 41. The middle part of the upper adjusting disc 42 is threadedly connected to the outer surface of the top of the driving rod 38.

[0042] A second installation groove 43 is opened in the middle part of the adjusting column 33. The second installation groove 43 is arranged directly below the first installation groove 41.

[0043] An upper adjusting hole 45 is penetrated and opened on the upper surface of the upper adjusting disc 42. The upper adjusting hole 45 initially coincides with the material leakage hole 34 communicated with the self-curing water storage tank 36. A lower adjusting hole 46 is penetrated and opened on the upper surface of the lower adjusting disc 44.

[0046] During operation, if the baseplate needs to be manufactured, the mold can be placed under the dropping mechanism 3 on the bottom plate 1, and the entire device can be placed in a sealed space. Then, the hydraulic cylinder 31 can be driven to work, pushing the adjustment column 33 downward to move it above the mold. Next, self-curing water is introduced onto the mold through the self-curing water storage tank 36 and the leakage hole 34. After the introduction of self-curing water is completed, self-curing powder is then introduced onto the just-introduced self-curing water on the mold through the self-curing powder storage tank 37 and the leakage hole 34 until the previously dropped liquid is fully swollen. Finally, the surface of the baseplate turns white, indicating the completion of the formation of the denture baseplate. The present invention uses commercially available conventional self-curing resin powder and liquid, automatically completes the dropping of self-curing water and self-curing powder in a sealed environment, precisely spreads through the rotation of the model, is easy to control the shape, reduces the operation time and material volatilization. At the same time, the baseplate is formed quickly, is easy to control the thickness, and avoids the problem of the complicated operation of manufacturing the baseplate in the market and the high production cost caused by the use of a light-curing machine. When the hydraulic cylinder 31 drives the dropping mechanism 3 to move downward, the electromagnetic ring 311 at the bottom will first contact the bottom plate 1 and firmly magnetically adsorb to the bottom plate 1. At this time, as the hydraulic cylinder 31 continues to work, the driving rod 38 connected to the top ring 39 will gradually move upward out of the adjustment column 33. Since the adjustment column 33 is fixed by the extrusion rod 32, the driving rod 38 moves vertically upward relative to the adjustment column 33, and then drives the rotating wheel 312 to start rotating through the thread. As the rotating wheel 312 rotates, the transmission belt 313 will start to rotate, and the diffusion pipes 314 on both sides will be driven to rotate via the transmission belt 313. Finally, the guiding pipe 315 at the bottom of the diffusion pipe 314 rotates. By setting the guiding pipe 315 obliquely, when the guiding pipe 315 rotates around the central axis of the diffusion pipe 314, it rotates within a circular range, so that when self-curing water and self-curing powder are introduced onto the mold, the rotation of the guiding pipe 315 causes the self-curing water and self-curing powder to be evenly dropped on the mold, greatly improving the manufacturing accuracy of the baseplate, making its thickness more uniform, facilitating the overall control of the thickness of the baseplate, and improving the forming speed of the baseplate. When the driving rod 38 moves upward, it will simultaneously drive the upper adjustment disc 42 and the lower adjustment disc 44 to start rotating through the thread. Among them, the upper adjustment hole 45 on the upper adjustment disc 42 is aligned with the leakage hole 34 of self-curing water initially, that is, initially the leakage hole 34 of self-curing water is in communication with the self-curing water storage tank 36. As the upper adjustment disc 42 rotates, the leakage hole 34 of self-curing water will be gradually closed, and the leakage hole 34 of self-curing powder will be gradually opened, that is, by rotating the upper adjustment disc 42, self-curing water and self-curing powder are successively released into the leakage hole 34. When the upper adjustment hole 45 is misaligned with the leakage hole 34 of self-curing water, the lower adjustment hole 46 on the lower adjustment disc 44 gradually approaches the leakage hole 34 of self-curing water and finally aligns with it, releasing the self-curing water in the leakage hole 34 into the diffusion pipe 314, that is, automatically and segmentally releasing self-curing water and self-curing powder during the operation of the hydraulic cylinder 31.That is, it can avoid the problem that it is difficult to control the quality of the base due to excessive or insufficient release of self-curing water and self-curing powder at one time. At the same time, it can also automatically open and close the self-curing water storage tank 36 and the self-curing powder storage tank 37, and improve the working stability of the device through multi-stage release. When the driving rod 38 moves upward relative to the adjusting column 33, it will synchronously drive the extrusion disc 47 at its bottom to move upward, that is, start to extrude the corrugated pipe 48, so that the air pressure in the internal cavity of the corrugated pipe 48 increases and is conveyed to the expansion bladder 410, prompting the expansion bladder 410 to expand outward, and then causing the expansion ring 49 to expand toward the central axis of the lower adjusting disc 44. Furthermore, the stoppers on the side surface of the lower adjusting disc 44 gradually come into contact with and extrude the expansion ring 49, that is, when releasing the self-curing water and self-curing powder, the intermittent vibration of the lower adjusting disc 44 occurs during rotation due to the expansion of the expansion ring 49, so that the self-curing water and self-curing powder in the diffusion pipe 314 and the guiding pipe 315 are vibrated and cleaned. This can not only further ensure the amount of self-curing water and self-curing powder released at one time, but also avoid the problem of blockage inside the diffusion pipe 314 and the guiding pipe 315, greatly improving the working stability of the device.
