Description

Technical Field

[0001] This invention belongs to the field of dental prosthesis processing technology, specifically relating to a multi-stage polishing system for dental prostheses. Background Technology

[0002] Dentures are artificial teeth that replace missing natural teeth. During the denture manufacturing process, they need to be polished. Most of the polishing equipment in the current technology is single-stage polishing, which is not good for polishing the detailed structure of dentures. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is: how to provide a multi-stage polishing system for dentures to achieve multi-stage polishing of dentures.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A multi-stage polishing system for dentures includes:

[0006] A conveying channel, wherein the conveying channel is circular;

[0007] Several denture mounting frames are provided, which are used to fix the dentures during the polishing process. The denture mounting frames are all slidably disposed within the conveying channel.

[0008] At least two grinding mechanisms are provided, which are used to grind the denture. The grinding mechanisms are all located above the conveying channel. Each grinding mechanism includes a grinding tool, and the roughness of the grinding tool of each grinding mechanism decreases sequentially along the conveying direction of the denture on the conveying channel.

[0009] A denture transfer mechanism is provided, which drives the denture mounting frame to move along the conveying channel. The denture transfer mechanism includes a drive shaft and a transfer element fixed on the drive shaft. The drive shaft coincides with the axis of the conveying channel. The transfer element includes a transfer arm and a gripping part disposed at the outer end of the transfer arm. When the transfer arm rotates in the same direction as the conveying channel, the gripping part can push the denture mounting frame to move in the conveying channel. When the transfer arm rotates in the opposite direction to the conveying channel, the gripping part slides past the denture mounting frame. The denture mounting frames corresponding to each level of the polishing mechanism abut against each other or are spaced apart by at least one denture mounting frame.

[0010] Preferably, the denture mounting frame includes a frame structure formed by connecting a first straight portion, a first arcuate portion, a second straight portion, and a second arcuate portion end to end. The first straight portion and the second straight portion both extend radially along the transmission channel, and the first arcuate portion and the second arcuate portion are respectively attached to the inner side of the outer ring and the inner ring of the transmission channel.

[0011] Preferably, the first arc-shaped portion has a strip-shaped gripping hole on the side facing the drive shaft, and the gripping part can be inserted into the gripping hole. When the gripping part abuts against the end of the gripping hole during the rotation with the drive shaft, the gripping part pushes the denture mounting frame to move within the transmission channel.

[0012] Preferably, the gripping hole is located above the top of the conveying channel.

[0013] Preferably, the denture mounting frame is provided with two clamping elements for clamping and fixing the denture.

[0014] Preferably, the clamping element includes a clamping block, which is elastically connected to the gripping hole along the radial direction of the conveying channel by an elastic element, and the two clamping elements are respectively located on the first arc-shaped portion and the second arc-shaped portion.

[0015] Preferably, the multi-stage polishing system for dentures further includes a feeding mechanism located downstream of the polishing mechanism. The feeding mechanism includes a feeding port at the bottom of the conveying channel. When the clamping element releases its grip on the denture, the denture falls from the feeding port.

[0016] Preferably, the feeding mechanism further includes a clamping and releasing element for driving the clamping element to release its gripping of the denture. The clamping and releasing element includes guide posts fixed to the two clamping blocks respectively, an outer ring guide groove formed on the outer ring of the conveying channel, and an inner ring guide groove formed on the inner ring of the conveying channel. When the denture mounting frame moves within the conveying channel, the two guide posts can be inserted into the outer ring guide groove and the inner ring guide groove respectively, so that the two clamping blocks move away from each other.

[0017] Preferably, the guide post is located above the gripping hole.

[0018] Preferably, the conveying channel further includes a feeding area located downstream of the discharge port.

[0019] The beneficial effects of this invention are as follows:

[0020] This invention, through its multi-stage polishing mechanism, enables multi-stage polishing of dentures, resulting in excellent polishing effects. Furthermore, the use of a ring-shaped conveyor channel for transferring and conveying the dentures saves installation space. After polishing, automatic unloading is achieved, demonstrating a high degree of automation. Attached Figure Description

[0064] Please see Figure 1 This embodiment provides a multi-stage denture polishing system, including a conveying channel 6, several denture mounting frames 5, at least two-stage polishing mechanisms, a denture transfer mechanism, a material unloading mechanism, and a base 1.

[0065] Combination Figure 1 and Figure 7 As shown, the conveying channel 6 is annular, having an outer ring 61 and an inner ring 62. Between the outer ring 61 and the inner ring 62 is a recessed area, which forms the conveying channel 6 for conveying several denture mounting frames 5. The bottom of the conveying channel 6 is fixedly mounted to the base 1 by four support columns 2.

[0066] The denture mounting frame 5 is used to fix the denture during the polishing process, and the denture mounting frame 5 is slidably disposed within the conveying channel 6. The structure of the denture mounting frame 5 is combined... Figure 2 and Figure 5 As shown, the denture mounting frame 5 includes a frame body 51 and two clamping elements 52 disposed within the frame body 51.

[0067] The frame body 51 is a fan-shaped frame structure formed by connecting the first straight part 511, the first arc-shaped part 513, the second straight part 512 and the second arc-shaped part 514 end to end. The first straight part 511 and the second straight part 512 both extend radially along the conveying channel 6. The first arc-shaped part 513 and the second arc-shaped part 514 are respectively attached to the inner side of the outer ring 61 and the inner ring 62 of the conveying channel 6.

[0068] Two clamping elements 52 are used to clamp and fix the denture. The structure of the clamping elements 52 is combined. Figure 2 and Figure 6As shown, the clamping element 52 includes a clamping block 521 and an upper slider 522 and a lower slider 523 located on the outer side of the clamping block 521. The first arcuate portion 513 and the second arcuate portion 514 of the denture mounting frame 5 each have an upper slotted hole 515 and a lower slotted hole 516, both located above the top of the conveying channel 6. The upper slider 522 is radially slidably connected to the upper slotted hole 515 along the conveying channel 6, and the lower slider 523 is radially slidably connected to the lower slotted hole 516 along the conveying channel 6. The two clamping elements 52 are elastically slidably connected to the denture mounting frame 5 by two elastic elements, both of which are compression springs. Figure 2 As shown, when the two clamping elements 52 clamp the denture within the denture mounting frame 5, the outer end of the upper slider 522 extends out of the outer side of the denture mounting frame 5, and the outer end of the lower slider 523 is located inside the outer side of the denture mounting frame 5, so that a strip-shaped gripping hole is formed between the outer end of the lower slider 523 and the outer side of the denture mounting frame 5.

[0069] This embodiment features a two-stage polishing mechanism for polishing dentures. Both mechanisms are positioned above the conveying channel 6 (not shown in the figure). Each stage includes a polishing tool, and the roughness of the tools decreases sequentially along the conveying direction of the denture on the conveying channel 6. Each stage corresponds to a denture mounting frame 5, used to polish the denture held within the mounting frame 5 below it. The two corresponding denture mounting frames 5 below the two stages abut against each other or are spaced apart by at least one denture mounting frame 5. In this embodiment, the two corresponding denture mounting frames 5 below the two stages are spaced apart by one denture mounting frame 5 to ensure sufficient installation space for both stages.

[0070] The denture transfer mechanism drives the denture mounting frame 5 to move along the transfer channel 6. The mechanism includes a drive shaft 3 and a transfer element 4 fixed to the drive shaft 3. The drive shaft 3 coincides with the axis of the transfer channel 6. A motor (not shown in the figure) is installed inside the base 1. The output shaft of the motor is fixedly connected to the bottom of the drive shaft 3, driving the drive shaft 3 to rotate in both forward and reverse directions. The transfer element 4 is structurally integrated... Figure 1 , Figure 3 and Figure 4 It includes a transfer arm 42, a mounting ring 41 fixed to the inner end of the transfer arm 42, and a gripping part 43 disposed at the outer end of the transfer arm 42. The mounting ring 41 is fixed on the drive shaft 3 and rotates with the rotation of the drive shaft 3. The gripping part 43 can be inserted into the gripping hole. During the forward rotation with the drive shaft 3, when the gripping part 43 abuts against the end of the gripping hole, the gripping part 43 pushes the denture mounting frame 5 to move within the transfer channel 6.

[0071] The gripper 43 structure is as follows Figure 4 As shown, it includes a gripping shaft 431 fixedly connected to the outer end of the transfer arm 42, and a gripper 432 rotatably connected to the gripping shaft 431. A torsion spring is also connected to the gripper 432 and the gripping shaft 431. When the transfer arm 42 rotates in the same direction as the conveying channel 6, the gripper 432 abuts against the end of the gripping hole, pushing the denture mounting frame 5 to move within the conveying channel 6. When the transfer arm 42 rotates against the conveying direction of the conveying channel 6, the gripper 432 slides past the gripping hole. To ensure that the gripper 432 can push the denture mounting frame 5 when the transfer arm 42 rotates in the same direction as the conveying channel 6, a blocking plate 433 is provided on the gripper 432, and a blocking mating post 420 is fixed to the outer end of the transfer arm 42. Through the cooperation between the blocking plate 433 and the blocking mating post 420, it is ensured that the gripper 432 can push the denture mounting frame 5 when the transfer arm 42 rotates in the same direction as the conveying channel 6.

[0072] The unloading mechanism is located downstream of the grinding mechanism. The unloading mechanism includes an unloading port 600 at the bottom of the conveying channel 6. When the clamping element 52 releases its grip on the denture, the denture falls from the unloading port. The unloading mechanism also includes a clamping release element for driving the clamping element 52 to release its grip on the denture. The clamping release element includes guide posts 524 fixed to the two clamping blocks 521, an outer ring track 64 fixed to the outer ring 61 of the conveying channel 6, and an inner ring track 63 fixed to the inner ring 62 of the conveying channel 6. The outer ring track 64 has an outer ring guide groove 640, and the inner ring track 63 has an inner ring guide groove 630. The guide post 524 is located at the bottom of the upper slider 522 and outside the denture mounting frame 5. The guide post 524 is also located above the gripping hole to avoid affecting the movement of the gripping part 43 within the gripping hole. When the denture mounting frame 5 moves within the conveying channel 6, the two guide posts 524 can be inserted into the outer ring guide groove 640 and the inner ring guide groove 630 respectively, causing the two clamping blocks 521 to move away from each other, thereby loosening the clamping of the denture. The conveying channel 6 also includes a loading area located downstream of the unloading port 600. After the clamping element 52 loosens its clamping of the denture, the denture to be ground can be placed into the denture mounting frame 5 in the loading area, and the denture can be clamped again by the two clamping blocks 521. When the denture moves to the bottom of the grinding mechanism, the grinding mechanism grinds the denture.

[0073] The specific implementation process of this embodiment is as follows:

[0074] After the denture mounting frame 5, to which the denture is fixed, is conveyed to the grounding mechanism, the first-stage grounding mechanism first performs the first grinding. After the first grinding is completed, the drive shaft 3 rotates forward at a certain angle, and the gripping part 43 drives the denture mounting frame 5 to move to the grounding mechanism of the second-stage grounding mechanism, which then performs the second grinding on the denture.

[0075] After the next denture is polished by the first-stage polishing mechanism, it is pushed by the gripping part 43 to the bottom of the second-stage polishing mechanism. The denture that was originally located below the second-stage polishing mechanism is pushed forward by the next denture, thereby realizing the transmission of the denture mounting frame 5 in the transmission channel 6.

[0076] When the denture moves above the discharge port 600, the guide posts 524 on the two clamping blocks 521 enter the inner ring guide groove 630 and the outer ring guide groove 640 respectively, causing the two clamping blocks 521 to move away from each other, thereby releasing the denture and causing it to fall from the discharge port.

[0077] The above are merely preferred embodiments of the present invention. It should be noted that any modifications and improvements made by those skilled in the art without departing from the present technical solution should also be considered to fall within the scope of protection claimed in this claim.
